Description

Technical Field

[0001] This invention belongs to the field of heated cigarette detection technology, specifically relating to a gas collection device and system for collecting heated cigarette smoke. Background Technology

[0002] Existing rotary smoking machines are designed for traditional cigarettes. Because traditional cigarettes are lightweight, up to twenty cigarettes can be placed on the testing platform of the device and automatically lit. The cigarettes smolder and move in a continuous circular motion along with the testing platform. When they reach the smoke collection station, they achieve a continuous process of simulating inhalation and collecting smoke. They then smolder and rotate once more, repeating this process multiple times to achieve the purpose of simulating inhalation and collecting smoke from the entire cigarette at intervals. This device can complete the process of simulating inhalation and collecting smoke at the inhalation station.

[0003] As a relatively new tobacco product, heated cigarettes require the use of existing rotary smoking machines used for traditional cigarettes in order to scientifically evaluate the main components of their smoke, until a mature smoke collection device for heated cigarettes is available in the short term. Furthermore, the proper functioning of a specific cigarette heater is essential for the successful collection of smoke from heated cigarettes.

[0004] To address the above problems, this invention is proposed. Summary of the Invention

[0005] In the process of realizing this invention, the inventors discovered that existing cigarette smoke detection equipment has reserved space for the ash to fall and be collected during the circular motion of traditional cigarettes. Therefore, after heating the cigarettes, various heaters of different sizes and shapes are inserted and then connected to the smoking position for specific smoke collection to complete the smoke collection, leaving enough space to accommodate the auxiliary smoke collection device.

[0006] The purpose of this invention is to incorporate the carrier of this invention into the testing equipment for traditional cigarette sticks, adapting to different specifications and models of heated tobacco devices. This allows the heated cigarette stick to be tested to rotate with the testing platform while being heated by the device, and also enables the heated cigarette stick to be properly connected to the existing testing equipment, so as to facilitate the capture of the simulated smoke during heating.

[0007] The first aspect of the present invention provides a gas collection device for capturing heated cigarette smoke, the gas collection device comprising:

[0008] The gas collection hood 1, the straight duct 2, and the deformable duct 4 are connected in sequence.

[0009] The gas collection hood 1 is detachably connected to the outer periphery of the movable cover A1 of the rotary smoking machine with airtightness.

[0010] One end of the deformable conduit 4 is connected to the straight conduit 2, and the other end of the deformable conduit 4 is an open end. A hook connection structure is provided on the deformable conduit 4.

[0011] The open end of the deformable conduit 4 is a cigarette insertion port 41, which is used to insert the filter of the heated cigarette being tested.

[0012] Preferably, the gas collection hood 1, the straight conduit 2, the deformable conduit 4, and the hook connection structure are integrally formed.

[0013] Preferably, the cross-sectional area of ​​the straight conduit 2 is significantly larger than that of the deformable conduit 4 to prevent the straight conduit 2 from bending.

[0014] Preferably, the outer surface of the straight conduit 2 is provided with a plurality of circumferentially arranged protruding rib structures 21 to resist the bending deformation of the straight conduit 2.

[0015] More preferably, the convex rib structure 21 extends axially along the outer surface of the straight conduit 2.

[0016] The number of the protruding ridge structure 21 is preferably four or more.

[0017] The protruding rib structure 21 is integrally connected to the straight conduit 2 except for the main body portion of the protruding rib structure 21. The cross-section of the main body portion of the straight conduit 2 except for the protruding rib structure 21 is annular.

[0018] Preferably, the hook connection structure is a double earring 3 or a spacer ring 5.

[0019] A second aspect of the present invention provides a heated cigarette smoke collection system, the smoke collection system comprising: a carrier vehicle and the gas collection device described in the first aspect;

[0020] The carrier vehicle includes:

[0021] Carrier plate 8, which is used to support the heating fume;

[0022] A connecting hook 6 is located at the front of the carrier plate 8;

[0023] The vehicle plate 8 is provided with wheels 7 below it, and the front end of the connecting hook 6 is a hook 61, which is used to connect with the hook connection structure of the gas collection device.

[0024] Preferably, the carrier vehicle includes: a fixing component for fixing the heating fume carried on the carrier plate 8.

[0025] Preferably, the number of wheels 7 can be set arbitrarily, for example, 2 to 6.

[0026] Preferably, the number of the connecting hooks 6 is two.

[0027] Preferably, the fastening component is Velcro.

[0028] The terms "front-end" and "back-end" used in this document are relative terms and do not constitute a limitation on the present invention.

[0029] In this invention, "front end" refers to the end closer to the center of the rotary smoke machine, and "rear end" refers to the end farther away from the center of the rotary smoke machine.

[0030] The above technical solutions can be freely combined, provided they do not contradict each other.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The carrier of the present invention is used to adapt to existing rotary smoking machines. By adding the carrier of the present invention to the testing equipment for testing traditional cigarette sticks, it can adapt to heating devices of different specifications and models, so that the heated cigarette stick to be tested can rotate with the testing platform at the same time, and the heated cigarette stick can be normally connected to the existing testing equipment to facilitate the capture of the smoke simulated during heating.

[0033] 2. The carrier vehicle of this invention is convenient and flexible, and can be installed on an existing rotary smoking machine. Compared with specially developed smoke collection equipment for heated cigarettes, the device of this invention is more cost-effective.

