Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to a shooting structure of
a paint bullet gun. In the paint bullet gun, a gunlock is
controlled to move forward or backward to control the drop of the
paint bullet as well as control the intake of the air for shooting
the paint bullet.
[0002] The shooting structures of the conventional paint bullet
guns can be substantially divided into mechanical type and
electronic type. A mechanical type or electronic type of trigger
unit is used to control a striker and a gunlock for
unblocking/blocking a bullet-dropping port. The striker controls a
valve for taking the air into the gunlock for shooting the paint
bullet dropping into the barrel of the paint bullet gun.
[0003] The conventional structure is quite complicated and has high
failure ratio. In addition, the processing and assembling cost of
the conventional paint bullet gun is very high. Therefore, a
simplified structure of the paint bullet gun has been developed as
shown in FIG. 5. The paint bullet gun 6 has a barrel 60 and a
handle 9. An activating chamber 61 and a gun chamber 62 are formed
in the barrel 60 to communicate with each other. A bullet-dropping
port 63 is formed on the bullet tunnel 62, whereby a paint bullet
can drop through the port 63 into the gun chamber 62. A pneumatic
cylinder 64 is disposed in the activating chamber 61 near the gun
chamber 62. A movable rod 65 is disposed in the pneumatic cylinder
64 for unblocking/blocking the bullet-dropping port 63. The movable
rod 65 has an internal passage 651. An air reserving body 7 and a
valve 8 are sequentially arranged in the activating chamber 61 near
the pneumatic cylinder 64. A rear cap 66 seals rear end of the
activating chamber 61. The air reserving body 7 has an air
reservoir 71. One end of the air reservoir 71 is tapered to form an
air passage 72 extending into the passage 651 of the movable rod
65. A valve rod 81 is disposed in the valve body 8. The valve rod
81 is controlled by the valve body 8 to move back and forth. A plug
82 is disposed at front end of the- valve rod 81 for
unblocking/blocking a section communicating the air reservoir 71
with the air passage 72. The valve rod 81 is formed with an
internal tunnel 83 communicating with the air reservoir 71. The
rear cap 66 has an internal tunnel 661 one end of which
communicates with the tunnel 83 of the valve rod 81. The other end
of the tunnel 661 communicates with an air source. A trigger 91 is
disposed in the handle 9 for controlling an IC board 92 for
controlling the valve rod 81 of the valve body 8 to move back and
forth.
[0004] By means of operating the trigger 91 of the handle 9, the
valve rod 81 of the valve body 8 can be controlled to move forward,
making the plug 82 block the section communicating the air
reservoir 71 with the air passage 72. At this time, the air goes
through the tunnel 83 of the valve rod 81 into the air reservoir 71
to push the movable rod 65 forward so as to block the
bullet-dropping port 63. The trigger 91 can be also operated to
retreat the valve rod 81. At this time, the plug 82 unblocks the
section communicating the air reservoir 71 with the air passage 72.
Under such circumstance, the air in the air reservoir 71 can go
through the air passage 72 to shoot the paint bullet dropping into
the gun chamber 62. After shooting the paint bullet, the movable
rod 65 will move backward, permitting a second paint bullet to drop
into the gun chamber 62 for next shot.
[0005] In the above paint bullet gun, the structure is simplified.
However, the valve rod 81 for controlling intake of the air and the
movable rod 65 for controlling blocking/unblocking of the
bullet-dropping port are still separate components. This still
leads to high processing and assembling cost.
[0006] Furthermore, the pneumatic cylinder 64 with the movable rod
65, the valve body 8 with the valve rod 81, the air reserving body
7 and the rear cap 66 are sequentially mounted into the activating
chamber 61 of the barrel 60. When removing a broken bullet, it is
necessary to detach the rear cap 66, the valve body 8, the air
reserving body 7 and the pneumatic cylinder 64 one by one. This
procedure is quite inconvenient.
