Description

Technical Field

[0001] This application relates to the field of aerosol generation equipment technology, specifically to an aerosol generation device and an aerosol generation equipment. Background Technology

[0002] Currently, common aerosol generation equipment typically includes a storage tank to store the aerosol matrix. However, this tank is usually fixed to the main body of the equipment, preventing users from replacing or reassembling it as needed, thus limiting its flexibility. While some related technologies offer aerosol generation equipment with external storage tanks, improving flexibility to some extent, these typically place the tank on one side of the housing in the width direction and the air intake channel on the other. This arrangement has drawbacks. When the overall size of the equipment is limited (e.g., length, width, and height are restricted), it's difficult to further expand the storage tank in the width direction to ensure sufficient space for the air intake channel. Increasing the width of the storage tank or placing tanks on both sides of the housing in the width direction further compresses the space for the air intake channel, making it difficult to meet normal operating air intake requirements.

Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0037] The aerosol generating device provided in this application can be assembled and used with a detachable liquid storage tank. The aerosol generating device can hold a portion of the aerosol matrix and can also be equipped with a liquid storage tank to replenish the aerosol matrix as needed. The aerosol matrix is ​​heated and atomized by the atomizing core assembly in the atomizing chamber to generate an aerosol. The air inlet channel of the shell assembly can introduce external air into the atomizing core assembly, so that the air mixes with the aerosol and flows to the nozzle for inhalation.

[0038] For ease of description, in the following embodiments, the height direction of the aerosol generating device and the aerosol generating equipment is taken as the first direction, the width direction as the second direction, and the thickness direction as the third direction.

[0039] The following describes some embodiments of the aerosol generating apparatus and aerosol generating equipment provided in this application, with reference to the accompanying drawings.

[0040] An embodiment of the first aspect of this application provides an aerosol generating apparatus 100, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the aerosol generating device 100 includes a housing assembly 1 and an atomizing core assembly 2. The housing assembly 1 has an atomizing chamber 1124, an assembly portion 1125, and a nozzle 121; the atomizing chamber 1124 can contain an aerosol matrix, and at least a portion of the atomizing core assembly 2 is disposed within the atomizing chamber 1124 to heat the aerosol matrix; the nozzle 121 is arranged along a first direction with the atomizing chamber 1124, and the nozzle 121 is disposed at one end of the atomizing chamber 1124 and communicates with the atomizing core assembly 2 so that the aerosol gas generated in the atomizing core assembly 2 can flow out through the nozzle 121. The assembly part 1125 is located on the side of the atomizing chamber 1124 in the second direction. The assembly part 1125 has at least one assembly space 1127 on the side facing the nozzle 121 in the first direction for mounting the liquid storage chamber 510. The assembly space 1127 and the atomizing chamber 1124 are arranged along the second direction, which is perpendicular to the first direction. When the liquid storage chamber 510 is installed in the assembly space 1127, the assembly part 1125 can be detachably connected to the liquid storage chamber 510. A liquid guiding channel 114 and an air inlet channel 123 are formed inside the housing assembly 1. One end of the liquid guiding channel 114 has a liquid inlet port 1126, and the other end of the liquid guiding channel 114 communicates with the atomizing chamber 1124. When the liquid storage chamber 510 is connected to the assembly part 1125, as... Figure 5 and Figure 6 In the example, the liquid inlet 1126 can communicate with the liquid storage tank 510, so that the aerosol matrix in the liquid storage tank 510 can enter the atomizing chamber 1124 through the liquid inlet 1126 and the liquid guiding channel 114, thereby replenishing the aerosol matrix in the atomizing chamber 1124. The third direction is perpendicular to the first and second directions, such as... Figure 7 In the example, the air intake channel 123 is disposed on at least one side of the atomizing chamber 1124 in the third direction. One end of the air intake channel 123 has an air intake hole 124, and the other end of the air intake channel 123 is connected to the atomizing core assembly 2 so that external air can enter the atomizing core assembly 2 through the air intake channel 123 and mix with the generated aerosol to form aerosol gas.

[0041] It should be noted that the aerosol generating device 100 in this embodiment can be externally connected to one or more liquid storage tanks 510, for example... Figure 4 The two external liquid storage chambers 510 shown in the figure can be installed on both sides of the atomizing chamber 1124 in the second direction to increase the liquid replenishment. The housing assembly 1 adopts a similar inverted T-shaped structure to match the liquid storage chambers 510 on both sides. Of course, the atomizing chamber 1124 can also be set on only one side of the atomizing chamber 1124 in the second direction according to the needs of use.

