However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0033] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0035] In the case where the aerosol generating device includes a cylindrical heating element, an atomizing chamber may be provided in the center of the cylindrical heating element. At this time, the atomizing chamber may correspond to and be connected to both the first airway (upper airway) and the second airway (lower airway), the flow path of the aerosol is short, and the user can quickly inhale the aerosol. However, when the user inhales, the aerosol generating matrix near the heating element easily leaks into the first airway and / or the second airway, causing the first airway and / or the second airway to be blocked, and the aerosol cannot flow out of the aerosol generating device through the airway. In order to solve this problem, the embodiment of the present application provides a nebulizer 100 and an aerosol generating device 1000 ( Figure 1 shown).

[0036] See also Figure 1 and Figure 2 The aerosol generating device 1000 of the embodiment of the present application includes a battery assembly 300 and an atomizer 100 , and the atomizer 100 is electrically connected to the battery assembly 300 .

[0037] The aerosol generating device 1000 is a structure capable of generating an aerosol by heating an aerosol generating substrate. Aerosols can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating substrate is a product that has been processed and heated to generate an aerosol. The aerosol generating substrate may be in liquid, fully solid, or semi-solid form. When the aerosol generating substrate is liquid, the liquid aerosol generating substrate is a mixed liquid containing substances such as nicotine and nicotine dissolved therein, and its solutes are common organic and / or inorganic solutes such as propylene glycol, vegetable glycerin, and pure water. When the aerosol generating substrate is fully solid, the aerosol generating substrate may be prepared using processes such as rolling, slurrying, die casting, and extrusion. In the present application, the aerosol generating substrate may be a high-viscosity tobacco oil (e.g., sesame oil), which is capable of generating an aerosol when heated.

[0038] The battery assembly 300 is used to power the atomizer 100. The atomizer 100 is used to load an aerosol-generating substrate and, when powered, heat the aerosol-generating substrate. When powered by the battery assembly 300, the atomizer 100 can heat the aerosol-generating substrate to generate an aerosol for inhalation by the user. The atomizer 100 can heat the aerosol-generating substrate using, but is not limited to, resistive heating, microwave heating, or laser irradiation.

[0039] See also Figures 2 to 4 The atomizer 100 of the embodiment of the present application includes a storage unit 10, a cartridge tube 20, a heating element 30 and a sealing member 40. The storage unit 10 is provided with a loading chamber 11, and the loading chamber 11 is used to load an aerosol generating matrix. The cartridge tube 20 is installed in the loading chamber 11, and the cartridge tube 20 is provided with a mounting chamber 231 and a first air channel 211, and the mounting chamber 231 is connected to the first air channel 211 and the loading chamber 11. The heating element 30 is installed in the mounting chamber 231, and the heating element 30 is provided with an atomization chamber 31 running through the opposite ends, and the atomization chamber 31 is connected to the first air channel 211. The sealing member 40 is installed in the mounting chamber 231 and is located between the cartridge tube 20 and the heating element 30. The sealing member 40 is provided with an oil storage groove 41 on the side facing the atomization chamber 31, and the oil storage groove 41 is connected to the atomization chamber 31.

[0040] Specifically, the storage element 10 is a structure for storing an aerosol-generating substrate. The cross-sectional shape of the storage element 10 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal. The loading chamber 11 is used to load the aerosol-generating substrate therein and also to accommodate the cigarette cartridge tube 20 therein.

[0041] See also Figure 3 and Figure 4, the cigarette cartridge tube 20 is used to install the heating element 30 and to guide the aerosol to the outside of the atomizer 100 for the user to inhale. Preferably, the cigarette cartridge tube 20 can be made of a high-temperature resistant material. For example, the cigarette cartridge tube 20 can be made of materials such as metal or ceramic, so that the cigarette cartridge tube 20 is not easily damaged when the heating element 30 generates heat, and the cigarette cartridge tube 20 can also guide the high-temperature aerosol, and the service life of the cigarette cartridge tube 20 is longer. Since the aerosol generated by the aerosol generating matrix will contact the inner wall of the cigarette cartridge tube 20, preferably, the cigarette cartridge tube 20 can be made of food-grade stainless steel. The mounting cavity 231 is used for the heating element 30 and the seal 40 to be installed therein. When the mounting cavity 231 is connected to the loading cavity 11, the aerosol generating matrix in the loading cavity 11 can enter the mounting cavity 231 to be heated by the heating element 30 to generate an aerosol. The first air channel 211 is used to allow the aerosol generated in the mounting cavity 231 to flow out of the atomizer 100 for inhalation by the user.

