Description

Technical Field

[0001] The invention belongs to the technical field of smoking articles, and in particular relates to a smoking article with adjustable inhalation resistance. Background Art

[0002] As people pay more and more attention to health, they realize that traditional cigarettes are harmful to health. Therefore, new low-hazard tobacco products have developed rapidly in recent years. Heating the smoking matrix at a lower temperature than when it is burned so that the smoking matrix produces releases for users to inhale is an important part of new tobacco products.

[0003] During actual use of existing smoking devices, the smoke-generating substance is directly connected to the atmospheric environment through the air inlet cavity. This method is conducive to the gas quickly penetrating the cigarette core to entrain the substance therein, but it will make the gas penetrate the cigarette core faster, resulting in more substance entrained by the gas in the first half of smoking (the first few puffs), and the amount of smoke is relatively sufficient. However, in the second half of smoking (the last few puffs), the smoke-generating agent in the cigarette core is consumed, resulting in insufficient smoke.

[0004] That is, the amount of substance that enters the user's mouth after the smoking substance is released is much greater in the first half of the puff than in the second half. There is a huge difference between the two, which makes the amount of substance absorbed by the user after the smoking substance is released unstable from puff to puff. Summary of the invention

[0005] The purpose of the present invention is to provide a smoking device with adjustable inhalation resistance, so as to solve the problem of unstable amount of smoke-generating substance inhaled by users after each puff of the smoke-generating substance is released due to structural defects of existing smoking devices.

[0006] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: A smoking device with adjustable inhalation resistance, comprising a body and a controller installed on the body, wherein a heating chamber, an air intake chamber and an installation chamber are arranged in the body; The heating chamber is provided with a heating mechanism for heating the smoking substrate; The air inlet cavity is connected with the heating cavity through the installation cavity; A detection mechanism is installed on the body, and the detection mechanism is used to detect the user's puffing action; The detection mechanism is connected to the controller signal, and the controller is used to receive the detection signal of the detection mechanism; An adjustment mechanism is installed in the installation cavity, and the adjustment mechanism includes a power source and an adjustment member; The controller is connected to the power source signal, and the controller controls the power source to drive the adjustment member to move in the installation cavity; When the adjusting member moves to different positions in the installation cavity, the air intake cavity has different air intake resistances; The controller controls the power source to drive the adjusting member to move according to the suction signal.

[0007] It is further defined that the controller counts the puffing actions based on the detection signal; A correspondence between the number of suction actions and the position of the adjusting member is pre-established; a position corresponding to the number of suction actions is selected from the correspondence as the target position, and the controller controls the power source to drive the adjusting member to move to the target position.

[0008] This structural design controls the power source through a controller, and drives the adjustment part to move to the corresponding position according to the number of suction actions on the smoke-generating substrate detected by the detection mechanism, thereby changing the degree of blocking of the air inlet cavity, thereby changing the suction resistance of the smoking device, thereby changing the air flow rate of the smoke-generating substance part, and then using different air flow rates for each puff and different amounts of smoke-generating substances released for each puff, so that the amount of smoke-generating substance released into the user's mouth remains relatively stable, thereby improving the user experience.

[0009] It is further defined that the detection mechanism is an air resistance sensor disposed on the side wall of the air intake cavity; The air resistance sensor is used to detect the number of times the air resistance inside the air intake cavity changes. When the air resistance changes once, the air resistance sensor sends a preset signal to the controller, and the controller counts once.

[0010] This structural design detects the number of changes in air resistance in the air inlet cavity through an air resistance sensor, and then obtains data on the number of inhalation actions to adjust the inhalation resistance of the smoking device itself. It has a simple structure and strong practicality.

[0011] It is further defined that the detection mechanism is located outside the air inlet cavity.

[0012] Such a structural design, by arranging the detection mechanism outside the air inlet cavity, can avoid the problem that the existence of the detection mechanism itself affects the air intake of the air inlet cavity when the detection mechanism is arranged inside the air inlet cavity, and is highly practical.

[0013] It is further defined that the detection mechanism is a first rangefinder, and the first rangefinder is installed on a side of the body close to the suction end; The first distance meter is used to detect the distance between the main body and the obstacle. When the distance is less than a first set value, the first distance meter sends a preset signal to the controller, and the controller counts once.

[0014] Such a structural design detects the distance between the smoking device and an obstacle (such as the user's face) through the first rangefinder to complete the determination of the inhalation action. It has a simple structure, is easy to install, and is highly practical.

[0015] It is further defined that the detection mechanism is a gyroscope, and the gyroscope is mounted on the body; When the gyroscope detects that the body is converted from a horizontal state to a vertical state, the gyroscope sends a preset signal to the controller, and the controller counts once; The horizontal state is a state in which the angle between the central axis of the body and the horizontal plane is less than α, and the vertical state is a state in which the angle between the central axis of the body and the horizontal plane is greater than β; The 0°≤α≤β≤90°.

