Description

Technical Field

[0001] The present invention relates to the field of tobacco toxicology research, and in particular to an automatic loading experimental device for heated cigarette cartridges and an animal exposure smoking machine. Background Art

[0002] At present, the consumer demand for heat-not-burn cigarette cartridges is increasing due to their low levels of harmful substances and good smoking taste. The safety of heated cigarette cartridges needs to be further verified in the production process. In the laboratory, a smoking machine is needed to continuously generate aerosols for the next testing stage. In the prior art, the cartridges are manually loaded and the used cartridges are manually removed. Such operations not only reduce the efficiency of the experimental work and affect the speed of the experiment, but also cannot guarantee the continuity of smoking, and cannot achieve automatic and continuous aerosol generation, affecting the experimental results. Therefore, Chinese patent 202110137161.5 discloses an automatic loading experimental device for heated cigarette cartridges and an animal exposure smoking machine. Through the cooperation of a hopper, a loading mechanism, a heating device and a unloading mechanism, uninterrupted loading, heating and unloading processes are achieved to improve the degree of automation. However, the prior art has the following problems when pulling out a cigarette cartridge or a cigarette from a heating device: after the cigarette cartridge is heated and used, the tobacco at the bottom of the cigarette will expand due to the heat, resulting in increased friction between the cigarette and the heating device. Directly removing the cigarette cartridge may easily cause tobacco to remain inside the heating device. If the automatic loading process is continued, subsequent loading will be affected, resulting in the next cigarette cartridge being unable to be correctly inserted into the smoking device, reducing the stability of the automatic loading and unloading mechanism of the cigarette cartridge. Summary of the Invention

[0003] In order to solve one or more technical problems in the prior art, or at least provide a beneficial option, the present invention provides an automatic loading experimental device for heated cigarette cartridges and an animal exposure smoking machine, which solves the problem of tobacco residue after the cigarette is pulled out.

[0012] As an optimal technical solution for an experimental device for automatically filling heated cigarette cartridges, the cartridge clamping member also includes a first clamping jaw and a second clamping jaw arranged opposite to each other, and the first sliding clamping plate and the second sliding clamping plate are respectively slidably arranged on the first clamping jaw and the second clamping jaw toward the clamping surface of the cartridge, and the first sliding clamping plate and the second sliding clamping plate can be driven respectively to slide along the clamping surfaces of the first clamping jaw and the second clamping jaw to drive the cartridge to rotate.

[0013] As an optimal technical solution for an experimental device for automatic loading of heated cigarette cartridges, the first clamping jaw and the second clamping jaw are driven by a first driving member to achieve relative translation to clamp the cartridge; and / or the connecting rod is driven by a second driving member to drive the first sliding clamping plate and the second sliding clamping plate to move along the clamping surfaces of the first clamping jaw and the second clamping jaw.

[0014] As a preferred technical solution for an experimental device for automatically filling heated cigarette cartridges, the first sliding splint and the second sliding splint are respectively provided with anti-slip layers on the surfaces in contact with the cartridges.

[0015] As an optimal technical solution for an experimental device for automatically filling heated cigarette cartridges, the heating device includes a cigarette holder and a heating rod. The cigarette holder is detachably arranged on the heating rod. The cigarette cartridge can be installed in the cigarette holder and driven by the cigarette cartridge clamp to rotate and detach from the cigarette holder.

[0016] As an optimal technical solution for an experimental device for automatically loading heated cigarette cartridges, the heating device also includes a cigarette holder and a cigarette driver. The cigarette holder is used to clamp the cigarette holder, and the cigarette driver can drive the cigarette holder to separate from the heating rod.

[0017] As an optimal technical solution for an experimental device for automatically loading heated cigarette cartridges, the cigarette holder clamp includes a first clamping part and a second clamping part. The first clamping part is used to clamp the cigarette holder, and the second clamping part is used to clamp the cartridge.

[0023] 1. The present application provides a mechanism for rotating and unloading a cigarette cartridge on the unloading mechanism of the automatic loading experimental device for heated cigarette cartridges, thereby quickly and efficiently removing the cigarette cartridge from the heating device. By rotating the cigarette cartridge, the static friction between the cigarette cartridge and the heating device is overcome, and the probability of tobacco residue remaining in the heating device is reduced. The accuracy and continuity of subsequent loading of other cigarette cartridges are also higher, reducing manual intervention, and can ensure the fixed stability between the cigarette cartridge and the heating device after loading. When conducting a smoke exposure experiment, there are fewer factors affecting the smoke concentration, and the collected smoke concentration is more controllable, thereby ensuring the accuracy of the experimental results.

