[0039] Reference to "embodiment" in this context means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] The following provides a detailed description of this application in conjunction with the drawings and embodiments.

[0041] Please refer to Figures 1 to 6 ; wherein, Figure 1 is an exploded view of an aerosol generating device provided by an embodiment of this application; Figure 2 is Figure 1 a sectional view taken along the line A-A of the aerosol generating device shown; Figure 3 is Figure 1 a sectional view taken along the line B-B of the aerosol generating device shown; Figure 4 is a schematic structural view of an atomizing base under a first visual angle provided by an embodiment of this application; Figure 5 is a schematic structural view of an atomizing base under a second visual angle provided by an embodiment of this application; Figure 6Schematic diagram of the atomizing base under the third vision provided by an embodiment of the present application. In this embodiment, an aerosol generating device is provided. The aerosol generating device can be used in technical fields such as medical treatment, beauty, electronic cigarettes, and household appliances, and is used to heat and atomize an aerosol generating matrix to form an aerosol when powered on. Among them, the aerosol generating matrix can be a liquid medicine formed by dispersing a certain drug in a liquid solvent, e-cigarette oil, or any other liquid suitable for electronic atomization. Among them, the aerosol generating device specifically includes a housing 1, an atomizing bracket 2, an atomizing core 3, an atomizing base 4, an airflow sensor 5, and a battery 6.

[0042] As Figures 1 to 3 shown, the housing 1 includes a first housing 11 and a second housing 12. The first housing 11 has a first air inlet 111 and a receiving cavity with an open end; the end of the receiving cavity away from the opening defines a battery receiving cavity, and the battery 6 is located in the battery receiving cavity. The atomizing base 4 is received in the first housing 11 through the opening of the first housing 11 and is located on the side of the battery receiving cavity facing the second housing 12; and the end wall of the atomizing base 4 facing the battery receiving cavity, that is, the end wall facing the battery 6, is sealingly connected to the inner wall surface of the first housing 11 and serves as the cavity wall of the battery receiving cavity. Hereinafter, this cavity wall is defined as a partition 41. The partition 41 can isolate the battery 6 disposed in the battery receiving cavity from the liquid storage cavity 121 formed by the second housing 12, so as to prevent the aerosol generating matrix or aerosol condensate in the liquid storage cavity 121 from leaking into the battery receiving cavity and damaging the battery 6.

[0043] Specifically, the first housing 11 can be an integrally formed structure; of course, the first housing 11 can also be a hollow structure formed by buckling front and back or left and right. The first housing 11 can also be made of a light-transmitting material to facilitate observing the situation inside the first housing 11. The light-transmitting material can be heat-resistant glass or plastic, etc. Of course, the first housing 11 can also be made of a non-light-transmitting material, which is not specifically limited herein.

[0044] The second housing 12 also forms a hollow cavity, a mouthpiece 120, and a first air outlet channel 122 communicating with the mouthpiece 120 (see Figure 2); and the second shell 12 is fixedly connected to the first shell 11 to achieve the non-detachable aerosol generating device, which can prevent the aerosol generating matrix leaking out when the aerosol generating device is disassembled from contaminating the user; and when the user is inhaling, it can reduce the proportion of the airflow coming from the gap between the first shell 11 and the second shell 12 in the formed airflow, thereby effectively improving the sensitivity of the airflow sensor 5. Specifically, a snap-fit groove can be provided on the first shell 11, and a snap-fit buckle can be provided on the outer side wall of the second shell 12. The first shell 11 and the second shell 12 can be snapped into the snap-fit groove by the snap-fit buckle to achieve a fixed connection between the two. Of course, the snap-fit buckle can be provided on the first shell 11, and the snap-fit groove can be provided on the second shell 12; or the first shell 11 and the second shell 12 can be fixed by other means such as welding.

