• the control method comprises the following steps:
• receiving a milk beverage preparation signal;
• when determining that a beverage mode corresponding to the milk beverage preparation signal is a beverage mode indicating steam output, controlling a pressure relief pipeline of the steam generator to open for a first preset duration, and controlling the steam generator to heat up during the first preset duration;
• after the first preset duration, controlling the hydraulic pump to activate for delivering milk liquid from the milk supply source to the mixing chamber, and controlling the steam generator to deliver the steam to the mixing chamber, wherein the steam enters the mixing chamber not later than the milk liquid.
