Description

Technical Field

[0001] This utility model relates to the field of novel tobacco detection technology, and in particular to an oil filtration device and a smoking machine system. Background Technology

[0002] Electronic cigarettes are a new type of tobacco product. Since there is no combustion process during operation, electronic cigarettes effectively avoid the generation of harmful substances caused by high-temperature combustion, making them relatively healthier and more environmentally friendly compared to traditional cigarettes.

[0003] Currently, e-cigarette testing still utilizes traditional cigarette-style smoking machines, primarily consisting of a cigarette holder, Cambridge filters, a drive unit, and a conduit. However, during e-cigarette use, some products, due to flawed design or low atomization efficiency, allow e-liquid to enter the machine along with the inhalation airflow, causing equipment malfunction. While the Cambridge filters in these machines can block some tar produced by traditional cigarettes, their main function is to capture nicotine and other chemical substances in the smoke for analysis and testing, not to filter e-liquid. Therefore, during e-cigarette testing or extended inhalation experiments, most e-liquid still enters the drive unit through the gas flow channel. Furthermore, e-liquid typically has high viscosity, affecting the reliability of the drive unit. On the other hand, smoking machines usually have a fixed inhalation curve. The general control principle involves changing the internal and external pressure difference through the reciprocating motion of the drive unit to achieve a specified inhalation volume. However, when e-liquid enters the drive unit, the significant difference between liquid and gas densities can cause a deviation in the actual inhalation volume, affecting the accuracy of related tests.

[0004] Therefore, designing a device to prevent e-liquid from entering the drive mechanism is of great significance for the reliable operation of the smoking machine and for improving the accuracy of related tests. Utility Model Content

[0005] The purpose of this invention is to provide an oil filtration device and a smoke extraction machine system, so as to reduce the amount of oil entering the drive device and improve the reliability of the piston mechanism and the accuracy of the suction capacity.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An oil filtration device for use in a smoke extraction machine system includes an inlet channel, an outlet channel, and an oil-gas separation mechanism. Under the action of the smoke extraction machine system, the smoke can enter the oil-gas separation mechanism through the inlet channel and flow along a wave-shaped path in the oil-gas separation mechanism to the outlet channel.

[0008] Furthermore, the oil-gas separation mechanism includes a first baffle and a second baffle. The first baffle and the housing of the oil filter device form a first oil-gas separation port for the flow of flue gas. The second baffle and the housing of the oil filter device form a second oil-gas separation port for the flow of flue gas. The first oil-gas separation port is located near the inlet channel, and the second oil-gas separation port is located away from the inlet channel. This allows the flue gas to enter the oil-gas separation mechanism and then pass through the first and second baffles along a wave-like path within the oil filter device to reach the outlet channel.

[0009] Furthermore, the first baffle is provided with an oil leakage hole at the far end of the inlet channel, which can collect the e-liquid separated from the smoke.

[0010] Furthermore, the oil filtration device has an oil drain port on the opposite side of the inlet channel, so that the e-liquid collected through the oil drain hole can be concentrated at the oil drain port.

[0011] Furthermore, the oil filtration device includes an oil drain plate, at least a portion of which has a height difference to guide the e-liquid to concentrate at the oil drain port, which is located at the lowest end of the oil drain plate.

[0012] Furthermore, at least one of the entrance passage and the exit passage includes a corner and / or an inclined baffle.

[0013] Furthermore, the angle between the inclined baffle in the inlet channel and the flow direction of the smoke is less than 90°, so as to guide the e-liquid separated from the smoke into the oil-gas separation mechanism, and / or, the angle between the inclined baffle in the outlet channel and the flow direction of the smoke is less than 90°, so as to prevent the e-liquid separated from the smoke from flowing out of the oil-gas separation mechanism.

[0014] Furthermore, the inlet channel includes an inlet, the outlet channel includes an outlet, and the flue gas flows successively through the inlet, the corner section, the inclined baffle and the oil-gas separation mechanism in the inlet channel, and / or, the flue gas flows successively through the oil-gas separation mechanism, the inclined baffle, the corner section and the outlet in the outlet channel.

[0015] Furthermore, the housing structure of the oil filtration device is made of transparent plexiglass.

[0016] This utility model further claims a smoking machine system that can be used for electronic cigarette smoking test detection. The smoking machine system includes an electronic cigarette holding device and a driving device. The smoking machine system constructs an airflow channel between the electronic cigarette holding device and the driving device. The smoking machine system also includes an oil filter device, which is disposed in the airflow channel. The oil filter device includes an inlet channel, an outlet channel, and an oil-gas separation mechanism. Under the action of the smoking machine system, the smoke can pass through the inlet channel, the oil-gas separation mechanism, and the outlet channel successively. The oil-gas separation mechanism can separate the e-liquid in the smoke.

