[0031] like Figures 1 to 8 As shown, when the driving member 50 drives the middle of the elastic diaphragm 30 to deform downward or move downward, suction is generated in the diaphragm cavity 41, and the air pressure in the diaphragm cavity 41 pulls the first umbrella surface 21, and the first umbrella surface 21 deforms downward, so that the first umbrella surface 21 is tightly attached to the outside of the water outlet 441, and the one-way water inlet valve 60 is opened, and the liquid in the water inlet channel 42 is ejected into the diaphragm cavity 41; the first step portion 222 is tightly attached to the surface of the first partition plate 44, and the first step portion 222 sealing cover is on the surface of the first fixing hole 442 to prevent outside air from entering the diaphragm cavity 41.

The first umbrella surface 21 is deformed upward, so that the first umbrella surface 21 is separated from the water outlet hole 441, and the liquid in the diaphragm cavity 41 is ejected from the water outlet hole 441.

[0038] like Figures 1 to 8 As shown, when the driving member 50 drives the middle of the elastic diaphragm 30 to deform downward or move downward, suction is generated in the diaphragm cavity 41, and the suction in the diaphragm cavity 41 pulls the second umbrella surface 61 to deform into the diaphragm cavity 41, and the second umbrella surface 61 is separated from the water inlet hole 451, and the liquid in the water inlet channel 42 is ejected into the diaphragm cavity 41 through the water inlet hole 451.
