Refill diverter for electronic cigarette
View Patent ↗A refillable atomizing assembly with a liquid reservoir for an electronic cigarette. The assembly includes a housing and a mouthpiece that is removably engaged to the housing. A liquid reservoir is disposed within the housing, and separated from the aerosol outlet by an outlet chamber. The liquid reservoir is refillable by removing the mouthpiece and dispensing the liquid into the outlet chamber. An atomizing chamber is adjacent to the reservoir and opposite of the outlet chamber. An aerosol conduit connects the atomizing chamber to the outlet chamber. An isolation member is disposed within the outlet chamber. A liquid passage through the isolation member allows the liquid placed into the outlet chamber to flow into the reservoir. A shield portion of the isolation member is located about the aerosol conduit to prevent liquid from entering. An aerosol vent through the shield portion enables the flow of the aerosol therethrough.
1. An atomizing assembly with a liquid reservoir, which is refillable, for an electronic cigarette, comprising:
a housing;
a mouthpiece with an aerosol outlet formed therethrough, removably engaged with said housing;

10. The assembly of claim 1 , and wherein:
said aerosol conduit includes an extension that extends further into said outlet chamber than said liquid reservoir, and wherein;
said shield portion accommodates said extension.
11. The assembly of claim 1 , and wherein:
said shield portion is configured as a cap over an end of said aerosol conduit.
12. The assembly of claim 1 , and wherein:
said aerosol vent is aligned along an axis substantially perpendicular to said aerosol conduit.
13. The assembly of claim 1 , and wherein:
said aerosol vent is disposed radially away from an open end of said aerosol conduit.
14. An atomizing assembly with a liquid reservoir, which is refillable, for an electronic cigarette, comprising:
