Abstract

The cyclone dust collecting device has a grill assembly (400) at an air outflow port of the cyclone body (20) for preventing reverse flow of dust and dirt into the air outflow port. The grill assembly comprises a first grill member (410) with a supporter supported on the air outflow port. A second grill member (420) has a grill portion comprising fine passage holes to provide fluid communication to the air outflow port. A connection member (430) facilitates for separable connection of the first and second grill members.

Description

technical field [0001] The present invention mainly relates to a vacuum cleaner, in particular to a cyclone-type dust collecting device for a vacuum cleaner. The device generates an air vortex in the dust-laden air sucked into the cyclone-type dust-collecting device and uses the centrifugal force of the air vortex to separate the dust-laden dust. Dust and pollutants in the air. Background technique [0002] Figure 1-3 A conventional cyclone dust collection device for a vacuum cleaner is schematically shown as disclosed in US Patent No. 6,195,835 (assigned to the same assignee as the present invention). [0003] Refer below figure 1 , The cyclone dust collection device of the traditional vacuum cleaner generally consists of a cyclone separator main body 20 , a dust collection chamber 30 , and a grill assembly 40 . [0004] The cyclone body 20 is divided into an upper body 21 and a lower body 22 fixed by a plurality of screws 23 . The opening of the first connection pipe ...