[0042] See also Figure 3 and Figure 4 The heating element 30 is a structure that can generate heat when energized. The heating element 30 generates heat to heat the aerosol generating matrix located near the heating element 30, and the heated aerosol generating matrix can generate aerosol. In some embodiments, the heating element 30 may include a heating body 33, a heating wire 35, a first lead 37 and a second lead 39. The heating wire 35 is embedded in the heating body 33, and the heating wire 35 can generate heat when energized. One end of the first lead 37 is electrically connected to one electrode (positive or negative) of the heating wire 35, and the other end of the second lead 39 is electrically connected to the other electrode (negative or positive) of the heating wire 35. Both the first lead 37 and the second lead 39 are electrically connected to the battery assembly 300.

[0043] The heating body 33 can be a porous ceramic material. Porous ceramics are usually prepared by mixing ceramic slurry with a pore-forming agent and then injection molding and sintering. The sintered ceramic body has a large number of micropores. The aerosol-generating matrix entering the installation cavity 231 can enter the interior of the porous ceramic through multiple micropores. When the user inhales the aerosol generating device 1000, the battery assembly 300 supplies power to the heating wire 35 through the first lead 37 and the second lead 39. When the heating wire 35 is energized, it generates heat, thereby heating the surface of the heating body 33 and the aerosol-generating matrix entering the micropores, so that the aerosol-generating matrix can generate aerosol.

[0044] The heating element 30 of the present application is generally cylindrical in structure, with an atomizing chamber 31 disposed in the center of the heating body 33. When the heating wire 35 heats the surface of the heating body 33 and the aerosol-generating substrate within the heating body 33, the aerosol generated by the aerosol-generating substrate enters the atomizing chamber 31. When the user draws in, the aerosol in the atomizing chamber 31 can flow out of the atomizer 100 through the first airway 211.

[0045] See also Figure 3 and Figure 4 In some embodiments, the atomizer 100 further includes a mounting base 50 and an electrical connector 70. The mounting base 50 is connected to both the storage unit 10 and the cartridge tube 20, and the electrical connector 70 is mounted on the mounting base 50. The electrical connector 70 is provided with a second air channel 73, which is in communication with the atomizing chamber 31. The second air channel 73 is used to allow external air to enter. When a user inhales, the external air passes through the battery assembly 300 into the second air channel 73, and then enters the atomizing chamber 31 from the second air channel 73. The air carries the aerosol in the atomizing chamber 31 and flows out of the atomizer 100 through the first air channel 211 for the user to inhale. The first air channel 211, the atomizing chamber 31 and the second air channel 73 of the present application correspond to and are connected. When the user inhales, the external gas can quickly enter the atomizing chamber 31 through the second air channel 73, and carry the aerosol through the first air channel 211 to flow out of the atomizer 100. The flow path of the airflow is short, and the aerosol can quickly flow out of the atomizer 100, so the user has a better inhalation experience.

[0046] See also Figure 3 and Figure 4 The seal 40 is used to seal the gap between the heating element 30 and the cartridge tube 20, thereby preventing the aerosol-generating matrix that enters the mounting cavity 231 from flowing out through the gap between the heating element 30 and the cartridge tube 20 into the first airway 211 and / or the second airway 73, thereby blocking the first airway 211 and / or the second airway 73. The seal 40 can be made of materials such as rubber, silicone, plastic, or synthetic fiber. Examples of rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.

[0047] Because the heating element 30 is made of a porous ceramic material, when a user inhales, the aerosol-generating matrix within the micropores of the heating element 30 may leak out and block the first airway 211 and / or the second airway 73, preventing the user from continuing to inhale. The oil reservoir 41 of the present application is used to store the aerosol-generating matrix leaking from the heating element 30, thereby preventing the aerosol-generating matrix from entering the first airway 211 and / or the second airway 73 and blocking them.

