When the locking motor 27 drives the rotating frame 23 to rotate counterclockwise, the suspension 29 is now in contact with the second linkage arm 32 and drives the top cover 4 to rotate counterclockwise. When the locking block 19 moves to the position of the locking cavity 16, the locking block 19 automatically pops out and inserts into the locking cavity 16 under the action of the reset spring 21 to complete the double locking. Then, a variety of raw materials are added to the kettle body 1 through the feeding port 34 at the top, and finally the stirring motor 35 is started.
