Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of temperature measuring devices, in particular to a temperature detection device with a battery limiting structure. Background Art
[0002] Food thermometers, as a key tool for food safety, have many aliases such as core thermometers, probe thermometers and food core thermometers. In today's market, a new type of food thermometer has won wide recognition in the industry with its excellent performance. This thermometer not only reaches new heights in accuracy, durability and readability, but also its design and manufacturing strictly follow industry standards to ensure that it can meet the stringent needs of commercial and professional fields.
[0003] When it comes to the working principle of a food thermometer, the core lies in the physical changes of substances at different temperatures. For example, the thermal expansion and contraction of solids, liquids and gases, especially the change of gas pressure with temperature under constant volume conditions. In addition, the thermometer also cleverly utilizes the thermoelectric effect, that is, the property of resistance changing with temperature, and the influence of thermal radiation on temperature measurement, thereby achieving accurate measurement of food temperature.
[0004] However, in the prior art, food thermometers generally face a challenge: the battery cover is easy to fall off during use. This is because the thermometer is usually equipped with a battery cavity for installing the battery, which is sealed by the battery cover. However, in actual operation, especially in an environment exposed to grease, the oil substance often becomes an "invisible lubricant" between the battery cover and the battery cavity, causing the card connection between the two to fail. In order to solve this problem, we proposed an innovative temperature detection device design, the core of which is the introduction of a unique card structure, which significantly improves the stability between the battery cover and the battery cavity and effectively prevents the battery cover from falling off. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a temperature detection device that prevents a battery cover from falling off easily.
[0006] The technical solution of the utility model is as follows:

The first limiting portion and the second limiting portion are used to further limit the rotatable connection between the battery cover and the detection body.
[0009] In a possible implementation, a rotational connection groove is provided between the battery cover and the detection body, and the rotational connection groove is used for the locking rotational connection between the battery cover and the detection body.
[0010] In a possible implementation, a rotatable connecting ring adapted to the rotatable connecting groove is provided on the battery cover, and the rotatable connecting ring can be rotatably disposed in the rotatable connecting groove, and the rotatable connecting ring is used for the locking and rotatable connection between the battery cover and the detection body.
[0011] In a possible implementation manner, both the first limiting portion and the second limiting portion are elastic.
[0012] In a possible implementation, the first limiting portion is provided with a first sliding slope, and the second limiting portion is provided with a second sliding slope matched with the first sliding slope, and the first sliding slope and the second sliding slope are both used to reduce the friction coefficient between the first limiting portion and the second limiting portion.
[0013] In a possible implementation, the first limiting portion and the second limiting portion may be deformed when subjected to a force ≥ 0.5N.
[0014] The utility model according to the above scheme has the following beneficial effects:
[0015] 1. The first limiting part and the second limiting part are engaged in the horizontal direction, so that the battery cover plate can be prevented from being separated from the detection body due to the horizontal rotation of the battery cover plate during use, thereby improving the stability of the connection structure between the battery cover plate and the detection body. Therefore, the first limiting part and the second limiting part can effectively prevent the battery cover plate from being separated from the detection body during use, thereby improving the stability of the connection structure between the battery cover plate and the detection body by designing the anti-disassembly structure of the battery cover, thereby improving the food safety of the thermometer;
[0016] The anti-dismantling structure of the battery cover for children should be optimized and improved to ensure the safety of the thermometer.

At the same time, the rotating connecting ring is positioned by the rotating connecting groove to prevent the battery cover from sliding out of the battery cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:
[0026] See also Figure 1-5 The utility model provides a temperature detection device with a battery limiting structure, the temperature detection device includes a detection body 10 and a battery cover 20, wherein one end surface of the detection body 10 is provided with a battery cavity 11 for placing a battery, and the battery cover 20 is used to cover and seal the battery cavity 11 to prevent the internal battery from falling and reduce the direct penetration of oil, dust, etc. into the battery cavity 11 to damage the battery. In this embodiment, reference Figure 1-3A battery installation kit 30 is provided in the battery cavity 11, and the battery installation kit 30 is used to fix the battery, and the battery installation kit 30 is integrally connected with the detection body 10, wherein a rotation connection groove 31 is provided between the battery installation kit 30 and the detection body 10, and the rotation connection groove 31 is used to cooperate with the card position rotation connection between the battery cover 20 and the detection body 10, and the inner wall of the rotation connection groove 31 is raised to form a first limit portion 32. In addition, a rotation connection ring 21 adapted to the rotation connection groove 31 is provided on the battery cover 20, and the rotation connection ring 21 is rotatably arranged in the rotation connection groove 31. The rotation connection ring 21 is used for the card position rotation connection between the battery cover 20 and the detection body 10, and the battery cover 20 is rotated to drive the rotation connection ring 21 to snap into the rotation connection groove 31, so as to realize 20 is spirally and rotationally connected to the detection body 10. At the same time, the rotating connecting ring 21 is positioned by the rotating connecting groove 31 to prevent the battery cover 20 from sliding out of the battery cavity 11. In addition, the rotating connecting ring 21 is provided with a second limiting portion 22 adapted to the first limiting portion 32, and the first limiting portion 32 is positioned and abutted against the second limiting portion 22. The first limiting portion 32 is positioned and abutted against the second limiting portion 22 in the horizontal direction to prevent the battery cover 20 from rotating horizontally during use, causing the battery cover 20 to separate from the detection body 10, thereby improving the stability of the connection structure between the battery cover 20 and the detection body 10. Therefore, the structural setting of the first limiting portion 32 and the second limiting portion 22 can effectively prevent the battery cover 20 from separating from the detection body 10 during use.
