1. A multi-gas-source heater, comprising:
a main shell;
a pipeline system arranged on said main shell and having a first communication state applied to high calorific value gas and a second communication state applied to low calorific value gas, wherein the high calorific value gas defines liquefied petroleum gas or propane, and the low calorific value gas defines natural gas or artificial gas;
a temperature-sensing valve arranged on said main shell and connected to said pipeline system, said temperature-sensing valve being capable of regulating flow of an output gas;
a burner arranged on said main shell, wherein said burner includes a first nozzle and a second nozzle, said first nozzle and said second nozzle being both connected to the pipeline system, said first nozzle being applicable to the high calorific value gas, and said second nozzle being applicable to the low calorific value gas;
an ignition apparatus connected to said burner and capable of igniting said burner; and
a switching valve arranged on said main shell and connected to said pipeline system, said switching valve being capable of switching said pipeline system between said first communication state and said second communication state;
wherein when said switching valve switches said pipeline system to said first communication state, said first nozzle outputs the gas;
wherein when said switching valve switches said pipeline system to said second communication state, said second nozzle output the gas, or said first nozzle and said second nozzle both output the gas;
said main shell including a pressure stabilizing valve connected to said pipeline system, said pressure stabilizing valve being capable of outputting the gas at a stable pressure, said pressure stabilizing valve having a first pressure stabilizing state applied to the high calorific value gas and a second pressure stabilizing state applied to the low calorific value gas;
said pressure stabilizing valve including a first shell, a second shell, a diaphragm, a pressure stabilizing rod, an elastic assembly, and a regulating assembly;
said first shell having a gas inlet channel and a gas outlet channel;
said diaphragm being connected between said first shell and said second shell;
said diaphragm being hermetically connected to said first shell to form a first cavity;
said diaphragm being hermetically connected to said second shell to form a second cavity;
said gas inlet channel and the gas outlet channel being both in communication with said first cavity;
said regulating assembly being connected to said second shell;
said elastic assembly being connected to said regulating assembly and being configured to engage said diaphragm;
said pressure stabilizing rod being connected to said diaphragm;
said diaphragm being deformable and extendable to drive said pressure stabilizing rod to move relative to said first shell;
said pressure stabilizing rod being configured, cooperatively with a gas outlet of said gas inlet channel, to regulate a ventilation capacity;
said regulating assembly being configured to regulate an elastic force of said elastic assembly when engaging said diaphragm, so as to switch said pressure stabilizing valve between said first pressure stabilizing state and said second pressure stabilizing state;
said switching valve including a linkage member;
said the linkage member being connected to said regulating assembly, and when said switching valve switches said pipeline system between said first communication state and said second communication state, said switching valve is linked with said regulating assembly through said linkage member.
