A proper amount of cleaning liquid is poured in from the liquid inlet and is attached to the glue cotton layer or directly enters a test tube through the flow distributing channels, and then the brush handle can be rotated to clean the test tube; the glue cotton layer which is coated on the brush head not only can effectively clean spots in the test tube, but also can protect the test tube from being damaged; and when the test tube cleaning brush is used, the brush cap is sheathed on an opening of the test tube, so that the cleaning liquid can not be splashed from the opening of the test tube; and the concave edge of the brush cap can lead the brush cap to be tightly buckled on the opening of the test tube, so that the brush cap can not fall off the test tube during the cleaning of the test tube.
Description
Technical field
The utility model relates to a kind of cleaning means of chemical experiment articles for use, relates in particular to a kind of instrument that cleans test tube.
Background technology
At present, test tube is students chemical experiment and the most frequently used equipment of chemical analysis, and its use amount is big, generally all is to have been cleaned by teacher having tested the back, cleans and clean the hairbrush that passes through that test tube generally can only.The existing test-tube brush that is used to clean test tube generally comprises brush holder support, brush and bristle, because the end of brush is a flat, and so easy damage test tube bottom; In addition, bristle comes off easily, is out of shape, and clean not thorough, influence next time experiment is used, owing to after test-tube brush puts into test tube, can't deploy cleaning fluid in vitro, need earlier test-tube brush to be taken out to operate again, so not only complex operation, and waste cleaning fluid has increased burden to teacher.In the engineering that test tube cleans, cleaning fluid is easy to spill from the test tube mouth, drops on the experimental bench, and the testing stand of making dirty easily need be cleared up plan to testing stand, increases the teacher's that knows clearly workload.
The utility model content
Technical problem to be solved in the utility model provides a kind of test tube simple in structure, easy to use, not fragile and can prevent the test tube cleaning brush that cleaning fluid splashes.
For solving the problems of the technologies described above, the technical solution of the utility model is: the test tube cleaning brush, comprise brush holder support, the front end of described brush holder support is equipped with brush, the end of described brush holder support is equipped with brush holder, at described brush holder, the center of brush holder support and brush is equipped with the fluid passage that is interconnected, the end of described brush holder is provided with the inlet that is communicated with described fluid passage, the surface of described brush is provided with the collodion layer, be provided with split channel between fluid passage in the described brush and the described collodion layer, brush holder support between described brush holder and the described brush is provided with the adjustable brush cap in position, and described brush cap is the rubber brush cap, and described brush cap is provided with the edge of indent.
As a kind of optimized technical scheme, described split channel is the split channel that tilts to described brush front end.
Owing to adopted technique scheme, the test tube cleaning brush, comprise brush holder support, brush and brush holder, be equipped with the fluid passage that is interconnected at the center of described brush holder, brush holder support and brush, the end of described brush holder is provided with the inlet that is communicated with described fluid passage, the surface of described brush is provided with the collodion layer, be provided with split channel between fluid passage in the described brush and the described collodion layer, brush holder support between described brush holder and the described brush is provided with the adjustable brush cap in position, described brush cap is the rubber brush cap, and described brush cap is provided with the edge of indent.An amount of cleaning fluid is poured in the fluid passage from inlet, cleaning fluid is through split channel, attached to the collodion layer or directly enter in vitro, rotating brush holder gently just can clean up test tube, the collodion layer that coats on the brush both can be removed invisible spectro spot effectively, can also protect test tube to avoid infringement; During use, will brush cap sleeve on the test tube mouth, and can prevent that cleaning fluid from splashing out from the test tube mouth, the concave shaped edge that is provided with on the brush cap can make the brush cap be buckled in tightly on the test tube mouth, prevents to brush cap and comes off from test tube in cleaning process.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: the 1-brush; The 2-brush holder support; The 3-brush holder; The 4-fluid passage; 5-collodion layer; The 6-split channel; The 7-inlet; 8-brushes cap; The 9-test tube.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in drawings, the test tube cleaning brush, comprise brush holder support 2, the front end of described brush holder support 2 is equipped with brush 1, the end of described brush holder support 2 is equipped with brush holder 3, at described brush holder 3, the center of brush holder support 2 and brush 1 is equipped with the fluid passage 4 that is interconnected, the end of described brush holder 3 is provided with the inlet 7 that is communicated with described fluid passage 4, the surface of described brush 1 is provided with collodion layer 5, be provided with split channel 6 between fluid passage 4 in the described brush 1 and the described collodion layer 5, the liquid outlet of described split channel 6 is compared to the front end of inlet near described brush 1, it is the split channel 6 that is provided with between fluid passage 4 and the described collodion layer 5 in the described brush 1 to described brush 1 front end inclination, brush holder support 2 between described brush holder 3 and the described brush 1 is provided with brush cap 8, the position of described brush cap 8 on described brush holder support 2 can be regulated, and described brush cap 8 is the rubber brush cap, and described brush cap 8 is provided with the edge of indent.
