[0034] At present, most aerosol generating devices adopt a side atomization method, that is, the heating element is placed sideways in the storage chamber, and the aerosol generating matrix in the storage chamber contacts one side of the heating element and enters the other side of the heating element to be heated by the heating element to generate an aerosol. However, during the user's inhalation, the aerosol in contact with the side wall of the bracket will condense, and the condensed aerosol will easily fall into the air guide port, blocking the air guide port, resulting in external gas being unable to enter the atomization chamber. In order to solve this problem, the embodiment of the present application provides a nebulizer 100 ( Figure 1 ) and aerosol generating device 1000 ( Figure 7 shown).

[0035] See also Figures 1 to 3The atomizer 100 of the embodiment of the present application includes a storage element 10, a bracket 30 and a heating element 50. The storage element 10 includes a first end 11 and a second end 13 opposite to each other, and is provided with a storage cavity 15 and an air guide cavity 17 spaced apart from each other, and the storage cavity 15 is used to store the aerosol generating matrix. The bracket 30 is connected to the first end 11 of the storage element 10, and the bracket 30 and the storage element 10 jointly form an atomization cavity 31, and the atomization cavity 31 is connected to the air guide cavity 17. The bottom wall of the atomization cavity 31 is provided with a first air guide port 331 and a second air guide port 351, and the first air guide port 331 and the second air guide port 351 are both connected to the atomization cavity 31 and are used to introduce external gas. In a plane perpendicular to the length direction H of the atomizer 100, the projection of the first air guide port 331 at least partially overlaps with the projection of the air guide cavity 17, and the projection of the second air guide port 351 is spaced apart from the projection of the air guide cavity 17. The heating element 50 is installed on the storage element 10 and is located in the atomization chamber 31. The heating element 50 is used to heat the aerosol generating matrix in the storage chamber 15 to generate aerosol. The air guide chamber 17 is used to allow the aerosol to flow out.

[0036] See also Figure 1 Specifically, the atomizer 100 of the present application is a structure disposed in the aerosol generating device 1000, and is used to energize to heat the aerosol generating substrate to generate an aerosol for the user to inhale. The heating method of the atomizer 100 to heat the aerosol generating substrate may be, but is not limited to, resistive heating, microwave heating, or laser irradiation heating.

[0037] The aerosol generating device 1000 is a structure capable of generating an aerosol by heating an aerosol generating substrate. The aerosol 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 generating substrate is a product that has been processed and heated to generate an aerosol. The form of the aerosol generating substrate may be liquid, or may be fully solid or semi-solid. In the case where the aerosol generating substrate is liquid, the liquid aerosol generating substrate is a mixed liquid in which substances such as nicotine and nicotine are dissolved, and its solute is a common organic solute and / or inorganic solute such as propylene glycol, vegetable glycerin and pure water. In the present application, the aerosol generating substrate may be a high-viscosity tobacco oil (e.g., sesame oil, etc.), which can generate an aerosol when heated.

[0038] Please combine Figure 7 The aerosol generating device 1000 of the embodiment of the present application further includes a battery assembly 300, and the atomizer 100 is electrically connected to the battery assembly 300. The battery assembly 300 can be used to supply power to the heating element 50, so that the heating element 50 can generate heat to heat the aerosol generating substrate.

[0039] See also Figure 2 and Figure 3The storage element 10 is a structure for storing an aerosol-generating matrix, and the storage element 10 is also used to allow aerosols and gases to flow therethrough. When the atomizer 100 is in a vertical state, the first end 11 of the storage element 10 is the lower end, and the second end 13 of the storage element 10 is the upper end. The storage element 10 includes a body 12 and a partition 14. The body 12 may be a columnar structure. The partition 14 is installed in the body 12 and divides the cavity of the body 12 into a storage cavity 15 and an air guide cavity 17 that are not connected to each other. The body 12 and the partition 14 may be an integral structure or a split structure. When the body 12 and the partition 14 are an integral structure, the body 12 and the partition 14 may be integrally formed, and the assembly steps of the storage element 10 are relatively simple. When the body 12 and the partition 14 are split structures, the replacement and maintenance of the partition 14 can be facilitated. At this time, the partition 14 can be detachably or non-detachably installed on the body 12. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection. Non-detachable installation methods include but are not limited to welding, gluing or interference fit.

