Description

An air suction resistance adjustable smoking set TECHNICAL FIELD

[0001] The present application belongs to the technical field of smoking set, and particularly relates to an air suction resistance adjustable smoking set. BACKGROUND

[0002] With the increasing concern about health, people are aware that traditional cigarettes have certain harm to health, therefore, new tobacco products with low harm have rapidly developed in recent years, and heating the smoking substrate at a lower temperature than combustion to make the smoking substrate release substances for users to smoke is an important part of new tobacco products.

[0003] In the actual use process of the existing smoking set, the smoking material is directly and completely communicated with the atmospheric environment through the air inlet cavity, which is beneficial to the rapid penetration of the gas through the tobacco core to carry out the substances therein, but the speed of the gas penetrating through the tobacco core is relatively fast, resulting in that more substances are carried out by the gas in the first half of the suction (the first few puffs), and the smoking amount is relatively sufficient, but in the second half of the suction (the last few puffs), the smoking agent in the tobacco core is consumed, resulting in insufficient smoking amount.

[0004] That is, the amount of substances entering the user's oral cavity after the release of the smoking material is much greater in the first half of the suction than in the second half of the suction, and there is a great difference between the two, which further makes the amount of substances taken by the user unstable. SUMMARY

[0005] The purpose of the present application is to provide an air suction resistance adjustable smoking set to solve the problem of unstable amount of substances taken by the user in the use of the existing smoking set due to the structural defects of the existing smoking set.

[0006] To achieve the above technical purpose, the technical scheme adopted by the present application is as follows:

[0008] A heating mechanism for heating the smoking substrate is arranged in the heating cavity;

[0009] The air inlet cavity is communicated with the heating cavity through the mounting cavity;

[0010] A detection mechanism is installed on the body, and the detection mechanism is used for detecting the suction action of the user;

[0011] The detection mechanism is signal connected with the controller, and the controller is used for receiving the detection signal of the detection mechanism;

[0012] The installation cavity is provided with an adjusting mechanism, which comprises a power source and an adjusting part;

[0013] The controller is connected with the power source, and the controller controls the power source to drive the adjusting part to move in the installation cavity;

[0014] When the adjusting part moves to different positions in the installation cavity, the air inlet cavity has different air inlet resistances;

[0015] The controller controls the power source to drive the adjusting part to move according to the suction signal.

[0016] Further limited, the controller counts the suction action according to the detection signal;

[0017] The corresponding relationship between the number of suction actions and the position of the adjusting part is established in advance; the position corresponding to the number of suction actions is selected as the target position from the corresponding relationship, and the power source is controlled by the controller to drive the adjusting part to move to the target position.

[0018] Such a structure design, through the controller controls the power source, according to the detection mechanism detects the number of suction actions on the smoking substrate, drives the adjusting part to move to the corresponding position, changes the plugging degree of the air inlet cavity, thereby changes the suction resistance of the smoking set, so as to change the air flow of the part of the smoking material, and then in the way of different air flow of each mouth cooperating with different release amount of smoking material, the release amount of smoking material into the user's oral cavity remains relatively stable, and the user experience is improved.

[0019] Further limited, the detection mechanism is an air resistance sensor arranged on the side wall of the air inlet cavity;

[0020] The air resistance sensor is used to detect the number of air resistance changes in the air inlet cavity, and the air resistance sensor sends a preset signal to the controller when the air resistance changes once, and the controller counts once.

[0021] Such a structure design, through the air resistance sensor detects the number of air resistance changes in the air inlet cavity, and then obtains the data of the number of suction actions, so as to adjust the suction resistance of the smoking set, which is simple in structure and high in practicability.

[0022] Further limited, the detection mechanism is located outside the air inlet cavity.

[0023] Such a structure design, by setting the detection mechanism outside the air inlet cavity, can avoid the problem that the existence of the detection mechanism itself affects the air inlet of the air inlet cavity when the detection mechanism is arranged in the air inlet cavity, which is high in practicability.

[0024] Further limited, the detection mechanism is a first distance meter, and the first distance meter is installed on one side of the body close to the suction end;

[0025] The first distance meter is used for detecting the distance size between the body and the obstacle, and when the distance size is less than a first set value, the first distance meter sends a preset signal to the controller, and the controller counts once.

[0026] Such a structure design detects the distance between the smoking set and the obstacle (such as the user's face) through the first distance meter, completes the determination of the smoking action, has simple structure, is convenient to install, and has strong practicability.

