In order to achieve the purpose, the invention adopts the following technical scheme:
an alcohol lamp capable of automatically extinguishing toppling comprises a bottle body, a cotton thread and a fixed plug, wherein the fixed 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 fixed plug, a cavity is formed in the fixed plug and comprises a left movable cavity and a right movable cavity, the left movable cavity is communicated with the right movable cavity, a left sliding block is connected in the left movable cavity in a sliding mode, a traction wire is fixedly connected below the left sliding block, a right sliding block is connected in the right movable cavity in a sliding mode, a memory metal sheet is fixedly connected on the right sliding block, a ring-shaped groove is formed in the bottom of the fixed plug, a plurality of balls are arranged in the ring-shaped groove in a sliding mode, a connecting shaft is fixedly connected below one of the balls, the traction wire penetrates through the connecting shaft, an iron block is fixedly connected to one end, far away from the, and the bottom cavity is internally and slidably provided with a magnetic block, and the iron block and the magnetic block are attracted magnetically.
Preferably, the memory metal sheet comprises a main plate and four auxiliary plates, wherein one of the auxiliary plates is arranged on one side of the main plate, and the other three auxiliary plates are respectively arranged on three sides of the auxiliary plate.
Preferably, the connecting shaft is provided with a hole, and the traction wire penetrates through the hole.
Preferably, the left slider and the right slider are made of high-temperature-resistant anticorrosive rubber, and the lower end of the left movable cavity is communicated with the right movable cavity.
Compared with the prior art, the invention has the beneficial effects that: when the alcohol lamp is toppled, the pulling wire is pulled by utilizing the toppling inclination of the bottle body, the memory metal sheet is extruded out of the cavity through gas, and under the high-temperature action of flame, the memory metal sheet is deformed and folded to cover the flame, so that oxygen is isolated to play a role in extinguishing the fire;
timely effectual flame with the alcohol burner extinguishes, avoids the bottle because roast and breakage, avoids overflowing of alcohol, extinguishes the flame source and can protect the student, guarantees student's experimentation's security, carries out effectual prevention and control to student's abnormal operation.
