Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette structures, specifically to an electronic cigarette structure with grounding protection. Background Technology
[0002] As consumer demand for e-cigarettes becomes increasingly diversified, the design of large-capacity replaceable cartridges offers consumers a personalized option. The replaceable cartridges are housed within the metal casing of the e-cigarette device, which is detachably connected to the mouthpiece. A charging port is located at the bottom of the metal casing for charging the e-cigarette. The metal shield of the charging port contacts the metal casing, thus grounding the circuit board. However, due to the space reserved at the charging port for the circuit board and charging interface, the metal casing is sometimes suspended at this point. Therefore, during production or daily use, if the metal casing is not properly assembled or is displaced by impact, the charging port may not reliably ground, leading to charging problems or leakage. Utility Model Content
[0003] To address the problems in the existing technology, this utility model provides a grounding-protected electronic cigarette structure that can achieve grounding protection for the charging interface, ensuring reliable connection to the power supply ground.
[0004] This utility model relates to a grounded electronic cigarette structure, comprising a metal shell and an insulating support disposed inside the metal shell. The insulating support is provided with a charging circuit board and a charging interface connected to the charging circuit board. The metal shell has a through hole for inserting a charging plug for charging at a position corresponding to the charging interface. The charging interface has terminals and a metal shielding cover surrounding the terminals. A conductive buffer structure is provided between the side of the metal shielding cover away from the charging circuit board and the inner surface of the metal shell. The metal shielding cover is reliably grounded to the metal shell through the conductive buffer structure.
[0005] Furthermore, the conductive buffer structure includes a buffer protective layer, a conductive fiber layer disposed on one side of the buffer protective layer, a first metal plating layer enclosing the buffer protective layer, a conductive treatment layer disposed on the surface of the first metal plating layer, and a second metal plating layer disposed on the surface of the conductive treatment layer.
[0006] Furthermore, a first metal plating layer is also provided between the buffer protective layer and the conductive fiber layer.
[0007] Furthermore, the conductive fiber layer of the conductive buffer structure is fixed to the metal shield of the charging interface with conductive adhesive.
[0008] Furthermore, the conductive fiber layer is a silver-plated glass fiber mesh, and the first metal plating layer and the second metal plating layer are made of nickel or copper.
[0009] Furthermore, the insulating bracket has ribs on both sides of the charging interface to limit the conductive buffer structure.
[0010] Furthermore, an observation window is provided at a position corresponding to the middle of the metal casing and the conductive buffer structure.
[0011] Furthermore, the electronic cigarette structure also includes a button cap structure covering the operation button, the button cap structure having locking feet, and the insulating bracket having buckles corresponding to the locking feet, the button cap structure being engaged with the insulating bracket.
[0012] Furthermore, the button cap includes a soft rubber part that contacts the operation button, a hard rubber part covering the soft rubber part, a button cap covering the hard rubber part, and the retaining pin is disposed on the hard rubber part.
[0013] Furthermore, the buckle is disposed on both sides of the button, and the soft rubber part has protrusions on both sides of the back of the button, and the protrusions are fitted with the gap between the button and the side wall of the buckle.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting a conductive buffer structure between the metal shell and the metal shield of the charging interface, the metal shield of the charging interface and the metal shell can be reliably contacted through the conductive buffer structure.
[0015] Since the conductive buffer structure serves to support and reinforce the connection, and also has a buffering function, when the electronic cigarette is subjected to impact or friction, the conductive buffer structure can effectively protect the internal structure of the electronic cigarette and also prevent grounding problems caused by the displacement of the charging port.

[0021] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.
[0022] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0024] like Figures 1-4 As shown, the electronic cigarette structure with grounding protection of this utility model includes a cigarette rod and a mouthpiece 1 disposed above the cigarette rod. The cigarette rod includes a metal shell 2 and a protective patch 3 covering the upper and lower surfaces of the metal shell 2 to improve wear resistance. A button cap structure 4 for operating the electronic cigarette is also provided on the left side of the metal shell 2. A protective lens 5 is also provided on the upper surface of the display screen. It also includes an insulating bracket 9 disposed inside the metal shell 2. The insulating bracket 9 is provided with a charging circuit board 7 and a charging interface 6 connected to the charging circuit board 7. The metal shell 2 has a through hole for inserting a charging plug for charging at the corresponding position of the charging interface 6. The charging interface 6 has terminals and a metal shielding cover surrounding the terminals. A conductive buffer structure 8 is provided between the side of the metal shielding cover away from the charging circuit board 7 and the inner surface of the metal shell 2. The metal shielding cover is reliably grounded to the metal shell 2 through the conductive buffer structure 8.
[0025] This invention establishes a conductive buffer structure 8 between the metal housing 2 and the metal shield of the charging interface 6, ensuring reliable contact between the metal shield of the charging interface 6 and the metal housing 2. Since the conductive buffer structure 8 provides support and reinforcement, as well as cushioning, it effectively protects the internal structure of the electronic cigarette from impacts or friction, and also prevents grounding issues caused by displacement of the charging port. During assembly or use, even when replacing the cartridge and assembling the detachable metal housing 2, reliable grounding of the charging interface 6 is still possible even if it is not fully pushed into place. This invention ensures good contact between the metal end of the cigarette holder (i.e., the metal housing) and the grounding terminal of the circuit board, protecting its internal electronic components.
