Suction head of electric suction cleaner and electric suction cleaner with the same head

Abstract

The invention relates to a suction head of an electric vacuum cleaner, comprising: a dust suction unit having an opening for sucking up dust on the surface to be cleaned; parts; and a dust sweeping part arranged in the dust suction unit for sweeping up dust. The opening, the coupling, and the connecting pipe are all provided with passages for the suctioned dust to pass through, and the coupling can rotate relative to the dust collection unit in a direction roughly parallel to the surface to be cleaned until the long axis of the dust collection unit until the central axis in the longitudinal direction of the connecting pipe is substantially parallel to the central axis in the longitudinal direction of the connecting pipe. Since the coupling piece is connected to the top of the dust collection unit, when the central axis of the long axis direction of the dust suction unit is roughly parallel to the central axis of the long axis direction of the connecting pipe, both the coupling piece and the connecting pipe are located above the dust collection unit.

Description

technical field [0001] The present invention relates to the overall structure of an electric vacuum cleaner, and more specifically relates to the improvement of the usability of the suction head. Background technique [0002] pass below Figure 14 The structure of the conventional suction head 1 is explained. As shown in Japanese Patent Laid-Open Publication No. 2002-102125, by adding a turning force on the left and right directions of the handle 16 during operation, the suction head 1 installed on the front end of the handle 16 can be moved from Figure 14 The state of (a) is rotated to the user who holds the handle 16 for cleaning Figure 14 (b) The vertical state. In this way, the suction head 1 can be extended into a narrow place, and it is also possible to clean a corner or the like. [0003] In addition, a support unit 7 made of rollers or the like is provided on a certain degree of the rear portion of the dust collection unit 4 to keep the dust collection unit 4 para...

AI Technical Summary

Problems solved by technology

[0004] But in above-mentioned existing device, the center of rotation of dust suction unit 4 deviates from the center of dust suction unit 4 relatively big, need to arrange aforementioned support unit 7 in addition dust suction unit 4 rear, therefore, the suction head under the lengthwise state The horizontal width of the suction head 1 will also become larger, and only the front end of the suction head 1 can extend into the narrow gap.
