And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0030] In the related art, with the continuous development of the tobacco industry, although the types of tobacco products are rich and diverse. However, in today's tobacco market, traditional cigarettes and e-cigarettes are the most mainstream products in the tobacco industry. There are approximately 1.24 billion smokers globally. The aerosol exhaled during the process of smoking cigarettes or e-cigarettes contains solid small particles and is attached with tar, which affects the physical and mental health of others. The smoker inhales the aerosol through the inhalation channel. When the smoker exhales the aerosol, the aerosol first enters the aerosol elimination device through the exhalation channel to ensure that the exhaled aerosol can be concentrated and directionally processed, rather than being randomly diffused into the environment. To solve the above problems, generally, the exhaled gas is inhaled into the aerosol elimination device for filtration. However, the conventional aerosol elimination device has a poor effect on eliminating aerosol and has a large room for improvement.

[0031] In this application, by using the combination of the filter element 500 and the liquid matrix, the removal efficiency of particulate matter and harmful gases in the aerosol is greatly improved.

[0032] As Figure 1 and Figure 2 shown, to solve the above technical problems, in this embodiment, an aerosol elimination device is provided. The aerosol elimination device includes an aerosol elimination device body. The aerosol elimination device body has an exhalation channel 200, an inhalation channel 100, and a filter element 500. The filter element 500 is disposed in the exhalation channel 200. Among them, the filter element 500 adsorbs a liquid matrix that can filter the aerosol.

[0033] In this embodiment, the inside of the aerosol elimination device body is divided into an exhalation channel 200 and an inhalation channel 100, which can ensure the directional flow of the aerosol airflow. The inhalation channel 100 is used for the user to inhale the aerosol generated by the nebulizer, and the exhalation channel 200 is used to receive the aerosol exhaled by the user. Exemplarily, the aerosol elimination device body has a suction port 300, which serves as an interface when the user breathes the aerosol. It is connected to the aerosol elimination device body to ensure the interaction between the inhalation channel 100 and the exhalation channel 200 with the user. That is to say, when the air outlet of the nebulizer is connected to the inhalation channel 100, the user can inhale the aerosol generated by the nebulizer through the inhalation channel 100, and then directly exhale the aerosol into the exhalation channel 200 through the suction port 300 for filtration.

[0034] The filter element 500 is installed inside the exhalation channel 200. There is a liquid matrix attached to the filter element 500, which plays a key role in filtering and purifying the exhaled aerosol. Among them, during the inhalation stage: when the user inhales through the suction port 300, the aerosol airflow generated by the nebulizer passes through the inhalation channel 100 and the suction port 300 and enters the user's body. During the exhalation stage: when the user exhales, the aerosol airflow flows along the exhalation channel 200. At this time, the liquid matrix in the filter element 500 plays a role. Due to the distribution characteristics of the liquid matrix, it can effectively adsorb harmful substances in the exhaled aerosol, such as particulate matter, residual nicotine, etc., to achieve a purification effect.

[0035] Of course, the selection of the liquid matrix is crucial. It may contain adsorbents, catalysts or other chemical components, which can react with the harmful components in the aerosol or directly adsorb these components, thereby reducing the emission of harmful substances.

[0036] Exemplarily, the liquid matrix is propylene glycol (PG); of course, in other embodiments, it can also be water, sodium chloride aqueous solution, surfactant solution or other liquids with the ability to adsorb and filter particulate matter and harmful chemical substances in the aerosol, etc.

[0037] Exemplarily, since the filter element 500 has a porous adsorption structure, the adsorption and distribution of the liquid matrix can be completed by utilizing its own adsorption. Of course, during use, the liquid matrix is consumed, and the long-term use of the aerosol elimination device can be maintained by replenishing the liquid matrix. At the same time, the porous adsorption structure can filter out particulate matter in the aerosol, further enhancing the purification effect.

