Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to a high-precision temperature and humidity sensor. Background Technology

[0002] A temperature and humidity sensor is an electronic device used to measure ambient temperature and humidity. It converts ambient temperature and humidity information into electrical signals, which are then processed and transmitted using relevant circuits and chips. A temperature and humidity sensor typically consists of a sensing element, a conversion circuit, and a signal output section. The sensing element can sensitively detect changes in temperature and humidity. For example, a thermistor can be used to detect temperature, while a humidity-sensitive capacitor or a humidity-sensitive resistor can be used to detect humidity. The conversion circuit converts the changes in physical quantities acquired by the sensing element into changes in electrical signals. After processing, the signal output section outputs the measurement results in the form of digital signals (such as I2C, SPI, and other communication protocols) or analog signals (such as voltage and current). Temperature and humidity sensors are widely used in many fields, such as in smart homes for automatically adjusting indoor temperature and humidity, in agricultural production for monitoring greenhouse environments, in industrial production for controlling production environment conditions, and in meteorological observation, providing people with accurate temperature and humidity data to achieve optimized environmental control and related decision-making.

[0003] Currently, although existing high-precision outdoor temperature and humidity sensors can be suspended and their angle adjusted via a positioning plate, many problems arise with the ventilation openings after long-term use. Over time, a large amount of dust accumulates on the ventilation openings, which obstructs airflow and affects the detection results. In addition, mosquitoes and insects can easily clog the ventilation openings and even enter the sensor box, causing damage to the circuit board. Regularly cleaning the ventilation openings outdoors is not only troublesome and laborious but also consumes a lot of time and energy. This problem urgently needs to be effectively solved.

[0004] Chinese patent CN117109656A discloses an outdoor high-precision temperature and humidity sensor, which includes a sensor housing with an installation groove inside. A first motor drives a turntable to rotate, causing a first toothed block on the turntable to rotate. The first toothed block alternately contacts a second toothed block on the inner wall of both sides of a movable frame, thereby pushing the movable frame to move up and down. The movable frame then pushes a lifting rod to move, which in turn moves a ventilated net on the mounting plate up and down, facilitating the removal of impurities and dust from the ventilated net. At the same time, a second motor drives a cam plate to rotate, and the cam plate intermittently pushes the mounting plate, causing the mounting plate to vibrate back and forth through a spring, accelerating the removal of impurities and dust from the ventilated net. This effectively solves the problem of time-consuming and laborious outdoor cleaning of ventilated nets by workers, greatly improving the cleaning efficiency of the ventilated net, enabling the temperature and humidity sensor to work more efficiently, and improving the accuracy of the temperature and humidity sensor.

[0005] However, despite the use of dustproof nets to assist in dust prevention during the use of the aforementioned device, certain defects still exist in its practical application. Firstly, the surface of the dustproof net is easily clogged by dust or insects during use, which affects the airflow inside the temperature and humidity sensor, thereby reducing the efficiency of the sensor's contact with air. Over time, as dust continues to accumulate, the sensor's ventilation openings will obviously become blocked. As the usage time increases, its detection end will not be able to efficiently communicate with the outside air, which will obviously lead to a decrease in the detection accuracy of the temperature and humidity sensor. Therefore, it is necessary to improve and perfect the existing technical solution. Utility Model Content

A dustproof mechanism is fixedly installed on the back of the mounting frame, and the cleaning end of the dustproof mechanism is fitted and connected to the bottom of the dustproof mesh.

[0008] The dustproof mechanism includes a slide groove and a drive motor. The slide groove is located at the lower back of the mounting frame. A lead screw is rotatably connected inside the slide groove. The two ends of the lead screw have opposite threads. Both ends of the lead screw are threadedly connected to sliders. A brush assembly is fixedly installed on the side of the slider near the sensor body. The top of the brush assembly is fitted and connected to the bottom of the dustproof mesh. The drive motor is fixedly installed at the rear end of one side of the mounting frame. The output end of the drive motor is fixedly connected to one end of the lead screw.

[0009] Furthermore, the brush assembly includes a mounting bracket, which is fixedly installed on the inner side of the slider near the mounting frame. The top of the mounting bracket is fixedly connected with telescopic springs at equal intervals, and the top of the telescopic springs is fixedly installed with a brush plate. The top of the brush plate and the bottom of the dustproof mesh are fitted together.

[0010] Furthermore, support shafts are fixedly installed at both ends of the bottom of the brush plate, and the bottom of the support shafts passes through the mounting bracket.

