Description

Technical Field

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

[0002] With the continuous development of the tobacco market, tobacco products have shown a diversified development trend. New tobacco products represented by heated cigarettes have become the key development direction of major international tobacco companies and have gradually won the favor of consumers. The generation and delivery mechanism of heated cigarette smoke aerosol is different from that of traditional cigarettes, and there are significant differences in aerosol morphology and composition.

[0003] The smoke extraction and capture devices in the prior art are usually designed as single-channel capture, which means that they can only capture and process one smoke sample at a time. This design simplifies the complexity and operation process of the device, but when a double-sample control test is required, two tests need to be performed separately, which increases the test time and workload. At present, in order to achieve double-sample smoke capture control, two independent single-channel capture devices are usually used to capture two samples respectively, and the comparison is performed in the subsequent data processing and analysis stage. Although this method is feasible, it increases the complexity of the equipment and the difficulty of operation.

[0004] In order to solve the above problems, the present invention is proposed. Summary of the invention

The motor 1-1 is installed 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 capture components N3, each group of suction capture components N3 can be equipped with 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.

[0033] Specifically, the use process of the device of the present invention is as follows:

[0034] First, insert the cigarette into the cigarette holder and put the filter into the smoke collector. When the cigarette is lit, the suction piston unit is triggered to draw the first puff of smoke. After the smoke passes through the smoke inlet, it first passes through the smoke diffusion channel 1 to the smoke diffusion channel 2. Under the action of suction, the smoke flows to the suction channel, and the particulate matter in the smoke is adsorbed by the filter. After the first puff is completed, the suction piston unit performs subsequent suction according to a certain pattern. At this time, you can easily see through the Cambridge filter observation window that the color of the entire filter surface changes as the number of puffs increases.

[0035] After connecting the device to the power supply and starting it, first insert the 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 utensil 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 high-transparency collector and directly observe the smoke morphology.

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

The multi-channel smoke suction and capture device of the present invention comprises multiple groups of suction and capture components N3, each group of suction and capture components N3 corresponds to a cigarette sample, and the suction and capture of different samples are realized by multiple groups of suction and capture components N3, and the smoke pipelines are complementary and interfered. The present invention has a simple structure, convenient operation, stability and reliability, low cost, can be widely used in the detection of traditional cigarettes and heated cigarettes, and has broad market prospects.

[0038] 2. When the present invention has two groups of suction and capture components N3, the two groups of suction and capture components N3 can use a motor together, so that the two second suction pistons 1-9 can be driven by a motor to form a double suction channel that does not interfere with each other. The two groups of suction and capture components N3 have the same suction rate at the same time, which is convenient for the comparison of the same suction conditions of different samples. It is also possible that each group of suction and capture components N3 has 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 is convenient for the comparison of different suction conditions of the same sample.

[0099] The structure of the suction and capture assembly N3 described in this embodiment is consistent with that in embodiment 1. Among them, the parts of the smoke collector 3 and the cigarette holder 4 that are consistent with those in embodiment 1 are not repeated, and further supplemented on the basis of embodiment 1: the suction piston unit 1 includes a motor 1-1, an electric actuator 1-2, and a first suction piston 1-3.

Because there are two sets of suction and capture assemblies N3 in this embodiment, two suction pipelines that do not interfere with each other are formed, and suction and smoke capture can be performed simultaneously in two channels.

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 with a high tar content will be darker in color when the number of puffs is the same.