[0038] When using the aerosol elimination device provided by this application, a smoking enthusiast holds the suction port 300 in the mouth and inhales the aerosol through the inhalation channel 100, and then exhales the aerosol. When the smoking enthusiast exhales the aerosol, the aerosol first enters the aerosol elimination device through the exhalation channel 200, ensuring that the exhaled aerosol can be concentrated and directionally processed, rather than diffusing randomly into the environment. Among them, the filter element 500 installed in the exhalation channel 200 has a rich microporous structure. These micropores not only increase the surface area of the filter element 500, but also enable the aerosol to come into full contact with the surface of the filter element 500. A liquid matrix is pre-adsorbed on the filter element 500. When the aerosol passes through the filter element 500, the particulate matter (such as soot and tar particles) and harmful gases (such as carbon monoxide and nicotine vapor) in the aerosol will undergo physical or chemical reactions with the liquid matrix. The liquid matrix can absorb the moisture in the aerosol and dissolve some harmful substances; at the same time, the microporous structure can filter out the particulate matter in the aerosol, further enhancing the purification effect.

[0039] Obviously, by using the filter element 500 in combination with the liquid matrix, the removal efficiency of particulate matter and harmful gases in the aerosol is greatly improved, effectively solving the problem of poor purification effect of traditional aerosol elimination devices. After being filtered and purified by the filter element 500, the harmful components in the discharged aerosol are significantly reduced, reducing the impact on the surrounding people.

[0040] As Figure 2 shown, in some embodiments, the filter element 500 includes at least one filter layer. The at least one filter layer is disposed in the exhalation channel 200, and the at least one filter layer is sequentially arranged in the gas flow direction in the exhalation channel 200; among them, at least one of the at least one filter layer is set as a filter cotton layer 510, and the liquid matrix is attached and distributed in the filter cotton layer 510.

[0041] In these embodiments, the filter element 500 demonstrates a multi-level and high-efficiency aerosol filtration and purification strategy. Among them, taking the filter layer as a porous structure as an example, by setting at least one filter layer, the purification ability of the aerosol elimination device is improved. Among them, one filter layer is set as the filter cotton layer 510 with a porous structure to be able to adsorb and distribute the liquid matrix.

[0042] Among them, when the number of filter layers is multiple, the multiple filter layers are sequentially stacked in the gas flow direction.

[0043] Exemplarily, the filter cotton layers 510 are all set as sponge layers; of course, in other embodiments, the filter cotton layer 510 can also be set as a meltblown cloth layer, a nanofiber membrane layer, an electrospun layer, a plant fiber layer, etc.

[0044] In some embodiments, the mass of the liquid matrix attached to the filter cotton layer 510 accounts for 20%-40% of the mass of the filter cotton layer 510.

[0045] In these embodiments, the mass ratio between the filter cotton layer 510 and the liquid matrix adsorbed thereon is set within a specific range, that is, the mass ratio of the liquid matrix to the mass of the filter cotton layer 510 is between 20% and 40%. The mass ratio of the liquid matrix to the filter cotton layer 510 ensures that there is sufficient liquid matrix to effectively adsorb harmful substances in the aerosol or gas, while avoiding leakage or fluidity problems caused by oversaturation. The lower limit of 20% ensures that the basic adsorption requirements are met, while the upper limit of 50% prevents excessive liquid matrix from affecting the air permeability and mechanical strength of the porous cotton.

[0046] Obviously, the filter cotton layer 510 needs to maintain sufficient structural strength to withstand mechanical stresses during use, such as air flow pressure, vibration during operation, etc. The appropriate addition of the liquid matrix should not only ensure the adsorption effect but also avoid damage or deformation of the porous cotton structure caused by excessive weight.

[0047] This ratio also takes into account economy and the rationality of material use. Excessive liquid matrix will increase costs and the complexity of maintenance, while too little may not achieve the expected purification effect. By limiting the ratio, a balance can be found between cost-effectiveness and performance. For ease of understanding, the following exemplary embodiments are provided:

[0048] Embodiment 1: The mass ratio of the liquid matrix to the mass of the filter cotton layer 510 is 20%;

[0049] By smelling the aerosol at the outlet 212, it is measured that a small amount of aerosol odor is released in Embodiment 1 when the user takes 120 puffs. Therefore, the service life of the aerosol elimination device provided by Embodiment 1 is approximately 120 puffs.