[0011] Furthermore, the mounting mechanism includes a slot and a side rail frame. The slot is located at the lower ends of both sides of the temperature and humidity sensor body. The side rail frame is fixedly installed at the lower ends of both sides of the mounting frame. Limiting springs are fixedly connected to both ends of the side rail frame. A limiting frame is fixedly installed at the outer end of the limiting spring. The outer end of the limiting frame passes through the mounting frame and is inserted into the inner side of the slot.

[0012] Furthermore, the mounting mechanism also includes a sliding groove and a linkage plate. The sliding groove is located in the middle of both sides of the mounting frame. A movable block is slidably connected to the inner side of the sliding groove. A linkage frame is fixedly installed on the outer side of the movable block. The linkage plate is fixedly installed between the inner sides of the limiting frame. The overall cross-sectional shape of the linkage frame is a right-angled triangle. The inclined surface of the linkage frame is in close contact with the inner side of the linkage plate.

[0013] Furthermore, a pusher is fixedly installed on the top of the linkage frame, and the pusher has a U-shaped configuration when viewed from above.

[0014] Furthermore, support plates are fixedly installed at both ends of the back of the mounting frame, and a reinforcing shaft is fixedly installed on the top of the support plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Firstly, this utility model features a locking mechanism. During use, the mounting frame is first installed using bolts and mounting holes on the mounting plate. Then, the temperature and humidity sensor body is inserted, and the limit spring drives the limit bracket to insert into the slot to complete the locking, ensuring stable installation of the sensor body. If maintenance or disassembly is required, pressing the button plate causes the pusher to move down and push the linkage bracket to open the linkage plate, causing the limit bracket to move outward and separate from the slot, allowing for quick removal of the sensor body and facilitating maintenance.

[0019] Secondly, in this utility model, by setting a dustproof mechanism, the dustproof mesh can filter the detection vent during use, preventing dust from entering the sensor body. When there is a lot of dust, it can be cleaned regularly. The drive motor is started to drive the lead screw to rotate, and the drive slider slides in the slide groove, which drives the scraping component to move, so that the brush plate fits against the dustproof mesh to remove dust, avoid clogging, maintain high ventilation, and improve detection accuracy. The telescopic spring on the inner side of the brush plate can make it fit against the bottom of the dustproof mesh, and the support shaft and scraper can support and reinforce the brush plate, making cleaning stable and convenient.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-8 In this embodiment of the present invention, a high-precision temperature and humidity sensor includes a mounting frame 1, a humidity sensor body inserted into the inner side of the mounting frame 1, a detection vent 3 opened at the bottom of the humidity sensor body, the detection vent 3 being connected to the detection end inside the humidity sensor body, a clamping mechanism 5 fixedly mounted on the outer side of the mounting frame 1, the humidity sensor body being mounted on the inner side of the mounting frame 1 through the clamping mechanism 5, a dustproof mesh 4 fixedly mounted inside the mounting frame 1, the dustproof mesh 4 covering the bottom input end of the detection vent 3, a dustproof mechanism 6 fixedly mounted on the back of the mounting frame 1, the cleaning end of the dustproof mechanism 6 being fitted and connected to the bottom of the dustproof mesh 4;

[0031] The dustproof mechanism 6 includes a slide 61 and a drive motor 62. The slide 61 is located at the lower back of the mounting frame 1. A lead screw 63 is rotatably connected inside the slide 61. The two ends of the lead screw 63 have opposite threads. Both ends of the lead screw 63 are threadedly connected to sliders 64. A brush assembly 65 is fixedly installed on the side of the slider 64 near the sensor body. The top of the brush assembly 65 is fitted to the bottom of the dustproof mesh 4. The drive motor 62 is fixedly installed on the rear side of the mounting frame 1. The output end of the drive motor 62 is fixedly connected to one end of the lead screw 63. A humidity sensor can be inserted into the inside of the mounting frame 1. The sensor body is stably installed via the clamping mechanism 5, facilitating disassembly and maintenance. The detection vent 3 is connected to the detection end inside the sensor body, and its bottom input end is covered by the dustproof mesh 4 inside the mounting frame 1, effectively preventing dust from entering. In the dustproof mechanism 6 on the back of the mounting frame 1, the drive motor 62 drives the lead screw 63 to rotate, causing the lead screw 63 with opposite threads at both ends to drive the slider 64, which in turn drives the brush assembly 65 to adhere to the bottom of the dustproof mesh 4 to remove dust, avoid clogging, maintain high ventilation, and improve detection accuracy. The design of the sliders 64 at both ends of the lead screw 63 makes cleaning more comprehensive and efficient.

