In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an electronic test-tube brush is used in laboratory, includes gear box and handle, the bottom at the gear box is installed to the handle, be provided with power module and motor in the handle, power module carries out the electricity through the wire and is connected with the motor, be provided with the switch on the wire, the switch mounting is on the shell of handle, install driving gear and driven gear in the gear box, driving gear and driven gear mesh, be connected with the transmission shaft on the output shaft of motor, motor one end and driving gear connection are kept away from to the transmission shaft, the last test tube brush axle of installing of driven gear, the epaxial test tube brush hair of installing of test tube brush.

Preferably, driven gear is provided with four altogether, four driven gear evenly distributed is in the driving gear outside, every all install test tube brush axle on the driven gear, every the epaxial test tube brush hair of all installing of test tube brush.

Preferably, the test tube bristles are cylindrical in shape, and the diameter of the test tube bristles is greater than the inner diameter of the test tube.

Preferably, the outer side of the handle is sleeved with a rubber anti-slip sleeve.

Preferably, the power module adopts a battery.

Compared with the prior art, the beneficial effects of the utility model are that: the small direct current electric system in the handle provides electric power to electrically clean the test tube, so that manual operation is reduced; can carry out the cleaning operation to four test tubes simultaneously through four test tube brush hairs that set up, improve the cleaning efficiency.
