Adjustable Outside Spring Lotion Pump

The adjustable outside spring lotion pump consists of a pump head, an external spring system, an air extraction tube, a sealing ring, an adjustment ring, and an external push button. Compared with the traditional internal spring, the biggest advantage of the external spring is that the spring can be placed outside the pump, reducing the space occupied by the inner cavity of the pump body. Setting the spring on the outside, simplifies the internal structure and improves the appearance design of the pump body, making it look more modern and high-end. The design of the external spring also reduces the complexity of the pump head, making it easier to clean and maintain. It has a strong sealing performance and can effectively prevent liquid leakage during storage and use. The multiple sealing rings and anti-leakage mechanism in the sealing system ensure that the lotion pump can maintain its sealing during long-term storage and use, preventing the product from being contaminated or wasted.
