[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1 Combination Figures 1-5 The alcohol furnace in this embodiment includes: a furnace body 1, a protective cover 3, a fire extinguishing plate 4, and several first clamps 2. The furnace body 1 is used to hold alcohol, and its top surface has a fire outlet 121. Several first clamps 2 are distributed around the fire outlet 121 around the furnace body 1. One end of the fire extinguishing plate 4 is a fire extinguishing end 41, and the other end is a handheld end 42. The handheld end 42 is used to insert the fire extinguishing end 41 into the protective cover 3 from the side through the first gap 8 and cover the fire outlet 121 of the furnace body 1 to extinguish the fire. It can be understood that the length of the fire extinguishing plate 4 can be designed according to actual needs, but at least it must be ensured that when the fire extinguishing end 41 of the fire extinguishing plate 4 covers the fire outlet 121, its handheld end 42 has a margin extending out of the protective cover 3 for the operator to hold.

[0034] In the fire extinguishing process of the alcohol stove in this embodiment, the operator's hands can maintain a safe distance from the flames, effectively avoiding the risk of burns from the flames, and the fire extinguishing is also faster and more stable.

[0035] The first clamp 2 in this embodiment includes a first support pad 21 and a first tightening bolt 22. The first support pad 21 is connected to the top surface of the furnace body 1. The top of the first support pad 21 has an upward-facing first opening groove 211, and a first threaded hole 212 is formed on the outside of the first opening groove 211. The first tightening bolt 22 is threaded into the first threaded hole 212. The bottom of the protective cover 3 is inserted into the first opening groove 211, forming a first gap 8 between it and the furnace body 1. The end of the first tightening bolt 22 laterally abuts against the protective cover 3.

[0036] In this embodiment, the protective cover 3 and the first support pad 21 are fastened by the lateral clamping force provided by the first clamping bolt 22. This can prevent the protective cover 3 from falling off due to vibration or external impact during the use of the alcohol furnace. At the same time, this structure allows the protective cover 3 to be disassembled separately without damaging the structure of the alcohol furnace. This not only meets the modular requirements of production assembly, but also provides convenience for later cleaning and maintenance.

[0037] In this embodiment, a screw 213 is provided at the bottom of the first support pad 21, and a corresponding through hole is opened at the top of the furnace body 1. After inserting the screw 213 into the through hole from top to bottom, the nut 214 is screwed on, thereby locking the first support pad 21 onto the top surface of the furnace body 1. In some other embodiments of this utility model, the first support pad 21 can also be welded to the top surface of the furnace body 1, or can be detachably connected to the top surface of the furnace body 1 by bolts. That is, a threaded hole is opened at the bottom of the first support pad 21, and a corresponding through hole is opened at the top of the furnace body 1. The bolt is inserted into the through hole from bottom to top and screwed into the threaded hole, thereby locking the first support pad 21 onto the top surface of the furnace body 1.

[0038] The protective cover 3 in this embodiment is preferably made of high-temperature resistant glass, and the transparency and color of the glass can be designed according to actual needs. The shape of the protective cover 3 can be designed according to actual needs, such as cylindrical, elliptical cylindrical, triangular prism, square prism, pentagonal prism, etc.

[0039] The furnace body 1 in this embodiment includes a furnace cylinder 11, a cover plate 12, an isolation mesh cylinder 13, a partition plate 14, a plug, and steel wool (not shown in the figure). The furnace cylinder 11 is hollow inside and open at the top. The cover plate 12 is connected to the top of the furnace cylinder 11, and the isolation mesh cylinder 13 is connected between the cover plate 12 and the furnace cylinder 11, dividing the inner cavity of the furnace cylinder 11 into a combustion chamber 15 located in the middle and an alcohol storage chamber 16 surrounding the combustion chamber 15. The cover plate 12 has a flame outlet 121 located inside the isolation mesh cylinder 13 and a filling port 122 communicating with the alcohol storage chamber 16. The partition plate 14 is connected inside the isolation mesh cylinder 13, dividing the isolation mesh cylinder 13 into upper and lower layers. The partition plate 14 has a plurality of flame outlet holes 141. By designing the shape of the flame outlet holes 141, the burning flame can present a specific shape. At this time, the alcohol level cannot exceed the partition plate 14. For example, in this embodiment, the flame outlet holes 141 on the partition plate 14 form a snowflake shape, so that the ejected flame presents a snowflake shape. The plug is installed inside the filling port 122, providing a certain degree of protection. To add alcohol through the filling port 122, the flame must be extinguished first, and the plug removed before adding the liquid. This prevents the user from adding liquid while the flame is burning, thus avoiding a safety hazard. Steel wool is placed inside the alcohol storage chamber 16 to prevent the alcohol within the chamber from burning. It is understood that the furnace body 1 of this invention can also use other existing furnace body structures, such as a hollow structure with a flame outlet 121 on the top surface.

[0040] Understandably, during ignition, the ignition gun can be inserted either from the top of the protective cover 3 or from the side of the first gap 8. The first gap 8 not only facilitates ignition and extinguishing operations but also allows air to enter from the bottom of the protective cover 3, providing sufficient air for alcohol combustion and thus improving combustion efficiency.

