The existing air guide groove stove is built into the stove body. Although the stove body produces a certain heat insulation effect, the stove needs to be used on a flat surface. When the stove is used for outdoor camping, there are often weeds or fallen leaves on the ground. The bottom surface of the stove body is easily blocked, affecting the air intake effect of the air guide groove, and when used on a thick plush carpet, it is also easy to affect the air intake effect of the stove body. Utility Model Content

[0003] Therefore, in response to the above problems, the present invention proposes a high-temperature resistant rotating flame alcohol stove, which solves the technical problem that the air guide groove of the existing stove body is placed on the bottom surface, and the stove body is easily blocked on the bottom surface, affecting the air intake effect of the air guide groove.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a high-temperature resistant rotating flame alcohol stove, comprising a base, a cylinder provided on the top of the base and used to place alcohol fuel, a spiral protrusion provided on the outside of the cylinder, an enclosing cover sleeved on the outside of the spiral protrusion, and support columns provided on the top surface of the base and used to keep the enclosing cover spaced apart from the base, the top surface of the support columns being in contact with the bottom surface of the enclosing cover, and gaps leading to the space between the enclosing cover and the spiral protrusions being provided between the support columns.

[0005] Furthermore, the surrounding cover is made of transparent glass.

[0006] Furthermore, a fireproof pad is adhered to the top surface of the support column.

[0007] Furthermore, the base is provided with a downwardly sunken portion in the middle of the support column, and the recess has a smooth transition with the plane of the base.

[0008] Furthermore, there are three spiral protrusions.

[0009] Furthermore, there are three or more support columns, and the width of the support columns is 4 to 40 mm.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are:

[0011] The high-temperature resistant rotating flame alcohol stove is provided with a cylinder on the top of the base, wherein the combustion material is placed in the cylinder, and the combustion material will be placed above the base. After completion, the enclosing cover is placed to block the outside of the spiral protrusion. The bottom of the enclosing cover will be separated from the base to form a gap leading to the spiral protrusion. The combustion material is then ignited, and oxygen enters from the gap between the support columns, and then leads to the gap between the cylinder and the spiral protrusion to form a spiral airflow, which is then blown into the enclosing cover. At the same time, due to the chimney effect, the air is quickly diffused or discharged from the enclosing cover due to the effect of density difference. Under the action of the inhaled spiral airflow, the flame in the enclosing cover will be in a rotating upward shape. The cylinder for placing the fuel material is placed above the top of the base, and the air inlet of the spiral protrusion is between the enclosing cover and the base. When placed on the ground for use, it will not be blocked. Compared with the existing stove body where the air guide groove is placed on the bottom surface, the ventilation effect is better, and the technical problem that the existing stove body air guide groove is placed on the bottom surface, the stove body is easily blocked on the bottom surface, which affects the air intake effect of the air guide groove is solved.

[0016] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0017] refer to Figures 1 to 4 The present embodiment provides a high-temperature resistant rotating flame alcohol stove, comprising a base 1, a cylinder 2 provided on the top of the base 1 and used to place alcohol fuel, a spiral protrusion 3 provided on the outside of the cylinder 2, a surrounding cover 4 sleeved on the outside of the spiral protrusion 3, and support columns 5 provided on the top surface of the base 1 and used to keep the surrounding cover 4 and the base 1 spaced apart. The top surface of the support columns 5 contacts the bottom surface of the surrounding cover 4, and a gap 6 is provided between the support columns 5 to lead to the space between the surrounding cover 4 and the spiral protrusion 3. Figure 3 , the gap 6 is the dotted line position in the figure, that is, the gap 6 between the support columns 5.

[0018] During use, the combustion material is first placed in the cylinder 2. After completion, the enclosing cover 4 is placed to block the outer side of the spiral protrusion 3. The bottom of the enclosing cover 4 will be separated from the base 1 to form a gap 6 leading to the spiral protrusion 3. Then the combustion material is ignited, and oxygen will enter from the gap 6 between the support columns 5, and then lead to the gap between the cylinder 2 and the spiral protrusion 3 to form a spiral airflow, and then blown into the enclosing cover 4. At the same time, due to the chimney effect, the air quickly diffuses or is discharged from the enclosing cover 4 due to the density difference. Under the action of the inhaled spiral airflow, the flame in the enclosing cover 4 will be in a rotating upward shape, which is more beautiful than the existing ordinary stoves. The material in the cylinder 2 burns more completely, and the flame in the enclosure 4 is less likely to be extinguished, making it safer to use. The cylinder 2 for placing fuel materials is placed above the top of the base 1, and the air inlet of the spiral protrusion 3 is between the enclosure 4 and the base 1. When placed on the ground for use, it will not be blocked. Compared with the existing stove body with the air guide groove placed on the bottom surface, the ventilation effect is better. Some existing stoves will make the spiral blades into inclined oblique plates and place them horizontally on the entrance enclosure 4 or base 1, but the inclined oblique plate type air inlet is difficult to process, and since it is necessary to open holes on the base, cylinder or enclosure, it affects the aesthetics and strength, and has a great impact on the service life and appearance of the product.

[0019] The enclosure 4 is made of transparent glass, and can also be replaced by fireproof ceramics, fireproof plastics or other fireproof materials. Transparent fireproof materials are the best use scenario. The materials are all existing technologies and will not be described in detail here.

[0020] The top surface of the support column 5 is adhered with a fireproof pad 7, which can increase the top pressure height of the support column 5 and prevent the surrounding cover 4 from being directly in contact with the support column 5 due to strong force and causing bumps and cracks when the surrounding cover 4 is made of glass.

[0021] The base 1 is provided with a downwardly concave recess 101 in the middle of the support column 5. The recess 101 has a smooth transition with the plane of the base 1. The recess 101 can increase the spacing height between the enclosure 4 and the top surface of the base 1, increase the amount of airflow entering, and increase the distance from the spiral protrusion 3, making it more convenient for manual cleaning.

[0022] There are three spiral protrusions 3, and the number of spiral protrusions 3 can be customized according to actual usage. However, if the number is too small, the cyclone-forming effect of the flow guidance is not strong. If the number is large, the spacing between the spiral protrusions 3 is reduced, which affects the air intake volume. The optimal number is two to four. During actual use, the number can be increased or decreased according to the diameter of the cylinder 2, and is not limited to the three spiral protrusions 3 in the drawings of the specification.

[0023] There are more than three support columns 5, and the width of the support columns 5 is 4 to 40 mm. If the number of support columns 5 is too large or the width is larger, it will also affect the amount of air entering. 4 to 40 mm has little effect on the amount of air entering. During actual use, it can be adjusted according to the diameter of the cylinder 2. If the diameter of the cylinder 2 is large, it can also exceed the range of 4 to 40 mm.

[0024] The support column 5 is provided with a slot 501 for the enclosure 4 to be snapped into, and a top column 502 for passing through the slot is provided on one side of the support column 5. A limit block 503 is fixed to the outside of the top column, and a compression spring 504 is provided between the limit block and the top column. A silicone head 505 is provided on the side of the top column close to the enclosure. When in use, the enclosure is first snapped into the slot, and one side of the silicone head will be clamped to the bottom of the enclosure under the action of the compression spring, making it less likely to fall off, and avoiding the problem of the enclosure rolling off the desktop when the base tilts over.
