air gun

Abstract

This invention discloses an air gun, relating to the field of air gun technology. The air gun includes a main body, an air valve assembly, and a drive assembly. The main body has a cavity; the air valve assembly is disposed within the cavity; a valve stem is slidably inserted into the valve body along a first direction; a striking rod is a magnetic conductor; the striking rod is located on one side of the valve stem, and one end of the striking rod is positioned opposite to the first end of the valve stem in the first direction; an electromagnetic drive unit connected to the striking rod can control the frequency of the striking rod's back-and-forth movement along the first direction. When using a gas cylinder with a higher internal pressure, the electromagnetic drive unit can increase the frequency of the striking rod's back-and-forth movement along the first direction, which can better utilize the inflation effect of the gas cylinder with a higher internal pressure. When using a gas cylinder with a lower internal pressure, the electromagnetic drive unit can decrease the frequency of the striking rod's back-and-forth movement along the first direction, providing time for the gas in the gas cylinder to fill the air valve, ensuring the effectiveness of each gas ejection from the air valve.

Claims

1. An air gun, characterized in that it comprises: The main body has a cavity. A valve assembly is disposed within the cavity; the valve assembly includes a valve body and a valve stem; the valve stem is slidably inserted into the valve body along a first direction; the two ends of the valve stem along the first direction are a first end and a second end, respectively, and both the first end and the second end of the valve stem are at least partially located outside the valve body, with an air outlet provided at the second end of the valve stem; a drive assembly is disposed within the cavity; the drive assembly includes a striking rod and an electromagnetic drive component; the striking rod is a magnetic conductor; the striking rod is located on one side of the valve stem, and one end of the striking rod is positioned opposite to the end of the first end of the valve stem in the first direction; the electromagnetic drive component is connected to the striking rod and is capable of driving the striking rod to move forward along the first direction and push the valve stem to move along the first direction, and to move backward along the first direction until separated from the valve stem, and is capable of controlling the frequency of the striking rod's back-and-forth movement along the first direction.

2. An air gun as claimed in claim 1, further comprising a projectile pushing assembly; the projectile pushing assembly is movably disposed within the cavity along a first direction; the striking rod is connected to the projectile pushing assembly; the electromagnetic drive is capable of driving the striking rod to move back and forth along the first direction, and driving the projectile pushing assembly to move back and forth.

3. An air gun as claimed in claim 2, wherein the projectile pushing assembly includes a connecting rod and a projectile pushing rod; both ends of the connecting rod are respectively connected to the projectile pushing rod and the striking rod; the projectile pushing rod is provided with a first through groove extending in a first direction; the projectile pushing rod is movably sleeved on the second end of the valve rod in the first direction through the first through groove, and the air outlet is connected to the first through groove.

4. An air gun as claimed in claim 3, wherein a limiting groove is provided on the inner wall of the cavity; the limiting groove extends along a first direction; a limiting block is provided on the side end of the connecting rod along a second direction, the limiting block being slidably disposed within the limiting groove; the second direction is perpendicular to the first direction.

5. An air gun as claimed in claim 3, wherein the connecting rod includes a rod body and a first connecting plate; the first connecting plate is connected to the striking rod; the first connecting plate is provided with a first through-hole disposed along a first direction, and the first connecting plate is sleeved on the striking rod through the first through-hole.

6. An air gun as claimed in claim 5, wherein the striking rod is provided with a first annular groove; the first connecting plate is sleeved on the periphery of the first annular groove through the first through-hole; and the first connecting plate is at least partially located within the first annular groove.

7. An air gun as claimed in claim 6, wherein the first annular groove extends along a first direction, and the inner wall of the first opening abuts against the peripheral wall of the first annular groove; the length of the first annular groove in the first direction is greater than the length of the first connecting plate in the first direction.

8. An air gun as claimed in claim 7, wherein a first annular boss is provided on the periphery of the striking rod; the electromagnetic drive includes an electromagnetic core; the electromagnetic core is provided with a sliding groove extending in a first direction; one end of the striking rod away from the air valve assembly is slidably inserted into the sliding groove; the striking rod is slidable until the first annular boss abuts against the electromagnetic core.

9. An air gun as claimed in claim 8, wherein a second annular boss is provided on the periphery of the striking rod; the second annular boss and the first annular boss are spaced apart in a first direction, and the second annular boss and the first annular boss define a first annular groove; both the first annular boss and the second annular boss are at least partially opposite to the first connecting plate.

10. An air gun as claimed in claim 8, wherein the groove is disposed through a first direction; the distance between the first annular boss and the end of the striking rod away from the air valve assembly is less than or equal to the length of the groove.
