[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] like Figure 1 As shown, an embodiment of this application provides an aerosol generating device for heating and atomizing an aerosol generating matrix to generate aerosols for user use. The atomization method can be resistance heating, electromagnetic heating, infrared heating, laser heating, or microwave heating, and the heat transfer method can be convection, conduction, radiation, or a combination thereof. The aerosol generating matrix includes, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. The form of the aerosol generating matrix can be liquid, gel, paste, or solid. When the aerosol generating matrix is ​​solid, it can be in the form of pulverized, granulated, powdered, granular, strip-shaped, or flake-shaped solid. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and cosmetic purposes. For example, the aerosol generating matrix is ​​a liquid medicine or oil, or it is a plant-based material, such as plant roots, stems, leaves, flowers, buds, or seeds. The aerosol generating matrix can also be a material made primarily of plants with added aerosol-forming agents and fragrance materials.

[0040] This application does not specifically limit the type of aerosol generating device. For example, the aerosol generating device may be a medical nebulizer, an air humidifier, or an electronic cigarette, etc., that requires the use of a nebulizer 10.

[0041] The shape of the aerosol generating device is not limited; for example, it can be a square column, an elliptical column, a racetrack-shaped column, or a cylindrical shape, among other shapes.

[0042] like Figure 1 As shown, this application provides an aerosol generating device, which includes an atomizer 10 and a power supply assembly according to any embodiment of this application. The power supply assembly is electrically connected to the atomizer 10 and is mainly used to supply power to the atomizer 10 and control the opening and closing of the entire aerosol generating device 10. The atomizer 10 can be axially positioned above or below the power supply assembly, or it can be horizontally positioned to the side of the power supply assembly. The atomizer 10 and the power supply assembly can be detachably connected by means of threaded connection, magnetic connection, snap-fit ​​connection, etc. Of course, in other embodiments, the atomizer 10 and the power supply assembly can also be combined in a non-detachable manner.

[0043] like Figures 1 to 2 As shown, this application embodiment provides an atomizer 10. The atomizer 10 includes an atomizing core 1101, an atomizing assembly 110, and a base assembly 120. The atomizing assembly 110 has a first connecting portion 1102. The base assembly 120 has a second connecting portion 1201 that cooperates with the first connecting portion 1102. Through relative rotation between the first connecting portion 1102 and the second connecting portion 1201, the base assembly 120 can switch between a first position and a second position relative to the atomizing assembly 110. In the first position, the atomizing assembly 110 and the base assembly 120 form an atomizing cavity 1104, and the atomizing core 1101 is located in the atomizing cavity 1104. In the second position, the base assembly 120 is at least partially away from the atomizing assembly 110, exposing the surface of the atomizing core 1104.

[0044] Exemplarily, the atomizing core 1101 may only include an atomizing element that contacts at least a portion of the liquid guiding element 1103 and is capable of atomizing the liquid matrix on the liquid guiding element 1103 after being energized. The specific shape of the atomizing core 1101 is not limited; for example, it may be a mesh, array, or fabric formed of conductive filaments or conductive sheets, or a heating film formed by screen printing or deposition. The atomizing core 1101 may be disposed on the inner wall surface of the liquid guiding element 1103, or on the end face of the liquid guiding element 1103, or at other locations on the liquid guiding element 1103.

[0045] Exemplarily, the atomizing core 1101 may also include a liquid guiding element 1103 and an atomizing element. For example, the atomizing core 1101 includes a liquid guiding element 1103 and an atomizing element disposed on the liquid guiding element 1103. The liquid guiding element 1103 can be a porous liquid guiding element with wicking function, such as porous ceramics, porous metals, or fibrous materials such as cotton. The atomizing element includes, but is not limited to, a metal conductive wire, a metal conductive sheet, or a heating film. The shape of the liquid guiding element 1103 is not limited; for example, it can be various shapes such as tubular, rod-shaped, sheet-shaped, or bowl-shaped.

