The dust collection filter 300 may have the same shape as the above-described dust collection filter 110, but may have a smaller thickness than the above-described dust collection filter 110. For example, the thickness of the dust collecting filter 300 may be 1/2 of that of the dust collecting filter 110 described above. As will be described later, a photocatalyst may be coated on one side of the dust collection filter 300 facing the self-power generation module 400 . The photocatalyst may be, for example, TiO2 (anatase), TiO2 (rutile), ZnO, CdS, ZrO2, SnO2, V2O3, WO3, etc., but the type of photocatalyst is not particularly limited.

Due to its structural design, the self-power generation module 400 controls the direction and speed of air passing through the dust collection filter 300 to generate self-power, and uses the power generated through the self-power generation to generate the self-power module 400. The provided LED module can be operated. Accordingly, even if there is no separate power supply unit, the LED module can operate with the power generated by the self-powered module 400, and a chemical reaction between the light in the LED module and the photocatalyst can occur to cause a sterilization action.

Hereinafter, detailed structures of the dust collection filter 300 and the self-power generation module 400 will be described in more detail.

3 is a front view of the dust collection filter 300 and the self-power generation module 400 according to an embodiment of the present invention, and FIG. 4 is a perspective view of the self-power generation module 400 according to an embodiment of the present invention. 5 is an exploded view of the self-power generation module 400 according to an embodiment of the present invention.

3 to 5, the dust collecting filter 300 has a first surface through which air sucked into the dust collecting device 100 is introduced, and a second surface positioned opposite to the first surface and coated with a photocatalyst 302. contains the side The air sucked into the dust collector 100 passes through the first and second surfaces sequentially and is directed toward the self-powered module 400 .

3 to 5, the self-powered module 400 includes a first body 402, a second body 404, a support 406, a guide 408, and an LED module 410. , a self-powered structure 412, an electrode plate 414, a first wind direction guide part 416 and a second wind direction guide part 418.

The first body part 402 is coupled to the dust collection filter 300 at both sides of the self-power generation module 400 . The first body part 402 may protrude from both sides of the self-power generation module 400 and may be detachably coupled to both ends of the dust collection filter 300 . The first body portion 402 may be detachably coupled to both end portions of the dust collecting filter 300 in various ways, such as, for example, a fitting coupling, a male-female coupling, or a screw coupling.

The second body portion 404 is formed perpendicularly to the first body portion 402 and has a discharge port (T) in the center portion for discharging air passing through the self-power generation module 400 toward the fan. The second body portion 404 forms the bottom surface of the self-powered module 400, and is vertically coupled to the first body portion 402 to form an L-shaped body portion together with the first body portion 402. . As will be described later, a plurality of support parts 406 protrude from the upper surface of the second body part 404, and an electrode plate 414 is formed on the upper surface of the second body part 404 adjacent to the support part 406. Multiple coatings may be applied.

The support portion 406 is spaced apart from the second body portion 404 by a predetermined distance and protrudes vertically toward the dust collecting filter 300 . A plurality of support parts 406 may be formed on the second body part 404 and spaced apart at predetermined intervals. As will be described later, the support part 406 can support the guide part 408 . In addition, the self-power generation structure 412 may extend horizontally toward the central portion of the self-power generation module 400 on the side of the support unit 406 .

In addition, both end portions of the guide portion 408 and the first body portion 402 may be spaced apart by a predetermined distance, and accordingly, inlets S may be formed on both sides of the self-powered module 400 . Accordingly, the air passing through the dust collection filter 300 may be rapidly introduced into the inlet S along the upper surface of the guide part 408 . Since the size of the inlet (S) is smaller than that of the second surface of the dust collecting filter (300), when the air passing through the dust collecting filter (300) flows into the inlet (S), its speed is increased. The air introduced through the inlet (S) is directed toward the discharge port (T), and in the process induces vibration in the vertical direction of the self-powered structure 412 to be described later.

