In order to provide that additives can be used without bringing the additives in contact with an atomizer (26) of the atomizer/liquid reservoir portion (14), the invention provides an additive reservoir (40) for the electronic smoking device (10), which comprises an additive storage volume (42), a through hole (44) and an additive outlet opening (46) that opens the additive storage volume (42) to the through hole (44). Furthermore, the invention provides that the atomizer/liquid reservoir portion (14) comprises a receiving section (36) for the additive reservoir (40). ## Claims ### Claim 1 An electronic smoking device comprising: an air inhalation port; an atomizer/liquid reservoir portion comprising: a liquid reservoir, and an atomizer adapted to atomize a liquid stored in the liquid reservoir; an air duct configured to guide atomized liquid from the atomizer towards the air inhalation port; a receiving section located at a back end of the atomizer/liquid reservoir portion; and an additive reservoir removably attachable to the receiving section, the additive reservoir comprising: an additive storage volume, a through hole extending through the additive reservoir and being configured to communicate with the air duct to guide atomized liquid to the air inhalation port, and an additive outlet opening that opens the additive storage volume to the through hole. ### Claim 2 (depends on 1) The electronic smoking device according to claim 1, wherein the additive reservoir is provided between the air inhalation port and the liquid reservoir. ### Claim 3 (depends on 2) The electronic smoking device according to claim 2, wherein the additive outlet opening is arranged at a distance to the atomizer. ### Claim 4 (depends on 2) The electronic smoking device according to claim 2, wherein the liquid reservoir and the additive reservoir are provided adjacent to each other. ### Claim 5 (depends on 1) The electronic smoking device according to claim 1, wherein the additive reservoir is received in the receiving section. ### Claim 6 (depends on 5) The electronic smoking device according to claim 5, wherein the additive reservoir portion comprises a protrusion that projects from the receiving section. ### Claim 7 (depends on 1) The electronic smoking device according to claim 1, wherein the through hole of the additive reservoir has a maximum inner diameter that corresponds to the inner diameter of the air duct. ### Claim 8 (depends on 1) The electronic smoking device according to claim 1, wherein the additive reservoir comprises an additive supply duct that extends from an outer lateral side of the additive reservoir through the additive outlet opening into the through hole. ### Claim 9 (depends on 8) The electronic smoking device according to claim 8, wherein the additive supply duct is formed as a straight duct and completely extends through the additive reservoir. ### Claim 10 (depends on 1) The electronic smoking device according to claim 1, wherein the additive reservoir comprises a wick that extends through the additive outlet opening into the through hole. ### Claim 11 (depends on 10) The electronic smoking device according to claim 10, wherein the wick extends from the through hole in opposite directions into different sections of the additive storage volume. ### Claim 12 (depends on 1) The electronic smoking device according to claim 1, wherein the through hole comprises a constricting section in which a diameter of the through hole decreases, wherein the additive outlet opening opens into the constricting section. ### Claim 13 (depends on 12) The electronic smoking device according to claim 12, wherein in the constricting section, the through hole is formed by a first and a second pair of opposite lateral side sections, wherein the opposite lateral side sections of the first pair are tapered towards each other and the opposite lateral side sections of the second pair are tapered less towards each other than the opposite lateral side sections of the first pair. ### Claim 14 (depends on 13) The electronic smoking device according to claim 13, wherein the additive outlet opening is arranged in one of the lateral side sections of the second pair.
