電(dian)動(dong)牙刷的分類 電(dian)動(dong)牙刷哪種好(hao)？怎么(me)選電(dian)動(dong)牙刷？

電動牙刷主要分類

聲波式的電動(dong)牙(ya)刷(shua)，刷(shua)毛(mao)(mao)作直(zhi)線往復運(yun)動(dong)。通過高頻率的刷(shua)毛(mao)(mao)震動(dong)，瞬間將牙(ya)膏分解為細微泡沫，從而(er)產生流動(dong)潔(jie)(jie)力。在清潔(jie)(jie)牙(ya)齒表面的同時(shi)，還能深(shen)入清潔(jie)(jie)牙(ya)縫。

旋轉式(shi)的電動(dong)牙刷(shua)，刷(shua)頭左右(you)旋轉，作(zuo)鐘擺式(shi)運動(dong)，它能(neng)在執行(xing)普通牙刷(shua)動(dong)作(zuo)的同時加強牙刷(shua)對(dui)牙齒的摩(mo)擦效果。

市面上關于(yu)這(zhe)兩種電(dian)動(dong)牙(ya)刷(shua)(shua)(shua)的比較眾說紛紜，不能單(dan)一定論哪種更(geng)好，需要(yao)結(jie)合自己的口腔情況(kuang)及(ji)刷(shua)(shua)(shua)牙(ya)習慣進行選擇。從清(qing)潔效(xiao)果來說，已有實驗表(biao)明，這(zhe)兩種電(dian)動(dong)牙(ya)刷(shua)(shua)(shua)的清(qing)潔效(xiao)果都比手動(dong)牙(ya)刷(shua)(shua)(shua)好，其中旋轉型又比聲(sheng)波式(shi)更(geng)好一些(xie)。

但另一方面，也有實驗(yan)指出，旋轉型磨對牙齒(chi)的磨損比聲波式大，而且當聲波型的震動頻率達到30000次/分鐘時(shi)，它們清(qing)潔(jie)牙齒(chi)表面的效果差不多。在清(qing)潔(jie)牙縫(feng)上，聲波型反而要(yao)優于旋轉型。

現(xian)在中高端的聲(sheng)波牙刷振動(dong)頻率一般都在31000以上，且聲(sheng)波牙刷的振動(dong)模式更(geng)貼(tie)合(he)日常刷牙習慣，使用更(geng)安(an)全，因此從使用感受(shou)和清潔效(xiao)果(guo)來(lai)說，聲(sheng)波牙刷都要更(geng)受(shou)大眾青睞。

電動牙刷的工作原理

聲(sheng)(sheng)波式(shi)電(dian)(dian)動(dong)(dong)(dong)牙(ya)(ya)刷(shua)(shua)：其實要(yao)說(shuo)明下，聲(sheng)(sheng)波只是一個概念。這類(lei)電(dian)(dian)動(dong)(dong)(dong)牙(ya)(ya)刷(shua)(shua)利(li)用(yong)電(dian)(dian)磁驅動(dong)(dong)(dong)微型電(dian)(dian)機高速運(yun)動(dong)(dong)(dong)，帶(dai)動(dong)(dong)(dong)刷(shua)(shua)頭和(he)(he)刷(shua)(shua)毛(mao)高速左右擺動(dong)(dong)(dong)，產生機械振(zhen)動(dong)(dong)(dong)。因為(wei)帶(dai)動(dong)(dong)(dong)產生的高頻(pin)振(zhen)動(dong)(dong)(dong)和(he)(he)聲(sheng)(sheng)波的振(zhen)動(dong)(dong)(dong)頻(pin)率相近，故叫做聲(sheng)(sheng)波電(dian)(dian)動(dong)(dong)(dong)牙(ya)(ya)刷(shua)(shua)。

旋轉(zhuan)式電(dian)動(dong)牙刷：此類(lei)電(dian)動(dong)牙刷的(de)運轉(zhuan)比(bi)較(jiao)簡單(dan)，單(dan)純的(de)利用小型電(dian)機帶動(dong)刷頭做類(lei)似鐘擺的(de)左右旋轉(zhuan)運動(dong)。

電動牙刷的構成配件

一般電動(dong)牙(ya)刷構成按(an)主次可以分(fen)為機身(shen)、刷頭兩部分(fen)。

其(qi)中機(ji)身又由電(dian)(dian)機(ji)、電(dian)(dian)板(ban)、電(dian)(dian)池、護板(ban)、套筒、充電(dian)(dian)底座(zuo)等部分組成(cheng)，而電(dian)(dian)機(ji)、電(dian)(dian)板(ban)、電(dian)(dian)池、刷毛維系了(le)電(dian)(dian)動牙刷的四大核心技術。

