Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

As shown in fig. 1 to 3, a dust-proof kettle cover is hereinafter referred to as the device. The device comprises a cover body and a dust cover 9. The cover body comprises a sealing plug 1, a supporting column 6, a press switch 4, a fixing block 2, a compression spring 5 and an arc-shaped touch bar 11, wherein the sealing plug 1 is embedded in the kettle in a threaded manner, the supporting column 6 is positioned at the central position of the whole cover body, one end of the supporting column 6 is connected above the sealing plug 1, the other end of the supporting column extends outwards to the lower part of the upper surface of the whole cover body, the fixing block 2 is arranged above the sealing plug 1 and symmetrically arranged at two sides of the supporting column 6, the compression spring 5 is arranged at the periphery of the supporting column 6, the lower end of the compression spring is connected on the fixing block 2, a locking block is arranged at the fixing block 2 to prevent the fixing block from sliding relatively, the upper part of the fixing block is connected with the upper surface of the cover body, the press switch 4 and the upper surface of the cover body are integrally designed, the movable sliding block 3 which is arranged corresponding to the, one end of the arc-shaped touch rod 11 is connected to the fixed block 2 close to the kettle opening, and the other end of the arc-shaped touch rod extends upwards to touch the lower surface of the dustproof cover 9; the dustproof cover 9 is arranged at the kettle opening, a connecting plate is arranged between the dustproof cover 9 and the press switch 4, and an active suction assembly is arranged between the connecting plate and the dustproof cover 9.
