[0003] This application relates to the field of atomization technology, specifically to an aerosol generating device. Background Technology

[0004] An aerosol generator is an electronic delivery system that uses control circuits and atomizing elements to control its operating status and vapor output for user use.

[0005] In related technologies, aerosol generating devices include a power supply component and an atomizer. The power supply component has a receiving cavity, and the atomizer is detachably inserted into the receiving cavity to achieve electrical and physical connection with the power supply component. Because the receiving cavity is quite deep, the area inside the receiving cavity cannot be visually observed after the atomizer is inserted, making it inconvenient to perform electrical and physical connection operations between the atomizer and the power supply component. Therefore, replacing the atomizer is inconvenient. Summary of the Invention

[0077] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0078] This application provides an aerosol generating device, as shown in Figure 1 or Figure 7. The aerosol generating device includes an atomizer 1 and a power supply assembly 2.

[0079] It should be noted that the specific type of aerosol generating device in the embodiments of this application is not limited. For example, the aerosol generating device can be a medical nebulizer, an air humidifier, or a nebulizer such as an electronic cigarette.

[0080] The power supply component 2 is mainly used to supply power to the atomizer 1 and can also be used to control the opening and closing of the entire aerosol generation device. The atomizer 1 is mainly used to contain the aerosol generation matrix and heat and atomize the aerosol generation matrix after being powered on to generate aerosols. The aerosol generation matrix includes, but is not limited to, materials used for medical, health, and beauty purposes.

[0081] Please refer to Figures 1 and 2, or Figures 7 and 8, Figures 13 to 17. The two ends of the atomizer 1 along the first direction are the suction end 1a and the bottom end 1b of the shell, respectively.

[0082] For example, the first direction is the direction shown by L in Figures 1, 7, 13, 18 and 22.

[0083] The inhalation end 1a is located at one end of the atomizer 1 and is the part that directly contacts the user. The user inhales the aerosol through this end. The bottom end 1b of the shell is the end opposite to the inhalation end 1a. For example, the atomizer 1 includes a mouthpiece, and the outlet end of the mouthpiece is the inhalation end 1a. The user can inhale the aerosol by holding the mouthpiece in their mouth. It is understood that when determining the first direction, the direction of the suction force applied by the user inhaling the aerosol can be considered as one side of the first direction, and the direction opposite to the direction of the suction force is considered as the other side of the first direction.

[0084] Since users typically draw aerosols from bottom to top, the first direction can also be understood as the height direction of the aerosol generating device. Therefore, in the specific embodiments below, for ease of explaining the technical effects of the corresponding embodiments, the first direction will be interpreted as the height direction. Specifically, the "height" mentioned in the specific embodiments below should be understood with reference to the height direction.

[0085] Please refer to Figure 2 or Figure 8. The power supply assembly 2 includes a power supply section 21 and a fixing unit 22.

[0086] The power supply unit 21 is a component of the power supply assembly 2 used to supply power to the atomizer 1 and to control the opening and closing of the entire aerosol generating device.

[0087] From the perspective of looking from the suction end 1a towards the bottom end 1b of the housing, the visible area of ​​the outer surface of the power supply unit 21 is the first area surface 21a. Here, it refers to the portion of the power supply unit 21 that can be observed from the atomizer 1 along a first direction from the suction end 1a towards the bottom end 1b of the housing, where the observer is viewing the power supply assembly 2 alone. It should be noted that this specific perspective is only to illustrate the observation direction for observing the power supply assembly 2 alone to obtain the position of the first area surface 21a, and does not refer to the area that can be observed on the power supply assembly 2 along this direction after the atomizer 1 and the power supply assembly 2 are fully engaged.

[0088] It should be noted that when determining the first region surface 21a, the first direction needs to be determined first. For example, when the aerosol generating device is in a stationary state, the first direction can be determined. At this time, while keeping the position and angle of the power supply unit 21 unchanged, remove the other components of the aerosol generating device except for the power supply unit 21, and then observe the power supply unit 21 from this perspective, thereby determining the first region surface 21a.

[0089] Please refer to Figure 17. The first region surface 21a includes a first part surface 21a1. The outer edge of the first part surface 21a1 and the outer edge of the first region surface 21a have at least a partial overlap.

[0090] Referring to Figures 1, 2, 21, and 26, the outer edge of the first partial surface 21a1 can constitute the entire outer edge of the first region surface 21a. In this embodiment, the first partial surface 21a1 constitutes the entire first region surface 21a.

[0091] Referring to Figures 7, 8, and 17, the outer edge of the first partial surface 21a1 may also constitute a portion of the outer edge of the first region surface 21a. In this embodiment, the first partial surface 21a1 constitutes a portion of the first region surface 21a, and other regions of the first region surface 21a, excluding the first partial surface 21a1, do not surround the first partial surface 21a1 for an entire circumference along its outer edge; that is, a portion of the first partial surface 21a1 extends to the outer edge of the first region surface 21a.

[0092] Please refer to Figures 1 and 2, or Figures 7 and 8, where the end face of the bottom end 1b of the shell is positioned opposite to the first partial surface 21a1 along a first direction.

[0093] Relative to the side where the suction end 1a is located, the first partial surface 21a1 has no recessed area 21b, or the first partial surface 21a1 has a recessed area 21b that is recessed in the first direction away from the atomizer 1, and a part of the atomizer 1 extends into the recessed area 21b. The atomizer 1 includes a liquid storage chamber 12a, an atomizing core 11, and an atomizing chamber 13a.

[0094] The recessed area 21b has a height such that, when the atomizer 1 is installed in the power assembly 2, it does not exceed the lowest point of at least one of the atomizing coil 11, the atomizing chamber 13a, or the liquid reservoir 12a of the atomizer 1. In other words, when the atomizer 1 is installed in the power assembly 2, the atomizing coil 11, the liquid reservoir 12a, and the atomizing chamber 13a are at least partially located outside the recessed area 21b.

[0095] With the first direction as the height direction, the area on the first partial surface 21a1 that has the capacity to hold liquid is the recessed area 21b. The recessed depth of the recessed area 21b refers to the maximum depth to which the recessed area 21b can hold liquid.

[0096] In some embodiments, the first partial surface 21a1 has no recessed area 21b. That is, the first partial surface 21a1 is generally planar or has at least a partially protruding area relative to the suction end 1a. In this way, the height of the portion constituting the outer edge of the first area surface 21a in the outer edge of the first partial surface 21a1 is generally higher than the height of the middle area of ​​the first partial surface 21a1. Thus, when the atomizer 1 is installed and removed from the power assembly 2 in more directions, the first partial surface 21a1 has a relatively small impact on the bottom end 1b of the shell, thereby facilitating the replacement of the atomizer 1.

[0097] It is understandable that when there is a raised area on the first part surface 21a1, it is also considered that there is no recessed area 21b on the first part surface 21a1.

[0098] In other embodiments, a portion of the atomizer 1 extends into the recessed area 21b. The atomizer 1 includes an atomizing core 11, a liquid storage chamber 12a for storing the aerosol generation matrix, and an atomization chamber 13a (the space where atomization occurs). The liquid storage chamber 12a and the atomizing core 11 are in liquid communication. At least a portion of the liquid storage chamber 12a, the atomization chamber 13a, and the atomizing core 11 are located outside the recessed area 21b. Thus, the depth of the recessed area 21b is relatively shallow, which reduces the limitation on the installation direction of the atomizer 1. Furthermore, the recessed area 21b does not substantially obstruct the atomizer 1, thereby facilitating the replacement of the atomizer 1.

[0099] In addition, in some embodiments, the atomizer 1 uses a housing assembly 12 made of transparent or semi-transparent material. The aerosol generating matrix located in the liquid storage chamber 12a can be observed through the housing assembly 12, making it easy for the user to confirm the remaining amount of the aerosol generating matrix. At the same time, the atomizing core 11 can also be observed through the housing assembly 12, so that the atomization process of the aerosol generating matrix can be better observed, making it easy for the user to confirm whether the aerosol generating matrix is ​​being atomized normally.

