Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification module for air conditioners. Background Art

[0002] Traditional industrial air conditioners are not equipped with air purification modules and thus cannot achieve the functions of disinfection and purification. In scenarios such as chemical industry and food processing, it is difficult to effectively remove odor molecules and microbial pollutants. The open-air duct structure is prone to adsorb pollutants and form secondary pollution. It lacks a long-term purification mechanism, requires frequent replacement of consumables, and has high maintenance costs. In the prior art, the efficiency of a single purification method (such as only activated carbon adsorption) is limited and cannot meet the purification requirements of industrial scenarios for composite pollutants. Summary of the Utility Model

[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides an air purification module for air conditioners to decompose harmful gases, disinfect microorganisms and eliminate odors.

[0004] Technical solution of the utility model: An air purification module for air conditioners includes:

[0005] A UV photocatalyst group, which includes a first photocatalyst sheet, an activated carbon matrix and a second photocatalyst sheet arranged in sequence. UV lamps are respectively arranged between the activated carbon matrix and the first photocatalyst sheet and between the activated carbon matrix and the second photocatalyst sheet, and an ozone lamp is also arranged between the activated carbon matrix and the first photocatalyst sheet;

[0006] An anion generator, which is located behind the UV photocatalyst group.

[0007] By adopting the above technical solution, it has a multi-effect collaborative purification function. Photocatalyst + UV light oxygen realizes the decomposition of organic substances, activated carbon adsorbs odor molecules, ozone disinfects microorganisms, and anions settle dust, covering typical pollutants in industrial scenarios.

[0008] Activated carbon, by virtue of its porous structure and huge specific surface area, has a strong adsorption capacity for harmful gases in the air such as formaldehyde, benzene, TVOC, etc., can effectively remove odors and make the air fresher.

[0009] Photocatalyst sheets, under the irradiation of UV light, have strong oxidizing properties, can decompose organic pollutants in the air into harmless substances such as carbon dioxide and water, and can also kill bacteria and viruses, playing a dual role of purification and disinfection.

[0010] UV lamps provide ultraviolet rays with specific wavelengths to stimulate the photocatalyst sheets to produce photocatalytic reactions. At the same time, ultraviolet rays themselves also have a certain bactericidal effect, can destroy the DNA structure of bacteria and viruses, and inhibit their growth and reproduction.

[0011] The ozone lamp generates ozone with strong oxidizing properties, which can quickly decompose harmful gases and odor substances in the air, and can also kill microorganisms such as bacteria, viruses, and molds, with remarkable disinfection effects.

[0012] The negative ion generator has a certain cooperative effect with activated carbon, photocatalyst sheet, UV lamp, and ozone lamp in air purification: Cooperating with activated carbon: Activated carbon adsorbs harmful gases, and negative ions cause particulate matter in the air to settle. The two work together to purify the air from two aspects: adsorbing gaseous pollutants and reducing solid particulate matter. Cooperating with the photocatalyst sheet and UV lamp: The UV lamp excites the photocatalyst sheet to carry out photocatalytic reactions to decompose harmful substances. Negative ions can also decompose some harmful gases. At the same time, negative ions can improve the air ion balance, making the air fresher, and jointly enhancing the purification effect with the photocatalyst sheet and UV lamp. Cooperating with the ozone lamp: The ozone lamp generates ozone for sterilization and disinfection and decomposes harmful gases. Negative ions also have a bactericidal effect and can reduce dust. The two can work together to play a greater role in sterilization and disinfection and air purification.

[0013] Moreover, in the above-mentioned UV photocatalyst group, through the UV photocatalytic regeneration technology, the service life of the activated carbon can be extended by - times, reducing the replacement frequency and lowering the maintenance cost.

[0014] A further setting of the present utility model: A plurality of UV lamps are arranged at intervals up and down between the activated carbon matrix, the first photocatalyst sheet, and the second photocatalyst sheet. Among them, the UV lamp and the ozone lamp are in a long tubular structure.

[0015] Adopting the above further setting, the long tubular design of the UV lamp and the ozone lamp and the spaced arrangement of a plurality of UV lamps in the up and down direction result in a larger irradiation area, thereby improving the efficiency of the photocatalytic reaction and further ensuring that harmful gases on each layer of the activated carbon matrix can be effectively decomposed. This design not only enhances the air purification effect but also optimizes the utilization rate of the photocatalyst, making the performance of the entire air purification module more stable and efficient.

[0016] A further setting of the present utility model: A plurality of UV lamps between the activated carbon matrix and the second photocatalyst sheet are arranged at equal intervals; the ozone lamp and a plurality of UV lamps between the activated carbon matrix and the first photocatalyst sheet are also arranged at equal intervals.

[0017] Adopting the above further setting, the equal interval arrangement of a plurality of lamps in the up and down direction not only ensures the uniformity of sterilization and disinfection and the decomposition of harmful gases but also further improves the air purification efficiency. This arrangement allows ozone and UV light to come into contact with pollutants in the air more fully, thereby more effectively removing harmful substances.

