- the temperature sensor 20 may be disposed to measure the temperature near a downstream end of the smoking material portion. In this case, whether smoking has ended may be accurately determined using only the temperature sensor 20 without an additional monitoring module. This may be understood as using the fact that smoking usually ends upon complete combustion of the smoking material portion.
- the controller 18 may determine that smoking has ended when the temperature measured by the temperature sensor 20 is a reference value or more (e.g., when the current combustion position reaches the downstream end of the smoking material portion) or when the temperature measured by the temperature sensor 20 increases and then decreases to less than the reference value (e.g., when combustion power weakens at the downstream end of the smoking material portion).
- the ignition portion 15 may be disposed at a fixed position. Specifically, as illustrated in FIG. 1 and so on, the ignition portion 15 may be disposed to ignite the vicinity of the upstream end of the inserted smoking article 30. In this case, the structure of the sidestream smoke removal device 1 may be simplified, and thus a defect rate during manufacture may be minimized.

- FIG. 2 is an exemplary view for describing a first modification of the sidestream smoke removal device 1 according to some embodiments of the present disclosure.
- the sidestream smoke removal device 1 may further include a heating portion 40 disposed inside the housing 11 (that is, the smoking space).
- the heating portion 40 may heat the smoking space to remove a smell generated due to by-products of smoking (e.g., cigarette ash, sidestream smoke, etc.). In that way, the cleanliness of the smoking space can be improved, and a problem of causing discomfort to a user as a smell accumulated in the smoking space spreads to the outside can also be addressed.
- the operation, heating temperature, etc. of the heating portion 40 may be controlled by the controller 18. Meanwhile, the shape, operation time point, heating temperature (intensity), heating time, etc. of the heating portion 40 may be designed in various ways.
- the heating portion 40 may have an arrangement form and shape that can support a side surface of the smoking article 30 (e.g., an elongated shape illustrated in FIG. 2 , a shape similar to the shape of a support portion 22 illustrated in FIG. 5 ). In this case, the heating portion 40 may serve to support the smoking article 30 during smoking and may serve to remove a smell due to by-products of smoking after smoking.
- the heating portion 40 may heat the smoking space to a temperature in a range of about 50 °C to 200 °C or may heat the smoking space to a temperature in a range of about 70 °C to 180 °C, about 90 °C to 150 °C, or about 110 °C to 130 °C. It was confirmed that, within such numerical ranges, the smell due to by-products of smoking is effectively removed. Also, in some embodiments, the heating temperature of the heating portion 40 may be determined on the basis of a puff length or a puff intensity.

- the controller 18 may determine the heating temperature of the heating portion 40 as a lower value.
- the smoking time may be obtained by obtaining a difference between a smoking start time point and a smoking end time point, and a method of detecting the smoking start time point and the smoking end time point may vary.

- 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.

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 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 operate the exhaust fan 162 for a predetermined amount of time and then stop the operation or continuously operate the exhaust fan 162.

- 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.

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.

- step S50 the controller 18 may operate the heating portion 40 to heat the smoking space. 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.

The sidestream smoke removal device according to some embodiments of the present disclosure may include a housing in which a smoking space is formed, an article insertion portion which is disposed at one end of the housing and forms an opening for insertion of a smoking article into the smoking space, an ignition portion which is configured to ignite the smoking article inserted into the smoking space, a sidestream smoke processing portion which is configured to process sidestream smoke generated from the smoking article inserted into the smoking space, and a heating portion disposed inside the housing to heat the smoking space. The heating portion may heat the smoking space to remove a smell generated due to by-products of smoking, and accordingly, the cleanliness of the sidestream smoke removal device can be improved.
Description
- The present disclosure relates to a sidestream smoke removal device and a control method thereof, and more particularly, to a sidestream smoke removal device which removes a smell generated due to by-products of smoking that remain in the device, thus improving device cleanliness and user satisfaction, and a control method thereof.
- Generally, a sidestream smoke removal device is a type of smoking aid that has a sealed smoking space and a sidestream smoke remover provided therein. Users may insert a cigarette into the smoking space inside the sidestream smoke removal device and perform smoking to receive beneficial effects such as reduction of a smell on the user's hands and removal (purification) of a sidestream smoke.
- However, the by-products of smoking such as cigarette ash and sidestream smoke remain in the sealed smoking space even after smoking, and thus an unpleasant smell caused thereby lingers in the smoking space and inevitably lowers the cleanliness of the device. Further, a smell accumulated in the smoking space may spread to the outside when the device is opened and cause discomfort to the user.
- Some embodiments of the present disclosure are directed to providing a sidestream smoke removal device which removes a smell generated due to by-products of smoking that remain in the device, thus improving device cleanliness and user satisfaction, and a control method thereof. Some embodiments of the present disclosure are also directed to providing a sidestream smoke removal device with improved ease of use and safety and a control method thereof.
- Objectives of the present disclosure are not limited to the above-mentioned objectives, and other unmentioned objectives should be clearly understood by those of ordinary skill in the art to which the present disclosure pertains from the description below.
- A sidestream smoke removal device according to some embodiments of the present disclosure for achieving the above objectives may include a housing in which a smoking space is formed, an article insertion portion which is disposed at one end of the housing and forms an opening for insertion of a smoking article into the smoking space, an ignition portion which is configured to ignite the smoking article inserted into the smoking space, a sidestream smoke processing portion which is configured to process sidestream smoke generated from the smoking article inserted into the smoking space, and a heating portion disposed inside the housing to heat the smoking space.
- In some embodiments, a heating temperature of the heating portion may be in a range of 50 °C to 200 °C.
- In some embodiments, an operation time point of the heating portion may be determined on the basis of a smoking end time point.
- In some embodiments, an operation time point of the heating portion may be determined on the basis of a puff time point.