[0025] 3. The present application provides radial clamping force for the cigarette cartridge through the first clamping jaw and the second clamping jaw, which can ensure the stability of the cigarette cartridge clamping and prevent the cigarette cartridge from accidentally falling off. At the same time, it can also ensure that when the first sliding splint and the second sliding splint move, the radial force provided by the first clamping jaw and the second clamping jaw increases the friction between the sliding splint and the cigarette cartridge, ensuring that the cigarette cartridge can be separated from the heating device in a rotational manner and reducing the residual tobacco when the cigarette cartridge is pulled out.

[0026] 4. This application provides an anti-slip layer to ensure that when the cigarette cartridge is pulled out, it is in a rotating state, reducing friction and reducing tobacco residue.

[0027] 5. The present application sets up a cigarette holder installed in the heating rod, and the cigarette cartridge contacts and cooperates with the cigarette holder. When taking out the cigarette cartridge, the cigarette cartridge and the cigarette holder are taken out together, which is efficient and quick. The cigarette cartridge can be rotated relative to the cigarette holder to be quickly taken out. Even if there is some residual tobacco, it will not affect the heating effect of the heating rod part, and the cigarette holder is replaceable, which is lower in cost.

[0028] 6. The present application provides an animal exposure smoking machine with automatic loading and unloading. The loading mechanism obtains the cigarette cartridge, the heating device heats the cigarette cartridge, and the suction device draws it out. The smoke delivery pipe transports the smoke to the animal exposure experiment device.

[0043] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0044] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0045] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0048] In the present invention, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or interactions between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through a transition structure, but are connected solely through a connecting structure to form a single entity. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] In the present invention, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0050] First, the technical concept of the technical solution disclosed by the present invention is explained. Most of the existing cigarette smoking devices have a cigarette holder structure. When the smoking device needs to replace the cigarette cartridge, the usual practice is to take out the cigarette holder together with the cigarette, and then rotate the cigarette cartridge to take the cigarette cartridge out of the cigarette holder. If the cigarette is taken out directly without passing through the cigarette holder, the tobacco will most likely remain in the smoking device. If the cigarette holder is taken out first and then the cigarette is directly pulled out, there will still be tobacco residue in the cigarette holder. After the cigarette is heated and used, the tobacco at the bottom of the cigarette and the bottom of the cigarette holder expand due to heat, and the friction increases. If the cigarette is taken out directly, it is easy to cause tobacco residue. When the cigarette is rotated by hand, the state of adhesion between the cigarette and the bottom of the cigarette holder can be broken, and then the cigarette can be taken out more smoothly without tobacco residue, which is a bad user experience. When this problem occurs on industrial equipment that automatically replaces cigarette cartridges for continuous puffing for experiments, the impact of tobacco residue in the heating device is more obvious. On the one hand, it will affect the efficiency of loading and unloading the cigarette cartridges, and on the other hand, it will lead to inaccurate subsequent experimental results. Therefore, considering that the adhesion between the cigarette cartridge and the cigarette holder can be reduced by rotating the cigarette cartridge, the present application improves the unloading device of the automatic loading experimental device for heated cigarette cartridges, so that the cigarette cartridge and the heating device can be quickly separated, reducing the probability of tobacco residue in the heating device.

[0051] The above is merely an example. In fact, separating the cigarette cartridge and the heating device by rotating the cigarette cartridge to improve the efficiency of loading and unloading the cigarette cartridge is always in line with the technical concept disclosed by the present invention.

