Zusammenfassung:The invention provides an air inflow component of a sewing machine chipping suction device, and belongs to the technical field of sewing machines. The air inflow component of the sewing machine chipping suction device solves the problems that an existing chipping suction device is small in air inflow and poor in chipping suction effect. The air inflow component of the sewing machine chipping suction device is arranged on the cloth chipping suction device of a sewing machine. The cloth chipping suction device of the sewing machine comprises a material suction pipe. The air inflow component of the sewing machine chipping suction device comprises an air inflow support in a circular tube shape, wherein an air inflow channel used to generate negative pressure on the material suction pipe is arranged in the air inflow support. The air inflow component of the sewing machine chipping suction device further comprises an air replenishment piece in a circular tube shape, wherein two ends of the air replenishment piece are respectively communicated with the external world and the air inflow channel. Due to the fact that the air replenishment piece is arranged in the air inflow component of the sewing machine chipping suction device, air inflow of the sewing machine chipping suction device is increased, and chipping suction effects are good. Additionally, a silencer is arranged in the air replenishment piece, and therefore air inflow noise is low, and stable operation of the sewing machine chipping suction device is guaranteed.
