Description

[Technical field]

[0001] The present disclosure relates to a sidestream smoke removal device and a control method thereof, and more particularly to a sidestream smoke removal device and a control method thereof that can improve device cleanliness and user satisfaction by removing odors generated by smoking by-products remaining inside the device. [Background technology]

[0002] A sidestream smoke removal device is a type of smoking auxiliary mechanism that typically includes a sealed smoking space and a sidestream smoke removal means inside. A user inserts a cigarette into the smoking space inside the sidestream smoke removal device and smokes, thereby providing beneficial effects such as reduction of hand odor and removal (purification) of sidestream smoke.

[0003] However, since smoking by-products such as cigarette ash and sidestream smoke remain in the enclosed smoking space even after smoking, the unpleasant odor generated by the smoking remains in the smoking space and inevitably reduces the cleanliness of the device. In addition, the odor accumulated in the smoking space may spread to the outside when the device is opened, causing discomfort to the user. Summary of the Invention [Problem to be solved by the invention]

[0004] The technical problem to be solved through some embodiments of the present disclosure is to provide a sidestream smoke removal device and a control method for the device that can improve device cleanliness and user satisfaction by removing odors generated by smoking by-products remaining inside the device.

[0005] Another technical problem to be solved through some embodiments of the present disclosure is to provide a sidestream smoke removal device and a control method thereof that are convenient to use and safer.

[0006] The technical problems of the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person skilled in the art of the present disclosure from the following description. [Means for solving the problem]

[0007] In order to solve the above technical problems, a sidestream smoke removal device according to several embodiments of the present disclosure includes a housing having a smoking space formed therein, an article insertion section located at one end of the housing and forming an opening for inserting a smoking article into the smoking space, an ignition section for igniting the smoking article inserted into the smoking space, a sidestream smoke treatment section for treating sidestream smoke generated by the smoking article inserted into the smoking space, and a heating section located inside the housing for heating the smoking space.

[0008] In some embodiments, the heating temperature of the heating unit may be 50°C to 200°C.

[0009] In some embodiments, the time when the heating element is activated may be determined based on the end of smoking.

[0010] In some embodiments, the activation time of the heating element may be determined based on the puff time.

[0011] In some embodiments, the heating temperature of the heating portion may be determined based on smoking time.

[0012] In some embodiments, the sidestream smoke removal device may further include a temperature sensor arranged to measure the temperature near the downstream end of the smoking material portion constituting the inserted smoking article, and a control unit that determines whether smoking has ended based on the temperature measured by the temperature sensor.

[0013] In some embodiments, the housing may be formed with a vent hole to allow outside air to enter.

[0014] In some embodiments, the housing is formed with a vent hole through which outside air flows in, and the sidestream smoke treatment device includes an exhaust fan that exhausts the sidestream smoke, and the sidestream smoke removal device may further include a control unit that closes the vent hole and stops operation of the exhaust fan in response to detecting the end of smoking. Effect of the Invention

[0015] According to some embodiments of the present disclosure, a heating unit for heating the smoking space may be disposed inside the device. The heating unit may improve the cleanliness of the sidestream smoke removal device by removing unpleasant odors generated by smoking by-products through heating. In addition, this may solve the problem of odors accumulated in the smoking space diffusing to the outside, causing discomfort to the user.

[0016] In addition, information regarding the progress of smoking can be automatically provided to the user through the display unit, allowing the user to directly check the progress of smoking without operating the device, greatly improving convenience and safety of use.

[0017] In addition, by utilizing one or more temperature sensors disposed within the smoking space, the progress of smoking can be easily monitored without an additional monitoring module. For example, a puff event can be easily monitored by measuring a change in temperature, and the current burning position of the smoking article can be easily monitored by comparing temperatures measured by multiple temperature sensors.

[0018] In addition, the vent hole and the exhaust fan can be appropriately controlled according to the progress of smoking, which can improve the user's smoking satisfaction.

[0019] In addition, an automatic extinguishing function can be performed when the end of smoking is detected, thereby minimizing the risk of fire and burns caused by the user's carelessness and improving user convenience.

[0020] The effects of the technical ideas of the present disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the following description. [Brief description of the drawings]

[0033] Various embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings.

[0034] Fig. 1 is an exemplary diagram for explaining the basic configuration of a sidestream smoke removal device 1 according to some embodiments of the present disclosure. In particular, Fig. 1 and other drawings illustrate a state in which a smoking article 30 is inserted.

[0035] As shown in Fig. 1, the sidestream smoke removal device 1 may include a housing 11, an article insertion section 12, a back cover 13, a heat insulating section 14, a temperature sensor 20, an ignition section 15, a sidestream smoke treatment section 16, a mesh net 17, a display section 19, and a control section 18. However, Fig. 1 illustrates only components related to the embodiment of the present disclosure. Therefore, a person skilled in the art to which the present disclosure belongs will understand that other general components may be further included in addition to the components illustrated in Fig. 1. For example, the sidestream smoke removal device 1 may further include a battery (not shown) for supplying power to electrical components (e.g., the control section 18, the display section 19, etc.).

