The utility model discloses the working process is as follows:

And (3) an exhaust process: it is assumed that in the initial state there is no liquid in the working chamber (between the piston seat 9 and the non-return valve 11). Pressing the pressing head 2, the compression pipe 6 drives the piston 8, the piston 8 pushes the piston seat 9 to move downwards, the second spring 10 is compressed, the volume in the working chamber is compressed, the air pressure is increased, and the check valve 11 seals the water suction pipe 12. Since the piston 8 and the piston seat 9 are not completely closed, the gas pushes the gap between the piston 8 and the piston seat 9 apart, and the gas escapes.

and (3) water absorption process: after exhausting, the pressing head 2 is released, the compressed second spring 10 is released, the piston seat 9 is pushed to move upwards, the gap between the piston seat 9 and the piston 8 is closed, and the piston 8 and the compression pipe 6 are pushed to move upwards together. The volume in the working chamber is increased, the air pressure is reduced and is approximate to vacuum, so that the check valve 11 is opened, the air pressure above the liquid in the container presses the liquid into the working chamber, and the water absorption process is completed.

and (3) water outlet process: the principle is the same as the exhaust process. In contrast, the working chamber is now filled with liquid. When the pressing head 2 is pressed down, on one hand, the check valve 11 seals the suction pipe 12 to prevent the liquid from returning from the suction pipe 12 to the container; on the other hand, as the liquid is squeezed, the liquid will flush the gap between the piston 8 and the piston seat 9, flow into the compression tube 6 and out of the nozzle 4.

The reason for the formation of the spray is as follows: when the fluid flows from the compression pipe 6 to the connection pipe 3 and is sprayed out from the small-hole nozzle 4, because the liquid is incompressible fluid and the nozzle 4 has a small opening, if the pressing is smooth, when the liquid flows out from the small hole, the liquid flow rate is large, namely, the air has a large flow rate relative to the liquid, which is equivalent to that the high-speed air flow impacts the water drops, and the air impacts the large water drops into small water drops, so that the water drops are refined step by step. Meanwhile, the liquid flowing at high speed can also drive the gas near the nozzle 4 to flow, so that the speed of the gas near the nozzle 4 is increased, the pressure is reduced, and a local negative pressure area is formed. Therefore, ambient air is mixed into the liquid to form a gas-liquid mixture, so that the liquid generates an atomization effect.