[0040] The storage chamber 15 is used to store the aerosol generating substrate therein, and the air guiding chamber 17 is used to allow the aerosol and gas to flow therethrough. Preferably, the volume of the storage chamber 15 is larger than the volume of the air guiding chamber 17, so that more aerosol generating substrate can be stored in the storage element 10. The user does not need to frequently add the aerosol generating substrate to the storage element 10, and the user's use experience is better.

[0041] A ventilation channel 18 is provided in the storage chamber 15, one end of the ventilation channel 18 is connected to the atomizing chamber 31, and the other end of the ventilation channel 18 is connected to the storage chamber 15. During the user's inhalation, external gas enters the atomizing chamber 31, and the gas entering the atomizing chamber 31 can enter the storage chamber 15 through the ventilation channel 18. During the consumption of the aerosol generating device 1000 in the storage chamber 15, the gas can enter the storage chamber 15 from the ventilation channel 18 to balance the air pressure in the storage chamber 15, and ensure that the aerosol generating matrix in the storage chamber 15 can flow smoothly to the heating element 50, avoiding the problem of burning due to the absence of aerosol generating matrix around the heating element 50. Since the aerosol generating matrix of the embodiment of the present application is high-viscosity sesame oil, the viscosity of the aerosol generating matrix is ​​relatively high, and only a small part of the aerosol generating matrix in the storage chamber 15 or even almost no aerosol generating matrix will flow into the atomizing chamber 31 from the ventilation channel 18, which can avoid the problem of a large amount of leakage of the aerosol generating matrix in the storage chamber 15.

[0042] See also Figures 2 to 4, the bracket 30 is detachably connected to the first end 11 of the storage element 10. Specifically, the bracket 30 of the present application is snap-connected to the first end 11 of the storage element 10. In one embodiment, the first end 11 of the storage element 10 is provided with a protrusion, and the bracket 30 is provided with a groove 36. The protrusion cooperates with the groove 36, so that the storage element 10 and the bracket 30 can be firmly connected. In another embodiment, the first end 11 of the storage element 10 is provided with a groove 36, and the bracket 30 is provided with a protrusion. The groove 36 cooperates with the protrusion, so that the storage element 10 and the bracket 30 can be firmly connected. The first end 11 of the storage element 10 of the embodiment of the present application is provided with a protrusion, and the bracket 30 is provided with a groove 36. The number of protrusions can be one, two, three or more, and the number of grooves 36 is the same as the number of protrusions. The number of grooves 36 of the present application is two, and the two grooves 36 are evenly distributed on the bracket 30. The number of protrusions is two, and the positions of the two protrusions on the first end 11 of the storage element 10 correspond to the positions of the two grooves 36 respectively.

[0043] The bracket 30 and the first end 11 of the storage element 10 together form an atomization chamber 31. The atomization chamber 31 is used for the heating element 50 to heat the aerosol generating substrate therein, and the heated aerosol generating substrate generates aerosol. The aerosol in the atomization chamber 31 can flow out of the atomizer 100 from the air guide chamber 17 and be inhaled by the user.

[0044] See also Figures 2 to 4 , the first air guide port 331 is used to allow external gas to enter the atomizing chamber 31, and the second air guide port 351 is used to allow external gas to enter the atomizing chamber 31. The cross-sectional shape of the first air guide port 331 may be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes. The cross-sectional shape of the second air guide port 351 may be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes. During the user's inhalation process, external gas enters the atomizing chamber 31 from the first air guide port 331 and the second air guide port 351, and the gas entering the atomizing chamber 31 carries the aerosol in the atomizing chamber 31 and flows out of the atomizer 100 from the air guide chamber 17 and is inhaled by the user.

