Detailed Description
In order to explain technical contents, structural features, and objects and effects achieved by the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Example 1
Referring to fig. 1, 4, 5, 6, 7, 8, 13, 14, 15, 16, 17, 18, 19, a disposable air cracker is composed of an upper membrane 1, a lower membrane 2, a middle membrane 3 and a side membrane 4, and is provided with an automatic air distribution device. 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 example. The side film 4 and the middle film 3 are the same in shape and thickness, the upper film 1 is thinner than the film 101 at the position of the explosion space 10 relative to the films at other positions, so that the explosion can be easier, and the lower film 2 can be the same in thickness as the whole film or can be the same as the upper film 1 completely. This embodiment is referred to as the structure of the upper film 1 and the lower film 2 which are identical.
The middle film 3 and the side film 4 are both arranged between the upper film 1 and the lower film 2, the middle film 3 is arranged at the central position, and the side films 4 are arranged at the two sides of the middle film 3 between the upper film 1 and the lower film 2. The edge of the middle film and the upper film 1 are all subjected to heat sealing fusion except for one part reserved as an air port A301, so that an air containing space A5 is formed between the middle film 3 and the upper film 1 after the heat sealing fusion; an air vent B302 is also reserved between the middle membrane 3 and the lower membrane 2, a plurality of vent holes A303 are uniformly distributed on the air vent B except the air vent, and the edges of the rest part of the middle membrane 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 and fusion.
The edge of the side film and the upper film 1 are all subjected to heat sealing fusion except for one part reserved as an air port C401, so that an air containing space B7 is formed between the side film and the upper film after the heat sealing fusion; the side film and the lower film 2 are fused in a heat sealing mode to form a plurality of through explosion spaces 8, a plurality of vent holes B402 and a plurality of groups of through explosion holes are evenly distributed, and one through explosion space 8 is associated with one vent hole B402 and one group of through explosion holes.
The upper membrane 1 and the lower membrane 2 are respectively in heat-seal fusion with the middle membrane 3 and the side membrane 4, the outer membrane 1 and the inner membrane 2 are also in heat-seal fusion, the heat-seal fusion area separates a plurality of air containing spaces 9 and a plurality of air explosion spaces 10, the air containing spaces 9 are respectively and correspondingly communicated with a plurality of uniformly distributed vent holes A303 and vent holes B402, and the air explosion spaces 10 are respectively and correspondingly communicated with a plurality of groups of vent holes.
The set of through explosion holes is composed of a plurality of through explosion holes 403, the number of the through explosion holes in each set is different, the aperture of each through explosion hole 403 can also be different, the setting can be freely selected, the number of the through explosion holes can be different, the aperture can be different, or the number of the through explosion holes can be different from that of the through explosion holes, and the different apertures can be combined together. This embodiment is referred to in terms of a combination of differences in the number of holes and differences in the diameter of the holes. Such an arrangement may cause the time points at which the membranes 101 burst in the respective burst spaces to be different. Therefore, the time difference of explosion of each explosion space is generated to form continuous explosion time.
Referring to fig. 9, when the air-communicating space 6 is filled with air or gas, the middle membrane 3 is separated from the lower membrane 2 until it is attached to the upper membrane 1, and the air-communicating space 6 is communicated with the air-containing space 9 through the vent hole a 301.
Referring to fig. 10, when the gas containing space a5 is in a full gas state, the middle membrane 3 and the lower membrane 2 are tightly attached, the vent hole a301 is sealed by the middle membrane 3, and the plurality of gas containing spaces 9 are not communicated with each other.
Referring to fig. 11, when the explosion-proof space 8 is filled with gas or gas, the side film 4 is separated from the lower film 2 until it is attached to the upper film 1, and one side of the explosion-proof space 8 is communicated with the gas-containing space 9 through the vent hole B402, and the other side is communicated with the explosion-proof space 10 through the explosion-proof hole 403.
Referring to fig. 12, when the gas accommodating space B7 is in a full gas state, the side film 4 and the lower film 2 are tightly attached, the vent hole B402 and the explosion hole 403 are sealed by the side film 4, and the gas accommodating space 9 cannot be communicated with the explosion space 10.
A one-off air firecracker forming step:
referring to fig. 2, 9, 11, 14 and 16, the uninflated air firecracker is 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 communicating space 6 from the air port B302, then enters each air containing space 9 through each vent hole a303 of the air communicating space 6, enters the vent hole B402 through the air containing space 9, then enters the explosion communicating space 8, then enters the explosion communicating hole 403 through the explosion communicating space 8, and finally enters the explosion space 10, when the explosion space 10 is just full but not burst, 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 preliminarily formed, and the air pressure at the moment is based on the condition that the air explosion space 10 can be fully blown but cannot be blown to explode.
Referring to fig. 3, 12 and 17, when the whole air firecracker is initially formed, the air distribution device automatically changes the air inflation path to inflate towards the air ports C401 of the side film 4 and the upper film 1, so that the air containing space B7 is completely full, and the side film 4 and the lower film 2 are completely attached. The air pressure at this time is based on the air containing space B7 being blown to be full, and the air containing space 9 and the air explosion space 10 cannot be communicated. Then the automatic air distribution device automatically changes the air charging path to charge air towards the air ports B302 of the middle membrane 3 and the lower membrane 2, but the air charging pressure is smaller than the air charging space B7 but larger than the air explosion space 10, so as to reach the air pressure capable of expanding the air explosion space 10.
