1. 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.
