Turbine brush

Abstract

A turbine brush for a vacuum cleaner comprises a brush body having an upper casing and a lower casing, and the lower casing having a suction slot through which air is drawn in from a surface being cleaned, an agitator unit having bristles at predetermined intervals, a turbine unit rotatably supported within the lower casing and being rotated by the air drawn into the turbine brush by suction force generated by the vacuum cleaner, and a power transfer unit to cause the agitator unit and the turbine unit to rotate in association with each other. When cleaning surfaces having loose material, such as a blanket or other fabric, the suction slot of the lower casing includes a plurality of ribs to inhibit the blanket or other fabric from being drawn into the brush body by the suction force generated by the vacuum cleaner. The bristles are in contact with the surface being cleaned by passing through apertures in the suction slot defined by the plural ribs. The turbine brush enables a user to conveniently clean surfaces having loose material by inhibiting the blanket or fabric from being caught by the turbine brush. Preferably, the upper casing comprises a transparent material.

Description

technical field [0001] The present invention generally relates to a turbo brush for a vacuum cleaner, and more particularly to a turbo brush for a vacuum cleaner having suction-preventing ribs at the bottom of the turbo brush. Background technique [0002] figure 1 is a perspective view of a conventional vacuum cleaner. The turbo brush 7 of the vacuum cleaner is in contact with and moves along the surface to be cleaned, and forms a suction path from the surface to be cleaned to the main body 9 of the vacuum cleaner. Thus, air containing dust and dirt that has been removed from the surface to be cleaned is sucked through the swirl brush 7 into the main body 9 of the vacuum cleaner. [0003] The suction path includes an extension pipe 8a connected to the turbo brush 7, an operating handle 8b, and a flexible hose assembly 8c. [0004] If the surface to be cleaned is a fabric, such as a carpet, dust and dirt can be effectively removed if they are separated from the surface to...

AI Technical Summary

Problems solved by technology

As a result, the cleaning operation is under stress and the vacuum cleaner body 9 can be overloaded, causing mechanical failure

[0017] Secondly, since the upper casing 11 of the conventional turbo brush 7 is made of translucent or opaque plastic material, it is difficult to observe the inside of the brush body 10

When the upper case 11 is opened to allow the user to check the internal state of the brush body 10, the opening / closing structure is complicated, making it difficult to operate

[0018] Third, when opening and turning the upper housing 11 of the brush body 10, the impeller 30 is easily disengaged from the brush body 10 due to the force of gravity, and the parts containing the unit will also move or leave their proper positions
