[0028] The working principle of the above embodiment is:

[0029] (1) When the weft knitting machine body 1 generates floating dust when weaving yarn, the fan 402 is started. The fan 402 makes the inside of the annular tube 404 in a negative pressure state through the dust suction pipe 403, so that the generated floating dust is sucked into the inside of the annular tube 404 through the dust suction hole 405, and further transported to the inside of the filter bin 401 through the dust suction pipe 403 and the fan 402. After being filtered by the filter component inside the filter bin 401, the air is blown into the inside of the control box 2 through the air outlet 406 and then discharged through the heat dissipation hole 6, thereby increasing the air circulation inside the control box 2 and improving the heat dissipation effect inside the control box 2.

[0030] (2) After the air containing the floating dust is transported to the filter bin 401 by the fan 402, it will pass downward through the collection box 501 for filtration, and the floating dust will be collected by the collection box 501. When the collection box 501 needs to be cleaned, the positioning plate 510 is moved downward and pressed to disengage it from the positioning groove 506. At this time, the top plate 505 can be slid forward to disengage it from the clamping hole 504 for disassembly, and then the positioning plate 510 is loosened. The spring 509 contracts and drives the limit plate 508 and the top rod 507 to move upward. The top rod 507 pushes the collection box 501 upward, and the collection box 501 can be taken out for processing.
