Abstract

The invention provides an electric dust collector that has excellent antistatic performance. The electric dust collector has a suction member (7), an extension pipe (5) which is connected with the suction member (7) and is made of conductive material, an operation pipe (4) which is connected with the extension pipe (5) and a soft pipe portion (3), and further has a power supply mechanism which supplies power to the suction member (7) from a vacuum cleaner main body (2). The extension pipe (5) has an insulating resin part and a conductive part of the power supply mechanism, which is insulated from the extension pipe (5) and is configured on the insulating resin part. The insulating resin part is covered within a range less than a whole circle of an outer periphery of an end portion in the length direction of the extension pipe (5). The insulating resin part which forms the part of the extension pipe (5) is made of a material containing a charged prevention agent, and compared with a part made of a general resin not containing the charged prevention agent, the insulating resin part is smaller has a smaller surface intrinsic resistance value.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, in particular to an electric vacuum cleaner excellent in static electricity removal performance. Background technique [0002] Conventionally, a general electric vacuum cleaner is configured to include a cleaner main body, a hose part connected to the cleaner main body at one end, an operation tube connected at one end to the other end of the hose part, an extension tube connected at one end to the other end of the operation tube, and A suction piece that is detachably attached to the other end of the extension tube. [0003] An electric vacuum cleaner is known in which an extension pipe includes an outer pipe and an inner pipe inserted into the outer pipe from the other end of the outer pipe, and the inner pipe is slidably connected to the outer pipe so as to be adjustable in length. [0004] Also known is an electric vacuum cleaner in which an electric rolling brush is incorporated into a ...