[0052] like Figure 1-Figure 5 As shown, an automatic loading experimental device for heating cigarette cartridges 60 disclosed in one embodiment of the present application includes a silo 10, a heating device 20, a loading mechanism 30 and a unloading mechanism 40. The silo 10 can accommodate a plurality of cigarette cartridges 60, and the bottom of the silo 10 has a discharge port to discharge the cigarette cartridges 60 one by one from the bottom. The heating device 20 is used to continuously heat the cigarette cartridge 60 so that the cigarette cartridge 60 generates smoke, and the smoke is collected and utilized for experimental analysis. The loading mechanism 30 is used to insert the cigarette cartridge 60 that has fallen off from the discharge port into the heating device 20. The cigarette cartridge 60 can be fully or partially inserted into the heating device 20 as needed, so as to be able to effectively clamp the cigarette cartridge 60 and ensure effective heating and puffing. When the heating and puffing are completed, the cigarette cartridge 60 is clamped by the unloading mechanism 40 to separate the cigarette cartridge 60 from the heating device 20. Taking into account that in the prior art, when unloading the cigarette cartridge 60, tobacco shreds are easily left by applying force to the cigarette cartridge 60 and directly pulling it out, the unloading mechanism 40 in this embodiment includes a cigarette cartridge 60 clamping piece, which can separate the cigarette cartridge 60 from the heating device 20 with the axis of the cigarette cartridge 60 as the center of rotation. The present embodiment is inspired by the fact that after the user smokes the cigarette cartridge 60, the cigarette cartridge 60 is rotated so as to be taken out. A mechanism that can rotate and unload the cigarette cartridge 60 is provided on the unloading mechanism 40 of the automatic loading experimental device for heating cigarette cartridges 60, so that the cigarette cartridge 60 can be quickly and efficiently taken out of the heating device 20. The expansion effect produced when the heating device 20 heats the cigarette cartridge 60 causes the cigarette cartridge 60 to be difficult to take out and the tobacco shreds to remain easily. This problem can be solved by rotating the cigarette cartridge 60. By rotating the cigarette cartridge 60, the static friction between the cigarette cartridge 60 and the heating device 20 is overcome, and the probability of tobacco shreds remaining in the heating device 20 is smaller. The accuracy and continuity of subsequent loading of other cigarette cartridges 60 are also higher, reducing manual intervention, and ensuring the stability of the cigarette cartridge 60 and the heating device 20 after loading. When conducting a smoke exposure experiment, there are fewer factors affecting the smoke concentration, and the collected smoke concentration is more controllable, thereby ensuring the accuracy of the experimental results.

[0053] like Figure 3-Figure 5As shown, in one embodiment, the cigarette cartridge 60 clamping member includes a first sliding splint 401 and a second sliding splint 402 relatively arranged on the outer periphery of the cigarette cartridge 60, and the first sliding splint 401 and the second sliding splint 402 can move tangentially along the cigarette cartridge 60 to drive the cigarette cartridge 60 to rotate. The first sliding splint 401 and the second sliding splint 402 are plate-like structures arranged opposite to each other. Since the first sliding splint 401 and the second sliding splint 402 are clamped on both sides of the outer periphery of the cigarette cartridge 60, and the axis of the cigarette cartridge 60 and the axis of the heating device 20 are collinear, when the first sliding splint 401 and the second sliding splint 402 move in opposite directions, the cigarette cartridge 60 is driven by the first sliding splint 401 and the second sliding splint 402 to rotate along the axis, thereby overcoming the static friction force increased due to thermal expansion, and quickly separating from the heating device 20 to avoid tobacco residue.

[0054] Those skilled in the art will appreciate that, in addition to the driving by the reverse movement of the first sliding clamp 401 and the second sliding clamp 402 disclosed in this embodiment, the structure for driving the cigarette cartridge 60 to rotate may also be achieved by other clamping methods. For example, in one embodiment, a clamping hoop structure is clamped around the periphery of the cigarette cartridge 60, and the clamping hoop is rotated along the axis of the cigarette cartridge 60 to drive the cigarette cartridge 60 to rotate and quickly separate from the heating device 20 to avoid tobacco residue.

[0055] As an experimental device for automatically loading a heated cigarette cartridge 60 using a first sliding splint 401 and a second sliding splint 402 to drive the cartridge 60 to rotate, in one embodiment, the cartridge 60 clamping member further includes a fixing rod 403 and a connecting rod 404, the fixing rod 403 is arranged between the first sliding splint 401 and the second sliding splint 402, one end of the fixing rod 403 is fixed, and the other end is suspended above the cartridge 60 (such as Figure 3-Figure 5 The embodiment shown) is used to be connected to the connecting rod 404, and the connecting rod 404 includes a first sliding groove 412 and a second sliding groove 413, and a rotating connection part 411 is provided between the first sliding groove 412 and the second sliding groove 413, and the rotating connection part 411 is rotatably connected to the suspended end of the fixed rod 403, and the first sliding splint 401 and the second sliding splint 402 are respectively provided with a sliding pin 405 slidably connected to the first sliding groove 412 and the second sliding groove 413, and one end of the connecting rod 404 can be driven to lift or lower. Since the rotating connection part 411 is rotatably connected to the fixed rod 403, after one end of the connecting rod 404 is lifted, the connecting rod 404 can be rotated around the rotating connection part 411 to drive the first sliding splint 401 and the second sliding splint 402 to move, and since the first sliding splint 401 and the second sliding splint 402 are slidingly arranged, they can move tangentially along the cigarette cartridge 60 respectively under the cooperation of the sliding pin 405 and the sliding groove, thereby driving the cigarette cartridge 60 to rotate.