[0017] Furthermore, the oil filtration device is an oil filtration device according to any of the above-mentioned technical solutions.

[0018] Furthermore, the smoking machine system also includes a filter mounting section, which is located between the oil filtration device and the electronic cigarette holding device; the drive device includes a piston mechanism and a motor, with the motor providing power to the piston mechanism; the oil filtration device is connected to the piston mechanism through an airflow channel, and the components of the smoke after entering the oil filtration device and separating the e-liquid flow out through the piston mechanism; the airflow channel includes an inhalation conduit, a filter conduit, and an exhaust conduit; the two ends of the inhalation conduit are respectively connected to the electronic cigarette holding device and the filter mounting section; the two ends of the filter conduit are respectively connected to the oil filtration device and the piston mechanism; the components of the smoke after entering the oil filtration device and separating the e-liquid flow out through the exhaust conduit via the piston mechanism.

[0019] This utility model provides an oil filtration device and a smoke extraction machine system. By setting up an oil filtration device to separate the grease in the smoke, the amount of grease entering the drive device during the extraction test is reduced, thereby improving the reliability of the drive device and extending its service life. Secondly, reducing the amount of grease entering the drive device ensures that the set extraction capacity of the smoke extraction machine system does not deviate, thereby improving the accuracy of related tests.

Based on the specification, claims and drawings disclosed in this specification, those skilled in the art can easily understand the related objectives and advantages of this utility model.

[0058] 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.

[0059] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0060] 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.

[0061] like Figure 1 As shown, a traditional smoking machine system consists of an electronic cigarette 100, an electronic cigarette holding device 200, a filter mounting part 300, a piston mechanism 400, a motor 500, an inhalation conduit 610, a filter conduit 620, and an exhaust conduit 630. During a smoking test, the motor 500 controls the piston mechanism 400 to reciprocate, changing the internal and external pressure difference to achieve the specified smoke extraction capacity, thereby enabling the testing of the physical and chemical properties of the electronic cigarette 100.

[0062] like Figure 2-6 The present invention is shown in one embodiment. A smoking machine system for testing the inhalation of an electronic cigarette 100 is provided. The smoking machine system includes an electronic cigarette holding device 200 and a driving device. An airflow channel is constructed between the electronic cigarette holding device 200 and the driving device. An oil filter device 700 is provided in the airflow channel to prevent e-liquid in the electronic cigarette 100 from entering the driving device through the airflow channel.

[0063] Furthermore, such as Figures 2-3As shown, the oil filtration device 700 includes an inlet channel, an oil-gas separation mechanism, and an outlet channel. The smoke generated by the electronic cigarette, under the action of the smoking machine system, enters the oil-gas separation mechanism through the inlet channel and flows from the oil-gas separation mechanism to the outlet channel, thereby separating the e-liquid from the smoke. Preferably, the smoke flows along a wave-like path in the oil-gas separation mechanism to the outlet channel. After the smoking test begins, the electronic cigarette is heated under the action of the driving device to generate the smoke to be tested. At this time, the smoke contains a large amount of e-liquid components, which then enter the oil-gas separation mechanism through the inlet channel to separate the e-liquid. The remaining components after the e-liquid separation flow out from the outlet channel and enter the driving device through the airflow channel. Furthermore, the housing structure of the oil filtration device 700 is made of transparent plexiglass, and the housing structure may further include an outer shell 740, allowing the user to directly observe the oil filtration situation inside the oil filtration device 700 from the outside.

[0064] Furthermore, the filter mounting section 300 is located between the oil filtration device 700 and the electronic cigarette holding device 200. The filter mounting section 300 is typically used to mount Cambridge filters that capture nicotine and other chemicals in the smoke. Further, the drive device includes a piston mechanism 400 and a motor 500. The motor 500 is electrically connected to the piston mechanism 400 to provide power, so that the piston mechanism 400 can reciprocate during a puffing test, generating an internal and external pressure difference, such as... Figure 2 As indicated by the arrow, the smoke generated during inhalation flows from the electronic cigarette holding device 200 towards the direction of collection. Furthermore, the oil filter 700 is connected to the piston mechanism 400 via a gas flow channel. After the smoke enters the oil filter 700 and the e-liquid is separated, the remaining components flow out through the piston mechanism 400 for analysis and detection. The gas flow channel includes an inhalation conduit 610, a filter conduit 620, and an exhaust conduit 630. The clamping device, inhalation conduit 610, Cambridge filter, oil filter 700, filter conduit 620, piston mechanism 400, and exhaust conduit 630 are connected sequentially. Finally, the smoke generated by the electronic cigarette 100 in the electronic cigarette holding device 200 due to the pressure difference created by the driving device is separated from the e-liquid after entering the oil filter 700, and the remaining components of the smoke flow out through the exhaust conduit 630 via the piston mechanism 400.