[0027] Further limitation, the detection mechanism is a gyroscope, and the gyroscope is installed on the body.

[0028] 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.

[0029] The horizontal state is a state in which the included 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 included angle between the central axis of the body and the horizontal plane is greater than β.

[0030] The 0°≤α≤β≤90°.

[0031] Such a structure design, when the smoking set is smoked, is generally in a horizontal state, that is, the included angle between the central axis of the body and the horizontal plane is less than α, and after a smoking action is completed, is generally in a vertical state, that is, the included angle between the central axis of the body and the horizontal plane is greater than β. The gyroscope is used as a detection mechanism to detect the posture of the smoking set. When it is detected that the smoking set is converted from a horizontal state to a vertical state, that is, the included angle between the body of the smoking set and the horizontal plane is converted from a state of being less than α to a state of being greater than β, the controller counts once, thereby achieving the purpose of detecting the smoking action.

[0032] Further limitation, the detection mechanism is a gyroscope, and the gyroscope is installed on the body.

[0033] 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.

[0034] The horizontal state is a state in which the included 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 included angle between the central axis of the body and the horizontal plane is greater than β.

[0035] The 0°≤α≤β≤90°.

[0036] The structure is designed such that the smoking set is in a horizontal state when being smoked, i.e., the angle between the central axis of the body and the horizontal plane is less than α, and is in a vertical state after a smoking action is completed, i.e., the angle between the central axis of the body and the horizontal plane is greater than β. The posture of the smoking set is detected by using a gyroscope as a detection mechanism. When the smoking set is detected to be converted from the vertical state to the horizontal state, i.e., the angle between the body of the smoking set and the horizontal plane is converted from greater than β to less than α, the controller counts once, thereby achieving the purpose of detecting the smoking action.

[0037] It is further limited that α=β=45°.

[0038] The structure is designed such that α and β are both set to 45°, and the critical point of 45° is used to distinguish the two different states, so that the structure is simple and the control is convenient.

[0039] It is further limited that α=20° and β=70°.

[0040] The structure is designed such that α and β are set to two different values, and a blank interval is reserved between α and β, so as to reduce the problem of incorrect counting of the controller caused by the smoking set being rocked by external force or improper operation of the user, and the practicability is high.

[0041] It is further limited that the detection mechanism is a button installed on the body.

[0042] When the user smokes once, the button is pressed once, the button sends a preset signal to the controller, and the controller counts once.

[0043] The structure is designed such that the smoking action is directly counted manually by pressing the button, so that the structure is simple, the manufacturing cost is low, and the practicability is high.

[0044] It is further limited that the body is provided with a connecting portion in contact with the lips of the user, and the detection mechanism is installed on the connecting portion.

[0045] The detection mechanism is a second distance meter, and the second distance meter is installed on the periphery of the connecting portion.

[0046] The second distance meter is used to detect the distance between the connecting portion and an obstacle, and 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.

[0047] The structure is designed such that the distance between the connecting portion and the obstacle (such as the lips of the user) is detected by the second distance meter, and the smoking action is determined, so that the structure is simple, the installation is convenient, and the practicability is high.

[0048] Further limited, the detection mechanism is a touch sensor, the touch sensor is installed on the connecting part;

[0049] The touch sensor is used for detecting 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.

[0050] Such a structure design, through the touch sensor to the user's lips are detected, when the touch sensor is touched by the user's lips, count once, and then complete the determination of the suction action.

[0051] Further limited, the detection mechanism is a first temperature sensor, the first temperature sensor is installed on the connecting part;

[0052] The first temperature sensor is used for detecting the temperature of the measured object, when the first temperature sensor detects that the temperature is in 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.

[0053] Such a structure design, through the first temperature sensor to the measured object (such as the user's lips) are detected, when the first temperature sensor detects that the temperature is close to the temperature of the user's lips, count once, and then complete the determination of the suction action, simple structure, strong practicability.

[0054] Further limited, the detection mechanism is a light receiver, the light receiver is installed on the connecting part;

[0055] The light receiver is used for detecting the light intensity of the position where the connecting part is located, 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.

[0056] Such a structure design, through the light receiver to the light intensity of the position where the connecting part is located, complete the determination of the suction action, simple structure, easy to install, strong practicability.

[0057] Further limited, the body is provided with a light generator, the light generator is used for emitting light for the light receiver to receive.

