[0036] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may 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. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0037] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0038] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0039] With the continuous improvement of aerosol generating devices, higher requirements are also put forward for the assembly of the aerosol generating component 600 and the shell. For example, some aerosol generating components 600 have special components such as an approximately L-shaped curved display screen 610 on the side. The usual assembly method of installing from the top or bottom of the shell is not conducive to the lossless assembly of the aerosol generating component 600, and it is difficult to adapt to the assembly requirements of some new aerosol generating components 600.

[0040] In the embodiment of the present application, the structure of the first shell 100 and the second shell 200 is adopted, so that the aerosol generating component 600 can be assembled from the side, which helps to meet the assembly requirements of the aerosol generating component 600, and by providing the first guide structure 310 and the second guide structure 320, precise positioning can be achieved during lateral assembly without the assistance of tooling and fixtures, which helps to overcome the problems of difficult alignment and assembly in lateral assembly, simplify the assembly process, and improve assembly efficiency.

[0041] In one embodiment, a housing assembly of an aerosol generating device is disclosed. Figures 1-6 The housing assembly includes a first housing 100 , a second housing 200 and a connecting structure 400 for connecting the first housing 100 and the second housing 200 .

[0042] In order to describe the housing assembly of the aerosol generating device more clearly and in detail, three mutually perpendicular directions are defined herein based on the structural construction of the housing assembly of the aerosol generating device, namely: a first direction, a second direction and a third direction. Figure 1 , the direction in which the housing assembly has a nozzle setting position can be taken as the first direction, that is, the housing assembly has a nozzle setting position at one end of the first direction, and the so-called nozzle setting position refers to the position on the housing assembly for setting the nozzle member 500. The nozzle member 500 can be integrally provided on the housing assembly or assembled on the housing assembly. For example, the first direction refers to Figure 1The up and down directions of the housing assembly shown in Figure 1 The left and right directions and the third direction of the housing assembly shown in Figure 1 The front-to-back direction of the housing assembly is shown in .

[0043] In one embodiment, please refer to Figure 1-Figure 3 The first shell 100 has a first shell first side surface 110 located on one side of the shell assembly in the second direction, and a first shell second side surface 120 located on one side of the shell assembly in the third direction. The second shell 200 has a second shell first side surface 210 located on the other side of the shell assembly in the second direction, and a second shell second side surface 220 located on one side of the shell assembly in the third direction. After the first shell 100 and the second shell 200 are assembled into a whole, they can be enclosed to form an installation cavity for the aerosol generating assembly 600. The first shell 100 and the second shell 200 are both open in the second direction, which facilitates the installation of the aerosol generating assembly 600 from the side.

[0044] For example, please refer to Figure 1-Figure 3 The first side surface 110 of the first shell and the second side surface 120 of the first shell are integrally provided, and the connection between the first side surface 110 and the second side surface 120 of the first shell is smooth, so that the first side surface 110 and the second side surface 120 of the first shell can form a first shell 100 structure with an approximately L-shaped cross section. The first side surface 210 of the second shell and the second side surface 220 of the second shell are also integrally provided, and the connection between the first side surface 210 and the second side surface 220 of the second shell is smooth, so that the first side surface 210 and the second side surface 220 of the second shell can form a second shell 200 structure with an approximately L-shaped cross section. When the first shell 100 and the second shell 200 are assembled, they are assembled with each other, and a mounting cavity for accommodating the aerosol generating assembly 600 is enclosed between the first side surface 110 of the first shell, the second side surface 120 of the first shell, the first side surface 210 of the second shell, and the second side surface 220 of the second shell. When assembling the aerosol generating device, the aerosol generating assembly 600 can be first installed on the first shell 100, and then the second shell 200 is moved close to and installed on the first shell 100 along the second direction, so that the aerosol generating assembly 600 is surrounded by the installation cavity.

