[0021] Furthermore, the protective mechanism described in the utility model includes an annular enclosure 1 fixedly connected to the outside of the base body 6, a disc 2 slidably arranged on the inside of the annular enclosure 1, a limit groove 21 provided on the inside of the disc 2, and a cover 5 slidably arranged on the inside of the limit groove 21, the disc 2 is provided with a through hole 4 corresponding to the coupler 7, the cover 5 is symmetrically arranged on both sides of the coupler 7, the disc 2 is provided with a driving component for driving the cover 5 to slide, and a rebound component is provided between the disc 2 and the annular enclosure 1. Specifically, the two covers 5 can be driven to slide in the limit groove 21 by the driving component to achieve the effect of opening or closing. After the cover 5 is opened, the kettle is placed on the disc 2. Under the deadweight of the kettle, the disc 2 moves down, the coupler 7 exposes the through hole 4, and is plugged into the connection port at the bottom of the kettle, and the kettle starts to work. When the kettle is picked up, the disc 2 automatically rises under the action of the rebound component.
[0022] Furthermore, the driving assembly in the utility model comprises an operating ring 3 rotatably arranged on the disc 2, a threaded hole 10 provided on the inner side of the blocking cover 5, a threaded rod 8 provided on the inner side of the threaded hole 10, and a gear 15 fixed to the end of the threaded rod 8, the outer side of the operating ring 3 is provided with a burr 9, and the surface of the disc 2 is provided with a mounting groove 14 matched with the operating ring 3, such as Figure 2 , Figure 4 , Figure 5 As shown, the thickness of the burr 9 is smaller than that of the operating ring 3, the mounting groove 14 is an annular groove opened on the top of the disc 2, and a groove matching the burr 9 is opened on the inner side of the annular groove. The operating ring 3 is installed on the inner side of the mounting groove 14 and can be rotated arbitrarily in the mounting groove 14, and is limited by the burr 9 so that the operating ring 3 cannot be separated from the mounting groove 14. Furthermore, the surface of the operating ring 3 is provided with an anti-slip groove 18, and the setting of the anti-slip groove 18 makes it convenient to move the operating ring 3.
