Where Is The Key To High-quality Lotion Pump Head

      the lotion pump head is also called a pressurized lotion pump. It is a liquid dispenser that uses the principle of atmospheric balance to pump out the raw material liquid in the bottle by pressing and supplementing external air into the bottle.

      The main performance indicators of lotion pump head: air pressure multiple, pump output power, downforce, open cap torque, rebound speed, water inlet index, etc.

      When the pressing handle is manually pressed, the volume in the spring cavity decreases, and the pressure increases. The liquid enters the nozzle cavity through the hole of the valve core and then ejects the liquid through the nozzle. When the compression handle is released, the volume in the spring cavity increases, and negative pressure is formed. The ball opens under negative pressure, and the liquid in the bottle enters the spring cavity. At this time, a certain amount of liquid has been stored in the valve body. When the handle is pressed again, the liquid stored in the valve body will be flushed upwards and sprayed out through the nozzle.

      From the above working principle, the key to a good pump head is to pay special attention to the following aspects:

      1. Glass ball or steel ball under the spring.

      2. Check the sealing ring on the upper end of the valve body.

      3. The matching of compression handle and valve core.

      4. The design of the nozzle depends on the atomization effect.

      Therefore, the general function of the pump head also detects these four positions and routinely detects other appearance and coordination issues.