[0045] Although the open arrangement of the first shell 100 and the second shell 200 in the second direction enables the aerosol generating assembly 600 to be installed from the side, the side assembly has problems such as difficulty in alignment and difficulty in assembly. Figure 1-Figure 3The housing assembly further includes a guide structure 300, which includes a first guide structure 310 and a second guide structure 320 that are cooperatively arranged. The first guide structure 310 and the second guide structure 320 are respectively arranged on one of the first housing 100 and the second housing 200, so that when the second housing 200 is assembled, it can be guided by the first guide structure 310 and the second guide structure 320 in a second direction close to the first housing 100, thereby forming an installation cavity for the aerosol generating assembly 600. The cooperative arrangement of the first guide structure 310 and the second guide structure 320 allows the first housing 100 and the second housing 200 to be precisely positioned during assembly without the aid of tooling, helping to overcome the problems of difficult alignment and assembly during lateral assembly, and also simplifying the assembly process and improving assembly efficiency.

[0046] In order to facilitate accurate alignment of the first housing 100 and the second housing 200 during assembly, in one embodiment, please refer to Figure 1-Figure 3 At least one set of guide structures 300 is respectively provided at both ends of the first shell 100 and the second shell 200 in the first direction.

[0047] For example, please refer to Figure 1-Figure 3 The guide structures 300 can be arranged in four groups on the inner walls of the first shell 100 and the second shell 200, wherein two groups can be respectively arranged at both ends of the first shell 100 and the second shell 200 in the first direction. The specific arrangement positions of the first guide structures 310 and the second guide structures 320 on the first shell 100 and the second shell 200 can be flexibly matched as needed to ensure that the first guide structures 310 and the second guide structures 320 can be arranged in a coordinated manner. Of course, in other embodiments, the guide structures 300 can also be arranged in two, three, five, or other numbers to meet design and usage requirements.

[0048] In some embodiments, please refer to Figure 1-Figure 3 The first guide structure 310 is a slide rail, and the second guide structure 320 is a guide protrusion. The slide rail has a slot 311 for the guide protrusion to be inserted along the second direction. The provision of the slide rail and the guide protrusion can not only achieve a guiding function, but also strengthen the structural strength of the first shell 100 and the second shell 200, and also make it difficult for the first shell 100 and the second shell 200 to separate when accidentally dropped during use, thereby improving the safety of the shell assembly. In other embodiments, the guide structure 300 can also be configured as follows: the first guide structure 310 is a guide protrusion, and the second guide structure 320 is a slide rail; it can also be configured as follows: the first guide structure 310 and the second guide structure 320 are respectively one of a slide groove and a guide protrusion; it can also be configured as other cooperating structures with a guiding function that can meet the guidance requirements along the second direction.

[0049] In one embodiment, please refer to Figure 2 and Figure 4 The first housing 100 includes a first-housing third side surface 130 disposed opposite the first-housing second side surface 120 in the third direction. When the second housing 200 is mounted on the first housing 100, the second-housing second side surface 220 covers the side of the first-housing third side surface 130 away from the first-housing second side surface 120. When the second housing 200 is assembled with the first housing 100, the second-housing second side surface 220 and the first-housing third side surface 130 can be first aligned, and then the second housing 200 can be moved in the second direction. The first-housing third side surface 130 and the second-housing second side surface 220 cooperate to provide a pre-guiding function, facilitating the mating of the first guide structure 310 and the second guide structure 320.

[0050] For example, please refer to Figure 2 The third side surface 130 of the first shell and the second side surface 120 of the first shell are respectively arranged on both sides of the first side surface 110 of the first shell in the third direction, and the third side surface 130 of the first shell is integrally arranged with the first side surface 110 of the first shell, so that the first side surface 110 of the first shell, the second side surface 120 of the first shell and the third side surface 130 of the first shell are jointly enclosed to form an installation area with an opening on one side in the second direction, so that the aerosol generating assembly 600 can be pre-installed in the installation area of the first shell 100 during assembly.

[0051] For some examples, please refer to Figure 2-Figure 4 The wall thickness of the third side surface 130 of the first shell can be set to be smaller than the wall thickness of the first side surface 110 of the first shell, and the third side surface 130 of the first shell can be set on a side of the first side surface 110 of the first shell close to the installation area, so that a step surface is formed between the first side surface 110 of the first shell and the third side surface 130 of the first shell, so that the second side surface 220 of the second shell can be fitted into the step surface. Furthermore, the sum of the wall thickness of the third side surface 130 of the first shell and the wall thickness of the second side surface 220 of the second shell can be set to be equal to or similar to the wall thickness of the first side surface 110 of the first shell, so that when the second side surface 220 of the second shell covers the third side surface 130 of the first shell, the outer wall surface of the interface between the second side surface 220 of the second shell and the first side surface 110 of the first shell is flush, thereby improving the grip feel.

