AI Technical Summary

Problems solved by technology

[0002] Using existing ordinary toothbrushes, people are accustomed to doing horizontal reciprocating movements, which cannot clean the gap between the teeth; using existing electric toothbrushes, the bristles swing or vibrate back and forth on the surface of the teeth, and it is impossible to clean the gap between the teeth thoroughly; and these toothbrushes are also easy to damage the gums and oral cavity , After long-term use, dental calculus will form around the teeth, so you have to go to the hospital every year to find a doctor to clean your teeth

[0003] Especially for children, they cannot control the brushing action correctly, causing the toothbrush to "rampage" in the oral cavity. As a result, the brushing is not clean, and it is easy to damage the gums and oral cavity.

[0004] None of the existing toothbrushes have automatic cleaning and drying functions. The residues and water stains on the bristles after brushing can easily lead to the growth and reproduction of bacteria, resulting in oral diseases, gastrointestinal diseases, odontogenic sinusitis and other diseases.

[0005] The ideal way to brush your teeth is to brush vertically along the direction between the teeth, and at the same time brush horizontally along the direction of the gingival sulcus. When brushing the upper teeth, brush downwards, and when brushing the lower teeth, brush upwards; all current toothbrushes cannot achieve this well. this method

[0006] Chinese invention patent (notification number CN203138734U) discloses an electric toothbrush. Although it has the function of brushing vertically along the direction between the teeth when brushing teeth, it also has shortcomings. The disadvantage is that the brush head and the transmission part are fixedly connected. , the horizontal brushing function of brushing along the gingival sulcus cannot be realized
