To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0035] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0038] 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.

[0039] like Figure 1As shown, the smoking machine 10 is an array-type multi-channel puff-by-puff smoking machine in the prior art. The smoking machine 10 includes a collector 11 and a cigarette holding cavity 12. The collector 11 has a protrusion 111, and the cigarette holding cavity 12 has a port 121. The protrusion 111 is inserted into the port 121 to connect the collector 11 and the cigarette holding cavity 12. In other words, in the prior art, the collector 11 and the cigarette holding cavity 12 are usually connected by a plug-in method, so that when the cigarette is inserted into the cigarette holding cavity 12, the smoke generated by the cigarette can reach the protrusion 111 through the port 121 to be collected by the collector 11. However, this plug-in connection method means that when using this smoking machine 10 for puff-by-puff analysis, the cigarette holding cavity 12 must first be pulled out relative to the collector 11 before other collectors can be replaced, and the two must be plugged in again before the next puff of smoke can be collected. Obviously, this repeated plugging and unplugging process makes the replacement steps complicated and time-consuming. Furthermore, the frequent physical plugging and unplugging can easily cause gaps between the protrusion 111 and the port 121 due to wear, misalignment, or loose connection, thereby compromising the sealing of the flue gas passage.

[0040] Therefore, refer to Figures 2-6 As shown, this utility model provides a smoking machine 20, which includes a collector 21, a connecting plate 23 and a cigarette holder 22 arranged in sequence.

[0041] The collector 21 has a collection opening 210. The cigarette holder 22 has a first port 221 and a second port 222 at its two ends, respectively, with the first port 221 for inserting the cigarette 220. The connecting plate 23 has a through hole 230.

[0042] The second port 222 abuts against the front side 231 of the connecting plate, and communicates with and is sealed to the through hole 230. The collecting opening 210 abuts against the back side 232 of the connecting plate, or the collecting opening 210 is inserted into the through hole 230 from the back side 232 of the connecting plate, with the inserted end of the collecting opening 210 not extending beyond the front side 231 of the connecting plate. The collecting opening 210 communicates with and is sealed to the through hole 230. The smoke generated by the cigarette stick 220 can reach the collecting opening 210 through the second port 222 and the through hole 230 for collection by the collector 21.

[0043] Specifically, this utility model uses a connecting plate 23, with the collector 21 and the cigarette clamping cavity 22 respectively placed on both sides of the connecting plate 23. The collector 21 can abut against the back 232 of the connecting plate, or the collector 21 and the connecting plate 23 can be connected by plugging, and the embedded end of the collection opening 210 does not exceed the front 231 of the connecting plate. The cigarette clamping cavity 22 abuts against the front 231 of the connecting plate, and the two achieve smoke circulation through the through hole 230 of the connecting plate 23.

[0044] By adopting the above technical solution, the collector 21 and the cigarette clamping cavity 22 can be connected without plugging. Therefore, when replacing the collector 21, there is no need for plugging and unplugging operation. The cigarette clamping cavity 22 can directly maintain abutment with the front side 231 of the connecting plate, that is, the cigarette clamping cavity 22 maintains a sealed connection with the connecting plate 23. The collector 21 can be moved relative to the connecting plate 23 to replace it. This effectively ensures the sealing reliability of the flue gas channel during repeated replacement of the collector 21, prevents flue gas leakage or air mixing, and thus improves the accuracy of the analysis data and the experimental efficiency.

[0045] Further reference Figure 3 As shown, the collection opening 210 includes a protrusion 2102 and an opening 2101. The protrusion 2102 protrudes from the collector 21 toward the connecting plate 23, and the opening 2101 is located at the end of the protrusion 2102 along the protruding direction, that is, the opening 2101 is located at the embedded end of the collection opening 210. The protrusion 2102 is embedded into the through hole 230 from the back side 232 of the connecting plate and does not extend beyond the front side 231 of the connecting plate. The protruding direction is the direction from the collector toward the connecting plate, for example... Figure 2 and Figure 3 The direction z2 is shown.

