[0002] Air filtration device, usually referred to as air filter, is a device that captures dust from gas-solid two-phase flow through porous filter materials and purifies the gas. This type of device is widely used in clean workshops, clean factories, laboratories, clean rooms, and electronic machinery and communication equipment for dust prevention, anti-toxicity and air purification;

[0003] Nowadays, most air filter devices filter the air through the air filter materials inside them. However, as the filter materials inside them continue to filter the air, a large amount of impurities will be adsorbed on the filter materials. These impurities are easy to get stuck in the mesh of the filter materials after long-term use, causing blockage of the filter materials, thereby affecting their filtering effect. Therefore, during the use of the air filter device, the user is required to regularly clean or replace the filter materials inside it. However, the filter materials in traditional air filter devices mostly require specific steps and tools to disassemble and replace. In the process of disassembling and replacing the filter materials, the user needs to touch the internal components of the equipment and may face safety risks such as electric shock and scratches, which makes the disassembly and replacement of the filter materials more difficult.

Through the installation of the shell 6 and the positioning frame 7, the filter plate 8 can be more conveniently removed from the filter device, and the disassembly and assembly of the filter plate 8 can be faster, making it very easy to replace the filter plate 8 without disassembling the entire device, thereby improving the replacement efficiency of the filter plate 8 and avoiding safety risks such as electric shock and scratches that may occur to users during the replacement process, thereby improving the safety and practicality of the air filter device.

[0023] See also Figure 1 and Figure 2A dustproof net 3 is embedded inside the air inlet 2, and an exhaust fan 5 is fixed inside the air outlet 4. The dustproof net 3 located inside the air inlet 2 can effectively prevent large particles, dust and other impurities in the air from entering the inside of the machine body 1, thereby reducing the burden on the filter plate 8 and extending its service life. When the exhaust fan 5 is started, it will generate a certain suction force to discharge the air inside the machine body 1 through the air outlet 4. At the same time, since the air inlet 2 is connected to the external environment, the external air will be sucked into the machine body 1 under the action of the pressure difference, and will be discharged by the exhaust fan 5 after being filtered by the filter plate 8, thereby forming a complete air filtration cycle.

[0024] See also Figure 4 and Figure 5 , two sets of first lead screws 9 are rotatably arranged inside the housing 6, a lead screw nut 10 is meshed on the first lead screw 9, and the outside of the lead screw nut 10 is fixedly connected to the outside of the positioning frame 7 through a connecting piece, a first gear 11 is fixedly arranged on the first lead screw 9, a rotating rod 12 is rotatably arranged inside the housing 6, both ends of the rotating rod 12 are fixedly arranged with a second gear 13, and the second gear 13 is meshed with the first gear 11, a first gear 14 is fixedly arranged on the rotating rod 12, a driving motor 15 is fixedly arranged on the outside of the housing 6, a second gear 16 is fixedly arranged on the output end of the driving motor 15, and the second gear 14 is meshed with the first gear 11. The wheel 16 is located inside the shell 6 and meshes with the No. 1 gear 14. The filter plate 8 is limitedly installed inside the positioning frame 7. The drive motor 15 is electrically connected to the external power supply. When the drive motor 15 is working, the rotational force is transmitted to the rotating rod 12 through the meshing of the No. 2 gear 16 and the No. 1 gear 14. When the rotating rod 12 rotates, the second gears 13 at both ends thereof are meshed with the first gear 11 to drive the two groups of first lead screws 9 to rotate. Finally, the rotation of the first lead screw 9 is converted into a linear movement of the positioning frame 7 through the lead screw nut 10. As the positioning frame 7 moves, it will drive the filter plate 8 inside it to move out from the inside of the body 1.