[0045] The atomizing bracket 2 is located between the liquid storage chamber 121 and the battery receiving chamber, and cooperates with the atomizing base 4 to form an atomizing chamber. Figure 1 The atomizing bracket 2 is formed with a liquid inlet 21 communicating with the liquid storage chamber 121, a second air outlet channel 22 communicating with the first air outlet channel 122, an aerosol flow groove 23 communicating with the second air outlet channel 22 and the atomizing chamber, and a fixing groove 25 (see FIG. Figure 3 The fixing groove 25 is located on the end surface of the atomizer bracket 2 facing the battery receiving chamber. The atomizer core 3 is accommodated in the fixing groove 25 and covers the liquid inlet hole 21, so that the aerosol-generating matrix flowing out of the liquid storage chamber 121 through the liquid inlet hole 21 directly reaches the surface of the atomizer core 3. Then, when the atomizer core 3 is powered, the aerosol-generating matrix is atomized to form an aerosol. The formed aerosol flows out through the aerosol flow groove 23, the second air outlet channel 22, and the first air outlet channel 122 in sequence.

[0046] In the specific embodiment, please refer to Figure 2 The atomizing base 4 is located between the liquid storage chamber 121 and the battery receiving chamber along its axial direction D. Figure 1 and Figure 4 The atomizing base 4 specifically includes an atomizing tank 42, a leakage collecting chamber 43, a sealing cover 433, a sensor accommodating chamber 44 and a first vent hole 422. Figures 1 to 3 As shown, the atomizer tank 42 is located on the side of the atomizer base 4 facing the liquid storage chamber 121, and the atomizer bracket 2 is specifically covered at one end of the atomizer tank 42 away from the battery receiving chamber and extends into the atomizer tank 42. The bottom of the atomizer bracket 2 cooperates with the bottom of the atomizer tank 42 to form an atomizer chamber. In a specific embodiment, as shown in FIG. Figure 6 As shown, the bottom wall of the atomizing tank 42 is further formed with a liquid locking tank 421 for storing the aerosol generating substrate or aerosol condensate in the atomizing chamber. Figure 4As shown, the first ventilation hole 422 is formed in the bottom wall of the atomization tank 42 and is located between the atomization tank 42 and the liquid leakage collection cavity 43; the first ventilation hole 422 is respectively communicated with the atomization tank 42 and the liquid leakage collection cavity 43; and when the aerosol generating device is placed vertically, that is, along the axial direction D of the atomization base 4, the height of the position where the opening of the first ventilation hole 422 communicated with the atomization tank 42 is higher than the height of the notch of the liquid locking groove 421, so as to prevent the aerosol generating matrix or aerosol condensate in the liquid locking groove 421 from leaking through the first ventilation hole 422.

[0047] As Figures 4 to 6 shown, the liquid leakage collection cavity 43 and the sensor accommodation cavity 44 are both located between the partition plate 41 and the atomization tank 42. Among them, the liquid leakage collection cavity 43 is used to collect the aerosol generating matrix and aerosol condensate leaked from the atomization tank 42 through the first ventilation hole 422, so as to prevent the leaked aerosol generating matrix and aerosol condensate from entering the battery accommodation cavity and damaging the battery 6.

[0048] Specifically, as Figure 3 and Figure 4 shown, the opening of the liquid leakage collection cavity 43 faces the inner side wall of the first housing 11, and the sealing cover 433 is covered on the opening of the liquid leakage collection cavity 43 and elastically abuts against the opening of the liquid leakage collection cavity 43 to seal the liquid leakage collection cavity 43; in this way, after atomization, it can prevent the remaining aerosol diffused into the liquid leakage collection cavity 43 from diffusing to other places for condensation, thereby better preventing the leakage of aerosol condensate. The sealing cover 433 is provided with a second intake hole 4331, the first end of the second intake hole 4331 is communicated with the first intake hole 111, and the second intake hole 4331 extends along the radial direction of the atomization base 4; the second end of the second intake hole 4331 is communicated with the liquid leakage collection cavity 43; in a specific embodiment, when the user inhales the aerosol, the external air flow sequentially enters the liquid leakage collection cavity 43 through the first intake hole 111 and the second intake hole 4331, and then enters the atomization cavity through the first ventilation hole 422.

