[0002] With the rapid development of e-cigarettes, the safety of the components in e-cigarette emissions has received attention, and the technical requirements for detecting the components in e-cigarette emissions have also increased accordingly.

[0003] At present, the main methods for collecting e-cigarette emissions are Cambridge filters or solvent absorption through traps. Cambridge filters can capture particulate matter in the smoke, but there are still a small amount of gas phase components that cannot be completely captured, and Cambridge filters require subsequent processing steps such as oscillation extraction. Long-term processing may cause deviations in component results, which is not conducive to the study of e-cigarette emissions. Conventional solvent absorption can only capture certain specific components.

[0004] The low-temperature capture method can capture different volatile components in the electronic cigarette emissions, and can even capture the entire smoke components. However, the temperature of low-temperature capture is usually -70°C or even lower, and it is difficult for existing capture devices to maintain such low temperature conditions during the smoking process.

[0028] In order to facilitate the understanding of the utility model, the utility model is described in more detail in the following in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on another element, or there can be one or more centered elements therebetween.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figure 1 , Figure 1The schematic diagram of the structure of the electronic cigarette emission collection device in the prior art. The electronic cigarette emission collection device in the prior art includes an absorption bottle and an insulation barrel. The absorption bottle is placed in the insulation barrel. The absorption bottle stores an absorption solution corresponding to the emission components to be captured. Affected by the temperature difference between the condensate in the insulation barrel and the absorption solution in the absorption bottle, the heat in the absorption solution is lost and the temperature drops to a low temperature equivalent to that of the condensate. During operation, when the gas containing the emission is passed into the absorption bottle, the low-temperature absorption solution in the absorption bottle can capture the electronic cigarette emission in the gas and dissolve it in the absorption solution.

[0031] However, while the condensate lowers the temperature of the absorption bottle, the open design of the insulation barrel significantly increases the heat exchange area of ​​the condensate, resulting in a waste of cold energy in the insulation barrel. The temperature of the condensate further rises and the low temperature condition cannot be maintained for a long time.

[0032] See also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of a capture device provided in one embodiment of the present application. Figure 3 The schematic diagram of the cross-sectional structure of the capture device provided in one embodiment of the present application. The capture device includes a box body 10, a cover body 20 and an absorption bottle 30. An insulation layer 110 is provided inside the box body 10, and the insulation layer 110 divides the internal space of the box body 10 into a low-temperature chamber 140 on the upper side and a cooling chamber 130 on the lower side. Among them, the cooling chamber 130 is used to accommodate condensate, and the low-temperature chamber 140 is a cavity. The cover body 20 covers the box body 10, and forms a closed space with the low-temperature chamber 140 of the box body 10 to reduce the cold loss caused by the escape of cold air in the low-temperature chamber 140. The absorption bottle 30 is used to be inserted into the box body 10, and the absorption solution at the bottom of the absorption bottle 30 is located below the insulation layer 110, so as to provide low-temperature conditions for cooling the absorption solution through the cooling chamber 130, and the top of the absorption bottle 30 passes through the inside of the box body 10 and extends from the cover body 20 to facilitate the connection of the external gas source and introduce the gas into the absorption bottle 30.

[0033] The box body 10 is composed of a side wall 120 and a bottom wall (not shown in the figure), the side wall 120 is connected to the upper side of the bottom wall, and the side of the side wall 120 relative to the bottom wall is the opening of the box body 10. Specifically, a side wall insulation layer 121 is provided in the side wall 120 and the bottom wall to prevent the condensate in the box body 10 from exchanging heat with the outside through the side wall 120 and the bottom wall, causing excessive cold loss. In this embodiment, the side wall insulation layer 121 is made of insulation material, such as asbestos, polyurethane or other insulation coatings, etc., and is filled in the side wall 120. The side wall insulation layer 121 can also be a vacuum structure, and the heat conduction effect at the side wall insulation layer 121 is reduced by vacuum. In some other embodiments, the side wall insulation layer 121 can include multiple layers, for example, the insulation layer is designed as a double-layer composite insulation structure to improve the insulation effect under the condition of controlling cost. It is understandable that those skilled in the art can select a suitable insulation structure and insulation material according to the actual insulation requirements and in combination with the material cost.

