[0032] The technical solutions of the present application will be further illustrated below with reference to the drawings and through specific embodiments.

[0033] One embodiment of the temperature-sensing panel 1 with an annular groove 11 is assembled as shown in the figure, comprising: Figures 1-5

[0034] A panel 1, the top surface of which is provided with a plurality of annular grooves 11, and a support platform 12 is formed in the area surrounded by the annular grooves 11, and the support platform 12 is provided with a through hole 13 that penetrates from top to bottom;

[0035] A temperature guide cap 2 is installed in the annular groove 11, and the top surface of the temperature guide cap 2 is not lower than the top surface of the panel 1, and the temperature guide cap 2 comprises a cap body 21 and a connecting portion 22, the bottom of the temperature guide cap 2 has an opening, the side wall of the temperature guide cap 2 matches the annular groove 11, the connecting portion 22 is provided in the temperature guide cap 2 and has a tubular structure with an open bottom, and the connecting portion 22 is inserted into the through hole 13;

[0036] A connecting buckle 3 is installed on the bottom surface of the panel 1, and the connecting buckle 3 comprises a buckle body 31 and a limiting portion 32, the buckle body 31 is a tubular structure with openings at both ends, and the limiting portion 32 is provided on the outer wall of the buckle body 31; the upper end of the buckle body 31 is inserted into the through hole 13, and the lower end of the connecting portion 22 is inserted into each other and buckled and fixed;

[0037] A temperature-sensing element 4 is provided in the connecting portion 22, and the temperature-sensing element 4 abuts against the top wall of the connecting portion 22, and the connecting portion 22 is filled with temperature-resistant glue 5.

[0038] ​The temperature guide cap 2 is fixed to the upper surface of the panel 1 through the annular groove 11 and the through hole 13, and the connecting buckle 3 is inserted into the through hole 13 from the bottom surface of the panel 1 to be buckled with the temperature guide cap 2, so that the temperature guide cap 2 is fixed to the panel 1 in the horizontal direction. The inner top surface of the cap body 21 and the top surface of the limiting portion 32 clamp the panel 1 to fix the temperature guide cap 2 to the panel 1 in the vertical direction. The support platform 12 provides support for the cap body 21. As one of the embodiments, the support platform 12 is flush with the panel 1, as shown in Figure 1 . As another embodiment, the support platform 12 is lower than the panel 1, as shown in Figures 2-4 .

[0039] Before installation, the temperature sensing element 4 is placed in the connecting portion 22, and the temperature-resistant glue 5 is filled into the connecting portion 22 to fix the temperature sensing element 4. The temperature-resistant glue 5 refers to glue that can meet the temperature requirements in actual application, such as silicone glue. Filling the temperature-resistant glue 5 into the connecting portion 22 not only fixes the temperature sensing element 4, but also expels air in the connecting portion 22, so that the heat conduction effect between the temperature sensing element 4 and the temperature guide cap 2 is better, and the temperature of the cooking container can be more accurately and sensitively detected. The temperature sensing element 4 abuts against the top of the connecting portion 22, so that the temperature sensing element 4 can be closer to the cooking container to further improve the accuracy and sensitivity of temperature detection. As one of the embodiments, the temperature guide cap 2 can be made of metal materials such as aluminum, stainless steel, and copper, which have good heat conduction performance and are wear-resistant. Of course, the temperature guide cap 2 can also be made of engineering plastics such as PEEK plastic.

[0040] In order to accurately detect the temperature of the cooking container, the temperature guide cap 2 needs to be in contact with the cooking container. To achieve this purpose, after the temperature guide cap 2 is installed to the panel 1, the top of the temperature guide cap 2 is not lower than the top surface of the panel 1, that is, the temperature guide cap 2 protrudes from the panel 1 or the top surface of the temperature guide cap 2 is flush with the panel 1. As one of the embodiments, the temperature guide cap 2 protrudes from the panel 1. In order to prevent the cooking container from shaking when placed on the panel 1, a plurality of temperature guide caps 2, such as three, four, five, or more, can be arranged on the panel 1. When the cooking container is placed on the panel 1, it can be supported by multiple temperature guide caps 2 at the same time, which not only makes the cooking container more stable when placed on the panel 1, but also makes the temperature of the cooking container more accurately detected through multi-point temperature measurement.

[0041] The utility model discloses a connecting buckle 3 can make the temperature -sensing cap 2 through the mechanism structure fixed on the panel 1, thereby better prevent the temperature -sensing cap 2 from falling off the panel 1, compared with the temperature -sensing cap 2 with the way of glue bonding on the panel 1, the utility model discloses the mechanical connection mode reliability is better, and the product is more stable and durable, as one of the implementation mode, the temperature -sensing element 4 can be thermistor, in order to make the temperature -sensing element 4 with the electrical element (such as circuit board) below the panel 1 connect, therefore the buckle body portion 31 is set to the tubular structure of both ends opening, to make the connecting wire of temperature -sensing element 4 can from the inside of buckle body portion 31 downward and with the electrical element below the panel 1 electrically connected.

[0042] As a connecting mode of temperature -sensing cap 2 and connecting buckle 3, the inner wall of connecting portion 22 is provided with a clamping groove 221, the outer wall of buckle body portion 31 is provided with a protruding buckle 311, the upper end of buckle body portion 31 is inserted into connecting portion 22, so that the buckle 311 and the clamping groove 221 are buckled.

