How to Sueeze Ot Lquid with Screw Lotion Pump?

  • Screw lotion pump, generally called hand sanitizer pressure pump. It can be used almost everywhere in life, such as cosmetics, skincare products, detergents, detergents, etc., many. When using it, we first discharge the air in the reservoir (that is, the plastic tube that can absorb the shampoo) by pressing. When the air is exhausted, press the pump head again. After letting go, the spring in the pump head To restore the original state, a vacuum will be formed in the liquid storage chamber, and negative pressure will be generated. At this time, the pressure in the container is consistent with the atmospheric pressure. Then, the pressure in the liquid storage chamber is low and the pressure in the container is high. , Due to the pressure difference, the atmosphere will press the liquid around the mouth of the liquid storage cavity into the liquid storage cavity, giving people the feeling that the pump head sucks up the liquid.

    The specific principle is as follows:

    1. First press--When we press the head for the first time, the press head drives the auxiliary column to compress the spring together through the connected main column; in the process of compressing the spring, the outer wall of the piston rubs against the inner cavity wall of the body to prompt the piston to open the auxiliary column. Discharge hole; When the piston slides down, the air in the body is discharged through the discharge hole of the auxiliary column that has been opened;
    2. Press back and forth many times-exhaust all the air in the body;
    3. Liquid suction---press the head by hand to pass through the main column, sub-column, piston, and the common compression spring to expel the air in the body, then loosen the head, the spring loses pressure and moves back, and the piston also passes through at this time Rub the inner wall of the main body downward to close the discharge hole of the auxiliary column; at this time, the liquid storage cavity in the main body forms a vacuum suction state, and the glass ball is sucked up, and the liquid in the bottle is sucked into the main liquid storage cavity through the straw Inside.
    4. Storing liquid-press the head several times, and store the liquid in the body by repeatedly sucking the liquid until the liquid is full.
    5. Liquid discharge--When the liquid in the body's liquid storage chamber is full, press the head again and the liquid will be sprayed directly from the nozzle through the discharge hole.