[0027] In some embodiments, see Figure 3-5 The first limiting portion 32 is arranged on the lower end surface of the rotating connecting ring 21, and the second limiting portion 22 is located at the bottom of the rotating connecting groove 31, wherein the battery cover 20 is rotated clockwise to make the rotating connecting ring 21 snap into the rotating connecting groove 31. Specifically, after the battery cover 20 is snapped into the rotating connecting groove 31, the first limiting portion 32 and the second limiting portion 22 form a mutually snapping structure corresponding to each other, so that the battery cover 20 cannot be rotated counterclockwise, and then, through the structural setting of the first limiting portion 32 and the second limiting portion 22, it can be prevented that the battery cover 20 drives the rotating connecting ring 21 to rotate out of the rotating connecting groove 31, resulting in the separation of the battery cover 20 from the detection body 10 and the battery installation kit 30, thereby improving the stability of the connection structure between the battery cover 20 and the detection body 10 of the utility model. In general, by designing the anti-disassembly structure of the battery cover, the stability of the connection structure between the battery cover 20 and the detection body 10 is improved, thereby improving the food safety of the thermometer.
[0028] It should be explained that the first limiting portion 32 and the second limiting portion 22 are made of elastic material, so that the first limiting portion 32 and the second limiting portion 22 are elastic. Specifically, in the present embodiment, when the battery cover 20 rotates clockwise to drive the rotating connecting ring 21 to rotate in the rotating connecting groove 31, the first limiting portion 32 and the second limiting portion 22 abut against each other. At this time, when the clockwise rotation force of the battery cover 20 is greater than 0.5N, the first limiting portion 32 and the second limiting portion 22 abut against each other and undergo elastic deformation, and as the rotation force continues to increase, the first limiting portion 32 slides to the second limiting portion 22. The limiting portion 22 is restored, thereby forming a mutually locking structure, which prevents the rotating connecting ring 21 from rotating counterclockwise and rotating the connecting groove 31. In addition, when the battery cover 20 rotates counterclockwise, when the rotation force is greater than 0.5N and the rotation angle of the battery cover 20 is greater than 90°, the first limiting portion 32 and the second limiting portion 22 also undergo elastic deformation, so that the rotating connecting ring 21 rotates counterclockwise and separates from the rotating connecting groove 31, thereby having a certain elasticity through the first limiting portion 32 and the second limiting portion 22, so as to better lock the connection relationship between the battery cover 20 and the detection body 10.
[0029] In some embodiments, see Figure 4-5 The first limiting portion 32 is provided with a first sliding inclined surface 321, and the second limiting portion 22 is provided with a second sliding inclined surface 221 adapted to the first sliding inclined surface 321. The first sliding inclined surface 321 and the second sliding inclined surface 221 are used to reduce the friction coefficient between the first limiting portion 32 and the second limiting portion 22. Specifically, the first sliding inclined surface 321 and the second sliding inclined surface 221 are arc-shaped inclined surfaces that fit each other. When the rotating connecting ring 21 rotates clockwise, the first sliding inclined surface 321 of the first limiting portion 32 and the second sliding inclined surface 221 of the second limiting portion 22 first slide and abut against each other. Therefore, by providing a structure in which both of them have arc-shaped inclined surfaces, the friction between the first limiting portion 32 and the second limiting portion 22 can be reduced, which makes it easier for the battery cover 20 to be slidably connected to the detection body 10. At the same time, it is also easier for the battery cover 20 to be separated from the detection body 10.
[0030] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
[0031] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
