Abstract
The invention relates to an electrostatic atomizer for liquids, in particular, cosmetics, the atomizer comprising a housing, an electrical energy source, an activation mechanism, control electronics, a high-voltage source, a liquid tank, a delivery device and atomizer nozzles. The delivery device is arranged here between the liquid tank and the atomizer nozzles, the delivery device being connected to the liquid tank by a first line and the delivery device being connected to the atomizer nozzles by a second line, so that the delivery device sucks liquid out of the liquid tank and delivers it to the atomizer nozzles.
Claims23
An electrostatic liquid atomizer comprising:
- a housing;
- an electrical energy source;
- an activation mechanism comprising an activation button;
- control electronics;
- a voltage source having a pair of opposite poles;
- a liquid tank;
- a delivery device comprising a multiple hose pump;
- atomizer nozzles;
- and
- a switch that changes a rotation direction of a rotor of the hose pump between a delivery mode and a return mode,
- wherein the activation mechanism further comprises electrical contacts to open and/or close a circuit between the activation mechanism and the control electronics,
- wherein the delivery device is arranged between the liquid tank and the atomizer nozzles,
- wherein the delivery device is connected to the liquid tank by a first line,
- wherein the delivery device is connected to the atomizer nozzles by a second line, so that the delivery device sucks liquid out of the liquid tank and delivers the liquid to the atomizer nozzles,
- wherein during a pumping operation, the house pump performs in a rolling manner, thereby completely pinching a portion of a delivery hose arranged between the first line and the second line,
- wherein the delivery device and the voltage source are activated by the activation mechanism, and wherein an actuating element of the activation button of the activating mechanism is constructed as a ground contact connected to one pole of the voltage source so as to have an opposite electrical polarity with respect to an electrical polarity of the atomizer nozzles,
- wherein the first line, the second line and the delivery hose are integrally formed as an extruded plastic connecting hose, and
- wherein the first line and the second line each comprise a number of hoses arranged in parallel and integrally formed continuously in one piece, and for each atomizer nozzle, a respective one of the number of hoses leads from the nozzle through the multiple hose pump of the delivery device to the liquid tank.
