Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0030] In the present application, unless otherwise clearly specified and limited, if terms such as "mounted", "connected", "coupled", "fixed", etc. appear, these terms should be understood in a broad sense.

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 intermediate element at the same time. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0033] Refer to Figure 1 and Figure 2 An aerosol collection system 100 provided by an embodiment of the present application is used to collect the aerosol generated during the operation of an electronic atomization device, so as to facilitate subsequent testing of the chemical components of the aerosol. It can be understood that in some other embodiments, the aerosol collection system 100 can also be used to collect the aerosol generated by other devices.

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

[0035] Among them, the Cambridge filter method mainly collects the particulate phase in the aerosol, and the collection efficiency of particulate matter with a particle size of more than 0.3 μm can reach more than 99%, but it cannot collect the gaseous phase in the aerosol. Although the solution absorption method and the cold trap solution absorption method can collect the particulate phase and the gaseous phase in the atomized aerosol, since the atomized matter passes through at a rate of 18.3 mL / s and its residence time in the solvent is short, the effect of complete capture cannot be achieved. The vacuum bag collection method can completely capture the aerosol in the gas bag, but its operating device is complex, the pipeline cleaning efficiency is low, and at the same time, it requires the consumption of a disposable gas sampling bag and cannot be reused.

[0036] For the above technical problems, such as Figure 1 and Figure 2As shown, the aerosol collection system 100 of the present application includes an aerosol collection device 20 and a driving device 40. The driving device 40 is connected to the aerosol collection device 20 in a transmission manner. The aerosol collection device 20 collects the aerosol generated by the electronic atomization device under the drive of the driving device 40. In some embodiments, the aerosol collection system 100 may also not include the driving device 40, but manually drive the aerosol collection device 20 to collect aerosol.

[0037] Specifically, the driving device 40 has a mounting platform, and the aerosol collecting device 20 is mounted on the mounting platform, and includes a fixing component 21 , a collecting component 23 and a moving component 25 .

[0038] The fixed component 21 is fixed on the mounting platform, and the collection component 23 includes a collection chamber 232 and a push rod 234. The collection chamber 232 is limited to the fixed component 21, and one end of the push rod 234 extends into the collection chamber 232 along the first direction. The push rod 234 and the collection chamber 232 are jointly constructed to form a collection chamber 23a with an air inlet 232a. The moving component 25 is installed at one 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 chamber 23a when the push rod 234 is in the first position is smaller than the volume of the collection chamber 23a when the push rod 234 is in the second position.

[0039] In this way, the aerosol collection device 20 can be connected to the electronic atomization device through a connection structure such as a pipe. In the initial state, the push rod 234 is in the first position. When the electronic atomization device generates aerosol, the push rod 234 moves along the first direction to the second position, 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 aerosol collection device 20 can collect all aerosols generated by the electronic atomization device, it is convenient for subsequent accurate chemical quantitative analysis. Moreover, since the overall structure of the aerosol collection device 20 is simple, no pipeline cleaning and other operations are required and it is easy to disassemble, it can be reused, thereby reducing the testing cost and reducing the waste of resources.

[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 length direction of the fixing component 21 is the second direction (i.e. Figure 1 The height direction of the fixing component 21 is the third direction (i.e. Figure 1 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, and the first fixing unit 212 includes a fixing base 2121 and a fixing cover 2123. Among them, 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 the second direction. On the side of the fixing base 2121 facing the fixing cover 2123, a first sub-limiting groove 2121a with a semi-circular arc-shaped side wall and recessed inward is formed. On the side of the fixing cover 2123 facing the fixing base 2121, a second sub-limiting groove 2123a with a semi-circular arc-shaped side wall and recessed inward is formed. The first sub-limiting groove 2121a and the second sub-limiting groove 2123a are correspondingly communicated to jointly form a first limiting groove.

[0043] In this way, the fixing cover 2123 is openably and closably mounted on the fixing base 2121 and jointly forms a first limiting groove with the fixing base 2121. The shape of the first limiting groove matches the shape of the collection bin 232 of the collection component 23. Therefore, the collection bin 232 can be limited in the first limiting groove to prevent the collection bin 232 from shaking. When it is necessary to disassemble and 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 bin 232 can be placed into or taken out from the first sub-limiting groove 2121a, and then the fixing cover 2123 can be buckled by rotating the fixing cover 2123 in the opposite direction.

[0044] Further, in an embodiment, a part of the fixing base 2121 is supported on the mounting platform, and another part of the fixing base 2121 is suspended. The first sub-limiting groove 2121a is formed in the suspended part of the fixing base 2121. A sliding groove extending in the first direction is formed in the part of the fixing base 2121 supported on the mounting platform. One end of the fastening bolt abuts against the fixing base 2121, and the other end of the fastening bolt passes through the sliding groove and inserts into the mounting platform to fix the fixing base 2121 on the mounting platform, and the position of the fixing base 2121 relative to the mounting platform in the first direction can be adjusted as needed.

