Further, the vibration assembly further comprises two first vibration O-shaped rings and two second vibration O-shaped rings; the two first vibrating O-shaped rings are respectively and movably connected with the vibrating tube and are respectively positioned outside the vibrating tube; the two second vibration O-shaped rings are movably connected with the vibration tube respectively and are positioned at the tail part of the vibration tube respectively.

In the present embodiment, the first vibration O-ring 33 can axially limit the vibration ring 32 to avoid an excessive amount of movement of the vibration ring 32; the vibration pipe 31 can be flexibly fixed in the air return sleeve 25 through the first air return O-shaped ring 26, the two water pipe O-shaped rings 27 and the two second vibration O-shaped rings 34, and noise generated by high-frequency vibration of the vibration pipe 31 can be reduced.

The working principle and the using process of the invention are as follows: after the air return device is installed, when the air return device works, high-pressure air flows sequentially through the air inlet short pipe 56, the three-hole plug 51, the adapter 21, the adapter 22 and the base 23 to enter the vibration pipe 31, then enters a gap space between the vibration pipe 31 and the vibration ring 32 through the eccentric hole 310 on the vibration pipe 31, forms annular air flow in the gap space, and then sequentially flows through the air return sleeve 25, a gap between the base 23 and the upper handle 11, the adapter 21, the three-hole plug 51 and the air return pipe 57 to discharge air; in the process, the annular air flow formed in the gap space between the vibration tube 31 and the vibration ring 32 blows the vibration ring 32 to rotate at a high speed, and the vibration tube 31 generates high-frequency vibration, and the pneumatic energy is converted into the vibration energy of the vibration tube 31, so that the working tip 42 is driven to vibrate at a high frequency; when adjusting atmospheric pressure, through rotating adjust knob 55, can drive connecting pin 54 with wedge slider 53 rotates the in-process, three hole end caps 51 with between the crossover sub 21 inlet channel 510 cross-sections can be sheltered from and change by wedge slider 53, thereby influence vibrating tube 31 department actual work atmospheric pressure for equipment output changes, and then realizes through rotating adjust knob 55 can adjust work atmospheric pressure and adjusting device output. Through the locking nut 52, the adjusting knob 55 can be axially compressed, and the adjusting knob 55 is prevented from rotating after the working air pressure is adjusted. The first vibration O-ring 33 can axially limit the vibration ring 32, and avoid an excessive movement amount of the vibration ring 32; the vibration tube 31 can be flexibly fixed in the air return sleeve 25 through the first air return O-shaped ring 26, the two water pipe O-shaped rings 27 and the two second vibration O-shaped rings 34, so that the vibration tube 31 can generate high-frequency vibration, and noise generated by the high-frequency vibration of the vibration tube 31 can be reduced. In conclusion, the working air pressure can be adjusted by rotating the adjusting knob 55, the adjusting mode is simple, the operation by a doctor is convenient, the doctor can conveniently diagnose and treat a patient, and the market core competitiveness of corresponding medical equipment can be improved.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