[0007] Besides, the valve rod 81 for controlling intake of the air
and the movable rod 65 for controlling blocking/unblocking of the
bullet-dropping port are separate components. In the case that any
of the two components fails, it will become impossible for the
paint bullet gun to shoot the paint bullet. Therefore, the ratio of
failure of the conventional paint bullet gun is higher.
SUMMARY OF THE INVENTION
[0008] It is therefore a primary object of the present invention to
provide a shooting structure of a paint bullet gun. The paint
bullet gun includes only one single gunlock serving to
unblock/block the bullet-dropping port and control the intake of
the air for shooting the paint bullet. Therefore, the structure of
the paint bullet gun is simplified and the manufacturing and
assembling cost is greatly lowered. In addition, the ratio of
failure of the paint bullet gun is reduced.
[0009] It is a further object of the present invention to provide
the above shooting structure of the paint bullet gun. In the case
that a broken bullet needs to be removed, a user only needs to
unscrew the rear cap and take out the gunlock to remove the broken
bullet. Therefore, it is quite convenient to disassemble the
structure for removing the broken bullet.
[0010] According to the above objects, the shooting structure of
the paint bullet gun of the present invention 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. The controlling unit serves 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. 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. The gunlock is a bar body. 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 for
controlling the gunlock to reciprocally move within the activating
chamber. An air passage is disposed 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Please refer to FIGS. 1 to 4. The present invention is
related to a shooting structure of a paint bullet gun. The paint
bullet gun has a main body 1 in which a gunlock 2 is disposed. The
gunlock 2 is controlled by a controlling unit 3 to move back and
forth for controlling loading of the paint bullets and controlling
the air for shooting the paint bullets.
[0018] An activating chamber 11 and an air reservoir 12 are
parallelly arranged in the main body 1. The activating chamber 11
communicates with the air reservoir 12 via a vent 15. An air source
fills air into the air reservoir 12. One end of the activating
chamber 11 communicates with a barrel 13. A bullet-dropping port 14
is disposed on the activating chamber 11 near the barrel 13 to
communicate with the activating chamber 11. A paint bullet 5 can be
dropped and loaded into the activating chamber 11. The gunlock 2 is
disposed in the activating chamber 11 and controlled by the
controlling unit 3 to reciprocally move within the activating
chamber 11. The controlling unit 3 is mounted in the main body
1.
[0019] A handle 4 is disposed under the air reservoir 12 of the
main body 1. In the handle 4 are arranged a trigger 41, a
controlling IC 42 and a cell 43 for supplying power. A
touch-controlled switch 44 is connected between the trigger 41 and
the controlling IC 42. The controlling IC 42 is connected with the
controlling unit 3 for controlling the same.
[0020] The gunlock 2 is a bar body slidably mounted in the
activating chamber 11. An annular groove 21 is formed on outer
circumference of middle section of the gunlock 2. A space 21a is
defined between the annular groove 21 and inner wall of the
activating chamber 11. One end of the gunlock 2 is connected with
the controlling unit 3. An air passage 22 is disposed in the
gunlock 2. One end of the air passage 22 extends out of the other
end of the gunlock 2 opposite to the controlling unit 3. The other
end of the air passage 22 extends to a section of the gunlock 2,
where the annular groove 21 is formed. The wall of this section is
formed with several radial through holes 23 communicating the air
passage 22 with the space 21a. Several O-rings 24 are inlaid in
outer circumference of the gunlock 2 to airtight abut against inner
wall of the activating chamber 11 for avoiding leakage of air.
