Self-cleaning liquid dispenser

摘要

A self-cleaning liquid dispenser, for example for liquid soap or disinfectants, having a valve which is under spring pressure and opens by pressure of the hand, in which the valve cylinder mounted on a container has an inner shoulder which lies between the valve piston under the pressure of a spring and a cleaning piston connected to said valve piston by a connecting rod, the valve piston being fastened on a slide rod. In the dispenser, the valve outlet tube and the nozzle are cleaned after each actuation so that stickiness due to residues dispensed can no longer occur. Additionally, the container and the valve pump form a unit in which the replacement of liquid for the dispenser is extremely simplified.