[0034] 3. The carrier of the present invention is connected to the gas collection hood 1 via a straight conduit 2, a deformable conduit 4, and a hook connection structure. Due to the inherent adaptability of the elastic deformation of the deformable conduit 4, the height of the carrier does not need to change with the height of the heating fume to adapt to the height of the gas collection hood 1, which also facilitates the traction of the carrier to make circular motion on the fixed disk A6. The straight conduit 2 ensures that the carrier makes circular motion in the relatively central part of the fixed disk A6 without interfering with the inner edge of the fixed disk A6.

[0065] Figure 1 This is a structural schematic diagram of the gas collecting hood and its connecting components according to the first embodiment.

One end of the deformable conduit 4 is connected to the straight conduit 2, and the other end is an open end. The deformable conduit 4 is provided with a hook connection structure.

[0066] The gas collection hood 1, straight conduit 2, deformable conduit 4, and double earrings 3 are all made of one-piece molded silicone material to increase sealing and practicality. The straight conduit 2 has a larger diameter than the deformable conduit 4, therefore it is less prone to deformation. The straight conduit 2 undergoes little or no deformation during use.

[0076] Figure 6 This is a schematic diagram of the connection between the carrier carts and the rotary smoking machine. M1 to M5 represent the carrier carts. After the rotary smoking machine is turned on, the rotating disc A7 rotates, which drives the carrier carts M1 to M6 to make circular motions on the fixed disc A6 through the hook connection structure and the connecting hook 6. In use, the carrier carts M1 to M6 carry the heating device, which contains the heated cigarette to be tested. The filter of the heated cigarette is inserted into the cigarette inlet 41 of the deformable conduit 4 to capture the smoke.

[0077] Figure 7 The diagram shows a partial structural diagram of a rotary smoke extraction machine. Figure A is the front view of the rotary collection platform, Figure B is the partial view of the BB section of the rotary collection platform, Figure C is a structural diagram of a collector on the rotary collection platform, and Figure D is a structural diagram of the smoke collection nozzle component installed at each collection point.

[0078] The smoke collection platform of a rotary smoking machine is a key component used to collect the smoke from traditional cigarettes. It consists of three main parts: a rotating disc A7, an upper collector ring A9, and a lower collector ring A10, all of which rotatably collect the smoke. The rotation is powered by a central shaft. A handle A8 is used for disassembly and removal. A fixed disc A6 on the periphery collects the ash from cigarettes burned during the traditional cigarette testing process. At the outermost edge of the fixed disc A6 is a raised rim A61. The thickness of the rim A61 is the thickness of the metal plate material, and it protrudes approximately 4-5 mm above the fixed disc A6.

[0079] The smoke collection nozzle assembly consists of several main parts: a movable cover A1, a cigarette clamping ring A2, a movable cover A3, a duct A4, and a cigarette clamp holder A5. Twenty circular grooves A91 are evenly distributed around the circumference of the collector's ring A9. At a 45° angle to the tangent at the center of each groove A91, on both sides of the outer circumference of the groove A91 (in the opposite diameter direction), are flat slots A92 into which the guide shaft A51 of the cigarette clamp holder A5 can be inserted. Thus, each groove A91 can accommodate one smoke collection nozzle assembly. A small cigarette receiving hole A21 is located in the center of the rubber cigarette clamping ring A2, which, when the cigarette being tested is inserted, simulates the human mouth "holding" the cigarette. On the cigarette holder A5, on the same plane as the axis of the air duct A4 (rotated 90 degrees), there is a small section of guide shaft A51 on each side. They can be inserted into the flat groove A92 when the cigarette holder A5 is installed into the circular groove A91 of the upper ring A9 of the collector.

[0080] The movable cover A1, cigarette holder ring A2, cigarette receiving hole A21, movable cover seat A3, air guide tube A4, cigarette holder seat A5, guide shaft A51, and positioning hole A52 are collectively called the cigarette holder. After the cigarette holder is installed, pressing it down slightly and rotating it counterclockwise by 45 degrees will rotate the normal direction of the movable cover A1 of the cigarette holder component to a position consistent with the radial direction of each circular groove A91, so that the finally inserted heated cigarettes are arranged radially on the rotary smoking machine.

[0081] During the rotation of this rotary smoking machine, in accordance with the ISO smoking test method commonly used in traditional cigarettes, a 60-second interval is required for each puff, with each puff lasting 2 seconds and totaling 35ml. Therefore, during the test, the computer program controls the smoking machine's transmission system to drive the rotary disc A7 to rotate once per minute, and the smoke is captured when the rotary disc rotates to a specific position.

[0082] When this device is used to detect heated cigarettes, the standard testing method is to take a 2-second puff after a 30-second interval. When the tester selects the corresponding puffing method on the computer configured on the smoking machine, the smoking machine will automatically indicate the installation position on the corresponding collector ring A9 and re-match the rotation speed of the rotating disk A7.

[0083] The carrier vehicle of this invention does not need to cover all 20 workstations; typically, according to the above-described testing method, the carrier vehicle will only be distributed across 3 to 6 workstations. For example... Figure 5 The carrier vehicles M1 to M5 of this invention are installed at five stations on a fixed disc A6. The gas collection hood 1 utilizes the inherent elasticity of its material, with one end detachably and airtightly connected to the outer contour of the upper movable cover A1. A flexible straight rubber tube 2 is fixedly connected to the other end of the gas collection hood 1, and the straight rubber tube 2 is connected to a deformable conduit 4. Then, the heating device and the heated cigarette to be tested are fixed on the carrier plate 8. The smoke generated by the heated cigarette to be tested enters the gas collection hood 1 through the deformable conduit 4 and the straight rubber tube 2, and then enters the smoke collection platform of the rotary smoking machine for collection.
