Abstract

The invention provides an electric dust collector. The subject of the invention is to obtain a light-weighted extension tube and to improve the insulation, and to provide a vacuum cleaner with an extension tube having excellent electrostatic discharging capability. The solution is a vacuum cleaner (1) having a tubular extension tube (5) forming as a portion of an air channel between sucking means and an electric blower (2b), in which the extension tube (5) is composed of resin containing carbon fibers, and the vacuum cleaner comprises an insulation resin member covering a part of the overall outer periphery of the end of the extension tube (5) in the longitudinal direction; and, a conductive member on the insulation resin component and configured as insulated from the extension tube (5).

Description

[0001] The present invention is a divisional application of the invention patent application whose Chinese invention patent application number is 201210018230.1 and the invention name is "electric vacuum cleaner". technical field [0002] The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner capable of improving the weight reduction and insulation of an extension pipe. Background technique [0003] For a long time, the structure of a general electric vacuum cleaner has: a main body of the vacuum cleaner; a hose part connected to the main body of the vacuum cleaner at one end; an operation pipe connected to the other end of the hose part; extension tube; and a suction piece removably mounted on the other end of the extension tube. [0004] An extension tube is known that includes an outer tube and an inner tube inserted into the outer tube from the other end of the outer tube, and is configured as an extension tube in...
