[0022] A lithium battery hot melt gun that can be quickly cooled after discharging glue comprises a gun body 1, a cylindrical portion 11 is fixedly provided on the front side of the gun body 1, a glue discharging nozzle 12 is fixedly provided on the front side of the cylindrical portion 11, a conveying pipe 13 is fixedly provided on the rear side of the gun body 1, a ring member 2 is sleeved on the cylindrical portion 11, a battery box 4 is fixedly connected to one side of the ring member 2, a lithium battery 8 is embedded and fixed inside the battery box 4, a cooling box 5 is fixedly connected to the other side of the ring member 2, a cooling fan 7 is fixedly installed side by side inside the cooling box 5, and by driving the cooling fan 7 to rotate, air can be supplied to the hot melt after discharging glue, thereby accelerating the air flow at the hot melt, thereby accelerating the heat dissipation at the hot melt, and making the hot melt after discharging glue able to be quickly cooled. Ventilation windows 51 are provided on the cooling box 5 on the front and rear sides of the cooling fan 7. A button switch 6 is fixedly provided on the top of the cooling box 5. The button switch 6, the cooling fan 7 and the lithium battery 8 are electrically connected by wires. When in use, the glue stick can be inserted into the gun body 1 through the conveying pipe 13, and the glue stick is heated and melted by the heating structure inside the gun body 1. By pulling the trigger at the lower part of the gun body 1, the hot melt can be ejected from the glue nozzle 12. During this process, the cooling fan 7 can be turned on by the button switch 6. At this time, the cooling fan 7 rotates to supply air toward the ejected hot melt, accelerates the air flow at the hot melt, thereby accelerating the heat dissipation at the hot melt, and allows the hot melt to cool quickly after being ejected.

[0023] The locking lever 32 is fixedly secured to the locking cam 31 and secured to the cam 32 by means of a spring 33. The locking lever 32 is secured to the locking cam 31 and secured to the cam 32 by means of a spring 33. The locking lever 32 is secured to the locking cam 31 and secured to the cam 32 by means of a spring 33. The locking lever 32 is secured to the locking cam 31 and secured to the cam 32 by means of a spring 33. The locking cam 31 is then released to lock the locking cam 32 so that the locking cam 32 is in the locked position and the locking cam 33 is in the locked position.

[0024] Working principle: When in use, the glue stick can be inserted into the gun body 1 through the delivery pipe 13, and the glue stick can be heated and melted by the heating structure inside the gun body 1. By pulling the trigger at the bottom of the gun body 1, the hot melt glue can be ejected from the glue nozzle 12. During this process, the cooling fan 7 can be turned on by the button switch 6. At this time, the cooling fan 7 rotates to supply air toward the ejected hot melt glue, accelerating the air flow at the hot melt glue, thereby accelerating the heat dissipation at the hot melt glue, and allowing the hot melt glue to cool down quickly after being ejected. Before holding the gun body 1 for glue application, the angle of the cooling box 5 can be adjusted according to the glue application path so that the cooling box 5 can be adjusted correctly. To supply air to the ejected hot melt, when adjusting the angle of the cooling box 5, the sliding handle 31 can be manually pushed backward to drive the front end of the limiting rod 32 to move out of the limiting socket 21, and the spring 33 can be compressed to rotate the ring 2. After adjusting the cooling box 5 to a suitable angle, the sliding handle 31 is released. At this time, under the elastic force of the spring 33, the front end of the limiting rod 32 can be driven to be reinserted into the corresponding limiting socket 21, and the ring 2 is locked, and the angle of the cooling box 5 can be quickly adjusted, so that the cooling box 5 can supply air directly to the ejected hot melt, so that the hot melt can be cooled quickly.
