Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiment 1, as shown in fig. 1-2, this embodiment discloses a U-shaped toothbrush, which comprises a handle 9 and a U-shaped fixing seat mounted on the handle, wherein a motor is mounted in the handle, a brush head is uniformly arranged in the U-shaped fixing seat, the brush head is fixedly mounted on the U-shaped fixing seat through a shaft, and bristles are respectively mounted on two opposite side surfaces of the brush head, and a driving shaft 8 of the motor can drive the brush head to swing around the shaft in the U-shaped seat.

As shown in fig. 3, a baffle is arranged on the handle, and the U-shaped fixed seat is arranged on the baffle. The baffle 7 can be adjusted in axial position and is positioned in the mouth or attached to the outer wall of the mouth during tooth brushing, so that liquid splashing is prevented.

The U-shaped fixing seat is composed of a U-shaped inner fixing seat 1 and a U-shaped outer fixing seat 3, and as shown in fig. 8, the U-shaped outer fixing seat is fixedly arranged on the baffle through a positioning feature. The locating features include, but are not limited to, upper and lower circular holes. Can prevent the U-shaped fixed seat and the parts in the oral cavity from rotating relatively when brushing teeth. As shown in fig. 9, a incisor distance control block 6 is further installed on the U-shaped inner fixing base or the U-shaped outer fixing base. So as to control the distance between the upper and lower incisors and make the U-shaped toothbrush fit with the teeth. The incisor distance control block does not move with the brush head and is fixed during the whole brushing process.

In the embodiment, the brush head is fixedly arranged on the U-shaped fixed seat through a shaft and can swing around the shaft. When the brush head needs to be replaced, the brush head only needs to be taken down from the shaft, and the brush head is very convenient.

Types of brush heads include, but are not limited to, brush head C5 in the incisor region, brush head B4 in the canine region, and brush head A2 in the molar region.

As shown in figure 4, the brush head C is provided with a special-shaped hole, a special-shaped driving shaft of the motor can be inserted into the special-shaped hole of the brush head C, and two sides of the brush head C are respectively connected with other brush heads and can drive the other brush heads to swing around the shafts of the other brush heads. In the embodiment, two sides of the brush head C are respectively connected with other brush heads through connecting pieces.

As shown in figure 5, the brush head B of this embodiment uses single-sided bristles because the outer and inner teeth have different sizes or numbers of bristles due to different areas of the outer and inner sides. In addition, the brush head B can also adopt a brush with a small inner area and a large outer area.

As shown in fig. 6 and 7, since the occlusal surfaces of the molar parts also need to be cleaned, flat connecting parts are provided at positions where the brush head a faces the occlusal surfaces of the upper and lower molars, and bristles are provided on both sides of the connecting parts. When the brush head component swings left and right around the shaft, the bristles of the middle flat part also swing back and forth along with the shaft, and the occlusal surface is cleaned.

The motor is internally decelerated and mechanically adjusted, and the output angle and the rotating speed of a driving shaft of the motor can be adjusted to rotate.

As shown in fig. 10 and 11, after the teeth are occluded with the U-shaped fixed seats, the brush heads A, B, C are respectively opposite to the corresponding teeth, and the drive shaft of the motor drives the brush head C to swing left and right around the shaft of the brush head C, so that the incisor parts are cleaned. The brush head C drives the brush head B and the brush head A on the two sides to synchronously swing left and right around the shaft, thereby realizing automatic tooth brushing and comprehensive tooth cleaning.
