Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a cigarette compression detection device. Background Technology

[0002] Cigarette draw resistance is the resistance encountered when smoking a cigarette. Under certain atmospheric conditions, it is represented by the static pressure difference between the two ends of the cigarette when a certain flow of air passes through it. Draw resistance essentially reflects the smoothness of airflow during the combustion process. Its stability not only affects the overall quality of the cigarette but also directly impacts consumer product acceptance, making it a mandatory inspection item in cigarette quality supervision during production.

[0003] In related technologies, such as Figure 1 As shown, the existing cigarette draw resistance detection device 3000 includes a mounting body 3100 and clamping detection structures 3200 disposed at opposite ends of the mounting body 3100. Each clamping detection structure 3200 includes a rotating drum 3210 and contact heads 3220 disposed on the rotating drum 3210. A cigarette 2000 is disposed between the two opposite contact heads 3220, with both ends of the cigarette 2000 abutting against the contact heads 3220 along the axial direction. Each contact head 3220 is connected to an airflow sensor and an air delivery structure. The airflow sensor detects the airflow intensity to detect the draw resistance of the cigarette 2000. Furthermore, the rotating drum 3210 is rotatably connected to the mounting body 3100 to change the gap between the two opposite contact heads 3220 within the two sets of clamping detection structures 3200, thereby changing the compression of the cigarette 2000 by the two contact heads 3220. This ensures stable clamping of the cigarette 2000 while adapting to different specifications of cigarettes 2000. However, the existing solution cannot directly measure the compression of the cigarette 2000 by the two contact heads 3220, which leads to repeated adjustments during actual operation. The relative position of the rotating drum 3210 and the mounting body 3100 greatly reduces the efficiency of detecting the suction resistance of the cigarette 2000.

[0004] Therefore, there is an urgent need to invent a cigarette compression detection device to solve the above problems. Utility Model Content

[0014] A stop member is threaded into the fixing hole, and the stop member can be fixed to the elastic member along the axial direction relative to the receiving hole.

[0015] As an optional solution, the first measuring bar also includes:

[0016] An abutment is movably disposed within the receiving hole along the axial direction, the diameter of the abutment being adapted to the diameter of the receiving hole, and the abutment being located between the elastic member and the stop member along the axial direction, the abutment being configured to abut against the elastic member and the stop member.

[0017] As an optional solution, the second measuring bar includes:

[0018] The second rod, at least a portion of which can extend into the receiving hole and abut against the elastic element;

[0019] A mating component is fixedly connected to the second rod body, and the mating component has the mating protrusion.

[0020] As an optional solution, the second rod includes:

[0021] A first connecting portion extends along the axial direction;

[0022] The second connecting part extends along the axial direction. The first connecting part and the second connecting part are sequentially connected along the axial direction. The mating member is fixedly connected to the second connecting part. The second connecting part can extend into the receiving hole and abut against the elastic member. The first connecting part is configured to abut against the output end of the cigarette suction resistance detection device. The diameter of the first connecting part and the diameter of the first measuring rod are both the diameter of the cigarette.

[0023] As an optional solution, the second rod body has a weight-reducing hole. The weight-reducing hole extends from the end face of the second connecting part away from the first connecting part along the axial direction. The weight-reducing hole passes through the second connecting part and part of the first connecting part in sequence along the axial direction. Part of the mating part is fixed in the weight-reducing hole.

[0024] As an optional solution, the mating component includes:

[0025] It is fitted into the main body and fixed inside the weight-reducing hole;

[0026] The mating protrusion is fixedly connected to the mating body. The second connecting part is provided with a radially extending clearance hole.