[0049] Furthermore, as Figure 2 shown, in order to better seal the liquid leakage collection cavity 43, the aerosol generating device may further include a first sealing ring 7a and a second sealing ring 7b. The first sealing ring 7a and the second sealing ring 7b are both sleeved on the outer peripheral surface of the atomization base 4, and the liquid leakage collection cavity 43 is located between the first sealing ring 7a and the second sealing ring 7b, so as to further seal the liquid leakage collection cavity 43 through the first sealing ring 7a and the second sealing ring 7b. Specifically, as Figure 5 shown, a sealing groove 429a and a sealing groove 429b are formed on the outer side wall of the atomization base 4, and the first sealing ring 7a is snap-fitted into the sealing groove 429a for fixation; the second sealing ring 7b is snap-fitted into the sealing groove 429b for fixation.

[0050] Among them, in order to further improve the liquid locking effect of the liquid leakage collection cavity 43 and prevent the aerosol generation matrix or aerosol condensate from leaking out of the liquid leakage collection cavity 43. In a specific embodiment, refer to Figure 7 , Figure 7 which is a schematic structural diagram of an atomizing base provided in another embodiment of the present application; a plurality of capillary grooves 431 can be further provided on the cavity wall of the liquid leakage collection cavity 43 to lock the liquid through the capillary action of the capillary grooves 431. Among them, the cavity wall of the liquid leakage collection cavity 43 may include a bottom wall and / or a side wall. In another specific embodiment, refer to Figure 8 , Figure 8 which is a schematic structural diagram of an atomizing base provided in yet another embodiment of the present application; an adsorbing member 432 can be further provided in the liquid leakage collection cavity 43 to absorb the aerosol generation matrix or aerosol condensate entering the liquid leakage collection cavity 43 through the adsorbing member 432. Among them, the adsorbing member 432 can be a component such as cotton cloth or sponge that can absorb liquid.

[0051] Reference can be made to Figures 1 to 3 . The sensor accommodation cavity 44 is used to place the airflow sensor 5; compared with the existing solution, the airflow sensor 5 is installed on the atomizing base 4 instead of on the bracket for installing the battery 6. Therefore, the airflow sensor 5 is closer to the atomizing cavity, which can effectively improve the sensing sensitivity of the airflow sensor 5, and the overall structure is more compact, which is beneficial to the miniaturization of the aerosol generating device and convenient for users to carry. In a specific embodiment, the orifice of the sensor accommodation cavity 44 faces the inner side wall of the first housing 11, and the airflow sensor 5 is detachably arranged in the sensor accommodation cavity 44; this is convenient for recycling the airflow sensor 5 and is more environmentally friendly. Specifically, the radial direction of the airflow sensor 5 is inclined at a certain angle with respect to the radial direction of the atomizing base 4, that is, the radial direction of the airflow sensor 5 is not parallel to the radial direction of the atomizing base 4; this can prevent the airflow sensor 5 from being soaked by the aerosol generation matrix or aerosol condensate, thereby further protecting the airflow sensor 5. Among them, the inclination angle can be greater than 0° and less than or equal to 90°. As Figure 3 shown, in a specific embodiment, the radial direction of the airflow sensor 5 is perpendicular to the radial direction of the atomizing base 4.

[0052] In a specific embodiment, the linear distance between the liquid leakage collection chamber 43 and the atomization core 3 is not less than the linear distance between the sensor accommodation chamber 44 and the atomization core 3. In this way, when there is aerosol condensate or aerosol generation matrix in the sensor accommodation chamber 44, the aerosol condensate or aerosol generation matrix can flow towards the liquid leakage collection chamber 43 under its own gravity, reducing the accumulation of the aerosol condensate or aerosol generation matrix in the sensor accommodation chamber 44, thereby playing a role in protecting the airflow sensor 5 disposed in the sensor accommodation chamber 44. Among them, the linear distances between the liquid leakage collection chamber 43 and the sensor accommodation chamber 44 and the atomization core 3 both refer to the axial direction D of the atomization base 4, that is, the vertical distance between the side wall of the corresponding cavity away from the atomization core 3 and the plane where the atomization core 3 is located.

