Noise reduction structure of sewing machine dust collection device

The utility model provides a noise reduction structure of a sewing machine dust collection device, and belongs to the technical field of machinery. The noise reduction structure solves the problem that an existing sewing machine dust collection device is high in noise and poor in noise reduction effect. According to the noise reduction structure of the sewing machine dust collection device, the sewing machine dust collection device comprises a cloth bag connector, wherein air inlets are formed in the side of the cloth bag connector, air inlet connecting pipes are connected to the portions, with the air inlets, of the outer side of the cloth bag connector, and the noise reduction structure is arranged in the cloth bag connector. The noise reduction structure comprises a noise reduction plate and noise reduction pipes, wherein the noise reduction plate is arranged in the cloth bag connector, the noise reduction pipes are arranged in the air inlet connecting pipes and communicated with an inner cavity of the cloth bag connector, a plurality of noise reduction holes are formed in the noise reduction plate and the sides of the noise reduction pipes, the space between the noise reduction plate and the inner wall of the cloth bag connector and the space between the noise reduction pipes and the inner walls of the air inlet connecting pipes are filled with noise reduction sponges, and the air inlets are formed between the noise reduction holes formed in the noise reduction pipes and the noise reduction holes formed in the noise reduction plate. The noise reduction structure of the sewing machine dust collection device has the advantages that the noise reduction effect is good, and noise can be effectively lowered.
