In the suction seat at the bottom of the single tube sprayer, there is an inlet valve. There is a water outlet valve on the outer wall of the tube inside the gas chamber. There are copper balls in both valves. During the work, the pressure of the steel ball jumps up and down to open and close the valve to control the flow of the liquid.

When the plug rod rises, the space inside the tube of the foot tube suddenly increases, thus forming a partial vacuum. Under the action of atmospheric pressure, the liquid medicine punches the copper ball in the inlet valve and enters the tube. When the plug stem is pressed, the copper ball in the inlet valve closes the inlet hole. The liquid that has entered the tube of the tube can only flow out from the upper part of the tube of the tube through the hole of the outlet valve, push the copper ball out of the water valve, and enter the air chamber. The liquid is gradually increased, and the air in the air chamber is compressed to generate pressure. The greater the compression ratio, the greater the pressure generated.

The pressurized liquid is vortexed through a water outlet joint through a conduit (hose, spray bar, etc.) into the vortex chamber of the nozzle for high-speed swirling. Due to the centrifugal action of the vortex and the difference between the pressure inside and outside the orifice, the liquid solution forms a mist after passing through the orifice.
