Ndemanga kuchokera kwa wowunika pazamalonda

Anzanga, kumayambiriro kwa autumn, ndikhoza kale kuneneratu kwa inu: nyengo yakumapeto kwa chaka ichi idzakhala yotanganidwa kwambiri. Mitambo yolemera iyenera kuyembekezera kuthambo padziko lonse lapansi ndipo mosakayikira cholakwika chidzakhala ndi atomizer yomwe tigawanitse lero: OBS Engine.

Kwa iwo omwe akutsatira, OBS yalowa m'malo osangalatsa kudziko la atomization ndi Crius yomwe idachita zambiri kuposa kungogwira msewu. Pokondedwa ndi ena, odetsedwa ndi ena, atomizer iyi idali kalambulabwalo wa kutsitsimuka kwa RTA chifukwa idayika mkamwa mwa aliyense kuthekera kotulutsa mitambo ya nthunzi yokhuthala ndikusunga tanki yothandiza kwambiri yodzilamulira. Kuyambira nthawi imeneyo, ochita nawo mpikisano asokoneza gulu, Griffin ndi nyama zina zopuma. 

Kuti tipeze peloton, OBS imatipatsa pano Injini yokhala ndi dzina lokonzedweratu. Zowonadi, kukula kwake mu nthunzi kumabweretsa pafupi kwambiri ndi Fardier de Cugnot kuposa tiyi wamba. Injini ya nthunzi? Ili ndiye lingaliro lokondedwa kwa wopanga. Ndipo ndikumva kuti chiyeso chopanganso chozizwitsa chamalonda cha Crius chinamupangitsa kuti aphunzire mozama asanatiyike chinthu ichi kwa ife.

Choyamba, Injini ndi yokongola.

Chabwino, chabwino. Izi ndizodziwikiratu, blah blah, ato sichina koma chidutswa chachitsulo, blah blah…. Koma ine, ndimapeza kuti ndizotentha, zowonetsedwa bwino komanso zokwanira kuti zisiyanitsidwe bwino ndi kuchuluka kwa ma atomizer amtundu womwewo. Zopezeka muzitsulo kapena zakuda, simupeza mitundu yachilendo pano. Mwachiwonekere, ngati mukufuna kuti ikhale yofiira, pentani ndikuwunikanso pa Vape Motion: "Pimp My Atty!".

25mm m'mimba mwake, ndi mwana wokongola, osati wamtali kwambiri. Titha kuganiza kale kuti msonkhano pa seti sudzakhala ululu, ndizo kale. Gawo lakumtunda likuwonetsa kale kuti mpweya umatengedwa pansi pa nsonga yodontha, chipewa chapamwamba chimakhala chachikulu komanso chozungulira mu chrome ndipo chimakhala ndi dzina lachizindikiro mbali zonse ziwiri.

Pakatikati, timapeza thanki ya quartz yomwe imawoneka yolimbikitsidwa kuchokera mkati ndi mizati yachitsulo. Ndikukayika kuti izi zitha kubweretsa chopinga chilichonse pakugwa, koma kumverera kolimba (monga timanenera m'dziko lamagalimoto) kumalimbikitsidwa. Lang'anani, muli ndi thanki yachiwiri ngati cholowa m'malo ngati mutayamba shuga wa sitiroberi ndikugwetsa ato yanu. Mkati, timalingalira kale belu lalikulu lokhala ndi "Engine” lolembedwapo. 

Pansi, timapeza chipewa chapansi chachikhalidwe, chopanda chilichonse kupatula ma grooves ochepa kuti athandizire kugwira.  

Kukongola koteroko kumakhala koyenera komanso kokulirapo ndipo, mumtundu wake wakuda, Nouvel Obs sikuphwanya gawo la masomphenya chifukwa imalinganiza mbali zojambulidwa ndi chrome kapena zitsulo bwino kwambiri.

