[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Embodiment 1, as Figure 1 shown, this embodiment discloses an intelligent toothbrush, which includes a matrix cavity adapted to the shape of the tooth bed. A positioning groove 8 for installing a transmission mechanism is provided in the matrix cavity. The transmission mechanism can drive a slide bar to slide inside and outside and / or up and down along the matrix cavity. Brush pieces are respectively installed at both ends of the slide bar, and bristles are installed on the brush pieces.

[0024] Specifically, as Figure 2-3 shown, the matrix cavity is composed of an upper matrix 1 and a lower matrix 2 adapted to the shape of the tooth bed. As Figure 4 shown, the transmission mechanism 3 is composed of several connecting rods with protrusions 31. Adjacent connecting rods are connected by universal joints 32. Bite surface cleaning guide grooves 4 are opened at the top and bottom of the matrix cavity opposite to the connecting rods. An inside-and-outside movement slide bar 5 is installed in the bite surface cleaning guide grooves. As Figure 5 shown, brush pieces 51 are respectively installed at the upper and lower ends of the inside-and-outside movement slide bar. Bristles 52 facing the tooth bite surface are installed on the brush pieces. In addition, vertical strip-shaped holes 53 are opened on the inside-and-outside movement slide bar, and the protrusions of the connecting rods pass through the strip-shaped holes. The bite surface cleaning guide grooves are opened at the top and bottom of the matrix cavity opposite to the tooth bite surface. Inside-and-outside side cleaning guide grooves 6 are opened on both sides of the matrix cavity opposite to each connecting rod. An up-and-down movement slide bar 7 is installed in the inside-and-outside side cleaning guide grooves. As Figure 6 shown, brush pieces 71 are respectively installed at the left and right ends of the up-and-down movement slide bar. Bristles 72 facing the inner and outer sides of the teeth are respectively installed on the brush pieces. Horizontal strip-shaped holes 73 are opened on the up-and-down movement slide bar, and the protrusions of the connecting rods pass through the strip-shaped holes. The brush pieces at the left and right ends of the up-and-down movement slide bar are respectively adapted to the shape of the tooth bed. Concave structures are provided at the relative positions of the inside-and-outside movement slide bar and the up-and-down movement slide bar.

[0025] This embodiment also discloses a toothbrushing method. Using the above intelligent toothbrush, after putting the intelligent toothbrush into the mouth, drive the transmission mechanism to move around its axis. During the movement of the connecting rod of the transmission mechanism, its protrusion can drive the inner and outer moving slide rods to perform reciprocating inner and outer movements and drive the up and down moving slide rods to perform reciprocating up and down movements. During the reciprocating inner and outer movement of the inner and outer moving slide rods, the bristles at its upper and lower ends can clean the occlusal surfaces of the teeth. During the reciprocating up and down movement of the up and down moving slide rods, the bristles at its left and right ends can clean the inner and outer sides of the teeth. After the cleaning is completed, stop driving the transmission mechanism to move and take the intelligent toothbrush out of the mouth.
