It moves, the removal that friction promotes dental plaque, calculus and spot occurs between the grinding agent and dental surface in lotion.
The prior art has the disadvantage that
One, the extend internally structure of rib and symmetrical blading of traditional polishing rotor makes polishing rotor can effective cleaning tooth table
Face, but they cannot provide the cleaning to gum and the gum seam on tooth periphery.Gum is the gingiva tissue for surrounding tooth neck
A part, gum crack are that the base portion of gum eruption tooth is slightly less than a part of gum base surface.And effective tooth
Cleaning needs the plaque removed from the gum of dental surface, gum and tooth periphery seam, spot and microorganism；
Two, it is begun to before antiscuffing paste contact tooth of the rotation of polishing rotor usually in cup.When polishing rotor rotation,
Centrifugal force is perpendicular to rotation axis, and due to the design that wall of cup is inclined outwardly, so the component of the centrifugal force will be along polishing rotor
The inner surface of side wall is directed to outside polishing rotor, and the antiscuffing paste in cup is by centrifugal force pulls to cup external migration out of cup.It is existing
The line of the blade of structure, root and wall of cup with polishing rotor axis in the same plane, therefore antiscuffing paste cannot be inhibited
Migration.Cause antiscuffing paste to be often prematurely released from cup, wastes lotion；
