[0026] Embodiment 1

[0027] Figure 1The figure is a schematic structural diagram of a flue gas detection device based on lung respiration provided by an embodiment of the present invention. This embodiment is applicable to the scenario of detecting the properties of flue gas particles deposited in the lungs during the lung respiration process of cigarette flue gas. Refer to Figure 1 , the flue gas detection device based on lung respiration provided in this embodiment includes: an oral simulation module 110, a respiratory tract simulation module 120 connected to the oral simulation module 110, a double-layer lung module 130 connected to the respiratory tract simulation module 120, a heat preservation device 140, a humidification device 150, a motor 160, a control module 170, and a detection module 180. The structural composition of the flue gas detection device based on lung respiration in this embodiment will be specifically described below.

[0028] The double-layer lung module 130 includes a lung simulation module and a thoracic cavity simulation module; the lung simulation module is located inside the cavity of the thoracic cavity simulation module; the heat preservation device 140 is arranged on the inner wall of the thoracic cavity simulation module; the humidification device 150 is connected to the lung simulation module; the motor 160 is connected to the thoracic cavity simulation module; the heat preservation device 140 is a heating strip.

[0029] The control module 170 is configured to, when receiving a lung respiration detection request, control the working state of the heat preservation device 140 to be in a heating state, control the working state of the humidification device 150 to be in a humidifying state, and control the working state of the motor 160 to be in a pressurizing state, so as to increase the pressure in the cavity between the thoracic cavity simulation module and the lung simulation module, and to adjust the temperature and humidity of the breathing environment in the lung simulation module;

[0030] The control module 170 is configured to obtain the humidity of the breathing environment in the lung simulation module, the temperature of the breathing environment in the lung simulation module, and the pressure in the cavity between the thoracic cavity simulation module and the lung simulation module, and when the temperature, humidity, and pressure reach preset detection conditions, control the working state of the oral simulation module 110 to be adjusted from a closed state to an open state, so that the flue gas generated after lighting a cigarette enters the lung simulation module through the oral simulation module 110;

[0031] The detection module 180 is configured to obtain the flue gas particles on the inner wall of the lung simulation module and detect the flue gas particles to obtain a detection result.

[0032] Among them, the lung respiration detection request can be an instruction or program for indicating a simulated lung respiration test of smoke. The inner wall of the chest cavity simulation module is pasted with a heat-insulating material, and a heating strip is wound around the surface of the heat-insulating material, so that the heating strip can provide a constant-temperature environment for the smoke inhalation test, making the lungs have an approximate temperature to that of the human body. The humidifying device 150 is connected to the inner cavity of the lung simulation module, so that the moisture generated by the humidifying device 150 can enter the inner cavity of the lung simulation module, providing a constant-humidity environment for the smoke inhalation test and making the lungs have an approximate humidity to that of the human body. The smoke particles can be soot particles such as tar and nicotine deposited in the lungs due to cigarette smoking. The preset detection conditions can refer to the conditions for judging whether the lung environment for cigarette smoke testing has been reached. For example, the preset detection conditions can be that the temperature reaches the temperature of the lungs when a human smokes a cigarette, the humidity reaches the humidity of the lungs when a human smokes a cigarette, the pressure reaches the pressure of the lungs when a human smokes a cigarette, etc.

[0033] In this embodiment, the flue gas detection device may further include a display screen. In this way, when it is detected that the flue gas detection control on the display screen is triggered, a lung respiration detection request may be generated and sent to the control module 170; alternatively, when the control module 170 receives a program or code for instructing flue gas detection, it is considered that a lung respiration detection request has been received; or, when a timing task for triggering flue gas detection is triggered, it is considered that a lung respiration detection request has been received. At this time, the control module 170 may control the working state of the heat preservation device 140 to be adjusted from the closed state or the idle state to the heating state. By heating, the temperature in the cavity between the chest cavity simulation module and the lung simulation module is increased to simulate the temperature environment during normal human breathing. Control the working state of the humidifying device 150 to be adjusted from the closed state or the idle state to the humidifying state to increase the humidity in the cavity of the lung simulation module and simulate the moist air inhaled during human breathing. Control the working state of the motor 160 to be in the pressurized state so that the motor 160 extracts the air in the cavity between the chest cavity simulation module and the lung simulation module, increasing the pressure in the cavity to simulate the inhalation action during the breathing process. A temperature sensor and a humidity sensor may also be deployed in the lung simulation module, and a pressure sensor is included in the cavity between the chest cavity simulation module and the lung simulation module. In this way, the temperature sensor can collect the temperature in the cavity of the lung simulation module in real time and send the temperature to the control module 170; the humidity sensor can collect the humidity in the cavity of the lung simulation module in real time and send the humidity to the control module 170; the pressure sensor can collect the pressure in the cavity between the chest cavity simulation module and the lung simulation module in real time and send the pressure to the control module 170. When the control module 170 obtains the humidity of the breathing environment in the lung simulation module, the temperature of the breathing environment in the lung simulation module, and the pressure in the cavity between the chest cavity simulation module and the lung simulation module, it can analyze whether the temperature, humidity, and pressure meet the requirements of the preset detection conditions. If they do, it controls the working state of the oral cavity simulation module 110 to be adjusted from the closed state to the open state, so that when the oral cavity simulation module 110 is in the open state, the flue gas generated after lighting the cigarette enters the lung simulation module through the oral cavity simulation module 110. During or after the test, the detection module 180 can obtain the flue gas particles on the inner wall of the lung simulation module and analyze and detect the flue gas particles to obtain the detection result.

