Abstract

The invention discloses a middle school chemistry teaching instrument cleaning device. The device comprises a baseplate; the top of the baseplate is fixedly connected with a mounting frame; the top of the mounting frame is fixedly connected with a protective cover; the top of the inner wall of the protective cover is rotationally connected with a rotating shaft through a bearing; the bottom end of the rotating shaft penetrates through the mounting frame, and extends into the mounting frame; a first bevel gear sleeves the outer surface, positioned in the protective cover, of the rotating shaft; and a motor is fixedly connected into the protective cover at the top of the mounting frame through a connecting block. The device relates to the technical field of teaching instrument cleaning equipment. The middle school chemistry teaching instrument cleaning device greatly improves the cleaning effect, improves the cleaning efficiency, has no need of a lot of time to clean cup-shaped and drum-shaped experimental instruments, preferably relieves the experimental burdens of experimenters, realizes quick and convenient cleaning of the cup-shaped and drum-shaped experimental instruments, and is more convenient for the experimenters to use the experimental instruments.

Description

technical field [0001] The invention belongs to the technical field of teaching instrument cleaning equipment, in particular to a middle school chemistry teaching instrument cleaning device. Background technique [0002] Chemistry is a subject based on experiments. Chemical experiments are the foundation of middle school chemistry teaching and one of the basic ways to stimulate students' interest in learning, make them actively acquire knowledge, improve scientific literacy, and cultivate innovation ability. Therefore, it is of great significance to pay attention to and improve the teaching of chemistry experiments to improve the quality of chemistry teaching in junior high schools. [0003] Experiments are the basis for students to deeply understand the basic theory of chemistry. In the discipline of chemistry, the proposal, development and improvement of any theory (or hypothesis) must be based on certain experimental facts, such as: the experimental basis for the layered...
