Description

Technical Field

[0001] The invention relates to the technical field of air filtration, and in particular to a photocatalyst filtration structure. Background Art

[0002] Traditional filtering structures usually intercept dust and particulate matter through filters, and do not have the function of actively decomposing odors. Instead, they absorb odors by adding activated carbon, which easily becomes saturated and will emit odors.

[0003] 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 photocatalysts in air purification devices is very common.

[0004] At present, some filters are equipped with photocatalysts, and light sources are used to directly irradiate the photocatalyst carrier to produce active oxygen substances and decompose organic or inorganic gas molecules on the filter; however, the irradiation range and intensity of the general light source irradiating the photocatalyst carrier are small, which makes the photocatalyst unable to fully react and unable to produce enough strong oxidizing substances, affecting the disinfection effect of the disinfection module; and using more light sources for simultaneous irradiation will greatly increase the cost, which is urgently needed to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide a photocatalyst filtering structure in view of the defects and shortcomings of the prior art, which has the advantages of sufficient photocatalyst reaction, good disinfection effect, low cost and small occupied volume.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a photocatalyst filtering structure, comprising:

[0007] Frame;

[0008] A light guide strip, made of a light guide material, is arranged across the inner side of the frame;

[0009] A filter is disposed in the frame and located on the upper side of the light guide strip, and a photocatalyst is disposed on the filter;

[0010] The 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 filter through the light guide bar, so that the photocatalyst on the filter fully reacts to disinfect the air passing through the filter.

[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.

[0013] 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.

[0014] The present invention further provides that a reinforcing rib is also provided on the inner side of the frame body, and the reinforcing rib is perpendicular to the light guide bar and connected to the light guide bar.

[0015] The present invention further provides that a surface of the filter close to the light guide bar is provided with a groove corresponding to the light guide bar; the light guide bar is at least partially provided inside the groove, and a gap is provided between the light guide bar and the inner wall of the groove.

[0016] The present invention further provides that a photocatalyst is provided on the surface of the light guide strip.

[0017] The present invention further provides that the upper side of the light guide strip is provided as a wind guide arc surface.

[0018] The present invention further provides that a sawtooth reflective surface is provided at the bottom of the light guide strip to reflect the light inside the light guide strip toward the filter side.

[0019] The present invention further provides that the left and right sides of the frame are provided with mounting grooves, a circuit mounting board is detachably mounted in the mounting groove, the LED lamp is mounted on the circuit mounting board and abuts against the side surface of the light guide bar.

[0020] The present invention further provides that the frame and the light guide strip are integrally formed.

[0021] After adopting the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In the present invention, the LED lamp is arranged on the frame and abuts against the end of the light guide bar, so that the light emitted by the LED lamp can be directly introduced into the light guide bar. Since the light guide bar is made of light-guiding material, the light of the LED lamp will be transmitted to various parts of the light guide bar in the light guide bar, so that the light can be irradiated onto the filter through various parts of the light guide bar, increasing the irradiation range of the light, so that the photocatalyst on the filter can be fully catalyzed to produce strong oxidizing substances on the surface of the filter, achieving the effect of disinfection and sterilization of the air passing through the filter. At the same time, the filter also maintains the high-efficiency dust and particle filtration effect, thereby achieving the dual effects of filtration and disinfection.

[0023] 2. In the present invention, a groove 3 is provided on one side of the filter close to the light guide bar, corresponding to the light guide bar. The light guide bar can cooperate with the groove on the filter, so that the upper part of the light guide bar or even the entire light guide bar is placed inside the groove. Not only can the filter be better embedded in the inner side of the frame, reducing the overall volume of the filter structure; but also the light guide bar can well illuminate the inner walls on the left and right sides of the groove, reducing the illumination distance between the light guide bar and the filter, so that the photocatalyst on the filter can be fully catalyzed and reacted, ensuring a good disinfection and filtration effect. There is a certain gap between the light guide bar and the inner wall of the groove 310, so that air can pass smoothly between the light guide bar and the inner wall of the groove to avoid affecting the air flow of the filter. The grooves on the lower side of the filter are evenly arranged corresponding to the light guide bar, so as to increase the area illuminated by the light guide bar, so that the photocatalyst on the filter can fully react and achieve a good disinfection and disinfecting effect.

