Abstract

The present invention relates to a supraparticle atomizing device and, more specifically, to a supraparticle atomizing device having an inner plate provided at the upper part of an ultrasonic vibrator inside a housing and having a circulation passage formed at the circumference of the inner plate of the inside of the housing by using the rapid flow rate of the air to be ventilated to the inside of the housing through a blower, and thus only liquid microparticles generated at the lower region of the inner plate by the ultrasonic vibrator are pulled up to the upper region thereof, thereby allowing the liquid microparticles to be atomized through an atomizing hole and allowing the liquid microparticles to be rapidly diffused into the air with rapid ventilation air.

Claims

1. An apparatus for superparticle spraying comprising:

a housing forming an air inlet at one side of the housing and accommodating a liquid therein;

an ultrasonic vibrator being installed at the housing and generating fine liquid particles by vibrating the liquid;

a blower carrying the air inside the housing through the air inlet;

an inner plate being disposed at a predetermined distance from upper of the ultrasonic vibrator inside of the housing, and forming a circulation passage to circulate the fine liquid particles by using the flow rate of the air which is blown into the inside of the housing through the blower, the circulation passage being defined around the inner plate with the housing; and

a spray nozzle being forming on the housing and atomizing the fine liquid particles which circulates from the lower area of the inner plate to the upper area of the inner plate outside the housing through the circulation passage.

2. The apparatus of claim 1, further comprising:

a guide plate being disposed between the air inlet and the inner plate and guiding air introduced into the air inlet to the upper area of the circulation passage.

3. The apparatus of claim 1, wherein the air inlet is formed on one side of the housing facing one longitudinal end of the inner plate, and the guide plate are installed at an angle between the air inlet and the inner plate so that the air is blown into the housing through the blower to generate a venturi effect with respect to the circulation passage.

4. The apparatus of claim 3, wherein the lower end of the guide plate is connected to the lower end of the air inlet and the upper end is disposed at a predetermined distance upward from the one end of the inner plate.

5. The apparatus of claim 1, wherein a plurality of ultrasonic transducers are provided on a bottom plate inside the housing at a predetermined distance between therein, and the inner plate is disposed parallel the a bottom plate inside the housing, and a length of the inner plate is greater than the sum of length of two ultrasonic transducers at both ends of the plurality of the ultrasonic transducers.

6. The apparatus of claim 1, further comprising:

a blocking plate preventing diffusion of water droplets from the liquid as well as controlling by the cross-sectional area of the circulation passage.

7. The apparatus of claim 1, wherein the inflow port is formed on the upper side of the housing opposite to the air inlet, and a discharge duct having a predetermined height is installed on the inflow port.

8. The apparatus of claim 7, wherein an inclined surface portion inclined downward from an edge is formed on an upper end of the discharge duct.

9. The apparatus of claim 7, wherein a cross-sectional area of the air inlet and a cross-sectional area of the atomizer are formed identically.

10. The apparatus of claim 1, wherein a liquid reservoir for storing liquid to be supplied to the inside of the housing is provided at one side of the housing, and a liquid supply device for supplying the liquid to the inside of the reactor is provided.

11. The apparatus of claim 10, wherein the liquid supply device comprises a first hose connected to the inside of the housing, and a second hose connected to the inside of the liquid reservoir, and a water pump connected to the first hose and the second hose.

12. The apparatus of claim 10, wherein the housing comprises a water level sensing means for sensing the liquid level inside the housing, and the liquid supply device is selectively operated according to the liquid level.
