Abstract
A noise elimination and vibration damping device for an air compressor and an air compressor are provided. An air compressor vent is provided with an inner sleeve therein, a fixed end of the inner sleeve is connected to an inner wall surface of the air compressor vent, a suspended end of the inner sleeve is in a suspended state. A groove is defined on the air compressor vent. A space between the groove and the inner sleeve defines a noise elimination chamber, the noise elimination chamber is provided with multiple noise elimination regions arranged at intervals, and each of the multiple noise elimination regions is filled with magnetic fluid. A first-stage noise elimination structure is disposed on the inner sleeve. The suspended end can generate radial oscillation to drive the magnetic fluid to generate tangential oscillation, thereby attenuating an acoustic energy of a sound entering the noise elimination chamber.
