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： Disclosed is a lotion pump comprising: a pressing head (10) comprising a pressing head body (11); a cylinder (30); a cylinder head connected to an upper end of the cylinder and having an inner hole; a threaded sleeve (20) connected to the cylinder head; and a piston rod (40), with one end being connected to the pressing head body, and the other end extending into the cylinder and being provided with a piston (50). The lotion pump further comprises a neck sleeve (13) formed on the pressing head body. A first slope is formed on a lower portion of the neck sleeve, and a second slope matching the first slope is formed on the top of the threaded sleeve. The lotion pump having the foregoing structure can ensure the sealing against the outside when the lotion pump is in a standby state or an upper locked state, so as to prevent water from seeping into the lotion pump during bathing.

摘要： A pressing pump, comprising a pressing head, a tooth sleeve and an air cylinder, wherein the tooth sleeve is connected together with the air cylinder, a piston rod is connected below the pressing head, and a piston is mounted on the piston rod, and the part of the piston rod comprising the piston extends into the interior of the air cylinder. The side peripheral wall of the pressing head cooperates with the side peripheral wall of the tooth sleeve to form a reset mechanism accommodating chamber. The reset mechanism accommodating chamber accommodates an elastic reset mechanism, and the elastic reset mechanism is supported between the pressing head and the tooth sleeve and is arranged around the piston rod.

摘要： A bladder-type dispensing pump (100) comprises a push nozzle (110) and a container cap (120), said nozzle (110) and cap (120) being interconnected. The push nozzle (110) is provided with a bladder portion (111). The bladder portion (111) is able to deform such that the volume of the internal cavity thereof may change. The bladder-type dispensing pump (100) is further provided with an elastic return mechanism. A portion of the elastic return mechanism is connected to or in contact with the bladder portion (111). When the bladder portion (111) is depressed so as to deform, the elastic return mechanism deforms with it, and when pressure acting on the bladder portion (111) is removed, the elastic return mechanism returns to its non-deformed state, causing the bladder portion (111) to reset.

摘要： 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.