[0056] Those skilled in the art will appreciate that other drive structures may be used to drive the first sliding clamp 401 and the second sliding clamp 402 to move relative to each other, such as by using an independent air cylinder or hydraulic cylinder to drive, or by using a conventional motor or linear motor to drive, etc. This embodiment does not limit the drive structure of the first sliding clamp 401 and the second sliding clamp 402.

[0057] like Figure 3-Figure 5 As shown, further, in one embodiment, the cigarette cartridge 60 clamping member also includes a first clamping jaw 406 and a second clamping jaw 407 arranged opposite to each other, and the first sliding clamping plate 401 and the second sliding clamping plate 402 are respectively slidably arranged on the first clamping jaw 406 and the second clamping jaw 407 toward the clamping surface of the cigarette cartridge 60, and the first sliding clamping plate 401 and the second sliding clamping plate 402 can be driven respectively to slide along the clamping surfaces of the first clamping jaw 406 and the second clamping jaw 407 to drive the cigarette cartridge 60 to rotate. In this embodiment, the first clamping jaw 406 and the second clamping jaw 407 provide radial clamping force for the cigarette cartridge 60. Since the first sliding clamping plate 401 and the second sliding clamping plate 402 are arranged on the periphery of the cigarette cartridge 60 and can move tangentially along the cigarette cartridge 60 to drive the cigarette cartridge 60 to rotate, when the first clamping jaw 406 and the second clamping jaw 407 clamp the cigarette cartridge 60, the stability of the clamping of the cigarette cartridge 60 can be ensured to prevent the cigarette cartridge 60 from accidentally falling off. At the same time, it can also ensure that when the first sliding clamping plate 401 and the second sliding clamping plate 402 move, the radial force provided by the first clamping jaw 406 and the second clamping jaw 407 increases the friction between the sliding clamp and the cigarette cartridge 60, ensuring that the cigarette cartridge 60 can be separated from the heating device 20 in a rotational manner, and reducing the residual tobacco when the cigarette cartridge 60 is pulled out.

[0058] In one embodiment, the first clamping jaw 406 and the second clamping jaw 407 are driven by a first driving member to achieve relative translation to clamp the cigarette cartridge 60. Specifically, the first driving member can be a first cylinder 408, with both ends of the first cylinder 408 respectively mounted on the first clamping jaw 406 and the second clamping jaw 407. The expansion and contraction of the first cylinder 408 drives the first clamping jaw 406 and / or the second clamping jaw 407 to move relative to each other, thereby applying a radial clamping force to the cigarette cartridge 60 or releasing the clamping force on the cigarette cartridge 60.

[0059] The connecting rod 404 is driven by a second driving member to move the first sliding plate 401 and the second sliding plate 402 along the clamping surfaces of the first clamping jaw 406 and the second clamping jaw 407. Specifically, the second driving member can also be a second cylinder 409, which has one end fixed and the other end pivotally connected to the end of the connecting rod 404. The extension and contraction of the second cylinder 409 drives the end of the connecting rod 404 to rise and fall, and further, through the cooperation of the rotating pin and the sliding slot, drives the first sliding plate 401 and the second sliding plate 402 to rise and fall, thereby driving the cigarette cartridge 60 to rotate and be pulled out of the heating device 20.

[0060] By adopting a cylinder drive method to drive the movement of the first clamping jaw 406, the second clamping jaw 407, and the movement of the first sliding clamping plate 401 and the second sliding clamping plate 402, the transmission is smooth, the inertia is low, the noise is low, and the clamping force of the cigarette cartridge 60 is better controlled, avoiding excessive clamping force affecting the rotation and extraction of the cigarette cartridge 60, thereby ensuring the rapid loading and unloading of the cigarette cartridge 60 in the automatic loading experimental device of the heated cigarette cartridge 60.

