FIG. 2 illustrates that the battery 210 , the sensor 230 , the heater 250 , and the liquid storage unit 270 are arranged in a line. However, the internal structure of the aerosol generating device 200 is not limited to that shown in FIG. 2 . In other words, according to the design of the aerosol generating device 200 , the arrangement of the battery 210 , the sensor 230 , the heater 250 , and the liquid storage unit 270 may be changed.

The battery 210 supplies power used to operate the aerosol generating device 200 . That is, the battery 210 may supply power to the heater 250 to be heated. In addition, the battery 210 may supply power required for the operation of other hardware components included in the aerosol generating device 200 , that is, the sensor 230 .

First, the user may grip the aerosol generating device 200 , bring the mouth close to the suction port 222 adjacent to the liquid storage unit 270 , and inhale air through the suction port 222 . When the user inhales air through the inlet 222 , the air outside the aerosol generating device 200 is introduced into the aerosol generating device 200 through the inlet 221 .

The sensor 230 may be connected to the battery 210 to detect an airflow inside the aerosol generating device 200 . When the sensor 230 detects an airflow exceeding the threshold value, it is considered that the user's puff has started, and the battery 210 may be electrically connected to the heater 250 . According to an embodiment, the sensor 230 may be preset to detect only an airflow in a specific direction.

3 is a view showing in detail another example of the aerosol generating device according to the present invention.

More specifically, FIG. 3 is a diagram showing the aerosol generating device described in FIG. 2 more intuitively in order to explain the effect of the present invention in more detail. The aerosol generating device according to FIG. 3 is a non-battery unit 20 and a battery 210 ) is composed of The non-battery unit 20 and the battery 210 bonded in FIG. 3 may be separated or attached after separation, and may be referred to as a first structure and a second structure, respectively. Hereinafter, for convenience of description, the following description will be made with reference to FIG. 2 .

First, the non-battery unit 20 includes an airflow sensing module 230 , a heater 250 , and a liquid storage unit 270 . The airflow sensing module 230 in FIG. 3 means the same configuration as the sensor 230 described in FIG. 2 . Hereinafter, the airflow sensing module emphasizing the functional characteristics of the sensor 230 of FIG. 2 . (230) will be referred to. In addition, for convenience of description, the heater 250 is omitted in FIG. 3 .

The airflow detection module 230 senses the airflow inside the aerosol generating device generated when the user uses the aerosol generating device, and operates in connection with the battery 210 . The airflow detection module 230 is a module equipped with an LED 290, and the airflow detection module 230 is always connected to the battery 210 to detect the airflow inside the aerosol generating device, whereas the LED ( 290) does not operate if a preset condition is not satisfied.

Referring to FIG. 3 , it can be seen that the airflow detection module 230 is a module having at least one vent hole. The airflow detection module 230 detects that the airflow inside the aerosol generating device passes through the vent of the airflow detection module 230, and when the airflow is detected, the power of the battery 210 is applied to the heater 250 and the LED 290. The heater 250 and the LED 290 are configured to be supplied with the battery 210 and a closed circuit. The battery 210 and the heater 250 connected through the closed circuit can be heated to convert the liquid transferred from the liquid storage unit 270 through the liquid delivery means into an aerosol that can be inhaled by the user, and the battery 210 and the closed circuit The LED 290 connected via flickers. The user can recognize that he or she is smoking through the aerosol generating device through the blinking LED 290, so that overall smoking satisfaction due to smoking can be improved. According to an embodiment, the LED 290 may emit light uniformly for a predetermined time without flickering.

