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)寶又被稱(cheng)為(wei)電(dian)(dian)熱(re)餅，里面填充是保(bao)溫(wen)棉(mian)，采用雙控溫(wen)電(dian)(dian)熱(re)儲能(neng)式結構，逐(zhu)漸釋放熱(re)能(neng)。內設自(zi)(zi)動(dong)過熱(re)保(bao)護裝(zhuang)置及(ji)自(zi)(zi)動(dong)保(bao)溫(wen)指示裝(zhuang)置，一(yi)個由PTC熱(re)敏電(dian)(dian)阻開(kai)關(guan)控制的(de)小電(dian)(dian)爐(lu)，PTC是正溫(wen)度(du)系數的(de)熱(re)敏電(dian)(dian)阻，當電(dian)(dian)流通過時自(zi)(zi)身會發(fa)熱(re)（電(dian)(dian)爐(lu)的(de)熱(re)量(liang)也(ye)會傳導給它(ta)的(de)），當溫(wen)度(du)到達一(yi)定值時，它(ta)的(de)電(dian)(dian)阻會急劇增大，可以視為(wei)斷(duan)開(kai)，所以熱(re)寶此時停(ting)止(zhi)消耗電(dian)(dian)能(neng)，之后靠保(bao)溫(wen)棉(mian)對(dui)電(dian)(dian)爐(lu)的(de)保(bao)溫(wen)來緩慢放熱(re)。

2、軟質液體暖手寶原理

軟質(zhi)液體暖(nuan)手(shou)寶有(you)電(dian)(dian)(dian)(dian)極(ji)(ji)式和電(dian)(dian)(dian)(dian)熱(re)元件(jian)式兩大類(lei)，是在固(gu)體電(dian)(dian)(dian)(dian)熱(re)餅(bing)的基礎(chu)上改進的。電(dian)(dian)(dian)(dian)極(ji)(ji)式暖(nuan)手(shou)寶采用電(dian)(dian)(dian)(dian)極(ji)(ji)式加熱(re)方法，具有(you)優(you)質(zhi)控(kong)溫(wen)與(yu)熱(re)熔斷器(qi)雙重溫(wen)控(kong)保險。正常(chang)情(qing)況(kuang)下袋內液體溫(wen)度達到65度時溫(wen)控(kong)器(qi)會(hui)自動(dong)切斷電(dian)(dian)(dian)(dian)路(lu)，停止加熱(re)，而一旦溫(wen)控(kong)器(qi)控(kong)制失靈，熱(re)熔斷器(qi)切斷電(dian)(dian)(dian)(dian)源，終止加熱(re)，需(xu)更換新產品，請(qing)不要嘗試修復。由于(yu)電(dian)(dian)(dian)(dian)極(ji)(ji)式電(dian)(dian)(dian)(dian)暖(nuan)寶由于(yu)兩個電(dian)(dian)(dian)(dian)極(ji)(ji)，直接裸露在水中(zhong)，造成的漏電(dian)(dian)(dian)(dian)風險很大，已經被禁(jin)用。

電(dian)熱(re)(re)元件(jian)式暖手(shou)寶(bao)里面有(you)爐絲作為電(dian)阻，是一袋液體和兩個金屬(shu)片構成的。暖手(shou)寶(bao)里面的液體是過飽和溶(rong)(rong)液，輕輕彎曲(qu)(qu)袋中金屬(shu)片，彎曲(qu)(qu)金屬(shu)片時產生的輕微(wei)震動會使溶(rong)(rong)質(zhi)結晶(jing)，而結晶(jing)的過程會釋(shi)放熱(re)(re)量(liang)，這樣(yang)就達到了(le)取(qu)暖的目(mu)的。這種暖手(shou)寶(bao)溫度(du)可達50℃左右，可維(wei)持約1小時。

3、電池式暖手寶原理

電(dian)(dian)(dian)池(chi)式暖(nuan)手寶使用(yong)(yong)內(nei)置鋰電(dian)(dian)(dian)池(chi)或(huo)者是5號(hao)電(dian)(dian)(dian)池(chi)進行供(gong)電(dian)(dian)(dian)驅動，利(li)用(yong)(yong)電(dian)(dian)(dian)阻產生熱(re)量的(de)原理進行暖(nuan)手。電(dian)(dian)(dian)池(chi)式暖(nuan)手寶對(dui)比前兩種類型，加熱(re)方(fang)式不受市(shi)電(dian)(dian)(dian)供(gong)電(dian)(dian)(dian)加熱(re)的(de)約束，可(ke)將溫度迅速提升至40℃以內(nei)，只有(you)將內(nei)置鋰電(dian)(dian)(dian)池(chi)型充滿電(dian)(dian)(dian)，就可(ke)以在需要時開啟使用(yong)(yong)，而采用(yong)(yong)5號(hao)電(dian)(dian)(dian)池(chi)型則更(geng)方(fang)便，可(ke)隨(sui)時隨(sui)地更(geng)換(huan)電(dian)(dian)(dian)池(chi)，尤其適合外出(chu)。

二、暖手寶有哪些特點

暖手寶(bao)特(te)點是什(shen)么？
