Technical Field

[0001] The invention relates to the technical field of air purification, and in particular to a photoconductive catalytic filtering structure. Background Art

[0002] Photocatalyst, also known as photocatalyst, is a general term for semiconductor materials with photocatalytic functions, represented by nano-scale titanium dioxide. It can produce strong oxidizing substances under light irradiation, can effectively degrade toxic and harmful gases in the air such as formaldehyde, and efficiently purify the air. At the same time, it can effectively kill a variety of bacteria. Therefore, the application of photocatalyst in air purification devices is very common.

[0003] At present, in air treatment devices using photocatalyst disinfection modules, a light source is usually used to directly irradiate the photocatalyst carrier to make the photocatalyst react. However, the irradiation range of the general light source irradiating the photocatalyst carrier is small and the irradiation intensity is low, which causes the photocatalyst to be unable to fully react and unable to produce enough strong oxidizing substances, affecting the disinfection effect of the disinfection module. Summary of the invention

[0006] Frame;

[0007] A light guide strip, made of a light guide material, is arranged across the inner side of the frame;

[0008] A honeycomb filter is disposed in the frame and located on the upper side of the light guide strip, and a photocatalyst is disposed on the honeycomb filter;

[0009] An LED lamp is arranged on the frame and abuts against the end of the light guide bar to guide the light emitted by the LED lamp into the interior of the light guide bar, and then irradiates the honeycomb filter through the light guide bar, so that the photocatalyst on the honeycomb filter reacts fully to disinfect the air passing through the honeycomb filter.

[0010] The present invention further provides that the light guide strips are provided in multiple groups, and the multiple groups of light guide strips are mutually parallel and spaced apart.

[0011] The present invention further provides that the light guide strip spans the left and right sides of the frame and is parallel to the front edge of the frame;

[0012] The LED lamps are provided in two groups, respectively abutting against the left and right ends of the light guide bar.

[0015] The present invention further provides that the honeycomb filter is coated with titanium dioxide.

[0016] The present invention further provides that a honeycomb fixing plate is provided on the upper side of the honeycomb filter, and fixing holes for connecting the honeycomb fixing plate are provided above the frame; and a supporting plate for supporting the honeycomb filter is provided inside the frame.

[0017] The present invention further provides that an ultraviolet lamp is provided on the frame and below the honeycomb filter to illuminate the honeycomb filter.

[0018] The present invention is further arranged that the ultraviolet lamp is arranged as a 30-degree focusing UVC-LED, and the ultraviolet lamp is provided in multiple groups, which are correspondingly arranged on the left and right sides of each of the frames.

[0021] In the present invention, the light of the LED lamp will be transmitted to various places of the light guide bar in the light guide bar, so that the light can be irradiated to the honeycomb filter through various places of the light guide bar, increasing the irradiation range of the light, so that the photocatalyst on the honeycomb filter can be fully catalyzed to react, so as to produce strong oxidizing substances (such as hydroxyl radicals, oxygen, etc.) on the surface of the honeycomb filter. These substances can effectively decompose the cell walls of bacteria in the air and coagulate proteins, thereby completely killing bacteria. They can also effectively remove formaldehyde, VOC, allergens, mites, etc., so as to achieve the effect of disinfection and sterilization of the air passing through the honeycomb filter.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0034] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0035] This embodiment relates to a photoconductive catalytic filtering structure, such as Figure 1-9 As shown, it includes: a frame 100 , a light guide bar 200 , a honeycomb filter 300 and an LED lamp 400 .

