Description

Technical Field

[0001] This utility model relates to the field of household temperature and humidity instruments, specifically a household temperature and humidity sensor. Background Technology

[0002] A household temperature and humidity sensor is a device used to monitor the temperature and humidity in a home environment. Its temperature measurement principle includes the resistance principle, which utilizes the characteristic that the resistance of a metal or semiconductor material changes with temperature. Its humidity measurement principle usually consists of two parallel electrodes and a humidity-sensitive medium in the middle. When the ambient humidity changes, the dielectric constant of the humidity-sensitive medium changes, resulting in a change in the capacitance value.

[0003] Existing household temperature and humidity sensors have the following problems in use: they are usually fixed structures, and they are usually designed with a one-piece molded structure. The width of the base structure is usually limited. When the base structure is placed without being fixed by the fixing components, it cannot provide good lateral support for the whole. When subjected to side impact, it is very easy to tip over. At the same time, after long-term use, the electronic sensor may experience accuracy drift, resulting in inaccurate measurement results. It is impossible to know whether accuracy drift has occurred. Moreover, due to the one-piece molded structure, it is not easy to disassemble and maintain. Utility Model Content

[0004] (a) Technical problems to be solved.

[0005] To address the shortcomings of existing technologies, this invention provides a household temperature and humidity sensor, solving the problems mentioned in the background section.

[0006] (ii) Technical solution.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a household temperature and humidity sensor, including a support mechanism, a temperature and humidity detection mechanism at the front end of the support mechanism, a base, and two L-shaped grooves symmetrically formed at the top of the base. A support seat is slidably connected to the inner side wall of each of the two L-shaped grooves at opposite ends. Each of the two support seats is fixedly connected to the inner side wall of its corresponding L-shaped groove by a damping telescopic rod at opposite ends. The support seats are made of PVC anti-slip material, and a notch is formed in the middle of the lower part of the opposite ends of the two support seats.

[0008] As a further embodiment of this utility model: a damping block is fixedly connected to the upper center of the front end of the base, and a cross positioning block is fixedly connected to the center of the front side wall of the damping block. The temperature and humidity detection mechanism includes a card holder that slides and fits the damping block and the cross positioning block on the outside. Two card slots are symmetrically opened on the front side of the top of the card holder. A card seat is slidably engaged in the card slot. An electronic temperature and humidity detector is fixedly connected to the front end of one card seat, and a mechanical temperature and humidity instrument is fixedly connected to the front end of the other card seat.

[0009] As a further improvement of this utility model: a damping groove with a damping block sliding connection is provided in the middle of the rear end of the card holder, and a cross positioning groove matching the cross positioning block is provided at the center of the front end of the inner side wall of the damping groove.

[0010] As a further improvement of this utility model: the electronic temperature and humidity detector has a built-in rechargeable lithium battery, and the bottom of the electronic temperature and humidity detector is provided with a charging interface. The base is an L-shaped base, and a reinforcing protrusion is provided on each side of the bend at the front end of the base. An installation groove is provided at the middle of the front side of the top of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, a hidden lateral support structure is provided at both ends of the base. That is, when the base structure is placed but not fixed by the fixing components, the lateral support seat can be pulled out from both ends of the base. It is made of non-slip material, which can increase the width of the bottom support structure and improve its lateral support capacity. It is not easy to tip over when subjected to side impact.

