Hereinafter, the technical configuration of the electrostatic atomizer and the electrostatic atomizer according to the accompanying drawings will be described in detail.

FIG. 5 is a schematic view of an electrostatic atomizing apparatus according to an embodiment of the present invention, and FIG. 6 is a schematic view of a nozzle unit of an electrostatic atomizing apparatus according to an embodiment of the present invention.

5 and 6, an electrostatic atomizer 100 according to an embodiment of the present invention mainly includes a nozzle unit 120, a pumping unit 130, a fluid container 140, a blower (not shown) 110 and a control unit 150.

The nozzle unit 120 includes a nozzle 121 and an electrode unit. The nozzle 121 is configured to spray mist droplets in a single direction with a fluid supplied thereto, and the fluid is composed of water or lotion (hereinafter referred to as "water").

The electrode unit includes a first electrode 122 and a second electrode 124. The first electrode 122 is applied with a voltage so that the fluid supplied to the nozzle 121 is electrostatically sprayed. The first electrode 122 functions as a main electrode and forms water mist droplets in the form of fine particles to electrostatically spray water supplied to the nozzles 121. The second electrode 124 functions as an auxiliary electrode and is disposed on the downstream side in the flow direction of the droplet sprayed from the nozzle 121 and is disposed in parallel with the first electrode 122.

A droplet sprayed from the nozzle 121 is temporarily trapped between the first electrode 122 and the second electrode 124. [ That is, when a voltage is applied to the first electrode 122, mist droplets are sprayed from the nozzle 121, and the sprayed droplets are sprayed to the second electrode 124 and the first electrode 122). ≪ / RTI > The captured droplet is blown into the passenger compartment together with the air blown from the blower 110. Therefore, as the liquid droplets temporarily trapped between the first electrode 122 and the second electrode 124 are sufficiently mixed with the air blown from the blower 110 and sprayed into the vehicle interior, It is possible to reach the entire area evenly and sufficiently.

The pumping unit 130 functions to pump the water accommodated in the fluid container 140 to the nozzle 121 to supply water to the nozzle 121. The fluid container 140 receives water and can be configured to be openable or closable to receive water from the outside or to connect a separate pipe. The fluid container 140 and the nozzle 121 are connected through a supply pipe 123 and the water contained in the fluid container 140 is transferred to the nozzle 121 through the supply pipe 123. The pumping unit 130 may be installed on the supply pipe 123.

The blower 110 functions to blow mist droplets generated in the nozzle 121 to the interior of the vehicle. The blower 110 may use a blower of the automotive air conditioner, and may be installed separately from the blower of the air conditioner. The control unit 150 controls the amount of voltage applied to the first electrode 122 and the operation ON / OFF of the first electrode 122 and turns on / off the pumping unit 130 and ON / OFF control of the blower 110.

If the occupant of the winter vehicle is exposed to hot wind for a long time, the skin such as the face and hands may be dried, causing respiratory diseases, and the safety operation may be hindered. It is possible to prevent the respiratory diseases and prevent the skin from drying. In this case, the nozzle unit 120 according to an embodiment of the present invention is configured such that, as compared with a conventional humidifying structure using water vapor, a mist sprayed with a small amount of charged water and a charged mist is sprayed into the interior of the vehicle, The mist is reacted only to the skin of the human body while minimizing the influence of the surroundings, such as putting it on the skin or hurting the electronic equipment, thereby performing localized humidification on the exposed skin.

In particular, when the power is turned on, the upper control unit 150 turns on the pumping unit 130, turns on the blower 110, and then turns on the voltage application of the nozzle unit 121 Respectively. That is, when the power supply of the electrostatic atomizing apparatus is turned on, a sequence is configured so that the operation of each component is sequentially operated at intervals of time. For example, when the power is turned on, a voltage may be applied to the nozzle 121 after a lapse of about 3 seconds after the blower 110 is turned on.

Therefore, the droplet remaining in the nozzle 121 is completely dried by the operation of the blower 110, and a voltage is applied to the electrode portion to spray mist droplets from the nozzle 121. Therefore, Can be prevented from dropping into the vehicle interior.

The control unit 150 may be configured to turn off the pumping unit 130 and turn off the voltage of the nozzle unit 121 and turn off the blower 110 when the power is turned off, Respectively. That is, when the power supply of the electrostatic atomizing apparatus is turned off, a sequence is configured so that the operation of each component is sequentially operated at intervals of time. For example, when the power is turned off, after about 5 seconds have elapsed from turning OFF the pumping unit 130, the voltage applied to the nozzle 121 is turned OFF. Accordingly, after the pumping unit 130 is turned off, a voltage is applied to the nozzle 121 for about 5 seconds, so that droplets remaining on the nozzle 121 can be completely dried. As a result, it is possible to solve the problem that droplets remaining on the nozzle 121 fall into the interior of the vehicle.

7 is a flowchart of an electrostatic atomization method according to an embodiment of the present invention.

7, the electrostatic atomizing method according to an embodiment of the present invention includes a step ST-10 of turning on the pumping unit 130, a step ST-20 of turning on the blower 110, A step ST-30 of turning on the voltage application of the nozzle unit 121, a step ST-40 of turning off the pumping unit 130, and a step of turning off the voltage application of the nozzle unit 121 (ST-50) and turning off the blower 110 (ST-60).

Therefore, when the apparatus is powered on, droplets remaining on the nozzle 121 are completely dried by the operation of the blower 110, and then a voltage is applied to the electrode portion to spray mist droplets from the nozzle 121, It is possible to solve the problem that droplets remaining in the previous nozzle 121 fall into the interior of the vehicle.

In addition, when the apparatus is turned off, a voltage is applied to the nozzle 121 for a predetermined period of time after the pumping unit 130 is turned off, so that droplets remaining on the nozzle 121 can be completely dried. As a result, it is possible to solve the problem that droplets remaining on the nozzle 121 fall into the interior of the vehicle.
