During air intake of the air inlet pipe 82, negative pressure is generated near the air inlet, and the arrangement of the collecting cover 86 is beneficial to enabling liquid to be collected in the collecting cover 86 and enter the cylinder 81 along with the air intake. The intake pipe 82 in this embodiment may be connected to a compressor, and the intake amount of the gas may be adjusted by adjusting the compressor.
Further, in this embodiment, at least one abrupt cross section 88 is disposed on the cylinder 81 around the fixing block 83, and the inner diameters of the cylinders 81 on two sides of the abrupt cross section 88 are different.
The fixed block 83 can vibrate by adjusting the flow of the cylinder 81 through adjusting the air inflow, but because the change of the flow is continuous and gradual, the vibration of the fixed block 83 is relatively stable, and in order to make the vibration of the fixed block 83 more violent, the cylinder 81 is internally provided with the sudden change section 88, so that the inner diameter of the cylinder 81 is suddenly, regularly or irregularly increased or reduced, the flow velocity of the fluid is suddenly changed, the lifting force of the vibration block is suddenly changed, and the rising or falling speed of the vibration block is changed. It is preferable that the inner diameter of the cylindrical body 81 is alternately increased and decreased.

Further, the fixing block 83 in this embodiment has a gradually increasing cross section in a direction away from the air inlet pipe 82.
The section of the fixed block 83 is gradually increased, and the section can be matched with the abrupt change section 88, so that the fixed block 83 can continuously vibrate when the gas flow is kept stable in a range. Compared with the method for adjusting the gas flow, the method saves energy consumption, and is favorable for prolonging the service life of the air compressor due to the relatively stable power of the air compressor for adjusting the gas flow.
Further, the fixing block 83 in this embodiment is provided with an elastic member 87 at a side away from the air inlet pipe 82.
The elastic member 87 may be made of rubber or a spring, but may be made of other materials having an elastic pad. Because the intake pipe 82 just begins when admitting air, gas flow control probably has the error, lead to gas flow too big or undersize, when gas flow is too big, can give a very big ascending lifting force of fixed block 83, make fixed block 83 move up fast, probably bump with fixed knot structure or locating part of the upper end of slide bar 85, long-time, many times, the striking of energetical probably can make fixed block 83 or connection structure or fiber take place to damage, shorten the life-span of equipment, so set up elastic component 87, reduce the probability that equipment damaged.
In addition, elastic component 87 can the energy storage, and under normal conditions, the power that fixed block 83 moved downwards can not be greater than gravity, but has increased elastic component 87, and elastic component 87 energy storage may release when fixed block 83 descends, gives the fixed one decurrent thrust for the decurrent speed of fixed block 83 also accelerates, improves the striking speed of fixed block 83 and gas, is favorable to gaseous dispersion.
In this embodiment, each group of swirl vanes 84 may be correspondingly provided with a fixing ring, and each swirl vane 84 is fixed with the corresponding fixing ring, so as to improve the stability of the device.
