Description

TECHNICAL FIELD

[0001] The present application belongs to the field of aerosol component detection, and particularly relates to an aerosol simulation system. BACKGROUND

[0002] Tobacco smoke is a highly complex dynamic aerosol system, and the particle size distribution characteristics and spatial heterogeneity of chemical components of the tobacco smoke have a decisive influence on the quality of the cigarette and the health risks of the human body. Research shows that the deposition behavior of particulate matter in the respiratory system of cigarette smoke aerosol presents a significant particle size dependence - ultrafine particles (<100 nm) can penetrate into the alveolar region, while larger particles (>1 μm) are mainly deposited in the upper respiratory tract. This differential deposition pattern directly leads to different damage effects of toxic substances (such as polycyclic aromatic hydrocarbons, heavy metals, etc.) carried by particles of different particle sizes on target organs. At the same time, the chemical composition of aerosol particles presents a non-uniform distribution characteristic with particle size, for example, the proportion of volatile organic compounds in nanoscale particles is significantly higher than that in micrometer particles. This component difference directly affects the taste perception and irritation experience during smoking, and therefore, accurate analysis of the particle size-component coupling characteristics of cigarette smoke aerosol has become a core technical requirement of the cigarette industry research and development.

[0003] The particulate matter of smoke aerosol is easy to condense, collide and condense. These characteristics of smoke aerosol can easily cause differences between the particle size and particle size distribution of aerosol particulate matter obtained by testing and the actual aerosol inhaled by a person, thereby affecting the accuracy of the test results. Although the current aerosol testing device has done a good job in testing cigarette smoke aerosol, there are still deficiencies in the precision, dynamics, authenticity and stability of the smoke simulation technology.

[0049] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below in combination with the drawings.

[0050] Please refer to Figure 1 The present application provides an aerosol simulation system, which can include a feed module 1, an atomization module 2, a monitoring module 3 and a feedback control module 12.

[0051] The feed module 1 can include a raw material storage unit 11, a micro-pump array 13 and a feedback control module 12.

[0052] The raw material storage unit 11 is used to store different aerosol raw materials respectively.

[0053] The raw material storage unit includes a first raw material storage unit and at least one second raw material storage unit.

[0054] Specifically, referring to Table 1, the raw material storage unit 11 contains a plurality of liquid storage tanks, which respectively contain base solution (such as glycerol / propylene glycol), nicotine solution, key flavor solution and mother liquor of specific harmful substances (such as formaldehyde, acrolein).

[0055] Table 1: Concentration and ratio of each component mother liquor in the raw material storage unit

[0056]

[0057] The micro-pump array 13 is used to extract the raw materials in the raw material storage unit 11 respectively and form a mixed solution.

[0058] The micro-pump array includes a first micro-pump and at least one second micro-pump.

[0059] The micro-pump array 13 is provided with a micro-fluidic chip 14, which integrates control of multiple independent material channels, each corresponding to one raw material.

[0060] For example, the first raw material storage unit stores a base solution, the second raw material storage unit stores a nicotine solution, and the third raw material storage unit stores a key flavor solution. The first micro-pump is connected to the first raw material storage unit, the second micro-pump is connected to the second raw material storage unit, and the third micro-pump is connected to the third raw material storage unit.

[0061] Referring to Table 2, the micro-pump array 13 includes multiple material channels independently connected to the raw material storage units 11. Each material channel is independently driven by a pump under the drive of the micro-fluidic chip 14 to transport the raw material in the raw material storage unit 11 and form a mixed liquid of aerosol.

[0062] Table 2: Micro-pump array 13 precision test data

[0063]

[0064] Each material channel is independently driven by a high-precision micro-pump (such as a piezoelectric pump or a peristaltic micro-pump). These pumps can achieve nanoliter / minute level flow control, thereby achieving accurate proportioning of each component in the final mixed liquid.

[0065] The control module can control the micro-pump array to extract the first raw material of the first raw material storage unit at a first pumping speed and the second raw material of the second raw material storage unit at a second pumping speed.

[0066] The atomization module 2 atomizes the mixed liquid to form an aerosol and adjusts the temperature and humidity of the aerosol.

[0067] The atomization module 2 includes a micro-atomizer 23 and a temperature and humidity control unit.

[0068] The micro-atomizer 23 is arranged at the outlet of the micro-pump array 13 and is used to atomize the mixed liquid to form an aerosol.

[0069] The micro-atomizer 23 can be a Micro-nebulizer, and the output end of the micro-fluidic chip 14 is directly integrated with the micro-atomizer 23. The atomizer uses Vibrating Mesh or Surface Acoustic Wave (SAW) technology and can atomize the mixed liquid into an aerosol with a controllable particle size distribution (such as 100-500 nanometers) at a low temperature, avoiding thermal decomposition.

[0070] The temperature and humidity control unit includes a micro-humidifier 21 and a micro-heater 22. The micro-humidifier 21 is used to adjust the humidity of the aerosol, and the micro-heater 22 is used to adjust the temperature of the aerosol.

[0071] Exemplarily, the temperature and humidity control unit can be a carrier gas and a temperature and humidity control unit. Pure carrier gas (such as air or nitrogen) is precisely controlled in flow rate by a mass flow controller (MFC) and mixed with the generated aerosol. The mixing chamber is provided with a micro-heater 22 and a humidifier for precisely regulating the temperature and relative humidity of the final output aerosol, so as to be consistent with the real smoke state.

[0072] The monitoring module 3 is used for monitoring the physical properties of the aerosol.

