Abstract

A liquid extraction control method includes: acquiring a current temperature value of liquid to be extracted; determining whether the current temperature value is within a predetermined temperature value range; opening a liquid flow channel when the current temperature value is within the predetermined temperature range, and closing the liquid flow channel when the current temperature value is outside the predetermined temperature range. The temperature range of the liquid to be extracted can therefore be controlled, reducing probability of injuries caused by overly hot or cold liquid through a straw, and facilitating control of the temperature and extraction amount suitable for users, so as to achieve smart and quantitative fluid extraction.
