Description

Technical Field

[0001] The utility model relates to a smoke release control device for tobacco products, in particular to a multi-channel smoke suction and capture device, which can realize the capture and control of smoke aerosols of traditional cigarettes, heated cigarettes and other tobacco products. Background Art

[0002] With the continuous development of the tobacco market, tobacco products are becoming more diversified. New tobacco products, such as heated cigarettes, have become a key development focus for major international tobacco companies and are gradually gaining popularity among consumers. The aerosol generation and delivery mechanisms of heated cigarette smoke differ from those of traditional cigarettes, resulting in significant differences in aerosol morphology and composition.

[0003] Existing smoke extraction and capture devices are typically designed as single-channel capture devices, meaning they can only capture and process one smoke sample at a time. This design simplifies the device's complexity and operational procedures, but when a dual-sample comparison test is required, two separate tests must be performed, increasing testing time and workload. Currently, to achieve dual-sample smoke capture comparison, two independent single-channel capture devices are typically used to capture the two samples separately, with comparisons performed during the subsequent data processing and analysis phase. While this approach is feasible, it increases the complexity of the equipment and the difficulty of operation.

[0004] In order to solve the above problems, the present utility model is proposed. Utility Model Content

[0005] To address the aforementioned issues, the present invention provides a multi-channel smoke extraction and capture device and method. This device enables simultaneous extraction, smoke capture, and comparison of multiple tobacco products. The device offers advantages such as ease of operation, low cost, and portability. To better compare the smoke or smoke aerosols of different tobacco products, the present invention utilizes a portable dual-channel smoking machine to capture and compare the smoke aerosols of cigarettes, heated cigarettes, or other tobacco products, as well as morphological comparison, providing valuable insights for product development and promotion.

[0017] The filter 3-2 is placed on the filter seat 3-7;

[0018] The smoke enters from the smoke inlet 3-6 under the action of the suction force of the suction channel 3-3, and passes through the smoke diffusion channel 1 3-4, the smoke diffusion channel 2 3-8, the filter 3-2 into the suction channel 3-3, and is then discharged into the atmosphere through the three-way valve 2 connecting pipeline.

[0019] Preferably, the Cambridge filter observation window 3-1 is made of highly transparent material.

[0020] Preferably, the cigarette holder 4 comprises a labyrinth ring cap 4-1, a labyrinth ring sealing ring 4-2, a gasket 4-3, a gasket seat 4-4, and a second O-ring 4-5;

[0026] Preferably, the suction piston unit 1 includes a motor 1-1, an electric actuator 1-2, and a first suction piston 1-3. The motor 1-1 is mounted on the top of the body N1 by being fixed to one end of the electric actuator 1-2. The other end of the electric actuator 1-2 is connected to the first suction piston 1-3. The first suction piston 1-3 is connected to the three-way valve 2 through the first air pipe 1-4, that is, the motor 1-1 drives the first suction piston 1-3 to move through the electric actuator 1-2, and different motors 1-1 drive different first suction pistons 1-3 to move to form suction pipelines that do not interfere with each other. When the present invention has two groups of suction and capture components N3, each group of suction and capture components N3 can have an independent suction motor, and different motors 1-1 drive different first suction pistons 1-3 to move to form suction pipelines that do not interfere with each other. The two groups of suction and capture components N3 can achieve suction at different rates at different times, which facilitates comparison between different suction conditions of the same sample.

[0027] or,

[0028] The two suction piston units 1 include a dual-output shaft motor 1-5, a motor mounting bracket 1-6, two drive discs 1-7, two connecting rods 1-8, and two second suction pistons 1-9.

When the present invention has two sets of suction and capture components N3, the two sets of suction and capture components N3 can share one motor, so that the two second suction pistons 1-9 can be driven by one motor to form dual suction channels that do not interfere with each other. The two sets of suction and capture components N3 have the same suction rate at the same time, which is convenient for comparison between different samples under the same suction conditions.

[0033] Specifically, the use process of the device of the utility model is as follows:

[0034] First, insert the cigarette into the cigarette holder and place the filter in the smoke collector. Lighting the cigarette triggers the suction piston unit to draw the first puff of smoke. After passing through the smoke inlet, the smoke first passes through smoke diffusion channel 1 and then through smoke diffusion channel 2. Under the action of suction, the smoke flows into the suction channel, and particulate matter in the smoke is adsorbed by the filter. After the first puff is completed, the suction piston unit performs subsequent puffs according to a specific pattern. At this point, the Cambridge filter observation window can be easily observed, and the color of the filter surface changes with each puff.

