Detailed Embodiments

[0026] The present utility model will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many details are described to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid overwhelming the core part of the present application with excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0027] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated that a certain sequence must be followed.

[0028] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0029] Please refer to Figures 1 to 7 , an atomization device 1 is provided in an embodiment of the present application, which includes a housing assembly 2 and a metal housing 4.

[0030] Among them, an accommodation cavity is formed inside the housing assembly 2. The housing assembly 2 is provided with an exposed installation groove 20 for the atomizer 3 to be inserted. An installation position 23 is provided on the outer surface of the housing assembly 2. The installation groove 20 provided in the housing assembly 2 is used to accommodate the atomizer 3. The accommodation cavity can be interconnected chambers, or at least some of the chambers are isolated from other chambers, or some small chambers are embedded in a large chamber. The embodiments of the present application do not limit it.

[0031] In order to improve the surface strength of the atomization device 1 and enhance the connection stability of the housing assembly 2, the atomization device 1 includes a metal housing 4, which is wrapped around the outside of the housing assembly 2, and the metal housing 4 is fixedly connected to the housing assembly 2; a window 45 corresponding to the installation position 23 is provided on the metal housing 4. The metal housing 4 is located on the outermost layer of the entire atomization device 1, so the part of the metal housing 4 is the first to be contacted by the user during use. Due to the material of the metal housing 4, the metal housing 4 usually has a higher hardness than the plastic housing assembly 2, which can effectively prevent other external components from scratching; and the metal housing 4 has higher toughness, and its drop resistance performance is greatly enhanced. By providing the window 45 on the metal housing 4, the light-impermeable characteristic of the metal material can be avoided from affecting the content display at the covered part of the metal housing 4.

[0032] In addition, the metal housing 4 also covers at least part of the buckle assembly 24, which avoids the exposure of at least part of the buckle assembly 24, thereby reducing the risk of the buckle assembly 24 being directly disassembled. Of course, the metal housing 4 can cover all the buckle assemblies 24, which can effectively improve the integrity of the entire atomization device 1.

[0033] Since various components need to be installed inside the atomization device 1, the housing assembly 2 can be made of plastic material. Utilizing the easy-to-form characteristic of the plastic material, a structure with a specific shape can be formed through processes such as injection molding; in the embodiment of the present application, the plastic housing assembly 2 is used in combination with the metal housing 4 to form the housing of the atomization device 1. Since the plastic housing assembly 2 made of plastic material is easy to form the required shape of the atomization device 1, and the metal housing 4 covering the outside of the housing assembly 2 can improve the surface strength, the atomization device 1 in the embodiment of the present application takes into account the easy-to-process characteristic of the plastic housing assembly 2 made of plastic material and the high strength and high toughness characteristics of the metal housing 4. Moreover, using the housing assembly 2 as a lining can effectively reduce the amount of metal material required for the metal housing 4, thereby saving the production cost of the product.

[0034] In some alternative embodiments, please refer to Figure 3, in order to enhance the appearance texture, especially to distinguish different display contents on the surface of the metal shell 4, the outer surface of the metal shell 4 includes a polished surface area 43 and a laser frosted surface area 44. Among them, the polished surface area 43 is used to display identification information, and the polished surface area 43 is surrounded by the laser frosted surface area 44. For example, the laser frosted surface area 44 can cover other areas of the outer surface of the metal shell 4 except the polished surface area 43. Among them, a bright logo can be set on the atomized surface of the metal shell 4. The specific manufacturing process can be to first polish the entire surface of the metal shell 4 through a surface treatment process to form a bright surface, and then use a machine carving laser process to form a frosted surface in places other than the logo. Compared with the exposure and development process, the yield is higher and the price is lower; then, the surface of the metal shell 4 is divided into a polished surface area 43 and a laser frosted surface area 44 by the process. Among them, the polished surface area 43 is used to display logo and other identification information, and the laser frosted surface area 44 covers other areas of the metal shell 4.

[0035] In some alternative embodiments, the material of the metal shell 4 can be aluminum alloy. Aluminum alloy has the characteristics of high hardness and low density, which can improve the surface strength of the atomizing device 1 while reducing the weight of the atomizing device 1 and ensuring the user experience.

