[0050] The magnetic drive plate 110 is used for generating a magnetic field by electrification;
[0051] The rotating assembly 120 is rotatably connected to the magnetic drive plate 110 at one end, and the rotating assembly 120 is coupled to the magnetic drive plate 110;

[0053] The stirrer 140 is coupled to the drive magnet 130;
[0054] The magnetic drive plate 110 generates a magnetic field to drive the rotating assembly 120 to rotate, to drive the drive magnet 130 to rotate, so that the drive magnet 130 drives the stirrer 140 to stir.
[0055] Please refer to Figures 1-5In the embodiment, the magnetic force driving plate 110 generates a magnetic field when electrified. Since the rotating assembly 120 is coupled with the magnetic force driving plate 110, the magnetic field of the magnetic force driving plate 110 drives the rotating assembly 120 to rotate, so that the driving magnet 130 rotates, and further drives the stirrer 140 to rotate, so that the stirrer 140 stirs the liquid, to achieve the stirring effect.
[0056] Since the magnetic force driving plate 110 generates a magnetic field when electrified, there is no need to increase the magnetic induction coil, thereby reducing the thickness of the driving structure, reducing the volume and thickness of the overall stirring structure, and further facilitating the use of the user.
[0057] It should be noted that the magnetic force driving plate 110 is a circuit board, which generates a magnetic field when electrified. By changing the direction and size of the current, the direction and strength of the magnetic field are adjusted to drive the rotating assembly 120 to rotate.
[0058] The stirrer 140 is a magnetic block, and the driving magnet 130 is a magnetic block.
[0059] Preferably, the rotating assembly 120 comprises:
[0060] The connecting shaft 121 is rotatably connected to one end of the magnetic force driving plate 110, and is fixedly connected to the other end of the driving magnet 130;

[0063] Please refer to Figures 1-5 In the embodiment, the magnetic force driving plate 110 generates a magnetic field acting on the transmission magnet 122. Under the action of the magnetic field of the magnetic force driving plate 110, the driving transmission magnet 122 rotates around the central axis of the connecting shaft 121. Since the transmission magnet 122 is installed on the connecting shaft 121, the transmission magnet 122 drives the connecting shaft 121 to rotate.
