Hereinafter, the operation process of the medium activating device described above will be described.

After moving the medium activation device 10 to the sterilization target point, the user holds the handle 211 of the case 210 and pulls the spray gun module 200 out of the body module 100 so that it faces the sterilization target point. .

When the medium activation device 10 is operated, the gas compressor 160 and the pump 150 are operated. The gas compressor 160 compresses ambient air and supplies the compressed gas to the activation gas generator 230 through the gas supply line 231. In addition, the pump 150 supplies the liquid medium stored in the medium storage tank 140 to the first flow path 221 of the nozzle 220 through the medium supply line 250.

The activation gas is supplied to the second flow path 225 of the nozzle 220 through the activation gas supply line 240.

The liquid medium is sprayed at high pressure in the form of droplets or mist through the flow path change region 223 and the first spray port 222 in the first flow path 221.

The activation gas is injected to the outside in the second passage 225 through the passage inclined region 227 and the second spray port 226. The area of the second channel 225 through which the activation gas is introduced has a larger channel width than the channel inclined area 227. Therefore, the area of the second flow path 225 is provided as a buffer space in which the activation gas can be sufficiently filled.

When the region of the second flow path 225 is sufficiently filled with the activation gas, the activation gas moves along the flow path inclined region 227 and is injected into the second spray port 226. The injected activation gas is introduced into the medium by the flow of the medium sprayed from the first spray port 222.

Since the flow path inclined region 227 has a constant flow width, the activating gas can be introduced at a uniform flow rate and flow rate in the entire area of the second spray port 226.

Referring to FIG. 7, the activation gas g is sprayed toward a medium m sprayed in a droplet or mist state. The activation gas g is injected obliquely toward the central axis of the first atomizing port 222 from the ring-shaped second atomizing port 226, and thus is injected so as to surround the entire spray area of the medium m. Accordingly, the medium m in the droplet or mist state may be uniformly combined with the activation gas g and diffuse into the atmosphere.

The activity of the medium m in a droplet or mist state is improved by combining with the activation gas g. By improving the activity of the medium (m), the sterilizing power is increased. In particular, the medium m in a droplet or mist state is mainly combined with ozone radicals contained in the activation gas g, so that the sterilizing power may be further improved.

The activated medium (m) diffuses into the atmosphere and sterilizes pollutants. The user checks the laser light irradiated by the laser generator 260 and can supply the activated medium to the contaminated area.

9 is a view showing a spray gun module according to another embodiment of the present invention. Referring to FIG. 9, the spray gun module 200 further includes a magnetic induction coil 270. The magnetic induction coil 270 is wound a plurality of times along the circumference of the nozzle 220. A current is applied to the magnetic induction nose 270, and a magnetic field is generated inside the nozzle 220 by the applied current. The magnetic field helps the activating gas to stably maintain a radical state.

In general, radicals have a short half-life in atmospheric pressure, not in vacuum, so they can lose energy within a short time and return to a stable state. To prevent this, the present invention continuously supplies energy to the activation gas by generating a magnetic field inside the nozzle 220. Therefore, the activation gas may be injected from the second spray port 226 in a radical state.

In the above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to specific embodiments, and should be interpreted by the appended claims. In addition, those who have acquired ordinary knowledge in this technical field should understand that many modifications and variations can be made without departing from the scope of the present invention.
