Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

1 is an exemplary diagram illustrating an apparatus 1 for removing sidestream smoke according to some embodiments of the present disclosure. In particular, the drawings such as FIG. 1 show a state in which the smoking article 30 is inserted.

As shown in FIG. 1 , the sidestream smoke removal device 1 includes a housing 11 , an article insertion unit 12 , a back cover 13 , an insulating unit 14 , a temperature sensor 20 , and an ignition unit 15 . , it may include a side stream processing unit 16 , a mesh network 17 , a display unit 19 , and a control unit 18 . However, only the components related to the embodiment of the present disclosure are illustrated in FIG. 1 . Accordingly, those of ordinary skill in the art to which the present disclosure pertains can see that other general-purpose components other than those shown in FIG. 1 may be further included. For example, the sidestream smoke removal device 1 may further include a battery (not shown) for supplying power to the electrical components (eg, the control unit 18, the display unit 19, etc.). Also, some of the components shown in FIG. 1 may not be essential components of the sidestream smoke removal device 1 . That is, the sidestream smoke removal device 1 may be implemented in a form in which some of the illustrated components are omitted. For example, the sidestream smoke removal device 1 may not include the display unit 19 . Hereinafter, each component of the sidestream smoke removal device 1 will be described.

The housing 11 may form a smoking space inside the sidestream smoke removal device 1 , and may form at least a part of an exterior of the sidestream smoke removal device 1 . 1 shows the housing 11 as referring to the sidewall of the sidestream smoke removal device 1 , the housing 11 includes an article inserting unit 12 , a back cover 13 and an insulating unit 14 . It may refer to all of the exterior forming structures. In order to ensure the durability of the sidestream smoke removal device 1 and minimize the risk of breakage, the housing 11 may be preferably made of a solid material.

In some embodiments, a vent hole 111 may be formed in the housing 11 to smoothly introduce outside air into the smoking space. The vent hole 111 may promote combustion of the smoking article 30 by allowing outside air to flow in during smoking. Accordingly, the smoking function of the sidestream smoke removal device 1 may be greatly improved. Although FIG. 1 illustrates that one vent hole 111 is formed in the housing 11 as an example, the number of the vent hole 111 may be plural. In addition, the formation position, size, spacing, etc. of the vent hole 111 may be variously designed. Whether and/or the degree of opening and closing of the vent hole 111 may be controlled by the control unit 18, which will be described later with reference to FIG. 11 in this regard.

Next, the article insertion part 12 is located at one end (e.g. the upper end) of the housing 11, and may form an opening for the smoking article 30 to be inserted. The user may insert the smoking article 30 into the smoking space in the sidestream smoke removal device 1 through the article insertion unit 12 . In order to block the heat inside the smoking space from being emitted to the outside, it may be preferable that the article inserting part 12 is made of a heat insulating material. In addition, in order to prevent the inserted smoking article 30 from shaking, it may be preferable that the article insertion unit 12 has a holder structure capable of holding the smoking article 30 .

In some embodiments, the article inserting unit 12 may have a structure in which the size of the opening can be adjusted. For example, the article inserting unit 12 may have a structure in which the opening can be tightened or loosely expanded through manual manipulation. As another example, the article insert 12 may be configured to automatically tighten the opening to fit the smoking article 30 . As a more specific example, the article inserting unit 12 is controlled by the controller 18, and the controller 18 detects that the smoking article 30 is inserted through a sensor or a user input (e.g. button push) is received. It may be controlled to tighten the opening of the article inserting unit 12 when the product is inserted. According to the present embodiment, since the size of the opening is adjusted to fit the smoking article 30 , the shaking phenomenon of the smoking article 30 can be prevented and support stability can be improved. Furthermore, since smoking articles of various sizes can be inserted, the utility of the sidestream smoke removal device 1 can be improved.

The smoking article 30 may be composed of a filter part located downstream and a smoking material part bordering the upstream end of the filter part. However, the detailed structure of the smoking article 30 may vary. The filter unit may include a filter material capable of filtering smoke, and the smoking material unit may include a smoking material. Examples of the smoking article 30 may include, but are not limited to, a combustion cigarette, and the smoking article 30 may include any article that generates sidestream smoke during smoking.

