[0045] The air outlet is a circular air outlet. The circular air outlet is arranged at intervals on the inner side of the annular mounting opening. A secondary limiting groove is arranged at the circular air outlet. The secondary filter cartridge 310 is inserted into the housing 100 through the circular air outlet. The secondary base 320 can be limitedly clamped in the secondary limiting groove.

[0046] In one embodiment of the present invention, the secondary base 320 is provided with an exhaust extension hole communicating with the room. The exhaust extension hole is communicated with the exhaust side of the secondary filter cartridge 310. The secondary base 320 is at least partially located outside the bottom of the housing 100.

[0047] In one embodiment of the utility model, a primary sealing groove and a secondary sealing groove are provided at the top of the housing 100. The top of the primary filter cartridge 210 can be sealed and clamped in the primary sealing groove, so that the air inlet 110 and the exhaust side of the primary filter cartridge 210 are isolated from the top of the inner cavity of the housing 100. The top of the secondary filter cartridge 310 can be sealed and clamped in the secondary sealing groove, so that the exhaust side of the primary filter cartridge 210 and the exhaust side of the secondary filter cartridge 310 are isolated from each other from the top of the inner cavity of the housing 100.

[0048] Specifically, if Figures 1 to 3 As shown, the housing 100 is a cylindrical housing 100.

Furthermore, the air with dust inside the ceiling of the duct machine can be completely filtered by the coarse filter 230 and the fine filter 330 and then discharged from the exhaust extension hole.

[0049] In addition, the primary base 220 and the secondary base 320 are at least partially located outside the housing 100, thereby facilitating the removal of the coarse filter and the fine filter.

[0050] In one embodiment of the present invention, the power device 400 includes a fan. The fan is installed in the exhaust extension hole, and there is a gap between the fan and the outer end surface of the secondary base 320.

[0051] In another embodiment of the utility model, the housing 100 is located inside the ceiling of the duct machine, and the air suction port 110 is arranged flush with the inner surface of the ceiling of the duct machine, thereby improving the dust collection effect.

[0052] Further, in one embodiment of the present invention, the distance between the outer end surface of the primary base 220 and the bottom of the housing 100 is smaller than the distance between the outer end surface of the secondary base 320 and the bottom of the housing 100. The secondary base 320 is arranged in close contact with the maintenance plate in the ceiling of the duct machine, so that the exhaust side of the primary filter cartridge 210 and the exhaust side of the secondary filter cartridge 310 are isolated by the bottom of the inner cavity of the housing 100. The exhaust extension hole is connected to the ventilation hole on the maintenance plate.

[0053] That is to say, the dust removal device inside the ceiling of the duct machine is installed as a whole inside the ceiling of the duct machine and is arranged on the upper side of the maintenance plate. The secondary base 320 is arranged in a fit with the maintenance plate in the ceiling of the duct machine so that the exhaust side of the primary filter cartridge 210 and the exhaust side of the secondary filter cartridge 310 are isolated by the bottom of the inner cavity of the shell 100. The fan is installed in the exhaust extension hole, and there is a gap between the fan and the outer end surface of the secondary base 320 to prevent interference between the fan and the maintenance plate. The exhaust extension hole is connected to the ventilation hole on the maintenance plate so that clean air can be discharged into the room through the ventilation hole on the maintenance plate. By installing the duct machine housing 100 as a whole on the upper side of the maintenance plate, the disassembly and maintenance of the whole machine can be facilitated.
