電吹風是常用(yong)(yong)(yong)的(de)小家電(dian)，由(you)于電(dian)熱(re)(re)(re)絲發熱(re)(re)(re)功率大，發熱(re)(re)(re)集中，其連接部分很容(rong)易松(song)動。常見(jian)的(de)連接方法是用(yong)(yong)(yong)黃(huang)(huang)銅(tong)(tong)鉚釘將(jiang)電(dian)熱(re)(re)(re)絲等導(dao)線鉚緊(jin)在云母板上。黃(huang)(huang)銅(tong)(tong)、鎳鉻絲、銅(tong)(tong)導(dao)線三(san)者的(de)熱(re)(re)(re)膨脹(zhang)系數不(bu)(bu)同，使(shi)(shi)用(yong)(yong)(yong)一(yi)段(duan)時間(jian)后鉚接點(dian)就會(hui)(hui)松(song)動，導(dao)致接觸不(bu)(bu)良(liang)甚至(zhi)打火。找一(yi)根(gen)醫用(yong)(yong)(yong)１０號(hao)以(yi)上的(de)不(bu)(bu)銹鋼(gang)注射針頭，切取5～10ｍｍ長的(de)一(yi)小段(duan)，穿卡在原來(lai)的(de)黃(huang)(huang)銅(tong)(tong)鉚釘孔中作支點(dian)。因為紫銅(tong)(tong)的(de)熱(re)(re)(re)脹(zhang)系數比(bi)不(bu)(bu)銹鋼(gang)大，當溫度升高后不(bu)(bu)但不(bu)(bu)會(hui)(hui)松(song)動，反(fan)而會(hui)(hui)接觸得更緊(jin)，筆者用(yong)(yong)(yong)此法修理過多種電(dian)熱(re)(re)(re)器件都很成功，長時間(jian)使(shi)(shi)用(yong)(yong)(yong)導(dao)電(dian)都十分良(liang)好。

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(yi)般(ban)采用(yong)薄鐵板或銅(tong)板沖制焊接，再鍍上鎳鉻，也有的(de)采用(yong)工程塑(su)料(liao)壓(ya)制而成(cheng)。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)的(de)核心(xin)部件(jian)，一(yi)般(ban)采用(yong)串激(ji)(ji)式、罩極式和(he)永磁(ci)式三種(zhong)。采用(yong)罩極式電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機的(de)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)風(feng)(feng)(feng)(feng)(feng)速(su)低(di)，但風(feng)(feng)(feng)(feng)(feng)溫高，故適應(ying)于吹(chui)(chui)干濕發(fa)和(he)整(zheng)理發(fa)型；采用(yong)串激(ji)(ji)式和(he)永磁(ci)式電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機的(de)電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)風(feng)(feng)(feng)(feng)(feng)速(su)高而風(feng)(feng)(feng)(feng)(feng)溫低(di)，更適應(ying)于吹(chui)(chui)塵及(ji)物品烘干等。永磁(ci)式電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機工作電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)較低(di)，且是(shi)直流(liu)，這需(xu)要增加降壓(ya)整(zheng)流(liu)裝(zhuang)置。電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)的(de)風(feng)(feng)(feng)(feng)(feng)葉大都(dou)安裝(zhuang)在電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機的(de)軸端上，位于電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)的(de)尾部，有金屬扇(shan)葉和(he)塑(su)料(liao)扇(shan)葉兩(liang)種(zhong)。電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)熱元件(jian)一(yi)般(ban)采用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)熱絲(si)繞(rao)制而成(cheng)，電(dian)(dian)(dian)(dian)(dian)(dian)熱絲(si)有扁(bian)形和(he)圓線兩(liang)種(zhong)，裝(zhuang)在電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)(chui)風(feng)(feng)(feng)(feng)(feng)的(de)出(chu)風(feng)(feng)(feng)(feng)(feng)口(kou)附(fu)近。工作時，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機帶動(dong)扇(shan)葉旋(xuan)轉，由(you)吸風(feng)(feng)(feng)(feng)(feng)口(kou)吸入冷(leng)風(feng)(feng)(feng)(feng)(feng)，然后由(you)出(chu)風(feng)(feng)(feng)(feng)(feng)口(kou)吹(chui)(chui)出(chu)。

電吹風的(de)開(kai)關(guan)的(de)撓板式、推桿式和按鈕(niu)式三種，一般有(you)“熱(re)風(feng)(feng)”、“冷(leng)(leng)(leng)風(feng)(feng)”和“停(ting)”三擋(dang)，用(yong)不同的(de)顏(yan)色(se)作(zuo)標記；白色(se)表示(shi)“停(ting)止”，紅(hong)色(se)表示(shi)送“熱(re)風(feng)(feng)”，藍色(se)表示(shi)送“冷(leng)(leng)(leng)風(feng)(feng)”。電(dian)動機旋轉(zhuan)時，若開(kai)關(guan)置(zhi)“冷(leng)(leng)(leng)風(feng)(feng)”位(wei)置(zhi)，這時電(dian)熱(re)元(yuan)件是(shi)(shi)斷開(kai)的(de)，出風(feng)(feng)口吹出的(de)是(shi)(shi)冷(leng)(leng)(leng)風(feng)(feng)；若置(zhi)“熱(re)風(feng)(feng)”位(wei)置(zhi)，這時電(dian)熱(re)元(yuan)件是(shi)(shi)接通的(de)，則(ze)吹出的(de)是(shi)(shi)熱(re)風(feng)(feng)。