Next, the back cover 13 may be located at the other end (e.g. lower end) of the housing 11 to function as a cover of the sidestream smoke removal device 1 . A gas discharge passage may be formed in the back cover 13 so that the sidestream smoke treated (purified) through the sidestream smoke processing unit 16 can be discharged to the outside. For example, a gas discharge passage such as a micro hole may be formed in the back cover 13 .

Next, the heat insulating part 14 may be made of a material having low thermal conductivity to block heat from being emitted from the inside of the smoking space to the outside. The heat insulating part 14 is disposed on the outer surface of the housing 11 to prevent the risk of burns due to internal heat when the user's body comes into contact with the sidestream smoke removal device 1 (e.g. when holding the device 1 for smoking) can play a role.

Next, the temperature sensor 20 may be disposed in the smoking space to measure the temperature of the smoking article 30 inserted into the smoking space. The number, shape, arrangement position, arrangement interval, etc. of the temperature sensors 20 may be designed in various ways, which may vary depending on the embodiment.

As shown in FIG. 1 , a temperature sensor 20 may be arranged to measure the temperature near the downstream end of the smoking material portion. In this case, whether or not smoking is terminated can be accurately determined using only the temperature sensor 20 without an additional monitoring module, which can be understood as taking advantage of the fact that smoking is usually terminated when the smoking material part is completely burned. For example, when the temperature measured by the temperature sensor 20 is greater than or equal to the reference value (e.g., when the current smoking position reaches the downstream end of the smoking material unit), the temperature measured by the temperature sensor 20 increases and then falls below the reference value. When it decreases (e.g. when the combustion power is weakened at the downstream end of the smoking material part), it can be judged that smoking has ended.

In some other embodiments, the plurality of temperature sensors 20 may be disposed at different positions within the smoking space. For example, as illustrated in FIG. 2 , a plurality of temperature sensors 20 - 1 and 20 - 2 may be disposed in the longitudinal direction of the smoking article 30 . Alternatively, the plurality of temperature sensors 20 may be disposed at positions facing each other. Although FIG. 2 illustrates that two temperature sensors 20-1 and 20-2 are disposed as an example, the number of temperature sensors 20 may be three or more. In this case, the arrangement interval of the temperature sensor 20 may be the same or different. When a plurality of temperature sensors 20 are used, the smoking progress (e.g. smoking progress) can be monitored more accurately, and various monitoring information can be obtained as follows.

In some examples, the onset of smoking may be detected (determined) through a 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 measured temperature of the temperature sensor (e.g. 20-2) is equal to or greater than a reference value.

In some examples, the smoking progress (e.g. current smoking (burning) position) of the smoking article 30 is determined by comparing the measured temperatures of a plurality of temperature sensors (e.g. 20-1, 20-2) disposed in the longitudinal direction. can This example will be described in more detail later with reference to FIGS. 12 and 13 .

In some examples, the plurality of temperature sensors 20 are disposed at positions opposite to each other with respect to the inserted smoking article 30 or disposed in the circumferential direction of the smoking article 30 in the smoking space (e.g. at intervals of 90 degrees) Four temperature sensors 20 can be arranged). In this case, the degree of inclination (shaking) of the smoking article 30 may be determined by comparing the measured temperatures of the plurality of temperature sensors 20 . For example, when the measured temperature of the specific temperature sensor is higher than that of the other temperature sensors, the controller 18 may determine that the smoking article 30 inserted in the direction of the specific temperature sensor is inclined. Alternatively, when the temperature measured by the plurality of temperature sensors 20 varies by more than a reference value, the controller 18 may determine that the inserted smoking article 30 is shaking.

In some other embodiments, a temperature sensor 20 having an elongated body may be disposed in a smoking space. For example, the elongated temperature sensor 20 may be disposed in the longitudinal direction of the smoking article 30 . In the temperature sensor 20 according to the present embodiment, the first part of the elongated body can measure the temperature of the first corresponding part of the smoking material part constituting the smoking article 30, and the second part is the second part of the smoking material part. 2 It may be implemented to measure the temperature of the corresponding part. The specific implementation method may be any method. In this case, the smoking progress may be monitored based on the measured temperature of a specific part of the elongated body. For example, the controller 18 may determine the smoking progress of the smoking article 30 by comparing the measured temperatures of each part of the elongated body.