[0058] Such a structure design, through the light generator to the light operation of the smoking set, avoid in the dark environment, because the external light intensity is insufficient, and lead to the problem of controller error count, strong practicability.

[0059] Further limited, the detection mechanism is N, and is uniformly arranged on the circumferential side of the connecting part, N≥2;

[0060] When all the detection mechanisms send a preset signal to the controller at the same time, the controller counts once.

[0061] Such a structure design, through the setting of at least two detection mechanisms, and limiting the controller to count only when all detection mechanisms simultaneously send preset signals, can avoid the problem of false counting caused by the connection part accidentally touching flat objects such as arms during use, and has strong practicality.

[0062] Further limitation, the detection mechanism is N, and is uniformly arranged on the periphery of the connecting part, N≥3;

[0063] When N is even, at least N / 2+1 detection mechanisms simultaneously send preset signals to the controller, and the controller counts once;

[0064] When N is odd, at least (N-1) / 2+1 detection mechanisms simultaneously send preset signals to the controller, and the controller counts once.

[0065] Such a structure design, through the setting of at least two detection mechanisms, and limiting the controller to count only when more than half, but not all detection mechanisms simultaneously send preset signals, can avoid the problem of false counting caused by the connection part accidentally touching flat objects such as arms during use, and can also avoid the problem of not being able to count caused by not all positions of the connecting part being in contact with the user's lips during the closing of the lips, and has strong practicality.

[0066] Further limitation, the detection mechanism is arranged in a ring shape.

[0067] Such a structure design, through the ring-shaped arrangement of the touch sensor and the first temperature sensor on the connecting part, can avoid the problem that the touch sensor or the first temperature sensor cannot form contact with the user's lips due to angle differences, and has strong practicality.

[0068] Further limitation, the connecting part is a mouthpiece, and the mouthpiece communicates with the heating cavity.

[0069] Such a structure design, through the mouthpiece directly serving as the connecting part for the installation of the detection mechanism, realizes secondary utilization of the mouthpiece, and has strong practicality.

[0070] Further limitation, the connecting part is a protrusion arranged on one side of the suction end of the body.

[0071] Such a structure design, through the setting of the protrusion as the installation position of the detection mechanism, makes the detection mechanism be able to contact the user's lips and complete detection in the case that the user's lips directly contact the filter of the heat-not-burn cigarette instead of directly contacting the body of the smoking device during the heating of the heat-not-burn cigarette with a built-in filter, and has strong practicality.

[0072] Further specifying, the connecting part is a cigarette holder, and the cigarette holder is in communication with the heating chamber;

[0073] The detection mechanism is a second temperature sensor, which is installed inside the mouthpiece;

[0074] The second temperature sensor is used to measure the temperature of the smoke inside the mouthpiece. 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.

[0075] This structural design uses a second temperature sensor to detect the temperature of the smoke inside the mouthpiece. When the second temperature sensor detects that the temperature is within a preset range, it counts once, thus completing the determination of the suction action. The structure is simple and highly practical.

[0076] The detection mechanism is a third temperature sensor on the main body used to detect the temperature of the heating mechanism;

[0077] 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.

[0078] This structural design utilizes a third temperature sensor built into the smoking device itself to control the temperature of the heating mechanism. When the third temperature sensor detects that the temperature is within a preset range, it counts once, thereby determining the suction action. This design allows for the reuse of components from the smoking device itself, resulting in a simple structure and strong practicality.

[0079] The controller controls the power source to move the adjusting component a specific distance based on the detection signal.

[0080] This structural design allows the controller to directly control the power source to move the adjusting component a specific distance based on the detection signal from the detection mechanism, thereby blocking the air intake chamber to varying degrees. It is important to note that each subsequent blocking operation is based on the previous one. For example, a servo motor can be used to control the blocking mechanism, and the servo motor can drive the adjusting component to block to varying degrees.

[0081] The invention employing the above technical solution has the following advantages:

[0082] The controller controls the power source and, based on the suction action detected by the detection mechanism, drives the adjustment component to change the degree of blockage of the air intake chamber, thereby changing the suction resistance of the smoking device. This changes the airflow rate of the smoke-producing material, and by using different airflow rates for each puff in conjunction with different amounts of smoke-producing material released each puff, the amount of smoke-producing material released into the user's mouth remains relatively stable, thus improving the user experience. DETAILED DESCRIPTION

[0083] The technical solutions of the present application are further described below by specific examples, which are not used to limit the present application.

