Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, and specifically relates to a device for testing the combustion performance of cigarettes. Background Technology

[0002] In the tobacco manufacturing industry, cigarettes are typically tested, such as for tobacco density, surface pattern, and combustion performance. These tests are designed to improve the consumer's smoking experience and thus enhance the quality of the cigarettes.

[0003] Currently, when testing the combustion performance of cigarettes, the cigarette is usually clamped directly onto a mounting frame, and then inhaled through a suction device to simulate the process of a consumer smoking. A vibrator is installed to shake the cigarette and dislodge the ash, thereby observing the combustion performance of the cigarette. However, the existing vibrator cannot simulate the actual action of a consumer shaking off ash during smoking, and the test results obtained are not objective and practical. Summary of the Invention

[0004] The purpose of this invention is to provide a cigarette combustion performance testing device to solve the problem that existing vibrators cannot simulate the actual action of consumers shaking off cigarette ash during smoking, and the test results obtained are not objective and practical.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A cigarette combustion performance testing device includes a suction mechanism, a clamping mechanism, and a tapping mechanism. The suction mechanism includes a drive assembly and a suction assembly, with the drive assembly located behind the suction assembly. The clamping mechanism is connected to the suction assembly, and the tapping mechanism is located on one side of the clamping mechanism. The tapping mechanism includes a second mounting base, a second cover plate, a second telescopic motor, and a tapping assembly. The second mounting base is located on one side of the cigarette, and the second cover plate is mounted on the second mounting base. A support frame is mounted on the second cover plate, and the second telescopic motor is mounted inside the support frame. A second control panel is mounted on the support frame, and the second control panel and the second telescopic motor are electrically connected. The output shaft of the second telescopic motor passes through the second cover plate and is located inside the second mounting base. The tapping assembly includes a rack, a first gear, a second gear, a first connecting arm, and a second connecting arm. A second sliding groove is formed on the second mounting base, and a second sliding groove is fixedly mounted on the rack. The second slider is slidably installed in the second groove. The output shaft of the second telescopic motor is fixedly connected to one end of the rack. A first rotating rod is rotatably installed in the second mounting base. A first gear is fixedly installed on the first rotating rod and meshes with the rack. A first connecting sleeve is fixedly installed on the first rotating rod. A first connecting arm is fixedly installed on the first connecting sleeve. A first spring is fixedly provided at the end of the first connecting arm. A third through groove is opened in the second mounting base at the positions of the first and second connecting arms. The first and second connecting arms pass through the third through groove. A second rotating rod is rotatably installed in the second mounting base. The second rotating rod is located below the first rotating rod. A second gear is fixedly installed on the second rotating rod. A second connecting sleeve is fixedly installed on the second rotating rod. A second connecting arm is fixedly installed on the second connecting sleeve. A second spring is fixedly installed at the end of the second connecting arm.

[0007] Furthermore, both the first and second gears are sector gears. This configuration ensures that when the rack moves down, the first gear rotates, causing the first connecting arm to strike the cigarette. When the rack moves up, the first connecting arm will not strike the cigarette. Similarly, when the rack moves to the second gear, the second gear rotates, causing the second connecting arm to bounce the cigarette. When the rack moves up, the second connecting arm will not bounce the cigarette. Thus, the first and second connecting arms only shake off ash when the rack moves down, which better reflects the process of shaking off ash when smoking.

[0008] Furthermore, the first gear and the second gear are located on the same axis. This arrangement ensures that the up-and-down movement of the rack can drive the first gear and the second gear to rotate.

[0009] Furthermore, both the first and second springs are made of silicone and are curved. This design avoids damaging the cigarette paper on the surface, thus affecting the combustion performance test.

[0010] Further specifying, the drive assembly includes a first mounting base, a first telescopic motor, and a first control panel. The first telescopic motor is fixedly mounted on the first mounting base, and the first control panel is mounted on one side of the first mounting base. The first control panel and the first telescopic motor are electrically connected. A first transmission rod is fixedly connected to the output shaft of the first telescopic motor, and a first baffle is fixedly mounted at the end of the first transmission rod. The first baffle is located inside the suction assembly. With this configuration, the telescopic length and telescopic speed of the output shaft of the first telescopic motor can be adjusted through the first control panel, thereby controlling the telescopic length and telescopic speed of the first baffle inside the suction assembly, and thus controlling the air intake and air intake time.

