Description

Technical Field

[0001] The invention relates to the technical field of temperature sensors, in particular to a high-precision temperature and humidity sensor. Background Art

[0002] A temperature and humidity sensor is an electronic device used to measure ambient temperature and humidity. It can convert the temperature and humidity information in the environment into electrical signals, and process and transmit them with the help of related circuits and chips. The temperature and humidity sensor is usually composed of a sensing element, a conversion circuit and a signal output part. The sensing element can sensitively sense changes in temperature and humidity, such as using a thermistor to detect temperature and using a humidity-sensitive capacitor or humidity-sensitive resistor to sense humidity. The conversion circuit converts the physical quantity changes obtained by the sensing element into changes in electrical signals. After processing, the signal output part outputs the measurement results in the form of digital signals (such as I2C, SPI and other communication protocols) or analog signals (such as voltage, current). Temperature and humidity sensors are widely used in many fields, such as in smart homes for automatic adjustment of indoor temperature and humidity, in agricultural production for monitoring greenhouse environments, in industrial production for controlling production environment conditions, and in meteorological observations, etc., to provide people with accurate temperature and humidity data to achieve environmental optimization control and related decision-making;

[0003] At present, although the existing outdoor high-precision temperature and humidity sensors can be suspended and adjusted in angle through the positioning plate, many problems will occur in the vents after long-term use. A lot of dust will adhere to the vents after long-term use, and the dust will hinder the air from entering, thus affecting the detection effect. In addition, mosquitoes can easily cause the vents to be blocked, and even enter the sensor box to cause damage to the circuit board. The staff regularly go outdoors to clean up, which is not only troublesome and laborious, but also consumes a lot of time and energy. This problem urgently needs to be effectively solved;

[0004] The Chinese patent with the publication number of "CN117109656A" discloses an outdoor high-precision temperature and humidity sensor, which includes a sensor housing, and a mounting groove is provided inside the sensor housing. The first motor drives the turntable to rotate, so that the first tooth block on the turntable rotates, and the first tooth block contacts the second tooth blocks on the inner walls of both sides of the moving frame in turn, thereby pushing the moving frame to move up and down, and the moving frame then pushes the lifting rod to move, and the lifting rod drives the air-permeable net on the mounting plate to move up and down, so that the impurities and dust on the air-permeable net can fall off. At the same time, the second motor drives the cam plate to rotate, and the cam plate intermittently pushes the mounting plate, so that the mounting plate reciprocates through the spring to accelerate the removal of impurities and dust on the air-permeable net, effectively solving the problem of time-consuming and labor-intensive outdoor cleaning of the air-permeable net by the staff, greatly improving the cleaning efficiency of the air-permeable net, enabling the temperature and humidity sensor to work more efficiently, and improving the accuracy of the temperature and humidity sensor;

[0005] However, during the use of the above-mentioned device, although a dust-proof net is used to assist in dust prevention, there are still certain defects in the specific application process. First, during use, the surface of the dust-proof net is easily blocked by dust or mosquitoes, thereby affecting the air circulation inside the temperature and humidity sensor, and then causing the efficiency of the temperature and humidity sensor contacting the air to decrease. Over time, as dust continues to adhere, it will obviously cause the ventilation holes of the sensor to be blocked. As the use time increases, its detection end cannot be efficiently connected to the outside air, which will obviously cause the detection accuracy of the temperature and humidity sensor to decrease. Therefore, it is necessary to improve and perfect the existing technical solutions. Summary of the invention

[0031] The dust-proof mechanism 6 includes a slide 61 and a drive motor 62. The slide 61 is opened at the lower end of the back of the mounting frame 1. The slide 61 is internally rotatably connected with a screw rod 63. The threads of the two ends of the screw rod 63 are rotated in opposite directions. Both ends of the screw rod 63 are threadedly connected with a slider 64. A brush assembly 65 is fixedly installed on the side of the slider 64 close to the sensor body.

