The key to a good pump head is to pay special attention to the following areas:

1. For glass beads or steel balls under the spring, the sealing here is very important, which is related to the force of upward flushing of the liquid in the spring cavity. If the liquid leaks here, when the pressing handle is pressed, some of the liquid will leak into the bottle, thus affecting the effect of liquid spraying.

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, there will be a certain resistance when the liquid rushes up to the nozzle, and the liquid will flow back. If there is leakage, the spray effect will also be affected.

4. Nozzle design. The quality of nozzle design is directly related to the spray effect. Please refer to the next page for details on nozzle design.

Therefore, the function of the general pump head also detects these four positions, and other appearance and coordination problems are detected conventionally.