[0053] In a specific embodiment, the liquid leakage collection chamber 43 and the sensor accommodation chamber 44 are arranged at intervals along the circumferential direction of the atomization base 4, and their linear distances from the atomization core 3 are the same, that is, the liquid leakage collection chamber 43 and the sensor accommodation chamber 44 are arranged side by side along the radial direction of the atomization base 4. In this way, it is not only convenient for processing, but also the product structure is compact, and the product volume can be reduced. Specifically, referring to Figure 4 and Figure 5 , the bottom wall of the atomization groove 42 is arranged at intervals with the partition plate 41 and is connected by a baffle 45. The baffle 45 divides the space between the bottom wall of the atomization groove 42 and the partition plate 41 into two parts. The first part serves as the liquid leakage collection chamber 43, and the second part is used to arrange the sensor accommodation chamber 44, and the baffle 45 also serves as the side wall of the liquid leakage collection chamber 43 and the bottom wall of the sensor accommodation chamber 44. It can be understood that in this embodiment, the linear distances between the liquid leakage collection chamber 43 and the sensor accommodation chamber 44 and the atomization core 3 both refer to the vertical distance between the partition plate 41 and the plane where the atomization core 3 is located.

[0054] In a specific embodiment, as Figure 4 shown, a second ventilation hole 451 is also opened on the baffle 45. The second ventilation hole 451 is communicated with the liquid leakage collection chamber 43 and the sensor accommodation chamber 44, and serves as a pressure trigger channel for the airflow sensor 5 installed in the sensor accommodation chamber 44 to work. Among them, the sensor accommodation chamber 44 is communicated with the first ventilation hole 422 through the second ventilation hole 451 and the liquid leakage collection chamber 43, and then communicated with the atomization groove 42. Compared with the scheme that the first ventilation hole 422 directly communicates the atomization groove 42 and the sensor accommodation chamber 44, it can not only trigger the airflow sensor 5 to work when the user sucks, but also prevent the aerosol generation matrix or aerosol condensate leaking through the first ventilation hole 422 from directly entering the sensor accommodation chamber 44, resulting in the problem of damage to the airflow sensor 5. Preferably, the first ventilation hole 422 extends along the axial direction D of the atomization base 4, and the second ventilation hole 451 extends along the radial direction of the atomization base 4, thus preventing the aerosol generation matrix or aerosol condensate from leaking directly into the sensor accommodation chamber 44.

[0055] Specifically, when the aerosol generating device is placed vertically, that is, along the axial direction D of the atomizing base 4, the vertical distance between the second ventilation hole 451 and the plane where the atomizing core 3 is located is less than the vertical distance between the bottom wall of the liquid leakage collection cavity 43 (i.e., the partition 41) and the plane where the atomizing core 3 is located. In this way, when using the aerosol generating device, it can effectively avoid the problem that the aerosol generating matrix or aerosol condensate collected in the liquid leakage collection cavity 43 overflows into the sensor accommodation cavity 44 through the second ventilation hole 451, preventing the airflow sensor 5 from being damaged. Further, the second ventilation hole 451 can be arranged close to the first ventilation hole 422. In this way, when there is airflow passing through the first ventilation hole 422, the airflow sensor 5 can be quickly triggered to work, thereby effectively improving the sensitivity of the airflow sensor 5.

[0056] In one embodiment, referring to Figure 4 and Figure 9 , Figure 9 is a schematic diagram of the second ventilation hole and the connection hole provided in an embodiment of the present application; the second ventilation hole 451 specifically includes a first ventilation section 451a and a second ventilation section 451b that are communicated with each other. The first ventilation section 451a is communicated with the liquid leakage collection cavity 43, and the second ventilation section 451b is communicated with the sensor accommodation cavity 44; and the angle α formed by the first ventilation section 451a and the second ventilation section 451b is greater than 0° and less than 180°. Among them, by making the second ventilation hole 451 include the first ventilation section 451a and the second ventilation section 451b arranged at a certain angle, the ventilation path of the second ventilation hole 451 can be extended, so that when the aerosol generating device works, the aerosol diffused into the second ventilation hole 451 forms condensate in the second ventilation hole 451 as much as possible, thereby effectively reducing the damage rate of the remaining aerosol diffusing into the sensor accommodation cavity 44 and causing damage to the airflow sensor 5. In a specific embodiment, the second ventilation section 451b is perpendicular to the first ventilation section 451a; and as Figure 5 and Figure 9 shown, a connection hole 452 is further formed by extending the end of the second ventilation section 451b facing away from the sensor accommodation cavity 44.