[0036] In some alternative embodiments, in order to simplify the manufacturing process and reduce the process complexity between the housing assembly 2 and the metal shell 4, the housing assembly 2 can specifically include a front shell 21 and a rear shell 22. The front shell 21 and the rear shell 22 are fixedly connected by at least two snap components 24; the metal shell 4 includes a metal front shell 41 and a metal rear shell 42. The metal front shell 41 is fixedly arranged on the outer surface of the front shell 21, and the metal rear shell 42 is fixedly arranged on the outer surface of the rear shell 22. Compared with integrally forming the entire metal shell 4, distinguishing the metal shell 4 into a front and a rear, that is, a metal front shell 41 and a metal rear shell 42, can reduce the process difficulty and improve the product yield. In addition, the fixed connection method between the metal shell 4 and the housing assembly 2 can generally be adhesive connection, that is, the metal shell 4 can be adhesively fixed to the outside of the housing assembly 2. In the embodiment of the present application, the housing assembly 2 includes a front shell 21 and a rear shell 22.

[0037] In some alternative embodiments, the metal shell 4 can also be integrally formed with the housing assembly 4, and the integral forming method can be two-color molding or the like.

[0038] In some alternative embodiments, please refer to Figure 4, To achieve the screen display effect, the atomizing device further includes a display 7; the installation position 23 includes a display screen installation position 231 for installing the display 7; the atomizing device further includes a light-transmitting cover plate 8, the light-transmitting cover plate 8 is fixedly connected to the housing assembly 2, and the light-transmitting cover plate 8 cooperates with the display screen installation position 23 to enclose the display 7 therein. Based on the increasing requirements for the function implementation of the atomizing device 1, it has gradually become a necessary means to display the usage state of the atomizing device 1 for the user. Among them, the display 7 can be used to display status information such as the remaining power, working temperature, and aerosol matrix remaining amount of the atomizing device 1, and can also display environmental information including but not limited to time, weather, etc. The display screen installation position 231 can be specifically formed on the outer surface of the front shell 21 for embedding the display 7 therein; in order to prevent the display 7 from falling off, the display 7 can be fixed by means such as glue, or an additional light-transmitting cover plate 8 can be provided outside the display 7 to protect the display 7 and prevent the display 7 from being scratched.

[0039] In some alternative embodiments, to achieve the fixed connection between the front shell 21 and the rear shell 22, the buckle assembly 24 can specifically include at least two pairs of buckles 241 and slots 242 arranged in pairs. The buckles 241 are respectively arranged on the front shell 21 and the rear shell 22, and the slots 242 are correspondingly arranged on the rear shell 22 and the front shell 21 respectively; the front shell 21 and the rear shell 22 are fixedly connected through the cooperation between the buckles 241 and the slots 242. That is to say, in the embodiments of the present application, by respectively arranging the combination of the buckles 241 and the slots 242 on the front shell 21 and the rear shell 22, the fixed connection between the front shell 21 and the rear shell 22 can be tightened from the two components of the front shell 21 and the rear shell 22 respectively, thereby improving the assembly stability between the front shell 21 and the rear shell 22. Specifically, in the embodiments of the present application, please refer to Figures 3 to 5, at least one buckle 241 is provided on the front shell 21, and the buckle 241 extends from the edge area of the front shell 21 in the direction of the rear shell 22; at least one slot 242 is also provided on the front shell 21, and the slot 242 is provided in the edge area of the front shell 21, and the setting position and quantity of the slot 242 correspond to the buckle 241 provided on the rear shell 22; at least one buckle 241 is provided on the rear shell 22, and the buckle 241 extends from the edge area of the rear shell 22 in the direction of the front shell 21; at least one slot 242 is also provided on the rear shell 22, and the slot 242 is provided in the edge area of the rear shell 22, and the setting position and quantity of the slot 242 correspond to the buckle 241 provided on the front shell 21; the front shell 21 and the rear shell 22 are fixedly connected respectively through the cooperation between the buckle 241 provided on the front shell 21 and the slot 242 provided on the rear shell 22, and the cooperation between the slot 242 provided on the front shell 21 and the buckle 241 provided on the rear shell 22. That is to say, in the embodiment of the present application, the front shell 21 and the rear shell 22 are fixedly connected through the buckle assembly 24, and the buckle and slot respectively provided on two components need to cooperate with each other for the buckle connection. In the embodiment of the present application, there are two types of buckle cooperation, which are respectively a cooperation formed between the buckle 241 provided on the front shell 21 and the slot 242 provided on the rear shell 22, and a cooperation formed between the buckle 241 provided on the rear shell 22 and the slot 242 provided on the front shell 21. Since the connection methods of the two buckle assemblies 24 are opposite, for the buckle 241, it exerts a pulling force in the direction of the front shell 21 on the slot 242, and for the buckle 241, it exerts a pulling force in the direction of the rear shell 22 on the slot 242. The two pulling forces are in opposite directions. Therefore, if one type of buckle cooperation is disassembled, it will instead increase the pulling force of the other buckle, thus greatly reducing the disassembly difficulty between the front shell 21 and the rear shell 22 and increasing the connection strength between the front shell 21 and the rear shell 22.

