The present invention be the technical scheme is that a kind of core free motor to solve its technical problem, including fixture, ferrum Core, coil, tumbler and Magnet, what described tumbler can relatively rotate is installed on fixture, fixture and tumbler Corresponding the first through hole being formed with hollow out and the second through hole at center of rotation, iron core is fixedly installed in fixture or rotation On the side wall of part, coil is wound on iron core periphery surface, ferromagnetic corresponding is fixedly installed in outside tumbler or fixture On wall, and Magnet is corresponding with coil position and relatively rotates.

As the improvement further of invention, described fixture one end end face is formed with least one circle toroidal cavity knot Structure, tumbler side wall is provided with least one circle and toroidal cavity structure corresponding annular concave wall on fixture, described The one-to-one corresponding that annular concave wall on tumbler can rotate is inserted in the circular groove structure of fixture.

As the improvement further of invention, described some iron cores are fixedly installed in fixture circle along what fixture radially extended On all lateral walls, Magnet is fixedly installed in tumbler one side surface, and Magnet is just coated on coil away from fixture axis direction Side.

As the improvement further of invention, described tumbler periphery wall forms the bending edges towards side, and Magnet is solid Dingan County is loaded on this bending edges inner surface.

As the improvement further of invention, the bending edges on described tumbler are just coated and fixed part and iron core thereon completely And coil.

As the improvement further of invention, described iron core is provided with the one end away from fixture periphery wall rotating The bulge-structure in part direction, this bulge-structure is provided with the annular groove concentric with toroidal cavity structure on fixture, rotates One circle is just provided with the wall of part side and can correspond to the annular concave wall that rotation is inserted in this annular groove.

As the improvement further of invention, described first and second runs through in the hole is provided with installation hard-wired for functional part Structure.

As the improvement further of invention, described functional part is in anion generator, quintessence oil, aerosol apparatus and medicated bag One or more of combination.

The method have the benefit that: the present invention is connected by the center of rotation formation in tumbler and fixture First and second through hole, first and second through hole forms air channel, and the heat occurring in tumbler high-speed rotation can be quick Taken away by air channel, rapid heat dissipation, tumbler also have concurrently shell effect, be more beneficial for radiating simultaneously simplify structure, reduce entirety Volume and quality, tumbler and fixture are rotatably assorted connection by multiple bulge loops and toroidal cavity structure, connective stability Height, is difficult to shake little, suitable environment is wide during use.

Brief description

Fig. 1 is the principle schematic diagram. of the present invention.

Specific embodiment

Embodiment: a kind of core free motor, including fixture 1, iron core 2, coil 3, tumbler 4 and Magnet 5, described tumbler 4 can relatively rotate be installed on fixture 1, the corresponding hollow out that is formed with the center of rotation of fixture 1 and tumbler 4 First through hole 6 and the second through hole 7, iron core 2 is fixedly installed on fixture 1 or the side wall of tumbler 4, and coil 3 is wound in On iron core 2 periphery surface, ferromagnetic corresponding be fixedly installed on tumbler 4 or fixture 1 outer wall, and Magnet 5 and coil 3 Position is corresponding and relatively rotates, after galvanization on the coil 3 under the action of a magnetic field tumbler 4 around fixture 1 high-speed rotation, by It is centrally formed corresponding first and second through hole in tumbler 4 and fixture 1, be the formation of air channel here, can be by tumbler 4 Generate heat during rotating against with fixture 1 and quickly take away, heat-sinking capability strong it is ensured that motor is capable of the work of long-time stable, First and second through hole at center may further be used to wear control circuit, increases axial flow simultaneously.

At least one circle toroidal cavity 12 structure 8 is formed with described fixture 1 one end end face, on tumbler 4 side wall It is provided with least one circle and the corresponding annular concave wall 9 of 12 structure of toroidal cavity on fixture 18, the circle on described tumbler 4 The one-to-one corresponding that annular protrusion wall 9 can rotate is inserted in the circular groove structure of fixture 1, by arc-shaped convex Wall rotates in toroidal cavity 12 structure 8 realizes rotational positioning, and multiple arc-shaped convex walls are tied with multiple toroidal cavities 12 Structure 8 coordinates, stable connection, and rotational stabilization is high, and vibrations are little, and life-time service is hardly damaged.
