[0033] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] After the aerosol generating device heats the aerosol matrix, it is difficult to remove it, which makes it inconvenient to replace the aerosol matrix. After long-term use, condensed liquid will accumulate in the airflow channel of the aerosol generating device, and the accumulated liquid is also difficult to clean.

[0037] See also Figures 1 to 7 The embodiment of the present application provides an aerosol generating device, including a shell 1, a heating component 5, a container 2 and other functional components that exist as needed, which are described in detail below.

[0038] The housing 1 in this embodiment is provided with an installation cavity 103, and the heating assembly 5 is provided in the housing 1, and the heating assembly 5 includes a heating element 501. The heating assembly 5 in this embodiment generates aerosol by heating the heating element 501 to heat the aerosol matrix 7. The heating assembly 5 may include a bracket 502, and the bracket 502 is connected to the housing 1 to fix the heating assembly 5 in the housing 1. In this embodiment, other components of the heating assembly 5 may be fixed by the bracket 502. In this embodiment, the material of the housing 1 is not specifically limited, and it can be selected according to needs. For example, in order to isolate the heat generated by the heating assembly 5, the housing 1 may be made of a material with a low thermal conductivity.

[0039] The receiving component 2 in this embodiment is detachably connected to the shell 1, and the receiving component 2 includes a main body 3 and an exposed component 4 fixedly connected to the main body 3; the main body 3 is inserted into the installation cavity 103, and the main body 3 is provided with a receiving cavity 301 for inserting the aerosol matrix 7, and the heating element 501 is inserted into the receiving cavity 301 through the insertion hole 302 provided at the bottom of the main body 3, and is used to heat the aerosol matrix 7. The main body 3 is provided with an air inlet 303 connected to the receiving cavity 301; at least a part of the exposed component 4 protrudes from the outer surface of the shell 1 from the installation cavity 103.

[0040] It is understandable that the container 2 is detachably connected to the shell 1, that is, the container 2 can be connected to the shell 1 so that the container 2 and the shell 1 are fixed to each other, and the container 2 can also be removed from the shell 1 so that the container 2 and the shell 1 are separated from each other. After the container 2 is removed, it is easier to clean the aerosol matrix 7 and the accumulated liquid in the accommodating chamber 301, which provides convenience for the user. The aerosol matrix 7 inserted in the accommodating chamber 301 in this embodiment can be but is not limited to a cigarette. The heating element 501 in this embodiment is inserted into the accommodating chamber 301, such as Figure 7 As shown, when the aerosol matrix 7 is inserted into the accommodating cavity 301, the heating element 501 will be inserted into the aerosol matrix 7, and the heating element 501 can heat the aerosol matrix 7 to generate aerosol. The air inlet 303 provided on the main body 3 realizes the circulation of gas, so that the air inlet 303 and the accommodating cavity 301 form an air flow channel of the aerosol generating device. This embodiment does not limit the specific setting position and number of the air inlet 303, and the gas circulation can be realized for the user to inhale the aerosol. For example, two, three or four air inlet holes 303 can be set at the bottom of the accommodating cavity 301, and in order to prevent the occurrence of airflow dead angles, the air inlet holes 303 can be evenly distributed around the plug 302. In some application scenarios, a larger hole can also be directly set at the bottom of the accommodating cavity 301, and the heating element 501 is inserted into the accommodating cavity 301 through the hole. At the same time, the hole also serves as the air inlet 303, and the gas can flow into the accommodating cavity 301 through the remaining space in the hole except the heating element 501. In this embodiment, the exposed part 4 protrudes from the outer surface of the shell 1, which facilitates the disassembly of the accommodating part 2. The exposed part 4 can partially extend from the cavity opening of the installation cavity 103 and protrude from the outer surface of the shell 1, or it can be completely located outside the cavity opening of the installation cavity 103 and protrude from the outer surface of the shell 1.

[0041] The container 2 in this embodiment includes a main body 3 and an exposed part 4, and the main body 3 is fixedly connected to the exposed part 4, which facilitates the arrangement of the container 2. For example, for the sake of aesthetics, the exposed part 4 can be made of a material with a smoother surface or a transparent material, while the main body 3 can be made of an ordinary material, thereby meeting the aesthetic requirements and reducing the production cost; or the exposed part 4 can be made of a material with a relatively low thermal conductivity, while the main body 3 can be made of a material with a relatively high thermal conductivity, thereby making the exposed part 4 exposed on the outer surface of the shell 1 less likely to heat up and more conducive to the use of the device. In some application scenarios, the main body 3 and the exposed part 4 can also be an integrated structure.

