Description
Technical field
The utility model relates to a kind of without pyrotechnics firecrackers.
Background technology
The firecrackers of existing generation pyrotechnics, when setting off, fire and personal injury accident, and, produce a large amount of smog, contaminated environment; The transportation of firecrackers is also very easily blasted and fire; In addition, a lot of regional No Fireworks, in the festive occasion, has lacked festive air.
Summary of the invention
The purpose of this utility model is the problems referred to above in order to solve the firecrackers existence producing pyrotechnics, and provides a kind of without pyrotechnics firecrackers.
The utility model includes air pump, tracheae and gas type firecrackers, and tracheae is communicated with between air pump and gas type firecrackers, and be provided with non-return valve in tracheae, compressed air can only flow along tracheae to gas type firecrackers, can not reverse flow; Described gas type firecrackers are made up of gun barrel and several single big guns, several single big guns are laid in gun barrel surface and are communicated with gun barrel inside, single big gun keeps off pad by gun tube, rubber cushion, rupture disk, clamp nut and elasticity to form, rubber cushion is placed in the head end of gun tube, rupture disk is positioned at outside rubber cushion, and clamp nut is screwed onto the head end of gun tube, and rupture disk and rubber cushion are closely fixed on the outer end of gun tube by clamp nut, rubber cushion has been the effect of sealing, and the inner of gun tube is provided with elasticity gear pad.
The thickness of described rupture disk is different.
Described air pump is hand air pump or electric air pump.
Single big gun of described gas type firecrackers can be made up of gun tube and rupture disk, and rupture disk is bonded in gun tube outer end, and tracheae and gas type firecrackers are detachable connection, and after gas type firecrackers use, gas type firecrackers entirety abandons, the gas type firecrackers more renewed.
Described gas type firecrackers can be single big gun structure, and single big gun is directly communicated with tracheae.
The course of work of the present utility model and principle:
Air pump is by tracheae to the inflation of gas type firecrackers, and compressed air can only flow along tracheae to gas type firecrackers, can not reverse flow; After the big gun overpressure of single big gun is greater than the ultimate resistant of rupture disk, rupture disk explosion, send the sound like firecrackers, after the rupture disk explosion of this single big gun, the gas flowed outside this single big gun pushes elasticity gear pad the import department of gun tube to, and then this gun tube is sealed up, prevent the pressure in gun barrel from reducing.Because the thickness of rupture disk is different, so the sound is interval, it not explosion together.One take turns the whole explosion of rupture disk after, dismounting clamp nut, again change rupture disk, can setting off firecrackers of next round be carried out.
The beneficial effects of the utility model: transport and use safety; Use in the area of Fireworks Prohibited, can festive air be increased.

Detailed description of the invention
Refer to shown in Fig. 1, for the first embodiment of the present utility model, it includes air pump 1, tracheae 2 and gas type firecrackers 3, tracheae 2 is communicated with between air pump 1 and gas type firecrackers 3, non-return valve 4 is provided with in tracheae 2, compressed air can only flow along tracheae 2 to gas type firecrackers 3, can not reverse flow, described gas type firecrackers 3 are made up of gun barrel 31 and several single big guns 32, several single big guns 32 are laid in gun barrel 31 surface and are communicated with gun barrel 31 inside, as shown in Figure 2, single big gun 32 is by gun tube 321, rubber cushion 322, rupture disk 323, clamp nut 324 and elasticity gear pad 325 are formed, rubber cushion 322 is placed in the head end of gun tube 321, rupture disk 323 is positioned at outside rubber cushion 322, clamp nut 324 is screwed onto the head end of gun tube 321, rupture disk 323 and rubber cushion 322 are closely fixed on the outer end of gun tube 321 by clamp nut 324, rubber cushion 322 has been effects of sealing, the inner of gun tube 321 is provided with elasticity gear pad 325.
The thickness of described rupture disk 323 is different.
Described air pump 1 is hand air pump or electric air pump.
As shown in Figure 3, for the second embodiment of the present utility model, it includes air pump 1, tracheae 2 and gas type firecrackers 3, tracheae 2 is communicated with between air pump 1 and gas type firecrackers 3, and single big gun 32 of described gas type firecrackers 3 is made up of gun tube 321 and rupture disk 323, and rupture disk 323 is bonded in gun tube 321 outer end, tracheae 2 connects for detachable with gas type firecrackers 3, after gas type firecrackers 3 use, gas type firecrackers 3 entirety abandons, the gas type firecrackers 3 more renewed.
As shown in Figure 4, be the 3rd embodiment of the present utility model, it includes air pump 1, tracheae 2 and gas type firecrackers 3, and described gas type firecrackers 3 are single big gun 32 structure, and single big gun 32 is directly communicated with tracheae 2.
The course of work of the present embodiment and principle:
Air pump 1 is inflated to gas type firecrackers 3 by tracheae 2, and compressed air can only flow along tracheae 2 to gas type firecrackers 3, can not reverse flow; After in the gun tube 321 of single big gun 32, pressure is greater than the ultimate resistant of rupture disk 323, rupture disk 323 explosion, send the sound like firecrackers, after rupture disk 323 explosion of this single big gun 32, outside this single big gun 32, elasticity is kept off the import department that gun tube 321 pushed to by pad 325 by the gas of flowing, and then this gun tube 321 is sealed up, prevent the pressure in gun barrel 31 from reducing.Because the thickness of rupture disk 323 is different, so the sound is interval, it not explosion together.One takes turns rupture disk 323 all after explosion, and dismounting clamp nut 324, again changes rupture disk 323, can carry out setting off firecrackers of next round.