[0011] Further defining the suction assembly, it includes a first outer shell, an inner shell, an arc-shaped plate, and a sealing assembly. A mounting bracket is fitted onto the outer wall of the first outer shell, and the first outer shell is fitted between a first mounting base and the mounting bracket. A first baffle is fitted inside the first outer shell. The inner shell has an L-shaped cross-section and is fixedly connected to the inner wall of the first outer shell. There is a gap between the inner shell and the first outer shell. The arc-shaped plate is slidably installed between the inner shell and the first outer shell. A first groove is formed on the inner shell. A first slider is fixedly installed on the arc-shaped plate, and the first slider is slidably installed within the first groove. A fixing block is fixedly installed on the arc-shaped plate. A first through slot is formed on a baffle plate, through which the fixing block passes. A first groove is formed at the end of the fixing block, and a first spring is installed in the first groove. A wedge-shaped locking block is also installed in the first groove. One end of the first spring is fixedly connected to the bottom of the first groove, and the other end is fixedly connected to one end of the locking block. The first outer shell is transparent, and multiple first through holes are formed on the inner shell. Multiple second through holes are formed on the arc-shaped plate, and multiple third through holes are formed on the first outer shell. The sealing assembly includes two mounting plates, two sleeves, a rotating shaft, a rotating column, and a first cover plate. The two mounting plates... The inner shell is fixedly installed on the inner wall of the first outer shell and is opposed to each other. The rotating shaft is rotatably installed between two mounting plates, and the rotating column is rotatably installed in the middle of the rotating shaft. Two sleeves are respectively rotatably installed on the rotating shaft and located at both ends of the rotating column. A connecting plate is fixedly installed between the rotating column and the first cover plate. The first cover plate is convex and fits onto the inner shell. A first connecting column is fixedly installed at one end of the arc-shaped plate, and a second connecting column is fixedly installed at the bottom of the first cover plate. A connecting rope is fixedly fastened between the first and second connecting columns. A second passage is opened in the inner shell at the position of the first connecting column. The connecting rope passes through the second through groove. This arrangement allows the first baffle to move, driven by the movement of the first baffle, which in turn moves the arc-shaped plate. When the arc-shaped plate abuts against the end of the inner shell furthest from the first mounting base, the first, second, and third through holes are connected, allowing the smoke inside the first outer shell to be discharged before the next suction cycle after the first baffle has finished suctioning. The connecting rope connects the arc-shaped plate and the first cover plate, so that when the arc-shaped plate moves on the first sliding groove, it can drive the rotation of the first cover plate, thereby opening and closing the inner shell, and subsequently opening and closing the first outer shell. This, in conjunction with the movement of the first baffle, controls the suction time and volume of air intake.

[0012] Furthermore, a sealing sleeve is fixedly provided on the first baffle. This arrangement ensures that the first baffle is tightly attached to the inner wall of the first housing, preventing air leakage when the first baffle moves within the first housing.

[0013] Further, the inner shell has a threaded hole at one end of the first sliding groove, a bolt passes through the threaded hole, the bolt passes through the first slider, and the other end of the bolt is located outside the first sliding groove. With this arrangement, the cooperation of the bolt, the threaded hole, the first slider, the first sliding groove, and the arc plate allows the arc plate to slide within the first sliding groove without sliding out of the first sliding groove.

[0014] Furthermore, a limiting groove is provided on the rotating column, and the connecting rope is locked in the limiting groove. This arrangement prevents the connecting rope from moving axially and affecting the opening and closing of the first cover plate.

[0015] Further specifying, the clamping mechanism includes a second outer shell and a clamping assembly. A second flange is fixedly installed at one end of the second outer shell, and a first flange is fixedly installed at one end of the first outer shell. A sealing ring is installed between the first flange and the second flange. The clamping assembly includes a first annular ring and a second annular ring, both of which are concave structures. The first annular ring is fixedly disposed on the inner wall of the second outer shell, and the second annular ring is sleeved inside the first annular ring. Multiple fixing rods are fixedly installed inside the second annular ring, and a second spring is sleeved on each fixing rod. One end of the second spring is fixedly connected to the bottom of the second annular ring, and the other end is fixedly connected to the bottom of the first annular ring. The second annular ring is made of rubber. This arrangement prevents air leakage between the first flange and the second flange during suction by using the sealing ring. By expanding the center of the second annular ring, the second annular ring is squeezed into the first annular ring, allowing the center of the second annular ring to hold cigarettes of different sizes.

[0016] The invention employing the above technical solution has the following advantages:

[0017] 1. The extension and retraction speed of the output shaft of the second telescopic motor can be adjusted through the second control panel, thereby controlling the frequency and force of the first and second connecting arms tapping the cigarette, which is more in line with the action of shaking off the ash when a consumer smokes, so that the detected cigarette combustion performance is more in line with the actual situation.

