LOTION PUMP
Document Type and Number:
WIPO Patent Application WO/2020/140513
Kind Code:
A1
Abstract:
Disclosed is a lotion pump (100, 200, 300, 400, 500, 700), comprising a movable part and a fixed part. A switching mechanism is formed on the movable part and the fixed part, and as the movable part rotates or moves up and down, an elastic reset mechanism of the lotion pump (100, 200, 300, 400, 500, 700) can be switched between a standby state and a non-standby state by means of the switching mechanism. The structure of the lotion pump (100, 200, 300, 400, 500, 700) can prevent a spring (140, 240, 340, 440, 750) from yield deformation caused by long-term compression, and can also realize the form where a lock head is at a lower position.
