Suction member and electric vacuum cleaner

By setting a cross-extended protrusion in the main body of the suction unit that contacts the rotating cleaning body, the problem of difficult collection of dust on the end side in the direction of the rotating brush axis is solved, and smooth movement and efficient collection of dust on the end side are achieved.

AI Technical Summary

Technical Problem

In existing suction devices, dust on the axial side of the rotating brush has difficulty reaching the connection port, resulting in residue buildup.

Method used

A protrusion is provided in the main body of the suction unit. The protrusion protrudes from the inner wall of the rotating cleaning body chamber, contacts the cleaning body, and extends in a crisscross manner, ensuring that dust can move smoothly to the connection port as it moves from one end to the center.

Benefits of technology

It effectively collects dust from the end side along the axis of the rotating brush, improving dust collection efficiency and preventing dust from accumulating on the end side.

Abstract

An intake member that easily collects dust on an end side in an axis direction, and an electric cleaner. The intake member is an intake member in an electric cleaner that has a rotating cleaning body having a cleaning body, a drive section that is a drive source for rotating the rotating cleaning body, and an intake member body having a rotating cleaning body chamber (6b) in which the rotating cleaning body is rotatably disposed, the intake member body having: a suction port (6a) disposed on a bottom side; a communication port (6c) located on a center side in an axis direction of the rotating cleaning body and located on a more rear side than an axis (L5) of the rotating cleaning body in a direction orthogonal to the axis direction; and a protruding body (6d) protruding from an inner wall (6j) of the rotating cleaning body chamber (6b) and contacting the cleaning body, the protruding body (6d) extending with an extending direction thereof intersecting the axis direction, and with an end (6d1) on a front side in a front-rear direction existing on a more front side than an end (6d2) on a rear side as the center side is approached from an end side with respect to the axis direction.
