[0031] Embodiment 1

[0032] Figure 1 FIG. is a schematic structural diagram of a flue gas detection device based on the upper respiratory tract provided in Embodiment 1 of the present invention. This embodiment can be applied to detecting the properties of flue gas particles deposited in the upper respiratory tract during the process of inhaling flue gas in the upper respiratory tract. Refer to Figure 1 , the flue gas detection device based on the upper respiratory tract provided in this embodiment includes: a test device 110 and a control device 120 connected based on a physical framework structure; the test device 110 includes an upper respiratory tract simulation model 1101, a three-way air pipe, a nasal solenoid valve, an oral solenoid valve, and a heating device; the control device 120 includes a control module, a detection module, a display panel, a humidifying device, and a power device. The structural composition of the flue gas detection device based on the upper respiratory tract in this embodiment will be specifically described below.

[0033] Refer to Figure 2 , the upper respiratory tract simulation model 1101 includes a nasal cavity simulation module, an oral cavity simulation module, and a pharynx simulation module; the nasal solenoid valve is installed on the air flow channel of the nasal cavity simulation module; the oral solenoid valve is installed on the air flow channel of the oral cavity simulation module; the first end of the three-way air pipe 1102 is connected to the pharynx simulation module, and the schematic structural diagram after the three-way air pipe is connected to the pharynx simulation module can be referred to Figure 3 ; the second end of the three-way air pipe 1102 is connected to the power device; the third end of the three-way air pipe 1102 is connected to the humidifying device, and the schematic structural diagrams of each port of the three-way air pipe can be referred to Figure 4 ; wherein,

[0034] The control module is used to determine a flue gas detection task in response to a task configuration operation on the display panel. Based on the flue gas detection task, it controls the heating device to be in a heating state and the humidifying device to be in a humidifying state to adjust the temperature and humidity of the breathing environment in the upper respiratory tract simulation model 1101; the flue gas detection task includes respiratory parameters corresponding to at least one detection subtask, and the respiratory parameters include the respiratory cycle;

[0035] A control module is configured to obtain the humidity and temperature of the breathing environment in the upper respiratory tract simulation model 1101. When it detects that the temperature and humidity reach the preset detection conditions, based on the breathing parameters in the flue gas detection task, it adjusts the opening and closing states of the nasal solenoid valve and the oral solenoid valve, and adjusts the inhalation parameters and exhalation parameters of the power equipment, so that in each breathing cycle, the flue gas generated by the cigarette at the oral simulation module is inhaled into the upper respiratory tract simulation model 1101 and then exhaled from the nasal cavity simulation module; the nasal solenoid valve is used to control the opening and closing of the nasal cavity simulation module in the upper respiratory tract simulation model 1101; the oral solenoid valve is used to control the opening and closing of the oral simulation module in the upper respiratory tract simulation model 1101; the cigarette is fixed in the oral simulation module based on the cigarette clamping device;

[0036] A detection module is configured to obtain the flue gas particle data on the inner cavity wall of the upper respiratory tract simulation model 1101, detect the flue gas particle data to obtain a detection result, and display the detection result on the display panel.

