Description

Technical Field

[0001] This utility model belongs to the field of cigarette and electronic cigarette smoking simulation technology, and specifically relates to a modular cigarette and electronic cigarette smoking device. Background Technology

[0002] Globally, cigarettes and e-cigarettes occupy a large market share. Both cigarettes and e-cigarettes contain various harmful substances to varying degrees. Therefore, smoking cigarettes or e-cigarettes will cause varying degrees of inhalation toxicity to the human body. Research on the inhalation toxicity of cigarettes and e-cigarettes has always been a key topic.

[0003] In studies on the inhalation toxicity of cigarettes and e-cigarettes, smoking machines are a commonly used device. These machines simulate human inhalation flow rate characteristics according to relevant GB or ISO standards to generate smoke, and then the inhalation toxicity or smoke composition of the generated smoke is studied. Currently, most smoking machines comply with GB / T 16450-2004, but they have not made innovative breakthroughs based on the national standard, thus exhibiting the following limitations: Limitation 1: Fixed smoking channels. These smoking machines typically have a fixed number of smoking channels, resulting in a single type of channel and requiring multiple smoking machines of different models to handle different experimental scales. Limitation 2: The smoking method of mainstream smoking machines is singular, usually using a linkage mechanism to drive a piston for smoking, which is too simplistic in meeting the need for standard inhalation flow rates for simulating cigarettes and e-cigarettes. Limitation 3: The smoking capacity of mainstream smoking machines is relatively fixed. The smoking tank is usually of a fixed size, and the smoking capacity is limited by the size, failing to comprehensively meet the diverse needs of experiments.

Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0032] Example 1:

[0033] like Figure 1-8 As shown, a modular cigarette and electronic cigarette smoking device consists of several smoking units. Each smoking unit includes a smoking module 1, a smoking cylinder 2, a reversing valve assembly 3, and a housing 4. The smoking module 1 includes a linear drive mechanism 11 disposed within the housing, and a sliding mechanism 12 is provided on the linear drive mechanism 11 and extends to the outside of the housing 4. The smoking cylinder 2 is detachably disposed on the housing 4 and includes a cylinder body 21 and a piston mechanism 22. The sliding mechanism 12 is connected to the piston mechanism 22 and is used to drive the piston mechanism 22 to move linearly. The reversing valve assembly 3 is disposed on the housing 4 and is used to connect with the cylinder body 21 to realize the intake and exhaust of air into the cylinder body 21.

[0034] In this embodiment, as a specific solution, the outer shell 4 is provided with a fixing plate 41, and the cylinder 21 is mounted on the outer shell 4 through the fixing plate 41.

[0035] In this embodiment, as a specific solution, the cylinder body 21 includes a glass cylinder 211, a front sealing plate 212 and a rear sealing plate 213 disposed at both ends of the glass cylinder 211. The front sealing plate 212 is provided with a pair of connectors 214 communicating with the inside of the cylinder body 21. The connectors 214 are used to connect with the reversing valve assembly 3 to realize air inlet and outlet. The rear sealing plate 213 is provided with a fixing nut 215, which is used to fix the cylinder body 21 to the fixing plate 41.

[0036] In this embodiment, as a more specific solution, the U-shaped slot 411 on the fixing plate 41 is used to lock the cylinder 21 onto the outer shell 4. When the cylinder 21 is placed onto the outer shell 4, the fixing nut 215 is locked onto the U-shaped slot 411. Then, the fixing nut 215 is turned to adjust the distance between the fixing nut 215 and the rear sealing plate 213, so that the fixing plate 41 locks the cylinder 21 between the rear sealing plate 213 and the end of the fixing nut 215.

[0037] In this embodiment, as a specific solution, the piston mechanism 22 includes a piston 221 disposed in the cylinder 21 and a piston rod 222 connected to the piston 221. The piston rod 222 extends outside the cylinder 21, and the end of the piston rod 222 is provided with an adjusting nut 223 and a fixing screw 224. The adjusting nut 223 and the fixing screw 224 are used to connect the piston rod 222 to the sliding mechanism 12.

[0038] In this embodiment, as a more specific solution, the adjusting nut 223 is screwed onto the end of the piston rod 222, and the fixing screw 224 passes through the sliding mechanism 12 and is screwed onto the end of the piston rod 222, so that the sliding mechanism 12 is locked between the adjusting nut 223 and the fixing screw 224. When disassembling the cylinder body 21, the fixing screw 224 is removed and the fixing nut 215 is loosened.

