Abstract

The invention belongs to the technical field of chemical experiments, in particular to a high school chemical experiment table. Aiming at the problem that the high school chemical experiment table has a single function and a high risk factor in use, the following scheme is proposed, including the table board, and the four corners of the bottom outer wall of the table board are uniform. There are supporting legs, and one side of the bottom outer wall of the table board is provided with a locker, and the other side of the bottom outer wall of the table board is provided with a waste cabinet, the top outer wall of the table board is provided with an adsorption cover, and the two sides of the outer wall of one side of the adsorption cover are All are provided with lamp holders, and the inner wall of the lamp holder is clamped with an LED lamp, and the outer wall of one side of the adsorption cover is provided with a vent, and the inner wall of the vent is provided with a waste gas channel. The invention can timely extract the waste gas produced by the chemical experiment and discharge it outside, effectively reducing the harmfulness of the toxic waste gas to the health of students, and has high safety performance. At the same time, the distilled water after distillation can be used for experiments at any time, which is convenient and fast, and an alcohol lamp holder is set in the protective box. The anti-slip protrusions evenly distributed at equal distances increase the friction.

Description

technical field

[0001] The invention relates to the technical field of chemical experiments, in particular to a high school chemical experiment table. Background technique

[0002] Chemistry in high school is a natural subject based on experiments. Doing experiments well plays a very important role in stimulating students' interest in learning and cultivating students' intelligence and hands-on ability. In order to improve students' level, teachers usually use experimental methods Teaching methods to enhance students' interest in learning and enhance students' memory.

[0003] At present, the high school chemical experiment table has the same structure as the general desk. It is mainly composed of the table top and table legs, and its function is relatively single. Moreover, some chemical experiments involving toxic gases have begun in high school chemical experiments. After a long time of experimental study, toxic gas Failure to discharge outdoors as soon as possible will ...
