Working Principle of Lotion Pump
April 18 @ 8:00 am - 5:00 pm
Lotion Pump(KEXON) is also commonly called hand sanitizer pressure pump. Life can be used almost everywhere, such as cosmetics, skin care products, detergent, detergent, etc., many. When in use, we first expel the air from the inside of the liquid storage chamber (that is, the plastic tube capable of absorbing shampoo) by pressing. When the air is exhausted, we press the pump head again. As the spring of the pump head inside is to be restored to its original state after releasing, the liquid storage chamber inside will form vacuum and generate negative pressure. At this time, the pressure of the container inside keeps the same as atmospheric pressure, thus causing the condition of low pressure in the liquid storage chamber inside and high pressure in the container. At this time, due to the pressure difference, the atmosphere will press the liquid around the liquid storage chamber opening into the liquid storage chamber inside, giving the impression that the pump head sucks the liquid up.
The specific principles are as follows: 1. First press-when we press the press 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 pushes the piston to open the discharge hole of the secondary column through friction with the inner wall of the body. When the piston slides downwards, the air in the body is discharged through the opened secondary column discharge hole; 2. Press repeatedly and repeatedly-to exhaust all the air in the body; 3. Suction-Press the press head by hand to discharge the air in the body through the main column, the auxiliary column, the piston and the common compression spring. Release the press head. The spring moves back (up) due to loss of pressure. At this time, the piston also moves down through the inner wall of the friction body to close the discharge hole of the auxiliary column. At this time, the liquid storage cavity in the body is in a vacuum liquid absorption state, the glass ball is sucked upwards, and the liquid in the bottle is sucked into the liquid storage cavity of the body through a suction pipe. 4. Storage of Liquid-Press the pressing head several times, and store the liquid to the body by sucking the liquid many times until the liquid is fully stored. 5. Liquid Discharge-When the liquid in the liquid storage cavity of the body is full, press the press head again and the liquid will be directly ejected from the press mouth through the discharge hole;