Referring to fig. 1, 10 and 15, after the above steps are completed, the air distribution device automatically changes the air inflation path to inflate the air towards the air ports a301 of the middle membrane 3 and the upper membrane 1, so that the air space a5 is completely full, and the middle membrane 3 and the lower membrane 2 are completely attached. The air pressure is equal to the air placing space B, so that the air accommodating spaces 9 on the two sides of the air placing space A5 cannot be communicated, and the whole air firecracker is left to be detonated after the air is filled.
The air pressure blown 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 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 air distributing pipe of the air port C401 is removed (the air distributing pipe is described in detail in embodiment 2), and then the air in the air space B7 flows out of the air port C401. The air in the air accommodating space B7 is less, the side membrane has not so much pressure to block the vent hole B402 and the explosion vent 403, then the air in the air accommodating space 9 enters the vent hole B402 and props up the explosion vent 8, enters the explosion vent 403 and finally enters the explosion space 10, and the explosion sound is produced as the membrane 101 in the explosion space 10 cannot bear more and more gas pressure. The time at which each explosion space 10 is burst is different, and thus a series of sounds are generated.
One air accommodating space 9 allows one explosion space 10 to generate one sound through one explosion space 8 and a plurality of explosion holes through the vent holes B402, and a plurality of explosion spaces 10 generate a plurality of sounds. Because the different sets of the through holes associated with the respective explosion spaces 10 cause different explosion time points of the explosion spaces 10, a series of sounds are generated.
Example 2

The two sides of the loop 1402 of the inflation rod 14 are respectively provided with a sealing ring C22, and one end of the inflation rod is used for connecting an external inflation mechanism, wherein the inflation mechanism can be a household inflator, an inflation pump or other inflation tools.
The working process of matching the air firecrackers and the automatic air distribution device is as follows:
the air is inflated towards an air duct 1401 of the inflation rod, the air enters a through hole A1404 from the air duct 1401, then enters an annular duct 1402, enters an air duct 2401 of a plug in an installation hole A1305 from the annular duct 1402, then enters an air nozzle A1302, enters an air connecting space 6 from the air nozzle A1302 through an air hole B302, enters each air accommodating space 9 from the air connecting space 6 through each air vent A303, then enters an explosion through air vent B402 into an explosion through space 8, finally enters an explosion through hole 403 into an explosion space 10, when the air pressure of the explosion space 10 reaches and exceeds the elastic force of a spring A16, the air pressure pushes the plug 24 to move and compress a spring A16, when the plug 24 moves to a lower end sealing ring B21 to block the installation hole A1305, the spring A16 cannot be compressed again, and when the plug 24 is unreleasable to retreat, the air cannot enter the air nozzle A plug (at this time, the air plug 1302 is just formed, and the middle membrane 3 and the side membrane 4 are attached to the upper membrane 1).
When the air pressure of the air duct 1401 of the air inflation rod is larger than the elastic force of the spring B17, the air pushes the steel ball 15, enters the steel ball mounting hole 1403 through the through hole B1405, enters the straight groove through the central through hole of the air vent bolt B19, and then enters the cylinder big hole 1301 and pushes the air inflation rod 14 to move. When the circular path 1402 moves to the installation hole B1306 at the other end plug, the air enters the air nozzle B1303 along the air path of the end plug in the installation hole, and then enters the two air spaces B7 through the air distribution pipe 15 from the air nozzle B1303, and when the air pressure in the air space B7 reaches and exceeds the elastic force of the spring in the installation hole B1306, the end plug and the sealing ring of the installation hole block the installation hole B1306, which is the same as the movement of the end plug 24 in the installation hole a 1305. (in this case, the side film 4 is in close contact with the lower film 2).
During the inflation operation, the gas in the air duct 1401 pushes the steel ball 15 and finally the inflation rod 14 to move, when the loop 1402 moves to the installation hole D1308, the gas enters the air connecting space 6 from the air tap a through the air port B302 via the air passage of the plug in the installation hole D1308, and enters the air accommodating spaces 9 from the air connecting space 6 through the air vents a303, when the air pressure in the air accommodating spaces 9 reaches and exceeds the spring force of the installation hole D1308, the plug and the sealing ring of the installation hole plug up the installation hole D1308, and the process is the same as the movement of the plug 24 in the installation hole a 1305.
During the inflation operation, the gas in the air duct 1401 pushes the steel ball 15 and finally pushes the inflation rod 14 to move, when the loop 1402 moves to the installation hole C1307, the gas passes through the air duct of the plug in the installation hole C1307 and enters the air accommodating space a5 through the air port a301 by the air nozzle C, and when the gas pressure in the air accommodating space a5 reaches and exceeds the elastic force of the spring in the installation hole C1307, the plug and the sealing ring of the installation hole block the installation hole C1307 again, which is the same as the movement of the plug 24 in the installation hole a 1305. (in this case, the middle film 3 is closely attached to the lower film 2)
When the air in the air duct 1401 pushes the steel ball 15 and finally the air-inflating rod 14 to move during the air-inflating operation, when the loop 1402 moves to the space outside the cylinder 13, the air in the air duct 1401 is communicated with the natural air and makes a sound of the pressure air to escape, and the air-inflating operation is finished.
Finally the inflator is closed and removed, and the inflation rod 14 is pressed into the barrel 13.
According to the corresponding association condition of the spring in the air distribution device and each space in the air firecracker, the following results are obtained: spring in mounting hole C1307 = spring in mounting hole B1306 > spring in mounting hole D1308 > spring in mounting hole a 1305.
