[0047] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Please also refer to Figures 1 to 6 In a first aspect, an embodiment of the present application provides an atomizer, wherein the atomizer 10 includes a housing assembly 11 , an atomizing assembly 12 and a bottom cover 13 .

[0049] Please also refer to Figures 7 to 9 In a second aspect of an embodiment of the present application, an aerosol generating device is provided. The aerosol generating device 100 includes a power supply assembly 20 and an atomizer 10 according to any one embodiment of the present application. The power supply assembly 20 is electrically connected to the atomizer 10.

[0050] The power supply assembly 20 is mainly used to supply power to the atomizer 10 and control operations such as opening or closing of the entire aerosol generating device 100. The atomizer 10 is mainly used to accommodate an aerosol generating matrix and atomize the aerosol generating matrix after being powered on.

[0051] Aerosol-generating substrates include, but are not limited to, materials used for medical, health, wellness, and beauty purposes. Examples include, but are not limited to, pharmaceuticals, nicotine-containing or nicotine-free materials, and the like. For example, aerosol-generating substrates may be solid or liquid materials primarily made from plants, such as tobacco, with appropriate aerosol formers and aroma materials added thereto.

[0052] In some embodiments, the atomizer 10 and the power supply assembly 20 can be mechanically and electrically connected axially. Furthermore, the atomizer 10 and the power supply assembly 20 can be connected together in a detachable manner, such as a magnetic connection, a threaded connection, or a snap connection. Both the atomizer 10 and the power supply assembly 20 can be replaced or upgraded independently, reducing replacement costs and saving users money. Of course, in other embodiments, the atomizer 10 and the power supply assembly 20 can also be connected together in a non-detachable manner.

[0053] It should be noted that the specific type of the aerosol generating device 100 provided in the embodiment of the present application is not limited. For example, the aerosol generating device 100 can be a medical atomization device, an air humidifier, or an atomization device such as an electronic cigarette.

[0054] The power supply assembly 20 includes a battery cell 21, a first terminal 22, and a second terminal 23. The battery cell 21 is a component of the power supply assembly 20 that stores electricity. One of the first terminal 22 and the second terminal 23 is a positive terminal, and the other is a negative terminal. The battery cell 21 outputs electrical energy through the first terminal 22 and the second terminal 23.

[0055] The housing assembly 11 is provided with a receiving cavity for receiving an aerosol generating substrate.

[0056] The atomizer assembly 12 is disposed within the housing assembly 11 and includes an atomizer core 121, a first conductive member 122, and a second conductive member 123. The atomizer core 121 is electrically connected to the external power supply assembly 20 via the first conductive member 122 and the second conductive member 123. For example, the first terminal 22 is electrically connected to the first conductive member 122, and the second terminal 23 is electrically connected to the bottom cover 13 or the second conductive member 123.

[0057] It should be noted that the “external” here refers to the aerosol generating device 100 , and the power supply assembly 20 is a part of the aerosol generating device 100 .

[0058] The atomizing core 121 is used to atomize the aerosol generating substrate to generate an aerosol. The method of atomizing the aerosol generating substrate by the atomizing core 121 is not limited. For example, it can be heating atomization, ultrasonic atomization, etc. In the embodiment where the atomizing core 121 atomizes the aerosol generating substrate by heating atomization, the type of the atomizing core 121 is also not limited. For example, it can be a heating needle, a heating net or a heating element. Figure 4 The power supply assembly 20 is used to supply electrical energy to the atomizing core 121, and the atomizing core 121 converts the electrical energy into thermal energy to heat the atomized aerosol generating substrate to generate aerosol.

[0059] The bottom cover 13 is provided at the bottom of the housing assembly 11. In the embodiment of the present application, the terms "top" and "bottom" need to be understood based on the height direction of the atomizer 10. The height direction of the atomizer 10 is as follows: Figure 1 shown.

[0060] The bottom cover 13 is provided with a first through-hole 13a, and the axis of the bottom cover 13 passes through the first through-hole 13a and the first conductive member 122. It is understood that when the atomizer 10 is assembled to the power assembly 20 at any angle along its circumference, the atomizer 10 is generally adjusted with the axis of the bottom cover 13 as the center of rotation. Therefore, regardless of the angle at which the atomizer 10 is assembled to the power assembly 20, the first conductive member 122 and the first terminal 22 of the power assembly 20 will maintain constant contact, thereby achieving electrical connection.

