Description

Portable carbon dioxide adapter system

Technical Field

The present invention relates to a portable carbon dioxide adapter system, and more particularly, to a portable carbon dioxide adapter system for pressurizing and inflating an object to be inflated, such as an air gun or a soft air gun, using a disposable carbon dioxide high-pressure gas cylinder.

Background

Whether soft air guns that fire BB projectiles (i.e., 6mm or 8mm spherical plastic projectiles) or air guns that fire metal projectiles (e.g., air rifles), one of their most common methods for firing projectiles is to use energy from compressed gases, such as propane, green gas (a mixture of propane and a very small amount of silicone oil), HFC-134a, carbon dioxide, and the like. Since liquid carbon dioxide stores tremendous energy and has an ideal greenhouse effect index (referring to the ability of a gas at the same temperature and pressure to absorb heat energy) compared to other gases, high pressure carbon dioxide cylinders are widely used in air guns (e.g., air rifles), and some soft air guns (e.g., air pistols) that are specifically designed to withstand high pressure gases may also use carbon dioxide to fire BB projectiles.

In the air gun and soft air gun industry, the air pressure potential energy is stored in a compressed carbon dioxide cylinder of 12 g for direct use, or an air storage cavity in the gun body or a fixed air storage tank connected with the gun body is inflated by means of a hand pump (hand pump), an air compressor (air compressor) or a gas tank (scuba tank). Although disposable compressed carbon dioxide cylinders of larger capacity, e.g. 88 grams, are also offered on the market, such large capacity cylinders can be used directly as long as there are very few air guns. Accordingly, it would be desirable to have a carbon dioxide adapter designed for a large capacity, e.g., 88 gram, disposable compressed carbon dioxide cylinder that safely inflates the reservoir or fixed reservoir and prevents carbon dioxide leakage, thereby facilitating the use of the large capacity disposable compressed carbon dioxide cylinder by the user on a variety of inflatable objects, including the air gun industry.

FIG. 1 is an assembled block diagram of a portable carbon dioxide adapter system 100 according to a preferred embodiment of the present invention. As shown in fig. 1, in an assembled state, portable carbon dioxide adapter system 100 comprises: a connection port 101 for connection to a source of liquid carbon dioxide gas; an injection nozzle 102 for injecting gaseous carbon dioxide to the inflation subject; a gasification part 103 for converting liquid carbon dioxide into gaseous carbon dioxide, and a regulator 104 for regulating the flow rate of carbon dioxide, wherein the connection port 101 is preferably connected to a large-capacity disposable compressed carbon dioxide cylinder (not shown) in a threaded manner, the disposable compressed carbon dioxide cylinder (for example, CO2-88G) stores liquid carbon dioxide therein and is externally threaded at the cylinder outlet part, and correspondingly, internal threads are provided in the connection port 101 to achieve reliable connection of the two. In the air gun or soft air gun industry, the valve stems of the inlet valves of various inflation subjects (including inflatable 12 gram gas cylinders) are all substantially the same type or size, and thus the injection nozzle 102 can inflate almost all air gun or soft air gun products, hereinafter collectively referred to as adapter inflation subjects, with the various products capable of using high pressure carbon dioxide that can be inflated using the injection nozzle 102.

For user convenience, as shown in fig. 1, an external thread is optionally cut on the outer circumference of an adapter collar (adapter) that receives the injection nozzle 102 to further attach hoses and other input nozzles as needed by the user to achieve direct inflation of the adapter inflatable object. The inside of the vaporizing section 103 has a cavity structure in which the capacity can be adjusted. The regulator 104 regulates the volume of the internal cavity of the vaporizer 103 by means of a conventional screw structure and a pressure regulating spring, thereby controlling the flow rate of carbon dioxide. The specific structure of the gasification portion 103 and the regulator 104 will be further described below with reference to the drawings.

Fig. 2A is a plan sectional view of the portable carbon dioxide adapter system 100 shown in fig. 1, and fig. 2B is an exploded block diagram of the portable carbon dioxide adapter system 100 shown in fig. 1. The various component parts of the portable carbon dioxide adapter system 100 shown in fig. 1 and the manner in which they operate are described in detail below in conjunction with the cross-sectional plan view shown in fig. 2A and the exploded view shown in fig. 2B.

As shown in fig. 2A, the components making up the portable carbon dioxide adapter system 100 may be functionally divided into the following components: an adapter collar assembly 11; an injection nozzle valve assembly 12; a gasification/flow conditioning assembly 13; seal ring and retainer assembly 14; a composite drill bit assembly 15 and a gas cylinder collar assembly 16. When the adapter gassing object is being aerated, carbon dioxide enters the portable carbon dioxide adapter system 100 from right to left along the make-up axis direction from the composite bit assembly 15 and is ultimately injected into the adapter gassing object from the injection nozzle valve assembly 12.