Ubwino womaliza uli pamwamba pa kukayikira pamtengo wofunsidwa. Ulusiwu ndi wosavuta kumva, zomangira zosiyanasiyana zimachitika mwachilengedwe. Zigawo zosuntha za ato zomwe ndi mphete ya mpweya kapena kapu yodzaza ndizomwe zili pamwamba, zimagwira ntchito kwambiri komanso zoganiziridwa bwino. Mwina pali zabwinoko potengera kuchuluka kwa zinthu, koma, kutengera kukula kwa Injini, kusankha kwazinthu zina zabwino, zotsutsana ndi kusinthidwa kolondola, zikuwoneka kuti ndizoyenera kusakhala ndi ato 500gr kumapeto kwa bokosi. !

Mphamvu yotsatsa ndi 5.2ml. Ndikutsamira kwambiri ku 5ml max, kapena kuchepera, koma ndiyenera kukayikira pang'ono ...

Ndemanga za Reviewer pa magwiridwe antchito

Pankhani ya magwiridwe antchito, Injini yakhala ndi zodzaza.

Tiyamba ndi zomwe zikadakhala zoyipitsitsa: kutulutsa mpweya kuchokera pamwamba pa atomizer. Ok, ndili ngati inu, ndinali wonyinyirika. Ndikumvetsetsa lingaliro lomwe ndi kupewa kutayikira kulikonse koma, m'mbuyomu, ma atomizer ena omwe ali ndi zida zotere amatha kusokoneza kuti ndi mpweya wamba womwe ungavutike nawo komanso kukhala ndi vuto loziziritsa ma koyilo ndikupangira nthunzi zina. kuposa otentha. Komabe, OBS yagwirapo ntchito mozama kwambiri ndipo tiyenera kuvomereza kuti zotsatira zake ndi zodabwitsa.

Tiyeni tifotokoze mwachidule: chimney chomwe chimachokera kuchipinda chopanda mpweya kupita kumtunda wodontha chimakhala ndi makoma awiri omwe amatsimikizira mipata iwiri kapena ma ducts. Yoyamba, yofunsidwa ndi pakamwa pako pokoka mpweya, imatumiza mpweya kuchipinda, chomwe chimaziziritsa zozungulira ndikudutsa chachiwiri kupita ku nsonga yodontha. Monga kujambula bwino kuli bwino kusiyana ndi kufotokozera kwautali, mudzapeza mu chithunzi pansipa mfundo ya ntchito. 

Ubwino wake ndikuti pokhapokha mutapumira mozondoka, simungakhale ndi kutayikira kulikonse kapena zochitika za condensation. Mpaka pano, kuipa kwa kachitidwe kameneka kunali kuti mpweya wabwino womwe umapangidwira nthawi zambiri unali wosakwanira komanso kuti pa mphamvu yaikulu, yofunikira kugwedeza koyilo iwiri, nthunzi inali yotentha, ngakhale yotentha kwambiri kuti igwiritsidwe ntchito bwino.

Apa, palibe, chilichonse chikuwoneka kuti chikukulitsidwa bwino kwambiri kuti chisasunthike mokhazikika ndipo Injini imayika mawonekedwe akusintha pang'ono chifukwa, kuyambira pano mpaka mtsogolo, kukhala ndi ma airholes pamwamba pa atomizer sikumaloledwanso kukhala ndi mpweya wokwanira. Ndipo ngakhale moona mlengalenga.

Chinthu chachiwiri chowoneka bwino kwambiri, chipewa chapamwamba chikutsetsereka, kuchokera pamwamba mpaka pansi ndipo, pamalo okwera, chimasonyeza dzenje lalikulu lodzaza. Zinali zosavuta koma ndimayenera kuziganizirabe. Ndingowonjezera kuti opaleshoniyo ndi chisangalalo chenicheni cha chitonthozo. Palibe kukakamiza kopitilira muyeso, ndi batala. Zoonadi, pamene mpweya umatengedwa kuchokera pamwamba, palibe chifukwa chotsutsa chifukwa cha kudzazidwa kosasamala.

