Description

Technical Field

[0001] The present invention relates to the technical field of environmental temperature and humidity monitoring, and in particular to an environmental temperature and humidity monitoring device and a temperature and humidity sensor. Background Art

[0002] Environmental temperature and humidity monitoring is the process of real-time measurement, recording and analysis of temperature and humidity in a specific space or area. It is crucial in many fields. Temperature and humidity monitoring devices are closely related to smart homes and are an important part of the smart home system. They play a key role in improving the comfort of the home environment, realizing automated control and ensuring home safety.

[0003] The Chinese patent application number 2023211330847 discloses a temperature and humidity sensor, which includes: a housing; a detection component, which is arranged in the housing; a bracket, which is arranged on the housing and switches between an expanded state and a folded state. When the bracket switches to the expanded state, the bracket is used to support and fix the housing; a magnetic member, which is arranged in the housing and is used to adsorb and fix the housing when the bracket switches to the folded state. The housing includes a front shell and a rear shell, which are detachably connected and together accommodate the detection component and the magnetic member. The detection component includes a control board, which is arranged in the housing. However, in actual use, the holes and slots used to detect gas circulation are prone to be clogged by the adhesion of more impurities after long-term use, resulting in poor air circulation between the inside and outside of the housing, affecting the reliability of detection.

[0004] In addition, since the monitoring device itself will generate some heat when it is working, if this heat is transmitted to the detection module, it will cause a large error in the detection result. In addition, when the air flow circulates in the shell, fine particles will gather on the detection module, accelerating the corrosion and aging of the detection module.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-8 The present invention provides an environmental temperature and humidity monitoring device and a temperature and humidity sensor. The environmental temperature and humidity monitoring device includes a front shell 1. An upper shell 101 is provided at the top of the rear side of the front shell 1. A lower shell 102 is provided at the bottom of the rear side of the front shell 1. The upper shell 101 and the lower shell 102 are both detachably connected to the side of the front shell 1.

[0035] A display screen 103 is embedded in the front side of the front shell 1, and the display screen 103 is used to display the detected temperature and humidity. A control switch 104 is provided on the top of the front shell 1, and a control circuit board 105 is provided between the partition 106 and the display screen 103. The control circuit board 105 and the display screen 103, as well as the control circuit board 105 and the control switch 104 are electrically connected. The control switch 104 is used to control the power supply and power off of the control circuit board 105.

[0036] A temperature sensor is provided on the control circuit board 105 to monitor the temperature of the control circuit board 105 .

[0037] A partition 106 is provided inside the front shell 1, and a sealing plate 107 is provided on the side of the partition 106. The sealing plate 107 corresponds to the inner bottom of the upper shell 101, and a battery pack 109 is provided on the side of the partition 106 corresponding to the lower shell 102. The battery pack 109 is used to power the internal load components. Ventilation filter plates 110 are embedded on both sides of the upper shell 101. The upper part of the partition 106, the sealing plate 107 and the upper shell 101 together form a detection cavity. The ventilation filter plate 110 is used to filter large-volume impurities in the external air, and the ventilation filter plates 110 on both sides are used for external airflow to circulate in the detection cavity.

[0038] A heat dissipation unit 2 is provided on the partition 106, and the heat dissipation unit 2 includes an annular plate 201, a heat collecting cover 205, a heat insulating cover 207 and an air inlet groove 211. The annular plate 201 is rotatably connected to the side of the partition 106, and the annular plate 201 is located at the bottom of the sealing plate 107. A plate seat 202 is provided in the central hole of the annular plate 201, and inclined plates 203 are provided in a circular array between the side of the plate seat 202 and the inner wall of the annular plate 201. When driven by an external force, the plate seat 202 drives the heat conductive sheet 204 to rotate through the inclined plate 203. The surface of the inclined plate 203 is evenly interspersed with heat conductive sheets 204, and the heat conductive sheets 204 are used to absorb the heat generated when the control circuit board 105 is working. The heat conductive sheets 204 and the inclined plates 203 are vertically arranged. Each inclined plate 203 uses its own inclined characteristics to make the heat conductive sheet 204 in an inclined state. When the inclined plate 203 rotates, the rotation of the heat conductive sheet 204 generates a high-pressure airflow.

