Currently, most aerosol generating devices use a side atomization method, that is, a small oil tank is provided on the side of the heating element. The aerosol generating matrix in the oil storage tank flows into the small oil tank and is then heated by the heating element to generate aerosol. However, during the user's inhalation process, if the aerosol generating device is placed horizontally, the aerosol generating matrix in the small oil tank will flow back into the oil storage tank. The small oil tank is short of oil, while the heating element continues to heat, which will cause the aerosol to burn. Summary of the Invention

[0027] An aerosol generating device is a small device that can use the heat not burn (Heat Not Burning, HNB) technology to act on aerosol generating products and generate aerosols. Currently, most aerosol generating devices adopt a side atomization method, that is, a small oil tank is provided on the side of the heating element, and the aerosol generating matrix in the oil storage tank flows into the small oil tank, and is then heated by the heating element to generate an aerosol. However, during the user's inhalation process, if the aerosol generating device is placed horizontally, the aerosol generating matrix in the small oil tank will flow back into the oil storage tank, and the small oil tank will lack oil, which will cause the problem of burning. In order to solve this problem, the embodiment of the present application provides an atomizer 100 (shown in Figure 1) and an aerosol generating device 1000 (shown in Figure 9).

[0028] Referring to Figures 1 to 3, the atomizer 100 of the embodiment of the present application includes an atomizer seat 10, a heating element 90, an air guide 30, a liquid storage element 50, and a locking element 70. The heating element 90 is mounted on the atomizer seat 10. The air guide 30 is connected to the atomizer seat 10 and includes a first sub-section 31 and a second sub-section 33 that are connected. The atomizer seat 10 and the first sub-section 31 form a first liquid storage chamber 111, and at least a portion of the heating element 90 is located in the first liquid storage chamber 111. The liquid storage element 50 is arranged around the air guide 30. The liquid storage element 50 and the second sub-section 33 form a second liquid storage chamber 51, and the second liquid storage chamber 51 is connected to the first liquid storage chamber 111. The locking member 70 is provided in the first liquid storage chamber 111 and / or the second liquid storage chamber 51. The locking member 70 is used to prevent the aerosol-generating substrate in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51, and to guide the aerosol-generating substrate in the second liquid storage chamber 51 into the first liquid storage chamber 111.

[0029] Specifically, referring to FIG9 , the atomizer 100 of the present application is disposed within an aerosol generating device 1000 and is configured to be electrically powered to heat an aerosol-generating substrate, thereby generating an aerosol for inhalation by the user. The atomizer 100 may heat the aerosol-generating substrate by, but is not limited to, resistive heating, microwave heating, or laser irradiation heating.

[0030] The aerosol generating device 1000 is a structure capable of generating an aerosol by heating an aerosol generating matrix. The aerosol may 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) and liquid droplets of gas and condensed vapor. The aerosol generating matrix is ​​a product that has been processed and heated to generate an aerosol. The form of the aerosol generating matrix may be liquid, fully solid, or semi-solid. In the case where the aerosol generating matrix is ​​liquid, the liquid aerosol generating matrix is ​​a mixed liquid in which substances such as nicotine and nicotine are dissolved, and its solutes are common organic solutes and / or inorganic solutes such as propylene glycol, vegetable glycerin, and pure water. In the present application, the aerosol generating matrix may be a high-viscosity tobacco oil (e.g., sesame oil, etc.), which can generate an aerosol when heated.

[0031] Please refer to Figures 2 to 4. The atomizer seat 10 is a structure for installing the heating element 90 and other components. The aerosol generating matrix flows into the vicinity of the atomizer seat 10 and is heated by the heating element 90, thereby forming an aerosol for the user to inhale. The heating element 90 is a structure that can generate heat when powered. The heating element 90 generates heat to heat the aerosol generating matrix located near the heating element 90, and the heated aerosol generating matrix can generate aerosol. The heating element 90 can be a porous ceramic material. Porous ceramics are usually prepared by mixing ceramic slurry with a pore-forming agent and then sintering. The sintered ceramic body has a large number of micropores. The aerosol generating matrix in the first liquid storage chamber 111 can enter the interior of the porous ceramic through the micropores. When the heating element 90 generates heat, the aerosol generating matrix that contacts the heating element 90 and enters the micropores will be heated to generate aerosol.

