When the voltage value for charging the battery 30 is preset to be 8.4V, when the power supply 10 is turned on, the second triode Q2 is turned on, and sends a signal to the micro control unit, so that the micro control unit controls the motor M1 in the motor control circuit 40 to stop working, and at the same time, the enable pin EN of the boost chip U1 in the charging boost circuit 50 receives a high level, and boosts the 5V voltage input by the power supply 10, and raises the 5V voltage input by the power supply 10 to the preset voltage value of 8.4V, and then outputs the preset voltage value to the battery 30.
In the embodiment of the application, by adding the charging booster circuit comprising the booster chip, when an enable pin in the booster chip receives a high level, if the voltage of the input power supply does not reach a preset voltage value, the voltage of the input power supply is boosted to be increased to the preset voltage value, and then the boosted voltage is output to the battery to charge the battery.
The embodiment of the application also provides an inflator pump, which comprises the charging booster circuit, and if the voltage of the power supply input by the inflator pump does not reach the preset voltage value, the voltage of the power supply input by the inflator pump is boosted, so that the voltage of the power supply input by the inflator pump is increased to the preset voltage value, and then the voltage is output to the battery to charge the battery. Since the charging speed is faster as the voltage input to the battery is higher, the efficiency of charging the battery can be improved.
