[0002] A flamethrower is a stage special effects device, mainly used for special effects displays at large events such as stage performances and concerts, to create a lively and dynamic atmosphere. The main working principle of a flamethrower is as follows: the pumping system works to deliver fuel and other raw materials from the pipeline to the nozzle, causing the raw materials to be sprayed outward from the nozzle under a certain pressure, and then ignited by an ignition device to create a flame effect.

[0003] Currently, there are single-nozzle and multi-nozzle flamethrowers on the market, but the flames emitted by the nozzles of existing flamethrowers are of a single style and color, lacking visual appeal and failing to meet market demand. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a flame-throwing machine. The flame-throwing machine provided by this application can continuously change the color of the flame to achieve rich stage effects.

[0032] As shown in the figure, this utility model embodiment provides a flamethrower, including a flamethrowing device 1 and at least two flamethrowing components;

[0033] The flame-spraying device 1 is provided with nozzles 101 corresponding to the number of flame-spraying components, and each nozzle 101 is connected to a flame-spraying component.

[0034] Each of the flame-throwing components includes an oil storage device 2, a pumping device 3, and a spray valve 4. The oil storage device 2 is connected to the nozzle 101 through a delivery pipeline 5. The pumping device 3 and the spray valve 4 are respectively located on the delivery pipeline 5, and the spray valve 4 is located between the pumping device 3 and the nozzle 101.

[0035] This application provides a flamethrower, including a flamethrowing device 1 and at least two flamethrowing components. The flamethrowing device 1 is equipped with nozzles 101 corresponding to the number of flamethrowing components, and each nozzle 101 is connected to one flamethrowing component. Each flamethrowing component includes an oil storage device 2, a pumping device 3, and a spray valve 4. The oil storage device 2 is connected to the nozzle 101 via a delivery pipeline 5. The pumping device 3 and the spray valve 4 are respectively located on the delivery pipeline 5, with the spray valve 4 located between the pumping device 3 and the nozzle 101. The flamethrower provided by this application is equipped with at least two flamethrowing components, each of which is equipped with an oil storage device 2. This oil storage device can store fuel of different colors and textures or other raw materials for flamethrowing, and delivers them to the corresponding nozzle 101 for output through independent delivery pipelines 5. The pipelines do not interfere with each other, allowing for continuous changes in flame colors to achieve rich stage effects. By adjusting the pressure and spray time, flames of different durations and sizes can also be formed, further enriching the effects and meeting various needs of stage design and display.

[0036] Specifically, the flamethrower provided in this application operates as follows in each flamethrowing component: the pumping device 3 generates power, causing the raw materials stored in the oil storage device 2 to be transported along the conveying pipeline 5, while the raw materials are also atomized under pressure; when flamethrowing is needed, the spray valve 4 is opened, and the atomized raw materials are sprayed out from the corresponding nozzle 101. The flamethrowing device 1 ignites the atomized raw materials, thereby creating a flame effect. Since the color or other properties of the fuel and other raw materials stored in each oil storage device 2 differ, the resulting flame effects also differ. Therefore, by turning the corresponding flamethrowing component on and off as needed, or by switching between different flamethrowing components, a variety of stage effects can be provided.

[0037] Preferably, it is equipped with 3-10 flame-throwing components.

[0038] The flamethrower provided in this application can achieve effects such as spraying flames of different colors by setting two or more flame-spraying components. Preferably, 3-10 flame-spraying components are set, more preferably 4-8, and even more preferably 4-6. This allows for a greater number of flame colors to be sprayed, resulting in richer effects.

[0039] Preferably, the flame-spraying device 1 is further provided with a plurality of ignition mechanisms 102, and at least two ignition mechanisms 102 are distributed around each nozzle 101.

[0040] The flame-spraying device 1 specifically ignites the atomized material to form a flame through an ignition mechanism 102. The ignition mechanism 102 can be a high-voltage ignition electrode or the like, which is known in the art, and generates an electric spark by inputting high voltage to ignite the atomized material. The ignition mechanism 102 can also adopt other structures known in the art.

[0041] More preferably, the flame-spraying device 1 is also provided with multiple ignition mechanisms 102, with at least two ignition mechanisms 102 distributed around each nozzle 101, thereby ensuring the success rate of ignition.

[0042] Preferably, the number of ignition mechanisms 102 is the same as the number of nozzles 101, and the nozzles 101 and ignition mechanisms 102 are arranged alternately and connected end to end.