[0034] It should be noted that the double-layer lung module 130 has a double-layer structure. The outer thoracic cavity simulation module is made of a material with high rigidity and modulus of form, providing structural support and airtight closure, simulating the wrapping effect of the thoracic cavity on the lungs; the inner lung simulation module is made of a material with good elasticity and thermal conductivity, and can undergo elastic deformation under the action of external force or internal and external pressure. The entire double-layer lung module 130 has two openings, where the inner opening communicates only with the bronchus or trachea, and the outer opening communicates only with the outside world, and the rest of the joints maintain a sealed structure. At the same time, setting the thoracic cavity simulation module of the outer shell layer can not only prevent air leakage, but also provide a stable environment for sucking cigarettes when the internal air pressure changes.

[0035] It should also be noted that by adjusting the pressure between the two shell layers of the lungs through the motor 160, the size change of the inner space can be realized to simulate the movement of the human diaphragm and complete the cigarette sucking process. At the same time, the size change of the inner space can be realized repeatedly according to requirements. Among them, the running time of the motor 160 during cigarette sucking is controlled according to the data of the pressure sensor, rather than setting a fixed sucking time. Using the data of the pressure sensor to control the switch of the motor 160 is beneficial to improving the temperature stability of the sucked cigarette gas volume.

[0036] In the technical solution provided in this embodiment, by adopting the double-layer lung module, not only can the cigarette sucking process be simulated, but also the exhalation process after sucking can be simulated. By adjusting the pressure in the cavity between the lung simulation module and the thoracic cavity simulation module through the motor, the size change of the inner space is realized, simulating the contraction and expansion effects of the diaphragm during the breathing process, and completing the cigarette sucking-exhaling process. At the same time, through the heat preservation device, the temperature in the cavity between the thoracic cavity simulation module and the lung simulation module is increased to simulate the temperature environment during normal human breathing. Through the humidification module, the humidity in the cavity of the lung simulation module is increased to simulate the humidity environment during normal human breathing, providing a stable cigarette sucking environment similar to the actual temperature and humidity of the human body, which can capture the flue gas particles reaching the lungs more accurately, thereby improving the accuracy of flue gas detection, and solving the problem of poor accuracy in detecting the properties of flue gas in the prior art by sucking the flue gas into the cavity of the syringe and then discharging it from the waste gas pipe to detect the components in the gas exhaled from the lungs to evaluate the flue gas situation in the lungs.

[0037] On the basis of the above embodiment, optionally, the humidifying device 150 is connected to the first end of the air duct; the second end of the air duct is connected to the inner cavity of the lung simulation module, so that the moisture generated by the humidifying device 150 can enter the inner cavity of the lung simulation module to provide a constant humidity environment for sucking and make the lungs have a humidity similar to that of the human body.

[0038] On the basis of the above embodiments, optionally, the respiratory tract simulation module 120 at least includes a nasal cavity simulation structure, a pharynx simulation structure, a main trachea simulation structure, and a bronchus simulation structure.

[0039] In this embodiment, according to the tissue form of the human respiratory system, the nasal cavity simulation structure, the pharynx simulation structure, the main trachea simulation structure, and the bronchus simulation structure can be sequentially connected to form an integral structure with internal communication, which allows the flue gas to enter from the oral cavity simulation module 110, pass through the pharynx and enter the trachea and bronchi in sequence, and then enter the lung simulation module, and allows the flue gas entering the lung simulation module to pass through the main trachea simulation structure, the bronchus simulation structure, the pharynx simulation structure, and then be discharged from the nasal cavity simulation module.

[0040] It should be noted that each part of the lung simulation module can be made by processes such as injection molding, casting, 3D printing, and lathe cutting, and assembled into an integral body through threads, buckles or adhesives, with strong rigidity, so as to be able to self-support to maintain the structure and morphology of its own respiratory tract structure, be able to regularly expand and contract under the adjustment of external air pressure to simulate the breathing movement of the human lung, so as to realize the suction work of cigarettes, and at the same time be able to detect the flue gas of cigarettes.

