A kind of full range formula ultrasonic toothbrush, major part generates ultrasonic wave vibration with the combination of ceramic oscillator piece, motor, microcontroller (MCU) and battery, using the power supply of battery, light-emitting diode (LED) indicating operating status is started to act or stop by lower switch. With the frequency of the specifications design all frequency range of ceramic oscillator piece, carry out various full ranges or frequency conversion circulation, the Supersonic wave frequency rate that the vibration of ceramic oscillator piece generates can allow motor High and low frequency function or motor of not arranging in pairs or groups, and Supersonic wave frequency rate is conducted to bristle, so that oral cavity dirt is dissolved and is removed through bristle.Full range formula ultrasonic toothbrush, Hou of starting operation, motor start at full speed, and the circulation of full range Supersonic wave frequency rate is carried out under specification limit, are adjusted under all frequency range for required frequency conversion. Circulation can design pauses within a certain period of time, and vibration frequency can be from small toward being recycled greatly, according to the power for requiring definition control time and vibration ratio； Vice versa is operated from big toward small. This intention is the vibration and frequency generated with full range scheme control ultrasonic toothbrush, makes the cleaning behavior of ultrasonic toothbrush promotion more efficiently. 一種全頻式超音波牙刷，主要零件以陶瓷震盪片、馬達、微控制器(MCU)及電池的結合產生超音波振動，採用電池的供電，發光二極體(LED)指示工作狀態，按下開關即開始動作或停止。以陶瓷震盪片的規格設計全頻範圍的頻率，進行各種全頻或變頻循環，陶瓷震盪片振動產生的超音波頻率可搭配馬達高、低周波功能或不搭配馬達，將超音波頻率傳導至刷毛，透過刷毛使口腔污垢溶解及移除。全頻式超音波牙刷，開始運作後，電機全速啟動，在規格範圍下進行全頻超音波頻率的循環，在全頻範圍下針對所需要的變頻進行調整。循環可設計在一定時間內停頓，振動頻率可由小往大進行循環，依要求定義控制時間及振動比例的強弱；反之亦可由大往小進行運作。本創意乃以全頻模式控制超音波牙刷產生的振動與頻率，使超音波牙刷提升更有效率的清潔行為。
