[0038] In order to avoid the problem of aerosol generating matrix leaking and clogging the pores, the current aerosol generating device is usually equipped with an oil storage tank and a ventilation channel. The oil storage tank is used to store the aerosol generating matrix leaking from the oil storage tank, and the ventilation channel can reabsorb the aerosol generating matrix in the oil storage tank. However, due to the high viscosity of the aerosol generating matrix, it is difficult for the aerosol generating matrix to be reabsorbed into the oil storage tank through the ventilation channel. The aerosol generating matrix is ​​lacking in the oil storage tank, and the heating element is prone to scorching when heated. In order to solve this problem, the embodiment of the present application provides an atomizer 100( Figure 1 aerosol generating device 1000 (shown) Fig.10 shown).

[0039] See also Figures 1 to 4 The atomizer 100 of the embodiment of the present application includes a storage element 10, a bracket 30, a heating element 40 and a recovery assembly 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 a first airway 17 spaced apart from each other, and the storage cavity 15 is used to store an aerosol generating substrate. The bracket 30 is connected to the first end 11 of the storage element 10, and the bracket 30 and the storage element 10 together form an atomizing cavity 31, and the atomizing cavity 31 is connected to the first airway 17. The heating element 40 is installed on the storage element 10 and is located in the atomizing cavity 31. The heating element 40 is used to heat the aerosol generating substrate in the storage cavity 15 to generate an aerosol, and the first airway 17 is used to allow the aerosol to flow out. The recovery component 50 is installed on the bracket 30 and extends from the atomization chamber 31 into the storage chamber 15. The part of the recovery component 50 located in the atomization chamber 31 is provided with a recovery channel 51. The recovery channel 51 is connected to both the atomization chamber 31 and the storage chamber 15. The recovery component 50 is located within a preset distance range of the heating element 40 so as to receive the heat emitted by the heating element 40.

[0040] Please combine Fig.10 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.

[0041] 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.

[0042] 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 40, so that the heating element 40 can generate heat to heat the aerosol generating substrate.

[0043] See also Figure 2 and Figure 3 The 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. The storage element 10 includes a body and a partition. The body may be a columnar structure. The partition is installed in the body and divides the cavity of the body into a storage cavity 15 and a first airway 17 that are not connected to each other. The body and the partition may be an integral structure or a split structure. In the case where the body and the partition are an integral structure, the body and the partition may be integrally formed, and the processing steps of the storage element 10 are relatively simple. In the case where the body and the partition are a split structure, the partition may be detachably or non-detachably connected to the body. Among them, detachable installation methods include but are not limited to threaded connection, screw connection or snap connection, etc. Non-detachable installation methods include but are not limited to welding, gluing connection or interference fit, etc.

[0044] The storage chamber 15 is used to store the aerosol generating substrate therein, and the first air channel 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 first air channel 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.

[0045] See also Figures 2 to 4, the bracket 30 is a structure for installing the recovery assembly 50 and other elements of the atomizer 100. 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, and the protrusion cooperates with the groove, 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, and the bracket 30 is provided with a protrusion, and the groove 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. The number of protrusions may be one, two, three or more, and the number of grooves is the same as the number of protrusions. The number of grooves of the present application is two, and the two grooves 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 respectively.

[0046] The support 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 40 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 first airway 17 and be inhaled by the user.

[0047] See also Figures 2 to 4 The heating element 40 is a structure that can generate heat when powered. When the battery assembly 300 supplies power to the heating element 40, the heating element 40 can generate heat to heat the aerosol generating matrix located near the heating element 40, and the heated aerosol generating matrix can generate aerosol. The heating element 40 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 40 is installed at the first end 11 of the storage element 10. The heating element 40 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 40 and enter the porous ceramic through the micropores. When the heating element 40 generates heat, the aerosol generating matrix that contacts the heating element 40 and enters the micropores will be heated to generate aerosol. The generated aerosol enters the atomizing chamber 31 and enters the first air passage 17 from the atomizing chamber 31 . The aerosol flows out of the atomizer 100 from the first air passage 17 to be inhaled by the user.

[0048] See also Figures 2 to 4, the atomizer 100 also includes a first seal 41, which is arranged around the heating element 40, and the first seal 41 is used to seal the gap between the heating element 40 and the first end 11 of the storage element 10. The first seal 41 can be made of materials such as rubber, silicone, plastic or synthetic fiber. The number of the first seals 41 of the present application is two. When the number of the first seals 41 is two, the sealing effect of the first seal 41 is better. The first seal 41 can prevent the aerosol-generating matrix in the storage chamber 15 from entering the atomization chamber 31 from the gap between the heating element 40 and the first end 11 of the storage element 10, and leaking from the airway port 33 or even blocking the airway port 33. When the airway port 33 is blocked, when the user inhales, the outside gas cannot enter the atomization chamber 31, and the outside gas cannot carry the aerosol out of the first channel.