[0048] When the seal 40 is connected to the upper end of the heating element 30 and the oil storage tank 41 is located at the upper end of the heating element 30, the oil storage tank 41 is used to store the aerosol-generating substrate leaking from the upper end of the heating element 30, thereby preventing the aerosol-generating substrate from clogging the first air passage 211. When the seal 40 is connected to the lower end of the heating element 30 and the oil storage tank 41 is located at the lower end of the heating element 30, the oil storage tank 41 is used to store the aerosol-generating substrate leaking from the lower end of the heating element 30, thereby preventing the aerosol-generating substrate from clogging the second air passage 73.

[0049] Since the oil storage tank 41 is adjacent to the heating element 30, the temperature inside the oil storage tank 41 is relatively high, and the viscosity of the aerosol generating matrix (high-viscosity sesame oil) will not decrease (fluidity deteriorates) due to the low temperature after entering the oil storage tank 41, and the aerosol generating matrix in the oil storage tank 41 can maintain good fluidity. After the user finishes inhaling, the aerosol generating matrix in the oil storage tank 41 can be sucked back into the heating element 30 again due to the negative pressure in the installation cavity 231. The aerosol generating matrix that enters the heating element 30 again can be heated by the heating wire 35. The present application can effectively prevent the aerosol generating matrix from entering the first airway 211 and / or the second airway 73 by arranging the oil storage tank 41 on the sealing member 40, so as to avoid the problem that the temperature of the aerosol generating matrix in the first airway 211 and / or the second airway 73 is relatively low, resulting in an increase in the viscosity of the aerosol generating matrix (high-viscosity sesame oil) and blocking the first airway 211 and / or the second airway 73.

[0050] In the atomizer 100 of the embodiment of the present application, when the user draws inhalation, a small amount of the aerosol-generating matrix inside the heating element 30 may leak out. The aerosol-generating matrix leaked from the heating element 30 can be stored in the oil reservoir 41. After the user finishes drawing inhalation, the aerosol-generating matrix in the oil reservoir 41 can be sucked back into the heating element 30 again, thereby preventing the aerosol-generating matrix leaked from the heating element 30 from entering the airway and clogging the airway. The aerosol can flow smoothly through the airway to the outside of the atomizer 100, and the user's drawing inhalation is smoother, and the user's drawing experience is better.

[0051] The atomizer 100 will be further described below with reference to the accompanying drawings.

[0052] See also Figure 3 and Figure 4 In some embodiments, the cartridge tube 20 includes a first sub-section 21 and a second sub-section 23 connected to each other. The first sub-section 21 is provided with a first airway 211, and the second sub-section 23 is provided with an installation cavity 231. The peripheral wall 42 of the second sub-section 23 is provided with a through hole 233, and the through hole 233 connects the loading cavity 11 and the installation cavity 231.

[0053] Among them, the through hole 233 is used to allow the aerosol generating matrix in the loading chamber 11 to enter the installation chamber 231, so that the aerosol generating matrix can enter the micropores of the heating body 33 to be heated by the heating wire 35. Preferably, the through hole 233 can correspond to the peripheral wall 42 of the heating body 30, so that the aerosol generating matrix in the loading chamber 11 can quickly enter the heating body 33 after passing through the through hole 233, and the interior of the heating body 33 can always maintain a state of aerosol generating matrix, which can avoid the problem of burning due to lack of aerosol generating matrix in the heating body 33. The number of through holes 233 can be one, two, three, four or more. In the case of a plurality of through holes 233, more aerosol generating matrix enters the interior of the heating body 33 through the through holes 233 per unit time, which can further avoid the problem of burning due to lack of aerosol generating matrix in the heating body 33.

[0054] The first sub-section 21 is used to guide the aerosol in the installation cavity 231 to flow out of the atomizer 100, and the second sub-section 23 is used to install the heating element 30 and the seal 40. The first sub-section 21 and the second sub-section 23 can be an integral structure or a split structure. In the case where the first sub-section 21 and the second sub-section 23 are an integral structure, the first sub-section 21 and the second sub-section 23 can be integrally formed, and the processing steps of the cigarette cartridge tube 20 are relatively simple. In the case where the first sub-section 21 and the second sub-section 23 are split structures, the first sub-section 21 and the second sub-section 23 can be detachably or non-detachably connected. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0055] See also Figure 4 and Figure 6 In some embodiments, the seal 40 includes a peripheral wall 42 and a top wall 43 connected to the peripheral wall 42. At least a portion of the peripheral wall 42 of the seal 40 is sleeved onto the heating element 30. The top wall 43 of the seal 40 is spaced from the end of the heating element 30. The top wall 43 and the peripheral wall 42 of the seal 40 together form an oil reservoir 41. In this case, the seal 40 has a relatively simple structure and is relatively easy to manufacture.