[0046] In this embodiment, the collector 21 and the connecting plate 23 are connected by a plug-in connection, which enhances the connection strength and sealing between the collector 21 and the connecting plate 23. Furthermore, the protrusion 2102 does not extend beyond the front surface 231 of the connecting plate, avoiding interference with the cigarette clamping cavity 22. In addition, the opening 2101 is positioned at the embedded end of the collection opening 210, ensuring that the smoke from the cigarette clamping cavity 22 reaches the opening 2101 first and then directly enters the collector 21, minimizing the retention and diffusion of smoke in the transmission path, thereby ensuring collection efficiency.

[0047] In some possible embodiments provided by this utility model, reference continues to be made. Figure 3 As shown, a first sealing element 211 is provided between the protrusion 2102 and the through hole 230. The protrusion 2102 and the through hole 230 are sealed together by the first sealing element 211, further ensuring the airtightness of the flue gas passage. For example, the first sealing element 211 is a sealing ring, and the material of the first sealing element 211 is an elastic material such as silicone.

[0048] In some possible embodiments provided by this utility model, a second sealing element 223 is also included. The second port 222 and the through hole 230 are sealed together by the second sealing element 223, further ensuring the airtightness of the flue gas passage. Exemplarily, the second sealing element 223 is a sealing skirt or a sealing cup, which is beneficial for achieving a better seal.

[0049] Furthermore, the second port 222 is provided with a groove, one side of the second seal 223 is embedded in the groove, and the other side of the second seal 223 abuts against the front surface 231 of the connecting plate. That is, the second seal 223 can fit tightly against the front surface 231 of the connecting plate through elastic deformation. This not only achieves a sealed connection between the cigarette clamping cavity 22 and the front surface 231 of the connecting plate, but also provides precise positioning and effective fixation for the second seal 223. This allows the cigarette clamping cavity 22 to move relative to the connecting plate 23 during the replacement of the collector 21, synchronously driving the movement of the second seal 223, which is tightly fitted against the front surface 231 of the connecting plate, further effectively ensuring the sealing performance during repeated replacement of the collector 21.

[0050] In some possible embodiments provided by this utility model, a first displacement component is also included for driving the cigarette holder cavity 22 along a first direction (e.g., Figure 4 and Figure 5 The device moves in the direction shown (y), with the first direction parallel to the connecting plate 23. For example, the first direction is the horizontal direction of the connecting plate 23.

[0051] By moving the cigarette clamping cavity 22 along the first direction, the position of the cigarette clamping cavity 22 is adjusted. On the one hand, this aligns the central axis of the cigarette clamping cavity 22 with the central axis of the through hole 230, meaning that the central axis of the cigarette clamping cavity 22 and the central axis of the through hole 230 are collinear. On the other hand, this allows the cigarette clamping cavity 22 to connect with different collectors 21, thus enabling the replacement of the collectors 21.

[0052] For example, when it is necessary to replace cigarettes 220 or cigarette clamping cavity 22 of different specifications, the dimensions of the different specifications of the components may differ. By driving the cigarette clamping cavity 22 to move along the first direction through the first displacement component, its central axis position can be flexibly adjusted to keep it aligned with the central axis of the fixed through hole 230. This not only improves the assembly tolerance and operability of the smoking machine 20, but also effectively overcomes the poor sealing effect caused by the center offset problem due to the machining tolerance of parts or the initial assembly error.

[0053] For example, there are multiple collectors 21 and multiple through holes 230. The multiple collectors 21 are spaced apart along the first direction, and the multiple through holes 230 are spaced apart along the first direction. The multiple through holes 230 correspond to the multiple collectors 21 respectively. The cigarette holding cavity 22 moves along the first direction, so that the cigarette holding cavity 22 is connected to the corresponding collectors 21 through the multiple through holes 230 respectively, so as to achieve cigarette collection one by one.

[0054] It should be noted that this utility model does not limit the number of cigarette clamping cavities 22; those skilled in the art can select the number according to specific needs. For example, the number of cigarette clamping cavities 22 can be one or more. (Reference) Figures 4-6As shown, when there are multiple cigarette clamping cavities 22, the multiple cigarette clamping cavities 22 can be arranged at intervals along the first direction. The number of through holes 230 is N times the number of cigarette clamping cavities 22, where N is a natural number greater than 1, so as to enable analysis of each cigarette.

