Abstract

The invention discloses a charging heat dissipation circuit and method, a wearable device and a computer readable storage medium; the charging heat dissipation circuit comprises a charging seat side circuit, an MOS transistor and a control module, the control module comprises a control end, the control end is connected with the MOS transistor and a charging interface, and the control end is used for controlling the conduction state of the MOS transistor. The charging and heat dissipation method comprises the steps that in the charging process of the wearable device, whether a CPU receives an input instruction of the wearable device or not is determined; if the CPU receives the input instruction, the potential of the grid electrode of the MOS tube is adjusted through the CPU; and if the potential is a low potential, the PMI is controlled to be charged through a VBUS of the charging interface, the PMOS transistor is switched on, the NMOS transistor is switched off, and the fan system enters an operation state. The technical problem that the heat dissipation effect is poor when the wearable device is charged is solved.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a charging and cooling circuit, a method, a wearable device, and a computer-readable storage medium. Background technique [0002] In recent years, the development of wearable devices has been favored by more and more users, and the demand is also increasing, and there is a trend of large screens. At present, the charging method for wearable devices usually uses the charging base to charge, that is, the metal contacts of the wearable device are placed on the charging base for charging, but charging in this way can easily cause obvious heating of the charging base and wearable devices. Phenomenon, especially when the user charges the wearable device while using the wearable device, the heating phenomenon will be more obvious. In response to this technical problem, the current intelligent heat dissipation system dissipates heat by attaching heat-dissipating graph...
