When the pressing Lotion Pump(KEXON) is pressed down manually, the volume in the spring chamber is reduced and the pressure is increased, the liquid enters the nozzle chamber through the hole of the valve core, and then the liquid is sprayed out through the nozzle. When the pressing handle is loosened, the volume in the spring chamber is increased to form negative pressure, the sphere is opened under the negative pressure effect, the liquid in the bottle enters the spring chamber, and then a certain amount of liquid is already stored in the valve body, and when the handle is pressed again, the liquid stored in the valve body is washed up and sprayed out through the nozzle.