[0084] Example One:

[0085] The smoking set with adjustable air resistance provided by the present application comprises a body and a controller installed on the body, and the body is internally provided with a heating cavity, an air inlet cavity and a mounting cavity;

[0086] The heating cavity is internally provided with a heating mechanism for heating the smoking substrate;

[0087] The air inlet cavity is communicated with the heating cavity through the mounting cavity;

[0088] The body is installed with a detection mechanism, which is used for detecting the suction action of the user;

[0089] The detection mechanism is signal connected with the controller, and the controller is used for receiving the detection signal of the detection mechanism and counting the suction action;

[0090] The mounting cavity is installed with an adjusting mechanism, and the adjusting mechanism comprises a power source and an adjusting piece;

[0091] The controller is signal connected with the power source, and the controller controls the power source to drive the adjusting piece to move in the mounting cavity;

[0092] When the adjusting piece moves to different positions in the mounting cavity, the air inlet cavity has different air inlet resistance;

[0093] The corresponding relationship between the number of suction actions and the position of the adjusting piece is established in advance; the position corresponding to the number of suction actions is selected as the target position from the corresponding relationship, and the power source is controlled by the controller to drive the adjusting piece to move to the target position.

[0094] The power source is controlled by the controller according to the number of suction actions of the smoking substrate detected by the detection mechanism, and the adjusting piece is driven to move to the corresponding position, so as to change the plugging degree of the air inlet cavity, thereby changing the suction resistance of the smoking set, so as to change the air flow of the smoking substrate part, and then in the way of different air flow for each mouth and different release amount of smoking substrate for each mouth, the release amount of the smoking substrate entering the user's oral cavity is kept relatively stable, and the user experience is improved.

[0095] In this embodiment, when in use, the heating mechanism in the heating cavity is used to heat the heating substrate, so that the smoking substrate generates a release, and then through the suction of the user, the air from the outside is sucked into the smoking set from the air inlet cavity, and is mixed with the release generated by the smoking substrate, for the user to smoke;

[0096] In use, the detection mechanism detects the puffing action of the user, and the controller adjusts the movement of the power source control adjusting piece in the installation cavity according to the number of puffing actions detected by the detection mechanism, so that the adjusting piece moves to different positions in the installation cavity, so that the air inlet cavity has different air inlet resistances, thereby changing the air flow of the smoke generating material part, and then changing the release amount of the smoke generating material into the user's oral cavity in a way of different air flow for each puff, so as to keep the release amount of the smoke generating material into the user's oral cavity relatively stable, and improve the user experience.

[0097] Embodiment two:

[0098] The only difference between this embodiment and embodiment one is that:

[0099] The detection mechanism is an air resistance sensor arranged on the side wall of the air inlet cavity.

[0100] The air resistance sensor can be a pressure sensor.

[0101] The pressure sensor is used to detect the number of times of air pressure changes in the air inlet cavity, and the pressure sensor sends a preset signal to the controller once the air pressure changes, and the controller counts once.

[0102] The air resistance sensor can also be a flow rate sensor.

[0103] The flow rate sensor is used to detect the number of times of flow rate changes in the air inlet cavity, and the flow rate sensor sends a preset signal to the controller once the flow rate changes, and the controller counts once.

[0104] In addition, the rest of the structure is the same as that of embodiment one.

[0105] The number of air resistance changes in the air inlet cavity is detected by the air resistance sensor, and the data of the number of puffing actions is obtained to adjust the suction resistance of the smoking set, which is simple in structure and has strong practicality.

[0106] Embodiment three:

[0107] The only difference between this embodiment and embodiment two is that:

[0108] The detection mechanism is located outside the air inlet cavity.

[0109] In addition, the rest of the structure is the same as that of embodiment two.

[0110] By arranging the detection mechanism outside the air inlet cavity, the problem that the existence of the detection mechanism itself affects the air inlet of the air inlet cavity caused by arranging the detection mechanism in the air inlet cavity can be avoided, and the practicality is strong.

[0111] Embodiment four:

[0112] The only difference between this embodiment and embodiment three is that:

[0113] The detection mechanism is a first range finder, and the first range finder is installed on the body near the suction end;

[0114] The first range finder is used to detect the distance between the body and the obstacle, and when the distance is less than a first set value, the first range finder sends a preset signal to the controller, and the controller counts once.

