Oxygen generator with long service life

The utility model discloses an oxygen generator with long service life, which comprises a machine body, an outer cover is arranged outside the machine body, a pressing plate is arranged at the top of the outer cover, and a radiator is arranged at the top of the pressing plate. The supporting plate supports the machine body, when relative shaking occurs outside, due to the fact that the top ends of the vertical rods on the two sides are fixedly connected with the bottom end of the supporting plate, and the top end of the middle vertical rod does not make contact with the lower surface of the supporting plate, shaking forces the vertical rods at the two ends to retract into the three-way pipe, and hydraulic oil pushes the middle vertical rod upwards through the middle pipeline; the top end of the middle vertical rod abuts against the lower surface of the supporting plate, impact force borne by the supporting plate is absorbed and converted through negative feedback adjustment, the vibration and shaking frequenc