[0032] Referring to Figure 5 , the air guide 30 is used to direct the generated aerosol to the exterior of the aerosol generating device 1000 for inhalation by the user. Preferably, the air guide 30 is made of a high-temperature resistant material. For example, the air guide 30 can be made of metal or ceramic, allowing it to guide high-temperature aerosols and extending its service life.

[0033] In the height direction of the aerosol generating device 1000, the second sub-section 33 is located above the first sub-section 31. The first sub-section 31 and the second sub-section 33 can be an integral structure. In this case, the first sub-section 31 and the second sub-section 33 can be integrally formed, and the processing steps of the air guide 30 are relatively simple. The first sub-section 31 and the second sub-section 33 can also be a separate structure. In this case, the first sub-section 31 and the second sub-section 33 are connected detachably or non-detachably. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit. In the case of a detachable connection between the first sub-section 31 and the second sub-section 33, if the first sub-section 31 (or the second sub-section 33) is damaged, it is only necessary to replace the first sub-section 31 (or the second sub-section 33), thereby extending the service life of the air guide 30.

[0034] A notch 315 is further provided on one side of the first sub-section 31 close to the second sub-section 33, and the notch 315 is used to connect the first liquid storage chamber 111 and the second liquid storage chamber 51. The atomization method of the nebulizer 100 of the present application is side atomization. The nebulizer 100 of side atomization has a simple structure. And during side atomization, the aerosol generating matrix is ​​not easy to clog the air inlet 13 of the nebulizer 100. The aerosol generated by side atomization is also relatively fine, and the user's inhalation taste is better. In the case of the nebulizer 100 of side atomization, the first liquid storage chamber 111 is located on one side of the heating element 90, and the notch 315 of the first sub-section 31 is opened on the side of the first sub-section 31 corresponding to the first liquid storage chamber 111, so that the aerosol generating matrix in the second liquid storage chamber 51 can enter the first liquid storage chamber 111 from the notch 315 and contact at least part of the heating element 90.

[0035] Referring to Figures 2 to 4 , the liquid reservoir 50 is a structure for storing an aerosol-generating substrate. The cross-sectional shape of the liquid reservoir 50 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal. The cross-sectional area of ​​the liquid reservoir 50 is at least larger than the maximum cross-sectional area of ​​the air guide 30, allowing the liquid reservoir 50 to be nested within the air guide 30.

[0036] The gap between the liquid storage member 50 and the outer peripheral wall of the second subsection 33 of the air guide 30 forms a second liquid storage chamber 51 for storing the aerosol-generating substrate. The atomizer base 10 and the inner wall of the second subsection 33 define a first liquid storage chamber 111, which stores the aerosol-generating substrate flowing from the second liquid storage chamber 51. The aerosol-generating substrate stored in the first liquid storage chamber 111 enters the micropores of the heating element 90, where it is heated to form an aerosol.

[0037] 2 to 4 , the locking member 70 can be used alone to prevent the aerosol-generating substrate in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51, and to guide the aerosol-generating substrate in the second liquid storage chamber 51 into the first liquid storage chamber 111. The locking member 70 can also be used in conjunction with other components to prevent the aerosol-generating substrate in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51, and to guide the aerosol-generating substrate in the second liquid storage chamber 51 into the first liquid storage chamber 111. In one embodiment, the locking member 70 can be disposed in the first liquid storage chamber 111. In another embodiment, the locking member 70 can be disposed in the second liquid storage chamber 51. In yet another embodiment, the locking member 70 can be disposed in both the first liquid storage chamber 111 and the second liquid storage chamber 51.

[0038] When the locking member 70 is provided on the atomizer 100, the aerosol-generating substrate in the first liquid storage chamber 111 will not flow into the second liquid storage chamber 51, regardless of whether the atomizer 100 is placed horizontally or vertically. Furthermore, the aerosol-generating substrate in the second liquid storage chamber 51 can promptly replenish the first liquid storage chamber 111. The aerosol-generating substrate is always present in the first liquid storage chamber 111, preventing the heating element 90 from drying out or burning, and providing a better puffing experience for the user.

[0039] In current atomizers, due to the high viscosity of the aerosol-generating substrate, continuity between the aerosol-generating substrate in the first and second liquid reservoirs is lost when the atomizer is stored horizontally for extended periods. When the atomizer is stored vertically, air entrapment in the first liquid reservoir is a common problem. This means that air in the first liquid reservoir is difficult to expel, while the aerosol-generating substrate in the second liquid reservoir is difficult to flow into the first liquid reservoir. This can easily lead to dry heating and burning of the heating element.