[0036] Among them, the light guide strip 200 is made of light guiding material and is arranged across the inner side of the frame 100; the honeycomb filter 300 is embedded in the inner side of the frame 100 and is located above the light guide strip 200, and a photocatalyst is arranged on the surface of the filter, and the photocatalyst is loaded onto the honeycomb filter 300 by spraying or other means. The LED lamp 400 is arranged on the frame 100 and abuts against the end of the light guide bar 200, so that the light emitted by the LED lamp 400 can be directly introduced into the light guide bar 200. Since the light guide bar 200 is made of light-guiding material, the light of the LED lamp 400 will be transmitted to various parts of the light guide bar 200 in the light guide bar 200, so that the light can be irradiated onto the honeycomb filter 300 through various parts of the light guide bar 200, thereby increasing the irradiation range of the light, so that the photocatalyst on the honeycomb filter 300 can be fully catalyzed to produce strong oxidizing substances (such as hydroxyl free radicals, oxygen, etc.) on the surface of the honeycomb filter 300. These substances can effectively decompose the cell walls of bacteria in the air and coagulate proteins, thereby completely killing bacteria, and can also effectively remove formaldehyde, VOC, allergens, mites, etc., so as to achieve the effect of disinfection and sterilization of the air passing through the honeycomb filter 300. At the same time, the high-efficiency dust and particle filtering effect of the honeycomb filter 300 is maintained, thereby achieving the dual effects of filtering and disinfection. A honeycomb filter 300 is used, and a plurality of hexagonal honeycomb holes 310 are arranged on its surface, so that the surface area of ​​the honeycomb filter 300 is larger, which not only increases the filtering area of ​​the filter, but also has the advantages of smaller air resistance and large filtering flow. At the same time, more photocatalysts can be loaded on the honeycomb filter 300 to achieve better air purification effect.

[0037] In this embodiment, the upper side of the frame 100 is the air inlet surface, and the lower side is the air outlet surface, so that the honeycomb filter 300 can filter the air well. The light guide bar 200 transmits light to the photocatalyst on the honeycomb filter 300, and sterilizes the passing air. At the same time, it can also play a certain supporting and protective role for the honeycomb filter 300, so as to prevent the honeycomb filter 300 from being deformed and damaged or falling out of the inner side of the frame 100 when the air intake is too large, thereby ensuring the stability of the filtering structure. Of course, in other embodiments, the light guide bar 200 can also be set on the upper side of the honeycomb filter 300, and can also irradiate the honeycomb filter 300 to make the photocatalyst fully react.

[0038] As a preferred solution, the light guide bar 200 is arranged on the inner side of the frame 100, across the left and right sides of the frame 100, and parallel to the front edge of the frame 100. Two groups of LED lamps 400 are arranged, respectively abutting the left and right ends of the light guide bar 200 to ensure the light conduction and irradiation effect of the light guide bar 200, and improve the air disinfection effect. In this embodiment, multiple groups of light guide bars 200 are arranged, and the multiple groups of light guide bars 200 are parallel to each other and arranged at intervals to allow air to pass smoothly. Each group of light guide bars 200 is correspondingly provided with an LED lamp 400. At the same time, the honeycomb filter 300 is irradiated by multiple groups of light guide bars 200, so that the photocatalyst on the honeycomb filter 300 fully reacts to achieve a good disinfection effect.

[0039] In this embodiment, the upper side of the light guide bar 200 is set as an air guide arc surface 210 to guide the air on the upper side of the light guide bar 200 to the two sides of the light guide bar 200, so that the air passes through the light guide bar 200 smoothly, thereby reducing the air resistance of the light guide bar 200 and ensuring the filtering flow of the filtering structure. The air guide arc surface 210 is set to a bullet-shaped or other shaped air guide arc to reduce the wind resistance of the light guide bar 200. The LED lamp 400 abuts against the middle and lower part of the light guide bar 200 so that the light of the LED lamp 400 is well introduced into the interior of the light guide bar 200. As a preferred solution, a serrated reflective surface 220 is provided at the bottom of the light guide bar 200 and extending along the length direction of the light guide bar 200. The serrated light guide surface can reflect the light inside the light guide bar 200 upward to reflect the light onto the honeycomb filter 300, so that the light enters the hexagonal honeycomb holes 310 of the honeycomb filter 300, so as to achieve a good catalytic effect on the photocatalyst on the honeycomb filter 300 and disinfect the air.

