Description

TECHNICAL AREA

[0001] The present invention relates to the technical field of air pistols, in particular an air pistol using high-pressure gas. STATE OF THE ART

[0002] Air pistols typically use high-pressure gas as a propellant to fire the air pistol pellets.

[0003] Conventional air pistols use gas exclusively for firing. After high-pressure gas is introduced into the air valve of the air pistol, the firing pin strikes the valve stem, opening the air valve and allowing it to function normally. The air valve expels high-pressure gas that propels the pellet forward, with some of the high-pressure gas flowing backward into a cylinder of a slide, rapidly pushing the slide backward and resetting the firing pin. However, air pistols typically require a gas cylinder as a source of high-pressure gas. The high-pressure gas supplied by the cylinder is used not only to propel the pellet forward but also to retract the firing pin. Since the capacity of the gas cylinder is limited, it cannot supply gas continuously. With each shot, the pressure in the gas cylinder decreases, which impairs the retraction of the firing pin during the firing process.Furthermore, the function is slightly weather-dependent: at low temperatures the pressure drops further, which impairs stability during use.

DETAILED DESCRIPTION

[0017] With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. Figure 8 provides an embodiment of the present utility model, an air gun using high-pressure gas, wherein the air gun using high-pressure gas comprises a first main body 100, an air valve assembly 200, and a drive assembly 300, wherein the first main body 100 is provided with a cavity 101; wherein the air valve assembly 200 is provided in the cavity 101; wherein the air valve assembly 200 comprises a valve body 210 and a valve rod 220; wherein the valve rod 220 is slidably guided through the valve body 210 along a first direction; wherein both ends of the valve rod 220 are, in the first direction, a first end 221 and a second end 222, wherein the first end 221 of the valve rod 220 is located at least partially outside the valve body 210, and wherein the second end 222 of the valve rod 220 is provided with an air outlet opening 243;wherein the drive arrangement 300 is provided in the cavity 101; wherein the drive arrangement 300 comprises a first elastic element 310, a hammer 320 and an electric drive element 350; wherein the hammer 320 is located on one side of the valve body 210 and the hammer 320 is opposite an end section of the first end 221 of the valve stem 220 in the first direction; wherein the first elastic element 310 is connected to the hammer 320 and an inner wall of the cavity 101, and wherein the first elastic element 310 has an elastic restoring force which moves the hammer 320 in a direction towards the valve body 210 and the valve stem 220 in the first direction; wherein the electric drive element 350 is connected to the impact hammer 320 and can intermittently move the impact hammer 320 away from the valve body 210 in the first direction.

[0018] In this embodiment of the present utility model, the ball 10 can be positioned at the air outlet opening 243 of the valve stem 220. Since the electric drive element 350 can intermittently move the impact hammer 320 in a first direction away from the valve body 210, when the electric drive element 350 moves the impact hammer 320 in the first direction away from the valve body 210, the impact hammer 320 and the valve stem 220 are separated from each other.When the electric drive element 350 stops moving the impact hammer 320 in the first direction away from the valve body 210, the first elastic element 310 can move the impact hammer 320 in a direction towards the valve stem 220. This allows the impact hammer 320 to strike the valve stem 220, triggering the normal function of the valve stem 220 and causing the high-pressure gas in the valve body 210 to escape through the air outlet opening 243 of the valve stem 220 to drive the ball 10 forward. In contrast to conventional air guns, where some of the high-pressure gas is required to reset the impact hammer 320, the air gun, using high-pressure gas via the electric drive element 350, moves the impact hammer 320 intermittently in a direction away from the valve body 210 to ensure stable reset of the impact hammer 320.This ensures better stability when used in low-temperature environments and also saves high-pressure gas from the gas cylinder, thus improving the utilization of the high-pressure gas.

[0019] In particular, the projectiles fired and used by the air pistol using high-pressure gas are metallic and non-metallic projectiles; the electrical drive elements may be a spindle motor structure, an electromagnetic structure, or other electrically controlled structures that can drive the movement of the hammer.