[0036] 1 may not be essential components of the sidestream smoke elimination device 1. In other words, the sidestream smoke elimination device 1 according to some other embodiments of the present disclosure may be embodied in a form in which some of the illustrated components are omitted. Hereinafter, each component of the sidestream smoke elimination device 1 will be described.

[0037] The housing 11 can form a smoking space inside the sidestream smoke removal device 1, and can form at least a part of the exterior of the sidestream smoke removal device 1. Although Fig. 1 illustrates the housing 11 as referring to the side wall of the sidestream smoke removal device 1, the housing 11 may refer to all of the exterior forming structures including the article insertion section 12, the back cover 13, and the heat insulating section 14. In order to ensure the durability of the sidestream smoke removal device 1 and minimize the risk of damage, the housing 11 is preferably formed of a sturdy material.

[0038] In some embodiments, the housing 11 may be formed with a vent hole 111 to allow outside air to smoothly flow into the smoking space. The vent hole 111 allows outside air to flow in during smoking, thereby promoting the combustion of the smoking article 30, and thus the smoking function of the sidestream smoke removal device 1 may be significantly improved. Although FIG. 1 illustrates an example in which one vent hole 111 is formed in the housing 11, the number of vent holes 111 may be multiple. In addition, the formation position, size, interval, etc. of the vent hole 111 may be variously designed. Whether or not the vent hole 111 is opened and / or closed and / or the degree of opening and closing may be controlled by the control unit 18, which will be described later with reference to FIG. 7.

[0039] Next, the article insertion part 12 is located at one end (e.g., the upper end) of the housing 11 and can form an opening for inserting the smoking article 30. A user can insert the smoking article 30 into the smoking space in the sidestream smoke removal device 1 through the article insertion part 12. In order to prevent heat inside the smoking space from being released to the outside, the article insertion part 12 is preferably made of a heat insulating material. Also, in order to prevent the inserted smoking article 30 from shaking, the article insertion part 12 preferably has a holder structure that can hold the smoking article 30.

[0040] In some embodiments, the article insertion part 12 may be formed with a structure that allows the size of the opening to be adjusted. For example, the article insertion part 12 may be formed with a structure that allows the opening to be tightened or expanded through manual operation. As another example, the article insertion part 12 may be configured to automatically tighten the opening to fit the smoking article 30. As a more specific example, the control unit 18 may control the article insertion part 12 to tighten the opening in response to sensing the insertion of the smoking article 30 through a sensor or receiving a user input (e.g., a button push). According to this embodiment, the size of the opening is adjusted to fit the smoking article 30, thereby preventing the smoking article 30 from shaking and improving the support stability. Furthermore, since smoking articles of various sizes can be inserted, the usability of the sidestream smoke removal device 1 may be improved.

[0041] The smoking article 30 may be comprised of a downstream filter section and a smoking material section abutting the upstream end of the filter section. However, the detailed structure of the smoking article 30 may vary. The filter section may include a filter material capable of filtering smoke, and the smoking material section may include smoking material. An example of the smoking article 30 includes, but is not limited to, a combustion cigarette, and the smoking article 30 may include any article that generates sidestream smoke when smoked.

[0042] Next, the back cover 13 is located at the other end (e.g., the lower end) of the housing 11 and can function as a cover of the sidestream smoke removal device 1. The back cover 13 may have a gas exhaust passage so that the sidestream smoke treated (purified) through the sidestream smoke treatment unit 16 can be exhausted to the outside. For example, the back cover 13 may have a gas exhaust passage such as a fine hole.

[0043] Next, the heat insulating part 14 is disposed on the outer surface of the housing 11 to prevent heat inside the smoking space from being released (transmitted) to the outside. The heat insulating part 14 may be made of a material with low thermal conductivity and may play a role in preventing the risk of burns caused by internal heat when the user's body comes into contact with the sidestream smoke removal device 1 (for example, when holding the device 1 for smoking).

[0044] Next, the temperature sensor 20 is disposed in the smoking space to measure the temperature of the smoking article 30 inserted in the smoking space. The number, shape, arrangement position, arrangement interval, etc. of the temperature sensor 20 may be variously designed and may vary depending on the embodiment.

[0045] In some embodiments, as shown, the temperature sensor 20 may be positioned to measure the temperature near the downstream end of the smoking material portion. In such a case, the end of smoking may be accurately determined using only the temperature sensor 20 without an additional monitoring module, which may be understood as utilizing the fact that smoking typically ends when the smoking material portion is completely burned. For example, the control unit 18 may determine that smoking has ended when the temperature measured by the temperature sensor 20 is equal to or greater than a reference value (e.g., when the current burning position has reached the downstream end of the smoking material portion) or when the temperature measured by the temperature sensor 20 increases and then decreases below the reference value (e.g., when the burning power at the downstream end of the smoking material portion weakens).

[0046] Next, the ignition unit 15 is disposed in the smoking space and can ignite the smoking article 30 inserted in the smoking space. The ignition unit 15 can be controlled by the control unit 18, and can provide an ignition function through manual operation by a user. The number, shape, arrangement, etc. of the ignition unit 15 can be designed in various ways, and this can vary depending on the embodiment.

