`CROSS REFERENCE TO RELATED APPLICATIONS
`
`This application claims priority to Chinese Patent Application No. 201720926752.X,
`
`filed July 27, 2017, the contents of such application being incorporated by reference herein.
`
`BACKGROUND OF THE INVENTION
`
`Field of the Invention
`
`The present disclosure relates to a ventilating device and more particularly to a
`
`ventilating device with a temperature/humidity sensor.
`
`Description of the Related Art
`
`Fig.1 is a schematic diagram of a connection between a sensor and a circuit board
`
`box in a ventilating device in a related art. As shown in Fig. 1, in the ventilating device 10 of
`
`the related art, in order to more accurately detect temperature or humidity of air entering
`
`from an air inlet, a sensor 1 that senses the temperature or humidity is provided at a place
`
`proximate to the air inlet. However, since the sensor 1 needs to be connected with the
`
`circuit board so as to be controlled and be powered by the same, in the related art, a circuit
`
`board (not shown) with a terminal (not shown) is provided in a circuit board box 2, and a
`
`lead 3 is used to connect the sensor 1 to a terminal.
`
`However, since the circuit board and the sensor 1 are connected via the lead 3, when
`
`the sensor needs maintenance, the lead 3 connected to the circuit board should be removed
`
`before removing the sensor 1 from a frame 4. Similarly, when the circuit board needs
`
`

`

`CSPT—153US
`
`PATENT
`
`maintenance, the lead 3 connected to the sensor 1 should be removed before removing the
`
`circuit board box 2 provided with the circuit board. That is, work or operation may not be
`
`performed conveniently before the maintenance is actually performed.
`
`SUMMARY OF THE INVENTION

`a terminal connected to the air blower and provided on the control circuit board, the control
`
`circuit board and a lead of the air blower being connected to each other through the
`
`terminal; and an operation opening provided in the circuit board box and opposite to the
`
`terminal.
`
`In an embodiment of the present disclosure, the ventilating device further comprises
`
`a cover for covering the operation opening; and an insertion opening for guiding the lead to
`
`the circuit board box.
`
`In an embodiment of the present disclosure, the air blower comprises: a motor; a

`
`wherein, the circuit board box is provided between the third side surface and the air blower
`
`or between the fourth side surface and the air blower.
`
`In an embodiment of the present disclosure, the ventilating device further comprises
`
`

`

`CSPT—153US
`
`PATENT
`
`a first air path for communicating the air inlet with the first air suction port; and a second

`
`In an embodiment of the present disclosure, a first end of the sensor storage unit is
`
`provided on a wall of the circuit board box, and a second end of the sensor storage unit
`
`extends outwards from the circuit board box.
`
`In an embodiment of the present disclosure, the air entrance port is provided at the
`
`second end.
`
`(III) Benefits
`
`As can be seen from the above technical solution, the ventilating device of the
`
`present disclosure has at least one of the following beneficial effects:
`
`(1) The circuit board box and the sensor storage unit are integrally formed into one
`
`piece. When the sensor or the control circuit board needs to be maintained or removed, by
`
`only removing the circuit board box integrally molded with the sensor storage unit, the
`
`sensor or the control circuit board may be maintained or replaced as required without being
`
`assembled or disassembled separately, thereby easing their replacements and reducing
`
`