[0052] Although setting the sum of the wall thickness of the third side surface 130 of the first shell and the wall thickness of the second side surface 220 of the second shell to be equal to the wall thickness of the first side surface 110 of the first shell can theoretically make the outer wall surface at the interface between the second side surface 220 of the second shell and the first side surface 110 of the first shell flush, due to the existence of processing tolerances in actual processing, there is still a height difference between the outer wall surface at the interface between the second side surface 220 of the second shell and the first side surface 110 of the first shell, that is, there is a step.

[0053] In this regard, in one embodiment, please refer to Figure 2 A step adjustment protrusion 131 is provided on the side of the third side 130 of the first shell facing away from the second side 120 of the first shell. This protrusion 131 is located on the side of the third side 130 of the first shell near the first side 110 of the first shell and is configured to abut against the second side 220 of the second shell to ensure that the outer surfaces of the second side 220 and the first side 110 of the first shell are flush. During production, the thickness of the step adjustment protrusion 131 can be adjusted based on the step difference at the interface between the second side 220 of the second shell and the first side 110 of the first shell to compensate for manufacturing tolerances.

[0054] For example, please refer to Figure 2 A plurality of step-adjusting protrusions 131 can be arranged at intervals along the first direction, and the end of the step-adjusting protrusion 131 away from the first side surface 110 of the first shell can be set as a wedge surface to guide the second side surface 220 of the second shell during assembly, which helps to avoid obstruction when the second side surface 220 of the second shell slides to the position of the step-adjusting protrusion 131.

[0055] In one embodiment, please refer to Figure 2 and Figure 3 An alignment protrusion 121 is provided on the side of the first housing second side 120 facing away from the first housing first side 110, and an alignment groove 211 is provided on the second housing first side 210 for at least partially inserting the alignment protrusion 121. Inserting the limiting protrusion 212 into the alignment groove 211 facilitates alignment between the first housing second side 120 and the second housing first side 210, improving the smoothness of the assembly joint.

[0056] For example, please refer to Figure 2 and Figure 3 The alignment protrusion 121 is arranged on the inner side of the second side surface 120 of the first shell, that is, the side of the second side surface 120 of the first shell close to the installation area, and the alignment groove 211 is arranged on the inner side of the first side surface 210 of the second shell. After the first shell 100 and the second shell 200 are assembled, the alignment protrusion 121 is snapped into the alignment groove 211 to limit the relative position of the joint between the second side surface 120 of the first shell and the first side surface 210 of the second shell, so as to prevent the outer wall surface of the first shell 100 from protruding from the outer wall surface of the second shell 200.

[0057] Furthermore, in order to prevent the second side surface 120 of the first shell from being pressed from the outside at the joint with the first side surface 210 of the second shell during use, causing the second side surface 120 of the first shell to be concave inward, in one embodiment, please refer to Figure 2 and Figure 3At least one limiting protrusion 212 is provided on the inner wall of the first side 210 of the second housing. A limiting gap is formed between the limiting protrusion 212 and the groove wall opposite the positioning groove 211 and the limiting protrusion 212. The limiting gap is used to accommodate the positioning protrusion 121, and the dimensions of the positioning protrusion 121 and the limiting gap in the third direction are compatible. The limiting protrusion 212 provides auxiliary support for the second side 120 of the first housing, helping to prevent the second side 120 of the first housing from collapsing under pressure and improving the flatness of the junction between the second side 120 of the first housing and the first side 210 of the second housing.

[0058] In one embodiment, please refer to Figure 1 and Figure 3 The second shell 200 has a second shell third side 230 located on one side of the shell assembly in the first direction. The shell assembly also includes a suction nozzle piece 500 for being set at a suction nozzle setting position. The suction nozzle piece 500 can be detachably set on the second shell third side 230.

[0059] During assembly, after the second housing 200 is assembled to the first housing 100, the mouthpiece 500 is mounted on the third side surface 230 of the second housing. This facilitates the sealed connection between the mouthpiece 500 and the aerosol outlet of the aerosol generating assembly 600. It also prevents the placement of the mouthpiece 500 from interfering with the lateral assembly of the second housing 200, thereby reducing the difficulty of assembling the second housing 200. Furthermore, the mouthpiece 500 serves as a force-bearing portion during disassembly of the second housing 200, transmitting force to the second housing 200 to facilitate disassembly.

