Description

High pressure gas valve firing device

This creation is about a high-pressure gas valve firing device, especially a high-pressure gas valve firing device that uses high-pressure gas to fire and can be used with a variety of firing objects to meet different firing requirements.

Press; The commonly used firing devices are usually designed to fire special objects to be fired, in response to different needs or uses. Take a toy gun as an example. It is mainly equipped with a small valve seat filled with gas, and a gun body and magazine that can be loaded with bullets such as BB bullets or paintballs. The gas is filled to the bullets to make them fired. However, the structure of the toy gun is quite complicated and difficult to assemble, so it is not suitable for a firing device that can be easily operated. Taking pepper spray for self-defense as an example, it is usually made into a pressure container tank with a certain pre-given air pressure. When in use, the release and spraying action is generated through the opening of the pressure head at the top of the tank. However, since the air pressure in the pressure container is relatively low, it is common for the pepper spray to be blown back to the user due to the low pressure after being sprayed, causing the user to injure themselves.

The aforementioned firing devices, whether toy guns or pepper sprays, all have complex structures or are difficult to operate or have deficiencies in use, and there is no unified standard or specification. If users want to meet the needs of all uses, they have to buy several toy guns or pepper sprays with different functions. It is unlikely that multiple different projectile objects can be used on the same type of firing device at the same time. For ordinary users, it is quite troublesome and troubling.

Please refer to Figures 1 and 2 together with Figures 3 and 4, which are the three-dimensional exploded view and three-dimensional view of the present invention, as well as the cross-sectional view and the cross-sectional view of the air valve body. As shown in the figure, the embodiment of the present invention comprises a to-be-fired object container 1 and an air valve body 2. Among them, the front end of the to-be-fired object container 1 is provided with a cover 11, and the cover 11 is provided with an opening 111. The inner edge of the front end is provided with a sleeve 12 combined with the cover 11, and the sleeve 12 is provided with an air hole 121 corresponding to the opening 111. A diaphragm 13 is provided between the cover 11 and the sleeve 12, so that the diaphragm 13 covers the air hole 121. A movable pusher 14 is provided inside the object container 1, and a leak-proof gasket 141 is provided around the periphery of the pusher 14. In this embodiment, the pusher 14 is configured to be conical, and the air hole 121 of the sleeve 12 is configured to correspond to the conical shape of the pusher 14.

The front end of the gas valve body 2 is provided with a stopper 21, a through hole 211 is provided in the stopper 21, and a leak-proof gasket 22 is provided around the periphery of the stopper 21. The end is provided with a step 23 with threads and a groove 24, so that a leak-proof gasket 25 can be embedded in the groove 24 and locked to the step 23 with a cap-shaped rear cover 26. The rear cover 26 is provided with a through hole 261, and a baffle 27 is provided inside the rear cover 26 so that the baffle 27 covers the through hole 261.

Inside the air valve body 2, there is a movable moving part 3. A generally inverted T-shaped limiting part 31 is penetrated at one end of the moving part 3, so that the limiting part 31 is placed on the step 23; a piston 32 is sleeved at the other end, and an elastic element 33 is sleeved on the moving part 3, one end of the elastic element 33 is limited to the piston 32, and the other end is limited to the limiting part 31. In this embodiment, the elastic element 33 is a conical spring, the smaller diameter end of which is limited to the piston 32, and the larger diameter end is limited to the limiting part 31.

By combining the above components, a high-pressure gas valve firing device is formed. To meet different firing requirements, the object to be fired 4 is placed in the object container 1, and high-pressure gas is poured into the gas valve body 2. The high-pressure gas causes the elastic element 33 to expand, so that the piston 32 is held against the through hole 211 of the stopper 21. When the baffle 27 is broken, the pressure loses balance and the moving part 3 moves backward, the piston 32 disengages from the through hole 211, and the high-pressure gas can be discharged to the object container 1 through the through hole 211, thereby pushing the pusher 14 in the object container 1 with a high thrust, and firing the object 4 outward.

The gas valve body 2 of the invention is an independent structure. This description is about combining it with the object container 1 to form an embodiment of a high-pressure gas valve firing device. However, the gas valve body 2 can also be combined with other different front end structures to form other types of high-pressure gas valve firing devices.

Please refer to Figures 5 and 6, which are the firing state diagrams of the invention. As shown in the figure, when the invention is in use, the pusher 14 is located behind the object container 1, supported by the stopper 21, so that the object container can hold the pepper spray paste (or bullet-shaped objects such as BB bullets, paint bullets, spheres, or other objects such as rescue nets) waiting for the firing object 4, and the gas valve body 2 is filled with high-pressure gas. When high-pressure gas is injected into the air valve body 2, the elastic element 33 is compressed and pushes the moving part 3 accordingly, so that the elastic element 33 is stretched, and the piston 32 abuts against the through hole 211 of the stopper 21, so that the high-pressure gas can be stored in the air valve body 2 in a sealed manner, and will not leak from the through hole 211 to the object container 1. Among them, since the air hole 121 of the sleeve part 12 is provided with a diaphragm 13, the object 4 can be stored in the object container 1 in a sealed manner.

When a striking body breaks the baffle 27 through the through hole 261, the pressure contained in the air valve body 2 loses balance due to the instantaneous gas release. Since the pressure in the front is greater than that in the rear, the moving member 3 moves backward to compress the elastic element 33 and push the piston 32, so that the piston 32 is separated from the through hole 211 of the stopper 21, and then the through hole 211 is opened. The high-pressure gas stored in the air valve body 2 can be discharged to the object container 1 through the through hole 211, and then the push member 14 in the object container 1 is pushed with high thrust, and then the object 4 is pushed, so that the object 4 breaks through the diaphragm 13 and fires outward.

The high-pressure gas valve firing device of the invention can be combined with different firing bodies, such as paint bullet guns, BB guns, riot control guns, rescue net throwing guns, etc. It only needs to match different firing bodies, put paint bullets, BB bullets, riot control objects, rescue net throwing objects 4 in the object storage body 1 to be fired, and then it can match the combined firing body to form the firing function of different objects 4 to be fired.

The above-mentioned embodiments are only for illustrating the better implementation of this creation, but not for limiting the scope of this creation. Any slight modification or change will not lose the essence of this creation and will not deviate from the spiritual scope of this creation.

In summary, this invention uses a connected gas valve body and a firing object container, and cooperates with high-pressure gas and the firing object contained in the gas valve body and the firing object container to form a high-pressure gas valve firing device. It uses high-pressure gas to fire, and can be matched with firing objects of different purposes to achieve the purpose of responding to different needs. It is a practical design and a truly innovative creation. Therefore, an application for a patent is filed in accordance with the law. I hope that the Jun Bureau will review it and grant the patent as soon as possible. I will be grateful.
