Patent Images
1. A vacuum cleaner, comprising:
- a main body;
a dust collection device selectively mounted on the main body;
a dust separation device selectively coupled to the dust collection device by operation of a lever assembly, wherein the lever assembly comprises a lever body mounted on one of the dust collection device and the main body, and a lever handle that extends from the lever body;
compression member configured to be movable by operation of the lever assembly;
a first gear mounted on the lever body; and
a second gear mounted on the dust collection device and disposed adjacent to the first gear, wherein the first gear includes a first circumferential portion having gear teeth configured to interlock with the second gear and a second circumferential portion having a surface without gear teeth thereon.

12. A vacuum cleaner, comprising:
-
a main body; a dust collection device selectively mounted on the main body; a dust separation device selectively coupled to the dust collection device by operation of a lever assembly, wherein the lever assembly comprises a lever body having a first gear and a lever handle that extends from the lever body; a second gear configured to be selectively interlocked with the first gear;
ana compression member configured to be movable by operation of the lever assembly to selectively compress dust within the dust collection body, wherein when the lever handle is rotated from a first position to a second position, the dust collection device moves upward and is coupled to the dust separation device in a state in which the compression member does not compress the dust, and when the lever handle is rotated from the second position to a third position, gear teeth of the first gear engage with gear teeth of the second gear to rotate the compression member.