- In some embodiments, a heating temperature of the heating portion may be determined on the basis of smoking time.
- In some embodiments, the sidestream smoke removal device may further include a temperature sensor disposed to measure a temperature near a downstream end of a smoking material portion constituting the inserted smoking article and a controller configured to, on the basis of the temperature measured by the temperature sensor, determine whether smoking has ended.
- In some embodiments, a vent through which outside air enters may be formed in the housing.
- In some embodiments, a vent through which outside air enters may be formed in the housing, the sidestream smoke processing portion may include an exhaust fan configured to exhaust the sidestream smoke, and the sidestream smoke removal device may further include a controller configured to, in response to detection of an end of smoking, close the vent and stop an operation of the exhaust fan.
- According to some embodiments of the present disclosure, a heating portion configured to heat a smoking space inside a sidestream smoke removal device may be disposed. Through heating, the heating portion can remove an unpleasant smell generated due to by-products of smoking and thus improve cleanliness of the sidestream smoke removal device. Also, accordingly, a problem of causing discomfort to a user as a smell accumulated in the smoking space spreads to the outside can also be addressed.
- Also, information on smoking progress can be automatically provided to a user through a display. Accordingly, the user can directly check the smoking progress without operating the device, and thus ease of use and safety can be significantly improved.
- Also, the use of one or more temperature sensors disposed in the smoking space allows the smoking progress to be easily monitored without an additional monitoring module. For example, by measuring a change in temperature, a puff event can be easily monitored, and by comparing temperatures measured by a plurality of temperature sensors, the current combustion position of a smoking article can also be easily monitored.
- Also, a vent and an exhaust fan can be appropriately controlled according to smoking progress, and accordingly, a user's smoking satisfaction can be improved.
- In addition, an automatic extinguishing function can be performed upon detection of an end of smoking. Accordingly, the risk of fire or burns due to the user's carelessness can be minimized, and user convenience can be improved.
- The advantageous effects according to the technical spirit of the present disclosure are not limited to those mentioned above, and other unmentioned advantageous effects should be clearly understood by those of ordinary skill in the art from the description below.

- First, some terms used in various embodiments of the present disclosure will be clarified.
- In the following embodiments, "smoking article" may refer to any product that can be smoked or any product that can provide a smoking experience, regardless of whether the product is based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. For example, smoking articles may include products that can be smoked, such as a cigarette, a cigar, and a cigarillo.
- In the following embodiments, "smoking material" may refer to any material that generates smoke and/or aerosol or is used in smoking. For example, the smoking material may include a tobacco material. For example, the tobacco material may include pieces of tobacco leaves, tobacco stems, or materials obtained by processing the pieces of tobacco leaves or tobacco stems. As a more specific example, the tobacco material may include ground tobacco leaves, ground reconstituted tobacco, expanded shredded tobacco, expanded tobacco midribs, and reconstituted tobacco leaves. However, the tobacco material is not limited thereto.
- In the following embodiments, "upstream" or "upstream direction" may refer to a direction moving away from an oral region of a user, and "downstream" or "downstream direction" may refer to a direction approaching the oral region of the user. The terms "upstream" and "downstream" may be used to describe relative positions of components constituting a smoking article. For example, in a
smoking article 30 illustrated inFIG. 1 or the like, a filter portion is disposed downstream or in a downstream direction of a smoking material portion, and the smoking material portion is disposed upstream or in an upstream direction of the filter portion. In the following embodiments, "longitudinal direction" may refer to a direction corresponding to a longitudinal axis of a smoking article. - In the following embodiments, "puff" refers to inhalation by a user, and the inhalation may be a situation in which a user draws smoke into his or her oral cavity, nasal cavity, or lungs through the mouth or nose.
- Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
-
FIG. 1 is an exemplary view for describing a basic configuration of a sidestreamsmoke removal device 1 according to some embodiments of the present disclosure. In particular, the drawings such asFIG. 1 illustrate a state in which thesmoking article 30 is inserted into the sidestreamsmoke removal device 1. - As illustrated in
FIG. 1 , the sidestreamsmoke removal device 1 may include ahousing 11, anarticle insertion portion 12, aback cover 13, an insulatingportion 14, atemperature sensor 20, anignition portion 15, a sidestreamsmoke processing portion 16, amesh 17, adisplay 19, and acontroller 18. However, only the components relating to the embodiment of the present disclosure are illustrated inFIG. 1 . Therefore, those of ordinary skill in the art to which the present disclosure pertains should understand that the sidestreamsmoke removal device 1 may further include general-purpose components other than the components illustrated inFIG. 1 . For example, the sidestreamsmoke removal device 1 may further include a battery (not illustrated) configured to supply power to electrical components (e.g., thecontroller 18, thedisplay 19, etc.). Also, some of the components illustrated inFIG. 1 may not be essential components of the sidestreamsmoke removal device 1. That is, the sidestreamsmoke removal device 1 according to some other embodiments of the present disclosure may be implemented in a form in which some of the illustrated components are omitted. Hereinafter, each component of the sidestreamsmoke removal device 1 will be described. - The
