【detailed description】

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, so as to define the protection scope of the utility model more clearly.

A water purifier control waterway on-off device, as shown in Figure 1 to Figure 4, the water purifier control waterway on-off device in this embodiment includes a valve body 1 and a valve seat 2 connected to each other, the valve body 1 is provided with The water inlet 10, the middle part of the valve body 1 is provided with a guide rail 11, and the valve body 1 is provided with a water tank 12 outside the guide rail 11. 31 float 3, the lower end of the guide rail 11 is provided with a sliding hole 13, the interior of the sliding hole 13 is provided with a columnar magnet 4 that moves up and down along the sliding hole 13, and a return spring 41 is provided between the columnar magnet 4 and the top of the sliding hole 13 , the valve seat 2 is provided with a water inlet 21 and a water outlet 22, a pipeline port 23 is provided on the pipeline connected between the water inlet 21 and the water outlet 22 in the valve seat 2, and a sealing rubber plug 24 is provided on the lower side of the end of the columnar magnet 4 , a seal 5 for blocking and opening the pipeline opening 23 is provided on the pipeline opening 23 connecting the water inlet 21 and the water outlet 22 in the valve seat 2;

The sealing member 5 separates the inner cavity of the valve seat 2 into upper and lower cavities. The sealing member 5 is provided with a conduction hole 51 connecting the upper and lower cavities of the valve seat 2 to maintain the water pressure balance in the upper and lower chambers. The central part of the sealing member 5 is provided with a drain Pressed pilot hole 52.

A sealing rubber pad 20 is provided at the joint between the valve body 1 and the valve seat 2 , and an upper cover 14 is provided on the top of the valve body 1 .

In this embodiment, the buoyancy of the water in the water tank 12 of the valve body 1 is used to control the float 3 with the ring magnet 31, and then the float 3 with the ring magnet 31 drives the columnar magnet 4, and the columnar magnet 4 is used to press down and push The sealing rubber plug 24 and the sealing member 5 provided on the lower side open or close the pipeline opening 23 between the water inlet 21 and the water outlet 22; The pipe opening 23 between 22 is open, that is, the water in the water tank 6 does not exceed the overflow port 61.
