  • the temperature sensor 20 may be disposed to measure the temperature near the upstream end of the smoking article 30 inside the smoking space.
  • step S20 in response to detecting the start of smoking, the controller 18 may open (e.g., partially open or completely open) the vent 111. This is because outside air that enters through the vent 111 may promote combustion of the smoking article 30. Also, the controller 18 may operate the exhaust fan 162. This is because, as the exhaust fan 162 operates, sidestream smoke generated during smoking may be smoothly exhausted.
  • the controller 18 may perform control of the vent 111 and the exhaust fan 162 on the basis of puff events of the user during smoking.
  • a specific control method thereof may vary.
  • the controller 18 may adjust a degree of opening/closing of the vent 111 on the basis of puff events. Specifically, the controller 18 may make the vent 111 more open when puffs are performed and make the vent 111 less open when puffs are not performed. In this case, outside air may more smoothly enter while puffs are performed, and thus combustion of the smoking article 30 may be further promoted. Also, a problem in that unpurified sidestream smoke leaks through the vent 111 while puffs are not performed may be mitigated. For reference, while puffs are performed, since sidestream smoke is not generated much and an air flow path through which gas enters is formed through the vent 111, leaking of sidestream smoke may not occur even when the vent 111 is opened.
  • the controller 18 may operate (rotate) the exhaust fan 162 in a reverse direction while puffs are performed and may operate (rotate) the exhaust fan 162 in a forward direction while puffs are not performed.
  • the forward direction may refer to a rotational direction that causes sidestream smoke to be suctioned toward the filter structure 161
  • the reverse direction may refer to the opposite rotational direction.
  • an airflow may be concentrated toward the upstream end of the smoking article 30 and combustion may be promoted, and while puffs are not performed, sidestream smoke may be suctioned toward the filter structure 161 and smoothly exhausted.
  • the controller 18 may adjust the degree of opening/closing of the vent 111 and/or the rotational speed of the exhaust fan 162 on the basis of information on puff events (e.g., a puff intensity, a puff interval, a puff length, etc.). For example, in a case in which the puff intensity increases, the puff length increases, or the puff interval decreases, the controller 18 may make the vent 111 more open. In the opposite case, the controller 18 may make the vent 111 less open. This is because the puff intensity is likely to increase when combustion of the smoking article 30 is not smoothly performed.
  • a puff intensity e.g., a puff intensity, a puff interval, a puff length, etc.
  • the controller 18 may increase the rotational speed of the exhaust fan 162 (that is, the rotational speed thereof in the reverse direction) while puffs are performed. In the opposite case, the controller 18 may decrease the rotational speed of the exhaust fan 162.
  • controller 18 may perform control on the basis of combinations of the above-described examples.
  • a method in which the controller 18 detects a puff may vary.
  • the controller 18 may detect a puff on the basis of a change in temperature measured by the temperature sensor 20.
  • a degree of temperature change is a reference value or more (e.g., when a combustion temperature of the smoking article 30 instantaneously increases)
  • the controller 18 may recognize that a puff is generated. This may be understood as using a phenomenon in which combustion is accelerated at the upstream end of the smoking article 30 while puffs are generated.
  • the controller 18 may determine a puff intensity on the basis of a degree of temperature change. For example, the controller 18 may determine the puff intensity to be higher as the degree of temperature change is higher and determine the puff intensity to be lower as the degree of temperature change is lower.
  • step S30 the controller 18 may detect the end of smoking.
  • the controller 18 may detect the end of smoking using various methods, and the method may vary according to embodiments.
  • the controller 18 may detect the end of smoking on the basis of a temperature measured by the temperature sensor 20.
  • the temperature sensor 20 may be disposed near the downstream end of the smoking material portion of the smoking article 30.
  • the controller 18 may determine that smoking has ended.
  • the controller 18 may detect the end of smoking on the basis of puff events, the time elapsed after the start of smoking, and the like. For example, when a predetermined amount of time has elapsed after the start of smoking, a puff number is a reference value or more, or a puff has not been detected for a predetermined amount of time or more after a previous puff, the controller 18 may determine that smoking has ended.
  • smoking termination conditions may be set.
  • smoking termination conditions may be set on the basis of a puff number, the time elapsed after the start of smoking, and the like. In this case, in response to predetermined smoking termination conditions being satisfied, the controller 18 may determine to end smoking.
  • step S40 in response to detecting the end of smoking, the controller 18 may perform an automatic extinguishing function.
  • a method in which the controller 18 performs the automatic extinguishing function may vary.
  • the controller 18 may close the vent 111 and stop operation of the exhaust fan 162. In this case, since outside air stops entering due to closing of the vent 111, the smoking article 30 may be naturally extinguished due to lack of oxygen.
  • the controller 18 may close the vent 111 and operate the exhaust fan 162 for a predetermined amount of time and then stop the operation or continuously operate the exhaust fan 162. In this case, since outside air stops entering due to closing of the vent 111, and inside air is exhausted to the outside through the exhaust fan 162, the smoking article 30 may be naturally extinguished.
  • the controller 18 may perform the automatic extinguishing function by operating the cutting portion 23.
  • the controller 18 may perform the automatic extinguishing function on the basis of combinations of the above-described embodiments.
  • the controller 18 may perform the automatic extinguishing function through a first extinguishing process of closing the vent 111 and stopping operation of the exhaust fan 162 and a second extinguishing process of cutting the inserted smoking article 30 through the cutting portion 23.
  • the first extinguishing process and the second extinguishing process may be performed in any order.
  • the controller 18 in response to detecting the end of smoking, may operate the exhaust fan 162 in the forward direction (that is, the suctioning direction) for a predetermined amount of time.
  • the controller 18 may also adjust the rotational speed of the exhaust fan 162 on the basis of the extent to which the smoking article 30 is burned. For example, when the smoking article 30 is completely burned, since the amount of by-products is large, the controller 18 may rotate the exhaust fan 162 at a higher speed.
  • the controller 18 may rotate the exhaust fan 162 at a lower speed.
  • the extent to which the smoking article 30 is burned may be determined on the basis of a puff number, the time elapsed after the start of smoking, the current combustion (smoking) position (see FIG. 9 ), and the like.

In that way, a smell generated due to by-products of smoking can be effectively removed from inside the smoking space. However, in some cases, the controller 18 may operate the heating portion 40 periodically or non-periodically even during smoking. For example, in order to rapidly remove a smell of by-products of smoking that is generated due to puffs, the controller 18 may operate the heating portion 40 every time a puff is detected.

Specifically, let's assume that, as illustrated in FIG. 9 , a plurality of temperature sensors 20-1, 20-2, and 20-3 are disposed in the longitudinal direction in the smoking space inside the sidestream smoke removal device 1. Then, the controller 18 may compare temperatures measured by a first temperature sensor 20-1, a second temperature sensor 20-2, and a third temperature sensor 20-3 to determine the current combustion (smoking) position of the smoking article 30 and the extent to which the smoking article 30 is smoked.
