Abstract

A cyclone dust-collecting apparatus of a vacuum cleaner includes a cyclone body installed at an extension hose for generating air current of vortex from incoming air, a grill for filtering back drafting current of the air current of vortex, and a cyclone cover including a partly blocked plate, which is placed to correspond to the grill, a filth passage for guiding filth to a filth-collecting container, and a first connection member for connecting the cyclone body with the filth-collecting container. The filth-collecting container has second connection member for connecting with the cyclone cover. Accordingly, it can be prevented a grill from being blocked by back drafting of piled filth in the filth-collecting container regardless of the position of a user. When the user eliminates collected filth, breakage of a grill or falling down of the filth clung to the grill, can also be prevented.

Claims

1. A cyclone dust-collecting apparatus of a vacuum cleaner, comprising:

a cyclone body installed at an extension hose for generating air current of vortex from incoming air;

a grill for filtering back drafting current of the air current of vortex; and

a cyclone cover including a partly blocked plate, which is placed to correspond to the grill, a filth passage for guiding filth to a filth-collecting container, and a first connection member for connecting the cyclone body and the filth-collecting container;

wherein the filth-collecting container has second connection member for connecting with the cyclone cover.

2. The cyclone dust-collecting apparatus of claim 1, wherein the first connection member comprises two connection recesses formed on the lower portion of the cyclone cover opposed to each other.

3. The cyclone dust-collecting apparatus of claim 2, wherein the second connection members have two connection protrusions protruding from a upper portion of the filth-collecting container corresponding to the connection recesses of the first connection member.

4. The cyclone dust-vacuum apparatus of claim 3, wherein said second connection member comprises a first connection protrusion supported by being inserted into one of said connection recesses of the cyclone cover, and a second connection protrusion formed on a flexible member and inserted into the other connection groove, and separated from said cyclone cover by adding pressure to said flexible member.