[0034] See also Figure 4 , Figure 4 A schematic diagram of the cross-sectional structure of a capture device provided in an embodiment of the present application without an absorption bottle. The heat-insulating layer 110 is horizontally fixedly arranged inside the box body 10, dividing the internal space of the box body 10 into a cooling chamber 130 and a low-temperature chamber 140. Specifically, the heat-insulating layer 110 is also made of a heat-insulating material, and the heat-insulating layer 110 can reduce the heat conducted by the condensate in the cooling chamber 130 through the heat-insulating layer 110, thereby avoiding excessive loss of cold. A plurality of heat-insulating holes 111 are arranged on the heat-insulating layer 110, and the heat-insulating holes 111 are used for the absorption bottle 30 to pass through the heat-insulating layer 110 and reach the cooling chamber 130 below the heat-insulating layer 110. The shape of the heat-insulating layer 110 is adapted to the horizontal cross-sectional shape of the box body 10. If the box body 10 is a rectangular parallelepiped, the shape of the heat-insulating layer 110 is correspondingly designed to be rectangular; if the box body 10 is a cylinder, the shape of the heat-insulating layer 110 is correspondingly designed to be circular.

[0035] The cooling chamber 130 is surrounded by the bottom wall of the box body 10, part of the side wall 120 and the insulation layer 110, all of which are provided with insulation materials to reduce the heat exchange efficiency between the condensate in the cooling chamber 130 and the external environment. A plurality of grooves 131 are also provided in the cooling chamber 130, and the grooves 131 are used to receive the bottom of the absorption bottle 30. Specifically, the inner wall of the groove 131 is used to distinguish the inner side and the outer side of the groove 131, the inner side of the groove 131 (i.e., the side facing the absorption bottle 30) is used to receive the absorption bottle 30, and the outer side of the groove 131 is the cooling chamber 130, which is used to accommodate the condensate, so that the absorption bottle 30 and the condensate are isolated by the inner wall of the groove 131.

[0036] In addition, the heat insulating layer 110 can also be made of elastic heat-insulating material, and a cross cut is provided at the corresponding position just above the groove 131, so that the absorption bottle 30 can be inserted from the heat insulating layer 110, and the cross cut is restored after the absorption bottle 30 is pulled out.

[0037] The groove 131 is designed to be a shape that matches the bottom of the absorption bottle 30, so that the groove inner wall 131A of the groove 131 can fit the bottom of the absorption bottle 30, thereby reducing the gap between the absorption bottle 30 and the groove inner wall 131A, and improving the heat exchange efficiency. The groove inner wall 131A can isolate the condensate from the absorption bottle 30, so that when the absorption bottle 30 needs to be inserted or pulled out of the box body 10, the condensate is not taken away, thereby avoiding the loss of condensate. The groove inner wall 131A is made of heat exchange material with a high thermal conductivity, so that the condensate can transfer cold energy to the inner wall of the groove 131, and then the groove inner wall 131A transfers cold energy to the bottle wall of the absorption bottle 30, and finally the bottle wall of the absorption bottle 30 provides cold energy to the absorption solution to reduce the temperature of the absorption solution, thereby achieving the required low temperature conditions for capturing electronic cigarette releases.

[0038] Specifically in the embodiment, since two absorption bottles 30 are usually set as a group, the number of grooves 131 is also set to 2. Of course, the grooves 131 can also be set to other numbers to meet different detection requirements, such as 4, 6 or 8, and multiple grooves 131 are evenly distributed in the cooling chamber 130. For example, 6 grooves 131 are distributed along the circumferential direction of the box body 10, with the horizontal geometric center of the box body 10 in a central symmetrical manner. Multiple absorption bottles 30 are inserted into the groove 131 together, and are cooled by the condensate in the cooling chamber 130 to provide a low temperature effect, thereby improving the utilization efficiency of the condensate. Of course, the more absorption bottles 30 are inserted, the more cold energy is consumed during the corresponding absorption experiment, so the capacity of the cooling chamber 130 should also be designed to be larger, so that when multiple absorption bottles 30 are inserted into the groove 131 for low-temperature capture of electronic cigarette release, the lost cold energy will not significantly increase the temperature in the cooling chamber 130.