[0040] The locking member 70 of the present application allows the aerosol-generating substrate in the second liquid storage chamber 51 to replenish the first liquid storage chamber 111 regardless of whether the atomizer 100 is placed horizontally or vertically. That is, the aerosol-generating substrate in the second liquid storage chamber 51 and the aerosol-generating substrate in the first liquid storage chamber 111 remain continuous. Therefore, when the atomizer 100 is placed horizontally and then vertically, air is not trapped in the first liquid storage chamber 111, and the heating element 90 does not dry out or burn.

[0041] In the atomizer 100 of the embodiment of the present application, a locking member 70 is provided in the first liquid storage chamber 111 and / or the second liquid storage chamber 51. The locking member 70 can prevent the aerosol generating matrix in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51, and is used to guide the aerosol generating matrix in the second liquid storage chamber 51 into the first liquid storage chamber 111. When the atomizer 100 is placed horizontally, the aerosol generating matrix in the first liquid storage chamber 111 will not flow into the second liquid storage chamber 51, and the aerosol generating matrix in the second liquid storage chamber 51 can replenish the first liquid storage chamber 111. The aerosol generating matrix can be kept in the first liquid storage chamber 111 at all times, so that the heating element 90 in the atomizer 100 will not suffer from dry burning or burning problems, and the user's inhalation taste is better.

[0042] The atomizer 100 will be further described below with reference to the accompanying drawings.

[0043] Please refer to Figures 2, 4 and 6. In some embodiments, the locking member 70 is sleeved on the second sub-portion 33. A first capillary groove 71 is formed between the locking member 70 and the liquid storage member 50. The first capillary groove 71 is used to prevent the aerosol-generating matrix in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51, and to guide the aerosol-generating matrix in the second liquid storage chamber 51 into the first liquid storage chamber 111.

[0044] Specifically, a first capillary groove 71 is formed between the outer peripheral wall of the locking member 70 and the inner wall of the liquid storage member 50. Preferably, the cross-sectional shape of the locking member 70 is the same as that of the liquid storage member 50, so that the opening size of each position of the first capillary groove 71 is the same. As shown in FIG6 , because the opening size of the first capillary groove 71 is relatively small, for example, the opening size of the first capillary groove 71 can be, but is not limited to, 0.2 mm, 0.3 mm, or 0.4 mm. When the surrounding liquid level drops, because the surface tension of the aerosol-generating substrate is greater than the cohesive force, the surrounding liquid level will drop but remain continuous, and the surrounding liquid will be replenished to the lower liquid level position. As a result, the aerosol-generating substrate in the first liquid storage chamber 111 will not flow into the second liquid storage chamber 51, while the aerosol-generating substrate in the second liquid storage chamber 51 will flow into the first liquid storage chamber 111 through the first capillary groove 71. When the atomizer 100 is placed horizontally, the first liquid storage chamber 111 can always maintain an aerosol-generating matrix, and the heating element 90 will not dry out or burn.

[0045] Referring to Figures 2 to 5 , in certain embodiments, the atomizer base 10 is provided with an air inlet 13 communicating with the outside world. The first sub-portion 31 is provided with a communication groove 311, which communicates with the air inlet 13. A second capillary groove 313 is formed between the communication groove 311 and the liquid storage member 50. The second capillary groove 313 is used to prevent the aerosol-generating substrate in the second liquid storage chamber 51 from flowing toward the air inlet 13.