In some other embodiments, the temperature sensor 20 may be disposed based on a combination of the above-described embodiments.

Next, the ignition unit 15 may be disposed in the smoking space to ignite the smoking article 30 inserted into the smoking space. The ignition unit 15 may be controlled by the control unit 18, and may perform an ignition function by a user's manual operation. The number, shape, arrangement, etc. of the ignition units 15 may be designed in various ways, which may vary depending on the embodiment.

In some embodiments, the ignition unit 15 may be disposed in a fixed position. Specifically, as shown in FIG. 1 , the ignition unit 15 may be arranged 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 is simplified, and thus the defective rate during manufacturing can be minimized.

In some other embodiments, the ignition unit 15 may be designed and implemented to be movable. No matter what the specific implementation method is, it is free. For example, the ignition unit 15 may be implemented to be moved in the longitudinal direction by a user's manual operation or control of the controller 18 . In some instances, the control 18 may move the ignition 15 to the upstream end of the smoking article 30 in response to detecting the insertion of the smoking article 30 . According to the present embodiment, the sidestream smoke removal device 1 can be universally applied to smoking articles of various lengths, so that the utility of the sidestream smoke removal device 1 can be greatly improved.

Next, the sidestream smoke processing unit 16 may be disposed in the smoking space to perform various treatments on sidestream smoke generated from the inserted smoking article 30 . For example, the sidestream smoke processing unit 16 may be positioned between the inserted smoking article 30 and the back cover 13 to perform a purifying function for sidestream smoke. In addition, the sidestream smoke processing unit 16 may further perform an exhaust function so that the purified sidestream smoke is well discharged to the outside. However, the detailed structure and operation method of the sidestream smoke processing unit 16 may be designed in various ways, which may vary depending on the embodiment.

In some embodiments, as shown, the sidestream smoke processing unit 16 may be configured to include a filter structure 161 and an exhaust fan 162 . The filter structure 161 may perform a function of purifying the sidestream smoke, and the exhaust fan 162 may perform an exhaust function of the sidestream smoke. For example, the exhaust fan 162 may rotate to suck the sidestream smoke toward the filter structure 161 , and allow the sidestream smoke that has passed through the filter structure 161 to be smoothly discharged 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 FIG. 11 and the like.

Next, the mesh network 17 may be disposed between the sidestream smoke processing unit 16 and the back cover 13 to serve as a safety net. For example, the mesh network 17 may prevent a specific object (eg, a part of the filter unit 161 , etc.) inside the smoking space from being separated in the direction of the back cover 13 .

Next, the display unit 19 may be positioned on the outer surface of the housing 11 to display various types of information under the control of the control unit 18 . For example, the display unit 19 may display information on smoking progress, device information, smoking history information, user information, and the like. Here, the smoking progress information may include, for example, smoking progress information (e.g. all information related to smoking progress, such as smoking progress, current smoking location, number of puffs remaining, smoking time, remaining smoking time, etc.), puff information (e.g. puff) all information related to the puff event, such as the number of times, puff length, puff interval, puff strength, whether or not a puff is in progress, etc.), but is not limited thereto. The device information may include, but is not limited to, information such as, for example, a power state, whether there is a failure, a battery state (eg, remaining battery level, whether charging is required, etc.). The smoking history information may include, but is not limited to, the cumulative number of cigarettes smoked.

The display unit 19 is provided with a visual display means such as an LED display, so that the various information can be visually displayed. However, the specific display means may vary freely.

Next, the control unit 18 may control the overall operation of the sidestream smoke removal device 1 . For example, the control unit 18 may control the operation of the exhaust fan 162 , may control the operation of the display unit 19 , and may also control the operation of other components included in the sidestream smoke removal device 1 . can be controlled In addition, the control unit 18 may determine the smoking progress of the smoking article 30 , and check the state of each of the components of the sidestream smoke removal device 1 to determine whether the sidestream smoke removal device 1 is in an operable state can also be judged. A detailed operation method of the control unit 18 will be described in detail later with reference to FIGS. 11 to 13 .

The control unit 18 may be implemented by at least one processor. The processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable in the microprocessor is stored. In addition, those of ordinary skill in the art to which the present disclosure pertains can clearly understand that the control unit 18 may be implemented with other types of hardware.

