What is the working principle of emulsion pump head

When Sprayer Pumps we press the  for the first time, it presses the sub-pillar  through the connected main column  to compress the spring ; during the compression of the spring, the outer wall of the piston  passes through the body  friction of the inner cavity wall causes the piston to open the discharge hole of the sub column ; when the piston  slides down, the air in the body  passes through the sub column  that has been opened Discharge hole discharge.

All the air in the body  is discharged; press the hand through the main column , the sub-column , the piston , and the spring  to compress the body After the air inside is discharged, release the The size of the pump head is determined by the diameter of the matching bottle. The spray specification is 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time. It is generally used for packaging of perfume, gel water and other products, and the same caliber takes over The length can be determined according to the height of the bottle. Emulsion pump specifications range from 16ml to 38ml, and the water output is 0.28ml/time-3.1ml/time.

It is generally used in creams and washing products. Special dispensers such as foam pump heads and hand buckle sprinklers. The foam pump head is a non-inflatable hand pressure pump head. It does not need to be inflated to generate foam. Only a light press can produce quantitative high-quality foam. Generally equipped with special bottles. Hand button spray heads are commonly used in cleaning products and other products. and the spring  moves back up due to the loss of pressure.

At this time, the piston  also moves down through the inner wall of the friction body  to move the auxiliary column The discharge hole of  is closed; at this time, the liquid storage cavity in the body  forms a vacuum suction state, suck the glass ball  upward, and suck the liquid in the bottle through the suction tube Inside the body  liquid storage chamber. Press the button multiple times, and store the liquid to the body by sucking the liquid multiple times until the liquid is full. When the liquid in the  reservoir is full, press the  again and the liquid will be ejected directly from the  through the discharge hole.