[0045] In a plane perpendicular to the length direction H of the atomizer 100, at least part of the projection of the first air guide port 331 overlaps with the projection of the air guide cavity 17, that is, in the length direction H of the atomizer 100, at least part of the first air guide port 331 corresponds to the air guide cavity 17. In a plane perpendicular to the length direction H of the atomizer 100, the projection of the first air guide port 331 may partially overlap with the projection of the air guide cavity 17, and the projection of the first air guide port 331 may also completely overlap with the projection of the air guide cavity 17. In a plane perpendicular to the length direction H of the atomizer 100, when at least part of the projection of the first air guide port 331 overlaps with the projection of the air guide cavity 17, the external gas entering from the first air guide port 331 can directly and quickly carry the aerosol in the atomization cavity 31 out of the air guide cavity 17, which can minimize the problem of the aerosol contacting the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 to condense and form condensate, and can reduce the deposition rate of the aerosol in the atomization cavity 31. The amount of aerosol inhaled by the user per unit time is large, and the user's inhalation experience is good.

[0046] However, in the case of only the first air guide port 331, the condensate formed by the contact between the aerosol and the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 is easy to fall into the first air guide port 331, and there will be a problem of blocking the first air guide port 331. The present application is also provided with a second air guide port 351 spaced apart from the first air guide port 331. In a plane perpendicular to the length direction H of the atomizer 100, the projection of the second air guide port 351 is spaced apart from the projection of the air guide cavity 17, that is, in the length direction H of the atomizer 100, the second air guide port 351 does not correspond to the air guide cavity 17. At this time, in the case of the condensate formed by the contact between the aerosol and the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 falling, this part of the condensate is not easy to fall into the second air guide port 351, thereby avoiding the problem of clogging of the second air guide port 351. During the inhalation process of the user, external gas enters the atomizing chamber 31 from the first air guide port 331 and the second air guide port 351, and the gas entering the atomizing chamber 31 carries the aerosol in the atomizing chamber 31 and flows out of the atomizer 100 from the air guide chamber 17 and is inhaled by the user. At this time, even if the first air guide port 331 is blocked by the condensate formed after the aerosol is condensed, the second air guide port 351 can allow external gas to enter the atomizing chamber 31 and carry the aerosol in the atomizing chamber 31 to flow out of the atomizing chamber 31, thereby avoiding the problem that the external gas cannot enter the atomizing chamber 31.

[0047] See also Figures 2 to 4The heating element 50 is a structure that can generate heat when powered. When the battery assembly 300 supplies power to the heating element 50, the heating element 50 can generate heat to heat the aerosol generating matrix located near the heating element 50, and the heated aerosol generating matrix can generate aerosol. The heating element 50 can be a porous ceramic material. The porous ceramic is usually prepared by mixing a ceramic slurry with a pore-forming agent and then sintering. The sintered ceramic body has a large number of micropores. The heating element 50 is installed at the first end 11 of the storage element 10. The heating element 50 is located in the atomization chamber 31 and is at least partially connected to the storage chamber 15, so that the aerosol generating matrix in the storage chamber 15 can contact the heating element 50 and enter the porous ceramic through the micropores. When the heating element 50 generates heat, the aerosol generating matrix that contacts the heating element 50 and enters the micropores will be heated to generate aerosol. The generated aerosol enters the atomizing chamber 31 and enters the air guiding chamber 17 from the atomizing chamber 31 along with the gas in the atomizing chamber 31 . The aerosol flows out of the air guiding chamber 17 to the outside of the atomizer 100 for inhalation by the user.

[0048] The atomizer 100 also includes a first seal 51, which is arranged around the heating element 50 and is used to seal the gap between the heating element 50 and the first end 11 of the storage element 10. The first seal 51 can be made of materials such as rubber, silicone, plastic or synthetic fiber. Preferably, the number of the first seals 51 can be two. When the number of the first seals 51 is two, the sealing effect of the first seal 51 is better. The first seal 51 can prevent the aerosol generating matrix in the storage chamber 15 from entering the atomization chamber 31 from the gap between the heating element 50 and the first end 11 of the storage element 10, which can avoid the waste of the aerosol generating matrix, and also avoid the problem that the aerosol generating matrix flows into the first air guide port 331 and / or the second air guide port 351 to block the first air guide port 331 and / or the second air guide port 351.

