The invention discloses an air pressure adjusting structure which comprises a shell assembly, a machine core assembly, a vibration assembly, a working assembly and an air inlet pressure adjusting assembly. The vibration assembly comprises a vibration pipe and a vibration ring. The air inlet pressure adjusting assembly comprises a three-hole plug, a locking nut, a wedge-shaped sliding block, a connecting pin, an adjusting knob, an air inlet short pipe and an air return pipe. During working, high-pressure airflow enters the clearance space between the vibration pipe and the vibration ring through an eccentric hole in the vibration pipe, the airflow blows the vibration ring to rotate at a high speed, the vibration pipe generates high-frequency vibration, and therefore the working assembly is driven to vibrate at a high frequency. When the air pressure is adjusted, the adjusting knob is rotated to drive the connecting pin and the wedge-shaped sliding block to rotate, in the rotating process of the wedge-shaped sliding block, the section of an air inlet channel between the three-hole plug and the machine core assembly can be blocked by the wedge-shaped sliding block to be changed, and therefore the actual working air pressure at the position of the vibration pipe is affected, the output power of equipment is changed, the adjusting mode is simple, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an air pressure regulating structure. Background technique [0002] In the actual use of pneumatic medical equipment in the dental field, due to the different oral conditions of different patients, and the usage scenarios may be different, it often occurs that the same equipment is given to different patients with the same parameters or used in different scenarios. In the case of a large difference in experience, in order to make all patients have a better experience in different usage scenarios, doctors need to adjust the working air pressure of the equipment in real time, and the current pneumatic medical equipment can only input the working air pressure by adjusting the equipment To change its output power to match different patients or use scenarios, the operation process is very troublesome, and it is impossible for doctors to conveniently adjust the working air pr...