[0115] In addition, the rest of the structure is the same as that of Example Three.

[0116] The distance between the smoking tool and the obstacle (such as the user's face) is detected by the first range finder, and the determination of the puffing action is completed, which is simple in structure, convenient to install, and has strong practicability.

[0117] In this embodiment, the first set value can be 1 cm, and specifically, the specific value of the first set value can be set according to the actual situation of the smoking tool, and can be set to 1.5 cm, 2 cm, etc.

[0118] In the use process, based on the characteristics that the distance between the smoking tool and the user's face is small when the user puffs, and the distance between the smoking tool and the user's face is large during the interval of puffing;

[0119] The first range finder is used as a detection mechanism to detect the distance between the user's face and the smoking tool, and when the value detected by the first range finder is less than the first set value, i.e., the distance between the position of the smoking tool and the user's face is less than 1 cm, it is determined that the user puffs once, and then the controller counts once. According to the number of puffing actions detected by the detection mechanism, the power source control adjusting piece moves in the installation cavity, so that the adjusting piece moves to different positions in the installation cavity, so that the air inlet cavity has different air inlet resistance, so as to change the air flow of the smoking material part, and then in the way of different air flow for each puff cooperating with different release amount of smoking material for each puff, the release amount of the smoking material entering the user's oral cavity remains relatively stable, and the user experience is improved.

[0120] Example Five:

[0121] Compared with Example Four, the only different structure is:

[0122] The detection mechanism is a gyroscope, and the gyroscope is installed on the body;

[0123] When the gyroscope detects that the body changes from a horizontal state to a vertical state, the gyroscope sends a preset signal to the controller, and the controller counts once;

[0124] The horizontal state is a state in which the included 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 included angle between the central axis of the body and the horizontal plane is greater than β; α = β = 45°.

[0125] The rest of the structure is the same as example four.

[0126] In this embodiment, in use, based on the user inhaling, the smoking set is lifted for inhaling, so that the smoking set is generally in a horizontal state, and in the interval of inhaling, the smoking set is put down, so that the smoking set is generally in a vertical state;

[0127] The gyroscope is used as a detection mechanism to measure the included angle between the smoking set and the horizontal plane, when the included angle between the smoking set and the horizontal plane is less than 45°, it is determined that the smoking set is in a horizontal state, that is, in an inhaling state;

[0128] When the included angle between the smoking set and the horizontal plane is greater than 45°, it is determined that the smoking set is in a vertical state, that is, in an interval of inhaling;

[0129] Through the case of conversion from the horizontal state to the vertical state in the two determinations, it is determined that the user inhales once, and then the controller counts once.

[0130] Example six:

[0131] Compared with example five, the only different structure is that α=20° and β=70°.

[0132] The rest of the structure is the same as example five.

[0133] By setting α and β as two different values, and reserving a blank interval between α and β, the problem of controller error counting caused by the smoking set being jolted by external force or improper user operation can be reduced, and the practicability is stronger.

[0134] Example seven:

[0135] Compared with example five, the only different structure is that:

[0136] The detection mechanism is a gyroscope, and the gyroscope is installed on the body;

[0137] When the gyroscope detects that the body is converted from the vertical state to the horizontal state, the gyroscope sends a preset signal to the controller, and the controller counts once;

[0138] The horizontal state is a state in which the included 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 included angle between the central axis of the body and the horizontal plane is greater than β; α=β=45°.

[0139] The rest of the structure is the same as example five.

[0140] In the embodiment, in use, based on the user lifting the smoking set for smoking when puffing, the smoking set is generally in a horizontal state, and in the interval of smoking, the smoking set is generally in a vertical state;

[0141] The gyroscope is used as a detection mechanism to measure the angle between the smoking set and the horizontal plane. When the angle between the smoking set and the horizontal plane is less than 45°, it is determined that the smoking set is in a horizontal state, that is, in a smoking state.

[0142] When the angle between the smoking set and the horizontal plane is greater than 45°, it is determined that the smoking set is in a vertical state, that is, in the interval of smoking.

[0143] In the two determinations, when the vertical state is converted to the horizontal state, it is determined that the user puffs once, and the controller counts once.

[0144] Embodiment Eight:

[0145] The only difference between the embodiment and Embodiment Seven is that α=20° and β=70°.

[0146] Except for this, the rest of the structure is the same as Embodiment Seven.

