The invention provides a smart drinking cup comprising a smart control circuit, a cup body and a sensing touch switch arranged at the edge of the cup mouth. The smart control circuit comprises a weighing module, a clock module, a storing module, a bluetooth module, a control module, a voice module and a power module. The control module is connected with the sensing touch switch, the weighing module, the clock module, the storing module, the bluetooth module, the control module, the voice module and the power module to receive signals from the weighing module, the clock module, the bluetooth module and the sensing touch switch to process signals and send control signals to the storing module, the voice module and the sensing touch switch according to the processing results; after the control module detects the sensing touch switch to generate sensing signals, the control module sends control signals to the storing module to store data. The smart drinking cup can accurately record drinking action and drinking amount each time, and is equipped with timely drinking reminding function, daily drinking amount calculation, drinking amount inefficiency reminding function and the like so as to provide supervision and management to personal drinking.
