It uses the principle of atmospheric balance to spray out the liquid in the bottle by pressing, and the high-speed flow of liquid will also drive The gas flow near the nozzle orifice makes the speed of the gas near the nozzle orifice increase and the pressure decreases, forming a local negative pressure zone. Thus, the ambient air is mixed into the liquid to form a gas-liquid mixture, and the liquid produces an atomization effect.