`

`CSPT—153US
`
`PATENT
`
`labor—hours. At the same time, only one mold may be used to create the sensing unit and
`
`the circuit board box, which can save the mold cost. It can be seen that with such a design,
`
`it can simultaneously achieve the effects of easy assembly and disassembly of the
`
`components, improving the convenience of maintenance and saving cost.
`
`(2) The circuit board box is disposed in a space between the third side surface and
`
`the air blower, or a space between the fourth side surface and the air blower, that is, the
`
`circuit board box is disposed in a space with a small air flow, and the effect of the circuit
`
`board box upon the air flow may be minimized, so that the circuit board box may be
`
`provided without affecting an air volume.
`
`(3) In order to facilitate maintenance of the circuit board box, an operation opening
`
`is provided at a position opposite to the terminal provided on the control circuit board, and
`
`the lead connected with the air blower can be freely attached to or detached from the
`
`control circuit board through the operation opening.
`
`When it is necessary to remove the circuit board box, as long as the cover covered
`
`on the operation opening is opened, the terminal connected with the lead will be exposed,
`
`and the maintenance personnel may remove the lead from the terminal through the
`
`operation opening. In this way, the circuit board box is no longer connected to the air blower,
`
`and the maintenance personnel may entirely remove the circuit board box from the frame.
`
`In addition, the lead may be inserted into the circuit board box through the insertion
`
`opening provided on the wall of the circuit board box, and the lead may be fixed on the
`
`insertion opening by pressing the cover on an opened portion of a notch, thereby facilitating
`
`assembly and maintenance.
`
`

`

`CSPT—153US
`
`PATENT
`
`(4) The distance L1 from the first air suction port to the top surface is greater than
`
`the distance L2 from the second air suction port to the bottom surface. With such a design,
`
`the sensor storage unit is provided in the second air path.
`
`When the motor is disposed at the first air suction port side, and the distance from
`
`the first air suction port to the top surface is greater than the distance from the second air
`
`suction port to the bottom surface, the amount of air entering the air blower from the first
`
`air suction port is less than that entering the air blower from the second air suction port,
`
`that is, the air volume flowing through the first air path is less than the air volume flowing
`
`through the second air path. In addition, since the motor is disposed in the first air path, the
`
`resistance of the first air path is relatively larger and the turbulence is relatively more. Since
`
`the air volume flowing through the second air path is more and the turbulence is relatively
`
`less, the sensor storage unit is disposed in the second air path, so that the humidity and the
`
`temperature may be correctly sensed, thereby improving the accuracy of the temperature
`
`and humidity sensed by the sensor storage unit.
`
`(5) The first end of the sensor storage unit is disposed on the wall of the circuit
`
`board box, and the second end extends outwards from the circuit board box, and the air
`
`entrance port is disposed at the second end. With the above structure, the air entering the
`
`frame from the air inlet flows directly to the air entrance port opposite to the air inlet. The
`
`humidity and temperature of the air entering the frame may be more quickly and accurately
`
`detected by the sensor provided in the sensor storage unit. In addition, the air entrance port
`
`is provided on the second end of the sensor storage unit extending outwards from the
`
`circuit board box. In this way, the second end is closer to the air blower or the air inlet side,
`
`and more air enters the sensor storage unit. Therefore, although the circuit board box is
`
`

`

`CSPT—153US
`
`PATENT
`
`provided in a space with a small airflow, the sensor may accurately detect the humidity and
`
`temperature of the air entering the frame, ensuring the accuracy of the temperature and
`
`humidity sensed by the sensor.

`
`DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
`
`The present disclosure provides a ventilating device that can use less components,
`
`facilitate assembly and disassembly of components, and improve maintenance convenience
`
`by reasonably setting the positions of the circuit board box and the sensor storage unit.
`
`To make the purpose, technical solutions, and advantages of the present application
`
`clearer, the following further describes the present disclosure in detail with reference to
`
`specific embodiments and the accompanying drawings.
`
`In an exemplary embodiment of the present disclosure, a ventilating device is
`
`provided. Fig. 2 is a schematic structural view of a ventilating device with a bottom surface
`
`