At least a portion of the second measuring rod slides into the receiving hole and abuts against one axial end of the elastic element. The other axial end of the elastic element is fixed relative to the receiving hole by a stop. The ends of the first and second measuring rods, axially away from the second measuring rod and axially away from the first measuring rod, respectively abut against the output end of the cigarette draw resistance detection device. The assembly of the first and second measuring rods in the state where the second measuring rod abuts against the elastic element but the elastic element is not compressed simulates a cigarette, which is then clamped and fixed by the cigarette draw resistance detection device. The axial contraction of the elastic element simulates the compression of the cigarette. A fitting protrusion is provided in the portion of the second measuring rod extending into the receiving hole, and a groove is provided on the outer peripheral wall of the first measuring rod, allowing the fitting protrusion and groove to slide together. This facilitates observation of the compression of the elastic element and improves detection efficiency. Furthermore, by making the end of the elastic element away from the second measuring rod axially adjustable relative to the stop fixed position of the receiving hole, the axial lengths of the first and second measuring rods can be changed when the second measuring rod abuts against the elastic element and the elastic element is not compressed. This simulates cigarettes with different axial lengths, enabling the detection of the compression amount of cigarettes of different lengths and improving applicability. Attached Figure Description

[0043] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] like Figure 1As shown, the existing cigarette draw resistance detection device 3000 includes a mounting body 3100 and clamping detection structures 3200 disposed at opposite ends of the mounting body 3100. Each clamping detection structure 3200 includes a rotating drum 3210 and contact heads 3220 disposed on the rotating drum 3210. A cigarette 2000 is disposed between the two opposite contact heads 3220, with both ends of the cigarette 2000 abutting against the contact heads 3220 along the axial direction. Each contact head 3220 is connected to an airflow sensor and an air delivery structure. The airflow sensor detects the airflow intensity to detect the draw resistance of the cigarette 2000. Furthermore, the rotating drum 3210 is rotatably connected to the mounting body 3100 to change the gap between the two opposite contact heads 3220 within the two sets of clamping detection structures 3200, thereby changing the compression of the cigarette 2000 by the two contact heads 3220. This ensures stable clamping of the cigarette 2000 while adapting to different specifications of cigarettes 2000. However, the existing solution cannot directly measure the compression of the cigarette 2000 by the two contact heads 3220, which leads to repeated adjustments during actual operation. The relative position of the rotating drum 3210 and the mounting body 3100 greatly reduces the efficiency of detecting the suction resistance of the cigarette 2000.

[0047] To solve the above problems, such as Figures 2-6 As shown, this embodiment provides a cigarette compression detection device. The cigarette compression detection device includes a first measuring rod 100 and a second measuring rod 200. The first measuring rod 100 has an axially extending receiving hole 113, within which an axially extendable elastic element 120 is disposed. The second measuring rod 200 at least partially extends into the receiving hole 113 and abuts against one axially extending end of the elastic element 120. The second measuring rod 200 is at least partially slidably engaged with the receiving hole 113. The other axially extending end of the elastic element 120 can be stopped and fixed relative to the receiving hole 113. The position of the other end of the second measuring rod 200 relative to the stop fixed in the receiving hole 113 is adjustable in the axial direction. The end of the second measuring rod 200 away from the first measuring rod 100 and the end of the first measuring rod 100 away from the second measuring rod 200 in the axial direction can respectively abut against the output end of the cigarette suction resistance detection device 3000. The part of the second measuring rod 200 that extends into the receiving hole 113 has a mating protrusion 221. The outer peripheral wall of the first measuring rod 100 is provided with a sliding groove 111 extending in the axial direction. The mating protrusion 221 and the sliding groove 111 slide in fit.

[0048] The cigarette compression detection device has an axially extending receiving hole 113 in the first measuring rod 100, and an axially expandable elastic element 120 in the receiving hole 113. At least a portion of the second measuring rod 200 is slidably engaged with the receiving hole 113, allowing at least a portion of the second measuring rod 200 to extend into the receiving hole 113 and abut against one axial end of the elastic element 120. The other axial end of the elastic element 120 is fixed relative to a stop in the receiving hole 113. This allows the axial ends of the first measuring rod 100 and the second measuring rod 200 to respectively engage with the cigarette draw resistance detection device 30. The output ends of the 00 are connected. The first measuring rod 100 and the second measuring rod 200 are used to assemble a simulated cigarette 2000 in a state where the second measuring rod 200 abuts against the elastic member 120 and the elastic member 120 is not compressed. The cigarette is clamped and fixed by the cigarette draw resistance detection device 3000. The compression of the cigarette 2000 is simulated by the axial contraction of the elastic member 120. By setting a matching protrusion 221 in the part of the second measuring rod 200 that extends into the receiving hole 113, and setting a sliding groove 111 on the outer peripheral wall of the first measuring rod 100, the matching protrusion 221 and the sliding groove 111 are slidably engaged, which can further facilitate the observation of the compression of the elastic member 120 and improve the detection efficiency. Furthermore, by making the end of the elastic member 120 axially away from the second measuring rod 200 axially adjustable relative to the stop fixed position of the receiving hole 113, the axial length of the first measuring rod 100 and the second measuring rod 200 in the state where the second measuring rod 200 abuts against the elastic member 120 and the elastic member 120 is not compressed can be changed to simulate cigarettes 2000 with different axial lengths, realize the detection of the compression amount of cigarettes 2000 with different lengths, and improve applicability.

