Embodiments of the invention

In the following description, a lot of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

As shown in Figures 1 to 3, a dust-proof kettle cover, hereinafter referred to as "the device". The device includes a cover and a dust cover 9. The cover body includes a sealing plug 1, a support column 6, a pressing switch 4, a fixing block 2, a compression spring 5, and an arc-shaped abutting rod 11. The sealing plug 1 is fitted into the upper part of the kettle by screw connection, and the support The column 6 is located in the center of the entire cover body and one end is connected above the sealing plug 1, and the other end extends outward to below the upper surface of the entire cover body. The fixing block 2 is installed above the sealing plug 1 and symmetrically arranged on two supporting columns 6 On the other hand, the compression spring 5 is installed on the periphery of the support column 6, and the lower end is connected to the fixed block 2, and a locking block is installed at the fixed block 2 to prevent relative sliding. The upper part is connected with the upper surface of the cover, so The push switch 4 is integrated with the upper surface of the cover, and when the push switch 4 is pressed downward, the movable slider 3 installed corresponding to the kettle body 15 slides down, and the push switch 4 is installed at the end close to the mouth of the kettle.