[0018] 2. The extension length and speed of the output shaft of the first telescopic motor can be adjusted via the first control panel, thereby controlling the extension length and speed of the first baffle within the suction assembly. A locking block abuts against the first baffle, allowing the movement of the first baffle to move the arc-shaped plate. When the arc-shaped plate abuts against the end of the inner shell furthest from the first mounting base, the first, second, and third through holes connect, allowing the smoke inside the first outer shell to be expelled before the next suction cycle after suction. A connecting rope connects the arc-shaped plate and the first cover plate, allowing the movement of the arc-shaped plate on the first slide groove to move the first cover plate, thereby opening and closing the inner shell, and subsequently opening and closing the first outer shell. This, in conjunction with the movement of the first baffle, controls the suction volume and suction time.

[0019] 3. By using a sealing ring, air leakage between the first and second flanges is prevented during suction; by enlarging the center of the second annular ring, the second annular ring is pressed into the first annular ring, allowing different sizes of cigarettes to be placed in the center of the second annular ring.

Detailed Implementation

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0035] like Figures 1-9As shown, a cigarette combustion performance testing device of the present invention includes a suction mechanism, a clamping mechanism 3 and a tapping mechanism 4. The suction mechanism includes a driving component 1 and a suction component 2. The driving component 1 is located behind the suction component 2. The clamping mechanism 3 is connected to the suction component 2. The tapping mechanism 4 is located on one side of the clamping mechanism 3.

[0036] The drive assembly 1 includes a first mounting base 11, a first telescopic motor 12, and a first control panel 13. The first telescopic motor 12 is fixedly mounted on the first mounting base 11, and the first control panel 13 is mounted on one side of the first mounting base 11. The first control panel 13 is electrically connected to the first telescopic motor 12, and the telescopic length and telescopic speed of the output shaft of the first telescopic motor 12 can be adjusted through the first control panel 13. A first transmission rod 121 is fixedly connected to the output shaft of the first telescopic motor 12, and a first baffle 23 is fixedly mounted at the end of the first transmission rod 121. The first baffle 23 is located inside the suction assembly 2.

[0037] The suction assembly 2 includes a first outer shell 21, an inner shell 27, an arc-shaped plate 25, and a sealing assembly. A mounting bracket 14 is fitted onto the outer wall of the first outer shell 21, and the first outer shell 21 is fitted between the first mounting base 11 and the mounting bracket 14 to prevent the suction assembly 2 from loosening during operation. A first baffle 23 is fitted inside the first outer shell 21, and a sealing sleeve 24 is fixedly provided on the first baffle 23. The sealing sleeve 24 keeps the first baffle 23 in close contact with the inner wall of the first outer shell 21, preventing air leakage when the first baffle 23 moves within the first outer shell 21. The inner shell 27 has an L-shaped cross-section and is fixedly connected to the inner wall of the first outer shell 21. There is a gap between the inner shell 27 and the first outer shell 21. The arc-shaped plate 25 is slidably installed between the inner shell 27 and the first outer shell 21. A first sliding groove 274 is provided on the inner shell 27, and a first slider 251 is fixedly installed on the arc-shaped plate 25. The first slider 251 is slidably installed within the first sliding groove 274. The inner shell 27 has a threaded hole 272 at one end of the first slide groove 274. A bolt 275 passes through the threaded hole 272 and passes through the first slider 251. The other end of the bolt 275 is located outside the first slide groove 274. Through the cooperation of the bolt 275, the threaded hole 272, the first slider 251, the first slide groove 274, and the arc plate 25, the arc plate 25 can slide within the first slide groove 274 without sliding out of the first slide groove 274. A fixing block 26 is fixedly installed on the arc-shaped plate 25. A first through groove 231 is provided on the first baffle 23. The fixing block 26 passes through the first through groove 231. A first groove 261 is provided at the end of the fixing block 26. A first spring 262 is installed in the first groove 261. A locking block 263 is installed in the first groove 261. The locking block 263 is wedge-shaped. One end of the first spring 262 is fixedly connected to the bottom of the first groove 261, and the other end is fixedly connected to one end of the locking block 263. The locking block 263 abuts against the first baffle 23, so that the movement of the first baffle 23 can drive the arc-shaped plate 25 to move. The first outer shell 21 is transparent to facilitate the connection and installation of the arc-shaped plate 25 and the first baffle 23.

[0038] The inner shell 27 has multiple first through holes 271, the arc plate 25 has multiple second through holes 253, and the first outer shell 21 has multiple third through holes 201. When the arc plate 25 abuts against the end of the inner shell 27 away from the first mounting base 11, the first through holes 271, the second through holes 253 and the third through holes 201 are connected, so that the smoke in the first outer shell 21 can be discharged when the first baffle 23 needs to perform the next suction after suction.

