Abstract

A simulative fireworks-displaying shell features that broken coloured paper is loaded in a sylindrical shell with two sealing end covers. The shell is loaded in magazine case of launcher. When high-pressure air valve is opened, the end cover and broken coloured paper are pushed from sylindrical shell into launching tube, where they are accelerated and finally proejcted into sky by high-speed airflow. The slowly dropping broken coloured paper looks like the patterned light of fireworks display, the sound generated when end cover is opened simulate its sound and the water vapour in air is condensed by low temp caused by expansion of high-speed gas to form fog which simulates its smoke.

Description

Simulated fireworks display

The present invention relates to a kind of simulated fireworks display.The simulated fireworks display that uses in occasions such as wedding, celebration, opening, red-letter days particularly.

Traditional fireworks display adopt gunpowder as cast charge, and shortcoming is contaminated air, inflammable and explosive, fire hazardous, dangerous.For this reason, many countries and city No Fireworks.

The objective of the invention is to propose a kind of novel safe display shell, perhaps be referred to as simulated fireworks display, this display shell uses the emission of special-purpose emitter can simulate the effect that realizes traditional fireworks display, overcomes the shortcoming of traditional fireworks display simultaneously, does not fire not quick-fried, contaminated air not.

The objective of the invention is to realize by following technological means: it is colored the shredded paper made from the fragment of frivolous materials such as colored paper, plastic sheeting, metal forming to be housed at one in paper, plastics or metal cylindrical shell, there is seal closure at the two ends of cylindrical shell, this seal closure can be paper plug, cork or foam plug, be bonded at the paper of oral area or the film of plastics or metal, the plastics that are enclosed within oral area or paper lid, its effect is to prevent that the shredded paper gondola water faucet from going out and can be washed open by gases at high pressure, simultaneously, this seal closure should be light hurting sb.'s feelings after avoiding it to fly out.

The isolated plant of launching this display shell comprises a magazine, to hold display shell, the transmitting tube that the magazine front end has a cylindrical shell shape with display shell to adapt, be meant that generally both internal diameters are identical, the magazine rear end is connected with high-pressure air source by valve, and it is openable so that put into display shell that magazine has an end at least.

Its course of work is: display shell is contained in the magazine of emitter, when connecting the valve open of high-pressure air source, transmitting tube is gone out and rushed in to gases at high pressure with seal closure in the display shell and shredded paper flower from cylindrical shell, the shredded paper flower is accelerated the ejection of last high speed in transmitting tube, subsequently Pen Chu air-flow with its blow higher.Spraying to aerial shredded paper spends and slowly falls the flame of having simulated fireworks display; Send when washing seal closure open " bang " sound and " puff " acoustic simulation of sending subsequently the sound of fireworks display; Gases at high pressure expand at a high speed and cause temperature drop, make airborne water vapour coagulate mist after the cryogenic gas ejection, have simulated the smog of fireworks display.

Describe the present invention in detail below in conjunction with accompanying drawing.

Self-evident, accompanying drawing is in order to illustrate rather than limit the present invention.Equally, under the prerequisite that does not influence the understanding of the present invention, adopt simplified painting to avoid drawing too numerous and diverse.

Figure 1 shows that structure of the present invention and working state schematic representation.

Among Fig. 1, shredded paper flower (2) is housed in the cylindrical shell (1), there are seal closure (3) and (4) in two ends, and among this figure, seal closure is to cover and be bonded on the cylindrical shell (1) with the film seal that paper, plastic sheeting or metal forming are made, and this just constitutes a display shell.The isolated plant of launching this display shell comprises a magazine (5) that holds display shell, magazine (5) front end has a transmitting tube (6) that adapts with cylindrical shell (1) shape, both internal diameters are identical, the bonnet (7) of magazine (5) can be opened so that put into display shell, is hinged between the two, and (9) are tension hooks, also can otherwise connect between the two, as be threaded, bolt connection, socket etc., have air intake duct (8) to be connected with high-pressure air source on the magazine bonnet (7) by valve.Its course of work is: display shell is contained in the magazine (5) of emitter, when connecting the valve open of high-pressure air source, transmitting tube (6) is gone out and rushed in to gases at high pressure with the seal closure in the display shell (3) and (4) and shredded paper flower (2) from cylindrical shell (1), shredded paper flower (2) is accelerated last high speed ejection in transmitting tube (6), subsequently Pen Chu air-flow with its blow higher.Spraying to aerial shredded paper spends and slowly falls the flame of having simulated fireworks display; Send when washing seal closure open " bang " sound and " puff " acoustic simulation of sending subsequently the sound of fireworks display; Gas expands at a high speed and causes temperature drop, makes airborne water vapour coagulate mist after the cryogenic gas ejection, has simulated the smog of fireworks display.

Further describe the present invention below in conjunction with embodiment.

Figure 2 shows that the schematic diagram of a kind of structure of the present invention.

Among Fig. 2, shredded paper flower (2) is housed in the cylindrical shell (1), there are seal closure (3) and (4) in two ends, and in this example, seal closure (3) or (4) are the stoppers made from light materials such as foamed plastics or corks.

Figure 3 shows that the schematic diagram of a kind of structure of the present invention.

Among Fig. 3, shredded paper flower (2) is housed in the cylindrical shell (1), there are seal closure (3) and (4) in two ends, and in this example, seal closure (3) or (4) are the stoppers of thin-walled hollow structure.

Figure 4 shows that the schematic diagram of a kind of structure of the present invention.

Among Fig. 4, shredded paper flower (2) is housed in the cylindrical shell (1), there are seal closure (3) and (4) in two ends, and in this example, seal closure (3) or (4) are the stoppers of thin-walled cup-shaped structure.

Figure 5 shows that the schematic diagram of a kind of structure of the present invention.

Among Fig. 5, in cylindrical shell (1), there is one to roll the secondary tube (10) that forms with elastic sheets such as paper, plastics, and locate not do any fixing at interface (11), promptly secondary tube (10) will lean on the elasticity of self to launch when losing constraint, cup-shaped seal closure (3) and (4) are enclosed within the outside at secondary tube (10) two ends, and shredded paper flower (2) is contained in the inside.During emission, preceding seal closure (4) and back seal closure (3) are enclosed within secondary tube (10) outside and are injected in the air by integral body, because it is any fixing that secondary tube (10) is located not do at interface (11), and the seal closure at two ends only is a unsettled constraint, so secondary tube (10) elasticity by self when flight begins to launch until deviating from from the seal closure at two ends from the centre of interface (11), and launch fully, the shredded paper flower is discharged, display shell when flight roll and the resistance of air all helps finishing of this process.Adopt this structure to penetrate the shredded paper flower higher.
