Claims

[Claims for Utility Model Registration] (1) In a drive device housed in a case of a suction nozzle, which is equipped with a rotor that is driven and rotated by the drive device, the rotor has a notch on its axis. a protrusion and a low level part are provided there, and a brush for implanting bristle material in this low level area is installed close to the protrusion, parallel to the above protrusion, and radially about the axis of the roller, and when the brush is not released, A suction nozzle for a vacuum cleaner, wherein the outer diameter of the end is larger than the outer diameter of the tip of the protrusion, and the open outer end of the brush slightly protrudes from the tip of the protrusion of the rotor. rotating rotor. (2) The cross-section of the rotor is circular, a part of this circular cross-section is cut out to create different steps, these are made continuously along the axis of the rotor, and bristle material is implanted in the lower steps to create a brush. 2. The rotating rotor of a suction nozzle for a vacuum cleaner according to claim 1, wherein the rotor is planted in parallel with the protrusions of the different stages. (3) A concave groove or convex groove is provided along the axis of the rotor, a string-like conduit is fitted into the concave groove or convex convexity to form a protrusion, and the concave groove or protrusion is fitted along with and close to the concave groove or protrusion. 2. The rotating rotor of a suction nozzle for a vacuum cleaner according to claim 1, wherein a brush is provided by planting bristle material. (4) Make the cross section of the rotor circular, cut out a part of this circular cross section to create a step difference or a flat part, and align it with the protrusion that is the high step part of the step difference, or do not provide a protrusion. For flat parts, a groove or a protrusion is provided on a part of the flat part, and a string-like structure is fitted into the groove or protrusion to form a protrusion. 2. The rotating rotor of a suction nozzle for a vacuum cleaner according to claim 1, wherein the rotor is formed into a uniform shape and is provided with a brush by planting bristles along and close to the rod. (5) A rotary rotor for a suction nozzle for a vacuum cleaner according to any one of items 1 to 4, wherein the cross section of the rotor is a polygon, an ellipse, or an irregular shape corresponding to a circle.