[0049] In the atomizer 100 of the embodiment of the present application, in a plane perpendicular to the length direction H of the atomizer 100, the projection of the first air guide port 331 at least partially overlaps with the projection of the air guide cavity 17, and the projection of the second air guide port 351 is spaced from the projection of the air guide cavity 17. During the user's inhalation process, the first air guide port 331 can allow external gas to enter the atomization cavity 31, and this part of the gas carries the aerosol in the atomization cavity 31 and flows out of the air guide cavity 17 and is inhaled by the user. The first air guide port 331 can minimize the problem of aerosol contacting the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 and condensing. The second air guide port 351 can allow external gas to enter the atomization cavity 31. In the case where the condensate formed by the aerosol falls, this part of the condensate is not easy to fall into the second air guide port 351, and the second air guide port 351 is not easy to be blocked, thereby avoiding the problem of external gas being unable to enter the atomization cavity 31.

[0050] The atomizer 100 is further described below with reference to the accompanying drawings.

[0051] See also Figures 2 to 4 In some embodiments, in a plane perpendicular to the length direction H of the atomizer 100 , the projection of the first air guide port 331 is located within the range of the projection of the air guide cavity 17 and is spaced from the projection of the storage cavity 15 .

[0052] Among them, during the user's inhalation process, the external gas entering from the first air guide port 331 can carry the aerosol in the atomization chamber 31 in the length direction H of the atomizer 100 through the air guide chamber 17 and flow out to the outside of the atomizer 100. In the process of carrying the aerosol flow, the external gas can try to avoid the aerosol from contacting the side wall of the bracket 30 and / or the side wall of the air guide chamber 17, so as to avoid the problem of the aerosol adhering to the side wall of the bracket 30 and / or the side wall of the air guide chamber 17 and condensing to form condensate. At this time, on the one hand, the deposition rate of the aerosol in the atomization chamber 31 can be reduced, the amount of aerosol inhaled by the user per unit time is large, and the user's inhalation experience is better. On the other hand, it can also try to avoid the condensate formed by the condensation of the aerosol from falling into the first air guide port 331 to block the first air guide port 331.

[0053] See also Figures 2 to 4 In some embodiments, in a plane perpendicular to the length direction H of the atomizer 100, the projection of the second air guide port 351 is located within the range of the projection of the storage cavity 15. In the length direction H of the atomizer 100, the second air guide port 351 is directly opposite to the bottom wall 16 of the storage cavity 15. The upper end of the second air guide port 351 is separated from the bottom wall 16 of the storage cavity 15 to form an air gap 353. The second air guide port 351 is connected to the atomization cavity 31 through the air gap 353.

[0054] At this time, when the aerosol adheres to the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 and forms condensate, in the case where the condensate falls, the bottom wall 16 of the storage cavity 15 can prevent the condensate from falling into the second air guide port 351. At the same time, in the length direction H of the atomizer 100, there is an air gap 353 between the bottom wall 16 of the storage cavity 15 and the second air guide port 351, and the bottom wall 16 of the storage cavity 15 will not block the second air guide port 351. During the user's inhalation, external gas enters the second air guide port 351 and passes through the air gap 353 into the atomization cavity 31. In the length direction H of the atomizer 100, the height of the air gap 353 is small, so that the condensate can be prevented from passing through the air gap 353 into the second air guide port 351, so as to further prevent the condensate from falling and blocking the second air guide port 351. When the atomizer 100 is placed vertically, the second air guide port 351 can remain unobstructed when the user inhales, so that external air can smoothly enter the atomization chamber 31, and the second air guide port 351 is not prone to blockage.

[0055] When the atomizer 100 is placed horizontally so that the air guide cavity 17 is on the top and the storage cavity 15 is on the bottom, a small amount of the aerosol generating matrix in the storage cavity 15 will flow into the atomizing cavity 31 from the ventilation channel 18, and part of the aerosol generating matrix in the storage cavity 15 will flow into the atomizing cavity 31 through the micropores of the heating element 50. The aerosol generating matrix entering the atomizing cavity 31 will accumulate near the second air guide port 351 due to gravity, which will cause the second air guide port 351 to be blocked. If there is only the second air guide port 351 in the atomizer 100, the external gas will not be able to enter the atomizing cavity 31 at this time. The present application is provided with a first air guide port 331 and a second air guide port 351. When the atomizer 100 is placed horizontally so that the air guide cavity 17 is on the top and the storage cavity 15 is on the bottom, in the length direction H perpendicular to the atomizer 100, the first air guide port 331 is on the top and the second air guide port 351 is on the bottom. At this time, even if the second air guide port 351 is blocked by the aerosol generating substrate, the first air guide port 331 can remain unobstructed, so that the external air can smoothly enter the atomizing chamber 31 .

