1. An electronic smoking device comprising:
a power supply, and an atomizer/liquid reservoir portion comprising a refillable liquid reservoir, and an atomizer configured to atomize a liquid stored in the liquid reservoir,
wherein the atomizer/liquid reservoir portion further comprises a liquid filling channel, an aerosol channel, and an air outlet channel, wherein the air outlet channel is at least partially separate from the liquid filling channel and the aerosol channel, wherein the liquid filling channel is configured to pass liquid into the liquid reservoir, wherein the atomizer/liquid reservoir portion comprises a coupling portion that is configured to engage with a liquid container, and wherein the air outlet channel communicates with the liquid reservoir and is configured to let pass air out of the liquid reservoir;
a first valve element that is configured, in a closed state, to prevent liquid from leaking from the liquid reservoir through the liquid filling channel, and, in an open state, to let pass liquid from the outside of the electronic smoking device through the liquid filling channel to the liquid reservoir;
a second valve element that is configured, in a closed state, to prevent liquid from leaking from the liquid reservoir through the air outlet channel, and, in an open state, to let pass air form the liquid reservoir through the air outlet channel, wherein the second valve element is configured to be shifted to an open state by coupling a liquid container to the atomizer/liquid reservoir portion.
