Detailed Description
In order to describe the technical content, the constructional features, the achieved objects and effects of the present invention in detail, the following description is made in connection with the embodiments and the accompanying drawings.
Example 1
Referring to fig. 1, 4, 5, 6, 7, 8, 13, 14, 15, 16, 17, 18 and 19, a disposable air firecracker is composed of an upper membrane 1, a lower membrane 2, a middle membrane 3 and a side membrane 4, and an automatic air distribution device is additionally arranged. The upper film 1, the lower film 2, the middle film 3 and the side film 4 are referred to as PE films in this embodiment. The shape and thickness of the side film 4 and the middle film 3 are the same, the film 101 of the upper film 1 at the position of the aeration space 10 is thinner than those of other films, so that the upper film can be easily detonated, and the lower film 2 can be the same thickness as the whole film or completely the same as the upper film 1. In this embodiment, the structure of the upper film 1 and the lower film 2 is completely identical.
The middle membrane 3 and the side membrane 4 are positioned between the upper membrane 1 and the lower membrane 2, the middle membrane 3 is positioned at the central position, and the side membrane 4 is positioned at two sides of the middle membrane 3 between the upper membrane 1 and the lower membrane 2. The edges of the middle membrane and the upper membrane 1 are not fused by heat sealing except one part which is left as an air port A301, and all the rest parts are fused by heat sealing, so that an air placing space A5 is formed between the middle membrane 3 and the upper membrane 1 after heat sealing fusion; an air port B302 is also reserved between the middle membrane 3 and the lower membrane 2, a plurality of vent holes A303 are uniformly distributed in addition to the air port, and the edges of the rest middle membranes are fused with the lower membrane 2 in a heat sealing way, so that an air connecting space 6 is formed between the middle membrane 3 and the lower membrane 2 after the heat sealing fusion.
The edge of the edge membrane is not fused with the upper membrane 1 by heat sealing except one part which is left as an air port C401, and all the rest parts are fused by heat sealing, so that an air placing space B7 is formed between the edge membrane and the upper membrane after heat sealing; the side film and the lower film 2 are fused in a heat sealing way to form a plurality of explosion-passing spaces 8, a plurality of uniformly distributed vent holes B402 and a plurality of groups of explosion-passing holes are formed, and one explosion-passing space 8 is associated with one vent hole B402 and one group of explosion-passing holes.
The upper membrane 1 and the lower membrane 2 are respectively in heat sealing fusion with the middle membrane 3 and the side membrane 4, and the upper membrane 1 and the lower membrane 2 are also in heat sealing fusion, a plurality of gas containing spaces 9 and a plurality of gas explosion spaces 10 are partitioned by the heat sealing fusion area, the gas containing spaces 9 are respectively communicated with a plurality of uniformly distributed vent holes A303 and vent holes B402 in a corresponding way, and the gas explosion spaces 10 are respectively communicated with a plurality of groups of vent holes in a corresponding way.
The group of through-explosion holes consists of a plurality of through-explosion holes 403, the number of the holes of each group of through-explosion holes is different, the aperture of each through-explosion hole 403 can be different, the arrangement can be freely selected, the number of the holes can be different, the aperture can be different, and the number of the holes and the aperture can be different. This embodiment is referred to in terms of a combination of different numbers of holes and different phases of pore diameters. Such an arrangement may allow for different points in time for the membrane 101 to be detonated for each detonation space. The time difference of each explosion space explosion is generated to form continuous explosion time.
Referring to fig. 9, in a state where the gas-connection space 6 is filled with gas or gas, the middle membrane 3 is separated from the lower membrane 2 until being attached to the upper membrane 1, and the gas-connection space 6 is communicated with the gas-containing space 9 through the vent a301.
Referring to fig. 10, in the state where the gas accommodating space A5 is filled with gas, the middle membrane 3 is closely attached to the lower membrane 2, the vent a301 is closed by the middle membrane 3, and the plurality of gas accommodating spaces 9 are not communicated with each other.
Referring to fig. 11, in the state where the explosion venting space 8 is filled with air or gas, the edge membrane 4 is separated from the lower membrane 2 until being attached to the upper membrane 1, and one side of the explosion venting space 8 is communicated with the air containing space 9 through the vent hole B402, and the other side is communicated with the explosion venting space 10 through the explosion venting hole 403.
Referring to fig. 12, in the gas-filled state of the gas-containing space B7, the side film 4 is tightly attached to the lower film 2, the vent hole B402 and the vent hole 403 are closed by the side film 4, and the gas-containing space 9 cannot communicate with the gas-explosion space 10.
A disposable air firecracker forming step: referring to fig. 2, 9, 11, 14 and 16, the uninflated air firecrackers are spread out, and inflated towards the air port B302 of the middle membrane 3 and the lower membrane 2 by the automatic air distribution device, the air enters the air connection space 6 from the air port B302, then enters each air containing space 9 through each air hole a303 of the air connection space 6, enters the air hole B402 through the air containing space 9 and then enters the explosion venting space 8, then enters the explosion venting hole 403 through the explosion venting space 8 and finally enters the explosion venting space 10, when the explosion venting space 10 is just full but not burst, the state is that the middle membrane 3 is attached to the upper membrane 1, and the side membrane 4 is attached to the upper membrane 1. The whole air firecracker is formed initially, and the air pressure at the moment is based on the condition that the explosion space 10 can be fully blown but cannot be blown and exploded.
Referring to fig. 3, 12 and 17, when the whole air firecracker is formed initially, the air distribution device automatically changes the air distribution path, and the air distribution device is used for air distribution towards the air port C401 of the upper membrane 1 and the side membrane 4, so that the air distribution space B7 is fully filled, and the side membrane 4 is fully attached to the lower membrane 2. The air pressure at this time is based on the condition that the air accommodating space B7 is full, and the air accommodating space 9 and the air explosion space 10 cannot be communicated. Then the automatic air distribution device automatically changes the air charging path, and charges air towards the air port B302 of the middle membrane 3 and the lower membrane 2, wherein the air pressure is smaller than the air pressure of the air placing space B7, but is larger than the air pressure of the air explosion space 10, so that the air pressure capable of expanding the air explosion space 10 is achieved.
Referring to fig. 1, 10 and 15, after the above steps are completed, the air distribution device automatically changes the air distribution path, and the air is distributed towards the air ports a301 of the middle membrane 3 and the upper membrane 1, so that the air distribution space A5 is completely filled, and the middle membrane 3 is completely attached to the lower membrane 2. The air pressure is equal to the air placing space B at the moment, so that the air accommodating spaces 9 at the two sides of the air placing space A5 cannot be communicated, and the whole air firecrackers are completely inflated and are reserved for detonation.
The air pressure blown in from the automatic air distribution device is larger than the air pressure of the air placing space A5, the air pressure of the air placing space A can be equal to the air pressure of the air placing space B7 and is larger than the air pressure of the air containing space 9, and the air pressure of the air containing space 9 is larger than the air pressure of the air explosion space 10.
When the air firecracker is to be detonated, only the gas distribution pipe of the gas port C401 is required to be removed, (the description of the gas distribution pipe is described in detail in the embodiment 2), and then the gas in the gas placing space B7 flows out of the gas port C401. The air in the air-containing space B7 is less, the side film does not have so much pressure to block the vent hole B402 and the explosion vent 403, then the air in the air-containing space 9 enters the vent hole B402 and expands the explosion-venting space 8, enters the explosion vent 403, and finally enters the explosion-venting space 10, and as the film 101 of the explosion-venting space 10 cannot withstand more and more of the gas pressure, the explosion is generated as a result. The point in time at which each of the explosive spaces 10 is detonated is different, so that a series of sounds are generated.
