Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 One embodiment of this application provides an aerosol collection device for use in conjunction with an atomizing device 30, comprising:

[0035] At least one collection container 10, the collection container 10 being provided with a test solution for absorbing aerosols;

[0036] The first collection pipe 20 has one end connected to the atomizing device 30 and the other end extended into the test solution in the collection container 10, for collecting the aerosol generated by the atomizing device 30.

[0037] The anti-spray liquid structure 40 is installed on the first collection pipe 20 and is used to recover the liquid in the aerosol flowing through the first collection pipe 20.

[0038] In this embodiment, the aerosol collection device is used to collect the aerosols generated after the atomizing device 30 atomizes the aerosol matrix. The atomizing device 30 is used to atomize the aerosol matrix to generate absorbable aerosols. In this application, the atomizing device 30 is used as an apparatus for generating aerosols in atomization test experiments.

[0039] In this embodiment, the first collection pipe 20 is used to connect the aerosol collection device and the atomizing device 30, so that the aerosol generated by the atomizing device 30 enters the aerosol collection device through the first collection pipe 20.

[0040] In this embodiment, the anti-spray liquid structure 40 is used to prevent the spray liquid in the aerosol generated by the atomizing device 30 from entering the aerosol collection device along with the aerosol flow, thus affecting the stability and reliability of subsequent test results. Specifically, when the aerosol carrying spray liquid flows through the first collection pipe 20, the anti-spray liquid structure 40 installed on the first collection pipe 20 recovers the liquid in the aerosol, reducing or removing the liquid content in the aerosol. The aerosol with the recovered liquid then enters the aerosol collection device along the first collection pipe 20 and is collected by the aerosol collection device.

[0041] In one embodiment, please refer to Figure 2 The anti-spray liquid structure 40 includes at least one receiving cavity 400, which is disposed inside the first collection pipe 20. At least a portion of the receiving cavity 400 is located below the conveying direction of the first collection pipe 20 along the direction of gravity.

[0042] The receiving cavity 400 allows the liquid in the aerosol entering the first collecting pipe 20 to adhere to and collect in the receiving cavity 400 due to natural factors such as gravity, the adhesion of the liquid itself, and the surface tension of the liquid, thus converging below the first collecting pipe 20 to ensure the recovery of the liquid and achieve the collection of liquid in the aerosol.

[0043] In this embodiment, it should be noted that the collection effect of the aerosol can also be affected by factors such as the roughness of the inner wall of the first collection pipe 20 and the receiving cavity 400, the flow rate of the aerosol, and the pressure in the first collection pipe 20 and the receiving cavity 400. Therefore, in actual situations, the above-mentioned influencing factors can be adjusted or controlled according to the needs to obtain the desired aerosol collection effect.

[0044] In one embodiment, please refer to Figure 1 and Figure 2 The receiving cavity 400 is spherical in shape, and the inner diameter of the receiving cavity 400 is larger than the diameter of the first collecting pipe 20.

[0045] In this embodiment, the specific shape of the sphere is not limited; it can be a sphere or an ellipsoid, etc. The purpose of this shape is to facilitate the cleaning and reuse of the anti-spray structure 40. In practical use, the spherical shape makes cleaning easier for the user. A cleaning tool similar to a cup brush can be directly inserted into the storage cavity 400 for cleaning. Furthermore, the spherical structure eliminates hard-to-clean areas such as right angles or bends inside the storage cavity 400, making it easy to clean and allowing for the reuse of the anti-spray structure 40, thus saving costs. In practice, ultrasonic cleaning can also be used to clean the anti-spray structure 40, but this method would increase costs compared to the above methods.

[0046] In this embodiment, the inner diameter of the receiving cavity 400 is set to be larger than the diameter of the first collection pipe 20. The purpose is to ensure that the receiving cavity 400 has enough space so that the aerosol first fills the receiving cavity 400 before entering the collection container 10, thereby allowing the aerosol to stay in the receiving cavity 400 for a sufficient time to ensure that the liquid in the aerosol can adhere to and collect in the receiving cavity 400.

[0047] In this embodiment, the first collection pipe 20 can also be a pipe with multiple curved sections, such as a wavy pipe or a spiral pipe. In this case, the inner diameter of the receiving cavity 400 is not limited to being larger than the inner diameter of the first collection pipe 20, and the receiving cavity 400 is formed at the bend of the first collection pipe 20. It is understood that this structure is not easy to clean directly using cleaning components that extend into it; generally, cleaning is performed by ultrasonic waves.

[0048] In one embodiment, please refer to Figure 2 The anti-spray liquid structure 40 is integrally formed with the first collection pipe 20. At least a portion of the first collection pipe 20 has a protrusion 200 protruding outward from the pipe wall of the first collection pipe 20. The protrusion 200 is an anti-spray liquid structure. The receiving cavity 400 is formed in the protrusion 200 and is connected to the first collection pipe 20.