As an optional embodiment, the airflow detection module 230 may detect an airflow in a preset direction inside the aerosol generating device. More specifically, the airflow detection module 230 selectively detects only the airflow in a specific direction among the airflows in various directions that may be generated inside the aerosol generating device, and the heater 250 and the LED 290 are connected to the battery 210 ) and closed circuit. As an example, in FIG. 3 , the airflow 222b between the battery 210 and the airflow detection module 230 passes through the vent of the airflow detection module 230 , and the airflow 222a that passes through the suction port 222 is If so, the airflow detection module 230 may detect that an airflow has occurred. Conversely, when the airflow 222a passing through the suction port 222 passes through the ventilation hole of the airflow detection module 230, the airflow detection module 230 does not detect that the airflow has effectively occurred. According to this optional embodiment, the airflow that is generated only when the user effectively inhales through the aerosol generating device, the airflow detection module 230 detects the heater 250 and the LED 290 to the battery (210) can be connected.

As another optional embodiment, the airflow detection module 230 may detect an airflow of a preset size inside the aerosol generating device. More specifically, the airflow detection module 230 selectively detects only an airflow of a certain size or more among the airflows in various directions that can be generated inside the aerosol generating device, so that the heater 250 and the LED 290 are connected to the battery 210 ) and closed circuit. According to this optional embodiment, when the airflow is generated less than the size of the airflow generated when the user effectively inhales through the aerosol generating device, the airflow detection module 230 converts the generated airflow into an effective airflow generation. By not detecting it, it is possible to prevent malfunction of the aerosol generating device.

Combining the above-described optional embodiments, the airflow detection module 230 selectively detects only an airflow of a predetermined size and direction inside the aerosol generating device, and the heater 250 and LED 290 are connected to the battery 210 and A closed circuit may also be configured.

As another optional embodiment from the above-described example, the airflow detection module 230 detects an airflow of a preset condition inside the aerosol generating device, the heater 250 and the LED 290 for different durations, respectively. It can be controlled to form a closed circuit with the battery 210 . Here, the airflow of the preset condition means at least one or more of the preset size and direction described above. More specifically, the heater 250 needs to be heated for a certain time in order to convert the aerosol generating substrate into an aerosol, and the LED 290 detects the airflow generated whenever the user inhales through the aerosol generating device and blinks. As long as it has an operating characteristic, even if an airflow is sensed inside the aerosol generating device, a better effect can be expected to operate in connection with the battery 210 for different durations. For example, after the airflow detection module 230 senses the airflow, the heater 250 forms a closed circuit with the battery 210 for 5 seconds, and the LED 290 closes the closed circuit with the battery 210 for 1 second. configurable. When each preset duration has elapsed, the airflow detection module 230 releases the closed circuit configuration between the heater 250 and the LED 290 and the battery 210 .

In the present invention, the airflow detection module 230 is always connected to the battery 210 to detect the internal airflow of the aerosol generating device, while the heater 250 and the LED 290 configure a closed circuit selectively with the battery 210. Thus, the closed circuit configuration is released when the duration has elapsed after operating for a certain period of time, but if the output voltage of the battery 210 is less than the preset output voltage, the airflow detection module 230 detects the airflow inside the aerosol generating device. The LED 290 and the battery 210 may not be configured as a closed circuit. This operation of the airflow detection module 230 is such that the airflow detection module 230 prioritizes the operation of the aerosol generating device, and the heater ( This is to cut off the power supply of the battery 210 to the LED 290 so that only the battery 210 is supplied with as much power as possible.

According to the present invention, according to the above-described embodiment, the airflow detection module 230 may temporarily and selectively form a closed circuit of the battery 210 with the heater 250 and the LED 290 . According to the above configuration, the user can feel better smoking satisfaction by visually checking the LED 290 that flashes (or emits light) appropriately whenever an inhalation action is performed through the aerosol generating device.

According to the present invention, even when the MCU is not used, the user's suction action (puff) is still sensed, and the user can be visually satisfied through the method of flickering the LED 290 according to the detection result. The LED 290 is attached to or integrated with the airflow detection module 230 to form a closed circuit with the battery 210 only temporarily according to the result of the airflow detection module 230 sensing the airflow, so that the excessive power of the battery 210 is prevent consumption.
