[0031] Refer to Figure 1, a thermal induction structure, comprising: a base 100, a top plate 700, a temperature sensor 300, and a protective cover 500; the top plate 700 is disposed on the base 100, and the top plate 700 is used to support cookware; the top plate 700 is provided with a mounting hole 750; the temperature sensor 300 is installed between the top plate 700 and the base 100, and the temperature sensor 300 can sense the temperature at the top plate 700 or inside the base 100; the protective cover 500 is installed in the mounting hole 750, the protective cover 500 covers the top of the temperature sensor 300 and can relatively isolate between the temperature sensor 300 and the outside of the top plate 700; wherein, the top of the protective cover 500 is flush with the top of the top plate 700. When the cookware is placed on the top plate 700, the base 100 can heat and cook the cookware and the ingredients inside it through the eddy current effect of the electromagnetic coil. During this process, the temperature sensor 300 can detect the temperature of the cookware or the top plate 700 in real time, so as to timely understand the specific temperature situation during cooking, and thus facilitate the cooking process. The protective cover 500 can not only provide direct and effective protection for the temperature sensor 300, and because the top of the protective cover 500 is flush with the top of the top plate 700, the two can jointly bear the collision force caused by the placement of the cookware. Moreover, the flushness of the protective cover 500 and the top plate 700 also makes it difficult to form a secondary collision effect between the top plate 700 and the protective cover 500 when the cookware is placed, thereby avoiding the collision and damage of the top plate 700 to the protective cover 500 and the temperature sensor 300. In addition, the flushness of the protective cover 500 and the top plate 700 can also make the cookware obtain a more stable supporting effect when placed on the top plate 700, thereby ensuring that the cooking operation can be carried out more stably and reliably.

[0032] In some embodiments, referring to Figure 2 , the protective cover 500 is nested in the mounting hole 750, and the protective cover 500 and the mounting hole 750 are fixed to each other. The nested installation and mutual fixation effect between the protective cover 500 and the mounting hole 750 can effectively avoid the problem of mutual shaking between the protective cover 500 and the mounting hole 750 when the top plate 700 receives a collision or impact. Therefore, the installation stability of the protective cover 500 and the temperature sensor 300 in the mounting hole 750 can be effectively improved, and further the damage of the temperature sensor 300 caused by collision or impact can be avoided.

[0033] It can be envisaged that the protective cover 500 can also be movably installed in the mounting hole 750, such as by installing a shock-absorbing structure such as a spring, so that the protective cover 500 can remain movable and reduce the impact force when it is impacted. Therefore, the specific implementation manner is not unique, but can be adjusted accordingly according to the actual situation, and is not limited here.

[0034] In some embodiments, referring to Figure 2, an adhesive is filled between the protective cover 500 and the mounting hole 750, and the protective cover 500 and the mounting hole 750 are adhesively connected. The adhesive can not only effectively fix and connect between the protective cover 500 and the mounting hole 750, but also has the characteristic of strong fluidity. Therefore, it can smoothly fill and seal the gap between the protective cover 500 and the mounting hole 750, and then effectively achieve the fixing effect between the protective cover 500 and the mounting hole 750.

[0035] It can be anticipated that the protective cover 500 and the mounting hole 750 can also be fixed in other ways, such as directly installing and fixing them by interference fit. Therefore, the specific implementation method is not unique, but can be adjusted accordingly according to the actual situation, and no limitation is made here.

[0036] In some embodiments, referring to Figure 3 , the protective cover 500 includes a filling portion 530 and a clamping portion 550. The filling portion 530 extends into the mounting hole 750 and is relatively fixed to the mounting hole 750. The clamping portion 550 is located below the mounting hole 750; there is a step between the clamping portion 550 and the filling portion 530 and it abuts against the bottom edge of the mounting hole 750 through the step. The filling portion 530 can fill the gap between the temperature sensor 300 and the mounting hole 750, so that the two are isolated from each other, and cooperate with the adhesive to achieve the effect of preventing substances on the placing top plate 700 from flowing in. The clamping portion 550 can position and fix the height direction of the filling portion 530 by abutting against the bottom edge of the mounting hole 750, and then ensure that the top of the protective cover 500 can be accurately flush with the top of the top plate 700.