[0061] The second conductive member 123 is electrically connected to the bottom cover 13. The bottom cover 13 is made of a conductive material, such as metal. There is no electrical connection between the first conductive member 122 and the bottom cover 13.

[0062] The atomizer 10 is mounted on the power assembly 20 via the bottom cover 13. Therefore, when the atomizer 10 is mounted on the power assembly 20 at any angle along its circumference, the second terminal 23 of the power assembly 20 is always electrically connected to the bottom cover 13, and the second conductive member 123 is also electrically connected to the bottom cover 13. In other words, when the atomizer 10 is mounted on the power assembly 20 at any angle along its circumference, the second terminal 23 is always electrically connected to the second conductive member 123.

[0063] In the related art, the atomizer needs to be assembled with the power supply assembly in a specific direction to achieve circuit conduction between the atomizer assembly and the power supply assembly. The current commonly used solution is to implement a fool-proof design so that the atomizer can only be inserted into the power supply assembly in a set specific direction. This will result in a large user education cost and is inconvenient to use.

[0064] The atomizer of the embodiment of the present application is arranged on the power assembly 20 through the bottom cover 13. The bottom cover 13 is provided with a first through hole 13a. The atomizer assembly 12 includes a first conductive member 122 and a second conductive member 123. The axis of the bottom cover 13 passes through the first through hole 13a and the first conductive member 122. When the atomizer 10 is assembled to the power assembly 20 at any angle along its circumference, the atomizer 10 is roughly adjusted with the axis of the bottom cover 13 as the rotation center. Therefore, no matter which angle the atomizer 10 is at, When the atomizer 10 is assembled onto the power assembly 20 at any angle, the first conductive member 122 and the first terminal 22 of the power assembly 20 are in constant contact, thereby achieving electrical connection. At the same time, the bottom cover 13 is made of a conductive material. When the atomizer 10 is assembled onto the power assembly 20 at any angle along its circumference, the second terminal 23 of the power assembly 20 is also constantly electrically connected to the bottom cover 13, and the bottom cover 13 is in turn electrically connected to the second conductive member 123. That is, the second terminal 23 is also constantly electrically connected to the second conductive member 123. This facilitates the assembly of the atomizer 10 with the power assembly 20 from multiple directions and conducts electrical circuits between the atomizer assembly 12 and the power assembly 20, thus facilitating user use.

[0065] It should be noted that there is no limitation on the way the conductive member is electrically connected to the bottom cover 13. Figure 2 A second through hole 13 b is further defined on the bottom cover 13 . At least a portion of the second conductive member 123 is disposed in the second through hole 13 b and abuts against the wall of the second through hole 13 b .

[0066] The second via hole 13 b can produce a certain positioning effect on the second conductive member 123 , thereby facilitating improvement of the stability and reliability of the electrical connection between the second conductive member 123 and the second via hole 13 b .

[0067] The shape of the second via hole 13b is not limited. For example, it can be polygonal, elliptical, irregular or Figure 2 When the second via hole 13b is circular, the second conductive member 123 can be inserted into the second via hole 13b at any angle along its circumference, thereby facilitating the second conductive member 123 to be disposed in the second via hole 13b and to abut against the wall of the second via hole 13b.

[0068] In some other embodiments, the second via hole 13 b may not be provided on the bottom cover 13 , that is, the second conductive member 123 is directly attached to the wall of the bottom cover 13 .

[0069] In one embodiment, please refer to Figures 3 to 5 A flange 131 is formed on one side of the bottom cover 13 along the height direction of the atomizer 10 , and the area surrounded by the flange 131 constitutes part of the second through hole 13b.

[0070] In this embodiment, the flange 131 is provided to extend the length of the second via hole 13b, thereby increasing the contact area between the second conductive member 123 and the wall of the second via hole 13b, thereby improving the stability of the second conductive member 123 abutting in the second via hole 13b.

[0071] It should be noted that the flange 131 may be formed on the side of the bottom cover 13 away from the atomizer core 121; Figure 4 As shown, the flange 131 may also be formed on the side of the bottom cover 13 facing the atomizer core 121 .

[0072] It is understandable that the flange 131 is formed on the side of the bottom cover 13 facing the atomizer core 121. During the assembly of the atomizer 10 with the power supply assembly 20, the flange 131 will not squeeze the power supply assembly 20, which is conducive to the assembly of the atomizer 10 and the power supply assembly 20.