[0037] Among them, the display panel is used to input configuration information for the detection task, such as detection time, detection frequency, breathing frequency, breathing duration, temperature, humidity setting value, and so on. The heating device can be an electric heater or other types of heaters, and the number of them can be one or multiple. Optionally, the heating device includes at least two electric hot air blowers (devices that convert electrical energy into heat energy, and provide hot air by heating air and blowing it out), and the electric hot air blowers are installed on the inner top layer or the inner bottom side of the test device 110. For example, two can be installed on the inner top layer of the test device 110, and one can be installed on the inner bottom side. The inner top side and the inner bottom side respectively refer to the top and the bottom inside the test device 110. In practical applications, the electric hot air blower consists of three main parts: a blower, a heater, and a control circuit. After the electric hot air blower is powered on, the blower blows air into the heater, and the air passes evenly through the inside and outside of the spiral heating wire. The heat generated after the heating wire is powered on exchanges heat with the cold air, increasing the temperature of the air at the air outlet and raising the temperature of the breathing environment in the upper respiratory tract simulation model 1101 in the test module. The humidifying device can be an ultrasonic humidifier or a steam humidifier. The flue gas detection task can include one or more detection subtasks, and each detection subtask can be executed in parallel. The breathing parameters in each detection subtask can be the same or different. If the breathing parameters are different, then the breathing operations in different detection subtasks are also different. Breathing parameters refer to the parameters involved when inhaling cigarette flue gas from the oral cavity simulation module or exhaling from the nasal cavity simulation module during the simulated smoking process, such as breathing frequency, breathing flow rate, breathing time, breathing cycle, etc. The breathing cycle includes one or more. If there are multiple breathing cycles, then the breathing operations within each breathing cycle in the same detection subtask are the same. The inhalation parameter is used to characterize the parameter of the power device for inhaling the flue gas into the inner cavity of the upper respiratory tract simulation model 1101, and the exhalation parameter is used to characterize the parameter of the power device for exhaling the flue gas from the upper respiratory tract simulation model 1101. The power device includes an electric cylinder pulling a syringe or a motor, etc., which is used to suck or squeeze the gas in the upper respiratory tract simulation model 1101 outward or inward to simulate the process of cigarette sucking. The flue gas particle data can be soot particles such as tar and nicotine deposited on the upper respiratory tract due to cigarette sucking. The preset detection condition can refer to the condition for judging whether the upper respiratory tract environment for cigarette sucking and flue gas testing is reached.

[0038] In this embodiment, the display panel can be a touch screen or a display screen with buttons, and its type can be a liquid crystal display (LCD), a light-emitting diode display (LED), a touch screen, etc. The user can input breathing parameters for inhalation and exhalation, such as inhalation frequency, inhalation flow rate, exhalation flow rate, etc., in the interface of the display panel. When a parameter confirmation control is detected, it is considered that a task configuration operation has been detected. At this time, based on the input breathing parameters, a smoke detection task is generated. Further, based on the smoke detection task, the control module outputs a signal to control the working state of the heating device to be in the heating state, so that the heating device can provide a constant temperature environment for the cigarette smoke inhalation test, making the upper respiratory tract have a temperature approximate to that of the human upper respiratory tract. At the same time, the control module outputs a signal to control the working state of the humidifying device to be in the humidifying state. The humidifying device is connected to the inner cavity of the upper respiratory tract simulation model 1101 through the third end of the three-way air pipe, so that the moisture generated by the humidifying device can enter the inner cavity of the upper respiratory tract simulation model 1101, providing a constant humidity environment for the cigarette smoke inhalation test, making the upper respiratory tract simulation model 1101 have a humidity approximate to that of the human upper respiratory tract. A temperature sensor and a humidity sensor can also be deployed in the upper respiratory tract simulation model 1101. In this way, the temperature sensor can collect the temperature inside the upper respiratory tract simulation model 1101 in real time and send the temperature to the control module; the humidity sensor can collect the humidity inside the upper respiratory tract simulation model 1101 in real time and send the humidity to the control module. When the control module obtains the humidity and temperature of the breathing environment inside the upper respiratory tract simulation model 1101, it can analyze whether the temperature and humidity meet the requirements of the preset detection conditions. Optionally, the preset detection conditions can be that the temperature reaches the temperature of the human upper respiratory tract when sucking a cigarette, and the humidity reaches the humidity of the human upper respiratory tract when sucking a cigarette, etc. If the preset detection conditions are met, based on the breathing parameters in the smoke detection task, within each breathing cycle, by adjusting the opening and closing states of the nasal solenoid valve and the oral solenoid valve, the inhalation parameters and exhalation parameters of the power device can be adjusted, so that the smoke generated by the cigarette at the oral simulation module is inhaled into the upper respiratory tract simulation model 1101 and then exhaled from the nasal simulation module. During or after the test, the detection module can obtain the smoke particle data on the inner cavity wall of the upper respiratory tract simulation model 1101, analyze and detect the smoke particle data, and obtain the detection result. To visualize the detection result, the detection result can be sent to the display panel for display, so that the user can know the cigarette smoke detection situation in real time. At the same time, the display panel can also display the current temperature, humidity, heating and humidifying states in real time. If an abnormal situation occurs (such as too high temperature, abnormal humidity, etc.), the control module can remind the operator through a buzzer or a warning message on the display panel.

