[0022] Figure 1 It is a schematic structural diagram of a cigarette smoke suction and capture device provided by an embodiment of the present invention. This embodiment is applicable to simulating the inhalation and exhalation processes of cigarettes. As Figure 1 shown, the cigarette smoke suction and capture device 10 provided in this embodiment includes: a suction part simulation module 101, a signal control module 102, and a power control module 103. The structural composition of the cigarette smoke suction and capture device 10 provided in this embodiment will be specifically described below.

[0023] Among them, the signal control module 102 is used to receive control instructions and exhalation control signals corresponding to the cigarette smoking task, and determine multiple second-part simulation modules associated with the cigarette smoking task based on the control instructions; wherein the second-part simulation module is a module in the first-part simulation module; the power control module 103 is used to receive the exhalation control signal sent by the signal control module, so as to adjust the pressure information of the environment in which the preset components in the smoking part simulation module 101 are located based on the exhalation control signal, and feed the pressure information back to the signal control module 102; the signal control module 102 is also used to adjust the working states of multiple second-part simulation modules based on the pressure information, so as to simulate the inhalation and exhalation of the cigarette sample based on the pressure information and the adjusted second-part simulation module, so that the inhaled cigarette smoke flows in the second-part simulation module and is exhaled; the smoking part simulation module 101 is used to capture smoke substances in the cigarette smoke during the flow of the cigarette smoke.

[0024] Among them, the suction part simulation module 101 can be an overall structure composed of first part simulation modules corresponding to multiple parts associated with the cigarette smoking process. The overall structure can simulate the subject's inhalation and exhalation process under the action of an external power device. Exemplarily, the multiple parts associated with the cigarette smoking process may include the oral cavity, nasal cavity, throat and trachea. It should be noted that when the subject inhales a cigarette, the inhaled cigarette smoke may or may not pass through the lungs. Therefore, in this embodiment, the multiple parts associated with the cigarette smoking process may also include the lungs. The first part simulation module can be a three-dimensional model constructed based on the part, that is, a three-dimensional simulation model of the part. Exemplarily, if the part is the nasal cavity, the first part simulation module corresponding to the nasal cavity can be a nasal cavity simulation module.

[0025] Optionally, when the multiple first-part simulation modules include a lung simulation module, the lung simulation module is constructed with a flexible material, and the other first-part simulation modules except the lung simulation module in the multiple first-part simulation modules are constructed with a rigid material.

[0026] Flexible materials are materials that are flexible, bendable, and deformable, such as silicone and rubber. They can deform significantly without breaking when subjected to force. Rigid materials are hard, non-deformable materials, such as plastic and metal. They have good strength and stability and can maintain a fixed shape.

[0027] It should be noted that the advantage of constructing the lung simulation module with flexible materials is that it can better simulate the physiological characteristics of the lung, such as respiratory movement and elastic deformation, making the simulation effect more realistic, and enabling the lung simulation module to quickly return to its original state after being subjected to external forces. The advantage of constructing other first part simulation modules with rigid materials is that it can provide a stable support structure for the entire suction part simulation module, making it not easily deformed or damaged during use, facilitating maintaining the overall shape and function of the module, ensuring the accuracy and consistency of the simulation effect, and being able to self-support to maintain the structure and morphology of its own respiratory tract.

[0028] In this embodiment, first part simulation modules corresponding to multiple parts associated with the cigarette suction process can be constructed. Further, multiple first part simulation modules can be assembled, and the overall structure obtained after assembly can be used as the suction part simulation module. Optionally, each first part simulation module is respectively constructed based on the scan data corresponding to the corresponding part; multiple first part simulation modules are assembled according to the connection sequence of the parts of the real respiratory system to obtain the suction part simulation module 101.

