  • Electrostatic spraying device
    Patent number: 7823809
    Abstract: An electrostatic spraying device has a capability of confirming that the device is ready for making an electrostatic spraying of the liquid composition on a user's skin. The device includes a nozzle and a pump for dispensing the liquid composition out through the nozzle. An emitter electrode is disposed to electrostatically charge the liquid composition being dispensed for making the electrostatic spraying. The device is provided with a power switch and a selector for selection between a spraying mode and a dripping mode. In the dripping mode, the pump is alone actuated to dispense the liquid composition absent electrostatic charge. In the spraying mode, both of the pump and the emitter electrode are activated to make the electrostatic spraying. Thus, the user can be easy to drip the liquid composition by simply manipulating the selector prior to initiating the electrostatic spraying.
