Compared to the food processor circuit shown in <FIG>, the solar module <NUM> of the food processor circuit <NUM> shown in <FIG> comprises output terminals SolarE+ and SolarGND used for outputting electrical energy and connected with the power receiving circuit <NUM>. The food processor circuit <NUM> comprises an energy storage unit <NUM> connected in parallel with the output terminals SolarE+ and SolarGND of the solar module <NUM>.

<FIG> shows a schematic view of another embodiment of the food processor circuit <NUM>. The food processor circuit <NUM> shown in <FIG> is similar to the food processor circuit <NUM> shown in <FIG>. Compared to the food processor circuit shown in <FIG>, the main control module <NUM> of the food processor circuit <NUM> shown in <FIG> is used to control the lightening state of the light source <NUM>, so that the solar module <NUM> generates a corresponding electrical signal to control the power receiving circuit <NUM>.

The main control module <NUM> controls the light source <NUM> to turn on during the second duration and then turn off during the first duration, indicating the other control signal among a high level and a low level. Thus, a more accurate control is achieved by the different combinations of turning on and off of the light source <NUM> indicating different control signals. In other examples, the combinations of turning on and off of the light source <NUM> can be different than the above-described example.

In another embodiment, the main control module <NUM> controls the light source <NUM> to change from being turned on to being turned off, indicating one control signal among a high level and a low level. The main control module <NUM> controls the light source <NUM> to change from being turned off to being turned on, indicating the other control signal among a high level and a low level. Thus, control is achieved by different changes of being turned on and off of the light source <NUM> indicating different control signals.

In an embodiment, the indicator light circuit <NUM> may comprise a plurality of light-emitting diodes D101-<NUM> of different colors. The plurality of light-emitting diodes D101-<NUM> may be connected to different ports of a sub-control module <NUM>. The sub-control module <NUM> controls the turning on and off of the light-emitting diodes D101-<NUM>.

In an embodiment, the indicator light circuit <NUM> is connected to the solar module <NUM>, which powers the indicator light circuit <NUM>. In an embodiment, the negative pole of the light-emitting diode D101-<NUM> is connected to the sub-control module <NUM>, and the positive pole is connected to the positive output terminal SolarE+ of the solar module <NUM> via a resistor R101-R103.

In the embodiment shown in <FIG>, a capacitor C1 is connected in series between a signal receiving port Sig of the sub-control module <NUM> and the solar module <NUM>. The capacitor C1 can absorb a peak voltage of the voltage output by the solar module <NUM>, so as to smooth out the voltage output to the signal receiving port Sig of the sub-control module <NUM>. Thus, the signals of high and low level received by the sub-control module <NUM> are clearer, reducing the probability of erroneous identification of high and low levels and increasing control accuracy. The capacitor C1 is connected in series between the positive output terminal SolarE+ of the solar module <NUM> and the signal receiving port Sig of the sub-control module <NUM>.

In an embodiment, the capacitor C1 is connected in series with a current limiting resistor R1. The current limiting resistor R1 is connected in series between the signal receiving port Sig of the sub-control module <NUM> and the solar module <NUM>. It can be used to limit current, preventing the current output by the solar module <NUM> from being excessive.

In an embodiment, the food processor circuit <NUM> comprises a unidirectional conduction unit <NUM>. The capacitor C1 is connected between the unidirectional conduction unit <NUM> and the solar module <NUM>. The current limiting resistor R1 is connected between the unidirectional conduction unit <NUM> and the solar module <NUM>. The unidirectional conduction unit <NUM> can prevent current from reversing direction when the voltage of the solar module <NUM> is low, which would cause the level detected at the signal receiving port Sig of the sub-control module <NUM> to be abnormal and result in a control error.