[0039] A driving motor 206 is disposed inside the heat collecting cover 205 . The output shaft of the driving motor 206 is fixedly connected to the plate seat 202 . The driving motor 206 provides power for the rotation of the plate seat 202 .

[0040] The heat collecting cover 205 is arranged on the side of the partition 106 close to the control circuit board 105, and the heat collecting cover 205 is arranged on the outside of the annular plate 201. The two sides of the heat collecting cover 205 are symmetrically fixedly connected with heat conducting pipes 210. The heat conducting sheet 204, the heat collecting cover 205 and the heat conducting pipes 210 are all made of high thermal conductivity materials to absorb the heat dissipated by the control circuit board 105. The air inlet groove 211 is opened on both sides of the front shell 1, and the air inlet groove 211 is located between the control circuit board 105 and the display screen 103. Filter cotton is arranged in the air inlet groove 211, and the filter cotton is used to filter impurities in the external air. After the external airflow enters the front shell 1 through the air inlet groove 211, it is collected in the heat collecting cover 205 through the heat conducting pipe 210, and enters the heat insulation cover 207 through the gap between the inclined plates 203. The heat carried in the airflow is partially absorbed after passing through the heat conducting sheet 204.

[0041] The heat insulation cover 207 is arranged on the side of the partition 106 away from the control circuit board 105 and corresponds to the annular plate 201. The heat insulation cover 207 is made of heat insulation material to prevent heat from dissipating into the detection cavity and affecting the detection accuracy. The two sides of the heat insulation cover 207 are fixedly connected with guide tubes 208. The heat insulation cover 207 and the guide tubes 208 are preferably made of heat insulation material. The ends of the guide tubes 208 on both sides are respectively connected to the ventilation grooves 209 opened on both sides of the front shell 1. The ventilation grooves 209 are vertically arrayed with guide plates. The arrangement of the guide tubes 208 and the ventilation grooves 209 on both sides forms high-speed airflow channels on both sides of the front shell 1. After the circulating airflow enters the heat insulation cover 207, the high-speed airflow in the guide tubes 208 on both sides is used to bring out the airflow in the heat insulation cover 207, and dissipate the heat to the heat conductive sheet 204, thereby finally achieving heat dissipation of the control circuit board 105.

[0042] The temperature and humidity sensor includes a temperature and humidity sensor body 108, which is arranged on a side of the partition 106 away from the control circuit board 105. An elastic pad is arranged between the temperature and humidity sensor body 108 and the partition 106. The temperature and humidity sensor body 108 is electrically connected to the control circuit board 105. By arranging the temperature and humidity sensor body 108 on the partition 106, the temperature and humidity sensor body 108 is away from the control circuit board 105, thereby reducing the interference of the heat generated by the control circuit board 105 itself on the temperature and humidity detection. The setting of the elastic pad enables the temperature and humidity sensor body 108 to have vibration conditions in the horizontal direction.

[0043] During normal operation, external airflow enters the detection cavity from the ventilation filter plate 110 on either side, passes through the position near the temperature and humidity sensor body 108, and then radiates to the outside through the ventilation filter plate 110 on the other side, thereby realizing air circulation in the detection cavity.

[0044] At the same time, the high-speed airflow flowing between the air guide pipes 208 on both sides generates a negative pressure between the control circuit board 105 and the partition 106, so that the external air enters the front shell body 1 through the air inlet groove 211, and the airflow formed by the air carries part of the heat dissipated by the control circuit board 105 and enters the heat collecting cover 205 through the heat conducting pipe 210. At the same time, the heat conducting pipe 210 and the heat collecting cover 205 absorb part of the heat dissipated by the control circuit board 105. After the airflow is gathered in the heat insulation cover 207, it is discharged into the heat insulation cover 207 through the gap between the inclined plates 203. At this time, the heat conducting plate 204 absorbs part of the heat carried in the airflow and part of the heat on the heat conducting pipe 210 and the heat collecting cover 205 through heat transfer. The hot airflow in the heat insulation cover 207 is discharged to the outside under the action of the high-speed airflow in the air guide pipe 208 to realize the heat dissipation of the control circuit board 105. At the same time, the high-speed airflow in the air guide pipe 208 dissipates the heat of the heat conducting plate 204.

