Abstract

The invention discloses a protective cover for chemical experiments in the senior high school. The protective cover comprises a bottom cavity, a cover casing, an operating panel and discharging plates, wherein the bottom cavity is of a semi-closed structure provided with an opening in the top end; clamp slots are fixed in the position, close to the top end, of the inner side of the bottom cavity;the bottom end of the cover casing is clamped on the inner sides of the clamp slots; a ventilating opening is formed in the top end of the cover casing; a transparent glass plate is inlaid in one sideof the bottom cavity; a support frame is fixed on the bottom surface of the inner side of the bottom cavity; the operating panel is fixed on the support frame and comprises an outer ring plate and amesh plate, a center hole is formed in the center of the outer ring plate, and the outer ring plate is fixed on the support frame. The clamp slots are fixed in the position, close to the top end, of the inner side of the bottom cavity, the cover casing provided with the ventilating opening is clamped on the inner sides of the clamp slots in the bottom cavity, so that ventilation performance of theprotective cover is improved, improvement of the ventilation performance of the protective cover for the chemical experiments in the senior high school is facilitated, and the protective cover is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of high school chemical experiment appliances, in particular to a protective cover for high school chemical experiments. Background technique [0002] Chemistry is a kind of natural science. It studies the composition, properties, structure and changing laws of substances at the molecular and atomic levels; it is the science of creating new substances. The world is made up of matter, and chemistry is one of the main methods and means that humans use to understand and transform the material world. It is a discipline with a long history and vitality, and its achievements are an important symbol of social civilization. There are two forms of change in chemistry: chemical change and physical change. Chemistry in the 20th century is a science based on experiments. Experiment and theory have always been two aspects of chemical research that depend on each other and promote each other. After entering the 20th cen...
