All the fire outlets 201 are distributed on a plane at the same height and are arranged obliquely upward at the same inclination angle with respect to the plane. In this embodiment, the fire outlets 201 are distributed on a ring using the channel axis of the gas channel 4 as the center, and the fire outlets 201 extend outward using the gas channel 4 as the center.
Specifically, in the present embodiment, three fire outlets 201 facing different directions are provided. Thus, when strong wind blows to the inner flame structure 200, at least one direction of the fire outlets 201 can be not affected, even if the wind force blows off part of the flame of the fire outlets 201, the fire species can still be remained, and the main flame can be continuously reburned.
Further, in order to facilitate ignition of the main flame, all the fire outlets 201 are disposed on a plane at the same height and are arranged in a circular ring shape. Through the arrangement, the inner flames have the same or similar heating effect in all directions, and the phenomenon that the main flame cannot be independently ignited when a certain fire outlet 201 of the inner flames is not extinguished is avoided. It should be understood by those skilled in the art that the provision of three fire outlets 201 in the present embodiment does not represent that three are the optimal solutions of the present embodiment, and the same effect can be achieved by similarly arranging a plurality of fire outlets 201.

Specifically, since the flame outlet 201 in the present embodiment is a structure rotationally symmetric with respect to the center of the gas passage 4, if the gas flow is unevenly distributed, the rotationally symmetric structure cannot be fully utilized. Therefore, a flow guiding structure is additionally arranged at the position where the gas channel 4 leads to each fire outlet 201, and the gas is uniformly guided to the gas distributing pipe 202 through the flow guiding surface, so that the gas obtained by each fire outlet 201 is approximately equal, and the whole inner flame is more stable and uniform.
As shown in fig. 1-6, in the present embodiment, the main flame structure 300 of the torch includes a gas pipe 301 connected to the gas tank 5, the end of the gas pipe 301 surrounds along a horizontal plane to form a fire ring, the fire ring has a plurality of fire holes 302 uniformly distributed thereon, the fire holes 302 are disposed obliquely upward and toward the inner side of the fire ring, and the axes of the fire holes 302 intersect at a point above the fire ring on the central axis. The distance from the axis intersection point of the fire holes 302 to the center of the fire ring is less than or equal to the radius of the fire ring.
Specifically, in this embodiment, one end of the gas pipe 301 is connected to the gas tank 5, and the other end is bent to form a fire ring, the plane of the fire ring is set according to the flame shape requirement of the torch, and the plane of the fire ring is a horizontal plane in this embodiment. The part on the inner side of the fire ring is provided with fire holes 302, and the axes of all the fire holes 302 are intersected at a point above the fire ring and on the central axis. Correspondingly, the gas flows formed by the gas ejected from the fire holes 302 will converge at this point, resulting in the largest inflow of gas at this point; and because the velocities of all the gas flows in the horizontal direction will cancel each other out, the outflow velocity of the gas at this point is minimal. When the gas is ignited, the fullest flame will be formed at this point because the gas input is the greatest and the exit velocity is the least at this point.
According to the principle of velocity decomposition, if the angle between the axis of the fire hole 302 and the plane of the fire ring is 45 °, the components of the velocity of the gas flow in the horizontal direction and the vertical direction should be approximately equal. At this time, after the horizontal components of the gas flow velocity are offset, the components in the vertical direction are converged and the velocity of the gas flow itself should be approximately equal. In order to achieve a better self-deceleration effect, in the present embodiment, an included angle between the axis of the fire hole 302 and the plane of the fire ring is set to be 45 ° or less, that is, from a geometric relationship, a distance from the intersection point of the axes of the fire holes 302 to the center of the fire ring is equal to or less than a radius of the fire ring. Through the structure, all the gas flows form slowly-rising total gas flow after being converged, and full and stable flame can be formed after ignition.
In this embodiment, the main flame structure 300 and the inner flame structure 200 are matched, so that the fire outlet 201 of one inner flame structure 200 corresponds to a group of fire hole groups consisting of a plurality of fire holes 302, and the main flame can be reburned by the inner flame in all directions around the circumference. And then the inner flame and the main flame can have better response capability to the interference of different angles, and even if the inner flame and/or the main flame in a certain direction is accidentally extinguished, the whole inner flame cannot be completely extinguished, and the reburning probability of the main flame can be obviously improved.
Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
