[0002] In the prior art, an aerosol generating device can atomize an atomizing medium to form an aerosol through a power supply structure for inhalation. However, the atomizing medium, condensate, and overflowing aerosol easily leak out from the air inlet of the aerosol generating device and contaminate the power supply structure, causing the power supply structure to malfunction or fail. Utility Model Content

[0003] The embodiment of the present application provides an aerosol generating device, and is at least used to improve the problem of atomized medium leaking and contaminating the power supply structure.

[0004] The aerosol generating device of the embodiment of the present application includes an atomizer, a power supply structure and an adsorbent, wherein the atomizer includes a peripheral surface and an end surface connected to the peripheral surface, the end surface is provided with an air inlet, the atomizer is connected to the power supply structure at the end surface, the adsorbent is provided on the end surface, the adsorbent is located outside the atomizer and distributed on the edge of the air inlet.

[0005] The aerosol generating device of the embodiment of the present application arranges the adsorbent at the edge of the air inlet where the atomizer and the power supply structure are connected, so that the adsorbent can timely adsorb the atomized medium, condensate, etc. leaking from the air inlet, thereby preventing the atomized medium, condensate, etc. from contaminating the power supply structure and ensuring the normal operation of the electrical components of the power supply structure. In addition, the adsorbent can also adsorb and clean the existing stains on the power supply structure.

[0006] In some embodiments, a groove is formed on the end surface, and the adsorption element is disposed in the groove.

[0007] In this way, by arranging the adsorption member in the groove, it is convenient to install and fix the adsorption member, which is conducive to accommodating the adsorbed oil stains.

[0008] In some embodiments, the groove is in communication with the air inlet.

[0009] In this way, by forming a groove connected to the air inlet on the side around the air inlet, the groove can guide the atomized medium, condensate, etc. overflowing from the air inlet to flow and accumulate in the groove, and the adsorbent can directly contact the oil leaked from the air inlet, thereby improving the adsorption effect and efficiency of the adsorbent.

[0010] In some embodiments, the air inlet is disposed at the center of the end surface, and the groove extends from the air inlet to the edge of the end surface.

[0011] In this way, the groove extends from the center of the end face to the edge of the end face, and the area of ​​the groove accounts for a higher proportion of the overall area of ​​the end face, thereby maximizing the area of ​​the groove and increasing the adsorption area of ​​the adsorbent.

[0012] In some embodiments, there are multiple grooves, and an adsorption member is disposed in each groove.

[0013] In this way, by providing a plurality of grooves, the number of adsorbents is increased, the area that the adsorbents can cover is expanded, and the adsorption effect is improved.

[0014] In some embodiments, the surface of the adsorbent is flush with the end surface, or the adsorbent protrudes from the end surface.

[0015] In this way, the surface of the adsorbent is flush with the end surface or protrudes from the end surface, so that the thickness of the adsorbent is not less than the groove depth of the groove, thereby increasing the oil and dirt capacity that the adsorbent can adsorb.

[0016] In some embodiments, there are multiple adsorbents, and the multiple adsorbents are arranged around the air inlet.

[0017] In this way, by arranging a plurality of adsorbents around the air inlet, the adsorbents can fully absorb the oil and dirt leaked from different positions of the edge of the air inlet.

[0018] In some embodiments, the number of the adsorbent is one piece, and the adsorbent forms an avoidance hole, which corresponds to and is connected to the air inlet.

[0019] In this way, the number of the adsorbent is one piece, which can simplify the overall structure of the aerosol generating device and facilitate assembly. The avoidance hole formed on the adsorbent can prevent the adsorbent from covering the air inlet, thereby ensuring smooth inhalation.

[0020] In some embodiments, the aerosol generating device comprises an adhesive layer, and the adsorbent is bonded to the atomizer via the adhesive layer.

[0021] In this way, the adsorbent is adhered to the atomizer through the adhesive layer, reducing the probability of the adsorbent falling off.

[0022] In some embodiments, the absorbent is oil-absorbing cotton.

[0023] In this way, the oil-absorbing cotton is used as the adsorption member, which has a better adsorption effect on oil and liquid, and has a low manufacturing cost and strong feasibility.

[0039] See also Figure 1 In the present application, the aerosol generating device 100 is a structure that can generate aerosol by acting on the atomizing medium through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound or mechanical vibration. The atomizing medium is a substance that can produce an aerosol after being processed and heated. The form of the atomizing medium can be fully solid or semi-solid, or it can be liquid. For example, the solid atomizing medium can be a plant flower, stem or leaf product prepared by rolling, slurrying, die casting, extrusion and other process methods. For another example, the liquid atomizing medium can include a liquid composition based on plant extracts and / or various flavoring agents.