[0100] It should be noted that there are no restrictions on the specific materials used for transparent or translucent materials. For example, it can be glass, transparent plastic, etc.

[0101] In this embodiment of the application, when the atomizer 1 is connected to the power supply assembly 2, at least a portion of the atomizing chamber 13a, the liquid storage tank 12a, and the atomizing core 11 are located outside the recessed area 21b. That is, the portion of the atomizer 1 inserted into the power supply assembly 2 does not include at least one of the atomizing chamber 13a, the liquid storage tank 12a, and the atomizing core 11, and at least a portion of the atomizing chamber 13a, the liquid storage tank 12a, and the atomizing core 11 are not located within the recessed area 21b.

[0102] In some embodiments, the power supply assembly 2 is placed on a support surface, which can be a horizontal surface, an inclined surface, a vertical surface, etc. For example, the support surface is a horizontal surface, and when the atomizer 1 is connected to the power supply assembly 2, the atomizer 1 is located above the power supply assembly 2, and the highest point of the recessed area 21b is not higher than the lowest point of at least one of the atomizing chamber 13a, the liquid storage tank 12a, and the atomizing core 11.

[0103] It should be noted that there are no restrictions on the height relationship between the lowest points of the atomizing chamber 13a, the liquid storage chamber 12a, and the atomizing core 11.

[0104] In one example, the lowest point of the liquid storage chamber 12a is not higher than the lowest point of the atomizing chamber 13a and the atomizing core 11; in another example, the lowest point of the atomizing chamber 13a is not higher than the lowest point of the liquid storage chamber 12a and the atomizing core 11; in yet another example, the lowest point of the atomizing core 11 is not higher than the lowest point of the liquid storage chamber 12a and the atomizing chamber 13a.

[0105] Here, the lowest point refers to the point where the vertical distance between the structure or space and the bearing surface is the smallest, and the highest point refers to the point where the vertical distance between the structure or space and the bearing surface is the largest. For example, the lowest point of the atomizing chamber 13a, the liquid storage chamber 12a and the atomizing core 11 refers to the point among the three that is closest to the bearing surface in terms of vertical distance, and the highest point of the recessed area 21b refers to the point in the recessed area 21b that is farthest from the bearing surface in terms of vertical distance.

[0106] Atomizer 1 and power supply unit 2 are electrically connected. Power supply unit 2 is able to supply electrical energy to atomizer 1.

[0107] It should be noted that the method of electrical connection between the atomizer 1 and the power supply assembly 2 is not limited. For example, the power supply assembly 2 is provided with a power supply area, and the atomizer 1 is provided with a power receiving area. A conductive path is formed between the power supply area and the power receiving area, thereby realizing the electrical connection between the power supply assembly 2 and the atomizer 1.

[0108] The connection between the power supply area and the power receiving area can be wireless or physical, such as using pins, springs, contacts, magnets, or grooves.

[0109] In some embodiments, when the power supply area and the power receiving area are electrically connected using a solid structure, this solid structure can also simultaneously achieve a physical connection between the atomizer 1 and the power supply component 2. Thus, the atomizer 1 and the power supply component 2 can achieve both electrical and physical connection using a single solid structure, thereby simplifying the assembly steps of the atomizer 1 and improving its assembly efficiency.

[0110] In some embodiments, the atomizer 1 and the power supply assembly 2 are physically connected via a solid structure, which may not require an electrical connection between them. Specifically, the atomizer 1 and the power supply assembly 2 can be connected wirelessly. This way, only one set of physical structures needs to be assembled during the assembly of the atomizer 1 and the power supply assembly 2, simplifying the assembly process and improving assembly efficiency. Alternatively, the atomizer 1 and the power supply assembly 2 can be electrically connected using another set of physical structures. This allows for separate electrical and physical connections between the atomizer 1 and the power supply assembly 2, without interference between the two sets of structures. This improves the stability and reliability of both the electrical and physical connections between the atomizer 1 and the power supply assembly 2.

[0111] The fixing unit 22 is provided on the power supply section 21 and is spaced apart from the first partial surface 21a1 along the first direction. Here, as shown in Figures 11 and 12, the fixing unit 22 may be directly provided on the power supply section 21; as shown in Figures 5 and 6, the fixing unit 22 may also be indirectly provided on the power supply section 21 through other structures.

[0112] It is understandable that, in the height direction, the height of the fixed unit 22 is higher than the height of the first part surface 21a1.

[0113] The fixing unit 22 surrounds the atomizer 1. Here, the direction of the surround is the circumference of the atomizer 1. It should be noted that the fixing unit 22 does not need to completely or completely surround the atomizer 1 in the circumference. That is, in some embodiments, the fixing unit 22 partially surrounds the atomizer 1 in the circumference, as long as it can achieve auxiliary fixation of the atomizer 1.

[0114] It should be noted that, in this embodiment, the circumferential direction of the atomizer 1 refers to a clockwise or counterclockwise direction of rotation about the first direction as an axis. It should also be pointed out that the shape of the atomizer 1 is not limited thereto; the cross-section of the atomizer 1 perpendicular to the first direction is not limited to a circle, but can also be any two-dimensional shape such as an ellipse, triangle, quadrilateral, or pentagon. The fixing unit 22 surrounds the atomizer 1 circumferentially, meaning that at least one side (including part or all of at least one side) or at least a portion of the side of the atomizer 1 is surrounded by the fixing unit 2 circumferentially.

[0115] Thus, with the atomizer 1 positioned behind the power supply assembly 2 (see Figure 1 or Figure 7), the fixing unit 22 can at least limit the displacement of the atomizer 1 in a plane perpendicular to the first direction, thereby improving the reliability and stability of the electrical and physical connection between the atomizer 1 and the power supply assembly 2.

[0116] It is understood that, as shown in Figure 1 or Figure 7, in this embodiment of the application, most of the peripheral surface of the atomizer 1 is exposed to the external environment in the area between the fixing unit 22 and the first partial surface 21a1, and this part of the peripheral surface also constitutes the outer surface of the aerosol generating device.

[0117] In addition, the atomizer 1 uses a transparent or semi-transparent housing assembly 12. The aerosol generating matrix located in the liquid storage chamber 12a can be observed through the housing assembly 12, which makes it easy for the user to confirm the remaining amount of the aerosol generating matrix. At the same time, the atomizing core 11 can also be observed through the housing assembly 12, so that the atomization process of the aerosol generating matrix can be better observed, which makes it easy for the user to confirm whether the aerosol generating matrix is ​​being atomized normally.

[0118] In related technologies, aerosol generating devices include a power supply component and an atomizer. The power supply component has a receiving cavity, and the atomizer is detachably inserted into the receiving cavity to achieve electrical and physical connection with the power supply component. Because the receiving cavity is quite deep, the area inside the cavity cannot be visually observed after the atomizer is inserted, making it inconvenient to perform electrical and physical connection operations between the atomizer and the power supply component. Therefore, replacing the atomizer is inconvenient. Furthermore, based on this structure, the atomizer is prone to scraping against the cavity wall of the power supply component during disassembly and assembly, potentially damaging the electrical connection structure of the atomizer. It also makes cleaning or maintenance of the electrical connection structure of the power supply component difficult.

