| Claim: | 1. A portable sterilizer, comprising: a housing in which a water tank is installed inside; a nozzle capable of spraying sterilizing water in a fog state is installed to be exposed to an outside on a side thereof; a Y-shaped mixing tube connected to the nozzle; an ozone gas supply unit including an air pump, installed inside the housing and connected to a first branched side of the Y-shaped mixing tube and configured to supply ozone gas to the nozzle; a compressed air supply unit installed inside the housing and connected to a second branched side of the Y-shaped mixing tube and configured to supply compressed air to the nozzle, wherein the compressed air is supplied through the other end of said Y-shaped mixing tube by a compression pump providing a pressure greater than the pressure of said air pump; and a water supply unit installed inside the housing and configured to supply water from the water tank to the nozzle, wherein the ozone gas and compressed air are supplied to the nozzle in a mixed gas state, the water is supplied directly to the nozzle, and the mixed gas and water are finally mixed inside the nozzle and then sprayed with sterilizing water in a fog state, wherein the ozone gas and compressed air are mixed by the Y-shaped mixing tube and supplied to the nozzle as a mixed gas, wherein the water supply unit comprises: a water supply hose configured to connect the water tank and the nozzle and an electric valve installed on the water supply hose and configured to regulate a flow of water supplied from the water tank to the nozzle. |
| Claim: | 2. The portable sterilizer of claim 1 , wherein the ozone gas supply unit comprises: an ozone generator that generates ozone gas by mixing the air and ozone generated by the air pump; and an ozone gas supply hose connected to the first branched side of the Y-shaped mixing tube to supply the ozone gas generated by the ozone generator to the nozzle. |
| Claim: | 3. The portable sterilizer of claim 1 , wherein the compressed air supply unit comprises: a compressed air supply hose connected to a second branched side of asaid Y-shaped mixing tube to supply the compressed air generated by the compression pump to the nozzle. |
| Claim: | 4. The portable sterilizer of claim 1 , further comprising: a power supply unit for supplying power to the ozone gas supply unit, the compressed air supply unit, and the water supply unit, wherein the power supply unit is composed of a controller and a battery. |
| Claim: | 5. The portable sterilizer of claim 1 , wherein the nozzle is configured as an atomizing nozzle so as to mix the mixed gas and water. |
