Figures 5A to 5C are schematic diagrams showing airflow inside the aerosol generating device 200 according to the inhalation mode according to one embodiment. In one embodiment, the aerosol-generating device 200 may include two or more inhalation modes, with FIG. 5A showing the first inhalation mode, FIG. 5B showing the second inhalation mode, and FIG. 5C showing the third inhalation mode. This is a schematic diagram.

Referring to FIG. 5A showing the first inhalation mode, the aerosol (A) generated in the aerosol generating unit 230 of the aerosol generating device 200 according to an embodiment is divided into the first compartment ( 240-1) and may be delivered to the user's mouth via the mouthpiece 220 (see arrow F1 in FIG. 5A). At this time, the airflow blocking film 250 may be placed in a second position to block the lower end of the second compartment 240-2 so that the aerosol A can completely flow into the first compartment 240-1. In the first inhalation mode, the aerosol (A) generated in the aerosol generating unit 230 is delivered to the mouthpiece through the cavity of the first compartment (240-1), and the user inhales the aerosol (A) to inhale the aerosol (A). The medium contained within can be inhaled.

Referring to FIG. 5B showing the second inhalation mode, the aerosol (A) generated in the aerosol generating unit 230 of the aerosol generating device 200 according to one embodiment is in the second compartment of the airflow path compartment 240 ( 240-2) and may be delivered to the user's mouth via the mouthpiece 220 (see arrow F2 in FIG. 5B). At this time, the airflow blocking film 250 may be placed in the first position to block the lower end of the first compartment 240-1 so that the aerosol A can completely flow into the second compartment 240-2. In the second inhalation mode, the aerosol (A) generated in the aerosol generating unit 230 passes through the second compartment (240-2) and is delivered to the mouthpiece along with oxygen gas, so that the user inhales the aerosol (A) to inhale the aerosol ( A) Additional oxygen can be inhaled along with the medium contained within.

Referring to FIG. 5C illustrating the third inhalation mode, no aerosol is generated from the aerosol generating unit 230, and when the user inhales, external air enters the aerosol generating device 200 through the perforation 260 on the housing. The outside air flows into the interior and may be moved to the mouthpiece 220 through the second compartment 240-2 of the airflow path compartment 240. The perforation 260 according to one embodiment may be disposed between a position corresponding to the aerosol generating unit 230 and a position corresponding to the airflow path partition unit 240 on the housing 210. According to one embodiment, the perforation is placed at the corresponding position on the housing 210, so that the airflow introduced from the outside can transfer oxygen from the second compartment 240-2 to the user's mouth.

At this time, the airflow blocking film 250 may be placed in the second position to block the lower end of the first compartment 240-1 so that the aerosol A can completely flow into the second compartment 240-2. In the third inhalation mode, the user can inhale only oxygen vaporized with external air. Users can achieve the effect of relieving accumulated stress by inhaling oxygen.

Hereinafter, a method of recognizing the user's stress level through the stress detection sensor 270 and controlling whether or not oxygen is inhaled and the amount of inhaled oxygen according to the position of the airflow blocking film 250 will be described.

In one embodiment, the aerosol generating device 200 may include a stress detection sensor 270 and an LED 280. The stress detection sensor 270 according to one embodiment may evaluate the user's stress index by recognizing the user's sweat, heart rate, and/or blood pressure. When the user's finger is placed on the stress detection sensor 270 according to one embodiment, the stress index may be evaluated by detecting sweat, heart rate, and/or blood pressure from the user's finger. The LED 280 according to one embodiment may display the stress index evaluated by the stress detection sensor 270 in the color of the light of the LED 280 and convey it to the user. For example, if the stress index is evaluated as low, LED 280 may emit green light, if the stress index is evaluated as medium, LED 280 may emit yellow light, and if the stress index is evaluated as high, LED 280 may emit green light. LED 280 can emit red light.

In one embodiment, the position of the airflow blocking film 250 may change depending on the stress index measured by the stress detection sensor 270. For example, when the stress index is low and the LED 280 emits green light, the airflow blocking film 250 is disposed in the first position to block the second compartment 240-2 so that the airflow is blocked by the oxygen-based agent. 2 It can be transferred to the user's mouth without passing through compartment 240-2 at all. For example, when the stress index is high and the LED 280 emits red light, the air flow blocking film 250 is disposed in the second position to block the first compartment 240-1 to prevent the air flow containing the oxygen base. An airflow with a high oxygen content passing through the second compartment 240-2 may be transferred to the user's mouth. For example, when the stress index is at a medium level and the LED 280 emits yellow light, the airflow blocking film 250 is disposed between the first compartment 240-1 and the second compartment 240-2 to block the airflow. An airflow containing a medium level of oxygen may pass through a portion of the second compartment 240-2 containing an oxygen substrate and be transferred to the user's mouth.