[0047] In some embodiments, the ignition unit 15 may be disposed at a fixed position. Specifically, as shown in Fig. 1, the ignition unit 15 may be disposed so as to be capable of igniting the vicinity of the upstream end of the inserted smoking article 30. In such a case, the structure of the sidestream smoke removal device 1 may be simplified, and the defective rate during manufacturing may be minimized.

[0048] In some other embodiments, the ignition unit 15 may be designed and embodied to be movable. Any specific implementation method may be used. For example, the ignition unit 15 may be embodied to move in the length direction by manual operation by a user or by control of the control unit 18. In some examples, the control unit 18 may move the ignition unit 15 to the upstream end of the smoking article 30 in response to detecting the insertion of the smoking article 30. According to this embodiment, the sidestream smoke removal device 1 can be universally applied to smoking articles of various lengths, and the usability of the sidestream smoke removal device 1 can be greatly improved.

[0049] Next, the sidestream smoke treatment device 16 is disposed in the smoking space and can perform various treatments on the sidestream smoke generated by the inserted smoking article 30. For example, the sidestream smoke treatment device 16 can be located between the inserted smoking article 30 and the back cover 13 and can perform a purification function on the sidestream smoke. The sidestream smoke treatment device 16 can also perform an exhaust function to efficiently exhaust the purified sidestream smoke to the outside. However, the detailed structure and operation method of the sidestream smoke treatment device 16 can be designed in various ways and can be changed depending on the embodiment.

[0050] In some embodiments, as shown in the drawings, the sidestream smoke treatment device 16 may be configured to include a filter structure 161 and an exhaust fan 162. The filter structure 161 may perform a purification function for sidestream smoke, and the exhaust fan 162 may perform an exhaust function for the sidestream smoke. For example, the exhaust fan 162 may rotate to draw the sidestream smoke toward the filter structure 161, so that the sidestream smoke that has passed through the filter structure 161 may be smoothly exhausted to the outside. The operation of the exhaust fan 162 may be controlled by the control unit 18, which will be described later with reference to figures such as FIG. 7.

[0051] Next, the mesh net 17 can be disposed between the sidestream smoke treatment device 16 and the back cover 13 to serve as a safety net. For example, the mesh net 17 can prevent a specific object (e.g., some small pieces of the filter structure 161) inside the smoking space from escaping toward the back cover 13.

[0052] Next, the display unit 19 is located on the outer surface of the housing 11 and can display various information under the control of the control unit 18. For example, the display unit 19 can display information on the progress of smoking, device information, smoking history information, user information, etc. Here, the information on the progress of smoking can include, but is not limited to, smoking progress information (e.g., all information related to smoking progress, such as the degree of smoking progress, current burning position, remaining number of puffs, smoking time, remaining smoking time, etc.), puff information (e.g., all information related to puff events, such as number of puffs, puff length, puff interval, puff strength, whether or not puffing is in progress, etc.). The device information can include, but is not limited to, information such as power supply state, whether or not there is a malfunction, battery state (e.g., battery remaining, whether or not charging is required, etc.), etc. The smoking history information can include, but is not limited to, the cumulative number of smokes, etc.

[0053] The display unit 19 can visually display the various information by being provided with a visual display means such as an LED display, although the specific display means can be varied.

[0054] Next, the control unit 18 can generally control the operation of the sidestream smoke elimination device 1. For example, the control unit 18 can control the operation of the exhaust fan 162, can control the operation of the display unit 19, and can also control the operation of other components included in the sidestream smoke elimination device 1. The control unit 18 can also determine the progress of smoking on the smoking article 30, and can check the state of each component of the sidestream smoke elimination device 1 to determine whether the sidestream smoke elimination device 1 is in an operable state. The specific operation method of the control unit 18 will be described in detail below with reference to Figures 7 to 10.

[0055] The control unit 18 may be realized by at least one processor. The processor may be realized by an array of a number of logic gates, or may be realized by a combination of a general-purpose microprocessor and a memory in which a program that can be executed by the microprocessor is stored. In addition, a person having ordinary skill in the art to which the present disclosure pertains can obviously understand that the control unit 18 may be realized by other types of hardware.

[0056] 1 illustrates the control unit 18 as being located outside the housing 11 of the sidestream smoke removal device 1, this is merely for ease of understanding, and the location of the control unit 18 may vary. For example, the control unit 18 may be located at a specific position inside the housing 11 to prevent damage due to external impact.

[0057] Meanwhile, in some embodiments of the present disclosure, the sidestream smoke elimination device 1 may further include a module for providing an auditory and / or tactile output. For example, the sidestream smoke elimination device 1 may further include a speaker, a vibration module, etc. In such a case, the control unit 18 may provide various information to the user by further using the above-mentioned modules.

