[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. In this utility model, high-pressure gas in the air chamber enters the transition chamber and the air outlet through the air outlet, triggering the pressing and activating mechanism to release the high-pressure gas from the air outlet into the confetti tube body. This causes the confetti inside the confetti tube body to be released under high pressure. After removing the confetti tube body, the pressing and activating mechanism is reset, and the air canister cap is rotated so that the air inlet is aligned with the air outlet of different air chambers. A new confetti tube body can then be installed for continued use. This allows one air canister body to activate multiple confetti tube bodies multiple times. After activation and use, the air canister body will not be scrapped along with the confetti tube body, reducing the usage cost of pneumatic fireworks.

[0022] 2. In this utility model, pressing the activation button pushes the hook to rotate. At this time, the spring is squeezed by the hook and the air outlet pipe. According to the lever principle, the hook is disengaged from the cover. The cover rotates under the high pressure in the air outlet pipe. The high pressure gas in the air outlet pipe is released into the colored paper tube body, completing the press activation. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-8 This utility model provides a technical solution: a lightweight firework device that can be launched by pressing, comprising:

[0035] The gas tank body 1 is a round tank, and multiple gas chambers 2 are provided inside the gas tank body 1. The top surface of each gas chamber 2 is provided with an air outlet 3, and the multiple air outlets 3 are arranged in a ring array along the axis of the gas tank body 1.

[0036] A gas cylinder cover 4 is hinged to the top of the gas cylinder body 1, and the gas cylinder cover 4 blocks multiple gas outlets 3. A transition chamber 5 is provided inside the gas cylinder cover 4. A gas outlet pipe 6 is provided at the top of the gas cylinder cover 4 and the gas outlet pipe 6 is connected to the transition chamber 5. A gas inlet 7 is provided on the bottom surface of the gas cylinder cover 4 and the gas inlet 7 is connected to any of the gas outlets 3.

[0037] The pressing and triggering mechanism 8 is connected to the air outlet pipe 6, and the pressing and triggering mechanism 8 blocks the end of the air outlet pipe 6;

[0038] The colored paper tube body 9 is fitted onto the gas can cover 4, and the colored paper tube body 9 covers the pressing and triggering mechanism 8;

[0039] The press-activated mechanism 8 includes a fixing clamp 81, a cover 82, a hook 83, and an activation button 84. The fixing clamp 81 is connected to the air outlet pipe 6. The cover 82 is hinged to the fixing clamp 81 and blocks the air outlet pipe 6. The middle part of the hook 83 is hinged to the fixing clamp 81. One end of the hook 83 is stuck to the cover 82, and the other end of the hook 83 is connected to the air outlet pipe 6 through a spring 10. The activation button 84 is slidably connected to the fixing clamp 81. The end of the activation button 84 abuts against the hook 83. Pressing the activation button 84 pushes the hook 83 to rotate. At this time, the spring 10 is squeezed by the hook 83 and the air outlet pipe 6. According to the lever principle, the hook 83 is disengaged from the cover 82. The cover 82 rotates under the high pressure in the air outlet pipe 6. The high-pressure gas in the air outlet pipe 6 is released into the colored paper tube body 9, completing the press-activated mechanism.

[0040] The trigger button 84 is fitted with a safety stop block 11 to prevent accidental activation of the trigger button 84.

[0041] The colored paper tube body 9 is provided with an anti-cavity groove 12, which is aligned with the activation button 84 to ensure that the activation button 84 does not interfere with the colored paper tube body 9 when it is pressed.

[0042] The end of the vent pipe 6 is fitted with a sealing plug 13 to prevent gas from leaking from the vent pipe 6.

[0043] The colored paper tube body 9 is provided with a firework chamber 14, which is located above the air outlet pipe 6.

[0044] Working principle: First, the high-pressure gas in the air chamber 2 enters the transition chamber 5 and the air outlet pipe 6 through the air outlet 3, triggering the press-activated mechanism 8 to release the high-pressure gas from the air outlet pipe 6 into the colored paper tube body 9. That is, pressing the activation button 84 pushes the hook 83 to rotate. At this time, the spring 10 is squeezed by the hook 83 and the air outlet pipe 6. According to the lever principle, the hook 83 disengages from the cover 82. The cover 82 rotates under the high pressure in the air outlet pipe 6, and the high-pressure gas in the air outlet pipe 6 is released into the colored paper tube body 9, completing the press-activated mechanism, so that the gas inside the colored paper tube body 9... The colored paper is released under high pressure. Next, after removing the colored paper tube body 9, the activation mechanism 8 is reset and pressed, that is, the cover 82 is re-blocked on the air outlet pipe 6. After the spring 10 is reset, the hook 83 is re-locked on the cover 82 under the action of the spring 10. Finally, the air tank cover 4 is rotated so that the air inlet 7 is aligned with the air outlet 3 of different air chambers 2. A new colored paper tube body 9 can be replaced and it can be used again. This allows one air tank body 1 to activate multiple colored paper tube bodies 9 multiple times. After the air tank body 1 is activated and used, it will not be scrapped along with the colored paper tube body 9, which reduces the use cost of pneumatic fireworks.
