[0018] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] Please refer to Figure 1-2 A reusable fireworks tube includes a gas cylinder 1 for storing pressurized gas and a fireworks tube 4 for storing colored paper. The gas cylinder 1 is made of metal, preferably aluminum alloy or stainless steel. Colored paper strips or plastic confetti are placed inside the fireworks tube 4. The gas cylinder 1 is equipped with an inflation nozzle 2 and a manual sliding valve 3. One end of the fireworks tube 4 covers the manual sliding valve 3. The gas cylinder 1 and the fireworks tube 4 are connected or closed through the manual sliding valve 3.

[0020] In this embodiment, the inflation nozzle 2 is equipped with a one-way valve (not shown in the figure) to prevent the pressurized gas in the air cylinder 1 from leaking out of the inflation nozzle 1.

[0021] When in use, with the hand slide valve 3 closed, first connect the air nozzle 2 through a household air pump or other air inflation tool to allow air to gradually enter the air pump 1 and generate a certain pressure inside the air pump 1; when it is necessary to spray the ribbons or colored paper inside the firework tube 4, push and pull the air pump 1 to open the hand slide valve 3; at the moment the hand slide valve 3 opens, the pressurized gas inside the air pump 1 will be sprayed out from the hand slide valve 3 and blown towards the colored paper inside the firework tube 4, so that the colored paper is sprayed out from the port of the firework tube 4 to meet the needs of creating a festive atmosphere.

[0022] After the firework tube is used up, close the hand valve 3 again and inject pressurized air into the air cylinder 1 through the air nozzle 2; at the same time, fill the firework tube 4 with the prepared ribbon or colored paper; thus satisfying the needs of the next use. This cycle can greatly save air cylinder 1 and firework tube 4 and avoid single use.

[0023] For details, please refer to Figure 3-5 The hand slide valve 3 includes a sleeve 31, one end of which is provided with an air inlet 32 ​​and the other end with an air outlet 33. One end of the air inlet 32 ​​is connected to the air cylinder 1 by a thread, and the air outlet 33 extends into the firework tube 4.

[0024] The sleeve 31 has a sliding sleeve 34 on its outer circumference that can be slidably translated. The inner wall of the sliding sleeve 34 has an annular cavity 341. Both sides of the annular cavity 341 are provided with sealing rings 342. The sleeve 31 has a partition plate 311 inside, and both sides of the partition plate 311 are provided with an array of air holes 312.

[0025] In this embodiment, the purpose of setting two sets of sealing rings 342 is to seal the gap between the sliding sleeve 34 and the sleeve 31 to prevent internal air from leaking out.

[0026] Please refer to this again. Figure 4 When the air holes 312 on both sides of the partition 311 are located in the annular cavity 341, the air holes 312 on both sides of the partition 311 are connected through the annular cavity 341, which can realize the ventilation of the hand slide valve 3; after ventilation, the pressurized gas in the air cylinder 1 enters the annular cavity 341 from one set of air holes 312 (instantly), then enters the other set of air holes 312, and finally sprays into the firework tube 4 from the air outlet 33, thereby spraying out the colored paper, ribbons and other objects inside;

[0027] Please refer to this again. Figure 5When one of the sealing rings 342 is located between the two sets of air holes 312, the hand slide valve 3 closes; at this time, the gas in the air cylinder 1 cannot enter the other set of air holes 312 through the annular cavity 341, and the hand slide valve closes. This state can be used to inject air into the air cylinder 1, and can also be used for overall storage.

[0028] Understandably, the hand slide valve 3 can also use other valve bodies to control the flow of gas, thus meeting the requirements for the cyclic use of the fireworks tube.

[0029] In this embodiment, the inflation nozzle 2 is located at one end of the air cylinder 1, and the manual sliding valve 3 is located at the other end of the air cylinder 1.

[0030] Of course, a three-way valve can also be installed at one end of the air cylinder 1, with one valve port connected to the air cylinder 1, the other valve port connected to the inflation nozzle 2, and the remainder connected to the hand slide valve 3. This can also achieve the cyclic inflation of the air cylinder 1 and the cyclic use of the fireworks tube.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
