Claim of US Patent No. 10,716,170

1. A heating apparatus with automatic switching heaters, the heating apparatus comprising:a control module configured to receive an input power source;
a switch module connected to the control module, and the switch module comprising:
a first switch assembly connected to the control module and the heating module; and
a second switch assembly connected to the control module and the heating module; and
a heating module connected to the switch module;
wherein when the control module is configured to detect that an amplitude of the input power source is greater than a threshold voltage value, the control module is configured to output a control signal to control the switch module, and the switch module is configured to switch the heating module to operate in a first heating mode, the control module is configured to turn on the first switch assembly and turn off the second switch assembly; when the control module is configured to detect that the amplitude of the input power source is less than the threshold voltage value, the control module is configured to output the control signal to control the switch module, and the switch module is configured to switch the heating module to operate in a second heating mode, the control module is configured to turn on the first switch assembly and the second switch assembly;
wherein in the second heating mode, the control unit is configured to turn on the second switch assembly and then turn on the first switch assembly.
