How To Make A Spray Pump Head

The spray pump is a very common auxiliary accessory for liquid containers in the field of household products such as cosmetics, washing products, and plant cultivation. It is used to press the liquid in the bottle to let the air and liquid flow out of the small hole quickly. The pressure near the small hole is very small, the air pressure above the liquid surface in the container is very high, and the liquid flows along the small hole below the small hole. After the tube rises and flows out from the upper opening of the thin tube, it is impacted by the airflow and diffuses into the air in the form of spray to form small airborne particles.

The existing relatively mature spray pump head settings include the pump body installation part with a lock bottle cap, the pump body installation part, the liquid inlet at the lower end of the pump chamber, the pump beads at the liquid inlet, the upper pump rod in the pump chamber, the upper The upper end of the pump rod extends out of the pump chamber, the upper end connection of the upper pump rod, the upper end connection of the upper pump rod, the lower end connection of the upper pump rod, the spray point on the button, the fog point where the spray point is connected to the spray channel, The positioning ring platform on the outer wall of the lower part of the upper pump rod, the upper end connection of the upper pump rod at the upper end of the upper pump chamber, the upper end connection of the upper pump rod, the upper end connection of the upper pump rod, the upper end connection of the upper pump rod, the upper The upper end joint of the pump rod, the upper end joint of the upper pump rod, and the upper end joint of the upper pump rod.

However, the spray pressure of this type of spray pump is completely determined by the finger pressure of the button. The greater the finger pressure, the greater the spray pressure. Because the pressure and action of the hand pump head are divided into speed, speed and severity, the spray effect is poor and the atomization is unstable. When pressing the bottom, even water droplets are sprayed directly from the nozzle, and the user feedback is not good.

However, there are still some defects in the pump core. First, the structure of the upper channel is small, and the liquid flows faster between the upper and lower channels. The pressure difference of the channel will form a spray shape again, which will affect people's experience of use.

The second is that after the lower channel is pressed to form, it still maintains a large pressure after spraying. At this time, release the finger pressure. During the spring reset process, it will still generate pressure on the pump beads at the lower end of the pump core, affecting the liquid inlet speed and The amount of liquid intake makes it difficult for the liquid after the pump core is reset to be completely filled, and a small amount of air is mixed in. Because the liquid is heavier than the air, the liquid will sink to the lower channel, and the gas will enter the upper channel. Therefore, after being placed for a long time, when the pump core sprays out at one time, the amount of mist produced is small, or even unable to produce mist. affect the use of sensation