[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 photocatalyst filtering structure, such as Figure 1-7 As shown, it includes: a frame 100, a light guide bar 200, a 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 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 300, and the photocatalyst is loaded onto the 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 a 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 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 filter 300 can be fully catalyzed to produce strong oxidizing substances (such as hydroxyl free radicals, oxygen, etc.) on the surface of the 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 filter 300. At the same time, the filter 300 also maintains the efficient dust and particle filtering effect, thereby achieving the dual effects of filtering and disinfection.

[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 filter 300 can filter the air well. The light guide bar 200 transmits light to the photocatalyst on the filter 300, disinfects the passing air, and can also play a certain supporting and protective role on the filter 300, so as to prevent the 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 filter 300, and the filter 300 can also be irradiated 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 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, and the filter 300 is irradiated by multiple groups of light guide bars 200 at the same time, so that the photocatalyst on the filter 300 fully reacts to achieve a good disinfection effect.

[0039] In this embodiment, reinforcing ribs 500 are also arranged across the inner side of the frame 100. The reinforcing ribs 500 are arranged vertically with the light guide bar 200 and are interconnected with the light guide bar 200 to support the light guide bar 200 and ensure the structural stability of the light guide bar 200. As a preferred solution, a photocatalyst is also arranged on the surface of the light guide bar 200. The light of the LED lamp 400 is introduced into the light guide bar 200, which can directly irradiate and catalyze the photocatalyst on the light guide bar 200. In combination with the photocatalyst on the filter 300, secondary disinfection of the air can be achieved, thereby improving the disinfection and filtration effect.

[0040] As a preferred solution, a side of the filter 300 close to the light guide bar 200 is provided with a groove 310 corresponding to the light guide bar 200, and the light guide bar 200 can cooperate with the groove on the filter 300, so that the upper part of the light guide bar 200 or even the entire light guide bar 200 is placed inside the groove 310. Not only can the filter 300 be better embedded and set inside the frame 100, reducing the overall volume of the filtering structure; but also the light guide bar 200 can well illuminate the inner walls on the left and right sides of the groove 310, reducing the irradiation distance between the light guide bar 200 and the filter, so that the photocatalyst on the filter 300 can be fully catalyzed to ensure a good disinfection and filtration effect. There is a certain gap between the light guide bar 200 and the inner wall of the groove 310, so that air can pass smoothly between the light guide bar 200 and the inner wall of the groove 310, avoiding affecting the air flow of the filter 300. A plurality of grooves 310 are evenly arranged on the lower side of the filter 300 corresponding to the light guide strips 200 to increase the area illuminated by the light guide strips 200, allowing the photocatalyst on the filter 300 to fully react and achieve a good disinfection effect.

[0041] 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 as 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, the bottom of the light guide bar 200 is provided with a sawtooth reflective surface 220 extending along the length direction of the light guide bar 200. The sawtooth light guide surface can emit the light inside the light guide bar 200 upward to irradiate the light onto the filter 300, thereby achieving a good photocatalytic effect to disinfect the air.

[0042] In this embodiment, mounting grooves 110 are provided on both sides of the frame 100, and a circuit mounting board 600 is detachably mounted in the mounting grooves 110, and the LED lamp 400 is mounted on the circuit mounting board 600. A lamp hole 120 is provided on the frame 100 and on the side of the light guide bar 200 for the LED lamp 400 to abut against the end of the light guide bar 200, so as to ensure the installation stability and good effect of the LED lamp 400; the LED lamp 400 can be removed together with the circuit mounting board 600, so as to facilitate the maintenance and replacement of the LED lamp 400. At the same time, the LED lamp 400 is arranged inside the mounting groove 110, so that the LED lamp will not directly contact the filtered air, so as to avoid the moisture or other substances in the filtered air from causing damage and corrosion to the LED lamp 400, and ensure the stability of the use of the LED lamp 400.

[0043] In the present invention, the light guide bar 200 is made of a PMMI material such as TT50. TT50 has high light transmittance, transparency and optical stability, and can transmit light well, so that the light guide bar 200 can well illuminate the filter 300, and the photocatalyst can fully react to ensure a good disinfection effect. Of course, in other implementations, the light guide column is made of PC, PMMA, CBC or other PMMI materials. As a preferred solution, the frame 100 and the light guide bar 200 are integrally formed, which can reduce the manufacturing cost of the filter structure and improve the overall stability of the filter structure.

[0044] 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.