`

`CSPT—153US
`
`PATENT
`

`
`removed according to an embodiment of the present disclosure. Fig. 3 is a schematic
`
`diagram of the ventilating device shown in Fig. 2 viewed from the top surface side with a
`
`top surface and a filter unit removed. As shown in Fig. 2, the ventilating device in this
`
`embodiment includes a frame 100, an air blower 200, a sensor 820, a filter unit 600, a
`
`circuit board box 700, and a sensor storage unit 800. Among them, the circuit board box
`
`700 and the sensor storage unit 800 are integrally molded into one piece. Among them, the
`
`circuit board box 700 is configured to store the control circuit board 720. The sensor storage
`
`unit 800 is configured to store a sensor 820 connected to the control circuit board 700 and
`
`capable of sensing humidity or temperature.
`
`With the above configuration, when the sensor or the control circuit board needs to
`
`be maintained or removed, by only removing the circuit board box 700 integrally molded
`
`with the sensor storage unit 800, the sensor 800 or the control circuit board 720 then may
`
`be maintained or replaced as required without being assembled or disassembled separately,
`
`thereby easing their replacements and reducing labor-hours. At the same time, only one
`
`mold may be used to create the sensing unit and the circuit board box, which can save the
`
`mold cost. Due to easy assembly and disassembly of the components and the convenient
`
`maintenance, it may achieve the effect of saving cost.
`
`The various components of the ventilating device in the present embodiment will be
`
`described in detail with reference to the accompanying drawings.
`
`Referring to Figs. 2 and 3, the frame 100 is of a hollow rectangular parallelepiped
`
`shape, including a top surface 111, a bottom surface 116 facing the top surface 111, and
`
`four side surfaces adjacent to the bottom surface 116 and the top surface 111, which are a
`
`

`

`CSPT—153US
`
`PATENT
`
`l 1
`
`first side surface 112, a second side surface 113, a third side surface 114 and a fourth side
`
`surface 115. The first side surface 112 and the second side surface 113 are opposite to each
`
`other, and the third side surface 114 and the fourth side surface 115 are opposite to each
`
`other.
`
`The frame 100 is provide with an air inlet A that allows air to enter the frame 100
`
`and an air outlet 8 that allow the air to be discharged from the frame 100. For example,
`
`when the ventilating device is set on a ceiling, the air inlet A is disposed at the first side
`
`surface 112; and the air outlet B is disposed at the second side surface 113 opposite to the
`
`first side surface 112 provided with the air inlet A.
`
`As shown in Fig. 2, the filter unit 600 has a three—dimensional rectangular shape,
`
`and is provided on an upstream side of the air blower 200. The filter unit 600 includes a
`
`filter screen 610 and a filter screen frame 620, and may purify the air sucked from the air
`
`inlet A and block the entry of dust and fine particles.
`
`Among them, the filter screen frame 620 has a three—dimensional rectangular
`
`parallelepiped shape for fixing the filter screen 610. The filter screen 610 is installed in the
`
`filter screen frame 620 and includes a filter screen achieving one or more filter effects or a
`
`plurality of filter screens each achieving one or more filter effects, Such as dust filter screen,
`
`deodorizing filter screen, or dust and deodorizing filter screen.
`
`Referring to Fig. 3, the air blower 200 includes: a motor 210, a fan 220, and a casing
`
`230, wherein after the motor 210 is energized, a rotary shaft is driven to rotate. The fan
`
`220 is connected to the rotary shaft so as to generate an air flow via the rotation of the fan
`
`220 driven by the rotary shaft of the motor 210. The fan 220 and the motor 210 are
`
`

