[0023] The fixed frame 1 adopts a frame structure with a single-side opening. After the pressing component 23 presses and fixes the inner filter 3, the sliding frame 2 is pushed in and fixed along the opening side of the fixed frame 1. The first magnetic member 12 and the second magnetic member 26 cooperate with magnetic adsorption to quickly position and install the fixed frame 1 and the sliding frame 21. The detachable installation frame 22 structure adopts a card block 25 and a card slot 24 on one side of the sliding frame 21 to guide the connection and installation. The sliding disassembly and magnetic positioning installation method are simple and efficient, which improves the disassembly and assembly efficiency. When the inner filter 3 needs to be cleaned, the sliding frame 2 is pulled out and the two sets of pressing blocks 233 are moved to both sides. Push it open to deeply clean the inner filter 3. The clamping assembly 23 arranged in the installation frame 22 adopts an elastic pre-compression method to pre-position the inner filter 3. During the pushing process, several rollers 16 arranged on the inner wall of the fixed frame 1 apply downward pressure to the several pressing blocks 233 of the pressure plate 231. When the sliding frame 2 is fully pushed in and magnetically fitted with the fixed frame 1, the pressure plate 231 is clamped and positioned in the fixed middle part with the cooperation of several rollers 16 and several pressing blocks 233. During ventilation and filtration, the inner filter 3 will not be affected by the airflow and shake to form abnormal noise.

[0024] In this embodiment, the fixed frame 1 is formed with a ventilation slot 13 and two groups of protruding sections 14. The ventilation slot 13 is arranged in the middle of the fixed frame 1. The ventilation slot 13 is fixedly connected to the protective grille 11. The middle of the two groups of protruding sections 14 are provided with a guide slot 15. Each of the guide slots 15 corresponds to the corresponding mounting frame 22 for sliding cooperation. The protruding sections 14 correspond to the corresponding sliding frames 21 and are provided with a plurality of first magnetic parts 12. The two groups of protruding sections 14 are formed with an inclined surface. The sliding frame 21 is provided with a mounting wall that fits the inclined surface. The first magnetic part 12 is a magnet, which is installed and disassembled by magnetic adsorption. The structure is simple and easy to use, simplifies the disassembly and installation process, and is highly practical. The protective grille 11 is a coarse mesh aluminum grille, which is used to prevent foreign objects from directly colliding with the inner filter 3, thereby improving the safety and effectiveness of use.

[0025] In this embodiment, the sliding frame 21 is provided with a plurality of second magnetic parts 26, and the plurality of second magnetic parts 26 are respectively provided at both ends of the sliding frame 21. The plurality of second magnetic parts 26 correspond to the corresponding plurality of first magnetic parts 12 for magnetic attraction and cooperation. The second magnetic parts 26 are in the shape of long strips and are embedded in the inner sides of the two ends of the sliding frame 21.

[0026] In this embodiment, the inner walls on both sides of the fixed frame 1 are rotatably connected to a plurality of rollers 16 along the entry path of the sliding frame 2. Each of the rollers 16 is pressed and fitted with the corresponding clamping assembly 23. The roller 16 is provided with a rotating shaft and a pad. The rotating shaft is fixedly connected to the inner wall of the fixed frame 1. The roller 16 is sleeved on the rotating shaft, and the rotating shaft is set between the roller 16 and the inner wall of the fixed frame 1 to limit the forward and backward movement position of the roller 16.

[0027] In this embodiment, the pressing assembly 23 includes a pressing plate 231 and a plurality of elastic members 232 provided at the upper and lower ends of the mounting frame 22. The first end of each elastic member 232 is connected to the inner wall of the mounting frame 22, and the second end of each elastic member 232 is connected to the first surface of the pressing plate 231 on the same side. Each pressing plate 231 is provided with a plurality of pressing blocks 233 and a plurality of pressing columns 234. The plurality of pressing blocks 233 are provided on the side of the pressing plate 231. 33 corresponds to the corresponding roller 16, and the plurality of pressure columns 234 are arranged on the second surface of the pressure plate 231 and are connected to one end of the inner filter 3. The elastic member 232 is a compression spring. The two groups of pressure plates 231 are symmetrically arranged at the upper and lower inner walls of the mounting frame 22. The plurality of elastic members 232 are correspondingly connected to the upper and lower inner walls of the mounting frame 22. The plurality of elastic members 232 provide elastic support force to the two groups of pressure plates 231, and provide pre-tightening force after the inner filter 3 is placed, cooperating with the plurality of pressure columns on the pressure plate 231. 234 limits the forward and backward movement of the inner filter screen 3. Several pressure columns 234 are arranged at equal intervals on the second surface of the pressure plate 231 to press the inner filter screen 3 to prevent it from moving forward and backward. The pressure block 233 is an extension part and a downward pressure part. The upper end of the extension part is connected to the side wall of the pressure block 233, and the downward pressure part is connected to the lower end of the extension part. The extension part is limited by the reserved groove 221 of the installation frame 22, thereby limiting the maximum rising height and maximum falling height of the pressure plate 231. The upper and lower surfaces of the downward pressure part are arc-shaped, and the upper surface of the downward pressure part is connected to the roller 16. The lower surface of the pressing part cooperates with the stop groove 223 of the slide groove 222. When the inner filter screen 3 is put in and clamped, the inner filter screen 3 supports two sets of pressure plates 231, and the several elastic members 232 on the upper and lower sides are in a compressed state. The pressure blocks 233 on the upper and lower sides are in a state of being away from each other. When the fixed frame 1 is pushed in, the roller 16 contacts the upper surface of the pressure block 233 and applies downward pressure. Under the action of the downward pressure, the pressure plate 231 squeezes the inner filter screen 3 from the upper and lower sides, further pressing and fixing the position of the inner filter screen 3 to limit its displacement.

[0028] In this embodiment, the mounting frame 22 is formed with a plurality of reserved grooves 221 arranged on the side wall and a slide groove 222 arranged on the outer side surface. Each of the reserved grooves 221 corresponds to and cooperates with the corresponding pressure block 233 to limit the position. The slide groove 222 is formed with a stop groove 223. The stop groove 223 is supported and cooperated with a plurality of the pressure blocks 233, and the stop groove 223 is an arc surface.

[0029] In this embodiment, the inner filter 3 is a multi-layer folded aluminum mesh structure. The multi-layer folding design increases the filtration area and improves the filtration efficiency while maintaining low wind resistance. It effectively removes larger particles in the air without significantly increasing energy consumption.

[0030] The working principle of this utility model:

[0031] The two sets of mounting frames 22 are respectively installed at the two ends of the sliding frame 21 under the guidance of the card block 25, and then the sliding frame 2 is pushed into the sliding frame 2 along the opening side of the fixed frame 1. The upper and lower outer walls of the mounting frame 22 slide with the inner wall of the fixed frame 1, and the slide groove 222 passes through the guide groove 15 of the extended section 14 of the fixed frame 1. When the fixed frame 1 is pushed in, the roller 16 contacts the upper surface of the pressing block 233 and applies downward pressure. The pressing plate 231 squeezes the inner filter screen 3 from the upper and lower sides under the action of the downward pressure, further pressing and fixing the position of the inner filter screen 3 to limit the displacement of the inner filter screen 3. When the fixed frame 1 and the sliding frame 21 are close to each other, the first magnetic members 12 and the second magnetic members 26 attract each other, so that the sliding frame 21 and the fixed frame 1 are tightly attached to each other under the action of the magnetic attraction, and the installation is completed.

[0032] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
