Description

Intelligent toothbrush

Technical Field

The invention relates to the technical field of toiletries, and particularly provides an intelligent toothbrush.

Background

The current intelligent toothbrushes can be divided into two main types, namely a rotary intelligent toothbrush and a vibration intelligent toothbrush according to the working principle. The intelligent toothbrush is simple in principle, the motor is used for driving the round brush head to rotate, the friction effect is enhanced when the traditional brushing action is executed, the toothbrush is loud in use, the tooth surface can be cleaned cleanly, tooth gaps and the inside of teeth are cleaned relatively weakly, the abrasion to the teeth is large, the effort is not recommended, the toothbrush is not used for a long time, the toothbrush is relatively rare in the market, and the toothbrush is mainly used for dental treatment. The principle of the vibration type intelligent toothbrush is relatively complex, and the vibration type intelligent toothbrush can be divided into a common electric toothbrush and an ultrasonic toothbrush according to the structure of the vibration type intelligent toothbrush. The ultrasonic toothbrush is characterized in that an ultrasonic vibration motor is arranged in the toothbrush, a motor rotating shaft is fixedly connected with the brush head, the brush head can generate high-frequency swing perpendicular to the direction of the brush handle, but the swing amplitude is very small, generally about 5mm, and the maximum amplitude in industry is not more than 6mm. On the one hand, the high-frequency swinging brush head can efficiently finish the tooth brushing action during tooth brushing, and on the other hand, more than ten thousands of vibrations per minute can also enable the mixture of toothpaste and water in the oral cavity to generate a large number of tiny bubbles, and the pressure generated during bubble bursting can penetrate into the gaps between teeth to clean dirt. Vibration type toothbrushes are widely used in the market and are becoming more and more intelligent.

The vibration type intelligent toothbrush is divided into two types according to the brush head, namely the traditional brush head type and the tooth socket type. The traditional toothbrush head is similar to a traditional toothbrush, the tooth brushing mode is similar, the tooth brushing needs to be finished by hands, the difference is that the toothbrush head of the toothbrush is vibrated or swung, the intelligent toothbrush technology is relatively mature, and the tooth brushing experience and effect are good, so that the toothbrush is the main stream type of the intelligent toothbrush at present. The intelligent toothbrush of the tooth socket type is also called as a lazy toothbrush, and is a product which appears recently, and a user can finish tooth brushing automatically only by putting the tooth socket into the oral cavity and biting the tooth socket without using hands to assist in the tooth brushing process. Unlike conventional brush heads, the dental sleeve is a full-tooth contact type brush, and when the dental sleeve is snapped, the bristles cover the inner and outer surfaces of teeth and the grinding surface, and brush teeth by vibration and swing of the bristles. The volume of the toothbrush head is larger, most of used materials are soft rubber materials, the soft rubber transmission efficiency is lower, and the vibration attenuation is more obvious as the distance between the toothbrush head and a motor shaft is longer. The user can only drive the brush hair to vibrate and swing after putting the toothbrush into the oral cavity to bite the toothbrush, so that the toothbrush can be ensured to be clean, and the simple connection of the toothbrush and the motor is difficult to meet the requirement. The existing intelligent toothbrushes like tooth sleeves on the market are basically formed by directly connecting the tooth sleeves with a motor, when the tooth sleeves are taken as a whole to be placed in the mouth and snapped, the tooth sleeves can not swing any more in the oral cavity and can only vibrate, the vibration transmitted to the brush hair is very little, when the tooth sleeves are snapped forcefully, the vibration of the far end of the tooth sleeves is basically disappeared, the brush hair is basically in a static state, the effect of brushing teeth can not be achieved, and a user can only experience the effect of brushing teeth only when the toothbrush motor vibrates and teeth are not brushed. Therefore, the biggest bottleneck of the intelligent toothbrush like a dental floss is that the toothbrush cannot thoroughly clean the toothbrush and the experience effect is poor, and the main reason is that the vibration quantity and the swing quantity of the brush hair cannot be ensured.
