Description

Technical Field

[0001] This utility model relates to the field of tobacco research and evaluation, specifically to a cigarette smoking simulation device with loaded materials. Background Technology

[0002] Cigarette smoking simulation devices are important tools for studying cigarette combustion, smoke component release, and assessing the hazards of cigarettes. As research into the hazards of cigarettes deepens and the demand for technologies such as harm reduction and tar reduction increases, the technology of smoking simulation devices is also constantly evolving.

[0003] Most existing simulated smoking devices use a fixed amount of smoke, which cannot be flexibly adjusted to suit the habits of different smokers. For example, the amount of smoke per puff, the duration of each puff, and the interval between puffs vary considerably among actual smokers, while the adjustable range of the existing devices is not flexible enough to accurately simulate real smoking behavior. In addition, devices with fixed amounts of smoke cannot meet the different smoke volume requirements of different types of cigarettes.

[0004] In real smoking, smokers take intermittent puffs and flick ash, which existing devices struggle to simulate.

[0005] The existing device does not have a structure that can easily load adsorbent materials or other slow-release particles. This means that when testing the effect of tar-reducing particles, a cigarette with an empty tube section must be used. Moreover, the original fiber bundle must be removed before loading the material and then the fiber bundle must be put back. This can easily cause changes to the structure of the filter rod fiber bundle, making it difficult to ensure the accuracy of the experiment.

[0006] The existing equipment lacks flexibility, problems during testing cannot be detected in a timely manner, and the number of cigarettes measured cannot be easily changed. If any abnormality is found during the experiment, the entire experiment must be stopped for inspection. Summary of the Invention

[0007] This invention addresses the limitations of current devices for simulating smoking behavior, such as the inability to simulate the discontinuous smoking process and insufficient reliability of experimental results. It provides a cigarette smoking simulation device with added materials. This device can not only simulate real smoking but also add materials (such as adsorbent materials, fragrance materials, etc.) to remove some harmful substances from cigarettes or improve the smoking taste.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cigarette smoking simulation device with loading material, comprising a peristaltic pump, a buffer tank, a first pressure gauge, a first valve, an anti-backflow structure, a collection bottle, a total flow meter, a Cambridge filter holder, a vacuum gauge, and multiple cigarette holders connected in series via pipelines. The multiple cigarette holders are connected in parallel and then connected to the vacuum gauge via pipelines. Each cigarette holder includes a connecting pipe, on which a third valve and a branch flow meter are installed, and a glass tube is connected to the end of the connecting pipe. A Cambridge filter is provided inside the Cambridge filter holder. A branch pipe connects the pipeline between the first valve and the anti-backflow structure, and a second pressure gauge and a second valve are installed on the branch pipe. The first pressure gauge, the second pressure gauge, the total flow meter, and the multiple parallel branch flow meters are all connected to a main display.

[0009] Furthermore, the anti-backflow structure is a variable-diameter pipe structure with a diameter larger than that of the connecting pipe, and the shape of the anti-backflow structure is spherical or inverted hourglass.

[0010] Furthermore, the number of anti-backflow structures is at least one, and each anti-backflow structure has the same diameter or different diameters.

[0011] Furthermore, the collection bottle includes a bottle body and a bottle cap. The bottle body is made of transparent material, and the bottle body and the bottle cap are sealed together by a sealing ring. Both the air inlet pipe and the air outlet pipe are introduced into the collection bottle from the top of the bottle body.

[0012] Furthermore, the outlet of the air inlet pipe located at the collection bottle is introduced into the collection bottle and is located at the bottom of the collection bottle, the inlet of the air outlet pipe of the collection bottle is located at the top of the collection bottle, and the outlet of the air outlet pipe is connected to the anti-backflow structure.

[0013] Furthermore, a tray is provided below the plurality of cigarette holders, a support frame is installed on the tray, and a spray pipe is installed on the top of the support frame above the cigarette holders. The spray pipe is connected to a water supply pipe, and a water valve is installed on the water supply pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the pipeline of the smoking simulation device, a peristaltic pump is used to achieve smoking and flow control, realize the control of smoke flow and the start and end of smoking, and simulate the real smoking state.

[0016] 2. Design a complete suction device consisting of a Cambridge filter, cigarette holder, loading material, collection bottle, air inlet pipe, air outlet pipe and negative pressure suction unit to facilitate the process of testing the performance of the loading material.

[0017] 3. The loading material glass tube can be loaded with adsorbent materials that adsorb harmful substances, or with materials that enhance the taste of cigarettes.

[0018] 4. An anti-backflow structure is installed to prevent the collected solution from overflowing and entering the peristaltic pump when the instantaneous flow rate is too high, which could damage the instrument.

[0019] 5. The cigarette smoking simulation device with loading material of this utility model has a simple structure and is easy to use.

[0020] 6. This utility model is equipped with a main display, which allows for clear and convenient viewing of the real-time status of different pipeline locations.

[0021] 7. This utility model is equipped with a spray device to extinguish cigarette butts, so as to ensure the safety of experimental personnel and the environment.

