  • the ignition portion 15 may be coupled to the elastic support portion 21 and may be disposed to come in close contact with the upstream end of the smoking article 30 as the smoking article 30 is inserted. In this case, since the ignition portion 15 performs an ignition function while supporting the upstream end of the smoking article 30 together with the elastic support portion 21 , ignition stability may be further improved. Further, since ignition occurs in a state in which the ignition portion 15 is in close contact with the upstream end of the smoking article 30 , ignition performance may also be improved.
  • a portion of the ignition portion 15 that comes in close contact with the upstream end of the smoking article 30 may be formed in a sharp protruding shape (e.g., the shape of a needle).
  • the ignition portion 15 since the ignition portion 15 passes through the upstream end of the smoking article 30 as the smoking article 30 is inserted, the smoking article 30 may be supported more strongly at the time of ignition. Also, the support stability and ignition stability of the sidestream smoke removal device 1 may be further improved.
  • the ignition portion 15 may be disposed at a position different from a position of the elastic support portion 21 and may be implemented to be movable.

Accordingly, since there is no need to manufacture multiple sidestream smoke removal devices for smoking articles 30 of different lengths, manufacturing costs may be reduced, and the users' device purchasing costs may also be reduced.
  • FIG. 6 is an exemplary view for describing the sidestream smoke removal device 1 with improved support stability and ignition stability according to the second embodiment of the present disclosure.
  • the elastic support portion 21 may be disposed to be perpendicular to the longitudinal direction (direction of insertion) of the smoking article 30 . That is, when the smoking article 30 is inserted in the longitudinal direction of the sidestream smoke removal device 1 , the elastic support portion 21 may be disposed in a horizontal direction. Also, the ignition portion 15 may be coupled to the elastic support portion 21 and may come in close contact with the upstream end of the smoking article 30 as the smoking article 30 is inserted.

In this way, the number of support portions 22 , the arrangement form thereof, the shape thereof, etc. may be designed and implemented in various ways.
  • the support portion 22 When the support portion 22 supports a side surface of the smoking article 30 , support stability for the smoking article 30 may be continuously ensured even during smoking. Specifically, the elastic support portion 21 may support the smoking article 30 in an early stage of smoking, but a support ability thereof may weaken as smoking progresses. This is because the length of the smoking article 30 gradually shortens due to smoking. In this case, if the support portion 22 is disposed at an appropriate position, the smoking article 30 may be stably supported until the end of smoking. In addition, support stability at an early stage of smoking may also be further improved.
  • FIG. 7 illustrates an example in which the elastic support portion 21 is disposed in the longitudinal direction, but in some cases, the elastic support portion 21 may be omitted or may be disposed to be perpendicular to the longitudinal direction.

  • the control method is applicable to various types of sidestream smoke removal devices, but for convenience of understanding, description will be continued assuming that the control method is performed by the sidestream smoke removal device 1 illustrated in FIGS. 1 to 7 . Therefore, in the following description, when the subject of a specific operation is omitted, the specific operation may be understood as being performed by the controller 18 of the illustrated device 1 .
  • FIG. 8 is an exemplary flowchart showing a control method according to some embodiments of the present disclosure. However, this is only a preferred embodiment for achieving the objectives of the present disclosure, and, of course, some steps may be added or omitted as necessary.
  • the control method may begin by detecting the start of smoking (S 10 ). In this step, a method of detecting the start of smoking may vary.
  • the controller 18 may detect the start of smoking through a user input (e.g., an input on a button, etc.) operating the ignition portion 15 .
  • the controller 18 may recognize the start of smoking through a user input (e.g., an input on a button, etc.) requesting to start smoking and may operate the ignition portion 15 .
  • the controller 18 may detect the start of smoking in response to determining that a temperature measured by the temperature sensor 20 is higher than or equal to a reference value.
  • 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 S 20 in response to detecting the start of smoking, the controller 18 may open (e.g., partially or completely) the vent 111 such that outside air that enters through the vent 111 promotes 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 control 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 widen the vent 111 when puffs are performed and narrow the vent 111 when puffs are not performed. In this way, 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 that unpurified sidestream smoke leaks through the vent 111 while puffs are not performed may be alleviated. For reference, while puffs are performed, since sidestream smoke is not generated much and an incoming air flow is formed through the vent 111 , sidestream smoke may not leak 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 air flow may be concentrated toward the upstream end of the smoking article 30 such that combustion may be promoted.
  • 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 widen the vent 111 . In the opposite case, the controller 18 may narrow the vent 111 . 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 during puffs (that is, increase the rotational speed thereof in the reverse direction). 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 .
  • the controller 18 may recognize that a puff is generated. This recognition is based on a fact that 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 higher puff intensity based on the degree of temperature change being higher and determine the lower puff intensity based on the degree of temperature change being lower.
  • step S 30 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 the embodiment.
  • 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, when a puff number is a reference value or more, or when 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 pre-set.
  • smoking termination conditions may be pre-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 S 40 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 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 consumed. For example, when the smoking article 30 is completely combusted, 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 consumed may be determined on the basis of a puff number, the time elapsed after the start of smoking, the current smoking position (see FIG. 10 ), and the like.