`

`CSPT—153US
`
`PATENT
`
`12
`
`contained in the casing. The casing 230 has an air suction port and an air discharge port,
`
`and in this casing 230, a wind flow from the air suction port to the air discharge port is
`
`generated due to the rotation of the fan 220.
`
`Fig. 4 is a side sectional view of the ventilating device shown in Fig. 2. As shown in
`
`Fig. 4, in the air blower 200, the air suction port is an opening that draws the air from the
`
`frame 100 into the casing 230. The casing 230 includes a first air suction port 231 and a
`
`second air suction port 232 acting as air suction ports, and an air discharge port that allows
`
`air to be discharged from the air blower 200. Among them, the first air suction port 231 and
`
`the second air suction port 232 provided on the casing 230 are opposite to each other.
`
`Under the action of the fan 220, air enters the air blower 200 from the first air suction port
`
`231 and the second air suction port 232, and then is discharged from the air blower 200 via
`
`the air discharge port.
`
`The first air suction port 231 is located at the motor 210 side of the casing 230 and
`
`faces the top surface 111. The air is sucked into the casing 230 from the back side of the
`
`casing 230, that is, from the top surface of the casing 230. The second air suction port 232
`
`is opposed to the first air suction port 231. The air is sucked into the casing 230 from the
`
`front side of the casing 230, that is, from the bottom surface of the casing 230.
`
`In particular, it should be noted that the distance from the first air suction port 231
`
`to the top surface 111 of the frame 100 is greater than the distance from the second air
`
`suction port 232 to the bottom surface 116, which will be related to the setting position of
`
`the sensor storage unit in the present embodiment.
`
`Referring to Fig. 4 continuously, the ventilating device in this embodiment further
`
`

`

`CSPT—153US
`
`PATENT
`
`13
`
`includes a first air path 300 and a second air path 400. The first air path 300 communicates
`
`the air inlet A with the first air suction port 231, that is, after the air is introduced from the
`
`air inlet A, it flows along the air path towards the first air suction port 231. The second air
`
`path 400 communicates the air inlet A with the second air suction port 232, that is, after the
`
`air is introduced from the air inlet A, it flows along the air path towards the second air
`
`suction port 232.
`
`Referring to Figs. 2, 3 and 4, the circuit board box 700 is disposed inside the frame
`
`100 and is adjacent to the outer side of the casing 230. A control circuit board 720 is
`
`disposed therein. For example, the circuit board box 700 is disposed between the third side
`
`surface 114 of the frame and the air blower 200 or between the fourth side surface 115 of
`
`the frame and the air blower 200.
`
`When the ventilating device is activated, the air enters the frame 100 through the air
`
`inlet A, and then enters the air blower 200 through the first air suction port 231 and the
`
`second air suction port 232, respectively, and then reaches the air outlet 8 through the air
`
`discharge port 234 and is discharged from the frame 100 via the air outlet B.
`
`After the air enters the space between the air inlet A and the air blower 200 from the
`
`air inlet A, most of the air flows directly to the first air suction port 231 and the second air
`
`suction port 232. That is, most of the air flows through the space between the top surface
`
`111 and the first air suction port 231 and the space between the bottom surface 116 and
`
`the second air suction port 232, only a small amount of the air flows through the space
`
`between the third side surface 114 and the air blower 200 or the space between the fourth
`
`side surface 115 and the air blower ZOO.
`
`

`

`CSPT-153US
`
`PATENT
`
`14
`
`Therefore, the circuit board box 700 is disposed in the space between the third side
`
`surface 114 and the air blower 200, or the space between the fourth side surface 115 and
`
`the air blower 200, that is, the circuit board box 700 is disposed in a space with a small air
`
`flow. The effect of the circuit board box 700 upon the air flowing through the above space
`
`may be minimized, so that the circuit board box may be provided without affecting the air
`
`volume.
`
`Fig. 5A is a schematic structural diagram of a circuit board box in the ventilating
`
`device shown in Fig. 2. Fig. SB is a schematic view of the circuit board box shown in Fig. 5A
`
`with the cover removed and viewed from another angle.
`
`As shown in Figs. 5A, SB and Fig. 3, the circuit board box 700 is provided with an
`
`operation opening 711 and an insertion opening 712. The control circuit board 720 is
`
`provided with a terminal 721.
`
`The terminal 721 is connected to the air blower 200 through a terminal lead 722.
`
`After receiving an electrical signal, the control circuit board 720 controls the operation of the
`
`air blower 200 through the lead 722. The terminal 721 serves as a medium for connecting
`
`the lead 722 to the control circuit board 720.
`
`The operation opening 711 is provided as an opening on a position opposite to the
`
`terminal 721 so that there is enough open area for the maintenance personnel to unplug or
`
`install the lead. The operation opening 711 is provided with a cover 711’.
`
`In order to prevent dust from entering the operation opening 711, the cover 711’ is
`
`fixed to the circuit board box 700 by the screw and latch structure so as to cover the
`
`

