[0030] The rotary flame-spraying device according to the embodiment of the present application includes a base, on which a power assembly 10 and a flame-spraying assembly 20 are provided. The power assembly 10 is transmission-connected with the flame-spraying assembly 20 to drive the flame-spraying assembly 20 to rotate.

[0031] In detail, the flamethrower assembly 20 can spray flames, and the power assembly 10 is connected to the flamethrower assembly 20 in a transmission manner, and can drive the flamethrower assembly 20 to rotate. By controlling the power assembly 10, the flamethrower assembly 20 can be controlled to rotate at a desired angle, so that the rotation and rotation angle of the flamethrower assembly 20 can be controlled, thereby achieving a rotatable and angle-changeable flame effect.

[0032] like Figure 2 and Figure 3 As shown, according to the rotary flame spraying device of the embodiment of the present application, the power assembly 10 is used to provide power for the rotation of the flame spraying assembly 20, so as to control the rotation and the rotation angle of the flame spraying assembly 20.

[0033] According to the rotary flamethrower device of the embodiment of the present application, the power assembly 10 includes a transmission shaft 11 and a gas source adapter 12. The transmission shaft 11 is transmission-connected to the flamethrower assembly 20. One end of the transmission shaft 11 is rotationally connected to the gas source adapter 12. The gas source adapter 12 is used to communicate with the gas source. The gas source adapter 12 defines a first gas channel 121. A second gas channel 111 is defined in the transmission shaft 11. The first gas channel 121 is communicated with the second gas channel 111. The second gas channel 111 is communicated with the flamethrower end of the flamethrower assembly 20.

[0034] Specifically, the gas source adapter 12 is used to communicate with the gas source. A control valve 41 is provided on the pipeline 40 communicating with the gas source adapter 12. The control valve 41 can control the gas source to supply gas to the gas source adapter 12. One end of the transmission shaft 11 is rotatably connected to the gas source adapter 12. The first gas channel 121 is connected to the second gas channel 111. In this way, when the control valve 41 conducts the pipeline 40, the gas enters the first gas channel 121 and the second gas channel 111 through the gas source and finally enters the flame-spraying end of the flame-spraying assembly 20 and burns to generate flames. In this way, the gas source adapter 12 and the transmission shaft 11 are used to cooperate to meet the gas supply requirement for the rotating flame-spraying assembly 20.

[0035] like Figure 1-Figure 3 As shown, in some embodiments, the power assembly 10 includes a driving part 13 and a first transmission member 14, the driving part 13 and the first transmission member 14 are in transmission connection, a second transmission member 15 is provided on the transmission shaft 11, the first transmission member 14 and the second transmission member 15 are meshed, and the transmission shaft 11 and the second transmission member 15 cooperate to move synchronously.

[0036] In detail, the power assembly 10 includes a driving part 13 and a first transmission member 14, the driving part 13 and the first transmission member 14 are in transmission connection, the driving part 13 provides power for the rotation of the first transmission member 14, and a second transmission member 15 is provided on the transmission shaft 11, the first transmission member 14 and the second transmission member 15 are meshed, so that the first transmission member 14 can rotate under the drive of the driving part 13, and the rotation of the first transmission member 14 can drive the second transmission member 15 to rotate, and at the same time, the second transmission member 15 cooperates with the transmission shaft 11, the rotation of the second transmission member 15 drives the transmission shaft 11 to rotate, and the rotation of the transmission shaft 11 drives the flame-spraying assembly 20 to rotate. In this way, the flame-spraying assembly 20 is driven to rotate by using the power assembly 10, which has a simple structure, is easy to control, and has a low cost.

[0037] The transmission between the first transmission member 14 and the second transmission member 15 may be a screw transmission or a gear transmission; the first transmission member 14 and the second transmission member 15 may be in direct contact or may be transmitted through other components, which is not limited in the present application.

[0038] like Figure 1 As shown, in some embodiments, the first transmission member 14 includes a first transmission gear, and the second transmission member 15 includes a second transmission gear 151 .

[0039] In detail, the first transmission member 14 includes a first transmission gear, and the second transmission member 15 includes a second transmission gear 151. The first transmission gear and the second transmission gear 151 are meshed. It can be understood that the transmission ratio of the gear transmission is very precise and stable. At the same time, the gear transmission has precision and stability, and the transmission efficiency is very high. In this way, using the gear transmission method to control the rotation of the flamethrower assembly 20 can improve the stability and controllability of the rotation angle of the flamethrower assembly 20, and can control the flamethrower assembly 20 to achieve more designed flamethrower effects.

[0040] like Figure 1-Figure 3 As shown, in some embodiments, the second transmission member 15 also includes a fixing portion 152, the fixing portion 152 and the second transmission gear 151 are arranged in sequence along the axial direction of the transmission shaft 11 and fixedly connected, a plurality of fasteners 1521 are provided on the fixing portion 152, the transmission shaft 11 includes a limiting section 113, the limiting section 113 is provided with a plurality of limiting portions, and the fasteners 1521 cooperate with the limiting portions.

