Detailed Description

The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:

referring to fig. 1-4, the invention comprises a rotor body 7, a heating coil 5, an inductance coil 3, permanent magnets 10 and 11, a magnetic steel 6 and a guide member 8, wherein the rotor body 7 is arranged in a cylinder body 2, the cylinder body 2 is made of ceramic material, the heating coil 5 is arranged on a container base 4, a wire control circuit board 9 sequentially energizes the inductance coil 3 wound on the base, the magnetic steel 6 acts on the rotor body 7 and the inductance coil 3 to enable the rotor body 7 to rotate in a suspended manner, the permanent magnets 10 and 11 are respectively arranged on the rotor body and the guide fixing member 8 to enable the rotor body 7 to be always centered, the product integrates stirring and heating functions on bodies, and the heating coil 5 is separated from the cylinder body 2, so that the cylinder body 2 does not need to be directly energized in the whole heating process, thereby being safe, reliable and convenient to use, and the rotor assembly has no fixed shaft, thereby.

The rotor assembly has magnetic steel 6 and permanent magnet 10 mounted on rotor body 7 for shaftless rotation.

The heating coil 5 is arranged on the base 4, the bottom of the cylinder body 2 is heated after the heating coil is electrified, so that the heating purpose is achieved, and the safety of is ensured when the electrifying device is separated from the heating device.

8 coils 3 wound on the base are sequentially electrified by the wire control circuit board, so that the rotor assembly is suspended and rotated to achieve the purpose of stirring.

The guiding fixing piece 8 ensures that the rotor assembly is always at the position of the central line of the cylinder body 2 and is not contacted with the wall surface of the cylinder body 2, thereby reducing the collision between the rotor body 6 and the inside of the cylinder body 2, leading the shaftless homogenizer to have more use reliability.

The number of magnetic pole pairs of the coil wound on the base is 4, the wire control circuit board sequentially energizes the corresponding number of magnetic pole pairs during working, and a magnetic field generated in the coil and magnetic steel on the rotor assembly act to achieve the purpose of rotary suspension of the rotor assembly.
