In the process, the inwards concave dust collecting groove is arranged in the exhaust pipe, so that most of the sundries with small volume in the exhaust pipe can be accumulated in the dust collecting groove, and only the sundries with large volume and a small part of the sundries with small volume enter the collecting bag for collecting the sundries through the pipeline in the air pipe generating device. Therefore, the dust collector can collect most dust in the dust collecting groove of the exhaust pipe, so that the load and the sundry accumulation degree of the collecting bag are greatly reduced, and the cleaning requirement of the collecting bag is further reduced. Meanwhile, the exhaust pipe can be made of various plastics or other materials easy to clean as required, the exhaust pipe only needs to be detached and cleaned during cleaning, the cleaning difficulty is low, and residues cannot be accumulated to influence the cleaning effect; or when the exhaust tube and the filter bag are cleaned, the inlet end of the exhaust tube can be put into clean water, then the dust collector is started, and the dust collector can suck the clean water and also spirally introduce the clean water into the exhaust tube, so that the exhaust tube and the collection bag are very conveniently cleaned; or the collecting bag can be plugged into the outlet end of the wind energy pipe, the outlet port of the wind energy pipe is covered, then the blowing mechanism is started, and air flow blown by the blowing mechanism reversely enters the material pipe and the air exhaust pipe through the wind energy pipe, so that self-cleaning is realized.

In addition, the dust collector has simple structure, can meet the suction requirements of various solids or liquids, has extremely wide application range, low manufacturing cost, stable work and long service life.

The axis of the wind energy pipe 21 coincides with the axis of the material pipe 22, so that an inner cavity between the wind energy pipe and the material pipe is in a central symmetry annular shape, internal airflow is more uniform, and more effective cyclone and air extraction effects are further formed.

In the dust collector, the wind energy ring 24 and the closed ring 25 can be used as parts and installed between the wind energy pipe 21 and the material pipe 22, and can also extend out from the inner wall of the wind energy pipe 21 or the outer wall of the material pipe 22 to the material pipe or the wind energy pipe; wherein, the wind energy ring 24 is horn-shaped, and the inlet end of the horn is connected with the outlet end of the material pipe 22, while the outlet end is connected with the inner wall of the wind energy pipe 21, thereby improving the cyclone production effect; in addition, all the wind hole groups on the wind energy ring are uniformly arranged on the wind energy ring 24 along the circumferential direction, and the axis of each wind hole 26 can be arranged to be parallel to the axis of the wind energy pipe 21, can also be arranged to be positioned on the same plane with the axis of the wind energy pipe, and the opening direction points to the inner wall of the wind energy pipe or the axis of the wind energy pipe, and can also be arranged to be positioned on a different plane with the axis of the wind energy pipe 21; in addition, the sealing ring 25 may be disposed at the middle section between the inlet end of the wind energy pipe 21 and the air inlet cylinder 23, as shown in fig. 2, or at the inner end of the air inlet cylinder 23, as shown in fig. 4, so as to prevent the airflow from flowing to the cavity between the inlet end of the wind energy pipe and the air inlet cylinder, thereby reducing turbulence and improving airflow utilization rate, and in addition, the sealing ring 25 may be a flat ring shape, or a horn shape with a straight line or an arc-shaped bus, as shown in fig. 5; furthermore, the axial direction of the air inlet cylinder 23 can be either perpendicular to the axis of the wind energy pipe 21 or obliquely directed towards the outlet end of the material pipe 22, as shown in fig. 6. Through the arrangement of the wind energy rings, the closed rings and the air inlet cylinder with different shapes and structures, different cyclone effects can be formed, so that different use requirements are met.