[0020] With reference to Fig. 2, Fig. 3 and Fig. In some embodiments of the present utility model, the electric drive element 350 comprises a motor 351, a drive gear 352, and an interval gear 353; wherein the drive gear 352 and the interval gear 353 are both rotatably arranged in the cavity 101 about the first direction; wherein the interval gear 353 comprises a first gear hub 354 and a first tooth 355; wherein the first tooth 355 is provided on a circumferential side of the first gear hub 354; wherein the first gear hub 354 is provided on a side of the drive gear 352 and is connected to a side end of the drive gear 352; wherein a second tooth 321 is provided on the impact hammer; wherein the motor 351 is connected to the drive gear 352 in a drive manner and can drive the drive gear 352 in rotation, wherein the first tooth 355 of the interval gear 353 engages intermittently with the second tooth 321.

[0021] Since the first gear hub 354 of the interval gear 353 is located on the side of the drive gear 352, the interval gear 353, after the electric drive element 350 has set the drive gear 352 in rotation, can be rotated in the first direction so that the first tooth 355 engages with the second tooth 321 of the impact hammer 320. The interval gear 353 then continues to rotate, moving the impact hammer 320 in the direction away from the valve body 210 and compressing the first spring element 310 until the first tooth 355 and the second tooth 321 separate.The first elastic element 310 pushes the impact hammer 320 in the direction facing the valve stem 220, causing it to strike the valve stem 220. This moves the end section of the valve stem 220, located outside the valve body 210, into the interior of the valve body 210, triggering the gas valve and releasing the high-pressure gas in the valve body 210 from the gas outlet opening 243 of the valve stem 220. Subsequently, the electric drive element 350 continuously rotates the drive gear 352 until the first tooth 355 of the interval gear 353 engages with the second tooth 321, moving the impact hammer 320 in the direction away from the valve body 210 to reset it.

[0022] In particular, the electric drive element 350 rotates the drive gear 352, which in turn rotates the interval gear 353. This causes the first tooth 355 to remain in an inactive state between the second tooth 321 for most of a revolution of the interval gear 353, allowing the impact hammer 320 time to strike the valve rod 220. When the first tooth 355 engages with the second tooth 321, the impact hammer 320 can be moved and reset.

[0023] With reference to Fig. 3 and Fig. In some embodiments of the present utility model, three first teeth 355 are provided, arranged at intervals around the circumferential side of the first gear hub 354, while two second teeth 321 are arranged at intervals along the first direction. The gap between the two second teeth 321 corresponds to the gap between two adjacent first teeth 355.

[0024] Once the impact hammer 320 is in contact with the valve body 210 and the valve stem 220, the rotation of the interval gear 353 causes the first tooth 355 to contact the second tooth 321 and thus engage; further rotation of the interval gear 353 then causes all three first teeth 355 and both second teeth 321 to engage with each other. The arrangement of three first teeth 355 and two second teeth 321 increases the stability of the engagement.

[0025] With reference to Fig. 2, Fig. 3 and Fig. In some embodiments of the present utility model, the impact hammer 320 comprises a hammer body 330 and an impact block 340; wherein the second tooth 321 is provided at a lower end of the hammer body 330; wherein the hammer body 330 is hollow internally; wherein both side ends of the hammer body 330 are each provided with a first opening and a second opening 322 along the first direction, the first opening and the second opening 322 both being connected to the interior of the hammer body 330; wherein the impact block 340 is provided inside the hammer body 330 and connected to the hammer body 330, the impact block 340 being located at least partially at the first opening, and the impact block 340 bearing against the first end 221 of the valve rod 220;wherein one end of the first elastic element 310 rests against one end of the striking block 340 facing away from the first opening, while the other end of the first elastic element 310 is passed through the second opening 322 and rests against the inner wall of the cavity 101.