[0119] In the aerosol generating device of this application embodiment, when the atomizer 1 is installed on the power supply assembly 2, the bottom end 1b of the atomizer 1's shell is positioned opposite to the first partial surface 21a1 of the power supply section 21. Since the first partial surface 21a1 extends to the outer edge region of the top wall of the power supply section 21, and relative to the side where the suction end 1a is located, the first partial surface 21a1 is either configured without a recessed area 21b, or configured with a recessed area 21b, and the recessed area 21b has a height such that when the atomizer 1 is installed on the power supply assembly 2, it does not exceed the lowest point of at least one of the atomizing core 11, the atomizing chamber 13a, or the liquid storage tank 12a of the atomizer 1. In other words, when the atomizer 1 is installed on the power supply assembly 2, at least a portion of the atomizing core 11, the liquid storage tank 12a, and the atomizing chamber 13a are located outside the recessed area 21b. In this way, the first part 21a1 will not have a significant obstruction effect on the structure of the atomizer 1, thus facilitating the replacement of the atomizer 1. During the disassembly and assembly of the atomizer 1, the first part 21a1 is nearly flush with the bottom end 1b of the shell, which helps to reduce the probability of the atomizer 1 scraping against the power supply component 2 during disassembly and assembly, thereby improving the reliability of the electrical connection structure of the atomizer 1. The structure of the power supply 21 at the atomizer 1 mounting position is also an open structure, which facilitates the maintenance of the electrical connection structure of the power supply 21 and also makes it easy for the power supply component 2 to adapt to atomizers 1 of different sizes.

[0120] Furthermore, the power supply assembly 2 surrounds the atomizer 1 via a fixing unit 22. The atomizer 1 is located behind the power supply assembly 2. The fixing unit 22 can at least limit the displacement of the atomizer 1 in a plane perpendicular to the first direction, thereby improving the reliability and stability of the electrical and physical connection between the atomizer 1 and the power supply assembly 2.

[0121] The aerosol generating device of this application embodiment has strong visibility of the atomizer 1, which also facilitates cleaning and maintenance of the surface of the power supply component 2 used to cooperate with the atomizer 1. The assembly of the atomizer 1 and the power supply component 2 is relatively simple, which helps to reduce production costs and improve production efficiency. At the same time, the atomizer 1 has a large exposed area on the power supply component 2, which provides better heat dissipation.

[0122] It should be noted that there are no restrictions on the fit between the fixing unit 22 and the peripheral side of the atomizer 1.

[0123] In some embodiments, see Figures 3 and 4, or Figures 9 and 10, the fixing unit 22 abuts against the peripheral side of the atomizer 1.

[0124] Here, the wall surface of the fixing unit 22 on the side opposite to the peripheral side of the atomizer 1 can be in complete contact with the peripheral side of the atomizer 1, or only partially in contact with the peripheral side of the atomizer 1.

[0125] In this embodiment, in the area where the fixing unit 22 abuts against the peripheral side of the atomizer 1, an abutting force is generated between the fixing unit 22 and the atomizer 1. This helps to further improve the stability of the position of the atomizer 1 on the power supply assembly 2.

[0126] In some embodiments, there is a gap between the fixing unit 22 and the peripheral side of the atomizer 1.

[0127] It should be noted that the specific method of forming the gap between the fixing unit 22 and the peripheral surface of the atomizer 1 is not limited. For example, point contact can be formed between the fixing unit 22 and the atomizer 1, and the number of point contacts is also not limited. For example, in a specific embodiment, the cross-section obtained by cutting the atomizer 1 with a plane perpendicular to the first direction is polygonal, and the fixing unit 22 is an annular. In this way, on the plane perpendicular to the first direction, the points on the corners of the atomizer 1 make point contact with the inner wall of the annular fixing unit 22. Here, based on a specific corner of the atomizer 1, the corner and the annular fixing unit 22 approximately form line contact.

[0128] In this embodiment, by forming a gap between the fixing unit 22 and the peripheral side of the atomizer 1, the contact area between the atomizer 1 and the fixing unit 22 is reduced when the atomizer 1 is installed and removed from the power supply assembly 2 in the first direction. This reduces the friction between the two, making it easier to install and remove the atomizer 1. At the same time, it also helps to reduce the probability of scratch damage to the peripheral side of the atomizer 1.

[0129] Furthermore, at any position along the circumference of the atomizer 1, the fixing unit 22 and the atomizer 1 can be in no contact. Thus, even if the atomizer 1 is installed and removed from the power assembly 2 in the first direction, the peripheral side of the atomizer 1 and the fixing unit 22 can remain in contact without mutual friction, further facilitating the installation and removal of the atomizer 1 and reducing the likelihood of scratches and damage to the peripheral side of the atomizer 1. In some embodiments, referring to Figures 7 and 8, in the first direction, the distance between the fixing unit 22 and the suction end 1a is smaller than the distance between the fixing unit 22 and the bottom end 1b of the shell.

[0130] In this way, the fixing unit 22 helps to strengthen the stability of the atomizer 1's suction end 1a, while the bottom end 1b of the atomizer 1 facilitates the connection structure with the power supply unit 21. Thus, the atomizer 1 can be easily and stably mounted on the power supply unit 2 at both the suction end 1a and the bottom end 1b, thereby further improving the installation stability of the atomizer 1.

[0131] In some embodiments, please refer to Figures 2 and 5, the fixing unit 22 is provided with an annular opening 22a; or, please refer to Figures 8 and 11, the fixing unit 22 and the power supply unit 21 surround to form an annular opening 22a, and the atomizer 1 passes through the annular opening 22a.

[0132] A portion of the wall of the power supply assembly 2 extends around the circumference of the atomizer 1, thus forming an area called the annular opening 22a.

[0133] Please refer to Figures 2 and 5. In the embodiment where the fixing unit 22 has an annular opening 22a, the wall surrounding the annular opening 22a is entirely the structure of the fixing unit 22.

[0134] Please refer to Figures 8 and 11. In the embodiment where the fixing unit 22 and the power supply unit 21 surround to form an annular opening 22a, a part of the wall surrounding to form the annular opening 22a is the structure of the fixing unit 22, and the other part is the structure of the power supply unit 21.

[0135] It should be noted that the annular opening 22a can be formed by a continuous extending wall. In this case, the periphery of the annular opening 22a cannot be opened, and the atomizer 1 can only pass through the annular opening 22a along its axial direction. It can be understood that the continuous extending wall is a complete wall, rather than multiple walls connected together. Alternatively, multiple walls can be arranged along the circumference of the atomizer 1 and connected end to end to form the annular opening 22a. In this case, if at least one of the walls is set to be movable, the periphery of the annular opening 22a can be opened, and the atomizer 1 can either pass through the annular opening 22a along its axial direction or be positioned within the annular opening 22a from the opened area of ​​the annular opening 22a.

[0136] In this embodiment, the fixing unit 22 can be regarded as surrounding the atomizer 1 for a whole circumference, or the fixing unit 22 and the power supply unit 21 together form a structure surrounding the atomizer 1 for a whole circumference. In this way, the displacement of the atomizer 1 in any direction on the plane perpendicular to the first direction can be effectively limited, which is conducive to further improving the stability of the position of the atomizer 1 on the power supply unit 2.

[0137] In some embodiments, please refer to FIG6 or FIG12, the fixing unit 22 includes a first arm body 221 and a second arm body 222. One end of the first arm body 221 and one end of the second arm body 222 are connected. The other end of the first arm body 221 and the other end of the second arm body 222 are spaced apart in the circumferential direction of the atomizer 1, and a gap 22b is formed between them.

[0138] It should be noted that, as shown in Figure 6, one end of the first arm 221 and one end of the second arm 222 can be directly connected; as shown in Figure 12, one end of the first arm 221 and one end of the second arm 222 can also be connected to the power supply unit 21 respectively.

[0139] In this way, when installing the atomizer 1, it can be moved to the target installation position through the spacer opening 22b in a direction perpendicular to the first direction. Similarly, when disassembling the atomizer 1, it can also be disassembled through the spacer opening 22b in a direction perpendicular to the first direction. That is, in this embodiment, the atomizer 1 can be installed and disassembled in directions other than the first direction. Furthermore, the first arm 221 and the second arm 222 can also be configured to have a certain degree of elasticity. This improves the ease of installation and disassembly of the atomizer 1.

