Air is forcibly discharged to the outside through the blowing fan 190 located at the outlet 112.

Accordingly, the operation of the air purifying device 100 of the present invention will be described, and the operation of the blowing fan 190 causes external air to flow in through the intake port 111 and move through the first air movement space 113a.

When the air introduced through is moved to the first air movement space 113a and irradiated with light from the second UV lamp 140b mounted on the inner peripheral surface of the housing 110, the photocatalyst network 160 coated with the photocatalyst Electrons and crystals are formed through irradiation of ultraviolet rays, and OH and O2-, which have strong oxidizing power, are generated to perform comprehensive purification/deodorization/sterilization of the air.

In addition, when the air that has passed through the filter unit 180 moves into the transparent pipe 120 through the connection pipe 131, the moving speed of the air is reduced, allowing sufficient time within the transparent pipe 120 to carry out the air purification process. The following structures are included to go through:

In addition, the collision bar 320 has both ends coupled and fixed to the inside of the square bars 310 facing each other, and has an arrangement structure arranged at equal intervals, and the direction of movement is dispersed when air collides with the collision bar 320. As this happens, it collides with the air trying to pass between the collision bars 320, thereby controlling the flow of air.

And, as shown in Figures 8 and 9, the collision bar 320 of the wind speed inducing member 300 is formed in a square cross-section and has a circular air pipe 321 penetrating along the length of the collision bar 320. It is formed by a plurality of intervals,

It is inserted and fixed into the air pipe 321, and the upper and lower surfaces are horizontal surfaces, the outer diameter gradually increases toward the upper part, and the discharge inductor 400 is formed with a discharge passage 401 cut from the center of the lower surface to a predetermined length from the upper part.