[0058] So far, the basic configuration of the sidestream smoke removal device 1 according to several embodiments of the present disclosure has been described with reference to Fig. 1. Hereinafter, various modified examples of the sidestream smoke removal device 1 described above will be described in detail with reference to Figs. 2 to 6. However, for the sake of clarity of the present disclosure, descriptions of contents that overlap with the above-described embodiments will be omitted.

[0059] FIG. 2 is an exemplary diagram for explaining a first modified example of the sidestream smoke removing device 1 according to some embodiments of the present disclosure.

[0060] As shown in FIG. 2, the sidestream smoke removal device 1 according to this modified example may further include a heating unit 40 disposed inside the housing 11 (ie, in the smoking space).

[0061] The heating unit 40 can remove odors generated by smoking by-products (e.g., cigarette ash, sidestream smoke, etc.) by heating the smoking space. This can improve the cleanliness of the smoking space and solve the problem of odors accumulated in the smoking space diffusing to the outside and causing discomfort to the user. The operation and heating temperature of the heating unit 40 can be controlled by the control unit 18.

[0062] Meanwhile, the shape, operating time, heating temperature (intensity), heating time, etc. of the heating unit 40 can be variously designed.

[0063] In some embodiments, the heating unit 40 may have a shape (e.g., an elongated shape as illustrated in FIG. 2, or a shape similar to the supporting unit 22 as illustrated in FIG. 5) and arrangement that can support the side of the smoking article 30. In such a case, the heating unit 40 may perform a role of supporting the smoking article 30 during smoking, and may perform a role of removing odors due to smoking by-products after smoking.

[0064] In some embodiments, the heating unit 40 can heat the smoking space to a temperature of about 50° C. to 200° C., and preferably to a temperature of about 70° C. to 180° C., about 90° C. to 150° C., or about 110° C. to 130° C. It has been confirmed that odors caused by smoking by-products can be effectively removed within these numerical ranges.

[0065] Also, in some embodiments, the heating temperature of the heating unit 40 may be determined based on the puff length or puff strength. For example, the control unit 18 may determine the heating temperature of the heating unit 40 to be a higher value as the puff length increases or the puff strength increases. This is because as the puff length increases (or the puff strength increases), the amount of smoking by-products (e.g., cigarette ash, sidestream smoke) generated also increases. In the opposite case, the control unit 18 may determine the heating temperature of the heating unit 40 to be a lower value. The puff length and puff strength may be measured in any manner.

[0066] Also, in some embodiments, the heating temperature of the heating unit 40 may be determined based on the smoking time. For example, the control unit 18 may determine the heating temperature of the heating unit 40 to be a higher value as the smoking time is longer. This is because the amount of smoking by-products (e.g., cigarette ash, sidestream smoke) generated increases as the smoking time is longer. In the opposite case, the control unit 18 may determine the heating temperature of the heating unit 40 to be a lower value. The smoking time may be determined by the difference between the smoking start and end times, and the smoking start and end times may be detected in any manner. For example, the control unit 18 may detect the smoking start and end times using the temperature sensor 20.

[0067] Also, in some embodiments, the operation time of the heating unit 40 may be determined based on the time of a puff. For example, the control unit 18 may operate the heating unit 40 every time a puff is detected. This is because smoking by-products are generated every time a puff is performed. The method of detecting a puff may be any method. For example, the control unit 18 may detect a puff using the temperature sensor 20, which will be described later.

[0068] Also, in some embodiments, the operation time of the heating unit 40 may be determined based on the end of smoking. For example, the control unit 18 may operate the heating unit 40 at the end of smoking. Alternatively, the control unit 18 may operate the heating unit 40 after the end of smoking (e.g., operate the heating unit 40 1 second after the end of smoking), or before the predicted end of smoking (e.g., operate the heating unit 40 1 second before the predicted end of smoking). Any method may be used to detect or predict the end of smoking. For example, the heating unit 40 may detect or predict the end of smoking using the temperature sensor 20, or may predict the end of smoking based on the number of puffs (e.g., predict that smoking will end when the number of puffs reaches a certain value).

[0069] Also, in some embodiments, the heating (operation) time of the heating unit 40 may be determined based on the smoking time. For example, the control unit 18 may determine the heating time of the heating unit 40 to be a larger value as the smoking time increases. This is because the amount of smoking by-products (e.g., cigarette ash, sidestream smoke) increases as the smoking time increases. In the opposite case, the control unit 18 may determine the heating time of the heating unit 40 to be a smaller value.

[0070] In addition, in some embodiments, the heating unit 40 may operate based on a combination of the various embodiments described above. For example, the control unit 40 may operate the heating unit 40 every time a puff is sensed, but may dynamically determine (adjust) the heating temperature of the heating unit 40 based on the length or strength of the sensed puff. Alternatively, the control unit 40 may operate the heating unit 40 after smoking has ended, but may dynamically determine (adjust) the heating time or heating temperature of the heating unit 40 based on the smoking time.

[0071] FIG. 3 is an exemplary diagram for explaining a second modified example of the sidestream smoke removing device 1 according to some embodiments of the present disclosure.

