[0022] Please refer to Figure 4 The outer wall of the air outlet bin 4 is rotatably connected to a driving shaft 10, and the outer wall of the driving shaft 10 is fixedly connected to a turbofan 11. The outer wall of the driving shaft 10 located below the turbofan 11 is fixedly connected to a guide tube 12. The turbofan 11 is driven to rotate by the driving shaft 10 to exhaust air. Compared with traditional fans, the turbofan 11 has the advantage of low noise. The gas is then guided by the guide tube 12 to perform the next step of producing oxygen.

[0023] Please refer to Figure 3 The inner wall of the silencer chamber 3 is provided with a plurality of silencer cottons 8, and the plurality of silencer cottons 8 are distributed in a linear array. The plurality of silencer cottons 8 are provided with holes in a direction staggered with the air flow, so that the air fully collides with the silencer cotton 8, thereby having the advantage of slowing down the gas flow rate.

[0026] The implementation principle of the air intake structure of an oxygen generator in the embodiment of the present application is as follows: first, the silent motor 5 is started to drive the driving shaft 10 to rotate, and the driving shaft 10 drives the turbofan 11 fixed thereto to rotate through the rotation of the driving shaft 10, so that the turbofan 11 rotates, thereby absorbing the outside air, and the gas enters the air inlet bin 1 through the air inlet net 2, and is filtered by the activated carbon filter 6 to ensure the purity of the gas, and the gas flows into the muffler bin 3 through the first vents 7 on both sides of the air inlet bin 1, and the flowing gas is decelerated by the provided muffler cotton 8 to reduce the noise generated by the air flow, and then the outer panel 16, sound insulation cotton 13, sound insulation pad 14 and keel 15 provided inside the muffler bin 3 form a muffler structure, and the noise generated by the collision of the air and the muffler cotton 8 is further reduced, so that the guide tube 12 discharges the air to the next oxygen production step.
