The present invention is further illustrated by way of the following examples, which are not intended to limit the scope of the invention.

As shown in fig. 1-6, the preferred embodiment of the present invention provides a torch 100, which comprises a housing 7, a torch inner flame structure 200 inside the housing 7, a torch main flame structure 300, a gas tank 5, and a gas channel 4 for delivering gas in the gas tank 5 to the torch inner flame structure 200 and the torch main flame structure 300. In this embodiment, the torch inner flame structure 200 is disposed below the main torch flame structure 300, and the inner flame generated by the inner flame structure is located inside the outer shell 7, and can be continuously burned in severe weather such as strong wind, heavy rain, and snow, thereby preserving the flame. When the main flame is extinguished due to strong wind or rain, the inner flame generated by the torch inner flame structure 200 can quickly reignite the main flame, so that the torch 100 has the capability of continuous combustion in various weather conditions.

As shown in fig. 1 to 6, in the present embodiment, the flare 100 includes, in addition to the gas channel 4, a flare gas supply structure located below the gas channel 4 for supplying gas into the gas channel 4. The torch gas supply structure further comprises a gas nozzle 6, the gas nozzle 6 is arranged towards the inlet end of the gas channel 4, and the gas nozzle 6 is communicated to the gas tank 5 at the lowest part of the torch. The gas channel 4 is arranged along the vertical direction, the outlet end of the upper part is divided into three gas distributing pipes 202 and then connected with a fire outlet 201 to jointly form a torch inner flame structure 200, and the inlet end of the lower part is an inlet of gas and air and is connected with the gas nozzle 6. A gap is arranged between the gas nozzle 6 and the inlet end of the gas channel 4, and when gas enters the gas channel 4 through the gas nozzle 6, the gap can suck outside air into the gas channel 4 by utilizing negative pressure to form the mixing of the gas and the air, thereby being beneficial to enhancing the combustion of inner flame.

As shown in fig. 1-6, the flame structure 200 in the torch provided by the preferred embodiment of the present invention has a flame outlet except for the gas channel 4, wherein the number of the flame outlet 201 is at least three, all the flame outlet 201 are independently arranged, and are respectively arranged in different directions, the flame outlet 201 is communicated to the gas source through the gas channel 4, and the flame generated by the gas at all the flame outlet 201 jointly forms the flame in the torch. 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.

As shown in fig. 1 to 6, in this embodiment, in order to facilitate ignition of the main flame above the inner flame structure and avoid rain water from interfering with the inner flame, all the fire outlets 201 are inclined upward at the same reasonable inclination angle and extend outward with the gas channel 4 as the center, wherein the preferred range of the inclination angle is 25 ° to 65 °, and according to tests and theoretical calculation, the above-mentioned structure arrangement mode has the best adaptation effect compared with various common main flame structures.

As shown in fig. 1 to 6, in the present embodiment, the projection of the direction of the fire outlets 201 on the plane of the circular ring is curved toward the tangent of the circular ring at the fire outlets 201, preferably, all the fire outlets 201 are oriented in the same clockwise direction, and the fire outlets 201 are arranged at equal angular intervals with the gas channel 4 as the center.

The embodiment also provides another preferable structure form, namely a turning structure similar to an elbow is arranged at the front end of the fire outlet 201, so that the gas flow deviates to the tangential direction of the circular ring, the gas can form vortex in the same clockwise direction, the flame is also prevented from being directly irradiated to the inner side of the flare shell 7, a more concentrated inner flame is formed, and the probability of reburning the main flame is improved. It should be noted that the structural form of the above-mentioned solution is not limited to the elbow at the fire outlet 201, and the structure of the fire outlet 201 and the gas distribution pipe 202 may be combined to form a spiral shape, so as to obtain a gas flow vortex, so as to achieve the same effect.

As shown in fig. 1 to 6, the torch inner flame structure 200 in this embodiment further includes a plurality of gas distribution pipes 202 for connecting the fire outlets 201 and the gas channels 4, the gas distribution pipes 202 and the fire outlets 201 are arranged in a one-to-one correspondence, and all the gas distribution pipes 202 are butted to the gas channels 4 at the same position. In this embodiment, a flow guiding structure is further disposed at the position, and the flow guiding structure has an arc-shaped flow guiding surface, so that the gas flow smoothly and uniformly enters the gas distribution pipe 202.

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.