Fig. 2B shows structural details of the various components that make up portable carbon dioxide adapter system 100 in a horizontal assembly axis direction further from left to right. As shown in fig. 2B, the adapter collar assembly 11 is comprised of a collar body 111 and a locking pin 112. The collar body 111 has a stepped through hole formed at a left end thereof, the injection nozzle valve assembly 12 is slidably received in the through hole, and a right end of the collar body 111 is connected to the vaporizing/flow adjusting assembly 13 by screwing. Specifically, the right end of the collar body 111 is internally threaded, and the left end of the vaporizing/flow-adjusting unit 13 is correspondingly externally threaded, so that the two are threadedly coupled to each other, and an airtight structure is achieved in a coupled state by means of an O-ring (not shown). The locking pin 112 is used for thread anti-loosening purposes to securely lock the adapter collar assembly 11 to the gasification/flow adjustment assembly 13 during inflation.

The injection nozzle valve assembly 12 is comprised of a nozzle stem 121, an in-line sealing ring 122, an end seal collar 123, an end locking cap 124, and a tension spring 125. The nozzle stem 121 is a stepped cylinder with two end portions having an outer diameter smaller than that of the central portion, the left end of the cylindrical cylinder is a hollow nozzle hole for injecting carbon dioxide gas, the right end of the cylindrical cylinder is a solid screw for connecting the end locking cap 124, the cylindrical cylinder with a large diameter of the central portion is provided with an annular groove for receiving the embedded sealing ring 122, and the embedded sealing ring 122 is used for realizing sliding sealing between the nozzle stem 121 and the adapter collar assembly 11 so as to prevent the carbon dioxide gas from leaking to the outside atmosphere in the inflation process. Further, an intake hole that penetrates all or part of the nozzle stem 121 in the diameter direction and communicates with the nozzle hole is provided between the annular groove and the right end surface of the large-diameter cylindrical body. The end sealing collar 123 abuts against the right end face of the large diameter cylinder of the nozzle stem 121 and is secured by an end locking cap 124, the outer diameter of the end sealing collar 123 being larger than the left end through bore of the adapter collar assembly 11, such that the end sealing collar 123 ensures sealing between the injection nozzle valve assembly 12 and the gasification/flow regulation assembly 13 in a non-inflated condition under the tension of the tension spring 125. The left end of the tension spring 125 is engaged with the right end protrusion of the end locking cap 124, and the right end is abutted against the left end surface of the gasification/flow rate adjustment assembly 13. When the adaptor inflation subject is inflated, as the tension spring 125 is compressed, the seal between the injection nozzle valve assembly 12 and the vaporization/flow rate adjustment assembly 13 is released, and the gas inlet hole of the nozzle stem 121 is exposed, so that high-pressure carbon dioxide gas enters the gas inlet hole and reaches the hollow nozzle hole at the left end of the nozzle stem 121. It will be appreciated by those skilled in the art that by properly positioning the annular groove of the nozzle stem 121 and the maximum compression of the tension spring 125, it is ensured that carbon dioxide simply enters the inlet bore during inflation without breaking the sliding seal of the in-line sealing ring 122.

The vaporizing/flow-adjusting unit 13 is composed of a vaporizing chamber body 131, a flow-adjusting screw 132, a pressure-adjusting spring 133, and a locking screw 134. The gasification chamber main body 131 is a hollow inner cavity structure with a partially threaded hole running through from top to bottom, and meanwhile, a gaseous carbon dioxide outflow hole is formed in the left end face of the gasification chamber main body 131, and a liquid carbon dioxide inflow hole is formed in the right end face of the gasification chamber main body 131, and preferably, the liquid carbon dioxide inflow hole is larger than the gaseous carbon dioxide outflow hole, so that the liquid carbon dioxide is prevented from being blocked or flowing unsmoothly due to surface tension. The left and right ends of the gasification chamber body 131 are externally threaded for connection with the internal threads of the adapter collar assembly 11 and the cylinder collar assembly 16, respectively. Preferably, the left end surface of the gasification chamber body 131 is concave so as to firmly receive the tension spring 125 of the injection nozzle valve assembly 12. The flow rate adjusting screw 132, the pressure adjusting spring 133 and the locking screw 134 are connected or mounted to a partially threaded hole penetrating up and down of the gasification chamber main body 131, and are used to adjust the hollow inner cavity capacity of the gasification chamber main body 131. Preferably, a sealing washer is provided at an end of the flow rate adjusting screw 132, and a sealing piston (not shown) is installed on the pressure adjusting spring 133, both for sealing the gasification chamber body 131, to prevent the gasified carbon dioxide from leaking to the outside. The specific structure and assembly of the various components of the gasification/flow conditioning assembly 13 will be further described below with reference to the drawings.

