[0053] Referring to Figure 1 The present application provides a filter performance monitoring system for aerosol components, which comprises a sample fixing module, a sensor module, an analysis module 7, a puffing engine module 5 and a control module 6.

[0054] The sample fixing module comprises an aerosol product holder 1, a first sampling cavity 31 and a second sampling cavity 32. The first sampling cavity 31 is arranged between the smoking segment 21 and the filter segment 22 of the aerosol product, and the second sampling cavity 32 is arranged at the puffing segment 23 of the aerosol product.

[0055] Referring to Figure 2 The aerosol product comprises, from the distal end to the proximal end, the smoking segment 21, the filter segment 22 and the puffing segment 23. The smoking segment 21 generates aerosol after being heated, the user puffs at the puffing segment 23, and the aerosol flows into the user's mouth from the filter segment 22.

[0056] The aerosol product holder 1 is used to standardly fix the smoking segment 21 and the filter segment 22 of the aerosol product to be tested (for example, a cigarette).

[0057] The sensor module is arranged at the first sampling cavity 31 and the second sampling cavity 32, and is used to respectively acquire unfiltered smoke data and filtered smoke data.

[0058] Referring to Figure 3 The first sampling cavity 31 is located at the junction of the smoking segment 21 and the filter segment 22. The cavity is designed with a small sampling port that does not significantly affect the flow of mainstream smoke, and the first sampling cavity 31 is used to extract a small part of unfiltered smoke.

[0059] The second sampling cavity 32 is located at the end of the filter segment 22, that is, the puffing segment 23 of the aerosol product, and the second sampling cavity 32 is used to collect all filtered smoke.

[0060] The sensor module can specifically comprise a first sensor array 41 and a second sensor array 42.

[0061] The first sensor array 41 is arranged at the first sampling cavity 31, and the second sensor array 42 is arranged at the second sampling cavity 32. The two constitute a double-channel synchronous sensor array, and the synchronous sensor array is provided with a physical parameter sensor, a chemical component sensor and an electrochemical sensor.

[0062] In the examples that can be implemented in the present application, the first sensor array 41 and the second sensor array 42 are the same, and each set of sensor array comprises:

[0063] Physical parameter sensor: micro differential pressure / flow sensor and thermocouple temperature sensor, used to measure the flow rate and temperature of the smoke.

[0064] Chemical component sensor: Non-dispersive infrared (NDIR) sensor: for high-precision measurement of CO and CO2.

[0065] Electrochemical sensor: for detecting specific harmful gases, such as nitrogen oxides or formaldehyde.

[0066] The analysis module 7 is used to compare the unfiltered smoke data and the filtered smoke data to generate a puff filtration efficiency curve.

[0067] The puff engine module 5 can be composed of a syringe pump and / or a mass flow controller, and is used to generate a puff profile.

[0068] Specifically, the puff engine module 5 adopts a syringe pump or a mass flow controller (MFC) driven by a precision stepper motor. The engine can be accurately controlled by software to generate a puff profile of any waveform (such as square, bell-shaped) and parameters (volume, flow rate, duration, interval), perfectly simulating various smoking behaviors

[0069] The control module 6 includes a central controller for controlling the start and stop of the puff engine module 5, synchronously acquiring unfiltered smoke data and filtered smoke data, and transmitting the unfiltered smoke data and the filtered smoke data to the analysis module 7.

[0070] Specifically, the control module 6 mainly includes a central controller responsible for synchronously controlling the start and stop of the puff engine. Data from all sensors in the two channels are synchronously collected at a high frequency. The data is transmitted to the analysis module 7 (such as a host computer) through USB or Ethernet for analysis.

[0071] As Figure 4 shown, based on the same inventive concept, the present application also provides a method for monitoring the filtration performance of aerosol components, applied to the filtration performance monitoring system described above. The specific steps of the filtration performance monitoring method can include:

[0072] Step S1: clamping and holding the aerosol product, and simulating puffing of the aerosol product.

[0073] Step S2: synchronously collecting unfiltered smoke data and filtered smoke data of the aerosol product.

[0074] Specifically, the filtration performance monitoring system fixes the aerosol product to be tested by the aerosol product holder 1, and under the condition of simulated puffing (which can be generated by a programmable puffing engine, with a puffing volume of 50 mL, a flow rate of 30 mL / s, and an interval of 30 s), the smoke passes through the first sampling cavity 31 (located at the junction of the smoking section 21 and the filter rod section 22) and the second sampling cavity 32 (located at the end of the filter rod section 22) in turn.

[0075] Step S3: Comparing the unfiltered and filtered smoke data to generate a puff filtration efficiency curve.

[0076] Specifically, the dual-channel synchronous sensor array detects the aerosol in the first sampling cavity 31 and the second sampling cavity 32 in real time to obtain specific numerical values.

[0077] Exemplarily, the specific numerical values can include:

[0078] Physical parameters: flow rate (front: 30 mL / s, rear: 28 mL / s, pressure difference loss 6.7%); temperature (front: 38℃, rear: 35℃, temperature drop 7.9%).

[0079] Chemical components: CO concentration (front: 12 ppm, rear: 7.2 ppm, filtration efficiency 40%); TVOCs concentration (front: 6 mg / m 3 , rear: 3.9 mg / m 3 , filtration efficiency 35%).

[0080] It can be understood that, compared with traditional offline measurement techniques (such as laboratory gas chromatography-mass spectrometry analysis), the present system has significant advantages in real-time performance, dynamic analysis capability, and test efficiency, and specific data comparisons are as follows:

[0081] Measurement real-time performance:

[0082] Traditional method: offline measurement, smoke samples need to be collected and sent to the laboratory for analysis, and data acquisition takes 4-6 hours.

[0083] The present system: real-time synchronous measurement, data acquisition frequency 100 Hz, and real-time output of each data, and the time consumption is only a few seconds.

[0084] Significance: the data acquisition speed is improved by about 1000 times, and immediate decision-making is supported.

[0085] Dynamic performance insight:

[0086] Traditional method: only the cumulative average value of the entire puffing process can be provided.

[0087] The present system: each analysis reveals performance changes.

[0088] Significance: the dynamic resolution is improved to the single-puff level, and the performance evaluation is more accurate.

[0089] Test cost and safety:

[0090] Traditional method: expensive offline equipment is required, and toxic by-products are generated by burning tobacco.

[0091] The present system: integrated benchtop instrument, no need for burning, and avoiding toxic substance handling.

[0092] Significance: significantly improved safety.
