Description

Technical Field

[0001] This utility model relates to the field of sliding cover structure technology, and in particular to a sliding cover structure and an electronic cigarette. Background Technology

[0002] Sliding caps, with their superior protection and dustproof capabilities, have become an indispensable part of many device designs, with a wide range of applications, from e-cigarettes to packaging boxes and mobile devices. Especially in the e-cigarette industry, these devices generate vapor by heating the cigarette, and to ensure effective protection of the cigarette holder or air duct when not in use, designers typically incorporate on / off controls for the cigarette holder or air duct in the sliding cap design.

[0003] However, traditional sliding cover designs often employ an exposed design, requiring users to directly slide the exposed cover itself to control the opening and closing of the cigarette holder or air duct. While this design is simple and intuitive, it also brings some unavoidable problems. Because the sliding cover is exposed, it is more susceptible to external impacts and scratches. These physical damages not only affect the aesthetics but may also weaken the overall durability of the structure; at the same time, they also increase the maintenance costs of the device. Utility Model Content

[0004] The main purpose of this invention is to propose a sliding cover structure and an electronic cigarette, which aims to solve the problem that traditional sliding covers are easily damaged by external impacts and scratches. These physical damages not only affect the appearance but may also weaken the durability of the entire structure.

[0005] To achieve the above objectives, the present invention proposes a sliding cover structure comprising: a housing and a sliding cover assembly; the housing having an installation cavity and a passageway, the passageway connecting the installation cavity to the outside; the sliding cover assembly comprising a first rotating member, a second rotating member, and a transmission arm; the first rotating member rotatably passing through the housing and being drively connected to the second rotating member; the second rotating member rotatably disposed in the installation cavity and capable of blocking the passageway; the transmission arm rotatably connecting the free end of the second rotating member and the first rotating member; when the first rotating member rotates relative to the housing, the first rotating member drives the transmission arm to rotate, thereby causing the second rotating member to open or close the passageway.

[0006] This utility model also proposes an electronic cigarette, which includes a sliding cover structure. Attached Figure Description

[0021] This utility model proposes a sliding cover structure 100.

[0022] Please see Figures 1 to 3 In one embodiment of this utility model, the sliding cover structure 100 includes a housing 1 and a sliding cover assembly 2. The housing 1 forms an installation cavity 1a and a passage 1b, and the passage 1b connects the installation cavity 1a to the outside. The sliding cover assembly 2 includes a first rotating member 21 and a second rotating member 22. The first rotating member 21 is rotatably disposed in the housing 1 and is connected to the second rotating member 22 in a transmission manner. A transmission arm 23 is rotatably connected to the free end of the second rotating member 22 and the first rotating member 21. When the first rotating member 21 rotates relative to the housing 1, the first rotating member 21 drives the transmission arm 23 to rotate, thereby driving the second rotating member 22 to open or close the passage 1b.

[0023] In one embodiment, the housing 1 has a mounting cavity 1a and a passage channel 1b, which penetrates the opposite side walls of the housing 1 and connects the mounting cavity 1a to the outside. The housing 1 is generally made of fire-resistant plastic or high-temperature resistant materials such as aluminum alloy. The mounting cavity 1a and passage channel 1b formed within the housing 1 effectively protect the internal components, preventing dust and foreign objects from entering and enhancing the protective performance of the electronic cigarette. Manufacturing the housing 1 using processes such as injection molding or machining ensures the stability and durability of the structure, reducing the risk of damage caused by external factors. The design of the housing 1 can flexibly adjust the size and shape of the mounting cavity 1a and passage channel 1b as needed to adapt to different models of electronic cigarette products, improving the design flexibility and applicability.

