Description

Technical Field

[0001] This utility model relates to the tobacco industry, and in particular to an aerosol collection device. Background Technology

[0002] In the field of tobacco aerosol research and application, efficient aerosol capture and storage are crucial prerequisites for subsequent analytical experiments. Current aerosol capture methods typically employ a suction-temporary storage-transfer process: first, the aerosol to be collected is drawn into a suction cylinder (e.g., a syringe) for temporary storage using negative pressure; after a certain amount of aerosol has been stored in the suction cylinder, it is then discharged into a collection bag under pressure control, completing the initial collection and storage of the aerosol.

[0003] However, reference Figure 6 Currently, most suction cylinders use a metal body (01), with the lead screw internally mounted within the body (01). The entire suction cylinder is rigidly fixed to the drive motor (04) using bolts (03). Further reference... Figure 7 The cylinder body 01 is also equipped with a teacup-shaped piston 04, a ball screw 05 and a coupling 06. The connection structure is relatively complex. At the same time, due to its large size, heavy weight and multiple bolt fixation, it is not possible to flexibly operate the suction cylinder, making disassembly quite difficult.

[0004] Meanwhile, aerosols may remain in the suction tube and not be completely collected in the gas collection bag. Since the suction tube is difficult to disassemble, the residual aerosols cannot be effectively recycled, directly causing the loss of aerosol samples. On the other hand, the residual aerosol components may also cross-contaminate with newly collected aerosols, further reducing the accuracy of the samples and adversely affecting the reliability of experimental data.

[0005] Furthermore, since the aspiration cylinder cannot be easily disassembled, the extraction solution may remain in the cylinder body and sealing ring gaps for a long time. Existing metal aspiration cylinders and matching sealing rings are difficult to withstand the chemical properties of aerosol extraction solutions and will corrode significantly after long-term contact. This not only shortens the service life of the aspiration cylinder, but may also cause impurities generated by corrosion to mix into subsequent aerosol samples, affecting the purity of the samples.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0050] like Figure 1 As shown, and refer to Figures 2-4 The present invention discloses an aerosol collection device 0, comprising:

[0051] Aerosol generating module 1 is used to ignite or heat cigarette 5 to generate aerosol;

[0052] Aerosol collection module 2, connected to aerosol generation module 1, is used to collect the generated aerosols. It includes a gas phase substance collection unit 20, which includes a syringe 21. The syringe 21 includes a body 210 and a push-pull rod 211.

[0053] The support 3 and the syringe 21 are detachably mounted on the support 3, and the support 3 clamps the syringe body 210;

[0054] The drive module 4 is mounted on the bracket 3 and is detachably connected to the push-pull rod 211, and is used to drive the push-pull rod 211 to move in the cylinder 210.

[0055] In the aerosol collection device 0 of this utility model, the syringe 21, one of the main components of the aerosol collection module 2, has its body 210 and push-pull rod 211 connected to the bracket 3 and the drive module 4 respectively, realizing multi-point fixation of the syringe 21. Therefore, the syringe 21 can be firmly installed in the aerosol collection device 0. At the same time, the body 210 is detachably clamped on the bracket 3, and the push-pull rod 211 is also detachably connected to the drive module 4. When it is necessary to remove the syringe 21, simply release the clamping of the body 210 and disconnect the connection between the push-pull rod 211 and the drive module 4, and the syringe 21 can be taken out of the aerosol collection device 0 as a whole. The disassembly and installation of the syringe 21 are very convenient.

[0056] Based on this, the syringe 21 can be flexibly replaced or maintained as needed without the need for complex disassembly tools, significantly reducing maintenance difficulty and time costs, and improving the versatility and efficiency of the device. Simultaneously, the easy disassembly allows for timely cleaning of the syringe 21, preventing residual aerosol extract from remaining in the syringe and avoiding long-term corrosion, thus extending its service life. Furthermore, residual aerosol in the syringe 21 can be effectively recovered and reused in each experiment, reducing or avoiding aerosol loss and preventing aerosol contamination. This ensures that the sample composition collected each time accurately reflects the current experimental state, providing a reliable sample basis for subsequent qualitative and quantitative analysis and improving the accuracy and repeatability of experimental data.