housing 11 may form a smoking space inside the sidestreamsmoke removal device 1 and may form at least a portion of an exterior of the sidestreamsmoke removal device 1.FIG. 1 illustrates thehousing 11 as referring to a sidewall of the sidestreamsmoke removal device 1, but thehousing 11 may also refer to the entire exterior-forming structure including thearticle insertion portion 12, theback cover 13, and the insulatingportion 14. In order to ensure the durability of the sidestreamsmoke removal device 1 and minimize the risk of damage thereto, thehousing 11 may be made of a sturdy material. - In some embodiments, a
vent 111 may be formed in thehousing 11 to allow outside air to smoothly enter the smoking space. By allowing the outside air to enter during smoking, thevent 111 may promote combustion of thesmoking article 30, and accordingly, a smoking function of the sidestreamsmoke removal device 1 can be significantly improved.FIG. 1 illustrates an example in which asingle vent 111 is formed in thehousing 11, but the number ofvents 111 may also be plural. In addition, positions at which vents 111 are formed, sizes of the vents, intervals between the vents, etc. may also be designed in various ways. The opening/closing of thevent 111 and/or a degree of opening/closing thereof may be controlled by thecontroller 18. This will be described below with reference toFIG. 7 . - Next, the
article insertion portion 12 may be disposed at one end (e.g., an upper end) of thehousing 11 and form an opening for insertion of thesmoking article 30. A user may insert thesmoking article 30 into the smoking space inside the sidestreamsmoke removal device 1 through thearticle insertion portion 12. In order to block the heat inside the smoking space from being released to the outside, thearticle insertion portion 12 may be made of an insulating material. Also, in order to prevent shaking of the insertedsmoking article 30, thearticle insertion portion 12 may have a holder structure that can hold thesmoking article 30. - In some embodiments, the
article insertion portion 12 may have a structure in which it is possible to adjust the size of the opening. For example, thearticle insertion portion 12 may have a structure that allows the opening to be tightened or expanded through manual operation. As another example, thearticle insertion portion 12 may also be configured to automatically tighten the opening to fit thesmoking article 30. As a more specific example, thecontroller 18 may control the opening of thearticle insertion portion 12 to be tightened in response to insertion of thesmoking article 30 that is detected by a sensor or in response to reception of a user input (e.g., a push on a button). According to the present embodiment, since the size of the opening is adjusted to fit thesmoking article 30, shaking of thesmoking article 30 can be prevented, and support stability for thesmoking article 30 can be improved. Further, since it becomes possible to insert smoking articles of various sizes, usability of the sidestreamsmoke removal device 1 can also be improved. - The
smoking article 30 may consist of a filter portion which is disposed at a downstream portion and a smoking material portion which abuts an upstream end of the filter portion. However, a detailed structure of thesmoking article 30 may be modified in various ways. The filter portion may include a filter material that can filter smoke, and the smoking material portion may include a smoking material. Examples of thesmoking article 30 may include a combustion-type cigarette, but thesmoking article 30 is not limited thereto and may be any article which generates sidestream smoke during smoking. - Next, the
back cover 13 may be disposed at the other end (e.g., a lower end) of thehousing 11 and serve as a cover of the sidestreamsmoke removal device 1. A gas discharge path may be formed in theback cover 13 to allow sidestream smoke processed (purified) through the sidestreamsmoke processing portion 16 to be discharged to the outside. For example, a gas discharge path such a fine hole may be formed in theback cover 13. - Next, the insulating
portion 14 may be disposed on an outer surface of thehousing 11 and block the heat inside the smoking space from being released (transferred) to the outside. The insulatingportion 14 may be made of a material having low thermal conductivity and may serve to prevent the risk of burns due to internal heat when the user's body comes in contact with the sidestream smoke removal device 1 (e.g., when the user grips thedevice 1 for smoking). - Next, the
temperature sensor 20 may be disposed inside the smoking space and measure the temperature of thesmoking article 30 inserted into the smoking space. The number oftemperature sensors 20, the shape oftemperature sensors 20, positions at whichtemperature sensors 20 are disposed, intervals at whichtemperature sensors 20 are disposed, etc. may be designed in various ways and may vary according to embodiments. - In some embodiments, as illustrated, the
temperature sensor 20 may be disposed to measure the temperature near a downstream end of the smoking material portion. In this case, whether smoking has ended may be accurately determined using only thetemperature sensor 20 without an additional monitoring module. This may be understood as using the fact that smoking usually ends upon complete combustion of the smoking material portion. For example, thecontroller 18 may determine that smoking has ended when the temperature measured by thetemperature sensor 20 is a reference value or more (e.g., when the current combustion position reaches the downstream end of the smoking material portion) or when the temperature measured by thetemperature sensor 20 increases and then decreases to less than the reference value (e.g., when combustion power weakens at the downstream end of the smoking material portion). - Next, the
ignition portion 15 may be disposed inside the smoking space and ignite thesmoking article 30 inserted into the smoking space. Theignition portion 15 may be controlled by thecontroller 18 or may perform an ignition function due to manual operation by a user. The number ofignition portions 15, the shape ofignition portions 15, the arrangement form thereof, etc. may be designed in various ways and may vary according to embodiments. - In some embodiments, the
ignition portion 15 may be disposed at a fixed position. Specifically, as illustrated inFIG. 1 and so on, theignition portion 15 may be disposed to ignite the vicinity of the upstream end of the insertedsmoking article 30. In this case, the structure of the sidestreamsmoke removal device 1 may be simplified, and thus a defect rate during manufacture may be minimized. - In some other embodiments, the
