Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an aerosol collection device and aerosol collection system. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by the dispersion and suspension of solid or liquid particles in a gaseous medium. They are typically formed by atomizing the atomizing medium using electronic atomization devices through methods such as heating or ultrasound. Aerosols can be absorbed by the human body through the respiratory system, providing users with a novel alternative absorption method.

[0003] To test the chemical composition of aerosols, it is necessary to first collect the aerosols. Current aerosol collection methods mainly include the Cambridge filter method, solution absorption method, cold hydrazine solution absorption method, and vacuum bag collection method. However, these collection methods still have problems such as low collection efficiency and complex operation, which are not conducive to subsequent chemical composition testing. Utility Model Content

[0004] Therefore, it is necessary to provide an aerosol collection device and aerosol collection system to address the problems of low collection efficiency and complex operation of aerosols.

[0005] An aerosol collection device, comprising:

[0006] Fixed components;

[0007] A data collection assembly includes a data collection chamber and a push rod. The data collection chamber is located within the fixing assembly. One end of the push rod extends into the data collection chamber along a first direction. The push rod and the data collection chamber together form a data collection cavity with an air inlet.

[0008] A movable component is installed at the end of the push rod located outside the collection chamber;

[0009] The push rod is capable of reciprocating between a first position and a second position along the first direction; the volume of the acquisition cavity when the push rod is in the first position is smaller than the volume of the acquisition cavity when the push rod is in the second position.

[0010] In one embodiment, the aerosol collection device further includes an air inlet pipe connected to the collection chamber and communicating with the air inlet.

[0011] In one embodiment, the fixing component includes a first fixing unit, the first fixing unit having a first limiting groove, and the collection chamber being located within the first limiting groove.

[0012] In one embodiment, the first fixing unit includes a fixing base and a fixing cover, the fixing cover being detachably mounted on the fixing base, and the fixing base and the fixing cover together forming the first limiting groove.

[0013] In one embodiment, the fixing component includes a second fixing unit connected to the first fixing unit, the second fixing unit having a second limiting groove; the collection chamber has a first limiting part, the first limiting part being limited in the second limiting groove.

[0014] In one embodiment, the fixing component further includes a first fastener, which is mounted on the second fixing unit, and one end of the second fastener extends into the second limiting groove and abuts against the first limiting portion along the first direction.

[0015] In one embodiment, the movable component includes a movable base located on one side of the fixed component in the first direction, and one end of the push rod is confined to the movable base.

[0016] In one embodiment, the movable seat is provided with a third limiting groove, and one end of the push rod is provided with a second limiting part, which is limited in the third limiting groove.

[0017] In one embodiment, the movable component further includes a second fastener mounted on the movable base, one end of which extends into the third limiting groove to abut against the second limiting portion.

[0018] An aerosol collection system includes the aforementioned aerosol collection device. The aerosol collection system further includes a driving device, which is tractively connected to the moving component. The driving device drives the push rod to reciprocate between the first position and the second position along the first direction via the moving component.

[0019] In one embodiment, the driving device includes a driving component and a transmission rod, one end of which is connected to the driving component and the other end of which is connected to the moving component.

[0020] The aforementioned aerosol collection device can be connected to an electronic atomizing device via pipes or other connecting structures. In the initial state, the push rod is in the first position. When the electronic atomizing device generates aerosol, the push rod moves along the first direction to the second position. The volume of the collection chamber increases while generating negative pressure, thereby drawing the aerosol into the collection chamber. Since this aerosol collection device can collect all the aerosol generated by the electronic atomizing device, it facilitates accurate subsequent quantitative chemical analysis. Furthermore, because the overall structure of the aerosol collection device is simple, requires no pipe cleaning, and is easy to disassemble, it can be reused, thus reducing testing costs and minimizing resource waste.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] See Figure 1 and Figure 2 This application provides an aerosol collection system 100 for collecting aerosols generated by an electronic atomizing device during operation, thereby facilitating subsequent testing of the aerosol's chemical composition. It is understood that in other embodiments, the aerosol collection system 100 may also be used to collect aerosols generated by other devices.

[0034] As described in the background section, based on the requirements of chemical composition testing, it is necessary to collect the aerosols generated by electronic atomization devices. Currently, the main methods for aerosol collection include the Cambridge filter method, solution absorption method, cold hydrazine solution absorption method, and vacuum bag collection method.

