Definitions

  • the present invention relates to a dispenser for liquid disinfectants, liquid surfactant products such as liquid soap, hand lotion, shower gel, care shampoo for hair, or for other liquids with at least one storage container and at least one liquid outlet opening, with at least one between the storage container or containers (n ) and the respective liquid outlet opening, which pressurize the liquid with the pump unit, and furthermore with a housing part which accommodates at least the storage container or containers, the dispenser being designed as a structural unit which can be inserted into a wall installation opening.

Then an electr jumps over a proximity switch. Drive of the metering pump and causes a single or multiple dispensing of a metered amount of soap.
  • the dispenser requires an electrical voltage connection at the installation site. This and the electronics used in the dispenser must be particularly protected against moisture to avoid a short circuit and a possible fire of the device. Such a dispenser must therefore be placed at a sufficient distance from taps.