[0024] It should be noted that the sliding cover assembly 2 includes a first rotating component 21 and a second rotating component 22. Both components are typically made of wear-resistant materials such as plastic and aluminum alloy. The first rotating component 21 is rotatably connected to the housing 1 via a hole-shaft fit, and the second rotating component 22 is rotatably connected to the first rotating component 21 via a hole-shaft fit. Simultaneously, the second rotating component 22 can rotate relative to the housing 1, thereby opening or closing the passageway 1b. Through this rotating and sliding connection, the sliding cover assembly 2 can be hidden when not in use, reducing the chance of external collisions and scratches, thus lowering the risk of physical damage and improving the overall durability of the structure. When the first rotating component 21 drives the second rotating component 22 to rotate, the passageway 1b can be effectively opened or closed. When not in use, the passageway 1b is blocked by the second rotating component 22, effectively protecting the internal components from contamination and physical damage, enhancing the device's protective performance. Users can easily open and close the sliding cover by simply rotating the first rotating component 21, making operation simple and quick, and improving the user experience. By optimizing the design of the sliding cover assembly 2, the space occupied by the transmission mechanism can be reduced, which is conducive to platform-based production and improves space utilization. The sliding cover is not exposed when not in use, improving the overall aesthetics of the product. At the same time, by reducing the risk of physical damage, the equipment maintains its aesthetic appearance over the long term.

[0025] The sliding cover assembly 2 includes a transmission arm 23, which can be a metal or plastic rod. One end of the transmission arm 23 is rotatably connected to the first rotating member 21, and the other end is rotatably connected to the second rotating member 22. This connection can be achieved through bearings, hinges, or other mechanical connections, ensuring that the transmission arm 23 can rotate flexibly between the first rotating member 21 and the second rotating member 22. The second rotating member 22 is designed as a flat plate structure, with its edge rotatably connected to the free end of the transmission arm 23. The other end of the second rotating member 22 is rotatably connected to the first rotating member 21. When the first rotating member 21 rotates relative to the housing 1, for example through user operation or an automatic drive mechanism, the rotation of the first rotating member 21 is transmitted to the second rotating member 22 through the transmission arm 23, thereby causing the second rotating member 22 to rotate around the fixed point of the first rotating member 21, realizing the function of opening or closing the passageway 1b. This design can achieve a linkage effect by setting gears and a tension rope, where the gears are responsible for rotational transmission, and the tension rope provides appropriate tension to maintain a tight fit between the structures. Users only need to operate the first rotating component 21 to open and close the passageway 1b via the linkage mechanism of the transmission arm 23 and the second rotating component 22, simplifying the operation process. The design of the transmission arm 23 and the second rotating component 22 makes the entire sliding cover structure 100 more compact, saving space while maintaining structural stability and functionality. The rotating connection design reduces mechanical wear and extends the service life of the sliding cover structure 100, especially under frequent opening and closing conditions. Opening or closing the passageway 1b by rotating the second rotating component 22 effectively protects the internal components from external contamination and physical damage, enhancing the protective performance of the equipment.

[0026] This utility model presents a sliding cover structure 100, which includes a housing 1 and a sliding cover assembly 2. The housing 1 has a mounting cavity 1a and a passageway 1b, the passageway 1b penetrating the opposite side walls of the housing 1 and connecting the mounting cavity 1a to the outside. The sliding cover assembly 2 consists of a first rotating member 21, a second rotating member 22, and a transmission arm 23. The first rotating member 21 is rotatably mounted in the housing 1, while the second rotating member 22 is rotatably mounted in the mounting cavity 1a and can block the passageway 1b. The transmission arm 23 rotatably connects the free end of the second rotating member 22 and the first rotating member 21. When the first rotating member 21 rotates relative to the housing 1, it drives the transmission arm 23 to rotate, thereby opening or closing the passageway 1b. Through the design of the sliding cover assembly 2, when the electronic cigarette is not in use, the passageway 1b is blocked by the second rotating member 22, effectively protecting the cigarette holder or airway from external contamination and physical damage, thus enhancing the device's protective capabilities. The sliding cover is hidden when not in use, reducing the chance of external impacts and scratches, thus lowering the risk of physical damage, improving the overall durability of the structure, and reducing the need for repair and replacement due to physical damage, thereby reducing the maintenance cost of the equipment. Users can easily open and close the sliding cover by simply rotating the first rotating component 21, making operation simple and quick, and improving the user experience.

[0027] In one embodiment of this utility model, please refer to Figure 2 and Figure 5 The inner wall of the housing 1 has a rotating groove 1c, which surrounds the material passage 1b. The first rotating member 21 has a rotating boss 211, which is rotatably disposed in the rotating groove 1c.