[0065] Furthermore, the oil-gas separation mechanism is provided with a first baffle 7601 and a second baffle 7602 to form an oil-gas separation array. More specifically, the first baffle 7601 and the second baffle 7602 are arranged at an angle to the direction of the flue gas inlet of the inlet channel. Preferably, as shown... Figure 4As shown, the first baffle 7601 and the second baffle 7602 are arranged in a direction perpendicular to the inlet 710. A first grease separation port 762 and a second grease separation port 763 for flue gas to pass through are formed between the first baffle 7601, the second baffle 7602 and the housing of the oil filter device 700. The first baffle 7601 and the second baffle 7602 may each include at least one baffle. Preferably, the first baffle 7601 and the second baffle 7602 each include one baffle, and the first baffle 7601 and the second baffle 7602 form an alternating baffle group. Multiple baffle groups may be provided. The first e-liquid separation port 762 is positioned near the inlet channel, i.e., away from the grease drain plate 770, while the second e-liquid separation port 763 is positioned away from the inlet channel, i.e., near the grease drain plate 770. This creates a staggered effect between the positions of the first e-liquid separation port 762 and the second e-liquid separation port 763. When the smoke enters the inlet 710, it can pass through the baffle along a wave-like path from the first e-liquid separation port 762 and the second e-liquid separation port 763 to the outlet 720 within the oil filter device 700.

[0066] Furthermore, the first baffle 7601 has an oil leakage hole 761 at the far end of the inlet channel, that is, near the oil drain plate 770, so that the e-liquid slides down the first baffle 7601 to the oil leakage hole 761.

[0067] Furthermore, the drain port 731 is arranged on the opposite side of the inlet channel of the oil filter device 700, and the bottom of the oil filter device 700 is provided with an oil drain plate 770. Preferably, the oil drain plate 770 at least partially forms a height difference, and the oil drain port 731 is located at the lowest end of the oil drain plate 770, so that the separated e-liquid is guided by gravity by the oil drain plate 770 and slides to the oil drain port 731. Even further, the oil drain plate 770 is inclined downwards from the side away from the oil drain port 731, so that e-liquid sliding down from the multiple first baffles 7601 and second baffles 7602 is guided by the oil drain plate 770 through the oil leakage hole 761 and concentrated to the oil drain port 731. As another embodiment, the oil drain plate 770 can be shaped like a "V", with e-liquid sliding down from both sides towards the middle to the oil drain port 731.

[0068] Furthermore, at least one of the inlet and outlet channels includes a corner and / or an inclined baffle. In the following embodiments, it is described that both the inlet and outlet channels may include a corner and an inclined baffle, such as... Figure 3As shown, the angle α between the inclined baffle in the inlet channel and the flow direction of the smoke is less than 90°, so as to guide the e-liquid separated from the smoke into the oil-gas separation mechanism. The angle β between the inclined baffle in the outlet channel and the flow direction of the smoke is less than 90°, so as to prevent the e-liquid separated from the smoke from flowing out of the oil-gas separation mechanism. The corner section and the inclined baffle can form part of the waveform path of the smoke flow. Preferably, at least one corner section and one inclined baffle are provided in the oil filter device 700. The corner section includes a first corner channel 745 near the inlet 710 of the inlet channel and a second corner channel 746 near the outlet 720 of the outlet channel. The inclined baffle includes a first inclined baffle 751 near the first corner channel 745 and a second inclined baffle 752 near the second corner channel 746. More preferably, the flue gas flows sequentially through the inlet 710, the first corner channel 745, the first inclined baffle 751, the oil-gas separation mechanism, the second inclined baffle 752, the second corner channel 746, and the outlet 720.