[0045] In addition, when the temperature sensor detects that the temperature of the control circuit board 105 is greater than the set temperature threshold, it is determined that the control circuit board 105 is in a high temperature state. At this time, the drive motor 206 is started to drive the plate seat 202 to rotate, thereby realizing the rotation of the fan-shaped heat conducting sheet 204. Figure 7 As shown, a high-pressure airflow is generated toward the heat shield 207, and a negative pressure is generated in the heat pipe 210, so that the high temperature at the control circuit board 105 can be quickly sucked into the heat collecting cover 205 and discharged through the annular plate 201, the heat shield 207 and the air guide pipe 208, thereby realizing rapid heat dissipation of the control circuit board 105.

[0046] After long-term use, impurities carried in the external air will adhere to the filter holes of the ventilation filter plate 110, causing the ventilation filter plate 110 to be blocked, affecting the circulation of air between the detection chamber and the outside world. Therefore, the following improvements are made:

[0047] A clearing unit 3 is provided at a position corresponding to the ventilation filter plate 110 on the inner side of the upper shell 101. The clearing unit 3 includes two corresponding air guide covers 302 and an electromagnetic telescopic mechanism 308. The two air guide covers 302 are respectively provided at positions corresponding to the ventilation filter plate 110 on both sides of the inner wall of the upper shell 101. The opposite sides of the air guide covers 302 on both sides are fixedly connected to air guide covers 303. The side of the air guide cover 303 is fixedly connected to an air guide pipe 304. The air guide pipe 304 is arranged opposite to the partition plate 106. A telescopic tube 305 is provided at the end. The elastic telescopic tube 305 is made of elastic material to achieve elastic expansion and contraction. The end of the telescopic tube 305 is closed, and air holes are evenly opened on the circumferential surface of the telescopic tube 305. The airflow passes through the ventilation filter plate 110 and enters the guide cover 302, and passes through the guide cover 303, the air guide pipe 304, the telescopic tube 305 and the air holes in sequence and is discharged to the vicinity of the temperature and humidity sensor body 108, thereby shortening the time for the airflow to reach the temperature and humidity sensor body 108, reducing the change in the temperature and humidity of the airflow, and improving the detection accuracy.

[0048] The interior of the air deflector 302 is slidably matched with a slide seat 306, and a gas flow rate sensor is arranged on the side of the slide seat 306. The gas flow rate sensor is used to detect the gas flow rate passing through the ventilation filter plate 110. A transmission rod 307 is arranged on the side of the slide seat 306. The transmission rod 307 slides through the end face of the air deflector 302 and the transmission rod 307 and the end face clearance of the air deflector 302 are matched. The output end of the electromagnetic telescopic mechanism 308 is fixedly connected to the outer end of the transmission rod 307. The electromagnetic telescopic mechanism 308 is arranged on the side of the partition 106. The extension of the electromagnetic telescopic mechanism 308 drives the slide seat 306 to slide through the transmission rod 307, so that the slide seat 306 slides to between the air deflector 303 and the ventilation filter plate 110, and then drives the slide seat 306 to move quickly toward the ventilation filter plate 110, and uses the instantaneous high pressure generated to discharge the impurities blocked in the filter holes of the ventilation filter plate 110 to achieve clearing.

[0049] When in use, when the gas flow rate sensor detects that the gas flow rate at the ventilation filter plate 110 is less than the set gas flow rate threshold, it is actively determined that the ventilation filter plate 110 is blocked. At this time, the electromagnetic telescopic mechanism 308 is first started to extend, so that the slide seat 306 slides to the position between the drainage cover 303 and the ventilation filter plate 110, and then the electromagnetic telescopic mechanism 308 is quickly extended to make the slide seat 306 move toward the ventilation filter plate 110 at a high speed, thereby generating a high-pressure airflow in a short time, so that the high-pressure airflow quickly passes through the filter holes on the ventilation filter plate 110, and the ventilation filter plate 110 is cleared.

[0050] Furthermore, a sealing plug 301 corresponding to the filter hole on the ventilation filter plate 110 is provided on one side of the sliding seat 306 .

[0051] In the process of using the electromagnetic telescopic mechanism 308 to quickly extend and clear the blockage of the ventilation filter plate 110, by increasing the extension length of the electromagnetic telescopic mechanism 308, the electromagnetic telescopic mechanism 308 drives the slide 306 to move through the transmission rod 307 until the slide 306 and the ventilation filter plate 110 are in contact. At this time, the sealing plug 301 just corresponds to the filter holes on the ventilation filter plate 110. Under the driving action of the high-pressure airflow and the sealing plug 301, the impurities tightly attached to the filter holes of the ventilation filter plate 110 are pushed out, thereby achieving thorough cleaning of the impurities in the filter holes of the ventilation filter plate 110.

