Description

Technical Field

[0001] The utility model belongs to the technical field of formaldehyde removal activated carbon filter screens, and particularly relates to an ultra-thin formaldehyde removal activated carbon filter screen. Background Art

[0002] The formaldehyde removal activated carbon filter is an air purifier component designed to remove volatile organic compounds (VOCs) such as formaldehyde from indoor air. It is mainly made of activated carbon material, and uses the porous structure and high surface area characteristics of activated carbon to capture and adsorb formaldehyde molecules and other harmful gases in the air through physical adsorption. The ultra-thin formaldehyde removal activated carbon filter is a filter that has a significantly reduced thickness while maintaining high-efficiency formaldehyde removal performance. This design is intended to meet the needs of modern air purifiers for compactness, lightness, and high efficiency, so that the filter can provide sufficient adsorption capacity in a limited space without affecting the overall size and airflow efficiency of the equipment. The existing ultra-thin formaldehyde removal activated carbon filter cannot be quickly disassembled from the frame, which is not conducive to personnel maintenance of the activated carbon filter plate.

[0003] For example, the utility model with publication number CN218249395U discloses an ultra-thin activated carbon filter for removing formaldehyde. In this patent scheme, the activated carbon filter unit used for removing formaldehyde cannot be quickly disassembled from the frame. The inability to quickly disassemble means that more steps and time are required to replace the activated carbon filter unit, which increases the complexity and time-consuming of daily maintenance for users. Frequent or complicated disassembly and assembly processes may reduce user satisfaction with the product, especially when the activated carbon filter unit needs to be regularly inspected or cleaned to maintain purification efficiency. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides an ultra-thin formaldehyde removal activated carbon filter. The quick disassembly design simplifies the replacement process of the activated carbon filter plate. Users can easily operate it by themselves without the need for professional tools or assistance from technicians, saving time and energy.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an ultra-thin formaldehyde-removing activated carbon filter, comprising a frame, an activated carbon filter plate is arranged inside the frame, a plurality of sliding holes opened on the upper and lower sides of the frame are slidably connected with locking columns, a plurality of locking holes are opened on the upper and lower sides of the activated carbon filter plate, four locking columns are respectively plugged into adjacent locking holes, a linkage mechanism is arranged at one end of the four locking columns close to the horizontal center of the frame, a protective component is arranged on the rear side of the frame, and the linkage mechanism includes a Connecting column, one end of the four connecting columns close to the horizontal center of the frame is provided with a slide groove frame, sliding cylinders are provided at the left and right ends of the front side of the frame, the interiors of the two slide cylinders are slidably connected with sliding columns, and sliding column plates are provided on the front side surfaces of the two sliding columns. The two upper and lower adjacent slide groove frames are respectively slidably connected to a sliding column plate, an elastic driving unit is provided between the sliding cylinder and the sliding column plate, the elastic driving unit includes a spring arranged between the sliding cylinder and the sliding column plate, the two springs are respectively sleeved on the outer arc surfaces of the corresponding sliding columns, and a plurality of anti-slip protrusions with equal intervals are provided on the front side surfaces of the sliding column plate.

[0006] As a further improvement of the present invention, two mounting plates are respectively arranged on the left and right sides of the frame, and two mounting holes are provided inside the four mounting plates.

[0007] As a further improvement of the utility model, the protective component includes a filter screen plate arranged on the rear side of the frame, the filter screen plate is located on the rear side of the activated carbon filter plate, and a scraper cleaning unit is arranged on the rear side of the frame. The scraper cleaning unit includes a scraper brush frame slidably arranged on the rear side of the frame, and the front side of the scraper brush frame is in contact with the filter screen plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, by installing the frame to a suitable position, impurities in the air can be filtered through the filter, and the air without impurities passes through the activated carbon filter plate to adsorb formaldehyde in the air. The filter plate filters the impurities, which can extend the service life of the activated carbon filter plate.

[0010] Secondly, by pressing the sliding column plates on both sides, the connecting columns on the slide slot frames on both sides move away from each other, and then the locking columns on both sides leave the locking holes opened in the activated carbon filter plate. At this time, the spring is in a compressed state, and then the personnel takes out the activated carbon filter plate, and then places the new activated carbon filter plate inside the frame so that its locking holes correspond to the positions of the locking columns. Then the sliding column plate is released. At this time, the spring rebounds quickly and drives the slide slot frames on both sides to move closer together, so that the locking columns on the connecting columns are inserted into the locking holes opened in the activated carbon filter plate, thereby realizing the quick disassembly and installation of the activated carbon filter plate. When pressing the sliding column plate, the anti-slip protrusions on the sliding column plate can prevent people from slipping when contacting the sliding column plate. The quick disassembly design simplifies the replacement process of the activated carbon filter mesh plate, and users can easily operate it by themselves without the need for professional tools or technical assistance, saving time and energy.

[0011] Thirdly, by pushing the scraper brush frame up and down, the dust and impurities on the surface of the filter screen can be scraped off, making it easier for personnel to clean the filter screen and making it more convenient for personnel to use.

[0012] Fourthly, the formaldehyde removal activated carbon filter can be quickly installed through the mounting holes on the mounting plate, which is convenient for personnel to install. BRIEF DESCRIPTION OF THE DRAWINGS
