Abstract: A garbage-can-type dust collecto includes a housing assembly, an inner barrel body for mounting or fixing a garbage bag, and a draught fan for driving airflow movement such that dust enters the garbage bag. The inner barrel body is detachably mounted on the housing assembly, the inner barrel body is provided with an accommodating chamber, and the garbage bag arranged in the accommodating chamber divides the accommodating chamber into an upper chamber and a lower chamber. The gas extraction hole is communicated to the wind chamber and the upper chamber, the inner barrel body is provided with a gas suction port for extracting air in the lower chamber when the draught fan is in operation, and the gas suction port communicates the wind chamber to the lower chamber. The present disclosure has the beneficial effect of effectively preventing a garbage bag from blowing up.