[0042] It is understandable that in existing aerosol generating devices with externally connected liquid storage tanks, the liquid storage tank is usually located on one side of the housing in the width direction, and the air inlet channel 123 is located on the other side of the housing in the width direction. However, in actual production, the overall size of the equipment is subject to certain limitations (e.g., the length, width, and height are limited to a certain range). In this case, if sufficient space is required for the air inlet channel, it is difficult to further expand the liquid storage tank in the width direction. If the size of the liquid storage tank in the second direction is further increased to increase the liquid storage tank capacity, or if liquid storage tanks are set on both sides of the atomizing chamber in the second direction, the space of the air inlet channel will be further compressed, making it difficult to meet the air intake requirements during normal use.

[0043] The aerosol generating device in this embodiment, through structural improvements and optimizations, can make full use of the internal three-dimensional space of the shell assembly to arrange the liquid storage tank and air intake channel more rationally, while meeting the requirements of the external liquid storage tank. This ensures that the air intake channel and the liquid storage tank are located in two mutually perpendicular directions relative to the atomizing chamber, preventing mutual interference. Within a limited space, it can both expand the capacity of the liquid storage tank in the second direction (e.g., increase the size of the liquid storage tank in the second direction or set liquid storage tanks on both sides of the shell) and ensure that the air intake channel has sufficient space to meet the air intake requirements during normal use.

[0044] Depending on the actual usage needs, air intake channels 123 can be set on both sides of the third-direction upward atomizing chamber 1124, or air intake channels 123 can be set on only one side of the atomizing chamber 1124. This will not occupy the space in the second direction and will not affect the size of the liquid storage chamber.

[0045] In further embodiments of this application, such as Figures 1 to 5As shown, the aerosol generating device 100 includes a detachably connected housing base 11 and an upper housing 12. An atomizing chamber 1124 and an assembly portion 1125 are both located on the housing base 11. The atomizing chamber 1124 extends along a first direction, and the assembly portion 1125 protrudes relative to the atomizing chamber 1124 along a second direction. A liquid guiding channel 114 is located within the housing base 11, and the liquid inlet 1126 of the liquid guiding channel 114 extends to the end of the assembly portion 1125 facing the nozzle 121. Figures 5 to 7 In the example shown, at least a portion of the upper housing 12 is connected to the end of the atomizing chamber 1124 away from the liquid guiding channel 114. The upper housing 12 includes a mouthpiece 121 and a side shell portion 122, which are arranged along a third direction. In the first direction, the mouthpiece 121 is located at the end of the atomizing chamber 1124 away from the liquid guiding channel 114. The side shell portion 122 is located on at least one side of the atomizing chamber 1124 in the third direction and extends along the first direction to the housing base 11. An air intake channel 123 is formed inside the side shell portion 122 so that the air intake channel 123 communicates with the atomizing core assembly 2 through the housing base 11. Compared to the one-piece housing assembly 1, the use of a detachably connected housing base 11 and side shell portion 122 facilitates the processing and manufacturing of each component and also facilitates assembly.

[0046] The side shell portion 122 is not limited to, for example, Figure 1 and Figure 7 The cylindrical structure shown can also be configured into other shapes as needed, as long as it can form the air intake channel 123. For example, Figure 8 In the example, the side shell 122 facing the atomizing chamber 1124 can be configured as an arc-shaped structure that adapts to the side wall of the atomizing chamber 1124, so that the side shell 122 can fit tightly with the atomizing chamber 1124 and increase the contact area between the two.

[0047] Furthermore, in a specific implementation, such as Figures 1 to 7 As shown, an air inlet 124 is provided on the side wall of the side shell 122 to connect the air intake channel 123 with the external space, so that external air can pass through the air inlet 124 and enter the air intake channel 123.

[0048] Furthermore, such as Figure 1 and Figure 7In the example shown, the air inlet 124 is located on the side wall of the side shell 122 on the side away from the atomizing chamber 1124 in the third direction, and in the first direction, the air inlet 124 is close to the top wall of the side shell 122. During use, the heat generated by the atomizing core assembly 2 heating the aerosol is conducted to the side wall of the atomizing chamber 1124. When external air enters the air intake channel 123, it can exchange heat with the side wall of the atomizing chamber 1124, thereby increasing the airflow temperature and preventing cold air from directly flowing into the atomizing core assembly 2 and affecting the atomization effect. By configuring the air inlet 124 in this embodiment, the space within the side shell 122 can be fully utilized, extending the airflow path and allowing the airflow to absorb as much heat as possible from the atomizing chamber 1124 as it flows towards the atomizing core assembly 2, achieving heat recovery and utilization, and helping to reduce energy consumption.

