Description
Technical field
This utility model relates to a kind of toothbrush, more particularly, relates to a kind of ultrasonic toothbrush with ultrasonic waves for cleaning function.
Background technology
Ultrasonic wave cleaning principle can be explained with " cavitation " phenomenon, so-called cavitation is the hole and forms in liquid and the hole rapid closing, when the sound wave pressure of propagating in liquid when ultrasonic vibration reaches an atmospheric pressure, hyperacoustic sound wave pressure spikes just can reach vacuum or negative pressure, but in fact not having negative pressure exists, therefore in liquid, produce a very big pressure, the liquid drawing crack is become the cavity, break when ultrasound wave pressure oppositely reaches maximum in this cavity, the intensive shock wave that produces during owing to break, this shock wave can will clash into attached to the dirt on the object.Ultrasonic amplitude only when being lower than in this bubble gas pressure, certain regional fluid pressure just can produce cavitation phenomenon, so enough could satisfy this condition greatly the time in this zone.Produce the required minimum power of cavitation and be called as the cavitation critical point.There is different cavitation critical points in different liquid, just can reach cleaning performance so ultrasonic energy must surpass this critical point.That is to say to have only the energy postcritical could produce cavitation bubble, so that carry out ultrasonic waves for cleaning.When producing cavitation phenomenon in water, hyperacoustic power density will reach 0.3W/cm
2More than.
