Air gun barrel and its spray gun device

The present invention provides a barrel of an air spray gun and a spray gun device thereof, and particularly a pressurizing device for spraying a liquid outward from a water pipe through a negative pressure state inside the barrel, and a water pipe is disposed through a lumen space of the barrel. Then, the gas transmission system is connected, and a negative pressure state is generated through the negative pressure pipe on the other side of the barrel to inhale the outside air and pressurize the air flow speed to achieve the purpose of diffusing the liquid through the water pipe.

Please refer to the side view of the prior art spray gun as shown in the seventh figure. The spray gun A is composed of a grip A1, a T-tube A2, a liquid cylinder A3 and a spray pipe B, and The spray pipe member B comprises a bell tube B1. The bell tube B1 is provided with a screw seat B11 at one end thereof, and is screwed to the pressure air outlet end A4 of the spray gun A. The outer end of the bell tube B1 is open, and the pressure at the spray gun A is The thread at the center of the air outlet end A4 is screwed to the joint C1 at the end of the water supply pipe C. Then, the spray gun A is input to the outside high pressure air from the grip A1, and then transmitted to the pressure air outlet end A4 via the T-tube A2. And the high-pressure air and the water in the liquid cylinder A3 are taken out by the Venturi effect at the nozzle C2, and after the nozzle C2 is mixed with the high-pressure air, the nozzle C2 of the water supply pipe C is sprayed outward to pass through the air pressure. The returning spray gun A performs the spraying operation; however, the conventional spray gun A is connected to the external high-pressure air at the grip A1 for the high-pressure air to take the liquid in the liquid tank A3 at the nozzle C2 and then enters the flared tube B1 of the sprayed pipe member B. Through The high-pressure air is quickly sent out through the bell tube B1, and the liquid inside the water supply pipe C is sprayed outward from the nozzle C2, but the high-pressure air supplied by the high-pressure air source connected to the spray gun A directly enters the T-tube A2, and The T-shaped tube A2 has a three-way tubular shape, and only high-pressure air can be introduced at the grip A1 for the high-pressure air to be sent into the bell tube B1 from the outlet end A4 and then released to the outside, but the high-pressure air is flushed into the T-tube A2 and After the inside of the bell tube B1, it is limited by the tube space of the spray gun A, and the introduction of external high-pressure air is limited, and the force of the high-pressure air gas to the outlet end A4 and the joint C1 is not large, causing the gas to be flushed outward.