[0073] In one embodiment, please refer to Figure 3 、 Figure 4 and Figure 6 The bottom cover 13 is provided with a reinforcement portion 13 c, and a portion of a side wall of the bottom cover 13 along the height direction of the atomizer 10 is recessed to form the reinforcement portion 13 c.

[0074] Since the bottom cover 13 is located at the bottom of the atomizer 10, it requires a certain load-bearing capacity. In this embodiment, by providing a reinforcement portion 13c on the bottom cover 13, the bottom cover 13 has a higher structural strength and a greater load-bearing capacity. As a result, the bottom cover 13 has better overall stability, which helps improve the reliability of the atomizer 10.

[0075] It should be noted that the side of the bottom cover 13 facing the atomizer core 121 may be recessed to form a reinforcement portion 13c; Figure 4 As shown, the side of the bottom cover 13 facing away from the atomizer core 121 may be recessed to form a reinforcement portion 13c.

[0076] It is understandable that the side of the bottom cover 13 facing away from the atomizer core 121 is recessed to form the reinforcement portion 13c. The reinforcement portion 13c does not protrude from the side of the bottom cover 13 facing the power assembly 20. During the assembly of the atomizer 10 with the power assembly 20, the reinforcement portion 13c will not squeeze the power assembly 20, which is conducive to the assembly of the atomizer 10 and the power assembly 20.

[0077] In other embodiments, the bottom cover 13 may be provided with some reinforcing ribs to enhance the structural strength, and the reinforcing ribs may be understood as the reinforcing portion 13 c of the bottom cover 13 .

[0078] In one embodiment, please refer to Figures 3 to 5 A mounting groove 13m is provided on one side of the bottom cover 13 facing the atomizer core 121 .

[0079] In other words, the bottom cover 13 is not a plate-like structure as a whole, but is roughly a groove-like structure, thereby improving the overall structural strength of the bottom cover 13.

[0080] At least a portion of the housing assembly 11 extends into the mounting groove 13m. During the assembly of the housing assembly 11 and the bottom cover 13, the mounting groove 13m also facilitates positioning between the housing assembly 11 and the bottom cover 13, thereby facilitating assembly of the two and improving assembly efficiency.

[0081] In one embodiment, please refer to Figures 3 to 5 The outer diameter of the housing assembly 11 at one end close to the bottom cover 13 is reduced to form a step structure 111, and at least a portion of the step structure 111 is disposed in the mounting groove 13m.

[0082] After the housing assembly 11 and the bottom cover 13 are assembled, the atomizer 10 as a whole has a minimal step difference at the connection between the housing assembly 11 and the bottom cover 13, which provides a better grip for the user and enhances the user experience. Furthermore, the minimal step difference at the connection between the bottom cover 13 and the housing assembly 11 also enhances the aesthetics of the atomizer 10.

[0083] In one embodiment, please refer to Figure 1 、 Figure 5 and Figure 6 A first clamping portion 111 a is provided on the outer wall of the housing assembly 11 , and a second clamping portion 13 n is provided on the bottom cover 13 . The first clamping portion 111 a and the second clamping portion 13 n are clamped together.

[0084] Specifically, if Figure 5 As shown, the first clamping portion 111 a is provided on the step structure 111 .

[0085] Exemplarily, one of the first clamping portion 111 a and the second clamping portion 13 n is a clamping protrusion, and the other side is a clamping slot, and the clamping protrusion is clamped into the clamping slot.

[0086] During the assembly process of the bottom cover 13 and the shell assembly 11, it is only necessary to operate the atomizer 10 and the shell assembly 11 and bring the two close to each other along the height direction of the atomizer 10. The snap-fit ​​protrusion will be slightly deformed and then snapped into the snap-fit ​​groove, thereby completing the assembly of the bottom cover 13 and the shell assembly 11. This structure makes the assembly between the bottom cover 13 and the shell assembly 11 more convenient.

[0087] In other embodiments, the bottom cover 13 and the housing assembly 11 may also be connected by fastening with fasteners, plugging, riveting, or other connection methods.

[0088] In one embodiment, please refer to Figure 2 、 Figure 4and Figure 9 At least a portion of the first conductive member 122 is disposed in the first via hole 13 a and is spaced apart from the hole wall of the first via hole 13 a.

[0089] Thus, the first terminal 22 is easily electrically connected to the first conductive member 122 , and air insulation is achieved between the first conductive member 122 and the bottom cover 13 , thereby effectively preventing the battery cell 21 from short-circuiting.

