摘要：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 exhaustoutlet; 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 airexhaust pipe, and the dust storage cavity with the air exhaust pipe. The dust storagecavity, by communicating with the air exhaust pipe, enables part of the air currententering the cyclone tube to enter the dust storage cavity in the cup body, thusproducing suction in the ash ejection outlet of the cyclone tube that can draw the dustinto the dust storage cavity. This enables the impurities with a lighter weight (e.g. hair anddowny floc), which cannot fall into the dust storage cavity under gravity, to be inhaledinto the dust storage cavity successfully, thus greatly improving the separating andfiltering effect of this cyclone separation dust cup.
