  • Patent number: 11253052
    Abstract: An electrical toothbrush head includes a toothbrush body and an insertion piece that includes a core channel and a sideway slot in which an elastic bar is arranged. The core channel has a contact engagement surface. The elastic bar has a curved section. When the vibration core is inserted into the core channel, the contact engagement surface and the curved section respectively contact and engage with core side surfaces of the vibration core, and the elastic bar is pushed to elastically deform away from the contact engagement surface. When the electrical toothbrush head and the toothbrush handle are combined, the vibration core is clamped between the contact engagement surface and the curved section and the elastic bar deforms outward and the elastic filler block is compressed, such that the elastic filler block and the elastic bar cause the curved section to be in elastic engagement with the vibration core.

  • Patent number: 11234802
    Abstract: A toothbrush includes a head with a new design and a handle that operates to move the head. The toothbrush head has multiple types of purpose-designed bristle-bundles precisely mapped to target specifically all dental-gingival surfaces and anatomically niches, including various dead-corner niches/surfaces that are usually not accessible by currently existing toothbrushes. Each cluster of bristle-bundles contains bristles of different sizes, diameters, hardness, lengths, angulations and colors. The head is designed to be inclined to accommodate both lingual and palatal surfaces. This toothbrush head also functions uniquely by coupling over dental arches and rotating so that the brush does not need to be lifted during movement from one end to the other. Further, moving the handle with respect to the brush head causes the width of the brush head to change to accommodate the different widths of the teeth along the dental arch.

  • Patent number: 11234803
    Abstract: The invention relates an electrical cleaning and care appliance, pressure alarming method and apparatus for the appliance. Transducer elastic members of the appliance engage in resonance oscillation motion with bending strain characteristics, are symmetrically distributed on the left and right sides of the longitudinal axis (L2) of a drive shaft, and have approximately equal section moduli in bending, approximately equal lengths, approximately equal deflection amplitudes and opposite flexure directions; the angle between the longitudinal axis (L1) of a cleaning element and the normal direction of the transducer elastic member plane is 0° to 60°; the frequency of the alternating current in a drive coil is a fixed value equal to f0max?n, where n is a fixed value in the range of ?0.3(f0max?f0min) to 0.85(f0max?f0min). Therefore, the appliance has a higher mechanical efficiency, a simple structure and a lower cost.