[0049] See also Figures 2 to 4 , the aerosol generating matrix in the storage chamber 15 is due to gravity, or the gas in the storage chamber 15 is heated and expanded to squeeze the aerosol generating matrix, and part of the aerosol generating matrix in the storage chamber 15 will enter the atomizing chamber 31 from the microporous structure of the heating element 40. Part of the aerosol in the atomizing chamber 31 may also form a condensate, that is, the condensed aerosol may liquefy to form an aerosol generating matrix. The recovery component 50 is used to recover the aerosol generating matrix in the atomizing chamber 31. The recovery component 50 can recover the aerosol generating matrix in the atomizing chamber 31 to the storage chamber 15 to avoid the aerosol generating matrix in the atomizing chamber 31 blocking the airway opening 33, and also avoid the waste of the aerosol generating matrix. The recovery channel 51 is used for the aerosol generating matrix in the atomizing chamber 31 to flow therein. When the air pressure in the storage chamber 15 is reduced, the aerosol generating matrix in the atomizing chamber 31 enters the recovery channel 51 and flows into the storage chamber 15 from the recovery channel 51. The recovery component 50 is mounted on the bracket 30, and the recovery component 50 is located in the atomization chamber 31 and extends into the storage chamber 15, so that the recovery component 50 can recover the aerosol generating substrate in the atomization chamber 31 to the storage chamber 15. The aerosol generating substrate recovered in the storage chamber 15 flows to the vicinity of the heating element 40, and is heated by the heating element 40 to form an aerosol for the user to inhale. There is always an aerosol generating substrate near the heating element 40, so that the heating element 40 will not have the problem of dry burning and burning.

[0050] The preset distance range refers to the distance at which the recovery component 50 can receive the heat emitted by the heating element 40. Exemplarily, the preset distance range may be [0, A]. When the recovery component 50 is within the preset distance range [0, A] of the heating element 40, the recovery component 50 can be heated by the heating element 40, the aerosol generating substrate in the recovery channel 51 can be heated by the recovery component 50, and the viscosity of the heated aerosol generating substrate is small, and the fluidity of the aerosol generating substrate is good, so that the aerosol generating substrate in the recovery channel 51 can flow into the storage chamber 15 more easily. When the preset distance range between the recovery component 50 and the heating element 40 is greater than the A value, the recovery component 50 cannot receive the heat from the heating element 40, or the heat from the heating element 40 received by the recovery component 50 is too little, and at this time, the heating of the aerosol generating substrate by the recovery component 50 cannot effectively reduce the viscosity of the aerosol generating substrate.

[0051] In the atomizer 100 of the embodiment of the present application, the storage element 10 and the bracket 30 form an atomization chamber 31, the heating element 40 is located in the atomization chamber 31, and the recovery assembly 50 is located in the atomization chamber 31 and extends into the storage chamber 15. The recovery assembly 50 is located within a preset distance range of the heating element 40, and the aerosol generating substrate in the recovery assembly 50 can be heated by the heating element 40. The viscosity of the heated aerosol generating substrate becomes smaller, and the aerosol generating substrate in the recovery assembly 50 can flow into the storage chamber 15 more easily. There will be no problem of lack of aerosol generating substrate in the storage chamber 15, so that the problem of burning will not occur when the heating element 40 is heated.

[0052] The atomizer 100 is further described below with reference to the accompanying drawings.

[0053] See also Figures 3 to 6 In some embodiments, the recovery component 50 is in direct or indirect contact with the heating element 40. In the case where the recovery component 50 is in direct or indirect contact with the heating element 40, the recovery component 50 can effectively absorb the heat of the heating element 40, so that the heating temperature of the aerosol generating substrate in the recovery channel 51 by the recovery component 50 is relatively high. The higher the temperature of the aerosol generating substrate, the lower the viscosity of the aerosol generating substrate, and the easier it is for the aerosol generating substrate in the recovery channel 51 to flow into the storage chamber 15.