[0039] The enclosure assembly includes two mounting plates 28, two sleeves 281, a rotating shaft 29, a rotating column 282, and a first cover plate 283. The two mounting plates 28 are fixedly mounted on the inner wall of the first outer shell 21 and are opposite to each other. The rotating shaft 29 is rotatably mounted between the two mounting plates 28, and the rotating column 282 is rotatably mounted in the middle of the rotating shaft 29. The two sleeves 281 are respectively rotatably mounted on the rotating shaft 29 and located at both ends of the rotating column 282 to prevent axial displacement of the rotating column 282. A connecting plate 284 is fixedly installed between the rotating column 282 and the first cover plate 283. The first cover plate 283 is convex and fits onto the inner shell 27, sealing the inner shell 27. A first connecting post 252 is fixedly installed at one end of the arc-shaped plate 25, and a second connecting post 285 is fixedly installed at the bottom of the first cover plate 283. A connecting rope 6 is fixedly fastened between the first connecting post 252 and the second connecting post 285. A second through groove 273 is opened at the position of the first connecting post 252 in the inner shell 27. The connecting rope 6 passes through the second through groove 273, connecting the arc-shaped plate 25 and the first cover plate 283. When the arc-shaped plate 25 moves on the first sliding groove 274, it can drive the rotation of the first cover plate 283, thereby opening and closing the inner shell 27, and then opening and closing the first outer shell 21. A limit groove 286 is opened on the rotating post 282, and the connecting rope 6 is locked in the limit groove 286 to prevent the connecting rope 6 from moving axially and affecting the opening and closing of the first cover plate 283.

[0040] The clamping mechanism 3 includes a second housing 31 and a clamping assembly. A second flange 32 is fixedly installed at one end of the second housing 31, and a first flange 22 is fixedly installed at one end of the first housing 21. A sealing ring 221 is installed between the first flange 22 and the second flange 32, connecting the first housing 21 and the second housing 31. The sealing ring 221 prevents air leakage between the first flange 22 and the second flange 32 during suction. The clamping assembly includes a first annular ring 33 and a second annular ring 34, both of which are concave structures. The first annular ring 33 is fixedly disposed on the inner wall of the second housing 31, and the second annular ring 34 is fitted inside the first annular ring 33. Multiple fixing rods 35 are fixedly installed inside the second annular ring 34. A second spring 36 is sleeved on the fixing rod 35. One end of the second spring 36 is fixedly connected to the bottom of the second annular ring 34, and the other end is fixedly connected to the bottom of the first annular ring 33. The second annular ring 34 is made of rubber. By expanding the center of the second annular ring 34, the second annular ring 34 is squeezed into the first annular ring 33, so that cigarettes of different sizes can be placed in the center of the second annular ring 34.

[0041] The tapping mechanism 4 includes a second mounting base 41, a second cover plate 44, a second telescopic motor 47, and a tapping assembly. The second mounting base 41 is located on one side of the cigarette stick 5. The second cover plate 44 is mounted on the second mounting base 41, and a support frame 42 is mounted on the second cover plate 44. The second telescopic motor 47 is mounted inside the support frame 42, and the output shaft of the second telescopic motor 47 passes through the second cover plate 44 and is located inside the second mounting base 41. The tapping assembly includes a rack 48, a first gear 492, a second gear 494, a first connecting arm 45, and a second connecting arm 46. A second sliding groove 402 is provided on the second mounting base 41. A second slider 481 is fixedly mounted on the rack 48 and slidably mounted in the second sliding groove 402. The output shaft of the second telescopic motor 47 is fixedly connected to one end of the rack 48, so that the rack 48 can move within the second sliding groove 402 under the drive of the second telescopic motor 47. A first rotating rod 49 is rotatably mounted inside the second mounting base 41. A first gear 492 is fixedly mounted on the first rotating rod 49 and meshes with a rack 48. A first connecting sleeve 493 is fixedly mounted on the first rotating rod 49, and a first connecting arm 45 is fixedly mounted on the first connecting sleeve 493. A first spring piece 451 is fixedly provided at the end of the first connecting arm 45. A third through groove 401 is provided in the second mounting base 41 at the positions of the first connecting arm 45 and the second connecting arm 46, through which the first connecting arm 45 and the second connecting arm 46 pass. By moving the rack 48 up and down, the first gear 492 is driven to rotate, thereby causing the first connecting arm 45 to strike the cigarette 5 from above, shaking off the ash from the cigarette 5, and thus testing the combustion performance of the cigarette 5. A second rotating rod 491 is rotatably mounted inside the second mounting base 41. The second rotating rod 491 is located below the first rotating rod 49. A second gear 494 is fixedly mounted on the second rotating rod 491. A second connecting sleeve 495 is fixedly mounted on the second rotating rod 491. A second connecting arm 46 is fixedly mounted on the second connecting sleeve 495. A second spring 461 is fixedly mounted at the end of the second connecting arm 46. By moving the rack 48, the second gear 494 can mesh with the rack 48. When the rack 48 moves up and down, it drives the second gear 494 to rotate, thereby driving the second connecting arm 46 to bounce the cigarette 5 from the side, shaking off the ash, and thus testing the combustion performance of the cigarette 5.

