Sealing sleeve joint hole forms rotary seal and connects；Dentifrice when brushing teeth must be first by ability after sealing member and the abrasion of sealing member sleeve joint hole
Sealing member is produced effect of attrition, this reliability just considerably increasing sealing and the working life of toothbrush with rotating shaft.
In technique scheme, it is further preferred that be additionally provided with twisted rotary shaft between described sealing member and rotating shaft and housing
The first cavity, be filled with Seal Oil in the first cavity so that the sealing effectiveness of sealing member is more preferable, and Seal Oil can also subtract simultaneously
Pivoting friction between little rotating shaft and sealing member.
In technique scheme, it is further preferred that be socketed on end face and the sealing member of sealing member in sealing member sleeve joint hole
Keeping interval between the bottom surface of sleeve joint hole, the end face in seal outer surface and sealing member sleeve joint hole enclose the second cavity, make
Must enter the dentifrice of the second cavity through sealing member can not be at short notice to causing abrasion sealing member and rotating shaft.
In technique scheme, it is further preferred that be filled with Seal Oil in the second cavity, further increase sealing and
Wear-resistant effect, reduces the pivoting friction between transmission connection piece and sealing member simultaneously.
Compared with prior art, this utility model by sealing member is extended to transmission connection piece from the housing of motor, and
End face at transmission connection piece arranges sealing member sleeve joint hole, adds seal length and the sealing area of sealing member so that motor
Preferably protected, improve job security and the working life of electric toothbrush；By arranging the first cavity at sealing member
With the second cavity, and filling Seal Oil in cavity, it is ensured that the sealing effectiveness of sealing member, reduce sealing member simultaneously and turn
Friction between axle, transmission connection piece.
