It can be understood that the base 2 includes a supporting plate 22 facing the bottom of the stirring cup 1, the coupler 21 is disposed through the upper and lower plate surfaces of the supporting plate 22, various sensors such as temperature and pressure are disposed on the stirring cup 1, and the electrical connection terminal is connected to the coupler 21 to ensure the normal power-on operation of the sensors, so that when the stirring cup 1 leaves the base 2, the coupler 21 exposed outside is not electrified, which is the most ideal and safe state. The control process is realized through the matching of the magnetic switch 4 and the magnetic piece 5, namely the magnetic switch 4 is used for controlling the on-off of the current of the coupler 21 according to the distance of the magnetic piece 5, and it is easy to understand that the magnetic piece 5 is close to the magnetic switch 4, the magnetic switch 4 detects that the surrounding magnetic field is strong, the coupler 21 is controlled to be electrified, the magnetic piece 5 is far from the magnetic switch 4, the magnetic switch 4 detects that the surrounding magnetic field is weak, and the coupler 21 is controlled to be powered off. In this embodiment, the distance is defined as: when the stirrer is positioned on the base 2, the magnetic part 5 is considered to be close to the magnetic switch 4; if the stirrer is not placed on the base 2, the magnetic part 5 is far away from the magnetic switch 4; therefore, the purpose that the coupler 21 is powered off immediately after the stirring cup 1 leaves the machine base 2 is achieved.

In this embodiment, the magnetic member 5 is a permanent magnet, and it can be understood that the permanent magnet has stable magnetism and long service life, and can effectively reduce the frequency of maintenance and replacement for a user, for example, but not limited to, the permanent magnet may be a permanent magnet or other permanent magnet metals.