[0140] In some embodiments, please refer to Figure 6 or Figure 12. The line connecting the two ends of the orthographic projection of the spacer 22b on a plane perpendicular to the first direction is a reference line. The direction in which the reference line is located is the second direction. The maximum dimension of the atomizer 1 in the second direction is not less than the length dimension of the reference line.

[0141] Here, the length of the reference line is the spacing of the gap 22b in the second direction.

[0142] It is understandable that the spacing of the gap 22b in the second direction is set to be less than or equal to the maximum dimension of the atomizer 1 in the second direction. In this way, the atomizer 1 will not detach from the gap 22b if the positional state of the first arm 221 and the second arm 222 does not change, which helps to improve the fixing effect of the fixing unit 22 on the atomizer 1.

[0143] In some embodiments, the fixing unit 22 is at least capable of elastic deformation in a plane perpendicular to the first direction.

[0144] Here, in the embodiment shown in FIG5, the fixing unit 22 is provided with an annular opening 22a, or in the embodiment shown in FIG11, the fixing unit 22 and the power supply unit 21 surround to form an annular opening 22a, the fixing unit 22 is made of a material that can produce elastic deformation.

[0145] In an embodiment of the fixing unit 22 shown in Figure 6 or Figure 12, which includes a first arm 221 and a second arm 222, at least one of the first arm 221 and the second arm 222 is made of a material capable of elastic deformation.

[0146] Specifically, these materials capable of elastic deformation include, but are not limited to, metal elastic products (such as spring steel, thin metal sheets, etc.), polymer elastomers (such as thermoplastic polyurethane, polyether block amide, ethylene-vinyl acetate copolymer, etc.), composite materials (such as carbon fiber reinforced rubber, glass fiber / epoxy resin prepreg, metal rubber, etc.), natural rubber, silicone rubber, fluororubber, etc.

[0147] Based on the embodiment that forms the annular opening 22a, the fixing unit 22 can change the diameter of the annular opening 22a by generating elastic deformation, so that the annular opening 22a can be adapted to atomizers 1 of different sizes.

[0148] In an embodiment based on the fixed unit 22 with the spacer opening 22b, the first arm 221 and / or the second arm 222 can change the size of the spacer opening 22b by generating elastic deformation, thereby facilitating the atomizer 1 to be installed and removed from the power supply assembly 2 through the spacer opening 22b.

[0149] In this embodiment, by allowing at least a portion of the structure of the fixing unit 22 to undergo elastic deformation, the atomizer 1 can be easily disassembled and assembled. The fixing unit 22 does not need to be provided with other structures (such as the rotatable structure in the following embodiment) to change the size of its annular opening 22a or the spacer opening 22b. This helps to simplify the structure of the power supply assembly 2 and improve the production efficiency of the power supply assembly 2.

[0150] In some embodiments, as shown in Figure 6 or Figure 12, at least one of one end of the first arm 221 and one end of the second arm 222 is rotatably disposed along the circumference of the atomizer 1.

[0151] Here, it is possible that only one of the first arm 221 and the second arm 222 is rotatable, or initially both can be rotatable.

[0152] Here, as shown in Figure 6, when one end of the first arm 221 and one end of the second arm 222 are directly connected, one end of one arm 221 is rotatably connected to one end of the other; as shown in Figure 12, when one end of the first arm 221 and one end of the second arm 222 are respectively connected to the power supply unit 21 to achieve indirect connection, at least one of the ends of the first arm 221 and the second arm 222 is rotatably provided on the power supply unit 21.

[0153] In this embodiment, the size of the spacer opening 22b can be changed by rotating the first arm 221 and / or the second arm 222. Thus, during the assembly and disassembly of the atomizer 1, rotating the first arm 221 and / or the second arm 222 increases the size of the spacer opening 22b, making it easier to assemble and disassemble the atomizer 1 through the spacer opening 22b. After the atomizer 1 is assembled, rotating the first arm 221 and / or the second arm 222 further reduces the size of the spacer opening 22b, thereby improving the enclosure effect of the first arm 221 and the second arm 222 on the atomizer 1. This improves the stability and reliability of the atomizer 1's installation on the power supply assembly 2.

[0154] In addition, the operation of rotating the first arm 221 and / or the second arm 222 is relatively simple and easy for users to operate.

[0155] Furthermore, compared to embodiments that change the size of the gap 22b by causing elastic deformation of the first arm 221 and / or the second arm 222, in this embodiment, by rotatably configuring the first arm 221 and / or the second arm 222, the size of the gap 22b can be changed without altering the shape of the first arm 221 and / or the second arm 222. This helps to alleviate the stress concentration problem of the first arm 221 and / or the second arm 222, and consequently, helps to alleviate the fatigue problem of the first arm 221 and / or the second arm 222, thus extending the service life of the first arm 221 and / or the second arm 222.

[0156] In this embodiment, since the size of the gap 22b can be adjusted by rotating the first arm 221 and / or the second arm 222, the first arm 221 and / or the second arm 222 can also be made of materials that are difficult to undergo elastic deformation. This allows for a wider range of material choices for the first arm 221 and / or the second arm 222, facilitating their production.

[0157] In some embodiments, please refer to Figures 2 to 4, or Figures 8 to 10, or Figures 15 to 17, at least a portion of the first partial surface 21a1 is a planar region 21a11, the end face of the bottom end 1b of the shell is disposed opposite to the planar region 21a11, and the other regions of the first partial surface 21a1 other than the planar region 21a11 are peripheral surfaces 21a12, which surround the outer periphery of the planar region 21a11.

[0158] It is understandable that when the entire area of ​​the first part surface 21a1 is a planar area 21a11, then the first part surface 21a1 does not have an outer surface 21a12.

[0159] It should be noted that the vector direction of this vector difference is from the suction end 1a to the bottom end 1b of the shell.

[0160] It is understandable that when the vector difference is greater than 0, it means that the height of at least a part of the outer surface 21a12 is higher than the height of the planar region 21a11; when the vector difference is less than or equal to 0, it means that the height of all areas of the outer surface 21a12 does not exceed the height of the planar region 21a11.

[0161] In this embodiment, the first part surface 21a1 has a planar region 21a11. The planar region 21a11 is relatively easy to process and easy to form. Therefore, it is beneficial to reduce the processing difficulty of the first part surface 21a1, thereby improving the production efficiency of the power supply component 2.

[0162] In some embodiments, as shown in Figures 4 or 10, 14 and 15, or 19 and 20, or 23 to 25, the end face of the bottom end 1b of the shell abuts against the first partial surface 21a1. In this way, the first partial surface 21a1 can bear a portion of the weight of the atomizer 1, which helps to alleviate the torque on the physical connection structure between the atomizer 1 and the power supply assembly 2, thereby improving the reliability of this physical connection structure and extending its service life.

[0163] In some embodiments, please refer to Figure 4 or Figure 10. The point furthest from the suction end 1a on the end face of the bottom end 1b of the shell is the first point, and the point closest to the suction end 1a on the first partial surface 21a1 is the second point. The distance between the first point and the suction end 1a is not greater than the distance between the second point and the suction end 1a.

[0164] In other words, the lowest point of the atomizer 1 is higher than or level with the highest point of the first part surface 21a1.

[0165] In this embodiment, even when the atomizer 1 approaches or moves away from the power assembly 2 in a direction perpendicular to the first direction, and the atomizer 1 is removed from the power assembly 2, there will be no interference between the bottom end of the atomizer 1 and the first part surface 21a1. This makes it easier to remove and install the atomizer 1.

[0166] In some embodiments, please refer to Figures 1 to 4, Figures 18 to 21, or Figures 22 to 26, the atomizer 1 is disposed at one end of the power supply unit 21 along the first direction, and the entire outer edge of the first partial surface 21a1 constitutes the entire outer edge of the first region surface 21a.

