There is provided an electric toothbrush including a toothbrush head, a toothbrush handle and a force sensing array. The force sensing array is arranged on the toothbrush head and/or the toothbrush handle. When the force sensing array is arranged on the toothbrush head, it is able to detect the force uniformity of brush hairs. When the force sensing array is arranged on the toothbrush handle, it is able to control the vibration strength of the brush hairs and detect the pressing force of the brush hairs.

Provided are a motor for an electric toothbrush and an electric toothbrush having the same. The motor includes a housing and at least one pair of rotor iron core groups fixed within the housing, wherein each rotor iron core group is formed by stacking a plurality of rotor iron cores, each of the plurality of rotor iron cores includes an iron core main body portion and an iron core convex portion protruding outwards from the periphery of the iron core main body portion; and at least one pair of rotor iron core groups are inserted into two axially extending iron core brackets, and the two iron core brackets are each provided with a clamping groove, with the clamping grooves having openings opposite to each other.

The present invention relate to an electric toothbrush with an elongate body comprising a housing, a brush head and a neck member arranged between the housing and the brush head, wherein i) the housing accommodates a motor for generating an oscillation movement to a shaft extended from the motor, i) the neck member couples with the shaft such that the oscillation movement is transmittable to the neck member whereby the neck member and the shaft are oscillatable together in the same extent, iii) a proximal end of the brush head is provided with a circumferential region rotatably fitted to a distal end of the neck member, and iv) the electric toothbrush further comprises an elongate strip member extending from the neck region to the brush head with opposite ends of the strip member fixedly connected to the brush head and the neck member, respectively.

A teeth cleaning system, which provides improved coverage or brushing area. The system includes an actuated tray comprises brushing elements. The brushing elements may be positioned to engage the front, rear, and top surfaces of the upper and lower jaw teeth. The actuation may be configured to oscillate the tray in a lateral direction which may brush all the surfaces of teeth simultaneously. Some embodiments include a higher density of bristles which increases the effectiveness of brushing. In addition, aspects of the system reduce the time spent brushing teeth.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

A method for producing a mouthpiece toothbrush is provided, in which at least one dental arch of the patient for whom the toothbrush is intended is scanned to generate scan data, or an impression of the dental arch is made. Based on the scan data or the then digitised impression, the dental arch space occupied by the dental arch is recorded. A bristle space is constructed around the at least one dental arch, and a toothbrush moulded piece is calculated, the surface of which facing the dental arch is determined by the dental arch space plus the bristle space. The surface is covered with a bristle carpet.

A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

A control method and control system for a smart toothbrush. An App terminal reads the tooth brushing scheme of the cloud. The App terminal recommends a matched tooth brushing scheme according to personal information of a user. Finally, based on the user's selection, the recommended tooth brushing scheme is pushed to the smart toothbrush for parameter adjustment. Alternatively, a customized or re-selected tooth brushing scheme is pushed to the smart toothbrush for parameter adjustment. The control method and control system for the smart toothbrush meet many tooth brushing needs for different people, improving the applicability of the smart toothbrushes.

An eccentric vibration structure of electrical toothbrush includes an eccentric rod. Two ends of the eccentric rod are respectively formed with a transmission section and a weight section. The transmission section is drivable by a driving force to rotate so as to drive the weight section to eccentrically vibrate. The weight section has at least one weight part for partially or totally increasing the weight of the weight section, whereby due to the increased weight, the weight section is unbalanced in weight to deflect from a central axis of the eccentric rod.

The present invention relates to a fingertip toothbrush for a pet, and more particularly, to a fingertip toothbrush for a pet that is configured to allow bristles to vibrate and reciprocally slide up and down, so that toothbrushing can be carefully and precisely achieved, which is effective in improving the teeth health of the pet.
