Shooting structure of a paint bullet gun

Abstract

A shooting structure of a paint bullet gun. The paint bullet gun includes a main body and a handle. A gunlock and a controlling unit are disposed in the main body. An air source serves to fill air into the main body. A trigger is disposed in the handle for controlling the controlling unit to control the gunlock to reciprocally move within the main body. An activating chamber is formed in the main body. The activating chamber communicates with the air source via a vent. One end of the activating chamber communicates with a barrel. A bullet-dropping port is disposed on the activating chamber near the barrel to communicate with the activating chamber. The gunlock is disposed in the activating chamber. A space is defined between outer circumference of middle section of the gunlock and inner wall of the activating chamber. The space is movable along with the reciprocally movable gunlock to be aligned with the vent. One end of the gunlock is connected with the controlling unit. An air passage is formed in the gunlock. One end of the air passage extends out of the other end of the gunlock opposite to the controlling unit. The other end of the air passage extends to communicate with the space.

1 . A shooting structure of a paint bullet gun, the paint bullet gun including a main body and a handle, a gunlock and a controlling unit being disposed in the main body, an air source serving to fill air into the main body, a trigger being disposed in the handle for controlling the controlling unit, the controlling unit serving to control the gunlock to reciprocally move within the main body so as to control a paint bullet to drop into the main body and control the air of the air source for shooting the paint bullet, said shooting structure being characterized in that an activating chamber is formed in the main body, the activating chamber communicating with the air source via a vent, one end of the activating chamber communicating with a barrel, a bullet-dropping port being disposed on the activating chamber near the barrel to communicate with the activating chamber, the gunlock being disposed in the activating chamber, the gunlock being a bar body, a space being defined between outer circumference of middle section of the gunlock and inner wall of the activating chamber, the space being movable along with the reciprocally movable gunlock to be aligned with the vent, one end of the gunlock being connected with the controlling unit for controlling the gunlock to reciprocally move within the activating chamber, an air passage being disposed in the gunlock, one end of the air passage extending out of the other end of the gunlock opposite to the controlling unit, the other end of the air passage extending to communicate with the space.  
   
   
       2 . The shooting structure of the paint bullet gun as claimed in  claim 1 , wherein an air reservoir is disposed in the main body in parallel to the activating chamber, the air source supplying air for the air reservoir, the activating chamber communicating with the air reservoir via the vent, the handle being disposed under the air reservoir of the main body, a controlling IC and a cell for supplying power being further disposed in the handle, a touch-controlled switch being connected between the trigger and the controlling IC, the controlling IC being connected with the controlling unit for controlling the same.  
   
   
       3 . The shooting structure of the paint bullet gun as claimed in  claim 2 , wherein the controlling unit includes an electromagnetic valve and a piston body, the electromagnetic valve being mounted on one side of the air reservoir of the main body, intake lines communicating the electromagnetic valve with the air reservoir and the piston body, the electromagnetic valve being also connected with the controlling IC in the handle for controlling the electromagnetic valve to control intake of the lines, the piston body being disposed at one end of the activating chamber opposite to the barrel, a rear cap fixing the piston body and sealing the activating chamber, the piston body having an internal piston room two ends of which respectively communicate with a first intake passage and a second intake passage, the first and second intake passages further respectively communicating with the intake lines of the electromagnetic valve, a piston rod being disposed in the piston room, one end of the piston rod extending out of the piston body to fixedly connect with one end of the gunlock opposite to the air passage, the other end of the piston rod being positioned in the piston body and having a push block, the intake of the first and second intake passages being variable to axially move the push block within the piston room, whereby the piston rod is driven by the push block to drive the gunlock to reciprocally move within the activating chamber.  
   
   
       4 . The shooting structure of the paint bullet gun as claimed in  claim 1 , wherein an annular groove is formed on outer circumference of the middle section of the gunlock, whereby the space is defined between the annular groove and the inner wall of the activating chamber, the other end of the air passage extending to a section of the gunlock, where the annular groove is formed, the wall of the section being formed with several radial through holes communicating the air passage with the space.  
   
   
       5 . The shooting structure of the paint bullet gun as claimed in  claim 4 , wherein several  0 -rings are inlaid in outer circumference of the gunlock to airtight abut against inner wall of the activating chamber for avoiding leakage of air.