[0167] Here, the aerosol generating device is roughly rod-shaped. The rod-shaped aerosol generating device has a relatively small opening diameter on a plane perpendicular to the first direction, making it easy for the user to hold and use.

[0168] Here, the power supply area of ​​the power supply unit 21 can be set on the first part surface 21a1, and the power receiving area of ​​the atomizer 1 can be set on the end face of the bottom end 1b of the shell; when there is a physical connection structure between the power supply unit 21 and the atomizer 1, they can also be set on the first part surface 21a1 and the end face of the bottom end 1b of the shell, respectively.

[0169] In this embodiment, the atomizer 1 and / or the power supply unit 21 are not limited to being cylindrical; they can also be other shapes such as elliptical or square columns.

[0170] In some embodiments, please refer to Figures 1 and 2. The power supply assembly 2 also includes a support unit 23. One end of the support unit 23 is disposed on the power supply part 21, and the other end extends along a first direction toward the side away from the first partial surface 21a1. The fixing unit 22 is disposed at the other end of the support unit 23.

[0171] It should be noted that the support unit 23 and the fixing unit 22 can be an integral structure or a separate structure, and this application does not impose any restrictions on them.

[0172] A portion of the support unit 23 is located on the periphery of the atomizer 1, and the fixing unit 22 is connected to the power supply unit 21 through the support unit 23.

[0173] The specific structure of the support unit 23 is not limited. For example, please refer to FIG2. The support unit 23 includes a collar 231 and a support wall 232. The collar 231 is sleeved on one end of the power supply part 21 near the bottom end 1b of the housing. The two ends of the support wall 232 are respectively connected to the collar 231 and the fixing unit 22.

[0174] In some embodiments, please refer to Figures 7 to 10, or Figures 13 to 17, the power supply unit 21 includes a first body 2111 and a second body 212. In a first direction, the extension dimension of the first body 2111 is smaller than the extension dimension of the second body 212. The first body 2111 is located on the periphery of the second body 212. The first region surface 21a also includes a second part surface 21a2 that is spaced apart from the first part surface 21a1. The second part surface 21a2 is the end face of the second body 212 away from the bottom end 1b of the shell.

[0175] The peripheral side surface of the second body 212 includes a third part surface 212a. The two ends of the third part surface 212a are connected to the first part surface 21a1 and the second part surface 21a2 respectively. The third part surface 212a is arranged opposite to the peripheral side surface of the atomizer 1.

[0176] The height of the second part surface 21a2 is higher than the height of the first part surface 21a1. The power supply unit 21 is approximately L-shaped. In this embodiment, the aerosol generating device is approximately box-shaped. The box-shaped aerosol generating device has a larger diameter on the plane perpendicular to the first direction, which can appropriately increase the capacity of the power supply unit 21. After the power supply unit 21 is fully charged, the usage time is relatively long, which helps to reduce the number of times the user needs to charge and improves the user experience.

[0177] In addition, the boxed aerosol generating device is relatively short in the first direction, meaning that the size of the aerosol generating device is moderate in all directions, making it easy for users to carry.

[0178] Here, the power receiving area and the power supply area can be respectively set on the end face of the bottom end 1b of the shell and the first part surface 21a1, or they can be respectively set on the peripheral side surface and the third part surface 212a of the atomizer 1.

[0179] Here, when the atomizer 1 and the power supply assembly 2 are physically connected, the physical connection structure can be respectively set on the end face of the bottom end 1b of the shell and the first part surface 21a1, or it can be respectively set on the peripheral side surface and the third part surface 212a of the atomizer 1.

[0180] Here, when the physical connection and electrical connection between the atomizer 1 and the power supply component 2 adopt two sets of connection structures, the electrical connection structure and the physical connection structure of the power supply component 2 can be respectively set on the first part surface 21a1 and the third part surface 212a, or they can both be set on the first part surface 21a1 or both on the third part surface 212a.

[0181] The fixing unit 22 is connected to the second partial surface 21a2 and / or the third partial surface 212a.

[0182] Here, the fixed unit 22 may be connected only to the second part surface 21a2; or it may be connected only to the third part surface 212a; or it may be connected to both the second part surface 21a2 and the third part surface 212a.

[0183] The fixing unit 22 and the power supply unit 21 can be an integral structure or a separate structure, and this application does not impose any restrictions on them.

[0184] In some embodiments, referring to Figures 8 and 17, a reference cross-section is obtained by cutting the third portion of the surface 212a with a plane perpendicular to the first direction. The reference cross-section is a groove-shaped cross-section. Here, the side of the groove-shaped cross-section facing the atomizer 1 can be completely open or partially open, which is not limited in this application. Here, the third portion of the surface 212a can be a curved surface; it can also be composed of multiple surfaces that surround the first direction as an axis and are connected in sequence. Here, any one of the multiple surfaces can be a plane or a curved surface.

[0185] In this embodiment, the third part 212a surrounds and forms a groove-shaped area. A part of the atomizer 1 can extend into the groove-shaped area. The groove-shaped area can wrap around a part of the peripheral side of the atomizer 1, thereby producing a certain positioning effect on the atomizer 1. This helps to improve the stability and reliability of the atomizer 1 when it is installed on the power supply assembly 2.

[0186] Furthermore, since the third part 212a has a certain surrounding effect on the atomizer 1, there are more areas on the peripheral side of the atomizer 1 that can be used to realize electrical and / or physical connection with the power supply component 2, which makes it easier to set electrical and / or physical connection structures on the atomizer 1.

[0187] In some embodiments, the third partial surface 212a is a plane. Here, it means that the third partial surface 212a as a whole is a plane.

[0188] In this way, in the direction parallel to the third part surface 212a, the third part surface 212a will not restrict the atomizer 1. When the atomizer 1 is disassembled or assembled in the direction parallel to the third part surface 212a, there will be no interference between the third part surface 212a and the peripheral side surface of the atomizer 1, thereby further facilitating the disassembly and assembly of the atomizer 1.

[0189] In some embodiments, please refer to Figures 3 and 4, or Figures 9 and 10, 16, 20, 23 and 24. The atomizer 1 includes an atomizing core 11 and a housing assembly 12 having a suction end 1a and a bottom end 1b. The atomizing core 11 is disposed inside the housing assembly 12. The housing assembly 12 is provided with a liquid storage chamber 12a for storing the aerosol generation matrix. The liquid storage chamber 12a is in liquid communication with the atomizing core 11.

[0190] The liquid connection between the liquid storage chamber 12a and the atomizing core 11 means that the aerosol generation matrix in the liquid storage chamber 12a can be guided to the atomizing core 11.

[0191] The atomizing core 11 generally includes a liquid guiding element and a heating element. The heating element converts electrical energy into other forms of energy and applies them to the aerosol generating matrix, thereby heating and atomizing the aerosol generating matrix to generate aerosols. The liquid guiding element transports or delivers the aerosol generating matrix to the heating element through capillary forces or other forces, including but not limited to ceramics, glass, quartz, or fibers. Of course, in some cases, the liquid guiding element can be omitted.

[0192] The specific method by which the heating element heats the aerosol to form a matrix is ​​not limited. Examples include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc.

[0193] Specifically, the heating element that uses resistance heating is called a heating element. The heating element can convert electrical energy into heat energy, thereby heating the aerosol generation matrix to generate aerosols.

[0194] There are no restrictions on the specific type of heating element. For example, it can be a heating needle, heating film, heating mesh, heating plate, or heating wire, etc.

[0195] In one specific embodiment, please refer to Figures 4 or 10, 16, 20 and 24. The atomizer 1 includes an atomizing core 11, a housing assembly 12 and an atomizing seat 13. The housing assembly 12 is provided with a liquid storage chamber 12a and one side of the housing assembly 12 is open. Specifically, one side of the liquid storage chamber 12a may be open. The atomizing seat 13 is located on the open side of the housing assembly 12 and is provided with an atomizing chamber 13a. The atomizing core 11 is located in the atomizing chamber 13a.

