Abstract

Provided is a hybrid spray pump which sprays and applies a viscous liquid in a fine particle state to a material. The hybrid spray pump sprays effectively fine particles of the viscous liquid according to various characteristics of the viscous liquid ranging from low to high viscosity, and improves the quality of a particle application process by mixing fine particles and aerosol particles by spraying.

First claim

What is claimed is:

1. A hybrid spray pump comprising: a chamber in which a viscous liquid is stored;
a vibrator installed in the chamber generating an aerosol by transmitting vibration to the viscous liquid inside the chamber atomizing the viscous liquid;
a sprayer installed inside the chamber to mix the viscous liquid inside the chamber and a compressed gas and spray the viscous liquid in a sprayed state;
a mixing pipe connected to the chamber to transfer, to an outside, particles of the viscous liquid in the aerosol state and the viscous liquid in the sprayed state inside the chamber, wherein the particles of the viscous liquid in the aerosol state and the viscous liquid in the sprayed state are mixed in the mixing pipe; and
a nozzle which is connected to the mixing pipe and through which the particles of the viscous liquid are sprayed, wherein the particles of the viscous liquid in the aerosol state are smaller than the particles of the viscous liquid in the sprayed state.

2. The hybrid spray pump of claim 1 , wherein the sprayer comprises a spray gas supply pipe to which the compressed gas is supplied, a liquid supply pipe to be submerged in the viscous liquid to transmit the viscous liquid to the spray gas supply pipe, and a spray pipe through which the viscous liquid in the sprayed state formed when the compressed gas supplied through the spray gas supply pipe meets the liquid supply pipe is sprayed into the chamber.

3. The hybrid spray pump of claim 2 , further comprising
a sheath nozzle installed in the nozzle to wrap around an outer periphery of the nozzle and spray a compressed gas into an outer periphery of the particles of the viscous liquid sprayed from the nozzle.

4. The hybrid spray pump of claim 2 , further comprising
a spray gas valve installed in the spray gas supply pipe to adjust a flow rate
a mixing valve installed in the mixing pipe to adjust a flow rate, and
a control unit for controlling an operation of each of the vibrator, the spray gas valve, and the mixing valve.

5. The hybrid spray pump of claim 4 , further comprising
a chamber gas supply pipe connected to the chamber and supplying a gas into the chamber, and
a chamber gas valve installed in the chamber gas supply pipe to adjust a flow rate, wherein
the control unit controls an operation of the chamber gas valve.

6. The hybrid spray pump of claim 5 , further comprising a virtual impactor installed in the mixing pipe.

7. The hybrid spray pump of claim 3 , further comprising
a spray gas valve installed in the spray gas supply pipe to adjust a flow rate,
a mixing valve installed in the mixing pipe to adjust a flow rate,
a sheath valve installed in the sheath nozzle to adjust a flow rate of the compressed gas flowing via the sheath nozzle, and
a control unit for controlling an operation of each of the vibrator, the spray gas valve, the mixing valve, and the sheath valve.

8. A hybrid spray pump comprising:
an aerosol chamber in which a viscous liquid is stored;
a vibrator installed in the aerosol chamber generating an aerosol by transmitting vibration to the viscous liquid inside the aerosol chamber atomizing the viscous liquid;
a spray chamber in which a viscous liquid is stored;
a sprayer installed inside the spray chamber to mix the viscous liquid inside the spray chamber and a compressed gas and spray the viscous liquid in a sprayed state;
a mixing pipe connected to each of the aerosol chamber and the spray chamber to mix and transfer, to an outside, the viscous liquid in the aerosol state inside the aerosol chamber and the viscous liquid in the sprayed state inside the spray chamber, wherein the mixing pipe is connected between the sprayer chamber and the nozzle and is connected between the aerosol chamber and the nozzle; and
a nozzle which is connected to the mixing pipe and through which particles of the viscous liquid are sprayed, wherein the particles of the viscous liquid in the aerosol state in the aerosol chamber are smaller than the particles of the viscous liquid in the sprayed state in the spray chamber.

9. The hybrid spray pump of claim 8 , wherein the sprayer comprises a spray gas supply pipe to which the compressed gas is supplied, a liquid supply pipe to be submerged in the viscous liquid to transmit the viscous liquid to the spray gas supply pipe, and a spray pipe through which the viscous liquid in the sprayed state formed when the compressed gas supplied through the spray gas supply pipe meets the liquid supply pipe is sprayed into the chamber.

10. The hybrid spray pump of claim 9 , further comprising a sheath nozzle installed in the nozzle to wrap around an outer periphery of the nozzle and spray a compressed gas into an outer periphery of the particles of the viscous liquid sprayed from the nozzle.
