Description

Large-thrust firework Technical Field The utility model relates to the field of fireworks, in particular to a high-thrust firework. Background In the structural design of traditional fireworks, propellant powder is usually filled in the bottom of a transmitting cylinder, and after the bottom of the transmitting cylinder is plugged through paper sheets, an effect inner cylinder is filled in the transmitting cylinder. However, the assembly mode has some defects when the fireworks are actually used, and needs improvement. On one hand, the thrust generated by the propellant powder is easily influenced by the gap between the propellant canister and the effect inner canister in the transmission process, so that energy loss is caused, the emission height of fireworks is limited, and on the other hand, the effect inner canister is easy to appear rolling phenomenon due to uneven stress and other factors in the rising process, so that the stability and ornamental value of fireworks are influenced when the fireworks are set off. Therefore, a high-thrust firework is provided to solve the problems. Disclosure of utility model In order to make up for the defects, the utility model provides a high-thrust firework, and aims to solve the problems that the propellant thrust transmission energy loss is large and the launching height of the firework is limited in the prior art. In order to achieve the aim, the high-thrust firework comprises a launching tube, wherein the top end of the inner wall of the launching tube is fixedly connected with sealing paper, the upper part of the sealing paper is provided with an ignition component, and the launching tube is internally provided with a launching component; The utility model discloses a light emitting device, including the effect inner tube, the effect inner tube pressure equipment is in the bottom of transmission section of thick bamboo inner wall, the middle section fixedly connected with shutoff scraps of paper of effect inner tube inner wall, the cavity has been seted up to the inner wall of effect inner tube, be located in the effect inner tube the top of shutoff scraps of paper is packed with propellant powder, clay festival and reputation medicine from supreme in proper order down.
