Description

Vacuum cleaner {vacuum cleaner}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of discharging solids such as dust into a cyclone chamber and having a cyclone built therein.

In a conventional vacuum cleaner, a blower chamber in which a blower is incorporated is disposed in a downstream portion of the main body. A dust collecting chamber in which a cyclone for separating and collecting solid matter such as dust is incorporated is disposed in the upstream portion. And an intake port connected with a desorption material is provided at an upstream end of the main body. And the other end of the hose is provided with a distal end pipe having a grip portion at the time of cleaning. One end of the extension pipe is connected to the distal end pipe by a removable material, and the other end of the extension pipe is connected to a suction pipe Suction ducts are provided as removable materials.

When the conventional vacuum cleaner having such a structure is used for a predetermined period of time, solid matter is accumulated in a dust reservoir provided on the bottom of the cyclone built in the dust collecting chamber, thereby lowering the dust collection efficiency of the cyclone. In this case, the user removes the dust reservoir of the cyclone from the main body, manually floats the accumulated solids in the dust reservoir, and recharges the dust chamber of the main body.

As described above, the cleaning operation of emptying and recharging the dust reservoir causes a problem that the user touches the abomination object by hand and is treated as a very inconvenient and cumbersome operation.

The present invention has a problem in solving the above-mentioned problems.
