Patent ID: 11096768

Abstract:
A brush head includes a connecting member detachably mounted in a brush head body, and an elastic element mounted on an outer surface of the connecting member and including a connecting portion with a slot and two clamping portions. A through opening is formed in the connecting member and the middle of each clamping portion is bent inwardly to form an abutting arch capable of deforming elastically in a radial direction of the slot. When the abutting arches are not stressed, the distance between vertex ends of the abutting arches is smaller than a radial thickness of the driving shaft of the electric toothbrush. After the driving shaft is inserted into the slot, the two abutting arches penetrating through the through openings is deformed and directly abut against the driving shaft so that the brush head and the driving shaft are connected stably. The brush head is simple in structure.