[0049] It should be noted that in practical applications, the air inlet 124 can also be set on the top wall of the side shell 122 according to the needs of use. Alternatively, if the aerosol generating device 100 is provided with only one liquid storage chamber 510, the air inlet 124 can also be set on the side wall of the side shell 122 away from the liquid storage chamber 510 along the second direction. The specific choice can be made according to the assembly of the aerosol generating device 100 and the atomizing chamber 1124, which will not be elaborated here.

[0050] Furthermore, in a specific example, such as Figures 4 to 6 As shown, in the third direction, the side wall of the side shell 122 away from the atomizing chamber 1124 extends to the outer edge of the assembly space 1127. When the liquid storage chamber 510 is installed into the assembly space 1127, the outer wall of the side shell 122 in the third direction is flush with the outer wall of the liquid storage chamber 510 to ensure the overall appearance consistency of the equipment.

[0051] It is understandable that in practical applications, the overall size of the device usually needs to be set according to design requirements, such as length, width, and thickness. Under the premise of overall size constraints, the liquid storage chamber 510 and the shell assembly 1 maintain the same size (i.e., thickness) in the third direction. Since the upper shell 12 only needs to accommodate the atomizing chamber 1124, although the available space in the second direction of the upper shell 12 will be compressed to near the minimum within the allowable range in order to maximize the capacity of the liquid storage chamber 510, a certain amount of empty space will still be formed in the third direction of the upper shell 12.

[0052] In this embodiment, the side shell 122 can be formed in the free space in the third direction of the existing upper shell 12. During the production process, only the corresponding drilling operation is required to naturally form the air intake channel 123 that allows gas flow. No additional design and processing are required, which simplifies the structure and processing, and helps to further improve production efficiency and reduce production costs.

[0053] In further embodiments of this application, such as Figures 5 to 9 As shown, the housing base 11 includes a base bottom shell 111, a base top cover 112, and a first sealing member 113. The end of the base bottom shell 111 facing the nozzle 121 in the first direction is an open structure (i.e., an open-top structure). The first sealing member 113 and the base top cover 112 are both disposed inside the base bottom shell 111, and the first sealing member 113 is located between the base top cover 112 and the bottom wall of the base bottom shell 111 to provide a sealing function. At the same time, the circumference of the base top cover 112 is surrounded by the side wall of the base bottom shell 111, so that the base top cover 112 and the side wall of the base bottom shell 111 form a groove structure. The atomizing chamber 1124 and the liquid inlet 1126 are both located on the base top cover 112. The above-mentioned groove structure forms an assembly part 1125 to facilitate assembly and connection with the liquid storage chamber 510. The first sealing member 113 and the base top cover 112 together form a liquid guiding channel 114, which is connected to the atomizing chamber 1124. The first sealing member 113 and the base bottom shell 111 together form an air guiding chamber 115. Correspondingly, the base top cover 112 has a first air guiding hole 1121 at a position corresponding to the air inlet channel 123. The first sealing member 113 has a second air guiding hole 1131 and a third air guiding hole 1132. The second air guiding hole 1131 connects the first air guiding hole 1121 and the air guiding chamber 115, and the third air guiding hole 1132 connects the air guiding chamber 115 and the atomizing core assembly 2. This allows the air in the air inlet channel 123 to pass through the first air guiding hole 1121, the second air guiding hole 1131 and the third air guiding hole 1132 in sequence and enter the atomizing core assembly 2. The base shell 111 has a conductive element 1112 at the end away from the mouthpiece 121 in the first direction, which is electrically connected to the atomizing core assembly 2. The conductive element 1112 is electrically connected to the power supply assembly 3 to supply power to the atomizing core assembly 2. The first sealing element 113 may be made of silicone.

