Detailed Description

Referring to the drawings, a specific structure of the utility model is reflected. The balloon-shaped toy firework utilizing pyrotechnic composition to make gas and inflate comprises a firework barrel 1 and a balloon 11, wherein a top port of the firework barrel 1 is sealed by a paper layer 4 and a moisture-proof adhesive layer 6 and is embedded and fixed with a firing cable 5; the air inlet 13 of the balloon 11 is fixedly sleeved on the bottom port of the firework barrel 1 in an adhesive manner; the inner cavity of the firework barrel 1 close to the bottom port is provided with a gas cooling channel, the gas cooling channel comprises a gas permeation layer 9 and a gas nozzle 12 which are connected up and down, the gas permeation layer 9 is formed by flame retardant particles (such as 8-14 meshes of sand) filled in the firework barrel, the gas nozzle 12 is provided with a hole cavity 14 through which gas passes, the upper port of the hole cavity 14 is provided with a sealing cover, the sealing cover is provided with a gas passing hole 10, and the flame retardant particles cannot enter the hole cavity 14 through the gas passing hole 10; in this embodiment, the width of the over-pores 10 is smaller than the particle size of the fire-retardant particles, and the length of the over-pores 10 is much larger than the width, so as to ensure that the over-pores 10 are not blocked by the fire-retardant particles. The air nozzle 12 is fixed between the air permeation layer 9 and the bottom end port, and the inner cavity of the firework barrel 1 between the air permeation layer 9 and the top end port is loaded with gas making pyrotechnic compositions 2.
