BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the structure of a firing unit. DETAILED DESCRIPTION

[0016] Referring to the attached drawings, a specific structure of the present invention is shown. The smoke fireworks suitable for nighttime display in the example are composed of ten first launch outer tubes 1 forming a white flash tube row 2, and ten second launch outer tubes 4 forming a color smoke tube row 3. The white flash tube row 2 and the color smoke tube row 3 arranged in parallel in front and back form a display unit. The smoke fireworks of the present invention include at least one display unit. In other embodiments, multiple display units may be superimposed. The number of launch outer tubes in each tube row may also be set accordingly as needed.

[0017] Each launch outer tube is filled with launch charge and an effect inner tube, and the effect inner tube is filled with corresponding effect charge, and the effect charge and the launch charge are connected by a fire fuse. These belong to the general fireworks assembly technology and will not be described in detail.

[0018] In the example, the height of the first emitting outer tube 1 of the white flash tube row 2 is 30 cm (centimeter), and the height of the second emitting outer tube 4 of the colored smoke tube row 3 is 25 cm.

[0019] In the example, the amount of propellant charged in the first launching outer tube 1 is 6 g (grams), and the amount of propellant charged in the second launching outer tube 4 is 4 g.

[0020] In the example, in the first launching outer tube 1, the fuse delay time of the overfire fuse that realizes the ignition connection between the effect medicine and the launching medicine is 70S (seconds), and the fuse delay time of the overfire fuse in the second launching outer tube 4 is 35S.

[0021] In the example, the composition and weight ratio of the effect medicine in the effect inner cylinder of the first emission outer cylinder 1 are 60 barium nitrate, 30 special alloy, 8 sulfur, 7 potassium nitrate, 5 bismuth oxide, and 4 binder. Mix uniformly, granulate, dry, and fill into the effect inner cylinder according to the general method.

[0022] In the example, the effect medicine in the effect inner tube of the second emission outer tube 4 has a colored smoke agent as the core, and the core is wrapped with an outer medicine:

[0023] The components and weight ratio of the outer packaged powder are 70g of military powder (i.e. black powder), 11g of high potassium, 10g of alloy, 8g of resin, and 10g of aluminum powder.

[0024] The colored smoke agent of each effect inner tube can be selected from red smoke agent, blue smoke agent or yellow smoke agent, and the number of effect inner tubes of various colors can be selected and configured according to the design of the smoke fireworks. The components and weight ratio of the colored smoke agent are:

[0025] Red smoke agent: 23g potassium chlorate, 16g flour, 6g sulfur, 8g chloride ion, 45g smoke red, 6g resin, 10g single base powder;

[0026] Blue smoke agent: phthalocyanine blue 56g, white sugar 21g, potassium chlorate 23g;

[0027] Yellow smoke agent: 24g potassium chlorate, 16g flour, 6g sulfur, 8g chloride ion, 34g smoke yellow, 6g resin, 9g single base powder.

[0028] The color smoke agent is mixed evenly according to the general method, granulated, and dried to obtain the core; the outer package medicine is mixed evenly according to the general method, a moistening amount of solvent (such as alcohol) is added, and it is put into a drum together with the core to rotate so that the outer package medicine is evenly wrapped on the core, dried, and the effect medicine is loaded into the effect inner cylinder. In the effect medicine, the outer package medicine can make the consolidated particles formed in the initial stage of aluminum powder combustion form a temporary solid shell, and the shell wraps the color smoke agent core, so that the color smoke agent is heated and sublimated without burning and smokes, and the smoke overflows from the gaps between the consolidated particles of the shell, forming a color smoke strip during the lifting process until the entire effect medicine is burned out.

[0029] The basic working principle of the present invention is: after the effect inner tube of the white flash tube row 2 is lifted into the air and ignited, the effect medicine emits combustion and explosion light from the effect inner tube; after the effect inner tube of the colored smoke tube row 3 is lifted into the air and ignited, the effect medicine emits smoke shapes from the effect inner tube. The smoke shapes located below are illuminated by the light emission so that they can be appreciated by the audience on the ground. To this end, it is necessary to achieve precise coordination between the instantaneous light emission of the white flash and the gas dynamic smoke screen composed of various colored smoke strips. The present invention coordinates the specific white flash and smoke medicine combination with the colored smoke effect structure, and comprehensively utilizes the above-mentioned height ratio, time ratio, medicine amount ratio and other adjustment means to coordinate and accurately control the timing coordination of the fire connection and explosion of the white flash tube row and the colored smoke tube row and the coordination of the elevation of the combustion and explosion points.

[0030] Experimental visual observation proves that the smoke fireworks using the above technical solution can illuminate the colored smoke from top to bottom, so that observers on the ground can fully appreciate the entire gorgeous smoke screen composed of various colored smoke strips; and the white flash does not affect the burning effect of the colored smoke, such as the explosion of the white flash effect powder will not cause disturbance and damage to the smoke screen, ensuring the perfect presentation of the colored smoke effect. Therefore, it is suitable for nighttime setting off.

[0031] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and describes these embodiments in detail in conjunction with the accompanying drawings in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
