電吹風是常用(yong)(yong)(yong)的(de)(de)小家(jia)電(dian)，由于電(dian)熱(re)絲(si)(si)發熱(re)功(gong)率大，發熱(re)集中，其連接部分很(hen)容易松動。常見(jian)的(de)(de)連接方(fang)法(fa)是用(yong)(yong)(yong)黃(huang)(huang)銅(tong)(tong)鉚釘將電(dian)熱(re)絲(si)(si)等導(dao)線鉚緊在云母板上(shang)。黃(huang)(huang)銅(tong)(tong)、鎳鉻絲(si)(si)、銅(tong)(tong)導(dao)線三者的(de)(de)熱(re)膨脹系數不同，使(shi)(shi)用(yong)(yong)(yong)一段時間(jian)后(hou)鉚接點(dian)就會(hui)(hui)松動，導(dao)致接觸不良(liang)甚至打火(huo)。找(zhao)一根醫用(yong)(yong)(yong)１０號以(yi)上(shang)的(de)(de)不銹鋼注射針頭，切(qie)取5～10ｍｍ長(chang)(chang)的(de)(de)一小段，穿卡在原來(lai)的(de)(de)黃(huang)(huang)銅(tong)(tong)鉚釘孔中作支(zhi)點(dian)。因(yin)為紫銅(tong)(tong)的(de)(de)熱(re)脹系數比不銹鋼大，當溫度升高后(hou)不但不會(hui)(hui)松動，反而(er)會(hui)(hui)接觸得更緊，筆者用(yong)(yong)(yong)此法(fa)修理過多(duo)種電(dian)熱(re)器件都很(hen)成(cheng)功(gong)，長(chang)(chang)時間(jian)使(shi)(shi)用(yong)(yong)(yong)導(dao)電(dian)都十(shi)分良(liang)好(hao)。

電吹風構成部件:

電吹風一般由殼體、電動機、風葉、電熱元件、手柄和開關等部件構成。電吹風的(de)殼體一般(ban)采(cai)(cai)用(yong)(yong)薄鐵板或銅板沖制(zhi)焊接，再鍍(du)上(shang)鎳鉻，也有(you)(you)的(de)采(cai)(cai)用(yong)(yong)工程塑料壓制(zhi)而成(cheng)。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)的(de)核心(xin)部件，一般(ban)采(cai)(cai)用(yong)(yong)串激式(shi)、罩極式(shi)和永磁(ci)式(shi)三種(zhong)。采(cai)(cai)用(yong)(yong)罩極式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)風(feng)(feng)(feng)(feng)速低，但風(feng)(feng)(feng)(feng)溫高，故適應于(yu)吹(chui)(chui)(chui)干(gan)濕(shi)發(fa)和整理發(fa)型(xing)；采(cai)(cai)用(yong)(yong)串激式(shi)和永磁(ci)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)風(feng)(feng)(feng)(feng)速高而風(feng)(feng)(feng)(feng)溫低，更適應于(yu)吹(chui)(chui)(chui)塵及物品(pin)烘干(gan)等。永磁(ci)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)工作電(dian)(dian)(dian)(dian)(dian)(dian)壓較(jiao)低，且是(shi)直流，這需要增加(jia)降壓整流裝(zhuang)置。電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)的(de)風(feng)(feng)(feng)(feng)葉(xie)(xie)(xie)大都安(an)裝(zhuang)在電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的(de)軸端(duan)上(shang)，位于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)的(de)尾部，有(you)(you)金(jin)屬扇葉(xie)(xie)(xie)和塑料扇葉(xie)(xie)(xie)兩種(zhong)。電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)元件一般(ban)采(cai)(cai)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)絲繞制(zhi)而成(cheng)，電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)絲有(you)(you)扁形和圓線兩種(zhong)，裝(zhuang)在電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)(chui)風(feng)(feng)(feng)(feng)的(de)出風(feng)(feng)(feng)(feng)口附(fu)近(jin)。工作時，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)帶(dai)動(dong)扇葉(xie)(xie)(xie)旋轉(zhuan)，由吸(xi)風(feng)(feng)(feng)(feng)口吸(xi)入冷(leng)風(feng)(feng)(feng)(feng)，然后由出風(feng)(feng)(feng)(feng)口吹(chui)(chui)(chui)出。

電吹風的(de)開(kai)(kai)關(guan)的(de)撓(nao)板(ban)式(shi)、推桿式(shi)和按鈕式(shi)三種，一般有“熱風(feng)”、“冷風(feng)”和“停”三擋，用不同(tong)的(de)顏(yan)色作標記；白色表(biao)示“停止”，紅(hong)色表(biao)示送(song)(song)“熱風(feng)”，藍色表(biao)示送(song)(song)“冷風(feng)”。電(dian)動機旋轉時(shi)，若開(kai)(kai)關(guan)置“冷風(feng)”位(wei)置，這(zhe)時(shi)電(dian)熱元(yuan)件是(shi)斷開(kai)(kai)的(de)，出(chu)風(feng)口(kou)吹(chui)(chui)出(chu)的(de)是(shi)冷風(feng)；若置“熱風(feng)”位(wei)置，這(zhe)時(shi)電(dian)熱元(yuan)件是(shi)接通(tong)的(de)，則吹(chui)(chui)出(chu)的(de)是(shi)熱風(feng)。
