Abstract
Abstract A cyclone dust collecting assembly for a vacuum cleaner includes a dust barrel that is detachable from a cyclone body. The cyclone dust collecting assembly includes a cyclone body disposed in a dust chamber of a cleaner body, for separating by centrifugal force a contaminants from air that is drawn through a suction brush, a dust barrel removably connected to a lower end of the cyclone body. The dust barrel communicates with the cyclone body and collects the contaminants. The apparatus further includes a connecting/separating portion for removably connecting the dust barrel in the dust chamber to the lower end of the cyclone body.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
103 words
A cyclone dust collecting assembly for a vacuum cleaner, comprising: a cyclone body disposed in a dust chamber of a cleaner body, for separating by centrifugal force a contaminant from air that is drawn through a suction brush; a dust barrel removably connected to a lower end of the cyclone body, for collecting the contaminant separated by centrifugal force; and connecting/separating means having a movable unit for removably connecting the dust barrel in the dust chamber to the lower end of the cyclone body by raising/lowering the dust barrel, wherein the movable unit reciprocates along a slanted recess formed in the dust barrel.
Claim 2
Dependent Claim
103 words
A cyclone dust collecting assembly for a vacuum cleaner, comprising: a cyclone body disposed in a dust chamber of a cleaner body, for separating by centrifugal force a contaminant from air that is drawn through a suction brush; a dust barrel removably connected to a lower end of the cyclone body, for collecting the contaminant separated by centrifugal force; and connecting/separating means having a movable unit for removably connecting the dust barrel in the dust chamber to the lower end of the cyclone body by raising/lowering the dust barrel, wherein the movable unit reciprocates along a slanted recess formed in the dust barrel.
Claim 3
Dependent Claim
54 words
The cyclone dust collecting assembly of claim 1 , wherein the slant recess is formed in a lower end of the dust barrel, and the connecting/separating means comprises a base for movably supporting movable unit from a lower portion of the dust chamber such that the movable unit is reciprocated along the slanted recess.
Claim 4
Dependent Claim
40 words
The cyclone dust collecting assembly of claim 2 , wherein the slanted recess spirals outward from a center to an outer edge of the dust barrel, the slanted recess gradually increasing in depth as it extends toward the outer edge.
Claim 5
Dependent Claim
80 words
The cyclone dust collecting assembly of claim 2 , wherein the movable unit comprises: a movable lever disposed between the base and the dust barrel, the movable lever having a protrusion, the protrusion being received in and guided along the slant recess; a pin formed on one end of the movable lever, for rotatably supporting the movable lever on the base; and a handle formed on the other end of the movable lever and extending outside of the dust chamber.
Claim 6
Dependent Claim
25 words
The cyclone dust collecting assembly of claim 4 , wherein the movable lever, the rotary pin, and the handle are integrally formed with each other.
Claim 7
Dependent Claim
28 words
The cyclone dust collecting assembly of claim 4 , wherein the protrusion is formed on the movable lever and offset from a middle line of the movable lever.
Claim 8
Dependent Claim
19 words
The cyclone dust collecting assembly of claim 2 , wherein the base is integrally formed in the cleaner body.
Claim 9
Dependent Claim
22 words
The cyclone dust collecting assembly of claim 1 , wherein the dust barrel has a handle formed on an outer wall thereof.
Claim 10
Dependent Claim
111 words
A cyclone dust collecting assembly for a vacuum cleaner having a suction brush and a dust chamber, the cyclone dust collecting assembly comprising: a cyclone body disposed in the dust chamber, the cyclone body separating contaminants from air that is drawn in through the suction brush; a dust barrel removably connected to a lower end of the cyclone body, the dust barrel collecting the contaminants, the dust barrel including a bottom plate having a recess formed therein; and a movable unit for raising and lowering the dust barrel into contact with the cyclone body, the movable unit including a protrusion, the protrusion being received in the recess of the bottom plate.
Claim 11
Dependent Claim
111 words
A cyclone dust collecting assembly for a vacuum cleaner having a suction brush and a dust chamber, the cyclone dust collecting assembly comprising: a cyclone body disposed in the dust chamber, the cyclone body separating contaminants from air that is drawn in through the suction brush; a dust barrel removably connected to a lower end of the cyclone body, the dust barrel collecting the contaminants, the dust barrel including a bottom plate having a recess formed therein; and a movable unit for raising and lowering the dust barrel into contact with the cyclone body, the movable unit including a protrusion, the protrusion being received in the recess of the bottom plate.
Claim 12
Dependent Claim
34 words
The cyclone dust collecting assembly of claim 9 , wherein the recess spirals outward and gradually increases in depth from a center of the bottom plate to an outer circumference of the dust barrel.
Claim 13
Dependent Claim
58 words
The cyclone dust collecting assembly of claim 9 , wherein the movable unit includes a lever having a first and a second end, a pin located proximate the first end, and a handle located at the second end, and further comprising a base pivotally supporting the movable unit, the base having a supporting hole for receiving the pin.
Claim 14
Dependent Claim
24 words
The cyclone dust collecting assembly of claim 11 , wherein the lever, the pin and the handle of the movable unit are integrally formed.
Claim 15
Dependent Claim