`

`CSPT—153US
`
`PATENT
`
`15
`
`operation opening 711.
`
`The insertion opening 712 is an opening for allowing the lead 722 to be inserted into
`
`the circuit board box 700, and is disposed in form of a notch on the wall of the circuit board
`
`box 700 adjacent to the operation opening 711. After the lead is inserted into the notch, the
`
`lead 722 may be fixed on the insertion opening 712 by pressing the cover 711’ on an
`
`opened portion of the notch.
`
`The lead 722 may not only be a wire connecting the circuit board box 700 and the air
`
`blower 200, but also may be a wire that provides power for the control circuit board 720
`
`and the operation of the air blower 200.
`
`In this embodiment, In order to facilitate maintenance of the circuit board box, the
`
`operation opening 711 is provided at a position opposite to the terminal 721 provided on the
`
`control circuit board, and the lead 722 connected with the air blower can be freely attached
`
`to or detached from the control circuit board 720 through the operation opening 711.
`
`When it is necessary to remove the circuit board box 700, as long as the cover 711’
`
`covered on the operation opening 711 is opened, the terminal 721 connected with the lead
`
`will be exposed, and the maintenance personnel may remove the lead from the terminal
`
`721 through operation opening 711. In this way, the circuit board box 700 is no longer
`
`connected to the air blower 200, and the maintenance personnel may entirely remove the
`
`circuit board box 700 from the frame 100. In addition, the lead 722 may be inserted into
`
`the circuit board box 700 through the insertion opening 712 provided on the wall of the
`
`circuit board box 700, and the lead 722 may be fixed on the insertion opening 712 by
`
`pressing the cover 711’ on the opened portion of the notch, thereby facilitating assembly

`
`sensor storage unit in the ventilating device shown in Fig. 2. Fig. 68 is an enlarged view of
`
`the sensor storage unit of Fig. 6A. As shown in Figs. 6A and BB, the sensor storage unit 800
`
`is formed outside the circuit board box 700, and is integrally molded into one piece with the
`
`circuit board box 700, and houses the sensor 820 and the sensor circuit board 822 therein.
`
`The sensor storage unit is covered by a lid 815.
`
`As described above, the distance L1 from the first air suction port 231 to the top
`

`from the first air suction port 231 is less than that entering the air blower from the second
`
`air suction port 232, that is, the air volume flowing through the first air path 300 is less
`
`than the air volume flowing through the second air path 400. In addition, since the motor is
`
`disposed in the first air path 300, the resistance of the first air path 300 is relatively larger
`
`and the turbulence is relatively more. Since the air volume flowing through the second air
`
`path 400 is more and the turbulence is relatively less, the sensor storage unit is disposed in
`
`the second air path, so that the humidity and the temperature may be correctly sensed,
`
`thereby improving the accuracy of the temperature and humidity sensed by the sensor
`