[0057] Referring to Figure 1 , Figure 3 and Figures 10a to 10b , wherein, Figure 10a is a schematic diagram of the structure of the sensor bracket under the first visual angle provided in an embodiment of the present application; Figure 10b is a schematic diagram of the structure of the sensor bracket under the second visual angle provided in an embodiment of the present application; Figure 11Schematic diagram of a part of the sleeve body portion located in the sensor accommodation cavity. The aerosol generating device further includes a sensor bracket 8, a part of the sensor bracket 8 is disposed in the sensor accommodation cavity 44, and the airflow sensor 5 is specifically detachably disposed on the sensor bracket 8, so as to be detachably disposed in the sensor accommodation cavity 44 through the sensor bracket 8.

[0058] As Figure 10a shown, the sensor bracket 8 includes a sleeve body portion 81 and a first connecting ear 82. Among them, as Figure 3 shown, at least a part of the sleeve body portion 81 is located in the sensor accommodation cavity 44, and as Figures 10a to 11 shown, the first end of the sleeve body portion 81 is an open end, and the airflow sensor 5 is installed in the sleeve body portion 81 through the open end; and there is a blocking wall 812 at the second end of the sleeve body portion 81, and a third ventilation hole 813 is provided at the blocking wall 812, and the third ventilation hole 813 is communicated with the second ventilation section 451b of the second ventilation hole 451, so as to communicate the airflow sensor 5 located in the sleeve body portion 81 with the second ventilation hole 451 through the third ventilation hole 813; at the same time, the airflow sensor 5 can be limited by the blocking wall 812.

[0059] In a specific embodiment, as Figure 11 shown, at least two spaced-apart top posts 814 are formed by the blocking wall 812 extending towards the cavity wall of the sensor accommodation cavity 44, and the sensor accommodation cavity 44 is abutted against the bottom wall through at least two top posts 814. Among them, by the top posts 814 abutting against the bottom wall of the sensor accommodation cavity 44, the blocking wall 812 can be spaced apart from the sensor accommodation cavity 44, which can not only ensure that the air passage is not easily blocked, but also avoid the problem that the aerosol generating matrix or aerosol condensate entering the sensor accommodation cavity 44 through the second ventilation hole 451 directly contacts the airflow sensor 5 and damages the airflow sensor 5; as Figure 11 shown, at the same time, a pressure cavity 815 can be formed by the cooperation of the blocking wall 812 with the cavity wall and the side wall of the sensor accommodation cavity 44. The pressure cavity 815 can not only store part of the aerosol generating matrix or aerosol condensate entering the sensor accommodation cavity 44, but also, due to the small volume of the pressure cavity 815, generally 20 cm 3 -200 cm 3 , therefore, as long as the air pressure in the pressure cavity 815 changes slightly, it can be sensed, thereby effectively avoiding the problem that the airflow sensor 5 mistakenly thinks it is damaged because it does not receive a trigger signal, and effectively improving the sensitivity of the airflow sensor 5.

[0060] As Figure 10a and Figure 10bAs shown, the first end of the first connecting ear 82 is connected to the sleeve portion 81. A fixing post 821 is provided on the second end of the first connecting ear 82 facing one side surface of the atomizing base 4. The fixing post 821 is inserted and connected to the connecting hole 452 to fix the first connecting ear 82 to the atomizing base 4. Through the insertion and fixation of the fixing post 821 and the connection, not only is the connection firm, but also the manufacturing process is simplified.

