Abstract

The invention discloses a test tube brush. The test tube brush comprises a hand-holding part and a test tube brush body, wherein the test tube brush body comprises brush rods and brush bristles, a micro motor and an electricity storage device are fixedly arranged in the hand-holding part, a rotation rod is fixedly arranged at the lower part of the micro motor, the rotation rod extends out of the hand-holding part, a telescopic rod is fixedly arranged at the lower part of the rotation rod, a connecting part is movably arranged at the lower part of the telescopic rod, the brush rods are hinged to the circumferential direction of the lower end of the connecting part, a sliding button and a groove are arranged on the connecting part, a support rod is fixedly arranged at the lower part of the connecting part, a base is movably arranged on the support rod, support frames are hinged to the circumferential direction of the base, and the other ends of the support frames are hinged to the brushrods. The invention provides the test tube brush which is suitable for washing various instruments, meanwhile, during use, manpower can be saved, and in addition, the brush bristles can be replaced, so that the cost is saved.

Description

technical field [0001] The invention belongs to the field of experimental equipment, in particular to a test tube brush. Background technique [0002] Test tubes, distillation flasks, beakers, volumetric flasks and other instruments are often used in experiments in the fields of biology, chemistry, and medicine. These instruments need to be cleaned after use for the next use. The most commonly used cleaning of these instruments is the test tube brush. . [0003] Common test tube brushes on the market are made of a metal wire twisted into a brush rod in a twisted shape, and then the brush is wrapped in the brush rod. Because these test tube brushes have a fixed shape, different types of test tube brushes need to be replaced when scrubbing different instruments, and instruments with curved inner walls are not easy to clean. At the same time, these test tube brushes need to be brushed by the user, which is not conducive to people's use. . [0004] In order to solve the above...