[0050] Embodiment 2: The mass ratio of the liquid matrix to the mass of the filter cotton layer 510 is 30%;

[0051] By smelling the aerosol at the outlet 212, it is measured that a small amount of aerosol odor is released in Embodiment 2 when the user takes 180 puffs. Therefore, the service life of the aerosol elimination device provided by Embodiment 2 is approximately 180 puffs.

[0052] Embodiment 3: The mass ratio of the liquid matrix to the mass of the filter cotton layer 510 is 40%;

[0053] By smelling the aerosol at the outlet 212, it is measured that a small amount of aerosol odor is released in Embodiment 3 when the user takes 170 puffs. Therefore, the service life of the aerosol elimination device provided by Embodiment 3 is approximately 170 puffs.

[0054] Obviously, considering the three embodiments comprehensively, when the mass ratio of the liquid matrix to the mass of the filter cotton layer 510 is 20% to 40%, the effect is better, and it has a good effect of removing smoke and odor before reaching the service life.

[0055] In some embodiments, the number of filter layers is three, and the three filter layers are sequentially provided with a first filter cotton layer 511, a solid adsorbent layer 520, and a second filter cotton layer 512.

[0056] In these embodiments, it means that there are at least three independent filter levels in the device, which can gradually remove harmful substances of different sizes and properties in the aerosol, so as to achieve a deeper purification effect. Exemplarily, each filter layer is set to a different pore size.

[0057] In this embodiment, the number of filter layers is set to 3. Of course, in other embodiments, the number of filter layers can also be set to 4, 5, 6, 7, 8, etc., which are not specifically limited here.

[0058] For example, the first filter cotton layer 511 and the second filter cotton layer 512 at both ends are not only the portals for gas inlet and outlet, but also undertake the basic physical filtration function, such as capturing larger particles and preliminarily wetting the aerosol. Among them, the high porosity and good liquid retention ability of the first filter cotton layer 511 and the second filter cotton layer 512 enable it to effectively adsorb and carry the liquid matrix, and these liquid matrices can further adsorb harmful components in the aerosol or remove harmful substances through chemical reactions.

[0059] The solid adsorbent layer 520 is located between the first filter cotton layer 511 and the second filter cotton layer 512, and the solid adsorbent layer 520 is a key component in the purification process. Due to its unique adsorption performance, the solid adsorbent layer 520 can effectively adsorb gaseous harmful substances in the aerosol, such as nicotine, harmful gases, and odors. Its microporous structure provides a large surface area, which is beneficial to adsorb more harmful molecules and significantly improve the purification efficiency. And because the solid adsorbent layer 520 is located between the first filter cotton layer 511 and the second filter cotton layer 512, it is conducive to the first filter cotton layer 511 and the second filter cotton layer 512 to isolate the solid adsorbent layer 520 from the second inlet 211 and the second outlet 212 of the exhaust pipe 210 respectively. Only by filling the solid adsorbent between the first filter cotton layer 511 and the second filter cotton layer 512 can the solid adsorbent layer 520 be formed, without additional fixation, and it is convenient to replace the solid adsorbent layer 520 subsequently.

[0060] Exemplarily, both the first filter cotton layer 511 and the second filter cotton layer 512 are set as sponge layers; of course, in other embodiments, the first filter cotton layer 511 and the second filter cotton layer 512 can also be set as melt-blown cloth layers, nanofiber membrane layers, electrospun layers, plant fiber layers, and so on.

[0061] Exemplarily, the fixed adsorbent layer is an activated carbon layer; of course, in other embodiments, the fixed adsorbent layer can also be set as a charcoal layer, a bamboo charcoal layer, a biochemical filtration material layer, and so on.