[0049] In this embodiment, the anti-spray liquid structure 40 is integrally formed with the first collection pipe 20, which facilitates production. The first collection pipe 20 has a protrusion 200 that protrudes outward along the direction of gravity. A receiving cavity 400 is formed inside the protrusion 200 and communicates with the first collection pipe 20. That is, the receiving cavity 400 is formed by protruding outward from the first collection pipe 20, so that the receiving cavity 400 has a larger space than the inner diameter of the first collection pipe 20 to receive the liquid in the aerosol. This allows the aerosol to first fill the inside of the receiving cavity 400 when it enters, so that it can stay for a sufficient time, allowing the spray liquid in the aerosol to adhere to the inner wall of the receiving cavity 400 and be collected inside the receiving cavity 400.

[0050] In one embodiment, please refer to Figure 2 and Figure 3 The anti-spray liquid structure 40 includes a recovery component 41, a receiving cavity 400 formed within the recovery component 41, and a first collection pipeline 20 including a first pipeline section 21 and a second pipeline section 22. The recovery component 41 is detachably connected to the first pipeline section 21 and the second pipeline section 22 respectively. The end of the first pipeline section 21 away from the recovery component 41 is connected to the atomizing device 30, and the end of the second pipeline section 22 away from the recovery component 41 extends into the test solution in the collection container 10.

[0051] The recycling component 41 may also have a protrusion 200 that protrudes outward along the direction of gravity, and a receiving cavity 400 is formed in the protrusion 200 and connected to the first collection pipe 20.

[0052] In this embodiment, the anti-spray liquid structure 40 is made into a detachable structure similar to the recovery component 41, making it easy to install, disassemble and clean, and convenient for users to use and replace.

[0053] In one embodiment, the recyclable component 41 is detachably connected to the first pipeline segment 21 and the second pipeline segment 22 via a locking structure 50. In one example, the locking structure 50 is a bolt-like clamp or the like.

[0054] In one embodiment, please refer to Figure 5 The receiving cavity 400 is provided with an absorption section 401, which is used to absorb the liquid recovered in the receiving cavity 400.

[0055] Alternatively, please refer to Figure 6 The anti-spray liquid structure 40 also includes a collection chamber 421, which is located below the receiving chamber 400 along the direction of gravity and is connected to the receiving chamber 400. The collection chamber 421 is used to collect the liquid recovered in the receiving chamber 400. Furthermore, the anti-spray liquid structure 40 also includes a collection component 42, in which the collection chamber 421 is located. The receiving chamber 400 has a mounting hole 402 on one side along the direction of gravity. One end of the collection component 42 is detachably connected to the recovery component 41 through the mounting hole 402, and the collection chamber 421 is connected to the receiving chamber 400.

[0056] In this embodiment, the absorption section 401 can further absorb the recovered liquid in the collection cavity 400, preventing the liquid that has flowed into the collection cavity 400 from flowing out of the collection cavity 400 again, thus affecting the collection effect of the liquid. In one example, the absorption section 401 is a material or structure that can absorb liquid, such as condensation cotton.

[0057] In this embodiment, the collecting component 42 collects the liquid in the receiving cavity 400 through its internal collecting cavity 421. Since one end of the collecting component 42 is detachably connected to the recovery component 41 through the mounting hole 402, during use, the liquid in the receiving cavity 400 enters the collecting cavity 421 of the collecting component 42 due to gravity. When the liquid level in the collecting cavity 421 reaches a certain level, the collecting component 42 can be removed, the liquid inside the collecting component 42 can be poured out, and then the collecting component 42 can be reinstalled for reuse. When the collecting component 42 is not installed, the anti-spraying liquid structure 40 needs to be removed after the receiving cavity 400 has collected a certain volume of liquid to drain the liquid that is about to overflow from the receiving cavity 400, in order to prevent the liquid in the receiving cavity 400 from overflowing and entering the collection container 10 through the pipeline. After the collection component 42 is installed, the collected liquid can be poured out through the detachable collection component 42, which increases the service life of the anti-spray liquid structure 40 and reduces the number of times the anti-spray liquid structure 40 needs to be disassembled and cleaned.

[0058] In this embodiment, one end of the collecting component 42 is detachably connected to the recycling component 41 through the mounting hole 402. This can be achieved by providing a threaded groove on the inner wall of the mounting hole 402 and a threaded structure at one end of the collecting component 42, with the threaded engagement of the two achieving the detachable connection. Alternatively, a locking part can be provided at one end of the collecting component 42, allowing the collecting component 42 and the mounting hole 402 to achieve a detachable connection through a snap-fit ​​engagement.

[0059] In one embodiment, please refer to Figure 3 The aerosol collection device also includes a second collection pipe 60 and at least two collection containers 10, with adjacent collection containers 10 connected by the second collection pipe 60.