[0039] In this embodiment, as a specific solution, the sliding mechanism 12 includes a frame 121 connected to the linear drive mechanism 11. The frame 121 is provided with a slide rail 122. The slide rail 122 is provided with a slider 123 and the slider 123 is connected to the linear drive mechanism 11. The slider 123 is provided with a push-pull block 124 and the push-pull block 124 is connected to the piston rod 222 of the piston mechanism.

[0040] In this embodiment, as a more specific solution, the linear drive mechanism 11 adopts a lead screw motor, and the frame 121 is fixed inside the outer shell 4. The lead screw of the lead screw motor passes through the slider 123. When the lead screw rotates, it pushes the slider 123 to move on the slide rail 122. More specifically, the frame 121 is also provided with a limit switch 125. The limit switch 125 is connected to the outside of the outer shell 4 through a cable to control the stroke of the lead screw motor.

[0041] In this embodiment, as a specific solution, the outer shell 4 is provided with a sliding groove 42, and the push-pull block 124 slides in the sliding groove 42, which can limit the range of motion of the push-pull block 124 to a certain extent.

[0042] In this embodiment, as a specific solution, a sealing ring 5 is also provided between the piston 221 and the cylinder 21.

[0043] In this embodiment, as a specific solution, the smoking unit is connected to the outer casing 4 via a connecting plate 6. The installation design of the connecting plate allows for the free combination of multiple smoking units, enabling diverse experimental needs to be met with a single device.

[0044] In this embodiment, as a specific solution, the outer shell 4 is provided with a positioning pin 43 and a clamping seat 44, and the connecting plate 6 is provided with a positioning hole 61 and a clamping device 62. The positioning hole 61 on the connecting plate 6 is engaged with the positioning pin 43, and the clamping device 62 is engaged with the clamping seat 44 to realize the connection between the two smoking units.

[0045] In this embodiment, as a specific solution, the reversing valve assembly 3 includes two clamp valves 31, which are detachably mounted on the housing 4. The clamp valves 31 are used to connect the cylinder body and the smoking filter and experimental instruments via hoses. The two clamp valves 31 can control the smoking and smoke output of the cylinder body 21 respectively, preventing smoke from cigarettes and e-cigarettes from contaminating the valve body, and also facilitating hose disassembly and maintenance.

[0046] The working principle of this utility model is as follows:

[0047] During operation, select a smoke cylinder 2 of appropriate specifications, and tighten the fixing nut 215 on the fixing plate 41 of the outer shell 4 to lock the smoke cylinder 2 into the U-shaped groove 411 of the fixing plate 41; then adjust the piston 221 until it is in contact with the front sealing plate 212 to achieve zeroing, and tighten the fixing screw 224 to fix the piston rod 222 to the push-pull block 124;

[0048] A silicone tube connects the smoking filter, one of the clamp valves 31 of the reversing valve group 3, and one of the connectors 214 on the cylinder 21. Another silicone tube connects the experimental instrument, another clamp valve 31 of the reversing valve group 3, and another connector 214 on the cylinder 21. The linear drive mechanism 11 provides power to cause the push-pull block 124 to push the piston rod 222 to move, thereby simulating the smoking and smoke emission actions through the cylinder 21. The experimental instrument then analyzes the smoke.

[0049] When modular combination is required, multiple smoking units are placed side by side, multiple smoking units are connected by a connecting plate, and then the aviation plug 45 (the aviation plug is electrically connected to the linear drive mechanism 11) is connected in series by a connecting cable. Then, a separate control line is connected to the host for modular control. When using modularly, smoking cylinders 2 of different sizes can be installed, or smoking curves with different parameters can be set for comparison or incremental / decrease experiments.

[0050] This device is mainly used to simulate the smoke produced by human smoking cigarettes and e-cigarettes, and to analyze the smoke. It uses a lead screw motor to drive the smoking cylinder to draw out smoke, and can design different smoking curves according to different experimental needs. It can also produce a large amount of smoke through rapid continuous smoking to meet the modeling needs of animal smoking models.

[0051] This invention adopts a modular design, allowing for the flexible combination of several smoking units connected in series via a connecting plate for batch experiments. Each smoking module can be configured with smoking tanks of different capacities, enabling the fulfillment of various experimental needs through a single main smoking experimental device. The smoking tanks are replaceable, allowing for the replacement with smoking tanks of different capacities to meet diverse experimental requirements. Furthermore, the linear drive mechanism controls the smoking tanks to simulate smoking, and the smoking action parameters can be adjusted according to actual experimental needs to satisfy various experimental requirements.

[0052] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