[0062] Obviously, multiple filter layers are arranged in sequence in the gas flow direction, forming a step-by-step filtration process, enabling each filter layer to focus on removing pollutants of specific sizes or types. From coarse filtration to fine filtration, it progresses layer by layer, ensuring the efficient removal of most harmful components in the aerosol. At the same time, the liquid matrix attached to the first filter cotton layer 511 and the second filter cotton layer 512 can not only help physically adsorb particulate matter, but also further process harmful substances in the aerosol through dissolution, chemical reactions, etc., increasing the diversity and effectiveness of purification.

[0063] Therefore, by combining multiple purification mechanisms such as physical filtration, chemical adsorption, and possible chemical reactions, it provides an efficient and multi-level solution for aerosol elimination, which is particularly suitable for improving the comprehensive performance of exhaled aerosol treatment and is beneficial to protecting the air quality of users and the surrounding environment.

[0064] In some embodiments, the pore diameters of both the first filter cotton layer 511 and the second filter cotton layer 512 are smaller than the pore diameter of the solid adsorbent layer 520.

[0065] In these embodiments, by setting a multi-layer structure with different pore diameters, hierarchical filtration of particles with different particle sizes in the inhaled aerosol is achieved. The small pore diameter of the first filter cotton layer 511 can first capture larger particulate matter and some liquid droplets, playing a role of pre-filtration, reducing the burden on the subsequent solid adsorbent layer 520, extending its service life, and improving the overall purification efficiency. The second filter cotton layer 512 can achieve secondary filtration and play a role in supporting and fixing the solid adsorbent layer 520.

[0066] The smaller pore diameters in the first filter cotton layer 511 and the second filter cotton layer 512 can increase the contact time between the aerosol and the first filter cotton layer 511 and the second filter cotton layer, helping to improve the adsorption efficiency of the liquid matrix for gaseous harmful substances in the aerosol and maintaining the adhesion of the liquid matrix on the filter cotton layer 510. At the same time, it may also slow down the flow rate, making the airflow more uniform and stable, which is beneficial to improving the efficiency of the entire purification process.

[0067] The first filter cotton layer 511, as a pre-filter, can prevent large particulate matter from directly hitting and clogging the larger pores of the solid adsorbent layer 520, protect expensive or highly efficient adsorbents from physical damage, and maintain their long-term adsorption performance.

[0068] Obviously, this hierarchical filtration scheme enables layers of different materials and pore sizes to work together, not only effectively removing particulate matter, but also more finely removing pollutants in the aerosol through the subsequent solid adsorbent layer 520, thereby achieving more comprehensive air purification.

[0069] In some embodiments, the aerosol elimination device body further includes a suction port 300, and the suction port 300 is respectively communicated with the inhalation channel 100 and the exhalation channel 200. Among them, the inhalation channel 100 is configured to conduct unidirectionally in the direction towards the suction port 300, and the exhalation channel 200 is configured to conduct unidirectionally in the direction away from the suction port 300.

[0070] The suction port 300, as the interface when the user breathes the aerosol, is connected to the aerosol elimination device body to ensure the interaction between the inhalation air path 100 and the exhalation air path 200 and the user. That is to say, when the outlet of the atomizer is communicated with the inhalation air path 100, the user can suck the aerosol generated by the atomizer through the inhalation air path 100, and then directly exhale the aerosol into the exhalation air path 200 through the suction port 300 for filtration.

[0071] Among them, the unidirectional flow of the inhalation air path 100 and the exhalation air path 200 has the following functions: 1. During the inhalation stage, only the aerosol is inhaled along the inhalation air path 100, avoiding the airflow in the exhalation air path 200 from entering the mouth of the suctioner; 2. During the exhalation stage, only the aerosol exhaled from the mouth of the suctioner is discharged along the exhalation air path 200, and the aerosol does not enter the inhalation air path 100.

[0072] In some embodiments, the aerosol elimination device body includes an intake pipe 110 and an intake check valve 120. The intake pipe 110 and the intake check valve 120 are connected in series. The intake pipe 110 and the intake check valve 120 connected in series form an inhalation channel 100. The intake pipe 110 has a first inlet and a first outlet, and the first outlet is communicated with the suction port 300. The intake check valve 120 has a conduction direction, and the conduction direction of the intake check valve 120 is from the first inlet to the first outlet.