[0046] Of course, in other embodiments, the atomizing core 1101 may also adopt other atomizing structures, which may be one or more of the atomizing methods such as resistance heating, electromagnetic heating, infrared heating, chemical heating, ultrasonic atomization, and plasma heating.

[0047] For example, the first position (such as Figure 2 (As shown) This refers to the first connecting part 1102 and the second connecting part 1201 being in a closed state. In the first position, the upper part of the base assembly 120 surrounds the bottom of the atomizing assembly 110, and the base assembly 120 and the atomizing assembly 110 form an atomizing chamber 1104. The atomizing core 1102 is located inside the atomizing chamber 1104, so that the atomizing core 1101 is located in the atomizer 10. Of course, in other embodiments, the atomizing core 1101 can also be surrounded in the atomizer 10; in the second position (e.g.) Figure 4 As shown, the first connecting part 1102 and the second connecting part 1201 are in the open state. The relative rotation between the first connecting part 1102 and the second connecting part 1201 causes the base assembly 120 to move at least partially away from the atomizing assembly 110, exposing the surface of the atomizing core 1101. In this position, the surface of the atomizing core 1101 is exposed to the external environment, allowing the user to clean it directly, or the atomizing core 1101 to be removed for cleaning or replacement.

[0048] The second position can also be determined by the angle between the upper surface of the base assembly and the lower surface of the atomizing assembly. The second position is when the angle between the upper surface of the base assembly and the lower surface of the atomizing assembly is greater than 0 degrees.

[0049] In the first position, the atomizing core 1101 can be connected to the atomizing assembly 110 and / or the base assembly 120, and the atomizing core 1101 can be located on the atomizing assembly 110 and / or on the base assembly 120. In the second position, the atomizing core 1101 can also be connected to the atomizing assembly 110 and / or the base assembly 120, and the atomizing core 1101 can be located on the atomizing assembly 110 and / or on the base assembly 120.

[0050] In this application, by rotating relative to the first connecting part 1102 and the second connecting part 1201, the base assembly 120 can switch between a first position and a second position relative to the atomizing assembly 110, so that the atomizing core 1101 can be exposed to the external environment. This allows the user to clean the surface of the atomizing core, or remove it from the atomizer to clean or replace it with a new atomizing core, thereby improving the working efficiency of the atomizer.

[0051] Specifically, the first connecting portion 1102 and the second connecting portion 1201 are hinge structures. A hinge structure refers to a mechanical device used to connect two solids and allow relative rotation between them. The hinge structure is composed of movable components or is made of foldable materials. Furthermore, the hinge structure may include axial hinges, ball hinges, spring hinges, etc.

[0052] In some embodiments, the base assembly 120 can switch between a first position and a second position relative to the atomizing assembly 110 by relative rotation between the first connecting portion 1102 and the second connecting portion 1201. During the rotation, the position of one end of the base assembly relative to the atomizing assembly remains substantially unchanged, while the other end of the base assembly shifts away from the atomizing assembly. Here, "substantially unchanged position" can mean that the relative position remains completely unchanged, or that the relative position remains approximately unchanged; it can also mean that the connection position between one end of the base assembly and the atomizing assembly remains substantially unchanged.

[0053] In some embodiments, the base assembly 120 can switch between a first position and a second position relative to the atomizing assembly 110 by the relative rotation between the first connecting portion 1102 and the second connecting portion 1201, wherein the relative rotation between the first connecting portion 1102 and the second connecting portion 1201 includes at least one rotation center or rotation axis, and the second connecting portion switches between the first position and the second position along the at least one rotation center or rotation axis.

[0054] In some embodiments, the first connecting portion 1102 includes at least one rotating shaft 1108, and the second connecting portion 1201 includes at least one rotating sleeve 1109; and / or, the first connecting portion 1102 includes at least one rotating sleeve 1109, and the second connecting portion 1201 includes at least one rotating shaft 1108. That is, the first connecting portion 1102 and the second connecting portion 1201 are connected by a shaft-shaped hinge and are rotatably connected by the rotating shaft 1108. The rotating shaft 1108 can be one or more; the rotating sleeve 1109 can be one or more; the number of rotating shafts 1108 and rotating sleeves 1109 can be the same, or the number of rotating shafts 1108 and rotating sleeves 1109 can be different.

