Description
- The present disclosure relates to a portable carbon dioxide adapter system, and more particularly to a portable carbon dioxide adapter system for pressurizing and injecting gas to a gas-injection object such as an airgun or an airsoft apparatus by a disposable carbon dioxide high pressure gas cylinder.
- Using power from a compressed gas is one of most common approaches to shoot a projectile for an airsoft that shoots a BB bullet (i.e., a 6mm or 8mm spherical plastic projectile) or an airgun (such as an air rifle) that shoots a metal projectile. Common compressed gases include propane, green gas (mixture of propane and a very small amount of silicone oil), HFC-134a, carbon dioxide, and the like. Compared with other gases, liquid carbon dioxide stores amazing energy and has an ideal greenhouse effect index (the ability of a gas to absorb thermal energy under the same temperature and the same pressure). This is why carbon dioxide high pressure gas cylinders are widely applied to airguns (e.g., air rifles). Some airsoft guns (for example, air pistols), which are specially designed to withstand high pressure gas, may also use carbon dioxide to shoot a BB bullet.
- In the airgun and airsoft industries, gas pressure potential energy is usually stored in a 12g compressed carbon dioxide gas cylinder for direct use, or gas is injected into a gas storage cavity inside a gun body or a fixed gas tank connected to the gun body by a hand pump, an air compressor or a scuba tank. Although large volume (e.g., 88g) disposable compressed carbon dioxide gas cylinders are commercially available, they can only be directly used by very few airguns. Therefore, a carbon dioxide adapter designed for the large volume (e.g., 88g) disposable compressed carbon dioxide gas cylinders is desired, which may safely inject gas to and pressurize the gas storage cavity or fixed gas tank while avoiding leakage of carbon dioxide. In this way, it is convenient for users to use the large volume disposable compressed carbon dioxide gas cylinders for various gas-injection objects including those in the airgun industry.

Fig. 1 is an assembly structure diagram of a portable carbondioxide adapter system 100 according to a preferred embodiment of the present disclosure. As shown inFig. 1 , the portable carbondioxide adapter system 100 in an assembled state comprises: aconnection port 101 for connecting to a liquid carbon dioxide source; aninjection nozzle 102 for injecting gaseous carbon dioxide to a gas-injection object; a gasifyingsection 103 that converts liquid carbon dioxide into gaseous carbon dioxide; and anadjuster 104 for adjusting carbon dioxide flow, wherein theconnection port 101 is preferably connected to a large volume disposable compressed carbon dioxide gas cylinder (not shown) in a threaded manner. The disposable compressed carbon dioxide gas cylinder (e.g., CO2-88G) stores inside liquid carbon dioxide and is provided with an external thread at a gas cylinder outlet; a corresponding internal thread is provided inside theconnection port 101, thereby achieving a reliable engagement between the two threads. In the airgun or airsoft industry, valve rods of gas inflow valves of various gas-injection objects (including gas-injectable 12g gas cylinders) are substantially of the same type and size. Therefore, theinjection nozzle 102 may inject gas to almost all airguns or airsoft products. Hereinafter, all products, which use high pressure carbon oxide and may be injected with gas using theinjection nozzle 102, are collectively referred to as gas-injection-by-adapter objects. - To facilitate user operation, as shown in