[0054] In one embodiment, the recovery component 50 is in direct contact with the heating element 40. At this time, the heat of the heating element 40 is directly transferred to the recovery component 50 by solid heat transfer, and the heat loss from the heating element 40 to the recovery component 50 is small, so that the temperature of the recovery component 50 is high. The recovery component 50 can quickly heat the aerosol generating substrate in the recovery channel 51, and the viscosity of the aerosol generating substrate is small. When the air pressure in the storage chamber 15 is reduced, the aerosol generating substrate can flow smoothly into the storage chamber 15.

[0055] In another embodiment, the recovery component 50 is in indirect contact with the heating element 40. In this case, a connector may be provided between the recovery component 50 and the heating element 40. The connector is connected to both the heating element 40 and the recovery component 50, and the thermal conductivity of the connector is good, so that the connector can effectively transfer the heat of the heating element 40 to the recovery component 50. The materials of the connector include but are not limited to metal materials, carbon materials, ceramic materials and polymer materials with good thermal conductivity. Among them, metal materials with good thermal conductivity include copper, aluminum, iron and magnesium, etc., carbon materials with good thermal conductivity include graphene, carbon nanotubes and carbon fibers, etc., ceramic materials with good thermal conductivity include alumina ceramics and silicon nitride ceramics, etc., and carbon materials with good thermal conductivity include polyimide and polyetheretherketone, etc.

[0056] See also Figures 3 to 6 , further, in some embodiments, the recycling component 50 is conductive and electrically connected to an electrode of the heating film on the heating element 40. Specifically, when the recycling component 50 is in contact with the heating element 40, the recycling component 50 can also be electrically connected to the heating element 40. In one embodiment, the recycling component 50 can be electrically connected to the positive electrode on the heating film of the heating element 40. The recycling component 50 is electrically connected to the positive electrode of the heating element 40 and the second electrical connector 70 of the atomizing chamber 31, and the second electrical connector 70 of the atomizing chamber 31 is electrically connected to the battery assembly 300, so that the positive electrode of the heating element 40 can be electrically connected to the battery assembly 300. In another embodiment, the recycling component 50 can be electrically connected to the negative electrode on the heating film of the heating element 40. The recycling component 50 is electrically connected to the negative electrode of the heating element 40 and the second electrical connector 70 of the atomizing chamber 31, so that the negative electrode of the heating element 40 can be electrically connected to the battery assembly 300.

[0057] When the user inhales, the battery assembly 300 supplies power to the heating element 40 through the recovery assembly 50, and the heating element 40 generates heat and can heat the recovery assembly 50. The recovery assembly 50 integrates the functions of recovery and conduction, so that the atomizer 100 can have fewer components, which can save the cost of the atomizer 100, and the processing of the atomizer 100 is also relatively simple.

[0058] In one embodiment, the heating element 40 can be placed in the atomization chamber 31, that is, the width W of the heating element 40 is perpendicular to the length L of the atomizer 100. At this time, the heating film of the heating element 40 faces the bottom of the atomization chamber 31. The recovery component 50 is electrically connected to the side where the heating film of the heating element 40 is located. In another embodiment, the heating element 40 can be placed sideways in the atomization chamber 31, that is, the width W of the heating element 40 is parallel to the length L of the atomizer 100, and the side where the heating film of the heating element 40 is located faces the side wall of the bracket 30. At this time, the contact area between the recovery component 50 and the side where the heating film of the heating element 40 is located is large, and the recovery component 50 can absorb more heat from the heating element 40, so that the aerosol generating matrix in the recovery channel 51 can be quickly heated, the viscosity of the aerosol generating matrix in the recovery channel 51 is small, and the aerosol generating matrix in the recovery channel 51 can flow into the storage chamber 15 more easily. The heating element 40 of the present application is placed sideways in the atomization chamber 31.

[0059] See also Figures 3 to 6 In some embodiments, the recovery component 50 includes a first electrical connector 53 and a guide 55. The first electrical connector 53 is mounted on the bracket 30 and is provided with a receiving chamber 531 communicating with the atomization chamber 31. The guide 55 is provided with a guide chamber 551 running through opposite ends, one end of the guide 55 is connected to the first electrical connector 53, and the other end of the guide 55 is connected to the storage element 10, the guide chamber 551 is communicated with both the receiving chamber 531 and the storage chamber 15, and the receiving chamber 531 and the guide chamber 551 together form a recovery channel 51.