The sensor body is stably installed through the clamping mechanism 5, which is convenient for disassembly and maintenance. The detection air vent 3 is connected to the detection end in the sensor body, and its bottom input end is covered by the dustproof net 4 in the mounting frame 1, which effectively blocks the entry of dust. In the dustproof mechanism 6 on the back of the mounting frame 1, the driving motor 62 drives the screw rod 63 to rotate, so that the screw rod 63 with threads at both ends rotating in opposite directions drives the slider 64, which drives the brush assembly 65 to fit the bottom of the dustproof net 4 to remove dust, avoid blockage, maintain a high ventilation state, and improve detection accuracy. The design of the sliders 64 at both ends of the screw rod 63 makes cleaning more comprehensive and efficient.

[0032] See also Figure 7The brush assembly 65 includes a mounting frame 651, which is fixedly mounted on the inner side of the slider 64 near the mounting frame 1.

[0034] See also Figure 3-Figure 6 The card-mounting mechanism 5 includes a card slot 51 and a side rail frame 52.

The outer ends of the limit frames 54 penetrate the mounting frame seat 1 and are plugged into the inner sides of the card slots 51. By providing the card slots 51 at the lower ends of both sides of the temperature and humidity sensor body 2 and fixing the side rail frames 52 at the lower ends of both sides of the mounting frame seat 1, the limit springs 53 at the inner ends of the side rail frames 52 provide elastic support for the limit frames 54, so that the outer ends of the limit frames 54 can penetrate the mounting frame seat 1 and be plugged into the inner sides of the card slots 51, thereby realizing the stable card-mounting of the temperature and humidity sensor body 2 in the mounting frame seat 1. This card-mounting method is simple and effective, which can not only ensure the firmness of the installation, but also facilitate disassembly and assembly, and facilitate the maintenance and replacement of the sensor.

[0035] See also Figure 3-Figure 6The clamping mechanism 5 also includes a sliding groove 55 and a linkage plate 56. The sliding groove 55 is opened in the middle of both sides of the mounting frame seat 1. The inner side of the sliding groove 55 is slidably connected with a movable block 57. The outer side of the movable block 57 is fixedly installed with a linkage frame 58. The linkage plate 56 is fixedly installed between the inner sides of the limit frame 54.

A sliding track is provided, and the linkage frame 58 on the outside of the movable block 57 cooperates with the linkage plate 56 on the inside of the limit frame 54. The overall cross-section of the linkage frame 58 is a right-angled triangle, and its inclined surface is fitted and connected to the inner side of the linkage plate 56. This design allows the linkage frame 58 to move through the sliding of the movable block 57 during operation, and the linkage plate 56 is pushed by the inclined surface of the linkage frame 58, thereby realizing the control of the limit frame 54, achieving the purpose of quickly disassembling and assembling the temperature and humidity sensor body 2, and the operation is convenient and the structure is stable.

[0036] See also Figure 5-Figure 6 A push frame 59 is fixedly installed on the top of the linkage frame 58. The top view of the push frame 59 is in a concave shape. By setting the push frame 59, during use, the device can simultaneously drive the two linkage frames 58 to move by pushing the push frame 59, which is convenient for quick disassembly and assembly of the temperature and humidity sensor body 2.

[0037] See also Figure 5-Figure 6 , support plates 510 are fixedly installed at both ends of the back side of the mounting frame 1, and 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, and 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 motion during the sliding operation without deviation or shaking, thereby enhancing the stability and reliability of the entire device during operation.

[0038] See also Figure 1-Figure 4 A fixing frame 7 is fixedly installed at both ends of the top rear side of the mounting frame seat 1, and a mounting plate 8 is fixedly installed on the back of the fixing frame 7. Both ends of the mounting plate 8 are provided with mounting holes 9. The fixing frames 7 fixedly installed at both ends of the top rear side of the mounting frame seat 1 provide a stable support for the mounting plate 8. The mounting holes 9 opened at both ends of the mounting plate 8 make it convenient to fix the entire device at a desired position by connecting parts such as bolts, thereby enhancing the convenience and flexibility of installation and ensuring the stability and reliability of the device during use.

