Abstract

A cyclone separation dust cup, which includes a cup body and a cyclone tube, the cyclone tube being provided with an air inlet, an ash ejection outlet, and an air exhaust outlet; and the ash ejection outlet communicates with a dust storage cavity in the cup body, the air exhaust outlet with an air outlet positioned on the cup body through an air exhaust pipe, and the dust storage cavity with the air exhaust pipe. The dust storage cavity, by communicating with the air exhaust pipe, enables part of the air current entering the cyclone tube to enter the dust storage cavity in the cup body, thus producing suction in the ash ejection outlet of the cyclone tube that can draw the dust into the dust storage cavity. This enables the impurities with a lighter weight (e.g. hair and downy floc), which cannot fall into the dust storage cavity under gravity, to be inhaled into the dust storage cavity successfully, thus greatly improving the separating and filtering effect of this cyclone separation dust cup.
