Abstract

A kind of firecrackers with continuous sound is made up of paper or plastic through printing the firecracker powder on main body by silk screen printing method to form any curve and arc, and when the firecracker powder is ignited, the firecracker powder will flash, explode and disappear repeatedly when it reaches a certain temp.

Description

Printing fire crackers giving continuous sound

The utility model relates to a kind of firecrackers, particularly relates to a kind of printing firecrackers with continuous sound.

Chinese pay attention to especially for festival celebration, especially in festival celebrations such as the Lantern Festival, the Mid-autumn Festival, New Year, lively especially especially, and generally come temporarily in order to increase exciting atmosphere in festival celebration, be to reach sound, light all effects of holding concurrently mostly with the pyrotechnics of setting off firecrackers, burn, and firecrackers in the past are because have the shortcoming of exploding and flying to scurry everywhere, so be easy to cause the danger that injures other people and firing combustibles.

Main purpose of the present utility model is to provide a kind of printing firecrackers with continuous sound, it mainly is in the mode of serigraphy black powder and effect medicine to be printed on the body that the scraps of paper, sheet make, and can reach the effect of continuous sound and flicker light when lighting.

A kind of printing firecrackers provided by the utility model with continuous sound, it is in the mode of serigraphy on the body of suitable size, effect medicine and two kinds of firecrackers medicaments of black powder are printed on the appropriate location of body, and form the change of shape of arbitrary curve, radian, when lighting effect medicine and black powder, make the black powder continuity light the effect medicine, can on body, be when making the effect medicine meet heat arrival uniform temperature and emit light and heat repeatedly and disappear, thereby form the firecrackers that have continuous sound and glisten and change.

Below by preferred embodiment and accompanying drawing the printing firecrackers with continuous sound of the present utility model are elaborated, in the accompanying drawing:

Fig. 1 is the schematic perspective view of the utility model preferred embodiment;

Fig. 2 is the generalized section of the utility model preferred embodiment;

Fig. 3 is the generalized section of another preferred embodiment of the utility model;

Fig. 4 is the generalized section of another preferred embodiment of the utility model;

Fig. 5 is the schematic perspective view of another preferred embodiment of the utility model;

Fig. 6 is the schematic perspective view of another preferred embodiment of the utility model.

Please cooperate and consult shown in Fig. 1,2, the printing firecrackers with continuous sound of the present utility model, it includes the black powder 20 of body 10, reservation shape and the members such as effect medicine 30 of reservation shape; Wherein:

Body 10 is to make the thin type lamellar body with paper or plastic cement, and be that mode with serigraphy is printed on black powder 20 or effect medicine 30 on the body 10, as shown in Figure 1, 2, be black powder 20 printings to be after the swirl shape earlier, utilize serigraphy just effect medicine 30 can not to be printed on black powder 20 tops deviation position, the printing area of black powder 20 is greater than effect medicine 30.

The composition of above-mentioned black powder 20 is to contain potassium nitrate 75%, sulphur 10%, carbon dust 15% or potassium perchlorate 75%, carbon dust 25%; And the composition of effect 30 is to contain alloy 15-25%, aluminium powder 0-5%, metal oxide 70-80(such as lead orthoplumbate, manganese dioxide, lead peroxide etc.) adhesive 3.5-5%(such as nitrocotton, dextrin, glutinous rice flour etc.) and solvent (look viscosity and determine); Therefore, when lighting black powder 20 and effect medicine 30, effect medicine 30 is lighted as metallurgy action, utilizes almag (MgAl) substituted metal oxide wherein to make precipitating metal, and alloy also is reacted into magnesia (Mg) simultaneously), aluminium oxide (Al ₂O ₃), its process is exothermic reaction, alloy can produce vibration when separating, send explosion simultaneously, because be exothermic reaction and make explosion that continuity be arranged, black powder 20 then can continue the combustion efficiency of effect medicine 30, when effect medicine 30 arrives uniform temperature and disappearance immediately after burning, and after the disappearance appropriate time, the gunpowder 20 of taking advantage of darkness again to be reaching predetermined temperature, and the burning of repetitiousness ground is luminous, disappear to produce detonation, flash effect.

So, shown in Fig. 3,4, be the other two kinds of group modes of black powder of the present utility model and effect medicine, it among Fig. 3 the dual-side that black powder 208 and effect medicine 308 is printed on body 108 respectively, when lighting black powder 208, because the thickness of body 108 is quite thin, so the fire that black powder 208 produced can penetrate body 108 and light effect medicine 308; And shown in Figure 4, then be that black powder 207 and effect medicine 307 are molded on the opposite face of two bodies 107 with screen printing mode respectively, then that the opposite face of black powder 207 and effect medicine 307 is bonding to pasting mutually with viscose glue, also can be made into the firecrackers of continuous sound.

Again as shown in Figure 5, be that black powder 203 and effect medicine 303 in turn are formed on the body 103 with screen printing mode, and viscose glue peelable and that can repeat to paste is set between black powder 203(or effect medicine 303 and body 103, just can paste, be combined into arbitrary shape, curvilinear motion voluntarily on another scraps of paper, sheet, after lighting, have more the flash of light variation in moulding.

For ease of lighting of above-mentioned black powder, can partly make straw line at black powder and draw (not showing on the figure), and be extended with suitable length, just can light easily.

And for example shown in Figure 6, be that first black powder 205 and viscose glue are coated on the body 105, and body 105 circle is rolled into cylindric, and the lead-in wire 405 that will be coated with effect medicine 305 is placed on and is body cylindraceous 105 inside, can make lead-in wire 405 fixing by the effect of viscose glue.

In sum, the simple structure of this case embodiment, easy to manufacture, and the safe entertainment effects such as flash of light, continuous sound that can reach again; So the utility model is very practical really.

Claims

1, a kind of printing firecrackers with continuous sound is characterized in that, two kinds of firecrackers medicaments of effect medicine and black powder are set on its body, and form random shape variations.

According to the printing firecrackers of claim 1, it is characterized in that 2, body is the scraps of paper or sheet.
