[0025] like Figure 2 、 Figure 3 As shown, the protective assembly 3 includes a protective cover 31, and mounting openings 32 are provided on the left and right sides of the protective cover 31. The inner walls of the two mounting openings 32 are movably installed on the surface of the reverse filter disc 4 away from each other. An external interface 36 is provided on the top of the protective cover 31, and the bottom of the protective cover 31 is fixedly installed on the lower surface of the mounting assembly 1. Two mounting brackets 33 are fixedly connected to the upper and lower inner walls of the two mounting openings 32. Motors 34 are fixedly connected to the opposite surfaces of the two mounting brackets 33. Fans 35 are fixedly connected to the output ends of the two motors 34, and the two fans 35 are located on the opposite side of the two reverse filter discs 4. The inner wall of the protective cover 31 is fixedly connected to sound-absorbing foam 38, and the inner cavity of the protective cover 31 is fixedly connected to sound-absorbing cotton 39, and the sound-absorbing cotton 39 is located on the inner side of the sound-absorbing foam 38.
[0026] The mounting openings 32 provided on both the left and right sides of the protective cover 31 serve to assist in the installation of the mounting bracket 33, the motor 34 and the fan 35, providing power to drive the internal airflow to the outside. The reverse filter disc 4 movably installed on the side where the inner walls of the two mounting openings 32 are away from each other serves to filter the entry of external dust and reversely discharge the internally deposited dust. At the same time, the combination of the sound-absorbing foam 38 fixedly connected to the inner wall of the protective cover 31 and the sound-absorbing cotton 39 fixedly connected to the inner cavity of the protective cover 31 serves as a sound-absorbing material to prevent the propagation of sound, thereby reducing the diffusion of sound inside or outside the room and improving the comfort of the medical environment.
[0027] like Figure 2 、 Figure 4 、 Figure 5 As shown, a vibrator 37 is fixedly connected to the top of the inner cavity of the protective cover 31 and the vibrator 37 is located on the right side of the external interface 36. The output end of the vibrator 37 overlaps with the top of the medical compressor body 5. The mounting assembly 1 includes a mounting base 11. The left and right sides of the top of the mounting base 11 are fixedly connected with buffer assemblies 12. The tops of the two buffer assemblies 12 are movably installed on the left and right sides of the bottom of the medical compressor body 5. The two buffer assemblies 12 include two mounting rings 121. The inner walls of the two mounting rings 121 are provided with sliding grooves 122. The inner walls of the two sliding grooves 122 are slidably connected with sliders 123 in the front, back, left and right directions.
[0028] The vibrator 37 fixedly connected to the top of the inner cavity of the protective cover 31 provides power to drive the vibration of the medical compressor body 5, thereby shaking off the dust on its surface. The fan is used to extract the internal dust and discharge it out through the mounting openings 32 on both sides, and then the bottom of the medical compressor body 5 is movably mounted on the inner walls of the two mounting rings 121.

When the vibrator 37 stops, the medical compressor body 5 returns to stability.
[0031] The working principle of the present invention is as follows: the installation openings 32 on both sides of the protective cover 31 serve to assist in the installation of the mounting bracket 33, the motor 34 and the fan 35, provide power to drive the internal airflow to the outside, and the reverse filter disc 4 movably installed on the side where the inner walls of the two mounting openings 32 are away from each other serves to filter the entry of external dust and reversely discharge the dust deposited inside. At the same time, the sound-absorbing foam 38 fixedly connected to the inner wall of the protective cover 31 and the sound-absorbing cotton 39 fixedly connected to the inner cavity of the protective cover 31 act as a sound-absorbing material to prevent the spread of sound, thereby reducing the diffusion of sound inside or outside the room and improving the sound quality. In order to improve the comfort of the medical environment, the vibrator 37 fixedly connected to the top of the inner cavity of the protective cover 31 provides power to drive the vibration of the medical compressor body 5, shake off the dust on its surface, and use the fan to extract the internal dust and discharge it from the installation openings 32 on both sides. Then, the bottom of the medical compressor body 5 and the inner walls of the two mounting rings 121 are movably installed, and the dampers 124 fixedly connected to the bottom of the four sliders 123 and the springs 125 movably sleeved on the outer surfaces of the four dampers 124 are combined to buffer the up and down vibrations of the vibrator 37.