1 shows the control unit 18 as being located outside the housing 11 of the sidestream smoke removal device 1, this is only for convenience of understanding, and the arrangement position of the control unit 18 may be changed. For example, in order to prevent a failure due to an external impact, the control unit 18 may be disposed at a specific position within the housing 11 .

On the other hand, in some embodiments of the present disclosure, the sidestream smoke removal device 1 may further include a module for providing an audible and/or tactile output. For example, the sidestream smoke removal device 1 may further include a speaker, a vibration module, and the like. In this case, the control unit 18 may provide various types of information to the user by further using the illustrated modules.

In addition, in some embodiments of the present disclosure, as shown in FIG. 3 , the elastic support part 21 disposed to elastically support the upstream end of the smoking article 30 into which the sidestream smoke removal device 1 is inserted is provided. may include The elastic support part 21 may include an elastic body capable of stretching and contracting, such as a spring, and may be arranged to contract in the insertion direction as the smoking article 30 is inserted. For example, the elastic support part 21 may be disposed in the longitudinal direction in the smoking space and contracted in the insertion direction by the insertion force of the smoking article 30 to support the smoking article 30, and accordingly, the smoking article 30 support stability and ignition stability can be improved.

In the previous embodiments, as shown, the ignition part 15 is coupled to the elastic support part 21 , and as the smoking article 30 is inserted, the ignition part 15 is the upstream end of the smoking article 30 . It may be arranged to be in close contact with the In this case, since the ignition part 15 performs an ignition function while supporting the upstream end of the smoking article 30 together with the elastic support part 21 , ignition stability may be further improved and ignition performance may also be improved. In this example, the portion of the ignition unit 15 in close contact with the upstream end of the smoking article 30 may be formed in a sharply protruding shape (e.g. needle shape). In this case, as the smoking article 30 is inserted, at least a part of the ignition unit 15 penetrates the upstream end of the smoking article 30, so that the smoking article 30 can be more stably supported during ignition. , thus the support stability and ignition stability of the sidestream smoke removal device 1 can be further improved.

In addition, in some embodiments of the present disclosure, as shown in FIG. 4 , a support part 22 for supporting the side surface of the smoking article 30 may be further disposed in the smoking space of the sidestream smoke removal device 1 . For example, as shown, a plurality of support parts 22 may be disposed to support the side surface of the first point and the side surface of the second point of the smoking article 30 . In order to support a specific point of the smoking article 30, a plurality of support parts 22 may be disposed in the circumferential direction of the smoking article 30 (e.g. four support parts 22 disposed at intervals of 90 degrees), and may be formed in a ring shape. A single support 22 may be disposed. As such, the number, arrangement, and shape of the support parts 22 may be designed and implemented in various ways.

In addition, in some embodiments of the present disclosure, the sidestream smoke removal device 1 may further include a cutting portion ( 23 in FIG. 5 ). The cutting unit 23 cuts the burning smoking article 30 to prevent additional combustion, thereby providing a user-friendly and safe fire extinguishing function at the user's desired time, and the risk of burns that may occur due to the user's carelessness ( e.g. risk of burns due to carelessness in case of direct fire extinguishing) and fire risk can be minimized. This embodiment will be described in more detail later with reference to the drawings below with reference to FIG. 5 .

So far, the structure and some modifications of the sidestream smoke removal apparatus 1 according to some embodiments of the present disclosure have been described with reference to FIGS. 1 to 4 . As described above, information on the smoking progress may be provided through the plurality of temperature sensors 20 and the display unit 19 , and the smoking article 30 through the elastic support unit 22 and/or the support unit 23 . ) support stability and ignition stability can be improved. Accordingly, the convenience of use of the sidestream smoke removal device 1 may be improved, and user satisfaction may be improved.

Hereinafter, the sidestream smoke removal apparatus 1 having a fire extinguishing function according to some embodiments of the present disclosure will be described in detail with reference to FIG. 5 and the following drawings. However, for clarity of the present disclosure, a description of the content overlapping with FIGS. 1 to 4 will be omitted.

5 is an exemplary view for explaining the class removal device 1 having a fire extinguishing function according to some embodiments of the present disclosure.