[0039] In order to keep the temperature and humidity of the breathing environment in the upper respiratory tract simulation model 1101 at the constant temperature and humidity of the human body, when the detected temperature and humidity reach the preset detection conditions, the temperature can be controlled to be stable at the temperature when the preset detection conditions are reached, and the humidity can be controlled to be stable at the humidity when the preset detection conditions are reached. By maintaining the ambient temperature of the upper respiratory tract flue gas close to the body temperature (about 37 °C) of the human upper respiratory tract and maintaining the ambient humidity during upper respiratory tract breathing flue gas close to the humidity of the human upper respiratory tract, it is ensured that the simulation environment can be close to the real human breathing state, improving the accuracy of flue gas detection during upper respiratory tract breathing.

[0040] In order to accurately collect the flue gas particle data in the upper respiratory tract simulation model 1101, a substrate can be attached to the surface of the airway of the upper respiratory tract simulation model 1101 to achieve in-situ capture of flue gas particles and improve the authenticity of particle capture. In addition, the adsorption substrate can also accurately capture flue gas particles of different particle sizes, providing high-quality sample data for particle composition analysis, thereby improving the accuracy of flue gas detection.

[0041] The technical solution provided by this embodiment connects the test device and the control device based on a physical framework structure, tightly connects the two box structures together to form an integrated flue gas detection device, ensuring the convenience and stability of flue gas detection. The test device includes an upper respiratory tract simulation model, a three-way gas pipe, a nasal solenoid valve, an oral solenoid valve, and a heating device; the control device includes a control module, a detection module, a display panel, a humidifying device, and a power device; the upper respiratory tract simulation model includes a nasal cavity simulation module, an oral cavity simulation module, and a pharynx simulation module; the nasal solenoid valve is installed on the air flow channel of the nasal cavity simulation module; the oral solenoid valve is installed on the air flow channel of the oral cavity simulation module; the first end of the three-way gas pipe is connected to the pharynx simulation module; the second end of the three-way gas pipe is connected to the power device; the third end of the three-way gas pipe is connected to the humidifying device; based on this, the control module can respond to the task configuration operation on the display panel to determine the flue gas detection task, and based on the flue gas detection task, control the working state of the heating device to be in the heating state and control the working state of the humidifying device to be in the humidifying state to adjust the temperature and humidity of the breathing environment in the upper respiratory tract simulation model. At the same time, by obtaining the humidity and temperature of the breathing environment in the upper respiratory tract simulation model, when it is detected that the temperature and humidity reach the preset detection conditions, based on the breathing parameters in the flue gas detection task, adjust the opening and closing states of the nasal solenoid valve and the oral solenoid valve, and adjust the inhalation parameters and exhalation parameters of the power device, so that in each breathing cycle, the flue gas generated by the cigarette at the oral cavity simulation module is inhaled into the upper respiratory tract simulation model and then exhaled from the nasal cavity simulation module, simulating the temperature and humidity environment during normal breathing of the human upper respiratory tract, providing a stable cigarette suction environment approximate to the actual temperature and humidity of the human body, enabling more accurate capture of flue gas particle data reaching the upper respiratory tract, thereby improving the accuracy of flue gas detection, and solving the problem in the prior art that the accuracy of flue gas property detection is poor by pumping flue gas into the syringe cavity and then discharging it from the waste gas pipe to detect the components in the gas exhaled from the upper respiratory tract to evaluate the flue gas situation during upper respiratory tract breathing. Further, the detection result of the flue gas particle data is displayed on the display panel so that the user can know the flue gas detection situation in real time.

