Description

Technical Field

[0001] The utility model relates to the technical field of air disinfection, and in particular to an air disinfection module. 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] In air treatment devices currently using photocatalyst disinfection modules, light sources are usually used to directly irradiate the photocatalyst carrier to cause the photocatalyst to react. However, the irradiation range and intensity of the photocatalyst carrier are generally small, resulting in the photocatalyst being unable to fully react and unable to produce enough strong oxidizing substances, affecting the disinfection effect of the disinfection module. If more light sources are used for simultaneous irradiation, the cost will be greatly increased, and improvement is urgently needed. Utility Model Content

[0006] Frame;

[0007] The air intake grille is made of a light-guiding material and is arranged across the inner side of the frame. A photocatalyst is sprayed on the surface of the air intake grille.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0032] This embodiment relates to an air disinfection module, such as Figure 1-5 As shown, it includes: a frame 100, an air intake grille 200 and an LED lamp 300.

[0033] The air intake grille 200 is disposed across the inner side of the frame 100, and air can pass through the air intake grille 200. The air intake grille 200 is made of a light-guiding material, and a photocatalyst is sprayed on the surface of the air intake grille 200. An LED lamp 300 is arranged on the frame 100, and the LED lamp 300 is abutted against the surrounding side of the air intake grille 200, so that the light emitted by the LED lamp 300 can be directly introduced into the air intake grille 200. Since the air intake grille 200 is made of light-guiding material, the light of the LED lamp 300 will be inside the air intake grille 200 and transmitted to various parts of the air intake grille 200, so that the light emitted by the LED lamp 300 can fully illuminate the photocatalyst at various parts of the surface of the air intake grille 200, so as to produce strong oxidizing substances (such as hydroxyl free radicals, oxygen, etc.) on the surface of the air intake grille 200. These substances can effectively decompose the cell walls of bacteria in the air and coagulate proteins, thereby completely killing the bacteria. At the same time, formaldehyde, VOC, allergens, mites, etc. can be effectively removed to achieve the effect of disinfecting and sterilizing the air passing through the air intake grille 200.

[0034] Since the light of the LED lamp 300 is directly transmitted through the photoconductive effect of the air intake grille 200, the light can irradiate the photocatalyst on the surface of the air intake grille 200 without any blind spots, and the irradiation intensity of the light is high, so that the photocatalyst can fully perform the photocatalytic reaction to produce more effective substances and achieve a better disinfection effect. At the same time, because the photocatalyst is directly sprayed on the surface of the air intake grille 200, the air passing through the air intake grille 200 can fully contact with the effective substances produced by the photocatalyst, so as to fully disinfect the air flowing through the air intake grille 200.

[0035] In this embodiment, the air intake grille 200 includes a plurality of air intake surfaces 400 arranged in parallel, and air can pass through each air intake surface 400. A plurality of groups of LED lamps 300 are arranged, and are correspondingly arranged on the side of each air intake surface 400 so that the light emitted by the LED lamps 300 can be introduced into each air intake surface 400, achieving complete coverage of the illumination, ensuring that the photocatalyst on each air intake surface 400 can fully react, and achieving a good disinfection effect. As a preferred solution, LED lamps 300 are arranged on both the left and right sides of each air intake surface 400 to ensure the light conduction effect and conduction strength of the middle part of the air intake surface 400, and improve the air disinfection effect.

[0036] In this embodiment, the front side of the air intake grille 200 is the air intake side, and the rear side is the air outlet side. The air intake surface 400 is inclined from one end close to the air intake side to one end close to the air outlet side. The inclined setting of the air intake surface 400 can increase the overall area of ​​the air intake grille 200, which not only allows more photocatalysts to be sprayed on the surface of the air intake grille 200, but also increases the contact area between the air and the air intake grille 200. It can improve the air flow and disinfection effect. A plurality of strip-shaped airflow holes 500 are arranged in parallel on the air intake surface 400. The air passing through the strip-shaped airflow holes 500 can fully contact with the strong oxidizing substances generated on the surface of the air intake surface 400, ensuring a good disinfection effect. An air guide strip 600 is arranged at one end of the air intake surface 400 close to the air intake side. The air guide strip 600 can guide the air to the strip-shaped airflow holes 500 to achieve a good circulation effect. Preferably, the surface of the air guide strip 600 is configured as an air guide arc surface to better guide the air to the strip-shaped air flow holes 500, reduce the wind resistance coefficient of the air flowing through the air inlet surface 400, and enhance the user experience of the disinfection module.

[0037] As a preferred solution, the LED lamp 300 is arranged on the left and right sides of the air guide strip 600. The air guide strip 600 has a large cross-sectional area and can well guide light to various parts of the air inlet surface 400, ensuring good light guiding effect and light guiding intensity, and improving the air disinfection effect.

[0038] In the present invention, the air intake grille 200 is made of PMMI material such as TT50, which has high light transmittance, transparency and optical stability, and can transmit light well, so that the photocatalyst on the surface of the air intake grille 200 fully reacts to ensure a good disinfection effect. Of course, in other implementations, the air intake grille 200 is made of PC, PMMA, CBC or other PMMI materials.

[0039] As a preferred solution, the frame 100 and the air intake grille 200 are integrally formed, which can reduce the manufacturing cost of the disinfection module and improve the overall stability of the disinfection module.

[0040] In this embodiment, an ultraviolet lamp 700 is also provided on the frame 100 and shines towards the air intake grille 200. The ultraviolet lamp 700 can irradiate and disinfect the air passing through the air intake grille 200, 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 substance produced by the photocatalyst can achieve two-stage disinfection of the air flowing through the air intake grille 200, thereby improving the disinfection effect.

[0041] Preferably, the ultraviolet lamp 700 is set as a focusing UVC-LED at an angle of 30 degrees, preferably 3535UVC-LED, and multiple groups of ultraviolet lamps 700 are provided, which are correspondingly arranged on the left and right sides of each air inlet surface 400. The ultraviolet lamp 700 irradiates from the left and right sides of the air inlet surface 400 to the middle, so that the ultraviolet lamps 700 on both sides are superimposed in the middle of the air inlet surface 400, ensuring the ultraviolet irradiation intensity in the middle of the air inlet surface 400, so as to achieve a good disinfection effect. Of course, in other implementations, ultraviolet lamps of other specifications are also used to ensure a good ultraviolet irradiation disinfection effect.

[0042] In this embodiment, mounting grooves 800 are provided on both sides of the frame 100, and a circuit mounting board 900 is detachably installed in the mounting grooves 800. The LED lamp 300 is installed on the circuit mounting board 900 and abuts against the side of the air inlet surface 400. The ultraviolet lamp 700 is installed on the circuit mounting board 900. A lamp hole 110 is provided on the frame 100 for exposing the ultraviolet lamp 700 to irradiate the air inlet surface 400. While ensuring the effects of the LED lamp 300 and the ultraviolet lamp 700, the LED lamp 300 and the ultraviolet lamp 700 can be removed together with the circuit mounting board 900, so as to facilitate the maintenance and replacement of the LED lamp 300 and the ultraviolet lamp 700.

[0043] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