[0026] The first elastic element 310 can move the striking block 340 to move the hammer body 330, with the striking hammer 320 bearing against the first end 221 of the valve rod 220 via the striking block 340 to strike and move the valve rod 220. The striking hammer 320 bears against the valve body 210 via the hammer body 330. Since the first elastic element 310 is connected to the striking block 340, the striking block 340 can achieve a damping effect after impacting the valve rod 220 via the first elastic element 310.

[0027] The second tooth 321 is located at the lower end of the hammer body 330. The first tooth 355 of the interval gear 353 can engage with the second tooth 321 at the lower end of the hammer body 330 to move the hammer body 330 via the interval gear 353 in the direction away from the valve body 210 and to move the striking block 340 in the direction away from the valve stem 220.

[0028] In particular, sliding rails are provided on the two opposite inner side walls of the cavity 101, the sliding rails extending along the first direction; sliding grooves are provided on both side ends of the hammer body 330, the sliding grooves extending continuously along the first direction; the two sliding grooves of the hammer body 330 are each located outside the two sliding rails.

[0029] The arrangement of the slide rails and the sliding grooves allows the direction of movement of the hammer body 330 to be limited, which in turn limits the direction of movement of the impact hammer 320 and improves the stability of the impact hammer 320 when striking the valve rod 220.

[0030] With reference to Fig. In some embodiments of the present utility model, a projection structure 341 is provided on an end section of the striking block 340, wherein the projection structure 341 is provided at the first opening, and wherein an end surface of the projection structure 341, which abuts the first end 221 of the valve rod 220, is flush with an end surface of the hammer body 330, on which the first opening is provided, thereby improving stability during striking.

[0031] In particular, the cross-section of the projection structure 341 is larger than or equal to the cross-section of the valve rod 220, so that the valve rod 220 can project into the first opening and an unintentional collision of the hammer body 330 with the valve rod 220 is avoided.

[0032] With reference to Fig. 3 and Fig. In some embodiments of the present utility model, the drive arrangement 300 further comprises transmission gears 360; wherein several transmission gears 360 are provided, all of which are rotatably mounted in the cavity 101; wherein the several transmission gears 360 mesh successively, one transmission gear 360 engaging with the motor 351 and another transmission gear 360 engaging with the drive gear 352. The arrangement of several transmission gears 360 establishes a drive connection between the motor 351 and the drive gear 352, so that the motor 351 can drive the drive gear 352 into rotation during operation.

[0033] With reference to Fig. In some embodiments of the present utility model, the air valve arrangement 200 further comprises a second elastic element 250; wherein the second elastic element 250 is connected to the valve body 210 and the valve rod 220 and has an elastic restoring force which moves the valve rod 220 in a direction towards the impact hammer 320.

[0034] The arrangement of the second elastic element 250 achieves a restoring effect on the valve rod 220.

[0035] In particular, the second elastic element 250 can be a spring structure mounted outside the valve rod 220, wherein a gradually enlarging, umbrella-like structure is provided on the circumferential side of the valve rod 220; one end of the second elastic element 250 rests against the umbrella-like structure, while the other end of the second elastic element 250 rests against the inner wall of the air intake chamber 211.