[0072] As shown in FIG. 3, the sidestream smoke removal device 1 according to this modified example may include a plurality of temperature sensors 20-1, 20-2 arranged at different positions in the smoking space. For example, the plurality of temperature sensors 20-1, 20-2 may be arranged in the length direction of the smoking article 30. Alternatively, the plurality of temperature sensors (e.g., 20-1, 20-2) may be arranged at positions facing each other. Although FIG. 2 illustrates an example in which two temperature sensors 20-1, 20-2 are arranged, the number of temperature sensors may be three or more. In this case, the arrangement intervals of the temperature sensors may be the same or different. When a plurality of temperature sensors (e.g., 20-1, 20-2) are used, the progress of smoking (e.g., the degree of progress of smoking) may be monitored more accurately, and various monitoring information may be obtained. However, the specific monitoring method may vary depending on the number and arrangement positions of the temperature sensors.

[0073] In some embodiments, the start of smoking may be sensed (determined) through a temperature sensor (e.g., 20-2) disposed near the upstream end of the smoking material portion. For example, the control unit 18 may determine that smoking has started when the temperature measured by the temperature sensor (e.g., 20-2) is equal to or higher than a reference value.

[0074] In some embodiments, the temperature measurements of multiple temperature sensors (e.g., 20-1, 20-2) arranged in the lengthwise direction may be compared to determine the progress of smoking (e.g., the current burning position) of the smoking article 30. This example will be described in more detail below with reference to Figures 8 and 9.

[0075] In some embodiments, multiple temperature sensors (e.g., 20-1, 20-2) may be arranged at positions facing each other as a reference for the inserted smoking article 30, or may be arranged in the circumferential direction of the smoking article 30 in the smoking space (e.g., four temperature sensors 20 arranged at 90 degree intervals). In this case, the degree of tilt (sway) of the smoking article 30 may be determined by comparing the measured temperatures of the multiple temperature sensors (e.g., 20-1, 20-2). For example, if the measured temperature of a specific temperature sensor is higher than that of other temperature sensors, the control unit 18 may determine that the smoking article 30 inserted in the direction of the specific temperature sensor is tilted. Alternatively, if the measured temperatures of the multiple temperature sensors (e.g., 20-1, 20-2) fluctuate by more than a reference value, the control unit 18 may determine that the inserted smoking article 30 is swaying.

[0076] FIG. 4 is an exemplary diagram for explaining a third modified example of the sidestream smoke removing device 1 according to some embodiments of the present disclosure.

[0077] As shown in Fig. 4, the sidestream smoke removal device 1 according to this modified example may further include an elastic support part 21 coupled to the ignition part 15. The elastic support part 21 is made of an elastic body capable of expanding and contracting, and may elastically support the upstream end of the inserted smoking article 30. For example, as the smoking article 30 is inserted, the ignition part 15 may come into close contact with the upstream end of the smoking article 30, and the elastic support part 21 may contract due to the insertion force, thereby stably supporting the smoking article 30. In addition, the elastic support part 21 may stably support smoking articles (e.g., 30) of various lengths (e.g., L1) through expansion and contraction, thereby greatly improving the usability of the sidestream smoke removal device 1.

[0078] Meanwhile, in some embodiments, at least a portion of the ignition portion 15 may have a pointed shape (e.g., needle-like) protruding toward the article insertion portion 12. In this case, as the smoking article 30 is inserted, the ignition portion 15 penetrates the upstream end of the smoking article 30, so that the smoking article 30 can be more firmly supported at the time of ignition. In addition, the problem of poor ignition due to the smoking article 30 shaking at the time of ignition can be greatly alleviated.

[0079] FIG. 5 is an exemplary diagram for explaining a fourth modified example of the sidestream smoke removing device 1 according to some embodiments of the present disclosure.

[0080] 5, the sidestream smoke removal device 1 according to this modified example may further include a support part 22 that supports the side of the smoking article 30 inserted into the smoking space. The support part 22 supports the side of the smoking article 30, thereby preventing the smoking article 30 from shaking during smoking.

[0081] The number, arrangement, shape, etc. of the support parts 22 may be designed in various ways. For example, as shown in the figure, a plurality of support parts 22 may be arranged to simultaneously support a side surface of a first portion and a side surface of a second portion of the smoking article 30. Also, in order to support a specific portion of the smoking article 30, a plurality of support parts 22 may be arranged in the circumferential direction of the smoking article 30 (e.g., four support parts 22 arranged at 90 degree intervals), or a single ring-shaped support part 22 may be arranged.

[0082] FIG. 6 is an exemplary diagram for explaining a fifth modified example of the sidestream smoke removing device 1 according to some embodiments of the present disclosure.

[0083] As shown in Fig. 6, the sidestream smoke removal device 1 according to this modified example may further include a cutting unit 23 disposed within the smoking space. The cutting unit 23 cuts the smoking article 30 during burning to prevent additional burning, thereby providing a safe extinguishing function at the time desired by the user and minimizing the risk of burns (e.g., the risk of burns due to carelessness when directly extinguishing) and the risk of fire that may occur due to carelessness of the user. However, the implementation method of the cutting unit 23 may be designed in various ways.

