Referring to fig. 1, a cold flame apparatus 100 according to an embodiment of the present invention includes a mounting base 11, a gas supply assembly 10, a mixed gas pipeline 20, an explosive assembly 40, and a blanking assembly 50. Wherein the mounting 11 is used to provide a basis for the mounting of the gas tank and other components in the cold flame device 100. The gas supply assembly 10 is disposed on the mounting seat 11 for supplying a combustible gas. Mixing gas line 20 communicates between gas supply assembly 10 and explosive assembly 40. Explosive assembly 40 is disposed on mount 11 and has an explosive chamber 410. The blanking assembly 50 is disposed on an airflow path of the airflow emitted from the explosive assembly 40, and is used for providing consumables for the explosive assembly 40, and forms a spraying channel for instantly spraying the consumables together with the explosive assembly 40.

During the setting off process, the combustible gas provided by the gas supply assembly 10 is mixed with air through the mixed gas pipeline 20 and then is combusted and exploded in the explosion cavity 410, and the high-temperature and high-pressure gas 45 generated by explosion heats and excites the cold fireworks consumable 55 (shown in fig. 6) provided by the blanking assembly 50 and is blown out at high speed through the jet channel, so that the instant jet of the cold fireworks is realized. Because the gas generated by explosion has the characteristics of high temperature and high pressure, the cold flame consumable 55 in the accommodating cavity 51 is ejected at high speed along with the high-temperature and high-pressure gas 45, and the instant ejection of the cold flame is realized. Meanwhile, the high-temperature gas can be used to heat and excite the cold-flame consumable 55 without an independent consumable heating device, thereby simplifying the structure of the cold-flame apparatus 100.

Referring to fig. 1 and 2, the gas supply assembly 10 includes a gas inlet line 12 and a bottle opener 13, wherein the gas inlet line 12 is connected between the gas tank and the gas mixing line 20 for delivering the combustible gas in the gas tank to the gas mixing line 20.

Correspondingly, a mounting cavity 110 is formed in the mounting seat 11, and the gas tank is detachably connected in the mounting cavity 110. The bottle opener 13 is disposed in the setting cavity 110, when the gas tank is placed in the setting cavity 110, the gas outlet end of the gas tank is fixed to the bottle opener 13 and is opened, and the gas is released through the gas outlet end and flows into the mixed gas pipeline 20 through the gas inlet pipeline 12.

Referring to fig. 3 and 4, in particular, the bottle opener 13 includes a main body 131, a fixing member 132 and an opening member 133. The main body 131 is coupled in the installation cavity 110, and a gas passing channel 1310 is formed on the main body along the gas outflow direction in the gas tank, and the gas passing channel 1310 is communicated between the gas outlet end of the gas tank and the gas inlet pipeline 12. The fixing member 132 is provided on the body 131 and engaged with the gas outlet end of the gas tank, for fixing the gas tank received in the settling chamber 110 to the body 131. The opening member 133 is disposed on the main body 131 and is used for opening the gas tank so that the combustible gas in the gas tank is released into the gas passing passage 1310.

Further, the main body 131 is substantially hollow and cylindrical, and the hollow portion is a through-air passage 1310 penetrating along the axial direction thereof. Two axial end surfaces of the main body 131 are defined as an air inlet surface and an air outlet surface, and the air passage 1310 penetrates through the air inlet surface and the air outlet surface along the axial direction of the main body 131. The fixing element 132 is a buckle disposed on the air inlet surface of the main body 131 in this embodiment, and correspondingly, a slot for engaging with the buckle is disposed at the air outlet end of the air tank. When the gas tank is placed in the placement cavity 110, the gas tank can be fixed relative to the main body 131 by rotationally driving the buckle to be clamped in the clamping groove. The opening member 133 is, in this embodiment, a thimble provided at an end of the gas passing passage 1310 connected to the gas inlet surface, so that when the gas cylinder is fixed to the main body 131, the gas cylinder is opened by the thimble, and the release of the combustible gas is achieved. When the combustible gas in the gas tank is exhausted, an operator only needs to rotate to take out the gas tank and replace the gas tank, and the operation is convenient and quick.

It is understood that in other embodiments, the fixing member 132 may be other fixing structures for fixing the gas cylinder, such as a bolt, a removable snap-fit structure, etc., and only needs to fix the gas cylinder with respect to the main body 131, which is not limited herein. Meanwhile, the opening member 133 may be other opening structures for opening the gas tank, such as a rotary opening structure, and the like, and is not limited herein.