[0055] When the hinge structure is a rotating axis, the relative rotation between the first connecting part 1102 and the second connecting part 1201 is the rotating axis, and the second connecting part 1201 switches between a first position and a second position along at least one rotating axis.

[0056] The first connecting part 1102 and the second connecting part 1201 are rotatably connected by a rotating shaft 1108 and a rotating sleeve 1109. The direction of rotation can be one or more. The degree of rotational freedom can be one or more.

[0057] The central axis of the rotating shaft 1108 can be perpendicular to the axial direction of the atomizer 10. For example, the axial direction of the atomizer 10 (e.g., ...) Figure 2 Direction A shown is perpendicular to the central axis B of the rotation axis 1108. Here, considering assembly tolerances and manufacturing errors of parts, the parallelism and / or perpendicularity described herein can be completely parallel and / or completely perpendicular, or approximately parallel and / or approximately perpendicular.

[0058] In some embodiments, the cross-section of the atomizer 10 includes two opposing long sides 1106, which are perpendicular to the central axis of the rotation shaft 1108. The surface perpendicular to the axial direction of the atomizer 10 is its cross-section, which includes two opposing long sides 1106 and two opposing short sides 1107, with the long sides 1106 perpendicular to the central axis B of the rotation shaft 1108. With this configuration, after the first connecting portion 1102 and the second connecting portion 1201 move relative to each other, the atomizing assembly 110 can provide a sufficiently large opening, allowing ample space for cleaning or replacing the atomizer coil 1102.

[0059] In some embodiments, the sidewall of the rotating sleeve 1109 is provided with at least one slot 1110. The rotating sleeve 1109 includes a first rotating sleeve 1109a and a second rotating sleeve 1109b, wherein the second rotating sleeve 1109b is non-closed, meaning that the inner wall of the second rotating sleeve 1109b is arc-shaped and not a completely closed circle (e.g., Figure 6 As shown, the second rotating sleeve 1109b is provided with a slot 1110. During the installation of the atomizing component 110 and the base component 120, the rotating shaft 1108 is first inserted into the first rotating sleeve 1109a, and then the rotating shaft 1108 is inserted into the second rotating sleeve 1109b through the slot 1110. The disassembly process of the atomizing component 110 and the base component 120 is the reverse. This design facilitates the installation or disassembly of the atomizing component 110 and the base component 120.

[0060] In some embodiments, the rotating shaft 1108 includes at least one elastic element. The elastic element can be embedded in the rotating shaft 1108 to make the movement between the first connecting portion 1102 and the second connecting portion 1201 smoother and easier to open, etc.

[0061] In some embodiments, the hinge structure is a spherical hinge, and the first connecting portion 1102 and the second connecting portion 1201 rotate relative to each other via the spherical hinge. When the hinge structure is a spherical hinge, the relative rotation between the first connecting portion 1102 and the second connecting portion 1201 is the center of rotation, and the second connecting portion 1201 switches between a first position and a second position along at least one center of rotation.

[0062] In some embodiments, the first connecting portion 1102 is a groove, and the second connecting portion 1201 is a slider; and / or, the first connecting portion 1102 is a slider, and the second connecting portion 1201 is a groove. The first connecting portion 1102 and the second connecting portion 1201 are movably connected, with the first connecting portion 1102 moving relative to the second connecting portion 1201 along a fixed track. The first connecting portion 1102 and the second connecting portion 1201 may also adopt other matching methods, so that the atomizing coil is surrounded in the atomizer or exposed to the external environment through relative rotation between the two.

[0063] The atomizer includes a housing 130, inside which there is a liquid storage chamber 1301 and an air outlet channel 1302. The liquid storage chamber 1301 is used to contain the aerosol atomization matrix, and the air outlet channel 1302 is used to discharge the aerosol in the atomizer 10 for the user to inhale.