ignition portion 15 may be designed and implemented to be movable. A specific implementation method may vary. For example, theignition portion 15 may be implemented to move in the longitudinal direction due to manual operation by a user or control by thecontroller 18. In some examples, thecontroller 18 may, in response to detecting the insertion of thesmoking article 30, move theignition portion 15 to the upstream end of thesmoking article 30. According to the present embodiment, since it becomes possible to universally apply the sidestreamsmoke removal device 1 to smoking articles of various lengths, the usability of the sidestreamsmoke removal device 1 can be significantly improved. - Next, the sidestream
smoke processing portion 16 may be disposed inside the smoking space and perform various processes for sidestream smoke generated from the insertedsmoking article 30. - For example, the sidestream
smoke processing portion 16 may be disposed between the insertedsmoking article 30 and theback cover 13 and perform a purification function for the sidestream smoke. Also, the sidestreamsmoke processing portion 16 may further perform an exhaust function that allows the purified sidestream smoke to be easily discharged to the outside. However, a detailed structure and an operation method of the sidestreamsmoke processing portion 16 may be designed in various ways and may vary according to embodiments. - In some embodiments, as illustrated, the sidestream
smoke processing portion 16 may be configured to include afilter structure 161 and anexhaust fan 162. Thefilter structure 161 may perform a purification function for the sidestream smoke, and theexhaust fan 162 may perform an exhaust function for the sidestream smoke. For example, theexhaust fan 162 may suction the sidestream smoke toward thefilter structure 161 through rotation and allow the sidestream smoke that has passed through thefilter structure 161 to be smoothly discharged to the outside. The operation of theexhaust fan 162 may be controlled by thecontroller 18. This will be described below with reference toFIG. 7 and so on. - Next, the
mesh 17 may be disposed between the sidestreamsmoke processing portion 16 and theback cover 13 and serve as a safety net. For example, themesh 17 may prevent a specific object (e.g., some pieces of thefilter structure 161, etc.) inside the smoking space from being detached toward theback cover 13. - Next, the
display 19 may be disposed on an outer surface of thehousing 11 to display various pieces of information according to control by thecontroller 18. For example, thedisplay 19 may display smoking progress information, device information, smoking history information, user information, and the like. Here, examples of the smoking progress information may include information on smoking progress (e.g., any information related to smoking progress such as the extent to which thesmoking article 30 is smoked, the current combustion position, the number of remaining puffs, smoking time, remaining smoking time, etc.) and puff information (e.g., any information related to puff events such as a puff number, a puff length, a puff interval, a puff intensity, whether puffs are performed, etc.), but the smoking progress information is not limited thereto. Examples of the device information may include information such as a power state, whether a failure has occurred, and a battery state (e.g., a battery level, whether charging is needed, etc.), but the device information is not limited thereto. The smoking history information may include the cumulative number of cigarettes smoked but is not limited thereto. - The
display 19 may include a visual display means such as a light emitting diode (LED) display and thus visually display the various pieces of information. However, a specific display means may vary. - Next, the
controller 18 may control the overall operation of the sidestreamsmoke removal device 1. For example, thecontroller 18 may control the operation of theexhaust fan 162, control the operation of thedisplay 19, and also control the operation of other components included in the sidestreamsmoke removal device 1. In addition, thecontroller 18 may determine smoking progress of thesmoking article 30 and may check a state of each of the components of the sidestreamsmoke removal device 1 to determine whether the sidestreamsmoke removal device 1 is in an operable state. A specific operation method of thecontroller 18 will be described in detail below with reference toFIGS. 7 to 10 . - The
controller 18 may be implemented with at least one processor. The processor may also be implemented with an array of a plurality of logic gates or implemented with a combination of a general-purpose microprocessor and a memory which stores a program that may be executed by the microprocessor. Also, those of ordinary skill in the art to which the present disclosure pertains should clearly understand that thecontroller 18 may also be implemented with other forms of hardware. -
FIG. 1 illustrates thecontroller 18 as being disposed outside thehousing 11 of the sidestreamsmoke removal device 1, but this is only for convenience of understanding, and the position at which thecontroller 18 is disposed may vary. For example, in order to prevent a failure due to external impact, thecontroller 18 may be disposed at a specific position inside thehousing 11. - Meanwhile, in some embodiments of the present disclosure, the sidestream
smoke removal device 1 may further include a module configured to provide aural and/or tactual outputs. For example, the sidestreamsmoke removal device 1 may further include a speaker, a vibration module, etc. In this case, thecontroller 18 may further use these modules to provide various pieces of information to the user. - The basic configuration of the sidestream
smoke removal device 1 according to some embodiments of the present disclosure has been described above with reference toFIG. 1 . Hereinafter, various modifications of the sidestreamsmoke removal device 1 will be described in detail with reference toFIGS. 2 to 6 . However, for clarity of the present disclosure, description of contents overlapping with the previous embodiment will be omitted. -
FIG. 2 is an exemplary view for describing a first modification of the sidestreamsmoke removal device 1 according to some embodiments of the present disclosure. - As illustrated in
FIG. 2 , the sidestreamsmoke removal device 1 according to the present modification may further include aheating portion 40 disposed inside the housing 11 (that is, the smoking space). - The
