Device for vaporizing liquid

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.