[0028] In this embodiment, a rotating groove 1c is formed on the inner wall of the housing 1. This rotating groove 1c is located around the periphery of the passage channel 1b and guides the rotation of the first rotating member 21. Specifically, the rotating groove 1c can be a recess surrounding the passage channel 1b, and its shape and size are designed to match the rotating boss 211 of the first rotating member 21 to ensure that the rotating boss 211 can rotate smoothly within the rotating groove 1c. The first rotating member 21 is provided with a rotating boss 211, which can be a cylindrical or other shaped protrusion. It cooperates with the rotating groove 1c, enabling the first rotating member 21 to rotate inside the housing 1 through the cooperation of the rotating boss 211 and the rotating groove 1c. The rotating boss 211 is rotatably disposed within the rotating groove 1c, meaning that the rotating boss 211 can rotate freely within the rotating groove 1c, thereby realizing the opening and closing action of the sliding cover.

[0029] This process, by forming a rotating groove 1c on the inner wall of the housing 1, ensures the rotational stability of the first rotating component 21 and reduces the risk of damage caused by friction or jamming. The cooperative design of the rotating boss 211 and the rotating groove 1c makes the opening and closing of the sliding cover smoother, improving the user experience. The design of the rotating boss 211 and the rotating groove 1c reduces mechanical wear and extends the service life of the sliding cover structure 100. The design of the first rotating component 21 and the rotating boss 211 makes the sliding cover structure 100 more compact, saving space while maintaining structural integrity and functionality.

[0030] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 Both ends of the transmission arm 23 are provided with transmission shafts 231. The free end of the second rotating member 22 and the first rotating member 21 are provided with transmission holes 21b. The transmission shafts 231 at both ends of the transmission arm 23 are respectively inserted into the free end of the second rotating member 22 and the transmission holes 21b of the first rotating member 21.

[0031] In one embodiment, the transmission arm 23 is designed as a component with transmission shafts 231 at both ends. The transmission shafts 231 at both ends of the transmission arm 23 are extensions of the transmission arm 23, used to connect to the free end of the second rotating member 22 and the first rotating member 21. Both the free end of the second rotating member 22 and the first rotating member 21 have transmission holes 21b, the shape and size of which match the transmission shafts 231, allowing the transmission shafts 231 to be smoothly inserted and installed within them. During actual assembly, the transmission shafts 231 at both ends of the transmission arm 23 are respectively inserted into and fixed within the transmission holes 21b of the free end of the second rotating member 22 and the first rotating member 21, thereby achieving a mechanical connection between the two rotating members. This connection method allows for the conversion of force transmission and motion, enabling the rotation of the first rotating member 21 to be transmitted to the second rotating member 22 via the transmission arm 23. The design of the transmission arm 23 and the transmission shafts 231 ensures effective force transmission, allowing the rotational motion of the first rotating member 21 to be accurately transmitted to the second rotating member 22, thus improving the efficiency of force transmission. The drive shaft 231 is inserted into the drive hole 21b, enhancing the stability of the entire transmission system and reducing structural deformation under high loads. This design allows for adjustment of the length and position of the drive arm 23 in different application scenarios to adapt to various design requirements and space constraints.

[0032] In one embodiment of this utility model, please refer to Figure 3 The inner wall of the housing 1 is provided with a guide shaft 11, and the second rotating member 22 is provided with a rotating hole 22a that cooperates with the guide shaft 11. The guide shaft 11 passes through the rotating hole 22a.