[0056] See also Figures 4 to 6 In some embodiments, the seal 40 further includes at least two protrusions 45 spaced apart from each other. The protrusions 45 extend from the inner side of the peripheral wall 42 toward the center of the atomization chamber 31. The protrusions 45 are connected to the top wall 43 and abut against the end of the heating element 30. The at least two protrusions 45, the top wall 43, and the peripheral wall 42 together form at least two oil storage grooves 41.

[0057] The number of protrusions 45 may be, but is not limited to, two, three, four or more, and a plurality of protrusions 45 may be distributed in an array on the inner side of the peripheral wall 42 of the seal 40. The number of oil reservoirs 41 may be, but is not limited to, two, three, four or more. In the case where the seal 40 includes a protrusion 45, during the process of connecting the seal 40 to the heating element 30, when the protrusion 45 abuts against the end of the heating element 30, it may indicate that the seal 40 is installed in place. The protrusion 45 can play a better positioning role in the installation of the seal 40, and the installation between the seal 40 and the heating element 30 is relatively simple and quick.

[0058] See also Figures 7 to 9 Furthermore, in some embodiments, the sealing member 40 is further provided with a liquid conducting groove 47 , which is communicated with the oil storage groove 41 , and the liquid conducting groove 47 corresponds to the peripheral wall 42 of the heating element 30 .

[0059] Specifically, in some embodiments, the inner side surface of the peripheral wall 42 of the seal 40 is recessed in a direction away from the center of the atomization chamber 31 to form a liquid guide groove 47. In the length direction of the atomizer 100, one end of the liquid guide groove 47 is connected to the oil storage groove 41, and the side wall of the liquid guide groove 47 is spaced from the heating element 30. The peripheral wall 42 of the seal 40 located on the opposite side of the liquid guide groove 47 and the oil storage groove 41 abuts against the heating element 30.

[0060] The number of liquid-conducting grooves 47 is the same as the number of oil-reservoir grooves 41. The oil-reservoir grooves 41 are located at the ends of the heating element 30. When the user inhales, the aerosol-generating matrix in the heating element 30 enters the oil-reservoir grooves 41, and the aerosol-generating matrix in the oil-reservoir grooves 41 flows toward the liquid-conducting grooves 47. After the user finishes inhaling, the aerosol-generating matrix in the oil-reservoir grooves 41 is sucked back from the ends of the heating element 30 by the heating element 30, and the aerosol-generating matrix in the liquid-conducting grooves 47 is sucked back from the peripheral wall 42 of the heating element 30 by the heating element 30. That is, the contact area between the aerosol-generating matrix and the surface of the heating element 30 is larger, thereby accelerating the efficiency of the aerosol-generating matrix's reabsorption, and further reducing the risk of the aerosol-generating matrix clogging the first air passage 211 and / or the second air passage 73.

[0061] The peripheral wall 42 of the sealing member 40 at one end away from the heating element 30 abuts against the heating element 30. At this time, the liquid guide groove 47 is not connected to the mounting cavity 231. The aerosol generating matrix in the liquid guide groove 47 can be quickly sucked back by the heating element 30, so that the heating element 30 can always maintain a state of having an aerosol generating matrix, thereby avoiding the problem of burning due to lack of aerosol generating matrix inside the heating body 33.

[0062] See also Figure 4 and Figure 7In some embodiments, the sealing member 40 includes a first sealing member 48, which is located between the end of the second sub-section 23 near the first sub-section 21 and the heating element 30. The first sealing member 48 is used to prevent the aerosol-generating substrate from entering the mounting cavity 231 through the through hole 233 and flowing into the first airway 211 through the gap between the end of the second sub-section 23 near the first sub-section 21 and the heating element 30. This prevents the aerosol-generating substrate from flowing out of the first airway 211 and out of the atomizer 100, and also prevents the aerosol-generating substrate from accumulating in the first airway 211 and clogging the first airway 211.