[0035] After connecting the device to the power supply and starting it, first insert a traditional cigarette into the cigarette holder on the left side of the device, place the ashtray below in place, and then insert the heated cigarette on the smoking device support block into the cigarette holder on the right side of the device. After the sample is placed, it is necessary to set the smoking parameters on the control panel according to the test requirements. After the parameters are set, the tester needs to use the cigarette lighter to light the cigarette and start the heated cigarette switch, and then click the control panel to start smoking. During the operation of the device, the tester can observe the smoke aerosol capture situation through the highly transparent collector and directly observe the smoke morphology.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. This multi-channel smoke extraction and capture device includes multiple sets of extraction and capture assemblies N3, each corresponding to a cigarette sample. This allows for the extraction and capture of different samples, while also ensuring complementary interference between smoke pipes. This device boasts a simple structure, easy operation, stability, reliability, and low cost. It is widely applicable to the testing of both traditional and heated cigarettes and holds broad market prospects.

[0038] 2. When the present invention has two sets of suction and capture assemblies N3, the two sets of suction and capture assemblies N3 can share a single motor. This allows the two second suction pistons 1-9 to move, forming dual suction channels that do not interfere with each other. The two sets of suction and capture assemblies N3 can simultaneously and at the same rate, facilitating comparison of the same suction conditions between different samples. Alternatively, each set of suction and capture assemblies N3 can have an independent suction motor, with different motors 1-1 driving different first suction pistons 1-3 to form non-interfering suction channels. The two sets of suction and capture assemblies N3 can achieve suction at different rates at different times, facilitating comparison of different suction conditions between the same sample.

[0039] 3. The Cambridge filter observation window 3-1 on the collector of the present invention is made of highly transparent material, which facilitates observation of the smoke aerosol capture during the suction process and direct observation of the smoke morphology.

[0085] like Figure 1-4 As shown: a collection device for collecting smoke particulate matter (i.e., a suction collection assembly N3), comprising a suction piston unit 1, a three-way valve 2, a smoke collector 3, and a cigarette holder 4;

[0086] The suction piston unit 1 is capable of performing suction according to a certain pattern.

[0087] One end of the three-way valve 2 is connected to the suction piston unit 1, one end is connected to the smoke collector 3 through a pipeline, and the other end is connected to the atmosphere through a pipeline.

[0089] The cigarette holder 4 comprises a labyrinth cap 4-1, a labyrinth seal 4-2, a gasket 4-3, a gasket seat 4-4, and a second O-ring 4-5.

[0090] The use process of this utility model is as follows:

[0091] First, insert the cigarette into the cigarette holder and place the filter in the smoke collector. Lighting the cigarette triggers the suction piston unit to draw the first puff of smoke. After passing through the smoke inlet, the smoke first passes through smoke diffusion channel 1 and then through smoke diffusion channel 2. Under the action of suction, the smoke flows into the suction channel, and particulate matter in the smoke is adsorbed by the filter. After the first puff is completed, the suction piston unit performs subsequent puffs according to a specific pattern. At this point, the Cambridge filter observation window can be easily observed, and the color of the filter surface changes with each puff.

[0092] Example 2 has a double suction capture assembly N3

[0093] like Figure 5-8 As shown: A dual-channel smoke extraction and capture device, comprising a body N1, a control panel N2, and two sets of extraction and capture components N3, wherein the extraction and capture components N3 are mounted on the body N1;

[0094] The suction and capture assembly N3 includes a suction piston unit 1, a three-way valve 2, a smoke collector 3 and a cigarette holder 4;

[0095] The suction piston unit 1 is capable of performing suction according to a certain pattern;

[0097] The cigarette holder 4 is connected to the smoke collector 3;

[0098] The control panel N2 is installed on the machine body N1 and is connected to and communicates with the suction controller to control the operation of the suction controller.