Referring to fig. 1 again, the gas supply assembly 10 further includes a check valve 14, and the check valve 14 is disposed at the gas inlet end of the gas inlet pipeline 12 and is used for only allowing the gas flow to flow from the gas tank into the gas inlet pipeline 12 and preventing the gas from flowing back into the gas tank through the gas inlet pipeline 12, so as to avoid generating a safety hazard.

Referring to fig. 5, a mixing chamber 210 communicating between the gas supply module 10 and the explosion module 40 is formed in the mixing gas pipeline 20, a suction port communicating with the outside is formed in a wall of the mixing chamber 210, when high-speed gas flows through the mixing chamber 210, the gas flow forms a negative pressure according to bernoulli's theorem, at this time, the outside gas is sucked into the mixing chamber 31 through the suction port and mixed with combustible gas, and at this time, the mixed combustible gas flows from the mixing chamber 210 into the explosion module 40. That is, the cold flame device 100 is configured to further simplify the device structure by drawing external air, mixing the external air with the combustible gas, and then exploding the mixture to the explosive assembly 40 to form the high-temperature and high-pressure gas 45 without additionally configuring an oxygen tank.

Further, mixing gas line 20 includes a tube 21 having a mixing chamber 210 and a nozzle 22 coupled to tube 21, and explosive assembly 40 includes an explosive device 41 having an explosive chamber 410. The nozzle 22 is connected between the air intake pipe 12 and the pipe body 21, and the pipe body 21 is connected between the nozzle 22 and the exploder 41. Meanwhile, the inner cavity of the air intake pipeline 12, the mixing cavity 210 and the explosion cavity 410 are communicated with each other, so as to form an airflow channel for the combustible gas in the air intake pipeline 12 to flow to the explosion cavity 410 after being mixed with air through the mixing cavity 210.

Specifically, the nozzle 22 includes a spraying section connected between the air supply assembly 10 and the mixing chamber 210, and the cross-sectional area of the spraying section is gradually reduced from the air supply assembly 10 toward the mixing chamber 210. In this way, after the combustible gas provided by the gas supply assembly 10 enters the injection section from the gas inlet pipeline 12, the cross-sectional area of the injection section is gradually reduced, so that the gas flow passing through the injection section is continuously accelerated and ejected at a high speed, and thus a high-speed gas flow is formed and enters the mixing chamber 210.

In this embodiment, the nozzle 22 further includes a connecting section connected between the air inlet pipeline and the injection section, the connecting section is substantially hollow, the injection section is connected between the connecting section and the mixing chamber 210, and a jet opening is formed on a side of the injection section facing the mixing chamber 210. In the present embodiment, the cross-sectional area of the injection section is gradually reduced from the connection section to the mixing chamber 210, and the cross-sectional area of the injection port is smaller than that of the connection section. Thus, when the combustible gas provided by the gas supply assembly 10 sequentially enters the connecting section and passes through the injecting section from the gas inlet pipeline 12, since the sectional area of the injecting section is gradually reduced towards the direction far away from the connecting section, the gas flow passing through the injecting section is continuously accelerated and is ejected at a high speed through the jet orifice with the minimum sectional area of the nozzle 22, so that a high-speed gas flow is formed and enters the mixing chamber 210.

Referring to fig. 1 and 5 again, the cold flame device 100 further includes a control assembly 30, the control assembly 30 includes a main board 31 and a battery box 32, the main board 31 and the battery box 32 are disposed on the mounting base 11, and a plurality of control buttons are disposed on the main board 31 and the battery box 32, so that a user can operate the control buttons to adjust device parameters and control the device to operate in a wired manner. It is understood that, in other embodiments, the device may also be controlled to operate in a wireless manner, and only the real motherboard 31 needs to control the device, which is not limited herein. A battery box 32 is disposed on the mounting base 11 for providing power to the cold flame apparatus 100. In addition, the main board 31 is also used for monitoring the voltage in the battery box 32, so as to remind the user of timely charging or replacing the battery box 32 when the voltage is too low.

Further, the control assembly 30 further includes a solenoid valve 33, and the solenoid valve 33 is coupled to the air intake pipeline 12 and is in control connection with the main board 31, so that when the device operates, the main board 31 controls the solenoid valve 33 to open and close, thereby controlling the on/off of the air intake pipeline 12.