[0043] In the embodiment, the inner wall of connecting portion 22 cooperates with the outer wall of buckle body portion 31, so that buckle body portion 31 can be inserted into connecting portion 22, and the buckle 311 on the outer wall of buckle body portion 31 is buckled with the clamping groove 221 on the inner wall of connecting portion 22, it should be pointed out that, since connecting portion 22 and buckle body portion 31 are both tubular structures, the thickness of their side walls is small, therefore, when buckle body portion 31 is inserted into connecting portion 22, both connecting portion 22 and buckle body portion 31 can be elastically deformed to a certain extent, so that even if the outer wall of buckle body portion 31 is provided with a protruding buckle 311, it can also be inserted into connecting portion 22 to realize the connection of buckle 311.

[0044] Further, the inner wall of connecting portion 22 is provided with a first guide inclined surface 222 at the lower end, and the outer wall of buckle body portion 31 is provided with a second guide inclined surface 312 at the top; the clamping groove 221 is a reverse tooth structure.

[0045] By setting the first guide inclined surface 222 and the second guide inclined surface 312, the connecting portion 22 and the buckle body portion 31 can be guided when they are inserted, so that the buckle body portion 31 can be better inserted into the connecting portion 22; the clamping groove 221 is set to a reverse tooth structure, so that the connecting portion 22 and the buckle body portion 31 are not easy to come loose after being inserted and buckled, and the problem of the temperature -sensing cap 2 falling off can be better avoided.

[0046] Further, the outer wall of buckle body portion 31 or the inner wall of connecting portion 22 is provided with a step 313, which is used to limit the depth of the insertion of buckle body portion 31 into connecting portion 22.

[0047] Since the temperature sensing element 4 is arranged in the connecting portion 22, and the temperature sensing element 4 is relatively fragile, if the depth of the buckle body portion 31 inserted into the connecting portion 22 is too large, the buckle body portion 31 is easy to crush the temperature sensing element 4, in order to avoid the problem, the utility model sets up the step 313 on the outer wall of the buckle body portion 31 or the inner wall of the connecting portion 22, the depth of the buckle body portion 31 inserted into the connecting portion 22 can be limited by the limiting action of the step 313, thereby effectively preventing the temperature sensing element 4 from being crushed, and the depth of the buckle body portion 31 inserted into the connecting portion 22 can also limit the distance between the bottom surface of the cap body portion 21 and the top surface of the limiting portion 32, preventing the temperature guide cap 2 and the connecting buckle 3 from crushing the panel 1 during installation.

[0048] As another connecting mode of the temperature guide cap 2 and the connecting buckle 3, the inner wall of the buckle body portion 31 is provided with a clamping groove 221, the outer wall of the connecting portion 22 is provided with a protruding clamping buckle 311, and the lower end of the connecting portion 22 is inserted into the buckle body portion 31, so that the clamping buckle 311 and the clamping groove 221 are buckled.

[0049] As another embodiment, the connecting portion 22 can also be inserted into the buckle body portion 31, in which the outer wall of the connecting portion 22 cooperates with the inner wall of the buckle body portion 31, so that the connecting portion 22 can be inserted into the buckle body portion 31 to realize the buckling fixation of the clamping buckle 311 and the clamping groove 221.

[0050] Further, the outer wall of the connecting portion 22 is provided with a first guide inclined surface 222, and the inner wall of the buckle body portion 31 is provided with a second guide inclined surface 312, and the clamping groove 221 is a reverse tooth structure.

[0051] By arranging the first guide inclined surface 222 and the second guide inclined surface 312, the connecting portion 22 and the buckle body portion 31 can be guided when being inserted, so that the buckle body portion 31 can be better inserted into the connecting portion 22, and the clamping groove 221 is arranged as a reverse tooth structure, so that the connecting portion 22 and the buckle body portion 31 are not easy to be loosened after being inserted and buckled, and the problem of the temperature guide cap 2 falling off can be better avoided.

[0052] Further, the outer wall of the connecting portion 22 is provided with a step 313, and the step 313 is used for limiting the depth of the connecting portion 22 inserted into the buckle body portion 31.

[0053] In this embodiment, limiting the depth of the connecting portion 22 inserted into the buckle body portion 31 can limit the distance between the inner top surface of the cap body portion 21 and the top surface of the limiting portion 32, preventing the temperature guide cap 2 and the connecting buckle 3 from crushing the panel 1 during installation.

[0054] Preferably, an elastic sealing pad 6 is further included, which is sleeved on the connecting portion 22 and located between the cap portion 21 and the support table 12, or the elastic sealing pad 6 is sleeved on the buckle portion 31 and located between the upper surface of the limiting portion 32 and the bottom surface of the panel 1.

[0055] The elastic sealing pad 6 can play a buffering role, so that the temperature guide cap 2 and the connecting buckle 3 can prevent the panel 1 from being broken due to a relatively large impact force on the panel 1 at the moment of buckling when being assembled to the panel 1; of course, the elastic sealing pad 6 can also play a role of absorbing processing errors, so that the temperature guide cap 2 and the connecting buckle 3 are not prone to shaking after being assembled to the panel 1, and the elastic sealing pad 6 can also play a waterproof role to prevent soup on the panel 1 from flowing to the lower side of the panel 1 along the gap between the temperature guide cap 2, the connecting buckle 3 and the panel 1.

[0056] Preferably, the inner top wall of the connecting portion 22 is at least partially in a thin-walled structure 223, and the temperature sensing element 4 abuts against the thin-walled structure 223.

[0057] The inner top wall of the connecting portion 22 is at least partially in a thin-walled structure 223, and the temperature sensing element 4 abuts against the thin-walled structure 223, so that the temperature sensing element 4 can be further close to the cooking container under the premise of ensuring that the temperature guide cap 2 has good strength, and the accuracy and sensitivity of temperature detection are further improved.