[0029] Among them, the scan data can be relevant data information obtained after scanning the part by a scanning device. Exemplarily, the scan data can include, but is not limited to, CT images. It should be noted that the scan data can be obtained in real time from a medical imaging device, or retrieved from an image database, or received as a scan data transmission from an external device. This embodiment does not make specific limitations in this regard. It can be understood that the connection sequence of the parts of the real respiratory system is successively the nasal cavity, oropharynx, larynx, trachea, bronchi, and lungs.

[0030] In specific implementation, multiple parts corresponding to the cigarette suction process can be determined. For multiple parts, scan data corresponding to the parts can be obtained, and the scan data can be processed based on a forming technique to obtain a first part simulation module corresponding to the part. Further, multiple first part simulation modules can be assembled according to the connection sequence of the parts of the real respiratory system, and the overall structure obtained after assembly can be used as the suction part simulation module 101. Among them, the forming technique can include processes such as injection molding, casting, 3D printing, or lathe cutting. Multiple first part simulation modules can be assembled into a whole in various ways. Optionally, multiple first part simulation modules can be of a quick-insert structure, that is, assembled into a whole by means such as threads and buckles. The advantage of such a setting is that it is convenient for quick disassembly and assembly, and it is also convenient for cleaning the first part simulation modules.

[0031] Among them, the signal control module 102 can be a device capable of receiving control instructions and generating and outputting control signals based on the control instructions. The signal control module 102 can be any device capable of receiving instructions and outputting control signals based on the control instructions. Optionally, the signal control module 102 can be a PLC electronic control unit.

[0032] Among them, the cigarette smoking task can be a test task that simulates the smoking processes of different types of cigarettes. Optionally, the cigarette smoking task includes an overall cyclic smoking task and / or a partial cyclic smoking task. The overall cyclic smoking task means that when smoking, the smoke is inhaled through the mouth, swallowed by the throat, passes through the lungs, and is exhaled from the nose and / or mouth, including cyclic smoking with mouth inhalation and nose exhalation, cyclic smoking with mouth inhalation and mouth exhalation, and cyclic smoking with mouth inhalation and simultaneous exhalation from the nose and mouth, etc. The partial cyclic smoking task means that when smoking, it is inhaled through the mouth and not swallowed, and is directly exhaled from the nose and / or mouth. In this embodiment, for different cigarette smoking tasks, different control instructions can be corresponding, and the second part simulation modules associated with the cigarette smoking task are also different. The second part simulation module is the module in the first part simulation module that is associated with the cigarette smoking task. Exemplarily, assuming that the cigarette smoking task is the cyclic smoking with mouth inhalation and nose exhalation in the overall cyclic smoking task, the multiple second part simulation modules associated with the cigarette smoking task can include an oral cavity simulation module, a nasal cavity simulation module, a throat simulation module, a trachea simulation module, and a lung simulation module. The working state can be used to characterize whether smoke flows through its corresponding second part simulation module. Optionally, the working state includes a running state or a paused state. When the second part simulation module is in the running state, it can characterize that cigarette smoke will flow through the second part simulation module; when the second part simulation module is in the paused state, it can characterize that cigarette smoke will not flow through the second part simulation module. It should be noted that when simulating the inhalation and exhalation of a cigarette sample, during inhalation, among the multiple second part simulation modules associated with the cigarette smoking task, there will be modules with a closed working state and modules with an open working state; during exhalation, among the multiple second part simulation modules associated with the cigarette smoking task, there will be modules with a closed working state and modules with an open working state. Exemplarily, assuming that the cigarette smoking task is the cyclic smoking with mouth inhalation and nose exhalation in the overall cyclic smoking task, during the inhalation of the cigarette sample, the nasal cavity simulation module is in the paused state, and the oral cavity simulation module, the throat simulation module, the trachea simulation module, and the lung simulation module are in the running state; during the exhalation of the cigarette sample, the oral cavity simulation module is in the paused state, and the nasal cavity simulation module, the throat simulation module, the trachea simulation module, and the lung simulation module are in the running state.