As shown in FIG. 5 , the sidestream smoke removal device 1 may include a cutting unit 23 that provides a fire extinguishing function by cutting the inserted smoking article 30 . However, the arrangement shape, operation method, and/or the cutting structure of the cutting unit 23 may be designed in various ways.

First, the arrangement form of the cutting part 23 may be designed in various ways as follows.

In some examples, the cutout 23 may be configured to be disposed in a fixed position to cut a specific portion of the inserted smoking article 30 . For example, the cutting unit 23 may be fixedly disposed at a position capable of cutting between the filter unit and the smoking material unit. In this case, a safe fire extinguishing function can be ensured regardless of the current smoking (combustion) position of the smoking article 30 , and the structure of the sidestream smoke removal device 1 can be simplified.

In some other examples, the cutout 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 the 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 smoking (burning) position of the smoking article 30 by the control unit 18 . The method in which the control unit 18 determines the current smoking (burning) position of the smoking article 30 will be described with reference to FIG. 13 .

Next, the operation method of the cutting part 23 may be designed in various ways as follows.

Also, in some examples, as illustrated in FIG. 6 , a push-type button 24 may be provided on the outer surface of the housing 11 . And, the cutout 23 may be configured to be operated as an external force F is applied to the push-type button 24 (ie, as the user pushes the button 24). For example, the cutting part 23 may be configured to mechanically interlock with the push-type button 24 to cut the smoking article 30 by an external force F applied to the push-type button 24 . Alternatively, the cutting unit 23 may be electrically interlocked with the control unit 18 , and the control unit 18 may operate the cutting unit 23 in response to the external force F of the push-type button 24 .

In some other examples, as illustrated in FIG. 7 , the cutout 23 may be configured to actuate as an external force F that twists the housing 11 is applied to the housing 11 . For example, the cutting part 23 is mechanically interlocked with the housing 11, so that the smoking article 30 is cut by an external force that twists the housing 11 (F; e.g. when holding the housing 11 with both hands and turning it in the opposite direction). can be configured to cut. Alternatively, the cutting unit 23 may be electrically interlocked with the control unit 18 , and the control unit 18 may operate the cutting unit 23 in response to the external force F.

In some other examples, as illustrated in FIG. 8 , the cutout 23 may be configured to actuate as an external force F1 or F2 that expands or contracts the housing 11 is applied to the housing 11 . . For example, the cutting part 23 is mechanically interlocked with the housing 11, thereby extending the housing 11 by an external force (F1; e.g. when holding the housing 11 with both hands and pulling it in the opposite direction) or contracting an external force (F2; e.g. It may be configured to cut the smoking article 30 by holding the housing 11 with both hands and pushing it in the opposite direction). Alternatively, the cutting unit 23 may be electrically interlocked with the control unit 18 , and the control unit 18 may operate the cutting unit 23 in response to the extension or contraction external force F1 or F2 .

Next, the cut structure of the cut portion 23 may also be designed in various ways as follows.

In some examples, as illustrated in FIG. 9 , the cutting portion 23-1 may include a plurality of cutting

blades

231 and 232, and an opening formed in the vicinity of the center to allow the smoking article 30 to pass therethrough. can For example, as the smoking article 30 is inserted into the smoking space, the smoking article 30 may be designed to pass through the opening of the cut-out portion 23-1. In addition, the cutting unit 23-1 may be configured to cut the smoking article 30 as the plurality of cutting

blades

231 and 232 that have been spread are retracted. The plurality of cutting

blades

231 and 232 may be disposed in the circumferential direction (e.g. 0 clockwise or counterclockwise direction) of the opening, and the number may vary. This cutting structure of the cutting part 23 - 1 may be understood as similar to the folding structure of the folding steamer.

In some other examples, as illustrated in FIG. 10 , the cutting part 23-2 includes a plurality of cutting

blades

231 and 232, and an opening formed in the vicinity of the center to allow the smoking article 30 to pass therethrough. can do. For example, as the smoking article 30 is inserted into the smoking space, the smoking article 30 may be designed to pass through the opening of the cutting part 23-2. In addition, the cutting part 23-2 may be configured to cut the smoking article 30 as the plurality of cutting

blades

233 and 234 move in a direction to reduce the opening (ie, a direction to decrease the size of the opening). . The plurality of cutting

blades

233 and 234 may be arranged in a circumferential direction (e.g. clockwise or counterclockwise direction) of the opening, and overlapping area between the plurality of cutting

blades

233 and 234 as it moves in the direction of reducing the opening This may be designed to increase, the number of cutting blades (233, 234) can be varied as much as possible. Such a cutting structure of the cutting unit 23 - 2 may be understood as similar to the diaphragm structure of a camera.