[0039] See also Figure 1-Figure 4A pressing plate 512 is fixedly installed in the middle of the push frame 59, and the inner walls of the slide groove 61 and the side rail frame 52 are fixedly connected with wear-resistant gaskets, and the outer surfaces of the movable block 57 and the limit frame 54 located inside the side rail frame 52 are also fixedly connected with wear-resistant gaskets. The pressing plate 512 fixedly installed in the middle of the push frame 59 is convenient for the user to press the push frame 59, making the disassembly and assembly process more convenient, and the inner walls of the slide groove 61 and the side rail frame 52 and the outer surfaces of the movable block 57 and the limit frame 54 located inside the side rail frame 52 are fixedly connected with wear-resistant gaskets. This design can effectively reduce friction and wear between components and extend the service life of the equipment.

[0040] The working principle of the present invention is as follows: by setting a card-mounting mechanism 5, during the use of the device, the mounting frame 1 can first be installed at the desired position by bolting with the mounting holes 9 on the mounting plate 8, and then the temperature and humidity sensor body 2 can be inserted into the inner side of the mounting frame 1. At this time, the limit spring 53 can be retracted and reset to drive the limit frame 54 to move inward and insert it into the inner side of the card slot 51. The limit frame 54 and the card slot 51 are plugged and limited with each other to assist in the card-mounting installation of the temperature and humidity sensor body 2, so that the temperature and humidity sensor body 2 can be stably installed on the inner side of the mounting frame 1. If the temperature and humidity sensor body 2 needs to be disassembled and repaired, it can be disassembled and repaired by pressing the pressing plate 512. 12 drives the push frame 59 to move downward, and the push frame 59 can push the movable block 57 and the linkage frame 58 to move downward. The linkage frame 58 can move downward to resist the linkage plate 56, and the inclined surface of the linkage frame 58 contacts the linkage plate 56, so that the linkage plate 56 can be opened, and the linkage plate 56 can move outward to drive the limit spring 53 to be in an extended state. At this time, the limit frame 54 moves outward synchronously, and the limit frame 54 moves outward to be pulled out from the inner side of the slot 51, and the limit frame 54 and the slot 51 are separated from each other. At this time, the temperature and humidity sensor body 2 and the mounting frame 1 bracket lose their limit, so the temperature and humidity sensor body 2 can be easily and quickly removed from the inside of the mounting frame 1, so that the device as a whole is convenient for quickly repairing and maintaining the temperature and humidity sensor.

[0041] By setting up the dustproof mechanism 6, the device can filter the detection air vent 3 through the dustproof net 4 during use, so as to prevent dust from entering the interior of the temperature and humidity sensor body 2 through the detection air vent 3. During this period, the dust is blocked by the dustproof and adheres to the outer surface of the dustproof net. When there is a lot of dust, it can be cleaned regularly. In the specific cleaning process, the driving motor 62 can be started to run, and the driving motor 62 can be used to drive the screw rod 63 to rotate. The screw rod 63 is located on the inner side of the slide groove 61 and rotates. At this time, the slider 64 can be driven by the screw rod 63 to slide on the inner side of the slide groove 61. The linear sliding of the slider 64 can drive the reciprocating displacement of the scratching assembly. The slider 64 drives the movable displacement of the mounting frame 651 to drive the brush plate at the end of the telescopic spring 652. 653 fits the dustproof net 4, and the brush plate 653 performs linear displacement to remove the dust on the outer surface of the dustproof net 4, which can avoid dust clogging and keep the temperature and humidity sensor body 2 in a high ventilation state for a long time, which can improve the detection accuracy of the overall use of the device. In addition, during its use, since a telescopic spring 652 is provided on the inner side of the brush plate 653, during the cleaning process, the telescopic spring 652 can be used to drive the brush plate 653 to fit the bottom of the dustproof net 4, which can improve the overall cleaning efficiency of the device. In addition, during the cleaning process, the coordinated setting of the support shaft 654 and the sun spot can support and reinforce the brush plate 653, so that the brush plate 653 can brush the dustproof net 4 more stably, making the overall cleaning of the device more stable and convenient.