[0040] In the following description, the atomizing medium may refer to a liquid atomizing medium. The liquid atomizing medium may include at least one solvent of propylene glycol and glycerol, and may also include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleic acid. In some embodiments, the atomizing medium may include nicotine, moisture and / or flavoring substances. In other embodiments, the atomizing medium may further include a variety of added substances such as cinnamon and capsaicin. The atomizing medium may include not only liquid substances with high fluidity, but also substances in the form of gel or solid powder. The components of the atomizing medium may have a variety of options depending on the embodiment, and the composition ratio may also vary depending on the embodiment. The scope of the embodiments of the present application is not limited to the examples listed above.

[0041] The atomizing medium is heated and atomized to form an aerosol, which may be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed vapor. The aerosol may contain volatile compounds. The user may inhale the aerosol into the oral cavity, nasal cavity or lungs through the mouth or nose, and the aerosol inhaled into the user's respiratory system may be used for a variety of purposes such as food, medicine, health care, and entertainment.

[0042] See also Figure 2-Figure 4 , Figure 21 is a schematic diagram of the structure of the aerosol generating device 100 according to the embodiment of the present application without the housing 50. Figure 4 1 is a schematic diagram of the structure decomposition of the aerosol generating device 100 of another embodiment without the housing 50. The aerosol generating device 100 of the embodiment of the present application comprises an atomizer 10, a power supply structure 20 and an adsorbent 30, wherein the atomizer 10 comprises a peripheral surface 11 and an end surface 12 connected to the peripheral surface 11, the end surface 12 is provided with an air inlet 101, the atomizer 10 is connected to the power supply structure 20 at the end surface 12, the adsorbent 30 is provided on the end surface 12, and the adsorbent 30 is located outside the atomizer 10 and distributed at the edge of the air inlet 101.

[0043] The aerosol generating device 100 of the embodiment of the present application sets the adsorbent 30 at the edge of the air inlet 101 where the atomizer 10 and the power supply structure 20 are connected, so that the adsorbent 30 can timely adsorb the atomized medium, condensate, etc. leaking from the air inlet 101, thereby preventing the atomized medium, condensate, etc. from contaminating the power supply structure 20 and ensuring the normal operation of the electrical components of the power supply structure 20. In addition, the adsorbent 30 can also adsorb and clean the existing stains on the power supply structure 20.

[0044] Specifically, the aerosol generating device 100 may be a rod-shaped structure similar to a cigarette, or may be a flat structure, a spherical structure, or a spherical structure. Figure 1 The rod-shaped structure shown is used as an example for explanation.

[0045] The aerosol generating device 100 may include a mouthpiece 40 and a housing 50. The mouthpiece 40 may be mounted on the atomizer 10 for contacting the mouth or nose of a user to inhale the aerosol. The housing 50 is disposed outside the power supply structure 20 to protect the power supply structure 20 and prevent electrical components from being exposed. When the atomizer 10 and the power supply structure 20 are assembled together, the housing may cover a portion of the atomizer 10.

[0046] The atomizer 10 is used to carry the atomized medium. The atomizer 10 is formed with a receiving chamber 102, and the atomized medium can be received in the receiving chamber 102. After being used for a period of time, the atomizer 10 can be removed from the power supply structure 20 and replaced with a new atomizer 10, or the atomized medium can be replenished or the aerosol generating device 100 can be cleaned. The air inlet 101 can be connected to the receiving chamber 102 and the suction nozzle 40. When the user inhales the aerosol, the airflow passes through the air inlet 101 into the receiving chamber 102 and takes away the aerosol.

[0047] The power supply structure 20 is used to provide energy for the atomizer 10 to atomize the atomizing medium to generate an aerosol. When powered on, the power supply structure 20 can atomize the atomizing medium to generate an aerosol by one or more of resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound or mechanical vibration. The power supply structure 20 may include components such as batteries, spring needles, microphones, and circuit boards. Exemplarily, the atomizer 10 may be provided with a circuit with a resistance wire, and when the atomizer 10 is connected to the power supply structure 20, the resistance wire is connected to the power supply circuit of the power supply structure 20 to generate heat, thereby heating the atomizing medium to form an aerosol.

[0048] The aerosol formed by the atomizing medium cannot be completely sucked out, and a small amount of aerosol remains in the atomizer 10. The aerosol can cool and condense to form small water droplets, which accumulate to form condensate. The components of the condensate formed by incomplete suction include water and a small amount of atomizing medium. The condensate remains in the atomizer 10 and easily flows along the wall of the container under the action of gravity, flows out from the air inlet 101, and is contaminated on the outer wall of the atomizer 10 and the power supply structure 20, forming oil stains.