[0041] On the basis of the above embodiments, optionally, the control module 170 is further configured to control the working state of the motor 160 to be adjusted from the pressurization state to the closed state, control the working state of the nasal cavity simulation structure to be adjusted from the closed state to the open state, and control the working state of the oral cavity simulation module 110 to be adjusted from the open state to the closed state when the pressure reaches the preset pressure, so that the flue gas entering the lung simulation module is discharged after passing through the main trachea simulation structure, the bronchus simulation structure, the pharynx simulation structure, and the nasal cavity simulation module in sequence.

[0042] Among them, the preset pressure can be the pressure reaching the condition of exhaling flue gas.

[0043] In this embodiment, when the control module 170 detects that the pressure in the cavity between the thoracic cavity simulation module and the lung simulation module reaches the preset pressure, it can control the operating state of the motor 160 to be adjusted from the pressurizing state to the closed state, so that the air in the cavity is no longer aspirated. The operating state of the nasal cavity simulation structure is adjusted from the closed state to the open state, and the operating state of the oral cavity simulation module 110 is adjusted from the open state to the closed state, so that after the smoke entering the lung simulation module remains in the lung simulation module, the remaining smoke can pass through the main trachea simulation structure, bronchial simulation structure, pharynx simulation structure and nasal cavity simulation module in sequence, and then be discharged from the smoke detection device, realizing the simulation of breathing cigarette smoke. Exemplarily, after the smoke of the cigarette flows through the middle channel of the respiratory tract simulation module 120 from the oral cavity or nasal cavity, the smoke aerosol entering the lung shell layer can be stored in the lung simulation module. When the smoke aerosol stored in the lung simulation module deforms in the inner layer, it can continue to be stored or discharged from the smoke detection device along the trachea, pharynx, oral cavity and nasal cavity through the trachea.

[0044] It should be noted that the simulation method of breathing cigarette smoke can be carried out periodically. That is to say, based on the smoke detection device of lung respiration, after the smoke generated after lighting the cigarette enters the lung simulation module through the oral cavity simulation module 110, and the smoke entering the lung simulation module passes through the main trachea simulation structure, bronchial simulation structure, pharynx simulation structure and nasal cavity simulation module in sequence and is discharged, the simulation of breathing cigarette smoke can be carried out periodically. Of course, when the temperature of the breathing environment in the lung simulation module is stable at the temperature when the preset detection conditions are reached, and the humidity of the breathing environment in the lung simulation module is stable at the humidity when the preset detection conditions are reached, it is not necessary to adjust the operating states of the humidifying device 150 and the heat preservation device 140, and only the temperature needs to be maintained at a constant temperature and the humidity needs to be maintained at the humidity when the preset detection conditions are reached.

[0045] On the basis of the above embodiment, optionally, the control module 170 is configured to control the temperature of the breathing environment in the lung simulation module to be stable at the temperature when the preset detection conditions are reached, and control the humidity of the breathing environment in the lung simulation module to be stable at the humidity when the preset detection conditions are reached.

[0046] Wherein, the humidity is the relative humidity; the preset detection conditions include that the temperature reaches the preset constant temperature and the relative humidity reaches the preset relative humidity; the preset relative humidity is the ratio of the actual water vapor pressure to the saturated water vapor pressure in the air of the breathing environment at the preset constant temperature. Exemplarily, the preset constant temperature is about 37 °C; the preset relative humidity can be 100%.

[0047] The advantage of this setting is that it can maintain the ambient temperature of the lung-breathing flue gas close to the body temperature (about 37 °C) of the human lung and maintain the ambient humidity of the lung-breathing flue gas close to that of the human lung, thus ensuring that the simulated environment can be close to the breathing state of a real human body and improving the accuracy of flue gas detection during lung breathing.

[0048] On the basis of the above embodiments, optionally, the lung simulation module includes at least three substrates, and the surface of each substrate is covered with a hydrogel mucosa to form a protective film on the surface of the substrate.

[0049] Among them, the first substrate is used to capture nicotine in the flue gas particulate matter; an isopropyl alcohol absorbent solution is covered on the protective film of the first substrate; the second substrate is used to capture tobacco-specific nitrosamines in the flue gas particulate matter; an ammonium acetate absorbent solution is covered on the protective film of the second substrate; the third substrate is used to capture ammonia in the flue gas particulate matter; a sodium hydroxide absorbent solution is covered on the protective film of the third substrate.

