The spin chuck 20 is pivotally coupled to the upper cover body 10, that is, the spin chuck 20 is coupled to the upper cover body 10 and is pivotable relative to the upper cover body 10. The rotating chuck 20 may be located above the upper cover body 10. The rotating chuck 20 may be coupled to the upper cover body via a rotating shaft. As shown in FIG. 1, the middle portion of the rotating chuck 20 may be provided with a shaft hole for passing the rotating shaft. There are two card slots on the rotating chuck 20 (the number of the card slots may be more than two according to specific conditions, and the plurality of card slots may be spaced apart from each other or may be connected to each other, that is, the plurality of card slots may be connected to each other to form One slot), each of the card slots is formed as an arcuate card slot 201, and the plurality of arcuate card slots 201 are distributed along the circumferential direction of the spin chuck 20, and each of the arcuate card slots 201 is eccentric with respect to the center of the spin chuck 20. The arrangement, in other words, the center of each of the arcuate card slots 201 does not coincide with the center of the spin chuck 20, and the direction of extension of each of the arcuate card slots 201 is not along the circumferential direction of the spin chuck 20, but relative to the rotation. The circumferential direction of the chuck 20 extends obliquely.

It does not move, but stops moving on the inner peripheral wall of the curved card slot 201, and realizes the movement in the radial direction of the rotary chuck 20. When the column 40 moves, the fastener 30 connected thereto is rotated. The chuck 20 moves in the radial direction, and the fastening member 30 moves to engage with a structure on the outer pot, for example, a tooth or the like, and the electric pressure cooker realizes closing.

Wherein, since the elastic member 50 is disposed between the outer peripheral surface of the strut 40 and the inner peripheral wall of the arcuate card slot 201, the elastic member 50 is elastically deformed by force, and the radial force of the rotating chuck 20 against the strut 40 can be cancelled, thereby The radial force received by the strut 40 is reduced, the deformation of the strut 40 is reduced, and the elastic property of the elastic member 50 itself can effectively reduce the wear between the structural members, thereby improving their smoothness and stability. The electric pressure cooker is smoothly closed and the operation noise is small.

The opening operation of the upper cover assembly 100 according to the embodiment of the present invention is exactly the opposite of the closing operation, even if the rotating chuck 20 is forced to pivot in the other direction along its own axial direction (for example, counterclockwise), thereby driving The strut 40 moves in the opposite direction, thereby causing the engaging member 30 to move in the opposite direction, so that the separation from the outer pot can be achieved. Due to the presence of the elastic member 50, the opening operation is performed. It is smoother and less noisy.

An electric pressure cooker according to an embodiment of the present invention may include an outer pot, an inner pot, and an upper lid assembly 100 according to an embodiment of the present invention. The inner pot is disposed in the outer pot, and the outer pot can be provided with a fitting portion for engaging with the fastening component 30, so that the upper lid assembly 100 can be engaged with the outer pot, since the upper lid assembly 100 according to the embodiment of the invention has The above advantageous technical effects, therefore, the electric pressure cooker switch cover according to the embodiment of the invention is convenient, smooth and reliable, and has a long service life.