[0054] Furthermore, in a specific example, such as Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11As shown, in the housing base 11, the base top cover 112 is provided with a first groove 1122 and a second groove 1123 at one end of the base top cover 112 facing the first seal 113 along the first direction. The first groove 1122 is located inside the second groove 1123, and the sidewalls of the first groove 1122 and the sidewalls of the second groove 1123 both extend along the first direction. Correspondingly, the first seal 113 is provided with a third groove 1133 at one end of the base top cover 112 in the first direction. The third groove 1133 is provided corresponding to the first groove 1122. The sidewall of the third groove 1133 extends along the first direction and forms a mating fit with the first groove 1122, so that the third groove 1133 and the first groove 1122 form a liquid guiding channel 114. The liquid inlet 1126 is located on the top cover 112 of the base, corresponding to the liquid guiding channel 114. The first air guide hole 1121 is located in the third direction between the first groove 1122 and the second groove 1123, corresponding to the air inlet channel 123. The second air guide hole 1131 is located on the first seal 113 outside the liquid guiding channel 114, corresponding to the position between the first groove 1122 and the second groove 1123 of the top cover 112 of the base, so that the first air guide hole 1121 can communicate with the second air guide hole 1131. The first sealing member 113 has a fourth groove 1134 at one end facing away from the base top cover 112 along the first direction. The sidewall of the fourth groove 1134 extends along the first direction and is in contact with the inner wall of the base bottom shell 111 to form an air guide cavity 115. The second air guide hole 1131 communicates with the air guide cavity 115, and the third air guide hole 1132 is correspondingly provided with the atomizing chamber 1124. The air guide cavity 115 is connected to the atomizing core assembly 2 through the third air guide hole 1132. Air entering the air intake channel 123 through the air inlet hole 124 can pass through the first air guide hole 1121 and the second air guide hole 1131 in sequence to enter the air guide cavity 115, and then enter the atomizing core assembly 2 through the third air guide hole 1132.

[0055] By setting the first groove 1122 and the second groove 1123 on the base top cover 112, and the third groove 1133 and the fourth groove 1134 on the first seal 113, independent liquid guiding channels 114 and air guiding chambers 115 can be formed when the base top cover 112, the first seal 113 and the base bottom shell 111 are assembled, so as to realize liquid inlet and air inlet respectively. At the same time, during the assembly operation, the first groove 1122, the second groove 1123, the third groove 1133 and the fourth groove 1134 can also be used for positioning, so as to accurately dock and assemble.

[0056] Specifically, in a particular example, such as Figures 8 to 11In the example, a first air guide hole 1121 is provided on at least one side of the liquid guiding channel 114 along a third direction on the top cover 112 of the base, and the first air guide hole 1121 is a strip-shaped hole extending along a second direction. Since the first air guide hole 1121 and the upper air inlet channel 123 are correspondingly located on the outer side of the liquid guiding channel 114 in the third direction, but due to the limited size in the third direction, setting the first air guide hole 1121 as a strip-shaped hole extending along the second direction can fully utilize the existing space and increase the flow area of ​​the first air guide hole 1121. Preferably, as shown... Figure 10 and Figure 11 In the example, on the third-party upward direction, the liquid guiding channel 114 has first air guiding holes 1121 on both sides, which can further increase the air intake.

[0057] In a specific example, such as Figures 8 to 11 In the example, a second vent hole 1131 is provided on at least one side of the liquid guiding channel 114 along the second direction on the first sealing member 113. This allows the second vent hole 1131 and the first vent hole 1121 to be staggered in the height direction, forming a meandering channel. This extends the airflow path and prevents condensate in the air guiding chamber 115 from directly passing through the second vent hole 1131 and the first vent hole 1121 into the air intake channel 123, thus providing a certain degree of leak prevention. The second vent hole 1131 is configured as a strip-shaped hole extending along the third direction, which fully utilizes the existing space and further increases the flow area of ​​the second vent hole 1131. Preferably, as shown... Figure 10 and Figure 11 In the example, in the second direction, the liquid guiding channel 114 has a second air guiding hole 1131 on both sides, which can further increase the air intake.