[0090] In some other embodiments, one of the first conductive member 122 and the power supply assembly 20 is electrically connected to the other through the first via 13 a.

[0091] For example, one end of the first conductive member 122 does not extend into the first via hole 13 a , and the first terminal 22 of the power supply assembly 20 needs to pass through the first via hole 13 a to achieve electrical connection with the first conductive member 122 .

[0092] For another example, if one end of the first conductive member 122 passes through the first through hole 13 a , the first terminal 22 of the power supply assembly 20 can be electrically connected to the first conductive member 122 without extending into the first through hole 13 a .

[0093] In one embodiment, the bottom cover 13 is projected onto a plane perpendicular to the axis of the bottom cover 13, and the projection is symmetrical. This makes the overall structure of the bottom cover 13 more regular, which facilitates the insertion of the atomizer 10 into the power supply assembly 20 at multiple angles along its circumference, making it easier for users to use.

[0094] It should be noted that the specific shape of the projection of the bottom cover 13 is not limited, and can be, for example, a relatively regular shape such as a circle or a regular polygon.

[0095] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 9 The cross section of the shell assembly 11 is a regular polygon or a circle, wherein the cross section of the shell assembly 11 is perpendicular to the height direction of the atomizer 10 .

[0096] The shell assembly 11 is generally axially symmetrical in structure, and has similar external shapes when the shell assembly 11 is in a plurality of different torsion angles along the circumference of the atomizer 10 . This facilitates assembly of the atomizer 10 with the power supply assembly 20 at a plurality of torsion angles along its circumference.

[0097] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 9 , the perpendicular midline of the cross section of the housing assembly 11 passes through the first conductive member 122; or,

[0098] The projection of the first conductive member 122 on the cross section of the housing assembly 11 covers the center point of the cross section of the housing assembly 11 , wherein the projection direction of the first conductive member 122 is parallel to the height direction of the atomizer 10 .

[0099] Therefore, when the atomizer 10 rotates along its circumferential direction, the relative position of the first conductive member 122 will not change substantially, and the first conductive member 122 can be constantly electrically connected to the first terminal 22 , thereby facilitating the conduction of the circuit between the atomizer core 121 and the battery core 21 .

[0100] In one embodiment, please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 9 The cross-section of the shell component 11 is a regular polygon or a circle, the cross-section of the power supply component 20 is the same as the cross-section of the shell component 11, and the cross-sections of the shell component 11 and the power supply component 20 are both perpendicular to the height direction of the aerosol generating device 100.

[0101] It should be noted that the height direction of the aerosol generating device 100 is parallel to the height direction of the atomizer 10 .

[0102] The second terminal 23 contacts any position of the bottom cover 13 to supply power to the atomizer core 121. Thus, after the atomizer 10 is assembled with the power supply assembly 20 at any angle along its circumference, the battery core 21 can also be electrically connected to the atomizer core 121.

[0103] In this embodiment, the power supply assembly 20 and the shell assembly 11 are both axially symmetrical structures. The two can be assembled at multiple angles along the circumference of the aerosol generating device 100, and the overall appearance and external structure of the aerosol generating device 100 will basically not change, which is conducive to improving the user experience.

[0104] In one embodiment, please refer to Figure 8 and Figure 9 The aerosol generating device 100 includes a housing 30 , which is disposed around the outer periphery of the bottom cover 13 .

[0105] It should be noted that the housing 30 is not necessarily located on the outer surface of the aerosol generating device 100 , but is only located on the outer periphery of the bottom cover 13 relative to the bottom cover 13 .

[0106] It is understood that after the atomizer 10 and the power supply assembly 20 are assembled, the second terminal 23 is electrically connected to the bottom cover 13, and the bottom cover 13 may become electrically charged. Exposing the bottom cover 13 directly to the exterior of the aerosol generating device 100 presents a safety risk. Therefore, the housing 30 can be used to isolate the conductive path between the bottom cover 13 and the exterior of the aerosol generating device 100, thereby improving the safety of the aerosol generating device 100.

[0107] The specific manner in which the housing 30 separates the conductive path between the bottom cover 13 and the outside of the aerosol generating device 100 is not limited. Figure 9 In the radial direction of the bottom cover 13 , there is a gap between the inner wall of the housing 30 and the outer wall of the bottom cover 13 . Thus, air insulation is formed between the bottom cover 13 and the housing 30 .

[0108] In other embodiments, the housing 30 may also be made of insulating material.