[0060] Specifically, the first electrical connector 53 is used to be electrically connected to the second electrical connector of the atomizer 100. The accommodating cavity 531 is used to accommodate the aerosol generating substrate in the atomizing cavity 31, thereby avoiding the problem of the aerosol generating substrate in the atomizing cavity 31 blocking the airway opening 33. In the case where the first electrical connector 53 is provided with the accommodating cavity 531, the first electrical connector 53 integrates the functions of electrical connection and collection of aerosol generating substrate, thereby reducing the number of components used in the atomizer 100, and the structure of the atomizer 100 is relatively simple.

[0061] The guide member 55 is a structure for guiding the aerosol generating substrate in the accommodating chamber 531 to the storage chamber 15. The guide chamber 551 is used for the aerosol generating substrate in the accommodating chamber 531 to flow therethrough. The guide member 55 is located in the atomizing chamber 31 and at least partially extends into the storage chamber 15. One end of the guide member 55 extends into the accommodating chamber 531 and is connected to the inner wall of the first electrical connector 53. The connection method of the guide member 55 and the first connector may be, but is not limited to, threaded connection, interference fit, or adhesive connection. The other end of the guide member 55 is fixedly connected to the storage member 10. The connection method of the guide member 55 and the storage member 10 may be, but is not limited to, threaded connection, interference fit, or adhesive connection. The guide member 55 is fixedly connected to both the storage member 10 and the first electrical connector 53, so that the installation of the guide member 55 is relatively stable.

[0062] The guide member 55 is in contact with the side where the heating film of the heating element 40 is located, and the guide member 55 can be heated by the heating element 40, so that the aerosol generating substrate in the guide cavity 551 can be heated by the guide member 55, and the viscosity of the aerosol generating substrate in the guide cavity 551 is relatively low. When the guide member 55 is heated, the guide member 55 can transfer heat to the first electrical connector 53, so that the first electrical connector 53 can heat the aerosol generating substrate in the accommodating cavity 531, and the viscosity of the aerosol generating substrate in the heated accommodating cavity 531 is relatively low. When the air pressure in the storage cavity 15 is reduced, the aerosol generating substrate in the accommodating cavity 531 can flow smoothly into the guide cavity 551, and the aerosol generating substrate in the guide cavity 551 can flow smoothly into the storage cavity 15.

[0063] The guide member 55 is made of a conductive material. When the guide member 55 is in contact with the heating film of the heating element 40, the guide member 55 can be electrically connected to one electrode (positive electrode or negative electrode) of the heating film, thereby realizing electrical connection between the first electrical connector 53 and the heating element 40. Preferably, the guide member 55 needs to have good electrical conductivity and good thermal conductivity. The guide member 55 of the present application is made of stainless steel plated material.

[0064] See also Figure 3 , Figure 4 and Figure 7In some embodiments, a through hole 533 is provided at a position of the first electrical connector 53 near the bottom of the atomizing chamber 31, and the through hole 533 connects the atomizing chamber 31 and the accommodating chamber 531. The through hole 533 is used for the aerosol generating substrate in the atomizing chamber 31 to flow into the accommodating chamber 531. Due to the gravity of the aerosol generating substrate itself, the aerosol generating substrate in the atomizing chamber 31 will gather at the bottom of the atomizing chamber 31. In the case where the through hole 533 is located near the bottom of the atomizer 100, the aerosol generating substrate at the bottom of the atomizing chamber 31 can flow into the accommodating chamber 531 through the through hole 533, which can avoid the problem of the aerosol generating substrate in the atomizing chamber 31 blocking the airway opening 33. The opening shape of the through hole 533 can be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygons.

[0065] See also Figure 3 , Figure 4 , Figure 7 and Figure 8 Furthermore, in some embodiments, the atomizer 100 also includes a second electrical connector 70, which is connected to the first electrical connector 53 and is located outside the atomization chamber 31. The second electrical connector 70 is provided with a second air duct 71 and a branch hole 73. The bottom of the atomization chamber 31 is provided with a penetrating air duct opening 33, and the air duct opening 33 is connected to the second air duct 71 through the branch hole 73.

[0066] Specifically, the second electrical connector 70 is electrically connected to the first electrical connector 53 and the battery assembly 300. The second electrical connector 70 is used to transfer the electrical energy of the battery assembly 300 to the first electrical connector 53. The first electrical connector 53 is electrically connected to the guide member 55, so that the electrical energy of the battery assembly 300 is transferred to an electrode (positive electrode or negative electrode) of the heating film of the heating element 40 through the second electrical connector 70, the first electrical connector 53 and the guide member 55.