[0058] Furthermore, in a specific example, a first protrusion structure can be provided on the edge of the first air guide hole 1121 facing the first seal 113. By providing the first protrusion structure to extend circumferentially along the first air guide hole 1121, a flange-like structure is formed. When the aerosol generating device 100 is placed on its side or upside down, the first protrusion structure can act as a retaining structure to prevent the condensate adhering to the inner wall of the base top cover 112 from passing through the first air guide hole 1121 into the air intake channel 123, which helps to enhance the anti-leakage effect. Similarly, a second protruding structure can be provided on the edge of the first end of the second air guide hole 1131 facing away from the base top cover 112. This second protruding structure extends circumferentially along the second air guide hole 1131 to form a flange-like structure. When the aerosol generating device 100 is placed on its side or upside down, the second protruding structure acts as a retaining structure, preventing condensate adhering to the inner wall of the air guide cavity 115 from flowing directly through the second air guide hole 1131 to the first air guide hole 1121. Preferably, both the first and second protruding structures can be provided simultaneously to form double protection, further reducing the possibility of condensate leakage from the air inlet channel 123.

[0059] In further embodiments of this application, such as Figure 12 and Figure 13 As shown, the aerosol generating device 100 also includes a power supply component 3. The power supply component 3 is connected to the housing component 1 and can be electrically connected to the atomizing core component 2 to supply power to the atomizing core component 2, causing the atomizing core component 2 to heat up, thereby heating and atomizing the aerosol matrix to generate aerosol.

[0060] Furthermore, such as Figure 13 In the example shown, the power supply assembly 3 includes a power supply housing 31, a battery 32, and an electronic control board 33. Both the battery 32 and the electronic control board 33 are housed within the power supply housing 31, and the battery 32 is electrically connected to the electronic control board 33. The power supply housing 31 can be detachably connected to the housing assembly 1 for easy assembly. When the power supply housing 31 is assembled with the housing assembly 1, the battery 32 can be electrically connected to the atomizing core assembly 2. The electronic control board 33 has corresponding control circuitry for controlling the power supply status of the battery 32, so as to supply power to the atomizing core assembly 2 as needed, thereby controlling the heating process.

[0061] Furthermore, such as Figure 7 and Figure 13In the example, the atomizing core assembly 2 includes a first liquid-absorbing element 21 and a heating element 22. The first liquid-absorbing element 21 has a cylindrical structure, and its bottom extends into the liquid guiding channel 114. The heating element 22 is fixed inside the first liquid-absorbing element 21. The first liquid-absorbing element 21 can adsorb the aerosol matrix and distribute the aerosol matrix evenly on the surface of the heating element 22 to increase the heating area of ​​the aerosol matrix, so that the aerosol matrix can be fully heated and atomized. The lead structure of the heating element 22 extends into the bottom shell 111 of the base and is connected to the corresponding conductive element 1112. The conductive element 1112 is connected to the corresponding electrode on the battery 32, so that the battery 32 and the heating element 22 form an electrical connection.

[0062] like Figure 13 In the example shown, the side wall of the power supply housing 31 can extend upwards to allow the housing base 11 of the housing assembly 1 to extend into the power supply housing 31 for assembly. The housing base 11 and the power supply assembly 3 can be secured by snap-fit ​​or other means, or by magnetic attraction. Figure 13 As shown, a first magnetic attractor 1113 is provided at the bottom of the housing base 11, and a second magnetic attractor 512 is provided at a corresponding position on the top of the power supply housing 31. In a first direction, the magnetic poles of the first magnetic attractor 1113 and the second magnetic attractor 512 are in the same direction, so that the magnetic poles of the contact surfaces of the first magnetic attractor 1113 and the second magnetic attractor 512 are opposite, thereby forming an effect of opposite poles attracting each other and achieving magnetic fixation. In practical applications, the number and installation position of the first magnetic attractor 1113 and the second magnetic attractor 512 can be set according to specific usage needs and structural design.

[0063] An embodiment of the second aspect of this application provides an aerosol generating device 500, such as... Figure 3 and Figure 4 As shown, the aerosol generating device 500 includes the aerosol generating apparatus 100 in any of the embodiments of the first aspect described above and at least one liquid storage tank 510. The liquid storage tank 510 is used to store the aerosol matrix. The shape and size of the liquid storage tank 510 are adapted to the assembly part 1125 and the assembly space 1127 of the aerosol generating apparatus 100. In use, the liquid storage tank 510 can be installed into the assembly space 1127 of the housing assembly 1 and detachably connected to the assembly part 1125, so that the liquid storage tank 510 is connected to the liquid guiding channel 114 through the liquid inlet interface 1126. The aerosol matrix in the liquid storage tank 510 can flow into the liquid guiding channel 114 and then into the atomizing chamber 1124 for heating of the atomizing core assembly 2, thereby replenishing the aerosol matrix into the atomizing chamber 1124.