Palibe chifukwa choti mutembenuzire mphete yosinthira yongoyerekeza yamadzimadzi chifukwa palibe. Ndipo ndine wokondwa kwambiri ndi izo, kuyambira pa mfundo yomwe si yopusa ngati mukuganiza za izo, kuti atomizer mwina angathe kufalitsa mtundu uliwonse wa madzi kapena ayi. Ndipo sichowonadi chokulitsa mabowo omwe angamupangitse kukhala wokonda kumeza VG ngati sangathe kapena kuchoka ku 80/20 ngati kuli kofunikira. Apa pali, m'malingaliro mwanga, chinthu chopusa chifukwa, monga mukudziwa, mwina mumakwera kwambiri VG ndipo mumafunikira mtundu wina wa ato, kapena mumatsika mulingo wa VG wotsika ndipo mumafunika wina. Nthawi, zina zonse ndi zokopa zamalonda.  

Chinthu chachitatu chomwe chimapangitsa Injini kukhala yodziwika bwino ndi mfundo zake zamphamvu. Sireyi ya Velocity ili pa kapu yapansi, yokwezeka mamilimita angapo ndipo chimbudzi chimakhazikika pachipewa chapamwamba. Ndi pamene mphambano ziwirizi zikuchitika pamene chipinda chimakhala hermetic. Chifukwa chake pali zipilala ziwiri pa chimney zomwe ziyenera kuphatikizidwa muzitsulo ziwiri zomwe zimaperekedwa kuti izi zitheke pa mbale ndiyeno kupukuta kungachitike. Ndipo, ngati zikuwoneka zovuta kufotokozedwa monga choncho, zenizeni, ndizosavuta komanso pafupifupi zokha. 

Chifukwa chake, capillary imagwera mu thanki ya kapu yapansi yomwe ili pansipa ndikudyetsa ma koyilo popanda vuto. Popeza chipinda chopanda mpweya nthawi zonse chimakhala choyimitsidwa ndikudzazidwa ndi mpweya, madzi samalowa m'chipindacho atapanikizika, pokhapokha ngati mutalimbikitsidwa kutero mukapanga vacuum ndi kuyimba kwapakamwa. Ndizofanana ndi tank dripper system kupatula kuti madzi omwe ali mu thanki akupitirizabe kudyetsa thankiyi ndi mphamvu yokoka. Madziwo amatuluka kudzera m'malekezero anayi a thonje omwe amagwera mumadzi mpaka mbale kuti isungunuke ndi ma coils. Apanso, tili ndi mfundo yosavuta, yakuthupi, yomwe imagwira ntchito mwangwiro.

Zomwe zili ndi Drip-Tip

• Drip Tip Attachment Type: 510 Only
• Kukhalapo kwa Drip-Tip? Inde, vaper imatha kugwiritsa ntchito mankhwalawa nthawi yomweyo
• Utali ndi mtundu wa nsonga yodontha: Yaifupi

Ndemanga kuchokera kwa owunika okhudzana ndi Drip-Tip

Dongosolo lomwe limaperekedwa lidapangidwa kuti lizigwira ntchito ndi Injini, limamva nthawi yomweyo mukalitenga pakamwa.

Wopangidwa ndi POM (polyoxymethylene), zinthu zomwe zimagonjetsedwa ndi kugwedezeka kwa makina, dzimbiri ndi mankhwala ndipo zimatha kupirira kutentha kwakukulu, ndizosangalatsa komanso zoyenera kuti "mtambo" ugwire ntchito pa chipangizocho. Wina akhoza kukayikira mphamvu yake pozindikira kuti imagwiritsa ntchito kukonza kosavuta kwa 510 komanso kuti m'mimba mwake yamkati, yomwe imafanana ndi chitoliro chapakati cha chimney, sichili chachikulu kwambiri koma chimagwira ntchito bwino, ku ungwiro, kukhala. moona mtima, ngakhale pansi pa mikhalidwe yoyesa ya mphamvu zapamwamba.  

Ndimangowona zolakwika ziwiri zazing'ono. Ndizovuta kutuluka m'nyumba yake chifukwa cha mawonekedwe ake ndipo imatenthedwabe pakapita nthawi ya chain-vaping. Chitonthozo poganiza kuti cholumikizira cha 510 chikhala ndi mtundu uliwonse wa nsonga yodontha.
