[0030] The first column hole 11 is connected to the second column hole 21, and the first convex hole 12 is intermittently connected to the second convex hole 22;

[0031] The nozzle 2 is provided with a plurality of rows of holes 25 intermittently connected to the first convex holes 12 .

[0032] Specifically, the flame spray base 1 and the nozzle 2 body are prior art and are not described in detail here. The flame spray base 1 is provided with a gas injection port, and the nozzle 2 exhaust port is provided with an ignition plate.

[0033] By rotating the nozzle 2 on the flame-spraying base 1, the area of ​​the hole on the nozzle 2 connected with the hole on the flame-spraying base 1 can be changed intermittently, and when the first column hole 11 and the second column hole 21 are kept connected, the gas sprayed from the nozzle 2 is kept at the fastest rate, so that the flame is in a slender state; when the first convex hole 12 is connected to the second convex hole 22, the cross-sectional area of ​​the exhaust hole is kept medium, and the gas spraying rate is medium at this time, so that the flame is in a medium thick and long state; when the multiple rows of holes 25 are connected to the first convex hole 12, the gas is branched again at this time, and the gas sprayed from the nozzle 2 is kept at the slowest rate, so that the flame is in the thickest and shortest state, and at this time, the multiple rows of holes 25 and the second column hole 21 and the second convex hole 22 synchronously spray flames, so that the flame on the nozzle 2 is in a flower shape, so that the flame on the performance boat can be performed in a variety of different performance changes, increase the performance effect, and improve the audience's viewing experience.

[0034] As an embodiment further provided by the present invention, the nozzle 2 is provided with a connecting hole 23 and a ring hole 24, and a plurality of rows of holes 25 are connected to the ring hole 24;

[0035] The docking hole 23 is intermittently matched with the first convex hole 12 .

[0036] Specifically, the end of the docking hole 23 is intermittently connected to the first convex hole 12 (eg Figure 3 and Figure 4 shown).

[0037] During the rotation of the nozzle 2, the docking hole 23 and the first convex hole 12 are connected, so that the first column hole 11 can replenish part of the gas into the annular hole 24, and the gas is further replenished into the plurality of row holes 25, so that the row holes 25 cooperate with the second column hole 21 to spray flower-shaped flames.

[0038] As another embodiment further provided by the present invention, a plurality of support blocks are fixedly mounted on the nozzle 2, and a wind shield 3 located outside the nozzle 2 is fixedly mounted on the support block.

[0039] Specifically, the wind shield 3 is a stainless steel metal shield, and the support block leaves an air suction gap between the wind shield 3 and the nozzle 2 .

[0040] When the nozzle 2 is working, the wind shield 3 shields and protects the flame, thereby preventing the flame from being disturbed by wind.

[0041] As another embodiment further provided by the present invention, the wind shield 3 cooperates with the flamethrower base 1 and the nozzle 2 in sequence to form a connected air intake duct 31 and an exhaust duct 32.

[0042] Specifically, the rapidly ejected flame allows external air to enter from the bottom of the wind shield 3 and flow to the position of the nozzle 2 (such as Figure 5 shown).

[0043] The air enters the wind shield 3 from the lower port of the air intake duct 31, so that the gas can flow to the exhaust duct 32 through the gap between the support blocks, so that the upwardly blown gas can reduce the dust in the outside world from drifting onto the nozzle 2, and increase the safety and stability of the nozzle 2 when working.

[0044] As another embodiment further provided by the present invention, an air intake hole 13 connected to the first column hole 11 is provided on the flame spray base 1 , and the air intake hole 13 cooperates with the air intake duct 31 .

[0045] The air entering the air intake duct 31 flows to the air intake hole 13, so that the air intake hole 13 draws air into the first column hole 11, so that more oxygen is added to the fuel gas during the flow process, which facilitates the rapid combustion of the fuel gas. At the same time, it also increases the oxygen demand of the nozzle 2 when spraying with different flames, thereby increasing the flame spraying effect.

[0046] As another embodiment further provided by the present invention, an elastic membrane flap is provided at the end of the air suction hole 13 .

[0047] Specifically, the elastic membrane flap is a rubber membrane flap, and the elastic membrane flap is similar to a one-way valve, which transports air in one direction. This is a prior art and will not be described in detail here.

[0048] The elastic membrane flap is provided to ensure that the air intake hole 13 maintains a unidirectional flow when inhaling air, thereby avoiding gas leakage, increasing the oxygen delivery effect, and improving the flame combustion effect.

[0049] As another embodiment further provided by the present invention, a plurality of rows of holes 25 cooperate with the exhaust duct 32 .

[0050] By having the air entering the exhaust duct 32 at the positions of the plurality of row holes 25, the oxygen in this air can supplement the flame combustion, thereby avoiding oxygen deficiency during the process of the wind shield 3 shielding the row holes 25 and increasing the flame combustion efficiency and stability.

[0051] As another embodiment further provided by the present invention, a motor is arranged on the flame spraying base 1, a gear is arranged at the output end of the motor, and an inner ring gear meshing with the gear is arranged at the bottom of the spray head 2.

[0052] Specifically, the motor is fixedly installed in a protective cover installed on the side of the flamethrower base 1, the output end of the motor is connected to the shaft using a coupling, the gear is fixedly installed on the end of the shaft, and the motor is existing technology and will not be described here; an annular notch is opened at the bottom of the nozzle 2, and the inner ring gear is fixedly installed in the notch.

[0053] The motor drives the gear to rotate through the shaft, so that the gear meshes with the inner ring gear to drive the nozzle 2 to rotate, which facilitates the intermittent airway connection between the nozzle 2 and the flame-spraying base 1. The operation is convenient and the use performance is efficient, so that the airway can be quickly connected, and a seal is provided between the nozzle 2 and the flame-spraying base 1 to avoid gas leakage in the airway.

[0054] Working principle: The motor drives the gear to rotate through the shaft, so that the gear meshes with the inner ring gear to drive the nozzle 2 to rotate, and the nozzle 2 rotates on the flame-spraying base 1, so that the channel on the nozzle 2 can intermittently change the area of ​​the channel connection with the channel on the flame-spraying base 1, and when the first column hole 11 and the second column hole 21 are kept in communication, the gas sprayed from the nozzle 2 is kept at the fastest rate, so that the flame is in a slender state; when the first convex hole 12 is connected to the second convex hole 22, the exhaust channel cross-sectional area remains medium, and the gas spray rate is medium at this time, so that the flame is in a medium thick and long state; when the multiple rows of holes 25 are connected to the first convex hole 12, the gas is branched again at this time, and the gas sprayed from the nozzle 2 is kept at the slowest rate, so that the flame is in the thickest and shortest state, and at this time, the multiple rows of holes 25 and the second column hole 21 and the second convex hole 22 synchronously spray flames, so that the flame on the nozzle 2 is in a flower shape, so that the flame on the performance ship can be performed in a variety of different performance changes to increase the performance effect.

[0055] Secondly, the air entering the air intake duct 31 flows toward the air intake hole 13, so that the air drawn into the air intake hole 13 enters the first column hole 11, so that more oxygen can be added to the gas during the flow process, which is convenient for the rapid combustion of the gas. At the same time, it also increases the oxygen demand of the nozzle 2 when spraying with different flames, and the air entering the exhaust duct 32 is located at the position of multiple holes 25, so that the oxygen in this part of the air can supplement the flame combustion, avoiding the lack of oxygen in the process of the wind shield 3 covering and protecting the holes 25.

[0056] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