[0046] Among them, the air inlet 13 is used to allow external air to enter the atomizer 100. The shape of the air inlet 13 can be, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral, or other polygons. The connecting groove 311 is used to connect with both the air inlet 13 and the second liquid storage chamber 51. When the user inhales, external air enters through the air inlet 13 and flows into the connecting groove 311 from the gap between the first sub-section 31 of the air guide 30 and the atomizer seat 10, and finally flows into the second liquid storage chamber 51 from the connecting groove 311. When the aerosol-generating substrate in the second liquid storage chamber 51 flows into the first liquid storage chamber 111, the external air can enter the second liquid storage chamber 51 through the air inlet 13 and the connecting groove 311, thereby balancing the air pressure in the second liquid storage chamber 51 so that the aerosol-generating substrate in the second liquid storage chamber 51 can flow smoothly into the first liquid storage chamber 111. The number of connecting grooves 311 can be, but is not limited to, one, two, three, or more. When there are multiple connecting grooves 311, ambient air can quickly enter the second liquid storage chamber 51, allowing the aerosol-generating substrate in the second liquid storage chamber 51 to quickly flow into the first liquid storage chamber 111. In the present application, there are two connecting grooves 311, and thus two second capillary grooves 313 are formed between the connecting grooves 311 and the inner wall of the liquid storage member 50. The second capillary grooves 313 communicate with both the air inlet 13 and the second liquid storage chamber 51.

[0047] When the aerosol-generating matrix in the second liquid storage chamber 51 flows toward the first liquid storage chamber 111, part of the aerosol-generating matrix will flow into the second capillary groove 313. Since the opening size of the second capillary groove 313 is small and the surface tension of the aerosol-generating matrix is ​​large, the aerosol-generating matrix will not flow from the second capillary groove 313 to the air inlet 13, and the air inlet 13 will not be clogged. When the atomizer 100 is placed horizontally, when the heating element 90 heats the aerosol-generating matrix, the heat of the heating element 90 can be conducted to the second capillary groove 313. After being heated, the fluidity of the aerosol-generating matrix in the second capillary groove 313 increases, so the aerosol-generating matrix in the second capillary groove 313 will flow back into the second liquid storage chamber 51 and flow from the second liquid storage chamber 51 into the first liquid storage chamber 111, resulting in a high utilization rate of the aerosol-generating matrix.

[0048] Referring to Figures 3 and 4 , in some embodiments, the opening size of the second capillary groove 313 is larger than the opening size of the first capillary groove 71. For example, if the opening size of the first capillary groove 71 is 3 mm, the opening size of the second capillary groove 313 may be, but is not limited to, 4 mm, 5 mm, or 6 mm. If the opening size of the second capillary groove 313 is smaller than or equal to the opening size of the first capillary groove 71, after the aerosol-generating substrate in the second liquid storage chamber 51 enters the second capillary groove 313, the second capillary groove 313 is unable to connect with the air inlet 13 and the second liquid storage chamber 51. As a result, ambient air entering the atomizer 100 through the air inlet 13 cannot flow into the second liquid storage chamber 51 through the second capillary groove 313. Since the second liquid storage chamber 51 is a closed space, the aerosol-generating substrate in the second liquid storage chamber 51 cannot flow into the first liquid storage chamber 111, and the heating element 90 is prone to dry burning and scorching. When the opening size of the second capillary groove 313 is larger than the opening size of the first capillary groove 71, after the aerosol-generating substrate in the second liquid storage chamber 51 enters the second capillary groove 313, the second capillary groove 313 can connect the air inlet 13 and the second liquid storage chamber 51. The external air entering the atomizer 100 through the air inlet 13 can flow into the second liquid storage chamber 51 through the second capillary groove 313. The external air can enter the second liquid storage chamber 51 to balance the air pressure in the second liquid storage chamber 51, so that the aerosol-generating substrate in the second liquid storage chamber 51 can smoothly flow out of the first liquid storage chamber 111.

[0049] Please refer to Figures 3 and 4. In some embodiments, a receiving chamber 11 is formed between the atomizer seat 10 and the first sub-section 31. The heating element 90 is disposed in the receiving chamber 11, and the receiving chamber 11 is divided into a first liquid storage chamber 111 and an atomization chamber 113. Among them, a receiving chamber 11 is formed between the atomizer seat 10 and the inner wall surface of the first sub-section 31. The receiving chamber 11 is used for loading the heating element 90 and the aerosol generating matrix therein. The heating element 90 heats the aerosol generating matrix in the receiving chamber 11 to generate an aerosol. The aerosol generating matrix in the second liquid storage chamber 51 flows into the first liquid storage chamber 111. The aerosol generating matrix in the first liquid storage chamber 111 enters the micropores of the heating element 90 and is heated by the heating element 90 to form an aerosol. The aerosol enters the atomization chamber 113 and flows from the atomization chamber 113 into the air guide 30, thereby being inhaled by the user.