Further, the control unit 30 further comprises a pressure sensor 34, and the pressure sensor 34 is connected to the main board 31 for monitoring the gas pressure in the intake pipe 12. The main board 31 is used for processing and displaying the received air pressure data, and a user can learn the state of the whole device more intuitively through the main board 31.

Still further, the control assembly 30 further includes an igniter 35, and the igniter 35 is mounted on the exploder 41 and ignites the gas in the explosion chamber 410 of the exploder 41 to ignite the mixed combustible gas in the explosion chamber 410. After the mixed combustible gas is filled in the explosion cavity 410 for a period of time, the electromagnetic valve 33 can be disconnected, the pressure is boosted through the main board 31 boosting module, the igniter 35 discharges to ignite the mixed combustible gas, the mixed combustible gas can be combusted and exploded to complete one-time cold firework injection, and the mixed combustible gas is filled in the explosion cavity 410 again to perform the next injection, so that the whole equipment can be repeatedly and continuously used.

Explosive assembly 40 further includes a shaft 42, a puck 43, and a lock 44. Wherein, the exploder 41 is rotatably arranged relative to the mounting base 11 through a rotating shaft 42, and the positioning disc 43 is fixedly arranged on the exploder 41 and rotates synchronously with the exploder 41. The locking member 44 is provided on the mount 11 and is controlled to lock the puck 43 or unlock the puck 43.

In this embodiment, the rotating shaft 42 is disposed on the exploder 41 along its axial direction, and two axial ends of the rotating shaft protrude out of the exploder 41 and are rotatably connected with the mounting base 11, so as to rotate the exploder 41 relative to the mounting base 11. It is understood that in some other embodiments, the rotating shaft 42 may be disposed to be fixed to the mounting seat 11 along the axial direction, and the exploder 41 may rotate around the rotating shaft 42 under the external force, which only needs to realize the angle adjustment of the exploder 41 relative to the mounting seat 11, and is not limited herein.

The periphery of the positioning plate 43 is configured to form a plurality of slots, and the locking member 44 is fixedly disposed above the positioning plate 43 and includes a positioning pin 440. The positioning pin 440 is slidably coupled to the mounting base 11 along its axial direction and detachably engaged with the engaging groove of the positioning plate 43, so that the positioning pin 440 is engaged with the engaging groove to fix the exploder 41 relative to the mounting base 11, and the positioning pin 440 is disengaged from the engaging groove to allow the exploder 41 to freely rotate relative to the mounting base 11.

Further, the pull ring 441 of the locking member 44 is disposed at the other end of the positioning pin 440 far from the positioning plate 43, and is controlled to drive the positioning pin 440, so as to separate the positioning pin 440 from the catch groove, so as to unlock the positioning pin 440 from the positioning plate 43, thereby unlocking the positioning pin 440 from the exploder 41, and further realizing the free rotation of the exploder 41.

Meanwhile, in the present embodiment, a spring (not shown) is disposed on the locking member 44, one end of the spring is fixedly connected to the locking member 44, and the other end of the spring abuts against the mounting seat 11. Under the condition of no pulling force, the locking piece 44 is clamped in one of the clamping grooves of the positioning disc 43 under the action of elastic force, and at the moment, the locking piece 44 is locked with the positioning disc 43, so that the angle of the exploder 41 is fixed. When pulling locking piece 44 upwards, locking piece 44 cooperation end and positioning disk 43 draw-in groove separation, positioning disk 43 loses the block, lets explosive device 41 rotate through pivot 42 this moment, and the angle of explosive device 41 can be changed to the positioning disk 43 draw-in groove of rethread change locking piece 44 block. It can be understood that, in other embodiments, the locking member 44 does not need a spring, and may be directly engaged with one of the slots of the positioning plate 43 by using its own gravity under the condition of no pulling force, and the locking member 44 may be engaged with one of the slots of the positioning plate 43 only when no pulling force is needed, which is not limited herein.

Referring to fig. 6, the blanking assembly 50 has a receiving cavity 51 for receiving the cool flame consumable 55 and a discharge hole 52, the discharge hole 52 is communicated with the explosion cavity 410 to form the above-mentioned injection channel, and the receiving cavity 51 is communicated with the injection channel, so that the cool flame consumable 55 received in the receiving cavity 51 can be heated and excited by the high-temperature high-pressure gas 45 flowing through the injection channel at a high speed and carried out, thereby completing the injection of the cool flame.

