When the floating cover 6-24 floats upwards, namely the water storage tank 6-25 begins to store water, the floating cover 6-24 pushes the first connecting rod 6-1 to rotate by taking the hinge point 6-7 as a circle center, so that the second connecting rod 6-2 is driven to rotate downwards, and the gland 6-6 is pushed to move downwards.

The water inlet valve 6-5 further comprises a third valve body 6-12 of a cavity, the cavity in the third valve body 6-12 is communicated with the water inlet pipe 11, two water supply holes 6-13 communicated with the first valve body 6-17 and the second valve body 6-8 respectively are arranged on the upper end face of the third valve body 6-12, and the lower ends of the first plug rod 6-15 and the second plug rod 6-9 can be inserted into the water supply holes 6-13 to form plugging of the water supply holes 6-13.
