Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to an adhesive temperature sensor. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core component of a temperature measuring instrument.

[0003] For example, CN221859752U discloses an adhesive temperature sensor, which includes a housing, an antenna, a circuit board, a bottom shell, adhesive, and a temperature probe. The bottom of the housing is connected to the bottom of the bottom shell, forming an internal space. The antenna and the circuit board are located in the internal space. The antenna and the circuit board are electrically connected. The bottom shell is provided with a temperature measuring groove for placing the temperature probe, and the temperature probe is located in the temperature measuring groove.

[0004] In the existing technology, the adhesive layer of adhesive sensors is mostly integral or rigidly connected, which has good adaptability to smooth curved surfaces. However, when there are uneven surfaces such as bumps and arcs on the surface of the object being measured, the adhesive layer is difficult to adapt to the deformation of the surface shape, and local curling and gaps are likely to occur. This results in the sensor not adhering tightly to the surface being measured, which in turn affects the temperature measurement accuracy or the stability of the adhesion. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the adhesive layer of existing adhesive sensors is mostly integral or rigidly connected, which makes it difficult to adapt to the surface shape and deform, and is prone to local peeling and gaps, affecting the temperature measurement accuracy or adhesion stability. Therefore, this invention proposes an adhesive temperature sensor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adhesive temperature sensor, comprising a sensor assembly, the sensor assembly comprising a housing and a connecting housing, one side of the housing being mounted on one side of the connecting housing, and an adhesive mechanism being mounted on the other side of the connecting housing, the adhesive mechanism comprising a flexible heat insulation pad, a cavity being formed on one side of the flexible heat insulation pad, a first elastic memory plate being fixedly connected inside the cavity, a second elastic memory plate being fixedly connected to one side of the first elastic memory plate, one side of the flexible heat insulation pad being fixedly connected to the other side of the connecting housing, and adhesive being fixedly connected to the other side of the flexible heat insulation pad, with grooves formed between the multiple adhesives.

[0007] Preferably, a protective film is adhered to one side of the adhesive, and a tear-off label is fixedly attached to both ends of the protective film.

[0008] Preferably, a circuit board is mounted on one side of the connecting shell.

[0009] Preferably, the connecting shell has an opening in the middle, and a temperature probe is installed inside the opening. One end of the temperature probe is electrically connected to the circuit board.

[0010] Preferably, a temperature measuring mechanism is installed on the outside of the temperature probe. The temperature measuring mechanism includes a fixed plate, which is fixedly connected to the inside of the opening. A movable rod is slidably connected to one side of the fixed plate.

[0011] Preferably, one end of the moving rod is fixedly connected to a socket plate, and the middle part of the socket plate is fixedly connected to the outside of the temperature probe.

[0012] Preferably, a compression spring is sleeved on the outside of the moving rod, and the compression spring is disposed between the fixed plate and the sleeve plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, after tearing off the protective film, the adhesive is pasted onto the surface of the temperature measuring object. When the surface of the temperature measuring object is uneven, it can push the local adhesive to deform, causing the flexible heat insulation pad to deform. The first and second elastic memory plates, which are perpendicular to each other, can deform to adapt to the deformation at different locations. The groove can reduce the interference between the adhesives. The multiple adhesives can adjust their positions independently, improving the overall deformation adaptability and avoiding adhesive failure due to mutual squeezing or pulling. This makes it easier for the adhesive to stick to different surfaces and improves the tightness of the adhesion.