[0016] With this structural design, the smoking device is generally in a horizontal state when inhaling, that is, the angle between the central axis of the main body and the horizontal plane is less than α, and is generally in a vertical state after one puff action is completed, that is, the angle between the central axis of the main body and the horizontal plane is greater than β. A gyroscope is used as a detection mechanism to detect the posture of the smoking device. When it is detected that the smoking device is converted from a horizontal state to a vertical state, that is, the angle between the main body of the smoking device and the horizontal plane is converted from less than α to greater than β, the controller counts once, thereby achieving the purpose of detecting the puff action.

[0017] It is further defined that the detection mechanism is a gyroscope, and the gyroscope is mounted on the body; When the gyroscope detects that the body is converted from a vertical state to a horizontal state, the gyroscope sends a preset signal to the controller, and the controller counts once; The horizontal state is a state in which the angle between the central axis of the body and the horizontal plane is less than α, and the vertical state is a state in which the angle between the central axis of the body and the horizontal plane is greater than β; The 0°≤α≤β≤90°.

[0018] With this structural design, the smoking device is generally in a horizontal state when inhaling, that is, the angle between the central axis of the main body and the horizontal plane is less than α, and is generally in a vertical state after one puff is completed, that is, the angle between the central axis of the main body and the horizontal plane is greater than β. A gyroscope is used as a detection mechanism to detect the posture of the smoking device. When it is detected that the smoking device is converted from a vertical state to a horizontal state, that is, the angle between the main body of the smoking device and the horizontal plane is converted from a state greater than β to a state less than α, the controller counts once, thereby achieving the purpose of detecting the puff action.

[0019] It is further defined that α=β=45°.

[0020] Such a structural design, by setting both α and β to 45°, distinguishes two different states at the critical point of 45°, has a simple structure and is easy to control.

[0021] It is further defined that: α=20°, and β=70°.

[0022] This structural design, by setting α and β to two different values ​​and reserving a blank interval between α and β, can reduce the problem of controller error counting caused by external force on the smoking device or improper operation by the user, and is more practical.

[0023] It is further defined that the detection mechanism is a button mounted on the body; When the user takes a puff, the button is pressed once, and the button sends a preset signal to the controller, and the controller counts once.

[0024] Such a structural design can directly count the suction actions manually by pressing a button, has a simple structure, low manufacturing cost and strong practicality.

[0025] It is further defined that the main body is provided with a connection portion that contacts the user's lips, and the detection mechanism is installed on the connection portion.

[0026] The detection mechanism is a second rangefinder, and the second rangefinder is installed on the peripheral side of the connecting part; The second distance meter is used to detect the distance between the connection part and the obstacle. When the distance is less than a second set value, the second distance meter sends a preset signal to the controller, and the controller counts once.

[0027] With this structural design, the distance between the connecting part and the obstacle (such as the lips of the user) is detected by the second rangefinder to complete the determination of the suction action. It has a simple structure, is easy to install, and is highly practical.

[0028] It is further defined that the detection mechanism is a touch sensor, and the touch sensor is mounted on the connecting portion; The touch sensor is used to detect the lips of the user. When the touch sensor is touched, the touch sensor sends a preset signal to the controller, and the controller counts once.

[0029] With this structural design, the user's lips are detected by the touch sensor. When the touch sensor is touched by the user's lips, it is counted once, thereby completing the determination of the suction action.

[0030] It is further defined that the detection mechanism is a first temperature sensor, and the first temperature sensor is installed on the connecting portion; The first temperature sensor is used to detect the temperature of the object being measured. When the first temperature sensor detects that the temperature is within a preset range representing the temperature of the user's lips, the first temperature sensor sends a preset signal to the controller, and the controller counts once.

[0031] With this structural design, the object to be measured (such as the user's lips) is detected by the first temperature sensor. When the first temperature sensor detects a temperature close to the temperature of the user's lips, it counts once, thereby completing the judgment of the suction action. The structure is simple and practical.

[0032] It is further defined that the detection mechanism is a light receiver, and the light receiver is mounted on the connecting portion; The light receiver is used to detect the light intensity at the location of the connecting part. When the light intensity is less than a preset value, the light receiver sends a preset signal to the controller, and the controller counts once.

[0033] Such a structural design detects the light intensity at the position of the connection part through a light receiver to complete the determination of the suction action. It has a simple structure, is easy to install, and is highly practical.

[0034] It is further defined that a light generator is disposed on the body, and the light generator is used to emit light for reception by the light receiver.

[0035] This structural design uses a light generator to provide supplementary light to the smoking device, thereby avoiding the problem of controller miscounting due to insufficient external light intensity in a dark environment, and is highly practical.

