Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an aerosol delivery device. Background Technology

[0002] Existing manufacturers are adding screens to their products to display various operational statuses of the aerosol delivery system, providing users with easily identifiable information. Such products include... Figure 2 As shown, the aerosol delivery device includes a housing 20, a display unit 30 mounted on the housing 20, and a bracket 10 mounted on the housing 20. The assembly method involves setting an elastic buckle 31 on the display unit 30 and a fastening structure on the housing 20 to cooperate with the elastic buckle 31. During assembly, the elastic buckle 31 is inserted into the mounting opening of the housing 20, and the tension of the buckle's spring arm causes the buckle head to engage with the inner wall of the housing 20. However, in actual disassembly and assembly processes, the spring arm is prone to breakage, and the buckle may become stuck during disassembly, requiring destructive disassembly and resulting in costly rework for engineering maintenance. Utility Model Content

[0003] The main purpose of this invention is to propose an aerosol delivery device that can solve the problem of difficult disassembly and assembly of existing aerosol delivery devices.

[0004] To achieve the above objectives, this application provides an aerosol delivery device, comprising:

[0005] The outer shell has an inner wall that defines a receiving cavity. The outer shell is provided with a first mounting port and a second mounting port. The first mounting port is located on a first plane and communicates with the receiving cavity. The second mounting port is located on a second plane and communicates with the receiving cavity. The first plane is perpendicular to the second plane.

[0006] Screen components, including:

[0007] The bracket has a first contact portion and an extension portion, the extension portion being exposed in the receiving cavity after the screen assembly is connected to the receiving cavity, and the first contact portion being able to be received in the receiving cavity;

[0008] The display portion has a second contact portion that can be detachably connected to the first contact portion;

[0009] When the second contact portion is connected to the first contact portion, the screen assembly and the receiving cavity are interference-fitted; and

[0010] At least one of the bracket and the display unit undergoes a recoverable deformation during the installation of the screen assembly and the receiving cavity, causing the display unit to engage with the second mounting port.

[0011] When the screen assembly is assembled with the housing, the screen assembly is interference-fitted with the receiving cavity, causing at least one of the display part and the bracket to undergo recoverable deformation. When the display part aligns with the second mounting port, the interference fit compresses the display part and locks it into the second mounting port.

[0012] In some embodiments, the bracket includes a first wall and a second wall arranged in parallel, wherein at least one of the first wall and the second wall is capable of recoverable deformation when it comes into contact with the display unit.

[0013] In some embodiments, the first wall or the second wall includes a first contact surface and a second contact surface spaced apart, and a first receiving portion is formed by a recess between the first contact surface and the second contact surface. The wall of the first receiving portion near the first contact surface is an inclined surface, and the inclined surface is connected to the first contact surface.

[0014] Furthermore, the second contact portion includes a third contact surface and a fourth contact surface spaced apart, at least one of the third contact surface and the fourth contact surface being parallel to the first contact surface, and the third contact surface and the fourth contact surface being recessed to form a second receiving portion.

[0015] In some embodiments, a gap is defined between the first contact portion and the second contact portion, the gap forming a deformation space for accommodating the deformable portion.

[0016] In some embodiments, the display portion has an arched cross-section, and a forming chamber is defined between the inner wall of the arch and the bracket.

[0017] In some embodiments, the screen assembly further includes a circuit board housed in the chamber.

[0018] In some embodiments, the outer surface of the display portion has a plurality of protruding ribs extending along the assembly direction of the screen assembly.

[0019] In some embodiments, the surface of the rib that contacts the receiving cavity is an arc surface.

[0020] In some embodiments, the display portion is made of a transparent material.

[0021] Compared with the prior art, this utility model eliminates the need for snap-fit ​​screen components, simplifying the assembly and disassembly of the aerosol delivery device. For example, during assembly, the screen component is interference-fitted with the receiving cavity, causing at least one of the display section and the bracket to undergo recoverable deformation. When the display section aligns with the second mounting port, the interference fit compresses the display section into the second mounting port. When the screen component needs to be disassembled, simply push the outer casing to slowly separate the display section from the bracket, or press down on the display section to release the second mounting port from the display section, thus separating the display section from the outer casing.

[0038] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In the description of this application, unless otherwise expressly specified and defined, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly defined. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] This application provides an aerosol delivery device 1, which includes a screen assembly and a housing 20. The housing 20 defines a receiving cavity inside and has a first mounting port 21 and a second mounting port 22, which are respectively connected to the receiving cavity. The screen assembly includes a display section 30 and a support 10. During assembly, the screen assembly is interference-fitted with the receiving cavity, and the portion of the display section 30 used for displaying content is exposed from the second mounting port 22, allowing the user to obtain the content provided by the supplier through the screen assembly via the exposed portion.