[0022] 8. Each branch of this device can be controlled independently, and can be easily added or removed. Furthermore, if a problem occurs during the experiment, the experiment of a certain branch can be stopped without stopping the entire experiment. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to specific embodiments. Example 1

The multiple cigarette holders 12 are connected in parallel to the vacuum gauge 18 via pipelines. Each cigarette holder 12 includes a connecting pipe, on which a third valve 13 and a branch flow meter 14 are installed, and a glass tube 15 is connected to the end of the connecting pipe. The Cambridge filter holder 11 contains a Cambridge filter 10. The pipeline between the first valve 4 and the anti-backflow structure 7 is connected to a branch pipe, on which a second pressure gauge 6 and a second valve 5 are installed. The first pressure gauge 3, the second pressure gauge 6, the total flow meter 9, and the multiple parallel branch flow meters 14 are electrically connected to a main display 17.

[0028] The peristaltic pump 1 is used to provide negative pressure for the smoking simulation device, control the inhalation and cessation of smoking, and control the inhalation volume by adjusting the rotation speed.

[0029] The buffer tank 2 is used to reduce drastic fluctuations in airflow.

[0030] The pressure gauge is used to check the negative pressure of the gas.

[0031] The first valve 4 is used to control the emergency shutdown of the entire device.

[0032] The second valve 5 is a vent valve, which can be used as an emergency valve to stop the diffusion of smoke, or it can be used to introduce the atmosphere during the suction interval to simulate the smoking process.

[0033] The third valve 13 is used to control the start or end of the smoking process of a single cigarette.

[0034] Furthermore, the anti-backflow structure 7 is a variable diameter pipe structure with a diameter larger than that of the connecting pipe, and the shape of the anti-backflow structure 7 is spherical or inverted hourglass.

[0035] Furthermore, the number of anti-backflow structures 7 is at least one, and each anti-backflow structure has the same diameter or different diameters.

[0036] Furthermore, the collection bottle 8 includes a bottle body and a bottle cap. The bottle body is made of transparent material, and the bottle body and the bottle cap are sealed together by a sealing ring. The air inlet pipe and the air outlet pipe are both introduced into the collection bottle 8 from the upper part of the bottle body.

[0037] Furthermore, the outlet of the air inlet pipe located at the collection bottle 8 is introduced into the collection bottle 8 and is located at the bottom of the collection bottle 8, the inlet of the air outlet pipe of the collection bottle 8 is located at the top of the collection bottle 8, and the outlet of the air outlet pipe is connected to the anti-backflow structure 7.

[0038] Furthermore, a tray 19 is provided below each of the multiple cigarette holders 12, a support frame is installed on the tray 19, and a spray pipe 21 located above the cigarette holders 12 is installed on the top of the support frame. The spray pipe 21 is connected to a water supply pipe, which is connected to a water source, and a water valve 20 is installed on the water supply pipe.

[0039] The cigarette holder 12 is used to hold the cigarette filter rod 16, which is connected through the glass tube 15.

[0040] The branch flow meter 14 is used to observe the gas flow rate of a single cigarette and to check for leaks.

[0041] The vacuum gauge 18 is used to observe the vacuum level and monitor the negative pressure within the system.

[0042] The main display 17 is a main display for pressure gauges and flow meters.

[0043] The Cambridge filter 10 is used for flue gas capture.

[0044] The glass tube 15 is loaded with materials that adsorb target substances or improve the taste of cigarettes.

[0045] The spray pipe 21 is extinguished at the end of the experiment to ensure safety.

[0046] The water valve 20 can adjust the amount of water sprayed.

[0047] The tray 19 can catch the soot and water generated during the experiment, ensuring a safe and clean experimental environment.

[0048] Work process:

[0049] Connect the cigarette filter rod to the glass tube 15. If the cigarette has an empty tube section, it can be directly inserted into the inhalation position. If the cigarette does not have an empty tube section, the filter rod can be cut in the middle, and then the two sections of the filter rod can be connected with the glass tube 15. The glass tube 15 can be filled with the required adsorbent or materials loaded with other functional substances. Then, turn on the peristaltic pump 1, the first valve 4, and the third valve 13 to start the cigarette smoking process. The suction volume is controlled by adjusting the speed of the peristaltic pump 1. The smoke is captured by the Cambridge filter 10. The uncaptured smoke enters the collection bottle 8 (the collection bottle 8 contains absorbent liquid to prevent residual extracted substances from entering the pump and the atmosphere and causing pollution). During the smoking process, the pressure and flow of each pressure gauge and flow meter can be monitored and displayed in real time through the main display 17, and leaks can be checked. In case of special circumstances, open the second valve 5, which acts as a vent valve, to release the pressure in the device and prevent accidents. Alternatively, the first valve 4 can be closed to stop the diffusion of smoke. Meanwhile, the vent valve 5 can also be used to intermittently vent to the atmosphere to simulate the actual pauses in smoking. The frequency and duration of these pauses can be easily controlled by the valve. After smoking, the second valve 5 is opened first to restore the system to atmospheric pressure, and then the peristaltic pump 1, the first valve 4, and the third valve 13 are closed. Then, the water valve 20 is opened to spray water from the spray pipe 21 to extinguish any remaining cigarette butts. Subsequently, the quality of the cigarette is evaluated by analyzing the smoke components captured by the Cambridge filter 10. Materials (such as adsorbent materials, flavoring materials, etc.) can be loaded onto the glass tube 15 to remove some harmful substances from the cigarette or improve the smoking experience.
