Abstract:
A lotion pump comprises a pump body (1). The pump body (1) is provided with a pump chamber (2). A bottle locking cap (3) for fixing the pump body (1) to a bottle is connected to the pump body (1). A pumping assembly (4) for pumping a lotion in a bottle up by moving up and down in the pump chamber (2) is provided in the pump chamber (2). A one-way valve (5) for the lotion in the bottle to be merely discharged upwards when the pumping assembly (4) operates is provided on the lower end of the pump chamber (2). A bent nozzle (6) for the lotion to be discharged is connected to the upper end of the pumping assembly (4). The bent nozzle (6) is provided with a connection ring (7). A locking part (8) which can be rotatably connected to the connection ring (7) is provided on the upper end of the pump body (1). An anti-slip structure for preventing the connection ring (7) from driving the bent nozzle (6) to rotate inadvertently when the locking part (8) and the connection ring (7) are connected is provided between the locking part (8) and the connection ring (7). The lotion pump features a simple structure and low costs, and can prevent inadvertent opening due to the rotation of the bent nozzle during a transportation process.
