Patent ID: 11154873

Abstract:
A multi-cyclonic dust filter device comprises a dust collection chamber for collecting dust, a cyclonic chamber providing a gas to-be-filtered out dust to enter and forming a first cyclone to enter into the dust collection chamber, and a deflector component disposed between the dust collection chamber and the cyclonic chamber; the deflector component comprises a first deflector tube for receiving the gas to-be-filtered out dust refluxed from the dust collection chamber and forming a second cyclone, and a second deflector tube disposed in a same axial direction as the first deflector tube and separately disposed by an airflow convergence interval, the first deflector tube is provided with at least one dust filter hole for discharging the dust in the second cyclone, and the second deflector tube combines the first cyclone and the second cyclone through the airflow convergence interval to form a third cyclone for discharging.