[0041] Example 2 Combination Figures 6-9 Compared with Embodiment 1, the main difference in this embodiment is that it also includes a protective cover 6 and several second clamps 5. The protective cover 6 is connected to several second clamps 5 distributed circumferentially along its periphery. The protective cover 6 is mounted on the top of the protective cover 3 via these second clamps 5, forming a second gap 9 between it and the protective cover 3. The protective cover 6 further enhances the safety of the alcohol furnace, preventing flames from escaping from the protective cover 3. The second gap 9 provides sufficient air for alcohol combustion.

[0042] The second clamp 5 in this embodiment includes a second support pad 51, a second clamping bolt 52, and a third clamping bolt 53. The bottom of the second support pad 51 has a downward-facing second opening groove 511, and a second threaded hole 512 is formed on the outer side of the second opening groove 511. The second clamping bolt 52 is threaded into the second threaded hole 512. The top of the protective cover 3 is inserted into the second opening groove 511, and the end of the second clamping bolt 52 laterally abuts against the protective cover 3. The top of the second support pad 51 has an inward-facing third opening groove 513, and a third threaded hole 514 is formed above the third opening groove 513. The third clamping bolt 53 is threaded into the third threaded hole 514, and the protective cover 6 is laterally inserted into the third opening groove 513. The third clamping bolt 53 presses downward against the protective cover 6.

[0043] The second clamp 5 provides lateral clamping force through the second clamping bolt 52 to achieve a tight connection between the protective cover 3 and the second support pad 51. This can prevent the protective cover 6 from falling off due to vibration or external impact during use. At the same time, this structure allows the protective cover 6 to be disassembled separately without damaging the structure of the alcohol furnace. It not only meets the modular requirements of production assembly, but also provides convenience for later cleaning and maintenance, and enriches the diversity and flexibility of the use of the alcohol furnace.

[0044] The second clamp 5 provides vertical clamping force through the third clamping bolt 53 to achieve a tight connection between the protective cover 6 and the second support pad 51, and also achieves a holeless connection of the protective cover 6.

[0045] The protective cover 6 is preferably made of high-temperature resistant glass, and its transparency and color can be designed according to actual needs. The shape of the protective cover 6 corresponds to that of the protective shield 3, such as circular, oval, triangular, quadrilateral, pentagonal, etc.

[0046] Example 3 Combination Figure 10 and Figure 11 The main difference between this embodiment and Embodiment 1 and Embodiment 2 is that the end of the first tightening bolt 22 is connected to a first anti-slip pad 23 that abuts against the first tightening bolt 22 and the protective cover 3, the end of the second tightening bolt 52 is connected to a second anti-slip pad 54 that abuts against the second tightening bolt 52 and the protective cover 3, and the end of the third tightening bolt 53 is connected to a third anti-slip pad 55 that abuts against the third tightening bolt 53 and the protective cover 6.

[0047] The first anti-slip pad 23, the second anti-slip pad 54, and the third anti-slip pad 55 can increase friction, improve the sealing effect, increase the connection strength, and prevent scratches on the protective cover 3 and the protective cap 6.

[0048] Example 4 Combination Figure 12The main difference between this embodiment and Embodiments 1 and 2 is that the outer surface of the protective cover 3 has an annular first limiting groove 31, and the end of the first tightening bolt 22 is inserted into the first limiting groove 31. The outer surface of the protective cover 3 has an annular second limiting groove 32, and the end of the second tightening bolt 52 is inserted into the second limiting groove 32. The top surface of the protective cover 6 has an annular third limiting groove 61, and the end of the third tightening bolt 53 is inserted into the third limiting groove 61.

[0049] The limiting groove and the tightening bolt are engaged to play a certain limiting role, which can effectively prevent the protective cover 3 / protective cover 6 from falling off, and make it easier to hold the protective cover 3 or protective cover 6 to take the alcohol stove.

[0050] The annular limiting groove allows the clamping bolt to be inserted from any point, making assembly easier. It is understandable that, in addition to being annular, the limiting groove can also be non-annular, depending on the positions of the first clamps 2 and the second clamps 5, with corresponding positions on the protective cover 3 and the protective cap 6. For example, several first limiting grooves 31 corresponding to the first clamps 2 can be opened on the outer side of the protective cover 3, with the end of the first clamping bolt 22 inserted into the corresponding first limiting groove 31; several second limiting grooves 32 corresponding to the second clamps 5 can be opened on the outer side of the protective cover 3, with the end of the second clamping bolt 52 inserted into the corresponding second limiting groove 32; and several third limiting grooves 61 corresponding to the second clamps 5 can be opened on the top surface of the protective cap 6, with the end of the third clamping bolt 53 inserted into the corresponding third limiting groove 61.

[0051] Example 5 Combination Figure 13 In order to eliminate the safety hazards caused by alcohol leakage, this embodiment also includes a leak-proof bottom box 7, and the furnace body 1 is inserted into the leak-proof bottom box 7.
