It has a structure in which it is moved to the diffusion tube 132 through (121) and discharged to the outside through the blowing fan 190 described above.

And, as shown in Figures 3 and 4, the first UV lamp 140a is configured to have a length corresponding to the transparent tube 120 and can provide a light source with a fixed bandwidth, and is located at the upper and lower ends in the longitudinal direction.

When the light generated from the first UV lamp (140a) undergoes a photochemical reaction with the titanium dioxide photocatalyst material coated on the photocatalyst screw (150), the titanium dioxide photocatalyst material produces polarized electrons (e-) and holes (h+). At this time, the generated electrons and holes collide with oxygen (O2) and water molecules (H2O) contained in the fluid introduced into the housing 110 through the intake port 111, forming OH- (hydroxyl group) and O2- generates ions.

It can be used semi-permanently as there is no deterioration in performance even when used for a long time. It is not limited to this, and functional filters such as carbon filters, photocatalytic filters, titanium filters, and HEPA filters can also be used.

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. The air moving in the first air movement space (113a) undergoes a primary photocatalytic reaction by the photocatalyst mesh 160 and the first UV lamp (140a), and the air in the first air movement space (113a) is transmitted through the transparent tube ( 120) It flows into and moves inside the transparent tube 120 through the air moving pipe part 130 located on the lower side, and at this time, secondary energy is generated by the photocatalyst screw 150 and the first UV lamp 140a accommodated inside the transparent tube 120. A photocatalytic reaction occurs, and the air in the transparent tube 120 passes through the air moving pipe part 130 located on the upper side of the transparent tube 120, passes through the blowing fan 190, and then the purified air is released to the outside through the outlet 112. is released.

And, as shown in FIG. 3, a plurality of second UV lamps 140b are installed in the circumferential direction at equal intervals on the inner peripheral surface of the housing 110 located in the first air movement space 113a, and the inlet 111 is provided. 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.

And, as shown in FIG. 7, it is installed on the inner bottom surface of the lower body 110b, and the outer peripheral end is connected to the inner peripheral surface of the lower body 110b, and a hemispherical first hole 211 is formed through the center. A collection guiding member (200) consisting of a collection unit (210) and a convex impact part (220) whose upper end is connected to the first port (211) of the collection unit (210) and whose sealed bottom surface protrudes upward. A purification device 100 including a is provided.

The collection inducing member 200 serves to induce the air moved into the first air movement space 113a to move into the diffusion pipe 132 of the air movement pipe part 130 located on the lower side of the transparent pipe 120. That is, in the absence of the collection inducing member 200, the air moving into the first air movement space 113a changes direction while colliding with the inner bottom surface of the lower body 110b of the housing 110 and forms the transparent pipe 120. It flows into the diffusion pipe 132 of the air moving pipe 130 located on the lower side. At this time, the air collides with the inner bottom surface of the lower body 110b, and instead of the entire air flowing into the diffusion pipe 132, some of the air is It is dispersed into the first air movement space 113a and acts as an element that impedes the movement of air.

If the collecting unit 210 is convex at the bottom, the collision unit 220 is located at the upper end. It is convex and has a shape that faces each other.

Accordingly, the air moving through the first air movement space 113a collides with the concave surface of the collection unit 210 and flows into the first opening 211 in the center of the collection unit 210, thereby causing the first opening 211. As it flows into the interior of the collision unit 220 connected to the air, it collides with the convex surface inside the collision unit 220, rapidly changing the direction of air movement, and at the same time, the moving speed accelerates, causing the air to collide with the concave surface of the collection unit 210. is recruited and guided to move to the diffusion tube 132 of the air moving tube 130.

In addition, when the air that has passed through the filter unit 180 moves into the transparent pipe 210 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 (b), the collision bar 320 of the wind speed inducing member 300 is formed in a circular cross-section, and has an upper surface opposite to the lower surface adjacent to the filter unit 180. If this plane is along the length of the collision bar 320, the purifier 100 is provided with an air movement path 321 of a predetermined length cut through from the center to the center of the upper surface.

The air movement path 321 formed in the collision bar 320 corresponds to the direction of movement of the air passing through the diffusion tube 132 or the filter unit 180, and the air pressure of the air movement path 321 causes the collision bar to move. The air that has passed through 320 or the air that has passed between the collision bars 320 is collided and spreads in an irregular direction to control the movement of air.

In addition, as shown in (c) of FIG. 9, a purification device 100 is provided in which the width of the air movement path 321 gradually increases toward the top of the collision bar 320.

When air passes through the air movement path 321 formed in the collision bar 320, the accelerated air passes through the air movement path 321 in the narrow space and then the wind pressure increases through the air movement path 321 in the large space. As the air spreads and moves as it decreases, it collides with the air that passed through the collision bar 320 or the air that passed between the collision bars 320, thereby controlling the flow of air.

Additionally, the vertical cross-section of the collision bar 320 may be formed in a shape other than a circle, as follows.

As shown in FIG. 10, the collision bar 320 of the wind speed guiding member 300 has a hemispherical vertical cross-section, and is formed with a concave surface portion 322a at the top and a convex surface portion 322b at the bottom,

A purifier 100 is provided in which a plurality of ring-shaped collision pins 323, both ends of which are connected to the lower convex surface portion 322b of the collision bar 320, are formed at equal intervals along the length of the collision bar 320. .

The collision bar 320 causes the air passing through the diffusion tube 132 or the filter unit 180 to collide with the collision bar 320, dispersing the direction of movement of the air and dividing the air passing between the collision bars 320. By reducing the flow of air that collides and passes between the collision bars 320, it serves to maximize the purification process within the transparent pipe 120 for a sufficient amount of time and air volume.

In addition, the convex surface portion 322b of the collision bar 320 is located in a direction facing the diffusion tube 132 or the filter unit 180, and air collides with the convex surface portion 322b of the collision bar 320. By dispersing the direction of movement, the flow of air is slowed down by the “U” shaped collision pin 323. At this time, it collides with the air passing between the collision bars 320, further reducing the air movement speed and forming a transparent pipe. (120) It is moved inside.

In addition, although not shown in the drawing, a spring-shaped collapsing spring (not shown) is further included, which is bound to the inside of the collision pin 323 and surrounds the collision bar 320, and the collision spring consists of two or three It is formed in the form of a coil spring that is wound and spaced apart from each other, and is installed to surround the outer circumference of the collision bar 320 while being bound to the inside of the “U”-shaped collision pin 323. In this case, the collision pin 323 Inside, the upper and lower surfaces of the collision spring are arranged in close contact.

As air rubs against the collision pin 323, it is located inside the collision pin 323 and rubs against a collision spring wrapped around the bump bar 320 to disperse the flow of air. At this time, the crash bar 323 The air moves to the transparent pipe 120 with the flow controlled by dispersing the direction of the air passing through.

In the above, the present invention has been shown and described with reference to specific specific embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the technical spirit of the present invention.
