The upper end of the air pipe 9 communicates with the casing A1.

The shell A1 is a stainless steel shell with high structural strength and is not easy to rust.

The shell B4 is a stainless steel shell with high structural strength and is not easy to rust.

The sound-absorbing layer A6 is filter felt or sound-absorbing cotton sound-absorbing layer, which has good suction effect and long service life.

The sound-absorbing layer B8 is filter felt or sound-absorbing cotton sound-absorbing layer, which has good suction effect and long service life.

The working principle of the utility model: the discharged gas is quickly released into the shell B through the through hole B on the intake pipe, and the gas pressure decreases; the gas in the shell B enters into the shell A through the through hole A, and the gas pressure decreases again , and finally the gas is discharged through the outlet pipe.

The beneficial effects of the utility model are as follows: 1. The structure is simple, easy to repair and maintain, and the noise reduction of the structure is combined with the noise reduction of the material, so that the noise reduction effect of the silencer of the oxygen generator is better and the service life is longer. 2. Shell A is a stainless steel shell with high structural strength and is not easy to rust. 3. Shell B is a stainless steel shell with high structural strength and is not easy to rust. 4. The sound-absorbing layer A is filter felt or sound-absorbing cotton sound-absorbing layer, which has good suction effect and long service life. 5. The sound-absorbing layer B is filter felt or sound-absorbing cotton sound-absorbing layer, which has good suction effect and long service life.