One explosion space 10 can generate one sound by air in one air containing space 9 through one explosion space 8 and one group of explosion holes through the vent holes B402, and a plurality of sounds are generated in a plurality of explosion spaces 10. Because of the different setting of the groups of explosion vent holes associated with each explosion space 10, the explosion time points of the explosion spaces 10 are different, so a series of sounds are generated.

The working process of the air firecrackers and the automatic air distribution device is as follows:
the air is inflated towards the air channel 1401 of the air inflation rod, the air enters the through hole A1404 from the air channel 1401, then enters the loop 1402, enters the air channel 2401 of the plug in the mounting hole A1305 from the loop 1402, then enters the air tap A1302, enters the air connecting space 6 from the air tap A1302 through the air port B302, enters the air containing spaces 9 from the air connecting space 6 through the air holes A303, then enters the explosion space 8 through the air holes B402, finally enters the explosion space 10 through the explosion holes 403, when the air pressure of the explosion space 10 reaches and exceeds the elastic force of the spring A16, the air pressure pushes the plug 24 to move and compress the spring A16, when the plug 24 moves to the lower end sealing ring B21 to plug the mounting hole A1305, and the spring A16 cannot be compressed again, and when the plug 24 cannot be retracted, the air cannot enter the air tap A1302 (at this time, the air firecracker is just molded, the middle membrane 3 and the edge membrane 4 are attached to the upper membrane 1).
When the air pressure of the air channel 1401 of the air rod is larger than the elastic force of the spring B17 during the air inflation operation, the air pushes the steel ball 15, enters the steel ball mounting hole 1403 through the through hole B1405, enters the straight slot through the central through hole of the air bolt B19, and then enters the cylinder big hole 1301 and pushes the air rod 14 to move. When the loop 1402 moves to the installation hole B1306 where the other plug is located, gas enters the gas nozzle B1303 along the gas passage of the plug in the installation hole, and enters the two gas-placing spaces B7 from the gas nozzle B1303 through the gas-distributing pipe 25, and when the gas pressure in the gas-placing space B7 reaches and exceeds the spring force in the installation hole B1306, the plug and the sealing ring of the installation hole plug the installation hole B1306 again, and the process is the same as the movement of the plug 24 in the installation hole a 1305. (in this case, the edge film 4 is closely adhered to the lower film 2).
During the inflation operation, the gas in the air passage 1401 pushes the steel balls 15 and finally pushes the inflation rod 14 to move, when the ring 1402 moves to the mounting hole D1308, the gas enters the gas connection space 6 through the gas nozzle a and the gas port B302 through the gas nozzle a, and enters the gas containing spaces 9 through the gas connection spaces 6 and the gas holes a303, and when the gas pressure of the gas containing spaces 9 reaches and exceeds the spring force of the mounting hole D1308, the mounting hole D1308 is blocked by the plugs and the sealing rings of the mounting hole D1308, and the process is the same as the movement of the plugs 24 in the mounting hole a 1305.
During the inflation operation, the gas in the air passage 1401 pushes the steel balls 15 and finally pushes the inflation rod 14 to move, when the loop 1402 moves to the mounting hole C1307, the gas enters the air placing space A5 from the air tap C through the air port a301 through the air passage of the plug in the mounting hole C1307, and when the air pressure in the air placing space A5 reaches and exceeds the elastic force of the spring in the mounting hole C1307, the plug and the sealing ring of the mounting hole block the mounting hole C1307, and the process is the same as the movement of the plug 24 in the mounting hole a 1305. (in this case, the middle membrane 3 is closely adhered to the lower membrane 2)
During the inflation operation, the gas in the air passage 1401 will push the steel balls 15 and eventually push the inflation rod 14 to move, and when the ring 1402 moves to the space outside the barrel 13, the gas in the air passage 1401 is communicated with the natural gas and sounds the pressure gas to run out, and the inflation operation is completed.
Finally the inflator is closed and removed, pressing the inflation rod 14 into the barrel 13.
