Description
Technical field
The utility model relates to a kind of bottle brush, especially for the round bottom bottle brush of cleaning round-bottomed flask.
Background technology
In chemical experiment, usually use round-bottomed flask as reaction vessel, after the completion of reaction, cleaning round-bottomed flask is also very important work, the clean of flask tests the prerequisite of normally carrying out, but there is no the brush of suitable round-bottomed flask at present, can only replace with test-tube brush, in cleaning round-bottomed flask process, in order to clean the round bottom of round-bottomed flask, often bending test-tube brush carrys out the bending round bottom of clean round-bottomed flask.Conventional test-tube brush is assembled by bifilar iron wire, bristle, principle can be bent, but in fact repeatedly bend and easily damage test-tube brush, reduce test-tube brush service life, and bend test-tube brush to waste time and energy, and also test-tube brush must be bent into straight-bar again after finishing using, be not only inconvenient to use, and cleaning effect be undesirable.
Therefore, a kind of can either be good clean round-bottomed flask, have again and become the key of dealing with problems compared with the round bottom bottle brush of long life.
Utility model content
The purpose of this utility model is to provide a kind of clean round-bottomed flask that can either be good, has again the round bottom bottle brush compared with the long life.
For achieving the above object, the utility model adopts following technical scheme, and a kind of round bottom bottle brush, comprising:
Brush holder, is provided with projection in brush holder front portion, and for supporting bristle;
Annulus, is set on brush holder, in the middle part of annulus, is provided with draw-in groove, and for fixing spring;
Multiple spring, is disposed in parallel in the surrounding of brush holder, and one end and the brush holder front end of spring are fixedly linked, and the other end of spring is fixedly connected with annulus, and for fasten bristles;
Bristle, is arranged in array, and is wrapped on described spring.
As preferred further, described draw-in groove and protrusions.
As preferred further, the number of described multiple spring is 4.
As preferred further, described brush holder is made of plastics.
As preferred further, described spring is made up of macromolecular material.
As preferred further, described bristle is made up of nylon yarn.
As preferred further, described bristle is alternately made up of long brush hairs and short bristles.
As preferred further, described long brush hairs is soft bristle, and described short bristles is hard bristle.
The beneficial effects of the utility model are: the spring 1, being arranged on the surrounding of brush holder can bend, and the bristle on spring is effectively fitted drag, effectively can clean round-bottomed flask; 2, because whole round bottom bottle brush is made by nonmetallic materials, thus not easily get rusty, longer service life; 3, soft long brush hairs and hard short bristles are alternately arranged, and cleaning effect is better.
