A microdosing device with a dosing chamber for the at least temporary reception of a liquid quantity, and with which is associated at least one discharge opening is provided. A vibrating unit in operative connection with at least one boundary surface of the dosing chamber is provided in order to vibrate the same for a discharge process, and with a delivery function unit connected to the vibrating unit for activating the latter during a delivery time period. A drying function unit is additionally provided and can be activated in time-separated manner with respect to the delivery function unit in order to free the dosing chamber from liquid residues.

Microdosing device

A metering device for dispensing a medium to an environment is provided. The metering device includes a housing, a shallow metering chamber within the housing which is of planar design and is essentially closed off from the environment by wall sections, a first media inlet which is connected to the metering chamber and can be connected to a media reservoir, and a vibration mechanism which is arranged in such a manner that vibrations generated by the vibration mechanism cause pulsing changes in volume of an internal volume of the metering chamber. A wall section which is designed as an outlet wall section has metering openings so that the metering chamber is connected to the environment. The vibration mechanism forms a vibration wall section so that the metering chamber is delimited.

Metering device

A dosing device with an electromechanical interface is provided. The dosing device includes delivery means, a medium reservoir and an applicator, on the one hand, and a control unit and electrical energy store, on the other hand, in separate structural units. Guide means are provided for fitting one of the structural units into the other structural unit. The guide means has an electromechanical interface for coupling and/or uncoupling relative to the control unit and/or energy store without using tools.

Dosing device

A microdosing device includes a dosing chamber which at least temporarily receives a quantity of liquid, and to which at least one dispensing opening is assigned. A vibration unit is operatively connected to at least one boundary surface of the dosing chamber in order to cause this boundary surface to oscillate for the purpose of a dispensing operation. At least two admission channels spaced apart from one another are provided on the dosing chamber.