[0084] In some embodiments, the cutting portion 23 may be arranged at a fixed position and configured to cut a specific portion of the inserted smoking article 30. For example, the cutting portion 23 may be fixedly arranged at a position where it can cut between the filter portion and the smoking material portion. In this case, a safe extinguishing function may be ensured regardless of the current burning (smoking) position of the smoking article 30, and the structure of the sidestream smoke removal device 1 may be simplified.

[0085] In some other embodiments, the cutting unit 23 may be configured to be movable. For example, the cutting unit 23 may be configured to be moved by an external force (manual operation) of a user, or may be configured to be moved under the control of the control unit 18. As a more specific example, the cutting unit 23 may be automatically moved to the vicinity of the current burning (smoking) position of the smoking article 30 by the control unit 18. Please refer to the description of FIG. 9 for a method in which the control unit 18 determines the current burning (smoking) position of the smoking article 30.

[0086] Also, in some embodiments, the cutting unit 23 may be operated by a user pressing a push button (not shown) provided on the outer surface of the housing 11, twisting the housing 11, or lengthwise expanding or contracting the housing 11. The cutting unit 23 may have a structure that mechanically cooperates with the housing 11 so as to be operated by the above-exemplified actions, and the control unit 18 may be embodied to operate the cutting unit 23 by the above-exemplified actions.

[0087] Various modified examples of the sidestream smoke removing device 1 according to some embodiments of the present disclosure have been described above with reference to Figures 2 to 6. Hereinafter, a control method for the sidestream smoke removing device according to some embodiments of the present disclosure will be described with reference to Figure 7 and subsequent drawings.

[0088] Each step of the control method described below may be performed by a control unit (e.g., 18) of a sidestream smoke removal device (e.g., 1). Also, each step of the control method may be embodied by one or more instructions executed by the control unit. The control method may be applied to various types of sidestream smoke removal devices, but for ease of understanding, the description will be continued assuming that it is performed in the sidestream smoke removal device 1 illustrated in Figures 1 to 6. Therefore, when the subject of a particular operation is omitted in the following description, it can be understood that it is performed by the control unit 18 of the illustrated device 1.

[0089] 7 is an exemplary flowchart showing a method for controlling a sidestream smoke removal device according to some embodiments of the present disclosure, however, this is merely a preferred embodiment for achieving the object of the present disclosure, and it goes without saying that some steps may be added or deleted as necessary.

[0090] 7, the control method may begin with step S10 of detecting the start of smoking. There may be various ways to detect the start of smoking in this step.

[0091] In some embodiments, the control unit 18 may detect the start of smoking through a user input (e.g., a button input, etc.) that activates the ignition unit 15. Alternatively, the control unit 18 may recognize the start of smoking through a user input (e.g., a button input, etc.) that requests the start of smoking and activate the ignition unit 15.

[0092] In some other embodiments, the control unit 18 may detect the start of smoking in response to determining that the temperature measured by the temperature sensor 20 is equal to or greater than a reference value. In this case, the temperature sensor 20 may be disposed to measure the temperature near the upstream end of the smoking article 30 within the smoking space, for example.

[0093] In step S20, in response to the start of smoking being detected, the control unit 18 may open (e.g., partially open or fully open) the vent hole 111. This is because the outside air flowing in through the vent hole 111 can promote the combustion of the smoking article 30. In addition, the control unit 18 may operate the exhaust fan 162. This is because the operation of the exhaust fan 162 can smoothly exhaust sidestream smoke generated during smoking.

[0094] Meanwhile, according to some embodiments of the present disclosure, the control unit 18 may control the vent hole 111 and the exhaust fan 162 based on a puff event of the user during smoking. However, the specific control method may vary.

[0095] In some examples, the control unit 18 may adjust the degree of opening / closing of the vent hole 111 based on a puff event. Specifically, the control unit 18 may open the vent hole 111 more when puffing and open the vent hole 111 less when not puffing. In this case, outside air may flow in more smoothly when puffing, and the combustion of the smoking article 30 may be promoted more. Also, the problem of unpurified sidestream smoke leaking through the vent hole 111 when not puffing may be mitigated. Incidentally, since not much sidestream smoke is generated when puffing and an airflow path through which gas flows in through the vent hole 111 is formed, the problem of sidestream smoke leaking even when the vent hole 111 is opened may not occur.

[0096] In some other examples, the control unit 18 may operate (rotate) the exhaust fan 162 in the reverse direction when puffing, and operate (rotate) the exhaust fan 162 in the forward direction when not puffing. Here, the forward direction may refer to a rotation direction in which sidestream smoke is drawn toward the filter structure 161, and the reverse direction may refer to the opposite rotation direction. In this case, when puffing, airflow may concentrate toward the upstream end of the smoking article 30 to promote combustion, and when not puffing, sidestream smoke may be drawn toward the filter structure 161 to be smoothly exhausted.

