The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiments of the present invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 and 2, the firework inner barrel comprises an inner barrel body 4, an effect powder cavity 5 is arranged at the top of the inner barrel body 4, an ignition powder cavity 3 is arranged at the bottom of the inner barrel body 4, a sealing layer 7 is arranged between the effect powder cavity 5 and the ignition powder cavity 3, a connecting channel 2 is arranged in the middle of the sealing layer 7, and the connecting channel 2 is communicated with the effect powder cavity 5 and the ignition powder cavity 3.

Specifically, as shown in fig. 3, the sealing layer 7 of the present embodiment includes a sealing plate 6 and a channel plate 1, the sealing plate 6 is a circular plate, a first through hole 8 is formed in the center of the sealing plate 6, the channel plate 1 is a circular column, a second through hole 9 is formed in the center of the channel plate 1, and the first through hole 8 and the second through hole 9 are communicated to form the connecting channel 2. The diameter of the sealing plate 6 is not more than the inner diameter of the inner cylinder body 4, the sealing plate 6 is arranged in the cavity of the inner cylinder body 4, the diameter of the sealing plate 6 is simultaneously larger than that of the channel plate 1, the sealing plate 6 is connected with the channel plate 1, the cross section is T-shaped, and the channel plate 1 is arranged in the ignition powder cavity 3.

This embodiment can be with

effect medicine chamber

5 and 3 intercommunications in the medicine chamber of igniting through setting up passageway board 1 on interface channel 2, and the back is lighted to the propellant powder in the medicine chamber of igniting 3, and burning flame and pressure pass through interface channel 2 and get into effect medicine chamber 5, have replaced traditional lead wire, avoid damaging because of the lead wire is not hard up to lead to the fireworks.

Preferably, as shown in fig. 3, the vertical distance between the end surface of the channel plate 1 far from the sealing plate 6 and the end surface of the ignition powder chamber 3 is H. In particular, the distance H is greater than 1 mm. The ignition powder placing amount in the ignition powder cavity 3 can be conveniently adjusted, the ignition powder is arranged at the position, the required time for the height of the firework outer barrel for spraying the firework inner barrel to reach the highest point is calculated, and the required dosage of the ignition powder is increased or decreased, so that the ignition and combustion time is controlled, the effect powder in the inner barrel is just ignited when the firework inner barrel is sprayed to the highest point by the firework outer barrel, and the ignition effect is generated; the ignition powder is adopted to control the ignition powder, the ignition powder is more convenient and efficient than lead control, and the possibility of misfiring caused by poor high-altitude over-firing of the lead can be avoided.

Specifically, as shown in fig. 3, the connecting channel 2 is in a truncated cone shape, the large circular surface of the connecting channel 2 is close to the effective medicine cavity 5, and the small circular surface of the connecting channel 2 is close to the ignition medicine cavity 3.

After mixing paper pulp and limestone, through mould integrated into one piece, labour saving and time saving has replaced traditional paper paste barrel, and manual operation processes such as clay sculpture seal can arrange production according to plan rationally, needn't rely on weather factor, influence the production progress. When the explosive in the effect explosive cavity 5 is ignited and the inner barrel body 4 is exploded, the exploded fragments are uniform, the various effect explosives such as the bright beads in the effect explosive cavity 5 are uniformly combusted, various firework patterns can be realized, and the firework bursting effect is good.

As shown in fig. 4, a firework structure comprises an outer box 12, a plurality of rows of firework setting off cylinders 11 are arranged in the outer box 12, a main firework ignition fuse 13 is further arranged outside the outer box 12, the firework setting off cylinders 11 comprise firework inner cylinders as shown in fig. 1 and firework outer cylinders arranged outside the firework inner cylinders, openings of the firework inner cylinders are upwards sleeved in the firework outer cylinders, and one firework inner cylinder is sleeved in one firework outer cylinder in a normal condition. The bottom of the firework outer barrel is provided with bottom mud, a black gunpowder layer is arranged above the bottom mud, one end of the black gunpowder layer is connected and arranged on the ignition fuse of the setting-off barrel, the other end of the black gunpowder layer is provided with a fire transfer fuse, the ignition fuse of the setting-off barrel and the fire transfer fuse are both led to the periphery of the firework outer barrel, and a firework inner barrel is arranged above the black gunpowder layer.

The working process of the embodiment is as follows:

after the section of thick bamboo that sets off ignition is ignited, the burning is spread to black powder layer, and black powder layer explodes and splits, and the propellant powder drives the fireworks inner tube and rises aloft, waits that the propellant powder burns completely, and flame gets into effect medicine chamber 5, and the effect medicine burning is opened the package medicine and is exploded the fireworks inner tube, produces the loud sound, and the bright pearl is equivalent to the fruit medicine simultaneously, sends the light of colorful riotous profusion.

The effect medicine is various chemicals, and can dye flame when burning. For example, when copper burns, the flame becomes green; when strontium nitrate and strontium carbonate are burnt, the flame can turn into red; the flame is yellow when the sodium nitrate and the sodium oxalate are combusted; strontium nitrate and sodium nitrate are mixed in certain proportion and the flame is orange red when burning. The luminous effect is a main effect of firework effect agents, and no matter the firework effect agents are lighting agents capable of playing a role in lighting or agents capable of generating bright stars, the firework effect agents capable of generating a flash effect and a extinguishment effect can not be distinguished from the firework effect generated by the firework effect agents. The luminous effect makes the fireworks capable of emitting colorful light when burning.

Utility model has the advantages and positive effect be:

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