[0045] In some embodiments, the fixing assembly 21 further includes two second fixing units 214. The two second fixing units 214 are spaced apart in the 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 opposite ends of the fixing base 2121 of the first fixing unit 212 in the first direction. Each connecting portion 2141 is provided with a chute 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 chute and insert into the fixing base 2121 to fix the connecting portion 2141 to the fixing base 2121, and the position of the second fixing unit 214 in the first direction can be adjusted through the chute.

[0046] The fixing portions 2143 of the two second fixing units 214 are located on one side of the fixing base 2121 in the first direction. On one side of each fixing portion 2143 facing the other fixing portion 2143, a second limiting groove 2143a is provided, and the second limiting groove 2143a penetrates through the fixing portion 2143 in the first direction. The second limiting grooves 2143a of the two second fixing units 214 can be jointly used to limit the collection bin 232 in the first direction.

[0047] Furthermore, the fixing assembly 21 further includes a first fastener 216. The first fastener 216 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 in the first direction to further limit the collection bin 232 of the collection assembly 23. Specifically, in one embodiment, two first fasteners 216 are installed on each second fixing unit 214, and the two first fasteners 216 are arranged at intervals in the third direction, so as to jointly limit the collection bin 232.

[0048] The moving assembly 25 includes a moving base 252. The moving base 252 is located on one side of the fixing assembly 21 in the first direction and is close to the second fixing unit 214. The side walls on both sides of the moving base 252 in the second direction are bent towards the fixing assembly 21 to form a third limiting groove 252a. One end of the push rod 234 of the collection assembly 23 is limited in the third limiting groove 252a to be limited to the moving base 252.

[0049] Furthermore, the moving assembly 25 further includes a second fastener 254. The second fastener 254 is a fastening screw. The second fastener 254 is installed on the side of the moving base 252 facing away from the fixing assembly 21. One end of the second fastener 254 extends into the third limiting groove 252a in the first direction to limit the push rod 234 of the collection assembly 23. Specifically, in one embodiment, two second fasteners 254 are installed on the moving base 252, and the two second fasteners 254 are arranged at intervals in the second direction, so as to jointly limit the push rod 234.

[0050] In this way, the driving device 40 is transmission-connected to the moving assembly 25 , and the driving device 40 drives the push rod 234 of the collecting assembly 23 to move back and forth along the first direction through the moving assembly 25 .

[0051] The collection chamber 232 is a hollow cylindrical structure. The collection chamber 232 includes a first end and a second end arranged opposite to each other in a first direction. The first end is provided with an air inlet 232a for connecting with a connecting structure such as a pipeline, and the second end is provided with 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 surface of one end of the push rod 234 and the collection chamber 232 together form a collection chamber 23a. A sealing plug is provided at the end of the push rod 234 extending into the collection chamber 232. The sealing plug is interference-fitted with the side wall of the collection chamber 232, thereby preventing the aerosol in the collection chamber 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 surface of the collection chamber 232. At this time, the volume of the collection chamber 23a is the minimum value and is 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 chamber 23a is at a maximum value.

[0052] Furthermore, a first limiting portion 2321 is provided at the second end of the collection bin 232, the first limiting portion 2321 surrounds the second end in the circumferential direction, the second limiting portion 2341 is limited in the second limiting groove 2143a, and the first fastener 216 abuts against the first limiting portion 2321, so that the collection bin 232 is fixed in the first direction relative to the fixing assembly 21. Moreover, by adjusting the length of the first fastener 216 extending into the second limiting groove 2143a, the first limiting portions 2321 of different thicknesses can be fixed.

[0053] A second limiting portion 2341 is provided at one end of the push rod 234 located outside the collection chamber 232. The second limiting portion 2341 surrounds the push rod 234 in the circumferential direction. The second limiting portion 2341 is limited in the third limiting groove 252a of the moving seat 252. The second fastener 254 abuts against the second limiting portion 2341, so that the push rod 234 is fixed relative to the moving seat 252. Moreover, by adjusting the length of the second fastener 254 extending into the second limiting groove 2143a, the second limiting portion 2341 with different thicknesses can be fixed.

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

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

[0056] In this way, the driving 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 collection assembly 23 to reciprocate in the first direction.

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

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

[0059] Then, connect the electronic atomization device 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 the minimum value.

[0060] After that, start the driving assembly 41. The driving assembly 41 drives the moving assembly 25 to move away from the collection chamber 232 through 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, and the aerosol generated by the electronic atomization device continuously enters the collection chamber 23a through the air inlet pipe, thereby realizing the collection of the aerosol.

[0061] For the above aerosol collection device 20 and aerosol collection system 100, the collection assembly 23 can automatically collect all the aerosol generated by the electronic atomization device under the drive of the driving device 40, with high collection efficiency, which is convenient for subsequent accurate chemical quantitative analysis. Moreover, the overall structure of the aerosol collection device 20 is simple and reliable, easy to disassemble for cleaning, and can be reused after cleaning, thereby effectively controlling the collection cost and reducing the waste of resources.

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

[0063] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