[0061] In one embodiment, please also refer to Figure 5 and Figure 10a , the atomizing base 4 further forms a connecting groove 441. The connecting groove 441 is located on the first side of the inductor accommodating cavity 44, and the connecting hole 452 is located on the second side of the inductor accommodating cavity 44. The first side and the second side of the inductor accommodating cavity 44 are respectively located on two opposite sides of the inductor accommodating cavity 44 in terms of position; the inductor bracket 8 further includes a second connecting ear 83. The first end of the second connecting ear 83 is connected to the sleeve portion 81, and the second end of the second connecting ear 83 is inserted and connected to the connecting groove 441. In a specific embodiment, a clamping plate 441a is provided on the groove wall of the connecting groove 441, and a clamping groove 831 is provided on the second connecting ear 83. The clamping plate 441a is inserted into the clamping groove 831 to fix the second connecting ear 83 to the atomizing base 4, thereby increasing the connection reliability between the inductor bracket 8 and the atomizing base 4. Specifically, the number of the clamping plates 441a is two, the two clamping plates 441a are arranged at intervals, and the groove wall of the clamping groove 831 elastically abuts against each clamping plate 441a to further enhance the connection reliability and avoid the problem that the groove wall of the clamping groove 831 is in rigid contact with the clamping plate 441a, resulting in damage to the second connecting ear 83 or the connecting groove 441.

[0062] In a specific embodiment, please refer to Figure 1 and Figure 2 , the aerosol generating device further includes an electrode 91, an electronic wire 92, a sealing cover 93, a sealing seat 94, and a third sealing ring 7c. Among them, the electrode 91 is fixed in the atomizing groove 42 of the atomizing base 4, abuts against the atomizing core 3, and is connected to the battery 6 through the electronic wire 92 to supply power to the atomizing core 3. Specifically, as Figure 2 shown, the electrode 91 includes a conductive column portion and a blocking ring portion; the first end of the conductive column portion is connected to the bottom wall of the atomizing groove 42, the second end of the conductive column portion abuts against the atomizing core 3; the blocking ring portion is disposed around the outer peripheral surface of the conductive column portion and is connected to the conductive column portion; and it is located on the bottom wall surface of the atomizing groove 42 for limiting the electrode 91 to prevent poor contact between the electrode 91 and the atomizing core 3.

[0063] As Figure 1 , Figure 2 and Figure 12 , Figure 12Schematic diagram of the sealing cover covering the end face of the atomization bracket facing the liquid storage cavity; the sealing cover 93 covers the side of the atomization bracket 2 facing the liquid storage cavity 121 and wraps one end of the atomization base 4 facing the liquid storage cavity 121, thereby improving the sealing performance of the atomization cavity. Specifically, the sealing cover 93 is made of an elastic material. As Figure 12 shown, the sealing cover 93 includes an end wall 931 and an annular side wall 932; wherein, the side wall 932 is sleeved on the outer peripheral surfaces of the atomization bracket 2 and the atomization base 4; the end wall 931 is located at the end face of the side wall 932 and is connected to the side wall 932, and the end wall 931 covers the end face of the atomization bracket 2 facing the liquid storage cavity 121.

[0064] Specifically, the sealing cover 93 has a first opening 933 corresponding to the position of the liquid inlet hole 21 of the atomization bracket 2 to ensure that the aerosol-forming matrix in the liquid storage cavity 121 can smoothly enter the liquid inlet hole 21. The sealing cover 93 has a second opening 934 corresponding to the second air outlet channel 22 of the atomization bracket 2 to ensure that the first air outlet channel 122 can communicate with the second air outlet channel 22 through the second opening 934.