[0067] When the user inhales, external gas enters the aerosol generating device 1000 from the battery assembly 300. The gas enters the second air channel 71 from the battery assembly 300, passes through the sub-hole 73, and enters the atomizing chamber 31 from the air channel opening 33. The gas carries the aerosol in the atomizing chamber 31 and flows out of the aerosol generating device 1000 from the first air channel 17 for the user to inhale.

[0068] See also Figure 2 , Figure 7 and Fig. 9In some embodiments, the bracket 30 includes a bracket body 35 and a spacer 37, the bracket body 35 is connected to the first end 11 of the storage element 10, the spacer 37 extends from the end of the bracket body 35 away from the storage element 10, and is located outside the atomization chamber 31; the spacer 37 is provided with an air inlet 371, the atomizer 100 also includes a sleeve 90, the sleeve 90 is connected to the bracket body 35 and surrounds the spacer 37, the spacer 37 is located between the sleeve 90 and the second electrical connector 70, and the air inlet 371 is connected to both the sub-hole 73 and the airway opening 33.

[0069] Among them, the sleeve 90 is sleeved outside the first end 11 of the bracket 30 and the storage element 10, and the sleeve 90 is used to support and fasten the first end 11 of the bracket 30 and the storage element 10. The sleeve 90 of the present application is made of a conductive material, one end of the sleeve 90 is connected to the bracket body 35, and the other end of the sleeve 90 is electrically connected to the battery assembly 300, and the sleeve 90 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 90 is also used to connect the atomization chamber 31 to the battery assembly 300, and one end of the sleeve 90 connected to the battery assembly 300 is provided with a thread, and the sleeve 90 is connected to the battery assembly 300 by a thread to firmly connect the battery assembly 300 to the atomizer 100.

[0070] The support body 35 is used to install the recovery assembly 50 and other components of the atomizer 100. Since the second electrical connector 70 and the sleeve 90 are both made of conductive materials, the spacer 37 is used to space the second electrical connector 70 from the sleeve 90. The spacer 37 is made of non-conductive material, thereby avoiding the problem of short circuit between the second electrical connector 70 and the sleeve 90.

[0071] When the user inhales, the external air enters the aerosol generating device 1000 from the battery assembly 300, and the air enters the second air channel 71 from the battery assembly 300. The air in the second air channel 71 flows out from the sub-hole 73, and enters the atomizing chamber 31 from the air channel opening 33 through the air inlet 371. The air carries the aerosol in the atomizing chamber 31 and flows out of the aerosol generating device 1000 from the first air channel 17 for the user to inhale.

[0072] See also Figures 3 to 6The 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 35 and the sleeve 90. The first decorative member 19 is used to cover the connection between the first end 11 of the storage member 10, the bracket body 35 and the sleeve 90 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 35 and the sleeve 90 to avoid the problem of loose connection between the first end 11 of the storage member 10, the bracket body 35 and the sleeve 90.

[0073] See also Figure 3 , Figure 4 , Figure 7 and Figure 8 In some embodiments, the bracket 30 includes an air guide portion 39, which extends from the bottom of the atomization chamber 31 toward the direction close to the storage element 10 and surrounds the airway opening 33. The air guide portion 39 is provided with a third airway 391 passing through the opposite ends of the air guide portion 39. In the length L direction of the atomizer 100, the highest point of the air guide portion 39 is higher than the highest point of the through hole 533.

[0074] Among them, the air guide portion 39 is used to guide the gas near the airway opening 33 into the atomizing chamber 31, and the third airway 391 is connected to the second airway 71 through the airway opening 33, the air inlet 371 and the sub-hole 73. When the user inhales, the external gas enters the aerosol generating device 1000 from the battery assembly 300, and the gas enters the second airway 71 from the battery assembly 300. The gas in the second airway 71 flows out from the sub-hole 73 and flows to the airway opening 33 through the air inlet 371. The gas in the airway opening 33 enters the atomizing chamber 31 through the third airway 391. The gas carries the aerosol in the atomizing chamber 31 and flows out of the aerosol generating device 1000 from the first airway 17 for the user to inhale.

[0075] When the highest point of the air guide portion 39 is higher than the highest point of the through hole 533, most of the aerosol generating substrate at the bottom of the atomizing chamber 31 can enter the accommodating chamber 531 through the through hole 533. The aerosol generating substrate at the bottom of the atomizing chamber 31 is not easy to enter the air guide portion 39, thereby avoiding the problem of the aerosol generating substrate entering the third airway 391 to block the airway opening 33.

