Abstract

The invention provides a test-tube brush for a chemical experiment in a senior middle school and belongs to the technical field of chemical experiment containers. For solving the problem that an existing product cannot clean the inner wall and the outer wall of a tubular container simultaneously, a brush handle is fixed to the upper end of a linkage device, a micro motor is arranged in the brush handle, the outer end of the micro motor is connected with an inner brush head through a rotary shaft, and the inner brush head is of a cylindrical structure. An outer brush head is fixedly installed at the lower end of the linkage device and is of a cylindrical structure, and the inner brush head is located in the outer brush head. The test-tube brush for the chemical experiment in the senior middle school can simultaneously clean the outer wall and the inner wall of the tubular container for the chemical experiment.

Description

technical field [0001] The invention relates to a test tube brush, in particular to a test tube brush for high school chemical experiments, which belongs to the technical field of chemical experiment container cleaning. Background technique [0002] In the chemical laboratory, there are many kinds of containers that need to be cleaned, such as test tubes, measuring cylinders, etc. At present, most of them use equipment such as straight rod type test tube brushes or test tube cleaning machines. The test tube cleaning machine is large in size, high in cost, and complicated to operate; most of the straight rod type test tube brushes are used to clean the residual chemical agents inside the test tubes, and in chemical experiments, due to human factors, it is very easy to spill the chemical agents to the outside of the container. As a result, there are chemical residues on the outer wall of the container. Since the duration of the general experiment is very long, after the experi...
