Abstract
The utility model relates to an inflatable firecracker, which relates to the gas detonation sound, and in particular relates to the simulated firecracker sound. The firecracker influences the air quality and leads to the risks such as fire, personal injury, building collapse and the like. In order to overcome the defects caused by the gunpowder firecracker, the utility model designs an inflatable firecracker. The technical scheme adopted in the utility model is as follows: an inflatable device is connected to an inflatable pipe, the inflatable pipe is used for inflating an air pipe, and the air pipe is used for charging the air into a barrel of a firecracker pipe; the air pipe is in thread connection with the firecracker pipe; a spring is connected with a sealing cover and a bottom cover; the bottom cover is bonded with a rubber washer, and the bottom cover is soft magnetic stainless steel; and the other end of the firecracker pipe is fixedly provided with 3 to 8 magnetic buttons, the magnetic buttons and the stainless steel bottom cover as well as the rubber washer seal the other end of the firecracker pipe. The inflatable firecracker has the beneficial effects that no fire risk exists, no building is damaged, and no transportation risk exists; the resource can be saved; and the inflatable firecracker can be used as a children toy.
Description
Technical field
The present invention relates to the gas explosion, particularly simulate the firecracker sounding.
Background technology
On New Year's Day or other festivals, it is celebrating lively that the people like, like setting off firecrackers, but the concentrated short time of firecracker sets off, the deterioration that the smell of firecracker and the powder of firecracker bring air quality, the urban air-quality that this has been worsened is brought and is made the matter worse, and increases the weight of the city haze and increases the risk of breathing problem, and the health of human body is come to harm; The setting off of firecracker also may be brought fire, personal injury, the building equivalent risk that collapses; Firecracker is long at Chinese history, gunpowder is one of four invents by China, but Chinese utilize gunpowder to make firecracker, and Englishman etc. utilize gunpowder to make firearms plunder China wealth, this history can not be forgotten, the too much burning of firecracker can only be to endanger the realm to hinder the people, is a kind of waste of social resources.
Summary of the invention
For overcoming the deficiency that the gunpowder firecracker brings, the present invention designs a kind of inflatable firecracker.
The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of inflatable firecracker, form by tracheae, firecracker pipe, gas tube, and it is characterized in that: the firecracker pipe is made up of seal cover, air-filled pore, cylinder, spring, screw thread, bottom; An aerating device (can be foot-operated pump-up device) is connected to gas tube, and gas tube is inflated tracheae, and tracheae is inflated the cylinder of firecracker pipe by the air-filled pore of seal cover; Tracheae has protuberance, protuberance that external screw thread is arranged, firecracker Guan Yiduan has internal thread, the internal thread bottom diameter of firecracker pipe diminishes, form a platform, sealing elastic packing ring is arranged at the seal cover bottom, and tracheae and firecracker pipe are by being threaded, and the seal washer contact platform of seal cover is with the firecracker seal of tube, the other end of firecracker pipe is fixed with 3-8 magnetic clasp, and the magnetic clasp surface is concordant with firecracker pipe end face; A spring connects seal cover and bottom; The other end end face that bottom is stained with elastic packing ring or firecracker pipe adheres to the elastic packing ring, and bottom is the stainless steel of soft magnetism; Magnetic clasp and stainless steel bottom and elastic packing ring seal the firecracker pipe other end.
Tracheae and firecracker pipe preferred material are hard metal, such as aluminium alloy or stainless steel.
The invention has the beneficial effects as follows: device is simple, and is with low cost; Device can recycle, and saves social resources; Can produce the firecracker sound, not produce any pollutant; Do not have fire risk, can not damage building, do not have risk in transit; Can be used as toy for children uses.

Wherein, 1, tracheae, 2, the firecracker pipe, 3, gas tube, 4, seal cover, 5, air-filled pore, 6, spring, 7, screw thread, 8, bottom.
The specific embodiment
An aerating device is connected to gas tube 3,1 inflation of 3 pairs of tracheaes of gas tube, tracheae 1 is by 2 inflations of 5 pairs of firecracker pipes of air-filled pore, and more than 1 of tracheaes have protuberance, protuberance that external screw thread is arranged, firecracker Guan Yiduan has internal thread 7, internal thread 7 bottom diameters diminish, and form a platform, and sealing elastic packing ring is arranged at seal cover 4 bottoms, seal washer contact platform is with the firecracker seal of tube, seal cover 4 is connected to bottom 8 by spring 6, and bottom is stained with the elastic packing ring, and bottom is the stainless steel of soft magnetism; The other end of firecracker pipe is fixed with 3-8 magnetic clasp, and magnetic clasp and stainless steel bottom and rubber washer are with the firecracker seal of tube.
Using method is: when initial, firecracker pipe 2 is sealed at both ends, and aerating device is by 1 inflation of 3 pairs of tracheaes of gas tube, tracheae is by 5 pairs of firecracker pipe inflations of air-filled pore, and along with increasing of air pressure, the pressure that acts on bottom increases, active force strengthens, and overcomes magnetic field force, and bottom 8 is opened, air-flow is gone out, and sends explosion, and the inside and outside differential pressure of seal cover 4 increases simultaneously, seal cover 4 contact platforms are with the firecracker seal of tube, spring 6 retracts bottom 8, with the other end sealing of firecracker pipe, finishes once inflation and detonation.As long as each firecracker pipe internal volume is designed to have slightly the magnetic field size of difference or magnetic clasp to have the size of difference or air-filled pore that difference is arranged slightly slightly, just can realize the sounding gradually of firecracker, if continue inflation, constantly sounding.
Claims (1)