[0057] Furthermore, the aerosol collection device 0 can also use a detachable syringe 21 to collect and detect the aerosols generated by each puff, thereby enabling the study of the aerosol characteristics of each puff, facilitating the analysis of the dynamic release pattern of tobacco aerosols, optimizing puffing parameters, and further expanding the application of the device in tobacco harm reduction research, product development, and other aspects.

[0058] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the aerosol collection module 2 also includes a particulate matter collection unit 22, which is arranged sequentially with the gaseous matter collection unit 20 along the aerosol flow direction. That is, after the aerosol is generated by the aerosol generation module 1, it first passes through the particulate matter collection unit 22 and then enters the gaseous matter collection unit 20. This fractional separation of particulate and gaseous components in the aerosol provides a precise sample basis for subsequent analysis of the composition and content of the two types of substances, further enhancing the comprehensiveness of the aerosol collection device 0 in analyzing aerosol components.

[0059] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the particulate matter collection unit 22 includes a trap 220 and a fixing plate 221. The cigarette 5 and the trap 220 are respectively installed on both sides of the fixing plate 221. The trap 220 is used to collect particulate matter. The fixing plate 221 serves as a unified installation reference, ensuring that the relative positions of the cigarette and the trap 220 are fixed, and facilitating the quick loading and unloading of the cigarette and the trap 220, thereby improving the stability and efficiency of the experimental operation.

[0060] Furthermore, such as Figure 1 and Figure 2As shown, the aerosol generating module 1 includes a suction nozzle 10, which is mounted on both sides of a fixing plate 221, and a cigarette 5 is inserted into the suction nozzle 10. Preferably, the suction nozzle 10, the cigarette 5, and the collector 220 are all coaxially arranged to form a straight aerosol transport path, reducing flow resistance and avoiding diffusion loss of aerosols during transport, thereby improving the collection efficiency of particulate matter. Furthermore, the unified reference positioning of the fixing plate 221 ensures that the relative positions of the cigarette 5 and the collector 220 are consistent in each experiment, reducing experimental errors caused by installation deviations and improving data repeatability.

[0061] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the gas phase material collection unit 20 also includes a valve 23 and a gas collection bag 24, and the aerosol collection device 0 also includes:

[0062] First pipe 6 connects valve 23 to catcher 220;

[0063] The second pipe 7 connects valve 23 to gas collection bag 24;

[0064] The third pipe 8 connects the valve 23 to the syringe 21. One end of the third pipe 8 is connected to the nozzle of the syringe 21, for example, and can be separated from the nozzle of the syringe 21.

[0065] Among them, the first pipe 6, the second pipe 7 and the third pipe 8 are independently controlled by valve 23 to open and close.

[0066] Through the coordination between valve 23 and various pipelines, the orderly switching of aerosols from collector 220 to syringe 21 for temporary storage, and then from syringe 21 to gas collection bag 24 can be precisely realized, avoiding interference from aerosol mixing in different stages, improving the transfer efficiency and collection purity of gaseous substances, and ensuring the accuracy of subsequent analysis.

[0067] Specifically, valve 23 is, for example, a solenoid valve.

[0068] In the embodiments of this utility model, reference is made to Figures 1-4As shown, the support 3 includes a main support 30, a first cylindrical support 31, and a second cylindrical support 32. The first cylindrical support 31 is fixedly installed on the main support 30, and the second cylindrical support 32 is detachably connected to the first cylindrical support 31. After the first cylindrical support 31 and the second cylindrical support 32 are connected, they can jointly clamp the cylindrical body 210 along the radial direction. Through the detachable connection design of the first cylindrical support 31 and the second cylindrical support 32, a stable clamping can be formed along the radial direction of the cylindrical body 210, preventing the syringe 21 from shifting during the movement of the push-pull rod 211 and ensuring the stability of aerosol collection. At the same time, the syringe 21 can be easily picked up and put away by quickly disassembling the second cylindrical support 32, which further improves the efficiency of device maintenance and experimental operation. It also provides flexible adjustment space for the adaptation of syringes 21 of different specifications, enhancing the versatility of the support 3.