[0025] See also Figure 4 and Figure 6Two groups of slots 24 are arranged inside the positioning frame 7, and a mounting frame 17 is arranged inside the slot 24 for movable positioning. A plurality of positioning members 18 are fixedly arranged on the mounting frame 17, and a rubber pad 19 is arranged at the positioning end of the positioning member 18. A magnetic attraction plate 20 is fixedly arranged outside the mounting frame 17, and an electromagnet 21 is fixedly arranged inside the slot 24, and the electromagnet 21 can cooperate with the magnetic attraction plate 20. A plurality of groups of springs 22 are fixedly arranged inside the slot 24, and one end of the spring 22 is fixed to one end of the mounting frame 17. The filter plate 8 is fixedly connected to the outside of the surface, and multiple groups of taking slots 23 are arranged on the positioning frame 7. The electromagnet 21 is electrically connected to the external power supply. When the staff manually places the filter plate 8 in the positioning frame 7, when the electromagnet 21 is energized, it will generate magnetism to attract the magnetic plate 20, so that the mounting frame 17 with limited movement in the slot body 24 moves and is fixed to the outside of the electromagnet 21. In this process, multiple groups of springs 22 will contract and store force. As the mounting frame 17 moves, one end of the external positioning member 18 equipped with the rubber pad 19 will The filter plate 8 is in contact with the outside of the filter plate 8 by the installation of the rubber pad 19, so that the positioning member 18 will not cause damage to the outside of the filter plate 8 during the contact with the filter plate 8, and the positioning member 18 improves the tightness of the positioning of the filter plate 8, so that the filter plate 8 can be fixed to the inside of the positioning frame 7 through multiple groups of positioning members 18. When the electromagnet 21 is powered off, the spring 22 will push the mounting frame 17 to return to its original position through the reset force, so that the positioning member 18 releases the positioning effect of the filter plate 8 on the positioning frame 7. The setting of the taking groove 23 provides enough space, allowing the user to contact the outside of the filter plate 8 on the positioning frame 7 with his fingers and remove it from the positioning frame 7, so that the filter plate 8 can be installed in the positioning frame 7 or taken out from the positioning frame 7 more quickly, and cooperates with the housing 6 that can move the positioning frame 7 out of the body 1, so that the replacement of the filter plate 8 becomes very simple, without the need to disassemble the entire device, thereby improving the replacement efficiency of the filter plate 8 and avoiding the safety risks of electric shock, scratches, etc. that may occur to the user during the replacement process, thereby improving the safety and practicality of the air filtering device.

[0026] Working principle: the body 1 is the main structure of the entire filtering device. The air inlet 2 and the air outlet 4 are respectively located at the two ends of the body 1, ensuring that the air can smoothly enter and flow out of the device. The filter plate 8 is the core component of the filtering device, responsible for intercepting dust, particles and other impurities in the air. Through the installation of the shell 6 and the positioning frame 7, the filter plate 8 can be more conveniently removed from the filtering device, and the disassembly and assembly of the filter plate 8 can be faster, making it very easy to replace the filter plate 8 without disassembling the entire device, thereby improving the replacement efficiency of the filter plate 8 and avoiding safety risks such as electric shock and scratches that may occur to users during the replacement process, thereby improving the safety and practicality of the air filtering device. The dustproof net 3 located in the air inlet 2 can effectively block large particles in the air. Impurities such as dust enter the body 1, thereby reducing the burden on the filter plate 8 and extending its service life. When the exhaust fan 5 is started, it will generate a certain suction force to discharge the air inside the body 1 through the air outlet 4. At the same time, since the air inlet 2 is connected to the external environment, the external air will be sucked into the body 1 under the action of the pressure difference, filtered by the filter plate 8 and then discharged by the exhaust fan 5, thus forming a complete air filtration cycle. The filter plate 8 is limitedly installed inside the positioning frame 7, and the drive motor 15 is electrically connected to the external power supply. When the drive motor 15 is working, the rotation force is transmitted to the rotating rod 12 through the meshing of the second gear 16 and the first gear 14. When the rotating rod 12 rotates, the second gear 13 at both ends thereof is meshed with the first gear 11 to drive the The two groups of first lead screws 9 are driven to rotate. Finally, the rotation of the first lead screw 9 is converted into a linear movement of the positioning frame 7 through the lead screw nut 10. As the positioning frame 7 moves, it will drive the filter plate 8 inside it to move out from the inside of the machine body 1. The electromagnet 21 is electrically connected to the external power supply. When the staff manually limits the filter plate 8 to be placed inside the positioning frame 7, when the electromagnet 21 is energized, it will generate magnetism to attract the magnetic plate 20, so that the mounting frame 17 with limited movement in the slot 24 moves and is fixed to the outside of the electromagnet 21. In this process, multiple groups of springs 22 will contract and store force. As the mounting frame 17 moves, one end of its external positioning piece 18 equipped with a rubber pad 19 will contact the outside of the filter plate 8. The installation of the rubber pad 19 enables the positioning piece 18 to be in contact with the filter plate 8. The filter plate 8 can be fixed to the inside of the positioning frame 7 through multiple sets of positioning members 18. When the electromagnet 21 is powered off, the spring 22 pushes the mounting frame 17 back to its original position through the reset force, so that the positioning member 18 releases the positioning effect of the filter plate 8 on the positioning frame 7. The setting of the taking groove 23 provides enough space, allowing the user to contact the outside of the filter plate 8 on the positioning frame 7 with his fingers and remove it from the positioning frame 7, so that the filter plate 8 can be installed in the positioning frame 7 or removed from the positioning frame 7 more quickly. In combination with the housing 6 that can move the positioning frame 7 out of the machine body 1, it is very easy to replace the filter plate 8 without disassembling the entire device.The replacement efficiency of the filter plate 8 is improved, and the safety risks such as electric shock and scratches that may occur to the user during the replacement process are avoided, thereby improving the safety and practicality of the air filtering device.
