The noise reduction dust collector comprises a shell, a draught fan and a noise reduction frame, the noise reduction frame is installed in the shell, a fixing groove is formed in the noise reduction frame, and the draught fan is installed in the fixing groove; a plurality of noise reduction holes parallel to the draught fan are tightly distributed in the noise reduction frame, a sealing ring extends from the outer wall of the noise reduction frame, and the sealing ring abuts against the inner wall of the shell so that a sealing cavity can be formed between the noise reduction frame and the inner wall of the shell; therefore, the technical problems that the sucked air flow generates strong vibration in an internal channel of the dust collector, and meanwhile, the air flow sucked by the rotation of the high-speed electric fan also generates strong vibration, so that large noise is generated, the use experience is seriously influenced, and inconvenience is brought to a user are solved. 本申请公开了一种降噪吸尘器，包括壳体、风机与消音架，
