DETAILED DESCRIPTION

[0040] It should be noted that the embodiments and technical features in the embodiments can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation and illustration of the purpose of the present application, and should not be regarded as an improper limitation on the present application.

[0041] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and these orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments. Figure 2

[0042] The present application provides an aerosol generating device, please refer to Figure 1 , Figure 2 and​Figure 4 , including an atomization seat assembly 10, an atomization core 20 having opposite atomization face 20a and liquid suction face 20b, an air outlet channel 54a, and a power supply assembly 30. The power supply assembly 30 is configured to supply power to the atomization core 20 and control the atomization core 20 to work so that the atomization core 20 can atomize the aerosol generating substrate to form an aerosol.

[0043] The aerosol generating device 100 is configured to atomize the aerosol generating substrate to generate an aerosol for a user to smoke.

[0044] The aerosol generating substrate includes, but is not limited to, a medicine, a nicotine-containing material, or a nicotine-free material, etc.

[0045] Referring to Figure 2 to Figure 8 The atomization seat assembly 10 forms an atomization space and a liquid storage cavity 10b for storing the aerosol generating substrate, and the liquid storage cavity 10b is in communication with the liquid suction face 20b. By forming the liquid storage cavity 10b and the atomization space in the atomization seat assembly 10 at the same time, the space of the atomization seat assembly 10 can be fully utilized, and the structural compactness can be improved.

[0046] Exemplarily, referring to Figure 2 to Figure 4 The atomization core 20 includes a substrate and a heating conductive film, and the atomization face 20a and the liquid suction face 20b are arranged on opposite sides of the substrate. The heating conductive film is arranged on the atomization face 20a and can generate heat after being powered.

[0047] The atomization core 20 is arranged in the atomization space, and the atomization face 20a and the atomization space facing the atomization face 20a define an atomization cavity 10a. The atomization core 20 is configured to atomize the aerosol generating substrate to generate an aerosol. The atomization face 20a is arranged towards the air outlet channel 54a, that is, the aerosol generating device 100 adopts bottom liquid supply. The aerosol generating substrate is guided to the atomization face 20a of the substrate through the liquid suction face 20b of the substrate. The substrate is configured to absorb the aerosol generating substrate. The heating conductive film on the atomization face 20a heats and atomizes the aerosol generating substrate to generate an aerosol.

[0048] The atomization core 20 blocks the flow of the aerosol generating substrate in the liquid storage cavity 10b, that is, the aerosol generating substrate does not directly flow into the liquid storage cavity 10b.

[0049] The atomization face 20a of the atomization core 20 is arranged towards the air outlet channel 54a. The aerosol generating substrate is heated and atomized at the atomization face 20a and releases the generated aerosol towards the atomization cavity 10a. The external air enters the atomization cavity 10a to mix with the aerosol and carries the aerosol out of the air outlet channel 54a for a user to use.

[0050] Exemplarily, referring to Figure 2The power supply assembly 30 comprises a battery 31 and a conductive piece 32. The battery 31 is electrically connected to the atomization core 20 through the conductive piece 32. The conductive piece 32 is arranged on the side of the atomization surface 20a facing the air outlet channel 54a and extends towards the air outlet channel 54a. Specifically, the conductive piece 32 abuts against the heating conductive film to achieve electrical connection between the conductive piece 32 and the heating conductive film. The battery 31 supplies power to the heating conductive film. The heating conductive film converts electrical energy into heat energy. The aerosol generating substrate can be converted into aerosol for user consumption under the action of the heat energy.

[0051] It should be noted that the specific manner in which the conductive piece 32 is arranged on the side of the atomization surface 20a facing the air outlet channel 54a and electrically connected to the battery 31 is not limited herein. For example, refer to Figure 2 to Figure 8 The power supply assembly 30 comprises a wire 33 (see Figure 2 in dashed lines). One end of the wire 33 is electrically connected to the battery 31, and the other end is electrically connected to the end of the conductive piece 32 away from the atomization core 20. That is, the power supply assembly 30 achieves electrical connection between the conductive piece 32 and the battery 31 by arranging the wire 33.

[0052] For example, the conductive piece 32 is a needle.