[0056] See also Figures 2 to 4 , a first air guide port 331 and a second air guide port 351 are provided on the bottom wall of the atomizing chamber 31, and in a plane perpendicular to the length direction H of the atomizer 100, the projection of the first air guide port 331 is located within the range of the projection of the air guide chamber 17, and the projection of the second air guide port 351 is located within the range of the projection of the storage chamber 15. When the atomizer 100 is placed vertically, when the aerosol in the atomizing chamber 31 contacts the side wall of the bracket 30 and / or the side wall of the air guide chamber 17 and forms condensate, the condensate falls and easily blocks the first air guide port 331. At this time, the second air guide port 351 can remain unobstructed, so that external gas can smoothly enter the atomizing chamber 31. When the atomizer 100 is placed horizontally, the aerosol in the storage chamber 15 that enters the atomization chamber 31 from the micropores of the ventilation channel 18 and the heating element 50 generates a matrix that is easy to block the second air guide port 351. At this time, the first air guide port 331 can remain unobstructed, so that external gas can smoothly enter the atomization chamber 31. During the user's inhalation, external gas can enter the atomization chamber 31 through the first air guide port 331 and / or the second air guide port 351, and carry the aerosol in the atomization chamber 31 through the air guide chamber 17 to flow out of the atomizer 100, so that the user has a better inhalation experience.

[0057] See also Figures 2 to 4 In some embodiments, the first end 11 of the storage element 10 includes a mounting portion 111, the bracket 30 is connected to the mounting portion 111, and the bracket 30 and the mounting portion 111 together form an atomization chamber 31; in a plane perpendicular to the length direction H of the atomizer 100, the projection of the mounting portion 111 covers the projection of the second air guide port 351.

[0058] The mounting portion 111 of the present application is provided with a protrusion, the bracket 30 is provided with a groove 36, and the mounting portion 111 is detachably connected to the bracket 30. The heating element 50 and the first sealing member 51 are both mounted on the mounting portion 111. The bottom wall 16 of the storage cavity 15 of the present application is a partial structure of the mounting portion 111. In a plane perpendicular to the length direction H of the atomizer 100, when the projection of the mounting portion 111 covers the projection of the second air guide port 351, the second air guide port 351 corresponds to the partial structure of the mounting portion 111 and is spaced to form an air gap 353. When the condensate formed by the aerosol adhering to the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 falls, the mounting portion 111 can prevent the condensate from falling into the second air guide port 351. Preferably, in the length direction H of the atomizer 100, the gap between the part of the mounting portion 111 and the second air guide port 351 is small (the size of the air gap 353 in the height direction is small), so that the condensate can be prevented from entering the second air guide port 351 through the air gap 353, so as to further prevent the condensate from falling and clogging the second air guide port 351. During the user's inhalation process, the second air guide port 351 can remain unobstructed, so that external gas can smoothly enter the atomization chamber 31.

[0059] See also Figures 2 to 5 Furthermore, in some embodiments, the bracket 30 includes a first air guide portion 33, which extends from the bottom wall of the atomization chamber 31 toward the storage element 10, and the first air guide port 331 passes through the bottom wall of the atomization chamber 31 and the first air guide portion 33.

[0060] Among them, the first air guide portion 33 is used to guide external gas into the atomizing chamber 31. The first air guide portion 33 and the bottom wall of the atomizing chamber 31 can be an integral structure or a split structure. In the case where the first air guide portion 33 and the bottom wall of the atomizing chamber 31 are an integral structure, the first air guide portion 33 and the bottom wall of the atomizing chamber 31 can be integrally formed. At this time, the processing steps of the bracket 30 are relatively simple. In the case where the first air guide portion 33 and the bottom wall of the atomizing chamber 31 are a split structure, the first air guide portion 33 and the bottom wall of the atomizing chamber 31 are 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.

[0061] The aerosol-generating substrate that flows from the storage chamber 15 through the ventilation channel 18 and the micropores of the heating element 50 into the atomizing chamber 31 will gather at the bottom of the atomizing chamber 31. In the height direction of the atomizer 100, the highest point of the first air guide portion 33 is at least higher than the bottom wall of the atomizing chamber 31. At this time, the first air guide portion 33 can block the aerosol-generating substrate at the bottom of the atomizing chamber 31 from entering the first air guide port 331, thereby preventing the aerosol-generating substrate from blocking the first air guide port 331.