[0042] In one embodiment, the container 2 includes a limiting portion 202 and a first clamping portion 201. The limiting portion 202 cooperates with the housing 1 to limit the axial position of the container 2. The first clamping portion 201 cooperates with the housing 1 to provide an axial preload force to the container 2, so that the container 2 is detachably connected to the housing 1. The limiting portion 202 and the first clamping portion 201 provided on the container 2 facilitate the installation and disassembly of the container 2. It can be understood that the axial limit formed by the limiting portion 202 and the housing 1 can prevent the container 2 from moving on one side in the axial direction, and the axial preload force provided by the first clamping portion 201 and the housing 1 can limit the movement of the container 2 on the other side in the axial direction. When disassembling, the container 2 can be taken out when the applied force is greater than the axial preload force.

[0043] In one embodiment, the main body 3 is provided with a first clamping portion 201, and the inner wall of the installation cavity 103 is provided with a second clamping portion 105. Of the first clamping portion 201 and the second clamping portion 105, one is a clamping protrusion and the other is an elastic arm. The elastic arm abuts against the clamping protrusion to provide an axial preload force to the accommodating member 2. The elastic arm can be elastically deformed under the action of an external force, and the elastic force stored when the elastic arm abuts against the clamping protrusion forms an axial preload force. In this embodiment, Figure 4 As shown, the first clamping portion 201 can be a clamping protrusion, and the second clamping portion 105 can be an elastic arm. When assembling, the elastic arm on the inner wall of the installation cavity 103 presses against the clamping protrusion on the accommodating member 2 to form axial preload; or the first clamping portion 201 can also be an elastic arm, and the second clamping portion 105 can be a clamping protrusion. When assembling, the elastic arm on the accommodating member 2 presses against the clamping protrusion on the inner wall of the installation cavity 103 to form axial preload. In order to make the cooperation between the clamping protrusion and the elastic arm better, as shown in FIG. Figure 4As shown, the free end of the elastic arm that cooperates with the clamping protrusion can be bent. During assembly, the clamping protrusion cooperates with the bent portion of the free end, which is similar to the structure in which the free end hooks the clamping protrusion, thereby making the axial preload more stable. At the same time, in order to make disassembly more convenient, an inclined surface or an arc surface can be provided on the clamping protrusion for disengagement guidance. For example, the outer surface of the clamping protrusion can be directly made into an arc surface. In some application scenarios, the first clamping portion 201 can also cooperate with other structures provided on the housing 1 to provide an axial preload force to the accommodating member 2.

[0044] In one embodiment, Figure 4 , Figure 2 As shown, the exposed part 4 is provided with a limiting step, which is a limiting portion 202, and the limiting step abuts against the outer edge of the cavity opening of the installation cavity 103 to form an axial limit for the accommodating part 2. The limiting step is provided on the exposed part 4, which not only realizes the axial limit of the accommodating part 2, but also forms the positioning of the exposed part 4, so that at least part of the exposed part 4 protrudes from the outer surface of the housing 1. The above is only an example of the axial limit formed by the limiting portion 202 and the housing 1. The limiting portion 202 can also be other shapes, and the limiting portion 202 can also be provided at other parts of the accommodating part 2.

[0045] In one embodiment, the exposed member 4 is disposed at one end of the main member 3 near the opening of the accommodating cavity 301, the exposed member 4 is provided with a third clamping portion 401, the main member 3 is provided with a fourth clamping portion 304, and the third clamping portion 401 cooperates with the fourth clamping portion 304 to fix the exposed member 4 to the main member 3. The exposed member 4 and the main member 3 are fixed by clamping, and the assembly is faster. In some application scenarios, the exposed member 4 and the main member 3 can also be connected and fixed by other means, such as bonding, threaded connection, interference fit, etc.