[0053] The aerosol generating device provided by the embodiments of the present application comprises an atomization seat assembly 10, an atomization core 20 having an atomization surface 20a and a liquid suction surface 20b arranged oppositely, an air outlet channel 54a, and a power supply assembly 30. The atomization seat assembly 10 is formed with an atomization space and a liquid storage cavity 10b for storing an aerosol generating substrate. The atomization core 20 is arranged in the atomization space. The atomization surface 20a and the atomization space facing the atomization surface 20a define an atomization cavity 10a. The liquid storage cavity 10b is in communication with the liquid suction surface 20b. That is, the aerosol in the liquid storage cavity 10b can be guided to the liquid suction surface 20b of the atomization core 20. The atomization core 20 is used for atomizing the aerosol generating substrate to generate an aerosol. The air outlet channel 54a is in communication with the atomization cavity 10a and is used for discharging the aerosol in the atomization cavity 10a. The aerosol generating device 100 of the embodiments of the present application is used for improving the taste of the aerosol by arranging the atomization surface 20a to face the air outlet channel 54a. Further, the electrically conductive member 32 is arranged on the side of the atomization surface 20a facing the air outlet channel 54a and extends towards the air outlet channel 54a. The battery 31 is electrically connected to the atomization core 20 through the electrically conductive member 32. The electrically conductive member 32 and the heating conductive film arranged on the atomization surface 20a are located on the same side of the atomization core 20. Therefore, it is not necessary to drill holes or print a circuit on the side of the atomization core 20, which simplifies the structure and processing technology of the atomization core 20. That is, the aerosol generating device 100 provided by the embodiments of the present application can improve the taste of the aerosol while reducing the difficulty of the manufacturing process and reducing the manufacturing cost. In addition, since it is not necessary to print a circuit on the side or bottom surface of the atomization core 20, the flatness of the side or bottom surface of the atomization core 20 is improved, which is conducive to improving the sealing performance of the atomization core 20.

[0054] Exemplarily, please refer to Figure 2 to Figure 8 The atomization seat assembly 10 comprises an atomization top seat 11 and an atomization bottom seat 12.

[0055] It should be noted that the forming mode of the liquid storage cavity 10b is not limited herein. Exemplarily, in some embodiments, please refer to Figure 2 The atomization bottom seat 12 is arranged on the bottom side of the atomization top seat 11 and defines the liquid storage cavity 10b with the atomization top seat 11.

[0056] Of course, in another embodiment, the aerosol generating device 100 comprises a housing assembly 50. The liquid storage cavity 10b can also be defined between the atomization seat assembly 10 and the housing assembly 50.

[0057] Exemplarily, please refer to Figure 2 and Figure 10 The atomization top seat 11 comprises a top seat top wall 111, a cylinder 113, and a top seat side wall 112 surrounding the top seat top wall 111. The top seat top wall 111 and the top seat side wall 112 surround to form a cavity. At least part of the structure of the atomization bottom seat 12 is arranged in the cavity and defines the liquid storage cavity 10b with the atomization top seat 11.

[0058] The appearance profile of the top wall 111 of the top seat and the top seat side wall 112 surrounding the top wall 111 determines the appearance profile of the atomizing top seat 11. The cylinder 113 is arranged inside the cavity.

[0059] The arrangement of at least part of the structure of the atomizing bottom seat 12 in the cavity means that the atomizing bottom seat 12 can be partially arranged in the cavity of the atomizing top seat 11, or the entire structure can be arranged in the cavity.

[0060] Of course, in other embodiments, the atomizing bottom seat 12 can also be in abutment with the atomizing top seat 11 without extending into the cavity.

[0061] Specifically, in some embodiments, referring to Figure 2 and Figure 5 , the atomizing bottom seat 12 comprises a surrounding edge 12c surrounding the outer side of the atomizing bottom seat 12, and is in abutment with the top seat side wall 112 through the surrounding edge 12c to achieve the connection of the atomizing bottom seat 12 and the atomizing top seat 11.

[0062] Of course, in other embodiments, the atomizing bottom seat 12 can also be in abutment with the top seat side wall 112 through the outer side wall of the atomizing bottom seat 12 to achieve the connection of the atomizing bottom seat 12 and the atomizing top seat 11.

[0063] It should be noted that the specific connection mode of the atomizing bottom seat 12 and the atomizing top seat 11 is not limited here, for example, it can be interference fit, clamping, etc. It is beneficial to realize the disassembly of the atomizing bottom seat 12 and the atomizing top seat 11, improve the assembly efficiency, and improve the use convenience.

