一、為什么干手器能自動開關

自(zi)(zi)動(dong)(dong)(dong)(dong)開(kai)關(guan)是(shi)(shi)指人(ren)(ren)體紅外智能(neng)(neng)感(gan)(gan)應(ying)(ying)開(kai)關(guan)，是(shi)(shi)一種當(dang)有(you)人(ren)(ren)從紅外感(gan)(gan)應(ying)(ying)探測區域經(jing)過而自(zi)(zi)動(dong)(dong)(dong)(dong)啟動(dong)(dong)(dong)(dong)的(de)(de)(de)開(kai)關(guan)。那么(me)干(gan)手(shou)器(qi)原理是(shi)(shi)什(shen)么(me)呢(ni)？干(gan)手(shou)器(qi)能(neng)(neng)自(zi)(zi)動(dong)(dong)(dong)(dong)開(kai)關(guan)是(shi)(shi)因(yin)為(wei)(wei)在干(gan)手(shou)器(qi)內(nei)部(bu)，安裝(zhuang)了變容式(shi)自(zi)(zi)動(dong)(dong)(dong)(dong)感(gan)(gan)應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)(dian)路，由它(ta)控制著一個電(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)平衡(heng)電(dian)(dian)(dian)(dian)(dian)(dian)路。電(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)平衡(heng)電(dian)(dian)(dian)(dian)(dian)(dian)路由四部(bu)分(fen)(fen)組成，稱為(wei)(wei)四個橋(qiao)臂(bei)。變容式(shi)自(zi)(zi)動(dong)(dong)(dong)(dong)感(gan)(gan)應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)(dian)路組成了其中的(de)(de)(de)一個橋(qiao)臂(bei)。它(ta)的(de)(de)(de)感(gan)(gan)應(ying)(ying)部(bu)分(fen)(fen)，安裝(zhuang)在干(gan)手(shou)器(qi)的(de)(de)(de)出風(feng)(feng)口處(chu)。當(dang)濕手(shou)在風(feng)(feng)口下(xia)出現(xian)時，因(yin)為(wei)(wei)人(ren)(ren)體是(shi)(shi)導(dao)體，也能(neng)(neng)形成電(dian)(dian)(dian)(dian)(dian)(dian)容，于是(shi)(shi)，使(shi)感(gan)(gan)應(ying)(ying)部(bu)分(fen)(fen)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容量發(fa)生變化，立(li)即使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)橋(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)路中的(de)(de)(de)四個橋(qiao)臂(bei)的(de)(de)(de)量值，從平衡(heng)轉向不平衡(heng)。原來在平衡(heng)狀(zhuang)態下(xia)，橋(qiao)臂(bei)中能(neng)(neng)互相(xiang)抵消的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流，不再抵消，出現(xian)了一股(gu)新的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流。它(ta)能(neng)(neng)使(shi)吸鐵繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)動(dong)(dong)(dong)(dong)作，接通風(feng)(feng)扇和電(dian)(dian)(dian)(dian)(dian)(dian)熱器(qi)上的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，就會有(you)風(feng)(feng)吹出來。

二、干手器安裝高度

干(gan)手(shou)(shou)器的(de)安裝高度一般是在(zai)1.2m左(zuo)右(you)，離洗手(shou)(shou)臺30-40cm遠(yuan)。如(ru)果安裝在(zai)家(jia)中就要考慮使用人群，一般家(jia)用型的(de)掛(gua)式感受求可(ke)(ke)以(yi)根據家(jia)人的(de)平(ping)均(jun)身高來安裝，如(ru)果有小孩可(ke)(ke)以(yi)選擇安裝落地式向上的(de)干(gan)手(shou)(shou)器。

三、干手器有輻射嗎

一般通電的(de)東西都會有電離輻射(she)的(de)，只是(shi)輻射(she)大小的(de)問題(ti)，干手器也是(shi)有輻射(she)的(de)，不(bu)(bu)(bu)過不(bu)(bu)(bu)用擔心，畢竟它(ta)的(de)體量(liang)并不(bu)(bu)(bu)大，并且(qie)你只是(shi)使用不(bu)(bu)(bu)到(dao)半分鐘(zhong)，基本不(bu)(bu)(bu)會被輻射(she)所影響。

四、如何挑選干手器

挑選干手器主要根據自己的需要和環境等情況來決定是選以風為主熱量為輔的風量型的干手器，還是以熱量為主的熱風型干手器。此外，還需要考慮到干手器的外殼材質、重量、顏色、啟動原理、安裝方式、工作噪音、運行功率、干手時風溫等參數。購買的干手器品牌要(yao)有(you)質量保障，以用起來舒適為宜。
