Chemical experiment cleaning device

Abstract

The invention relates to the technical field of chemical appliance cleaning, in particular to a chemical experiment cleaning device. According to the chemical experiment cleaning device, the using limitation can be reduced; meanwhile, test tubes with various sizes can be cleaned at the same time, and the usability is improved; and the chemical experiment cleaning device is conveniently stored, andthe using reliability is improved. The chemical experiment cleaning device comprises a motor, a battery box, a switch button and a handle, wherein the motor, the battery box and the switch button areall arranged on the handle. The chemical experiment cleaning device further comprises a storage box, a fixing ring, a supporting plate and a fixing piece, wherein the storage box is internally provided with a placement cavity, and the supporting plate is arranged in the placement box. The chemical experiment cleaning device further comprises a fixing rod, a first fixing block and a first connection piece, wherein the fixing rod is arranged at the bottom end of a rotating shaft, and the outer side wall of the first connection piece is provided with first bristles. The chemical experiment cleaning device further comprises a plurality of sets of fulcrum bars, a plurality of sets of second fixing blocks and a plurality of sets of second connection pieces, wherein the outer diameters of the multiple sets of second connection pieces are different, and the outer side walls of the multiple sets of second connection pieces are all provided with second bristles. The chemical experiment cleaningdevice further comprises a storage case, wherein the storage case is put in a storage cavity.

[0002] As everyone knows, the chemical experiment cleaning device is a kind of auxiliary device that is used to clean the test tube after the chemical experiment, so that it can be used next time, and it is widely used in the teaching field; the existing chemical experiment cleaning device includes motor, battery Box, switch button and handle, motor, battery box and switch button are all arranged on the handle, battery is placed in the battery box, and the motor and switch button are connected with the battery box through wires, the bottom output end of the motor is provided with a rotating shaft, The bottom end of the rotating shaft is provided with a brush head, and the outer wall of the brush head is provided with bristles; when this chemical experiment cleaning device is used, the cleaning agent is poured on the brush head, and then the test tube is placed on the outer side of the brush head so that the bristles and the inner wall of the test tube Contact, then press the switch button, control the motor to drive the brush head on the rotating shaft to rotate, brush off the dirt on the inner wall of the test tube through the bristles, remove the test tube after brushing, and rinse the cleaning solution with clean water. In the use of this chemical experiment cleaning device, it is found that it can only clean the test tubes, and the use limitations are relatively high; and the radius of the brush head is fixed, so the size of the test tubes that can be cleaned is fixed, and the usability is limited; Will retain some moisture and tend to stain the placement area during storage, resulting in limited reliability
