Lotion pump, also known as push-type Lotion pump, is a kind of liquid distributor that uses the principle of atmospheric balance to pump out the material liquid in the bottle by pressing and replenish the outside atmosphere into the bottle.
The key to a good pump head is to pay special attention to the following areas:
1. The sealing of glass beads or steel balls under the spring is very important here, which is related to the force of upward flushing of the liquid in the spring cavity. If there is leakage here, when the pressing handle is pressed, some of the liquid will leak into the bottle, thus affecting the spraying effect of the liquid.
2. It is the sealing ring at the upper end of the valve body. If there is leakage here, the force bottom of liquid pumping up will decrease when the pressure handle is released, resulting in a small amount of liquid stored in the valve body, which will also affect the spray effect.
3. The matching between the pressure handle and the valve core. If there is loose matching and leakage here, there will be certain resistance when the liquid rushes up to the nozzle, and the liquid will flow back. If there is leakage here, the spray effect will also be affected.
4. The design of the nozzle and the quality of the nozzle design are directly related to the spray effect. Please refer to the next page for details on the nozzle design.
Therefore, the function of the general pump head also detects these four positions, and other appearance and coordination problems are detected conventionally.
