Abstract:
The toothbrush in the present invention comprises a toothbrush handle and a toothbrush head. The toothbrush handle comprises a handle body and a head located on one end of the handle body. The toothbrush head comprises a head piece and a plurality of bristles disposed thereon. A fixing adhesive is provided between the head piece and the head so as to fix the toothbrush head at the head to improve the conventional ultrasonic welding approach or viscose approach to fix the toothbrush head instead of fixing the toothbrush head by means of a second injection of a soft fixing adhesive, which can improve the stability of combining the toothbrush head into the toothbrush handle.