[0064] In some embodiments, the atomizing assembly 110 further includes an atomizing upper seat 1111, which is disposed at one end of the liquid storage chamber 1301, and has an inlet hole 1112 for introducing the aerosol atomizing matrix. Specifically, during normal use by the user, the atomizer 10 is oriented in a similar direction to... Figure 1 , Figure 2 As shown, the liquid storage chamber 1301 is located above the atomizing upper seat 1111, and the liquid inlet 1112 is located below the liquid storage chamber 1301. In this way, the aerosol atomizing matrix in the liquid storage chamber 1301 can automatically flow into the liquid inlet 1112 under the action of gravity.

[0065] In other embodiments, the atomizing assembly 110 further includes an elastic top cover 1113, which is disposed between the liquid storage chamber 1301 and the atomizing upper seat 1111. The housing 130 and the atomizing upper seat 1111 respectively abut against the elastic top cover 1113 to seal each other. Abutting can be understood as mutual compression or mutual contact, and sealing can be understood as the two objects being connected together without gaps at their contact points. It can be understood that the hardness of the housing 130 and the atomizing upper seat 1111 is higher than that of the elastic top cover 1113. Therefore, after the housing 130 and the atomizing upper seat 1111 abut against the elastic top cover 1113 respectively, the surface of the elastic top cover 1113 deforms, thereby filling the gaps between the inner wall of the housing 130 and the surface of the elastic top cover 1113, and between the surface of the atomizing upper seat 1111 and the surface of the elastic top cover 1113, thus achieving a seal.

[0066] In other embodiments, the atomizing assembly 110 further includes an elastic element 1114, which is disposed between the atomizing core 1101 and the atomizing upper seat 1111. The atomizing core 1101 and the atomizing upper seat 1111 respectively abut against the elastic element 1114 to seal the liquid inlet. Abutting can be understood as mutual compression or mutual contact, and sealing can be understood as the two objects being connected together without gaps at their contact points. It can be understood that the hardness of the atomizing core 1101 and the atomizing upper seat 1111 is higher than the hardness of the elastic element 1114. Therefore, after the atomizing core 1101 and the atomizing upper seat 1111 abut against the elastic element 1114, the surface of the elastic element 1114 deforms, thereby filling the gap between the surface of the atomizing upper seat 1111 and the surface of the atomizing core 1101, thus achieving a seal.

[0067] Furthermore, the base assembly 120 is positioned on the side of the atomizing upper seat 1111 away from the liquid storage chamber, and the base assembly 120 and the atomizing upper seat 1111 form an atomizing chamber. The atomizing chamber 1104 has an air inlet and an air outlet. The air inlet is used to introduce outside air into the atomizing chamber, and the air outlet is used to discharge the aerosol from the atomizing chamber. Specifically, the air inlet is connected to outside air, and the air outlet is connected to the air outlet channel. During the user's inhalation through the air outlet channel, outside air flows sequentially through the air outlet, the atomizing chamber, the air outlet, and the air outlet channel, and finally enters the user's mouth; the aerosol in the atomizing chamber enters the user's mouth with this airflow.

[0068] In other embodiments, the base assembly 120 includes an electrical connection structure 1203 and an atomizing lower seat 1204. The electrical connection structure 1203 may include at least one electrode post or elastic sheet, etc. The atomizing lower seat 1204 is provided with at least one fixing hole, which penetrates the bottom end of the atomizing lower seat. The electrical connection structure 1203 is disposed in the fixing hole, and the fixing hole is used to fix the electrical connection structure 1203. When the atomizer 10 and the power supply assembly are mated, the electrical connection structure 1203 can contact the power supply assembly and conduct electricity, thereby enabling the power supply assembly to supply power to the atomizer 10.

[0069] In some embodiments, a snap-fit ​​structure is also included, in which, in the first position, the base assembly 120 is fixedly connected to the atomizing assembly 110 via the snap-fit ​​structure.

[0070] In some embodiments, the base assembly 120 includes a bottom cover 1205, which is sleeved around the base assembly 120. Engaging structures are respectively disposed on the bottom cover 1205 and the housing 130.
