A flow pipe 5 is provided between the flow chamber 11 and the mixed explosion chamber 12, with one end facing the nozzle 3 and the other end connected to the mixed explosion chamber 12. An air inlet 14 connected to the outside of the gun barrel 1 is provided on the side wall of the gun barrel 1 at the position of the flow chamber 11. The ignition head 41 of the igniter 4 is located in the mixed explosion chamber 12. Each stage of detonation chamber 13 in the gun barrel 1 has a partition 15 on the side near the mixed explosion chamber 12. Each partition 15 has a detonation hole 16 with an area that increases from the mixed explosion chamber 12 to the rear.

[0011] The detonation holes 16 on each partition 15 are circular holes located at the center of the partition 15.

[0012] The area of ​​the detonation holes 16 on each partition 15 is arranged in order from the mixed explosion chamber 12 to the rear, with each subsequent stage being 1.1 to 1.5 times the size of the previous stage.

[0013] The volume of each detonation chamber 13 is arranged in order from the mixed detonation chamber 12 to the next, with each subsequent chamber being 1.1 to 1.5 times the volume of the previous chamber.

[0014] The gun barrel 1 is equipped with 3-7 level detonation chambers 13.

[0015] The barrel 1 has a transparent wall so that the flash produced during firing can be seen at night, which can improve the viewing experience.

[0016] The outer wall of the drainage pipe 5 is provided with external threads. Nuts 51 located in the drainage chamber 11 and the mixing chamber 12 are respectively installed on the drainage pipe 5 by the threads. The drainage pipe 5 is installed in the gap between the drainage chamber 11 and the mixing chamber 12 by the two nuts 51. The distance between the drainage pipe 5 and the nozzle 3 can be adjusted back and forth to achieve the best drainage and mixing effect.

[0017] The mixed-explosion chamber 12 is equipped with a mixed-gas baffle 17 that is directly opposite the gas outlet of the diversion pipe 5 and is spaced apart from the diversion pipe 5 by a certain distance. Several mixed-gas passage holes 18 are provided between the outer side of the mixed-gas baffle 18 and the inner wall of the barrel 1.

[0018] It includes a cylindrical barrel 6 with the front half being the barrel 1, an igniter 4 located behind the barrel 1 and installed inside the barrel 6, an igniter button 42 exposed outside the barrel 6, and the igniter 4 connected to the ignition head 41 located in the mixed explosion chamber 12 via a wire.

[0019] The gas storage and injection device 2 is composed of an injection valve 21 and a gas storage chamber 22. The injection valve 21 is installed in the cannon barrel 6 behind the igniter 4, and the injection valve button 23 is exposed outside the cannon barrel 6.

[0024] The igniter 4 is a piezoelectric ceramic igniter.

[0025] A cross-shaped anti-plug blocking frame 19 (see Figure 1 ) is provided at the cannon mouth position of the front end of the cannon barrel 1, so as to prevent foreign matters from being inserted into the front end of the cannon barrel 1, which may cause the cannon barrel 1 to burst when sounding.

[0026] An end cover 20 sleeved on the cannon barrel 1 is provided at the cannon mouth position of the front end of the cannon barrel 1. A plurality of lateral sounding holes 30 (see Figure 2 ) are provided on the side wall of the end cover 20 and the cannon barrel 1 in a sleeved and matched manner.

[0028] The gas charging port of the injection seat 8 is provided with an O-shaped sealing ring 83 which is matched with the nozzle of the gas cylinder 7, the rear of the sealing ring 83 is provided with a nozzle guide ring 84 which is installed in the gas charging port through screw thread and has a large inner diameter at the rear and a small inner diameter at the front, the front of the sealing ring 83 is provided with an inner step 85 which is matched with the nozzle of the gas cylinder 7, and the center of the inner step 85 is provided with a gas charging hole 86 which is connected with the gas outlet port.

[0029] The rear control sleeve 81 is pulled to make the injection seat 8 retract and compress the end face of the inner step 85 with the nozzle of the gas cylinder 7, so that the nozzle can be opened to spray gas outward. When the gas cylinder 7 is replaced, the empty gas cylinder 7 is pulled out and a new gas cylinder 7 is replaced, the elastic outer clamping wedges 91 are retracted and then elastically clamped into the inner clamping grooves 71 on the outer periphery of the nozzle of the gas cylinder 7, so that the gas cylinder 7 can be reliably installed on the gas cylinder connecting seat 9.

[0030] In the embodiment three, Figure 3As shown, the difference from Embodiment 1 is that the gas storage and injection device 2 is a gas cylinder 7, and the cannon barrel 6 is provided with an injection seat 8 located behind the igniter 4. The injection seat 8 is provided with an injection port that matches the nozzle of the gas cylinder 7 and an outlet that is connected to the air inlet of the nozzle 3 through a gas pipe. The cannon barrel 6 behind the injection seat 8 is provided with a gas cylinder connecting seat 9 that slides axially with the cannon barrel 6. The cannon barrel 6 at the corresponding position of the gas cylinder connecting seat 9 is provided with a control sleeve 81 that is movably fitted on the cannon barrel 6. The side wall of the cannon barrel 6 between the control sleeve 81 and the gas cylinder connection seat 9 is provided with several strip holes 62 extending along the axial direction of the cannon barrel 6. The control sleeve 81 and the gas cylinder connection seat 9 are connected to each other by several connecting pins 82, one end of which is connected to the control sleeve 81, the other end of which is connected to the gas cylinder connection seat 9, and the middle part passes through the strip holes 62. The gas cylinder connection seat 9 is provided with elastic outer wedges 91 that are divided into several parts in the circumferential direction to cooperate with the inner groove 71 on the outer periphery of the gas cylinder 7 nozzle. The front half of the gas cylinder 7 is located inside the cannon barrel 6 and is engaged with the gas cylinder connection seat 9, while the rear half is located outside the cannon barrel 6, so as to facilitate the insertion and removal of the gas cylinder 7.

