Abstract

본 발명은 진공청소기의 흡입브러쉬에 관한 것으로, 특히 흡입브러쉬의 네크(neck)부 내측으로 위치한 홉음재를 유동없이 견고하게 장착되는 고정수단을 마련함으로서, 흡입브러쉬에 의한 청소 작업시,발생하는 소음을 저하시킬 수 있도록 한 흡입브러쉬의 저소음장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction brush of a vacuum cleaner, and in particular, by providing a fixing means for firmly mounting a hop sound material located inside the neck portion of a suction brush without flow, thereby generating noise during a cleaning operation by the suction brush. It relates to a low noise device of the suction brush to lower the.

본 발명은 네크부(205)의 제1내주면 (210)에 밀착되는 원통형의 흡음재(220)와 상기 흡음재(220)의 외주면(220ａ)이 상기 제1내주면 (210)와 압착 고정되도록, 상기 흡음재(220)의 내부공간에 끼워지는 고정수단(221)을 포함함을 특징으로 하는 흡입브러쉬의 저소음 장치를 제공한다.The present invention provides a cylindrical sound absorbing material 220 in close contact with the first inner circumferential surface 210 of the neck portion 205 and the outer circumferential surface 220a of the sound absorbing material 220 is fixed to the first inner circumferential surface 210, the sound absorbing material It provides a low noise device of the suction brush, characterized in that it comprises a fixing means 221 fitted into the inner space of (220).