[0196] The materials used to prepare the atomizing base 13 include, but are not limited to, porous ceramics, porous metals, porous glass, silicone, and plastics.

[0197] It should be noted that the direction in which the atomizing core 11 generates the atomized aerosol matrix is ​​not limited. For example, please refer to Figure 4 or Figure 10. The housing assembly 12 is provided with an air outlet channel 12b. The direction of the atomizing core 11 is directly opposite to the axial direction of the air outlet channel 12b or tilted at a certain angle relative to the axial direction of the air outlet channel 12b.

[0198] Here, the specific direction of the axial direction of the air outlet channel 12b is not limited. For example, it can be a direction that is nearly parallel to the first direction, as shown in Figure 4 or Figure 10, that is, nearly parallel to the height direction of the aerosol generating device; or, the air outlet channel 12b can also extend in a direction perpendicular to the first direction.

[0199] In some embodiments, the number of atomizing cores 11 is multiple.

[0200] In some embodiments where the number of atomizing cores 11 is multiple, at least two atomizing chambers 13a are connected in series. This facilitates the atomizing of different flavored aerosol generating matrices by multiple atomizing cores 11 and the mixing of the generated aerosols of different flavors, thereby enriching the taste of the aerosols produced by the aerosol generating device.

[0201] In some embodiments, there are multiple liquid storage chambers 12a, and multiple atomizing cores 11 are respectively connected to different liquid storage chambers 12a.

[0202] In some embodiments, the atomizing chambers 13a connected in series are connected to the same air outlet channel 12b.

[0203] In some embodiments where there are multiple atomizing chambers 13a, the atomizing chambers 13a are connected in parallel. This allows the aerosol generated by each atomizing core 11 to be independently discharged for the user to inhale, and the different atomizing cores 11 can be atomizing aerosol generating matrices of different flavors.

[0204] In some embodiments, there are multiple liquid storage chambers 12a, and the atomizing chambers 13a connected in parallel are respectively connected to different liquid storage chambers 12a.

[0205] In some embodiments, the atomizing chambers 13a connected in parallel are respectively connected to different air outlet channels 12b, so that the user can independently inhale the aerosol discharged from any atomizing chamber 13a.

[0206] In some embodiments, the atomizing chambers 13a connected in parallel can be selectively connected to the same air outlet channel 12b. That is, any one of the multiple atomizing chambers 13a connected in parallel can be selectively connected to or isolated from the air outlet channel 12b, so that the user can independently inhale the aerosol discharged from any one atomizing chamber 13a, or the aerosol discharged from some or all of the multiple atomizing chambers 13a connected in parallel can be mixed before being inhaled by the user, which helps to enrich the user experience.

[0207] In some embodiments, the power supply assembly 2 is electrically connected to the atomizing core 11 to supply power to the atomizing core 11. In this way, the atomizer 1 is mainly used to contain the aerosol generating matrix and heat and atomize the aerosol generating matrix to generate aerosol after being powered on. The power source for the atomizing core 11 does not need to be provided by the atomizer 1. Therefore, it is beneficial to save space in the atomizer 1 so that the atomizer 1 can contain more aerosol generating matrix and increase the service life of the atomizer 1.

[0208] In some embodiments, the atomizer 1 further includes a battery assembly electrically connected to the atomizer core 11, and a power supply assembly 2 electrically connected to the battery assembly to charge the battery assembly. Here, the battery assembly directly supplies power to the atomizer core 11, and the power supply assembly 2 supplements the battery assembly's electrical energy. In this embodiment, the atomizer 1 can generate aerosols by operating independently, thus facilitating user operation.

[0209] In some embodiments, the housing assembly 12 includes a first housing portion and a second housing portion detachably connected along a first direction. The end of the first housing portion away from the second housing portion is a suction end 1a, and the end of the second housing portion away from the first housing portion is a bottom end 1b. The atomizing core 11 is disposed in the second housing portion. The liquid storage chamber 12a includes a first liquid storage chamber and a second liquid storage chamber. The first liquid storage chamber is disposed in the first housing portion, and the second liquid storage chamber is disposed in the second housing portion. The first liquid storage chamber is in liquid communication with the atomizing core 11 through the second liquid storage chamber.

[0210] For example, the second liquid storage chamber can directly store the liquid aerosol generation matrix, or an adsorbent material can be provided in the second liquid storage chamber to adsorb a certain amount of aerosol generation matrix.

[0211] The first and second liquid storage tanks have the same capacity, or the capacity of the first liquid storage tank is twice or more the capacity of the second liquid storage tank.

[0212] In one specific embodiment, the second shell can accommodate aerosol generation matrix of different volumes, such as 2 ml, 5 ml, 10 ml, etc.

[0213] In this embodiment, the first shell is integral and the second shell is detachably connected. Detachable connection methods include, but are not limited to, magnetic connection, snap-fit, plug-in connection, threaded connection, etc. After the aerosol generating matrix stored in the first liquid reservoir is used up, the entire first shell or atomizer 1 containing the aerosol generating matrix can be replaced, while the second shell can continue to be used. This helps reduce the user's operating costs.

[0214] This application provides an aerosol generating device. Please refer to Figure 13, Figure 18 or Figure 22. The aerosol generating device includes an atomizer 1, a power supply assembly 2 and an outer casing assembly 3.

[0215] The outer sleeve assembly 3 surrounds the atomizer 1 with the first direction as its axis and is connected to the atomizer 1. That is, the outer sleeve assembly 3 is arranged around the periphery of the atomizer 1. It should be noted that the outer sleeve assembly 3 can surround the atomizer 1 for a full circumference along the circumference of the atomizer 1, or it can surround the atomizer 1 for less than a full circumference.

[0216] It should be noted that, in the embodiments of this application, the circumferential direction of the atomizer 1 refers to the clockwise or counterclockwise rotation direction about the first direction as the axis.

[0217] In some embodiments, referring to Figure 16, the atomizer 1 and the power supply assembly 2 may not be directly connected to achieve a physical connection between them. For example, the outer casing assembly 3 is physically connected to the power supply assembly 2, so that the atomizer 1 can be stably installed on the power supply assembly 2 through the outer casing assembly 3.

[0218] The outer casing 3 encloses the atomizer 1, providing protection for it. Both the physical and electrical connections between the atomizer 1 and the power supply component 2 are protected by the outer casing 3, thus improving the reliability and stability of both the electrical and physical connections. Simultaneously, on a plane perpendicular to the first direction, the outer casing 3 effectively fills the dimensional difference between the atomizer 1 and the power supply component 2, mitigating the stepped surface issue on the aerosol generator's periphery. This results in a better grip and a more aesthetically pleasing aerosol generator.

[0219] The aerosol generating device of this application embodiment has strong visibility of the atomizer 1, which also facilitates cleaning and maintenance of the surface of the power supply component 2 used to cooperate with the atomizer 1. The assembly of the atomizer 1 and the power supply component 2 is relatively simple, which helps to reduce production costs and improve production efficiency. At the same time, the atomizer 1 has a large exposed area on the power supply component 2, which provides better heat dissipation.

[0220] The outer casing assembly 3 is connected to the atomizer 1.

[0221] In some embodiments, referring to Figures 18 to 21, the outer casing assembly 3 is also connected to the power supply assembly 2, and the connection strength between the outer casing assembly 3 and the atomizer 1 is greater than the connection strength between the outer casing assembly 3 and the power supply assembly 2. Here, the connection between the outer casing assembly 3 and the power supply assembly 2 refers to a physical connection.

