[0002] Some existing electronic devices need to be equipped with dry batteries, which are powered by the voltage of dry batteries directly. However, when the battery power of dry battery equipment is used to less than 2.5V (2 batteries), the performance of dry battery equipment will be reduced, resulting in unstable operation of the equipment, and even failure to operate normally.

[0030] For ease of understanding, the process of optimizing the use of dry cell power by the circuit 10 for optimizing the use of battery power of the present invention is described as follows:
[0031] First, a battery V1 is installed in the circuit, and the battery voltage may be 1 to 3.0V, for example, a battery voltage of 1.2V. The battery voltage is divided by the first voltage-dividing resistor R11 and the second voltage-dividing resistor R12 to the non-inverting input terminal of the operational amplifier U1. The operational amplifier U1 enables the operational comparison amplification function, and the output terminal of the operational amplifier U1 outputs a high level. The first capacitor C1 is charged through the second resistor R3, the third resistor R7 and the first diode D3. At the same time, the high level output by the output terminal of the operational amplifier U1 raises the voltage of the non-inverting input terminal of the operational amplifier U1 through the first resistor R4. When the voltage of the first capacitor C1 is charged to a voltage higher than the voltage of the non-inverting input terminal of the operational amplifier U1, the output terminal of the operational amplifier U1 flips and outputs a low level. At this time, the voltage of the non-inverting input terminal of the operational amplifier U1 is pulled down by the first resistor R4 through the low level of the non-inverting input terminal of the operational amplifier U1. At the same time, the voltage of the first capacitor C1 is delayed discharged by the low level of the non-inverting input terminal of the operational amplifier U1 through the second resistor R3. In this process, there is a time difference of the second resistor R3*the first capacitor C1 between the levels of the non-inverting input terminal and the inverting input terminal of the operational amplifier U1.
[0032] Then, the oscillation signal generated at the output end of the operational amplifier U1 allows the first transistor Q1 to generate an oscillating switch signal through the fourth resistor R10, and the switch signal forms a BOOST boosting effect through the inductor L1 and the second diode D1 to boost the battery voltage to a boost voltage. The boost voltage forms a relatively stable direct current through the energy storage of the second capacitor C2 and the third capacitor C3. Among them, the third capacitor C3 can filter the boost voltage. Finally, the voltage Vout after energy storage filtering is used as a power supply voltage for the power supply of the device. When the Vout voltage exceeds the rated value of the voltage regulator tube D2, the frequency or duty cycle of the oscillation signal is interfered by the voltage regulator diode D2, the sixth resistor R2, the second transistor Q2 and the eighth resistor R5, so that the oscillation signal and the Vout voltage find a balanced and stable voltage point and stabilize, so that the power supply voltage Vout is maintained at a stable voltage value, for example, maintained at a voltage value of (3.0±0.2)V, thereby optimizing the low voltage battery voltage (for example, 1.2V) to the voltage value (for example, 3.0V) required for the stable operation of the dry battery using equipment.
[0033] In summary, through the circuit 10 for optimizing the use of battery power of the utility model, the dry cell battery-using device can work stably even when the battery voltage is low, thereby optimizing the device usage experience; at the same time, it can also make full use of the low power of the dry cell battery and extend the battery life.