[0041] The outer casing 20 has a hollow interior, and its inner wall 201 defines a receiving cavity for housing a screen assembly. The outer casing 20 is provided with a first mounting port 21 and a second mounting port 22, which communicate with the receiving cavity. The first mounting port 21 is located on a first plane and communicates with the receiving cavity, while the second mounting port 22 is located on a second plane, which is perpendicular to or intersects the first plane. The second mounting port 22 communicates with the receiving cavity. The second mounting port 22 is used to fix the display unit, and at least a portion of the display unit is adapted to the size of the second mounting port 22.

[0042] In some embodiments, the perpendicular or intersecting directions of the first and second planes define the assembly direction of the screen assembly and the housing 20. For example... Figure 3 The direction indicated by the middle arrow is the assembly direction of the screen assembly and the housing 20.

[0043] The screen assembly includes a detachable display unit 30 and a support 10. The support 10 has a first contact portion and an extension portion. The first contact portion can be installed within a receiving cavity and contacts the inner wall 201 and the display unit 20. Specifically, one side of the first contact portion contacts the inner wall 201 of the housing 20, and the other side of the first contact portion supports the display unit 30 and contacts the housing 20, thus fixing the display unit 30 to the housing 20. The extension portion can be integrally formed with the first contact portion. After the first contact portion is installed into the receiving cavity, the extension portion is exposed outside the receiving cavity and serves as a gripping part for assembling and disassembling the screen assembly.

[0044] In some embodiments, the first contact portion has a first wall and a second wall arranged in parallel, and at least one of the first wall and the second wall can undergo recoverable deformation when it abuts against the display portion. Specifically, at least one of the first wall and the second wall is a thin wall. The first wall extends horizontally along the assembly direction and contacts the display portion 30 in a plane perpendicular to the assembly direction, and the second wall extends horizontally along the assembly direction and contacts the inner wall in a plane perpendicular to the assembly direction. When the thin wall is pressed or squeezed, the force point of the thin wall will deform in the direction of force extension to form a recess or shorten the distance between the first wall and the second wall. The recess can accommodate part of the display portion 30, so that the screen assembly can be driven by external force within the space constraint of the receiving cavity, thereby assembling the screen assembly into a preset position. It is understood that both the first wall and the second wall can be used as the first contact portion as described above; in addition, the first wall and the second wall can also be two sides of the bracket arranged in parallel along the assembly direction, one side of which is connected to the display portion 30, and the other side of which abuts against the inner wall during the assembly process. In some embodiments, the support 10 is a plastic part, and when the first wall or the second wall is thin-walled, it can deform under external pressure and recover after the external force is removed.

[0045] In some embodiments, the first wall and the second wall are spaced apart, and the spaced apart can accommodate other components of the aerosol delivery device.

[0046] like Figure 4 As shown, the first wall, serving as the surface in contact with the display unit 30, includes a first contact surface 103 and a second contact surface 101 located on the same horizontal plane and spaced apart. The first contact surface 103 is located at one end near the first mounting opening 21, and the second contact surface 101 is located at one end near the second mounting opening 22. A first receiving portion 102 is formed by a recess between the first contact surface 103 and the second contact surface 101. In some embodiments, the first wall is made of a deformable material, including but not limited to silicone or rubber, such as plastic. When the plastic wall is subjected to external force, it undergoes recoverable deformation, and the plastic wall returns to its initial shape after the external force is removed.

[0047] The second wall, which is the surface in contact with the inner wall, can also have the same structure as the first wall so that the second wall can deform when the support is compressed.

[0048] At least one of the first contact surface 103 and the second contact surface 101 is parallel to the second plane. The first contact surface 103 and the second contact surface 101 support the display part 30 to contact the inner wall 201. The first receiving part 102 defines a deformation space. When the display part 30 or the bracket 10 is deformed by an external force, the deformation space can accommodate the portion of the display part 30 or the bracket 10 that protrudes into the first receiving part 102 due to deformation.

[0049] The first contact portion also includes a first guide surface 100, which forms an obtuse angle with either the first contact surface 103 or the second contact surface 101. This allows for the formation of more non-contact surfaces between the first contact portion and the second contact portion 33, defining a deformation space between these non-contact surfaces. Furthermore, when disassembling the screen assembly, relative movement can occur between the display portion 30 and the support 10, changing the contact surfaces between them, with the original contact surfaces being accommodated within the deformation space.

