First, understand the lotion pump
The emulsion pump uses the principle of atmospheric balance to pump out the raw material liquid in the bottle by pushing, and replenish the external atmosphere to the liquid distributor in the bottle. The main performance indicators of the emulsion pump: air pressure times, pump displacement, low pressure , nozzle opening torque, rebound speed, water intake index, etc.
The size of the pump head is determined by the caliber that matches the bottle body. The spray specification is 12.5mm-24mm, and the water output is 0.1ml/time-0.2ml/time. It is generally used for the packaging of perfume, gel water and other products. The caliber is the same, and the handover The length of the bottle can be determined by the height of the bottle.
The specifications of the lotion pump range from 16ml to 38ml, and the water output is 0.28ml/time - 3.1ml/time. It is generally used for cream and washing products.
Special dispensers, such as foam pump head and hand pump head, foam pump head is a kind of non-inflatable hand pump head, it does not need to be inflated to generate foam, it can produce quantitative, high-quality foam by just pressing lightly, generally There are dedicated bottles, and the clasp spray is usually used for products such as detergents.
The structure of the distributor is very complex, generally including dust cover, percussion head, percussion rod, gasket, piston, spring, valve, cover, pump body, suction pipe, valve ball (steel ball, glass ball), cover, anti- The dust cover can be colored, electroplated, or inlaid with anodized aluminum.
Vacuum bottles are usually cylindrical, with specifications ranging from 15ml to 50ml, each with 100ml, and the overall capacity is small. Relying on the principle of atmospheric pressure, it can avoid the pollution in the use of cosmetics. The vacuum bottle has electrolytic aluminum, plastic electroplating and colored plastic, and the price is higher than other ordinary containers. High, ordinary orders are not high, customers rarely open their own molds, they need a lot of molds, and the cost is very high.
Second, the working principle of the lotion pump head:
Press the handle by hand, the volume of the spring chamber decreases, the pressure rises, the liquid enters the nozzle chamber through the hole of the valve body, and the liquid is sprayed out through the nozzle. At this time, after the handle is released, the volume of the spring chamber increases, forming a negative pressure. The ball is opened under the action of negative pressure, and the liquid in the bottle enters the spring chamber. At this time, there is a certain amount of liquid in the valve body. When the handle is pressed again, the liquid stored in the valve body is ejected upward.
From the above working principle, the key to a good lotion pump head is to pay special attention to the following aspects:
1. Glass beads or steel balls under the spring, the sealing here is very important, which is related to the upward force of the liquid in the spring chamber. If it leaks from here, part of the liquid will leak into the bottle when the handle is pressed, thus affecting the spray of the liquid. produce effect;
2. If there is leakage in the sealing ring on the upper end of the valve body of the lotion pump, the upward force of the liquid to pull up when leaving the handle will be reduced, and the amount of liquid stored in the valve body will be small, which will also affect the spray effect.
3. The lever of the lotion pump is engaged with the valve body. If the engagement here is loose, there will be leakage. When the liquid rises to the nozzle, there will be a certain resistance, which will cause the liquid to flow backward. If it leaks from here, it will also affect the spray effect.