[0064] In the related art, the aerosol generating device fills the liquid at the bottom of the liquid storage cavity, and after assembling the atomizing core, the liquid flows into the atomizing core, which is easy to form large bubbles in the liquid storage cavity. When the temperature rises, the volume of the bubbles expands to squeeze the aerosol generating substrate out of the liquid storage cavity, causing liquid leakage.

[0065] And the aerosol generating device of the embodiment of the present application, referring to Figure 2 and Figure 10 The atomizing top seat 11 is provided with a liquid injection port 111a penetrating the top wall 111 of the top seat. That is, by arranging the liquid injection port 111a on the top wall 111 of the top seat, the liquid injection can be performed after the atomizing core 20 is assembled, that is, the aerosol generating substrate is injected into the liquid storage cavity 10b through the liquid injection port 111a, so as to reduce the bubbles in the liquid storage cavity 10b, and further improve the situation that the volume of the bubbles expands to squeeze the aerosol generating substrate out of the liquid storage cavity 10b when the temperature rises.

[0066] Exemplarily, referring to Figure 2 and Figure 6The atomization seat assembly 10 comprises a sealing plug 13. After liquid injection is performed on the aerosol generating device 100 through the liquid injection port 111a, the sealing plug 13 is inserted into the liquid injection port 111a to seal the liquid storage cavity 10b, so as to avoid leakage of the aerosol generating substrate from the liquid injection port 111a during use or transportation.

[0067] For example, referring to Figure 2 and Figure 5 The atomization seat assembly 10 comprises a sealing member 15 clamped between the atomization base 12 and the atomization top seat 11, used to seal the assembly gap between the atomization base 12 and the atomization top seat 11, improve the sealing performance of the liquid storage cavity 10b, avoid the aerosol generating substrate in the liquid storage cavity 10b from flowing out of the assembly gap between the atomization base 12 and the atomization top seat 11, so as to avoid affecting the service life and user experience of the aerosol generating device 100.

[0068] The material of the sealing member 15 is not limited, for example, silicone, rubber, etc.

[0069] For example, referring to Figure 2 to Figure 8 The cylinder 113 is arranged inside the cavity, one end of the cylinder 113 is connected with the top wall 111 of the top seat, and the other end extends towards the atomization base 12. The inside of the cylinder 113 forms a connecting channel 113a, the connecting channel 113a has oppositely arranged first and second openings 113b and 113c. The first opening 113b penetrates through the top wall 111 of the top seat, and the second opening 113c penetrates through the bottom wall of the cylinder 113. The second opening 113c communicates the connecting channel 113a with the liquid storage cavity 10b. The atomization core 20 is arranged at the bottom of the connecting channel 113a, and the atomization surface 20a faces the first opening 113b.

[0070] That is, the atomization top seat 11 is formed by arranging the top wall 111 of the top seat, the cylinder 113, and the side wall 112 of the top seat surrounding the top wall 111, so that the top wall 111 and the side wall 112 of the top seat surround to form a cavity. The inside of the cylinder 113 forms a connecting channel 113a, that is, the atomization top seat 11 forms two independent spaces of the cavity and the connecting channel 113a. The two independent spaces are communicated through the second opening 113c. In this way, the space of the atomization top seat 11 can be fully utilized, and the structural compactness of the atomization seat assembly 10 can be improved.

[0071] When the atomization base 12 is arranged at the bottom side of the atomization top seat 11 and defines the liquid storage cavity 10b with the atomization top seat 11, the inside of the cylinder 113 forms a connecting channel 113a. By arranging the atomization core 20 at the bottom of the connecting channel 113a, that is, the atomization cavity 10a is arranged in the connecting channel 113a. In this way, the aerosol generating substrate in the liquid storage cavity 10b can be guided to the atomization core 20 through the second opening 113c.

[0072] The atomization core 20 is arranged at the bottom of the connecting channel 113a, for example, the atomization core 20 is arranged on the bottom wall of the column 113, that is, the atomization core 20 is overlapped at the edge of the second opening 113c, and the bottom wall of the column 113 bears the atomization core 20.

[0073] Exemplarily, please refer to Figure 2 to Figure 8 , the atomization seat assembly 10 comprises a liquid guide 60 arranged at the bottom of the atomization base 12 and located at the second opening 113c, and the liquid guide 60 is used to guide the aerosol generating substrate to the atomization core 20. Specifically, the liquid guide 60 extends into the second opening 113c and abuts against the substrate. Of course, the substrate can also extend into the second opening 113c and abut against the liquid guide 60.