[0031] The gas filling port of the gas filling seat 8 is provided with an O-ring seal 83 that matches the nozzle of the gas cylinder 7. Behind the seal 83 is a nozzle guide ring 84 with a larger inner diameter at the back and smaller inner diameter at the front, which is installed on the gas filling port by threads. In front of the seal 83 is an inner step 85 that matches the nozzle of the gas cylinder 7. At the center of the inner step 85 is a gas filling hole 86 that communicates with the gas outlet.

[0032] Pushing the control sleeve 81 forward causes the gas cylinder connector 9 to extend forward, compressing the gas cylinder 7 nozzle against the end face of the inner step 85, allowing the nozzle to be opened and gas to be expelled. Replacing the gas cylinder 7 is the same as in Embodiment 2.

[0033] Example 4, as Figure 4 As shown, the difference from Embodiment 1 is that the gas storage and injection device 2 is a gas cylinder 7. The cannon barrel 6 is provided with an injection seat 8 located behind the igniter 4 and radially sliding with the cannon barrel 6. One end of the injection seat 8 in the sliding direction is provided with an injection button 87 that passes through the side wall of the cannon barrel 6 and protrudes outside the cannon barrel 6. The injection seat 8 is provided with an inflation port that matches the nozzle of the gas cylinder 7 and an exhaust port that is connected to the air inlet of the nozzle 3 through a gas pipe. On the side opposite to the inflation port, the cannon barrel 6 is provided with a gas cylinder connecting seat 9 horizontally installed on the cannon barrel 6. The gas cylinder connecting seat 9 is provided with an elastic outer wedge 91 that is divided into several parts in the circumferential direction and matches the inner groove 71 on the outer periphery of the nozzle of the gas cylinder 7. The gas cylinder connecting seat 9 is provided with a gas cylinder sleeve 92 connected to the cannon barrel 6 at one end. The front half of the gas cylinder 7 is inserted into the gas cylinder sleeve 92 and engaged with the gas cylinder connecting seat 9, and the rear half is located outside the gas cylinder sleeve 92, so as to remove and replace the gas cylinder 7.

[0034] The gas injection seat 8 is provided with an O-shaped sealing ring 83 matched with the nozzle of the gas cylinder 7. The rear of the sealing ring 83 is provided with a nozzle guide ring 84 with a large inner diameter at the rear and a small inner diameter at the front, which is screwed on the gas injection port. The front of the sealing ring 83 is provided with an inner step 85 matched with the nozzle of the gas cylinder 7. The center of the inner step 85 is provided with a gas injection hole 86 connected with the gas outlet.

[0035] Pressing the gas injection button 87 of the gas injection seat 8 can compress the nozzle of the gas cylinder 7, so that the nozzle is opened to discharge gas outward. When replacing the gas cylinder 7, the empty gas cylinder 7 is pulled out from the gas cylinder connecting seat 9, and then the new gas cylinder 7 is inserted into the gas cylinder sheath 92 and clamped with the gas cylinder connecting seat 9.

[0036] The gas cylinder 7 is a butane cylinder or other type of gas cylinder.

[0037] Method of use:

[0038] If the gas storage and injection device 2 adopts the gas storage chamber 22 of example one, the gas cylinder 7 needs to be used to charge the gas storage chamber 22 before use. The nozzle of the gas cylinder 7 is aligned with the gas injection valve 24 at the rear of the gas storage chamber 22, and the nozzle is compressed to open the nozzle to charge the gas storage chamber 22. By observation, the liquid volume is charged to about half of the capacity of the gas storage chamber 22.

[0039] When in use, the barrel 6 is held by hand, and the gas outlet of the barrel 1 is directed upward or upward and obliquely. Then the gas injection valve button 23 is pressed to open the gas injection valve 21, and the gas is injected into the flow guide pipe 5 through the nozzle 3. The high-speed ejected gas will generate suction force to carry the air in the flow guide chamber 11 into the mixing explosion chamber 12. Under the blocking action of the gas mixing baffle 18, the gas and air are fully mixed and contacted in the mixing explosion chamber 12. When the appropriate amount of gas injection is reached, the gas injection is stopped. When the firecracker is fired, the igniter button 42 is pressed, and an electric spark is generated between the positive and negative electrodes of the ignition head 41, so that the mixed gas explodes in the mixing explosion chamber 12 and is ejected from the front end of the barrel 1 through the various explosion chambers 13 in the barrel 1, producing a loud sound of the firecracker. Pressing the gas injection valve button 23 and the igniter button 42 in turn again can continue to inject gas and ignite, so as to fire again. When the gas volume in the gas storage chamber 22 is insufficient, the gas cylinder 7 can be used again to supplement the gas.

[0040] If the gas cylinder 7 of examples two, three and four is used as the gas storage and injection device 2, the gas cylinder 7 needs to be inserted into the barrel 6 or the gas cylinder sheath 92, so that the gas cylinder 7 is reliably connected with the gas cylinder connecting seat 9.

[0041] When using, one hand holds the barrel 6, the other hand pulls or pushes the control sleeve 81, or holds the barrel 6, presses the gas injection button 87, compresses the nozzle of the gas cylinder 7 to open it, and injects gas into the mixed explosion chamber 12 through the nozzle 3 and the flow guide pipe 5, and stops injecting gas when the appropriate amount of gas is injected. The sounding method is the same as above. When the gas in the gas cylinder 7 is insufficient, the gas can be supplemented by replacing the gas cylinder 7.

[0042] It can be repeatedly used, which can not only reduce the use cost, but also be beneficial to energy saving and environmental protection.