[0064] Furthermore, such as Figure 4In the example, the bottom of the liquid storage tank 510 can be provided with a corresponding liquid supply interface 511, so that when installed into the assembly space 1127, the liquid supply interface 511 can be connected to the liquid inlet interface 1126 to allow the aerosol matrix to flow normally into the liquid guiding channel 114 and prevent leakage. Preferably, the liquid supply interface 511 of the liquid storage tank 510 can be provided with a corresponding sealing membrane structure. In the initial state, the sealing membrane structure closes the liquid supply interface 511, for example... Figure 3 The state shown in the figure; when the liquid storage tank 510 is installed into the assembly space 1127 of the assembly part 1125, the liquid supply port 511 mates with the liquid inlet port 1126 and the sealing membrane structure is damaged, for example. Figure 4 As shown in the diagram, the liquid inlet port 1126 can be inserted into the liquid supply port 511, while simultaneously piercing the sealing membrane structure, which helps prevent leakage during assembly.

[0065] The following describes a specific example of the aerosol generating apparatus 500 of this application with reference to the accompanying drawings.

[0066] like Figures 1 to 13 In the example, the aerosol generating device 500 includes the aforementioned aerosol generating apparatus 100 and two liquid storage chambers 510, wherein the aerosol generating apparatus 100 includes a housing assembly 1, an atomizing core assembly 2, and a power supply assembly 3. The liquid storage chambers 510 can store aerosol matrix for replenishing the aerosol matrix into the atomizing chamber 1124.

[0067] The housing assembly 1 includes a housing base 11 and an upper housing 12 connected to each other in a first direction. The housing base 11 adopts a structure similar to an inverted T-shape, that is, an atomizing chamber 1124 extending in the first direction is provided at the top center of the housing base 11. The atomizing core assembly 2 is disposed in the atomizing chamber 1124 for heating the aerosol matrix in the atomizing chamber 1124. In the second direction, an assembly part 1125 protruding from the atomizing chamber 1124 is formed on each side of the atomizing chamber 1124. The upper housing 12 is connected to the top of the atomizing chamber 1124. The top of the upper housing 12 has a through-mouth 121 extending in a first direction, and the through-mouth 121 is connected to the atomizing core assembly 2. A second seal 125 is provided at the connection between the upper housing 12 and the atomizing chamber 1124. In the third direction, the upper housing 12 has a side shell portion 122 extending in the first direction on each side of the through-mouth 121. The bottom of the side shell portion 122 is through and extends to the housing base 11. The side shell portion 122 has an air inlet 124 on the side wall away from the through-mouth 121 in the third direction. The air inlet 124 is located near the top wall.

[0068] Correspondingly, the two mounting portions 1125 of the housing base 11 form mounting spaces 1127 facing the nozzle 121 in the first direction. The shape and size of the liquid storage tank 510 are adapted to the mounting portions 1125 and the mounting spaces 1127, and it can be installed in the mounting spaces 1127. A liquid guiding channel 114 communicating with the atomizing chamber 1124 is formed inside the housing base 11. The liquid guiding channel 114 has a liquid inlet 1126 extending to the mounting portion 1125. Correspondingly, the bottom of the liquid storage tank 510 has a liquid supply port 511 at the position for docking with the mounting portion 1125. When the liquid storage tank 510 is installed in the mounting space 1127 and detachably connected to the mounting portion 1125, the liquid supply port 511 is connected to the liquid inlet 1126 so that the aerosol matrix in the liquid storage tank 510 can enter the liquid guiding channel 114. The housing base 11 is formed by the mating of a base bottom shell 111 and a base top cover 112. A first air guide hole 1121 is provided on the base top cover 112 at a position corresponding to the side shell portion 122. The first air guide hole 1121 communicates with the air inlet channel 123 and is a strip-shaped hole extending along a second direction. A first sealing member 113 inside the housing base 11 divides the internal space of the housing base 11 into upper and lower layers. A liquid guiding channel 114 is located in the upper layer, and an air guiding cavity 115 is formed in the lower layer. A second air guide hole 115 is provided on the first sealing member 113. The second air guide hole 1131 is located on both sides of the liquid guiding channel 114 in the second direction, and both are strip-shaped holes extending in the third direction, so as to connect the first air guide hole 1121 and the air guiding chamber 115 through the second air guide hole 1131; the atomizing chamber 1124 and the atomizing core assembly 2 are located at the center of the base top cover 112, and the third air guide hole 1132 is correspondingly arranged with the atomizing core assembly 2 and is sealed with the bottom of the atomizing core assembly 2 so that the air guiding chamber 115 is connected to the inside of the atomizing core assembly 2. The bottom of the first liquid-absorbing element 21 of the atomizing core assembly 2 extends into the liquid guiding channel 114. The first liquid-absorbing element 21 has an inner channel that runs through the first direction. The heating element 22 is located in the inner channel of the first liquid-absorbing element 21. The first liquid-absorbing element 21 adsorbs the aerosol matrix and distributes the aerosol matrix evenly on the surface of the heating element 22 so as to heat the aerosol matrix through the heating element 22. The pin structure of the heating element 22 extends to the bottom shell 111 of the base and is connected to the corresponding conductive element 1112.

