Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air purification metal filter. Background Technology

[0002] In the existing field of air purification technology, metal filters and air purification devices have been widely used. Traditional metal filter designs typically employ multi-layer metal filter screens, using staggered arrangement of small holes or folding processing of the metal filter screen to capture dust and particulate matter in the air, thereby improving the purification effect. This type of design shows certain advantages in terms of durability and ease of cleaning. The rust-resistant properties of metal materials allow the filter to maintain good filtration performance during long-term use, and it is easy to clean, reducing the frequency of filter replacement, thereby reducing operating costs and improving environmental benefits.

[0003] Publication No. CN208003630U discloses a metal filter and air purification device, including: multiple layers of metal filter screens, each layer of metal filter screens having a plurality of small holes arranged in a staggered manner; or, including one or more layers of metal filter screens, wherein the metal filter screens are formed by folding a single piece of metal into a W-shaped zigzag pattern. The size of the small holes is set according to the size of the dust to be filtered. By staggering the arrangement of the small holes on different layers of metal filter screens, the dust capture rate is improved, and the purification effect is enhanced. The metal filter screens can be made of rust-resistant materials, such as copper, stainless steel, aluminum alloy, or other metal materials that have undergone rust-proofing treatment, which are both durable and easy to clean, eliminating the need to replace filter elements, saving costs, and being more environmentally friendly.

[0004] The above-mentioned problems still exist, specifically: relying solely on the small holes in the metal filter to capture dust may not be effective in removing fine particulate matter and harmful gases in the air, such as bacteria, viruses, pollen, dust mites, and harmful gases such as formaldehyde and benzene. The impact of these tiny pollutants on indoor air quality cannot be ignored. In addition, although traditional designs are relatively simple to clean and maintain, they lack an efficient and convenient cleaning mechanism. Operators need to manually clean the metal filter, which is not only time-consuming and labor-intensive, but may also affect the filtration effect due to incomplete cleaning.

[0005] In view of this, we have studied and improved the existing structure and its shortcomings, and provided an air purification metal filter to achieve a more practical purpose. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 An air purification metal filter includes a frame 1, a through groove in the center of the frame 1, a filter 3 installed inside the through groove, a frame cover 2 correspondingly provided at the upper end of the frame 1, an opening in the center of the frame cover 2 corresponding to the through groove, and through holes on the outer perimeter of the frame cover 2. The filter is characterized by further comprising:

[0027] The cleaning component has a fixing plate 6 inside the opening in the center of the frame cover 2. By moving the fixing plate 6 repeatedly, the surface of the filter 3 can be cleaned of dust.

[0028] Furthermore, limiting grooves 10 are respectively opened on the upper surface of the frame 1, and snap-fit ​​grooves are opened on one side inside the limiting grooves 10. Threaded holes 11 are respectively opened around the upper surface of the frame 1.

[0029] Furthermore, the filter 3 is composed of a precision metal mesh 12, a HEPA filter 13, an activated carbon filter 14, and a polymer odor filter 15. The polymer odor filter 15 is installed at the bottom of the channel. The activated carbon filter 14 is tightly attached to the top of the polymer odor filter 15. The HEPA filter 13 is tightly attached to the top of the activated carbon filter 14. The precision metal mesh 12 is tightly attached to the top of the HEPA filter 13.

[0030] Furthermore, bolts 4 are respectively fitted into the through holes opened around the frame cover 2, and mounting plates 5 are fixedly installed on the lower surface of the frame cover 2. A snap-fit ​​block is provided on one side of the lower end of the mounting plate 5. Sliding grooves are respectively opened on the inner opening surface of the frame cover 2.

[0031] Furthermore, the through holes opened around the frame cover 2 are respectively set to correspond to the threaded holes 11 opened around the frame 1, and the lower ends of the bolts 4 are all threaded into the inside of the threaded holes 11. The mounting plates 5 fixedly installed at the lower end of the frame cover 2 are respectively set to correspond to the limiting grooves 10 opened at the upper end of the frame 1, and the lower ends of the mounting plates 5 are respectively snapped into the inside of the limiting grooves 10.

[0032] Furthermore, the cleaning assembly comprises a convex plate 7, rollers 8, and a cleaning brush 9. The outer ends of the fixed plate 6 are respectively set inside the sliding grooves opened in the frame cover 2. Rollers 8 are installed at both ends of the fixed plate 6, and the outer ends of the rollers 8 are in sliding fit with the inside of the sliding grooves. The convex plate 7 is fixedly connected to the center of the upper surface of the fixed plate 6, and the cleaning brush 9 is fixedly installed on the lower surface of the fixed plate 6. The lower end of the cleaning brush 9 is in contact with the upper surface of the precision metal mesh 12.

[0033] Working Principle: First, the frame 1 serves as the main structure, with a central slot for installing the filter element 3. The frame cover 2 is fastened by bolts 4 engaging with the threaded holes 11 on the frame 1. The mounting plate 5 at the lower end of the frame cover 2 corresponds to the limiting groove 10 on the frame 1, and the snap-fit ​​block at the lower end of the mounting plate 5 engages in the snap-fit ​​groove, ensuring that the frame cover 2 is stably fixed to the frame 1. When air passes through the air purification metal filter, it first passes through the precision metal mesh 12, which blocks large particles in the air, such as dust, hair, and dander, preventing these impurities from entering subsequent filter layers, thereby extending the service life of the entire filter system. Following the precision metal mesh 12 is the HEPA filter 13, which effectively removes bacteria, viruses, pollen, dust mites, and other fine particles from the air, providing cleaner indoor air. The activated carbon filter 14 is located after the HEPA filter 13, and its main function is to adsorb harmful gases and odors in the air. Activated carbon, due to its porous structure, has a strong adsorption capacity and can adsorb formaldehyde. The filter removes harmful gases such as benzene and ammonia, as well as odors such as kitchen fumes and cigarette smoke, thereby further purifying the indoor air. Finally, the polymer odor filter 15 is mainly responsible for removing residual odors in the air. It can efficiently adsorb and decompose odor molecules in the air, making the indoor air fresher and more pleasant. When cleaning is required, the operator can move the convex plate 7 to drive the fixed plate 6 and its cleaning brush 9 to slide in the groove opened in the frame cover 2. The lower end of the cleaning brush 9 contacts the upper surface of the precision metal mesh 12. As the fixed plate 6 slides, the cleaning brush 9 can brush away the dust and impurities on the surface of the precision metal mesh 12. At the same time, the roller 8 rolls in the groove, reducing the friction when the fixed plate 6 slides, making the cleaning process smoother. When the filtration effect of the filter 3 decreases or reaches the end of its service life, the frame cover 2 can be opened and the filter 3 can be taken out for replacement. When replacing, simply loosen the bolt 4, remove the frame cover 2 from the frame 1, then take out the old filter 3, install the new filter 3, and re-fix the frame cover 2 according to the above steps.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