[0018] A further setting of the present utility model: The UV photocatalyst assembly is installed in the housing and is arranged corresponding to the ventilation openings provided on the housing.

[0019] With the above further settings, in this layout design, air can smoothly and sequentially pass through the first photocatalyst sheet, the activated carbon matrix, and the second photocatalyst sheet inside the housing, achieving multi-stage purification, thus greatly improving the air purification effect. The first photocatalyst sheet and the second photocatalyst sheet can absorb ultraviolet rays and catalytically decompose organic substances and bacteria in the air, while the activated carbon matrix is responsible for adsorbing odors and harmful gases.

[0020] A further setting of the present utility model: A fixing bracket is provided inside the housing for installing a UV lamp and an ozone lamp; a clamping clip is provided on the fixing bracket, and the clamping clip is composed of a pair of clamping arms forming a clamping hole. The pair of clamping arms can elastically deform to clamp or loosen the lamp, and the ends of the pair of clamping arms are bent away from each other, thereby forming a V-shaped opening at one end of the clamping hole.

[0021] With the above further settings, the design of the fixing bracket ensures the stable installation of the UV lamp and the ozone lamp. And the pair of clamping arms of the clamping clip can clamp the lamp tube through elastic deformation to prevent loosening or falling off; at the same time, the design of the V-shaped opening makes the installation and disassembly of the lamp tube simpler and faster, improving the operation efficiency.

[0022] A further setting of the present utility model: The first photocatalyst sheet, the activated carbon matrix, and the second photocatalyst sheet are all detachably installed inside the housing.

[0023] With the above further settings, this design enables the photocatalyst sheet and the activated carbon matrix to be conveniently replaced or cleaned, thereby extending the service life of the air purification module and maintaining its purification effect. The user only needs to simply operate to take out the aged photocatalyst sheet or the saturated activated carbon matrix and install new components, without overall disassembly, greatly improving the convenience and efficiency of maintenance.

[0024] A further setting of the present utility model: The upper side of the housing is provided with an open structure, and the first photocatalyst sheet, the activated carbon matrix, and the second photocatalyst sheet are all inserted into the housing from the open opening, and respectively form an insertion and mating installation structure with the housing.

[0025] With the above further settings, the insertion and mating installation structure facilitates the quick disassembly and assembly of the photocatalyst sheet and the activated carbon matrix, and the open design facilitates the insertion and removal of each component.

[0026] Further improvement of the present utility model: The housing includes a base plate and side frames located at opposite ends of the base plate. Both ends of the activated carbon matrix respectively form an insertion and installation structure with the two side frames. Baffles are respectively arranged on both sides of the side frames. Two groups of fixing brackets are arranged inside the housing. A first insertion space is formed between one group of fixing brackets and the adjacent baffle, and the first photocatalyst sheet is inserted and installed in the first insertion space. A second insertion space is formed between the other group of fixing brackets and the adjacent baffle, and the second photocatalyst sheet is inserted and installed in the second insertion space. The lamp is installed on the side of the fixing bracket facing the activated carbon matrix.

[0027] With the above further improvement, the design of the two side frames provides stable insertion and installation support for the activated carbon matrix. The baffle and the fixing bracket on the same side cooperate to limit and fix the photocatalyst sheet, enabling the photocatalyst sheet to be stably installed inside the housing, preventing it from shaking or displacing during operation, and thus ensuring the purification effect. At the same time, the lamp is installed on the side of the fixing bracket facing the activated carbon matrix, facilitating providing light for the photocatalyst sheet and enabling it to fully exert its catalytic decomposition function.

[0028] Further improvement of the present utility model: The outer frames are wrapped around the outside of the first photocatalyst sheet, the activated carbon matrix, and the second photocatalyst sheet, and the insertion and installation structure with the housing is realized through the outer frames.

[0029] With this further improvement, the outer frames provide a unified installation reference for the first photocatalyst sheet, the activated carbon matrix, and the second photocatalyst sheet, enabling them to be more firmly installed inside the housing. At the same time, through the insertion and installation structure of the outer frames, the installation process is simplified and the installation efficiency is improved. In addition, the outer frames also play a certain protective role, preventing the photocatalyst sheets and the activated carbon matrix from being damaged during use, and thus extending their service life.

[0030] Further improvement of the present utility model: The UV photocatalyst group is arranged at the air inlet of the air conditioner, and the negative ion generator is arranged at the air inlet of the blower of the air conditioner.

[0031] With this further improvement, the UV photocatalyst group can directly purify the air entering the air conditioner. Utilizing the catalytic decomposition function of the photocatalyst, it effectively removes bacteria, viruses, and harmful gases in the air, improving the air quality. At the same time, the negative ion generator is arranged at the air inlet of the blower of the air conditioner, which can generate a large amount of negative ions, further purify the air, and increase the freshness and comfort of the air. Such a layout design enables the air purification module to play a more efficient role and provides a healthier and more comfortable indoor environment for users. Description of the Drawings
