[0023] like Figure 1 , Figure 2 and Figure 6 As shown, an axial flow fan with a dust removal function comprises an axial flow fan body 1, a connection box 2 is installed on one side of the axial flow fan body 1, and a mounting cylinder 3 is arranged at one end inside the connection box 2, a blocking ring 4 is installed at the other end inside the mounting cylinder 3, and a through hole 5 is opened on the side end surface of the blocking ring 4, the blocking ring 4 is threadedly connected to the mounting cylinder 3, and an air filter element 6 is installed at one end inside the mounting cylinder 3;

[0024] The sealing ring 4 and the mounting cylinder 3 are installed to limit the air filter element 6, and the external air enters the air filter element 6 through the through hole 5. When the axial flow fan body 1 is running, the air filter element 6 can block the dust impurities in the air, thereby achieving the dust removal effect and improving the air quality output by the axial flow fan body 1;

[0025] like Figure 1 and Figure 3 As shown, a groove 7 is provided on one end face of the connection box 2, and a plug rod 8 is installed inside the groove 7, the plug rod 8 is slidably connected to the connection box 2, one end of the plug rod 8 is connected to a rubber head 9, and the rubber head 9 and the plug rod 8 are bonded, and the rubber head 9 and the plug rod 8 are snap-fitted, which is convenient for the installation tube 3 and the connection box 2 to be disassembled;

[0026] When the air filter element 6 needs to be disassembled, the operator can manually pull the insertion rod 8 to disengage the rubber head 9 from the connection box 2, so that the installation cylinder 3 can be taken out, which is convenient for disassembly and assembly;

[0027] like Figure 1 , Figure 4 and Figure 5As shown in the figure, a support partition 10 is provided at the other end inside the installation cylinder 3, and a convex block 12 is installed inside the support partition 10. One end of the convex block 12 is connected to a limit ring 11. The installation cylinder 3 is slidably connected to the limit ring 11, and the installation cylinder 3 communicates with the limit ring 11. A ventilation opening 13 is provided at one end of the limit ring 11. A baffle 14 is provided inside the ventilation opening 13. The baffle 14 is rotatably connected to the limit ring 11, and the side view of the baffle 14 is rectangular;

[0028] The gas filtered by the air filter element 6 in the installation cylinder 3 enters the limit ring 11. The baffle 14 is closed with the limit ring 11 by its own weight. When the axial flow fan main body 1 operates and inhales gas, the impact force of the gas flow can open the baffle 14, so that the dust-removed gas reaches the axial flow fan main body 1. Each air filter element 6 is installed separately. When cleaning and replacement are required after long-term use, the operator can remove the installation cylinder 3 at different time periods. The operator can disassemble the limit ring 11 from the support partition 10, install the limit ring 11 reversely, so that one end of the baffle 14 is on the left.

[0029] In summary, for the axial flow fan with dust removal function, during use, first, when the axial flow fan main body 1 operates, air enters the air filter element 6 through the through hole 5 inside the sealing ring 4. The sealing ring 4 and the installation cylinder 3 are installed to limit the air filter element 6. The air filter element 6 blocks dust and impurities in the air to achieve the dust removal effect. The gas filtered by the air filter element 6 in the installation cylinder 3 enters the limit ring 11. The baffle 14 is closed with the limit ring 11 by its own weight. When the axial flow fan main body 1 operates and inhales gas, the baffle 14 can be opened by the impact force of the gas flow, so that the dust-removed gas reaches the axial flow fan main body 1. When cleaning and replacement are required after long-term use, the operator can remove the installation cylinder 3 at different time periods. The operator disassembles the limit ring 11 from the support partition 10, installs the limit ring 11 reversely, so that one end of the baffle 14 is on the left. When the axial flow fan main body 1 operates, the reversely installed limit ring 11 and the support partition 10 are in a closed state, and air enters the axial flow fan main body 1 from other air filter elements 6. This is the working principle of the axial flow fan with dust removal function.