[0099] The structure of the suction and capture assembly N3 in this embodiment is consistent with that in Example 1. The portions of the smoke capturer 3 and cigarette holder 4 that are consistent with those in Example 1 are not repeated here. Based on Example 1, the following further details are provided: the suction piston unit 1 includes a motor 1-1, an electric actuator 1-2, and a first suction piston 1-3. The motor 1-1 is mounted on the top of the housing N1 by being fixed to one end of the electric actuator 1-2. The other end of the electric actuator 1-2 is connected to the first suction piston 1-3. The first suction piston 1-3 is connected to the three-way valve 2 via a first air pipe 1-4. Specifically, the motor 1-1 drives the first suction piston 1-3 through the electric actuator 1-2. Different motors 1-1 drive different first suction pistons 1-3, forming independent suction pipelines. Because this embodiment has two sets of suction and capture assemblies N3, two independent suction pipelines are formed, enabling dual-channel simultaneous suction and smoke capture.

[0100] The first suction piston 1-3 can be made of highly transparent material to facilitate direct observation of the smoke state.

[0101] The cigarette holder 4 holds a first sample 4-6 and a second sample 4-8, wherein the first sample 4-6 is a traditional cigarette sample and the second sample 4-8 is a heated cigarette sample. An ashtray 4-7 is provided below the traditional cigarette sample for collecting the ashes of the burned traditional cigarette sample; a smoking device support block 4-9 is provided below the heated cigarette sample for supporting heated cigarette samples of different specifications so as to facilitate insertion into the cigarette holder 4.

[0102] The control panel N2 has a touch function.

[0103] The use process of this utility model is as follows:

[0104] After connecting the device to the power supply and starting it, first insert a traditional cigarette into the cigarette holder on the left side of the device, put the ashtray below in place, and then insert the heated cigarette on the smoking device support block into the cigarette holder on the right side of the device. After the sample is placed, it is necessary to set the smoking parameters on the control panel according to the test requirements. After the parameters are set, the tester needs to use the cigarette lighter to light the cigarette and start the heated cigarette switch, and then click the control panel to start smoking. During the operation of the device, the smoke state can be directly observed through the highly transparent collector. The filter with a high tar content in the smoke generated by the sample to be tested will turn yellow first, and the filter color will be darker when the number of puffs with high tar content is the same.

[0105] Example 3 has a double suction and capture assembly N3, but the double suction and capture assembly N3 shares a driving motor

[0106] like Figure 9-12 As shown: a dual-channel smoke suction and capture device. The device of this embodiment is basically the same as that of Example 2. The difference is that the dual suction and capture components N3 in this embodiment share a drive motor, so the suction piston unit 1 of this embodiment is different from that of Example 2, and an adjustable slide 4-10 is provided under the heated cigarette sample in this embodiment.

[0107] The details are as follows:

[0108] The two suction piston units 1 include a dual-output shaft motor 1-5, a motor mounting bracket 1-6, two drive discs 1-7, two connecting rods 1-8, and two second suction pistons 1-9. The dual-output shaft motor 1-5 is installed inside the body N1 through the motor mounting bracket 1-6. The motor shafts at both ends of the dual-output shaft motor 1-5 are respectively connected to the second suction pistons 1-9 through the drive disc 1-7 and the connecting rod 1-8. The two groups of second suction pistons 1-9 are connected to the two three-way valves 2 through the second air pipe 1-10, that is, the rotation of one dual-output shaft motor 1-5 can simultaneously drive the two groups of second suction pistons 1-9 to move to form dual suction channels that do not interfere with each other.

[0109] The second suction piston 1-9 is made of highly transparent material, which facilitates direct observation of the smoke state.

[0110] An adjustable slide 4 - 10 is provided below the heated cigarette sample, and the smoking device support block 4 - 9 is adjusted by the slide 4 - 10 to support heated cigarette samples of different specifications so that they can be easily inserted into the cigarette holder 4 .

[0111] The use process of this utility model is as follows:

[0112] After connecting the device to the power supply and starting it, first place the traditional cigarette in the cigarette holder on the left side of the device and put the ashtray below in place. Then, by adjusting the slide, the heated cigarette on the smoking device support block can be inserted into the cigarette holder on the right side of the device. After the sample is placed, the smoking parameters need to be set on the control panel according to the test requirements. After the parameters are set, the tester needs to use the cigarette lighter to light the cigarette and start the heated cigarette switch, and then click the control panel to start smoking. During the operation of the device, the tester can observe the changes in the internal filter through the highly transparent collector. The filter with a high tar content in the smoke generated by the sample to be tested will turn yellow first, and the filter color will be darker when the number of puffs with high tar content is the same.