[0043] More preferably, the number of ignition mechanisms 102 is the same as the number of nozzles 101, and the nozzles 101 and ignition mechanisms 102 are arranged alternately and connected end to end. In this way, while ensuring that there are two ignition mechanisms 102 around each nozzle 101, the number of ignition mechanisms 102 is reduced and a lot of space can be saved.

[0044] The nozzles 101 and ignition mechanisms 102 are connected end to end and can be arranged in a ring, rectangle or other arbitrary shape. As long as the last ignition mechanism 102 is close to the first nozzle 101, it can be guaranteed that there are two ignition mechanisms 102 around any nozzle 101.

[0045] The flamethrower provided in this application has a flamethrowing device 1 that can be fitted with a housing to fix the nozzle 101 and the ignition mechanism 102 inside. It is small in size, durable, and easy to install.

[0046] Preferably, the delivery pipeline 5 is also provided with a filter 6.

[0047] The preferred delivery pipeline 5 is also equipped with a filter 6 to filter impurities in fuel oil and other raw materials, reducing their impact on flame effects and equipment operation. The preferred filter 6 is located at the upstream end of the delivery pipeline 5 (i.e., closest to the oil storage device 2) to ensure that all raw materials flowing through downstream structures are filtered by the filter 6.

[0048] Preferably, it also includes a return pipe 7;

[0049] The return pipeline 7 forms a loop between the injection valve 4 and the oil storage device 2, and the return pipeline 7 is also equipped with a pressure relief valve 8;

[0050] The conveying pipeline 5 is equipped with a one-way valve 9, which is located between the oil storage device 2 and the injection valve 4, and is used to allow the raw material to flow unidirectionally from the oil storage device 2 to the injection valve 4.

[0051] The preferred oil storage device 2 uses two different pipelines for raw material output and recovery: a conveying pipeline 5 for raw material output and a separate return pipeline 7 for returning unused raw material. A one-way valve 9 is installed on the conveying pipeline 5 to allow the raw material to flow unidirectionally from the oil storage device 2 to the injection valve 4; a pressure relief valve 8 is installed on the return pipeline 7. During injection, the pressure relief valve 8 is closed to maintain the pressure in the pipeline system, and after injection, opening the pressure relief valve 8 allows the pressure in the pipeline to drop rapidly. Excess raw material in the flame-throwing device 1 flows back through the return pipeline 7, preventing residual flames from affecting the appearance.

[0052] The injection valve 4 and the pressure relief valve 7 can each be independently selected from valves known in the art, such as solenoid valves.

[0053] The return line 7 forms a loop between the injection valve 4 and the fuel storage device 2. It can be that the two ends of the return line 7 are directly connected to the injection valve 4 and the fuel storage device 2 respectively, or the return line 7 and the delivery line 5 are connected upstream of the pumping device 3 and downstream of the check valve 9 respectively. As long as a fuel return channel can be formed, it is acceptable.

[0054] Preferably, an energy storage device 10 is also provided, which is used to store pressure or release the stored pressure;

[0055] The energy storage device 10 is installed on the delivery pipeline 5 and located between the pumping device 3 and the injection valve 4; or,

[0056] The energy storage device 10 is installed on the return pipeline 7 and located between the injection valve 4 and the pressure relief valve 8.

[0057] Preferably, an energy storage device 10 is also provided, which is used to store pressure or release the stored pressure, thereby eliminating pulses, increasing the injection time, and improving the stability of the flame.

[0058] Specifically, before the flame is ejected, the injection valve 4 is closed, the pumping device 3 works, which increases the pressure in the entire pipeline system, and the energy storage device 10 stores the pressure at the same time; when the flame is ejected, the injection valve 4 opens, and the fuel in the pipeline is continuously ejected. At this time, the energy storage device 10 also releases the pressure, and the auxiliary pumping device 3 maintains the pressure in the pipeline within the target range, so that the height and size of the ejected flame remain stable, allowing for the ejection of higher flames and increasing the injection duration.

[0059] The energy storage device 10 can be installed on the delivery pipeline 5 or the return pipeline 7, both of which can achieve the corresponding effect. When the energy storage device 10 is installed on the delivery pipeline 5, it is located between the pumping device 3 and the injection valve 4; when the energy storage device 10 is installed on the return pipeline 7, it is located between the injection valve 4 and the pressure relief valve 8.

