Toppled alcohol lamp with self-extinguishing function

Abstract

The invention discloses a toppled alcohol lamp with a self-extinguishing function. The toppled alcohol lamp with the self-extinguishing function comprises a bottle body, a cotton thread and a fixing plug, wherein the fixing plug is clamped at the upper end of the bottle body, the cotton thread is arranged in the bottle body, one end of the cotton thread penetrates through the fixing plug, a cavityis formed in the fixing plug, the cavity comprises a left movable cavity and a right movable cavity, the left movable cavity communicates with the right movable cavity, a left sliding block is connected in the left movable cavity in a sliding mode, a traction line is fixedly connected below the left sliding block, a right sliding block is slidably connected in the right movable cavity, a memory metal sheet is fixedly connected to the right sliding block, and an annular groove is formed in the bottom of the fixing plug. According to the toppled alcohol lamp with the self-extinguishing function, when the alcohol lamp is toppled, the traction line is pulled by the tilting of a toppled bottle body, the memory metal sheet is extruded out of the cavity through gas, the memory metal sheet is subjected to deformation and folded under the high-temperature action of flame, so that the flame is covered, and then oxygen is isolated to achieve a fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a self-extinguishing alcohol lamp by pouring. Background technique [0002] Alcohol lamp is a heating tool fueled by alcohol. It is widely used in laboratories, factories, medical treatment, scientific research, etc. Since it does not produce smoke during combustion, it can also achieve the purpose of sterilization by burning equipment. Because of the heat generated during the burning process of the alcohol lamp, other experimental materials can be heated, and its heating temperature can reach above 400-1000°C. [0003] When elementary and middle school students conduct experiments in the laboratory, they often use alcohol lamps. Due to the limitation of operation ability of primary and middle school students, if there is a collision during the experiment, the alcohol lamp on the test bench is easy to fall due to the collision. The existing The glass bottle of the...

Problems solved by technology

[0003] When elementary and middle school students conduct experiments in the laboratory, they often use alcohol lamps. Due to the limitation of operation ability of primary and middle school students, if there is a collision during the experiment, the alcohol lamp on the test bench is easy to fall due to the collision. The existing The glass bottle of the alcohol lamp can withstand the impact well, but the poured alcohol lamp is still burning even though it is not broken. The students are afraid of the flame and will not lift up the alcohol lamp in time or extinguish the flame. The alcohol lamp that burns abnormally , the flame is directly in contact with the bottle body, the glass is roasted at high temperature, and there is a danger of breaking. The broken glass is very harmful, and the alcohol will overflow during the breaking process, resulting in a large area of ​​burning, which is very unsafe for students