[0036] It is further defined that the number of the detection mechanisms is N and they are evenly arranged around the connecting portion, and N ≥ 2; When all the detection mechanisms send preset signals to the controller at the same time, the controller counts once.

[0037] Such a structural design, through the setting of at least two detection mechanisms, limits the controller to count only when all the detection mechanisms send preset signals at the same time. This can avoid the problem of incorrect counting caused by the connecting part accidentally touching flat objects such as arms during use, and is more practical.

[0038] It is further defined that the number of the detection mechanisms is N and they are evenly arranged around the connecting portion, and N ≥ 3; When N is an even number, when at least N / 2+1 of the detection mechanisms simultaneously send preset signals to the controller, the controller counts once; When N is an odd number, when at least (N-1) / 2+1 of the detection mechanisms send preset signals to the controller at the same time, the controller counts once.

[0039] Such a structural design, through the setting of at least two detection mechanisms, limits the controller to count only when more than half, but not all, of the detection mechanisms send preset signals at the same time. This can avoid the problem of erroneous counting caused by the connecting part accidentally touching flat objects such as arms during use. It can also avoid the problem of being unable to count due to the fact that the connecting part does not contact the user's lips at all circumferential positions during the lip closing process. It is highly practical.

[0040] It is further defined that the detection mechanism is arranged in a ring shape.

[0041] Such a structural design, by arranging the touch sensor and the first temperature sensor in a ring shape on the connecting portion, avoids the problem that the touch sensor or the first temperature sensor cannot come into contact with the user's lips due to angle difference, and is highly practical.

[0042] It is further defined that the connecting portion is a mouthpiece, and the mouthpiece is connected to the heating chamber.

[0043] This structural design uses the cigarette holder directly as a connecting part for the detection mechanism to install, and the cigarette holder is reused for a second time, which is very practical.

[0044] It is further defined that the connecting portion is a protrusion arranged on one side of the suction end of the body.

[0045] Such a structural design, by setting a protrusion as the installation position of the detection mechanism, ensures that when the smoking device that heats the heat-not-burn cigarette with its own filter is used, the user's lips do not directly contact the body of the smoking device, but directly contact the filter of the heat-not-burn cigarette, so that the detection mechanism can contact the user's lips and then complete the detection, which is highly practical.

[0046] It is further defined that the connecting portion is a cigarette holder, and the cigarette holder is in communication with the heating chamber; The detection mechanism is a second temperature sensor, and the second temperature sensor is installed inside the cigarette holder; The second temperature sensor is used to detect the temperature of the smoke inside the cigarette holder. When the second temperature sensor detects that the temperature is within a preset range, the second temperature sensor sends a preset signal to the controller, and the controller counts once.

[0047] This structural design detects the smoke temperature inside the cigarette holder through the second temperature sensor. When the second temperature sensor detects that the temperature is within a preset range, it counts once, thereby completing the judgment of the inhalation action. The structure is simple and practical.

[0048] The detection mechanism is a third temperature sensor on the main body for detecting the temperature of the heating mechanism; When the third temperature sensor detects that the temperature of the heating mechanism is within a preset range, the third temperature sensor sends a preset signal to the controller, and the controller counts once.

[0049] Such a structural design uses the third temperature sensor provided in the smoking device body for controlling the temperature of the heating mechanism as a detection mechanism. When the third temperature sensor detects that the temperature is within a preset range, it counts once, thereby completing the judgment of the inhalation action, and reusing the components of the smoking device itself. It has a simple structure and strong practicality.

[0050] The controller controls the power source to drive the adjusting member to move a specific distance according to the detection signal.

[0051] With such a structural design, the controller directly controls the power source to drive the adjusting member to move a specific distance through the detection signal of the detection mechanism, so as to block the air intake chamber to different degrees. It should be noted that the next blockage is performed based on the previous blockage. For example, a servo motor is used to control the blocking mechanism, and the servo motor drives the adjusting member to block to different degrees.

[0052] The invention adopting the above technical solution has the following advantages: The power source is controlled by a controller, and the adjustment part is driven to move according to the suction action detected by the detection mechanism, so as to change the degree of blocking of the air inlet cavity, thereby changing the suction resistance of the smoking device, thereby changing the air flow rate of the smoke-generating substance part, and then using different air flow rates for each puff and different amounts of smoke-generating substances released for each puff, so that the amount of smoke-generating substance released into the user's mouth remains relatively stable, thereby improving the user experience. DETAILED DESCRIPTION

[0053] The technical solution of the present invention is further described in detail below through specific embodiments, which are not intended to limit the present invention. Embodiment 1:

[0055] The power source is controlled by a controller, and according to the number of suction actions on the smoke-generating substrate detected by the detection mechanism, the adjustment part is driven to move to the corresponding position, thereby changing the degree of blocking of the air inlet cavity, thereby changing the suction resistance of the smoking device, thereby changing the air flow rate of the smoke-generating substance part, and then using different air flow rates for each puff and different amounts of smoke-generating substances released for each puff, the amount of smoke-generating substance released into the user's mouth remains relatively stable, thereby improving the user experience.

