Abstract: A heating apparatus with automatic switching heaters includes a control module, a switch module, and a heating module. The control module receives an input power source. The switch module is connected to the control module. The heating module is connected to the switch module. When the control module detects that an amplitude of the input power source is larger than a threshold voltage value, the control module turns on a first switch assembly and turns off a second switch assembly of the switch module so that the heating module operates in a first heating mode. When the control module detects that the amplitude of the input power source is less than the threshold voltage value, the control module turns on the first switch assembly and the second switch assembly of the switch module so that the heating module operates in a second heating mode.

Abstract: An axial fan includes a fan frame, an impeller and a motor. The fan frame has a frame body, a base and plural connecting members. The base is disposed at the center of a side of the frame body. The connecting members connect the frame body to the base. The impeller is accommodated in the frame body and disposed on the base. The impeller has a rotating shaft, a hub and plural blades disposed around the hub. The motor is disposed on the base and connects with the rotating shaft to drive the impeller to rotate. When the impeller rotates forwardly, the airflow is induced to flow through the connecting members, blades, and one side of the frame body away from the base. When the impeller rotates reversely, the airflow is induced to flow through the side of the frame body, blades and connecting members.