[0013] 2. In this utility model, a mechanical temperature and humidity meter is set in conjunction with an electronic temperature and humidity detector. The temperature and humidity data of the two can corroborate each other to determine whether the household temperature and humidity sensor is working properly. At the same time, the overall household temperature and humidity sensor adopts a temperature and humidity detection structure that facilitates disassembly and assembly. Both the electronic temperature and humidity detector and the mechanical temperature and humidity meter are connected to the card holder through a card slot, and the card holder is also connected to the front end of the base, so the whole can be easily disassembled and maintained.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-5In this embodiment of the utility model, a household temperature and humidity sensor includes a support mechanism 1. A temperature and humidity detection mechanism 2 is provided at the front end of the support mechanism 1. The support mechanism 1 includes a base 11. Two L-shaped grooves 13 are symmetrically opened at the top of the base 11. A support seat 14 is slidably connected to the inner side wall of the two L-shaped grooves 13 at opposite ends. The two support seats 14 are fixedly connected to the inner side wall of the corresponding L-shaped groove 13 at opposite ends by a damping telescopic rod 15. The support seats 14 are made of PVC anti-slip material, and a notch is opened in the middle of the lower part of the two support seats 14 at opposite ends. The whole is provided with a hidden lateral support structure at both ends of the base 11. That is, when the base 11 structure is only placed and not fixed by the fixing components, the lateral support seats 14 can be pulled out from both ends of the base 11. The anti-slip material can increase the width of the bottom support structure and improve its lateral support capacity, making it less likely to tip over when subjected to side impact.

[0024] A damping block 16 is fixedly connected to the upper center of the front end of the base 11. A cross-shaped positioning block 17 is fixedly connected to the center of the front side wall of the damping block 16. The temperature and humidity detection mechanism 2 includes a card holder 21 that slides and fits the damping block 16 and the cross-shaped positioning block 17 on the outside. Two card slots 22 are symmetrically opened on the front side of the top of the card holder 21. A card seat 23 is slidably engaged in the card slot 22. An electronic temperature and humidity detector 24 is fixedly connected to the front end of one card seat 23, and a mechanical temperature and humidity meter 25 is fixedly connected to the front end of the other card seat 23. The whole system is equipped with a mechanical temperature and humidity meter 25 in conjunction with the electronic temperature and humidity detector 24. The temperature and humidity data of the two can corroborate each other to determine whether the household temperature and humidity sensor is working properly.

[0025] The rear center of the card holder 21 has a damping groove 26 that is slidably connected to the damping block 16. The front center of the inner side wall of the damping groove 26 has a cross positioning groove 27 that matches the cross positioning block 17. The overall household temperature and humidity sensor adopts a temperature and humidity detection structure that is easy to disassemble and assemble. The electronic temperature and humidity detector 24 and the mechanical temperature and humidity meter 25 are both attached to the corresponding slots 22 of the card holder 21 through the card seat 23. The card holder 21 is also attached to the outside of the damping block 16 and the cross positioning block 17 at the front end of the base 11. The whole system can be easily disassembled and maintained.

[0026] The electronic temperature and humidity detector 24 has a built-in rechargeable lithium battery and a charging interface at the bottom, which can be connected to a charging device to charge the electronic temperature and humidity detector 24. The base 11 is an L-shaped base, and a reinforcing protrusion is provided on both sides of the bend at the front end of the base 11 to strengthen the structure of the base 11. A mounting groove 12 is provided at the middle of the front side of the top of the base 11. The base 11 can be fixedly installed at the corresponding installation position by using the mounting groove 12 with the mounting components, or it can be placed directly by the base 11.

[0027] The working principle of this utility model is as follows: The base 11 can be fixedly installed at the corresponding installation position through its mounting slot 12 with the installation components, or it can be placed directly on the base 11. The entire structure has a hidden lateral support structure at both ends of the base 11. That is, when the base 11 structure is only placed and not fixed by the fixing components, the lateral support seats 14 can be pulled out from both ends of the base 11. They are made of non-slip material, which can increase the width of the bottom support structure and improve its lateral support capacity. It is not easy to tip over when subjected to side impact. The entire structure is equipped with a mechanical temperature and humidity meter in conjunction with the electronic temperature and humidity detector 24. Table 25 shows that both can perform temperature and humidity detection and present the temperature and humidity data. The temperature and humidity data of the two can corroborate each other to determine whether the household temperature and humidity sensor is working properly. In addition, the overall household temperature and humidity sensor adopts a temperature and humidity detection structure that facilitates disassembly and assembly. The electronic temperature and humidity detector 24 and the mechanical temperature and humidity meter 25 are both connected to the corresponding slots 22 of the card holder 21 through the card holder 23. The card holder 21 is also connected to the outside of the damping block 16 and the cross positioning block 17 at the front end of the base 11, which allows for convenient disassembly and maintenance.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
