Abstract

The invention discloses a built-out spring universal spray pump. The built-out spring universal spray pump comprises a lock bottle cap. The built-out spring universal spray pump is characterized in that a pump body installation part is arranged at the upper end of the lock bottle cap, and a pump body assembly is arranged in the pump body installation part; the lower end of the pump body assembly is provided with a liquid inlet, and a pump bead capable of sealing the liquid inlet is arranged in the liquid inlet; the liquid inlet is connected with a universal liquid inlet connector, and a button is connected with the upper end of the pump body assembly; a liquid spray channel is formed in the button, and a spray point is arranged on the button and communicated with the liquid spray channel. Through the built-out spring universal spray pump, the purpose that the defects in the prior art are overcome is achieved. The stable-type built-out spring universal spray pump is simple in structure, convenient to use and capable of achieving the self-locking function by rotating a curved nozzle. In addition, a reset spring does not make contact with liquid.

Description

technical field

[0001] The invention relates to an external spring universal spray pump. Background technique

[0002] Due to its exquisite design and convenient use, the spray pump has been widely used in daily chemical and pharmaceutical industries. The existing spray pump has a relatively complex structure, and the curved nozzle 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 spray pump generally all is 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 defects in the existing design of the existing spra...