Fig. 1 , optionally an external thread is provided on an outer periphery of an adapter collar which receives theinjection nozzle 102, for further attaching hoses and other input nozzles according to user needs, thereby implementing direct gas-injection to the gas-injection-by-adapter object. Inside the gasifyingsection 103 is a volume-adjustable cavity structure. Theadjuster 104 adjusts the volume of an internal cavity of the gasifyingsection 103 through a conventional screw configuration and a pressure adjusting spring, thereby controlling carbon dioxide flow. The specific structures of the gasifyingsection 103 and theadjuster 104 will be further described with reference to the accompanying drawings. -
Fig. 2A is a plane sectional view of the portable carbondioxide adapter system 100 ofFig. 1 .Fig. 2B is an exploded structure diagram of the portable carbondioxide adapter system 100 ofFig. 1 . Hereinafter, respective components of the portable carbondioxide adapter system 100 ofFig. 1 and working manners thereof will be elaborated with reference to the plane section view ofFig. 2A and the structural exploded diagram ofFig. 2B . - As shown in
Fig. 2A , various components making up the portable carbondioxide adapter system 100 may be partitioned into the following assemblies by functions: anadapter collar assembly 11, an injectionnozzle valve assembly 12, a gasifying/flow adjusting assembly 13, a sealing ring andguard ring assembly 14, a compositedrill bit assembly 15, and a gascylinder collar assembly 16. When injecting gas to a gas-injection-by-adapter object, the carbon dioxide enters from the compositedrill bit assembly 15 into the portable carbondioxide adapter system 100 along an assembly axial direction from right to left, and is finally injected into the gas-injection-by-adapter object from the injectionnozzle valve assembly 12. -
Fig. 2B further shows structural details of respective components that make up the portable carbondioxide adapter system 100 along a horizontal assembly axis from left to right. As shown inFig. 2B , theadapter collar assembly 11 comprises acollar body 111 and alocking pin 112. A left end of thecollar body 111 is provided with a stepped through-hole within which the injectionnozzle valve assembly 12 is received in a slidable manner; a right end of thecollar body 111 is connected to the gasifying/flow adjusting assembly 13 in a threaded manner. Specifically, a right end of thecollar body 111 is provided with an internal thread, while a left end of the gasifying/flow adjusting assembly 13 is correspondingly provided with an external thread, such that thecollar body 111 and the gasifying/flow adjusting assembly 13 are engaged in a threaded manner, and an airtight structure is implemented in a connected state via an O-shaped sealing ring (not shown). Thelocking pin 112 is for the purpose of preventing thread loosening, such that theadapter collar assembly 11 is securely locked to the gasifying/flow adjusting assembly 13 during the gas-injection process. - The injection
nozzle valve assembly 12 comprises anozzle valve rod 121, an embeddedsealing ring 122, anend sealing collar 123, anend locking cap 124, and atension spring 125. Thenozzle valve rod 121 is a stepped cylinder with outer diameters of two ends being smaller than an outer diameter of a central part; a left end of the nozzle rod is a hollow nozzle hole for injecting carbon dioxide gas, and a right end of the gas cylinder is a solid screw for engaging theend locking cap 124; on the larger-diameter central part of the cylinder is provided with an annular groove for receiving the embeddedsealing ring 122; the embeddedsealing ring 122 is for slidably sealing between thenozzle valve rod 121 and theadapter collar assembly 11 so as to avoid leakage of the carbon dioxide gas to an outer atmosphere during the gas-injection process. In addition, between the annular groove of thenozzle valve rod 121 and a right end face of the larger-diameter cylinder is further provided a gas inflow hole that is completely or partially through in the diameter direction and communicates with the nozzle hole. Theend sealing collar 123 abuts against a right end face of the larger-diameter cylinder of thenozzle valve rod 121 and is secured through theend locking cap 