[0062] See also Figures 2 to 5 Furthermore, in some embodiments, the bracket 30 includes a second air guide portion 35, which extends from the bottom wall of the atomization chamber 31 toward the storage element 10, and the second air guide port 351 passes through the bottom wall of the atomization chamber 31 and the second air guide portion 35.

[0063] Among them, the second air guide portion 35 is used to guide external gas into the atomizing chamber 31. The second air guide portion 35 and the bottom wall of the atomizing chamber 31 can be an integral structure or a split structure. In the case where the second air guide portion 35 and the bottom wall of the atomizing chamber 31 are an integral structure, the second air guide portion 35 and the bottom wall of the atomizing chamber 31 can be integrally formed. At this time, the processing steps of the bracket 30 are relatively simple. In the case where the second air guide portion 35 and the bottom wall of the atomizing chamber 31 are a split structure, the second air guide portion 35 and the bottom wall of the atomizing chamber 31 are 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.

[0064] The aerosol-generating substrate that flows from the storage chamber 15 through the ventilation channel 18 and the micropores of the heating element 50 into the atomizing chamber 31 will gather at the bottom of the atomizing chamber 31. In the height direction of the atomizer 100, the highest point of the second air guide portion 35 is at least higher than the bottom wall of the atomizing chamber 31. At this time, the second air guide portion 35 can block the aerosol-generating substrate at the bottom of the atomizing chamber 31 from entering the second air guide port 351, thereby preventing the aerosol-generating substrate from blocking the second air guide port 351.

[0065] See also Figure 4 and Figure 5 In some embodiments, the bottom wall of the atomization chamber 31 is provided with at least one capillary groove. The number of capillary grooves may be, but is not limited to, one, two, three, four or more. Preferably, capillary grooves may be provided at other positions of the bottom wall of the atomization chamber 31 except the first air guide portion 33 and the second air guide portion 35. After the aerosol generating matrix gathered at the bottom of the atomization chamber 31 enters the capillary groove, the aerosol generating matrix may be locked in the capillary groove due to the capillary action and the surface tension of the liquid, and the aerosol generating matrix in the capillary groove will not flow or move at will, thereby further avoiding the aerosol generating matrix in the atomization chamber 31 from flowing into the first air guide port 331 and / or the second air guide port 351 to block the first air guide port 331 and / or the second air guide port 351.

[0066] See also Figure 4 and Figure 5In other embodiments, the bottom wall of the atomizing chamber 31 is provided with at least one groove 36, and the bottom of the groove 36 is provided with at least one capillary groove. The number of the grooves 36 at the bottom of the atomizing chamber 31 may be, but is not limited to, one, two, three, four or more. Preferably, grooves 36 may be provided at other positions of the bottom wall of the atomizing chamber 31 except the first air guide portion 33 and the second air guide portion 35. The number of capillary grooves provided in the groove 36 may be, but is not limited to, one, two, three, four or more. After the aerosol generating substrate gathered at the bottom of the atomizing chamber 31 enters the groove 36, the aerosol generating substrate will be locked by the capillary groove in the groove 36, so that the aerosol generating substrate at the bottom of the atomizing chamber 31 will not flow or move at will, and the aerosol generating substrate in the atomizing chamber 31 can be further prevented from flowing into the first air guide port 331 and / or the second air guide port 351 to block the first air guide port 331 and / or the second air guide port 351.

[0067] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the atomizer 100 further includes a first electrical connector 40 and a second electrical connector 60. The first electrical connector 40 is mounted on the bracket 30 and extends into the atomization chamber 31. The first electrical connector 40 is electrically connected to an electrode of the heating film on the heating element 50.

[0068] Specifically, the second electrical connector 60 is electrically connected to the first electrical connector 40 and the battery assembly 300. The second electrical connector 60 is used to transfer the electrical energy of the battery assembly 300 to the first electrical connector 40. The first electrical connector 40 is electrically connected to an electrode (positive or negative) of the heating film of the heating element 50, so that the electrical energy of the battery assembly 300 is transferred to an electrode (positive or negative) of the heating film of the heating element 50 through the second electrical connector 60 and the first electrical connector 40.