heating portion 40 may heat the smoking space to remove a smell generated due to by-products of smoking (e.g., cigarette ash, sidestream smoke, etc.). In that way, the cleanliness of the smoking space can be improved, and a problem of causing discomfort to a user as a smell accumulated in the smoking space spreads to the outside can also be addressed. The operation, heating temperature, etc. of theheating portion 40 may be controlled by thecontroller 18. Meanwhile, the shape, operation time point, heating temperature (intensity), heating time, etc. of theheating portion 40 may be designed in various ways. - In some embodiments, the
heating portion 40 may have an arrangement form and shape that can support a side surface of the smoking article 30 (e.g., an elongated shape illustrated inFIG. 2 , a shape similar to the shape of asupport portion 22 illustrated inFIG. 5 ). In this case, theheating portion 40 may serve to support thesmoking article 30 during smoking and may serve to remove a smell due to by-products of smoking after smoking. - Also, in some embodiments, the
heating portion 40 may heat the smoking space to a temperature in a range of about 50 °C to 200 °C or may heat the smoking space to a temperature in a range of about 70 °C to 180 °C, about 90 °C to 150 °C, or about 110 °C to 130 °C. It was confirmed that, within such numerical ranges, the smell due to by-products of smoking is effectively removed. Also, in some embodiments, the heating temperature of theheating portion 40 may be determined on the basis of a puff length or a puff intensity. For example, thecontroller 18 may determine the heating temperature of theheating portion 40 as a higher value with an increase in the puff length or puff intensity. This is because amounts of generated by-products of smoking (e.g., cigarette ash, sidestream smoke) increases with an increase in the puff length (or an increase in the puff intensity). In the opposite case, thecontroller 18 may determine the heating temperature of theheating portion 40 as a lower value. A method of measuring the puff length and puff intensity may vary. - Also, in some embodiments, the heating temperature of the
heating portion 40 may be determined on the basis of smoking time. For example, thecontroller 18 may determine the heating temperature of theheating portion 40 as a higher value with an increase in smoking time. This is because amounts of generated by-products of smoking (e.g., cigarette ash, sidestream smoke) increases with an increase in smoking time. In the opposite case, thecontroller 18 may determine the heating temperature of theheating portion 40 as a lower value. The smoking time may be obtained by obtaining a difference between a smoking start time point and a smoking end time point, and a method of detecting the smoking start time point and the smoking end time point may vary. For example, thecontroller 18 may use thetemperature sensor 20 to detect the smoking start time point and the smoking end time point. - Also, in some embodiments, the operation time point of the
heating portion 40 may be determined on the basis of a puff time point. For example, thecontroller 18 may operate theheating portion 40 every time a puff is detected. This is because by-products of smoking are generated every time a puff is performed. A method of detecting a puff may vary. For example, thecontroller 18 may use thetemperature sensor 20 to detect a puff, and this will be described below. - Also, in some embodiments, the operation time point of the
heating portion 40 may be determined on the basis of a smoking end time point. For example, thecontroller 18 may operate theheating portion 40 at a smoking end time point. Alternatively, thecontroller 18 may operate theheating portion 40 after a smoking end time point (e.g., operate theheating portion 40 one second after the smoking end time point) or operate theheating portion 40 before a predicted smoking end time point (e.g., operate theheating portion 40 one second before the predicted smoking end time point). A method of detecting or predicting an end of smoking may vary. For example, theheating portion 40 may use thetemperature sensor 20 to detect or predict an end of smoking or may predict an end of smoking on the basis of a puff number (e.g., predict that smoking will end upon a puff number reaching a certain value). - Also, in some embodiments, heating (operation) time of the
heating portion 40 may be determined on the basis of the smoking time. For example, thecontroller 18 may determine the heating time of theheating portion 40 as a larger value with an increase in the smoking time. This is because amounts of generated by-products of smoking (e.g., cigarette ash, sidestream smoke) increases with an increase in the smoking time. In the opposite case, thecontroller 18 may determine the heating time of theheating portion 40 as a smaller value. - Also, in some embodiments, the
heating portion 40 may operate on the basis of a combination of various embodiments described above. For example, thecontroller 18 may operate theheating portion 40 every time a puff is detected and may dynamically determine (adjust) the heating temperature of theheating portion 40 on the basis of a detected puff length or puff intensity. Alternatively, thecontroller 18 may operate theheating portion 40 after an end of smoking and may dynamically determine (adjust) the heating time or heating temperature of theheating portion 40 on the basis of the smoking time. -
FIG. 3 is an exemplary view for describing a second modification of the sidestreamsmoke removal device 1 according to some embodiments of the present disclosure. - As illustrated in
FIG. 3 , the sidestreamsmoke removal device 1 according to the present modification may include a plurality of temperature sensors 20-1 and 20-2 disposed at different positions inside the smoking space. For example, the plurality of temperature sensors 20-1 and 20-2 may be disposed in the longitudinal direction of thesmoking article 30. Alternatively, the plurality of temperature sensors (e.g., 20-1 and 20-2) may be disposed at positions facing each other.FIG. 3 illustrates an example in which the two temperature sensors 20-1 and 20-2 are disposed, but the number of temperature sensors may also be three or more. Here, the intervals at which the temperature sensors are disposed may be the same or different. When the plurality of temperature sensors (e.g., 20-1 and 20-2) are used, smoking progress (e.g., the extent to which thesmoking article 30 is smoked) may be more accurately monitored, and various pieces of monitoring information may be obtained. However, a specific monitoring method may vary according to the number of temperature sensors, positions at which the temperature sensors are disposed, and the like. - In some embodiments, the start of smoking may be detected (determined) through the temperature sensor (e.g., 20-2) disposed near the upstream end of the smoking material portion.