124; the outer diameter of theend sealing collar 123 is larger than a left end through hole of theadapter collar assembly 11, such that theend sealing collar 123, when being tensioned by thetension spring 125, ensures sealing between the injectionnozzle valve assembly 12 and the gasifying/flow adjusting assembly 13 in a non-gas-injection state. A left end of thetension spring 125 is snapped to a right end bulge of theend locking cap 124, while a right end of thetension spring 125 abuts against a left end face of the gasifying/flow adjusting assembly 13. When injecting gas to the gas-injection-by-adapter object, as thetension spring 125 is compressed, the sealing between the injectionnozzle valve assembly 12 and the gasifying/flow adjusting assembly 13 is released, and the gas inflow hole of thenozzle valve rod 121 is exposed, such that high-pressure carbon dioxide gas enters into the gas inflow hole and reaches the hollow nozzle hole at the left end of thenozzle valve rod 121. Those skilled in the art will easily appreciate that by appropriately disposing the annular groove of thenozzle valve rod 121 and setting a maximum compressed amount of thetension spring 125, it is guaranteed that during the gas-injection process, the carbon dioxide only enters into the gas inflow hole, without compromising the slidable sealing of the embeddedsealing ring 122. - The gasifying/
flow adjusting assembly 13 comprises agasification cavity body 131, aflow adjusting worm 132, apressure adjusting spring 133, and alocking bolt 134. Thegasification cavity body 131 is a hollow inner cavity configuration of a locally threaded hole that is top-down through; meanwhile, a gaseous carbon dioxide outflow hole is provided on a left end face of thegasification cavity body 131, and a liquid carbon dioxide inflow hole is provided on a right end face of thegasification cavity body 131; preferably, the liquid carbon dioxide inflow hole is greater than the gaseous carbon dioxide outflow hole, so as to prevent blockage or unsmooth flowing of the liquid carbon dioxide due to surface tension. Left and right ends of thegasification cavity body 131 are of an external thread structure, for being correspondingly engaged with inner threads of theadapter collar assembly 11 and the gascylinder collar assembly 16, respectively. Preferably, a left end face of the gasifyingcavity body 131 is of an inwardly recessed structure so as to securely receive thetension spring 125 of the injectionnozzle valve assembly 12. Theflow adjusting screw 132, thepressure adjusting spring 133, and alocking bolt 134 are connected or mounted in the top-down through locally threaded hole of the gasifyingcavity body 131 so as to adjust the volume of the hollow inner cavity of the gasifyingcavity body 131. Preferably, a sealing gasket is provided at an end of theflow adjusting screw 132, and a sealing piston (not shown) is mounted on thepressure adjusting spring 133; both of the sealing gasket and the sealing piston are for sealing the gasifyingcavity body 131, avoiding leakage of the gasified carbon dioxide to the outside. The specific structures of respective components of the gasifying/flow adjusting assembly 13 as well as assembly manners thereof will be further illustrated with reference to the drawings. - The sealing ring and
guard ring assembly 14 comprises an O-shapedsealing ring 141 and asilicone guard ring 142. The O-shapedsealing ring 141 is for sealing between the gasification/flow adjusting assembly 13 and the gascylinder collar assembly 16, which prevents the silicongel guard ring 142 from blocking the liquid carbon dioxide inflow hole on the right end face of the gasifyingcavity body 131. The silicongel guard ring 142 can buffer an impact from the compositedrill bit assembly 15, and a central opening of the silicongel guard ring 142 allows the liquid carbon diode to smoothly enter the gasifying/flow adjusting assembly 13 from the disposable carbondioxide gas cylinder 13.