[0049] The adsorbent 30 is used to adsorb the oil leaked from the air inlet 101. The adsorbent 30 has good adsorption properties for the oil leaked from the air inlet 101. The oil leaked from the air inlet 101 may include water, condensate, atomized medium and a small amount of aerosol. The oil flows out from the air inlet 101, and the flow resistance is greatly increased after being adsorbed by the adsorbent 30, so that it stagnates in the adsorbent 30 and is not easily contaminated on the power supply structure 20, thereby avoiding failure of electrical components and increasing the service life of the power supply structure 20. The service life of the atomizer 10 is shorter than that of the power supply structure 20, and the replacement frequency is higher. The adsorbent 30 can be replaced together with the atomizer 10, so that the adsorbent 30 can fully adsorb the leaked oil within the service life of the atomizer 10.

[0050] In some embodiments, condensate or condensed aerosol remains in the power supply structure 20. After replacing the atomizer 10 and the adsorbent 30, part of the oil accumulated inside the atomization power supply structure 20 can be absorbed by the adsorbent 30, thereby further improving the service life of the power supply structure 20.

[0051] In some embodiments, the aerosol generating device 100 is columnar, and the atomizer 10 and the power supply structure 20 may both be columnar. The nozzle 40 may be disposed at one end of the aerosol generating device 100 in the height direction and installed on the atomizer 10. In the following description, the direction in which the nozzle 40 points to the end face 12 is the direction from top to bottom, that is, the vertical direction. The atomizer 10 and the power supply structure 20 may be stacked up and down, and the end face 12 of the atomizer 10 is located at the bottom of the atomizer 10. A joint may be disposed at the end face 12 to electrically connect with the power supply structure 20. The atomizer 10 and the power supply structure 20 are stacked up and down to make the structure compact while ensuring the insulation strength of the power supply structure 20. The circumferential surface 11 of the atomizer 10 refers to the outer wall surface of the atomizer 10 in the stacking direction of the atomizer 10 and the power supply structure 20. Figure 6 In the illustrated embodiment, the peripheral surface 11 of the atomizer 10 is an outer wall surface of the atomizer 10 extending from top to bottom.

[0052] The present application does not limit the cross-sectional shapes of the atomizer 10 and the power supply structure 20 and the shape of the end face 12. The cross-sectional shapes of the atomizer 10 and the power supply structure 20 and the shape of the end face 12 can be circular, elliptical, triangular, quadrilateral, racetrack or other special shapes containing straight edges and curved edges. The air inlet 101 can be set at any position of the end face 12. To facilitate the flow of air into the atomizer 10, the air inlet 101 can be set at a position directly opposite to the accommodating cavity 102 in the vertical direction, for example, the air inlet 101 is at the center of the end face 12.

[0053] See also Figure 4-Figure 6 In some embodiments, a groove 121 is formed on the end surface 12 , and the adsorption member 30 is disposed in the groove 121 .

[0054] In this way, by arranging the adsorption member 30 in the groove 121, it is convenient to install and fix the adsorption member 30, which is beneficial to contain the adsorbed oil stains.

[0055] Specifically, in Figure 6 In the illustrated embodiment, the end face 12 is circular. Part of the wall surface of the end face 12 is closer to the suction nozzle 40 than the position where the end face 12 is connected to the peripheral surface 11, thereby forming a groove 121. The present application does not limit the contour shape of the groove 121, and the groove 121 can be circular, elliptical, square, rectangular, diamond, polygonal or any other shape. The shape of the adsorbent 30 is consistent with the groove 121 to improve the volume utilization of the groove 121 and increase the capacity for adsorbing oil stains. The size of the adsorbent 30 should be slightly smaller than the groove 121 so that the adsorbent 30 can be installed in the groove 121.

[0056] See also Figure 5 and Figure 6 , Figure 51 is a schematic diagram of the structure of the aerosol generating device 100 without the housing 50 according to the embodiment of the present application. In some embodiments, the groove 121 is connected to the air inlet 101 .

[0057] In this way, by forming a groove 121 connected to the air inlet 101 on the side around the air inlet 101, the groove 121 can guide the atomized medium, condensate, etc. overflowing from the air inlet 101 to flow and accumulate in the groove 121, so that the adsorbent 30 can directly contact the oil leaked from the air inlet 101, thereby improving the adsorption effect and efficiency of the adsorbent 30.