[0074] The liquid guide 60 can be a liquid guide cotton formed by one or a combination of non-woven fabric, linen or wood pulp cotton. Of course, it can also be other liquid-conducting materials. The liquid guide cotton is made of cotton fiber material, which can stably store and quickly guide the aerosol generating substrate in the liquid storage cavity 10b to the atomization core 20 for atomization and aerosol generation.

[0075] The arrangement of the liquid guide 60 can guide the aerosol generating substrate at the bottom of the liquid storage cavity 10b to the atomization core 20 for heating and atomization to generate aerosol even if the liquid level of the aerosol generating substrate is lower than the atomization core 20, thereby improving the utilization rate of the aerosol generating substrate.

[0076] It should be noted that there are various ways to form the atomization cavity 10a, exemplarily, please refer to Figure 2 to Figure 9 The atomization seat assembly 10 comprises a mounting seat 14 arranged in the connecting channel 113a, and the mounting seat 14 and the inner wall of the connecting channel 113a define an atomization space. That is, the atomization seat assembly 10 is formed by arranging the column 113, the mounting seat 14, and arranging the mounting seat 14 in the connecting channel 113a of the column 113 to form the space between the mounting seat 14 and the inner wall of the connecting channel 113a as the atomization space.

[0077] The atomization cavity 10a is in communication with the first opening 113b, that is, the air outside can enter the atomization cavity 10a through the first opening 113b, that is, it is beneficial for the air outside to enter the atomization cavity 10a from the top of the atomization cavity 10a.

[0078] Please refer to Figure 2 to Figure 8 The conductive member 32 is arranged in the mounting seat 14, that is, the conductive member 32 can be arranged on the mounting seat 14 and used to realize electrical connection with the atomization core 20.

[0079] The specific structure of the mounting seat 14 is not limited here, as long as it can jointly define the atomization cavity 10a with the inner wall of the connecting channel 113a, exemplarily, in some embodiments, please refer toFigure 2 to Figure 9 The mounting seat 14 includes a first portion 141 and a second portion 142. The first portion 141 is clamped between the atomization core 20 and the inner wall of the connecting channel 113a. The second portion 142 is located above the atomization core 20, and the conductive member 32 penetrates the second portion 142. That is, there is a certain space between the first portion 141 and the second portion 142, for example, the first portion 141 and the second portion 142 are spaced apart along the extension direction of the connecting channel 113a, and together define the atomization cavity 10a with the inner wall of the connecting channel 113a.

[0080] The first portion 141 is clamped between the atomization core 20 and the inner wall of the connecting channel 113a. There may be an installation gap between the atomization core 20 and the inner wall of the connecting channel 113a, and the first portion 141 clamped in the installation gap between the atomization core 20 and the inner wall of the connecting channel 113a can seal the installation gap between the atomization core 20 and the inner wall of the connecting channel 113a to a certain extent. For example, the atomization core 20 is interference fitted in the first portion 141, and the first portion 141 is interference fitted in the column 113, which facilitates assembly and has good sealing performance.

[0081] It should be noted that the first portion 141 and the second portion 142 can be in abutment, that is, the second portion 142 is supported on the first portion 141. Of course, the first portion 141 and the second portion 142 can also be spaced apart.

[0082] Exemplarily, the first portion 141 and the second portion 142 are of a split structure. This facilitates assembly and improves assembly efficiency.

[0083] Of course, the mounting seat 14 can also be of an integral structure, for example, integrally injection molded. The integral mounting seat 14 can reduce the number of parts and assembly time, and improve assembly efficiency.

[0084] Exemplarily, the mounting seat 14 can be made of plastic or silicone.

[0085] Exemplarily, the aerosol-generating device 100 includes an air exchange channel. The aerosol-generating substrate in the liquid storage cavity 10b is guided to the atomization core 20 and heated and atomized in the atomization cavity 10a to generate aerosol. The aerosol is discharged through the end of the air outlet channel 54a for the user to smoke. After the aerosol-generating substrate in the liquid storage cavity 10b is consumed, a negative pressure is formed. Under the action of atmospheric pressure, external air enters the liquid storage cavity 10b through the air exchange channel to balance the pressure in the liquid storage cavity 10b, which is conducive to continuously guiding the aerosol-generating substrate in the liquid storage cavity 10b to the atomization core 20 to achieve continuous atomization.