[0049] It should be noted that in this embodiment, the elastic element 120 is a spring. Springs have a simple structure and are compact, meeting practical installation requirements. In other embodiments, the elastic element 120 may also be a rubber block or other elastic structure; this embodiment does not impose specific limitations.

[0050] Optionally, the outer peripheral wall of the first measuring rod 100 is provided with a scale line 112 extending axially, and the scale line 112 is disposed on at least one side of the slide groove 111 along the axial direction. By providing a scale line 112 extending axially on the outer peripheral wall of the first measuring rod 100 and disposing of the scale line 112 on at least one side of the slide groove 111 along the axial direction, it is easier to determine the sliding distance of the mating protrusion 221 along the slide groove 111, that is, to determine the compression amount of the elastic element 120. It should be noted that in this embodiment, scale lines 112 are provided on both sides of the slide groove 111 along the axial direction to further facilitate observation of the scale. In other embodiments, scale lines 112 may be provided only on one side of the slide groove 111 along the axial direction; this embodiment does not impose a specific limitation.

[0051] As an optional solution, the first measuring rod 100 includes a first rod body 110 and a stop member 130. The first rod body 110 has a receiving hole 113 and a fixing hole 114 connected to the receiving hole 113 in sequence along the axial direction. The inner wall of the fixing hole 114 is provided with an internal thread extending along the axial direction. The stop member 130 is threadedly engaged with the fixing hole 114. The stop member 130 can stop and fix the elastic member 120 relative to the receiving hole 113 in the axial direction. By providing a receiving hole 113 and a fixing hole 114 connected sequentially along the axial direction in the first rod body 110, and providing an internal thread in the inner wall of the fixing hole 114, the fixing hole 114 is sealed by the threaded engagement of the stop member 130 with the fixing hole 114. This not only achieves the axial stopping and fixing of the stop member 130 and the elastic member 120, but also allows for the axial adjustment of the relative position of the stop member 130 with respect to the first rod body 110 through the threaded engagement of the stop member 130 with the fixing hole 114. This changes the position of the elastic member 120 in the receiving hole 113, thereby changing the axial length of the first measuring rod 100 and the second measuring rod 200 in the state where the second measuring rod 200 abuts against the elastic member 120 and the elastic member 120 is not compressed.

[0052] To improve the stopping and fixing effect of the stop member 130 on the elastic member 120, the first measuring rod 100 further includes an abutment member 140. The abutment member 140 is axially movably disposed within the receiving hole 113, and its diameter matches the aperture of the receiving hole 113. The abutment member 140 is axially positioned between the elastic member 120 and the stop member 130, and is configured to abut against both the elastic member 120 and the stop member 130. By movably disposing the abutment member 140, whose diameter matches the aperture of the receiving hole 113, within the receiving hole 113 and positioned between the stop member 130 and the elastic member 120, and by having the abutment member 140 abut against both the stop member 130 and the elastic member 120, the effective contact area can be increased, thereby improving the stopping and fixing effect of the stop member 130 on the elastic member 120.