[0036] With reference to Fig. 3 and Fig. In some embodiments of the present utility model, the valve body 210 is provided with a first through-hole, a second through-hole, and an air intake chamber 211; wherein the first through-hole and the second through-hole are each provided at the two side ends of the valve body 210 along the first direction and opposite each other, and both are connected to the air intake chamber 211; wherein the air intake chamber 211 is used to receive high-pressure gas; wherein the valve stem 220 comprises a first stem body 230 and a second stem body 240; wherein an end section of the first stem body 230 is connected to an end section of the second stem body 240; wherein an end of the first stem body 230 facing away from the second stem body 240 forms the first end 221 of the valve stem 220;wherein an end of the second rod body 240 facing away from the first rod body 230 forms the second end 222 of the valve rod 220; wherein the first rod body 230 is slidably guided through the first passage opening in the first direction, wherein the second rod body 240 is slidably provided in the second passage opening in the first direction; wherein a cross-section of the second rod body 240 is larger than a cross-section of the first rod body 230; wherein the second rod body 240 is provided with an air outlet channel 241 and an exhaust opening 242; wherein the exhaust opening 242 is provided at an end section of the second rod body 240, which is connected to the first rod body 230 and is connected to the air outlet channel 241, wherein the end section of the second rod body 240, which is provided with the exhaust opening 242, is located in the air intake chamber 211;wherein the second elastic element 250 has an elastic restoring force which moves the valve rod 220 in a direction towards the impact hammer 320, and causes the end section of the second rod body 240, which is provided with the exhaust opening 242, to abut an inner wall of the air intake chamber 211, wherein the first passage opening and the second passage opening are provided opposite each other in the first direction.

[0037] When the impact hammer 320 strikes the first rod body 230 of the valve rod 220 to move the second rod body 240, the end section of the second rod body 240, which is provided with the exhaust opening 242, is separated from the inner wall of the air intake chamber 211, so that the high-pressure gas in the air intake chamber 211 can pass through the exhaust opening 242 into the air outlet duct 241.The high-pressure gas is then released through the air outlet opening 243, whereby the impact of the impact hammer 320 on the valve rod 220 causes the venting and the ejection of the ball 10; when the impact hammer 320 moves in the direction away from the valve body 210, the second elastic element 250 can move the valve rod 220 in the direction towards the impact hammer 320 and causes the end section of the second rod body 240, which is provided with the exhaust opening 242, to rest against the inner wall of the air intake chamber 211, thereby closing the exhaust opening 242 again.

[0038] In particular, the second elastic element 250 is designed as a spring structure, wherein the spring structure is mounted on the second rod body 240 and is connected to the inner wall of the air intake chamber 211 and to the second rod body 240; wherein the end section of the first rod body 230 is formed in one piece with the end section of the second rod body 240.

[0039] With reference to Fig. 2, Fig. 4 and Fig. In some embodiments of the present utility model, the air pistol using high-pressure gas further comprises a pistol body 400 and a loading assembly 500; wherein the pistol body 400 is hollow inside; wherein the first main body 100, the drive assembly 300, the loading assembly 500 and the air valve assembly 200 are all provided inside the pistol body 400; wherein the loading assembly 500 comprises a loading rod element 510, an ejection tube element 520 and a third elastic element; wherein the loading rod element 510 is provided with a first channel 511 extending continuously in the first direction; wherein the ejection tube element 520 is provided with a second channel 521 extending continuously in the first direction; wherein the discharge pipe element 520 is located on one side of the loading rod element 510, and wherein an end opening of the second channel 521 is provided opposite an end opening of the first channel 511;wherein the loading rod element 510 can be slidably provided in the first direction within the pistol body 400; wherein the second rod body 240 can be slidably guided through the first channel 511 in the first direction; wherein the air outlet opening 243 is connected to the first channel 511; wherein the third elastic element is connected to the loading rod element 510 and has an elastic restoring force that moves the loading rod element 510 in a direction towards the ejection tube element 520; wherein the electric drive element 350 is drive-connected to the loading rod element 510 and can intermittently move the loading rod element 510 in a direction away from the ejection tube element 520 in order to achieve the return of the loading rod element 510.

[0040] The ejection tube element 520 is located on one side of the loading rod element 510 in the first direction, allowing the balls 10 to be positioned between the loading rod element 510 and the ejection tube element 520. The third elastic element can intermittently move the loading rod element 510 in the direction facing the ejection tube element 520, thereby moving the ball 10 located between the loading rod element 510 and the ejection tube element 520 in the direction facing the ejection tube element 520 and thus effecting the loading process.

[0041] The high-pressure gas in the valve body 210 can escape from the air outlet channel 241 and the air outlet opening 243 of the valve stem 220.