[0039] In addition to having a high thermal conductivity, the inner wall 131A of the groove may also be made of an elastic material with certain shrinkage properties. Specifically, the inner diameter of the groove 131 is set to be no larger than the outer diameter of the absorption bottle 30. Specifically, in the embodiment, the inner diameter of the groove 131 may be set to be slightly smaller than the outer diameter of the absorption bottle 30. Thus, when the absorption bottle 30 is inserted into the groove 131, the groove 131 is squeezed by the absorption bottle 30 to produce a small amount of shrinkage deformation. Under the force generated by the shrinkage deformation, the inner wall 131A of the groove can be closely attached to the bottle wall of the absorption bottle 30, thereby fixing the absorption bottle 30 and reducing the gap between the inner wall 131A of the groove and the absorption bottle 30.

[0040] The depth of the groove 131 corresponds to the height of the absorption solution in the absorption bottle 30. For example, if the liquid level of the absorption solution in the absorption bottle 30 is significantly greater than the depth of the groove 131, it is inevitable that part of the absorption solution cannot be directly cooled by the inner wall 131A of the groove, so that the temperature difference of the temperature distribution of the absorption solution is large, and the low temperature conditions required for capturing the electronic cigarette release cannot be met. If the liquid level of the absorption solution is significantly lower than the depth of the groove 131, it may be necessary to pour too much condensate into the cooling chamber 130, resulting in waste of condensate and increased costs. At the same time, excessive condensate may also have an adverse effect on the part of the absorption bottle 30 where there is no absorption solution, which will be described in detail later and will not be introduced here. The absorption solution contained in the absorption bottle 30 is usually 10mL-20mL, and the depth of the groove 131 is at least 5cm, preferably 5cm in this embodiment. On this basis, those skilled in the art can further consider increasing the depth of the groove 131 based on the actual capacity (or liquid level) of the absorption solution in the absorption bottle 30 and the cost.

[0041] The cooling chamber 130 is also provided with a liquid injection port 112, so as to inject or pour out the condensate into or into the cooling chamber 130. Specifically, in some embodiments, the liquid injection port 112 is provided on the heat insulating layer 110 to connect the cooling chamber 130 and the low temperature chamber 140. A sealing cover or a sealing plug is provided on the liquid injection port 112, and when the condensate needs to be injected, the sealing cover can be opened; when the condensate is injected, the sealing cover is closed, so as to prevent the condensate in the cooling chamber 130 from leaking from the liquid injection port 112.

[0042] See also Figure 5 , Figure 5A schematic diagram of the cross-sectional structure of a capture device provided in another embodiment of the present application. In some other embodiments, the liquid injection port is divided into a liquid inlet 132 and a liquid outlet 133, the liquid inlet 132 is used to introduce condensate into the cooling chamber 130, and the liquid outlet 133 is used to discharge condensate from the cooling chamber 130. Specifically, the liquid inlet 132 and the liquid outlet 133 are respectively arranged on opposite sides of the side wall 120 of the box body 10. Among them, the liquid inlet 132 is close to the bottom of the cooling chamber 130, connected to an external cold source, and pumps the condensate with a lower temperature into the cooling chamber 130. The liquid outlet 133 is close to the top of the cooling chamber 130, and is also connected to an external cold source, and pumps the condensate with a relatively high temperature back into the cold source. The liquid injection port 112 can be provided on the insulation layer 110 with integrated import and export functions, or the liquid inlet 132 and the liquid outlet 133 can be provided on the side wall 120 of the box body, respectively, depending on the temperature change amplitude in the cooling chamber 130 and the requirements for low temperature conditions for absorbing the electronic cigarette release. For example, when the condensate is injected using the liquid injection port 112 (i.e., the condensate is not updated during the absorption of the release), if the experiment is carried out for 1h, the temperature changes from -110℃ to -108℃, and the experimental low temperature conditions for low temperature conditions below -100℃ can be regarded as acceptable errors and ignored, so the experiment can still be continued. If the temperature changes to above -100℃ as the experimental time increases, the condensate must be replaced again, or the liquid inlet 132 and the liquid outlet 133 are used to continuously provide coldness through an external cold source to keep the condensate temperature at -110℃. Relatively speaking, the temperature control in the form of connecting the cold source is more accurate and stable, but it is subject to the cold source and pipeline connection, and the complexity of the experiment is relatively high.