[0015] 2. In this utility model, when the temperature measuring probe is measuring the temperature, the temperature measuring probe contacts the temperature measuring point, pushing the temperature measuring probe to move. The sleeve plate and the moving rod move, and the compression spring deforms. The elastic force of the compression spring pushes the sleeve plate and the temperature measuring probe to move, so that the temperature measuring probe always keeps in contact with the temperature measuring point, thereby improving the stability of the detection results.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides an adhesive temperature sensor, including a sensor assembly 1. The sensor assembly 1 includes a housing 11 and a connecting housing 12. One side of the housing 11 is mounted on one side of the connecting housing 12, and an adhesive mechanism 2 is mounted on the other side of the connecting housing 12. The adhesive mechanism 2 includes a flexible heat insulation pad 27. A cavity 24 is formed on one side of the flexible heat insulation pad 27. A first elastic memory board 25 is fixedly connected inside the cavity 24. A second elastic memory board 26 is fixedly connected to one side of the first elastic memory board 25. One side of the flexible heat insulation pad 27 is fixedly connected to the other side of the connecting housing 12. An adhesive 23 is fixedly connected to the other side of the flexible heat insulation pad 27. A groove 28 is formed between multiple adhesives 23. A protective film 21 is adhered to one side of the adhesive 23. Both ends of the protective film 21 are fixedly connected to tear-off labels 22. A circuit board 14 is mounted on one side of the connecting housing 12. An opening 15 is formed in the middle of the connecting housing 12. A temperature probe 13 is disposed inside the opening 15. One end of the temperature probe 13 is electrically connected to the circuit board 14.

[0024] When installing the temperature sensor, the protective film 21 is torn off. Protruding tear-off tags 22 are provided at both ends of the protective film 21, allowing for easy and quick tearing from one side of the adhesive 23. The adhesive 23 is then applied to the surface of the object being measured. When the surface is uneven, the adhesive 23 deforms locally, causing the flexible heat insulation pad 27 to deform. The first elastic memory plate 25 and the second elastic memory plate 26, which are perpendicular to each other, can deform to adapt to different deformations. Multiple adhesive 23s adhere to the surface during deformation. The grooves 28 between the adhesives 23 reduce interference between them. The positions of the multiple adhesives 23 can be adjusted independently, improving the overall deformation adaptability and avoiding adhesion failure due to mutual squeezing or pulling. This makes it easier for the adhesives 23 to be pasted on different surfaces and improves the tightness of the adhesion. Through the combination of the flexible heat insulation pad 27, the first elastic memory plate 25 and the second elastic memory plate 26, the deformation capability of the flexible heat insulation pad 27 is used to ensure the adhesion. At the same time, the support of the two sets of elastic memory plates maintains the stability of the heat insulation structure and protects the sensor from high temperature damage.

[0025] Example 2: Figures 1-4 As shown, a temperature measuring mechanism 3 is installed on the outside of the temperature probe 13. The temperature measuring mechanism 3 includes a fixed plate 31, which is fixedly connected to the inside of the opening 15. A moving rod 34 is slidably connected to one side of the fixed plate 31. A sleeve plate 33 is fixedly connected to one end of the moving rod 34. The middle part of the sleeve plate 33 is fixedly connected to the outside of the temperature probe 13. A compression spring 32 is sleeved on the outside of the moving rod 34. The compression spring 32 is disposed between the fixed plate 31 and the sleeve plate 33.

[0026] When the temperature measuring probe 13 measures the temperature, it contacts the temperature measuring point, pushing the temperature measuring probe 13 to move. The sleeve plate 33 and the moving rod 34 move, and the moving rod 34 slides inside the fixed plate 31. The fixed moving rod 34 makes linear motion, and the compression spring 32 deforms. The elastic force of the compression spring 32 pushes the sleeve plate 33 and the temperature measuring probe 13 to move, so that the temperature measuring probe 13 always keeps in contact with the temperature measuring point, improving the stability of the detection results.

[0027] The usage and working principle of this device are as follows: When installing a temperature sensor, the protective film 21 is torn off, and the adhesive 23 is pasted onto the surface of the object being measured. When the surface of the object being measured is uneven, the adhesive 23 can be pushed to deform locally, causing the flexible heat insulation pad 27 to deform. The first elastic memory plate 25 and the second elastic memory plate 26, which are perpendicular to each other, can deform to adapt to the deformation at different locations. When multiple adhesives 23 deform, the grooves 28 between the adhesives 23 reduce the interference between them. The multiple adhesives 23 can adjust their positions independently, improving the overall deformation adaptability. Temperature is measured through the temperature probe 13. When the temperature probe 13 contacts the temperature measurement point, it is pushed to move. The sleeve plate 33 and the moving rod 34 move, and the compression spring 32 deforms. The elastic force of the compression spring 32 pushes the sleeve plate 33 and the temperature probe 13 to move, so that the temperature probe 13 always remains in contact with the temperature measurement point.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
