Abstract: A high-speed automatic fire net-based fire instruction control system for a short-range anti-aircraft gun is provided. More particular, the present invention relates to a system, in which when a short-range anti-aircraft gun gunner calibrates values indicated on equipment and follows instructions without personally viewing a flying object that has infiltrated at low altitude, a tracking and automatic fire net is constructed, and the gunner follows fire instructions, thus allowing gunners to easily cope with targets anywhere regardless of the location, such as an anti-aircraft defensive position or a contact area, as long as the targets appear on a detection radar even in unfavorable weather or at night which forbids the targets from being detected and identified with eyes.

Abstract: A cyclone dust collector comprises a cyclone body including a cyclone chamber, a connection path and a dust chamber, wherein the cyclone chamber and the dust chamber are arranged in parallel, a cover unit connected to an upper part of the cyclone body and having a suction path for external air to flow in therethrough, and a backflow prevention member disposed at one sidewall of the dust chamber to prevent collected dust from flowing to the cyclone chamber.

Abstract: A dust collecting apparatus for use in a vacuum cleaner provides improved suction cleaning efficiency. The dust collecting apparatus includes a main body comprising a suction port through which a dust-laden air is drawn, and a first and a second discharge ports through which filtered air is discharged. A filter unit disposed between the suction port and the first discharge port, filters out dusts from the air. A parallel cyclone unit, disposed between the suction port and the second discharge port, removes dusts from the air by centrifugal force. The first discharge port is larger in sectional area than the second discharge port, and therefore, the filter unit has higher dust removal rate than the cyclone unit in the initial stage of the operation. Accordingly, the dust collecting apparatus can provide greater initial suction cleaning efficiency than a dust collecting apparatus having only the cyclone unit.

Abstract: A power cord that includes a plug body supporting an electric wire and including a connecting part, a protecting tube coupled to the plug body, and a movement regulating protrusion formed on the electric wire preventing the protecting tube from separating from the connecting part, wherein a space is formed between an inner surface of the protecting tube and the electric wire.

Abstract: A suction port assembly for a vacuum cleaner and a vacuum cleaner having such a suction port comprises upper and lower housings, a plurality of suction ports formed in the lower housing, and a plurality of suction paths formed in the upper and lower housings to guide the air drawn in through the suction ports. With this arrangement, the efficiency of cleaning the lateral sides of the suction port assembly can be enhanced, and thus a wide area can be efficiently cleaned.

Abstract: A vacuum cleaner suction port assembly has an upper and a lower housings, a first and a second suction ports formed on the lower housing, at least one upper opening pierced in the upper housing, allowing an external air to be drawn therethrough by the suction force of the first and the second suction ports, and at least one lower opening formed on the lower housing, the lower opening located between the first and the second suction ports and fluidly communicating with the upper opening such that the air drawn through the upper opening is guided to between the first and the second suction ports to scatter the dusts therefrom. Accordingly, cleaning efficiency increases not only at both sides, but also at the center of the suction port assembly.

Abstract: A cyclone dust-collecting apparatus comprises an upper casing having an air suction port formed thereon, a lower casing connected to the upper casing to form a cyclone chamber, a guide unit disposed between the upper and the lower casing, and having a first channel for swirling a dirt-laden air drawn in through the air suction port, and a second channel for discharging a cleaned air therethrough; and a filter assembly mounted between the guide unit and the lower casing, for removing a dirt and a dust from the air as drawn in. Accordingly, a compact-sized cyclone dust-collecting apparatus is realized and maintenance management of the vacuum cleaner becomes easy.

Abstract: A suction brush assembly, which is connected with a body of a vacuum cleaner via an air passage, draws in air and dust from a surface to be cleaned. A bendable suction brush is provided that includes a brush body connected with the air passage, and a plurality of movable frames each with a suction passage to draw in the air and dust. The frames are formed on the brush body in a movable manner so as to rotate via an external force to a predetermined angle with respect to the brush body. At least one front frame overlaps portions of the plurality of movable frames to cover an open end of the brush body.

Abstract: Disclosed is a bendable nozzle improved in construction in such a manner that the nozzle body is folded when cleaning out an angled corner area, whereby a convenience in use is enhanced and a wide area is easily cleaned out. The bendable nozzle for a vacuum cleaner includes a nozzle body which is folded and comes into close contact with a wall when it contacts with an angled corner area of the wall. The bendable nozzle includes upper and lower cases provided with a plurality of suction flow passages within the interior thereof. Auxiliary nozzles are hinged to the opposite sides of the upper and lower cases. A corner nozzle moves forward and backward in cooperation with the pivotal movement of the auxiliary nozzles.

Abstract: Disclosed is an inlet unit of a vacuum cleaner. The inlet unit comprises an inlet body having a dust inlet port and removably coupled to an inlet pipe of the vacuum cleaner; and an auxiliary inlet body coupled extendably and contractibly to the inlet body so as to variably cope with a corner having a desired angle, and having an auxiliary inlet port communicated with the dust inlet port in an extending and contracting direction. Therefore, an suction area of the inlet unit can be properly increased or decreased so as to rapidly and simply perform a corner of a room. Further, the sucked foreign substance is not held or fixed with the inlet portion.