The LED module 410 is formed to look at the second surface from the upper surface of the guide unit 408 . As shown in FIGS. 3 to 5 , the LED module 410 may be formed in plurality by being spaced apart at predetermined intervals from the center of the upper surface, the left surface of the upper surface, and the right surface of the upper surface of the guide unit 408 . The LED module 410 may emit light by being driven from electric power generated by friction between a self-powered structure 412 and an electrode plate 414 to be described later. To this end, the LED module 410, the self-powered structure 412, and the electrode plate 414 may be interconnected through wires (not shown) or cables (not shown). The LED module 410 may, for example, emit light in a visible light region, and thus a chemical reaction between the light in the LED module 410 and the photocatalyst 302 may be promoted, thereby generating a sterilization effect.

The self-powered structure 412 extends horizontally from the side of the support 406 toward the central portion of the self-powered module 400 . The self-powered structure 412 may be, for example, a fine-sized polytetrafluoroethylene (PTFE) film or a polyurethane acrylate (PUA) film, but the type or material of the self-powered structure 412 is not particularly limited. The self-powered structure 412 may be disposed between two electrode plates 414 to be described later, and generate friction with the electrode plate 414 while being fluttered by wind to induce a flow of electrons.

The electrode plate 414 is coated on the lower surface of the guide part 408 adjacent to the support part 406 and the upper surface of the second body part 404 , respectively. The electrode plate 414 may be, for example, an aluminum electrode plate. As described above, between the two electrode plates 414, the self-powered structure 412 may extend horizontally toward the central portion of the self-powered module 400. The self-powered structure 412 vibrates in a vertical direction as air passing through the dust collecting filter 300 passes through the inlet S, causing friction with the two electrode plates 414, and thus power is generated. The generated power is transmitted to the LED module 410 through the wire or cable described above to drive the LED module 410 .

The first wind direction guide part 416 protrudes from the upper surface of the guide part 408 toward both sides of the self-power generation module 400 to guide the air passing through the dust collecting filter 300 to the inlet S. As shown in FIG. 4 , a plurality of first wind direction guide units 416 may be formed at a predetermined interval from the upper surface of the guide unit 408 . The first wind direction guide part 416 is formed on the upper surface of the guide part 408 and may be formed such that its protruding height increases toward both sides of the self-power generation module 400 . At this time, when the first wind direction guide part 416 is combined with the dust collecting filter 300, it can be in close contact with the upper surface of the second body part 404, and accordingly, the air transfer to the inlet port S is smooth and the plurality of air conditioners are provided. 1 The flow of air can be evenly distributed by the wind direction guide part 416.

The second wind direction guide part 418 protrudes from the lower surface of the guide part 408 toward the discharge port T in order to guide the air passing through the inlet S to the discharge port T. As shown in FIGS. 4 and 5 , a plurality of second wind direction guide units 418 may be formed at a predetermined distance from the lower surface of the guide unit 408 . The second wind direction guide part 418 is formed on the lower surface of the guide part 408 and may be formed such that its protruding height increases toward the discharge port T. At this time, when the second wind direction guide part 418 is combined with the dust collecting filter 300, it can be completely adhered to the second surface of the dust collecting filter 300, and accordingly, the air delivery to the discharge port T is smooth and the plurality of filters are provided. 2 The air flow can be evenly distributed by the wind direction guide part 418.

6 is an example showing the moving direction of air in the dust collection filter 300 and the self-power generation module 400 according to an embodiment of the present invention.

Referring to FIG. 6 , the air sucked into the dust collecting device 100 passes through the dust collecting filter 300 and then flows in through the inlets S on both sides of the self-powered module 400 along the upper surface of the guide part 408 . Thereafter, the air passing through the inlet (S) is discharged through the outlet (T) and directed to the fan, and in this process, vibration of the self-powered structure 412 in the vertical direction is induced. Accordingly, while the self-powered structure 412 vibrates in the vertical direction, it causes friction with the electrode plates 414 disposed on the upper and lower sides of the self-powered structure 412, and electric power is produced by this friction.

7 is an example illustrating a process of generating electric power by friction between a self-powered structure 412 and an electrode plate 414 according to an embodiment of the present invention. 7, for convenience of description, the electrode plate 414 disposed on the upper side of the self-powered structure 412 is the first electrode plate 414a, and the electrode plate 414 disposed on the lower side of the self-powered structure 412 is the second electrode plate 414a.