[0056] In this embodiment, when in use, the heating mechanism in the heating chamber is used to heat the heating substrate, so that the smoking substrate produces a release substance, and then the user inhales the outside air from the air inlet chamber into the smoking device and mixes with the release substance produced by the smoking substrate for the user to inhale; During use, the detection mechanism detects the user's puffing action, and the controller controls the adjustment member to move in the installation cavity through the power source according to the number of puffing actions detected by the detection mechanism, so that the adjustment member moves to different positions in the installation cavity, thereby making the air intake cavity have different air intake resistances, thereby changing the air flow rate of the smoke-generating substance part, and then by means of different air flow rates for each puff and different amounts of smoke-generating substance released for each puff, the amount of smoke-generating substance released into the user's mouth remains relatively stable, thereby improving the user experience. Embodiment 2:

[0057] The only difference between this embodiment and the first embodiment is that: The detection mechanism is an air resistance sensor arranged on the side wall of the air intake cavity; The air resistance sensor may be a pressure sensor; The pressure sensor is used to detect the number of changes in the air pressure in the air intake chamber. When the air pressure changes once, the pressure sensor sends a preset signal to the controller, and the controller counts once; The air resistance sensor can also be a flow rate sensor; The flow velocity sensor is used to detect the number of flow velocity changes in the air intake chamber. When the flow velocity changes once, the flow velocity sensor sends a preset signal to the controller, and the controller counts once.

[0058] Apart from this, the rest of the structures are the same as those in the first embodiment.

[0059] The air resistance sensor is used to detect the number of changes in the air resistance in the air inlet cavity, and then the data of the number of inhalation actions is obtained to adjust the inhalation resistance of the smoking device itself. The structure is simple and the practicability is strong. Embodiment three:

[0060] The only difference between this embodiment and the second embodiment is that: The detection mechanism is located outside the air intake cavity.

[0061] Apart from this, the rest of the structures are the same as those of the second embodiment.

[0062] By arranging the detection mechanism outside the air inlet cavity, the problem that the existence of the detection mechanism itself affects the air intake of the air inlet cavity due to the way in which the detection mechanism is arranged inside the air inlet cavity can be avoided, and the practicality is strong. Embodiment 4:

[0063] The only difference between this embodiment and the third embodiment is that: The detection mechanism is a first distance meter, and the first distance meter is installed on a side of the body close to the suction end; The first distance meter is used to detect the distance between the main body and the obstacle. When the distance is less than a first set value, the first distance meter sends a preset signal to the controller, and the controller counts once.

[0064] Apart from this, the rest of the structures are the same as those of the third embodiment.

[0065] The first rangefinder is used to detect the distance between the smoking device and an obstacle (such as the user's face) to determine the inhalation action. The structure is simple, the installation is convenient, and the practicability is strong.

[0066] In this embodiment, the first setting value may be 1 cm. Specifically, the first setting value may be set to 1.5 cm, 2 cm, etc. according to the actual situation of the smoking device. During use, the distance between the smoking device and the user's face is small when the user is inhaling, and the distance between the smoking device and the user's face is large during the interval between inhalations; A first rangefinder is used as a detection mechanism to detect the distance between the user's face and the smoking device. When the value detected by the first rangefinder is less than a first set value, that is, when the distance between the smoking device and the user's face is detected to be less than 1 cm, it is determined that the user has taken a puff, and the controller counts once. The controller then controls the movement of the adjustment member in the installation cavity through a power source according to the number of puff actions detected by the detection mechanism, so that the adjustment member moves to different positions in the installation cavity, thereby making the air intake cavity have different air intake resistances, thereby changing the airflow rate of the smoking substance part, and then by means of different airflow rates for each puff and different amounts of smoking substance released for each puff, the amount of smoking substance released into the user's mouth remains relatively stable, thereby improving the user experience. Embodiment five:

[0067] The only difference between this embodiment and the fourth embodiment is that: The detection mechanism is a gyroscope, which is mounted on the body; When the gyroscope detects that the body is converted from a horizontal state to a vertical state, the gyroscope sends a preset signal to the controller, and the controller counts once; The horizontal state is a state in which the angle between the central axis of the body and the horizontal plane is less than α, and the vertical state is a state in which the angle between the central axis of the body and the horizontal plane is greater than β; α=β=45°.

[0068] Apart from this, the rest of the structures are the same as those of the fourth embodiment.