[0042] The first gear 492 and the second gear 494 are sector gears. Therefore, when the rack 48 moves downward, the first gear 492 rotates, which in turn drives the first connecting arm 45 to strike the cigarette 5. When the rack 48 moves upward, the first connecting arm 45 does not strike the cigarette. Similarly, when the rack 48 moves to the second gear 494, the second gear 494 rotates, which in turn drives the second connecting arm 46 to flick the cigarette 5. When the rack 48 moves upward, the second connecting arm 46 does not flick the cigarette 5. By ensuring that the first connecting arm 45 and the second connecting arm 46 only shake off the ash when the rack 48 moves downward, the process of shaking off ash when smoking is more consistent with the natural process of a person shaking off cigarette ash.

[0043] The first gear 492 and the second gear 494 are located on the same axis, ensuring that the up and down movement of the rack 48 can drive the first gear 492 and the second gear 494 to rotate.

[0044] A second control panel 43 is installed on the support frame 42. The second control panel 43 is electrically connected to the second telescopic motor 47. The telescopic speed of the output shaft of the second telescopic motor 47 can be adjusted through the second control panel 43, thereby controlling the frequency and force of the first connecting arm 45 and the second connecting arm 46 striking the cigarette stick 5.

[0045] The first spring 451 and the second spring 461 are both made of silicone and are curved to avoid damaging the paper on the surface of the cigarette 5, thus affecting the combustion performance test.

[0046] In this embodiment, before use, the hole in the center of the second annular ring 34 is normally the smallest hole, which can accommodate fine smoke. When it is a regular cigarette, the hole in the center of the second annular ring 34 is opened, the cigarette 5 is inserted into the center of the second annular ring 34, and then the cigarette is lit.

[0047] To test the specifications of the cigarette, the extension length and speed of the first telescopic motor 12 are set on the first control panel 13. When inhaling, the first telescopic motor 12 drives the first baffle 23 to move towards the first mounting base 11 via the first transmission rod 121. The first baffle 23 drives the arc plate 25 to move on the inner shell 27 via the first locking block 263. The movement of the arc plate 25 drives the first cover plate 283 to detach from the inner shell 27 via the connecting rope 6, gradually opening the through hole of the inner shell 27. At the same time, the second through hole 253 and the third through hole 201 are misaligned to ensure that outside air does not enter the first outer shell 21 through the second through hole 253 and the third through hole 201 when inhaling. The inner shell 27 and the second outer shell 31 together create a negative pressure, allowing the smoke from the cigarette 5 to enter the first outer shell 21. This allows the combustion performance of the cigarette 5 to be tested by different intake volumes and intake speeds. When exhaling, the first telescopic motor 12 drives the first baffle 23 to move away from the first mounting base 11 via the first transmission rod 121, and the arc plate 25 moves towards the rotating column 282. The first cover plate 283 gradually closes the through hole of the inner shell 27 through the sliding of the connecting rope 6. At the same time, the second through hole 253 and the third through hole 201 gradually align, allowing the smoke to be discharged through the first through hole 271, the second through hole 253 and the third through hole 201, facilitating the next intake.

[0048] During inhalation, the extension and retraction speed of the output shaft of the second telescopic motor 47 is simultaneously set on the second control panel 43. The output shaft of the second telescopic motor 47 drives the rack 48 to move up and down in the second slide groove 402, thereby meshing with the first gear 492 and the second gear 494 respectively, and driving the first gear 492 and the second gear 494 to rotate. When the first gear 492 rotates, it drives the first connecting arm 45 to strike the cigarette 5 from above. When the second gear 494 rotates, it bounces the cigarette 5 from the side. The ash of the cigarette 5 is shaken off by the striking and bouncing. Combined with inhalation, the combustion performance of the cigarette 5 is further tested.

[0049] The present invention has provided a detailed description of a cigarette combustion performance testing device. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