[0050] In some embodiments, the wall of the first receiving portion 102 near the first contact surface 103 is inclined, and the inclined surface connects with the first contact surface 103. This inclined surface can guide the second contact portion 33 to slide into the first receiving portion 102. It is understood that the first contact surface 103 and the second contact surface 101 can be on the same plane to support the display portion 30, so that the display portion 30 remains stable during assembly. Figure 3 As shown, the bracket 10 and the display unit 30 are connected to form a screen assembly. The screen assembly and the receiving cavity are interference-fitted. During the interference fit, the bracket 10 or the display unit undergoes recoverable deformation, allowing the screen assembly to move from the first mounting port 21 to the second mounting port 22 under external force. During the interference fit, when the display unit 30 moves to the position of the second mounting port 22, a portion of the display unit is exposed to the second mounting port 22. This portion is no longer restricted by the receiving cavity, and the exposed portion is locked within the second mounting port 22. At the same time, the exposed portion can form part of the surface of the outer casing 20 and is flush with the surface of the outer casing 20.

[0051] The display section 30 can be made of a transparent material or a decorative panel with content. One side of the display section 30 is connected to a first contact portion on the bracket 10 to form a screen assembly. Figure 8 As shown, the display unit 30 has a second contact portion 33 parallel to the first contact portion, and the second contact portion 33 can abut against the first contact portion to form a screen assembly.

[0052] The display unit 30 can be combined with the bracket 10 to form at least two types of screen components.

[0053] The first form of the screen assembly: the first contact portion and the second contact portion 33 abut against each other, and the screen assembly is interference-fitted with the receiving cavity.

[0054] The second form of the screen assembly: the second contact portion 33 is combined with the first receiving portion 102, and the screen assembly and the receiving cavity form a clearance fit.

[0055] Understandably, in the first form, the screen component has a first height, and in the second form, the screen component has a second height, with the first height being greater than the second height.

[0056] The second contact portion 33 has a surface that contacts the bracket 10 and a surface that contacts the inner wall 201. Specifically, the second contact portion 33 has a contact surface that is substantially parallel to the first contact portion, and other surfaces of the display portion 30 that are away from or away from this contact surface can form contact with the receiving cavity. In some embodiments, the second contact portion 33 is made of a deformable material, which includes, but is not limited to, silicone or rubber materials, such as plastic. The wall of the display portion 30 that contacts the bracket 10 or the housing 20 is made into a thin wall, which can deform when subjected to external force and return to its initial shape after the external force is removed.

[0057] like Figure 4-5 As shown, the second contact portion 33 is constructed as an arch with a top and sides. The chord length of the arch is greater than or equal to the distance between the two side walls of the receiving cavity. When the side or top of the second contact portion 33 is pressed, the second contact portion 33 deforms, thereby causing the screen assembly to form an interference fit with the receiving cavity. Specifically, when the display portion 30 is inserted into the receiving cavity, the side of the arch is restricted by the receiving cavity and extends in a direction perpendicular to the chord length of the arch. The chord length decreases while the arch height increases, and the second contact portion 33 presses the bracket 10 against the inner wall 201.

[0058] Furthermore, an arched second contact portion 33 and the support 10 define a chamber with a receiving space, which can accommodate other components of the aerosol delivery device. For example, the aerosol delivery device also includes a circuit board, which is housed in the chamber.

[0059] like Figure 4-5As shown, the second contact portion 33 includes a third contact surface 330 and a fourth contact surface 332 spaced apart. At least one of the third contact surface 330 and the fourth contact surface 332 is parallel to the first contact surface 103, and the third contact surface 330 and the fourth contact surface 332 are recessed to form a second receiving portion 331. See also Figure 8 As shown, when the third contact surface 330 is parallel to the first contact surface 103, the screen assembly can form a first shape and be interference-fitted with the receiving cavity during the assembly process.

[0060] When the screen assembly is in the first configuration, a deformation space is defined between the second receiving portion 331 and the first receiving portion 102. The deformation space is used to accommodate the portion of the display portion 30 or the bracket 10 that protrudes due to deformation during the screen assembly process.

[0061] The second contact portion 33 also includes an arc-shaped second guide surface 333, which is formed at the end of the display portion 30 and is connected to the third contact surface 330 or the fourth contact surface 332. When the display portion 30 is in contact with the bracket 10, the third contact surface 330 or the fourth contact surface 332 can be combined with the first receiving portion 102, and the second guide surface 333 can guide the third contact surface 330 or the fourth contact surface 332 to move smoothly out of the first receiving portion 102.

