[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] A rapid temperature sensing panel with an annular groove in this embodiment, such as Figures 1-7 As shown, it includes a panel 1, a thermal conductive cap 2, a metal shell 3 and a temperature sensing element 4. The top surface of the panel 1 is provided with a plurality of annular grooves 11 and through holes 12 corresponding to the annular grooves 11. The through holes 12 are located in the area surrounded by the annular grooves 11; the thermal conductive cap 2 includes a cap body 21 and a support portion 22. The interior of the cap body 21 has a cavity 211, and the top and bottom of the cavity 211 have openings. The thermal conductive cap 2 is installed in the annular groove 11; the support portion 22 is provided at the top outer edge of the cap body 21, and the bottom surface of the support portion 22 is supported on the panel 1; the metal shell 3 is wrapped around the top of the thermal conductive cap 2 and closes the top opening of the cavity 211; the space between the thermal conductive cap 2 and the annular groove 11 is filled with temperature-resistant glue 5; the temperature sensing element 4 is respectively fixed in the through holes 12, and the top of the temperature sensing element 4 is against the metal shell 3.

[0030] The top of the cavity 211 has an opening. As one embodiment, a through hole is opened on the top wall of the cavity 211 to form an opening at the top of the cavity 211. Figure 1 and Figures 4-6As another embodiment, the cavity 211 is a structure penetrating from top to bottom, as shown in Figure 2 and 3 After the temperature guide cap 2 is installed to the annular hole, the opening at the top of the cavity 211 is opposite to the penetrating hole 12, and the top of the temperature guide cap 2 is wrapped by the metal shell 3, that is, the temperature sensing element 4 arranged in the penetrating hole can be shielded, and the temperature sensing element 4 is protected from being exposed to the outside. When the cooking container is placed on the panel 1, the cooking container and the temperature sensing element 4 are only separated by the metal shell 3, so that the temperature sensing element 4 can be closer to the cooking container, and the metal shell 3 has good heat conduction effect, so that the temperature of the cooking container can be quickly transmitted to the temperature sensing element 4, so that the temperature sensing element 4 can more accurately and sensitively detect the real-time temperature of the cooking container. The temperature guide cap 2 and the metal shell 3 can be made of the same or different materials, and the temperature guide cap 2 has more space in the selection of materials, which is conducive to optimizing the processing technology and reducing the material cost.

[0031] The bottom of the cap body 21 is inserted into the annular groove 11, and the temperature-resistant glue 5 is filled between the temperature guide cap 2 and the annular groove 11, so that the temperature guide cap 2 is fixed to the annular groove 11, and the temperature guide cap 2 is prevented from falling off the panel 1 during use. The annular groove 11 can limit the side wall of the cap body 21 to prevent the temperature guide cap 2 from moving. In addition, since the annular groove 11 is provided and the temperature-resistant glue 5 is filled between the annular groove 11 and the temperature guide cap 2, the soup from the top surface of the panel 1 seeps into the upper part of the penetrating hole 12 and needs to enter the annular groove 11, then bypasses the inner wall of the temperature guide cap 2, and then passes through the top surface of the support table to reach the penetrating hole 12. Therefore, the external soup needs to pass through a long path to seep into the penetrating hole 12, and the temperature-resistant glue 5 is also filled in the annular groove 11, so it is extremely difficult for the external soup to seep into the penetrating hole 12, thereby having excellent waterproof performance.

[0032] The metal shell 3 can be made of metal materials such as stainless steel, aluminum alloy or copper alloy, which not only has high heat conduction efficiency, but also has high strength, good ductility and wear resistance. Therefore, the metal shell 3 only needs to be set to a thin thickness to protect the temperature sensing element 4, and is not easy to be worn due to the impact and friction of the pot during long-term use, and can have a longer service life.

[0033] Further, the four peripheral edges of the metal shell 3 are inwardly bent and buckled on the bottom surface of the support portion 22.

[0034] The metal shell 3 can be punched from a metal sheet, and wrapped on the top of the support portion 22 by punching, so that the four peripheral edges of the metal shell 3 are inwardly bent and buckled on the bottom surface of the support portion 22, which can effectively prevent the metal shell 3 from falling off the temperature guide cap 2.