[0041] In detail, the multiple fasteners 1521 on the fixing portion 152 cooperate with the limiting portion on the transmission shaft 11, so that the fixing portion 152 and the limiting portion cannot move relative to each other and can only move synchronously. The fixing portion 152 and the second transmission gear 151 are arranged in sequence in the axial direction of the transmission shaft 11 and are fixedly connected. In this way, the second transmission gear 151 cooperates with the transmission shaft 11 to achieve a cooperation that can only move synchronously.

[0042] Among them, the fixed connection between the fixing part 152 and the second transmission gear 151 can be that the fixing part 152 and the second transmission gear 151 are integrally formed, the fixing part 152 and the second transmission gear 151 are welded and connected, or the fixing part 152 and the second transmission gear 151 are snap-connected to achieve that relative movement cannot occur between the second transmission gear 151 and the fixing part 152, and this application does not make any specific restrictions.

[0043] In addition, the fastener 1521 and the limiting portion may cooperate by being snap-fitted, abutted, or threadedly connected to the limiting portion, and this application does not impose any specific limitation.

[0044] like Figure 4 As shown, in some embodiments, the plurality of limiting portions are configured as a plurality of limiting surfaces, the plurality of limiting surfaces are sequentially arranged along the circumferential direction of the transmission shaft 11, and the fastener 1521 abuts against the limiting surfaces.

[0045] In detail, each limiting surface corresponds to at least one fastener 1521, and one end of the fastener 1521 close to the limiting surface abuts against the limiting surface, and the friction between the fastener 1521 and the limiting surface is used to prevent the fastener 1521 and the transmission shaft 11 from relative movement. The plurality of limiting surfaces are sequentially arranged along the circumferential direction of the transmission shaft 11, so that the transmission shaft 11 can be evenly hindered by the friction in multiple directions of the circumference, thereby preventing the transmission shaft 11 and the second transmission member 15 from relative rotation.

[0046] In order to further increase the friction between the fastener 1521 and the limiting surface, one end of the fastener 1521 that abuts against the limiting surface is provided with a planar end surface.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the transmission shaft 11 also includes a connecting section 112, the connecting section 112 has a mounting surface, the flamethrower assembly 20 also includes a bracket 21, the bracket 21 is connected to the mounting surface, and an adjacent ignition group 22 and a flamethrower 23 are provided on the bracket 21, and the flamethrower 23 is connected to the second gas channel 111.

[0048] In detail, the transmission shaft 11 also includes a connecting section 112, which has a mounting surface. The flamethrower assembly 20 also includes a bracket 21, which is connected to the mounting surface of the transmission shaft 11, so that the bracket 21 abuts against the mounting surface. Since the fuel combustion has a reverse thrust during flamethrowing, the support effect of the transmission shaft 11 on the bracket 21 is increased, making the flamethrower assembly 20 more stable on the transmission shaft 11 and less prone to shaking and loosening.

[0049] like Figure 1 and Figure 2 As shown, in some embodiments, the ignition group 22 includes at least one electronic igniter 221 , and the electronic igniter 221 is disposed around the flame nozzle 23 .

[0050] In detail, the ignition group 22 includes at least one electronic igniter 221, which can ignite the gas ejected from the burner nozzle 23. The electronic igniter 221 has the advantages of simple structure, safety, reliability and easy operation. It can not only reduce the production cost but also be environmentally friendly and suitable for popularization and use. The electronic igniter 221 is arranged around the burner nozzle 23 and can ignite the gas ejected from the burner nozzle 23 to achieve a variety of flame effects.

[0051] like Figure 1-Figure 3 As shown, in some embodiments, a support bearing 30 is further provided on the base, and the support bearing 30 is sleeved on the transmission shaft 11 .

[0052] In detail, a support bearing 30 is provided on the base, and the support bearing 30 is sleeved on the transmission shaft 11. The transmission shaft 11 rotates with the support of the support bearing 30. The support bearing 30 provides support force for the transmission shaft 11 and can reduce the friction between the transmission shaft 11 and the support bearing 30.

[0053] like Figure 4 As shown, in some embodiments, the transmission shaft 11 includes a round shaft segment 114 , and the round shaft segment 114 is located between the limiting segment 113 and the connecting segment 112 .

[0054] Specifically, the transmission shaft 11 includes a circular shaft section 114 , and the circular shaft section 114 is located between the limiting section 113 and the connecting section 112 . In this way, various structures can be arranged reasonably to reduce the overall volume of the rotary flame spraying assembly 20 .

[0055] like Figure 1 As shown, in a specific embodiment, the base is further provided with an execution control board 50, which is electrically connected to the drive unit 13, and the drive unit 13 can be configured as a motor, and the first transmission gear is connected to the output shaft of the motor. The execution control board 50 can communicate with the main control and control the drive unit 13 to execute corresponding instructions according to the instructions of the main control.
