一、紅外感應水龍頭是開環還是閉環
紅外感應(ying)水(shui)龍頭(tou)(tou)是閉環系(xi)統,因為它直接檢測使(shi)用情況,進(jin)而控制水(shui)龍頭(tou)(tou)的工作。
感應水龍頭是通過紅(hong)外(wai)線(xian)(xian)反(fan)(fan)射(she)原(yuan)理,當人體的(de)手(shou)放在水(shui)(shui)龍(long)頭的(de)紅(hong)外(wai)線(xian)(xian)區域內,紅(hong)外(wai)線(xian)(xian)發射(she)管發出(chu)的(de)紅(hong)外(wai)線(xian)(xian)由(you)于(yu)人體手(shou)的(de)摭擋反(fan)(fan)射(she)到紅(hong)外(wai)線(xian)(xian)接收管,通過集(ji)成線(xian)(xian)路(lu)內的(de)微(wei)電(dian)(dian)腦(nao)處理后的(de)信(xin)號(hao)(hao)發送(song)給(gei)脈沖電(dian)(dian)磁(ci)閥,電(dian)(dian)磁(ci)閥接受信(xin)號(hao)(hao)后按(an)指(zhi)(zhi)定的(de)指(zhi)(zhi)令打開(kai)(kai)閥芯來(lai)控制水(shui)(shui)龍(long)頭出(chu)水(shui)(shui);當人體的(de)手(shou)離開(kai)(kai)紅(hong)外(wai)線(xian)(xian)感應范圍,電(dian)(dian)磁(ci)閥沒有(you)接受信(xin)號(hao)(hao),電(dian)(dian)磁(ci)閥閥芯則通過內部的(de)彈簧進行復位(wei)來(lai)控制水(shui)(shui)龍(long)頭的(de)關水(shui)(shui)。
二、紅外感應水龍頭的水流控制屬于手動控制嗎
紅(hong)外(wai)感應水(shui)龍(long)頭的水(shui)流控(kong)制不屬于手(shou)動控(kong)制。
手(shou)動(dong)控(kong)制(zhi)(zhi)是指通過直接的人工操作來控(kong)制(zhi)(zhi)事(shi)物的工作狀態,如手(shou)動(dong)開(kai)關等。而自(zi)動(dong)感(gan)(gan)應控(kong)制(zhi)(zhi)則(ze)是通過對周圍環(huan)境的感(gan)(gan)知,自(zi)動(dong)地實現控(kong)制(zhi)(zhi)動(dong)作,不需要人工干預。
紅(hong)外(wai)感應水(shui)龍(long)頭采用(yong)(yong)紅(hong)外(wai)傳感器技術,當有(you)手或物體靠近水(shui)龍(long)頭時(shi),紅(hong)外(wai)線(xian)就會(hui)被反射回(hui)來,被接收器接收,然(ran)后(hou)傳送到(dao)芯(xin)片進行處理,芯(xin)片識別到(dao)信號(hao)后(hou)就會(hui)控制(zhi)水(shui)閥打開或關閉(bi),從(cong)而(er)實現控制(zhi)水(shui)流(liu)的作用(yong)(yong)。
相比于手動控制,紅外感應水(shui)龍頭具有很多優點,例如可以更加(jia)精準地控制水(shui)流(liu),避免浪(lang)費水(shui)資源(yuan),節約(yue)用水(shui)成本;同時(shi)還(huan)可以避免交叉感染,保證衛生,有效預防細菌傳播;還(huan)能夠提(ti)高使用體驗和方(fang)便性(xing),尤其適用于公共場所等高頻使用場景。