[0035] Further, the inner wall of the metal shell 3 is close to the temperature-conducting cap 2.

[0036] By such arrangement, the bottom surface of the metal shell 3 can be supported by the temperature-conducting cap 2, and the metal shell 3 is not easy to deform when a relatively heavy cooking container is placed on the metal shell 3.

[0037] Further, the cavity 211 and the through hole 12 are both filled with temperature-resistant glue 5, and the temperature-sensing element 4 is fixed to the temperature-conducting cap 2 by the temperature-resistant glue 5.

[0038] The temperature-resistant glue 5 filled in the cavity 211 and the through hole 12 can fix the temperature-sensing element 4, so that the temperature-sensing element 4 can be fixed relative to the metal shell 3 after assembly and will not move during use, so as to ensure the temperature measuring effect. In addition, the temperature-resistant glue 5 can also expel the air between the temperature-sensing element 4 and the metal shell 3, so as to avoid affecting the temperature transmission efficiency due to the air between the temperature-sensing element 4 and the metal shell 3. It should be noted that the temperature-resistant glue 5 refers to glue that can meet the use environment of the rapid temperature-sensing panel 1, such as silicone glue, ceramic glue, etc., and the composition of the temperature-resistant glue 5 is not specifically limited.

[0039] Further, the panel 1 is also provided with a corresponding sunken groove 13, the annular groove 11 and the through hole 12 are both arranged in the sunken groove 13, the temperature-conducting cap 2 is installed in the sunken groove 13, and the top surface of the temperature-conducting cap 2 is not lower than the top surface of the panel 1.

[0040] By arranging the sunken groove 13 on the panel 1, the temperature-conducting cap 2 can be embedded in the sunken groove 13 for installation. The sunken groove 13 can be an annular groove structure (as shown in Figure 3 ) or a circular groove structure (as shown in Figure 4 and Figure 5 ).

[0041] In order to enable the temperature-sensing element 4 to accurately detect the temperature of the cooking container, the metal shell 3 needs to be in contact with the cooking container. To this end, after the temperature-conducting cap 2 is installed on the panel 1, the top of the metal shell 3 is not lower than the top surface of the panel 1, that is, the metal shell 3 protrudes from the panel 1 (as shown in Figure 3 and Figure 4 ) or the top surface of the metal shell 3 is flush with the panel 1 (as shown in Figure 5As one of the embodiments, the temperature guide cap 2 and the metal shell 3 are both protruded from the panel 1, so that the cooking container placed on the panel 1 will not shake, and a plurality of temperature guide caps 2, such as three, four, five or more, can be arranged on the panel 1, so that the cooking container placed on the panel 1 can be supported by the plurality of temperature guide caps 2 at the same time, which not only makes the cooking container placed on the panel 1 more stable, but also makes the temperature of the cooking container more accurately detected by the multi-point temperature measurement. As another embodiment, the top surface of the temperature guide cap 2 is flush with the panel 1, and at least one temperature guide cap 2 is arranged, of course, in order to better detect the temperature of each part of the bottom surface of the cooking container, the number of temperature guide caps 2 can also be increased accordingly, and more accurate temperature data can be obtained by multi-point temperature measurement.

[0042] Further, the top surface of the metal shell 3 is downwardly inclined around the periphery, so that the edge of the top surface of the metal shell 3 is connected to the edge of the sink 13 of the panel 1.

[0043] By such an arrangement, the top surface of the metal shell 3 and the panel 1 can be smoothly transitioned, and when the panel 1 is splashed with liquid at the temperature guide cap 2, it can be easily cleaned.

[0044] In the description of the present specification, the description of the terms "one embodiment", "certain embodiments", "illustrative embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily mean the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] The technical principle of the present application is described above in combination with specific embodiments. These descriptions are only for the purpose of explaining the principle of the present application, and cannot be interpreted as limiting the scope of protection of the present application in any way. Based on the explanation here, those skilled in the art can think of other specific embodiments of the present application without creative labor, and these equivalent variations or replacements are all included in the scope defined by the claims of the present application.