[0033] In this embodiment, for controlling whether the cigarette smoke flows through the first part simulation module, that is, for controlling the working state of the first part simulation module, it can be achieved in various ways. Optionally, an electromagnetic valve is provided on each first part simulation module; the electromagnetic valve is used to control the working state of the associated first part simulation module by adjusting the valve state. It should be noted that, in addition to controlling the working state of the first part simulation module by adjusting the valve state of the electromagnetic valve, it can also include achieving it by controlling the valve state of a mechanical valve or a pneumatic valve or by a flow controller, etc.

[0034] In a specific implementation, when determining a cigarette suction task, the signal control module 102 can receive a control instruction and a puff control signal corresponding to the cigarette suction task. Further, a plurality of second part simulation modules associated with the cigarette suction task can be determined based on the control instruction, and the puff control signal can be sent to the power control module 103 so that the power control module 103 can adjust the pressure information based on the puff control signal. Among them, the puff control signal can be used to control whether the power control module 103 provides suction power or exhalation power. The puff control signal can include a suction control signal and / or an exhalation control signal.

[0035] Among them, the power control module 103 can be used to provide suction power for the suction part simulation module 101 so that the suction part simulation module 101 can simulate the inhalation and exhalation processes of the object. The power control module 103 can make the suction part simulation module 101 simulate the inhalation and exhalation processes of the object by adjusting the pressure information. In this embodiment, a cigarette sample in a burning state is provided in the preset part simulation module in the suction part simulation module 101. Furthermore, the suction part simulation module 101 can simulate the inhalation and exhalation of the cigarette sample.

[0036] In a specific implementation, when the power control module 103 receives the puff control signal, it can adjust the pressure information of the environment where the preset components in the suction part simulation module are located based on the puff control signal, and feedback the pressure information to the signal control module 102 so that the signal control module 102 can adjust the working state of a plurality of second part simulation modules based on the pressure information. Furthermore, based on the pressure information and the adjusted second part simulation modules, the inhalation and exhalation of the cigarette sample can be simulated.

[0037] In this embodiment, the signal control module is connected to the suction part simulation module by a wired transmission method or a wireless transmission method; the signal control module is connected to the power control module by a wired transmission method or a wireless transmission method.

[0038] In this embodiment, when the aspiration site simulation module includes a lung simulation module, the preset component may include the lung simulation module. When the aspiration site simulation module does not include a lung simulation module, the preset component may include a solenoid valve for controlling the trachea simulation module.

[0039] Simulating the inhalation and exhalation of a cigarette sample includes a cigarette inhalation process and a cigarette exhalation process. The execution processes of these two processes will be described below.

[0040] Optionally, the inhalation / exhalation control signal includes an aspiration control signal; the pressure information includes first pressure information; the power control module 103 is configured to receive the aspiration control signal sent by the signal control module 102, adjust the pressure information of the environment where the preset component in the aspiration site simulation module 101 is located to the first pressure information based on the aspiration control signal, and feedback the first pressure information to the signal control module 102; the signal control module 102 is configured to generate a first valve control signal corresponding to each second site simulation module based on the first pressure information, and send the first valve control signal to the solenoid valve on the corresponding second site simulation module respectively, so as to adjust the valve state of the solenoid valve based on the first valve control signal, determine the working state of the second site simulation module based on the valve state, and simulate the inhalation of the cigarette sample based on the first pressure information and the adjusted second site simulation module, so that the inhaled cigarette smoke flows in the second site simulation module.

[0041] Among them, the aspiration control signal may be a trigger signal for controlling the power control module to provide aspiration power. The first pressure information may be the pressure information obtained by decompressing the initial pressure information. The initial pressure information is the pressure information corresponding to the balance of the internal and external pressures of the environment where the preset component is located. The first valve control signal may be a valve control signal associated with the cigarette aspiration process, and this valve control signal is used to control whether the corresponding solenoid valve is in the valve open state or the valve closed state. Different second site simulation modules correspond to different first valve control signals. The first valve control signal corresponding to the second site simulation module can be used to control whether the solenoid valve provided on the second site simulation module is in the valve open state or the valve closed state. When the solenoid valve is in the valve open state, the working state of the second site simulation module is the running state, and when the solenoid valve is in the valve closed state, the working state of the second site simulation module is the pause state.