[0055] For example, in this embodiment, there is one cigarette clamping cavity 22, multiple collectors 21, and multiple through holes 230. The first puff of smoke from the cigarette 220 is collected by moving the cigarette clamping cavity 22 along a first direction, aligning its central axis with the central axis of the through hole 230. The cigarette clamping cavity 22 then connects to the corresponding first collector 21 through the first through hole 230, thus completing the collection of the first puff of smoke. Next, the cigarette clamping cavity 22 continues to move along the first direction, aligning its central axis with the central axis of the second through hole 230. The cigarette clamping cavity 22 then connects to the corresponding second collector 21 through the second through hole 230, thus completing the collection of the second puff of smoke. This process is repeated to change different smoke channels, i.e., different collectors 21, to complete puff-by-puff collection.

[0056] In one embodiment of this utility model, the smoking machine 20 includes a first slider 233 extending along a first direction, a first displacement component including a first slide rail 241, a cigarette clamping cavity 22 fixedly connected to the first displacement component, and a first slide rail 241 and a first slider 233 slidably connected. The first slide rail 241 can move relative to the first slider 233 along the first direction, thereby driving the cigarette clamping cavity 22 to move along the first direction, so that the central axis of the cigarette clamping cavity 22 is aligned with the central axis of the through hole 230. The sliding cooperation between the first slider 233 and the first slide rail 241 can strictly limit the movement trajectory of the cigarette clamping cavity 22, avoiding deviation, shaking or jamming during adjustment, ensuring that the cigarette clamping cavity 22 always moves smoothly along the preset first direction, thereby ensuring the alignment accuracy of its central axis with the central axis of the through hole 230 of the connecting plate 23, so that it can be installed quickly and accurately.

[0057] Furthermore, in this embodiment, the smoking machine 20 includes a first plate 24, a connecting plate 23, and the first plate 24 are aligned with the self-trapping device in the direction toward the connecting plate (e.g., Figure 2 and Figure 3The components are arranged sequentially in the direction z2 shown. The first slider 233 is located on the connecting plate 23, and the first slide rail 241 is located on the first plate 24. The cigarette clamping cavity 22 passes through the first plate 24 and is fixedly connected to the first plate 24. The first slide rail 241 and the first slider 233 are slidably connected. The first slide rail 241 can move relative to the first slider 233 in a first direction, thereby driving the first plate 24 to move relative to the connecting plate 23 in a first direction, thus synchronously driving the cigarette clamping cavity 22 to move relative to the connecting plate 23 in a first direction, so that the central axis of the cigarette clamping cavity 22 and the central axis of the through hole 230 are aligned in the first direction. The indirect transmission method of "first slide 241 drives first plate 24, first plate 24 drives cigarette clamping cavity 22" can transmit driving force more evenly, avoiding tilting or displacement of cigarette clamping cavity 22 due to uneven local force. At the same time, the setting of first plate 24 can provide auxiliary support for cigarette clamping cavity 22, further restricting its movement trajectory and ensuring that cigarette clamping cavity 22 always moves smoothly along the first direction. This effectively improves the alignment accuracy between its center and the center of through hole 230 of connecting plate 23, which is conducive to improving the reliability of the sealing connection between second port 222 and through hole 230, and preventing smoke leakage due to displacement deviation.

[0058] In another embodiment of this utility model, the smoking machine 20 includes a rack 234 extending along a first direction, a first displacement component including a gear 2621, a cigarette clamping cavity 22 fixedly connected to the first displacement component, and a transmission connection between the gear 2621 and the rack 234. Thus, the gear 2621 can move relative to the rack 234 along the first direction, thereby driving the cigarette clamping cavity 22 to move along the first direction. Through the transmission method of the gear 2621 and the rack 234, the rotational motion of the gear 2621 can be precisely converted into linear displacement, allowing the movement distance of the cigarette clamping cavity 22 to be precisely controlled and quantified, achieving micron-level precision adjustment. Furthermore, the meshing between the gear 2621 and the rack 234 has a self-locking characteristic; once the drive stops, the cigarette clamping cavity 22 can be firmly locked in its current position, preventing accidental displacement due to external vibration or gravity.

