A glue gun includes a shell, a burner, a mixture chamber, a barrel and a dispenser. The burner is disposed in the shell and formed with a combustion chamber and a thermal chamber. The mixture chamber is connected to the combustion chamber. The barrel is inserted through the thermal chamber. The dispenser is connected to the barrel. Gas is mixed with air in the mixture chamber. The mixture is sent into the combustion chamber from the mixture chamber. Heat is generated as the mixture is ignited and combusted in the combustion chamber. The thermal chamber transfers the heat to the barrel from the combustion chamber. The barrel heats and melts a glue stick inserted therein. The dispenser dispenses the molten glue from the barrel.
