The utility model discloses a brush of quick self - cleaning container, including handle, a plurality of brush hair, be located the inside shifting sledge of handle and can be on the shifting sledge reciprocating motion's rotating electrical machines, install the annular piece that draws in in on the lower extreme inner wall of handle, the rotating electrical machines with draw in the stopper of arranging restricted rotation motor displacement between the piece in, install the rotation axis on the output of rotating electrical machines, the one end of brush hair is passed and is drawn in drawing in in of piece in direct behind the hole perhaps indirect fixation is on the rotation axis, the rotating electrical machines is kept away from or is close to when drawing in in piece, the brush hair is the linearity or expands umbelliformly outward. When the brush hair was the linearity, being convenient for, it from the business turn over of bottleneck of erlenmeyer flask, expanded outside the brush hair is when umbelliform for the brush hair fully contacts its inner wall sanitization with the erlenmeyer flask of being convenient for with the inner wall of erlenmeyer flask.