[0063] See also Figures 4 to 6 In one embodiment, the first sealing member 48 is provided with only the oil reservoir 41. In this case, the first sealing member 48 has a relatively simple structure and is relatively easy to manufacture. During inhalation, a portion of the aerosol-generating substrate within the heating element 30 may flow out of the heating element 30 (toward the upper end of the heating element 30) toward the first airway 211 due to the negative pressure of inhalation. The aerosol-generating substrate that flows to the upper end of the heating element 30 can be stored in the oil reservoir 41. The top wall 43 of the heating element 30 then acts as a barrier to the aerosol-generating substrate within the oil reservoir 41. This effectively prevents the aerosol-generating substrate within the oil reservoir 41 from flowing toward the first airway 211 during inhalation, further preventing the aerosol-generating substrate from entering the first airway 211. After the user finishes inhaling, the aerosol-generating substrate within the oil reservoir 41 is drawn back into the heating element 30, where it can be heated by the heating element 30 to generate an aerosol.

[0064] See also Figures 7 to 9 In another embodiment, the first sealing member 48 is provided with an oil storage groove 41 and a liquid guide groove 47. At this time, the aerosol generating matrix located in the oil storage groove 41 and the liquid guide groove can be quickly sucked back by the heating element 30, and the aerosol generating matrix has a high re-absorption efficiency. When the user inhales, a portion of the aerosol generating matrix in the heating element 30 may flow out to the outside of the heating element 30 (the upper end of the heating element 30) in the direction of the first airway 211 due to the suction negative pressure, and the aerosol generating matrix flowing to the upper end of the heating element 30 will be stored in the oil storage groove 41 and the liquid guide groove 47. At this time, the top wall 43 of the heating element 30 will have a certain blocking effect on the aerosol generating matrix airway in the oil storage groove 41 and the liquid guide groove 47, so that when the user inhales, the aerosol generating matrix in the oil storage groove 41 and the liquid guide groove 47 can be effectively prevented from flowing toward the first airway 211, thereby further avoiding the problem of the aerosol generating matrix blocking the first airway 211. After the user finishes inhaling, the aerosol generating matrix in the oil storage tank 41 and the liquid guiding tank 47 will be sucked back into the heating element 30 , and this part of the aerosol generating matrix can be heated by the heating element 30 to generate aerosol.

[0065] See also Figure 3 、 Figure 4 and Figure 7 In some embodiments, the atomizer 100 further includes a bracket 60 , which is installed in the mounting seat 50 , and the storage element 10 and the second sub-section 23 are both connected to the mounting seat 50 .

[0066] The mounting base 50 is used to support the structure of the cartridge tube 20, the heating element 30, and the sealing member 40. The inner side surface of the upper end of the mounting base 50 is connected to the inner side wall of the storage element 10, and the outer side surface of the lower end of the mounting base 50 is provided with threads. The mounting base 50 is connected to the battery assembly 300 through the threads, thereby firmly connecting the atomizer 100 and the battery assembly 300.

[0067] The atomizer 100 also includes a first decorative member 90, which is sleeved onto the outer walls of the storage element 10 and the mounting base 50. The first decorative member 90 serves to conceal the connection between the storage element 10 and the mounting base 50, thereby enhancing the aesthetics of the atomizer 100. The first decorative member 90 of the present application is made of metal to further enhance the aesthetics of the atomizer 100. Preferably, the first decorative member 90, the storage element 10, and the mounting base 50 each have an interference fit, ensuring a secure connection between the storage element 10 and the mounting base 50 and preventing loosening.

[0068] See also Figure 3 、 Figure 4 and Figure 7 At least a portion of the second sub-portion 23 of the cartridge tube 20 extends into the mounting seat 50. The second sub-portion 23 and the inner side surface of the mounting seat 50 may form an interference fit, in which case the connection between the second sub-portion 23 and the mounting seat 50 is relatively stable. A groove 51 is provided on the inner side surface of the mounting seat 50. The inner side surface of the mounting seat 50 and the second sub-portion 23 together form a ventilation channel 53, which is connected to the loading chamber 11. The bracket 60 is used to support the second sealing member 49 of the atomizer 100. The bracket 60 may be provided with a perforation and an air guide groove. The through hole 233 is connected to the second air channel 73, and the air guide groove connects the perforation and the ventilation channel 53. When the user inhales, the external gas enters the second air channel 73 through the battery assembly 300, and part of the gas enters the ventilation channel 53 through the perforation and the air guide groove. The gas in the ventilation channel 53 enters the loading chamber 11 to balance the air pressure in the loading chamber 11, thereby ensuring that the aerosol generating matrix in the loading chamber 11 can smoothly flow into the installation chamber 231 through the through hole 233.

