Toothbrush with independently adjusting bristle clusters

Abstract

A toothbrush of the invention uses magnetic repulsion phenomenon to effectively clean teeth surface. The head of the toothbrush accommodates plurality of bristle clusters, each cluster having a magnet affixed to its base. Another magnet is positioned underneath such base and aligned so that identical poles of both magnets face one another. Such alignment generates magnetic repulsion which, when combined with the brushing motion initiated by user, ensures that bristle clusters individually adjust to irregular teeth surface and reach deep into separation between adjoining teeth thus ensuring effective cleaning of the teeth and gaps between them.

What is claimed is: 
     
         1 . A toothbrush comprising a gripping handle and a brushing member attached to the distal end of said handle;
 said brushing member having plurality of bristle clusters implanted into its face with base of each of said bristle clusters positioned underneath said brushing member surface and placed within an individual encasement;   Said encasement holding said base of one bristle cluster and accommodating a lower magnet affixed to the bottom of said encasement and an upper magnet affixed to said base of said bristle cluster;   Wherein said magnets are in substantially parallel alignment positioned so that their identical magnetic poles face one another.   
     
     
         2 . A toothbrush of  claim 1  wherein said magnets are positioned so that south poles of said lower and upper magnets face one another. 
     
     
         3 . A toothbrush of  claim 1  wherein said magnets are positioned so that north poles of said lower and upper magnets face one another. 
     
     
         4 . A toothbrush of  claim 1  where said magnets are permanent magnets. 
     
     
         5 . A toothbrush comprising a gripping handle and a brushing member attached to the distal end of said handle;
 Said brushing member having plurality of bristle clusters implanted into its face with a base of each of said bristle clusters positioned underneath the surface of said brushing member and placed within an encasement;   Said encasement holding said bases of all bristle clusters, and accommodating a lower magnet affixed to the bottom of said encasement and a number of upper magnets equal to the number of said bristle clusters, one of each of said upper magnets affixed to one of said bases of bristle clusters;   Wherein said upper magnets are in substantially parallel alignment to said lower magnet and positioned so that their identical magnetic poles face the identical pole of said lower magnet.   
     
     
         6 . A toothbrush of  claim 5  wherein said magnets are aligned so that south pole of said lower magnet faces and south poles of said upper magnets. 
     
     
         7 . A toothbrush of  claim 5  wherein said magnets are aligned so that north pole of said lower magnet faces and north poles of said upper magnets. 
     
     
         8 . A toothbrush of  claim 5  where said upper and lower magnets are permanent magnets.
