Description

High pressure gas valve firing control device

This invention is related to a high-pressure gas valve firing control device, especially a firing control device that utilizes pressure balance and shaft displacement to form an impact action.

According to; the commonly used firing devices are usually designed to fire special objects to be fired, in response to different needs or uses. For example, a toy gun 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 filled gas rushes towards 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.

For example, a pneumatic rope throwing gun used for rescue releases the high-pressure air to generate an instantaneous expansion force, and then projects the rope to the target area. It uses a high-pressure air cylinder or a 30gm CO2 cylinder as the pressure source. For example, a pepper spray for self-defense usually uses a certain air pressure given in advance to make a pressure container tank. When in use, the opening at the top of the tank is pressed to generate a release and spray action. However, both rope throwing guns and pepper sprays have the disadvantage of complex structures, and they are all independent single products. Their firing devices cannot be shared with each other or applied to other products. Furthermore, as for pepper spray, since the air pressure in the pressure container is relatively low, the pepper spray is often blown back to the user due to the low pressure, causing the user to injure themselves.

In view of this, the applicant, after continuous research and experiments, came up with the idea of designing a high-pressure gas valve firing control device, which makes the structure and operation of the firing control device simpler and more convenient, and can be used with a variety of firing objects to meet different firing needs.

The main purpose of this invention is to provide a high-pressure gas valve firing control device, which uses pressure balance and shaft displacement to form an impact action to match a variety of firing objects, thereby achieving the purpose of responding to different firing needs.

The aforementioned high-pressure gas valve firing control device is provided with a firing seat filled with high-pressure gas, a through hole is provided at one end of the firing seat, a symmetrical supporting portion is provided on the inner wall, and a movable shaft is provided inside, a first piston for supporting on the through hole is sleeved on the front end of the shaft, and a first elastic element is passed through the shaft, a sleeve portion connected to the supporting portion is provided at the end of the shaft, and a second piston with a small diameter section in the center and a second elastic element are provided between the sleeve portion and the supporting portion. When the second piston is in the first position, the two ends of the second piston abut against the top support portion, and when the second piston moves from the first position to the second position due to external pressure, the two ends of the second piston leave the top support portion, causing the front and rear pressures of the firing seat to lose balance, thereby causing the piston to separate from the through hole, allowing the high-pressure gas to be discharged outward through the through hole. In this way, the invention can be combined with a container that contains objects to be fired, and the impact action of the high-pressure gas can be used to push the objects to be fired outward with high thrust.

In the aforementioned high-pressure gas valve firing control device, the front end of the firing seat is provided with a connecting section for coupling with the accommodating body, and the through hole is provided in the connecting section.

In the aforementioned high-pressure gas valve firing control device, the supporting portion of the inner wall of the firing seat is provided with blocks arranged opposite to each other at appropriate intervals, and a gas-stopping element is provided on the block, so that the two ends of the second piston abut against the gas-stopping element.

The aforementioned high-pressure gas valve firing control device, wherein the gas-stopping element is an oil seal, an O-ring or a gasket.

In the aforementioned high-pressure gas valve firing control device, the first elastic element is conical, and its front and rear ends are respectively positioned at the front edges of the first piston and the second groove.

The aforementioned high-pressure gas valve firing control device has a groove at the front end of the second piston for the second elastic element to be placed in the groove, so that the front and rear ends of the second elastic element are respectively supported on the sleeve portion at the end of the shaft and the groove of the second piston, thereby allowing the second piston to be displaced between the sleeve portion and the supporting portion.

Please refer to Figures 1 and 2 together with Figure 3, which are the three-dimensional diagram, three-dimensional exploded diagram and cross-sectional diagram of this invention. As shown in the figure, this invention is provided with a firing seat 1 for filling with high-pressure gas, a connecting section 11 is provided at the front end of the firing seat 1, a through hole 111 is provided in the connecting section 11, and a leak-proof gasket 112 is embedded between the firing seat 1 and the connecting section 11. The front edge of the firing seat 1 is provided with a first groove 12, and the inner wall of the rear edge is provided with a second groove 13, and a symmetrical top support 2 is provided in the second groove 13, wherein the top support 2 is a block 21, 22 arranged symmetrically with an appropriate spacing, and gas-stopping elements 211, 22 are provided in the blocks 21, 22 respectively. In this embodiment, the air-stopping elements 211 and 221 are oil seals, O-rings, or gaskets.