[0069] Specifically, in the third direction, the thickness of the shell assembly 1 is the same as the thickness of the two liquid storage chambers 510, so that the outer side wall of the side shell 122 is flush with the outer side wall of the two liquid storage chambers 510. The atomizing chamber 1124 has a capacity of 2ml, and the two liquid storage chambers 510 each have a capacity of 10ml, forming a liquid storage capacity combination of 2ml + 10ml + 10ml.

[0070] The power supply component 3 is located below the housing base 11. The power supply housing 31 of the power supply component 3 can be plugged into the housing base 11 along a first direction. The bottom of the housing base 11 has two first magnetic members 1113, and the corresponding positions on the power supply component 3 have two second magnetic members 512. The corresponding first magnetic members 1113 and second magnetic members 512 attract each other, thus connecting and fixing the power supply component 3 to the housing base 11. Simultaneously, the conductive member 1112 at the bottom of the housing base 11 is electrically connected to the battery 32 of the power supply component 3, and the power supply status of the battery 32 can be controlled by the electronic control board 33.

[0071] In practical applications, corresponding liquid-absorbing components can be installed in the air-guiding chamber 115 as needed, and corresponding liquid-absorbing components can also be installed at the position of the second liquid-absorbing component facing the outer end of the nozzle 121 to absorb condensate. In addition, corresponding sensing air channels can be installed on the base shell 111, and corresponding sensors can be installed in the power supply assembly 3. The sensors are electrically connected to the electronic control board 33. During use, a negative pressure is generated in the air-guiding chamber 115, causing airflow to occur in the space where the sensor is located under the action of negative pressure. The sensor generates a corresponding sensing signal, and the control circuit of the electronic control board 33 controls the battery 32 to supply power to the heating element 22 of the atomizing core assembly 2 according to the sensing signal.

[0072] In this embodiment, the aerosol generating device employs an inverted T-shaped housing assembly, capable of simultaneously assembling two liquid storage chambers. This fully utilizes the internal three-dimensional space of the housing assembly to achieve a more rational arrangement of the liquid storage chambers and air intake channels. The air intake channels and liquid storage chambers are positioned perpendicular to each other relative to the atomizing chamber, preventing mutual interference. Within a limited space, this design achieves both an expansion of the liquid storage chambers in the second direction (with 10ml capacity chambers on both sides of the atomizing chamber) and sufficient space in the air intake channels to meet normal operating requirements. Furthermore, when external air enters the air intake channels, it absorbs heat from the side walls of the atomizing chamber, raising the airflow temperature and preventing cold air from directly entering the atomizing core assembly and affecting normal atomization. Simultaneously, the airflow path requires multiple changes of direction, which also helps prevent condensate leakage through the air intake channels.

[0073] In addition, since the shell assembly and the liquid storage chamber have the same dimensions in the third direction, the empty space on both sides of the atomizing chamber in the third direction of the shell assembly naturally forms a sandwich structure. In this embodiment, the sandwich structure is used as an air intake channel. There is no need to add an additional air passage structure. Only a simple drilling operation is required to form the air intake channel. The interior of the shell base only needs to use the existing structure to process the corresponding air guide holes to realize the connection between the air intake channel and the atomizing core assembly. This is beneficial to simplify the structure and processing operation, and can improve production efficiency and reduce manufacturing costs to a certain extent.

[0074] Furthermore, the aerosol generating device 500 in this embodiment has all the beneficial effects of the aerosol generating device 100 in any of the above embodiments, and will not be repeated here.

[0075] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
