[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] refer to Figures 1 to 5The present application provides a novel mica heating plate assembly structure, comprising: a heat preservation cover 1 and a mica heating plate 2 arranged in the electric rice cooker, the mica heating plate 2 being detachably connected to the inner bottom surface of the heat preservation cover 1, the inner bottom surface of the heat preservation cover 1 being circumferentially evenly provided with at least two claws 3, a buckle 4 being provided at the bottom of the mica heating plate 2 corresponding to the claws 3, the claws 3 being engaged with the buckle 4, a pin 5 being provided at the lower part of the mica heating plate 2, and a through hole 6 for the pin 5 to pass through being opened on one side of the heat preservation cover 1.

[0022] In some embodiments, the claw 3 is stamped from the insulation cover 1, and the claw 3 has a first opening 7 for the buckle 4 to enter and a latching position for the buckle 4 to engage. The first opening 7 is set in a clockwise direction or in a counterclockwise direction. The claw 3 is integrally formed with the insulation cover 1. The insulation cover 1 is generally made of metal, so the stamped claw 3 has a certain elasticity, which facilitates the entry of the buckle 4.

[0023] In some embodiments, the locking position includes a first locking point 8 parallel to the first opening 7 and a second locking point 9 arranged on both sides of the first locking point 8. The second locking point 9 is provided with a boss structure downward. After the buckle 4 enters the first locking point 8 along the first opening 7, it is blocked and fixed by the second locking points 9 on both sides to prevent the mica heating plate 2 from shifting after being locked.

[0024] In some embodiments, the mica heating plate 2 includes an upper cover 10, a bottom plate 11 and a heating component. The heating component is arranged between the upper cover 10 and the bottom plate 11. The buckle 4 is arranged at the bottom of the bottom plate. The buckle 4 has a second opening arranged outward.

[0025] In some embodiments, the heating component includes a mica board and a heating wire, both ends of the heating wire are respectively disposed in the pins 5, and the middle portion of the heating wire is wound around the mica board.

[0026] In some embodiments, a support step 12 is provided on the edge of the upper cover 10 extending downward, and the support step 12 contacts the inner bottom surface of the thermal insulation cover 1. The support step 12 can prevent the mica heating plate 2 from being excessively pressed downward during assembly, causing deformation of the claw 3 or the buckle 4.

[0027] In the first embodiment, the heat preservation cover 1 is provided with two claws 3, and the mica heating plate 2 is provided with two buckles 4 corresponding to the number of the claws 3, and the angle between the claws 3 is 180°.

[0028] In the second embodiment, the heat preservation cover 1 is provided with three claws 3, and the mica heating plate 2 is provided with three buckles 4 corresponding to the number of the claws 3, and the angle between the claws 3 is 120°.

[0029] In the third embodiment, the heat preservation cover 1 is provided with four claws 3, and the mica heating plate 2 is provided with four buckles 4 corresponding to the number of the claws 3, and the angle between the claws 3 is 90°.

[0030] The specific assembly process of this application is: insert the pin 5 of the assembled mica board heating plate into the through hole 6, and then rotate the mica heating plate 2 in the opposite direction according to the direction of the claw 3 (clockwise or counterclockwise), so that each buckle 4 is engaged in the claw 3, and the mica heating plate 2 is fixed in the insulation cover 1 under the blocking of the boss structure of the second engaging point 9.

[0031] In this application, the claws 3 on the thermal insulation cover 1 cooperate with the buckles 4 at the bottom of the mica heating plate 2. During the assembly process, the mica heating plate 2 can be fixed on the thermal insulation cover 1 by simply rotating the mica heating plate 2. The assembly process is quick and easy, saving a lot of manpower and material resources and improving assembly efficiency.
