[0034] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a detachable, modular air filter.

[0035] like Figures 1-9 As shown, this utility model embodiment provides a detachable splicing air filter, including a filter housing 100 for installing equipment, and a dust filter section 400 disposed inside the filter housing 100 for filtering air. The dust filter section 400 is disposed on the upper end of the fan section 150 inside the filter housing 100.

[0036] The dust filtration unit 400 includes a filter box 410 for filtering the internal airflow. The filter box 410 has locking parts 420 on both the upper and lower sides for sealing the ends. The filter box 410 has traction feet 430 on both sides for fixing the internal parts. The traction feet 430 on both sides have connecting screws 440 installed inside for traction and fastening the internal parts. The connecting screws 440 are fixed by nuts with threads fastened at the upper end.

[0037] After the air filter has been working for a period of time, the upper air inlet hood 110, rotating frame 200, and filter cover 120 can be disassembled, and the internal dust filter 400 can be removed. The filter box 410 is locked by the connecting screw 440 installed on the side. After disassembly, the upper fixing bracket 412 can be removed. Then, all the filter components installed inside can be disassembled and removed for replacement or cleaning. The splicing installation simplifies the cleaning and replacement process of the internal filter box 410. The filter box 410 is locked by the connecting screw 440 installed on the side, ensuring the stability of the structure and facilitating quick disassembly and assembly. Whether it is a professional technician or an ordinary user, they can easily maintain the filter, greatly reducing the difficulty of operation and time cost. It also allows users to flexibly select the appropriate filter components according to actual needs to achieve the best air purification effect, which not only improves maintenance efficiency but also extends the service life of the equipment.

[0038] The filter box 410 includes a first fixing frame 411 and a second fixing frame 412 installed on both sides for clamping the internal components. Inside the first fixing frame 411 and the second fixing frame 412, a primary filter frame 413 for filtering dust and impurities in the air, an activated carbon filter frame 414 for filtering pollen and other substances, and a HEPA filter layer 415 for filtering mold and other fine particulate matter are sequentially installed. The primary filter frame 413, the activated carbon filter frame 414, and the HEPA filter layer 415 are all interlocked and equipped with the first fixing frame 411. The first and second mounting brackets 412 securely hold the internal components. The primary filter 413 effectively removes larger dust impurities from the air, reducing the burden on subsequent filter layers. The activated carbon filter 414 further adsorbs and removes allergens such as pollen from the air, improving air quality and providing users with a healthy breathing environment. The HEPA filter layer 415 is specifically designed for high-efficiency filtration of fine particulate matter, such as mold spores, with a filtration efficiency of up to 99.97% for particles larger than 0.3 micrometers, greatly reducing the content of harmful substances in the air.

[0039] The lower end of the HEPA filter layer 415 is equipped with a UV lamp sterilization section 416 and a photocatalytic sterilization section 417 for further treating the air passing through. The UV lamp sterilization section 416 and the photocatalytic sterilization section 417 are matched with the frames on both sides. The UV lamp sterilization section 416 can emit ultraviolet light of a specific wavelength to achieve efficient sterilization and disinfection. The photocatalytic sterilization section 417 utilizes the strong oxidizing free radicals generated under light conditions to effectively degrade harmful gases in the air such as formaldehyde, benzene and other volatile organic compounds, and inhibit the activity of bacteria and viruses, thereby further improving air quality and providing users with a healthier breathing environment.

[0040] The upper and lower sides of the snap-fit ​​component 420 are provided with elastic sleeves 180 for auxiliary sealing. The elastic sleeves 180 on both sides are connected to the upper end of the fan part 150 located at the upper and lower ends of the inner wall of the filter housing 100, respectively. The elastic sleeves 180 installed by screws provide auxiliary sealing for the upper and lower ends to prevent leakage in the air filtration and delivery route, which would affect the filtration effect.

[0041] The upper part of the filter housing 100 is magnetically fitted with an air inlet shroud 110 for protecting the internal parts.

[0044] After a period of use, the exhaust fan 170 can be turned on intermittently through the control unit to draw air from the upper air inlet 310 through the conveying pipe 330, thereby sucking up the impurities cleaned from the upper rotating frame 200 and concentrating the impurities at the upper end of the rotating frame 200 for easy collection and to prevent the accumulation of dust and impurities.

[0045] The air inlet 310 is located at the lower end of the rotating frame 200 and is a long arc-shaped slot, which facilitates the collection of impurities.

[0046] The lower end of the filter housing 100 is provided with a pull-out groove 340 for installing the collection bag 350. The collection bag 350 is slidably installed inside the pull-out groove 340 and is adapted to the size of the pull-out groove 340. The upper end of the collection bag 350 is fixedly installed with a support frame 360 ​​for supporting it. The support frame 360 ​​is slidably installed inside a mounting slide 370 on one side for fixing. The slider provided at the upper end of the support frame 360 ​​is matched and installed with the mounting slide 370. One end of the mounting slide 370 is fixedly connected to a pull-out plate 380 provided on one side. After a period of time, the pull-out plate 380 can be pulled out, and the collection bag 350, which is movably installed on one side, can be removed for easy replacement and cleaning. The slider is matched and installed with the mounting slide 370 for easy installation and disassembly.

[0047] The working principle of a detachable, modular air filter: After the air filter has been working for a period of time, the upper air inlet cover 110, rotating frame 200, and filter cover 120 can be disassembled, and the internal dust filter 400 can be removed. The filter box 410 is locked by the connecting screw 440 installed on the side. After disassembly, the upper fixing bracket 412 can be removed. Then, all the filter components installed inside can be disassembled and removed for replacement or cleaning. The modular installation simplifies the cleaning and replacement process of the internal filter box 410. The filter box 410 is locked by the connecting screw 440 installed on the side, ensuring the stability of the structure and facilitating quick disassembly and assembly. Whether it is a professional technician or an ordinary user, the filter can be easily maintained, greatly reducing the difficulty of operation and time cost. It also allows users to flexibly select appropriate filter components according to actual needs to achieve the best air purification effect, which not only improves maintenance efficiency but also extends the service life of the equipment.