[0069] In this embodiment, during use, based on the characteristics that the user lifts up the smoking device to smoke, so that the smoking device is generally in a horizontal state, and puts down the smoking device in the interval between smoking, so that the smoking device is generally in a vertical state; The gyroscope is used as a detection mechanism to measure the angle between the smoking device and the horizontal plane. When the angle between the smoking device and the horizontal plane is less than 45°, it is determined that the smoking device is in a horizontal state, that is, in a smoking state; When the angle between the smoking device and the horizontal is greater than 45°, the smoking device is judged to be in a vertical state, that is, in the interval of inhalation; Through the situation of converting from the horizontal state to the vertical state in the two determinations, it is determined that the user has taken a puff, and then the controller counts it once. Embodiment six:

[0070] The only difference between this embodiment and the fifth embodiment is that: α=20°, β=70°.

[0071] Apart from this, the rest of the structures are the same as those of the fifth embodiment.

[0072] By setting α and β to two different values ​​and reserving a blank interval between α and β, the problem of controller error counting caused by external force on the smoking device or improper operation by the user can be reduced, which is more practical. Embodiment seven:

[0073] The only difference between this embodiment and the fifth embodiment is that: The detection mechanism is a gyroscope, which is mounted on the body; When the gyroscope detects that the body is converted from a vertical state to a horizontal state, the gyroscope sends a preset signal to the controller, and the controller counts once; The horizontal state is a state in which the angle between the central axis of the body and the horizontal plane is less than α, and the vertical state is a state in which the angle between the central axis of the body and the horizontal plane is greater than β; α=β=45°.

[0074] Apart from this, the rest of the structures are the same as those of the fifth embodiment.

[0075] In this embodiment, during use, based on the characteristics that the user lifts up the smoking device to smoke, so that the smoking device is generally in a horizontal state, and puts down the smoking device in the interval between smoking, so that the smoking device is generally in a vertical state; The gyroscope is used as a detection mechanism to measure the angle between the smoking device and the horizontal plane. When the angle between the smoking device and the horizontal plane is less than 45°, it is determined that the smoking device is in a horizontal state, that is, in a smoking state; When the angle between the smoking device and the horizontal is greater than 45°, the smoking device is judged to be in a vertical state, that is, in the interval of inhalation; Through the case of transitioning from the vertical state to the horizontal state in the two determinations, it is determined that the user has taken a puff, and the controller counts it once. Embodiment eight:

[0076] The only difference between this embodiment and the seventh embodiment is that: α=20°, β=70°.

[0077] Apart from this, the rest of the structures are the same as those of the seventh embodiment.

[0078] By setting α and β to two different values ​​and reserving a blank interval between α and β, the problem of controller error counting caused by external force on the smoking device or improper operation by the user can be reduced, which is more practical. Embodiment nine:

[0079] The only difference between this embodiment and the fourth embodiment is that: The detection mechanism is a button installed on the body; When the user takes a puff, the button is pressed once, and the button sends a preset signal to the controller, which counts once.

[0080] Apart from this, the rest of the structures are the same as those of the fourth embodiment.

[0081] By pressing a button, the suction action can be directly counted manually, the structure is simple, the manufacturing cost is low, and the practicability is strong.

[0082] In this embodiment, during use, the button is pressed once each time the user takes a puff, and it is determined that the user has taken a puff, which is then counted by the controller. Embodiment ten:

[0083] The only difference between this embodiment and the fourth embodiment is that: The main body is provided with a connecting part contacting with the lips of the user, and the detection mechanism is installed on the connecting part.

[0084] The detection mechanism is a second distance meter, and the second distance meter is installed on the peripheral side of the connecting part; The second distance meter is used to detect the distance between the connecting part and the obstacle. When the distance is less than a second set value, the second distance meter sends a preset signal to the controller, and the controller counts once.

[0085] Apart from this, the rest of the structures are the same as those of the fourth embodiment.

[0086] In this embodiment, the second setting value may be 0. Specifically, the second setting value may be set to a specific value of 0.1 cm, 0.2 cm, etc. according to the actual situation of the smoking device itself; During use, based on the contact between the user's lips and the connecting portion when the user draws, and the distance between the smoking device and the user's lips is relatively large during the interval between draws; The second rangefinder is used as a detection mechanism to detect the distance between the user's lips and the smoking device. When the value detected by the second rangefinder is less than the second set value, that is, when the distance between the position of the smoking device and the user's lips is detected to be 0, it is determined that the user has inhaled once, and the controller counts it once.

[0087] Embodiment eleven: The only difference between this embodiment and the tenth embodiment is that: There are N second rangefinders, which are evenly arranged around the connecting portion, N≥2; preferably N is 2; When all the second rangefinders send the preset signal to the controller at the same time, the controller counts once.

[0088] Apart from this, the rest of the structures are the same as those of the tenth embodiment.

