[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 The utility model provides a technical solution: a high-stability long-distance liquid supply gun, including a handle 10, a main body 20, a cavity 30, a pipeline 301, a storage bag 302, a hose 303, a discharge pipe 304, a screw rod 305, a pressing plate 306, a discharge port 40, a switch 50, a spring 501, a connecting belt 502, an air bag 503, a moving plate 504 and an air inlet pipe 505;

[0032] The long-distance liquid supply gun prevents the liquid from dripping from the discharge port 40. The specific implementation method is as follows:

[0033] A pressing mechanism is installed on the surface of the handle 10, and the pressing mechanism includes: a switch 50 is rotatably installed on the surface of the handle 10, and a spring 501 is installed on the surface of the switch 50, and the end of the spring 501 is connected to the surface of the handle 10, a connecting belt 502 is fixedly connected to the surface of the switch 50, an air bag 503 is installed at the bottom of the main body 20, and a shift plate 504 is slidably installed at the bottom of the main body 20, and the surface of the shift plate 504 is connected to the connecting belt 502, an air inlet pipe 505 is installed on the surface of the air bag 503, and the air inlet pipe 505 passes through the shift plate 504 and is inserted into the inside of the discharge port 40, one end of the switch 50 is rotatably connected to the handle 10, and the other end of the switch 50 is chain-connected with the spring 501, and the switch 50 can control the valve to open, the surface of the shift plate 504 fits with the surface of the air bag 503, and the air bag 503 is through-connected to the discharge port 40 through the air inlet pipe 505, and the shift plate 504 is slidably connected to the main body 20.

[0034] The switch 50 is pressed to turn on the liquid supply device. At this time, the switch 50 rotates on the surface of the handle 10, and the switch 50 presses the spring 501 to shrink the spring 501. At this time, the switch 50 drives the connecting belt 502 to move, and the connecting belt 502 drives the shifting plate 504 to move on the surface of the main body 20. The shifting plate 504 squeezes the airbag 503 to shrink the airbag 503. At this time, the gas and liquid inside the airbag 503 enter the air inlet pipe 505 and enter the discharge port 40 through the air inlet pipe 505. When the switch 50 is closed, the spring 501 pushes the bottom of the switch 50 to move outward, and the pulling force of the switch 50 on the connecting belt 502 and the shifting plate 504 disappears. At this time, the squeezing of the airbag 503 disappears, and the airbag 503 expands, allowing air to enter the interior of the air inlet pipe 505. The gas drives the excess material at the discharge port 40 to move to the interior of the air inlet pipe 505, and the liquid and air enter the interior of the airbag 503 through the air inlet pipe 505 to prevent the excess material at the discharge port 40 from dripping.

[0035] The long-distance liquid supply gun is easy to adjust and increases the stability of liquid transportation. The specific implementation method is as follows:

[0036] The handle 10 is set as a cylindrical structure, and one end of the handle 10 is fixedly connected to the main body 20; a discharge port 40 is installed on the surface of the main body 20, and an adjustment mechanism is arranged inside the main body 20, and the adjustment mechanism includes: a cavity 30 is embedded inside the main body 20, a pipe 301 is installed on one end of the surface of the main body 20, and one end of the pipe 301 is inserted into the main body 20 and arranged inside the cavity 30, a storage bag 302 is installed inside the cavity 30, and one end of the storage bag 302 is connected to the pipe 301, and the other end of the storage bag 302 is fixedly connected to a hose 303, the end of the hose 303 is connected to a discharge pipe 304, and the end of the discharge pipe 304 is connected to the discharge port 40, and a screw rod 305 is rotatably connected to the surface of the main body 20, and the screw rod 305 The end of the body 20 is inserted into the cavity 30 and is connected with a pressure plate 306, the interior of the main body 20 is provided with a thread, and the main body 20 is threadedly connected to the screw rod 305, the hose 303 is provided with a flexible structure, and the end of the pressure plate 306 is in contact with the surface of the hose 303, the pressure plate 306 is provided with an arc structure, the end of the pressure plate 306 is in contact with the inner wall of the cavity 30, and the cavity 30 and the pressure plate 306 are slidingly connected, the discharge port 40 and the pipe 301 are symmetrically arranged at both ends of the main body 20, and the end of the pipe 301 is connected with an opening, the pipe 301 and the storage bag 302 are through-connected, and the storage bag 302 and the hose 303 are through-connected, the hose 303 and the discharge pipe 304 are through-connected, and the diameter of the discharge pipe 304 is smaller than the diameter of the storage bag 302.

[0037] When the switch 50 is pressed, the liquid enters the interior of the pipe 301 through the liquid supply device, and enters the interior of the storage bag 302 through the pipe 301. The liquid enters the discharge port 40 through the storage bag 302 and the discharge pipe 304 in sequence, and the liquid is discharged through the discharge port 40. When the distance of the liquid needs to be adjusted, the handheld screw 305 is rotated, and the screw 305 moves along the thread inside the main body 20, so that the screw 305 moves toward the inside of the main body 20. The screw 305 pushes the pressure plate 306 to move downward inside the cavity 30, and the bottom of the pressure plate 306 squeezes the hose 303 downward to shrink the hose 303. The diameter of the hose 303 becomes smaller, and the path through which the liquid passes becomes narrower, which can increase the pressure on the liquid, so that the liquid passes through the hose 303 more quickly, accelerates the liquid, and at this time increases the distance of the liquid.

[0038] Working principle: When using the high-stability long-distance liquid supply gun, a screw rod 305 and a pressure plate 306 are provided to facilitate adjustment thereof and increase the stability of liquid transportation. An air bag 503, a shift plate 504 and an air inlet pipe 505 are provided to prevent liquid from dripping from the discharge port 40, thereby increasing the overall practicality.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