[0069] In the embodiments of this utility model, further reference is made to Figure 5 The first cylindrical support 31 has a first bolt hole and a second bolt hole (not shown in the figure), and the second cylindrical support 32 has a corresponding third bolt hole and a fourth bolt hole (not shown in the figure). For example, the first bolt hole and the second bolt hole are respectively located at both ends of the first cylindrical support 31, and the third bolt hole and the fourth bolt hole are respectively located at both ends of the second cylindrical support 32. After the first cylindrical support 31 and the second cylindrical support 32 are joined, the first bolt hole and the second bolt hole are aligned with the third bolt hole and the fourth bolt hole, respectively, allowing the bolts (e.g.) to be inserted. Figure 1 Bolt b and Figure 5 Bolts b and c) pass through the first and second cylinder supports 31. That is, after the first cylinder support 31 and the second cylinder support 32 are joined, the first bolt hole aligns with the third bolt hole, the second bolt hole aligns with the fourth bolt hole, one bolt passes through the first and third bolt holes, and another bolt passes through the second and fourth bolt holes, thus connecting and fixing the first cylinder support 31 and the second cylinder support 32. The design of the first and second bolt holes, and the third and fourth bolt holes, allows for more balanced force distribution when the first cylinder support 31 and the second cylinder support 32 are joined, avoiding deformation caused by localized stress concentration, and further improving the clamping stability of the cylinder 210. At the same time, this installation method also makes it easier for operators to apply force during assembly and disassembly, simplifying the assembly and disassembly process. Combined with the precise alignment design of the bolts, it ensures the consistency of the position during each connection and installation, further reducing the time cost of maintenance operations and improving the efficiency of experimental operations.

[0070] In the embodiments of this utility model, such as Figures 1-3 As shown, the driver module 4 includes:

[0071] The linear module 40 is fixedly installed on the main support 30 and located below the first cylinder support 31;

[0072] Servo motor 41 is connected to one end of linear module 40 and is used to drive the movement of linear module 40;

[0073] The push-pull rod connector 42 is connected to the linear module 40 and the push-pull rod 211 respectively. The push-pull rod connector 42 can move together with the push-pull rod 211 under the drive of the linear module 40.

[0074] The drive module 4, by fixing the linear module 40 to the main support 30 and placing it below the first barrel support 31, achieves precise alignment with the syringe 21 while making reasonable use of space to avoid interference with other components. The servo motor 41 provides stable power to the linear module 40, accurately controlling the movement speed and stroke of the push-pull rod connector 42, thereby enabling the push-pull rod 211 to move within the barrel 210. This ensures the precise controllability of the aerosol collection and transfer process, reducing aerosol loss or collection deviation caused by unstable drive. At the same time, the push-pull rod connector 42, as an intermediate connecting component, achieves a reliable connection between the linear module 40 and the push-pull rod 211, and facilitates quick disassembly and assembly when changing the syringe 21. Combined with the overall modular design, this further improves the ease of operation and stability of the device, ensuring the accuracy of experimental data.

[0075] Preferably, refer to Figure 1 and Figure 2 The first pipe 6 and the second pipe 7 are arranged coaxially, and the third pipe 8 is perpendicular to the first pipe 6 and the second pipe 7. More preferably, the third pipe 8 extends vertically, the syringe 21 is located below the valve 23, and the main support 30 is located below the first pipe 6 and to the side of the syringe 21. Through the reasonable layout of each component, gravity-assisted aerosol can be used to quickly enter the syringe 21, further improving the collection efficiency of gaseous substances, while avoiding backflow and mixing of aerosols in different pipes, ensuring the purity of collection. In addition, the main support 30 can provide stable support for the syringe 21, avoid the pipe transmission path, avoid spatial interference between components, and make it easier for operators to access the syringe 21 and the drive module 4, simplifying the disassembly, assembly, and maintenance of the syringe 21, further improving the overall space utilization and ease of operation of the device, and providing support for the efficient conduct of experiments.