[0035] Among these methods, the Cambridge filter method primarily collects particulate matter from aerosols, achieving a collection efficiency of over 99% for particles larger than 0.3 μm. However, it cannot collect gaseous matter from aerosols. While solution absorption and cold hydrazine solution absorption can collect both particulate and gaseous matter from atomized aerosols, the short residence time of the atomized matter in the solvent due to its high throughput (18.3 mL / s) prevents complete collection. Vacuum bag collection, although capable of completely capturing aerosols within the bag, suffers from complex operating procedures, low pipeline cleaning efficiency, and the need for disposable gas sampling bags, making repeated use impossible.

[0036] To address the aforementioned technical issues, such as Figure 1 and Figure 2As shown, the aerosol collection system 100 of this application includes an aerosol collection device 20 and a driving device 40. The driving device 40 is connected to the aerosol collection device 20 by transmission. The aerosol collection device 20 collects aerosols generated by the electronic atomizing device under the drive of the driving device 40. In some embodiments, the aerosol collection system 100 may not include the driving device 40, and the aerosol collection device 20 may be driven manually to collect aerosols.

[0037] Specifically, the drive unit 40 has an installation platform on which the aerosol collection device 20 is installed, including a fixed component 21, a collection component 23 and a moving component 25.

[0038] The fixing component 21 is fixed to the mounting platform. The collection component 23 includes a collection chamber 232 and a push rod 234. The collection chamber 232 is confined within the fixing component 21. One end of the push rod 234 extends into the collection chamber 232 along a first direction. The push rod 234 and the collection chamber 232 together form a collection cavity 23a with an air inlet 232a. The moving component 25 is installed at the end of the push rod 234 located outside the collection chamber 232. The push rod 234 can reciprocate between a first position and a second position along the first direction. The volume of the collection cavity 23a when the push rod 234 is in the first position is smaller than the volume of the collection cavity 23a when the push rod 234 is in the second position.

[0039] Thus, the aerosol collection device 20 can be connected to the electronic atomizing device via a connecting structure such as a pipe. In the initial state, the push rod 234 is in the first position. When the electronic atomizing device generates aerosol, the push rod 234 moves to the second position along the first direction, and the volume of the collection chamber 23a increases while generating negative pressure, thereby drawing the aerosol into the collection chamber 23a.

[0040] Since the aforementioned aerosol collection device 20 can collect all the aerosols generated by the electronic atomization device, it facilitates accurate subsequent quantitative chemical analysis. Furthermore, because the aerosol collection device 20 has a simple overall structure, requires no pipeline cleaning, and is easy to disassemble, it can be reused, thereby reducing testing costs and minimizing resource waste.

[0041] Please continue reading. Figure 1 and Figure 2 In the following embodiments, the width direction of the fixing component 21 is defined as the first direction (i.e., Figure 1 The X direction in the middle), the length direction of the fixed component 21 is the second direction (i.e., Figure 1 The Y direction in the middle), the height direction of the fixed component 21 is the third direction (i.e. Figure 1 (in the Z direction), wherein the first direction, the second direction and the third direction intersect each other, preferably, the first direction, the second direction and the third direction are perpendicular to each other.

[0042] In some embodiments, the fixing component 21 includes a first fixing unit 212, which includes a fixing base 2121 and a fixing cover 2123. The driving device 40 includes a mounting platform, the fixing base 2121 is mounted on the mounting platform, and one end of the fixing cover 2123 is rotatably connected to one end of the fixing base 2121 in a second direction. The fixing base 2121 has a first sub-limiting groove 2121a with a semi-circular arc-shaped, inwardly recessed sidewall on the side facing the fixing cover 2123. The fixing cover 2123 has a second sub-limiting groove 2123a with a semi-circular arc-shaped, inwardly recessed sidewall on the side facing the fixing base 2121. The first sub-limiting groove 2121a and the second sub-limiting groove 2123a are correspondingly connected to form a first limiting groove.

