Of course, the burner 21 can also be entirely the mesh part 212, the mesh part 212 is directly fixed to the net seat 22, and the mesh part 212 is directly fixed to the top plate structure. The fixing mode and the fixing position can be selected by the person skilled in the art according to the needs. The mesh part 212 completely surrounds the ignition disc 211, and when the ignition disc 211 and the mesh part 212 are projected to a plane perpendicular to the horizontal plane, the projection of the ignition disc 211 completely falls into the projection of the mesh part 212. The mesh holes are used for the gas flow inside and outside the burner 21, including the entry of oxygen and the outflow of hot air. In order to clearly show the position of the mesh part 212 in the burner 21 and the specific structure of the mesh hole, in the drawings of the specification in the present application, the diameter of the mesh hole is enlarged from the actual size of 1 mm to 4 mm to the size of 10 to 15 mm, for example, the original mesh hole with a diameter of 2 mm is enlarged to a mesh hole with a diameter of 12 mm, so that the mesh hole is better shown. Of course, the person skilled in the art can select mesh holes with different diameters according to the actual needs.

[0039] The mesh part 212 is provided with a main body part 2121 and a protruding part 2122, the protruding part 2122 protrudes outward from the main body part 2121 along the radial direction of the burner 21 or protrudes inward from the main body part 2121, compared with the burner 21 in the prior art, the setting of the protruding part 2122 increases the heat absorption surface area of the burner 21, increases the radiation area of the burner 21 when radiating to the user, and improves the heating effect of the user. The mesh hole can be located in the main body part 2121, or the mesh hole can be located in the protruding part 2122, of course, one mesh hole can be partially located in the protruding part 2122 and partially located in the main body part 2121. It can be understood that the protruding part 2122 extends away from the main body part 2121.

[0040] The processing procedure of the combustor 21 can utilize a planar sheet metal part to punch a hole, then utilize a stamping structure to punch out the protruding part 2122, then weld the planar head and tail to form a cylindrical combustor 21; or directly utilize an integrated hollow cylindrical sheet metal to punch a hole, then utilize a stamping structure to punch out the protruding part 2122, directly form the combustor 21.

[0041] The formed combustor 21 is cylindrical, the combustor 21 has a central axis, and the distance between each point on the main body part 2121 and the central axis is substantially the same, without considering the thickness of the combustor 21; or in the same vertical plane, the distance between each point on the main body part 2121 and the central axis is substantially the same. The protruding part 2122 includes a peak valley part 21221 and a peak top part 21222, the peak top part 21222 is located at the top of the main body part 2121 protruding outward of the combustor 21 or protruding inward of the combustor 21, and the peak valley part 21221 is located at the connection between the protruding part 2122 and the main body part 2121. The distance between the peak valley part 21221 and the central axis is substantially the same as the distance between the main body part 2121 and the central axis, the distance between the peak valley part 21221 and the central axis is R1, and the distance between the peak top part 21222 and the main body part 2121 is R2. When the protruding part 2122 protrudes outward along the radial direction of the combustor 21 from the main body part 2121, R1 is less than R2; when the protruding part 2122 protrudes inward along the radial direction of the combustor 21 from the main body part 2121, R1 is greater than R2.

[0042] Please refer to Figure 5 and Figure 7 As shown, the protruding part 2122 in the embodiment is a long strip in the height direction. Specifically, please continue to refer to Figure 5 As shown, after the combustor 21 is formed, the length direction of the protruding part 2122 is the height direction of the combustor 21; please refer to Figure 9 As shown, the length direction of the protruding part 2122 is the height direction of the combustor 21 after being unfolded. The protruding part 2122 extending in the height direction has the effect of strengthening the combustor 21, improves the strength of the combustor 21, and reduces the possibility of the combustor 21 collapsing due to high temperature creep.