- For example, the
controller 18 may determine that smoking has started when the temperature measured by the temperature sensor (e.g., 20-2) is a reference value or more. - Also, in some embodiments, temperatures measured by the plurality of temperature sensors (e.g., 20-1 and 20-2) disposed in the longitudinal direction may be compared to determine the extent to which the
smoking article 30 is smoked (e.g., the current combustion position). This example will be described in more detail below with reference toFIGS. 8 and9 . - Also, in some embodiments, the plurality of temperature sensors (e.g., 20-1 and 20-2) may be disposed at positions facing each other with respect to the inserted
smoking article 30 or may be disposed in the circumferential direction of thesmoking article 30 inside the smoking space (for example, fourtemperature sensors 20 may be disposed at 90° intervals). In this case, temperatures measured by the plurality of temperature sensors (e.g., 20-1 and 20-2) may be compared to determine the extent to which thesmoking article 30 is tilted (shaken). For example, when a temperature measured by a specific temperature sensor is higher than a temperature measured by another temperature sensor, thecontroller 18 may determine that the insertedsmoking article 30 is tilted in a direction toward the specific temperature sensor. Alternatively, when temperatures measured by the plurality of temperature sensors (e.g., 20-1 and 20-2) fluctuate by a reference value or more, thecontroller 18 may determine that the insertedsmoking article 30 is shaking. -
FIG. 4 is an exemplary view for describing a third modification of the sidestreamsmoke removal device 1 according to some embodiments of the present disclosure. - As illustrated in
FIG. 4 , the sidestreamsmoke removal device 1 according to the present modification may further include anelastic support portion 21 coupled to theignition portion 15. Theelastic support portion 21 may be made of an elastic body that is able to stretch and contract and may serve to elastically support the upstream end of the insertedsmoking article 30. For example, as thesmoking article 30 is inserted, theignition portion 15 may come in close contact with the upstream end of thesmoking article 30, and theelastic support portion 21 may be contracted due to an insertion force, and thus thesmoking article 30 may be stably supported. Further, through stretching and contracting, theelastic support portion 21 may stably support smoking articles (e.g., 30) of various lengths (e.g., L1) and thus significantly improve the usability of the sidestreamsmoke removal device 1. - Meanwhile, in some embodiments, at least a portion of the
ignition portion 15 may have a sharp protruding shape (e.g., the shape of a needle) in a direction toward thearticle insertion portion 12. In this case, since theignition portion 15 passes through the upstream end of thesmoking article 30 as thesmoking article 30 is inserted, thesmoking article 30 may be supported more strongly at the time of ignition. Also, a problem that thesmoking article 30 is not ignited well due to shaking at the time of ignition can be significantly mitigated. -
FIG. 5 is an exemplary view for describing a fourth modification of the sidestreamsmoke removal device 1 according to some embodiments of the present disclosure. - As illustrated in
FIG. 5 , the sidestreamsmoke removal device 1 according to the present modification may further include thesupport portion 22 configured to support the side surface of thesmoking article 30 inserted into the smoking space. By supporting the side surface of thesmoking article 30, thesupport portion 22 may prevent thesmoking article 30 from shaking during smoking. - The number of
support portions 22, the arrangement form thereof, the shape thereof, etc. may be designed in various ways. For example, as illustrated, a plurality ofsupport portions 22 may be disposed to simultaneously support a side surface at a first portion and a side surface at a second portion of thesmoking article 30. Also, in order to support a specific portion of thesmoking article 30, a plurality ofsupport portions 22 may be disposed in the circumferential direction of the smoking article 30 (for example, foursupport portions 22 may be disposed at 90° intervals), or asingle support portion 22 formed in a ring shape may be disposed. -
FIG. 6 is an exemplary view for describing a fifth modification of the sidestreamsmoke removal device 1 according to some embodiments of the present disclosure. - As illustrated in
FIG. 6 , the sidestreamsmoke removal device 1 according to the present modification may further include a cuttingportion 23 disposed inside the smoking space. By cutting thesmoking article 30, which is undergoing combustion, to prevent further combustion, the cuttingportion 23 may provide a safe extinguishing function at a point in time desired by the user and can minimize the risk of burns that may occur due to carelessness of the user (e.g., the risk of burns due to carelessness when directly extinguishing the smoking article 30) and the risk of fire. However, an implementation method of the cuttingportion 23 may be designed in various ways. - In some embodiments, the cutting
portion 23 may be disposed at a fixed position and configured to cut a specific portion of the insertedsmoking article 30. For example, the cuttingportion 23 may be disposed to be fixed at a position where the cuttingportion 23 is able to cut between the filter portion and the smoking material portion. In this case, regardless of the current combustion (smoking) position of thesmoking article 30, a safe extinguishing function may be ensured, and the structure of the sidestreamsmoke removal device 1 may be simplified. - In some other embodiments, the cutting
portion 23 may be configured to be movable. For example, the cuttingportion 23 may be configured to move due to an external force (manual operation) by the user or may be configured to move due to control by thecontroller 18. As a more specific example, due to thecontroller 18, the cuttingportion 23 may automatically move to the vicinity of the current combustion (smoking) position of thesmoking article 30. Refer to description ofFIG. 9 below for description of a method in which thecontroller 18 determines the current combustion (smoking) position of thesmoking article 30. - Also, in some embodiments, the cutting
portion 23 may be operated due to a user pressing a push-type button (not illustrated) disposed on an outer surface of thehousing 11, twisting thehousing 11, or stretching or contracting thehousing 11 in the longitudinal direction. The cuttingportion 23 may have a structure mechanically linked to thehousing 11 in order to be operated due to the above actions, or thecontroller 18 may be implemented to operate the cuttingportion 23 in response to the above actions. - Various modifications of the sidestream
smoke removal device 1 according to some embodiments of the present disclosure have been described above with reference toFIGS. 2 to 6 . Hereinafter, a control method of the sidestream smoke removal device according to some embodiments of the present disclosure will be described with reference toFIG. 7 and so on. Each step of the control method which will be described below may be performed by the controller (e.g., 18) of the sidestream smoke removal device (e.g., 1). Also, each step of the control method may be implemented with one or more instructions executed by the controller. 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 sidestreamsmoke removal device 1 illustrated inFIGS. 1 to 6 . Therefore, in the following description, when the subject of a specific operation is omitted, the specific operation may be understood as being performed by thecontroller 18 of the illustrateddevice 1.FIG. 7 is an exemplary flowchart showing a control method of the sidestream smoke removal device according to some embodiments of the present disclosure. However, this is only an exemplary embodiment for achieving the objectives of the present disclosure, and, of course, some steps may be added or omitted as necessary. - As illustrated in