[0058] Specifically, the groove 121 is connected to the air inlet 101, and the adsorbent 30 is arranged in the groove 121. The condensate, atomized medium, aerosol and other oils and dirts flowing out of the air inlet 101 flow out along the wall surface of the air inlet 101. The adsorbent 30 can contact the edge where the inner wall surface of the air inlet 101 and the end surface 12 meet, so that the adsorbent 30 can quickly adsorb the oils and dirts flowing out through the edge of the air inlet 101. After being adsorbed, the oils and dirts are contained in the groove 121 with the adsorbent 30 and no longer flow.

[0059] See also Figure 6 In some embodiments, the air inlet 101 is disposed at the center of the end surface 12 , and the groove 121 extends from the air inlet 101 to the edge of the end surface 12 .

[0060] Thus, the groove 121 extends from the center of the end surface 12 to the edge of the end surface 12 , and the area of ​​the groove 121 accounts for a high proportion of the overall area of ​​the end surface 12 , thereby maximizing the area of ​​the groove 121 and increasing the adsorption area of ​​the adsorbent 30 .

[0061] Specifically, as described above, the air inlet 101 is arranged at the center of the end face 12 for easy air intake. The edge of the end face 12 refers to the connection between the end face 12 and the peripheral surface 11. The groove 121 is connected to the air inlet 101 at the edge of the air inlet 101 and extends to the connection between the end face 12 and the peripheral surface 11. The adsorbent 30 has the same shape as the groove 121. The adsorbent 30 extends from the junction of the wall surface of the air inlet 101 and the bottom surface of the groove 121 and covers the entire bottom surface of the groove 121. Such a design can also prevent the adsorbent 30 from blocking the air inlet 101, resulting in increased suction resistance and inconvenience in suction.

[0062] Exemplarily, the end face 12 is circular, the air inlet 101 is arranged at the center of the end face 12 , and the air inlet 101 may also be circular. The groove 121 may be fan-shaped, and the fan-shaped groove 121 may be concentric with the air inlet 101 and the end face 12 .

[0063] In other embodiments, the end face 12 is circular, the air inlet 101 is arranged at the center of the end face 12, the groove 121 is annular surrounding the air inlet 101, the inner periphery of the annular groove 121 is close to the edge of the air inlet 101, and the outer periphery is close to the edge of the end face 12.

[0064] See also Figure 4 and Figure 6 In some embodiments, there are multiple grooves 121 , and an adsorption member 30 is disposed in each groove 121 .

[0065] In this way, by providing a plurality of grooves 121 , the number of adsorbents 30 is increased, the area that can be covered by the adsorbents 30 is expanded, and the adsorption effect is improved.

[0066] Specifically, the number of grooves 121 is multiple, which means that the number of grooves 121 can be two, three, four, or more than four. Multiple grooves 121 can be arranged along the circumference of the end surface 12, surrounding the side of the air inlet 101. Each groove 121 is connected to the air inlet 101, and the grooves 121 can be considered to be connected to each other.

[0067] The shapes of the plurality of grooves 121 may be the same or different. To improve the space utilization rate at the end surface 12, the plurality of grooves 121 may all be fan-shaped with the center of the end surface 12 as the center of the circle. The plurality of fan-shaped grooves 121 may be arranged along the circumference of the end surface 12.

[0068] Exemplarily, there are two grooves 121 , and both of the two grooves 121 may be fan-shaped. The two grooves 121 may be distributed on both sides of the air inlet 101 along the radial direction of the end surface 12 .

[0069] See also Figure 6 In some embodiments, the surface of the adsorption member 30 is flush with the end surface 12 , or the adsorption member 30 protrudes from the end surface 12 .

[0070] In this way, the surface of the adsorbent 30 is flush with the end surface 12 or protrudes from the end surface 12 , so that the thickness of the adsorbent 30 is not less than the depth of the groove 121 , thereby increasing the oil capacity that the adsorbent 30 can adsorb.

[0071] Specifically, the surface of the adsorbent 30 facing the atomizer 10 is disposed in the groove 121 and can be fitted with the bottom surface of the groove 121. The surface of the adsorbent 30 facing the power supply structure 20 can be flush with the end surface 12, and the thickness of the adsorbent 30 is close to the depth of the groove 121. The surface of the adsorbent 30 facing the power supply structure 20 can also extend a certain height toward the power supply structure 20, so that the adsorbent 30 protrudes from the end surface 12, further increasing the thickness of the adsorbent 30.

[0072] See also Figure 4In some embodiments, the number of adsorbents 30 is multiple, and the multiple adsorbents 30 are arranged around the air inlet 101 .

[0073] In this way, by arranging a plurality of adsorbents 30 around the air inlet 101 , the adsorbents 30 can fully absorb the oil leaked from different positions of the edge of the air inlet 101 .

