Cartridge having partition member and heater and inhaler including same
To provide an inhaler cartridge and an inhaler including a novel structure. Provided is a cartridge for an inhaler. The cartridge includes: a housing including an accommodation space capable of accommodating a liquid, an air flow passage, and a partition member partitioning the accommodation space and the air flow passage in a longitudinal direction; and a heater configured to be capable of heating the liquid and arranged in the air flow passage. The partition member includes an opening opened in a transverse direction to bring the accommodation space into communication with the air flow passage. The opening includes an upstream-side opening edge and a downstream-side opening edge. The partition member includes an upstream-side end and a downstream-side end. A distance between the upstream-side opening edge and the upstream-side end is smaller than a distance between the downstream-side opening edge and the downstream-side end.
1. A cartridge for an inhaler, the cartridge comprising:
a housing including an accommodation space capable of accommodating a liquid, an air flow passage, and a partition member partitioning the accommodation space and the air flow passage in a longitudinal direction; and
a heater configured to be capable of heating the liquid and arranged in the air flow passage,
wherein the partition member includes an opening opened in a transverse direction to bring the accommodation space into communication with the air flow passage,
wherein the opening includes an upstream-side opening edge and a downstream-side opening edge,

wherein a distance between the upstream-side opening edge and the upstream-side end is smaller than a distance between the downstream-side opening edge and the downstream-side end,
wherein the heater includes an upstream-side heater end and a downstream-side heater end, and
wherein a distance between the upstream-side heater end and the upstream-side end is smaller than a distance between the downstream-side heater end and the downstream-side end.
2. The cartridge according to claim 1 , wherein the partition member includes an upstream portion positioned between the upstream-side opening edge and the upstream-side end and a downstream portion positioned between the downstream-side opening edge and the downstream-side end, and
wherein a longitudinal length of the downstream portion is longer than a longitudinal length of the upstream portion.
3. The cartridge according to claim 1 , comprising:
a liquid holding member arranged to cover the opening,
wherein the liquid holding member is arranged between the opening and the heater.
4. The cartridge according to claim 1 , wherein the housing includes an air outlet port communicating with the air flow passage.
5. The cartridge according to claim 1 , comprising:
an air inlet port provided at a position facing the heater and communicating with the air flow passage.
6. An inhaler comprising:
the cartridge according to claim 1 ; and
a battery portion configured to supply electric power to the heater of the cartridge.
