Dosing 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.
1. A dosing device for dosing a medium, said dosing device comprising:
a first structural unit including an electrically driven delivery device, a plug-in portion enclosing therein a reservoir for storing medium to be dosed, and an applicator for dispensing the medium, the delivery device being configured to receive electrical energy required to deliver medium to the applicator;
a second structural unit including a control unit for actuating said delivery device, and an electrical energy store for electrically powering said control unit and said delivery device, said second structural unit defining therein a receiving chamber which opens through an end of said second structural unit and is configured to house said plug-in portion of said first structural unit, said first and second structural units being wholly separable from one another;
a guide arrangement cooperating between said first and second structural units to permit the coupling of said first and second structural units to one another; and
an electrical interface cooperating between said first and second structural units and disposed to electrically couple said delivery device of said first structural unit to said energy store and said control unit of said second structural unit without the use of tools, said electrical interface being disposed and configured to supply electrical energy directly to said delivery device and said delivery device receiving electrical energy from said energy store via said electrical interface to thereby power and operate said delivery device upon coupling of said first and second structural units to one another.
2. The dosing device according to claim 1 , wherein said guide arrangement includes a linear guide disposed on said plug-in portion and a linear guide disposed in said receiving chamber, said linear guides being configured to cooperate with one another during coupling of said first structural unit to, and during uncoupling of said first structural unit from, said second structural unit.
3. The dosing device according to claim 1 , wherein said electrical interface includes an electrical contact disposed on said plug-in portion and electrically connected to said delivery device, and an electrical contact disposed in said receiving chamber and electrically connected to said control unit, said electrical contacts being disposed to electrically contact one another upon insertion of said plug-in portion into said receiving chamber.
4. The dosing device according to claim 1 , wherein the receiving chamber surrounds the reservoir.
