Orifice yingenzi ya orifice igabanya amacupa yikirahure
Orififile igabanya igikoresho gikoreshwa mugusaba amazi, mubisanzwe ikoreshwa mugutera imitwe ya parufe cyangwa ibindi bikoresho byamazi. Ibikoresho mubisanzwe bikozwe muri plastiki cyangwa reberi kandi birashobora kwinjizwa mu gufungura umutwe, bityo bikagabanya diameter yo gufungura kugirango igabanye umuvuduko namazi atemba. Iyi igishushanyo gifasha kugenzura umubare wibicuruzwa bikoreshwa, wirinde imyanda ikabije, kandi irashobora gutanga ingaruka nziza kandi imwe. Abakoresha barashobora guhitamo inkomoko ikwiye igabanya ibyo bakeneye kugirango bagere ku ngaruka ziterwa n'amazi yifuzwa, kugirango bakoreshe neza kandi birebire bimaze gukora ibicuruzwa.
