Abstract: An handle type cyclone dust-collecting apparatus which is disposed at one side of an extension pipe of a vacuum cleaner. The handle type cyclone dust-collecting apparatus includes a connection body fluidly communicating with the extension pipe and having an air inlet port and an air outlet port, a dust-collecting casing detachably connected with the connection body, and a filter member disposed at the air outlet port to prevent dust particles from being flowing back to the air inlet port with air. The filter member includes a filter body and a conical skirt connected to a lower end of the filter body and having a cut-off part formed in a certain section thereof. A gap between a lower end of the skirt and an inner surface of the dust-collecting casing ranges from 4 mm to 6 mm.

Abstract: The present invention is a cyclone dust collecting apparatus for a vacuum cleaner in which an air-whirling space and a contaminant collecting space are separated from each other. The cyclone dust collecting apparatus for the vacuum cleaner according to the present invention comprises a cyclone body connected to an extension tube; an inner cover provided at a lower side of the cyclone body, the inner cover having a hollow conical shape with an opened upper and lower ends; a grill unit through which the air is discharged, the grill unit being provided at a lower end of an air discharge tube of the cyclone body in the inner cover; and a contaminant receptacle for receiving a contaminant fallen from the inner cover, the contaminant receptacle being provided at a lower side of the inner cover.

Abstract: A dust separating apparatus for a vacuum cleaner having a casing, a cyclone unit formed in the casing to filter contaminants from drawn-in air and discharge air removed of the contaminants, and a dust collection part arranged in parallel with the cyclone unit in the casing to collect the contaminant separated from the air by the cyclone unit. The casing is substantially semicircular to correspond to the mounting chamber of the vacuum cleaner body. On a bottom surface of the cyclone unit, an air inlet and an air outlet are formed. The air outlet is formed at one side of the air inlet.

Abstract: A suction port assembly for a vacuum cleaner, that includes a housing that has a suction port, and a rotary drum rotatably mounted on the housing. The rotary drum has a first bristle member on its outer circumference, which is adapted to contact a surface to be cleaned. An ultrasonic generation unit vibrates the first bristle member.

Abstract: A vacuum cleaner with a sterilizing system including a safety device for a sterilizer thereof. The vacuum cleaner according to an embodiment of the present invention comprises a cleaner body and a suction brush. The suction brush comprises a sterilizer using an ultraviolet (UV) ray; and a safety device interrupting power supply to the sterilizer when the suction brush is moved apart from the surface being cleaned by a predetermined distance. Here, the safety device comprises a micro switch controlling power to the sterilizer, a micro switch operator released from contact with the micro switch as the suction brush is separated from the surface being cleaned by an amount at least equal to the predetermined distance, thereby turning off the micro switch, and a biasing member that biases the micro switch operator in a certain direction.

Abstract: A cyclone dust separating apparatus for separating dust from external air drawn in thereto and discharging the separated dust, comprises at least one first cyclone body having a tubular shape and forming a first cyclone chamber where the external air is rotated; and at least one second cyclone body forming a second cyclone chamber where the air discharged from the first cyclone chamber is rotated again to separate dust, wherein the external air is drawn in through a lower end of the first cyclone chamber and discharged through an upper end of the first cyclone chamber, and the air discharged from the first cyclone chamber is drawn in through an upper end of the second cyclone chamber and discharged through an upper end of the second cyclone chamber.

Abstract: Provided is a multi-cyclone apparatus for a vacuum cleaner with a high dust collection efficiency. The multi-cyclone apparatus has a primary cyclone separating a large-sized contaminant from air drawn in via an air inlet, a guide vane formed under the air inlet in the primary cyclone to increase a speed of air drawn into the primary cyclone, a primary contaminant receptacle collecting a contaminant separated by the primary cyclone, a plurality of secondary cyclones fluidly communicated with the primary cyclone to separate a fine contaminant from drawn-in air, and a secondary contaminant receptacle collecting the contaminant separated by the secondary cyclones.

Abstract: A multi dust-collecting apparatus for a vacuum cleaner separating dirt particles from air by taking two steps. The multi dust-collecting apparatus includes a dust-collecting unit to separate dirt particles from the air by using gravity and inertia, and a plurality of cyclones to swirl the air discharged from the dust-collecting unit and separate the dirt particles from the air by using centrifugal force.

Abstract: A dust receptacle comprising an ultraviolet transmission window and a vacuum cleaner having the same. The dust receptacle includes a receptacle body detachably mounted to a cleaner body, an ultraviolet (UV) transmission window penetratingly formed on the receptacle body, and a Teflon® cover sealing the UV transmission window. The vacuum cleaner having the dust receptacle includes a cleaner body, a dust receptacle detachably mounted to the cleaner body, a UV sterilizer lamp mounted within the cleaner body to scan the dust receptacle with a UV ray, a grill protecting the UV sterilizer lamp. In the vacuum cleaner, the dust receptacle has the same structure as described above.

Abstract: A suction brush and a method for manufacturing the same are provided. The suction brush includes an opening formed toward a surface being cleaned, the UV sterilizer lamp is mounted at an inner space of the opening to project a UV ray onto the surface, and a TEFLON window member covering the inner space. The method includes mounting the UV sterilizer lamp at an inner space of an opening formed toward a surface being cleaned, connecting a TEFLON window member by fitting a plurality of connection projections formed around the opening into a plurality of connection holes formed at the TEFLON window member to correspond to the connection projections, determining a connection position for the TEFLON window member so that the inner space is ventilative, and fixing the TEFLON window member by compressing ends of the plurality of connection projections as penetrating the connection holes by heat and pressure.