The first groove 12 of the firing seat 1 is provided with a movable and hollow shaft 3, the front end of the shaft 3 is sleeved with a first piston 31 that can be supported on or separated from the through hole 111, a leak-proof gasket 311 is provided between the first piston 31 and the shaft 3, and a first elastic element 32 is passed through the shaft 3, and the end of the shaft 3 is provided with a sleeve portion 33, so that the sleeve portion 33 is sleeved in the second groove 13, and the blocks 21 and 22 of the supporting portion 2 are embedded in the inner edge of the sleeve portion 33. In this embodiment, the first elastic element 32 is conical, and its front and rear ends are respectively positioned at the rear edge of the first piston 31 and the front edge of the second groove 13.

A second piston 4 is provided between the sleeve portion 33 and the supporting portion 2. A groove 41 is provided at the front end of the second piston 4 for a second elastic element 42 to be placed in the groove 41, so that the front and rear ends of the second elastic element 42 are supported on the sleeve portion 33 at the end of the shaft 3 and the groove 41 of the second piston 4, respectively, so that the second piston 4 can be displaced between the sleeve portion 33 and the supporting portion 2. The center of the second piston 4 is set as a small diameter section 43.

By combining the above components, a high-pressure gas valve firing control device is formed. When the second piston 4 is in the first position, the two ends of the second piston 4 are against the supporting portion 2, and when the second piston 4 moves from the first position to the second position due to external pressure, the two ends of the second piston 4 leave the supporting portion 2, so that the small diameter section 43 in the center of the second piston 4 is located between the air stop elements 211 and 221, and a certain gap is formed between the air stop elements 211 and 221, so that the pressure of the first groove 12 and the second groove 13 in front and behind the firing seat 1 loses balance, and then the first piston 31 is separated from the through hole 111, so that the high-pressure gas can be discharged outward through the through hole 111. In this way, the invention can be used to connect the joint section 11 with the container containing the object to be fired, and through the impact action of the high-pressure gas mentioned above, the object to be fired can be pushed outward with high thrust.

Please refer to Figure 4, which is a standby state diagram of this invention. As shown in the figure, when this invention is in the standby state, the shaft 3 is stretched by the elasticity of the first elastic element 32, so that the first piston 31 is supported on the through hole 111 of the firing seat 1, and the second piston 4 between the sleeve portion 33 and the supporting portion 2 is stretched by the elasticity of the second elastic element 42, so that the two ends of the second piston 4 are against the air stop elements 211 and 221 of the blocks 21 and 22, so that the high-pressure gas inside the firing seat 1 and the first groove 12 and the second groove 13 achieve pressure balance, thereby forming a standby state.

Please refer to Figure 5, which is a diagram of the action state of this invention. As shown in the figure, when this invention is used, a pressure button or other brake is used to apply pressure to the end of the second piston 4 from the outside, so that the second piston 4 moves from the first position to the second position, and the two ends of the second piston 4 are relatively separated from the air stop elements 211 and 221 of the top support part 2, so that the small diameter section 43 in the center of the second piston 4 is located between the air stop elements 211 and 221, and a certain gap is formed between the air stop elements 211 and 221, so that the high-pressure gas stored in the second groove 13 flows from the gap to the hollow part of the shaft 3, thereby causing the pressure of the first groove 12 and the second groove 13 to lose balance.

Please refer to Figure 6, which is a second action state diagram of the present invention. As shown in the figure, when the pressure of the first groove 12 and the second groove 13 lose balance, since the pressure of the first groove 12 is greater than that of the second groove 13, the shaft 3 will be pushed backward due to the pressure imbalance, so that the first piston 31 at the front end is separated from the through hole 111 of the through hole joint section 11, so that the high-pressure gas can be discharged outward through the through hole 111. In this way, the invention can be used to connect the joint section 11 with a container containing objects to be fired (such as pepper spray paste or BB bullets, paintballs, spheres, or other objects such as rescue nets), and the impact action of the high-pressure gas can push the objects to be fired outward with high thrust.

Please refer to Figure 7, which is a diagram of the return action state of the present invention. As shown in the figure, after the high-pressure gas is released outward through the through hole 111, the shaft 3 will re-support the first piston 31 on the through hole 111 due to the stretching elasticity of the first elastic element 32, and the second piston 4 will re-support the air-stopping elements 211 and 221 of the top holding part 2 blocks 21 and 22 due to the stretching elasticity of the second elastic element 42, so as to return to the standby state for filling high-pressure gas.

The above-mentioned embodiments are only for illustrating the preferred implementation of this creation, and are not intended to limit the scope of this creation. Any slight modification or change will not lose the essence of this creation, nor will it deviate from the spiritual scope of this creation.

In summary, this invention is a high-pressure gas valve firing control device composed of a firing seat, a shaft contained in the firing seat, and a piston that can be displaced by pressure. The impact action is formed by using pressure balance and the displacement of the shaft to match a variety of firing objects, thereby achieving a firing control device that corresponds to different firing needs. It is a practical design and a truly innovative creation. Therefore, a patent application 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.
