Abstract: A juicer comprises a base part, a juicer body, a strainer, a threaded cutter and a feed inlet, wherein the strainer is arranged within the juicer body, the juicer body is covered over with the feed inlet and a squeezing chamber is formed between the feed inlet and the strainer, and a buffer chamber is formed between the upper portion of the threaded cutter and the lower portion of the feed inlet; a pivot joint is arranged at the top of the screw body and is pivotally connected to the inner surface of the lower portion of the feed inlet, and the upper portion of the screw body from bottom to top is tapered at first and then broadened to form a radial projecting top. The juicer has increased squeezing efficiency and juice yield, and avoids accumulation of squeezed food.

Abstract: The present invention discloses a method for controlling a mixer, including sending a fan initiation control signal to the fan when obtaining a instruction for initiating the mix from the user, to allow the fan to operate at a pre-set fan rotation speed; sending a motor initiation control signal to the motor to allow the motor to operate at a pre-set motor rotation speed within a set mixing time period; wherein the instruction for initiating the mix includes the mixing time period; sending a motor stop control signal to the motor when the mixing time period is ended to stop the operation of the motor; and sending a fan stop control signal to the fan after a pre-set first delayed time period to stop the operation of the fan. Meanwhile the present invention also provides a controller for a mixer and a mixer.