[0069] See also Figure 3 、 Figure 4 and Figure 7 Furthermore, in some embodiments, the sealing member 40 further includes a second sealing member 49 , which is located between the heating element 30 and the bracket 60 .

[0070] The second seal 49 is used to prevent the aerosol-generating substrate from entering the mounting cavity 231 through the through hole 233 and flowing into the second air passage 73 through the gap between the heating element 30 and the bracket 60. This prevents the aerosol-generating substrate from flowing into the battery assembly 300 through the second air passage 73, and also prevents the aerosol-generating substrate from accumulating in the second air passage 73 and clogging the second air passage 73. The second seal 49 can be mounted on the lower end of the heating element 30, that is, part of the second seal 49 can be located between the heating element 30 and the second sub-section 23, and another part of the second seal 49 can be located between the heating element 30 and the bracket 60. Thus, the second seal 49 can further prevent the aerosol-generating substrate in the mounting cavity 231 from flowing into the second air passage 73.

[0071] See also Figures 4 to 6 In one embodiment, the second sealing member 49 is provided with only an oil reservoir 41. In this case, the structure of the second sealing member 49 is relatively simple and the processing is relatively simple. Due to gravity, a portion of the aerosol-generating matrix within the heating element 30 may flow out of the heating element 30 (the lower end of the heating element 30) toward the second air passage 73. The aerosol-generating matrix that flows to the lower end of the heating element 30 will be stored in the oil reservoir 41. At this time, the top wall 43 of the heating element 30 will have a certain blocking effect on the aerosol-generating matrix within the oil reservoir 41. Therefore, when the user inhales, the aerosol-generating matrix within the oil reservoir 41 can be effectively prevented from flowing toward the second air passage 73, thereby further preventing the problem of the aerosol-generating matrix clogging the second air passage 73. After the user finishes inhaling, the aerosol-generating matrix within the oil reservoir 41 will be sucked back into the heating element 30, and this portion of the aerosol-generating matrix can be heated by the heating element 30 to generate an aerosol.

[0072] See also Figures 7 to 9In another embodiment, the second sealing member 49 is provided with an oil storage groove 41 and a liquid guide groove 47. At this time, the aerosol generating matrix located in the oil storage groove 41 and the liquid guide groove 47 can be quickly sucked back by the heating element 30, and the re-absorption efficiency of the aerosol generating matrix is ​​relatively high. When the user inhales, a portion of the aerosol generating matrix in the heating element 30 may flow out to the outside of the heating element 30 (the lower end of the heating element 30) in the direction of the second air channel 73 due to gravity. The aerosol generating matrix flowing to the lower end of the heating element 30 will be stored in the oil storage groove 41 and the liquid guide groove 47. At this time, the top wall 43 of the heating element 30 will play a certain blocking role on the aerosol generating matrix in the oil storage groove 41 and the liquid guide groove 47, so that when the user inhales, the aerosol generating matrix in the oil storage groove 41 and the liquid guide groove 47 can be effectively prevented from flowing toward the second air channel 73, thereby further avoiding the problem of the aerosol generating matrix blocking the second air channel 73. After the user finishes inhaling, the aerosol generating matrix in the oil storage tank 41 and the liquid guiding tank 47 will be sucked back into the heating element 30 , and this part of the aerosol generating matrix can be heated by the heating element 30 to generate aerosol.

[0073] In other embodiments, the second sealing member 49 may not be provided with the oil reservoir 41 and the liquid guide groove 47. The second sealing member 49 may simply be mounted on the lower end of the heating element 30 to prevent the aerosol-generating substrate in the mounting cavity 231 from flowing into the second air passage 73. In this case, the structure of the second sealing member 49 is simpler and easier to manufacture.

[0074] See also Figure 3 、 Figure 4 and Figure 7 In some embodiments, the mounting base 50 is conductive, and the electrical connector 70 is installed in the mounting base 50 through an insulating fixing member 71. The mounting base 50 is connected to one electrode of the heating element 30, and the electrical connector 70 is connected to another electrode of the heating element 30.