[0069] The air passage 61 is connected to the sub-holes 63. The number of sub-holes 63 may be, but is not limited to, two, three, four or more. The number of sub-holes 63 in the present application is two, and the two sub-holes 63 correspond to the first air guide port 331 and the second air guide port 351, respectively. When the user inhales, external gas enters the aerosol generating device 1000 from the battery assembly 300. The gas enters the air passage 61 from the battery assembly 300, passes through the two sub-holes 63, and enters the atomizing chamber 31 from the first air guide port 331 and the second air guide port 351. The gas carries the aerosol in the atomizing chamber 31 and flows out of the air guide chamber 17 to the outside of the aerosol generating device 1000 for the user to inhale.

[0070] See also Figure 3 , Figure 4 and Figure 6 In some embodiments, the bracket 30 includes a bracket body 37 and a spacer 39, the bracket body 37 is connected to the mounting portion 111, the spacer 39 extends from an end of the bracket body 37 away from the storage element 10, and is located outside the atomization chamber 31; the spacer 39 is provided with a first air inlet 391 and a second air inlet 393, the atomizer 100 also includes a sleeve 80, the sleeve 80 is connected to the bracket body 37 and surrounds the spacer 39, the spacer 39 is located between the sleeve 80 and the second electrical connector 60, the first air inlet 391 is connected to one of the sub-holes 63 and the first air guide port 331, and the second air inlet 393 is connected to the other sub-hole 63 and the second air guide port 351.

[0071] Among them, the sleeve 80 is sleeved outside the bracket 30 and the mounting portion 111, and the sleeve 80 is used to support and fasten the bracket 30 and the mounting portion 111. The sleeve 80 of the present application is made of a conductive material, one end of the sleeve 80 is connected to the bracket body 37, and the other end of the sleeve 80 is electrically connected to the battery assembly 300, and the sleeve 80 is used to conduct the electrical energy of the battery assembly 300. Among them, the conductive material includes but is not limited to conductive metal materials and conductive carbon materials. 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 sleeve 80 is also used to connect the atomizer 100 to the battery assembly 300, and one end of the sleeve 80 connected to the battery assembly 300 is provided with a thread, and the sleeve 80 is connected to the battery assembly 300 by a thread to firmly connect the battery assembly 300 to the atomizer 100.

[0072] Since the second electrical connector 60 and the sleeve 80 are both made of conductive materials, the spacer 39 is used to space the second electrical connector 60 from the sleeve 80. The spacer 39 is made of non-conductive material, thereby avoiding the problem of short circuit between the second electrical connector 60 and the sleeve 80.

[0073] When the user inhales, external gas enters the aerosol generating device 1000 from the battery assembly 300, and the gas enters the air channel 61 from the battery assembly 300. The gas in the air channel 61 flows out from the two sub-holes 63 respectively, and enters the atomizing chamber 31 from the first air guide port 331 through the first air inlet 391, and enters the atomizing chamber 31 from the second air guide port 351 through the second air inlet 393. The gas carries the aerosol in the atomizing chamber 31 and flows out of the air guide chamber 17 to the outside of the aerosol generating device 1000 for the user to inhale.

[0074] See also Figures 2 to 4 In some embodiments, the atomizer 100 further includes a first decorative member 19, which is sleeved at the connection between the first end 11 of the storage member 10, the bracket body 37 and the sleeve 80. The first decorative member 19 is used to cover the connection between the first end 11 of the storage member 10, the bracket body 37 and the sleeve 80 to enhance the aesthetics of the atomizer 100. The first decorative member 19 of the present application is made of a metal material to further enhance the aesthetics of the atomizer 100. The first decorative member 19 can also further tighten the first end 11 of the storage member 10, the bracket body 37 and the sleeve 80 to avoid the problem of loose connection between the first end 11 of the storage member 10, the bracket body 37 and the sleeve 80.

[0075] See also Figure 5 and Figure 6 In some embodiments, the atomizer 100 further includes a third electrical connector 70 . The third electrical connector 70 passes through the bracket 30 , one end of the third electrical connector 70 is electrically connected to the sleeve 80 , and the other end is electrically connected to another electrode of the heating film on the heating element 50 .