[0042] In this embodiment, in order to provide cigarette suction power and cigarette exhalation power, the power control module 103 can be a device constructed by simulating the thoracic cavity structure. Optionally, the power control module 103 includes a sealed cavity 1031, a piston 1032, and a motor unit 1033. Among them, the preset components in the suction part simulation module 101 are located inside the sealed cavity 1031; the outer diameter of the piston 1032 is closely fitted with the inner diameter of the sealed cavity 1031; the motor unit 1033 is configured to drive the piston 1032 to move in a first direction when receiving a suction control signal, so as to increase the volume inside the sealed cavity 1031 and adjust the pressure information of the environment where the preset components are located to the first pressure information.

[0043] Among them, the sealed cavity 1031 is a closed space structure, which can usually be made of materials with a certain strength and sealing performance, such as metal or high-strength plastic, etc. In this embodiment, the sealed cavity 1031 can be used to accommodate the piston 1032 and the preset components, and change the size of its internal space by the movement of the piston 1032, thereby adjusting the internal pressure. At the same time, the sealed cavity 1031 can also be used to prevent external gases or other substances from entering, ensuring the stability and independence of the internal environment. The piston 1032 can be a cylindrical component, and its outer diameter is closely fitted with the inner diameter of the sealed cavity 1031, and it can reciprocate axially inside the sealed cavity 1031. The function of the piston 1032 is to change the internal volume of the sealed cavity 1031 through its movement, so as to realize the adjustment of the internal pressure of the sealed cavity 1031. The motor unit 1033 is a power-providing device, mainly composed of a motor and related control circuits and transmission devices. The first direction can be the direction that makes the volume inside the sealed cavity 1031 increase. Exemplarily, assuming that the sealed cavity 1031 is a cylindrical space, and the piston 1032 moves from top to bottom to increase the volume inside the sealed cavity 1031, then the first direction can be from top to bottom at this time.

[0044] In a specific implementation, when the power control module 103 receives the suction control signal sent by the signal control module 102, it indicates that the pressure in the sealing cavity 1031 of the power control module 103 needs to be adjusted to simulate the suction process. At this time, the motor unit 1033 starts to work based on the suction control signal, driving the piston 1032 to move along the first direction. Since the outer diameter of the piston 1032 fits tightly with the inner diameter of the sealing cavity 1031, the movement of the piston 1032 will change the internal volume of the sealing cavity 1031. Further, as the piston 1032 moves along the first direction, the internal volume of the sealing cavity 1031 gradually increases. Furthermore, when the internal volume of the sealing cavity 1031 gradually increases, the pressure inside it will gradually decrease. Further, by precisely controlling the moving distance and speed of the piston 1032 through the motor unit 1033, the pressure in the sealing cavity 1031, that is, the pressure information of the environment where the preset component is located, can be adjusted to the first pressure information, and the first pressure information is fed back to the signal control module 102.

[0045] Further, when the signal control module 102 receives the first pressure information, it can generate the first valve control signal corresponding to each second part simulation module based on the first pressure information, and send the first valve control signal to the solenoid valve on the corresponding second part simulation module respectively. Furthermore, for multiple second part simulation modules, the valve state of the solenoid valve on the second part simulation module can be adjusted based on the first valve control signal corresponding to the second part simulation module. Furthermore, the working state of the second part simulation module can be determined based on the valve state of the solenoid valve, so as to simulate the inhalation of the cigarette sample according to the first pressure information and the adjusted second part simulation module, and make the cigarette smoke sucked flow in the second part simulation module.

