一、暖手寶的原理是什么

1、硬質固體暖手寶原理

硬質固體暖手(shou)寶又(you)被稱為(wei)電(dian)(dian)熱(re)(re)餅，里面填充是保(bao)溫棉，采用雙(shuang)控溫電(dian)(dian)熱(re)(re)儲能式(shi)結構(gou)，逐漸釋(shi)放熱(re)(re)能。內設自動(dong)過熱(re)(re)保(bao)護裝(zhuang)(zhuang)置及自動(dong)保(bao)溫指示裝(zhuang)(zhuang)置，一(yi)個由PTC熱(re)(re)敏電(dian)(dian)阻(zu)開關控制(zhi)的(de)小(xiao)電(dian)(dian)爐，PTC是正(zheng)溫度(du)系數的(de)熱(re)(re)敏電(dian)(dian)阻(zu)，當電(dian)(dian)流通過時(shi)自身(shen)會(hui)發熱(re)(re)（電(dian)(dian)爐的(de)熱(re)(re)量(liang)也會(hui)傳(chuan)導給它的(de)），當溫度(du)到(dao)達一(yi)定值時(shi)，它的(de)電(dian)(dian)阻(zu)會(hui)急劇增大，可(ke)以(yi)視為(wei)斷開，所以(yi)熱(re)(re)寶此(ci)時(shi)停止消耗電(dian)(dian)能，之后(hou)靠保(bao)溫棉對電(dian)(dian)爐的(de)保(bao)溫來緩慢(man)放熱(re)(re)。

2、軟質液體暖手寶原理

軟質液(ye)體(ti)暖手寶(bao)有電(dian)(dian)極式(shi)(shi)和電(dian)(dian)熱元件式(shi)(shi)兩(liang)大(da)類，是在固(gu)體(ti)電(dian)(dian)熱餅(bing)的(de)基礎上改(gai)進的(de)。電(dian)(dian)極式(shi)(shi)暖手寶(bao)采用電(dian)(dian)極式(shi)(shi)加熱方(fang)法，具(ju)有優質控溫(wen)(wen)與熱熔(rong)(rong)斷器(qi)(qi)雙重溫(wen)(wen)控保險。正常情況下袋內液(ye)體(ti)溫(wen)(wen)度(du)達到65度(du)時溫(wen)(wen)控器(qi)(qi)會(hui)自(zi)動切斷電(dian)(dian)路，停止加熱，而一旦(dan)溫(wen)(wen)控器(qi)(qi)控制失(shi)靈，熱熔(rong)(rong)斷器(qi)(qi)切斷電(dian)(dian)源，終止加熱，需更換新(xin)產品，請不(bu)要(yao)嘗試修復(fu)。由于電(dian)(dian)極式(shi)(shi)電(dian)(dian)暖寶(bao)由于兩(liang)個電(dian)(dian)極，直(zhi)接(jie)裸露在水中，造成的(de)漏電(dian)(dian)風險很大(da)，已經被禁(jin)用。

電熱元件式暖(nuan)手寶里(li)面有爐絲(si)作為電阻(zu)，是(shi)一袋液體和兩個金(jin)屬片(pian)構成的。暖(nuan)手寶里(li)面的液體是(shi)過飽和溶(rong)液，輕(qing)(qing)輕(qing)(qing)彎曲(qu)袋中金(jin)屬片(pian)，彎曲(qu)金(jin)屬片(pian)時產生的輕(qing)(qing)微震動會使溶(rong)質結晶，而結晶的過程會釋放熱量，這(zhe)樣就達到了(le)取暖(nuan)的目(mu)的。這(zhe)種暖(nuan)手寶溫度(du)可(ke)達50℃左右，可(ke)維持約(yue)1小時。

3、電池式暖手寶原理

電(dian)(dian)(dian)(dian)池(chi)式(shi)暖手(shou)(shou)寶(bao)使(shi)用(yong)內置(zhi)(zhi)鋰電(dian)(dian)(dian)(dian)池(chi)或(huo)者是5號電(dian)(dian)(dian)(dian)池(chi)進行供電(dian)(dian)(dian)(dian)驅(qu)動，利用(yong)電(dian)(dian)(dian)(dian)阻產生熱(re)量的原(yuan)理(li)進行暖手(shou)(shou)。電(dian)(dian)(dian)(dian)池(chi)式(shi)暖手(shou)(shou)寶(bao)對比前兩種類型(xing)，加熱(re)方式(shi)不受市電(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)加熱(re)的約束(shu)，可將溫度迅速提升(sheng)至40℃以內，只(zhi)有將內置(zhi)(zhi)鋰電(dian)(dian)(dian)(dian)池(chi)型(xing)充滿電(dian)(dian)(dian)(dian)，就可以在需要時開啟(qi)使(shi)用(yong)，而(er)采(cai)用(yong)5號電(dian)(dian)(dian)(dian)池(chi)型(xing)則更方便，可隨時隨地更換電(dian)(dian)(dian)(dian)池(chi)，尤其適(shi)合外出。

二、暖手寶有哪些特點
