Abstract (en)

[origin: WO2020222087A1] Device (100) for vaporising liquid (216). The device (100) comprises a housing (102) and a pressure regulating member (206). The housing (102) defines a chamber (210) to store liquid (216), and the member (206) is engaged to the chamber (210). A first portion (206a) of the member (206) is exposed to the chamber (210), while a second portion (206b) is exposed to atmospheric pressure. The member (206) comprises of porous material, which absorbs the liquid (216), without any external energy input, when pressure inside the chamber (210) is sufficient to allow liquid (216) to partially overcome air barrier, without allowing the liquid (216) to leak into the atmosphere. Further, the material allows air from the atmosphere to enter the chamber (210) when pressure inside the chamber (210) drops to an extent that allows air to at least partially overcome liquid barrier formed by liquid (216) within some of the pores.
