Description

Water bomb toy gun ballistic top spin control structure

The present invention relates to a ballistic top-spin control structure for a water bomb, and in particular, to a ballistic top-spin control structure for a water bomb toy gun that can steplessly adjust the pressure force against the water bomb and increase the upward rotation speed after the water bomb breaks away.

BB shot is a spherical projectile used for firing toy guns. The common material is plastic. Whether it is a pneumatic or electric toy gun, excessive driving power will still cause the BB shot to produce a safe explosion. Doubts. Therefore, some industries have developed BB bullets made of hydrogel material, generally called hydrogel balls, "water bullets or gel beads".

Water bombs are also cheaper than plastic bombs and paint bombs, and they are also lighter to carry (they can be packed in plastic bottles or bags in a dry state and soaked in water for a few hours before use); and water bombs exceed 98 % of the mass and volume are composed of water molecules. The residue formed after the impact target is broken will turn into a fine powder that naturally decomposes after the water evaporates. It does not have the environmental cleanup problem caused by plastic pollution like airsoft bullets, and it is not like paint. If you do that, oil paint will remain.

Because water bullets are very fragile and will break inside the gun once the chamber pressure is too high, water bullets cannot use spring pressure to push into the gun chamber like plastic bullets; early water bullets used the same top as paintball guns. An ammunition feeder (usually disguised as a scope) is installed and gravity is used to feed water bombs into the gun chamber. Although some operators have developed a lower-mounted magazine with a built-in motor, which is powered by the battery of the gun body through the contact point, driving a gear to push the accumulation of water bombs up the supply tube and into the gun, the structure of this motor is too complex and easier to Due to the accidental rupture of the water bomb, problems such as short circuit and electric leakage may occur. After the water bomb ruptures, the gel may dry out and cause the gear to become stuck.

Therefore, some industry players have developed "water gun top-spin device" such as Chinese Patent Application No. 202021127343.1. The upper inner wall of the patent's top-spin element is provided with a first slot along the length direction. The inside of the first slot is along the length direction. A friction plate is provided, and one end of the friction plate close to the barrel is connected to the bottom of the first slot; the side of the friction plate corresponding to the axis of the barrel is in the same curved surface as the inner wall of the barrel; the friction plate corresponds to one side of the axis of the barrel. There is a friction pattern on the side to generate friction against the water bomb; the friction plate causes the water bomb to produce directional rotation during the process of exiting the chamber, so that the parabolic trajectory of the water bomb's original flight is corrected to a relatively straight line.

However, the above-mentioned patent actually still has many shortcomings, that is, after the water bomb continuously contacts the friction pattern, the surface will actually produce considerable wear. Although the water bomb is a gel substance, after a short period of continuous friction, the water bomb will break away from the friction plate. The volume when it enters the friction plate must actually be smaller than the volume before it enters the friction plate. Therefore, the friction between the water bomb and the friction plate will become smaller and smaller (according to the movement route of the water bomb), and the directional rotation speed of the water bomb will also decrease.

At the same time, the water bullet is continuously in contact with the friction pattern of the friction plate. Therefore, the water bullet itself has two kinds of kinetic energy, the kinetic energy of displacement toward the muzzle, and the kinetic energy of directional rotation. Based on the above mentioned water bullets, the water bullet continues to contact the friction pattern. , after the kinetic energy of the water elastic displacement comes into contact with the friction pattern, in addition to continuing to be converted into directional rotation kinetic energy, the kinetic energy of the displacement will continue to be consumed during the friction process, because the surface of the water elasticity contains water, which cannot be provided by the friction pattern alone. Enough friction prevents the water bomb from effectively increasing the speed of directional rotation and consumes most of the kinetic energy.

In view of the above-mentioned shortcomings of conventional use, the inventor researched ways to improve the above-mentioned shortcomings, and finally came up with the present invention.

The main purpose of the present invention is to provide a ballistic spin control structure for a water bomb toy gun capable of continuously adjusting the elastic force of the compressed water.