[0046] Optionally, the suction and exhalation control signal includes an exhalation control signal; the pressure information includes the second pressure information; the power control module 103 is configured to receive the exhalation control signal sent by the signal control module 102, adjust the pressure information of the environment where the preset component in the suction part simulation module is located to the second pressure information based on the exhalation control signal, and feed back the second pressure information to the signal control module 102; the signal control module 102 is configured to generate the second valve control signal corresponding to each second part simulation module based on the second pressure information, and send the second valve control signal to the solenoid valve on the corresponding second part simulation module respectively, so as to adjust the valve state of the solenoid valve based on the second valve control signal, determine the working state of the second part simulation module based on the valve state, and simulate the exhalation of the cigarette sample according to the second pressure information and the adjusted second part simulation module, so that the cigarette smoke flowing in the second part simulation module is discharged to the outside of the device.

[0047] Among them, the exhalation control signal can be a trigger signal for controlling the power control module to provide exhalation power. The second pressure information can be the pressure information obtained by boosting on the basis of the current pressure information. The second valve control signal can be a valve control signal associated with the cigarette exhalation process, and this valve control signal is used to control whether the corresponding solenoid valve is in the valve open state or the valve closed state. Different second part simulation modules correspond to different second valve control signals.

[0048] In this embodiment, the motor unit 1033 is further configured to, when receiving the exhalation control signal, drive the piston 1032 to move along the second direction, so as to reduce the volume inside the sealing cavity 1031 and adjust the pressure information of the environment where the preset component is located to the second pressure information.

[0049] Among them, the second direction can be the direction in which the volume inside the sealing cavity 1031 decreases. The second direction can also be the direction opposite to the first direction. Exemplarily, continuing with the above example, assuming that the first direction is from top to bottom, then the second direction can be from bottom to top.

[0050] In specific implementation, when the power control module 103 receives the exhalation control signal sent by the signal control module 102, it can indicate that it is necessary to adjust the pressure in the sealing cavity 1031 of the power control module 103 to simulate the exhalation process. At this time, the motor unit 1033 starts to work based on the suction control signal, driving the piston 1032 to move along the second direction. As the piston 1032 moves along the second direction in the sealing cavity 1031, the volume inside the sealing cavity 1031 gradually decreases. Furthermore, when the volume inside the sealing cavity 1031 gradually decreases, the pressure inside it will gradually increase. Further, by precisely controlling the moving distance and speed of the piston 1032 by the motor unit 1033, the pressure in the sealing cavity 1031, that is, the pressure information of the environment where the preset component is located, can be adjusted to the second pressure information, and the second pressure information is fed back to the signal control module 102.

[0051] Furthermore, when the signal control module 102 receives the second pressure information, it can generate second valve control signals corresponding to each second part simulation module based on the second pressure information, and send the second valve control signals to the solenoid valves on the corresponding second part simulation modules respectively. Then, for multiple second part simulation modules, the valve states of the solenoid valves on the second part simulation modules can be adjusted based on the second valve control signals corresponding to the second part simulation modules. Furthermore, the working states of the second part simulation modules can be determined based on the valve states of the solenoid valves, so as to simulate the exhalation of the cigarette sample according to the second pressure information and the adjusted second part simulation modules, and make the cigarette smoke flowing in the second part simulation module discharged to the outside of the device.

[0052] In this embodiment, during the flow of cigarette smoke in the second part simulation module, the smoke substances of the cigarette smoke can also be captured by the suction part simulation module 101. Optionally, a smoke collection substrate is provided on each first part simulation module; wherein, the smoke collection substrate is used to capture the smoke substances in the cigarette smoke when the cigarette smoke flows through the second part simulation module.