[0073] Specifically, the monitoring module 3 comprises a shunt sampling port 31 and a feedback control module 12. The shunt sampling port 31 is provided with a micro-sensor array for monitoring the physical properties of the aerosol.

[0074] The feedback control module 12 comprises a feedback controller 34 for controlling the flow rate and output position of the micro-pump array 13 and making secondary adjustment to the micro-pump array 13 according to the feedback information of the monitoring module 3.

[0075] Specifically, the feedback controller 34 adjusts the output of the micro-pump array 13 and the MFC in real time and dynamically through a PID (proportional-integral-derivative) control algorithm to eliminate errors and ensure that the output aerosol of the main path is consistent with the target profile height.

[0076] The aerosol simulation system is configured to generate a simulated aerosol according to the following steps:

[0077] Step S1: Obtain an aerosol formula and extract aerosol raw materials according to the aerosol formula.

[0078] Step S2: Mix and atomize the aerosol raw materials according to a preset ratio to generate an aerosol.

[0079] Exemplarily, referring to Table 3, the aerosol simulation system of the present application extracts corresponding mother liquor from the raw material storage unit according to the user-set smoke formula (such as nicotine concentration 2mg / m 3 , formaldehyde concentration 0.5mg / m 3 ) through a multi-channel microfluidic sampling module.

[0080] The precise micro-pump array 13 delivers each component to the microfluidic chip 14 at a nanoliter level of precision (such as nicotine solution flow rate 20nL / min) to form a mixed solution of a specific ratio.

[0081] Subsequently, the mixed solution enters the integrated micro-atomizer 23 and is atomized under the condition of a vibration screen frequency of 120kHz to generate an aerosol with a particle size of 100-500nm.

[0082] Table 3: Micro-atomizer 23 aerosol particle size distribution data

[0083]

[0084] Step S3: Adjust the ambient temperature and humidity of the aerosol, and monitor the physical properties of the obtained aerosol.

[0085] Specifically, by the temperature and humidity control unit, the aerosol simulation system adjusts the physical parameters of the aerosol to the target value, for example, the temperature is adjusted to 40℃, and the relative humidity is adjusted to 65%, to simulate the characteristics of real smoke at different puffing stages.

[0086] Step S4: Determine whether the deviation value of the physical properties of the aerosol exceeds the preset threshold:

[0087] If yes, dynamically adjust the micropump array 13 and / or the atomizer module based on the PID algorithm, and re-monitor the physical properties of the aerosol.

[0088] The monitoring module 3 draws a small amount of aerosol through the shunt sampling port 31, and uses a micro sensor array (such as a light scattering particulate matter counter 32 and a PID sensor 33) to measure key parameters in real time to obtain specific values.

[0089] For example: the actual value of nicotine concentration is 2.01 mg / m 3 (error 0.5%), the actual value of formaldehyde concentration is 0.49 mg / m 3 (error 2%), and the particle size distribution of 200-300 nm accounts for 34.8% (close to the target value of 35%).

[0090] The feedback controller 34 dynamically adjusts the micropump flow or the atomizer parameters based on the deviation of the monitoring data from the target value through the PID algorithm, to ensure that the chemical composition and physical properties of the output aerosol are highly consistent with the set value, with an error controlled within 0.1%-0.3%.

[0091] It can be understood that compared with traditional smoke simulation technology (such as macroscopic pump and ultrasonic atomizer), the present system has significant advantages in control accuracy, dynamic response and simulation reality, and the specific data comparison is as follows:

[0092] Component control accuracy:

[0093] Traditional method: macroscopic pump control accuracy is low, component concentration error range ±10%-15%

[0094] The present system: microfluidic technology combined with closed-loop feedback, component concentration error controlled within ±0.5%

[0095] Significance: control accuracy is improved

[0096] Dynamic response speed:

[0097] Traditional method: long response time of macroscopic equipment, 5-10 seconds are needed to adjust the component concentration, and it is impossible to simulate the dynamic changes of real smoke.

[0098] The present system: the response time of the micro-pump array 13 is less than 0.5 seconds, the component concentration can be adjusted in real time, and the dynamic process from ignition to extinguishment can be simulated.

[0099] Significance: dynamic response speed is improved, and the simulation authenticity is significantly enhanced.

[0100] It can be understood that the aerosol simulation system of the present application has the advantages of high precision and repeatability, dynamic simulation, high flexibility and decoupling research, safety, high efficiency, and low cost.

[0101] Specifically, high precision and repeatability: microfluidic technology improves the component control precision by several orders of magnitude. The closed-loop feedback system eliminates errors caused by environmental changes and system drift, ensuring strict consistency of each experiment.

[0102] Dynamic simulation can be achieved: for the first time, the dynamic chemical and physical changes of real smoke during the entire smoking process can be reproduced with high fidelity, making the research more realistic.

[0103] High flexibility and decoupling research: researchers can freely "design" smoke, for example, only change the nicotine concentration while keeping all other parameters unchanged, to achieve precise research on the influence of a single variable, which cannot be achieved with real tobacco.

[0104] Safety, high efficiency, and low cost: avoid handling complex and toxic real tar. The system has high automation, greatly shortens the experimental preparation time, and reduces the consumption of expensive standard substances.

[0105] Wide application field: not only can be used for traditional tobacco research, but also is an ideal platform for electronic cigarette oil formula optimization, aerosol analysis of heat-not-burn products, and research and development of various inhalation drug delivery systems.