[0037] In some embodiments, referring to Figure 3 , an insulating layer is provided between the temperature sensor 300 and the protective cover 500. The insulating layer can not only effectively prevent components such as cookware and the top plate 700 from damaging the temperature sensor 300 when exposed to external current, but also effectively slow down or isolate various electromagnetic effects from interfering with the temperature sensor 300, and then ensure that the temperature sensor 300 can stably perform temperature detection work.

[0038] Specifically, the insulating layer can be an insulating sleeve sleeved on the outer periphery of the temperature sensor 300, or it can also be components such as a coating or a shell with insulating effects. The specific implementation method is not unique, but can be adjusted accordingly according to the actual situation, and no limitation is made here.

[0039] In some embodiments, referring to Figure 3, a protective cover 800 is provided on the outer periphery of the temperature sensor 300, and the protective cover 800 is used to fix the temperature sensor 300 in the base 100. The protective cover 800 can not only effectively protect the temperature sensor 300, but also stably install the temperature sensor 300 in the base 100, thus avoiding problems such as shaking between the temperature sensor 300 and the base 100.

[0040] In some embodiments, referring to Figure 3 , the temperature sensor 300 is provided with a positioning flange 350, and the positioning flange 350 abuts against the top of the protective cover 800. The protective cover 800 supports the temperature sensor 300 through the positioning flange 350. The positioning flange 350 can achieve its support and fixation in the height direction through the supporting effect of the end of the protective cover 800, and further ensure that it can smoothly contact the protective cover 500 and detect the temperature.

[0041] In some embodiments, referring to Figure 3 , the protective cover 800 is provided with a buckle 850 and is fixedly connected to the base 100 or components inside the base 100 through the buckle 850. The buckle 850 enables the protective cover 800 to be connected and fixed to the base 100 or its internal components through the engagement effect, so that the temperature sensor 300 can be stably installed in the base 100. Moreover, the buckle 850 also has the advantage of being simple to disassemble and assemble, so it can provide convenience for the overall assembly.

[0042] Specifically, the middle part of the protective cover 800 has an installation ring, and the end face of the installation ring is placed on the raised position inside the base 100, so as to support the whole protective cover 800. The buckle 850 is arranged below the installation ring.

[0043] Furthermore, the buckle 850 can be fixedly connected to the heating plate inside the base 100.

[0044] In some embodiments, referring to Figure 1 , the protective cover 500 includes an aluminum cover and can conduct heat. The aluminum cover capable of conducting heat can smoothly transfer the heat to the temperature sensor 300, so that the temperature sensor 300 can smoothly and accurately detect the temperature.

[0045] It can be anticipated that the protective cover 500 can also be made of other heat-conducting materials, such as iron, copper, etc. Therefore, the specific implementation manner is not unique, but can be adjusted accordingly according to the actual situation, and is not limited here.

[0046] The second aspect of the present utility model provides an embodiment of an induction cooker, including the above heat sensing structure. When the cookware is placed on the top plate 700, the base 100 can heat and cook the cookware and the food ingredients inside it through the eddy current effect of the electromagnetic coil. During this process, the temperature sensor 300 can detect the temperature of the cookware or the top plate 700 in real time, so as to timely understand the specific temperature situation during cooking, and thus provide convenience for the cooking process. The protective cover 500 can not only provide direct and effective protection for the temperature sensor 300, and because the top of the protective cover 500 is flush with the top of the top plate 700, the two can jointly bear the collision force caused by the placement of the cookware. Moreover, the flushness of the protective cover 500 and the top plate 700 also makes it difficult to form a secondary collision effect between the top plate 700 and the protective cover 500 when the cookware is placed, thereby avoiding collision and damage to the protective cover 500 and the temperature sensor 300 by the top plate 700. In addition, the flushness of the protective cover 500 and the top plate 700 can also make the cookware obtain a more stable supporting effect when placed on the top plate 700, thereby ensuring that the cooking operation can be carried out more stably and reliably.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present utility model.