[0050] Exemplarily, the substrate includes three substrates a, b, and c. A layer of hydrogel mucosa can be covered on the surface of the substrate respectively, and then an isopropyl alcohol absorbent solution is dropped on the first substrate a to capture nicotine in the flue gas; 0.1 mol·L -1 ammonium acetate absorbent solution is dropped on the second substrate b to capture tobacco-specific nitrosamines in the flue gas; 10 mmol·L -1 sodium hydroxide absorbent solution is dropped on the third substrate c to capture ammonia in the flue gas. Finally, the processed substrates are placed in the inner layer of the lung simulation module. Based on the simulation of the flue gas detection device for cigarette puffing, after the cigarette puffing is completed, the three substrates a, b, and c are taken out from the lung simulation module, and then the hydrogel mucosa is removed from the substrates and tested and analyzed on a machine to obtain the test results. By installing multiple flue gas capture substrates in the inner layer of the lung simulation module and adjusting the chemical composition of the collection substrates, various substances can be captured targeted at the same time, improving the convenience of flue gas particulate matter collection and ensuring the comprehensiveness and accuracy of flue gas detection.

[0051] Embodiment 2

[0052] As an optional embodiment of the above embodiments, in order to make those skilled in the art further clear the technical solutions of the embodiments of the present invention, specific application scenario examples are given. Specifically, the following specific content can be referred to.

[0053] In this embodiment, the method of simulating lung respiration based on the flue gas detection device for flue gas detection may be as follows: First, the control module 170 controls the working state of the nasal cavity opening switch (i.e., the oral cavity simulation module 110) to be in the closed state, the working state of the oral cavity opening switch (i.e., the oral cavity simulation module 110) to be in the closed state, controls the working state of the motor 160 to be in the open state (i.e., the pressurized state), turns on the humidifying device 150 and the heat preservation device 140. When the humidity sensor detects that the humidity of the breathing environment in the lung simulation module is 100% (i.e., the preset relative humidity), and the temperature sensor detects that the temperature of the breathing environment in the lung simulation module is 37 °C (i.e., the preset constant temperature), after the pressure sensor detects that the pressure in the cavity between the thoracic cavity simulation module and the lung simulation module reaches P1 (i.e., the pressure in the preset detection condition), the working state of the oral cavity opening switch is adjusted to the open state, and the cigarette is lit; at this time, the pressure in the thoracic cavity simulation module becomes smaller. To maintain the balance of the internal and external pressures, the outside air enters the interior of the oral cavity of the flue gas detection device through the cigarette filter tip and the inlet of the oral cavity simulation module 110, and then enters the lung simulation module after passing through the nasal cavity simulation structure, the throat simulation structure, the main trachea simulation structure, and the bronchial simulation structure, diffuses and is stored in the lung simulation module, and at this time the lung simulation module expands.

[0054] Further, after the pressure sensor detects that the pressure in the cavity between the thoracic cavity simulation module and the lung simulation module reaches P2 (i.e., the preset pressure), the control module 170 controls the working state of the motor 160 to be adjusted from the pressurized state to the closed state, controls the working state of the nasal cavity opening switch to be adjusted from the closed state to the open state, and controls the working state of the oral cavity opening switch to be adjusted from the open state to the closed state; at this time, the pressure in the thoracic cavity simulation module cavity becomes larger, the cavity of the lung simulation module shrinks, and the flue gas passes through the main trachea simulation structure, the bronchial simulation structure, the throat simulation structure from the cavity of the lung simulation module, and finally is discharged from the flue gas detection device through the nasal cavity simulation module.

[0055] The technical solution provided in this embodiment can not only simulate the smoking process of cigarettes by using a double-layer lung module, but also simulate the exhalation process after smoking. By adjusting the pressure in the cavity between the lung simulation module and the chest simulation module with a motor, the size change of the inner space is realized, simulating the contraction and expansion effects of the diaphragm during the breathing process, and completing the smoking-exhalation process of cigarettes. At the same time, through the heat preservation device, the temperature in the cavity between the chest simulation module and the lung simulation module is increased to simulate the temperature environment during normal human breathing. Through the humidification module, the humidity in the cavity of the lung simulation module is increased to simulate the humidity environment during normal human breathing, providing a stable cigarette smoking environment similar to the actual temperature and humidity of the human body, which can capture the smoke particles reaching the lungs more accurately, thereby improving the accuracy of smoke detection, and solving the problem of poor accuracy in detecting the properties of smoke in the prior art by pumping the smoke into the cavity of a syringe and then discharging it from the waste gas pipeline to detect the components in the gas exhaled from the lungs to evaluate the smoke situation in the lungs.

This embodiment is applicable to detecting the properties of smoke particles deposited in the lungs during the lung respiration process of cigarette smoke. This method can be executed by a device for detecting cigarette smoke based on lung respiration. The device for detecting cigarette smoke based on lung respiration can be implemented in the form of hardware and / or software.
