Alcohol lamp used for chemical experiment

Abstract

An alcohol lamp for chemical experiments, which relates to a chemical experiment tool, in which a wick sleeve (2) is arranged at the upper end of the circular lamp holder (10) on the lamp body (4), and the lower part of the wick sleeve is sealed and placed on In the hollow of the lamp holder (10), the upper part of the wick sleeve is clamped on the hollow edge surface of the lamp holder, and a necking snap ring (8) is provided on the upper periphery of the wick sleeve, and the necking snap ring wears Through the round hole (9) on the upper surface of the lamp cap (3) and clamped on the edge of the round hole, the lamp cap is buckled on the upper end of the lamp holder, and an additional cap (6) is provided on the upper part of the lamp cap. The cap is fastened on the wick sleeve (2) and the lamp cap; by providing an additional cap on the lamp cap and clamping the lamp cap on the wick sleeve, the purpose of connecting the lamp cap and the lamp body is achieved. It avoids the situation that the hand is easy to be burned during the process of extinguishing the flame of the alcohol lamp in which the lamp cap and the lamp body are separated, and the situation that the lamp cap is easily lost when the lamp cap is misplaced.

Description

technical field [0001] The invention relates to a chemical experiment appliance, in particular to an alcohol lamp for chemical experiments. Background technique [0002] As we all know, many experiments in chemical experiments are inseparable from alcohol lamps. Alcohol lamps are composed of five parts: lamp body, cotton lamp rope (cotton wick), porcelain wick, lamp cap and alcohol; It is separate from the lamp cap. When extinguishing the lamp flame, you need to pick up the lamp cap to cover it. If you do not operate it properly, it will cause burns to your hands. Moreover, the lamp cap is easy to lose when placed anywhere during the experiment. After the experiment is over, you have to look for it everywhere. Lamp caps cause unnecessary trouble. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the present invention discloses an alcohol lamp for chemical experiments. By providing an additional cap on the lamp cap and c...