[0089] In fact, according to actual conditions, only one second rangefinder may be provided. In this embodiment, at least two second rangefinders are provided, and the controller is limited to count only when all the second rangefinders send preset signals at the same time, that is, when multiple second rangefinders simultaneously detect that the distance to the lips is 0. This can avoid the problem of erroneous counting caused by the connection part accidentally touching a flat object such as an arm during use, and is more practical.

[0090] Embodiment 12: The only difference between this embodiment and the eleventh embodiment is that: There are N detection mechanisms, which are evenly arranged around the connecting portion, N≥3; preferably N is 3; When N is an even number, the controller counts once when at least N / 2+1 detection mechanisms send preset signals to the controller at the same time; When N is an odd number, the controller counts once when at least (N-1) / 2+1 detection mechanisms send preset signals to the controller at the same time.

[0091] Apart from this, the rest of the structures are the same as those of the eleventh embodiment.

[0092] In fact, according to actual conditions, on the basis of setting up multiple second rangefinders, it is also possible to set the controller to count once after another number of second rangefinders are triggered. This embodiment is set up by at least two detection mechanisms, and limits the controller to count only when more than half, but not all, of the detection mechanisms send preset signals at the same time. This can avoid the problem of erroneous counting caused by the connecting part accidentally touching a flat object such as an arm during use, and also avoid the problem of being unable to count due to the fact that not all circumferential positions of the connecting part are in contact with the user's lips during lip closing. This has strong practicality.

[0093] Embodiment 13: The only difference between this embodiment and the tenth embodiment is that: The connecting part is a cigarette holder, which is communicated with the heating chamber.

[0094] Apart from this, the rest of the structures are the same as those of the tenth embodiment.

[0095] The cigarette holder is directly used as a connecting part for installation by the detection mechanism, and the cigarette holder is reused for a second time, which is highly practical.

[0096] Embodiment 14: The only difference between this embodiment and the thirteenth embodiment is that: The connecting portion is a protrusion arranged on one side of the suction end of the body.

[0097] Apart from this, the rest of the structures are the same as those of the thirteenth embodiment.

[0098] By providing a protrusion as the installation position of the detection mechanism, when using the smoking device for heating the heat-not-burn cigarette with its own filter, the user's lips do not directly contact the body of the smoking device, but directly contact the filter of the heat-not-burn cigarette, so that the detection mechanism can contact the user's lips and then complete the detection, which is more practical.

[0099] Embodiment 15: The only difference between this embodiment and the tenth embodiment is that: The detection mechanism is a touch sensor, and the touch sensor is installed on the connecting part; The touch sensor is used to detect the lips of the user. When the touch sensor is touched, the touch sensor sends a preset signal to the controller, and the controller counts once.

[0100] Apart from this, the rest of the structures are the same as those of the tenth embodiment.

[0101] The user's lips are detected by the touch sensor. When the touch sensor is touched by the user's lips, it is counted once, thereby completing the determination of the suction action.

[0102] In this embodiment, during use, based on the contact between the user's lips and the connecting portion when the user draws, and the smoking device is out of contact with the user's lips during the interval between draws; The touch sensor is used as a detection mechanism to detect the contact between the user's lips and the smoking device. When the touch sensor is touched by the user's lips, it is determined that the user has inhaled once, and then the controller counts it once.

[0103] Embodiment 16: The only difference between this embodiment and the fifteenth embodiment is that: There are N touch sensors, which are evenly arranged around the connecting portion, N≥2; preferably N is 2; When all touch sensors send preset signals to the controller at the same time, the controller counts once.

[0104] Apart from this, the rest of the structures are the same as those of the fifteenth embodiment.

[0105] In fact, according to actual conditions, only one touch sensor may be provided. In this embodiment, at least two touch sensors are provided, and the controller is limited to count only when all touch sensors send preset signals at the same time, that is, when multiple touch sensors simultaneously detect that the distance to the lips is 0. This can avoid the problem of incorrect counting caused by the connecting part accidentally touching a flat object such as an arm during use, and is more practical.

[0106] Embodiment 17: The only difference between this embodiment and the fifteenth embodiment is that: There are N detection mechanisms, which are evenly arranged around the connecting portion, N≥3; preferably N is 3; When N is an even number, the controller counts once when at least N / 2+1 detection mechanisms send preset signals to the controller at the same time; When N is an odd number, the controller counts once when at least (N-1) / 2+1 detection mechanisms send preset signals to the controller at the same time.

[0107] Apart from this, the rest of the structures are the same as those of the fifteenth embodiment.

[0108] In fact, according to actual conditions, on the basis of setting up multiple touch sensors, it is also possible to set the controller to count once after another number of touch sensors are triggered. This embodiment is set up by at least two detection mechanisms, and limits the controller to count only when more than half, but not all, of the detection mechanisms send preset signals at the same time. This can avoid the problem of incorrect counting caused by the connecting part accidentally touching flat objects such as arms during use, and also avoid the problem of being unable to count due to the fact that not all circumferential positions of the connecting part are in contact with the user's lips during lip closing. This has strong practicality.