[0074] Specifically, the number of adsorbents 30 may be two, three, four or more than four. Multiple adsorbents 30 are arranged in the groove 121, and each groove 121 can only accommodate one adsorbent 30. The number of grooves 121 and adsorbents 30 is the same and one-to-one. The shapes and sizes of the adsorbents 30 may be the same, or they may be different in shape and size. To facilitate standardized production, multiple adsorbents 30 may be fans of equal shape and size. The adsorbents 30 are embedded in the fan-shaped grooves 121, surrounded by the air inlet 101 as the center and arranged at intervals.

[0075] Exemplarily, the number of the adsorbents 30 is two, and the two adsorbents 30 are respectively disposed in the grooves 121 on both sides of the air inlet 101. The two adsorbents 30 are distributed on both sides of the air inlet 101.

[0076] See also Figure 5 In some embodiments, the number of the adsorption member 30 is one piece, and the adsorption member 30 forms an avoidance hole 301 , which corresponds to and is connected to the air inlet 101 .

[0077] In this way, only one adsorption member 30 is provided to simplify the production process and facilitate assembly. The avoidance hole 301 formed on the adsorption member 30 can prevent the adsorption member 30 from covering the air inlet 101, thereby ensuring smooth suction.

[0078] Specifically, the adsorbent 30 covers the end face 12 and forms an avoidance hole 301 opposite to the air inlet 101. Exemplarily, the end face 12 is circular, the air inlet 101 is located at the center of the end face 12, the groove 121 is annular and concentric with the end face 12, the inner periphery of the groove 121 is connected to the edge of the air inlet 101, and the adsorbent 30 has the same shape as the groove 121. The adsorbent 30 is embedded in the groove 121 and surrounds the air inlet 101.

[0079] The bottom surface of the adsorbent 30 is in close contact with the bottom surface of the groove 121 on the end surface 12, and the avoidance hole 301 and the air inlet 101 can be directly opposite in the direction in which the adsorbent 30 and the end surface 12 are stacked, and the diameter of the avoidance hole 301 is slightly larger than or equal to the diameter of the air inlet 101. When the user inhales the aerosol, the bottom airflow can enter the accommodating chamber 102 through the avoidance hole 301 and the air inlet 101.

[0080] See also Figure 2In some embodiments, the aerosol generating device 100 includes an adhesive layer 31 , and the adsorbent 30 is bonded to the atomizer 10 via the adhesive layer 31 .

[0081] In this way, the adsorbent 30 is adhered to the atomizer 10 through the adhesive layer 31, thereby reducing the probability of the adsorbent 30 falling off.

[0082] Specifically, the adhesive layer 31 can be made of a sticky material, such as glue, solid glue, etc. The adhesive layer 31 can also be a tape or adhesive plaster with bidirectional stickiness. For example, the adhesive layer 31 can be a double-sided adhesive tape. The side of the adsorbent 30 facing the atomizer 10 is covered with the double-sided adhesive tape, and a certain pressure is applied to the side of the adsorbent 30 away from the atomizer 10 to make the adsorbent 30 fit the atomizer 10. The adhesive layer 31 can also be set on the inner wall surface of the groove 121, and the adsorbent 30 is installed in the groove 121 and adhered to the atomizer 10 through the adhesive layer 31. The position of the adsorbent 30 can also be fixed by the adhesive layer 31 to prevent the adsorbent 30 from shifting due to oil lubrication after absorbing oil.

[0083] In some embodiments, the adsorbent 30 is oil-absorbing cotton 32 .

[0084] In this way, the oil-absorbing cotton 32 is used as the adsorption member 30, which has a better adsorption effect on oil and liquid, and has a low manufacturing cost and strong feasibility.

[0085] Specifically, the oil-absorbing cotton 32 can be composited with non-woven fabrics, melt-blown fabrics, anti-permeability membrane layers, etc., and can quickly absorb condensate containing water and oil, and it is not easy for the oil to overflow after absorbing the oil.

[0086] In other embodiments, the absorbent 30 may also be oil-absorbing paper, oil-absorbing felt, cotton plug, soft cloth, silica gel, aluminum foil, etc.

[0087] The aerosol generating device 100 of the embodiment of the present application attaches oil-absorbing cotton 32 to the end surface 12 where the atomizer 10 is connected to the power supply structure 20 to absorb condensed liquid, atomized medium and other oil stains leaked from the air inlet 101, prevents the leaked liquid from dripping onto the power supply structure 20 and causing electrical device failure, thereby improving the reliability and service life of the power supply structure 20.