[0097] In some other examples, the control unit 18 may adjust the degree of opening and closing of the vent hole 111 and / or the rotation speed of the exhaust fan 162 based on information on the puff event (e.g., puff strength, puff interval, puff length, etc.). For example, if the puff strength increases, the puff length increases, or the puff interval decreases, the control unit 18 may open the vent hole 111 more. In the opposite case, the control unit 18 may open the vent hole 111 less. This is because the puff strength is likely to increase when the smoking article 30 is not burned smoothly. Alternatively, if the puff strength increases, the puff length increases, or the puff interval decreases, the control unit 18 may increase the rotation speed of the exhaust fan 162 during puffing (i.e., the rotation speed in the reverse direction). In the opposite case, the control unit 18 may decrease the rotation speed of the exhaust fan 162.

[0098] In still other examples, the control unit 18 may perform control based on a combination of the examples described above.

[0099] In the above embodiment, the control unit 18 may detect a puff in various ways. For example, the control unit 18 may detect a puff based on a change in temperature measured by the temperature sensor 20. Specifically, the control unit 18 may recognize that a puff has occurred when the degree of temperature change is equal to or greater than a reference value (e.g., when the combustion temperature of the smoking article 30 rises instantaneously). This may be understood as utilizing the phenomenon in which combustion accelerates at the upstream end of the smoking article 30 when a puff is made. The control unit 18 may also determine the puff strength based on the degree of temperature change. For example, the control unit 18 may determine that the puff strength is stronger as the degree of temperature change increases, and that the puff strength is weaker as the degree of temperature change decreases.

[0100] In step S30, the control unit 18 may detect the end of smoking. In this step, the control unit 18 may detect the end of smoking in various ways, which may vary depending on the embodiment.

[0101] In some embodiments, the controller 18 may detect the end of smoking based on the temperature measured by the temperature sensor 20. In this case, the temperature sensor 20 may be disposed, for example, near the downstream end of the smoking material portion of the smoking article 30. For example, the controller 18 may determine that smoking has ended when the temperature measured by the temperature sensor 20 is equal to or greater than a reference value, or when the measured temperature increases and then decreases.

[0102] In some other embodiments, the control unit 18 may detect the end of smoking based on the time elapsed since smoking began, a puff event, etc. For example, the control unit 18 may determine that smoking has ended if a certain amount of time has elapsed since smoking began, if the number of puffs is equal to or exceeds a reference value, or if no puffs are detected for a certain amount of time after the most recent puff.

[0103] In still other embodiments, a smoking cessation condition may be set. For example, the smoking cessation condition may be set based on the number of puffs, the elapsed smoking time, etc. In such a case, the control unit 18 may determine the end of smoking in response to the preset smoking cessation condition being satisfied.

[0104] In response to the detection of the end of smoking in step S40, the control unit 18 may perform an automatic extinguishing function. In this step, the control unit 18 may perform the automatic extinguishing function in various ways.

[0105] In some embodiments, the control unit 18 can close the vent hole 111 and stop the operation of the exhaust fan 162. In this case, the inflow of outside air is interrupted by the closure of the vent hole 111, and the smoking article 30 can be naturally extinguished due to lack of oxygen.

[0106] In some other embodiments, the control unit 18 can close the vent hole 111 and stop the exhaust fan 162 after operating for a certain period of time or operate it continuously. In this case, the inflow of outside air is stopped by closing the vent hole 111, and the internal air is exhausted to the outside through the exhaust fan 162, so that the smoking article 30 can be naturally extinguished.

[0107] In still other embodiments, the control unit 18 may perform an automatic extinguishing function by operating the cutting unit 23.

[0108] In some other embodiments, the control unit 18 may perform the automatic extinguishing function based on a combination of the above-mentioned embodiments. For example, the control unit 18 may perform the automatic extinguishing function through a first extinguishing process of closing the vent hole 111 and stopping the operation of the exhaust fan 162, and a second extinguishing process of cutting the inserted smoking article 30 through the cutting unit 23. In this case, the first extinguishing process and the second extinguishing process may be performed in any order.

[0109] Meanwhile, according to some embodiments of the present disclosure, the control unit 18 may operate the exhaust fan 162 in the forward direction (i.e., in the inhalation direction) for a certain period of time in response to the end of smoking being detected. In this case, the exhaust fan 162 causes smoking by-products such as cigarette ash to gather near the filter structure 161, so that the inside of the sidestream smoke removal device 1 may be more easily cleaned. In some examples, the control unit 18 may adjust the rotation speed of the exhaust fan 162 based on the degree of reduction in the smoking articles 30. For example, when the smoking articles 30 are completely consumed, since there should be more by-products, the control unit 18 may rotate the exhaust fan 162 faster, and in the opposite case, may rotate it slower. The degree of reduction in the smoking articles 30 may be determined based on the number of puffs, the smoking elapsed time, the current burning (smoking) position (see FIG. 9), etc.

[0110] In step S50, the control unit 18 may operate the heating unit 40 to heat the smoking space. By doing so, odors generated by smoking by-products in the smoking space may be effectively eliminated. However, depending on the circumstances, the control unit 18 may operate the heating unit 40 periodically or non-periodically even during smoking. For example, the control unit 18 may operate the heating unit 40 every time a puff is detected in order to quickly eliminate odors of smoking by-products generated by a puff.