[0060] For example, please refer to Figure 1 and Figure 3 The third side surface 230 of the second shell is provided on the side of the second shell 200 where the nozzle is provided in the first direction. The third side surface 230 of the second shell is integrally provided with the first side surface 210 of the second shell and the second side surface 220 of the second shell and smoothly transitions therebetween.

[0061] In one embodiment, please refer to Figure 3 A mounting through hole 231 is provided on the third side surface 230 of the second shell, and the suction nozzle 500 includes a connecting portion 510 inserted into the mounting through hole 231. The connecting portion 510 has an anti-slip protrusion 511 for abutting and limiting the position with the inner wall of the third side surface 230 of the second shell. Among them, one, two or more anti-slip protrusions 511 can be provided around the circumference of the connecting portion 510, and any of them can achieve the anti-slip effect. During installation, the connecting portion 510 is inserted into the mounting through hole 231 so that the anti-slip protrusion 511 passes through the mounting through hole 231 and abuts against the inner wall of the third side surface 230 of the second shell, thereby achieving anti-slip limitation for the suction nozzle 500.

[0062] In addition, when the suction nozzle 500 is applied with force to disassemble the second shell 200, the side of the third side surface 230 of the second shell away from the first side surface 210 of the second shell is easily lifted by the force, which may cause damage. Figure 2 and Figure 3 A first guide structure 310 is provided on the side of the third side 230 of the second shell body close to the second side 120 of the first shell body, and a second guide structure 320 is provided on the second side 120 of the first shell body. The first guide structure 310 can be formed by a physical structural member such as a slide rail or a guide protrusion, so that the first guide structure 310 can be used to strengthen the structure of the third side 230 of the second shell body. This helps prevent the third side 230 of the second shell body from tilting away from the first side 210 of the second shell body when the second shell body 200 is removed using the suction nozzle, thereby reducing the risk of damage.

[0063] For a further embodiment, please refer to Figure 2 and Figure 3 The first guide structure 310 is configured as a slide rail, and the second guide structure 320 is configured as a guide protrusion. The slide rail has a slot 311 along the second direction for the guide protrusion to insert. The slot 311 extends through the end of the slide rail facing away from the first side surface 110 of the first housing, and has an opening near the nozzle assembly 500. The coordinated configuration of the slide rail and the guide protrusion allows the first housing 100 to partially absorb the force acting on the third side surface 230 of the second housing, further reducing the risk of damage.

[0064] In one embodiment, please refer to Figure 3 The inner wall of the first side surface 210 of the second housing has a positioning protrusion 213. The positioning protrusion 213 is used to abut against the aerosol generating assembly 600 installed in the mounting cavity to restrict its movement, thereby improving assembly accuracy and effectiveness. Illustratively, multiple positioning protrusions 213 are provided along the first direction to provide multi-point positioning of the aerosol generating assembly 600. In other embodiments, the positioning protrusion 213 may be provided in one, two, or another number depending on the structure of the aerosol generating assembly 600.

[0065] In one embodiment, please refer to Figure 2 and Figure 3 The connection structure 400 includes at least one connection protrusion 410 provided on the first shell 100 and / or the second shell 200, and at least one connection slot 420 provided on the first shell 100 and / or the second shell 200. The connection protrusion 410 is used to snap into the corresponding connection slot 420 to connect the first shell 100 and the second shell 200. The connection structure 400 connects and secures the first shell 100 and the second shell 200, helping to reduce the risk of the first shell 100 and the second shell 200 separating during use.

[0066] For example, please refer to Figure 2 and Figure 3 The second shell 200 has a second shell fourth side surface 240 located on one side of the shell assembly in the first direction. The second shell fourth side surface 240 is arranged opposite to the second shell third side surface 230. The second shell second side surface 220, the second shell third side surface 230 and the second shell fourth side surface 240 are all provided with connecting slots 420 on the inner walls away from the second shell first side surface 210. The first shell first side surface 110 has connecting protrusions 111 extending along the second direction at both ends of the first direction.
