Earphone charging box, charging control method and charging equipment

Abstract

The embodiment of the invention provides an earphone charging box, a charging control method and charging equipment. The earphone charging box comprises a charging box upper shell, a charging box lower shell, a charging bin, a main control circuit board and a charging box rechargeable battery, wherein the charging bin, the main control circuit board and the charging box rechargeable battery are located in an inner cavity of the charging box lower shell. The main control circuit board is fixed on one side of the outer surface of earphone storage cavities; a heating coil is fixed between the earphone storage cavities; the main control circuit board is electrically connected with a temperature detector and a control switch, the control switch is electrically connected with the heating coil, and the temperature detector is used for detecting an environment temperature or / and a battery temperature of the charging box; and a control unit MCU judges and controls the connection or disconnection of the heating coil and the control switch according to the comparison condition of the detected environment temperature or / and the battery temperature of the charging box and the preset optimal temperature. According to the invention, the optimal charging temperature is ensured to be provided for the charging box so that the charging current of the earphone charging box can be in a large enough state to charge an earphone, and a charging speed is greatly increased.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to an earphone charging box, a charging control method and a charging device. Background technique [0002] In recent years, portable and wearable electronic devices have been used more and more in people's lives; people's requirements for the charging speed of portable wearable devices are also getting faster and faster, and the charging speed is proportional to the size of the charging current. Wearable devices with a faster charging speed must require a large enough charging current. However, limited by the charging temperature requirements of the battery and the influence of the internal and external ambient temperature of the charging device, such as a cold place or a relatively low external ambient temperature, in actual use of the existing charging device, the speed of the charging current at different ambient temperatures It is also different, especially when the temperatu...

However, limited by the charging temperature requirements of the battery and the influence of the internal and external ambient temperature of the charging device, such as a cold place or a relatively low external ambient temperature, in actual use of the existing charging device, the speed of the charging current at different ambient temperatures It is also different, especially in the case of low temperature, the charging current speed will have a greater impact, so it is difficult to ensure that the charging current is always large enough and the charging speed is fast enough in the daily use of the existing charging box