[0040] In some alternative embodiments, the specific structure of the buckle 241 may include: for the front shell 21, the buckle 241 includes an elastic arm 213 extending from the front shell 21 to the rear shell 22, and a claw 214 provided at the end of the elastic arm 213. The elastic arm 213, the claw 214 and the front shell 21 are integrally formed. The elastic arm 213 itself has a certain elasticity. Within the allowable range of elastic deformation, it can enter the slot along the outside of the slot driven by the claw 214. During the process of entering the slot, the elastic arm 213 undergoes elastic deformation and has a tendency to return to its original shape; after entering the slot, the claw 214 is clamped in the slot, and the elastic arm 213 returns to the state before elastic deformation, so that a locking connection is formed between the claw 214 and the slot, thereby realizing fixed connection.

[0041] Of course, in addition to the buckle 241 provided on the front shell 21, the structure of the buckle 241 provided on the rear shell 2 is similar; for the rear shell 22, the buckle 241 includes an elastic arm 213 extending forward from the rear shell 22 to the front shell 21, and a claw 214 provided at the end of the elastic arm 213. The elastic arm 213, the claw 214 and the rear shell 22 are integrally formed.

[0042] In some alternative embodiments, in order to further improve the connection strength, please refer to Figure 4 and Figure 5 ., the claw 214 of the buckle 241 extends away from the central region of the front shell 21; the corresponding card slot 242 includes a through slot, and the claw 214 passes through the through slot and is buckled to the end face of the through slot to realize the cooperation between the buckle 241 and the card slot 242. That is to say, the buckle 241 cooperates with the card slot from the inside to realize the clamping connection. The corresponding card slot 242 is a through slot. After the claw 214 in the buckle 241 passes through the through slot, it is buckled to the end face at the bottom of the through slot to realize the clamping connection. Since the claw 214 passes through the through slot in this connection method, compared with the buckle buckled from the outside, the difficulty of removing the claw 214 from the through slot is greatly increased, thereby further improving the connection strength between the front shell 21 and the rear shell 22.

[0043] In some alternative embodiments, in order to further enhance the connection strength between the front shell 21 and the rear shell 22, the buckle 241 and the corresponding card slot 242 include at least two, and each buckle 241 is at least distributed in at least two side edge regions of the front shell 21; and / or, the buckle 241 and the corresponding card slot 242 include at least two, and each buckle 241 is at least distributed in at least two side edge regions of the rear shell 22. In other words, the buckle 241 can be distributed on different sides of the front shell 21, adjacent sides on the front shell 21, or opposite sides on the front shell 21, or even each side of the front shell 21. Each time a set of buckles 241 is provided in the different side edge regions, the connection strength between the front shell 21 and the rear shell 22 will be improved accordingly. The same is true for the buckle 241, and the buckles 241 can also be staggered to form an interlocking connection structure.

[0044] In some alternative embodiments, please refer to Figures 5 - 7, to operate the atomization device 1 and control the working power of the heating core 33, physical buttons are usually used for operation; generally, two operations of increasing and decreasing need to be set for the physical buttons. To avoid button adhesion, a button assembly 5 is further provided on the atomization device 1. The button assembly 5 includes a base 51, a circuit board 52, and a button 53; the installation position 23 further includes an installation component installation position 232. The base 51 is formed in the button assembly installation position 232 of the housing assembly 2, and the circuit board 52 is fixedly arranged in the accommodation cavity; on both sides of the base 51 along the length direction, paired first rotating parts 511 are provided; on both sides of the button 53 along the length direction, second rotating parts 531 are provided. The second rotating parts 531 extend from the position where the button 53 is located towards the base 51, and the first rotating parts 511 cooperate with the second rotating parts 531 to achieve the rotational connection between the button 53 and the base 51. In the embodiment of the present application, a lever-type button is adopted to avoid the adhesion of the button 53. A rotational connection is formed between the button 53 and the base 51 through the first rotating parts 511 and the second rotating parts 531. When one end of the button 53 moves towards the base 51 to trigger the button function, the other end moves away from the base 51. Therefore, only the button function at one end is triggered, effectively avoiding the adhesion of the button 53.