[0043] Thus, the fixing cover 2123 is detachably mounted on the fixing base 2121 and together with the fixing base 2121 forms the first limiting groove. The shape of the first limiting groove matches the shape of the collection chamber 232 of the collection component 23, so the collection chamber 232 can be confined within the first limiting groove to prevent the collection chamber 232 from shaking. When it is necessary to disassemble or assemble the collection component 23, the fixing cover 2123 can be rotated in one direction to open the fixing cover 2123, so that the collection chamber 232 can be placed into or removed from the first sub-limiting groove 2121a. Then, the fixing cover 2123 can be locked by rotating it in the opposite direction.

[0044] In one further embodiment, a portion of the fixing base 2121 is supported on the mounting platform, while another portion of the fixing base 2121 is suspended in the air. A first sub-limiting groove 2121a is formed in the suspended portion of the fixing base 2121. The portion of the fixing base 2121 supported on the mounting platform has a sliding groove extending in a first direction. One end of a fastening bolt abuts against the fixing base 2121, and the other end of the fastening bolt passes through the sliding groove and is inserted into the mounting platform to fix the fixing base 2121 to the mounting platform, allowing the position of the fixing base 2121 relative to the mounting platform in the first direction to be adjustable as needed.

[0045] In some embodiments, the fixing assembly 21 further includes two second fixing units 214, which are spaced apart in a first direction. Each second fixing unit 214 includes a connecting portion 2141 and a fixing portion 2143. The connecting portions 2141 of the two second fixing units 214 can be respectively connected to the opposite ends of the fixing seat 2121 of the first fixing unit 212 in the first direction. Each connecting portion 2141 has a groove extending in the first direction. One end of the fastening bolt abuts against the connecting portion 2141, and the other end of the fastening bolt can pass through the groove and be inserted into the fixing seat 2121 to fix the connecting portion 2141 to the fixing seat 2121. The position of the second fixing unit 214 in the first direction can be adjusted by the groove.

[0046] The fixing parts 2143 of the two second fixing units 214 are located on one side of the fixing base 2121 in the first direction. Each fixing part 2143 is provided with a second limiting groove 2143a on the side facing the other fixing part 2143, and the second limiting groove 2143a passes through the fixing part 2143 in the first direction. The second limiting grooves 2143a of the two second fixing units 214 can be used together to limit the collection chamber 232 in the first direction.

[0047] Furthermore, the fixing component 21 also includes a first fastener 216, which is a fastening screw. The first fastener 216 is installed on the side of the second fixing unit 214 facing away from the first fixing unit 212 in the first direction. One end of the second fastener 254 extends into the second limiting groove 2143a along the first direction to further limit the collection chamber 232 of the collection component 23. Specifically, in one embodiment, each second fixing unit 214 is equipped with two first fasteners 216, and the two first fasteners 216 are arranged at intervals in the third direction to jointly limit the collection chamber 232.

[0048] The movable component 25 includes a movable seat 252, which is located on one side of the fixed component 21 and close to the second fixed unit 214 in the first direction. The two side walls of the movable seat 252 are bent toward the fixed component 21 in the second direction to form a third limiting groove 252a. One end of the push rod 234 of the acquisition component 23 is limited in the third limiting groove 252a to be limited in the movable seat 252.

[0049] Furthermore, the movable component 25 also includes a second fastener 254, which is a fastening screw. The second fastener 254 is installed on the side of the movable base 252 facing away from the fixed component 21. One end of the second fastener 254 extends into the third limiting groove 252a along the first direction to limit the push rod 234 of the acquisition component 23. Specifically, in one embodiment, two second fasteners 254 are installed on the movable base 252. The two second fasteners 254 are spaced apart in the second direction, thereby jointly limiting the push rod 234.

[0050] Thus, the drive device 40 is connected to the moving component 25, and the drive device 40 drives the push rod 234 of the acquisition component 23 to reciprocate along the first direction through the moving component 25.

[0051] The collection chamber 232 has a hollow cylindrical structure and includes a first end and a second end arranged opposite each other in a first direction. The first end has a protruding air inlet 232a for connecting to a pipe or other connecting structure, and the second end has a connecting port. One end of the push rod 234 can extend into the collection chamber 232 from the connecting port along the first direction. The end face of the push rod 234 and the collection chamber 232 together form a collection cavity 23a, and the end of the push rod 234 extending into the collection chamber 232 is provided with a sealing plug. The sealing plug is interference-fitted with the side wall of the collection chamber 232 to prevent aerosol in the collection cavity 23a from flowing out from the gap between the push rod 234 and the collection chamber 232. Specifically, in one embodiment, when the push rod 234 is in the first position, the sealing plug abuts against the first end face of the collection chamber 232, at which time the volume of the collection cavity 23a is at its minimum value and close to or equal to zero. When the push rod 234 is in the second position, the sealing plug is located at the second end of the collection chamber 232, and the volume of the collection cavity 23a is at its maximum value.