`
`Fig. 7 is an internal schematic diagram of the sensor storage unit in the ventilating
`
`device shown in Fig. 2. As shown in Fig. 7, the sensor 820 is stored inside the sensor
`
`storage unit 800 and is connected with the sensor circuit board 822. The sensor 820 detects
`
`the humidity or/and the temperature of the air passing through the sensor storage unit.
`
`The lid 815 is a cover that covers the sensor 820 and the sensor circuit board 822
`
`stored in the sensor storage unit and constitutes a cap for a sensor storage unit. The sensor
`
`circuit board 822 is housed inside the sensor storage unit and controls the sensor 820.
`
`Wherein, please refer to Fig. 7, the sensor storage unit 800 includes an air entrance
`
`port 811 and an air exit port 812. The air entrance port 811 is provided on the lid 815 of the
`
`sensor storage unit, that is, on a surface of the sensor storage unit 800 facing the air inlet A,
`
`and is an opening provided for allowing the air from the frame to enter the sensor storage
`
`unit. The air exit port 812 is an opening provided on the sensor storage unit and configured
`
`to allow the air to be discharged from the sensor storage unit 800.
`
`It should be noted that the first end 813 of the sensor storage unit is disposed on the
`
`wall of the circuit board box, and the second end 814 of the sensor storage unit extends
`
`outwards from the circuit board box, and the air entrance port 811 is disposed at the second
`
`end 814. With the above structure, the air entering the frame 100 from the air inlet A flows
`
`directly to the air entrance port 811 opposite to the air inlet A. The humidity and
`
`temperature of the air entering the frame 100 may be more quickly and accurately detected
`
`by the sensor 820 provided in the sensor storage unit. In addition, the air entrance port 811
`
`is provided on the second end 814 of the sensor storage unit 800 extending outwards from
`
`

`

`CSPT—153US
`
`PATENT
`
`18
`
`the Circuit board box. In this way, the second end 814 is closer to the air blower or the air
`
`inlet side, and more air enters the sensor storage unit 800. Therefore, although the circuit
`
`board box is provided in a space with a small airflow, the sensor 820 may accurately detect
`
`the humidity and temperature of the air entering the frame 100, ensuring the accuracy of
`
`the temperature and humidity sensed by the sensor.
`
`Heretofore, the embodiments of the present disclosure have been described in detail
`
`with reference to the accompanying drawings. It should be noted that, in the accompanying
`
`drawings or the specification, implementations not shown or described are all known to
`
`those of ordinary skill in the art and are not described in detail. In addition, the
`
`above—mentioned definitions of the elements and methods are not limited to the various
`
`specific structures, shapes or modes mentioned in the embodiments, and those skilled in
`
`the art can simply modify or replace them.
`
`Based on the above description, those skilled in the art should have a clear
`
`understanding of the ventilating device of the present disclosure.
`
`In summary, the present disclosure provides a ventilating device that may use less
`
`components, facilitate assembly and disassembly of components, and improve maintenance
`
`convenience by reasonably setting the positions of the circuit board box and the sensor
`
`storage unit, and has a strong application value and a comparatively better promotion and
`
`application prospects.
`
`It should also be noted that the directional terms mentioned in the embodiments,
`
`such as “upper”, “lower”, “front”, “rear”, “left”, “right”, etc., refer only to the direction of the
`
`drawings, but do not limit the scope of protection of the present disclosure. Throughout the
`
`

`

`CSPT-153US
`
`PATENT
`
`19
`
`drawings, the same elements are denoted by the same or similar reference numerals. Since
`
`ambiguities in the understanding of the present disclosure may result, the conventional
`
`structures or constructions will be omitted.
`
`Also, the shapes and sizes of the components in the drawings do not reflect actual
`
`sizes and proportions, but merely illustrate the contents of the embodiments of the present
`
`disclosure.
`
`Moreover, the word “comprising” does not exclude the presence of elements or steps
`
`7/
`\\
`other than those listed in a claim. The word a or “an” preceding an element does not
`
`exclude the presence of a plurality of such elements.
`
`The terms such as “first”, “second”, “third”, etc. in the description and the claims
`
`used before corresponding elements do not mean that these elements have any ordinal
`
`number nor does they representing the order of one element and another element, or the
`
`order of manufacturing methods, the ordinal numbers is only used to make a clear
`
`distinction between one element with a certain name and another element with the same
`
`name.
`
`The specific embodiments described above further describe the purpose, technical
`
`solutions and beneficial effects of the present disclosure in more detail. It should be
`
`understood that the above description is only specific embodiments of the present disclosure
`
`and is not intended to limit the present disclosure. Any modification, equivalent replacement,
`
`or improvement made within the spirit and principle of the present disclosure shall fall
`
`within the protection scope of the present disclosure.