[0076] Among them, the third electrical connector 70 is fixedly installed on the bracket 30, and the third electrical connector 70 is used to electrically connect the sleeve 80 with one electrode of the heating film of the heating element 50. Since the sleeve 80 is electrically connected to the battery assembly 300, the third electrical connector 70 is electrically connected to the sleeve 80 and one electrode of the heating film of the heating element 50, so that the battery assembly 300 can be electrically connected to one electrode of the heating film of the heating element 50. When the first electrical connector 40 is electrically connected to the positive electrode of the heating film, the third electrical connector 70 is electrically connected to the negative electrode of the heating film, so that the heating element 50 can be electrically connected to the battery assembly 300, and the battery assembly 300 can supply power to the heating element 50. When the first electrical connector 40 is electrically connected to the negative electrode of the heating film, the third electrical connector 70 is electrically connected to the positive electrode of the heating film, so that the heating element 50 can be electrically connected to the battery assembly 300, and the battery assembly 300 can supply power to the heating element 50.

[0078] Specifically, the nozzle 90 is detachably connected to the second end 13 of the storage element 10. When the user uses the aerosol generating device 1000, the battery assembly 300 supplies power to the atomizer 100, and the user inhales the aerosol generated in the atomizer 100 through the nozzle 90. The nozzle 90 is provided with a through hole 95, and the through hole 95 is connected to the air guide cavity 17. When the user inhales, external gas enters the aerosol generating device 1000 from the battery assembly 300, and the gas enters the airway 61 from the battery assembly 300. The gas in the airway 61 flows out from the two sub-holes 63 respectively, and flows to the first air guide port 331 through the first air inlet 391, and flows to the second air guide port 351 through the second air inlet 393. The gas in the first air guide port 331 and the gas in the second air guide port 351 enter the atomization cavity 31. The aerosol in the atomization chamber 31 carried by the gas flows from the gas guide chamber 17 into the through hole 95 , and flows out of the aerosol generating device 1000 from the through hole 95 for the user to inhale.

[0079] The second sealing member 91 is used to prevent aerosol from flowing out of the gap between the mouthpiece 90 and the second end 13 of the storage member 10 into the storage chamber 15 or even out of the atomizer 100. The second sealing member 91 can also prevent the aerosol-generating matrix in the storage chamber 15 from flowing into the air guide chamber 17 and the through hole 95. The second sealing member 91 can also seal the gap between the air guide chamber 17 and the through hole 95, and when the user draws, the suction resistance between the air guide chamber 17 and the through hole 95 can be reduced. The second sealing member 91 can be made of materials such as rubber, silicone, plastic or synthetic fiber.

[0080] See also Figure 2 and Figure 3 The atomizer 100 may further include a second decorative piece 93, which is sleeved at the connection between the suction nozzle 90 and the second end 13 of the storage element 10.

The second decorative piece 93 of the present application is made of a metal material to further enhance the aesthetics of the atomizer 100. The second decorative piece 93 is interference fit with the suction nozzle 90 and the second end 13 of the storage element 10, thereby further tightening the second end 13 of the storage element 10 and the suction nozzle 90 to avoid the problem of looseness between the second end 13 of the storage element 10 and the suction nozzle 90.

[0081] In the aerosol generating device 1000 of the embodiment of the present application, in a plane perpendicular to the length direction H of the atomizer 100, the projection of the first air guide port 331 at least partially overlaps with the projection of the air guide cavity 17, and the projection of the second air guide port 351 is spaced from the projection of the air guide cavity 17. During the user's inhalation process, the first air guide port 331 allows external gas to enter the atomization cavity 31, and this part of the gas carries the aerosol in the atomization cavity 31 and flows out of the air guide cavity 17 and is inhaled by the user. The first air guide port 331 can minimize the problem of aerosol contacting the side wall of the bracket 30 and / or the side wall of the air guide cavity 17 and condensing. The second air guide port 351 allows external gas to enter the atomization cavity 31. In the case where the condensate formed by the aerosol falls, this part of the condensate is not easy to fall into the second air guide port 351, and the second air guide port 351 is not easy to be blocked, thereby avoiding the problem that the external gas cannot enter the atomization cavity 31.