[0043] It should be noted that the cold source has storage, refrigeration and suction functions, which are specifically selected by those skilled in the art according to actual conditions and are not limited to this.

[0044] See also Figure 6 , Figure 6Another schematic diagram of the cross-sectional structure of the capture device provided in one embodiment of the present application. The low-temperature chamber 140 is located on the upper side of the heat-insulating layer 110, and serves as a temperature transition zone, which is used to ensure that the portion of the absorption bottle 30 that is above the liquid level of the absorption solution, especially the nozzle of the absorption bottle 30, will not be frozen. Specifically, since the temperature provided by the condensate is extremely low compared to the conventional room temperature, if a condenser is used, the outer surface of the condenser will freeze on the outer surface of the condenser due to the low temperature, and the water vapor in the air will freeze on the outer surface of the condenser. Since the condenser covers the entire absorption bottle 30, the nozzle of the absorption bottle 30 will usually be frozen due to its proximity to the condenser, resulting in the air guide tube 310 of the absorption bottle 30 being unable to be pulled out from the nozzle, and the absorption solution in the absorption bottle 30 cannot be directly tested, and the air guide tube 310 must be pulled out after the nozzle of the absorption bottle 30 is thawed, and the absorption solution can be sampled and tested. In the embodiment of the present application, the absorption bottle 30 located in the cooling chamber 130 is indirectly in contact with the cooling solution through the inner wall of the groove 131 for heat exchange, and there is very little gap between the absorption bottle 30 and the inner wall 131A of the groove, so it will not be frozen. The absorption bottle 30 located in the low-temperature chamber 140 is affected by the temperature in the cooling chamber 130, and the temperature is still relatively low. However, the low-temperature chamber 140 is almost airtight, so the air humidity in the low-temperature chamber 140 is generally low, which is not enough to freeze on the surface of the absorption bottle 30. The absorption bottle 30 passing through the low-temperature chamber 140 and located in the box body 10, although the air humidity is greater than that of the low-temperature chamber 140 due to being placed in the external environment, its temperature is higher than that of the low-temperature chamber 140. The moisture in the air here is not enough to freeze on the surface of the absorption bottle 30 in a short time, so the pipe mouth of the absorption bottle 30 can still be freely plugged in and out of the air guide tube 310. When the absorption process is completed, the air guide tube 310 can be directly pulled out from the absorption bottle 30 without waiting for the absorption bottle 30 to thaw, thereby improving the detection efficiency.

[0045] Please refer again Figure 4The cover 20 covers the upper side of the box body 10, and the cover 20 and the low-temperature chamber 140 together form a closed space, so that the cold air in the low-temperature chamber 140 is difficult to circulate with the outside. Specifically, a plurality of through holes 220 are provided on the cover 20, wherein each through hole 220 is arranged opposite to a heat insulation hole 111 on the heat insulation layer 110 and a groove 131 in the cooling chamber 130, and the inner diameter of the through hole 220 is equal to the outer diameter of the absorption bottle 30, so that the absorption bottle 30 can be inserted into the box body 10 through the through hole 220. At the same time, the through hole 220 also plays a limiting role for the absorption bottle 30. Under the joint action of the groove 131, the heat insulation hole 111 and the through hole 220, the position of the absorption bottle 30 after being inserted into the box body 10 is more stable, and it can resist external forces to a certain extent to avoid tipping. In some embodiments, if some through holes 220 are not inserted into the absorption bottle 30, a sealing plug can be used to insert the through hole 220 to prevent the cold air in the low-temperature chamber 140 from circulating with the outside through the through hole 220. Of course, even if the sealing plug is not inserted, only a small part of the cold air in the low-temperature chamber 140 is still circulated with the outside, so that the impact on the temperature in the low-temperature chamber 140 is very limited, and the impact on the cooling chamber 130 is negligible. Specifically in the embodiment, a cover insulation layer 210 is provided on the inner side of the cover body 20, and the cover insulation layer 210 is used to reduce the cold amount of the low-temperature chamber 140 from being lost to the outside through the cover body 20. As a result, the low-temperature chamber 140 is surrounded by the side wall insulation layer 121 of the box body, the insulation layer 110 and the cover insulation layer 210, thereby ensuring that the temperature of the low-temperature chamber 140 is at a relatively low level.

