Therefore, it can be understood by those of ordinary skill in the art related to the present embodiment that other general-purpose components other than the components shown in FIG. 2 may be further included in the aerosol generating apparatus 200.

In FIG. 2, the battery 210, the sensor 230, the heater 250, and the liquid storage unit 270 are shown as being 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 so that the heater 250 can be heated. In addition, the battery 210 may supply other hardware components included in the aerosol generating apparatus 200, that is, power required for the operation of the sensor 230.

The aerosol generating device 200 may include a sensor 230. In an embodiment, the sensor 230 may include a puff detection sensor. The puff detection sensor may detect a user's puff based on any one of a temperature change, a flow change, a voltage change, and a pressure change.

The sensor 230 detects an airflow inside the aerosol generating device 200, and when an airflow of more than a preset value is detected, the battery 210 and the heater 250 are electrically connected.

The heater 250 is electrically connected to the battery 210 by the sensor 230 to receive power from the battery 210. The heater 250 supplied with power from the battery 210 may raise the temperature of the liquid aerosol-generating substrate included in the liquid storage unit 270.

The liquid storage unit 270 may contain an aerosol-generating material. The liquid storage unit 270'accommodating an aerosol-generating material' therein means that the liquid storage unit 270 simply performs a function of containing an aerosol-generating material, such as the use of a container, and the liquid storage unit ( It means including an element impregnating (containing) an aerosol-generating material such as sponge, cotton, cloth, or porous ceramic structure in the interior of 270).

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

More specifically, FIG. 3 is a more intuitive view of the aerosol generating apparatus described in FIG. 2 in order to describe the effects of the present invention in more detail. The aerosol generating apparatus according to FIG. 3 includes a non-battery unit 20 and a battery 210. ). The non-battery unit 20 and the battery 210 bonded in FIG. 3 may be separated or bonded 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 detection module 230, a heater 250, and a liquid storage unit 270. The air sensing module 230 in FIG. 3 refers to the same configuration as the sensor 230 described in FIG. 2, and hereinafter, the sensor 230 in FIG. 2 is an airflow sensing module emphasizing functional characteristics. It will be referred to as (230). In addition, the heater 250 is omitted in FIG. 3 for convenience of description.

The airflow detection module 230 senses the airflow inside the aerosol generation device generated when the user uses the aerosol generation 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, while 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 ventilation 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 airflow is detected, the power of the battery 210 is supplied to the heater 250 and the LED 290. The heater 250 and the LED 290 are configured with a battery 210 and a closed circuit to be supplied. The heater 250 connected through the battery 210 and the closed circuit can be heated to convert the liquid phase 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 through flashes. The user can recognize that he is smoking through the aerosol generating device through the blinking LED 290, so that smoking satisfaction due to smoking can be improved overall. According to an embodiment, the LED 290 may emit light uniformly for a certain period of time without blinking.

As an optional embodiment, the airflow detection module 230 may detect 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 airflows in various directions that can be generated inside the aerosol generating device, so that the heater 250 and the LED 290 ) And a closed circuit. As an example, the airflow 222b between the battery 210 and the airflow detection module 230 in FIG. 3 passes through the vent of the airflow detection module 230, and the airflow 222a passing through the suction port 222 is If so, the airflow detection module 230 may detect that airflow has occurred. On the contrary, when the airflow 222a passing through the inlet 222 passes through the vent of the airflow detection module 230, the airflow detection module 230 does not effectively detect that airflow has occurred. According to this optional embodiment, the airflow detection module 230 senses the airflow generated only when the user effectively inhales through the aerosol generating device, so that the heater 250 and the LED 290 are connected to the battery. Can be connected to (210).

As another optional embodiment, the airflow detection module 230 may detect an airflow having a predetermined size inside the aerosol generating device. More specifically, the airflow detection module 230 selectively detects only airflows of a certain size or more among airflows in various directions that can be generated inside the aerosol generating device, so that the heater 250 and the LED 290 ) And a closed circuit. According to this optional embodiment, when an airflow occurs 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 effective airflow generation. By not detecting it, it is possible to prevent malfunction of the aerosol generating device.

Integrating the above-described optional embodiments, the airflow detection module 230 selectively detects only the airflow of a predetermined size and direction inside the aerosol generating device, and the heater 250 and the LED 290 are connected to the battery 210 It is also possible to configure a closed circuit.

As another optional embodiment from the above-described example, when the airflow detection module 230 detects the airflow of a preset condition inside the aerosol generating device, the heater 250 and the LED 290 are respectively configured to have different durations. It can be controlled to form a closed circuit with the battery 210. Here, the airflow of the preset condition means at least one of the above-described preset size and direction. More specifically, the heater 250 must be heated for a certain period of time in order to convert the aerosol-generating substrate into an aerosol, and the LED 290 detects and flashes the airflow generated whenever the user inhales through the aerosol-generating device. As long as it has an operating characteristic, a better effect can be expected to operate in connection with the battery 210 for different durations even if airflow is detected inside the aerosol generating device. For example, after the airflow detection module 230 senses the airflow, the heater 250 configures a closed circuit with the battery 210 for 5 seconds, and the LED 290 opens the battery 210 and the closed circuit for 1 second. Configurable. When each preset duration elapses, 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 selectively form a closed circuit with the battery 210 Thus, the closed circuit configuration is released when the duration of operation for a certain period of time elapses. However, 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 that the airflow detection module 230 prioritizes the operation of the aerosol generation device, and the heater directly involved in the aerosol generation when the life of the battery 210 is almost reached ( This is to cut off the power supply of the battery 210 to the LED 290 so that the power of the battery 210 is supplied as much as possible to only 250).

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 blinks (or emits light) appropriately whenever inhalation is performed through the aerosol generating device.

It has a feature that does not include the MCU which essentially accompanies According to the present invention, even when the MCU is not used, the user's suction behavior (puff) is still detected, and the LED 290 is flashed according to the detected result, thereby providing visual satisfaction to the user. 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 by the airflow detection module 230, so that excessive power of the battery 210 Prevent consumption.

First, the airflow detection module 230 configures a closed circuit so that power of the battery is supplied to the heater 250 and the LED 290 when airflow is detected inside the aerosol generating device. The airflow detection module 230 operates in a form having an LED 290, and the LED 290 temporarily forms a closed circuit with the battery 210 through the control of the airflow detection module 230, and the battery 210 It can be flashed by receiving power from. Although not shown in FIG. 4, a timer for determining the blinking start time of the LED 290 may be additionally provided, and may be set to blink according to the user's suction behavior.
