[0029] In the present embodiment, through the mutual installation cooperation between the set positioning component 4 and the filter component 5, in actual use, the set positioning component 4 can quickly disassemble and assemble the filter component 5, and the clamping installation of the filter component 5 can be achieved by surrounding and clamping the positioning column 52 with a plurality of clamping plates 44; the filter component 5 can be used to filter the exhaust gas discharged from the ventilator body 2. Compared with the installation method in the cited document, the present application uses a quickly disassembled filter component 5 to enable maintenance personnel to replace and maintain the filter component 5 and the ventilator body 2 at the same position at the same time, thereby simplifying the maintenance process and facilitating the rapid replacement of the filter element in the filter component 5.

[0030] Furthermore, through the mutual movement and coordination of multiple components within the positioning assembly 4, in actual use, the clamping plate 44 extending around the center of the positioning disk 41 can be used to surround and install filter assemblies 5 of different sizes, thereby achieving installation and use that adapts to ventilator bodies 2 of different sizes, thereby improving the overall installation adaptation range.

[0031] Specifically, refer to Figure 2-4 The two ends of the filter cartridge 51 are open and the top filter screen 54 and the bottom filter screen 53 are respectively embedded in the upper and lower ends.

[0032] In this embodiment, in actual use, the bottom filter 53 and the top filter 54 can form a double-layer filter barrier to improve the overall filtering efficiency of the filter assembly 5 on the exhaust gas in the ventilator body 2; in a preferred embodiment, Figure 3 As shown in the figure, the exhaust gas entering the filter cartridge 51 can first pass through the bottom filter 53, and larger particles will be intercepted, thereby reducing the burden of clogging of the activated carbon particle layer 55 during use, thereby extending the service life of the activated carbon particle layer 55; further, the set top filter 54 can be used to prevent dust and impurities in the external well from clogging the filter cartridge 51.

[0033] Specifically, refer to Figure 3-4 The bottom filter screen 53 and the top filter screen 54 are detachably arranged on the outside of the filter cartridge 51 through a plurality of sets of hexagon socket bolts.

[0034] In this embodiment, by providing quick disassembly and assembly between the bottom filter 53 and the top filter 54, in a preferred embodiment, the hexagon socket bolts can provide a greater fastening force for the installation of the bottom filter 53 and the top filter 54, ensuring that the bottom filter 53 and the top filter 54 are firmly fixed on the filter cartridge 51, reducing loosening caused by vibration or pressure changes.

[0035] Specifically, refer to Figure 1-4 A positioning shaft 45 is also provided at the other end of the plurality of supporting arms 43. The clamping plate 44 is provided in an annular plate shape and is made of rubber material.

[0036] In this embodiment, in actual use, the clamping plate 44 can be used to surround and clamp the positioning column 52, thereby achieving the clamping and installation of the filter component 5 on the positioning component 4. In a preferred embodiment, the clamping plate 44 is made of rubber material to provide better clamping force for the positioning column 52, thereby avoiding damage to the positioning column 52 during clamping, and at the same time reducing the overall clamping weight, thereby improving the assembly stability in the ventilator body 2.

A plurality of rotary grooves 47 are opened on the adjusting disk 46, and each positioning shaft 45 corresponds to one of the rotary grooves 47 and slides therein.

[0038] In this embodiment, in the actual adjustment movement, the user connects the power supply to the driving motor 49, and the adjustment disk 46 connected to the output end of the driving motor 49 can be rotated. Through the rotary groove 47 provided on the adjusting disk 46, the rotary groove 47 can drive the positioning shaft 45 to slide therein when it rotates, and cooperates with the linear limitation of the positioning disk 41 by the slide groove 42, so that the support arm 43 at the end of the positioning shaft 45 can drive the clamping plate 44 to move linearly; the user drives the clamping plate 44 to extend outward, and then places the positioning column 52 in a number of clamping plates 44, and then the user controls the clamping plate 44 to surround inward again until the positioning column 52 is clamped to achieve the clamping installation of the filter assembly 5.

[0039] Specifically, refer to Figure 1-4 A rotating shaft is also provided on the side of the positioning disk 41 , and a matching toothed disk 48 is rotatably connected to the outside of the rotating shaft, and the matching toothed disk 48 is meshed with the adjusting disk 46 .

At this time, the rotation groove 47 provided on the adjustment disk 46 can drive the positioning shaft 45 to slide therein when the rotation groove 47 rotates. At this time, the linear limit of the positioning disk 41 by the slide groove 42 is cooperated so that the support arm 43 at the end of the positioning shaft 45 can drive the clamping plate 44 to move linearly; the user drives the clamping plate 44 to extend outward, and then places the positioning column 52 in a plurality of the clamping plates 44, and then the user controls the clamping plates 44 to surround inward again until the positioning column 52 is clamped;

[0044] Step 3: After the positioning column 52 is clamped by a plurality of clamping plates 44, the filter assembly 5 set at this time can be assembled on the positioning assembly 4. When the exhaust gas in the ventilator body 2 passes through the filter assembly 5, the exhaust gas can be filtered and processed by the bottom filter 53 and the activated carbon particle layer 55, and the exhaust gas can be discharged through the bottom filter 53.
