摘要： A toothbrush head for an electric toothbrush, comprising a toothbrush head handle (1); a first plate (4) is arranged below the toothbrush head handle (1); and a first bristle sheet (9) and a second bristle sheet (8) are longitudinally arranged below the first plate (4). Tooth cleaning demands of people different in oral cavity and tooth size can be satisfied by means of surrounding effects of the three-sided bristles and self-adaptive effects of automatic bristle fitting along with thickness changes from front teeth to molars.

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.

In the exemplified embodiment, the cleaning elements have a plurality of bristle tufts each including a plurality of bristle filaments. In one aspect, the oral care implement may include a first bristle tuft having inner and outer filaments with the outer filaments being taller than the inner filaments and a second bristle tuft having inner and outer filaments with the outer filaments being shorter than the inner filaments. The first bristle tufts may be arranged on the head in a position so as to surround the second bristle tufts, or the second bristle tufts may be arranged on the head in a position so as to surround the first bristle tufts. Distal ends of the first and second bristle tufts may be angled.

摘要： A toothbrush for brushing action by providing a lateral motion within a plane in which a dentition exists. The toothbrush 200 has a brush member 210, a guide 221 for guiding a movement of the brush member 210, a guide connector 222 for connecting the guide 221 to a drive source and a brush frame 223 connected to the guide 221 for fixing the brush member 210. The guide 221 has a first region 221A and a second region 221B with a lower elastic modulus than the first region 221A. A force applied from the dentition to the brush member 210 fixed to the brush frame 223 is transmitted to the second region 221B by way of the first region 221A and the brush frame 223. This causes deformation of the second region 221B. The deformation fulfills the role of guiding the movement of the brush member 210.
