Abstract
This flavor inhaler is provided with a housing having an air flow path that spans continuously from an inlet to an outlet, and an atomizing part for atomizing an aerosol source without accompanying combustion of the aerosol source, wherein at least one portion of the air flow path is an aerosol flow path which is a flow path for an aerosol generated from the atomizing part, and the air blow resistance of the whole air flow path is not greater than 25 mmAq.
Claims19
A flavor inhaler comprising:
- a housing having an air flow path continuous from an inlet to an outlet;
- an atomizer configured to atomize an aerosol source without burning the aerosol source;
- a switch for supplying a power source output to the atomizer during a period a user performs an inhaling action while not supplying the power source output to the atomizer during a period the user does not perform the inhaling action;
- a sensor configured to output a response value that changes in accordance with the inhaling action of the user,
- wherein at least a part of the air flow path includes an aerosol flow path which is a flow path of an aerosol generated from the atomizer,
- wherein a resistance-to-draw of the entire air flow path is 25 mmAq or less,
- wherein the resistance-to-draw of the entire air flow path is defined as pressure loss at a time of performing inhalation at 1050 mL/min by a vacuum pump at a state that the flavor inhaler is connected to the vacuum pump,
- wherein the switch operates based on the response value output from the sensor,
- wherein the housing has a first hollow provided at a side same with the inlet and the outlet relative to the sensor, and a second hollow provided at an opposite side of the inlet and the outlet relative to the sensor, and
- wherein the first hollow and the second hollow are partitioned not to communicate with each other within the housing.
