Abstract

The invention discloses a heating device for a chemical experiment, and relates to the technical field of chemical experiment instruments. The heating device comprises a bottle body and a cotton wick.The bottle opening is connected with a leakage-proof device; the leakage-proof device comprises an isolation pipe connected with the bottle opening; a built-in sleeve is arranged in the bottle body;water seepage holes are formed in the left and right sides of the lower part of the built-in sleeve; the outer side of the isolation sleeve is fixedly sleeved with a plurality of sealing rings; the upper end of the isolation tube is inserted and hermetically connected with a wick seat; a plurality of separation boards are fixed in the isolation pipe from top to bottom; a flame-proof device is arranged at the upper part in the isolation pipe; a fire cutoff device is arranged on the lamp wick seat; the lamp wick seat is sleeved and matched with a lamp cap; the flame-proof device comprises a reaction box; a bearing net is fixed in the middle in the reaction box; a plurality of air outlets are formed in the upper end of the reaction box; the fire cutoff device comprises a barrel-shaped wick cap; a balance weight ring is fixedly connected to the periphery of the lower portion of the wick cap. According to the heating device, the safety of the alcohol lamp in use is improved, and harm is notlikely to be formed when the alcohol lamp topples over.

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...