[0076] The air guide portion 39 and the bracket body 35 are an integral structure or a split structure. In the case where the air guide portion 39 and the bracket body 35 are an integral structure, the air guide portion 39 and the bracket body 35 can be integrally formed, and the processing steps of the bracket 30 are relatively simple. In the case where the air guide portion 39 and the bracket body 35 are a split structure, the air guide portion 39 can be detachably or non-detachably installed on the bracket body 35 for connection. 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.

[0078] Specifically, the suction nozzle 60 of the present application is connected to the second end 13 of the storage element 10 by a snap-fit ​​connection, so that the connection between the suction nozzle 60 and the second end 13 of the storage element 10 is relatively stable. 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 suction nozzle 60. The suction nozzle 60 is provided with a through hole 65, and the through hole 65 is connected to the first airway 17. When the user inhales, the external gas enters the aerosol generating device 1000 from the battery assembly 300, and the gas enters the second airway 71 from the battery assembly 300. The gas in the second airway 71 flows out from the sub-hole 73 and flows to the airway port 33 through the air inlet 371. The gas at the airway port 33 enters the atomizing chamber 31 through the third airway 391. The aerosol in the atomization chamber 31 carried by the gas flows from the first air passage 17 into the through hole 65 , and flows out of the aerosol generating device 1000 from the through hole 65 for inhalation by the user.

[0079] The second sealing member 61 is used to prevent the aerosol from flowing out of the gap between the mouthpiece 60 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 61 can also prevent the aerosol-generating matrix in the storage chamber 15 from flowing into the first air channel 17 and the through hole 65. The second sealing member 61 can also seal the gap between the first air channel 17 and the through hole 65, and when the user draws, the suction resistance between the first air channel 17 and the through hole 65 can be reduced. The second sealing member 61 can be made of materials such as rubber, silicone, plastic or synthetic fiber.

[0080] See also Figure 3 and Figure 5The atomizer 100 may further include a second decorative piece 63, which is sleeved at the connection between the suction nozzle 60 and the second end 13 of the storage element 10. The second decorative piece 63 is used to cover the connection position between the second end 13 of the storage element 10 and the suction nozzle 60 to enhance the aesthetics of the atomizer 100. The second decorative piece 63 of the present application is made of a metal material to further enhance the aesthetics of the atomizer 100. The second decorative piece 63 is interference fit with the suction nozzle 60 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 60 to avoid the problem of looseness between the second end 13 of the storage element 10 and the suction nozzle 60.

[0081] See also Figure 2 , Fig. 9 and Fig.10 Furthermore, in some embodiments, the atomizer 100 further includes a third electrical connector 80 . The third electrical connector 80 passes through the bracket 30 , one end of the third electrical connector 80 is electrically connected to the sleeve 90 , and the other end is electrically connected to another electrode of the heating film on the heating element 40 .

[0082] Among them, the third electrical connector 80 is fixedly installed on the bracket 30, and the third electrical connector 80 is used to electrically connect the sleeve 90 with one electrode of the heating film of the heating element 40. Since the sleeve 90 is electrically connected to the battery assembly 300, the third electrical connector 80 is electrically connected to the sleeve 90 and one electrode of the heating film of the heating element 40, so that the battery assembly 300 can be electrically connected to one electrode of the heating film of the heating element 40. When the guide member 55 is electrically connected to the positive electrode of the heating film, the third electrical connector 80 is electrically connected to the negative electrode of the heating film, so that the heating element 40 can be electrically connected to the battery assembly 300, and the battery assembly 300 can supply power to the heating element 40. When the guide member 55 is electrically connected to the negative electrode of the heating film, the third electrical connector 80 is electrically connected to the positive electrode of the heating film, so that the heating element 40 can be electrically connected to the battery assembly 300, and the battery assembly 300 can supply power to the heating element 40.

[0083] In the aerosol generating device 1000 of the embodiment of the present application, the storage element 10 and the bracket 30 form an atomizing chamber 31, the heating element 40 is located in the atomizing chamber 31, and the recovery component 50 is located in the atomizing chamber 31 and extends into the storage chamber 15. The recovery component 50 is located within a preset distance range of the heating element 40, and the aerosol generating substrate in the recovery component 50 can be heated by the heating element 40. The viscosity of the heated aerosol generating substrate becomes smaller, and the aerosol generating substrate in the recovery component 50 can flow into the storage chamber 15 more easily. There will be no problem of lack of aerosol generating substrate in the storage chamber 15, so that the problem of burning will not occur when the heating element 40 is heated.