[0032] Please see Figure 7The brush assembly 65 includes a mounting bracket 651, which is fixedly installed on the inner side of the slider 64 near the mounting frame 1. Telescopic springs 652 are fixedly connected at equal intervals to the top of the mounting bracket 651. A brush plate 653 is fixedly installed on the top of the telescopic springs 652. The top of the brush plate 653 is in close contact with the bottom of the dustproof mesh 4. The mounting bracket 651, fixed inside the slider 64, provides stable support for the telescopic springs 652 and the brush plate 653. The equally spaced telescopic springs 652 allow the brush plate 653 to flexibly contact the bottom of the dustproof mesh 4, adapting to different surface conditions and ensuring close contact for effective dust removal. The close contact between the brush plate 653 and the bottom of the dustproof mesh 4 ensures comprehensive and thorough dust removal, keeping the dustproof mesh 4 clean, thereby guaranteeing normal ventilation and detection accuracy of the temperature and humidity sensor.

[0033] Please see Figure 7 Both ends of the bottom of the brush plate 653 are fixedly installed with support shafts 654. The bottom of the support shafts 654 passes through the mounting bracket 651. The support shafts 654 can provide stable support and guidance for the brush plate 653, making the brush plate 653 more stable when performing brushing action, avoiding shaking or deviation, thereby ensuring the stability and accuracy of the brush plate 653 and the bottom of the dustproof mesh 4, and improving the cleaning effect and efficiency.

[0034] Please see Figures 3-6 The mounting mechanism 5 includes a slot 51 and a side rail bracket 52. The slot 51 is located at the lower ends of both sides of the temperature and humidity sensor body 2. The side rail bracket 52 is fixedly installed at the lower ends of both sides of the mounting frame 1. Limiting springs 53 are fixedly connected to both ends of the side rail bracket 52. Limiting brackets 54 are fixedly installed at the outer ends of the limiting springs 53. The outer ends of the limiting brackets 54 penetrate the mounting frame 1 and are inserted into the inner side of the slot 51. By opening slots 51 at the lower ends of both sides of the temperature and humidity sensor body 2 and fixing side rail brackets 52 at the lower ends of both sides of the mounting frame 1, the limiting springs 53 at both ends of the side rail bracket 52 provide elastic support for the limiting brackets 54, so that the outer ends of the limiting brackets 54 can penetrate the mounting frame 1 and be inserted into the inner side of the slot 51. This achieves a stable mounting of the temperature and humidity sensor body 2 in the mounting frame 1. This mounting method is simple and effective, ensuring the firmness of the installation and facilitating disassembly and assembly, making it convenient for sensor maintenance and replacement.

[0035] Please see Figures 3-6The mounting mechanism 5 also includes a sliding groove 55 and a linkage plate 56. The sliding groove 55 is located in the middle of both sides of the mounting frame 1. A movable block 57 is slidably connected to the inner side of the sliding groove 55. A linkage frame 58 is fixedly installed on the outer side of the movable block 57. The linkage plate 56 is fixedly installed between the inner sides of the limiting frame 54. The overall cross-sectional shape of the linkage frame 58 is a right-angled triangle. The inclined surface of the linkage frame 58 is in close contact with the inner side of the linkage plate 56. The sliding groove 55 located in the middle of both sides of the mounting frame 1 serves as the movable block 57. A sliding track is provided, and the linkage frame 58 on the outside of the movable block 57 and the linkage plate 56 on the inside of the limit frame 54 cooperate with each other. The overall cross-section of the linkage frame 58 is a right triangle, and its inclined surface is in close contact with the inside of the linkage plate 56. This design allows the linkage frame 58 to move by sliding the movable block 57 during operation, and the linkage plate 56 to be pushed by the inclined surface of the linkage frame 58, thereby controlling the limit frame 54 and achieving the purpose of quickly assembling and disassembling the temperature and humidity sensor body 2. The operation is convenient and the structure is stable.

[0036] Please see Figures 5-6 A pusher 59 is fixedly installed on the top of the linkage frame 58. The pusher 59 has a U-shaped top view. By setting the pusher 59, the two linkage frames 58 can be moved simultaneously by pushing the pusher 59 during use, which facilitates quick disassembly and assembly of the temperature and humidity sensor body 2.

[0037] Please see Figures 5-6 Support plates 510 are fixedly installed at both ends of the back of the mounting frame 1. A reinforcing shaft 511 is fixedly installed on the top of the support plate 510. The top of the reinforcing shaft 511 passes through the push frame 59. The push frame 59 is slidably connected to the outside of the reinforcing shaft 511. The top of the reinforcing shaft 511 passes through the push frame 59, and the push frame 59 is slidably connected to the outside of the reinforcing shaft 511. The advantage of this design is that it can provide stable guidance and limit for the movement of the push frame 59, ensuring that the push frame 59 maintains linear movement during sliding operation without deviation or shaking, thereby enhancing the stability and reliability of the entire device during operation.

