[0020] The present application will be further described in detail below with reference to the embodiments of the drawings.

[0021] For example, Figure 1 and Figure 2As shown, the alcohol stove comprises a sealing cover 4, a fire extinguishing cover 5 and a stove body 1. When not in use, the sealing cover 4 and the fire extinguishing cover 5 are sequentially arranged on the stove body 1. When in use, the sealing cover 4 and the fire extinguishing cover 5 are removed. The fire extinguishing cover 5 can be used to cover the stove body 1 to extinguish the flame. The sealing cover 4 can ensure the evaporation of alcohol cloth in the stove body 1.

[0022] Combining Figure 3 and Figure 4 As shown, the stove body 1 has a cavity for storing alcohol. In the embodiment, the stove body 1 comprises an outer shell 11, a cylindrical inner shell 12 arranged in the middle of the outer shell 11 and a vaporization cylinder 2. The vaporization cylinder 2 is arranged in the inner cavity of the cylindrical inner shell 12 and has an inner concave vaporization ring 22 on the upper end of the outer wall. The outer wall of the vaporization cylinder 2 is provided with a vaporization groove 23 extending upward from the bottom. The upper end of the vaporization groove 23 is in communication with the vaporization ring 22. At least two fire outlet holes 21 are arranged on the inner wall of the upper end of the vaporization cylinder 2 and are in communication with the vaporization ring 22.

[0023] The outer wall of the vaporization cylinder 2 is in close contact with the inner wall of the cylindrical inner shell 12. The vaporization groove 23 is arranged in a spiral shape. The direction of the combustion flame of the fire outlet hole 21 is consistent with the spiral direction of the vaporization groove 23. In this way, the combustion flame of the fire outlet hole 21 is in a spiral shape, which is unique in appearance and the vaporized alcohol is also fully burned. In the embodiment, the vaporization groove 23 and the fire outlet hole 21 are both six and are arranged at intervals.

[0024] The upper end of the outer wall of the vaporization cylinder 2 is formed with a convex ring due to the vaporization ring 22, and the fire outlet hole 21 is arranged on the convex ring. The cylindrical inner shell 12 divides the internal space of the outer shell 11 into a central cavity in the cylindrical inner shell 12 and an outer annular cavity outside the cylindrical inner shell 12. The vaporization cylinder 2 is arranged in the central cavity, and the upper end of the outer annular cavity is provided with a sealing ring 13. The sealing ring 13 has a protruding connecting portion 131 in the middle. The outer thread of the connecting portion 131 can be matched with the inner thread of the sealing cover 4. The upper end of the sealing ring 13 has a horizontal bending portion 132 to limit the position of the cylindrical inner shell 12 and the vaporization cylinder 2.

[0025] When the alcohol is ignited, the vaporized alcohol flows upward along the vaporization groove due to the rapid heating of the alcohol, burns after passing through the vaporization ring and being sprayed from the fire outlet hole, and finally the flame sprayed from the fire outlet hole burns on the central flame of the stove. Due to the capillary effect of the vaporization groove, the pressure of the upward flow of the vaporized alcohol is increased, so that the alcohol is fully burned and the combustion efficiency is improved.
