In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-6, an alcohol burner capable of automatically extinguishing comprises a bottle body 1 and a fixed plug 2, the fixed plug 2 is clamped at the upper end of the bottle body 1, a cotton thread 3 is arranged in the bottle body 1, one end of the cotton thread 3 passes through the fixed plug 2, the upper surface of the fixed plug 2 is provided with four partition boards 4, the upper surface of the fixed plug 2 is provided with four mounting grooves, each partition board 4 is respectively arranged in the mounting groove, the bottom of the mounting groove is provided with a conductor 5, a cavity is arranged in the conductor 5, a spiral body 10 is arranged in the cavity, one end of the spiral body 10 is fixedly connected with the inner wall of the cavity, a driving rotating shaft 9 is rotatably arranged in the cavity, the other end of the spiral body 10 is fixedly connected with a driving rotating shaft 9, one side of the partition board 4 is inserted with a driven rotating shaft 6, the driven rotating shaft 6 is rotatably arranged in, be connected with haulage rope 7 between four stay cords 8, the material of baffle 4 and conductor 5 is metallic copper, and four baffles 4 are isosceles triangle and each other for congruent triangle, and spirochaeta 10 includes sheetmetal and plastic piece, has seted up between sheetmetal and the plastic piece and has filled the chamber, fills the intracavity and has filled water.

The first embodiment is as follows:

in the invention, when a user uses the device, when the alcohol burner is tilted, the flame at the end of the cotton thread 3 is correspondingly tilted, the flame keeps a vertical upward angle at all times, the flame is directly contacted with the partition plate 4 on the upper surface of the fixed plug 2 due to the tilting of the alcohol burner, the temperature of the alcohol flame is within 400-;

the boiling point of water is 100 ℃, the heat conductivity coefficient of copper is 377W/m DEG C, the volume of the spiral body 10 is smaller, the space between a metal sheet and a plastic sheet in the spiral body 10 is also narrow, the water is heated and quickly vaporized, the volume of the water is increased when the water is changed from a liquid state to a gas state, the gas intermolecular motion is violent in a high-temperature environment, the space of a filling cavity is smaller in a spiral contraction state, when the water is vaporized, the spiral body 10 tends to stretch and straighten, the spiral body 10 drives the driving rotating shaft 9 to rotate in the stretching process, the pulling rope 8 is gradually wound and wound by the rotation of the driving rotating shaft 9, one end of the pulling rope 8 close to the driving rotating shaft 9 is wound, the other end of the corresponding pulling rope 8 is released, the driven rotating shaft 6 drives the partition plate 4 to rotate under the action of the pulling rope 8, the partition plate 4 rotates to stand up the attached figure, the four, the four partition boards 4 are spliced to form a tetrahedron, the tetrahedron covers the end of the cotton thread 3, the end of the cotton thread 3 is placed in a relatively closed space, the alcohol on the cotton thread 3 is combusted to rapidly consume oxygen, and the flame is extinguished after the oxygen in the closed space is consumed, so that the aim and the effect of automatically extinguishing the flame are achieved, and the safety of students is ensured.

Because the toppled alcohol lamp only can have a heating effect on one of the partition plates 4, when the spiral body 10 below the partition plate 4 is heated to pull the pull rope 8, the pull rope 7 can be correspondingly and synchronously pulled, the pull rope 7 is connected with the other pull ropes 8, the pull rope 8 and the pull rope 7 are mutually pulled and linked, the whole body is pulled, the other partition plates 4 can rotate under the traction effect, and the four partition plates 4 are finally combined and spliced into a tetrahedron to cover flames.

When the flame goes out, the temperature of the whole partition plate 4 and the conductor 5 is reduced, the temperature of the spiral body 10 is correspondingly reduced, the vaporized water is liquefied, the internal air pressure is reduced due to the corresponding volume reduction, the spiral body 10 is changed into a contraction state under the action of the air pressure from an extension state, the corresponding spiral body 10 drives the partition plate 4 to rotate reversely through the pull rope 8, the partition plate 4 resets, and the alcohol lamp can be continuously used.

Example two:

the spiral body 10 in the alcohol lamp is made of a memory metal sheet;

when the alcohol burner topples over, flame can with baffle 4 direct contact, and broil baffle 4, baffle 4 receives high temperature and broil the back and can give conductor 5 with heat transfer, the inside cavity of seting up of conductor 5 will also be heated and raised the temperature, the spirochaeta 10 of inside setting will take place deformation under high temperature environment, can change from the contraction state to the extension state, then spirochaeta 10 can drive baffle 4 through stay cord 8 when extending and rotate, each baffle 4 rotates and stands up, and make up and splice into a three-dimensional tetrahedral structure and cover flame, cause the inside oxygen that lacks of tetrahedron, flame goes out then, play the effect that automatic flame extinction guarantees student's safety.

After the flame goes out, the whole alcohol lamp will also be cooled, the temperature of the conductor 5 will also be reduced, the spiral body 10 will restore the deformation and change from the stretching state to the shrinking state, the spiral body 10 pulls the partition plate 4 to rotate and reset through the pull rope 8, and the alcohol lamp can be continuously used.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