[0222] In this way, when the atomizer 1 is unplugged from the power assembly 2, the outer sleeve assembly 3 will separate from the power assembly 2, thus being detached from the power assembly 2 as a whole with the atomizer 1. Therefore, when replacing the atomizer 1, it is not necessary to separately remove the outer sleeve assembly 3 from the power assembly 2, which simplifies the replacement process, improves the replacement efficiency of the atomizer 1, and enhances the user experience.

[0223] Of course, in some embodiments, please refer to Figures 13 to 15, the outer casing assembly 3 and the power supply assembly 2 may not be connected together. The outer casing assembly 3 and the atomizer 1 are integrated as a whole, and the atomizer 1 is stably installed on the power supply assembly 2 through the physical connection structure between the atomizer 1 and the power supply assembly 2.

[0224] It should be noted that there are no restrictions on the connection method between the outer casing component 3 and the atomizer 1. For example, it can be a magnetic connection, a snap-fit ​​connection, an interference fit connection, etc.

[0225] In some embodiments, as shown in Figures 18 and 21, one of the peripheral side surface of the atomizer 1 and the peripheral side surface of the outer casing assembly 3 is provided with a snap-fit ​​protrusion 1c, and the other is provided with a snap-fit ​​groove 3a. Specifically, taking the example of a snap-fit ​​groove 3a on the peripheral side of the outer casing assembly 3 and a snap-fit ​​protrusion 1c on the peripheral side of the atomizer 1, the snap-fit ​​groove 3a includes a first groove 3a1 and a second groove 3a2. The first groove 3a1 extends along a first direction and one end penetrates the end wall of the outer casing assembly 3 near the suction end 1a (i.e., the top wall of the outer casing assembly 3). One end of the second groove 3a2 is connected to the other end of the first groove 3a1 and extends along the circumference of the outer casing assembly 3 (the circumference of the outer casing assembly 3 is the circumference of the atomizer 1). The snap-fit ​​protrusion 1c slides into the first groove 3a1 from one end and slides to the other end of the first groove 3a1. Then, by rotating the atomizer 1, the snap-fit ​​protrusion 1c slides into the second groove 3a2. In this way, the snap-fit ​​between the atomizer 1 and the outer casing assembly 3 is achieved. When disassembling the outer casing assembly 3 and the atomizer 1, the atomizer 1 is first rotated so that the locking protrusion 1c slides to the position where the second slide groove 3a2 communicates with the first slide groove 3a1. Then, the atomizer 1 can be pulled off along the first direction. In this embodiment, the disassembly and assembly operations between the atomizer 1 and the outer casing assembly 3 are relatively convenient and easy for the user to operate. At the same time, when the atomizer 1 and the outer casing assembly 3 are in the locking state, the groove wall of the second slide groove 3a2 forms a stop against the locking protrusion 1c, which helps to improve the reliability of the atomizer 1 and the outer casing assembly 3 in the locking state. This allows the atomizer 1 to be more stably and reliably detached from the power supply assembly 2 along with the outer casing assembly 3.

[0226] In some embodiments, the outer casing assembly 3 and the atomizer 1 are integrally formed. Here, at least a portion of the structure of the outer casing assembly 3 and the atomizer 1 is integrally formed. In this embodiment, the atomizer 1 and the outer casing assembly 3 are not assembled structures; the integrally formed structure offers better connection reliability compared to an assembled structure. It is understood that in this embodiment, when the atomizer 1 is replaced in the aerosol generating device, the outer casing assembly 3 will be replaced simultaneously.

[0227] In some embodiments, the outer casing assembly 3 includes an outer casing and a clamping member. The outer casing surrounds the outer casing with a first direction as its axis and forms a receiving area. The clamping member is disposed in the receiving area and can undergo elastic deformation in a plane perpendicular to the first direction. At least a portion of the atomizer 1 is disposed in the receiving area, and the clamping member abuts against the peripheral sidewall of the atomizer 1.

[0228] It should be noted that in this embodiment, when the outer casing assembly 3 and the power supply assembly 2 form a physical connection, the physical connection is formed between the outer casing and the power supply assembly 2; the snap-fit ​​protrusion 1c or snap-fit ​​groove 3a mentioned above are also structures on the outer casing; in embodiments where the outer casing assembly 3 and the atomizer 1 are integrally formed, it refers to the outer casing and the atomizer 1 being integrally formed.

[0229] There are no restrictions on the material of the outer kit.

[0230] For example, the outer casing can be made of a transparent material, such as glass or transparent plastic. This allows the structure of the atomizer 1 within the housing area to be observed through the outer casing, thus facilitating the assembly of the atomizer 1.

[0231] For example, the outer casing can also be made of metal. This makes it easier to process structures such as snap-fit ​​protrusions 1c and snap-fit ​​grooves 3a on the outer casing, which helps to reduce the processing difficulty of the outer casing, thereby improving the production efficiency of the outer casing and reducing the processing cost of the outer casing.

[0232] The specific type of clamping element is not limited. For example, it can be a spring, or an article made of materials that can produce elastic deformation, such as rubber, silicone, or fiber.

[0233] In this embodiment, the passable space of the receiving area is adjustable. When no atomizer 1 is placed in the receiving area, the clamping member is in a free state. Based on the atomizers 1 with different diameters on a plane perpendicular to the first direction, the clamping member can undergo elastic deformation, allowing atomizers 1 with different diameters to be placed in the receiving area. Furthermore, the clamping member abuts against the peripheral side of the atomizer 1 under the action of elastic restoring force. In this way, the outer sleeve assembly 3 can accommodate more atomizers 1 with different diameters. At the same time, clamping the atomizer 1 with the clamping member also helps to improve the connection reliability between the atomizer 1 and the outer sleeve assembly 3.

[0234] In some embodiments, as shown in Figures 13 to 15, the end of the outer casing assembly 3 away from the suction end 1a is flush with the bottom end 1b of the casing.

[0235] In this way, the disassembly and assembly of the outer casing assembly 3 will not be affected by the first part surface 21a1. When the outer casing assembly 3 and the atomizer 1 are disassembled and assembled as a whole, there will be no interference with the first part surface 21a1, which is beneficial to the disassembly and assembly of the whole on the power supply assembly 2.

[0236] In some embodiments, see Figures 19 and 20, or Figures 23 to 25, the end of the outer casing assembly 3 away from the suction end 1a extends beyond the bottom end 1b of the housing, and the portion of the outer casing assembly 3 extending beyond the bottom end 1b of the housing is fitted onto the power supply assembly 2.

[0237] Specifically, when the outer casing component 3 includes an outer sleeve, it means that the outer sleeve is fitted onto the power supply component 2.

[0238] It should be noted that the "sleeving" here can simply mean that the outer casing 3 surrounds the power supply component 2, but there is no force between the outer casing 3 and the power supply component 2. In this way, the force required to assemble and disassemble the outer casing 3 and the atomizer 1 as a whole from the power supply component 2 is also smaller, making the operation easier for the user.

[0239] Of course, the casing assembly 3 can also be positioned around the power supply assembly 2, creating a physical connection between them. This could be achieved through an interference fit, snap-fit, magnetic connection, threaded connection, etc. This improves the stability and reliability of the casing assembly 3 and the atomizer 1 as a whole on the power supply assembly 2.

[0240] In this embodiment, since the portion of the outer casing assembly 3 extending beyond the bottom end 1b of the shell is fitted onto the power supply assembly 2, both the first partial surface 21a1 and the end face of the bottom end 1b of the shell are covered by the outer casing assembly 3. Thus, the physical connection structure and / or electrical connection structure provided on the first partial surface 21a1 and the end face of the bottom end 1b of the shell can be protected by the outer casing assembly 3, thereby improving the stability and reliability of the electrical connection and / or physical connection between the atomizer 1 and the power supply assembly 2.