[0053] Among them, the smoke collection substrate can be a plate-shaped component with specific structures and functions, and a variety of elements for smoke collection and treatment can be integrated on this component. For example, it may include adsorption materials for adsorbing or capturing chemical components in the smoke. In this embodiment, since the main substances in the oral cavity, nasal cavity, throat, trachea, and lungs are different, the smoke collection substrates provided on the first part simulation modules are also different. Furthermore, different electrostatic modification techniques can be used on the surface of the smoke collection substrate according to the chemical components of its main substances to change its surface chemical composition and microstructure. Thus, the smoke collection substrates provided on the first part simulation modules can be used to simulate the capture of the main substances in the oral cavity, nasal cavity, throat, trachea, and lungs. Exemplarily, for the oral cavity simulation module, the smoke substances captured by the provided smoke collection substrate include moisture, nicotine, and volatile aldehydes; for the nasal cavity simulation module, the smoke substances captured by the provided smoke collection substrate include nicotine, volatile aroma substances, and fine particles; for the throat simulation module, the smoke substances captured by the provided smoke collection substrate include nicotine, irritating substances, and tar; for the trachea simulation module, the smoke substances captured by the provided smoke collection substrate include tar, nicotine, and harmful gases; for the lung simulation module, the smoke substances captured by the provided smoke collection substrate include nicotine, tar, carbon monoxide, and free radicals.

[0054] In specific implementation, a smoke collection substrate is provided on each first part simulation module. Then, during the flow of the sucked cigarette smoke in the second part simulation module, the smoke substances in the cigarette smoke can be collected based on the smoke collection substrate provided on the second part simulation module. The advantage of such a setting is that by adjusting the chemical composition of the smoke collection substrate, the smoke components on the oral cavity, nasal cavity, throat, and lungs can be selectively captured more specifically. Thus, it can provide theoretical support for the sensory evaluation of cigarettes.

[0055] In this embodiment, the cigarette smoke extraction and capture device 10 further includes a robotic arm 104; wherein, the signal control module 102 is further configured to send a robotic arm control signal to the robotic arm 104, so that the robotic arm 104 sets and / or removes a cigarette sample on the preset part simulation module of the suction part simulation module 101 based on the robotic arm control signal.

[0056] Among them, the preset part simulation module is the module that sets the cigarette sample among multiple first part simulation modules. Optionally, the preset part simulation module can be an oral cavity simulation module. The robotic arm 104 can be a movable component, usually composed of a motor, a transmission mechanism, a robotic arm, etc., and can perform precise actions under signal control to complete operations such as grasping and moving. The robotic arm control signal is an electrical signal sent by the signal control module 102 to the robotic arm 104. This electrical signal contains specific instructions regarding the actions of the robotic arm, such as the direction of movement, speed, timing of grasping and releasing, etc., to precisely control the movement and operation of the robotic arm 104.

[0057] In a specific implementation, before the cigarette smoke suction and capture device 10 executes the cigarette suction task, the signal control module 102 can send a robotic arm control signal to the robotic arm 104. Further, when the robotic arm 104 receives the robotic arm control signal, a cigarette sample can be set on the preset part simulation module of the suction part simulation module 101 based on the robotic arm control signal. Furthermore, the inhalation and exhalation of the cigarette sample can be simulated based on the cigarette smoke suction and capture device 10. Further, after the execution of the cigarette suction task is completed, the signal control module 102 can send a robotic arm control signal to the robotic arm 104. Further, when the robotic arm 104 receives the robotic arm control signal, the cigarette sample can be taken out from the preset part simulation module based on the robotic arm control signal.

