[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] like Figure 1-Figure 6 As shown, an ultra-thin induction cooker is provided, including a bottom shell 1, an electrical cavity 101 for placing electrical components is provided in the middle of the bottom shell 1, a control cavity 102 is provided on the front side of the bottom shell 1, a heat dissipation portion 103 is provided on the rear side of the bottom shell 1, a first reinforcement portion 104 is provided between the control cavity 102 and the electrical cavity 101, a second reinforcement portion 1021 is provided on the control cavity 102, the heat dissipation portion 103 is extended upwardly relative to the electrical cavity 101 and a third reinforcement portion 1031 is provided on the heat dissipation portion 103.

[0027] Specifically, the front and rear sides of the bottom shell 1 avoid deformation or breakage of the bottom shell 1 due to temperature increase through the first reinforcement part 104, the second reinforcement part 1021 and the third reinforcement part 1031, thereby extending the service life of the ultra-thin induction cooker, improving the product's durability and user satisfaction, and having a simple structure and reliable performance.

[0028] Furthermore, the heat dissipation portion 103 is arranged to protrude upwardly from the electrical cavity 101 to prevent liquid from flowing from the heat dissipation portion 103 into the electrical cavity 101, thereby reducing the risk of short circuit or burnout of components in the induction cooker.

[0029] Further, if Figure 2 and Figure 3 , Figure 5 and Figure 6 As shown, the first reinforcement portion 104 is connected from the electrical cavity 101 toward the control cavity 102 in an inclined downward arc transition.

[0030] Specifically, the downwardly inclined arc transition connection of the first reinforcement portion 104 can effectively disperse and relieve various stresses and thermal stresses to which the bottom shell 1 is subjected during operation, and is easier to implement in the manufacturing process, thereby reducing manufacturing difficulty and cost, and improving production efficiency.

[0031] Further, if Figure 2 and Figure 3 , Figure 5 and Figure 6 As shown, the second reinforcement portion 1021 is recessed downward in the middle of the control cavity 102 .

[0032] Specifically, the second reinforcement portion 1021 is recessed downward, which can effectively enhance the bending and deformation resistance of the control cavity 102 when subjected to stress, and enables the stress to be more evenly distributed in the middle of the control cavity 102, thereby reducing stress concentration and avoiding material fatigue and damage caused by stress concentration.

[0033] Furthermore, the height dimension of the control cavity 102 is lower than the height dimension of the electrical cavity 101 .

[0034] Specifically, by reducing the height of the control cavity 102, the overall structure can be made thinner, space utilization can be optimized, and the structure can be more compact and stable.

[0035] Further, if Figure 2 and Figure 3 , Figure 5 and Figure 6 As shown, a control panel 2 is disposed on the control cavity 102 , and a support column 3 for supporting the control panel 2 is disposed on the control cavity 102 and the first reinforcement portion 104 , and a plurality of first reinforcement ribs 301 are evenly disposed on the support column 3 in a circumferential direction.

[0036] Specifically, the design of the support column 3 and the first reinforcing rib 301 provides a stable support, so that the control panel 2 will not shake or loosen during installation and operation, ensuring the accuracy of operation and user experience. The setting of the reinforcing rib 301 increases the strength of the support column 3 to prevent it from deformation or breakage when subjected to external force.

[0037] Further, if Figure 5 and Figure 6 As shown, the first reinforcement portion 104 is transversely disposed between the electrical cavity 101 and the control cavity 102 , and the second reinforcement portion 1021 is transversely disposed on the control cavity 102 .

[0038] Specifically, the first reinforcement portion 104 is equal to the width of the bottom shell, so that the first reinforcement portion 104 increases the structural strength between the electrical cavity 101 and the control cavity 102; the transversely arranged second reinforcement portion 1021 provides additional support and reinforcement, so that the control cavity 102 can maintain its shape and stability when subjected to external force or internal thermal stress.