[0042] Based on the above embodiment, optionally, the control module includes an inhalation control unit, a pause control unit, and an exhalation control unit; the breathing parameters further include inhalation duration, breathing pause duration, exhalation duration, and inhalation volume; wherein,

[0043] The inhalation control unit is used to control the first opening duration when the opening and closing state of the oral solenoid valve is in the open state, the first closing duration when the opening and closing state of the nasal solenoid valve is in the closed state, and the inhalation parameters of the power device based on the inhalation duration and inhalation volume in the detection subtask during the sequential execution of each detection subtask in the flue gas detection task.

[0044] A pause control unit, configured to control a second closing duration during which an oral electromagnetic valve is in a closed state and a third closing duration during which a nasal electromagnetic valve is in a closed state based on an apnea duration in a detection subtask, and adjust respiratory parameters of a power device;

[0045] An exhalation control unit, configured to control a fourth closing duration during which the oral electromagnetic valve is in a closed state, a second opening duration during which the nasal electromagnetic valve is in an open state, and exhalation parameters of the power device based on an exhalation duration in the detection subtask.

[0046] Wherein, the inhalation duration refers to the duration of controlling the inhalation process. The apnea duration refers to the duration of controlling the pause process between inhalation and respiration. The exhalation duration refers to the duration of controlling the exhalation process. The inhalation volume refers to the volume of gas controlled for each inhalation.

[0047] In this embodiment, when the inhalation control unit executes each detection subtask respectively, it can control a first opening duration during which the oral electromagnetic valve is in an open state to be the inhalation duration and a first closing duration during which the nasal electromagnetic valve is in a closed state to be the inhalation duration according to the inhalation duration and the inhalation volume, and adjust the inhalation parameters of the power device to meet the requirement of the inhalation volume. The pause control unit controls a second closing duration during which the oral electromagnetic valve is in a closed state to be the apnea duration and a third closing duration during which the nasal electromagnetic valve is in a closed state to be the apnea duration based on the apnea duration in the detection subtask, and adjusts the respiratory parameters of the power device to maintain the apnea state, or adjusts the working state of the power device to a pause state or a closed state. The exhalation control unit controls a fourth closing duration during which the oral electromagnetic valve is in a closed state to be the exhalation duration and a second opening duration during which the nasal electromagnetic valve is in an open state to be the exhalation duration based on the exhalation duration in the detection subtask, and adjusts the exhalation parameters of the power device to meet the exhalation requirement and complete the exhalation process.

[0048] Exemplarily, when performing a flue gas detection task, breathing parameters such as suction frequency, suction flow rate, exhalation flow rate, and exhalation time can be set on the display screen according to experimental requirements. Each detection subtask includes at least five breathing parameters: inspiratory duration, apnea duration, expiratory duration, inspiratory volume, and respiratory cycle. Detection subtasks 1, detection subtask, detection subtask 3... detection subtask n can be added in sequence; the time range of the inspiratory duration can be 0 to 60 s, with an error less than 0.1 s. During this period, the power device inhales, the nasal solenoid valve is closed, and the oral solenoid valve is open; the time range of the apnea duration is 0 to 60 s, with an error less than 0.1 s. During this period, the power device does not move, the nasal solenoid valve is closed, and the oral solenoid valve is closed; the time range of the expiratory duration is 0 to 60 s, with an error less than 0.1 s. During this period, the power device exhales, the nasal solenoid valve is open, and the oral solenoid valve is closed; inspiratory volume: the error of the inspiratory volume does not exceed 0.5% of the total inhaled gas volume; respiratory cycle: the inspiratory duration + apnea duration + expiratory duration is one cycle, and the number of cycles is the number of repetitions of one cycle. After the parameter settings are completed, click the start control on the control panel, and the humidification and heating module works. After detecting that the current temperature and humidity meet the requirements, the flue gas detection task is executed in the task order of detection subtask 1, detection subtask 2, detection subtask 3 to detection subtask n in the flue gas detection task.

