The driving mechanism 30 is disposed on the base 10, the driving mechanism 30 includes a motor 31 and a transmission member 32 in driving fit with the motor 31, and the transmission member 32 can be abutted to the stirring structure 90. The controller is disposed on the base 10. The electromagnetic induction device 40 is disposed on the base 10, and the electromagnetic induction device 40 is connected to the controller. Wherein, be provided with iron material portion 321 on the driving medium 32, iron material portion 321 has the inductive position of cooperating with electromagnetic induction device 40 and the dodge position of not cooperating with electromagnetic induction device 40, and under the condition that iron material portion 321 is in the inductive position, electromagnetic induction device 40 sends predetermined container signal or motor control signal to the controller.

According to the technical scheme of the first application embodiment, the electromagnetic induction device 40 and the iron material portion 321 are arranged, and the electromagnetic induction device 40 is connected with the controller. The iron portion 321 is provided on the transmission member 32, and the iron portion 321 has a sensing position that engages with the electromagnetic induction device 40 and a retracted position that does not engage with the electromagnetic induction device. When the iron portion 321 is in the sensing position, the electromagnetic induction device 40 sends a predetermined container signal or a motor control signal to the controller. The controller can judge the type of the container after receiving the preset container signal, whether the stirring structure 90 is arranged, and then sends a signal to prompt a user according to the type of the container, so that the mixed use of the container is avoided.