[0073] In these embodiments, the connection of the intake pipe 110 to the suction port 300. The intake pipe 110, as a part of the inhalation channel 100, the main function of the intake pipe 110 is to guide the aerosol inhaled by the smoker through, and the intake pipe 110 is directly connected to the suction port 300. This ensures that when the smoker inhales, the aerosol can smoothly enter the mouth of the suctioner.

[0074] The intake one-way valve 120 is installed on the connection path between the intake pipe 110 and the suction port 300. The characteristic of the intake one-way valve 120 is that it only allows air flow to pass through in one direction, that is, from the intake pipe 110 towards the suction port 300, while preventing reverse flow. The purpose of this structure is to ensure that the air flow during inhalation is directional, avoiding the inflow of exhaled aerosol into the inhalation channel 100.

[0075] The conducting direction of the intake one-way valve 120 is clearly from the intake pipe 110 to the suction port 300, which means that it is structurally designed with specific mechanisms, such as valve flaps, spring-loaded valves, etc. When the air flow moves in the conducting direction, the intake one-way valve 120 opens; while when the air flow attempts to flow in the reverse direction, it will be effectively blocked by the intake one-way valve 120.

[0076] Obviously, the combination of the intake pipe 110 and the intake one-way valve 120 together constitutes the inhalation channel 100, which is the gas input channel in the entire aerosol elimination device and is crucial for ensuring that smokers can smoothly inhale the aerosol.

[0077] In some embodiments, the aerosol elimination device body further includes an exhaust pipe 210 and an exhaust one-way valve 230. The exhaust pipe 210 and the exhaust one-way valve 230 are connected in series. The exhaust pipe 210 and the exhaust one-way valve 230 connected in series form an exhalation channel 200. The exhaust pipe 210 has a second inlet 211 and a second outlet 212. The second inlet 211 is in communication with the suction port 300. The exhaust one-way valve 230 has a conducting direction, and the conducting direction of the exhaust one-way valve 230 is from the second inlet 211 to the second outlet 212, and the filter element 500 is installed inside the exhaust pipe 210.

[0078] In these embodiments, the exhaust pipe 210, the exhaust one-way valve 230, and the series connection with the suction port 300 are integrated in the aerosol elimination device body. Such a layout ensures that the exhaled aerosol starts from the suction port 300, passes through the exhaust one-way valve 230, and finally reaches the exhaust pipe 210, forming a closed and directional exhalation channel 200.

[0079] The exhaust one-way valve 230 is configured to only allow the aerosol to flow from the direction of the suction port 300 to the exhaust pipe 210, preventing the reverse flow of air. This can effectively avoid the backflow of the filtered aerosol or outside air into the mouth of the smoker, and can also prevent the user from inhaling the gas in the exhalation channel 200 during inhalation.

[0080] Among them, the filter element 500 is placed inside the exhaust pipe 210. The porous structure of the filter element 500 not only increases the contact area with the exhaled aerosol, but also effectively captures and processes harmful components in the aerosol, such as particulate matter and harmful gases, through the liquid matrix adsorbed or distributed thereon, such as water or other chemisorbents, so as to achieve the purpose of purifying the aerosol.

[0081] Obviously, the exhalation channel 200 jointly formed by the exhaust pipe 210 and the exhaust one-way valve 230 not only ensures the smooth discharge of the exhaled aerosol, but also significantly improves the aerosol treatment effect through the purification of the filter element 500, reducing the adverse effects on the environment and surrounding personnel.

[0082] In some embodiments, the aerosol elimination device body further includes a hose 400, and one end of the hose 400 is communicated with the first inlet of the intake pipe 110.

[0083] In this embodiment, the hose 400 realizes the quick connection and disassembly between the aerosol elimination device and the nebulizer. This modular design facilitates users to replace or upgrade components according to needs, and also simplifies the subsequent maintenance and cleaning processes.