[0065] As Figures 1 to 3 and Figure 13 shown, Figure 13 Schematic diagram of the sealing seat abutting against the atomization bracket; the sealing seat 94 is arranged in the fixing groove 25 and wraps the circumferential side of the atomization core 3, located between the atomization core 3 and the liquid inlet hole 21, and is used to prevent the aerosol-forming matrix flowing out of the liquid inlet hole 21 from directly flowing out of the gap between the atomization core 3 and the atomization bracket 2 into the atomization cavity. Specifically, as Figure 1 shown, the sealing seat 94 is provided with a liquid guiding hole 941 corresponding to the position of the liquid inlet hole 21 to guide the aerosol-forming matrix flowing out of the liquid inlet hole 21 to the surface of the atomization core 3. In a specific embodiment, as Figure 1 shown and combined with Figure 13 , a plurality of elastic abutting columns 942 are arranged at intervals on the end face of the sealing seat 94 facing away from the battery accommodation cavity, and the elastic abutting columns 942 are elastically abutted against the groove wall of the fixing groove 25. By arranging the elastic abutting columns 942, when the atomization core 3 is installed in the atomization bracket 2, the elastic abutting columns 942 can relatively flatly abut against the groove wall of the fixing groove 25, so that the elastic deformation of the area of the sealing seat 94 where the elastic abutting columns 942 are located is more uniform, and the atomization core 3 in the sealing seat 94 is prevented from cracking due to uneven stress.

[0066] The third sealing ring 7c is embedded in the sealing groove 429c on the periphery of the atomization base 4 and is located between the liquid storage cavity 121 and the liquid leakage collection cavity 43 along the axial direction D of the atomization base 4, so as to prevent the aerosol generating matrix and / or aerosol condensate in the liquid storage cavity 121 from leaking from the gap between the atomization base 4 and the first housing 11 to the battery accommodation cavity or the sensor accommodation cavity 44. Among them, the first sealing ring 7a, the second sealing ring 7b, the third sealing ring 7c, the sealing cover 93 and the sealing seat 94 can all be made of materials such as silica gel or rubber.

[0067] Certainly, in a specific embodiment, the aerosol generating device further includes other existing structures such as fixing parts and sealing parts in the existing aerosol generating device. For details, reference can be made to the prior art, and the same or similar technical effects can be achieved, which will not be elaborated here.

[0068] The aerosol generating device provided in this embodiment is provided with a liquid leakage collection cavity 43 and is communicated with the atomization core 3 through the first ventilation hole 422, so that the liquid leakage collection cavity 43 can be used to store the leaked aerosol generating matrix and / or aerosol condensate, preventing the aerosol generating matrix and / or aerosol condensate from leaking to the battery 6 of the power supply assembly or the airflow sensor 5 and damaging the battery 6 or the airflow sensor 5. At the same time, by making the linear distance between the liquid leakage collection cavity 43 and the atomization core 3 not less than the linear distance between the sensor accommodation cavity 44 and the atomization core 3, when there is aerosol condensate or aerosol generating matrix in the sensor accommodation cavity 44, the aerosol condensate or aerosol generating matrix can flow towards the liquid leakage collection cavity 43 due to gravity, reducing the accumulation of aerosol condensate or aerosol generating matrix in the sensor accommodation cavity 44, thereby playing a role in protecting the airflow sensor 5 provided in the sensor accommodation cavity 44.

[0069] In addition, by detachably arranging the air flow sensor 5 in the sensor accommodation cavity 44, it is convenient to recycle the air flow sensor 5, which is more environmentally friendly. In addition, by hermetically connecting the end wall of the atomizing base 4 facing the battery accommodation cavity to the first housing 11 and using it as the cavity wall of the battery accommodation cavity, the battery 6 arranged in the battery accommodation cavity can be isolated from the liquid storage cavity 121 through this cavity wall, preventing the aerosol generation matrix or aerosol condensate in the liquid storage cavity 121 from leaking into the battery accommodation cavity and damaging the battery 6. Furthermore, by making the sensor bracket 8 abut against the bottom wall of the sensor accommodation cavity 44 through the top post 814, not only can it ensure that the air passage is not easily blocked, but also it can avoid the problem that the aerosol generation matrix or aerosol condensate directly contacts the air flow sensor 5 and damages the air flow sensor 5; at the same time, it can make the blocking wall 812 cooperate with the cavity wall and the side wall of the sensor accommodation cavity 44 to form a pressure cavity 815. This pressure cavity 815 can not only store part of the aerosol generation matrix or aerosol condensate entering the sensor accommodation cavity 44, but also effectively avoid the problem that the air flow sensor 5 mistakenly thinks it is damaged because it does not receive a trigger signal, effectively improving the sensitivity of the air flow sensor 5.