In still some other examples, the cut portion 23 may have a cut structure different from that described above.

The various examples described so far may be combined in various forms to implement the cutting part 23 . For example, the cutting unit 23 is operated as illustrated in FIG. 7 , has a cutting structure illustrated in FIG. 9 , and may be implemented to be movable by a user's manual operation.

So far, the sidestream smoke removal apparatus 1 having a fire extinguishing function according to some embodiments of the present disclosure has been described with reference to FIGS. 5 to 10 . According to the above, by providing the cutting unit 23 as the fire extinguishing means, a user-friendly and safe fire extinguishing function can be provided at the user's desired time, and the risk of burns that may occur due to the user's carelessness (e.g. due to carelessness during direct fire extinguishing) burn hazard) and fire hazard can be minimized. Accordingly, the ease of use and safety of the sidestream smoke removal device 1 can be greatly improved.

Hereinafter, a control method according to some embodiments of the present disclosure will be described with reference to the drawings below with reference to FIG. 11 .

Each step of the control method to be described below may be performed by the control unit e.g. 18 of the sidestream smoke removal device e.g. 1 . In addition, each step of the control method may be implemented with one or more instructions executed by the control unit. The control method may be applied to various types of sidestream smoke removal apparatus, but for convenience of understanding, it is assumed that the control method is performed in the sidestream smoke removal apparatus 1 illustrated in FIGS. 1 to 10 and the description will be continued. Therefore, in the following description, when the subject of a specific operation is omitted, it can be understood that it is performed by the controller 18 of the exemplified apparatus 1 .

11 is an exemplary flowchart illustrating a control method according to some embodiments of the present disclosure. However, this is only a preferred embodiment for achieving the purpose of the present disclosure, and it goes without saying that some steps may be added or deleted as needed.

11 , the control method may be started in step S10 of detecting the start of smoking. There may be various ways to detect the start of smoking in this step.

In some embodiments, the control unit 18 may detect the start of smoking through a user input (eg, a button input, etc.) for operating the ignition unit 15 . Alternatively, the controller 18 may recognize the start of smoking through a user input requesting to start smoking (eg, a button input, etc.) and operate the ignition unit 15 .

In some other embodiments, the controller 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, for example, arranged to measure the temperature near the upstream end of the smoking article 30 in the smoking space.

In step S20, in response to detecting the start of smoking, the control unit 18 may open the vent hole 111 (e.g. partially open, all open). This is because the outside air introduced through the vent hole 111 can promote combustion of the smoking article 30 . Also, the controller 18 may operate the exhaust fan 162 . This is because sidestream smoke generated during smoking can be smoothly exhausted as the exhaust fan 162 operates.

Meanwhile, according to some embodiments of the present disclosure, the controller 18 may control the vent hole 111 and the exhaust fan 162 based on the user's puff event while smoking. However, the specific control method may be various.

In some examples, the controller 18 may adjust the degree of opening and closing of the vent hole 111 based on the puff event. Specifically, the control unit 18 may open the vent hole 111 more during puffing and less open the vent hole 111 during non-puffing. In this case, outside air flows more smoothly during puff, so that combustion of the smoking article 30 can be further promoted. In addition, the problem of leaking of unpurified sidestream smoke through the vent hole 111 during non-puffing can be alleviated. For reference, since a lot of sidestream smoke is not generated during puffing and an airflow path through which gas flows through the vent hole 111 is formed, a problem of sidestream smoke leaking may not occur even if the vent hole 111 is opened.

In some other examples, the controller 18 may operate (rotate) the exhaust fan 162 in a reverse direction during puffing and may operate (rotate) the exhaust fan 162 in a forward direction during non-puff. Here, the forward direction may mean a rotational direction in which the sidestream smoke is sucked toward the filter structure 161 , and the reverse direction may mean an opposite rotational direction. In this case, when puffing, the airflow is concentrated toward the upstream end of the smoking article 30 to promote combustion, and during non-puffing, sidestream smoke is sucked in the direction of the filter structure 161 so that the sidestream smoke can be smoothly exhausted.

