The    Lotion Pump   , also called the push-type lotion pump, is a liquid dispenser that uses the principle of atmospheric balance to pump out the liquid in the bottle and fill the outside atmosphere into the bottle. The main performance indicators of the lotion pump: air pressure times, pumping amount, down pressure, head opening torque, rebound speed, water intake index and so on.

The dispenser is divided into two types: the tie type and the screw type. From the function, it is divided into spray, foundation cream, lotion pump, aerosol valve, vacuum bottle.

  
 The size of the pump head is determined by the diameter of the matching bottle. The spray size is 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time. It is generally used on the packaging of perfume, gel water and other products. The length can be determined according to the height of the bottle.

   
The size range of the emulsion pump head is 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-held nozzles, the non-inflated hand pump head, does not require gas to create foam, and can be used to produce quantitative high quality foam with a light press. Usually equipped with a special bottle. Hand-held sprinklers are commonly used on products such as detergents.

   
The composition of the dispenser is relatively complicated, generally including: dust cover, hoe, mast, gasket, piston, spring, valve, bottle cap, pump body, straw, valve ball (with steel ball, glass ball). The cap and dust cover can be colored, electroplated, and can be set with an electric aluminum ring.

Second, the working principle of the pump head:

     
 Manually press the pressing handle downward, the volume in the spring chamber is reduced, the pressure is increased, the liquid enters the nozzle cavity through the hole of the valve core, and then the liquid is ejected outward through the nozzle. At this time, the pressing handle is released, and the spring cavity is released. The volume increases, a negative pressure is formed, the sphere opens under the action of negative pressure, and the liquid in the bottle enters the spring chamber. At this time, there is already a certain liquid in the valve body, and the liquid stored in the valve body when the handle is pressed again Rush up and spray through the nozzle;

     
 A good pump head is especially important in the following places:

     
 1. The glass beads or steel balls under the spring, the sealing here is very important, which is related to the strength of the liquid in the spring cavity. If it leaks here, when the pressure is pressed, some of the liquid will leak into the bottle. And affect the effect of liquid spray;

    
 2. It is the sealing ring at the upper end of the valve body. If it leaks here, the force of the liquid pumping up when the pressure handle is released is reduced, and the amount of liquid stored in the valve body is small, which also affects the spray effect;

     
3. The cooperation between the pressure handle and the valve core. If the mixture is loose and leaking, there will be a certain resistance when the liquid rushes up to the nozzle. The liquid will flow back. If it leaks here, it will also affect the spray effect. ;

     
4. The design of the nozzle, the design of the nozzle is directly related to the effect of the spray. See the next page for details on the nozzle design.

   
Therefore, the function of the general pump head also detects these four positions, and other appearances and problems in coordination are detected by routine;