[0076] In the embodiments of this utility model, reference is made to Figures 1-3The linear module 40 includes two opposing first sidewalls 401 and second sidewalls 402. The first sidewall 401 is fixedly installed on the main support 30, providing a stable installation base for the linear module 40 and preventing it from shaking or shifting during the driving process, thus ensuring the stability of the subsequent push-pull rod 211 movement. The second sidewall 402 is provided with a slide rail 403, on which the push-pull rod connector 42 is installed and can slide on the linear module 40. This provides precise guidance for the sliding trajectory of the push-pull rod connector 42, ensuring that it always moves in a straight line, thereby ensuring the coaxiality of the push-pull rod 211 movement within the cylinder body 210 and ensuring smooth movement. Meanwhile, the slide rail 403 can also reduce the frictional resistance of the push-pull rod connector 42 during movement, making the movement of the push-pull rod 211 more stable and smooth. Combined with the precise drive of the servo motor 41, it can further improve the controllability of the movement speed and stroke of the push-pull rod 211, providing a more reliable guarantee for the quantitative collection and transfer of aerosols, and reducing mechanical wear for the long-term stable operation of the device.

[0077] In the embodiments of this utility model, further reference is made to Figures 1-3 The syringe 21 also includes a round handle 212 located at one end of the push-pull rod 211. The push-pull rod connector 42 is provided with a groove 420, and the round handle 212 is embedded in the groove 420 and secured by a bolt (e.g., Figure 1 Bolt a) is connected to the push-pull rod connector 42. This connection method ensures the alignment of the axes of the push-pull rod connector 42 and the push-pull rod 211, guaranteeing smooth reciprocating movement of the push-pull rod 211 within the cylinder 210 and ensuring the stability of the push-pull rod 211's movement during aerosol collection. Simultaneously, the fitted fit avoids hard friction between the push-pull rod connector 42 and the push-pull rod 211 during disassembly and assembly, reducing wear on the push-pull rod 211 and the push-pull rod connector 42, extending the service life of core components, and lowering the long-term operating cost of the device. The matching design of the fitted fit and bolts allows for easy removal of the syringe 21 by loosening a single bolt. This significantly improves disassembly efficiency by releasing the clamp on the cylinder 210 and loosening the bolt securing the push-pull rod 211. Installing the syringe 21 also only requires clamping the cylinder 210 and fitting the push-pull rod 211, enhancing the device's maintenance efficiency and operational flexibility.

[0078] In the specific embodiments of this utility model, reference is made to Figure 3 The slot 420 has a U-shaped opening, through which the push-pull rod 211 can enter the slot. Simultaneously, the opening size is smaller than the diameter of the round handle 212, allowing the slot 420 to hold the round handle 212. In another specific embodiment of this invention, the slot 420 contains a space for accommodating the round handle 212, which remains within this space after being inserted into the slot 420.

[0079] In a specific embodiment of this utility model, the aerosol collection device 0 is used as follows:

[0080] Insert the filter rod end of cigarette 5 into the suction nozzle 10. Use valve 23 to open the first pipe 6 and the third pipe 8, and close the second pipe 7. Ignite or heat cigarette 5 to generate aerosol. Servo motor 41 drives linear module 40 to rotate. Linear module 40 drives push-pull rod connector 42 to move downward. Under negative pressure, the aerosol enters aerosol collection module 2. The aerosol first passes through collector 220 to collect particulate matter, then flows along the first pipe 6 into the third pipe 8, and then into syringe 21. Subsequently, use valve to close the first pipe 6 and open the second pipe 7. Servo motor 41 drives linear module 40 to rotate. Linear module 40 drives push-pull rod connector 42 to move upward, and the aerosol in syringe 21 is forced into gas collection bag 24. Repeat the above operation until aerosol collection is complete. When it is necessary to remove the syringe 21, first loosen the bolts between the push-pull rod connector 42 and the push-pull rod 211 to release the push-pull rod 211. Then loosen the fixing bolts of the first barrel support 31 and the second barrel support 32, pull out the third tube 8, and release the barrel 210. The syringe 21 can then be removed. After removing the syringe 21, the aerosol extraction solution can be aspirated multiple times to extract the aerosol residue on the inner wall of the syringe 21. The syringe 21 can then be reinstalled or replaced. When it is necessary to collect and test the aerosol from each port, the syringe 21 can be removed after each aspiration and aerosol collection.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
