如何對(dui)(dui)電(dian)動(dong)牙刷實現IPX7防水等級測(ce)試的(de)檢(jian)(jian)驗?采(cai)用氣體(ti)為(wei)介質的(de)IPX防水檢(jian)(jian)測(ce)設備。對(dui)(dui)于電(dian)動(dong)牙刷的(de)防水檢(jian)(jian)測(ce)，只需要做一個相對(dui)(dui)密封的(de)工裝，把電(dian)動(dong)牙刷放入工裝內，采(cai)用50KPA的(de)檢(jian)(jian)測(ce)壓力，保壓2秒，測(ce)試3秒，泄漏值不超60PA為(wei)合格。這也是(shi)(shi)目前(qian)大部(bu)分(fen)廠家采(cai)用的(de)防水檢(jian)(jian)測(ce)方(fang)案，即(ji)IPX7防水檢(jian)(jian)測(ce)，如是(shi)(shi)別的(de)IPX防水等級也同(tong)樣(yang)適用，只不過(guo)是(shi)(shi)檢(jian)(jian)測(ce)參數(shu)不同(tong)而(er)已(yi)。

如(ru)何操作密(mi)封(feng)測(ce)試(shi)(shi)儀(yi)：一、安(an)裝、調試(shi)(shi)，1、將(jiang)有機(ji)玻璃筒放到(dao)機(ji)箱上(shang)。2、將(jiang)壓(ya)力(li)(li)穩(wen)定(ding)的(de)(de)(de)壓(ya)縮氣源與密(mi)封(feng)測(ce)試(shi)(shi)儀(yi)“壓(ya)縮空氣”的(de)(de)(de)進(jin)氣管(底座后端(duan)左側位(wei)置(zhi))相連接，并連接真(zhen)空輸出(底座后端(duan)右側位(wei)置(zhi))和有機(ji)玻璃桶上(shang)的(de)(de)(de)快(kuai)速接頭(tou)。3、向筒內注入一定(ding)量的(de)(de)(de)清水(shui)，高(gao)度至(zhi)壓(ya)板面(mian)以上(shang)約10mm處(但加入試(shi)(shi)驗樣品(pin)后不能讓水(shui)被吸出)。4、蓋好(hao)有機(ji)玻璃筒的(de)(de)(de)密(mi)封(feng)蓋，將(jiang)密(mi)封(feng)測(ce)試(shi)(shi)儀(yi)上(shang)的(de)(de)(de)開(kai)(kai)關(guan)(guan)撥至(zhi)開(kai)(kai)的(de)(de)(de)位(wei)置(zhi)，并調整測(ce)試(shi)(shi)儀(yi)的(de)(de)(de)控制(zhi)調節旋鈕，首(shou)先(xian)確定(ding)旋鈕是否鎖定(ding)(即處于按下(xia)的(de)(de)(de)狀態)，無錫板，若鎖定(ding)，進(jin)行調節時需要(yao)稍用力(li)(li)先(xian)將(jiang)旋鈕向上(shang)拔起(qi)，然后旋轉進(jin)行調節，金(jin)屬(shu)雙極板，并觀察(cha)真(zhen)空壓(ya)力(li)(li)表(biao)，將(jiang)壓(ya)力(li)(li)調整至(zhi)您(nin)所(suo)需要(yao)的(de)(de)(de)數(shu)值上(shang)。將(jiang)測(ce)試(shi)(shi)儀(yi)上(shang)的(de)(de)(de)開(kai)(kai)關(guan)(guan)撥至(zhi)關(guan)(guan)的(de)(de)(de)位(wei)置(zhi)，關(guan)(guan)閉氣路(lu)開(kai)(kai)始(shi)保壓(ya)并計時。調節至(zhi)所(suo)需穩(wen)定(ding)壓(ya)力(li)(li)后，即將(jiang)旋鈕按下(xia)，以固定(ding)好(hao)位(wei)置(zhi)。5、結束后，膜電極，將(jiang)密(mi)封(feng)測(ce)試(shi)(shi)儀(yi)上(shang)的(de)(de)(de)開(kai)(kai)關(guan)(guan)撥至(zhi)開(kai)(kai)的(de)(de)(de)位(wei)置(zhi)，打開(kai)(kai)密(mi)封(feng)蓋把(ba)試(shi)(shi)樣取出，雙極板，放入下(xia)一組(zu)試(shi)(shi)樣開(kai)(kai)始(shi)下(xia)一組(zu)測(ce)試(shi)(shi)儀(yi)。
