[0019] 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.

[0020] refer to Figures 1 to 5 The present application provides a quick assembly structure of a mica heating plate, comprising: a heat preservation cover 1 and a mica heating plate 2 arranged in an electric rice cooker, the edge of the mica heating plate 2 extending downwardly to be provided with a support step 3, the bottom surface of the mica heating plate 2 extending downwardly to be provided with at least two clamping columns 4, the lower portion of the clamping columns 4 being bent to form a clamping claw 5, the inner bottom surface of the heat preservation cover 1 being provided with at least two clamping positions 6 for the clamping columns 4 to pass through, the lower portion of the mica heating plate 2 being provided with a pin 7, and a through hole 8 for the pin 7 to pass through being provided on one side of the heat preservation cover 1.

[0021] In some embodiments, the mica heating plate 2 includes an upper cover 9, a base plate 10 and a heating component 11. The heating component 11 is arranged between the upper cover 9 and the base plate 10. The clamping column 4 is arranged at the bottom of the base plate. The clamping claw 5 is bent outward, and the mica heating plate 2 is fixed to the thermal insulation cover 1 by the clamping claw 5.

[0022] In some embodiments, the clamping column 4 is formed by stamping the chassis.

[0023] In some embodiments, the heating component 11 includes a mica board and a heating wire, both ends of the heating wire are respectively disposed in the pins 7 , and the middle portion of the heating wire is wound around the mica board.
