Nitrogen discharge silencer of small molecular sieve oxygen generator

The utility model discloses a small molecular sieve oxygenerator nitrogen discharge silencer, including nitrogen discharge silencer main part and dustproof main part, the dustproof main part is provided the output end of nitrogen discharge silencer main part, the nitrogen discharge silencer main part includes external support pipe, sound insulation sponge, support ring stand, second exhaust pipe, first exhaust pipe, tail baffle and handle, the outer side of the sound insulation sponge is fixedly connected to the inner side of the external supporting pipe, and the two supporting ring frames are fixedly connected to the inner side of the external supporting pipe. Through the staggered exhaust hole design of the first exhaust pipe and the second exhaust pipe, reflection and scattering of sound waves at multiple angles are achieved, meanwhile, the sound insulation sponge further absorbs the sound waves, noise generated during nitrogen emission is remarkably reduced, automatic opening and closing during nitrogen e