[0075] The mounting base 50 may be made of a conductive material. Among them, the conductive material includes but is not limited to a conductive metal material and a conductive carbon material. Conductive metal materials may include copper, aluminum, iron and silver, etc., and conductive carbon materials may include graphite, carbon black and carbon fiber, etc. The mounting base 50 and the electrical connector 70 are electrically connected to the positive and negative electrodes of the battery assembly 300 respectively. The mounting base 50 is electrically connected to one electrode (positive or negative) of the heating wire 35 through the first lead 37, and the electrical connector 70 is electrically connected to the other electrode (negative or positive) of the heating wire 35 through the second lead 39 to form a current loop. When the user draws air, the electrical energy of the battery assembly 300 enters the heating wire 35 through the current loop, so that the heating wire 35 can generate heat to heat the aerosol generating matrix.

[0076] The fixing member 71 is used to fix the electrical connector 70 in the mounting base 50. Since both the electrical connector 70 and the mounting base 50 are made of conductive materials, the fixing member 71 is also used to separate the electrical connector 70 and the mounting base 50. The fixing member 71 can be made of non-conductive material to avoid the problem of short circuit between the electrical connector 70 and the mounting base 50.

[0077] See also Figure 3 、 Figure 4 and Figure 7 Furthermore, in some embodiments, the atomizer 100 further includes a mouthpiece 80 and a third sealing member 81. The mouthpiece 80 is connected to the end of the storage element 10 away from the mounting base 50. The mouthpiece 80 is provided with a third air passage 83, which is in communication with the first air passage 211. The third sealing member 81 is provided between the storage element 10 and the mouthpiece 80 and is used to seal the gap between the storage element 10 and the mouthpiece 80.

[0078] Specifically, when a user draws on the aerosol generating device 1000, the battery assembly 300 supplies power to the atomizer 100, and the user draws in the aerosol generated in the atomizer 100 through the mouthpiece 80. When the user draws in, external air enters the aerosol generating device 1000 from the battery assembly 300, then enters the second air passage 73 from the battery assembly 300. The air in the second air passage 73 enters the atomization chamber 31, and the air carries the aerosol in the atomization chamber 31 through the first air passage 211 into the third air passage 83. The air then flows out of the aerosol generating device 1000 from the third air passage 83 to be drawn by the user.

[0079] The first sub-section 21 of the present application extends into the third airway 83. The first sub-section 21 cooperates with the inner wall of the third airway 83 to connect the first airway 211 with the third airway 83. The first sub-section 21 is securely mounted, preventing it from wobbling within the loading chamber 11. Preferably, the peripheral wall 42 of the first sub-section 21 is provided with a protrusion 213, which creates an interference fit with the inner wall of the third airway 83. This effectively prevents aerosol from escaping from the gap between the first and third airways 211 and 83, thus avoiding aerosol waste and providing a better user experience. Furthermore, the interference fit between the first sub-section 21 and the inner wall of the third airway 83 reduces the inhalation resistance between the first and third airways 211 and 83 when the user inhales, resulting in a smoother inhalation experience.

[0080] The third seal 81 is used to prevent the aerosol-generating substrate in the loading chamber 11 from entering the third airway 83 through the gap between the storage element 10 and the mouthpiece 80, or even from flowing out of the atomizer 100. This effectively prevents waste of the aerosol-generating substrate and improves the user experience. The third seal 81 can be made of, but is not limited to, rubber, silicone, plastic, or synthetic fiber.

[0081] See also Figure 3 、 Figure 4 and Figure 7 In some embodiments, the atomizer 100 may further include a second decorative member 91, which is sleeved onto the outer wall of the nozzle 80 and the outer wall of the storage member 10. The second decorative member 91 is used to cover the connection between the storage member 10 and the nozzle 80 to enhance the aesthetics of the atomizer 100. The second decorative member 91 of the present application is made of a metal material, which can further enhance the aesthetics of the atomizer 100. The second decorative member 91 can have an interference fit with both the nozzle 80 and the storage member 10, thereby ensuring a more stable connection between the storage member 10 and the nozzle 80 and preventing loosening between the storage member 10 and the nozzle 80.