Seal ring and retainer assembly 14 is comprised of an O-ring 141 and a silicone retainer 142. The O-ring 141 is used to seal between the gasification/flow adjustment assembly 13 and the cylinder liner assembly 16 while preventing the silicone retainer 142 from blocking the liquid carbon dioxide inflow hole on the right end face of the gasification chamber body 131. The silicone retainer 142 cushions the impact force from the composite bit assembly 15, and the central opening of the silicone retainer 142 allows liquid carbon dioxide from the disposable carbon dioxide cylinder to smoothly enter the vaporization/flow adjustment assembly 13.

The composite drill bit assembly 15 is comprised of a drill bit opener 151 and a hollow drill bit holder 152. The hollow bit holder 152 is used to fixedly support the bit opener 151, and the spiral groove shape of the bit opener 151 can ensure that the liquid carbon dioxide smoothly flows to the vaporizing chamber when the disposable carbon dioxide gas cylinder is opened. The hollow bit holder 152 is a hollow cylindrical body having a left end surface abutting the silicone retainer 142 of the seal ring and retainer assembly 14 and a right end surface abutting the inner annular flange of the cylinder collar assembly 16. In use, the drill bit opener 151 carried by the hollow drill bit holder 152 extends from the hollow drill bit holder 152 beyond the internal annular flange of the cylinder collar assembly 16 to open the disposable carbon dioxide cylinder. In addition, alternatively, the hollow bit holder 152 and the bit openers 151 may also adopt an integrated structure instead of the split structure shown in the drawings.

The cylinder collar assembly 16 is made up of a cylinder collar body 161 and a locking pin 162. The left end of the cylinder collar body 161 is threadedly connected to the right end of the vaporization/flow adjustment assembly 13. Likewise, the locking pin 162 serves the purpose of thread lock, securely locking the cylinder collar assembly 16 to the gassing/flow adjustment assembly 13 during the charging process. As previously described, the right end of the cylinder collar body 161 is adapted for connection to a source of carbon dioxide gas, i.e. in threaded engagement to a large volume disposable compressed carbon dioxide cylinder (e.g. CO 2-88G).

Fig. 3 is an explanatory view of a detailed structure of a vaporization/flow rate adjustment part in the portable carbon dioxide adapter system according to the preferred embodiment of the present invention. When the adaptor is charged with a large-capacity disposable carbon dioxide gas cylinder, it is very important to ensure safe release of pressure potential energy and to adjust the gas flow rate. As shown by the arrows in fig. 3, liquid carbon dioxide flows in from the small hole on the left end face of the gasification chamber main body 131, is gasified and expanded in the inner cavity of the gasification chamber main body 131, and then is ejected from the small hole on the right end face of the gasification chamber main body 131 in a gaseous state, and the gasification chamber main body 131 made of a special metal can withstand high-pressure carbon dioxide in strength to ensure safe release of pressure potential energy. In order to adjust the flow rate of the gasified carbon dioxide, through holes (both ends of which are provided with female threads) are formed in the gasification chamber main body 131 in a direction perpendicular to the flow direction of the carbon dioxide indicated by an arrow, and the size of the gasification space inside the gasification chamber main body 131 is adjusted by screwing the flow rate adjusting screw 132 in the through holes, thereby achieving the purpose of adjusting the flow rate of the carbon dioxide. In order to ensure a sealing effect while adjusting the flow rate, a sealing washer is provided at the end of the flow rate adjusting screw 132, and a sealing piston composed of a piston rod 135 with a sealing collar and a piston cap 136 for fixing the sealing collar is fitted above the pressure adjusting spring 133 in the through hole and is brought into contact with the flow rate adjusting screw 132. The locking screw 134 is used to lock the pressure-adjusting spring 133 in the through hole described above. As described above, the sealing piston and the sealing gasket are used for sealing the gasification chamber body 131, and prevent the gasified carbon dioxide from leaking to the outside.

Fig. 4A-4C are schematic views of the use states of the portable carbon dioxide adapter system according to the preferred embodiment of the invention. As shown in fig. 4A to 4C, in the use state, the operator connects one end of the portable carbon dioxide adapter system 100 to the disposable carbon dioxide high-pressure gas cylinder 200 in a screw coupling manner, while the operator presses the other end to the stem of the inlet valve of the object 300 to perform pressurized inflation, and the inflation flow rate can be adjusted by the gasification/flow rate adjustment part, which is very convenient to use. It will be appreciated by those skilled in the art that the inflatable object 300 may be either a gas reservoir within the body of the gun, a fixed gas reservoir attached to the body of the gun, or a variety of products including inflatable 12 gram gas cylinders, and thus it will be appreciated that the portable carbon dioxide adapter system 100 according to the present invention has a wide range of industrial applications and is not limited solely to the soft air gun or air gun industry.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims. It is to be understood that the above description is intended to be illustrative, and not restrictive.