[0026] Preferably, in this example, the insulating bracket 9 has ribs 901 on both sides of the conductive buffer structure 8 installed on the charging interface 6 to limit the conductive buffer structure 8. In this example, the gap width between the two ribs 901 is greater than the width of the conductive buffer structure 8, so that when the conductive buffer structure 8 is in interference fit contact with the metal shell 2, space is provided for the conductive buffer structure 8 to deform.
[0027] In addition, in order to overcome the problem of improper installation during disassembly and assembly of the metal housing 2, this example provides an observation window 201 on the metal housing 2 at a position corresponding to the middle of the conductive buffer structure 8. Marks can be set on the conductive buffer structure 8, and the user or staff can directly see whether the conductive buffer structure 8 is installed properly by looking at the marks through the observation window 201.
[0028] In a preferred embodiment of this utility model, the conductive buffer structure 8 can be a cylinder, cuboid, etc., and includes a buffer protective layer, a conductive fiber layer disposed on one side of the buffer protective layer, a first metal plating layer enclosing the buffer protective layer, a conductive treatment layer disposed on the surface of the first metal plating layer, and a second metal plating layer disposed on the surface of the conductive treatment layer. In this example, another first metal plating layer can also be disposed between the buffer protective layer and the conductive fiber layer to improve the conductivity.
[0029] In this example, the buffer protective layer can be a structure such as sponge or silicone. In this example, conductive sponge is preferred as the base layer of the conductive buffer structure 8. It is produced by polymer composite material foaming technology, has uniform foam pore size, and is soft and elastic. Such a structure can provide good buffer protection and protect the device pins from damage.
[0030] In this example, the conductive fiber layer can be made of conductive fabric, such as silver-plated fiberglass mesh, to provide additional strength and conductivity. The conductive fiber layer can enhance the overall structure, improving the durability and tensile strength of the conductive sponge.
[0031] In this example, the conductive fiber layer of the conductive buffer structure is fixed to the metal shield of the charging interface with conductive adhesive.
[0032] The first metal plating layer in this example can be made of nickel, copper, or other conductive metals to ensure good electrical conductivity. The second metal plating layer is located on the outermost layer and provides the final conductivity and protection. This layer can be made of the same material as the first metal plating layer to ensure the electrical continuity and shielding effectiveness of the entire structure.
[0033] In this example, the conductive treatment layer is a chemical treatment or adhesive to ensure good bonding and conductivity between the first metal plating layer, the conductive fiber layer, and the second metal plating layer.
[0034] The multi-layered structure of the conductive buffer structure 8 in this preferred embodiment provides excellent electromagnetic shielding effectiveness, increasing it to over 90 dB over a wide frequency range. Furthermore, it provides a good conductive path, enabling its use for grounding and electrostatic discharge (ESD) protection. The combination with the metal plating provides additional strength, allowing the conductive sponge to maintain softness while also possessing good durability. Additionally, the conductive sponge exhibits good corrosion resistance, making it suitable for long-term device storage and protecting the device from corrosion. The conductive sponge also typically has good flame retardant properties, meeting UL94 HB and V0 flame retardant ratings.
[0035] like Figure 3 and Figure 4 As shown, in this example, the traditional button cap structure often increases the difficulty of installation and maintenance costs during the disassembly of the metal casing 2, while also affecting the user experience. Furthermore, traditional button caps may introduce dust and impurities during disassembly and assembly, which not only reduces the button's responsiveness but may also affect the overall performance of the e-cigarette device. Therefore, this example optimizes the button cap structure, allowing users to quickly disassemble and reinstall the button caps without disassembling the internal structure of the e-cigarette.
[0036] The button cap structure 4 in this example includes a soft rubber part 403 that contacts the operation button 10, a hard rubber part 402 covering the soft rubber part 403, and a button cap 401 covering the hard rubber part 402. The hard rubber part 402 is provided with a locking foot 4021, and the insulating bracket 9 is provided with a buckle 11 corresponding to the locking foot 4021. The button cap structure 4 is engaged with the insulating bracket 9.
[0037] The buckles 11 are located on both sides of the button 10. The soft rubber part 403 has protrusions 4032 on both sides near the back of the button 10. The middle part 4031 of the soft rubber is a flat surface that contacts and mates with the button 10. The protrusions 4031 are fitted with the gap between the button 10 and the side wall of the buckles 11. The soft rubber part 403 is preferably made of silicone, which is waterproof and dustproof.
[0038] In this example, the rigid plastic component 402 serves as the support structure for the entire button cap structure. A groove matching the shape of the upper surface of the soft plastic component 403 is provided in the middle of the lower surface of the rigid plastic component 402 for mounting the soft plastic component 403. The upper surface has a stepped surface, and a raised ring is provided on the back of the button cap 401, which fits the stepped surface, thus allowing the lower surface 4011 of the button cap 401 to be firmly mounted on the rigid plastic component 402. This example optimizes the structure and materials of the button cap structure 4 by embedding button silicone in the contact surface between the button cap structure and the button, ensuring that the button's tactile feel and function remain consistent even after multiple disassemblies and reassemblies. A clip is provided at the insulating bracket 9 to engage with the button cap, simplifying the disassembly and assembly process of the smoking device and improving production efficiency.
[0039] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
