Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a sub-high efficiency filter. Background Technology

[0002] Sub-HEPA filters are air filters with performance between medium-efficiency and high-efficiency filters, suitable for many environments with specific air quality requirements. They offer good filtration while providing energy savings and cost-effectiveness, and are commonly found in air purification systems in various industrial, commercial, and public environments. The working principle of sub-HEPA filters is similar to other air filters, removing pollutants such as particulate matter, dust, and pollen from the air through physical means. When air passes through the filter media, particulate matter is captured, while clean air is discharged.

[0003] Existing filters generally do not have the ability to clean the mesh at the vents. They need to be removed and cleaned after dust accumulates, which is cumbersome and not easy to disassemble quickly. Therefore, a sub-high efficiency filter is proposed to address the above shortcomings.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example 1

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a sub-high efficiency filter, including a filter body 1, a fixing plate 2 fixedly connected inside the filter body 1, a support plate 3 fixedly connected to the outer surface of the fixing plate 2, a motor 4 fixedly connected to the upper surface of the support plate 3, a rotating shaft 5 fixedly connected to the output end of the motor 4, a cam 6 fixedly connected to the outer surface of the rotating shaft 5, inner grooves 7 opened on both sides inside the filter body 1, a damper 8 fixedly connected inside the inner groove 7, a connecting plate 9 fixedly connected to the output end of the damper 8, a connecting rod 10 fixedly connected to the outer surface of the connecting plate 9, and an extension plate fixedly connected to the lower surface of the connecting rod 10. 11. A scraper 12 is fixedly connected to the outer surface of the extension plate 11. A slot 13 is opened on the outer surface of the filter body 1. A rod 14 is inserted into the slot 13. A cover plate 15 is fixedly connected to the other end of the rod 14. A plurality of vents 16 are opened on the outer surface of the cover plate 15. The vents 16 are slidably connected to the scraper 12. A spring 19 is fixedly connected to the inside of the inner groove 7. The other end of the spring 19 is fixedly connected to the lower surface of the connecting plate 9. The output end of the motor 4 is rotatably connected to the inside of the fixed plate 2. The outer surface of the cam 6 abuts against the upper surface of the connecting rod 10. The outer surface of the connecting plate 9 is slidably connected to the inside of the inner groove 7.

[0026] In this embodiment, the output end of the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the cam 6 to rotate. When the large area of ​​the cam 6 rotates to the bottom, it will abut against the connecting rod 10, causing the connecting rod 10 to move downward. When it rotates back, the rebound effect of the damper 8 will cause the connecting rod 10 and the scraper 12 to rise and fall. The scraper 12 scrapes the vent 16 to remove external dust. The filter body 1 fixes the fixing plate 2, the fixing plate 2 fixes the support plate 3, the support plate 3 fixes the motor 4, the inner groove 7 fixes the damper 8 and the spring 19, the connecting plate 9 supports the connecting rod 10, the connecting rod 10 fixes the extension plate 11 and the scraper 12, and the spring 19 assists the operation of the damper 8. Example 2

[0027] like Figures 1-5 As shown, the slot 13 is internally threaded with a bolt 17, the outer surface of the bolt 17 is inserted into the inside of the insert rod 14, and the other end of the bolt 17 is threaded with a nut 18.

[0028] In this embodiment, the bolt 17 inside the slot 13 is rotated out, and the nut 18 is loosened to rotate the bolt 17, separating the bolt 17 from the insert rod 14. The insert rod 14 and the cover plate 15 can then be removed from the outer surface of the filter body 1.

[0029] The working principle of this embodiment is as follows: The motor 4 on the upper surface of the support plate 3 is activated. The output of the motor 4 drives the rotating shaft 5 to rotate, which in turn drives the cam 6 to rotate. When the large area of ​​the cam 6 rotates to the bottom, it abuts against the connecting rod 10, causing the connecting rod 10 to move downwards. Upon returning to its original position, the damper 8's rebound effect causes the connecting rod 10 and the scraper 12 to rise and fall. The scraper 12 scrapes away dust from the vent 16. When the cover plate 15 needs to be removed, the bolts 17 inside the slot 13 can be removed. Rotate to loosen nut 18 and then rotate bolt 17 to separate bolt 17 from insert rod 14. Insert rod 14 and cover plate 15 can then be removed from the outer surface of filter body 1. Fixing plate 2 is fixed by filter body 1, support plate 3 is fixed by fixing plate 2, motor 4 is fixed by support plate 3, damper 8 and spring 19 are fixed by inner groove 7, connecting rod 10 is supported by connecting plate 9, extension plate 11 and scraper 12 are fixed by connecting rod 10, and spring 19 assists in the operation of damper 8.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