FIG. 7 , the control method may begin by detecting the start of smoking (S10). In this step, a method of detecting the start of smoking may vary. - In some embodiments, the
controller 18 may detect the start of smoking through a user input (e.g., an input on a button, etc.) operating theignition portion 15. Alternatively, thecontroller 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 theignition portion 15. - In some other embodiments, the
controller 18 may detect the start of smoking in response to determining that a temperature measured by thetemperature sensor 20 is a reference value or more. Here, for example, thetemperature sensor 20 may be disposed to measure the temperature near the upstream end of thesmoking article 30 inside the smoking space. - In step S20, in response to detecting the start of smoking, the
controller 18 may open (e.g., partially open or completely open) thevent 111. This is because outside air that enters through thevent 111 may promote combustion of thesmoking article 30. Also, thecontroller 18 may operate theexhaust fan 162. This is because, as theexhaust fan 162 operates, sidestream smoke generated during smoking may be smoothly exhausted. - Meanwhile, according to some embodiments of the present disclosure, the
controller 18 may perform control of thevent 111 and theexhaust fan 162 on the basis of puff events of the user during smoking. However, a specific control method thereof may vary. - In some examples, the
controller 18 may adjust a degree of opening/closing of thevent 111 on the basis of puff events. Specifically, thecontroller 18 may make thevent 111 more open when puffs are performed and make thevent 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 thesmoking article 30 may be further promoted. Also, a problem in that unpurified sidestream smoke leaks through thevent 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 thevent 111, leaking of sidestream smoke may not occur even when thevent 111 is opened. - In some other examples, the
controller 18 may operate (rotate) theexhaust fan 162 in a reverse direction while puffs are performed and may operate (rotate) theexhaust fan 162 in a forward direction while puffs are not performed. Here, the forward direction may refer to a rotational direction that causes sidestream smoke to be suctioned toward thefilter structure 161, and the reverse direction may refer to the opposite rotational direction. In this case, while puffs are performed, an airflow may be concentrated toward the upstream end of thesmoking article 30 and combustion may be promoted, and while puffs are not performed, sidestream smoke may be suctioned toward thefilter structure 161 and smoothly exhausted. - In still some other examples, the
controller 18 may adjust the degree of opening/closing of thevent 111 and/or the rotational speed of theexhaust 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, thecontroller 18 may make thevent 111 more open. In the opposite case, thecontroller 18 may make thevent 111 less open. This is because the puff intensity is likely to increase when combustion of thesmoking article 30 is not smoothly performed. Alternatively, in the case in which the puff intensity increases, the puff length increases, or the puff interval decreases, thecontroller 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, thecontroller 18 may decrease the rotational speed of theexhaust fan 162. - In yet some other examples, the
controller 18 may perform control on the basis of combinations of the above-described examples. - In the previous embodiments, a method in which the
controller 18 detects a puff may vary. For example, thecontroller 18 may detect a puff on the basis of a change in temperature measured by thetemperature sensor 20. Specifically, when a degree of temperature change is a reference value or more (e.g., when a combustion temperature of thesmoking article 30 instantaneously increases), thecontroller 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 thesmoking article 30 while puffs are generated. Also, thecontroller 18 may determine a puff intensity on the basis of a degree of temperature change. For example, thecontroller 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. - In step S30, the
controller 18 may detect the end of smoking. In this step, thecontroller 18 may detect the end of smoking using various methods, and the method may vary according to embodiments. - In some embodiments, the
controller 18 may detect the end of smoking on the basis of a temperature measured by thetemperature sensor 20. Here, for example, thetemperature sensor 20 may be disposed near the downstream end of the smoking material portion of thesmoking article 30. For example, when the temperature measured by thetemperature sensor 20 is a reference value or more or the measured temperature increases and then decreases, thecontroller 18 may determine that smoking has ended. - In some other embodiments, 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, thecontroller 18 may determine that smoking has ended. - In still some other embodiments, smoking termination conditions may be set. For example, 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. - In step S40, in response to detecting the end of smoking, the
controller 18 may perform an automatic extinguishing function. In this step, a method in which thecontroller 18 performs the automatic extinguishing function may vary. - In some embodiments, the
controller 18 may close thevent 111 and stop operation of theexhaust fan 162. In this case, since outside air stops entering due to closing of thevent 111, thesmoking article 30 may be naturally extinguished due to lack of oxygen. - In some other embodiments, the
controller 18 may close thevent 111 and operate theexhaust fan 162 for a predetermined amount of time and then stop the operation or continuously operate theexhaust fan 162. In this case, since outside air stops entering due to closing of thevent 111, and inside air is exhausted to the outside through theexhaust fan 162, thesmoking article 30 may be naturally extinguished. - In still some other embodiments, the
controller 18 may perform the automatic extinguishing function by operating the cuttingportion 23. - In yet some other embodiments, the
controller 18 may perform the automatic extinguishing function on the basis of combinations of the above-described embodiments. For example, thecontroller 18 may perform the automatic extinguishing function through a first extinguishing process of closing thevent 111 and stopping operation of theexhaust fan 162 and a second extinguishing process of cutting the insertedsmoking article 30 through the cuttingportion 23. Here, the first extinguishing process and the second extinguishing process may be performed in any order. - Meanwhile, according to some embodiments of the present disclosure, in response to detecting the end of smoking, the
controller 18 may operate theexhaust fan 162 in the forward direction (that is, the suctioning direction) for a predetermined amount of time. In this case, since by-products of smoking such as cigarette ash gather near thefilter structure 161 due to theexhaust fan 162, the inside of the sidestreamsmoke removal device 1 can be cleaned more easily. In some examples, thecontroller 18 may also adjust the rotational speed of theexhaust fan 162 on the basis of the extent to which thesmoking article 30 is burned. For example, when thesmoking article 30 is completely burned, since the amount of by-products is large, thecontroller 18 may rotate theexhaust fan 162 at a higher speed. In the opposite case, thecontroller 18 may rotate theexhaust fan 162 at a lower speed. The extent to which thesmoking 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 (seeFIG. 9 ), and the like. - In step S50, the
