Electric vacuum cleaner

Abstract

A electric vacuum cleaner, comprises: a joint pipe, the sucking port main body is communicated to the connecting pipe when the sucking port main body is connected to the connecting pipethe sucking port main body; the joint pipe member comprises a first joint pipe rotatably connected to the suction port main body at one end and a second joint pipe rotatably connected to the other end of the first joint pipe at one end; a descending pipe part at the other end of the first joint pipe and an ascending pipe part at the one end of the second joint pipe are rotatably coupled together; and handle shank member.

Description

technical field [0001] The invention relates to an electric duster. Background technique [0002] The suction port used on the existing electric vacuum cleaner is connected to the handle part through the extension pipe, and by making the handle part rotate around the axis of the longitudinal direction of the extension pipe, the It has a curved tubular shape on the connection structure, and can be rotated to a certain extent. These structures are disclosed, for example, in Japanese Patent Laid-Open Publication No. Hei 5-245073. [0003] In addition, in recent years, through the improvement of the suction port, the twist angle of the handle part is related to the rotation angle of the suction port, and an electric vacuum cleaner that can rotate the rotation angle of the suction port up to 180 degrees. Implemented by Hitachi, Ltd. in 1997. [0004] Also, for example, in the "Japanese Patent Laid-Open No. 4-161126" publication of the Japanese Patent Laid-Open Gazette, it is s...

[0008] Also, in the prior art in which the handle portion and the suction hose portion are rotatably provided, since the pipe shaft constituting the curved connection portion of the handle portion and the pipe shaft of the suction hose portion are rotatably directly connected Since it is connected, when the handle part is twisted left and right, the suction hose part will swing to the left and right with the grip part as the center, and as a result, the burden on the wrist will increase.
