Abstract

The invention provides a suction structure and a suction method for an air suction device of a sewing machine. The air suction device comprises a dustbin storing waste materials. The top cover of the dustbin is provided with an air inlet and a suction outlet. The exhaust inlet is communicated with an air suction motor. The dustbin is internally provided with a spiral air suction channel communicated with the suction outlet. The spiral air suction channel is used to make spiral airflow form in the dustbin under the suction forces of the air suction motor, so as to form a strong negative pressure region, and make the air inlet of the dustbin have very strong suction forces. Under the condition that the power of the air suction motor is not changed, the strongest air suction effect is achieved.

Description

technical field [0001] The invention relates to an air suction device for a sewing machine, in particular to an air suction structure and an air suction method of the air suction device for a sewing machine. Background technique [0002] The suction device is one of the most important additional devices in the sewing machine, which is mainly used to collect impurities such as thread ends and rags. At present, the air suction device is divided into two categories, one is a pneumatic air suction device coordinated with an external air source, and the other is an electric air suction device driven by a motor. The existing air suction device sucks air in a vertical way, the suction is small, the air displacement is small, and the suction efficiency is low. If you want to increase the suction and air displacement, you must increase the motor power, which will bring the motor cost and power consumption. amount increased.