[0039] Further, if Figure 5 and Figure 6 As shown, the heat dissipation portion 103 is provided with a plurality of heat dissipation grille holes 1032 evenly spaced apart, and the third reinforcement portion 1031 is located between two adjacent heat dissipation grille holes 1032 ; the third reinforcement portion 1031 is extended upward relative to the heat dissipation portion 103 .

[0040] Specifically, the heat dissipation grille holes 1032 are arranged at even intervals, which can effectively increase the heat dissipation area, improve the air circulation efficiency, enhance the heat dissipation effect, and prevent the induction cooker from overheating during operation; the design of the heat dissipation grille holes 1032 enables heat to be quickly discharged from the inside, keeps the operating temperature of the electrical components within a reasonable range, and extends their service life; the third reinforcement part 1031 is arranged between adjacent heat dissipation grille holes 1032, which can effectively enhance the overall rigidity and strength of the heat dissipation part and prevent deformation when heated or stressed; the design of the third reinforcement part 1031 extending upward provides additional support, making the heat dissipation part 103 more stable in the vertical direction and increasing the pressure resistance and deformation resistance.

[0041] Further, if Figure 2 As shown, the electrical component includes a coil disk 4, and a positioning column 5 for mounting the coil disk 4 is provided on the electrical cavity 101. The positioning column 5 is circumferentially provided with a surrounding edge 501, and a second reinforcing rib 502 is provided between the surrounding edge 501 and the positioning column 5. The coil disk 4 is fixedly mounted on the positioning column 5 by screws, and the coil disk 4 is spaced relative to the bottom shell 1 through the positioning column 5.

[0042] Specifically, by arranging a positioning column 5 for installing the coil disk 4 in the electrical cavity 101, as well as the design of the surrounding edge 501 and the second reinforcing rib 502, not only the installation accuracy and stability of the coil disk are improved, but also the strength and durability of the overall structure are significantly enhanced. The positioning column 5 enables the coil disk 4 to be spaced relative to the bottom shell 1, thereby improving the heat dissipation performance and preventing overheating.

[0043] Further, if Figure 2 As shown, the bottom shell 1 is provided with an anti-magnetic shielding component 6 corresponding to the coil disk 4 , and a buckle 7 for fixing the anti-magnetic shielding component 6 is provided on the bottom shell 1 . The anti-magnetic shielding component 6 is fixed to the bottom shell 1 via the buckle 7 .

[0044] Specifically, an anti-magnetic shielding component 6 is arranged at a position of the bottom shell 1 corresponding to the coil disk 4, and the anti-magnetic shielding component is fixed with a buckle 7. The installation is simple and the replacement is convenient. The anti-magnetic shielding component 6 not only effectively shields electromagnetic interference, ensures electromagnetic compatibility and safety of use, but also simplifies the installation and maintenance process, thereby enhancing the overall performance of the product and user experience.

[0045] It should be noted that the anti-magnetic shielding component 6 can also be formed in one piece with the bottom shell 1 .

[0046] Further, if Figure 2 As shown, the electrical components also include a circuit board 8 and a cooling fan 9 for dissipating heat from the coil disk 4 and the circuit board 8. The cooling fan 9 and the circuit board 8 are both arranged on the electrical cavity 101. The electrical cavity 101 is provided with an air guide plate 10. The cooling fan 9 allows cold air to flow to the coil disk 4 and the circuit board 8 through the air guide plate 10.

[0047] By arranging the circuit board 8 and the cooling fan 9 in the electrical cavity 101 and guiding the cold air to the coil disk 4 and the circuit board 8 through the air guide plate 10, not only the heat dissipation effect of the key components is effectively improved, but also the stability and reliability of the system are significantly enhanced.

[0048] Furthermore, the coil disk 4 and the cooling fan 9 are at the same height as the circuit board 8, thereby making the whole structure thinner.

[0049] Further, if Figure 2 As shown, the ultra-thin induction cooker further includes a cover body 11 arranged on the bottom shell 1 .