[0147] 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 the smoking set being jolted by external force or the user operating improperly can be reduced, and the practicability is stronger.

[0148] Embodiment Nine:

[0149] The only difference between the embodiment and Embodiment Four is that:

[0150] The detection mechanism is a button installed on the body.

[0151] After the user puffs once, the button is pressed once, the button sends a preset signal to the controller, and the controller counts once.

[0152] Except for this, the rest of the structure is the same as Embodiment Four.

[0153] By pressing the button, the puffing action is directly counted manually, the structure is simple, the manufacturing cost is low, and the practicability is stronger.

[0154] In the embodiment, in use, based on the user pressing the button once for each puff, it is determined that the user puffs once, and the controller counts once.

[0155] Embodiment Ten:

[0156] The only difference between the embodiment and Embodiment Four is that:

[0157] The body is provided with a connecting portion in contact with the user's lips, and the detection mechanism is installed on the connecting portion.

[0158] The detection mechanism is a second range finder, and the second range finder is installed on the periphery of the connecting portion.

[0159] The second range finder is used to detect the distance between the connecting portion and the obstacle, and when the distance is less than a second set value, the second range finder sends a preset signal to the controller, and the controller counts once.

[0160] In addition, the remaining structure is the same as that of Example Four.

[0161] In this embodiment, the second set value can be 0. Specifically, the specific value of the second set value can be set according to the actual situation of the smoking set itself, and can be set to 0.1 cm, 0.2 cm, etc.

[0162] In use, based on the contact between the user's lips and the connecting portion when the user is smoking, and the large distance between the smoking set and the user's lips during the interval between puffs;

[0163] The second range finder is used as a detection mechanism to detect the distance between the user's lips and the smoking set, and when the value detected by the second range finder is less than the second set value, i.e., the distance between the position of the smoking set and the user's lips is 0, it is determined that the user has smoked once, and the controller counts once.

[0164] Example Eleven:

[0165] Compared with Example Ten, the only different structure is:

[0166] The second range finder is N, and is uniformly arranged on the periphery of the connecting portion, N≥2; preferably N is 2;

[0167] When all the second range finders simultaneously send a preset signal to the controller, the controller counts once.

[0168] In addition, the remaining structure is the same as that of Example Ten.

[0169] In fact, only one second range finder can also be set according to the actual situation, and in this embodiment, at least two second range finders are arranged, and the controller is limited to counting only when all the second range finders simultaneously send a preset signal, i.e., when multiple second range finders simultaneously detect that the distance to the lips is 0, which can avoid the problem of false counting caused by the connecting portion accidentally touching a flat object such as an arm during use, and has strong practicality.

[0170] Example Twelve:

[0171] Compared with Example Eleven, the only different structure is:

[0172] The detection mechanisms are N in number and are uniformly arranged on the circumferential side of the connecting portion, N≥3; preferably N is 3;

[0173] When N is an even number, the controller counts once when at least N / 2+1 detection mechanisms simultaneously send the preset signal to the controller;

[0174] When N is an odd number, the controller counts once when at least (N-1) / 2+1 detection mechanisms simultaneously send the preset signal to the controller.

[0175] In addition, the rest of the structure is the same as that of Example Eleven.

[0176] In fact, according to actual conditions, on the basis of setting multiple second range finders, the controller can count once when other numbers of second range finders are triggered. In this embodiment, at least two detection mechanisms are arranged, and the controller is limited to counting only when more than half, but not all, detection mechanisms simultaneously send the preset signal.

[0206] In addition, the rest of the structure is the same as that of embodiment fifteen.

When the smoking tool for heating the heat-not-burn cigarette with a filter is used, the user's lips do not directly contact the body of the smoking tool, but directly contact the filter of the heat-not-burn cigarette.

[0230] The light receiver is used as a detection mechanism to detect the contact between the user's lips and the smoking set. When the light receiver is touched by the user's lips, the light received by the light receiver becomes weaker. Based on this indicator, it is determined that the user has taken a puff, and the controller counts one.

[0231] Embodiment twenty-two:

In the embodiment, at least two detection mechanisms are set, and the controller only counts when more than half of the detection mechanisms send the preset signal at the same time, instead of all the detection mechanisms. Thus, the problem of false counting caused by the connection part being accidentally touched by a flat object such as an arm during use can be avoided, and the problem of being unable to count caused by not all positions of the connection part being in contact with the user's lips during the closing of the lips can be avoided.