In some other examples, the controller 18 may control the degree of opening and closing of the vent hole 111 and/or the rotational speed of the exhaust fan 162 based on information about the puff event (e.g. puff strength, puff interval, puff length, etc.) can be adjusted. For example, when the strength of the puff increases, the length of the puff increases, or the interval between the puffs decreases, the control unit 18 may further open the vent hole 111 . In the opposite case, the control unit 18 may open the vent hole 111 less. This is because the puff strength is highly likely to increase when the smoking article 30 is not smoothly burned. Alternatively, when the puff intensity is increased, the puff length is increased, or the puff interval is shortened, the control unit 18 may increase the rotation speed of the exhaust fan 162 (ie, the rotation speed in the reverse direction) during puffing. . In the opposite case, the controller 18 may reduce the rotation speed of the exhaust fan 162 .

In some other examples, the control unit 18 may perform control based on a combination of the above-described examples.

In the above embodiments, the method in which the control unit 18 detects the puff may be various. For example, the controller 18 may detect the puff based on a change in temperature measured by the temperature sensor 20 . Specifically, when the degree of temperature change is equal to or greater than the reference value (e.g., when the combustion temperature of the smoking article 30 instantaneously increases), the controller 18 may recognize that the puff has occurred. This may be understood as using a phenomenon in which combustion is accelerated at the upstream end of the smoking article 30 during puffing. Also, the control unit 18 may determine the puff strength based on the degree of temperature change. For example, the controller 18 may determine that the greater the degree of temperature change, the stronger the puff strength, and the smaller the temperature change, the weaker the puff strength is.

In step S30, the control unit 18 may detect the end of smoking. In this step, the manner in which the control unit 18 detects the end of smoking may vary, which may vary according to embodiments.

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

In some other embodiments, the control unit 18 may detect the end of smoking based on the elapsed time since the start of smoking, a puff event, or the like. For example, the controller 18 may determine that smoking has ended when a certain period of time has elapsed from the start of smoking, when the number of puffs is equal to or greater than a reference value, or when puffs are not sensed for more than a certain period of time after a recent puff.

In some other embodiments, a smoking termination condition may be set. For example, the smoking cessation condition may be set based on the number of puffs and the elapsed time of smoking. In this case, the control unit 18 may determine quitting smoking in response to the preset smoking termination condition being satisfied.

In step S40, in response to the detection of smoking cessation, the control unit 18 may perform an automatic fire extinguishing function. In this step, there may be various ways in which the control unit 18 performs the automatic fire extinguishing function.

In some embodiments, the controller 18 may close the vent hole 111 and stop the operation of the exhaust fan 162 . In this case, since the inflow of outside air is stopped by closing the vent hole 111 , the smoking article 30 can be naturally digested due to lack of oxygen.

In some other embodiments, the controller 18 may close the vent hole 111 and stop or continuously operate the exhaust fan 162 after operating for a predetermined time. In this case, the inflow of outside air is stopped by closing the vent hole 111 , and the inside air is exhausted to the outside through the exhaust fan 162 , so that the smoking article 30 can be naturally extinguished.

In some other embodiments, the control unit 18 may also perform an automatic fire extinguishing function by operating the cutting unit 23 .

In some other embodiments, the control unit 18 may perform an automatic fire extinguishing function based on a combination of the above-described embodiments. For example, the control unit 18 may include a first fire extinguishing process for closing the vent hole 111 and stopping the operation of the exhaust fan 162 , and a second fire extinguishing process for cutting the inserted smoking article 30 through the cutting unit 23 . It is also possible to perform an automatic fire extinguishing function through In this case, the first fire extinguishing process and the second fire extinguishing process may be performed irrespective of the order.