[0040] As a preferred solution, a second reflective surface 230 is provided on both sides of the bottom of the light guide bar 200 to reflect the light inside the light guide bar 200 to both sides above the light guide bar 200 to increase the light irradiation range of the light guide bar 200, so that the light is reflected into the hexagonal honeycomb holes 310 on both sides of the light guide bar 200 of the upper honeycomb filter 300, and shines into the hexagonal honeycomb holes 310 on both sides of the light guide bar 200 of the upper honeycomb filter 300, catalyzing the photocatalyst in the hexagonal honeycomb holes 310, thereby increasing the light irradiation reaction area of ​​the photocatalyst on the honeycomb filter 300 and improving the filtering and disinfection effect of the honeycomb filter 300. In this embodiment, the honeycomb filter 300 is coated with titanium dioxide, which can effectively kill bacteria and viruses in the air and improve the air disinfection effect. At the same time, when light is irradiated into the hexagonal honeycomb holes, it will be diffusely reflected on the surface of the titanium dioxide particles, so that the light can irradiate various places inside the hexagonal honeycomb holes, ensuring that the photocatalyst in the hexagonal honeycomb holes can be fully irradiated and reacted, thereby achieving a good filtering effect.

[0041] In this embodiment, a honeycomb fixing plate 500 is arranged on the upper side of the honeycomb filter 300, and a hole for connecting the honeycomb fixing plate 500 is arranged above the frame 100 to fix the honeycomb filter 300 to the frame 100; a supporting plate 130 for supporting the honeycomb filter 300 is arranged on the inner side of the frame 100 to support the lower side of the honeycomb filter 300 to prevent the honeycomb filter 300 from being deformed and damaged or falling out of the inner side of the frame 100 when the incoming wind is too strong, thereby achieving stable connection of the honeycomb filter 300 and ensuring the stability of the filtering structure.

[0042] As a preferred solution, an ultraviolet lamp 700 is also provided on the frame 100 and below the honeycomb filter 300 to illuminate the honeycomb filter 300. The ultraviolet lamp 700 can irradiate and disinfect the air passing through the lower volume of the honeycomb filter 300, and can destroy the molecular structure of DNA or RNA in the cells of the pathogenic organism to kill the bacterial cells, thereby achieving the effect of disinfection and sterilization. The strong oxidizing substances produced by the photocatalyst can achieve two-stage disinfection of the air flowing through the honeycomb filter 300, thereby improving the disinfection effect. Preferably, the ultraviolet lamp 700 is set as a 30-degree focusing UVC-LED, and multiple groups of ultraviolet lamps 700 are provided, correspondingly arranged on the left and right sides of each air inlet surface. The ultraviolet lamp 700 irradiates from the left and right sides of the honeycomb filter 300 to the middle, so that the ultraviolet lamps 700 on both sides are superimposed in the middle of the honeycomb filter 300, ensuring the ultraviolet irradiation intensity in the middle of the honeycomb filter 300, so as to achieve a good disinfection effect.

[0043] In this embodiment, mounting grooves 110 are provided on both sides of the frame 100, and a circuit mounting board 600 is detachably installed in the mounting grooves 110. The LED lamp 400 is installed on the circuit mounting board 600 and abuts against the side of the light guide bar 200. The ultraviolet lamp 700 is installed on the circuit mounting board 600. A lamp hole 120 is provided on the frame 100 for exposing the ultraviolet lamp 700 to irradiate the air intake plate. While ensuring the effects of the LED lamp 400 and the ultraviolet lamp 700, the LED lamp 400 and the ultraviolet lamp 700 can be removed together with the circuit mounting board 600, so as to facilitate the maintenance and replacement of the LED lamp 400 and the ultraviolet lamp 700.

[0044] As a preferred solution, a silicone package frame 800 is provided on the outside of the frame 100. The silicone package frame 800 is wrapped around the outside of the frame 100 to provide cache protection and waterproofing for the frame 100 and improve the overall stability of the filtering structure. At the same time, the silicone package frame 800 can also increase the air tightness between the filtering structure and the filtering channel, ensuring that air passes through the honeycomb filter 300 in the middle to achieve a good filtering effect.

[0045] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