[0086] Exemplarily, please refer to Figure 2 , Figure 4 andFigure 10 The inner wall of the columnar cylinder 113 is provided with a ventilation groove 113d, one end of the ventilation groove 113d extending to the second opening 113c and the other end extending to the atomization cavity 10a, that is, the ventilation groove 113d communicates the atomization cavity 10a and the second opening 113c.

[0087] When the mounting seat 14 and the atomization core 20 are assembled to the connecting channel 113a, a ventilation channel is defined between the mounting seat 14 and the atomization core 20 and the ventilation groove 113d, and the ventilation channel communicates the liquid storage cavity 10b and the atomization cavity 10a.

[0088] During smoking, the air outlet channel 54a generates negative pressure, and the aerosol in the atomization cavity 10a is sucked into the air outlet channel 54a under the action of the negative pressure, and then enters the user's oral cavity. The atomization cavity 10a generates negative pressure, and the air in the external environment is supplemented into the atomization cavity 10a under the action of the negative pressure, realizing continuous smoking of the aerosol.

[0089] Exemplarily, please refer to Figure 2 and Figure 4 The end of the ventilation groove 113d away from the second opening 113c is a ventilation inlet 113e, and the ventilation inlet 113e is higher than the atomization surface 20a. It can be understood that, since the atomization surface 20a is arranged towards the air outlet channel 54a, that is, upwards, and the ventilation inlet 113e is in the atomization cavity 10a and higher than the atomization surface 20a, a part of the aerosol generating substrate in the ventilation groove 113d can be sucked out to the atomization cavity 10a and flow to the atomization core 20 under the negative pressure in the atomization cavity 10a during suction, forming auxiliary liquid supply.

[0090] The number of the ventilation grooves 113d is not limited, which can be one or multiple. Exemplarily, the number of the ventilation grooves 113d is multiple. In this way, the arrangement of multiple ventilation grooves 113d not only facilitates the airflow in the atomization cavity 10a to be supplemented into the atomization cavity 10a through the ventilation grooves 113d, but also can avoid the blockage of any ventilation groove 113d to affect the ventilation and thus the suction.

[0091] In a specific embodiment, please refer to Figure 4 The number of the ventilation grooves 113d is two, and the two ventilation grooves 113d are located on opposite sides of the columnar cylinder 113, which is beneficial to the uniformity of ventilation.

[0092] In the related art, the air inlet channel generally enters from the bottom of the atomization cavity, and due to temperature changes, the aerosol generating substrate overflowing from the ventilation channel and the condensate formed during suction are easy to flow out through the air inlet channel, causing liquid leakage, reducing the utilization rate of the aerosol generating substrate and reducing the user experience.

[0093] And the aerosol generating device of the embodiment of the present application, please refer to Figure 2 and Figure 6The gap between the atomization top seat 11 and the shell assembly 50 forms an air inlet channel (see the continuous dashed line with arrows shown in Figure 6 The first opening 113b communicates with the outside through the air inlet channel. That is, the air from the outside can enter the connection channel 113a through the air inlet channel and the first opening 113b in sequence, and then enter the atomization cavity 10a. Since the first opening 113b penetrates the top wall 111 of the top seat, that is, the air in the air inlet channel enters the atomization cavity 10a through the first opening 113b at the top, which is conducive to the air from the outside entering the atomization cavity 10a from the top of the atomization cavity 10a.

[0094] Therefore, when the aerosol generating substrate overflowing from the air passage and the condensate formed by condensation during suction do not flow out through the air inlet channel to form liquid leakage. Since the atomization surface 20a is arranged upward, the aerosol generating substrate overflowing from the air passage will flow to the atomization core 20 to form auxiliary liquid supply; the condensate formed by condensation during suction will also flow to the atomization core 20 for secondary atomization, thereby avoiding liquid leakage while improving the utilization rate of the aerosol generating substrate.

[0095] Exemplarily, please refer to Figure 2 The shell assembly 50 includes a top cover 51, a shell 52, and a bottom cover 53. The atomization seat assembly 10 is arranged in the shell assembly 50.

