Referring to fig. 3, 4 and 9, the front end surface of the base is provided with 3 connecting pieces for limiting the range of motion of the brush body; the base body comprises a base part 21 and a cover part 22 fixedly connected to the front end of the base part, and the connecting piece is integrally connected to the front end of the cover part.
The connecting piece is including the support column 21 of integral connection at the pedestal front end to and fixed connection be in the spacing part 27 of support column front end, the brush body is injectd between support column front end and spacing part, and the brush body rotates with support column or spacing part to be connected.
Specifically, the front end of the supporting column is provided with an inserting column 222 with a polygonal column structure, and the rear end of the limiting component 27 is provided with a fixed connecting part 272 fixedly sleeved with the inserting column. Of course, the positions of the insertion column and the fixed sleeve part can be reversed.
The front end of the limiting component is a stop-off limiting part 271, a connecting through hole 232 is formed in the middle of the brush body, a limiting inner convex ring 233 is arranged on the inner wall of the connecting through hole, and the limiting inner convex ring is located below the stop-off limiting part.
The thickness of the limiting inner convex ring is smaller than the length of the part, below the anti-falling limiting part, of the limiting part, so that the brush body can axially move along the supporting column.
A gap is formed between the inner wall of the limiting inner convex ring 233 and the outer wall of the limiting part below the anti-falling limiting part, so that the brush body can axially and relatively deflect relative to the supporting column. The deflection means that the brush body front end is subjected to a pressure when it comes into contact with the skin, so that the brush body front end is brought into or tends to coincide with the skin, i.e. the axial direction of the brush body is offset from the axial direction of the support column. That is, the brush body can rotate in any direction in a three-dimensional space within the range defined by the connecting piece.
The brush body is provided with a driven magnet 230, and the base body is rotatably provided with a driving magnet 250 which is connected with the driven magnet through magnetic transmission; the driven magnet and the driving magnet respectively comprise 3-5 magnets distributed in a circumferential array, and the magnetic field directions of the driven magnet and the driving magnet are arranged in opposite directions.
The front end of the brush body can move towards the direction of the base body under the action of external pressure and reset towards the direction far away from the base body under the action of the magnetic field force of the driven magnet and the driving magnet.
And a transmission part in transmission connection with the driving magnet and a rotating motor in the host is arranged in the seat body.
The position that corresponds each connecting piece in the seat rotates installs driven gear 25, the driving magnet is installed on the driven gear who corresponds the position, still rotate in the seat and install the drive gear 26 of being connected with each driven gear meshing transmission, drive gear coaxial coupling has the drive shaft 260 of being connected with the rotating electrical machines transmission in the host computer, drive gear, drive shaft, each driven gear constitute jointly transmission component.
The driven gear is formed with a driving magnet mounting groove 251 for receiving and fixing a driving magnet, and the brush holder is formed at a rear end or inside thereof with a magnet mounting groove 234 for receiving and fixing a driven magnet.
In this embodiment, the driven magnets and the driving magnets are driven by magnetic field force, and the brush body floats relative to the base body by magnetic field repulsion force (that is, the front end of the brush body can move towards the base body under the action of external pressure, and can reset towards the direction away from the base body under the action of the magnetic field force of the driven magnets and the driving magnets), so that the driven magnets and the driving magnets distributed in a circumferential array are arranged in a staggered manner, that is, in the driven magnets or the driving magnets, the distance between two adjacent magnets is greater than the outer diameter of one magnet, so that when the driven gear rotates, the driving magnets can push the driven magnets (together with the brush body) to rotate relative to the supporting column by the magnetic field repulsion force, and meanwhile, the magnetic field repulsion force can enable the brush body to be in a floating.
Furthermore, in this embodiment, the driving magnet and the driven magnet used in pair realize the transmission and floating of the brush body through the magnetic field repulsion force, and when the front end of the brush body is not subjected to an external force, the limiting inner convex ring on the brush body is abutted against the anti-disengagement limiting part, so that the whole front end of the brush body is kept parallel to the base body, namely, the initial state of the brush body. If the initial state of the brush body needs to be changed, a permanent magnet or a magnetic conductive iron block which interacts with the driven magnet through magnetic field force can be additionally arranged in the seat body. For example, the permanent magnet or the magnetic iron block is additionally arranged at the center of the seat body, so that the brush body can incline towards the center of the front end of the seat body in the initial state. After the front end of the brush body can move or rotate or deflect under the action of external pressure, the driving magnet can drive the brush body to return to the initial state through the magnetic field repulsive force with the driven magnet.
When the brush head assembly is used, the front end of the brush head assembly is slightly pressed on the skin, and the rotating motor in the main machine drives the brush body to rotate, so that the skin can be cleaned or massaged. When the front end of each brush body is pressed, the posture of each brush body can be self-adaptively adjusted according to the shape of the skin at the current cleaning position, so that as many bristles as possible are in contact with the surface of the skin, and the cleaning efficiency is improved.
For example, when the brush head assembly contacts with the skin on the surface of the convex joint part, at least part of the brush bodies deflect towards the center of the front end of the base part, and the front ends of the brush bodies enclose a shape similar to a conical concave surface. When the brush head component is contacted with the skin of the concave part, the part of the brush body close to the outer end of the base part is firstly contacted with the skin, and the front end of each brush body forms a shape similar to a forward convex conical surface by slightly applying pressure to the front direction of the brush head component, so that the part of the brush body close to the middle of the seat body can also be contacted with the body surface.
In the front-rear direction, the brush side is the front side, and the side of the base portion connected to the main unit is the rear side.
