[0038] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of an intelligent timer circuit provided in an embodiment of the present application is shown in FIG. Figure 2 The present invention provides a schematic diagram of an overload detection circuit, a relay circuit, an on-off control circuit and a photosensitive circuit in an embodiment of the present invention. The intelligent timer circuit can be applied to the field of timers to enable the timer to have multiple functional effects to meet the diverse usage needs of consumers and improve the user experience. The intelligent timer circuit 100 includes a step-down circuit 110, a main control circuit 120, an overload detection circuit 130, a relay circuit 140, a photosensitive circuit 150 and an on-off control circuit 160.

[0039] Among them, the step-down circuit 110 is used to connect with the power supply 20, and is respectively connected to the main control circuit 120, the relay circuit 140 and the photosensitive circuit 150, so as to step down the voltage of the power supply 20 and send it to the main control circuit 120, the relay circuit 140 and the photosensitive circuit 150 respectively; the overload detection circuit 130 is used to connect with the power supply 20 and the load 30 respectively, and is connected to the main control circuit 120, and is used to send a first feedback signal to the main control circuit 120 when the current exceeds a preset load range; the relay circuit 140 is connected to the overload detection circuit 130 to control the operation of the load 30; the photosensitive circuit 150 is connected to the main control circuit 120 to generate a second feedback signal according to the ambient brightness and send it to the main control circuit 120; the main control circuit 120 is connected to the on-off control circuit 160 to send a control signal to the on-off control circuit 160 according to the received first feedback signal or the second feedback signal; the on-off control circuit 160 and the relay circuit 140 are used to control the operation of the relay circuit 140 according to the control signal.

[0040] Exemplarily, the power supply 20 sends the voltage to the step-down circuit 110, and the step-down circuit 110 steps down the voltage and sends it to the main control circuit 120, the relay circuit 140 and the photosensitive circuit 150 respectively for their operation. In a normal state, the relay of the relay circuit 140 is in an energized state, and the load 30 is energized to work. When the overload detection circuit 130 detects that the current exceeds the preset load range, that is, the output power value output to the load 30, the overload detection circuit 130 can generate a first feedback signal and send it to the main control circuit 120, and the photosensitive circuit 150 can sense the current in real time. The main control circuit 120 generates a control signal according to the first feedback signal or the second feedback signal when the preset ambient brightness value is reached, and sends it to the on-off control circuit 160.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
