Prompt circuit and cup utilizing the same

摘要

A prompt circuit in a drinking cup includes a processor, temperature sensing and weight sensing units, and a prompt unit. The temperature sensing unit displays to a user the temperature of the liquid. The weight sensing unit detects a weight of liquid in the cup, and transmits the weight to the processor. The prompt unit includes a communication unit and a speaker unit. When any change of the weight of liquid in the cup within a first preset time is less than a preset value, the processor outputs a first control signal, to control the speaker unit to output an alarm. When the weight of liquid in the cup in unchanged for a preset time period after the speaker unit has output the alarm, the processor outputs a second control signal to the communication unit and the communication unit outputs a reminding message to a user.

主权项

1. A prompt circuit comprising:
a weight sensing unit configured to detect a weight change of liquid in a cup; a processor coupled to the weight sensing unit, configured to receive the weight change; and a prompt unit coupled to the processor, and comprising a communication unit and a speaker unit; wherein when the weight sensing unit detects the weight change is less than a preset value, the processor sends a first control signal to the prompt unit to control the speaker unit to output an alarm signal; and when the weight sensing unit detects the weight of liquid in the cup in unchanged for a preset time period after the output of the alarm, the processor outputs a second control signal to the prompt unit to control the communication unit to output a reminding message.