[0045] In some alternative embodiments, to further prevent the adhesion of the button 53, the button 53 further includes a protrusion 532. The protrusion 532 is arranged between the second rotating parts 531 and extends towards the base 51. In this structure, the protrusion 532 is equivalent to adding a fulcrum of the lever. Even if the position of the button 53 is offset, the position can be limited by the protrusion 532, avoiding the situation where the other end is also triggered when one end of the button 53 is triggered.

[0046] In some alternative embodiments, to facilitate the assembly of the second rotating part 531 and the first rotating part 511, the specific structure of the second rotating part 531 may include a connecting elastic piece 533 and a rotating convex block 534. The connecting elastic piece 533 extends from the two side edges of the button 53 along the length direction towards the base 51; the rotating convex block 534 is arranged at the end of the connecting elastic piece 533. The rotating convex block 534 extends along the direction away from the center of the button 53, and the thickness of the rotating convex block 534 gradually decreases along the extending direction of the connecting elastic piece 533; the first rotating part 511 includes a groove matching the rotating convex block 534. The second rotating part 531 can be snap-fitted into the first rotating part 511. The connecting elastic piece 533 in the second rotating part 531 is used to raise the position of the button, avoiding the rotation axis between the button and the base 51 being too short; and the connecting elastic piece 533 cooperates with the wedge-shaped rotating convex block 534, enabling the rotating convex block 534 to be conveniently inserted into the groove of the first rotating part 511, greatly reducing the assembly difficulty.

[0047] An embodiment of the present application provides an atomization device 1. By arranging a metal shell 4 outside the shell assembly 2, the structural strength of the outer surface of the atomization device 1 is effectively improved, and the risk of scratching is reduced. Moreover, other easily processable materials can be used inside the metal shell 4 to form the shell assembly 2, thereby reducing the processing difficulty of the shell of the atomization device 1 and further reducing the processing cost.

[0048] An embodiment of the present application also provides an atomization device. Please continue to refer to Figures 1 to 7 , and the atomization device includes an atomizer 3, a power supply assembly 6, and the above-mentioned atomization device 1.

[0049] Among them, the atomizer 3 is detachably installed in the installation groove 20. The atomizer 3 includes an air inlet 31 and an air outlet 32 arranged opposite to each other. The air inlet 31 is located in the installation groove 20, and the air outlet 32 is located outside the installation groove 20. A heating core 33 and an aerosol matrix 34 are arranged in the atomizer 3. The heating core 33 is used to heat the aerosol matrix 34 to form an aerosol, and the aerosol is discharged from the air outlet 32. The function of the atomizer 3 is to heat the aerosol matrix 34 to generate an aerosol. The atomizer 3 can be fixedly installed or detachably installed in the installation groove 20. The aerosol matrix 34 can be pre-stored in the atomizer 3. The specific carriers can include structures such as a liquid storage cotton and a liquid storage ceramic, or directly stored through a liquid storage cavity. The heating core 33 starts the heating operation on the aerosol matrix 34 according to the start signal and discharges the generated aerosol from the air outlet 32.

[0050] In some embodiments, the power supply assembly 6 can be arranged in the accommodation cavity formed by the front shell 21 and the rear shell 22. The power supply assembly 6 can be arranged in the shell assembly 2 and on one side in the radial direction of the installation groove 20, and is used to supply electric energy to the atomizer 3 and the display 7 in the atomization device. The atomizer 3 is used to heat the aerosol matrix 34 into an aerosol. The power supply assembly 6 and the atomization device 1 can be fixedly connected or detachably connected. When the atomization device 1 and the power supply assembly 6 are detachably connected, the atomization device 1 and the power supply assembly 6 can be replaced according to the usage situation. The above-mentioned atomization device is only one embodiment of the present application, and the specific structure inside the atomization device will not be elaborated further.