[0050] Please refer to Figures 7 and 8. In other embodiments, at least a portion of the locking member 70 is located in the first liquid storage chamber 111 and is connected to the heating element 90. The locking member 70 is used to conduct the aerosol generating matrix in the second liquid storage chamber 51 to the heating element 90, and to prevent the aerosol generating matrix in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51.

[0051] Specifically, the locking member 70 of the present application can be an oil-guiding cotton. When the atomizer 100 is placed horizontally or vertically, the oil-guiding cotton can guide the aerosol-generating matrix in the second liquid storage chamber 51 to the first liquid storage chamber 111. Preferably, at least a portion of the oil-guiding cotton is connected to the heating element 90, so that the oil-guiding cotton can directly guide the aerosol-generating matrix from the second liquid storage chamber 51 to the surface of the heating element 90, and the heating element 90 heats the aerosol-generating matrix more efficiently. The oil-guiding cotton can fill the entire first liquid storage chamber 111, so that when the oil-guiding cotton guides the aerosol-generating matrix in the second liquid storage chamber 51 to the surface of the heating element 90, the aerosol-generating matrix in the first liquid storage chamber 111 will not flow into the second liquid storage chamber 51. The first liquid storage chamber 111 can always be kept filled with the aerosol-generating matrix, the heating element 90 will not suffer from dry burning or burning problems, and the user's puffing experience is better.

[0052] The heating element 90 has opposite sides located in the first liquid storage chamber 111 and the atomization chamber 113, respectively. When the oil-conducting cotton contacts one side of the heating element 90, it can contact a portion of that side of the heating element 90, or it can contact the entire surface of that side of the heating element 90. Preferably, the oil-conducting cotton contacts the entire surface of that side of the heating element 90, so that the entire surface of the heating element 90 can contact the aerosol-generating substrate, and the heating element 90 heats the aerosol-generating substrate more efficiently.

[0053] In other embodiments, the atomizer 100 may include both a locking member 70 sleeved on the second sub-portion 33 of the air guide 30 and oil-conducting cotton installed in the first liquid storage chamber 111. In this case, when the atomizer 100 is placed horizontally, the aerosol-generating substrate in the first liquid storage chamber 111 will not flow into the second liquid storage chamber 51, and the aerosol-generating substrate in the second liquid storage chamber 51 can replenish the first liquid storage chamber 111 in a timely manner, thereby preventing the heating element 90 from drying out or burning.

[0054] Referring to Figures 7 and 8 , further, in certain embodiments, the end of the locking member 70 proximal to the second sub-portion 33 of the air guide 30 extends into the second liquid storage chamber 51 and surrounds the second sub-portion 33. In this case, when the atomizer 100 is placed horizontally at any angle, the locking member 70 can contact the aerosol-generating substrate in the second liquid storage chamber 51. Thus, the locking member 70 can guide the aerosol-generating substrate in the second liquid storage chamber 51 to the surface of the heating element 90, preventing the heating element 90 from drying out or burning.

[0055] 3 and 7 , in some embodiments, the air guide 30 has a channel 35 , and the atomizing chamber 113 is connected to both the air inlet 13 and the channel 35 . The atomizer 100 further includes a nozzle 40 having a through hole 41 connected to the channel 35 .

[0056] The channel 35 and the through-hole 41 are both used to allow aerosol and ambient air to circulate therethrough. The nozzle 40 facilitates the user's inhalation of the aerosol generating device 1000. After the aerosol-generating matrix in the first liquid storage chamber 111 is heated by the heating element 90, the generated aerosol enters the atomizing chamber 113 through the micropores of the heating element 90. During the user's inhalation, ambient air enters through the air inlet 13, enters the atomizing chamber 113, and carries the aerosol with it into the channel 35, ultimately flowing out through the through-hole 41 to be inhaled by the user.

[0057] The mouthpiece 40 is connected to the air guide 30, thereby enabling communication between the passage 35 and the through-hole 41. Preferably, a first seal 43 is disposed between the mouthpiece 40 and the air guide 30. The first seal 43 is used to seal the gap between the mouthpiece 40 and the air guide 30, preventing aerosol from flowing out of the gap between the mouthpiece 40 and the air guide 30 into the second liquid storage chamber 51 or even out of the atomizer 100. The first seal 43 can be made of materials such as rubber, silicone, plastic, or synthetic fiber.