[0096] The gap between the atomization top seat 11 and the shell assembly 50 forms an air inlet channel, which can be a gap between the top wall 111 of the top seat and the shell assembly 50, or a gap between the side wall 112 of the top seat and the shell assembly 50, or a gap between the top wall 111 of the top seat and the shell assembly 50.

[0097] Please refer to Figure 2 and Figure 6 The shell assembly 50 is provided with an air inlet 53a, and the air from the outside enters the air inlet channel through the air inlet 53a. It can be understood that the air inlet 53a can be arranged on one of the top cover 51, the shell 52, or the bottom cover 53. Of course, multiple of the top cover 51, the shell 52, and the bottom cover 53 can also be provided with air inlets 53a.

[0098] Exemplarily, the top cover 51 and the shell 52 are of a split structure. This is conducive to the assembly of other components of the aerosol generating device 100.

[0099] Of course, the top cover 51 and the shell 52 can also be of an integrated structure, for example, integrally injection molded. The integrated top cover 51 and the shell 52 can reduce the number of components, reduce the assembly time, and improve the assembly efficiency.

[0100] Exemplarily, the bottom cover 53 and the shell 52 are in a split structure. This facilitates assembly of other components of the aerosol-generating device 100.

[0101] Of course, the bottom cover 53 and the shell 52 can also be in an integrated structure, for example, integrally injection molded. The integrated top cover 51 and the shell 52 can reduce the number of components, reduce assembly time, and improve assembly efficiency.

[0102] In a specific embodiment, the top cover 51, the shell 52, and the bottom cover 53 are in a split structure, and are connected and fixed through clamping or interference fit between the top cover 51, the shell 52, and the bottom cover 53. This connection structure is simple and facilitates disassembly and assembly.

[0103] It should be noted that the specific manner of using the aerosol-generating device 100 is not limited herein. For example, a user can directly smoke aerosol through the shell assembly 50, that is, the top cover 51 of the shell assembly 50 is in the structure of a mouthpiece, or can smoke aerosol through an additional mouthpiece cooperating with the shell assembly 50.

[0104] Exemplarily, please refer to Figure 2 , the power supply assembly 30 includes a wire 33, one end of the wire 33 is electrically connected with the battery 31, and the other end extends into the connecting channel 113a through the air inlet channel and the first opening 113b in sequence, and is electrically connected with the end of the conductive piece 32 away from the atomizing core 20. The power supply assembly 30 is provided with the wire 33 to realize electrical connection between the conductive piece 32 and the battery 31. That is, by arranging the atomizing face 20a to face the air outlet channel 54a, the taste of the aerosol is improved. Secondly, by arranging the conductive piece 32 and the wire 33 on the side of the atomizing face 20a facing the air outlet channel 54a and extending toward the air outlet channel 54a, that is, the wire 33 extends into the connecting channel 113a through the air inlet channel and the first opening 113b in sequence and is electrically connected with the end of the conductive piece 32 away from the atomizing core 20, the wire 33 does not need to pass through the lower surface of the base body from the atomizing face 20a of the base body to connect the battery 31. In this way, a common atomizing core 20 can be used, and a special atomizing core 20 with a metal wire 33 does not need to be designed, which simplifies the structure and processing technology of the atomizing core 20, improves the taste of the aerosol, and reduces the manufacturing process difficulty and manufacturing cost.

[0105] Exemplarily, please refer to Figure 2 , Figure 3 and Figure 10 , the circumferential outer side of the top seat side wall 112 is formed with a skirt 114, and the skirt 114 is lapped on the top end of the shell 52, which can realize positioning of the atomizing seat assembly 10.

[0106] Exemplarily, please refer to Figure 2 to Figure 8The shell assembly 50 comprises an air outlet tube 54 having an air outlet channel 54a, at least a part of the air outlet tube 54 extends into the connecting channel 113a so that the air outlet channel 54a is in communication with the atomization cavity 10a. Specifically, the air outlet tube 54 is arranged on the top cover 51.

[0107] Please refer to Figure 2 and Figure 9 The top of the mounting seat 14 is formed with a relief opening 14c in communication with the atomization cavity 10a, and a part of the structure of the air outlet tube 54 extends into the relief opening 14c or abuts against the top of the mounting seat 14, so that the air outlet channel 54a is in communication with the atomization cavity 10a through the relief opening 14c.