[0060] The energy storage device 10 preferably adopts a structure that passively stores pressure after being subjected to external forces (such as the pumping device 3), which eliminates the need to set up a separate power mechanism for the energy storage device, resulting in a simple structure.

[0061] Preferably, a control module is also provided, which is electrically connected to the flame-spraying device 1, the pumping device 3, and the spray valve 4 respectively.

[0062] Preferably, the delivery pipeline 5 is also equipped with a pressure sensor 11, and the control module is electrically connected to the pressure sensor 11.

[0063] The preferred flamethrower also includes a control module. The control module is electrically connected to the flamethrower 1, the pumping device 3, and the spray valve 4, respectively, to control the working status of each structure, thereby enabling different flamethrower components to work or not work as needed, showcasing a variety of combined effects.

[0064] More preferably, a pressure sensor 11 is also provided on the delivery pipeline 5 to sense the pressure in the entire pipeline; the control module is electrically connected to the pressure sensor 11 and can control the operation of the flame-spraying device 1, the pumping device 3, and the spray valve 4 according to the pressure value, so as to adjust parameters such as flame size and maintain the working pressure of the equipment within a suitable range.

[0065] When both the control module and the pressure relief valve 7 are set, the pressure relief valve 7 can be opened or closed by the control module; the pressure relief valve 7 can also be opened without the control module, and a valve model that opens when a certain pressure is exceeded can be selected to achieve pressure relief.

[0066] Preferably, the control module is a programmable controller.

[0067] The preferred control module is a programmable logic controller (PLC). Specifically, the PLC can be a DMX512 controller or other PLCs known in the art.

[0068] Example 1

[0069] A flamethrower includes a flamethrowing device 1 and four flamethrowing components;

[0070] The flame-spraying device 1 is provided with four nozzles 101, each nozzle 101 being connected to a flame-spraying component; the flame-spraying device 1 is also provided with four ignition mechanisms 102, the nozzles 101 and the ignition mechanisms 102 are arranged alternately and connected end to end, so that two ignition mechanisms 102 are distributed around each nozzle 101.

[0071] Each flame-throwing assembly includes an oil storage device 2, a pumping device 3, a jet valve 4, a filter 6, an energy storage device 10, and a pressure sensor 11. It is also equipped with two pipelines: a delivery pipeline 5 and a return pipeline 7. The delivery pipeline 5 is equipped with a one-way valve 9, which is used to allow the raw material to flow unidirectionally from the oil storage device 2 to the jet valve 4. The return pipeline 7 is equipped with a pressure relief valve 8.

[0072] From the oil storage device 2 to the nozzle 101, the delivery pipeline 5 is successively equipped with a filter 6, a pumping device 3, a one-way valve 9, and a pressure sensor 11; from the oil storage device 2 to the nozzle 101, the return pipeline 7 is successively equipped with a pressure relief valve 8 and an energy storage device 10; and the connection points between the return pipeline 7 and the delivery pipeline 5 are one between the filter 6 and the pumping device 3, and the other between the one-way valve 9 and the nozzle 101.

[0073] It is also equipped with a control module, which is electrically connected to the flame-spraying device 1, the pumping device 3, the spray valve 4, and the pressure sensor 11 respectively.

[0074] The control module uses a DMX512 controller.

[0075] The working process of the aforementioned flamethrower is as follows:

[0076] The oil storage devices 2 of the four flame-spraying components store fuel of different colors as needed. The pumping device 3 starts working and pressurizes the fuel, and the fuel fills their respective pipelines. When the pressure sensor 11 detects that the pressure in the pipeline reaches the set pressure value, the control module stops the pumping device 3 from pressurizing, and the machine is in the ready-to-spray state.

[0077] When spraying is required, one or more of the four spray valves 4 can be opened at will. The atomized fuel sprayed by the corresponding nozzle 101 is ignited by the ignition mechanism 102 to form a flame. The flame color is different depending on the type of fuel. When the flame needs to disappear, the pressure relief valve 8 is opened to allow the fuel in the pipeline to flow back.

[0078] Under the signal control of the control module, the four injection valves 4 can be opened sequentially, or they can be opened randomly, simultaneously, alternately, or in combination. By injecting fuel of different colors, colored flames are formed after ignition, and the colorful flame effects are constantly changing, which increases the fun of watching.

[0079] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
