Abstract

An air firecracker is formed by parallelly connecting a plurality of air cannons on an air pipe, an air tap is arranged at one end of the air pipe, a one-way valve is arranged in the air tap, a safety valve is arranged at the other end of the air pipe, and an air escape cock is further arranged on the air pipe. Each air cannon is formed by connecting a fixing seat with a sealing sleeve through a connecting column, a slide sleeve is arranged on each sealing sleeve, a stopper is arranged below each slide sleeve, an internal space of each sealing sleeve is divided into an upper air chamber and a lower air chamber, each connecting column is of a hollow structure, an air vent hole is arranged at the position of each upper air chamber, a damping hole is arranged at the position of each lower air chamber, and an explosion opening is arranged at the tail end of the lower air chamber of each sealing sleeve. Sounds similar to those of firecrackers are made by the aid of pressure difference of air, the air firecracker is similar to an explosive firecracker acoustically and visually, environmental pollution and fire can be avoided while personnel risks cannot be caused as air is produced during explosion, a reel of air firecrackers can be recycled for many times, and energy saving, environmental protection and safety are really achieved.

Description

A kind of air firecrackers

Technical field

The present invention relates to replace a kind of sound device of traditional gunpowder firecrackers.

Background technology

For should with solemn, grand, exciting atmosphere, the affairs that are absolutely necessary of setting off firecracker at present, mostly are traditional explosive firecrackers on the market, not only contaminated environment, and danger.A large amount of explosives are deposited in together when producing, in case the harm that blast produces is very huge, serious environment pollution not only when setting off, also might wound the people and produce fire, because traditional firecrackers are expendable consumed product, can not reuse, also cause the waste of resource, have a lot of cities to forbid setting off of explosive firecrackers.

Summary of the invention

The objective of the invention is to solve the defective in the above-mentioned technology, provide a kind of safe, and can reusable air firecrackers

For achieving the above object, the present invention is by the following technical solutions: a kind of air firecrackers, by on a tracheae and be connected to a plurality of air bubbles and form, be provided with valve at tracheae one end, and in valve, be provided with check valve, be provided with safety valve at the tracheae other end, on tracheae, also be provided with air escape cock.

Described air bubble is to be connected to form by a joint pin by holder and sealing shroud, be provided with sliding sleeve at sealing shroud, sliding sleeve is arranged with and stops soon, be two air chambers up and down with spatial separation in the sealing shroud, described joint pin is hollow structure, have passage at upper air chamber position, have damping hole at lower air chamber position, have blast mouthful at the lower air chamber end of sealing shroud.

Pressure-air enters the upper chamber of air firecrackers through valve, and there is a small amount of pressure-air to enter lower chamber through damping hole, the pressure reduction of upper lower chamber is pushed sliding sleeve to lower chamber, a mouthful good seal will explode, finally reach the pressure balance of lower chamber, and all be full of pressure-air, when pressure reaches setting value, safety valve is opened, and stops inflation this moment.Press air escape cock, the gas of upper chamber is discharged rapidly, and it is slow that the gas of lower chamber is discharged, and this moment, pressure reduction was pushed sliding sleeve open, and the gases at high pressure of lower chamber are discharged from the blast mouth, send explosive sound.The air firecrackers string that capacity is different is received and just has been assembled into together dish firecrackers, and capacity is different, and the sound of blast varies, seted off once after again inflation can also continue to set off.

Beneficial effect of the present invention is: utilize the pressure differential of air to cause sound to send the sound of similar firecrackers, at the sense of hearing and similar explosive firecrackers visually, because what explosion time produced is air, so do not pollute the environment and produce fire, pressure setting can be to personnel's cause danger under safety value yet, one dish firecrackers can be many times recycling, really accomplish energy-saving environmental protection safety, but also can pass on the traditional culture of China, make traditional culture obtain continuity and development.

Description of drawings

Fig. 1 is the section of structures of a kind of air firecrackers of the present invention take one group of firecrackers as embodiment.

The specific embodiment

As shown in Figure 1, a kind of air firecrackers are by on a tracheae 1 and be connected to a plurality of air bubbles 2 and form, be provided with valve 3 at tracheae 1 one ends, and in valve 3, be provided with check valve 31, and be provided with safety valve 4 at tracheae 1 other end, on tracheae, also be provided with air escape cock 5.

Air bubble 2 is to be connected to form by a joint pin 23 by holder 21 and sealing shroud 22, be provided with sliding sleeve 24 at sealing shroud 22, sliding sleeve 24 is arranged with and stops fast 25, be two air chambers up and down with sealing shroud 22 interior spatial separations, described joint pin 23 is hollow structure, have passage 27 at upper air chamber 26 positions, have damping hole 29 at lower air chamber 28 positions, have blast mouthfuls 30 at lower air chamber 28 ends of sealing shroud 22.

In Fig. 1, gases at high pressure enter tracheae 1 the inside by valve 3, and valve 3 is check valve, can only air inlet can not give vent to anger, gas enters upper chamber 26 the insides through pore 27, has simultaneously a small amount of gas to enter lower chamber 28 the insides through damping hole 29, air-chamber differential pressure is pressed to lower chamber 28 with sliding sleeve 24 up and down, the mouth 30 that will explode seals, and when gas pressure reached certain value, safety valve 4 was opened, stop inflation this moment, finally reach up and down gas chamber pressure balance, sliding sleeve 24 remains static, and so far finishes gas replenishment process.

When pressing air escape cock 5, the gases at high pressure of upper chamber 26 flow out fast through passage 27 and tracheae 1, pressure is less than the pressure of lower chamber 28, the pressure reduction of upper lower chamber is pushed sliding sleeve to holder 21 directions, the gases at high pressure of lower chamber discharge through blast mouth 30, produce explosive sound, finish blast process this moment.

Inflation can be taked the air compressor machine inflation, also can take the inflator inflation.If damping hole impact sealing and blast process, explosive effect is undesirable at the trial, can add at the damping hole place check valve, pressure-air can only flow to lower chamber, and the gas of lower chamber can't flow to upper chamber, sliding sleeve is pressed on the lower chamber in the time of so both can guaranteeing to inflate, and upper lower chamber has pressure differential and makes the sliding sleeve motion produce sound in the time of can guaranteeing to light a fire again, and just cost can increase a little.The contact portion of upper lower chamber adds the very high fineness of needs in man-hour, not so can affect sealing effectiveness, also can add at the upper surface place of lower chamber a sealing ring, can improve sealing effectiveness like this.

What adopt between valve, safety valve air firecrackers and the tracheae is to be threaded, the a plurality of air firecrackers strings that vary in size are connected on the tracheae, dish firecrackers have just been formed, tracheae also can be connected in series, so the length of firecrackers can be regulated, be filled with the air of different pressures, the explosive sound that firecrackers send is just different, so the size of sound also can be regulated.If there are firecrackers to break, it can be screwed down, change newly, perhaps mouth is blocked, do not affect the work of other firecrackers.