[0043] The convex portion 2122 is multiple, and the convex portions 2122 are arranged left and right. The burner 21 or the mesh portion 212 has an inner surface and an outer surface, and the inner surface of the burner 21 is closer to the ignition disc 211 than the outer surface. When the burner 21 is working, the flame near the ignition disc 211 heats the main body portion 2121 and the convex portion 2122 from the inside of the burner 21, that is, the flame first heats the inner surface of the burner 21, and then the heat is partially transferred to the outer surface through the thermal conduction of the material of the burner 21 itself, partially directly heats the outer surface through the hot gas flow, and partially heats the outer surface through the flame overflowing from the hole. When the convex portion 2122 protrudes from the main body portion 2121 in the radial direction of the burner 21 towards the outside of the burner 21, compared with the burner 21 in the prior art, the flame or the hot gas flow overflowing from the mesh of the convex portion 2122 gathers on the outer surface of the main body portion 2121 between two adjacent convex portions 2122, so that the hot gas flow heats the outer surface of the main body portion 2121 again. The hot gas flow stays on the outer surface of the main body portion 2121 for a long time due to the turbulence of the gas flow, which improves the heating time and temperature of the main body portion 2121, improves the temperature of the main body portion 2121, and thus improves the heat radiation intensity of the main body portion 2121 and the heating effect of the heater. When the convex portion 2122 protrudes from the main body portion 2121 in the radial direction of the burner 21 towards the inside of the burner 21, compared with the burner 21 in the prior art, the flame or the hot gas flow overflowing from the mesh of the convex portion 2122 gathers in the inside of the convex portion 2122. Due to the mutual interference of the hot gas flow, the residence time of the hot gas flow in the inside of the convex portion 2122 is improved, and thus the heating time and the surface temperature of the convex portion 2122 are improved, and the heat utilization rate and the heat radiation effect of the burner 21 are improved. It can be understood that part of the convex portion 2122 protrudes from the main body portion 2121 towards one side of the inner surface, and part of the convex portion 2122 protrudes from the main body portion 2121 towards one side of the inner surface. Alternatively, the convex portion 2122 protrudes from the main body portion 2121 towards one side of the inner surface alone. Alternatively, the convex portion 2122 protrudes from the main body portion 2121 towards one side of the outer surface alone. The multiple convex portions 2122 surround the

[0044] The main body portion 2121 of the burner 21 is located on the side surface of the burner 21. Within the process error range, the side surface of the burner 21 is the side surface of a cylinder. The mesh of the convex portion 2122 is projected towards the curved surface where the side surface of the burner 21 is located, and the mesh of the main body portion 2121 is projected towards the curved surface where the side surface of the burner 21 is located. The projection area of the mesh of the convex portion 2122 is smaller than the projection area of the mesh of the main body portion 2121, so that the mesh of the convex portion 2122 is less affected by the wind, and the wind resistance of the burner 21 is improved.

[0045] Please continue to participate Figure 1 and Figure 5 As shown in the drawings,Figure 5 The burner 21 with the protruding part 2122 has the following advantages compared with the burner 21 in the prior art: Figure 1

[0046] 1. The protruding part 2122 is arranged so that the area of the mesh part 212 is larger, the burner 21 absorbs more heat from the flame near the ignition tray 211, and the heat absorption effect of the burner 21 is improved;

[0047] 2. Since the area of the flame absorbed by the burner 21 is larger, the area of the heat radiation of the burner 21 is larger, the heat radiation effect of the burner 21 is improved, and the heating effect of the heater is improved;

[0048] 3. The protruding part 2122 has a reinforcing effect in the height direction of the burner 21, improves the pressure-bearing capacity of the burner 21 in the height direction, and further improves the structural strength of the burner 21;

[0049] 4. The mesh part located at the protruding part 2122 has stronger wind resistance, and the outdoor wind resistance effect of the burner 21 is improved.

[0050] In other embodiments, please refer to Figures 10 to 12 As shown in the figure, after the burner 21 is formed, the protruding part 2122 is a long strip shape along the circumferential direction of the side wall of the burner 21; after the burner 21 is unfolded, the protruding part 2122 is a long strip shape along the length direction of the burner 21.

[0051] The protruding part 2122 protrudes from the main body part 2121 along the radial direction of the burner 21 towards the outside of the burner 21 or towards the inside of the burner 21. In this embodiment, the protruding part 2122 protrudes from the main body part 2121 along the radial direction of the burner 21 towards the outside of the burner 21.

[0052] There are multiple protruding parts 2122, and the protruding parts 2122 are arranged above and below. In addition to the heating mode of the outer surface of the burner 21 being the same as that of the burner 21 in the prior art, the outer surface of the burner 21 in this embodiment also has a mesh part located below the protruding part 2122. The hot gas flow overflowing from the inside of the burner 21 flows upwards along the outer surface of the burner 21, and when the hot gas flow meets the protruding part 2122, the flow path of the hot gas flow is improved, thereby improving the contact time of the hot gas flow with the outer surface of the burner 21, i.e. improving the heat exchange time of the hot gas flow with the burner 21, improving the temperature of the outer surface of the burner 21, and improving the heat radiation effect and heating effect of the burner 21.

[0053] The protruding part 2122 is more likely to be located at the outer flame of the flame near the ignition tray 211 compared with the main body part 2121, which improves the temperature of the flame heating the burner 21, thereby improving the radiation effect of the burner 21.​

[0054] In some other embodiments, the burner 21 with the protrusion 2122 has at least 5% more surface area than the burner 21 of the prior art, such as 5% to 50% more surface area, and more particularly, 18% to 22% more surface area, such as 20% more surface area. Figure 13 and Figure 14 As shown, the protrusion 2122 is in a hemispherical or quarter-spherical structure. This structure combines the advantages of the protrusion 2122 being long in the height direction and long in the circumferential direction, and the embodiments are not repeated here.