[0052] Furthermore, the second end of the collection chamber 232 is provided with a first limiting part 2321, which surrounds the second end circumferentially. A second limiting part 2341 is confined in a second limiting groove 2143a, and a first fastener 216 abuts against the first limiting part 2321, thereby fixing the collection chamber 232 relative to the fixing component 21 in a first direction. Moreover, by adjusting the length of the first fastener 216 extending into the second limiting groove 2143a, the first limiting part 2321 of different thicknesses can be fixed.

[0053] The push rod 234 has a second limiting part 2341 at one end outside the collection chamber 232. The second limiting part 2341 surrounds the push rod 234 circumferentially and is limited in the third limiting groove 252a of the movable seat 252. The second fastener 254 abuts against the second limiting part 2341, thereby fixing the push rod 234 relative to the movable seat 252. Moreover, by adjusting the length of the second fastener 254 extending into the second limiting groove 2143a, the second limiting part 2341 of different thicknesses can be fixed.

[0054] In some embodiments, the aerosol collection device 20 further includes an air inlet pipe, one end of which is connected to the collection chamber 232 and communicates with the air inlet 232a, and the other end of which is used to connect to the electronic atomizing device. Therefore, the aerosol generated by the electronic atomizing device enters the collection chamber 232 entirely through the air inlet pipe. It is understood that in some other embodiments, the aerosol collection device 20 may also be connected to the electronic atomizing device through other connection structures, which is not limited here.

[0055] In some embodiments, the drive device 40 includes a drive assembly 41 and a transmission rod 43. The drive assembly 41 includes a first drive module 412 and a second drive module 414. The second drive module 414 is disposed on one side of the first drive module 412 in a first direction, and the top wall of the other side of the first drive module 412 in the first direction forms a mounting platform. The transmission rod 43 has a screw-like structure extending along the first direction. One end of the transmission rod 43 is connected to the second drive module 414, and the other end of the transmission rod 43 is connected to the movable base 252.

[0056] Thus, the drive assembly 41 can drive the transmission rod 43 to reciprocate in the first direction, thereby driving the moving seat 252 to reciprocate in the first direction, and finally driving the push rod 234 of the acquisition assembly 23 to reciprocate in the first direction.

[0057] The working principle of the above-mentioned aerosol collection system 100 is as follows:

[0058] First, open the fixing cover 2123 of the first fixing unit 212, put the acquisition component 23 into the first sub-limiting groove 2121a, and then close the fixing cover 2123 to limit the acquisition chamber 232 of the acquisition component 23 in the first limiting groove. The first limiting part 2321 of the acquisition chamber 232 is limited in the second limiting groove 2143a of the second fixing unit 214, and the second limiting part 2341 of the push rod 234 is limited in the third limiting groove 252a of the moving seat 252.

[0059] Then, the electronic atomizing device is connected to the air inlet 232a of the collection chamber 232 through the air inlet pipe. At this time, the push rod 234 is in the first position and the volume of the collection chamber 23a is at its minimum value.

[0060] Then, the drive assembly 41 is activated. The drive assembly 41 drives the moving assembly 25 to move away from the collection chamber 232 via the transmission rod 43, thereby driving the push rod 234 to move away from the air inlet 232a of the collection chamber 232 to the second position. The volume of the collection chamber 23a gradually increases and forms a negative pressure. The aerosol generated by the electronic atomization device continuously enters the collection chamber 23a through the air inlet pipe, thereby realizing the collection of aerosol.

[0061] The aforementioned aerosol collection device 20 and aerosol collection system 100, with collection component 23 driven by drive device 40, can automatically collect all aerosols generated by the electronic atomization device, exhibiting high collection efficiency, thus facilitating subsequent accurate quantitative chemical analysis. Furthermore, the aerosol collection device 20 has a simple and reliable overall structure, is easy to disassemble for cleaning, and can be reused after cleaning, thereby effectively controlling collection costs and reducing resource waste.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