Meanwhile, according to some embodiments of the present disclosure, the controller 18 may operate the exhaust fan 162 in the forward direction (ie, in the sucking direction) for a predetermined time in response to detecting the end of smoking. In this case, smoking by-products such as tobacco ash are collected near the filter structure 161 by the exhaust fan 162 , so that the internal cleaning of the sidestream smoke removal device 1 can be made more easily. In some examples, the controller 18 may adjust the rotation speed of the exhaust fan 162 based on the degree of exhaustion of the smoking article 30 . For example, since there will be more by-products when the smoking article 30 is completely exhausted, the controller 18 may rotate the exhaust fan 162 faster, and vice versa. The degree of exhaustion of the smoking article 30 may be determined based on the number of puffs, the elapsed smoking time, the current smoking position (refer to FIG. 13 ), and the like.

So far, a control method according to some embodiments of the present disclosure has been described with reference to FIG. 11 . According to the above-described method, the vent hole 111 and the exhaust fan 162 can be appropriately controlled according to the smoking progress, so that the user's satisfaction with the device can be improved. In addition, since the automatic fire extinguishing function is performed when smoking is finished, the risk of fire and burns due to the user's carelessness can be minimized.

Hereinafter, a control method according to some other embodiments of the present disclosure will be described with reference to FIG. 12 . However, for clarity of the present disclosure, a description of the content overlapping with the control method illustrated in FIG. 11 will be omitted.

12 is an exemplary flowchart illustrating a control method according to some other embodiments of the present disclosure. However, this is only a preferred embodiment for achieving the purpose of the present disclosure, and it goes without saying that some steps may be added or deleted as needed.

12 , the control method may be started in step S110 of detecting the start of smoking. In this step, the control unit 18 may display an indication indicating the start of smoking through the display unit 19 . For further explanation of this step, refer to step S10 illustrated in FIG. 11 .

In step S120, the control unit 18 may monitor the smoking progress. Here, the smoking progress status may include all smoking-related situations, such as a smoking progress level and a puff event.

In some embodiments, the controller 18 accurately determines the smoking progress (or current smoking (burning) position) of the smoking article 30 by comparing the measured temperatures of the plurality of temperature sensors 20 disposed at different positions. can judge Specifically, as shown in FIG. 13 , it is assumed that a plurality of temperature sensors 20 - 1 , 20 - 2 , and 20 - 3 are disposed in the smoking space inside the sidestream smoke removal device 1 in the longitudinal direction. Then, the control unit 18 compares the measured temperatures of the first temperature sensor 20-1, the second temperature sensor 20-2, and the third temperature sensor 20-3, and the current smoking of the smoking article 30 is performed. Location and smoking progress can be determined. For example, 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 third temperature sensor 20- When the measured temperature of 3) is the highest, the controller 18 determines that the current smoking position of the smoking article 30 is between the second temperature sensor 20-2 and the third temperature sensor 20-3, and 3 It can be determined that it is closer to the temperature sensor 20-3. At this time, the controller 18 may determine that the greater the temperature difference between the second temperature sensor 20-2 and the third temperature sensor 20-3, the closer to the third temperature sensor 20-3.

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

In some embodiments, the control unit 18 may display information on the smoking progress through the display unit 19 . For example, the control unit 18 displays a display (e.g. a cigarette-shaped object) indicating the smoking article 30 (or the smoking progress), but the display unit 19 so that the length of the display decreases as smoking progresses. ) can be controlled. As another example, the control unit 18 displays a display area (e.g. LED lighting area/section) indicating the degree of smoking progress through the display unit 19, but as smoking progresses, the size of the display area (e.g. LED lighting area) /number of sections) may be controlled to change the display unit 19 . In this case, as smoking progresses, the size of the display area may increase or decrease.

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, in response to detecting the puff, the control unit 18 may display an indication indicating that the puff is in progress.

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 explanation of this step, refer to step S40 illustrated in FIG. 11 .

On the other hand, when the end of smoking is detected, the control unit 18 performs an automatic fire extinguishing function, and may display an indication indicating automatic fire extinguishing through the display unit 19, or when automatic fire extinguishing is completed, an indication indicating automatic fire extinguishing completion may be displayed.

So far, a control method according to some other embodiments of the present disclosure has been described with reference to FIGS. 12 and 13 . According to the above-described method, information on smoking progress may be displayed through the display unit 19 . Accordingly, the user can check the smoking progress through the display unit 19 in real time, so that the convenience of use of the sidestream smoke removal device 1 can be greatly improved.
