Abstract: Device for vaporising liquid. 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 to partially overcome air barrier, without allowing the liquid 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.

Abstract: A device comprises a housing, a vaporization zone, a power source assembly, and a first connecting member. The housing comprises a first air flow path enabling flow of air from entry of the air into the housing to exit of the air from the housing. The vaporization zone provided in the housing to vaporise the liquid is disposed in the first air flow path. A power source assembly operably coupled to the housing comprises a second air flow path enabling the flow of air from entry of the air into the housing to exit of the air from the housing. The first connecting member establishes a fluidic communication between the first air flow path and the second air flow path and comprises a flexible member. The flexible member is deformable and reform-able, to compensate for gap between the housing and the power source assembly when coupled.