Specifically, the discharge port 52 penetrates through two opposite ends of the blanking assembly 50, and the accommodating cavity 51 is surrounded on the periphery of the discharge port 52, so that the cool firework consumables 55 are uniformly provided for the discharge port 52 from the circumferential direction. Meanwhile, a groove is arranged at the communication position of the accommodating cavity 51 and the injection channel, and the cold firework consumables 55 are exposed and accumulated in the groove under the normal condition, and are heated, excited and carried out by the high-temperature high-pressure gas 45 during injection. When the cold flame and fire consuming material 55 in the groove is consumed, the vibration of gravity and explosion is supplemented by the cold flame and fire consuming material 55 above, so that the whole process automatically realizes blanking without a redundant blanking device, and the structure of the whole cold flame and fire equipment 100 is further simplified; meanwhile, material blockage can not occur, and the failure rate is reduced.

More specifically, the blanking assembly 50 comprises an upper bin 53 and a lower bin 54 which are jointly configured to form an accommodating cavity 51, wherein the upper bin 53 and the lower bin 54 are detachably butted and are spaced to form a groove; and the positions of the upper bunker 53 and the lower bunker 54 along the butt joint direction can be adjusted to change the flow area of the groove. The adjustment of the flow area of the grooves can change the blanking amount so as to realize different spraying effects.

In this embodiment, the upper bin 53 and the lower bin 54 are detachably assembled through a threaded structure, so that when a user adds the cool firework consumables 55, the cool firework consumables 55 can be loaded into the accommodating cavity 51 only by disassembling the upper and lower parts of the lower component 50. It is understood that in other embodiments, the upper bin 53 and the lower bin 54 may also be connected by other connection methods, such as a quick-fastening connection, and only the upper bin 53 and the lower bin 54 are required to be in butt-joint fit, which is not limited herein.

Further, because the exploder 41 can rotate relative to the mounting seat 11, the discharge hole 52 of the blanking assembly 50 can also rotate along with the rotation of the exploder 41, so that the injection angle of the injection channel is changed, the multi-angle injection of the cold flame and the fire is realized, more watching effects are created, and meanwhile, when multiple devices are linked with each other, more abundant visual experience can be brought, and more performance requirements are met.

In the process of setting off the cold flame device 100, the combustible gas provided by the gas supply assembly 10 is mixed with air through the mixed gas pipeline 20 and then is combusted and exploded in the explosion assembly 40, and the high-temperature and high-pressure gas 45 generated by explosion heats and excites the cold flame consumable material 55 provided by the blanking assembly 50 and is blown out at high speed through the jet channel, so that the instant jet of the cold flame is realized. Because the gas generated by explosion has the characteristics of high temperature and high pressure, the cold flame fire consumable material 55 blanked by the blanking assembly 50 obtains a higher speed along with the high-temperature and high-pressure gas 45, thereby realizing the instant injection of the cold flame fire.

By using the high temperature gas, the heating excitation of the cold flame consumables 55 can be realized without a separate consumable heating device, thereby simplifying the structure of the cold flame apparatus 100. By Bernoulli's theorem, the nozzle 22 generates high-speed airflow to form negative pressure, and then outside air is sucked into the mixing chamber 210 to be mixed with combustible gas and then led to the explosion assembly 40 to explode to form high-temperature and high-pressure gas 45, without additionally arranging an oxygen tank, thereby further simplifying the structure of the cold flame fire device 100. In addition, when the cold flame and fire consuming material 55 in the groove of the blanking bin 54 is consumed, the cold flame and fire consuming material 55 above is supplemented due to gravity and explosion vibration, and the blanking is automatically realized in the whole process without a redundant blanking device. The blanking assembly 50 simplifies the blanking structure and the feeding structure of the traditional consumable materials, integrates the blanking structure and the feeding structure together, solves the problem that the traditional cold flame fire equipment is easy to clamp materials, and reduces the failure rate.

The mixed combustible gas is combusted and exploded to complete one-time cold firework injection, and the mixed combustible gas is filled in the explosion cavity 410 again to be injected next time, so that the whole equipment can be repeatedly and continuously used, and the combustible gas tank can be conveniently and easily obtained by using a common cassette type furnace gas tank on the market. It is understood that other combustible gases and atomized combustible liquids, such as coal gas, natural gas, hydrogen, etc., can be used as the combustible gas, and the combustible gas can be mixed with air and then combusted and exploded, and is not limited herein.

The device can also flexibly adjust the spraying angle according to the requirements of users and performances, creates more watching effects, can bring rich visual experience by linkage of multiple devices, and adapts to more users and performances.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