[0021] In this embodiment, the controlling unit 3 includes an
electromagnetic valve 31 and a piston body 32. The electromagnetic
valve 31 is mounted on one side of the air reservoir 12 of the main
body 1. Intake lines communicate the electromagnetic valve 31 with
the air reservoir 12 and the piston body 32. In addition, the
electromagnetic valve 31 is connected with the controlling IC 42 in
the handle 4 for controlling the electromagnetic valve 31 to
control intake of the lines. The piston body 32 is disposed at one
end of the activating chamber 11 opposite to the barrel 13. A rear
cap 33 fixes the piston body 32 and seals the activating chamber
11. The piston body 32 has an internal piston room 321 two ends of
which respectively communicate with a first intake passage 322 and
a second intake passage 323. The first and second intake passages
322, 323 further respectively communicate with the intake lines of
the electromagnetic valve 31. A piston rod 324 is disposed in the
piston room 321. One end of the piston rod 324 extends out of the
piston body 32 to fixedly connect with one end of the gunlock 2
opposite to the air passage 22. The other end of the piston rod 324
is positioned in the piston body 32 and has a push block 325. The
intake of the first and second intake passages 322, 323 is variable
to axially move the push block 325 within the piston room 321. The
piston rod 324 is driven by the push block 325 to drive the gunlock
2 to reciprocally move within the activating chamber 11.
[0022] Referring to FIGS. 3 and 4, in a ready state, the
electromagnetic valve 31 of the controlling unit 3 will control the
first intake passage 322 of the piston body 32 to take in the air.
At this time, the piston rod 324 drives the gunlock 2 to retreat,
making front end of the gunlock 2 move backward away from the
bullet-dropping port 14. Under such circumstance, a paint bullet 5
is dropped to the front end of the gunlock 2 into a ready state.
When pulling the trigger 41 of the handle 4 to trigger the
touch-controlled switch 44, the controlling IC 42 controls the
lines of the electromagnetic valve 31 to take in the air, whereby
the air goes from the second intake passage 323 of the piston body
32 into the piston room 321 for pushing the piston rod 324 to drive
the gunlock 2 forward. At this time, the front end of the gunlock 2
blocks the bullet-dropping port 14 to avoid leakage of air and
prevent a second paint bullet 5 from dropping so as to avoid clog.
Under such circumstance, the annular groove 21 of the gunlock 2
will be moved along with the forwarded gunlock 2 to the vent 15,
whereby the air in the air reservoir 12 will go through the vent 15
into the space 21a and then go through the through holes 23 into
the air passage 22 to shoot the paint bullet 5 in front of the
front end of the gunlock 2. After shooting the paint bullet 5, the
electromagnetic valve 31 of the controlling unit 3 will further
control the first intake passage 322 of the piston body 32 to take
in the air. At this time, the piston rod 324 drives the gunlock 2
to retreat, making the front end of the gunlock 2 move backward
away from the bullet-dropping port 14. Under such circumstance, a
second paint bullet 5 is dropped to the front end of the gunlock 2
into a ready state. Accordingly, the shooting operation can be
circularly repeated. Therefore, the paint gun can continuously
shoot the paint bullets 5. The controlling IC 42 serves to control
the intake time of the lines of the electromagnetic valve 31 so as
to control the staying time of the forwarded piston rod 324 of the
piston body 32. Accordingly, the staying time of the forwarded
gunlock 2 can be controlled. Therefore, the time for which the air
passage 22 of the gunlock 2 communicates with the vent 15 is
controllable. Accordingly, the intake of the air going from the air
reservoir 12 into the air passage 22 is controllable. Therefore,
the speed at which the paint bullet 5 is shot can be controlled as
required.
[0023] In the above shooting structure of the paint bullet gun of
the present invention, one single gunlock is used to unblock/block
the bullet-dropping port and control the intake of the air going
into the air passage for shooting the paint bullet. The structure
of the present invention is simplified and the manufacturing and
assembling cost is greatly lowered.
[0024] Moreover, in the case that a broken bullet needs to be
removed, a user only needs to unscrew the rear cap and take out the
gunlock to remove the broken bullet. Therefore, it is quite
convenient to disassemble the structure for removing the broken
bullet.
[0025] The above embodiment is only used to illustrate the present
invention, not intended to limit the scope thereof. Many
modifications of the above embodiment can be made without departing
from the spirit of the present invention.
