Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a magnetically attached, quick-release air filter structure. Background Technology

[0002] Most air filters on the market currently use traditional mechanical fixing methods, mainly including three structures: snap-on, screw-fastening, and sliding rail. These fixing methods have many limitations in actual use: In terms of ease of disassembly and assembly, snap-on designs require both hands to disassemble, screw-fastening requires special tools such as screwdrivers, and sliding rail structures often require precise alignment with the rail for installation. These procedures are not only cumbersome and time-consuming, but also increase the difficulty of daily maintenance. In terms of durability, after repeated disassembly and assembly, plastic snaps are prone to fatigue deformation or even breakage, resulting in gaps between the filter and the equipment frame, seriously affecting the sealing effect. In terms of maintenance efficiency, the complex fixing structure requires complete disassembly for each cleaning, and it is difficult to thoroughly clean the dust accumulated inside the fixing mechanism. These structural defects directly affect the user experience and the long-term performance of the filtration system. Utility Model Content

[0003] The main purpose of this invention is to provide a magnetically attached, quick-release air filter structure, which aims to improve installation and disassembly efficiency, provide good sealing, and facilitate maintenance.

[0004] To achieve the above objectives, this utility model proposes a magnetically attached, quickly detachable air filter structure, comprising:

[0005] A filter screen has a mounting surface and an outer surface. The filter screen includes an edge frame and a plurality of filter strips disposed within the edge frame. A magnet is disposed on the mounting surface of the edge frame.

[0006] The fan body has a back cover, and the edge of the back cover is provided with a magnetic material corresponding to the magnet so that the filter screen is attracted to the back cover.

[0007] In one possible implementation, the edge frame is provided with a plurality of mounting slots spaced apart on the mounting surface, and the magnet is detachably disposed within the mounting slots.

[0008] In one possible implementation, the edge frame has a positioning strip protruding from the mounting surface, and the edge of the back cover has a positioning groove corresponding to the positioning strip.

[0009] In one possible implementation, a plurality of reinforcing ribs are also provided at intervals within the edge frame.

[0010] This utility model's technical solution employs a magnetic fixing structure, with detachable permanent magnet modules spaced at intervals along the filter screen frame. These modules form a strong attraction with the magnetic material on the equipment frame, enabling quick assembly and disassembly with just one hand. Combined with a self-sealing design, the magnetic force tightly presses the filter screen edges against the back cover, effectively preventing airflow leakage. Positioning strips and grooves on the frame precisely match, ensuring automatic alignment during installation and eliminating the possibility of misinstallation. Simultaneously, the rational arrangement of reinforcing ribs significantly enhances the frame's rigidity, preventing deformation and cracking. The modular design allows for independent replacement of the magnets, greatly extending service life and reducing maintenance costs. Attached Figure Description

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Reference Figures 1 to 3This utility model proposes a magnetically attached, quick-release air filter structure, including a filter sheet 1 and a fan body 5. The filter sheet 1 has a mounting surface and an outer surface. The filter sheet 1 includes an edge frame 2 and multiple filter strips 3 disposed within the edge frame 2. The edge frame 2 has a magnet 4 disposed on the mounting surface. The fan body 5 has a back cover 6. The edge of the back cover 6 is provided with a magnetically conductive material 7 corresponding to the magnet 4, so that the filter sheet 1 is attracted to the back cover 6.

[0020] Understandably, the edge frame 2 is the outer structure of the filter 1, used to support and fix the internal filter strips 3. Multiple filter strips 3 are arranged inside the edge frame 2, responsible for air filtration. The magnet 4 is installed on the mounting surface of the edge frame 2 for adsorption and fixation. The rear cover 6 is the back cover of the fan, and its edge area corresponds to the position of the edge frame 2 of the filter 1. The edge of the rear cover 6 is provided with a material such as an iron sheet that can be attracted by the magnet 4, so that the filter 1 can be firmly adsorbed onto the fan.

