The invention discloses a heating device for chemical experiments, which relates to the technical field of chemical experiment instruments. It includes a bottle body and a cotton wick; a leak-proof device is connected to the bottle mouth; the leak-proof device includes an isolation tube connected to the bottle mouth; a built-in sleeve is arranged in the bottle body; hole; the outer side of the isolation tube is socketed and fixed with multiple sealing rings; the upper end of the isolation tube is plugged and sealed with a wick holder; inside the isolation tube, there are multiple partitions fixed from top to bottom; the upper part of the isolation tube is provided with a flameproof device; the wick holder A fire breaker is provided on the top; a lamp cap is fitted on the wick seat; the flameproof device includes a reaction box; The fire device includes a barrel-shaped wick cap; the outer periphery of the lower part of the wick cap is fixedly connected with a weight ring. The invention has the beneficial effects of improving the safety of the alcohol lamp during use, and not easily causing harm when it is dumped.

Description

technical field [0001] The invention relates to the technical field of chemical experiment instruments. Background technique [0002] In routine chemical experiments, the alcohol lamp is used as a heating tool to heat test tubes, etc., and is placed on the test bench for fixed use. However, there are many safety hazards in the traditional alcohol lamp, especially when it is poured, it is easy to cause the alcohol in the bottle to flow out, causing a fire; etc. causing unsafe hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heating device for chemical experiments aiming at the technical deficiencies mentioned above. Improve the safety of the alcohol lamp when it is in use, and it is not easy to cause harm when it is dumped. [0004] The technical scheme adopted by the present invention is: provide a heating device for chemical experiments, including a bottle body and a cotton wick; It is the mouth of...
