In life, we often see the hand sanitizer in such a bottle, press the pump head on the top of the bottle, and the hand sanitizer comes from the infusion tube.
The working principle of the pump head is the same as that of the piston pump. It is also the use of the piston to move and the opening of the single-phase valve. The air in the liquid removal bucket is closed to cause internal and external pressure rubbing, so that the liquid rises under atmospheric pressure and is discharged from the liquid discharge pipe. There is a pressing type suction liquid structure in the hand sanitizer bottle, which mainly comprises a liquid guiding tube, a radial leaf ball valve, a spring yellow, a hollow plunger, a piston, a liquid discharging tube and a dewatering liquid. When the liquid is pressed down by hand, the pressure in the barrel is large, the spring is closed by the compressed leaf stem valve, and at the same time, because the piston moves downward, the liquid outlet on the hollow plunger is opened, and the liquid removal is performed. The liquid in the hole flows out of the tube from the liquid in the liquid removal hole. When the hand is released, the yellowing is restored, so that the piston moves upward and the pressure in the liquid removal tank is reduced, and the liquid removal hole on the hollow plunger is closed. The leaf stem valve is opened, and the liquid enters the liquid removal tank from the liquid guiding tube through the leaf stem valve under the action of atmospheric pressure. In this way, the piston reciprocates up and down in the drum and continuously sucks the liquid out of the bottle.
There are many customers who don't understand the principle of the pump. In fact, the principle of the pump and the principle of the hand sanitizer are similar, except that the pump has a motor composition that uses the motor to make the pressure larger and more convenient to use.
