Abstract: A lotion pump includes a movable portion and a stationary portion. A shifting mechanism is formed on the movable portion and the stationary portion, which shifts the elastic restoring mechanism of the lotion pump between a standby state and a non-standby state as the movable portion rotates or moves up and down. The structure of the lotion pump can prevent the spring from yielding due to compressed for a long time, while can also realize a form of locking at lower position.

Abstract: Disclosed is a liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900), comprising a movable unit and a fixed unit. The movable unit is capable of moving relative to the fixed unit so as to pump a product out. An elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is provided between the movable unit and the fixed unit, and the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) comprises at least one elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931). The elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) applies a biasing force to the movable unit to restore the movable unit after the product is pumped. The liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900) further comprises an elastic mechanism adjusting member movable between a first position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a relaxed state, and a second position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a preloaded state. With the provision of the elastic mechanism adjusting member, it is convenient to press down a pressing head (110, 210, 310, 410, 510, 610, 710, 910) during use, and the yielding deformation of the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) due to long-term stress can also be avoided.

Abstract: The invention provides a water-ingress-preventing mechanism for a lotion pump. The mechanism is mainly used for a lotion pump mounted on a container with a liquid therein and is able to effectively prevent foreign liquids from entering the container. According to one aspect of the invention, in the locking tube portion (13) of the press head (10) is formed at least one longitudinal slot (15) which extends upwards from the lower end edge of the locking tube portion over at least part of the length of the locking tube portion. The slot is disposed such that the upper end of the slot is at a position above the top surface (25) of the cylinder cover (20) when the press head is pressed down to and at the lower stop position of its press stroke with respect to the cylinder cover. According to another aspect of the invention, the external thread (14) on the locking tube portion extends helically upwards from the lower end edge of the locking tube portion, whereas the internal thread (26) in the central through-hole (21) in the cylinder cover extends helically downwards from the upper end edge of the central through-hole. The features in the both of the two aspects effectively prevent foreign liquids from being sucked into the container during operation of the lotion pump.
