BACKGROUND OF THE INVENTION

Industrial Availability

The present invention relates to a structure of a dust presser which is employed in a separator using a cyclone.

In a conventional dust housing employing a cyclone, dust is randomly settled inside the dust housing by a dust separator, and thus causes inconvenience when a user uses the dust housing by scattering over a wide area. The present invention provides a structure for compressing dust which has settled in the dust housing, thus making it possible for a user to empty the dust housing more conveniently.

A compression plate capable of compressing dust is disposed vertically in the center of the dust housing. The compression plate is connected to a gear structure having a predetermined gear ratio with a compression lever, and is automatically operated using a motor. The rotation of the compression plate enables dust in the dust housing to be compressed. The compression plate continues to rotate while a cleaner operates, so that it is possible to visually check the effect of dust compression. In this situation, a compression cover is disposed above the dust housing, so as to prevent dust from being re-scattered and to easily compress dust. The compression lever is able to be continuously operated when dust is drawn in using the suction force from the motor, which is capable of rotating forward or in reverse.