[0049] The advantage of this setting is that it is convenient to adjust the detection subtasks and breathing parameters according to the flue gas detection requirements on the display panel, improving the convenience of breathing parameter configuration. At the same time, the operator only needs to perform task configuration operations on the display panel, and the subsequent heating and humidification control processes are automatically completed by the control module, improving the convenience and efficiency of operation, reducing the complexity of manual intervention and possible errors, and realizing the high efficiency of flue gas detection.

[0050] It should be noted that it also supports separate opening and closing control of each electrical appliance (solenoid valve, humidifying device, heating device, etc.) in the flue gas detection device, meeting the debugging requirements of flue gas testing and facilitating the maintenance of the device.

[0051] Based on the above embodiments, optionally, the testing device 110 further includes: a flow rate determination module and a pressure determination module; where

[0052] The flow rate determination module is used to detect the flue gas flow rate in the upper respiratory tract simulation model 1101 during each respiratory cycle and send the flue gas flow rate to the control module and the display panel respectively;

[0053] The pressure determination module is used to detect the flue gas flow pressure in the upper respiratory tract simulation model 1101 during each respiratory cycle and send the flue gas flow pressure to the control module and the display panel respectively;

[0054] A display panel for displaying the flue gas flow rate and the flue gas flow pressure;

[0055] A control module for, for each breathing cycle, based on the flue gas flow pressure and the flue gas flow rate received in the current breathing cycle, correcting the inhalation parameters and exhalation parameters of the power device in the current breathing cycle to stabilize the breathing pressure of the breathing environment in the upper respiratory tract simulation model 1101.

[0056] Wherein, the flue gas flow rate refers to the flow velocity and flow rate of the flue gas in the pipeline of the upper respiratory tract simulation model 1101, that is, the flow velocity determination module is used to measure the flue gas flow rate in the upper respiratory tract simulation model 1101.

[0057] In this embodiment, the flow velocity determination module can be based on a gas conduit accessing the inner cavity of the upper respiratory tract simulation model 1101, or installed in the air flow pipeline of the upper respiratory tract simulation model 1101; the air pressure determination module can be based on a gas conduit accessing the inner cavity of the upper respiratory tract simulation model 1101, or installed in the air flow pipeline of the upper respiratory tract simulation model 1101. Optionally, the flow velocity determination module can be a thermal flowmeter (calculating the flow velocity by measuring the heat taken away when the gas flows through the flowmeter), a vortex street flowmeter (measuring the flow velocity by using the vortex street phenomenon generated when the gas flows through a non-streamlined obstacle), an ultrasonic flowmeter (calculating the flow velocity by measuring the propagation time difference of ultrasonic waves in the gas), etc. The flue gas flow pressure can refer to the flue gas flow pressure in the upper respiratory tract simulation model 1101. The air pressure determination module can be a pressure sensor (using a piezoresistive or capacitive pressure sensor to convert the pressure change into an electrical signal output), a mechanical pressure gauge (measuring the pressure through a mechanical structure (such as a bourdon tube)) or other types of pressure gauges. Further, the flow velocity determination module detects the flue gas flow rate in real time and can send the flue gas flow rate to the control module and the display panel. At the same time, the air pressure determination module can detect the flue gas flow pressure in real time and send the flue gas flow pressure to the control module and the display panel. The display panel receives the data of the flow velocity determination module and the air pressure determination module and displays the flue gas flow rate and the flue gas flow pressure in the form of numbers or graphs, providing intuitive monitoring data for the operator and facilitating real-time observation and adjustment of the equipment operation state.
