Universal lotion pump with outside mounted spring

Abstract

The invention discloses a universal lotion pump with an outside mounted spring. The universal lotion pump comprises a locking bottle cap, wherein a pump body mounting part is arranged at the upper end of the locking bottle cap; a pump body component is arranged in the pump body mounting part; a liquid inlet is formed in the lower end of the pump body component; a pump ball capable of sealing the liquid inlet is arranged in the liquid inlet; a universal liquid inlet joint is connected onto the liquid inlet; a button is connected to the upper end of the pump body component; the universal liquid inlet joint comprises a universal joint seat; a first liquid priming channel penetrating through the axial direction of the universal joint seat is arranged in the universal joint seat; a second liquid priming channel is arranged on side wall of the universal joint seat and mutually communicates with the first liquid priming channel; a pump ball capable of sealing the second liquid priming channel is arranged in the second liquid priming channel; and an elastic part for preventing the pump ball from sliding out is arranged at the inlet end of the second liquid priming channel. The universal lotion pump is simple in structure and convenient in use; and the aims that the spring is self-locked and a return spring is not in contact with liquid can be achieved by rotating a bib.

Description

technical field [0001] The invention relates to a spring external universal lotion pump. Background technique [0002] Because of its exquisite design and convenient use, the lotion pump has been widely used in daily chemical and pharmaceutical industries. The existing lotion pump has a relatively complicated structure, and the curved mouth is generally in an active state after use. If it is pressed by mistake, unnecessary troubles may occur. In order to solve this problem, the existing method is to provide an additional outer cover on the spray cover, but the existing method not only increases the production cost, but also the outer cover is easy to fall on the ground during use, which is inconvenient to use. And the back-moving spring of existing lotion pump is generally all arranged in the pump chamber, contacts with the liquid in the pump chamber, can cause pollution to liquid like this, unhygienic.

AI Technical Summary

Problems solved by technology

It is currently used for lotion pumps, its structure is relatively complicated, and the curved mouth is generally in an active state after use. If you press it by mistake, unnecessary troubles may occur

In order to solve this problem, the existing method is to set an additional outer cover on the spray cover, but the existing method not only increases the production cost, but also the outer cover is easy to fall on the ground during use, which is inconvenient to use

And the back-moving spring of existing lotion pump is generally all arranged in the pump chamber, contacts with the liquid in the pump chamber, can cause pollution to liquid like this, unhygienic

[0003] In addition, due to the defects in the existing design of the existing lotion pump, the liquid inlet pipe must be at a certain position or angle to enter the liquid, which seriously affects the use effect
