Description

A kind of sound wave motor of electric toothbrush

Technical field

This utility model relates to electric toothbrush technology, particularly relates to the sound wave motor of a kind of electric toothbrush.

Background technology

Electric toothbrush is the new product occurred in recent years, has started a revolution of oral hygiene abroad.Although electric toothbrush is not still popularized in the application of China, but existing people's prediction, important a member that it will become in popular health product.Investigation display, electric toothbrush compared with ordinary toothbrush, more scientific and effective.Can more thoroughly remove dental plaque, reduce the oral diseases such as gingivitis, periodontal disease and gingival hemorrhage, also be the generally popular article of everyday use of current American-European many countries.And electric toothbrush quickly rotating or vibrations by electric core, make brush produce high-frequency vibration, toothpaste is resolved into trickle foam by moment, deeply cleans teeth space；Meanwhile, the vibration of bristle can promote the blood circulation in oral cavity, and gingiva tissue has beyond thought massage effect.

Dividing principle, electric tooth is brushed with two big classes: rotate and vibration.The toothbrush principle rotating class is simple, it is simply that motor-driven circle brush rotates, and strengthens friction effect while performing common brushing action.The toothbrush of oscillatory type is more complicated, also more high-end price.Its interior of oscillatory type has an electrically driven (operated) vibrating motor, brush can be allowed to produce to be perpendicular to the swing in high frequency in brush holder direction, but the amplitude swung is only small, is generally each 5 millimeter up and down, and the maximum amplitude of oscillation of industry is 6 millimeters.When brushing teeth, the brush of swing in high frequency can efficiently complete to scrub the action of tooth on the one hand, vibration on the other hand per minute more than 30000 times also allows the mixture of the toothpaste in oral cavity and water produce bubble small in a large number, and the pressure produced during bubble eruption can go deep into teeth space cleaning dirt.

Acoustic toothbrush refers to that the frequency of vibration of bristle/brush is consistent with frequency of sound wave or close, is therefore also sound vibration toothbrush.The use " sound wave " that not literal meaning is understood is brushed teeth, and the bristle rapid movement being similar to acoustic vibration frequency creates the superpower cleaning effect of nearly 100 times of beyond tradition manual toothbrush.But existing acoustic toothbrush frequency of vibration is unstable, it is easy to cause the halfway problem of cleaning.