[0058] Please refer to Figures 4 and 8. Furthermore, in some embodiments, the atomizer 100 also includes a second sealing member 60, which is arranged around the heating element 90. The second sealing member 60 and the heating element 90 are used to separate the accommodating chamber 11 into a first liquid storage chamber 111 and an atomizing chamber 113 that are not connected to each other.

[0059] The second sealing member 60 is used to seal the gap between the heating element 90 and the second subsection 33 of the air guide 30, as well as the gap between the heating element 90 and the atomizer seat 10. The second sealing member 60 can be made of materials such as rubber, silicone, plastic, or synthetic fiber. Among them, rubber materials include but are not limited to natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. When the second sealing member 60 is made of rubber material, the contact between the second sealing member 60 and the heating element 90 and the second subsection 33 of the air guide 30 is tighter, thereby improving the sealing effect of the second sealing member 60 on the gap between the heating element 90 and the second subsection 33 of the air guide 30. The contact between the second sealing member 60 and the heating element 90 and the atomizer 100 is also tighter, thereby improving the sealing effect of the second sealing member 60 on the gap between the heating element 90 and the atomizer 100. The number of second sealing members 60 in this application is two. When the number of second sealing members 60 is two, the sealing effect of the second sealing member 60 is better. The second sealing member 60 can prevent the aerosol-generating substrate in the first liquid storage chamber 111 from entering the atomizer 100 and leaking out of the air inlet 13 or even blocking the air inlet 13 .

[0060] The second sealing member 60 is used to prevent the aerosol generating matrix in the first liquid storage chamber 111 from flowing directly into the atomizing chamber 113. If the unheated aerosol generating matrix flows directly into the atomizing chamber 113, it will cause a waste of the aerosol generating matrix. In addition, if the aerosol generating matrix in the first liquid storage chamber 111 flows into the atomizing chamber 113, the aerosol generating matrix will flow toward the air inlet 13, thereby blocking the air inlet 13. When the air inlet 13 is blocked, when the user inhales, the outside gas cannot enter the atomizing chamber 113. The outside gas cannot carry the aerosol out of the channel 35 and the through hole 41, and the outside gas cannot enter the second liquid storage chamber 51 to balance the air pressure in the second liquid storage chamber 51.

[0061] 2 and 9 , the aerosol generating device 1000 according to the embodiment of the present application includes a battery assembly 300 and the atomizer 100 according to the above embodiment. The atomizer 100 further includes an electrical connector 80 , which electrically connects the heating element 90 and the battery assembly 300 .

[0062] The battery assembly 300 is used to power the heating element 90 in the atomizer 100, so that the heating element 90 can generate heat to heat the aerosol-generating matrix. The atomizer seat 10 of the present application is provided with threads, and the battery assembly 300 and the atomizer 100 are detachably connected via the threads.

[0063] The electrical connector 80 is used to electrically connect the battery assembly 300 and the heating element 90 so that the heating element 90 and the battery assembly 300 are electrically connected. When the user inhales, the battery assembly 300 provides electrical energy to the heating element 90, so that the heating element 90 generates heat, and the aerosol generating matrix absorbs the heat to generate an aerosol. The electrical connector 80 can be, but is not limited to, an elastic thimble or a wire. Preferably, a bracket 81 is provided on the atomizer seat 10, and the bracket 81 is used to install and fix the electrical connector 80. The electrical connector 80 is firmly mounted on the atomizer seat 10, so that the electrical connector 80 can stably connect the heating element 90 and the battery assembly 300.

[0064] In the aerosol generating device 1000 of the embodiment of the present application, a locking member 70 is provided in the first liquid storage chamber 111 and / or the second liquid storage chamber 51. The locking member 70 can prevent the aerosol generating substrate in the first liquid storage chamber 111 from flowing into the second liquid storage chamber 51, and is used to guide the aerosol generating substrate in the second liquid storage chamber 51 into the first liquid storage chamber 111. When the atomizer 100 is placed horizontally, the aerosol generating substrate in the first liquid storage chamber 111 will not flow into the second liquid storage chamber 51, and the aerosol generating substrate in the second liquid storage chamber 51 can replenish the first liquid storage chamber 111. The aerosol generating substrate can be kept in the first liquid storage chamber 111 at all times, so that the heating element 90 in the atomizer 100 will not dry out or burn, and the user's inhalation taste is better.