電機：目(mu)前微型電機技術分為兩大類(lei)別。

第一類：有(you)齒(chi)輪的(de)傳統電機動(dong)力輸出(chu)系統，這(zhe)類微(wei)型電機的(de)動(dong)力性(xing)能遠遠超越了電動(dong)牙刷的(de)動(dong)力，其振動(dong)可(ke)以達(da)到(dao)20000-30000次/分鐘，缺點是噪(zao)音大，能量損耗大。

第(di)二類(lei)：非齒(chi)輪(lun)動(dong)(dong)力(li)輸出(chu)磁懸動(dong)(dong)力(li)系統(tong)，這個技(ji)術是微型電(dian)(dian)機(ji)動(dong)(dong)力(li)輸出(chu)最新的(de)(de)成果，突破(po)了傳統(tong)電(dian)(dian)動(dong)(dong)機(ji)械傳動(dong)(dong)原(yuan)理(li)，可持續穩(wen)(wen)定產生無(wu)機(ji)械摩(mo)擦的(de)(de)高頻聲波(bo)振動(dong)(dong)，所(suo)輸出(chu)的(de)(de)能量(liang)比帶齒(chi)輪(lun)的(de)(de)微型電(dian)(dian)機(ji)更(geng)強(qiang)勁(jing)、更(geng)穩(wen)(wen)定、更(geng)環保。是目(mu)前該(gai)領(ling)域的(de)(de)最尖端技(ji)術。

目前聲波(bo)電(dian)動(dong)牙刷的(de)振動(dong)次數區間在(zai)10000次-40000次每分(fen)鐘。而(er)數據展示為權(quan)衡清潔程(cheng)度(du)以及牙齒磨(mo)損(sun)程(cheng)度(du)，中高端的(de)電(dian)動(dong)牙刷振動(dong)維(wei)持在(zai)30000次左右每分(fen)鐘的(de)。

電(dian)(dian)(dian)板(ban)：電(dian)(dian)(dian)路(lu)板(ban)的(de)功(gong)(gong)能(neng)(neng)(neng)強弱，決定了電(dian)(dian)(dian)動牙(ya)刷(shua)賦值功(gong)(gong)能(neng)(neng)(neng)的(de)復(fu)雜與否。在維(wei)系牙(ya)刷(shua)正常工(gong)作(zuo)的(de)前提下，主要賦予了切換模式功(gong)(gong)能(neng)(neng)(neng)、定時(shi)功(gong)(gong)能(neng)(neng)(neng)、區域(yu)提示功(gong)(gong)能(neng)(neng)(neng)、壓力感(gan)應功(gong)(gong)能(neng)(neng)(neng)等(deng)等(deng)。一般越(yue)貴的(de)電(dian)(dian)(dian)動牙(ya)刷(shua)，其賦值的(de)功(gong)(gong)能(neng)(neng)(neng)也就會越(yue)多。

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)：充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動牙(ya)刷的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)可分為鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)與(yu)鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。相比較(jiao)兩者而言，鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)使用率會更(geng)(geng)高。其一是因為鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容量比較(jiao)大，續航(hang)時間更(geng)(geng)長，能達到2-3周以上。其二也是最(zui)重要(yao)的(de)一點(dian)是相比較(jiao)鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)更(geng)(geng)加安(an)全——重金屬對于身體的(de)危(wei)害就不細說了，何況電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動牙(ya)刷還每(mei)日在嘴巴里面倒騰的(de)。

而外置電(dian)(dian)池(chi)的話種(zhong)類就比(bi)較繁多了：鋅錳(meng)電(dian)(dian)池(chi)、鎳氫電(dian)(dian)池(chi)、鎳鎘電(dian)(dian)池(chi)等，相(xiang)對來說供(gong)能不夠穩定(ding)，影響清潔效果與使用(yong)體驗。

刷頭：由刷毛與刷頭柄(bing)組成。由于電(dian)(dian)動牙刷的(de)(de)高頻率(lv)使得對(dui)于刷毛的(de)(de)質量(liang)要求(qiu)較高，一般好一點的(de)(de)都是用杜邦軟毛。其(qi)次(ci)，刷毛的(de)(de)磨(mo)圓(yuan)率(lv)也不容小(xiao)覷(qu)：國家(jia)標(biao)準牙刷磨(mo)圓(yuan)率(lv)需要達到30%以上，而電(dian)(dian)動牙刷由于其(qi)特(te)殊性，需要要求(qiu)更高。小(xiao)編建議使用磨(mo)圓(yuan)率(lv)達到70%以上的(de)(de)刷毛以減少對(dui)于牙齒(chi)的(de)(de)損傷。