[0108] It should be noted that there are various ways for the atomization cavity 10a to communicate with the first opening 113b. Exemplarily, in some embodiments, please refer to Figure 5 The gap between the mounting seat 14 and the inner wall of the column 113 forms a first air passage 10c, and the atomization cavity 10a communicates with the first opening 113b through the first air passage 10c. For example, one of the mounting seat 14 and the inner wall of the column 113 forms an air passage groove, so that the gap between the mounting seat 14 and the inner wall of the column 113 forms the first air passage 10c.

[0109] In this way, when smoking, a negative pressure is generated in the air outlet channel 54a and the atomization cavity 10a, and the air in the air inlet channel enters the atomization cavity 10a through the first air passage 10c and carries the aerosol out to the end of the air outlet channel 54a for the user to use.

[0110] The number of the first air passage 10c is not limited and can be one or multiple. Exemplarily, the number of the first air passage 10c is multiple. In this way, the arrangement of multiple first air passages 10c not only facilitates the transmission of external air to the atomization cavity 10a through the first air passage 10c to improve the atomization efficiency, but also avoids the blockage of any first air passage 10c to affect the suction.

[0111] In a specific embodiment, please refer to Figure 5 The number of the first air passage 10c is two, and the two first air passages 10c are located on opposite sides of the mounting seat 14, which is beneficial to the uniformity of air intake.

[0112] It can be understood that the external air can enter the connecting channel 113a in sequence through the air inlet channel and the first opening 113b, and the air in the connecting channel 113a directly enters the atomization cavity 10a through the first air passage 10c.

[0113] Of course, the air in the connecting channel 113a does not directly enter the atomization cavity 10a through the first air passage 10c. Exemplarily, please refer to Figure 7 to Figure 9, the mounting seat 14 is formed with a second air passage 14a and a third air passage 14b, the first air passage 10c, the second air passage 14a and the third air passage 14b are communicated in sequence, the extending directions of the first air passage 10c and the third air passage 14b are the same as the extending direction of the air outlet passage 54a, the extending direction of the second air passage 14a is perpendicular to the extending direction of the air outlet passage 54a, and the third air passage 14b is arranged towards the atomization face 20a. That is, the air in the connecting passage 113a enters the atomization cavity 10a in sequence through the first air passage 10c, the second air passage 14a and the third air passage 14b.

[0114] By arranging the first air passage 10c, the second air passage 14a and the third air passage 14b to be communicated in sequence, the direction and position of the air entering the atomization cavity 10a can be controlled, that is, the flow of the air is guided, and by arranging the third air passage 14b towards the atomization face 20a, the air outside can enter the atomization cavity 10a in a direction perpendicular to the atomization face 20a, so that the air outside can directly flow vertically to the atomization face 20a, and the atomization effect is improved.

[0115] The second air passage 14a can be formed on the first part 141, can be formed on the second part 142, or can be jointly defined between the first part 141 and the second part 142.

[0116] The third air passage 14b can be formed on the second part 142, or can be jointly defined between the first part 141 and the second part 142.

[0117] Exemplarily, the center line of the third air passage 14b coincides or substantially coincides with the center line of the atomization face 20a, the air outside enters the atomization cavity 10a towards the center of the atomization face 20a through the third air passage 14b, and the atomization effect is further improved.

[0118] In some other embodiments, the first air passage 10c can also not be formed by the gap between the mounting seat 14 and the inner wall of the column 113, but the first air passage 10c is formed in the interior of the mounting seat 14.

[0119] In some other embodiments, please refer to Figure 6The fourth air passage 32a is formed in the interior of the conductive member 32, and the atomization cavity 10a is communicated with the first opening 113b through the fourth air passage 32a. In this embodiment, the conductive member 32 is a hollow structure, so that the fourth air passage 32a is formed in the interior of the conductive member 32. The air outside can enter the connecting passage 113a through the air inlet passage, the first opening 113b, and the fourth air passage 32a in the interior of the conductive member 32 in sequence. The air in the connecting passage 113a enters the atomization cavity 10a through the fourth air passage 32a in the interior of the conductive member 32. By forming the fourth air passage 32a in the interior of the conductive member 32, the reliability of the air flow passage can be improved, and the structure of the mounting seat 14 is simplified.

[0120] In the related art, the aerosol generating device with the atomization surface of the atomization core upwardly arranged generally adopts bottom surface liquid supply.
