Suction nozzle device for use in vacuum cleaner

Abstract

A suction nozzle device connected to a vacuum cleaner for cleaning beddings such as blankets. The suction nozzle device includes a nozzle which is coupled through a suction passage to an electric blower of the vacuum cleaner and which has a suction opening at its end portion which is arranged so as to face an object to be cleaned. Also included is a pair of rotatable rollers each of which is cylindrically shaped and has on its outer circumferential surface a plurality of tooth-portions which are radially protruded from said outer circumferential surface. The suction opening thereof is positioned to be interposed between the pair of rotatable rollers. Each of the tooth-portions is elongated by a predetermined length in the directions of the axes of the rotatable rollers. Each of the rotatable rollers is divided into a plurality of sections each of which has a predetermined number of the tooth-portions and is formed so as to have at least a flat portion between the tooth-portions. The adjacent ones of the plurality of sections are disposed so that their flat portions are in 180.degree. out-of-phase relation to each other.
