    摘要: An oral care implement including an elongated body having a head portion supporting plurality of tooth cleaning elements and a handle portion defining an outer surface. A grip control component is disposed on the handle portion and includes a pair of transversely spaced apart control surfaces separated by a longitudinally extending channel. The control surfaces are elevated above the outer surface of the handle portion and positioned to engage a user's thumb. The control component is operable to tilt the head portion at an upward or downward angle relative to a vertical plane of a user's teeth when the control component is grasped between the user's thumb and forefinger for producing a proper brushing angle at the gum line.

    摘要: An oral fluid delivery device includes a housing forming at least one cavity. The cavity includes at least two reservoirs, a first reservoir and a second reservoir. The device also includes an elongated neck with a distal end having at least one distal opening for passage of a fluid, a proximal end, and a channel fluidly connected to the distal opening. The device also includes a cap at the proximal end of the elongated neck. The cap includes at least one aperture aligned with the channel of the elongated neck and is rotatably coupled to the housing such that rotating the cap relative to the housing selectively aligns the aperture with a first reservoir opening to provide fluid communication between the first reservoir and the channel, or aligns the aperture with a second reservoir opening to provide fluid communication between the second reservoir and the channel.

    摘要: Provided are a brush head assembly and an electric toothbrush. The brush head assembly comprises a brush head body, a linking component and a locking cylinder; wherein a component assembly cavity is arranged at the tail end of the brush head body, the linking component is installed in the component assembly cavity, and a deformable locking cylinder including a fulcrum force-receiving part and a force applying part with elastic forces at both ends is embedded; the locking cylinder makes most of the strokes of the drive shaft in the insertion process smooth and convenient, only until the two force applying parts are both in contact with the drive shaft, will force be generated to lock the drive shaft, and the locking effect achieved by this elastic force can be maintained for a long time. Thus ensuring the capabilities of torque transmission and axial retention.