[0058] Exemplarily, a specific example is used to illustrate the overall working process of the cigarette smoke suction and capture device 10. Assume that the cigarette suction task is the oral inhalation and nasal exhalation cyclic suction task in the overall cyclic suction task. As Figure 1As shown, the signal control module 102 can receive the control instruction and the suction control signal corresponding to the cigarette suction task, send the suction control signal to the power control module, and determine, based on the control instruction, a plurality of second part simulation modules associated with the cigarette suction task from a plurality of first part simulation modules in the suction part simulation module 101, including the oral cavity simulation module 3, the nasal cavity simulation module 2, the pharynx simulation module 4, the trachea simulation module 5, and the lung simulation module 6. Among them, a solenoid valve 3-1 is provided on the oral cavity simulation module 3; a solenoid valve 2-1 is provided on the nasal cavity simulation module 2; a solenoid valve 4-1 is provided on the pharynx simulation module 4; a solenoid valve 5-1 is provided on the trachea simulation module 5. Further, in the case where the power control module 103 receives the suction control signal, the motor unit 1033 can be controlled to drive the piston 1032 to move downward in the sealed cavity 1031. The volume inside the sealed cavity 1031 gradually increases, and the pressure inside it gradually decreases, adjusting the pressure information of the environment where the lung simulation module 6 is located to the first pressure information and feeding back the first pressure information to the signal control module 102. Further, in the case where the signal control module 102 receives the first pressure information, a first valve control signal corresponding to the oral cavity simulation module 3, a first valve control signal corresponding to the nasal cavity simulation module 2, a first valve control signal corresponding to the pharynx simulation module 4, and a first valve control signal corresponding to the trachea simulation module 5 can be generated based on the first pressure information. Further, the first valve control signal corresponding to the oral cavity simulation module 3 is sent to the solenoid valve 3-1 to control the solenoid valve 3-1 to open; the first valve control signal corresponding to the nasal cavity simulation module 2 is sent to the solenoid valve 2-1 to control the solenoid valve 2-1 to close; the first valve control signal corresponding to the pharynx simulation module 4 is sent to the solenoid valve 4-1 to control the solenoid valve 4-1 to open; the first valve control signal corresponding to the trachea simulation module 5 is sent to the solenoid valve 5-1 to control the solenoid valve 5-1 to open. Further, in order to maintain the pressure balance inside and outside the sealed cavity 1031, the cigarette sample provided on the oral cavity simulation module 3 is sucked. The sucked cigarette smoke enters the oral cavity simulation module 3 through the solenoid valve 3-1, and then enters the lung simulation module 6 after passing through the pharynx simulation module 4 and the trachea simulation module 5, diffuses and is stored in the lung simulation module 6, and at this time, the lung lobe simulation module 6 expands.

[0059] Further, after a preset duration, an exhalation control signal can be sent to the power control module 103 based on the signal control module 102. When the exhalation control signal is received through the power control module 103, the motor unit 1033 can be controlled to drive the piston 1032 to move upward in the sealed chamber 1031. The volume inside the sealed chamber 1031 gradually decreases, and the pressure inside it gradually increases, adjusting the pressure information of the environment where the lung simulation module 6 is located to the second pressure information, and feeding back the second pressure information to the signal control module 102. Further, when the signal control module 102 receives the second pressure information, a second valve control signal corresponding to the oral cavity simulation module 3, a second valve control signal corresponding to the nasal cavity simulation module 2, a second valve control signal corresponding to the pharynx simulation module 4, and a second valve control signal corresponding to the trachea simulation module 5 can be generated based on the second pressure information. Further, the second valve control signal corresponding to the oral cavity simulation module 3 is sent to the solenoid valve 3-1 to control the solenoid valve 3-1 to close; the second valve control signal corresponding to the nasal cavity simulation module 2 is sent to the solenoid valve 2-1 to control the solenoid valve 2-1 to open; the second valve control signal corresponding to the pharynx simulation module 4 is sent to the solenoid valve 4-1 to control the solenoid valve 4-1 to open; the second valve control signal corresponding to the trachea simulation module 5 is sent to the solenoid valve 5-1 to control the solenoid valve 5-1 to open. Further, according to the second pressure information, the cigarette smoke can be discharged from the lung lobe simulation module 6 through the trachea simulation module 5, the pharynx simulation module 4, and the nasal cavity simulation module 2 to the outside of the device, that is, the overall cyclic suction task of the cigarette smoke from the mouth and out through the nose is completed.
