That is, in this embodiment, when the controller detects that there is no power signal at any of the ports X1, X2, and X3, it indicates that none of the ports X1, X2, and X3 is connected to the closed-loop circuit at this time, and then the controller controls the fans M1 and M2 to operate at the first lower wind speed at this time. When the controller detects that the port X1 has an electric signal and the ports X2 and X3 both have no electric signal, the representation shows that the port X1 is connected to the closed-loop circuit at the moment, and the ports X2 and X3 are not connected to the closed-loop circuit, so that the controller controls the fans M1 and M2 to still operate at the lower first wind speed at the moment. When the controller detects that the ports X1 and X3 have electric signals and the port X2 does not have electric signals, the fact that the ports X1 and X3 are connected into the closed-loop circuit at the moment is represented, and the port X2 is not connected into the closed-loop circuit at the moment, the controller controls the fans M1 and M2 to operate at a second higher wind speed. When the controller detects that the port X2 has an electric signal and the ports X1 and X3 have no electric signal, the representation shows that the port X2 is connected into the closed loop circuit at the moment, and the ports X1 and X3 are not connected into the closed loop circuit, and then the controller controls the fans M1 and M2 to operate at a second higher wind speed at the moment. When the controller detects that the ports X1 and X2 have electric signals and the port X3 does not have electric signals, the representation ports X1 and X2 are connected into the closed loop circuit, and the port X3 is not connected into the closed loop circuit, at the moment, the controller controls the fans M1 and M2 to operate at a first lower wind speed. When the controller detects that the ports X1, X2 and X3 all have electric signals, the closed loop circuit is accessed to the ports X1, X2 and X3 at the moment, and then the controller controls the fans M1 and M2 to operate at a second higher wind speed.
In order to control the wind speed of the fan more accurately, the system of this embodiment further includes: a transformer; the input end of the transformer is electrically connected with the controller, and the output end of the transformer is electrically connected with the fan. On the premise of adopting the structure and the connection mode, the controller of the embodiment adopts the following mode to control the fan to operate at the wind speed corresponding to the gear instruction: and controlling the transformer to output a driving voltage corresponding to the gear instruction based on the gear instruction so as to enable the fan to operate at a wind speed corresponding to the driving voltage.
In other words, in the present embodiment, the transformer is controlled to output different voltages to control the fan to operate at different wind speeds.
In order to realize better heating and cooling effects of the electric heater, the number of the fans is two; the two fans are connected in parallel.
In order to simplify the system structure, the transformer and the controller in this embodiment are integrated on a printed circuit board, forming a power board for supplying voltage to the fans M1 and M2.
In order to make the electric heater possess higher security performance, the system described in this embodiment further includes: a microswitch S1; the gear switch is connected to a power supply through the microswitch S1, and the microswitch S1 is used for: and when the electric heater is detected to be off the ground or toppled, the gear switch is powered off.

The microswitch mainly plays a role in safety protection.
In order to further make the electric heater possess higher security performance, the system described in this embodiment further includes: a temperature control switch S2; the gear switch is through temperature detect switch S2 is connected to the power, just temperature detect switch S2 is used for: when the temperature of the preset area is detected to be greater than a preset temperature threshold value, the gear switch is powered off; and when the temperature of the preset area is not larger than the preset temperature threshold value, the gear switch is powered on.
Specifically, the temperature control switch is a power-off reset temperature limiter, and in practical application, a 75 ℃ temperature limiter can be adopted and has the function of safety protection. The principle is that when the local temperature of the temperature limiter placement area exceeds 75 ℃, the temperature limiter starts to work to disconnect the circuit to stop the product from working, and when the temperature of the product falls below 75 ℃, the temperature limiter resets to reconnect the circuit.
In order to make the electric heater more effective and energy-saving to realize the heating function, the heating component described in this embodiment is a PTC (Positive Temperature Coefficient) heating element.