[0046] Please refer again Figure 6 The absorption bottle 30 includes a bottle body 320 and an air guide tube 310 inserted into the bottle body 320. The bottle body 320 stores an absorption solution. The air guide tube 310 includes an air inlet tube 311 and an air outlet tube 312. The air inlet end of the air inlet tube 311 is connected to an external gas source to introduce gas containing electronic cigarette releases. The air outlet end of the air inlet tube 311 is inserted into the absorption solution of the absorption bottle 30, so that when the gas enters the absorption solution, the electronic cigarette releases are dissolved in the absorption solution. The air guide tube 310 is inserted from the bottle mouth of the absorption bottle 30 and seals the bottle mouth of the absorption bottle 30. When the absorbed gas emerges from the liquid surface of the absorption solution, it can only be guided out of the absorption bottle 30 from the air outlet tube 312. After the absorption is completed, the absorption bottle 30 is pulled out of the box body 10 as a whole, and then the air guide tube 310 is pulled out from the tube mouth of the absorption bottle 30, and the absorption solution in the absorption bottle 30 can be sampled and tested to determine the electronic cigarette emission components contained in the gas.

[0047] When used in a specific application, the electronic cigarette emission capture device also includes at least one gas source and a vacuum pump. The gas source is used to provide gas containing electronic cigarette emissions, the purpose of which is to simulate the gas generated when the electronic cigarette is working, and the gas includes a variety of different emissions. Specifically, the emissions generated when the electronic cigarette is working include volatile substances in the smoke liquid, substances produced by decomposition during heating, leached heavy metals and some other compounds such as polycyclic aromatic hydrocarbons. Different types of emissions may require different absorption solutions, so multiple electronic cigarette emission capture devices are required for comparative experiments. At the same time, since a single absorption bottle 30 may not be sufficient to completely absorb the emissions in the gas, multiple absorption bottles 30 are required to be connected in series to form an electronic cigarette emission capture device to ensure complete absorption of the emissions, so as to accurately detect the components of the emissions in the gas. The vacuum pump is used to simulate the human lungs for suction to achieve directional flow of gas.

[0048] Specifically in the embodiment, first, condensate is injected into the cooling chamber 130 in the box body 10, and then the gas source is connected to the electronic cigarette emission capture device, specifically connected to the air inlet pipe 311 of one of the absorption bottles 30, and the air outlet pipe 312 of the absorption bottle 30 is connected in series to the air inlet pipe 311 of another absorption bottle 30, and then the two absorption bottles 30 are simultaneously inserted into the box body 10 to perform low-temperature capture of the electronic cigarette emissions in the gas. It can be understood that in some other embodiments, those skilled in the art can also set more absorption bottles 30 to be inserted into the box body 10 at the same time, and the absorption bottles 30 can be connected in series with each other. Finally, the air outlet pipe 312 of the absorption bottle 30 at the end of the series connection is connected to a vacuum pump.

[0049] In summary, the electronic cigarette emission capture device provided by the present application stores the condensate in the cooling cavity of the box body and isolates the condensate from the absorption bottle through the groove to avoid the loss of the condensate during the plugging and unplugging process. At the same time, the cooling cavity is surrounded by the insulation layer and the heat insulation layer of the box body, and the loss of cold to the surrounding environment is relatively small, which is conducive to maintaining the low temperature environment of the cooling cavity, thereby improving the accuracy of the absorption bottle in capturing the electronic cigarette emission at low temperature. The multiple grooves set in the cooling cavity are also convenient for users to select the number of absorption bottles to be inserted according to actual experimental needs, and the use is more flexible. And multiple absorption bottles can use the condensate to cool down together, and the utilization efficiency of the condensate is relatively high. A low-temperature cavity is also set on the upper side of the insulation layer. The low-temperature cavity is not directly cooled by the condensate, the temperature is relatively low, and the total amount of water in the air in the low-temperature cavity is small, so it will not freeze on the outer wall and the mouth of the absorption bottle, which is convenient for taking out the air guide tube immediately after the absorption experiment is completed, and sampling and testing the absorption solution, further improving the experimental efficiency.