controller 18 may operate theheating portion 40 to heat the smoking space. 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, thecontroller 18 may operate theheating 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, thecontroller 18 may operate theheating portion 40 every time a puff is detected. - The operation time point, heating temperature, heating time, etc. of the
heating portion 40 may be designed in various ways, and description thereof will be omitted to avoid repeated description. - Meanwhile,
FIG. 7 illustrates an example in which step S40 and step S50 are performed in that order, but this is only for providing convenience of understanding, and step S40 and step S50 may be performed in an order different from the illustrated order or may be simultaneously performed. - The control method of the sidestream smoke removal device according to some embodiments of the present disclosure has been described above with reference to
FIG. 7 . According to the above-described method, since thevent 111 and theexhaust fan 162 may be appropriately controlled according to smoking progress, a user's satisfaction with the device can be improved. Also, since the automatic extinguishing function is performed upon the end of smoking, the risk of fire and burns due to the user's carelessness can be minimized. Further, by effectively removing a smell remaining in the smoking space through heating, the cleanliness of the sidestreamsmoke removal device 1 can be improved. - Hereinafter, a control method of the sidestream smoke removal device according to some other embodiments of the present disclosure will be described with reference to
FIG. 8 . However, for clarity of the present disclosure, description of contents overlapping with those related to the control method illustrated inFIG. 7 will be omitted. -
FIG. 8 is an exemplary flowchart showing the control method of the sidestream smoke removal device according to some other embodiments of the present disclosure. However, this is only an exemplary embodiment for achieving the objectives of the present disclosure, and, of course, some steps may be added or omitted as necessary. - As illustrated in
FIG. 8 , the control method may begin by detecting the start of smoking (S110). In this step, thecontroller 18 may display an indicator indicating the start of smoking on thedisplay 19. For additional description of this step, refer to step S10 described above with reference toFIG. 7 . - In step S120, the
controller 18 may monitor smoking progress. Here, smoking progress may include any situation related to smoking such as the extent to which thesmoking article 30 is smoked, puff events, and the like. - In some embodiments, the
controller 18 may compare temperatures measured by a plurality oftemperature sensors 20 disposed at different positions to accurately determine the extent to which thesmoking article 30 is smoked (or the current smoking (combustion) position thereof). Specifically, let's assume that, as illustrated inFIG. 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 sidestreamsmoke removal device 1. Then, thecontroller 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 thesmoking article 30 and the extent to which thesmoking article 30 is smoked. For example, in a case in which the temperature measured by the first temperature sensor 20-1 is the lowest, the temperature measured by the second temperature sensor 20-2 is lower than the temperature measured by the third temperature sensor 20-3, and the temperature measured by the third temperature sensor 20-3 is the highest, thecontroller 18 may determine that the current combustion (smoking) position of thesmoking article 30 is between the second temperature sensor 20-2 and the third temperature sensor 20-3 and closer to the third temperature sensor 20-3. Here, thecontroller 18 may determine that the larger the temperature difference between the second temperature sensor 20-2 and the third temperature sensor 20-3, the closer the current combustion (smoking) position of thesmoking article 30 is to the third temperature sensor 20-3. - In step S130, the
controller 18 may display monitoring information through thedisplay 19. However, types of monitoring information and a specific display method therefor may be designed in various ways. - In some embodiments, the
controller 18 may display, through thedisplay 19, information related to the extent to which thesmoking article 30 is smoked. For example, thecontroller 18 may display an indicator (e.g., a cigarette-shaped object) indicating the smoking article 30 (or the extent to which thesmoking article 30 is smoked) and may control thedisplay 19 to reduce the length of the indicator as smoking is performed. As another example, as illustrated inFIG. 10 , thecontroller 18 may display, through thedisplay 19, a display area (e.g., LED lighting areas/sections) indicating the extent to which thesmoking article 30 is smoked and may control thedisplay 19 to change the size of the display area (e.g., the number of LED lighting areas/sections) as smoking is performed. Here, the size of the display area may increase or decrease as smoking is performed. - In some other embodiments, the
controller 18 may display information related to puff events through thedisplay 19. For example, thecontroller 18 may display a puff number. As another example, thecontroller 18 may, in response to detecting puffs, display an indicator indicating that puffs are being performed. - In step S140, the
controller 18 may detect the end of smoking. In this step, thecontroller 18 may display an indicator indicating the end of smoking through thedisplay 19. For additional description of this step, refer to step S30 described above with reference toFIG. 7 . - Meanwhile, the
controller 18 may perform the automatic extinguishing function upon detecting the end of smoking, may display an indicator indicating automatic extinguishing through thedisplay 19, and may also display an indicator indicating the completion of automatic extinguishing upon completion of automatic extinguishing. - The control method of the sidestream smoke removal device according to some other embodiments of the present disclosure has been described above with reference to
FIGS. 8 to 10 . According to the above-described method, smoking progress information may be displayed through thedisplay 19. Accordingly, since the user may check smoking progress in real time through thedisplay 19, the ease of use and safety can be significantly improved. - The technical spirit of the present disclosure described above with reference to
FIGS. 1 to 10 may at least partially be implemented with computer-readable code on computer-readable recording media. Examples of the computer-readable recording media may include removable recording media (a compact disc (CD), a digital versatile disc (DVD), a Blu-Ray disk, a universal serial bus (USB) storage device, or a removable hard disk) or non-removable recording media (a read-only memory (ROM), a random access memory (RAM), or a built-in hard disk). Computer programs recorded in the computer-readable recording media may be sent to other computing devices through a network, such as the Internet, and installed in the other computing devices so as to be used in the other computing devices. - All the components constituting the embodiments of the present disclosure have been described above as being combined into one body or being operated in combination, but the technical spirit of the present disclosure is not necessarily limited to the embodiments. That is, any one or more of the components may be selectively operated in combination within the intended scope of the present disclosure.