[0038] Please see Figures 1-4 The mounting frame 1 has fixed brackets 7 at both ends of the top rear side, and mounting plates 8 are fixedly installed on the back of the fixed brackets 7. Mounting holes 9 are opened at both ends of the mounting plates 8. The fixed brackets 7 at both ends of the top rear side of the mounting frame 1 provide stable support for the mounting plates 8. The mounting holes 9 at both ends of the mounting plates 8 make it easy to fix the entire device in the required position by bolts and other connecting parts, which enhances the convenience and flexibility of installation and ensures the stability and reliability of the device during use.

[0039] Please see Figures 1-4The push frame 59 has a pressing plate 512 fixedly installed in the middle. Wear-resistant pads are fixedly connected to the inner walls of the slide groove 61 and the side rail frame 52. Wear-resistant pads are also fixedly connected to the outer surfaces of the movable block 57 and the limit frame 54 located inside the side rail frame 52. The pressing plate 512 fixedly installed in the middle of the push frame 59 makes it convenient for users to press the push frame 59, making the disassembly and assembly process more convenient. Wear-resistant pads are fixedly connected to the inner walls of the slide groove 61 and the side rail frame 52, as well as the outer surfaces of the movable block 57 and the limit frame 54 located inside the side rail frame 52. This design can effectively reduce friction and wear between components and extend the service life of the equipment.

[0040] The working principle of this utility model is as follows: By setting the clamping mechanism 5, during use, the mounting frame 1 can be installed in the desired position by bolts through the mounting holes 9 on the mounting plate 8. Then, the temperature and humidity sensor body 2 is inserted into the inner side of the mounting frame 1. At this time, the limit spring 53 extends and retracts to reset, which drives the limit frame 54 to move inward and insert into the inner side of the slot 51. The limit frame 54 and the slot 51 interlock and limit each other, which helps to clamp and install the temperature and humidity sensor body 2, so that the temperature and humidity sensor body 2 can be stably installed in the inner side of the mounting frame 1. If it is necessary to disassemble and repair the temperature and humidity sensor body 2, the press plate 512 can be pressed to move the sensor body 2 into the mounting frame 1. 512 drives the pusher 59 to move down, which in turn pushes the movable block 57 and the linkage frame 58 to move down. The linkage frame 58 moves down and comes into contact with the linkage plate 56. The inclined surface of the linkage frame 58 contacts the linkage plate 56, which in turn opens the linkage plate 56. The linkage plate 56 moves outward, which causes the limit spring 53 to be in an extended state. At this time, the limit frame 54 moves outward simultaneously. The limit frame 54 can be pulled out from the inside of the slot 51. The limit frame 54 and the slot 51 separate from each other. At this time, the temperature and humidity sensor body 2 and the mounting frame 1 bracket lose their limit, making it convenient and quick to remove the temperature and humidity sensor body 2 from the inside of the mounting frame 1. This makes the whole device easy to quickly inspect and maintain the temperature and humidity sensor.

[0041] By setting up a dustproof mechanism 6, the device can filter the detection vent 3 through the dustproof mesh 4 during use, preventing dust from entering the interior of the temperature and humidity sensor body 2 through the detection vent 3. During this process, the dust is blocked by the dustproof mesh and adheres to the outer surface of the dustproof mesh. When there is a lot of dust, it can be cleaned periodically. In the specific cleaning process, the drive motor 62 is started, which drives the lead screw 63 to rotate. The lead screw 63 rotates inside the slide groove 61, which in turn drives the slider 64 to slide inside the slide groove 61. The linear sliding of the slider 64 drives the scraping component to reciprocate. The slider 64 drives the mounting bracket 651 to move, which in turn drives the brush plate at the end of the telescopic spring 652. The brush plate 653 is attached to the dustproof mesh 4 at one point. Through linear displacement, the dust on the outer surface of the dustproof mesh 4 can be removed, preventing dust blockage. This keeps the temperature and humidity sensor body 2 in a highly ventilated state for a long time, improving the detection accuracy of the device during use. During use, the inner side of the brush plate 653 is equipped with a telescopic spring 652. During cleaning, the telescopic spring 652 drives the brush plate 653 to adhere to the bottom of the dustproof mesh 4, improving the overall cleaning efficiency of the device. Furthermore, the coordinated design of the support shaft 654 and the sunspot during cleaning supports and reinforces the brush plate 653, making the brush plate 653 more stable in brushing the dustproof mesh 4, resulting in a more stable and convenient cleaning process.