[0059] In some possible embodiments provided by this utility model, reference is made to Figure 2 and Figure 4 As shown, the smoking machine 20 includes a first slider 233 extending along a first direction, a first displacement assembly including a first slide rail 241, a cigarette clamping cavity 22 and the first displacement assembly being fixedly connected, the first slide rail 241 and the first slider 233 being slidably connected, and the first slide rail 241 being able to move relative to the first slider 233 along the first direction.

[0060] The smoking machine 20 includes a rack 234 extending along a first direction, a first displacement assembly including a gear 2621, a cigarette clamping cavity 22 fixedly connected to the first displacement assembly, a gear 2621 and a rack 234 being drivenly connected, and a gear 2621 and a first slide rail 241 being fixedly connected. Thus, the gear 2621 can move relative to the rack 234 along the first direction, causing the first slide rail 241 to move relative to the first slider 233 along the first direction, thereby causing the cigarette clamping cavity 22 to move along the first direction.

[0061] Furthermore, the smoking machine 20 also includes a first horizontal plate 26, which is fixedly connected to the first plate 24. A motor 262 is provided on the surface of the first horizontal plate 26 away from the cigarette clamping cavity 22 along the first direction. The motor 262 is provided with a gear 2621. The connecting plate 23 is provided with a rack 234. The gear 2621 and the rack 234 are connected in a transmission manner, so that the first horizontal plate 26 can move relative to the connecting plate 23 along the first direction, thereby driving the first plate 24 to move along the first direction. Simultaneously, the first slide rail 241 can move relative to the first slider 233 along the first direction, thereby simultaneously driving the cigarette clamping cavity 22 to move along the first direction.

[0062] By precisely controlling the motor's speed (e.g., adjusting the pulse signal of a stepper motor), the gear 2621 can rotate slightly, thereby driving the first horizontal plate 26, the first plate 24, the first slide rail 241, and the cigarette clamping cavity 22 to move along the first direction, resulting in faster response and higher position adjustment accuracy. The fixed connection between the first horizontal plate 26 and the first plate 24 forms a rigid linkage frame. The motor 262 is installed at the end of the horizontal plate away from the cigarette clamping cavity 22, which avoids interference with movement in other directions and, through the support of the first horizontal plate 26, ensures that the driving force is evenly transmitted to the first plate 24. Combined with the design of the first slider 233 and the first slide rail 241, this ensures that the cigarette clamping cavity 22 does not tilt or wobble during movement, maintaining a stable trajectory. Furthermore, the meshing transmission between the gear 2621 and the rack 234 has good self-locking properties, firmly locking the position of the cigarette clamping cavity 22 after adjustment, facilitating better installation.

[0063] In some possible embodiments provided by this utility model, a second displacement component is also included, used to drive the cigarette clamping cavity 22 to abut against the front surface 231 of the connecting plate. The second displacement component can drive the cigarette clamping cavity 22 to move in a direction close to the connecting plate 23 and maintain the abutment state, so that the second port 222 of the cigarette clamping cavity 22 is tightly fitted with the front surface 231 of the connecting plate, squeezing the second sealing member 223, compressing it and fully filling it, further optimizing the sealing performance of the smoke passage. Conversely, the second displacement component can drive the cigarette clamping cavity 22 to move in a direction from the self-collector toward the connecting plate, away from the connecting plate 23, for easy disassembly.

[0064] In this invention, after the cigarette clamping cavity 22 is aligned with the through hole 230 via the first displacement component, the second displacement component drives the cigarette clamping cavity 22 to abut against the front surface 231 of the connecting plate, compressing the second sealing element 223 to further ensure sealing and prevent smoke leakage from affecting detection. During subsequent multi-puff smoke collection, the cigarette clamping cavity 22 can always remain abutted against the front surface 231 of the connecting plate; that is, there is no need to operate the second displacement component, as the first displacement component directly drives the cigarette clamping cavity 22 to move along the second direction. This not only enables rapid switching of the collector 21 and puff-by-puff collection but also ensures continuous and stable sealing, significantly improving the efficiency and automation of puff-by-puff analysis.

