Example 1

[0019] A noise reduction device for a medical oxygen concentrator includes a Y-shaped air inlet pipe 1. The Y-shaped air inlet pipe 1 comprises a straight pipe section 101 and a Y-shaped pipe section 102. Firstly, the Y-shaped air inlet channel of the Y-shaped pipe section 102 increases the area of ​​the air inlet, controls the flow velocity below a critical flow velocity, and reduces air intake noise. Furthermore, the Y-shaped pipe can be made of silicone material to reduce vibration generated during air intake, effectively preventing vibration and reducing noise. One end of the straight pipe section 101 is connected to the second slide tube 1021 of the Y-shaped pipe section 102. The end of the straight pipe section 101 connected to the Y-shaped pipe section 102 is provided with a first slide tube 1011, which slidably fits onto the outside of the second slide tube 1021. A first retaining ring is integrally formed on the outside of the second slide tube 1021, and a second retaining ring is integrally formed on the outside of the straight pipe section 101. A buffer corrugated pipe section 1022 is integrally formed on the first retaining ring, and the other end of the buffer corrugated pipe section 1022 is connected to the second retaining ring on the straight pipe section 101. When the airflow enters and converges along both ends of the Y-shaped pipe section 102, the second slide tube 1021 and the first slide tube 1011 can slide during the impact of the converging airflow, and the buffer corrugated pipe section 1022 can act as a shock absorber, thereby reducing the vibration noise generated by the converging airflow.

[0020] A noise-reducing jacket 1023 is fitted over the outside of the buffer bellows section 1022. The noise-reducing jacket 1023 is made of elastic sound-insulating cotton and is fitted tightly against the outside of the buffer bellows section 1022 to further improve noise reduction performance. Several equally spaced lubricating oil storage ring grooves 1012 are formed on the inner wall of the first slide tube 1011, and the lubricating oil storage ring grooves 1012 are filled with solid lubricating oil, which makes the sliding between the first slide tube 1011 and the second slide tube 1021 smoother and avoids noise generated during sliding.

[0021] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: When the airflow enters and converges along the two ends of the Y-shaped tube 102, the second slide tube 1021 and the first slide tube 1011 can slide during the impact of the airflow convergence, and the buffer corrugated tube 1022 can play a shock absorption and buffering role, thereby reducing the vibration noise generated by the airflow convergence. The inner wall of the first slide tube 1011 is provided with several lubricating oil storage ring grooves 1012 for filling solid lubricating oil, making the sliding between the first slide tube 1011 and the second slide tube 1021 smoother and avoiding noise generated by the sliding. Example 2

[0022] The straight pipe section 101 is mounted on the intake pipe mounting bracket 2. The intake pipe mounting bracket 2 includes a base 201, which is used to mount and fix it in the oxygen generator body. A pipe support sleeve 202 in the shape of a semi-circular ring is integrally formed on the base 201. The pipe support sleeve 202 is provided with an elastic pipe buckle 203 inside, and the elastic pipe buckle 203 is elastically fastened to the outside of the straight pipe section 101. By pressing the straight pipe section 101, the straight pipe section 101 can be fastened to the elastic pipe buckle 203 of the intake pipe mounting bracket 2, thereby quickly completing the installation and fixation of the Y-type intake pipe 1.

[0023] A shock-absorbing gap is left between the inner cavity of the pipe support sleeve 202 and the outer wall of the elastic pipe buckle 203. Several buffer springs 204 are provided between the inner cavity of the pipe support sleeve 202 and the outer wall of the elastic pipe buckle 203. The buffer springs 204 are arranged in a ring array along the axial direction of the pipe support sleeve 202 to further reduce noise during the air guiding process of the Y-type air intake pipe 1.

[0024] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: By pressing the straight pipe section 101, the straight pipe section 101 can be fastened into the elastic tube buckle 203 of the air intake pipe mounting bracket 2, thereby quickly completing the installation and fixation of the Y-shaped air intake pipe 1.