[0021] The filter screen 1 is fixed to the fan back cover 6 by the attraction between the magnet 4 and the magnetic material 7, without the need for screws or clips. When disassembly is required, simply pull it open to achieve quick disassembly and assembly, making it convenient for cleaning or replacing the filter screen and eliminating the complicated steps of traditional fixing methods. At the same time, the magnetic design ensures that the filter screen 1 fits tightly, preventing air leakage or displacement, making it suitable for scenarios requiring frequent cleaning.

[0022] Reference Figure 2 In one embodiment of this utility model, the edge frame 2 is provided with a plurality of mounting grooves 21 spaced apart on the mounting surface, and the magnet 4 is detachably disposed in the mounting grooves 21.

[0023] Understandably, the mounting surface of the edge frame 2 has multiple mounting slots 21 spaced apart for placing the magnet 4. The mounting slots 21 can be recesses, grooves, or slots to ensure the magnet 4 is securely embedded and not easily detached. The magnet 4 is not fixed in place but is detachably embedded in the mounting slots 21, such as through snap-fit, elastic fixing, or simple embedding (in this example, embedding). This facilitates the replacement of damaged magnets 4 and extends the lifespan of the filter screen 1.

[0024] Reference Figures 2 to 3 In one embodiment of this utility model, the edge frame 2 is provided with a positioning strip 22 protruding on the mounting surface, and the edge of the back cover 6 is provided with a positioning groove 61 corresponding to the positioning strip 22.

[0025] Understandably, the positioning strip 22 is located on the mounting surface of the edge frame 2 of the filter screen 1. Its shape can be a raised strip, wedge, cylinder, etc., with a certain height and width, which can play a guiding role and help users quickly align the filter screen 1 and the fan back cover 6 to avoid installation backwards or offset; it can also prevent misalignment and prevent the filter screen 1 from sliding laterally due to external forces such as vibration or airflow after it is adsorbed.

[0026] The positioning groove 61 is located on the edge of the fan back cover 6. Its shape is a groove or notch that matches the positioning strip 22 to ensure a tight fit. It works with the positioning strip 22 to ensure that the filter screen 1 can only be installed in a fixed direction and cannot be rotated or misaligned. It works in conjunction with the magnetic structure to reduce the risk of the filter screen 1 becoming loose.

[0027] Reference Figure 2 In one embodiment of this utility model, a plurality of reinforcing ribs 23 are also provided at intervals within the edge frame 2.

[0028] Understandably, the reinforcing ribs 23 are located inside the edge frame 2 and are arranged radially with the filter strips 3 at intervals, connecting the two sides of the frame. This prevents the edge frame 2 from deforming due to external forces such as pressing or handling, and protects the internal filter strips 3. It also reduces the risk of local frame breakage when the filter is subjected to airflow impact or frequent disassembly and assembly.

[0029] The reinforcing rib 23 does not interfere with the installation of the magnet 4 and the positioning strip 22, but it will improve their load-bearing stability. If the filter strip 3 is made of flexible material, the reinforcing rib 23 can help fix its position.

[0030] This utility model's technical solution employs a magnetic fixing structure, with detachable permanent magnet modules 4 spaced at intervals along the filter screen frame. These modules form a strong attraction with the magnetically conductive material 7 on the equipment frame, enabling quick assembly and disassembly that can be completed with one hand. Combined with a self-sealing design, the magnetic force tightly presses the filter screen edge against the back cover 6, effectively preventing airflow leakage. Positioning strips 22 and positioning grooves 61 on the frame precisely match, ensuring automatic alignment during installation and eliminating the possibility of misinstallation. Simultaneously, the rational arrangement of the reinforcing ribs 23 significantly enhances the frame's rigidity, preventing deformation and cracking. The modular design allows for independent replacement of the magnets 4, greatly extending service life and reducing maintenance costs.
