Wherein, the surface of seal from the housing extends to transmission connection piece;Transmission connection piece is additionally provided with set towards the end face of rotating shaft
The seal sleeve joint hole of seal is connect, the one end of seal is stretched into seal sleeve joint hole, the outer surface of seal and sealing
The formation rotary seal connection of part sleeve joint hole；Tooth powder when brushing teeth must be first right by seal and ability after the abrasion of seal sleeve joint hole
Seal produces effect of attrition with rotating shaft, and this just considerably increases sealed reliability and the working life of toothbrush.
In above-mentioned technical proposal, it is further preferred that being additionally provided with twisted rotary shaft between the seal and rotating shaft and housing
The first cavity, be filled with Seal Oil in the first cavity so that the sealing effectiveness of seal more preferably, while Seal Oil can also subtract
Pivoting friction between small rotating shaft and seal.
In above-mentioned technical proposal, it is further preferred that being socketed on the end face and seal of seal in seal sleeve joint hole
Keep the end face in interval, seal outer surface to enclose the second cavity with seal sleeve joint hole between the bottom surface of sleeve joint hole, make
The tooth powder that the second cavity must be entered through seal can not be in a short time to causing abrasion seal and rotating shaft.
In above-mentioned technical proposal, it is further preferred that the second cavity in be filled with Seal Oil, further increase sealing and
Wear-resistant effect, while reducing the pivoting friction between transmission connection piece and seal.
Compared with prior art, the present invention from the housing of motor by seal by extending to transmission connection piece, and is passing
The end face of follower link sets seal sleeve joint hole, adds the seal length and sealing area of seal so that motor is obtained
Preferably protection, improves the job security and working life of electric toothbrush；By setting the first cavity and the in seal
Two cavitys, and fill in cavity Seal Oil, it is ensured that the sealing effectiveness of seal, while reducing seal and rotating shaft, passing
Friction between follower link.
