Description
Technical Field

[0002] The car heater includes a heating component, a water pump and a storage component. When working, the water pump draws external liquid into the storage component and then heats it up by the heating component. Some existing car heaters and radiators are controlled independently. There may be a situation where the heater starts working without turning on the radiator. If the heater is turned on continuously without turning on the radiator, the heat generated by the heater cannot be released and accumulates inside and around the heater. The heat cannot be fully utilized, resulting in continuous fuel waste. Summary of the invention
[0003] In order to solve the problem that the radiator is forgotten to be turned on due to the existing radiator and heater control circuit working independently, the utility model proposes an automobile heater and a radiator control circuit.

[0005] The output end of the second switch is connected to the control end of the heating device, and the heating device is connected to the power supply to form a loop.
[0006] When the first switch is controlled to be closed, the heat dissipation module is powered on and the diode is turned on to power on the second switch. After the second switch is powered on, the second switch is controlled to power on the heating device. When the first switch is not closed, the circuit of the heating device cannot be powered on by the second switch, thereby realizing the sequential operation of the heat dissipation module and the heating device.
[0007] Furthermore, the first switch includes a two-speed output switch, and the first switch is provided with a first output end and a second output end.

[0010] The first heat sink and the second heat sink are connected in parallel and are electrically connected to the second output end of the first switch to form a loop.
[0011] Further, the diode includes a first diode and a second diode, the anode of the second diode is connected to the first output terminal, and the cathode is connected to the second switch;
[0012] The anode of the first diode is connected to the second output terminal, and the cathode of the first diode is connected to the second switch.

After the first switch is closed, the diode is turned on and the second switch is powered on. At this time, the second switch is manually controlled, and the second switch powers on the heating device to work. The problem that the heat is not fully utilized when the heater works alone is effectively solved. In addition, the circuit structure of the utility model is simple, the reliability is high, and it is not easily interfered by other devices. BRIEF DESCRIPTION OF THE DRAWINGS
