【detailed description】

The utility model mainly discloses the structural composition of a time-delayed explosive cartridge. The basic principles of gunpowder used in it, including physical principles and chemical principles, are well known to those skilled in the relevant technical fields, so the following descriptions will not be fully described. . At the same time, the diagrams compared below mainly express the structural representations related to the features of the present utility model, and are not and need not be completely drawn according to the actual size, and are explained first.

Please refer to FIG. 1 , which is a schematic cross-sectional view of a time-delayed explosive cartridge 1 based on the concept of the present utility model. Delayed detonation cartridge 1 includes a hollow cylinder body 100, a powder pack 200, a seat body 400, a gas generating device 300, an electric energy storage device 620, a circuit device 610, a timing device 630 and an electronic ignition device 640 .

The circuit device 610 is driven by the electric energy storage device 620 to operate, and the circuit device 610 controls the correct operation of the timing device 630 and the electronic ignition device 640 .

The hollow body 100 has an opening 110 , and is coupled to the periphery of the base 400 through the opening 110 , so that an accommodating space 120 is formed between the hollow body 100 and the base 400 . The powder pack 200 and the gas generating device 300 are disposed in the accommodating space 120 , the gas generating device 300 is connected to the powder pack 200 , and the powder pack 200 is connected to the electronic ignition device 640 . The electric energy storage device 620 , the circuit device 610 , the timing device 630 and the electronic ignition device 640 are all disposed on the base body 400 . Since the time-delayed explosive cartridge 1 is disposable and does not need to be recovered after blasting, the electric energy storage device 620 is preferably a dry battery, or a small micro battery or a button battery. Of course, if the long-term storage of the delayed-explosion cartridge 1 or the effective control of the electric power are considered, the electric energy storage device 620 can also use a storage battery, a lithium battery, and the like.

Please refer to FIG. 1 and FIG. 2 , the time-delayed explosive cartridge 1 further includes a manually operable safety switch 650 connected to the circuit device 610 and disposed at the bottom of the base body 400 . When the safety switch 650 is set to the "OFF" state, the electric energy storage device 620 will be switched to the state of being isolated and disconnected from the circuit device 610. At this time, the electronic ignition device 640 and the timing device 630 will not operate due to lack of electric energy. When the safety switch 650 is set in the "on" state, the electric energy storage device 620 will be switched to be connected to the circuit device 610 , and the electronic ignition device 640 and the timing device 630 will operate under the control of the circuit device 610 .

Please refer to FIG. 1 and FIG. 2 , the delayed-explosion cartridge 1 further includes a trigger button 660 connected to the circuit device 610 and disposed outside the bottom of the base body 400 . The trigger button 660 is used for firing the delayed-explosion cartridge 1. When the delayed-explosion cartridge 1 is fired by the launcher, whether it is fired with a gas or a mechanical striker, the launcher will trigger the delayed-explosion cartridge. 1, the trigger button 660 will be touched. When the safety switch 650 is set in the “on” state, the trigger button 660 will send a signal to the circuit device 610 , and the circuit device 610 will start the timing device 630 accordingly. The timing device 630 is preset with a delay time, such as 3 seconds, 5 seconds, or longer time. After the timing device 630 is activated, it starts to count down the delay time. The energy provided by the device 620 is ignited to ignite the charge 200 . The powder pack 200 is ignited to generate a large amount of heat energy, and the gas generating device 300 undergoes a chemical change after receiving the heat energy to generate a large amount of gas, which rapidly expands in volume and increases in pressure, and finally breaks through the hollow cylinder body 100, resulting in an explosion.

The accommodating space 120 of the time-delayed explosion cartridge 1 can be further provided with fire extinguishing agent or paprika and tear gas for riot suppression. .

It must be emphasized that the launcher for firing the delayed explosive cartridge 1 can be refitted from a common tear gas egg launcher or a shell launcher, which is not the object emphasized by the present invention.

The delay time of the timing device 630 can be set flexibly, mainly considering the use scene, the flight speed and flight time of the delayed explosive cartridge 1 in the air. If the percussion energy of launcher is big, and the time of delayed explosion cartridge 1 flight is longer, just can preset longer delay time; If the time of delayed explosion cartridge 1 flight is shorter, just can pre-set shorter short delay time. Preferably, the delay time setting is slightly shorter than the flight time, so that the delayed explosion cartridge 1 can be exploded in the air in the target area, and the fire extinguishing agent, chili powder, tear gas, etc. in the hollow body 100 can be discharged from the air to the ground. spread. Since under normal circumstances, the specific gravity of fire extinguishing agent, chili powder, and tear gas is slightly heavier than that of air, spreading from the air to the ground can have a better effect.

For ease of assembly, preferably, please refer to FIG. 1 , the seat body 400 includes a first seat body 410 and a second seat body 420 engaged with each other, and the opening 110 of the hollow cylinder body 100 is combined with the periphery of the first seat body 400 so that An accommodation space 120 is formed between the two. The electric energy storage device 620 is disposed between the first base 410 and the second base 420 . The electronic ignition device 640 is disposed on the first seat body 410 and is close to the powder pack 200 . The safety switch 650 is disposed on the bottom of the second base body 420 to facilitate manual operation.

Further, please refer to Fig. 1, the opening 110 of the hollow body 100 of the delayed-explosion cartridge 1 is provided with a first thread 111, and the periphery of the first seat 410 is provided with a second thread 411 for coupling to the first thread 111. The first seat 410 is provided with a third thread 412 facing the second seat 420 ; the second seat 420 is provided with a fourth thread 421 facing the first seat 410 for combining with the third thread 412 .

Preferably, please refer to Fig. 1, the hollow body 100 is further formed with a plurality of weakened structures 130 that are easy to break, and the weakened structures 130 mainly include stress concentration structures. When the gas generating device 300 generates a large amount of gas and high pressure, due to the stress Focusing on the weakened structure 130 makes it particularly vulnerable to rupture and explosion.

Preferably, in order to reduce the harm to human body or animals, the hollow body 100 of the delayed-explosion cartridge 1 is made of polymer materials, and metal materials are not used as far as possible. More soft materials can be used, and when the delayed-explosion cartridge 1 is fired abnormally and hits an object in advance, including a human body or a building, the damage to the object can be reduced.
