Abstract

The invention discloses a waterproof detachable electric type test tube brush which comprises a power assembly, an upper rod piece, a connection assembly, a lower rod piece and bristles, wherein the power assembly comprises a battery shell, an upper shell, a lower shell, a motor seat, a shaft coupler, a bearing pedestal, a bearing, a connection piece, sealing rings, a battery and a motor; the battery is positioned in the battery shell; the battery shell is fixedly connected with the lower shell; the lower shell is mechanically connected with the upper shell; the motor seat is mounted in the lower shell; a motor is mounted on the motor seat; an output shaft of the motor is connected with the connection piece through the shaft coupler; the bearing is mounted on the shaft at the upper end of the connection piece and is mounted in the bearing pedestal; the upper rod piece is connected with the interior of a longitudinal hole of the connection piece; the lower end of the upper rod piece is connected with a lower rod piece through the connection assembly; the bristles are fixedly arranged on the lower rod piece; sealing rings are embedded into the lower ends of the upper shell and the lower shell; a sealing ring is embedded into the upper end of the bearing pedestal. The electric type test tube brush is waterproof under the assistance of the sealing rings, can clean a test tube and is convenient to detach.

Description

【Technical field】 [0001] The invention relates to the technical field of test tube brushes, in particular to the technical field of a waterproof detachable electric test tube brush. 【Background technique】 [0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction vessels for small amounts of reagents and are used at room temperature or under heating. Many test tubes are often used when doing various tests, and the cleaning of test tubes is generally done manually, using a test tube brush, which not only takes a long time to clean, but also is not very clean, time-consuming and laborious. [0003] Although there is a device for mechanized cleaning of test tubes, due to the relatively high price of the equipment, the high cost of use, and the lack of portability, it has many limitations. 【Content of invention】 [0004] The purpose of the present invention is to solve the problems in the prior art, and propose a waterproof and detac...
