[0024] Please refer to Figure 1-2 As shown, a pressure gauge 9 is provided on one end of the output end of the gas cylinder 8, and the pressure gauge 9 is fixedly connected to the gun body 1. The pressure gauge 9 is used to detect the pressure inside the gas cylinder 8. The pressure gauge 9 is used to detect the pressure of the compressed air stored in the gas cylinder 8. By judging the pressure value, it is possible to control whether the colored paper has the conditions for spraying. A solenoid valve 11 is provided at the connection between the gas cylinder 8 and the gun rod 5. The solenoid valve 11 is electrically connected to the launch switch 3. The solenoid valve 11 can control the communication between the gas cylinder 8 and the gun rod 5 through the launch switch 3 to control the pressurization in the spray chamber.

[0025] Please refer to Figure 2As shown, a groove 4 is provided on the gun body 1, and the groove 4 passes through the gun body 1. The launch switch 3 is installed in the groove 4. The groove 4 provides an installation space for the launch switch 3. A battery 2 installation groove is provided on one side of the groove 4. A battery 2 is installed in the battery 2 installation groove. The battery 2 provides a power source for the air pump 7 to inject compressed gas into the gas cylinder 8.

[0026] Please refer to Figure 2 As shown, the battery 2 is detachably connected to the battery 2 mounting slot and serves as a handheld portion of the paper spray gun. The battery 2 is provided with a charging interface, and the battery 2 is plug-inly installed in the battery 2 mounting seat to provide power for the air pump 7.

[0028] Please refer to Figure 1-3 As shown, a cover body 6 is provided at one end of the gun barrel 5 away from the gun body 1, the gun barrel 5 has an internal thread, and the cover body 6 is provided with an external thread 12 adapted to the internal thread, the gun barrel 5 is threadedly connected to the cover body 6, when colored paper is stored in the gun barrel 5, since one end of the gun barrel 5 is open, the tilt of the gun barrel 5 causes the colored paper in the gun barrel 5 to fall out, and a cover body 6 is threadedly connected to the gun barrel 5 to limit the material stored in the gun barrel 5 to prevent the colored paper from falling out, wherein the internal thread provided on the gun barrel 5 and the external thread 12 provided on the cover body 6 are utilized to realize the threaded connection between the gun barrel 5 and the cover body 6, and when in use, the cover body 6 is threadedly disassembled to realize adding colored paper into the gun barrel 5.

[0029] Please refer to Figure 3-4 As shown, a baffle 13 is provided in the cover body 6, and a rotating shaft 14 is fixed at both ends of the baffle 13. The baffle 13 is rotatably connected to the inner walls of the two ends of the cover body 6 through the rotating shaft 14. The baffle 13 is rotatably connected in the cover body 6 through the rotating shaft 14, so that the baffle 13 and the cover body 6 are a rotatable structure. However, when the material needs to be sprayed, the baffle 13 is rotated to increase the conduction area between the gun rod 5 and the cover body 6, so as to realize the spraying of colored paper in the gun rod 5.

[0030] Please refer to Figure 4As shown, an adjustment slot is provided on the cover body 6, and an adjustment block 15 is rotatably provided in the adjustment slot, and the adjustment block 15 is fixedly connected to the rotating shaft 14, wherein an adjustment block 15 is fixedly provided on the rotating shaft 14, and the adjustment block 15 is used to rotate the baffle 13.

The adjustment slot is a limited adjustment structure. After adjusting and rotating to a certain angle, it can ensure that the baffle 13 is not affected by the impact force and forces the baffle 13 to rotate. When spraying again, in order to improve the spraying effect of the colored paper, the spraying amount of the colored paper can be controlled by changing the angle of the baffle 13 to improve the visual effect of the spraying.

[0031] Working principle of the utility model

[0032] Remove the cover 6 from the gun barrel 5 by threading, add colored paper into the gun barrel 5, close the cover 6, and rotate the baffle 13 using the adjustment block 15 to make the end surface of the baffle 13 parallel to the end surface of the cover 6, so as to prevent the colored paper from falling out due to the tilt of the gun barrel 5;

[0033] Controlling the transmitting switch 3 enables the battery 2 to provide power to the air pump 7, so that the air pump 7 injects compressed gas into the gas cylinder 8 and stores the compressed gas in the gas cylinder 8. The pressure gauge 9 on one side of the gas cylinder 8 can monitor the pressure value in the gas cylinder 8 in real time and provide real-time feedback to the user;

[0034] Observe the value displayed on the pressure gauge 9 to determine whether the pressure value in the gas cylinder 8 meets the injection requirement. If it meets the requirement, the transmitting switch 3 can be controlled to transmit a signal to the solenoid valve 11. The solenoid valve 11 conducts between the output end of the gas cylinder 8 and the gun rod 5. The compressed gas in the gas cylinder 8 is ejected through its output end. Under the action of the pressure difference, the colored paper in the gun rod 5 is ejected from the gun rod 5, thereby achieving the injection of the colored paper. When the value displayed on the pressure gauge 9 cannot reach the injection requirement, the air pump 7 continues to work to inject compressed gas into the gas cylinder 8. The entire injection time of the compressed gas into the gas cylinder 8 does not exceed 30 seconds.

[0035] When the material in the gun barrel 5 is sprayed, it is necessary to ensure that the baffle 13 releases the limit on the colored paper. The baffle is rotated by rotating the adjustment block 15, and the conduction area of the baffle 13 can be adjusted according to the actual spraying amount. When the end face of the baffle 13 is perpendicular to the end face of the cover body 6, the amount of colored paper dispensed by the gun barrel 5 is at its maximum. The material stored in the gun barrel 5 is subjected to the compressed gas in the gas cylinder 8 and is sprayed out at high speed, creating colorful visual effects for various celebrations to add to the joyful atmosphere.