[0111] The operating time, heating temperature, heating time, etc. of the heating unit 40 may be variously designed, but in order to avoid repetition, the description thereof will be omitted.

[0112] Meanwhile, FIG. 7 illustrates an example in which steps S40 and S50 are performed in sequence, but this is merely for convenience of understanding, and steps S40 and S50 may be performed in an order different from that illustrated, or may be performed simultaneously.

[0113] Thus far, the control method of the sidestream smoke removal device according to some embodiments of the present disclosure has been described with reference to Fig. 7. According to the above-described method, the vent hole 111 and the exhaust fan 162 can be appropriately controlled according to the progress of smoking, so that the user's satisfaction with the device can be improved. In addition, an automatic extinguishing function is performed when smoking is finished, so that the risk of fire and burns due to user carelessness can be minimized. Furthermore, the cleanliness of the sidestream smoke removal device 1 can be improved by effectively removing odors remaining in the smoking space through heating.

[0114] Hereinafter, a control method of a sidestream smoke removal device according to some other embodiments of the present disclosure will be described with reference to Fig. 8. However, for the sake of clarity of the present disclosure, a description of the contents overlapping with the control method illustrated in Fig. 7 will be omitted.

[0115] 8 is an exemplary flowchart showing a control method of a sidestream smoke removal device according to some other embodiments of the present disclosure, however, this is merely a preferred embodiment for achieving the object of the present disclosure, and it goes without saying that some steps may be added or deleted as necessary.

[0116] 8, the control method may begin with step S110 of detecting the start of smoking. In this step, the control unit 18 may display an indication notifying the start of smoking through the display unit 19. For further description of this step, please refer to step S10 illustrated in FIG.

[0117] In step S120, the control unit 18 may monitor the smoking progress. Here, the smoking progress may include all circumstances related to smoking, such as the degree of smoking progress, puff events, etc.

[0118] In some embodiments, the control unit 18 can compare the temperatures measured by multiple temperature sensors 20 arranged at different positions to accurately determine the progress of smoking of the smoking article 30 (or the current smoking (combustion) position). Specifically, as shown in FIG. 9, assume that multiple temperature sensors 20-1, 20-2, and 20-3 are arranged in the length direction in the smoking space inside the sidestream smoke removal device 1. Then, the control unit 18 can compare the temperatures measured by the first temperature sensor 20-1, the second temperature sensor 20-2, and the third temperature sensor 20-3 to determine the current combustion (smoking) position and the progress of smoking of the smoking article 30. For example, if the measured temperature of the first temperature sensor 20-1 is the lowest, the measured temperature of the second temperature sensor 20-2 is lower than that of the third temperature sensor 20-3, and the measured temperature of the third temperature sensor 20-3 is the highest, the control unit 18 can determine that the current burning (smoking) position of the smoking article 30 is between the second temperature sensor 20-2 and the third temperature sensor 20-3 and is closer to the third temperature sensor 20-3. In this case, the control unit 18 can determine that the greater the temperature difference between the second temperature sensor 20-2 and the third temperature sensor 20-3, the closer the position is to the third temperature sensor 20-3.

[0119] In step S130, the control unit 18 can display the monitoring information through the display unit 19. However, the type of monitoring information and a specific display method thereof can be designed in various ways.

[0120] In some embodiments, the control unit 18 may display information regarding the progress of smoking through the display unit 19. For example, the control unit 18 may control the display unit 19 to display an indication (e.g., a cigarette-shaped object) indicating the smoking article 30 (or the progress of smoking) and to reduce the length of the indication as smoking progresses. As another example, as illustrated in Fig. 10, the control unit 18 may control the display unit 19 to display an indication area (e.g., an LED-lit area / section) indicating the progress of smoking through the display unit 19 and to change the size of the indication area (e.g., the number of LED-lit areas / sections) as smoking progresses. In this case, the size of the display area may increase or decrease as smoking progresses.

[0121] In some other embodiments, the control unit 18 may display information about the puff event through the display unit 19. For example, the control unit 18 may display the number of puffs. As another example, the control unit 18 may display an indication indicating that a puff is occurring in response to detecting a puff.

[0122] In step S140, the control unit 18 may detect the end of smoking. In this step, the control unit 18 may display an indication indicating the end of smoking through the display unit 19. For further description of this step, please refer to the description of step S30 illustrated in FIG. 7.

[0123] On the other hand, if the end of smoking is detected, the control unit 18 may perform the automatic extinguishing function and display a display indicating the automatic extinguishing through the display unit 19, and if the automatic extinguishing is completed, a display indicating the completion of the automatic extinguishing may be displayed.

[0124] So far, the control method of the sidestream smoke removal device according to some other embodiments of the present disclosure has been described with reference to Figures 8 to 10. According to the above-described method, information on the progress of smoking can be displayed through the display unit 19. As a result, the user can check the progress of smoking in real time through the display unit 19, which can greatly improve convenience and safety of use.
