[0013] A method for using an oxygen concentrator with a sound absorption and noise reduction mechanism, S1: To realize rapid installation and disassembly of the oxygen machine and facilitate maintenance of the internal parts of the oxygen machine, align the rectangular block with the rectangular bayonet installed on the first soundproof shell, and align it with the rectangular bayonet installed on the second soundproof shell, and slide the rectangular block into the inside of the rectangular bayonet respectively. At this time, the outer side of the rectangular block is tightly attached to the inner side of the rubber shell, the metal pressurized shell is fixed to the first reinforced ear seat through the first buffer soundproofing mechanism, and the metal pressurized shell is fixed to the second reinforced ear seat through the second buffer soundproofing mechanism. The first reinforced ear seat and the second reinforced ear seat are both fixed to the second soundproof shell or the first soundproof shell, and a distance of two millimeters is set between the metal pressurized shell and the first soundproof shell or the second soundproof shell, and then fit the first soundproof shell and the second soundproof shell together, and then fix the connecting column and trapezoidal body card plate at the upper and lower ends of the first soundproof shell and the second soundproof shell respectively, and the trapezoidal body card plate is aligned with the rectangular The first soundproof shell and the second soundproof shell are respectively fitted with the top ends of the first soundproof shell and the second soundproof shell, and the bottom ends of the first soundproof shell and the second soundproof shell are fitted with the top ends of the base plate.

The sound absorbing board can reduce the noise inside the first sound insulation shell and the second sound insulation shell. At the same time, part of the noise will enter the airflow duct from the ventilation and heat dissipation port. The italic sound insulation board can directly absorb the noise, and the arrangement structure between the italic sound insulation boards can greatly reduce the noise.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by setting a rectangular block, a first soundproof shell, a second soundproof shell, a metal pressurized shell and a rectangular bayonet, the rectangular block is aligned with the rectangular bayonet on the first soundproof shell and the second soundproof shell and slides into the inside thereof, so that the oxygen machine can be quickly installed. The close contact between the inner side of the rubber shell and the outer side of the rectangular block provides a buffering effect, reducing noise and collision during the installation process. The structural design of the metal pressurized shell and the rubber shell enhances the overall stability and prevents deformation. At the end of the installation process, the servo motor and the plate cone plate are rotated and squeezed to achieve a stable installation of the oxygen machine. This design simplifies the installation and disassembly steps, facilitates the rapid removal of the fixed frame during later maintenance, and effectively improves the maintenance efficiency. 2. In the present invention, by providing the rubber shell, the metal pressurized shell and the inner air bag, the vibration generated during the operation of the fixed frame is effectively controlled by the synergistic effect of the rectangular block, the rubber shell and the metal pressurized shell. The deformation of the inner air bag and the internal gas flow design, as well as the use of the pull column, enhance the structural strength and provide additional buffering effect, significantly reducing vibration transmission and noise generation, which not only protects the controller and components from damage, but also improves the stability and service life of the entire system; 3. In the present invention, the noise reduction and heat dissipation functions of the oxygen machine are realized through the airflow duct, ventilation and heat dissipation port, the first sound insulation shell and the second sound insulation shell. The inflow of external air not only helps the dissipation of internal heat, but also effectively reduces the internal noise through the sound-absorbing panel. The arrangement structure of the italic sound insulation board further enhances the noise reduction effect, realizes noise control without affecting the heat dissipation performance, and improves the safety of use and equipment performance.
