The inner wall groove is a reserved track. The sealing ring assembly and the pot body are placed in the reserved track by the frying basket assembly connected as one. The above structure further facilitates the structural design of fixing the sealing ring assembly in the machine body.

[0007] An upper buckle groove is provided at the top of the insertion end of the upper pressing plate of the sealing ring assembly, and raised upper flat key edges are symmetrically provided on the edges of the upper pressing plate on both sides of the upper buckle groove, and raised lower flat key edges are symmetrically provided on the edges of the lower pressing plate corresponding to the upper flat key edges, and lower buckle grooves are respectively provided in the middle of the lower pressing plate corresponding to the upper buckle groove, and in the arc-shaped edges of the middle of the lower pressing plate and the lower flat key edges on both sides, and the upper flat key edge of the upper pressing plate and the lower flat key edge of the lower pressing plate are buckled and fixed to the sealing ring groove of the frying basket assembly at the pot mouth above the pot body. The above structure facilitates the positioning and buckling of the upper pressing plate and the lower pressing plate of the sealing ring assembly corresponding to the concave and convex grooves at the reserved track.

[0008] The upper buckle groove of the upper pressing plate is symmetrically provided with an upper notch groove on one side edge, and the lower pressing plate edge corresponding to the upper notch groove is symmetrically provided with a lower notch groove. The above structure further facilitates the upper pressing plate and the lower pressing plate of the sealing ring assembly to be positioned and buckled with the concave and convex grooves at the reserved track.

[0009] The top of the machine body is provided with a top cover, a control panel is provided on the machine head above the opening of the machine body, an air guide cover is provided above the metal insulation layer in the machine head, a plastic centrifugal fan blade is provided in the air guide cover, the plastic centrifugal fan blade and the metal centrifugal fan blade are connected to the transmission shaft of the motor at the same time, and an air outlet cover is provided on the machine body at the air outlet communicating with one side of the metal insulation layer and the air guide cover.