[0053] In an optional embodiment, the second measuring rod 200 includes a second rod body 210 and a mating member 220, wherein at least a portion of the second rod body 210 can extend into the receiving hole 113 and abut against the elastic member 120, and the mating member 220 is fixedly connected to the second rod body 210, and the mating member 220 has a mating protrusion 221. By disassembling the second measuring rod 200 into the second rod body 210 and the mating member 220, the manufacturing of the second measuring rod 200 can be facilitated.

[0054] Optionally, the second rod 210 includes a first connecting portion 211 and a second connecting portion 212, wherein both the first connecting portion 211 and the second connecting portion 212 extend axially and are sequentially connected axially. The second connecting portion 212 can extend into the receiving hole 113 and abut against the elastic member 120. The mating member 220 is fixedly connected to the second connecting portion 212. The first connecting portion 211 is configured to abut against the output end of the cigarette draw resistance detection device 3000. The diameter of the first connecting portion 211 and the diameter of the first measuring rod 100 are both the diameter of the cigarette 2000. By splitting the second rod 210 into a first connecting part 211 and a second connecting part 212 connected sequentially along the axial direction, the first connecting part 211 abuts against the output end of the cigarette draw resistance detection device 3000, and the second connecting part 212 is fixedly connected to the mating part 220 while abutting against the elastic part 120. It is ensured that the diameter of the first connecting part 211 and the diameter of the first measuring rod 100 are both the diameter of the cigarette 2000. This satisfies the requirement that the second rod 210 extends into the receiving hole 113 along the axial direction, while realistically simulating the effect of the cigarette draw resistance detection device 3000 clamping and fixing the cigarette 2000.

[0055] In this embodiment, the second rod 210 has a weight-reducing hole 213. The weight-reducing hole 213 extends axially from the end face of the second connecting portion 212 away from the first connecting portion 211. The weight-reducing hole 213 passes through the second connecting portion 212 and part of the first connecting portion 211 in sequence along the axial direction. Part of the mating component 220 is fixed in the weight-reducing hole 213. By providing a weight-reducing hole 213 in the second rod 210, the weight-reducing hole 213 buffers the second connecting portion 212 and part of the first connecting portion 211 in sequence along the axial direction. This significantly reduces the weight of the second rod 210 while providing installation space for the mating component 220, thus improving the structural compactness.

[0056] As an optional solution, such as Figure 6 As shown, the mating part 220 includes a mating body 222 and a mating protrusion 221. The mating body 222 is fixed inside the weight-reducing hole 213, and the mating protrusion 221 is fixedly connected to the mating body 222. The second connecting part 212 is provided with a radially extending clearance hole 2121, which communicates with the weight-reducing hole 213. The mating protrusion 221 passes radially through the clearance hole 2121 and slides in engagement with the slide groove 111. By providing a radially extending clearance hole 2121 on the second connecting part 212, when the mating body 222 is fixed inside the weight-reducing hole 213, the mating protrusion 221, which is fixedly connected to the mating body 222, can extend radially out of the clearance hole 2121 and slide in engagement with the slide groove 111.

[0057] In this embodiment, the mating body 222 is capable of radial elastic deformation. When the second connecting part 212 needs to be inserted into the receiving hole 113, the radial elastic deformation of the mating body 222 drives the mating protrusion 221 to retract and avoid the clearance hole 2121, thus preventing interference from the mating protrusion 221 during the insertion of the second connecting part 212 into the receiving hole 113. After the assembly of the second connecting part 212 and the first rod 110 is completed, the mating protrusion 221 is aligned with the slide groove 111, and the mating body 222, under its own elastic force, drives the mating protrusion 221 to extend out of the clearance hole 2121 and be located within the slide groove 111. It should be noted that in this embodiment, the mating body 222 is a U-shaped leaf spring, and the mating protrusion 221 is disposed on the outer wall of the U-shaped leaf spring.

[0058] During the process of the second connecting part 212 extending into the receiving hole 113, the mating protrusion 221 will abut against the inner wall of the receiving hole 113 radially under the drive of the mating body 222. In order to further improve the protection of the mating protrusion 221 and the inner wall of the receiving hole 113, the upper end of the mating protrusion 221 is hemispherical to minimize the friction between the mating protrusion 221 and the receiving hole 113.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
