The China Foam Pump(KEXON) is also generally called a Foam pressure pump. It can be used almost everywhere in life, like cosmetics, skin care products, detergents, and other aspects. When using, we first press the air in the Foam storage chamber (that is, the plastic tube that can wash the hair water). When the air is exhausted, press the pump head again. After the loose hand, the spring in the pump head. To restore the original state, a vacuum will be formed in the Foam storage chamber to generate a negative pressure. At this time, the pressure in the container is consistent with the atmospheric pressure, and then the pressure in the Foam storage chamber is small and the pressure inside the container is large. Due to the pressure difference, the atmosphere will press the Foam around the reservoir cavity into the reservoir, giving the impression that the pump head sucks up the Foam.
The specific principle is as follows: First press-When we press the actuator for the first time, we push the sub-stem together with the main stem to compress the spring. During the compression spring, the outer wall of the piston rubs against the inner wall of the body to urge the piston to open the discharge hole of the sub-stem; when the piston slides down, the body is discharged through the secondary sub-stem discharge hole; Reciprocating multiple presses- all the air in the body is discharged.
Aspirate-After pressing the actuator through the main stem, the sub-stem, the piston, the common compression spring to discharge the air in the body , release the actuator, the spring moves upward due to the loss of pressure. At this time, the piston also moves downward through the inner wall of the friction body, and the sub-stem The discharge hole is closed; at this time, the Foam storage chamber in the body forms a vacuum suction state, and the glass ball. Store the Foam-press the head several times, and store the Foam to the body by multiple aspirations until the Foam is full. Discharge-when the Foam in the body reservoir is full, press the actuator again and the Foam passes through the discharge hole directly from the actuator. )
