摘要：
A scent dispensing device is disclosed. The scent dispensing device has a housing that has a cavity which forms an interior of the housing and separates the interior from an external environment. The cavity may be sized and dimensioned to receive at least one scent cartridge. The housing may have a number of apertures that each provide a respective flow path between the interior of the housing and the external environment. A number of selectively permeable membranes may be positioned in the flow paths. The selectively permeable membranes may selectively block moisture from reaching the interior of the housing from the external environment and may permit passage of gas between the interior of the housing and the external environment including passage of at least one scent from the interior of the housing to the external environment.