[0241] In some embodiments, referring to Figures 16 and 17, in any direction perpendicular to the first direction, the outer edge of the end face of the outer jacket assembly 3 away from the suction end 1a does not extend beyond the outer edge of the first partial surface 21a1.

[0242] That is, when projected orthogonally along the first direction, the orthogonal projection of the end face of the outer casing assembly 3 away from the suction end 1a is within the range of the orthogonal projection of the first partial surface 21a1.

[0243] It is understandable that the orthographic projection of the end face of the outer casing assembly 3 away from the suction end 1a may be exactly the same size as the orthographic projection of the first part surface 21a1, thus achieving overlap. Alternatively, the area of ​​the orthographic projection of the end face of the outer casing assembly 3 away from the suction end 1a may be smaller than the area of ​​the orthographic projection of the first part surface 21a1, thereby making the orthographic projection of the end face of the outer casing assembly 3 away from the suction end 1a fall within the range of the orthographic projection of the first part surface 21a1.

[0244] In this embodiment, the end of the outer casing assembly 3 furthest from the suction end 1a is completely blocked by the first partial surface 21a1, making it more difficult for debris and other impurities to enter the receiving area through the end of the outer casing assembly 3 furthest from the suction end 1a. This helps reduce the likelihood of debris jamming the connection between the atomizer 1 and the outer casing assembly 3, thus preventing the atomizer 1 from being disconnected.

[0245] In some embodiments, please refer to FIG5, a first connecting portion is provided on the peripheral side of the atomizer 1, and a second connecting portion is provided on the third part surface 212a, and the first connecting portion is connected to the second connecting portion.

[0246] The connection structure between the first connecting part and the second connecting part is not limited. For example, it can be a magnetic connection structure, a snap-fit ​​connection structure, a plug-in connection structure, etc.

[0247] In this embodiment, the connection structure between the atomizer 1 and the power supply assembly 2 is located on the periphery of the atomizer 1 and the periphery of the second body 212. In this way, the end face of the bottom end 1b of the atomizer 1 shell can fit better with the first partial surface 21a1, and the fitting area can be larger, thereby better supporting the atomizer 1.

[0248] In some embodiments, the first body 211 further has a second state in which the first body 211 is located at one end of the second body 212 along a first direction, and the atomizer 1 is located at the end of the first body 211 away from the second body 212. The end face of the first body 211 away from the second body 212 is a first partial surface 21a1, and all the outer edges of the first partial surface 21a1 constitute all the outer edges of the first region surface 21a. That is, when the first body 211 is in the second state, the first region surface 21a only includes the first partial surface 21a1.

[0249] Here, the first main body 211 is in the second state, and after the atomizer 1 and the power supply component 2 are electrically connected, the aerosol generating device is roughly rod-shaped.

[0250] In this embodiment, the first main body 211 switches between a first state and a second state, thereby enabling the aerosol generating device to switch between a rod-shaped form and a box-shaped form. The aerosol generating device has more forms, making it easier for users to switch between the forms according to their usage habits, thus facilitating user operation.

[0251] It should be noted that there are no restrictions on the specific way in which the first subject 211 switches between the first state and the second state.

[0252] In some embodiments, the second body 212 has mounting positions on its periphery and at one end along the first direction, and the first body 211 is detachably mounted at either mounting position. Thus, when it is necessary to change the state of the first body 211, the first body 211 can be removed from its current mounting position and then mounted at another mounting position.

[0253] It should be noted that the first body 211 and the second body 212 can be detachably connected by means of threaded connection, magnetic connection, snap-fit, plug-in connection, etc.

[0254] In some embodiments, a first body 211 is rotatably disposed on a second body 212, and the first body 211 rotates about the second body 212 to switch between a first state and a second state.

[0255] In this way, the first body 211 does not need to be completely removed from the second body 212 when switching states. For example, when it is necessary to switch the first body 211 from the first state to the second state, firstly, the stable relationship between the first body 211 and the second body 212 is released, then the first body 211 is rotated to the position of the second state, and then the first body 211 is fixed, so that the first body 211 can be switched to the second state and stably placed in the second state.

[0256] In this embodiment, the operation of switching between the first body 211 and the second body 212 in the first state and the second state is relatively simple and convenient for users.

[0257] It should be noted that a damping element can be provided between the first body 211 and the second body 212. The damping element can be, for example, a torsion spring. By providing a damping element, it is beneficial to improve the feel when operating the first body 211 relative to the second body 212, and the user experience is better.

[0258] In some embodiments, as shown in Figures 13 to 15, the end of the outer casing assembly 3 away from the suction end 1a is flush with the bottom end 1b of the casing.

[0259] In this way, the disassembly and assembly of the outer casing component 3 will not be affected by the first part surface 21a1. When the outer casing component 3 and the atomizer 1 are disassembled and assembled as a whole, there will be basically no interference with the first part surface 21a1, which is conducive to the disassembly and assembly of the whole on the power supply component 2.

[0260] In some embodiments, the end of the outer casing assembly 3 away from the suction end 1a extends beyond the bottom end 1b of the shell, and the portion of the outer casing assembly 3 extending beyond the bottom end 1b of the shell is fitted onto the first body 211.

[0261] Specifically, when the outer casing component 3 includes an outer cover, it means that the outer cover is fitted onto the first main body 211.

[0262] It should be noted that the "sleeving" here can simply mean that the outer casing 3 is placed around the outer periphery of the first main body 211, but there is no force between the outer casing 3 and the first main body 211. In this way, the force required to assemble and disassemble the outer casing 3 and the atomizer 1 as a whole from the first main body 211 is smaller, and the operation is less strenuous for the user.

[0263] Of course, the casing assembly 3 can also be positioned around the outer periphery of the first body 211 and physically connected to it. For example, it could be an interference fit, snap-fit, magnetic connection, threaded connection, etc. This improves the stability and reliability of the casing assembly 3 and the atomizer 1 as a whole on the first body 211.

[0264] In some embodiments, the surface where the heating element is located is orthogonal to or at an angle to the flow direction of the fluid in the atomizer 1. In some embodiments, the surface where the heating element is located is parallel to the flow direction of the fluid in the atomizer 1.

[0265] The location of the air inlet in the aerosol generating device of this application embodiment is not limited. External air can enter the atomizer 1 through the air inlet, thereby carrying the generated aerosol out through the suction end 1a for user use.

[0266] In some embodiments, the air inlet is located on the peripheral side of the atomizer 1 near the bottom end 1b of the housing.

[0267] Understandably, after the user stops inhaling, some of the generated aerosol will remain uninhaled and remain in the atomizer 1. This part of the aerosol is prone to condensation and forms condensate.

[0268] By placing the air inlet on the periphery of the atomizer 1, it is also beneficial to reduce the chance of condensate flowing out through the air inlet under the action of gravity and contaminating the power supply component 2.

[0269] In addition, air enters from the bottom area of ​​the atomizer 1 and flows out from the suction end 1a. In this way, the air path in the atomizer 1 is closer to a straight line, which helps to reduce the resistance of air flow, thereby reducing the suction resistance and making it easier for the user to inhale.

[0270] In some embodiments, the air inlet may also be located on the peripheral side of the power supply assembly 2.

[0271] In some embodiments, a gap may be provided between the outer casing and the peripheral wall of the atomizer 1 to allow air intake of the aerosol generating device.

[0272] In some embodiments, an air inlet groove is provided on the side wall of the receiving area, with one end of the air inlet groove penetrating the end face of the outer casing away from the bottom end 1b. In this way, even if the inner wall of the receiving area and the peripheral side wall of the atomizer 1 are in contact, the aerosol generating device can still intake air through the air inlet groove.

[0273] The various embodiments / implementations of this application can be combined with each other without creating contradictions.

[0274] The above description is merely a preferred technical solution in the embodiments of this application and is not intended to limit the protection scope of the embodiments of this application. For those skilled in the art, the embodiments of this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
