Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridges, in particular to a filter cartridge for air filtration. Background Art

[0002] A filter cartridge is a cylindrical element used for filtering. It is generally divided into filter cartridges for filtering gaseous media and filtering liquid media. The air filter cartridge can allow air to pass into the filter cartridge. The filter mesh and filter paper inside the filter cartridge can filter out dust and other impurities in the air, achieving an air purification effect.

[0003] For example, the utility model: "A filter cartridge for air filtration", with the announcement number: "CN214715212U", is provided with multiple deformable filter areas on the filter cartridge body. In the absence of airflow, the filter cartridge body returns to the filtering state driven by the deformable filter areas. The cleaning process is simple and the filter cartridge body is not easily damaged. However, during the implementation of the patent, it is only reinforced by a support ring and a protective net. When the outer side of the filter cartridge is squeezed, the filter paper cannot be effectively protected, making the filter paper easily squeezed and deformed. After the filter paper is damaged, it is not convenient to remove the filter paper and other parts from the filter cartridge for replacement. Therefore, the research and development of new filter cartridges for air filtration has received more and more attention from researchers. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the utility model provides an embodiment: a filter cartridge for air filtration, comprising a mounting circular plate 1, a circular filter screen 2 and a reinforcement mounting piece 4, a filter cartridge filter paper 3 is mounted on the outside of the circular filter screen 2, and mounting circular plates 1 are mounted on both ends of the circular filter screen 2, a group of first mounting slots 8 are symmetrically provided on one end of the mounting circular plate 1 close to the circular filter screen 2, two groups of reinforcement mounting pieces 4 are mounted on one end of the mounting circular plate 1 close to the circular filter screen 2, and second mounting plug-ins 11 are mounted on both ends of the reinforcement mounting piece 4, and a group of first mounting plug-ins 9 are symmetrically mounted on both ends of the circular filter screen 2. During installation, the first mounting plug-ins 9 at both ends of the circular filter screen 2 can be inserted into the first mounting slots 8 provided on the two groups of mounting circular plates 1, and the circular filter screen 2 and the filter cartridge filter paper 3 can be installed between the two groups of mounting circular plates 1.

[0023] like Figure 1-4 As shown, the outer side of the second mounting plug 11 is provided with a mounting groove 13, and the interior of the mounting groove 13 is provided with a fixing spring 10, and the outer side of the fixing spring 10 is provided with an anti-rust layer, and the end of the fixing spring 10 away from the second mounting plug 11 is provided with a fixing block 7, and the end of the mounting circular plate 1 close to the circular filter screen 2 is symmetrically provided with a group of second mounting slots 12, and the outer side of the mounting circular plate 1 is symmetrically provided with a group of fixing slots 14, and the fixing slots 14 are all connected with the mounting groove 13. The second mounting plug 11 is inserted into the second mounting slot 12 so that the fixing block 7 is stuck in the fixing slot 14, and the reinforcement mounting piece 4 can be fixed, and the circular filter screen 2 and the filter cartridge filter paper 3 can be firmly installed between the two groups of mounting circular plates 1. The fixing block 7 is removed from the fixing slot 14, and the reinforcement mounting piece 4 and the mounting circular plate 1 can be separated, and the circular filter screen 2 and the filter cartridge filter paper 3 can be removed separately from between the two groups of mounting circular plates 1.

[0024] like Figure 1-3As shown, semicircular reinforcement pieces 5 are evenly installed on the outside of the reinforcement mounting pieces 4, and reinforcement connecting pieces 6 are evenly installed on the outside of the semicircular reinforcement pieces 5, and two adjacent groups of semicircular reinforcement pieces 5 are connected by reinforcement connecting pieces 6. When in use, the outside of the filter cartridge filter paper 3 can be protected by the reinforcement mounting pieces 4, semicircular reinforcement pieces 5 and reinforcement connecting pieces 6, so that objects cannot be directly squeezed onto the filter cartridge filter paper 3, thereby preventing the circular filter screen 2 and the filter cartridge filter paper 3 from being deformed by force and avoiding the filter cartridge filter paper 3 from being crushed.

[0025] Working principle:

[0026] During installation, the first mounting plugs 9 at both ends of the circular filter screen 2 can be inserted into the first mounting slots 8 provided on the two sets of mounting circular plates 1, and the circular filter screen 2 and the filter paper cartridge 3 can be installed between the two sets of mounting circular plates 1. Then, the second mounting plugs 11 at both ends of the reinforcement mounting plate 4 can be inserted into the second mounting slots 12 provided on the two sets of mounting circular plates 1.

[0027] When the fixed block 7 on the second mounting block 11 moves to a position facing the fixed slot 14, the elastic action of the fixing spring 10 pushes the fixed block 7 to move, and the fixed block 7 can be clamped into the fixed slot 14. The fixed block 7 limits the second mounting block 11, preventing the second mounting block 11 from moving further, and thus the reinforcement mounting piece 4 is fixed to the mounting circular plate 1, completing the installation process;

[0028] During use, the outer side of the filter paper 3 of the filter cartridge can be protected by the reinforcement mounting piece 4, the semicircular reinforcement piece 5 and the reinforcement connecting piece 6, so that objects cannot be directly pressed onto the filter paper 3 of the filter cartridge, thereby preventing the circular filter screen 2 and the filter paper 3 from being deformed by force and avoiding the filter paper 3 of the filter cartridge from being crushed;

[0029] After use, the fixing block 7 can be pressed out from the fixing slot 14 to release the restriction of the fixing block 7 on the second mounting block 11, so that the second mounting block 11 can be moved, thereby separating the mounting circular plate 1 and the reinforcement mounting piece 4;

[0030] Then, the first mounting plug 9 is removed from the first mounting slot 8 to separate the circular filter screen 2 and the filter cartridge filter paper 3 from the mounting circular plate 1 . The circular filter screen 2 and the filter cartridge filter paper 3 can be removed separately for cleaning and replacement.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