[0052] In addition, when the temperature or (and) humidity in the environment exceeds the detection range of the temperature and humidity sensor body 108 itself, it will cause damage to the temperature and humidity sensor body 108 and shorten its service life. Therefore, when the temperature and humidity sensor body 108 detects that the temperature or (and) humidity of the air entering the detection cavity exceeds its own detection threshold, the electromagnetic telescopic mechanism 308 is quickly extended so that the slide seat 306 fits the ventilation filter plate 110, and the sealing plug 301 is interlaced with the filter holes on the ventilation filter plate 110 to achieve sealing of the ventilation filter plate 110, prevent more high temperature or (and) high humidity air from entering, and actively protect the temperature and humidity sensor body 108.

[0053] In addition, after long-term use, fine impurity particles in the air will adhere to the temperature and humidity sensor body 108, which will accelerate the corrosion of the temperature and humidity sensor body 108, so the following improvements are made:

[0054] It also includes an air duct 4, one end of which is fixedly connected to the heat pipe 210, and the other end of the air duct 4 passes through the side of the partition 106 and is located above the sealing plate 107. The setting of the air duct 4 makes the heat pipe 210 connected to the detection cavity.

[0055] The top of the end surface of the air duct 4 close to the upper shell 101 is rotatably connected with a sealing cover 401 through a pin shaft. A driving part 402 is provided on the side of the air duct 4. The output shaft of the driving part 402 is fixedly connected to the end of the pin shaft. The driving part 402 is preferably a micro motor, which is used to drive the top of the sealing cover 401 to rotate through the pin shaft to realize the opening and closing control of the end of the air duct 4.

[0056] During use, in order to prevent the temperature and humidity sensor body 108 from being attached with a lot of fine dust and impurities after long-term use, regular self-cleaning is performed through program settings. During self-cleaning, the electromagnetic telescopic mechanism 308 is first started to drive the slide 306 to extend, so that the slide 306 moves to the position between the deflection cover 303 and the ventilation filter plate 110. Secondly, the electromagnetic telescopic mechanism 308 is quickly contracted to drive the slide 306 to move quickly to one side of the electromagnetic telescopic mechanism 308, and the side of the slide 306 is made to fit the inner end surface of the deflection cover 302. At this time, the high-pressure airflow generated passes through the deflection cover 303 and the air guide pipe 304 and enters the telescopic tube 305. Since the end of the telescopic tube 305 is closed, the instantaneous high-pressure airflow will push the telescopic tube 305 to elastically extend, so that the end of the telescopic tube 305 slightly collides with the side of the temperature and humidity sensor body 108. Under the action of the elastic pad, the temperature and humidity sensor body 108 is slightly vibrated, and then the electromagnetic telescopic mechanism 308 is extended. After the slide seat 306 passes through the drainage cover 303, negative pressure is generated in the drainage cover 303, and the telescopic tube 305 contracts, so as to circulate and shake off the fine dust impurities attached to the side of the temperature and humidity sensor body 108. At the same time, the driving part 402 is started to drive the sealing cover 401 to flip through the pin shaft to realize the opening of the end of the air duct 4, and the driving motor 206 is started to drive the plate seat 202 to rotate, so as to generate an airflow toward the heat insulation cover 207, so that the heat pipe 210 is in a negative pressure state, and the detection chamber is in a negative pressure state through the air duct 4, and the fine dust impurity particles shaken off can be sucked into the heat pipe 210 through the air duct 4, and are successively discharged to the outside through the heat collecting cover 205, the annular plate 201, the heat insulation cover 207, the drainage pipe 208, and the ventilation groove 209, so that the fine dust shaken off can be discharged by cooperating with the heat dissipation unit 2 while the temperature and humidity sensor body 108 is vibrated and cleaned, so as to prevent it from accumulating in the detection chamber.

[0057] It should be noted that when the slide 306 moves to fit the inner end surface of the air guide cover 302, the air guide cover 303 and the ventilation filter plate 110 are in a connected state, so that negative pressure can be generated in the detection cavity to suck the shaken dust and impurities into the air duct 4.

[0058] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