[0061] like Figure 3-Figure 5 As shown, in order to prevent the first sliding splint 401 and the second sliding splint 402 from loosening from the surface of the cigarette cartridge 60 and being unable to drive the cigarette cartridge 60 to rotate, in one embodiment, the first sliding splint 401 and the second sliding splint 402 are respectively provided with an anti-skid layer 410 on the surface in contact with the cigarette cartridge 60. In one embodiment, the anti-skid layer 410 can be an anti-skid pattern provided on the surface of the first sliding splint 401 and the second sliding splint 402, or anti-skid sandblasting, which improves the anti-skid effect by increasing the surface roughness of the contact with the cigarette cartridge 60. In another embodiment, the anti-skid layer 410 can be an anti-skid rubber layer provided on the surface of the first sliding splint 401 and the second sliding splint 402. Since the contact between the anti-skid rubber layer and the cigarette cartridge 60 is a flexible contact, it is possible to avoid excessive clamping of the cigarette cartridge 60, resulting in the cigarette cartridge 60 being broken and damaged when the cigarette cartridge 60 is pulled out. This embodiment ensures that when the cigarette cartridge 60 is pulled out, the cigarette cartridge 60 is in a state of rotation and extraction by providing an anti-skid layer 410, thereby reducing friction and reducing tobacco residue.

[0062] like Figure 1-Figure 5As shown, in one embodiment, the heating device 20 includes a cigarette holder 201 and a heating rod 202. The cigarette holder 201 is detachably mounted on the heating rod 202. The cigarette cartridge 60 can be installed in the cigarette holder 201 and driven by the cigarette cartridge 60 clamp to rotate and disengage from the cigarette holder 201. Preferably, the smoking device is used as part of the heating device 20, that is, the cigarette holder 201 and the heating rod 202 form a split smoking device. When the cigarette cartridge 60 is pulled out, the cigarette holder 201 is usually taken out together with the cigarette cartridge 60, and then the cigarette holder 201 and the cigarette cartridge 60 are separated. This can effectively prevent the tobacco from the cigarette cartridge 60 from being left in the smoking device, solving the problem of the tobacco being difficult to clean. The cigarette holder 201 has a through hole running through the front and back, and the cigarette cartridge 60 extends into the through hole. The heating rod 202 is usually a battery, a circuit board, and a heating element assembled together. The heating element is usually cylindrical or sheet-shaped. When smoking, insert the cigarette cartridge 60 into the cigarette holder 201, and the heating element will be inserted into the cigarette cartridge 60. After turning on the switch of the smoking device, the battery supplies power to the heating rod 202 through the circuit board. The heating rod 202 generates heat to bake the cigarette. After the set preheating time, you can smoke. After the preheating time, the heating rod 202 will continue to bake the cigarette. When the smoking is finished, the cigarette cartridge 60 is separated from the heating rod 202 through the cigarette holder 201. At the same time, the clamping force provided by the cigarette holder 201 is relatively moderate and will not break or fold the cigarette cartridge 60. The cigarette holder 201 and the part of the smoking device where the heating rod 202 is installed are magnetically attracted. Of course, plug-in or snap-on methods can also be used to achieve detachable assembly. The present invention is applicable to both commercially available smoking devices and smoking devices developed by the inventor.

[0063] like Figure 1-Figure 5 As shown, in one embodiment, the heating device 20 further includes a cigarette holder 203 and a cigarette driver 204. The cigarette holder 203 is used to hold the cigarette holder 201, and the cigarette driver 204 is capable of driving the cigarette holder 203 to separate from the heating rod 202. The cigarette holder 203 comprises a first clamping portion 205 and a second clamping portion 206. The first clamping portion 205 and the second clamping portion 206 are driven by a first cylinder 408. The first clamping portion 205 is used to clamp the cigarette holder 201, facilitating separation of the cigarette holder 201 from the heating rod 202. The second clamping portion 206 is used to clamp the cigarette cartridge 60. The inner side of the second clamping portion 206 is a circular arc surface, and the clamping force of the second clamping portion 206 is less than the clamping force of the first clamping portion 205, facilitating separation of the cigarette cartridge 60 from the cigarette holder 201.

[0064] like Figure 1-Figure 5In the illustrated embodiment, the loading mechanism 30 is movable between a loading position and a loading position, and the heating device 20 is movable between an initial position, a puffing position, and a discharge position. When the loading mechanism 30 reaches the loading position, the trough on the loading mechanism 30 is aligned with the heating device 20 in the initial position (in combination with the aforementioned embodiment, aligned with the position of the cigarette holder 201), and the cigarette cartridge 60 is pushed into the heating device 20. Subsequently, the loading mechanism 30 returns to the loading position, and the heating device 20 moves from the initial position to the puffing position for puffing. After the puffing is completed, the first clamping portion 205 of the cigarette holder clamping member 203 clamps the cigarette holder 201, the second clamping portion 206 clamps the cigarette cartridge 60, and the heating device 20 returns to the initial position. The first clamping part 205 and the second clamping part 206 move to the unloading position, and at the same time drive the cigarette holder 201 and the cigarette cartridge 60 to separate from the heating rod 202.
