AI Technical Summary
Technical Problem
In secondary school chemistry teaching, the existing combustion spoons result in insufficient contact between combustible materials and oxygen, making the combustion phenomenon less noticeable and affecting students' observation and data collection.
Method used
Design a gas-conducting glass combustion spoon, including a conduit and a spoon body. The conduit is connected to an oxygen cylinder, and a combustible material is placed inside the spoon body to increase the continuous contact area between the combustible material and oxygen. The airflow is controlled by a gas supply pipe.
Benefits of technology
It achieves intense and complete combustion of combustibles, enhances the observation of combustion phenomena, saves oxygen, and can fix combustibles to prevent movement.

Abstract
The utility model relates to a chemical experiment instrument, in particular to a glass combustion spoon capable of guiding gas and a gas guiding system. A glass burning spoon capable of guiding gas comprises a guide pipe and a spoon body connected with one end of the guide pipe in a communicating mode. During actual use, one end of the guide pipe is communicated with an oxygen bottle, and combustible materials are placed in the spoon body and ignited, so that the combustible materials can be in continuous and sufficient contact with oxygen, the combustible materials are combusted more violently, and the combustion phenomenon observed by students is more obvious. The air guide system comprises an air supply pipe and the glass combustion spoon capable of guiding air, one end of the air supply pipe is communicated with the guide pipe, the other end of the air supply pipe is used for being communicated with an oxygen bottle, and the air supply pipe is provided with a valve body used for controlling the air flow. The valve body is connected to the air supply pipe, so that the air flow can be adjusted according to different combustible materials and the quantity of the combustible materials.