[0109] Embodiment 18: The only difference between this embodiment and the fifteenth embodiment is that: The detection mechanism is arranged in a ring shape.

[0110] Apart from this, the rest of the structures are the same as those of the fifteenth embodiment.

[0111] By arranging the touch sensor and the first temperature sensor in a ring shape on the connecting portion, the problem that the touch sensor or the first temperature sensor cannot come into contact with the user's lips due to angle difference can be avoided, and the practicability is strong.

[0112] Embodiment 19: The only difference between this embodiment and the fifteenth embodiment is that: The connecting part is a cigarette holder, which is communicated with the heating chamber.

[0116] Apart from this, the rest of the structures are the same as those of the nineteenth embodiment.

[0117] By providing a protrusion as the installation position of the detection mechanism, when using the smoking device for heating the heat-not-burn cigarette with its own filter, the user's lips do not directly contact the body of the smoking device, but directly contact the filter of the heat-not-burn cigarette, so that the detection mechanism can contact the user's lips and then complete the detection, which is more practical.

[0118] Embodiment 21: The only difference between this embodiment and the fifteenth embodiment is that: The detection mechanism is a light receiver, and the light receiver is installed on the connecting part; The light receiver is used to detect the light intensity at the location of the connection part. When the light intensity is less than a preset value, the light receiver sends a preset signal to the controller, and the controller counts once.

[0119] Apart from this, the rest of the structures are the same as those of the fifteenth embodiment.

[0120] The light intensity at the position of the connection part is detected by a light receiver to complete the determination of the suction action. The structure is simple, the installation is convenient, and the practicability is strong.

[0121] In this embodiment, during use, when the user draws, the user's lips contact the connecting portion, which shields the connecting portion, so that the light intensity at the location of the connecting portion becomes weaker, and in the interval between draws, the smoking device is out of contact with the user's lips; A light receiver is used as a detection mechanism to detect the contact between the user's lips and the smoking device. When the light receiver is touched by the user's lips, the light received by the light receiver becomes weaker. This indicator is used to determine that the user has taken a puff, and the controller then counts it once.

[0122] Embodiment 22: The only difference between this embodiment and the twenty-first embodiment is that: There are N light receivers, which are evenly arranged around the connecting portion, N≥2; preferably N is 2; When all the light receivers send the preset signal to the controller at the same time, the controller counts once.

[0123] Apart from this, the rest of the structures are the same as those of Example 21.

[0124] In fact, according to actual conditions, only one light receiver may be provided. In this embodiment, at least two light receivers are provided, and the controller is limited to count only when all light receivers send preset signals at the same time, that is, when multiple light receivers simultaneously detect that the distance to the lips is 0. This can avoid the problem of erroneous counting caused by the connecting part accidentally touching a flat object such as an arm during use, and is more practical.

[0125] Embodiment 23: The only difference between this embodiment and the twenty-second embodiment is that: There are N detection mechanisms, which are evenly arranged around the connecting portion, N≥3; preferably N is 3; When N is an even number, the controller counts once when at least N / 2+1 detection mechanisms send preset signals to the controller at the same time; When N is an odd number, the controller counts once when at least (N-1) / 2+1 detection mechanisms send preset signals to the controller at the same time.

[0126] Apart from this, the rest of the structures are the same as those of Example 22.

[0127] In fact, according to actual conditions, on the basis of setting up multiple light receivers, it is also possible to set the controller to count once after another number of light receivers are triggered. This embodiment is set up by at least two detection mechanisms, and limits the controller to count only when more than half, but not all, of the detection mechanisms send preset signals at the same time. This can avoid the problem of erroneous counting caused by the connecting part accidentally touching a flat object such as an arm during use, and also avoid the problem of being unable to count due to the fact that not all circumferential positions of the connecting part are in contact with the user's lips during lip closing. This has strong practicality.

[0128] Embodiment 24: The only difference between this embodiment and the twenty-second embodiment is that: The main body is provided with a light generator, which is used for emitting light for the light receiver to receive.

[0129] Apart from this, the rest of the structures are the same as those of Example 22.

[0130] The light generator is used to supplement the lighting of the smoking device to avoid the problem of controller miscounting due to insufficient external light intensity in a dark environment, which is very practical.

[0135] Apart from this, the rest of the structures are the same as those of Example 25.

[0136] By providing a protrusion as the installation position of the detection mechanism, when using the smoking device for heating the heat-not-burn cigarette with its own filter, the user's lips do not directly contact the body of the smoking device, but directly contact the filter of the heat-not-burn cigarette. This allows the detection mechanism to contact the user's lips, and then the lips block the light received on the protrusion, thereby completing the detection, which is more practical.

