A cyclone dust collecting apparatus includes a cyclone body mounted on a telescopic extension pipe of a vacuum cleaner, a cyclone cover and a dust receptacle. The cyclone cover has a cylindrical cover body, one end of which is closed, and a first contaminants path communicating with a first through hole. The dust receptacle is removably coupled to the cyclone cover and has a cylindrical collecting body and a second contaminants path, which communicates with the first contaminants path. The cyclone dust collecting apparatus has a consistently high dust collecting efficiency, regardless of the cleaning position of the vacuum cleaner, and prevents damage to a grill and contamination of the environment.

1. A cyclone dust collecting apparatus for a vacuum cleaner having a telescopic extension pipe, the cyclone dust collecting apparatus comprising: a cyclone body mounted on the telescopic extension pipe of the vacuum cleaner for inducing air and contaminants into a vortex; a cyclone cover coupled to the cyclone body for separating contaminants from the air by centrifugal force, a cyclone cover including a cylindrical cover body and a first contaminants path, the cylindrical cover body having an open end and a closed end and a first through hole formed in a wall of the cover body proximate the closed end, the first contaminants path communicating with the first through hole; and a dust receptacle in communication with the first through hole, the dust receptacle including a cylindrical collecting body having an open end and a closed end, and a second contaminants path formed on an outer wall of the open end, the second contaminants path corresponding to the first contaminants path. 2. The cyclone dust collecting apparatus as claimed in claim 1, wherein the first contaminants path has a length longer than a length of the first through hole formed in the wall of the cover body. 3. The cyclone dust collecting apparatus as claimed in claim 1, wherein the dust receptacle has a recess formed in the closed end of the dust receptacle. 4. The cyclone dust collecting apparatus as claimed in claim 1 further comprising a supporting unit mounted to the telescopic extension pipe. 5. The cyclone dust collecting apparatus as claimed in claim 4, wherein the supporting unit comprises: a fixing member mounted on the telescopic extension pipe; and a protrusion section extending from an end of the fixing member, the protrusion section being received by the recess of the dust receptacle to secure the dust receptacle to the telescopic extension pipe. 6. A vacuum cleaner comprising: a cleaner body; a suction brush coupled to the cleaner body via a telescopic extension pipe and a flexible hose; and a cyclone dust collecting apparatus mounted to the telescopic extension pipe including: a cyclone body for inducing air and contaminants into a vortex; a cyclone cover coupled to the cyclone body, the cyclone cover including a cylindrical cover body and a first contaminants path, the cover body having an open end and a closed end and a first through holed formed in a wall of the cover body proximate the closed end, the first contaminants path communicating with the first through hole; and a dust receptacle removably coupled to the cyclone cover, the dust receptacle including a cylindrical collecting body having an open end and a closed end, and a second contaminants path in communication with the first contaminants path. 7. The vacuum cleaner as claimed in claim 6, wherein the first contaminants path has a length longer than a length of the first through hole formed in the wall of the cover body. 8. The vacuum cleaner as claimed in claim 6, wherein the cyclone dust collecting apparatus further includes a supporting unit mounted to the telescopic extension pipe, the supporting unit supporting the dust receptacle in connection with the cyclone cover. 9. The vacuum cleaner as claimed in claim 8, wherein a recess is formed in the closed end of the dust receptacle, and wherein the supporting unit includes a pin and a spring, the spring biasing the pin into engagement with the recess to support the dust receptacle and secure the dust receptacle to the cyclone cover.
