Special dispensers such as lotion pump heads and hand buckle sprinklers. The foam pump head is a non-irritating manual pressure pump head. It does not need to inject air to generate foam. Just a light press will produce quantitative and high-quality foam. Usually comes with a special bottle. Hand button nozzles are usually used for detergents and other products. Below, Mini Trigger Sprayer Manufacturers introduces the precautions for the use of lotion pump heads:
1. The glass ball or steel ball under the spring, the sealing is very important. It is related to the upward force of the liquid in the spring cavity. If it leaks here, the liquid will leak into the bottle when the handle is pressed, which will affect the effect of the liquid spray.
2. The sealing strip on the top of the valve. If it leaks here, the bottom of the liquid pulling force when the handle is loosened will be reduced, and the amount of liquid stored in the valve body will be small, which will also affect the spray effect.
3. If there is a loose leak between the pressure bag and the core of the valve, there may be a certain resistance when the liquid hits the nozzle, and the liquid will flow back. If it leaks here, it will also affect the spray effect.
4. The design of the nozzle, design of the nozzle is directly related to the spray effect. Therefore, the function of the ordinary pump head can also detect these four positions, and other shapes and matching problems are routinely detected.
