Description

Technical Field

[0001] The utility model relates to the technical field of hot melt glue guns, in particular to a novel hot melt glue gun. Background Art

[0002] A hot melt glue gun is an electric tool that melts glue sticks for gluing and bonding. Traditional hot melt glue guns are powered by a 220V circuit connected to the power cord, and the high voltage electricity connected to the gun body is connected to the electric heating tube in the gun body. After the electric heating tube is powered on, the glue stick is melted and then squeezed out from the gun nozzle; the traditional hot melt glue gun is not only limited by the power cord during use, but the voltage connected to the gun body is also much higher than the safe voltage that the human body can withstand. Once an unexpected situation occurs and leakage occurs, it will affect the life safety of the user, and the gun nozzle exposed during use may also cause skin burns. Therefore, a new type of hot melt glue gun is designed to solve the above problems. Utility Model Content

[0023] First, remove the leak-proof cover 2 on the outside of the gun mouth 4 and the partition shield 5, and then turn on the power switch 93 at the grip 12 of the gun body 1 to make the power supply component 9 inside the gun body 1 heat the ceramic heating tube 3. No external power cord is required for power supply during the entire use process;

[0024] When bonding, first insert the glue stick from the feed port at the rear end of the gun barrel 11, and pull the trigger 7 to drive the glue feeding mechanism 8 to drive the glue stick into the ceramic heating tube 3, so that the ceramic heating tube 3 melts the glue stick, and the melted liquid glue flows out from the gun nozzle 4 under the push of the glue stick, so that the bonding work can be carried out. During use, the outer edge of the gun nozzle 4 is covered by the partition shield 5, which reduces the volume of the gun nozzle 4 leaking out of the gun body 1, thereby preventing the gun nozzle 4 from scalding the skin during use;

[0025] When the glue gun is not in use, the leak-proof cover 2 is placed outside the gun mouth 4 and the partition shield 5 to prevent the internal liquid glue from flowing out and causing pollution;