The compositedrill bit assembly 15 comprises a drill bit-type opener 151 and a hollowdrill bit holder 152. The hollowdrill bit holder 152 is used to fixedly support the drill bit-type opener 151; a spiral groove shape of the drill-bit type opener 151 can ensure that the liquid carbon dioxide flows smoothly to the gasification cavity when the disposable carbon dioxide gas cylinder is opened. The hollow drill-bit holder 152 is a hollow cylinder, a left end face of which abuts against the sealing ring and the silicagel guard ring 142 of thecollar assembly 14, and a right end face of which abuts against an inner annular flange of the gascylinder collar assembly 16. In a state of use, the drill-bit type opener 151 held by the hollowdrill bit holder 152 extends out of the hollowdrill bit holder 152 and beyond the inner annular flange of the gascylinder collar assembly 16 so as to open the disposable carbon dioxide gas cylinder. Additionally and alternatively, the hollowdrill bit holder 152 and the drill-bit type opener 151 may also adopt an integrated structure instead of the split structure shown in the figure. - The gas
cylinder collar assembly 16 comprises a gascylinder collar body 161 and alocking pin 162. A left end of the gascylinder collar body 161 is connected to a right end of the gasification/flow adjusting assembly 13 in a threaded manner. Likewise, the lockingpin 162 is used for preventing thread loosening, such that the gascylinder collar assembly 16 is securely locked to the gasification/flow adjusting assembly 13 during the gas-injection process. As mentioned above, the right end of the gascylinder collar body 161 is used for being connected to a carbon dioxide source, that is, connected to a large volume disposable compressed carbon dioxide gas cylinder (e.g., CO2 -88 G) in a threaded manner. -
Fig. 3 is a diagram showing structural details of a gasification/flow adjusting section in the portable carbon dioxide adapter system according to a preferred embodiment of the present disclosure. When gas is injected to a gas-injection-by-adapter object by the large volume disposable carbon dioxide gas cylinder, it is important to ensure safe release of gas pressure potential energy and adjustability of the gas flow. The gasification/ flow adjustment section according to a preferred embodiment of the present disclosure may achieve this point through a simple structure. As indicated by the arrow ofFig. 3 , the liquid carbon dioxide flows in from a small hole in the left end face of thegasification cavity body 131 and is ejected out of a small hole in the right end face of thegasification cavity body 131 in a gaseous form after gasification and expansion in an inner cavity of thegasification cavity body 131; thegasification cavity body 131 made of a special metal can withstand high-pressure carbon dioxide in strength so as to ensure safe release of the gas pressure potential energy. In order to adjust flow of the gasified carbon dioxide, a through hole (with internal threads being provided at both ends) is opened in thegasification cavity body 131 along a direction perpendicular to a flowing direction of the carbon dioxide indicated by the arrow, and a dimension of gasification space inside thegasification cavity body 131 is adjusted by screwing theflow adjusting screw 132 within the through hole, thereby achieving the purpose of adjusting the flow of carbon dioxide. In order to ensure the sealing effect while adjusting the flow, a sealing gasket is arranged at an end of theflow adjusting screw 132, and meanwhile the sealing piston is assembled above thepressure adjusting spring 133 in the through hole, so that the sealing piston abuts against theflow adjusting screw 132; the sealing piston comprises apiston rod 135 with a sealing collar and apiston cap 136 for securing the sealing collar. Thelocking bolt 134 is used for locking thepressure adjusting spring 133 in the through hole. As described above, the sealing piston and the sealing gasket are used for sealing thegasification cavity body 131 so as to prevent leakage of the gasified carbon dioxide to the outside. -
Figs. 4A-4C are schematic diagrams showing use states of the portable carbon dioxide adapter system according to a preferred embodiment of the present disclosure. As shown inFigs. 4A-4C , in the use states, an operator connects one end of the portable carbondioxide adapter system 100 to a disposable carbondioxide gas cylinder 200 in a threaded manner; meanwhile, the operator presses tightly the other end till the valve rod of the gas inflow valve of the gas-injection object 300 to pressurize and inject gas; besides, the flow of gas injection may be adjusted through the gasification/ flow adjusting section. Therefore, it is very convenient to use. Those skilled in the art will readily appreciate that the gas-injection object 300 can be a gas storage cavity within the gun body or a fixed gas storage tank which is connected with the gun body, and can also be various products including gas-injectable 12g gas cylinders. Therefore, the portable carbondioxide adapter system 100 according to the present disclosure has a wide industrial application and is not limited to the airsoft or airgun industry. - The above disclosed are only preferred embodiments of the present disclosure, and the scope of the invention are not defined thereby, of course. Therefore, any equivalent changes within the patent application scope of the present disclosure fall within the scope of the invention. It is to be understood that the above description is intended to be illustrative and not restrictive.