[0065] Further, refer to Figure 2 , Figure 5 and Figure 6 As shown, the smoking machine includes a second direction (e.g.) Figure 2 , Figure 3 and Figure 6 The second slider 261 extends in the direction z shown. The second displacement assembly includes a second slide rail 271. The cigarette clamping cavity 22 is fixedly connected to the second displacement assembly, and the second slider 261 and the second slide rail 271 are slidably connected. The second slide rail 271 causes the cigarette clamping cavity to abut against the front of the connecting plate, and conversely, the second slide rail 271 can cause the cigarette clamping cavity to move away from the front of the connecting plate. The second direction is perpendicular to the connecting plate 23.

[0066] The second slider 261 provides precise guidance and stable support for the movement of the cigarette clamping cavity 22, ensuring that it maintains a straight trajectory and smooth movement as it approaches or moves away from the connecting plate 23. This allows the cigarette clamping cavity 22 to achieve precise and controllable pressing contact or separation with the connecting plate 23, thereby quickly establishing a reliable sealing connection when needed, or easily disengaging during equipment maintenance, greatly improving the convenience of equipment operation, the reliability of the sealing connection, and the overall work efficiency.

[0067] Furthermore, the smoking machine 20 also includes a second plate 25 and a second horizontal plate 27, the second plate 25 and the first plate 24 being aligned in the direction from the cigarette holder cavity toward the connecting plate (e.g. Figure 2 and Figure 3 The plates are arranged sequentially in the direction z1 shown, i.e., in the second direction, the first plate 24 is located between the connecting plate 23 and the second plate 25. The cigarette holder cavity 22 passes through the second plate 25 and the first plate 24 sequentially and is fixedly connected to them respectively. The second horizontal plate 27 and the first horizontal plate 26 are arranged along a third direction (e.g., in the direction z1 shown). Figures 2-6The components are arranged sequentially in the direction x shown. The second horizontal plate 27 and the second plate 25 are fixedly connected. The first horizontal plate 26 is provided with a second slider 261, and the second horizontal plate 27 is provided with a second slide rail 271. The second slider 261 and the second slide rail 271 are slidably connected, allowing the second horizontal plate 27 to move along the second direction, thereby driving the second plate 25 to move along the second direction, which in turn drives the cigarette clamping cavity 22 to move along the second direction. Specifically, the cigarette clamping cavity 22 is driven to move from the cigarette clamping cavity toward the connecting plate, causing the cigarette clamping cavity 22 to abut against the front surface 231 of the connecting plate, further causing the second seal 223 to abut against the front surface 231 of the connecting plate (i.e., compressing the second seal 223). Conversely, the second slide rail 271 can drive the cigarette clamping cavity 22 to move from the collector toward the connecting plate, i.e., the cigarette clamping cavity 22 moves away from the front surface 231 of the connecting plate, causing the second seal 223 to separate from the front surface 231 of the connecting plate (i.e., releasing the second seal 223). For example, the third direction is the vertical direction of the connecting plate 23.

[0068] By adopting the above technical solution, and by setting up the second plate 25 and the second horizontal plate 27, which together with the first plate 24, the first horizontal plate 26, and other components to form a linkage structure, the precise and stable linear movement of the cigarette clamping cavity 22 along the third direction is achieved. The sliding cooperation between the second slide rail 271 and the second slider 261 accurately transmits the movement of the second horizontal plate 27 to the second plate 25 and the cigarette clamping cavity 22, allowing it to smoothly approach or move away from the connecting plate 23 along the second direction.

[0069] In this embodiment, reference Figure 6 As shown, the smoking machine 20 also includes a cylinder 272, which is located on the first horizontal plate 26. The cylinder 272 is used to drive the second horizontal plate 27 to move in the second direction, thereby driving the second plate 25 to move in the second direction, which in turn drives the cigarette clamping cavity 22 to move in the second direction, thus realizing the automation and precise control of the movement of the cigarette clamping cavity 22 in the second direction.

[0070] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. 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.