[0069] Furthermore, the first sidewall 741 is located on the side away from the inlet 710, and the second sidewall 742 is located on the side closer to the inlet 710. The first sidewall 741 and the second sidewall 742 are arranged at an angle along the direction of the inlet 710, thereby forming a first corner channel 745 through which smoke enters from the inlet 710. Preferably, the first sidewall 741 and the second sidewall 742 are perpendicular to the direction of the inlet 710. The first inclined baffle 751 can be inclined downwards from either the first sidewall 741 or the second sidewall 742 to receive the e-liquid separated from the first sidewall 741 or the second sidewall 742, allowing the e-liquid to slide downwards through the first inclined baffle 751 to the outlet 731 under the influence of gravity. Preferably, the first inclined baffle 751 can be inclined downwards from the first sidewall 741 close to the inlet 710. When the smoke passes through the first corner channel 745, the flow direction of the smoke after entering from the inlet 710 is changed. Under the action of centrifugal force, the e-liquid in the smoke is thrown onto the first side wall 741, thus achieving the initial separation of e-liquid and smoke. Under the action of gravity, the e-liquid slides down through the first inclined baffle 751 to the oil outlet 731.

[0070] Furthermore, the third sidewall 743 is disposed on the side near the outlet 720, and the fourth sidewall 744 is disposed on the side away from the outlet 720. The third sidewall 743 and the fourth sidewall 744 are arranged at an angle along the direction of the outlet 720, thereby forming a second corner channel 746 from which the smoke exits the outlet 720. Preferably, the third sidewall 743 and the fourth sidewall 744 are perpendicular to the direction of the outlet 720. The second inclined baffle 752 can be inclined downward from the third sidewall 743 or the fourth sidewall 744 to receive the e-liquid separated on the third sidewall 743 or the fourth sidewall 744, and allow the e-liquid to slide downward through the second inclined baffle 752 to the oil outlet 731 under the action of gravity. Preferably, the second inclined baffle 752 is inclined downward from the third sidewall 743 close to the outlet 720. When the smoke carrying e-liquid passes through the second inclined baffle 752 and reaches the second corner channel 746, the flow direction of the smoke is turned to be horizontal with the outlet 720. Under the action of centrifugal force, the e-liquid in the smoke is thrown onto the third sidewall 743, thereby realizing the re-separation of e-liquid and smoke. Under the action of gravity, the e-liquid slides downward through the second inclined baffle 752 to the oil outlet 731. The first corner channel 745 and the second corner channel 746 can both constitute part of the waveform path of the smoke flow.

[0071] Furthermore, such as Figure 5 As shown, the oil drain port 731 is detachably equipped with an oil drain port cover 732. The oil drain port cover 732 can be closed during the vaping test. When the vaping test is over, the oil drain port cover 732 can be opened and the e-liquid can be discharged from the oil drain port cover 732.

[0072] Oil filtration mechanism such as Figure 6As shown, the oil filter device 700 should be kept horizontal during use, meaning the length direction of the baffle 760 should be aligned with the direction of gravity. During the suction test, the vapor carrying e-liquid droplets 780 enters the oil-gas separation mechanism from the inlet 710. At the first corner channel 745, due to the high density and inertia of the e-liquid droplets 780, they are thrown against the wall under centrifugal force. The accumulated e-liquid droplets 780 slide down the side wall and the first inclined baffle 751 to the oil outlet 731. Similarly, when the vapor carrying e-liquid droplets 780 flows from the second inclined baffle through the second corner channel 746 towards the outlet 720, the e-liquid droplets 780 slide down to the oil outlet 731 under centrifugal force. Furthermore, as the vapor carrying e-liquid droplets 780 passes through the baffle array 760, the droplets 780 are successively thrown onto the wall of each baffle 760 and slide down the wall, thus achieving multi-level e-liquid separation of the vapor. In addition, due to the long process, the larger e-liquid droplets 780 will settle due to gravity during the process. The e-liquid droplets 780 eventually converge to the drain plate 770 and flow through the drain hole 761 to the vicinity of the drain port 731, while the vapor components after the separation of e-liquid droplets 780 flow out from the outlet 720.

[0073] Compared to traditional smoke extraction systems, the oil filter 700 effectively reduces the amount of oil entering the drive unit, thereby improving the reliability of the drive unit's operation and extending its service life. Secondly, reducing the amount of oil entering the drive unit ensures that the smoke extraction system's set suction capacity does not deviate, thus improving the accuracy of related tests. On the other hand, traditional smoke extraction systems can only clean the oil inside the system by disassembling the suction pipe 610, filter pipe 620, and suction pipe 630 for rinsing. This is inconvenient to operate and makes it impossible to observe the oil accumulation inside the system, resulting in incomplete cleaning. However, the current oil filter 700 is made of transparent plexiglass, allowing for easy observation of the oil accumulation inside the system. The oil can also be quickly and conveniently discharged from the drain port 731 by opening the drain cover 732.