[0046] In one embodiment, Figure 1 , Figure 4As shown, the exposed part 4 is provided with a cavity 402, and one end of the main part 3 close to the cavity opening of the accommodating cavity 301 is inserted into the cavity 402, and the cavity 402 is provided with an opening for inserting the aerosol matrix 7 into the accommodating cavity 301; the inner wall of the cavity 402 is provided with a third clamping portion 401, and the outer peripheral side wall of the end of the main part 3 inserted into the cavity 402 is provided with a fourth clamping portion 304. The main part 3 is inserted into the cavity 402, so that the exposed part 4 covers the main part 3 better, which is more conducive to the setting of aesthetics or heat insulation. The third clamping portion 401 is set on the inner wall of the cavity 402, and the fourth clamping portion 304 is set on the outer peripheral side wall of the main part 3, so that when the main part 3 is inserted into the cavity 402, the clamping fit between the third clamping portion 401 and the fourth clamping portion 304 can be formed. The present embodiment does not limit the specific shapes of the third clamping portion 401 and the fourth clamping portion 304, and any clamping connection between the two can be formed. For example, one of the third clamping portion 401 and the fourth clamping portion 304 can be a groove and the other can be a protrusion, and the protrusion cooperates in the groove to form a clamping fixation.

[0047] In one embodiment, Figure 1 The housing 1 includes a body 101 and a connection seat 102. The body 101 is provided with a mounting opening 106. The connection seat 102 is provided at the mounting opening 106 and is connected and fixed to the body 101. A mounting cavity 103 is provided in the connection seat 102. The receiving member 2 is detachably connected to the connection seat 102. The housing 1 includes the body 101 and the connection seat 102, which can reduce the complexity of manufacturing the housing 1. During manufacturing, the body 101 and the connection seat 102 are separately manufactured, and then the connection seat 102 is fixed to the mounting opening 106 of the body 101. In some application scenarios, the body 101 and the connection seat 102 can also be an integrated structure.

[0048] In one embodiment, Figure 1 , Figure 3 As shown, the outer peripheral side wall of the connection seat 102 is provided with a limiting protrusion 104, and the connection seat 102 is inserted into the body 101 from the installation opening 106. The limiting protrusion 104 abuts against the inner edge of the installation opening 106 to limit the connection seat 102 from coming out of the installation opening 106. The limiting protrusion 104 limits the connection seat 102 from coming out, which not only simplifies the connection between the connection seat 102 and the body 101, but also makes the connection between the connection seat 102 and the body 101 more stable. In order to make the connection seat 102 more smoothly inserted into the body 101, a guiding inclined surface can be provided on the limiting protrusion 104. In some application scenarios, the connection seat 102 can also be fixed at the installation opening 106 by other means.

[0049] In one embodiment, Figure 6As shown, the heating component 5 includes a bracket 502, and both ends of the mounting cavity 103 are open, wherein the opening at one end is for the main body 3 to be inserted into the mounting cavity 103, and the opening at the other end is for the bracket 502 to be inserted into the mounting cavity 103 and connected to the heating component 5. The mounting cavity 103 can not only mount the accommodating component 2, but also form a connection between the mounting cavity 103 and the heating component 5 after one end of the bracket 502 is inserted into the mounting cavity 103 from the corresponding opening, which is more conducive to stably keeping the heating element 501 in the accommodating cavity 301. In some application scenarios, the bracket 502 can also be fixed by other parts set on the housing 1, so that the heating element 501 can be stably kept in the accommodating cavity 301.

[0050] In the aerosol generating device provided in the above embodiment, the container 2 is detachably connected to the housing 1, such as Figure 2 As shown, when the accommodating cavity 301 needs to be cleaned, the accommodating member 2 can be removed from the housing 1. After removal, it is easier to clean the aerosol matrix 7 and the accumulated liquid in the accommodating cavity 301, which provides convenience for the user and improves the user experience. In addition, the accommodating member 2 includes a main body 3 and an exposed member 4, and the main body 3 is fixedly connected to the exposed member 4, thereby facilitating the arrangement of the accommodating member 2.

The specific structure of the aerosol generating device in this embodiment is the same as that in the above embodiment, and will not be repeated here. This embodiment does not limit the specific layout of the power supply 6, the circuit board, and the heating component 5 in the shell 1. For example, the circuit board can be arranged at the bottom of the shell 1, the heating component 5 is arranged on one side of the shell 1, the power supply 6 is located on the other side of the shell 1 next to the heating component 5, and the accommodating part 2 is arranged in the installation cavity 103 above the heating component 5, and is detachably connected to the shell 1.
