[0032] As Figs. 1 to 3As shown, a gas heater includes a shell 1, a control valve assembly 2, an air inlet pipeline assembly 3, a porous ceramic burner 4, an ignition pipeline assembly 5, a combustion-supporting pipeline assembly 6, an oxygen-deficiency protection device 7, an ignition device 8 and a tipping protection device 40. The control valve assembly 2 is arranged on the shell 1, specifically on the top end of the shell 1, which is convenient for adjustment and mainly responsible for adjusting the gas flow to achieve precise control. The air inlet pipeline assembly 3 is connected with the air inlet of the control valve assembly 2 to ensure that the gas is supplied as needed. The porous ceramic burner 4 is arranged in the shell 1, and the inside of the porous ceramic burner 4 is filled with regularly arranged holes. This structure greatly reduces the resistance of the holes, effectively increases the contact area of the gas and air, promotes complete combustion, improves thermal efficiency and reduces harmful gas emissions. The shell 1 is provided with a heating port 11 corresponding to the position of the porous ceramic burner 4 on the front side, which is used to release heat to the external environment, and has a tank body mounting groove 12 for mounting a gas tank 30 which can be clamped in communication with the air inlet pipeline assembly 3, facilitating the installation and replacement of the gas tank 30. The ignition pipeline assembly 5 and the combustion-supporting pipeline assembly 6 are connected with the control valve assembly 2 respectively, which can continuously provide stable gas to support the combustion process, form a double-path gas supply and ensure the stability and efficiency of combustion. The ignition pipeline assembly 5 has an ignition jet nozzle 51 close to the porous ceramic burner 4 for initial ignition. The oxygen-deficiency protection device 7 is electrically connected with the control valve assembly 2 and close to the ignition jet nozzle 51, and is used to send instructions to the control valve assembly 2 to automatically cut off the gas supply. Preferably, the oxygen-deficiency protection device 7 includes a thermocouple. The oxygen-deficiency protection device 7 (ODS) determines whether the oxygen content in the air is sufficient by monitoring the change of the flame temperature. When it is detected that the oxygen concentration in the combustion area is insufficient, the device immediately sends instructions to the control valve assembly 2, and the control valve assembly 2 automatically cuts off the gas supply, effectively preventing backfire or incomplete combustion caused by oxygen deficiency and ensuring safety in use. The ignition device is arranged close to one side of the ignition jet nozzle 51.
