摘要： A pumping device (100), comprising a movable part and a fixed part. The movable part is capable of reciprocating relative to the fixed part, thereby dispensing, by means of a straw (30) connected to the fixed part, a product contained in a container (20). The pumping device (100) comprises elastic members (150, 250, 350, 550, 650, 850, 950, 1050), one end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the movable part, and the other end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the container (20), or is supported on the container (20) by means of the fixed part. The pumping device (100) having the described structure allows the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) to be fabricated using plastic, and is also capable of obtaining the required elasticity.

摘要： The present invention relates to a press-type liquid pump. The liquid pump comprises a fixed unit fixed relative to a container and a movable unit capable of performing a reciprocating motion relative to the fixed unit, and a liquid product is pumped to the exterior of the container. The reciprocating motion is achieved by a pressing force applied by a user to the movable unit to move the movable unit relative to the fixed unit in combination with an elastic restoring means for restoring the movable unit relative to the fixed unit after the pressing force is removed. The elastic restoring means is a plastic elastic compressing means located below a toothed sleeve and installed between the fixed unit and the movable unit, which comprises at least one elastic strip generally formed in an arc shape.

摘要： 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.

摘要： Disclosed is a liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900), including 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.
