In technique scheme, it is further preferred that be additionally provided with the first cavity of twisted rotary shaft between described sealing member and rotating shaft and housing, in the first cavity, it is filled with Seal Oil, the sealing effectiveness making sealing member is more preferable, and Seal Oil can also reduce the pivoting friction between rotating shaft and sealing member simultaneously.
In technique scheme, further preferably, it is socketed between the end face of sealing member in sealing member sleeve joint hole and the bottom surface of sealing member sleeve joint hole holding interval, end face in seal outer surface and sealing member sleeve joint hole enclose the second cavity so that the dentifrice entering 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 and seal and wear-resistant effect, reduce the pivoting friction between transmission connection piece and sealing member simultaneously.
Compared with prior art; the present invention is by extending to transmission connection piece by sealing member from the housing of motor; and sealing member sleeve joint hole is set at the end face of transmission connection piece; add seal length and the sealing area of sealing member; motor is preferably protected, improves job security and the working life of electric toothbrush；By arranging the first cavity and the second cavity, and filling Seal Oil in cavity at sealing member, it is ensured that the sealing effectiveness of sealing member, reduce the friction between sealing member and rotating shaft, transmission connection piece simultaneously.