[0060] The anti-spray liquid structure 40 is also provided on the second collection pipe 60 for recovering the liquid in the aerosol flowing through the second collection pipe 60.

[0061] In this embodiment, multiple collection containers 10 are provided to increase the absorption of aerosols. Adjacent collection containers 10 are connected by a second collection pipe 60, so that aerosols that are not absorbed in the previous collection container 10 can enter the next collection container 10 through the second collection pipe 60 and be further absorbed.

[0062] In this embodiment, one end of the second collection tube 60 is connected to the interior of the previous collection container 10, or it can be further detachably connected by the locking structure 50 described above. The other end of the second collection tube 60 extends into the test solution of the next collection container 10, and the above-mentioned gas outlet structure 221 can also be provided on this end to help aerosol absorption.

[0063] In one embodiment, the aerosol collection device further includes a negative pressure drive 70, which is connected to the inside of the collection container 10 and is used to generate a negative pressure inside the collection container 10 to drive the aerosol to be transported in the first collection pipeline 20 toward the collection container 10.

[0064] In this embodiment, the negative pressure drive 70 is used to create a negative pressure at one end of the aerosol collection device, so that the aerosol generated by the atomizing device 30 can enter the collection container 10 more quickly under negative pressure and be absorbed by the test solution.

[0065] In this embodiment, when there is only one collection container 10, the negative pressure drive 70 is directly connected to the interior of the collection container 10. When there are multiple collection containers 10 connected sequentially through the second collection pipe 60, the collection container 10 at one end is connected to the atomizing device 30, while the collection container 10 at the end away from the atomizing device 30 is connected to the negative pressure drive 70.

[0066] In one example, the negative pressure drive 70 is a negative pressure machine or a smoking machine.

[0067] In one embodiment, please refer to Figure 3 and Figure 4 One end of the first collection pipe 20 is provided with an air inlet structure 211, and an installation cavity 2115 is provided inside the air inlet structure 211. One end of the atomizing device 30 is fixed inside the installation cavity 2115 to realize the connection between the atomizing device 30 and the first pipe section 21.

[0068] The first collection pipe 20 is provided with an air outlet structure 221 at one end that extends into the collection container 10. The air outlet structure 221 is provided with multiple air outlet holes 222 so that the aerosol can enter the test solution through the multiple air outlet holes 222 and be absorbed.

[0069] And / or, the collection container 10 is provided with a sealing structure 11, and the first collection pipe 20 passes through the sealing structure 11 and extends into the test solution inside the collection container 10.

[0070] In this embodiment, the first pipe section 21 and the second pipe section 22 of the first collection pipe 20 are further optimized. The first pipe section 21 is provided with an air intake structure 211, which is used to fix, clamp or install the atomizing device 30, so that the aerosol generated by the atomizing device 30 can enter the installation cavity 2115 and then enter the recycling component 41.

[0071] In one example, please refer to Figure 4The air intake structure 211 includes a base plate 2110, a kit 2111, a top member 2112, at least one seal 2113, and a sealing ring 2114. The base plate 2110, kit 2111, and top member 2112 are connected in sequence. The seal 2113 is disposed within the kit 2111. The top member 2112 and the seal 2113 form a mounting cavity 2115, which communicates with the first pipeline section 21. One end of the atomizing device 30 passes through the base plate 2110 and the seal 2113, extends into the mounting cavity 2115, and is fixed by the seal 2113. The sealing ring 2114 is disposed at the connection between the top member 2112 and the kit 2111, and is used to improve the sealing performance of the top member 2112 within the kit 2111.

[0072] In this example, the atomizing device 30 can be a cigarette, which is placed in a container and extends into the mounting cavity 2115 through the bottle opening of the container and is fixed by the seal 2113.

[0073] In one embodiment, the atomizing device 30 can also be an existing electronic atomizer, the mouthpiece of which is directly connected to the first pipeline segment 21 via a pipe.

[0074] In this embodiment, the gas outlet structure 221 is a hollow spherical structure. The spherical structure is used to set a plurality of gas outlet holes 222 on its surface, increasing the gas outlet area and making the gas outlet holes 222 more fine and uniform, so that the gas entering the second pipeline section 22 can be easily absorbed by the test solution in the collection container 10 through the gas outlet holes 222 on the surface of the spherical structure.

[0075] In this embodiment, the sealing structure 11 is used to ensure the airtightness of the interior of the collection container 10 and prevent gas leakage. In one example, the sealing structure 11 may be a sealing plug disposed at the top opening of the collection container 10.

[0076] In one embodiment, the trapping container 10 is a trap. The test solution inside the trapping container 10 is an absorbent solution of 5% nitric acid.

[0077] In one embodiment, the anti-spray structure 40 is made of quartz glass.