[0062] like Figures 7-8 As shown, the screen assembly is in the first state, and the screen assembly is interference-fitted with the receiving cavity. At least one of the display part 30 and the bracket 10 is deformed. Both are bent towards the deformation space by the pressure of the inner wall 201, so that the screen assembly can continue to move into the receiving cavity through deformation until it is assembled into a preset position and fixed.

[0063] like Figure 9-10 As shown, the screen assembly is in the second configuration, with the first contact portion and the second contact portion 33 engaging in a concave-convex fit. It is understandable that when the screen assembly is disassembled, the contact surface between the display portion 30 and the bracket 10 changes, and the screen assembly passively forms the second configuration.

[0064] In some embodiments, when disassembling the aerosol delivery device 1, the user can apply force to the housing 20 or the screen assembly to separate them. During the separation process, the display part 30 cannot move under the locking of the second mounting port 22. The housing 20 and the display part 30 separate together from the bracket 10. When the display part 30 separates from the bracket 10, the first receiving part 102 and the second receiving part 331 are misaligned. The first contact surface 103 is inserted into the second receiving part 331, and the third contact surface 330 is inserted into the first receiving part 102. The screen assembly is deformed into a second state, and the screen assembly and the receiving cavity form an adaptation or clearance fit. The bracket 10 is more easily detached from the housing 20.

[0065] In some embodiments, when disassembling the aerosol delivery device 1, the user can apply pressure to the deformable display 30 to deform the display 30. The portion of the display 30 corresponding to the second receiving portion 331 deforms and protrudes towards the first receiving portion 102. At the same time, the user can also press down on the display 30 to move the bracket 10 out of the receiving cavity until the screen assembly is separated from the housing 20.

[0066] In some embodiments, the opposing surfaces of the display portion 30 and the receiving cavity are provided with a plurality of protruding ribs 334 distributed along the assembly direction. The protruding ribs 334 can reduce the contact area between the display portion 30 and the receiving cavity, facilitating the movement of the screen assembly within the receiving cavity. The surface of the protruding rib 334 that contacts the inner wall 201 is an arc surface. Further, the protruding rib 334 is made of a deformable material. Specifically, a plurality of protruding ribs 334 can be formed on the surface of the second contact portion 33 that contacts the outer casing 20. Initially, the protruding ribs 334 are approximately perpendicular to the plane containing the inner wall 201 of the outer casing 20. When the display portion 30 and the outer casing 20 move relative to each other, the protruding ribs 334 deform under friction and deviate to one side. After the protruding ribs 334 separate from the inner wall 201, the protruding ribs 334 can return to a shape approximately perpendicular to the plane containing the inner wall 201.

[0067] In some embodiments, the rib 334 may also be made of silicone or rubber material and fixed to the display part 30 by means of hot melting, bonding or embedding.

[0068] The display unit 30 also includes a protrusion 32 extending from the surface of the second contact portion 33. The protrusion 32 is made of a transparent material and is used to display content provided by the manufacturer to the user. The content may be the e-liquid volume displayed through the protrusion 32, or light emanating from the protrusion 32. Furthermore, the light can form text or images. For example... Figure 6 As shown, a protrusion 32 protrudes from the second contact portion 33. (As indicated...) Figure 8 As shown, during the assembly process, the protruding part 32 is locked in place at the second mounting port 22 with the support of the bracket 10.

[0069] During the disassembly of the aerosol delivery device, the display unit can be pressed down at the second mounting port 22, pressing the display unit 30 under the plane of the second mounting port 22, causing the screen assembly to deform. The deformed screen assembly forms a movable gap with the receiving cavity, pulling the bracket 10 or pushing the display unit. For example... Figure 11 As shown, the bracket 10 or screen assembly is removed from the receiving cavity.

[0070] In some embodiments, at least one of the display portion 30 and the bracket 10 has a protruding rib 334 that contacts the inner wall 201 of the housing 20. Specifically, the protruding rib 334 is constructed on the contact surface between the display portion 30 and the housing 20, or the contact surface between the bracket 10 and the housing 20, to reduce the contact area between the display portion 30, the bracket 10 and the housing 20; at the same time, the protruding rib 334 deforms under pressure, which can reduce the width, length, thickness or height of the display portion 30 or the bracket 10.

[0071] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
