Test tube cleaning device for chemical experiments

Abstract

The invention relates to the technical field of instruments and meters, and discloses a test tube cleaning device for chemical experiments. The test tube cleaning device comprises a base, a lifting rod is fixedly mounted at the top of the base, a control box sleeves one end, far away from the base, of the lifting rod, and a cleaning rod is arranged on one side, far away from the lifting rod, of the control box. The cleaning rod penetrates through the control box and extends to the outer side, and a motor is fixedly installed on the extending part of the cleaning rod. According to the test tube cleaning device for the chemical experiments, when cleaning cotton makes contact with the inner wall of a test tube, the cleaning cotton is driven to move under the action of extrusion force, when the cleaning cotton moves, an arc-shaped pushing plate and an extrusion rod are driven to move, and when the extrusion rod moves, a water storage pipe is extruded; and water in the water storage pipe enters the cleaning cotton under the action of extrusion force, so that the purpose of cleaning the test tube is achieved, the practicability of the device is enhanced, and the safety of workers is protected.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a test tube cleaning device for chemical experiments. Background technique [0002] The test tube is a commonly used instrument in the chemical laboratory. It is used as a reaction container for a small amount of reagents. It is used at room temperature or when heated. [0003] The existing test tube cleaning work is generally done by manual cleaning, and choosing manual cleaning of chemical test tubes is a job that is extremely harmful to the human body, and the work efficiency is extremely low and the cost is high; moreover, chemical test tubes are fragile items , The test tube is often broken due to improper operation, resulting in a waste of resources and a large waste of labor. Contents of the invention [0004] The object of the present invention is to provide a test tube cleaning device for chemical experiments to solve the problems raised in the above-me...
