牙(ya)(ya)刷(shua)在(zai)我們(men)的生活中是必不可少(shao)的東西，在(zai)不斷變(bian)得(de)更好(hao)用，更方便(bian)的過(guo)程中，接受電(dian)(dian)動(dong)牙(ya)(ya)刷(shua)的人越來越多(duo)，人們(men)在(zai)日常的使(shi)用中證實(shi)(shi)了電(dian)(dian)動(dong)牙(ya)(ya)刷(shua)確(que)實(shi)(shi)能夠讓(rang)刷(shua)牙(ya)(ya)這件(jian)事(shi)情變(bian)得(de)很簡單，在(zai)保持牙(ya)(ya)齒(chi)清潔方面(mian)，電(dian)(dian)動(dong)牙(ya)(ya)刷(shua)也確(que)實(shi)(shi)比(bi)自己動(dong)手(shou)刷(shua)牙(ya)(ya)效果(guo)更好(hao)。

  而在(zai)科(ke)技日新(xin)月(yue)異的(de)今天，電動牙刷也出現在(zai)市場上，成為炙手可熱的(de)新(xin)產品。它和普通牙刷相比特別在(zai)哪里呢?應(ying)該就在(zai)于它的(de)“電動”二字。這種(zhong)電動的(de)原理也是特別有趣(qu)的(de)。

? 電動牙刷由什么組成的?它包括了干電池、微型直流減速電機、電(dian)(dian)(dian)(dian)(dian)池盒(he)、牙刷頭、金屬護板(ban)和(he)套筒(tong)(tong)等部件。干電(dian)(dian)(dian)(dian)(dian)池在電(dian)(dian)(dian)(dian)(dian)動牙刷使(shi)用(yong)時(shi)，是和(he)直流(liu)電(dian)(dian)(dian)(dian)(dian)機一起安裝在電(dian)(dian)(dian)(dian)(dian)池盒(he)里(li)面，用(yong)來作為直流(liu)電(dian)(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)(dian)源(yuan)。而(er)看到電(dian)(dian)(dian)(dian)(dian)動牙刷都(dou)知道，我(wo)們可以(yi)通過牙刷套筒(tong)(tong)上的開關(guan)控制電(dian)(dian)(dian)(dian)(dian)源(yuan)。其實這個電(dian)(dian)(dian)(dian)(dian)源(yuan)是從電(dian)(dian)(dian)(dian)(dian)池盒(he)里(li)延伸出來的，可以(yi)按照不(bu)同(tong)型號(hao)確定它的開關(guan)位置。