[0084] The use of the hose 400 provides a high degree of flexibility for the aerosol elimination device, capable of adapting to the installation requirements at different angles and distances. When the device is connected to the air outlet of the nebulizer, even in the case of limited space or the need for bending and detouring, it can be easily docked, improving the convenience and general applicability of use.

[0085] Exemplarily, the hose 400 is equipped with a quick plug-in or snap-type interface, enabling users to easily connect or disconnect the hose 400 with the aerosol elimination device body and the air outlet without complex tools, facilitating daily maintenance and cleaning.

[0086] Exemplarily, the nebulizer has a mouthpiece, and the hose 400 is in interference fit with the mouthpiece away from the first inlet. And they are connected in a plug-and-play manner, facilitating subsequent disassembly and assembly.

[0087] Alternatively, in other embodiments, the nebulizer has an atomization channel, and one end of the hose 400 away from the first inlet is inserted into the air outlet of the atomization channel, and they are in interference fit.

[0088] In addition, as a flexible connector, the hose 400 can ensure good sealing performance by using elastic deformation. Obviously, to ensure good sealing performance and prevent air leakage, high-quality sealing materials and reasonable interface designs can be adopted to ensure the airtightness of the connection part of the hose 400.

[0089] Exemplarily, the hose 400 is provided as a rubber hose 400; of course, in other embodiments, the hose 400 may also be provided as a plastic hose, a silicone hose, a nylon hose, etc., which are not specifically defined herein.

[0090] In some embodiments, the aerosol elimination device body further includes an adapter pipe 220. The intake pipe 110 passes through the exhaust pipe 210. The exhaust pipe 210 has a plurality of second inlets 211 and a plurality of the second outlets 212. The plurality of second inlets 211 are arranged at intervals along the circumferential direction of the intake pipe 110, and the plurality of second outlets 212 are arranged at intervals along the circumferential direction of the intake pipe 110. The second inlet 211 is communicated with the suction port 300 through the adapter pipe 220.

[0091] In these embodiments, the adapter pipe 220, as a connecting component, is configured to connect the suction port 300 and the second inlet end of the exhaust pipe 210. The adapter pipe 220 can be of a fixed angle, bendable or telescopic to adapt to different types of suction ports 300.

[0092] The exhaust pipe 210 has an inlet end and an outlet end arranged oppositely. The second inlet end is provided with a plurality of second inlets 211. This structure can disperse the exhaled aerosol more evenly, avoid excessive local pressure, so that the aerosol can be preliminarily dispersed before entering the purification process, which is beneficial to the efficient progress of the subsequent purification and filtration steps.

[0093] Similarly, the outlet end of the exhaust pipe 210 is also provided with a plurality of second outlets 212, which helps the purified gas to be discharged into the environment more evenly and quickly, reduces the air pressure accumulation, and may also help to reduce the emission noise and improve the use experience.

[0094] Obviously, through the combined configuration of the adapter pipe 220, the plurality of second inlets 211 and the plurality of second outlets 212, not only the smoothness of the aerosol flowing inside the device is improved, but also the directionality and uniformity of the air flow are effectively controlled, ensuring that the aerosol elimination device can efficiently and quickly process the exhaled aerosol, while reducing the internal pressure loss and maintaining the low-resistance operation of the device.

[0095] In addition, the intake pipe 110 passes through the inside of the exhaust pipe 210. This structural layout makes full use of the space, makes the aerosol elimination device as a whole more compact, and improves the portability of the aerosol elimination device. And, the intake air cools the exhaust air, or uses the heat energy of the exhaust air to preheat the intake air.

[0096] Wherein, the suction port is communicated with the second inlet 211 through the adapter pipe 220. This increases the intake area, enables the aerosol to enter the exhaust pipe 210 evenly and efficiently from multiple directions, helps to improve the uniformity and stability of the air flow, reduces the resistance, and improves the smoothness of the exhalation process.

[0097] Moreover, the outlet end of the exhaust pipe 210 also has a plurality of second outlets 212 spaced circumferentially. This structure can ensure that after the gas contacts the filter element 500 inside the exhaust pipe 210, it can be discharged evenly and quickly.
