[0027] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 9 As shown, this embodiment provides a food temperature probe with a stable structure, comprising: a probe housing 1, a PCB circuit board 2, an insulating tail end 3 and a tail metal piece 4, wherein the PCB circuit board 2 is arranged in the probe housing 1, and the tail metal piece 4 is connected to the probe housing 1 through the insulating tail end 3, and an extended end 201 is arranged at one end of the PCB circuit board 2 close to the tail metal piece 4, and the extended end 201 of the PCB circuit board 2 passes through the insulating tail end 3 and is connected to the tail metal piece 4.

[0029] The probe housing 1 described in this embodiment is preferably a metal housing; the insulating tail end 3 is preferably a plastic structural part, which is convenient for providing a gripping position during actual use and avoiding scalding the user; the tail metal part 4 is preferably used as a charging electrode, such as a positive electrode or a negative electrode, to cooperate with the metal housing to achieve charging when connected to an external repeater or charging device; the protruding end 201 is a protruding structure of the conductive PCB circuit board 2, and is preferably integrated with the main board part of the PCB circuit board 2; the main board part of the PCB circuit board 2 refers to the main part of the circuit board except the protruding end 201.

[0030] Preferably, in this embodiment, a first step 202 is formed between the protruding end 201 and the main board part of the PCB circuit board 2, and the first step 202 is connected to the inner wall of the insulating tail end 3, and the protruding end 201 can better pass through the insulating tail end 3 with the internal thread 301 to be connected to the tail metal part 4, and the first step 202 is connected to the inner wall of the insulating tail end 3, so that a snap-fit ​​connection structure can be formed between the inner wall of the insulating tail end 3 and the protruding end 201, that is, the first step 202 is used at the tail to limit and fix the PCB circuit board 2; the length of the protruding end 201 corresponds to the distance between the tail metal part 4 and the first step 202, that is, after assembly, the main board part of the PCB circuit board 2 is just connected to the tail metal part 4 through the protruding end 201, so as to ensure the stability and reliability of the charging structure.

[0031] Therefore, this embodiment can achieve the tail limiting and fixing function of the PCB circuit board 2 through the first step 202, and can also achieve a stable connection between the tail metal part 4 and the main board part of the PCB circuit board 2 through the protruding end 201.

[0032] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, more preferably, the main board part of the PCB circuit board 2 of this embodiment is also provided with a second step 206, and the position of the second step 206 corresponds to the position of the socket joint of the probe housing 1 and the insulating tail end 3, and the second step 206 is engaged with the probe housing 1. Since the probe housing 1 is sleeved on the inner wall of the insulating tail end 3, a third step 7 will be formed at the tail end of the probe housing 1 and the inner wall of the insulating tail end 3, that is, the third step 7 is formed at the socket joint position of the probe housing 1 and the insulating tail end 3, and the second step 206 is engaged with the third step 7, which can well realize the assembly and limiting fixing function of the PCB circuit board 2. This embodiment fully and reasonably utilizes the third step 7 at the socket joint position between the probe housing 1 and the insulating tail end 3, and sets the corresponding second step 206 on the main board part of the PCB circuit board 2, and then when assembling, it is only necessary to insert the PCB circuit board 2 into the probe housing 1 until the second step 206 and the third step 7 are in contact to play the role of clamping and limiting between the steps. The structural design of this embodiment is ingenious, the assembly process is simple and efficient, and the stability and reliability of the product structure can be further enhanced.

[0033] More preferably, the second step 206 of the present embodiment can be used as a charging electrode or an antenna carrier structure. The present embodiment can directly use the protruding end 201 and / or the tail metal part 4 as one of the charging electrodes, such as the positive electrode. At this time, since the second step 206 is engaged with the third step 7, the connection between the second step 206 and the probe housing 1 is realized. The probe housing 1 is preferably a metal housing. Therefore, the present embodiment can use the second step 206 as another charging electrode, such as a negative electrode. In addition, the second step 206 can also be used as an antenna carrier structure, that is, an antenna is provided on the second step 206 to increase the communication capability of the food temperature probe. Of course, in actual applications, in addition to the second step 206, a needle tip or other position can also be used as a charging negative electrode; the positions of the charging positive and negative electrodes can be adjusted according to actual conditions and design requirements.

[0034] like Figure 3 and Figure 4 As shown, this embodiment also preferably includes a conductive connection kit 5, and the conductive connection kit 5 is sleeved on the protruding end 201. The conductive connection kit 5 can be implemented by a metal sleeve. More preferably, the conductive connection kit 5 in this embodiment can also be implemented by a metal spring, that is, the metal spring is directly sleeved on the protruding end 201. Compared with the use of a metal sleeve, it can not only well ensure the stability of the charging structure, but also further increase its contact effectiveness through the elastic effect of the metal spring and provide a buffer protection effect.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the end of the tail metal piece 4 close to the PCB circuit board 2 is provided with an external thread 401, and the end of the insulating tail end 3 close to the tail metal piece 4 is provided with an internal thread 301, and the tail metal piece 4 is connected to the insulating tail end 3 through the internal thread 301 and the external thread 401. Preferably, as Figure 8 and Fig. 9 As shown, the length of the internal thread 301 in this embodiment is greater than the length of the external thread 401, that is, the number of thread turns of the internal thread 301 is greater than the number of thread turns of the external thread 401, thereby, on the one hand, ensuring that the tail metal part 4 is completely screwed in and not easy to loosen; on the other hand, the internal thread 301 can also be used to cooperate with the protruding end 201 and the first step 202 to achieve a limiting and fixing effect on the PCB circuit board 2.

[0036] like Figures 1 to 4 As shown, this embodiment also preferably includes a sealing ring 6, which is arranged between the insulating tail end 3 and the tail metal part 4 to increase the sealing and waterproof effect of the product.

[0037] like Figure 5 As shown, the main board portion of the PCB circuit board 2 in this embodiment preferably includes an antenna area 203, a reserved area 204 and a component placement area 205 which are connected in sequence, the antenna area 203 is arranged at one end of the PCB circuit board 2 close to the protruding end 201, and the component placement area 205 is arranged at one end of the PCB circuit board 2 close to the needle tip of the probe housing 1. In this embodiment, the antenna 207 is preferably arranged in the antenna area 203, so as to achieve a better antenna effect through the insulating tail end 3; the reserved area 204 refers to the area between the antenna area 203 and the component placement area 205, which can be used as a functional reservation, such as adding an onboard antenna. The component layout area 205 refers to an area for setting temperature detection chips, main control chips and other electronic components. The battery 208 is arranged at the end of the component layout area 205 close to the needle tip. The component layout area 205 is arranged at the end of the PCB circuit board 2 close to the needle tip of the probe housing 1. This is mainly because during actual use, this area will be inserted into food. Since there is moisture in the food, the problem of overtemperature can be effectively avoided, thereby well ensuring the service life of the electronic components.

[0038] Therefore, correspondingly, Figures 1 to 3 As shown, in this embodiment, an indicator mark 101 is provided on the probe housing 1, and the position of the indicator mark 101 corresponds to the connection position between the reserved area 204 and the component arrangement area 205, so that the user can intuitively judge the insertion depth of the food temperature probe during actual use.

[0039] To sum up, this embodiment can make the product assembly process simpler and more efficient through optimized structural design, can effectively improve the reliability and stability of the product charging structure, improve the product assembly efficiency, and can provide a better foundation for improving the product's service life and user experience.
