DETAILED DESCRIPTION

[0018] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings.

[0019] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A multi-surface toothbrush comprises a brush handle 1 and a brush head 2. The cross section of the handle of the brush handle 1 is a regular polygon. The brush head 2 comprises a first cleaning plate 21, a second cleaning plate 22 and a third cleaning plate 23. The two ends of the second cleaning plate 22 are respectively fixedly connected to the opposite sides of the first cleaning plate 21 and the third cleaning plate 23, so that the brush head 2 is an I-shaped structure. The opposite sides of the first cleaning plate 21 and the third cleaning plate 23 cooperate with the side wall of the second cleaning plate 22 to form a U-shaped cavity. The brush head 2 has two symmetrically arranged U-shaped cavities. The opposite sides of the first cleaning plate 21 and the third cleaning plate 23 are the first cleaning surface 3 and the third cleaning surface 5 respectively. The first cleaning surface 3 and the third cleaning surface 5 are arranged opposite to each other. The side wall of the second cleaning surface 4 is the second cleaning surface 4. The first cleaning surface 3 is equipped with outer bristles 6, the second cleaning surface 4 is equipped with occlusal surface bristles 7, and the third cleaning surface 5 is equipped with inner bristles 8. The outer bristles 6 and the inner bristles 8 are both inclined toward the occlusal surface bristles 7, and the occlusal surface bristles 7 are accommodated in the space between the inner bristles 8 and the second cleaning surface 4.

[0020] A flipping structure is arranged between the first cleaning plate 21 and the brush handle 1, and the flipping structure includes a flipping seat 9 and a flipping end 10. The flipping seat 9 is provided with a movable groove 901, and the inner wall of the movable groove 901 is provided with a centering shaft 902. The flipping end 10 is penetrated by a centering hole 1001 for rotatably connecting the centering shaft 902. The flipping seat 9 is arranged on the first cleaning plate 21, and the flipping end 10 is arranged on the end of the brush handle 1, so that the brush head 2 can be rotatably and movably arranged on the end of the brush handle 1. Preferably, the flipping structure has another embodiment, and the flipping seat 9 is arranged on the end of the brush handle 1, and the flipping end 10 is arranged on the first cleaning plate 21.

[0021] When using this toothbrush, the user's teeth are bitten in the two U-shaped cavities so that the upper and lower occlusal surfaces of the teeth respectively abut against the two occlusal surface bristles 7, the outer side of the teeth corresponds to the outer bristles 6, and the inner side of the teeth corresponds to the inner bristles 8. Using this toothbrush can contact the outer side, inner side and occlusal surface of the teeth, achieving fast, comprehensive and effective cleaning of the entire mouth of teeth, and is more convenient to use.

[0022] The first cleaning plate 21 and the third cleaning plate 23 are both arc-shaped plate structures. When the first cleaning plate 21 contacts the flip end 10, the brush handle 1 and the brush head 2 are relatively vertical, and a docking piece 11 is provided in the middle of the third cleaning plate 23. The docking piece 11 is a T-shaped structure, and the docking piece 11 is fixedly connected to the second cleaning plate 22. Preferably, the docking piece 11 and the second cleaning plate 22 can be fixedly connected by welding, gluing, etc. A deformation structure 12 is formed at the connection between the docking piece 11 and the third cleaning plate 23, so that the two sides of the third cleaning plate 23 can be relatively elastically deformed and close to each other, so that the user can clean the gaps between the teeth in the inner area of ​​the teeth.

[0023] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