[0137] Embodiment 27: The only difference between this embodiment and the fifteenth embodiment is that: The detection mechanism is a first temperature sensor, and the first temperature sensor is installed on the connecting part; The first temperature sensor is used to detect the temperature of the object being measured.

[0139] The object to be measured (such as the lips of the user) is detected by the first temperature sensor. When the first temperature sensor detects a temperature close to the temperature of the lips of the user, it counts once, thereby completing the judgment of the suction action. The structure is simple and the practicability is strong.

[0140] In this embodiment, during use, due to the contact between the user's lips and the connecting portion when the user draws, the temperature of the user's lips is different from the outside temperature, and during the interval between draws, the smoking device is out of contact with the user's lips; The first temperature sensor is used as a detection mechanism to detect the external temperature. When the first temperature sensor is touched by the user's lips and the temperature detected by the first temperature sensor is within a preset range of the user's lip temperature, it is determined that the user has inhaled once, and the controller counts once.

[0146] In fact, according to actual conditions, on the basis of setting multiple first temperature sensors, it is also possible to set the controller to count once after another number of first temperature sensors are triggered. This embodiment is set by at least two detection mechanisms, and limits the controller to count only when more than half, but not all, of the detection mechanisms send preset signals at the same time. This can avoid the problem of incorrect counting caused by the connecting part accidentally touching flat objects such as arms during use, and the problem of being unable to count due to the fact that not all circumferential positions of the connecting part are in contact with the user's lips during lip closing. It is very practical.

[0148] Apart from this, the rest of the structures are the same as those of Example 28.

[0149] By arranging the touch sensor and the first temperature sensor in a ring shape on the connecting portion, the problem that the touch sensor or the first temperature sensor cannot come into contact with the user's lips due to angle difference can be avoided, and the practicability is strong.

[0150] Embodiment 31: The only difference between this embodiment and the twenty-seventh embodiment is that: The connecting part is a cigarette holder, which is communicated with the heating chamber.

[0154] Apart from this, the rest of the structures are the same as those of Example 31.

[0155] By providing a protrusion as the installation position of the detection mechanism, when using the smoking device for heating the heat-not-burn cigarette with its own filter, the user's lips do not directly contact the body of the smoking device, but directly contact the filter of the heat-not-burn cigarette. This allows the detection mechanism to contact the user's lips and then monitor the temperature of the lips, thereby completing the detection, which is more practical.

[0156] Embodiment 33: The only difference between this embodiment and the tenth embodiment is that: The connecting part is a cigarette holder, which is connected with the heating chamber; The detection mechanism is a second temperature sensor, and the second temperature sensor is installed inside the cigarette holder; The second temperature sensor is used for the temperature of the smoke inside the cigarette holder. When the second temperature sensor detects that the temperature is within a preset range, the second temperature sensor sends a preset signal to the controller, and the controller counts once.

[0157] Apart from this, the rest of the structures are the same as those of the tenth embodiment.

[0158] The smoke temperature inside the cigarette holder is detected by the second temperature sensor. When the second temperature sensor detects that the temperature is within a preset range, it counts once, thereby completing the judgment of the inhalation action. The structure is simple and the practicability is strong.

[0159] In this embodiment, during use, based on the characteristics that when the user draws, the smoke heated by the heating mechanism flows through the mouthpiece, the smoke temperature is different from the outside temperature, and the smoke temperature inside the mouthpiece decreases during the interval between draws; The second temperature sensor is used as a detection mechanism to detect the temperature inside the cigarette holder. When smoke flows through the cigarette holder, the temperature detected by the second temperature sensor is within a preset range, and it is determined that the user has taken one puff, which is then counted by the controller.

When the third temperature sensor detects that the temperature is within a preset range, it counts once, thereby completing the judgment of the inhalation action, and reusing the components of the smoking device itself. The structure is simple and the practicability is strong.

[0163] In this embodiment, during use, when the user draws, the heated air in the smoking substrate leaves the heating mechanism, and new unheated air re-enters the smoking substrate, thereby driving the temperature of the heating mechanism to decrease. The third temperature sensor is used as a detection mechanism to detect the temperature of the heating mechanism. When the heated air leaves the heating mechanism, new unheated air re-enters the smoking substrate, causing the temperature of the heating mechanism to drop to within a preset range. The user is judged to have taken one puff, which is then counted by the controller.

[0166] Through the detection signal of the detection mechanism, the controller directly controls the power source to drive the adjusting member to move a specific distance to block the air intake chamber to different degrees. It should be noted that the next blocking is based on the previous blocking. For example, a servo motor is used to control the blocking mechanism, and the servo motor drives the adjusting member to block to different degrees.