[0033] In this embodiment, the inner wall of the housing 1 is designed with one or more protruding guide shafts 11, which are arranged along the periphery of the passageway 1b. Specifically, the guide shaft 11 can be a cylindrical structure fixed inside the housing 1, and its diameter and length are determined according to the dimensions of the second rotating member 22. The second rotating member 22 has a rotating hole 22a that mates with the guide shaft 11 to ensure that the second rotating member 22 can rotate freely on the guide shaft 11 without generating excessive friction. The guide shaft 11 passes through the rotating hole 22a, which can be a through hole in the middle of the second rotating member 22 to accommodate the rotating shaft, allowing the second rotating member 22 to rotate around the guide shaft 11. In the actual assembly process, the second rotating member 22 is fitted onto the guide shaft 11 through its rotating hole 22a, while the guide shaft 11 passes through the first rotating member 21, thereby realizing the rotational connection between the second rotating member 22 and the first rotating member 21. By providing a guide shaft 11 on the inner wall of the housing 1 and having a matching rotating hole 22a on the second rotating component 22, the precise positioning of the second rotating component 22 when opening or closing the passage 1b can be ensured, improving the operational accuracy of the entire sliding cover structure 100. The cooperative rotation design of the guide shaft 11 and the second rotating component 22 enhances the stability of the second rotating component 22 during rotation, reducing operational errors caused by the second rotating component 22 shaking or shifting. Due to the precise fit between the guide shaft 11 and the rotating hole 22a, friction and wear between the second rotating component 22 and the guide shaft 11 during rotation are reduced, extending the service life of both the second rotating component 22 and the guide shaft 11. The guide shaft 11 makes the second rotating component 22 more reliable when opening or closing the passage 1b, reducing the risk of failure due to improper operation.

[0034] In one embodiment of this utility model, please refer to Figure 3 The first rotating member 21 has a guide hole 21a, which extends along the rotation direction of the first rotating member 21. The guide shaft 11 passes through the guide hole 21a and the rotating hole 22a in sequence.

[0035] In one embodiment, the first rotating member 21 has a guide hole 21a. The guide hole 21a is designed to extend along the rotation direction of the first rotating member 21 to ensure that the guide shaft 11 can pass through smoothly and that the rotating bracket can rotate along a predetermined path. Specifically, the guide hole 21a can be directly machined on the first rotating member 21 and penetrates the opposite side walls of the first rotating member 21. Its shape can be arc-shaped or circular, and its diameter is determined according to the position of the guide shaft 11. The guide shaft 11 passes through the guide hole 21a and the rotating hole 22a in sequence. This means that the guide shaft 11 first passes through the guide hole 21a on the first rotating member 21 and then extends to the rotating hole 22a of the second rotating member 22. In actual assembly, one end of the guide shaft 11 passes through the guide hole 21a of the first rotating member 21, and the other end passes through the rotating hole 22a of the second rotating member 22, realizing the rotational connection between the second rotating member 22 and the first rotating member 21. The design of the guide hole 21a extending along the rotation direction of the first rotating member 21 ensures the correct positioning of the guide shaft 11 within the first rotating member 21, thereby improving the positioning accuracy of the entire sliding cover structure 100. The precise fit between the guide hole 21a and the guide shaft 11 reduces friction and wear between them, extending the service life of both the guide shaft 11 and the first rotating member 21. The design of the guide shaft 11 passing sequentially through the guide hole 21a and the rotating hole 22a simplifies the assembly process and facilitates future maintenance and replacement, improving maintenance convenience. The guide shaft 11 makes the second rotating member 22 more stable when opening or closing the material passage 1b, reducing operational errors caused by the shaking or displacement of the second rotating member 22.

[0036] In one embodiment of this utility model, please refer to Figure 6 The side wall of the rotating groove 1c is provided with a plurality of first protrusions 12, and each first protrusion 12 is spaced apart on the side wall of the rotating groove 1c. When the first rotating member 21 rotates relative to the housing 1, each first protrusion 12 can abut against the rotating protrusion 211.

[0037] In this embodiment, a plurality of first protrusions 12 are provided on the sidewall of the rotating groove 1c. Specifically, a plurality of first protrusions 12 are spaced apart on the sidewall of the rotating groove 1c. These first protrusions 12 can be formed directly by protrusions on the sidewall of the rotating groove 1c, or they can be independent components attached to the sidewall of the rotating groove 1c by welding, bonding or other fixing methods. The number and spacing of the first protrusions 12 are determined according to the size of the rotating groove 1c and the usage requirements to ensure that the first protrusions 12 can effectively protect the sidewall of the rotating groove 1c from damage when the sliding cover assembly 2 moves, while ensuring that the rotating protrusions 211 are subjected to less wear during rotation and reducing the friction of the first rotating component 21 during rotation.

[0038] In one embodiment of this utility model, please refer to Figure 3The housing 1 includes an upper cover 13 and a lower cover 14. The upper cover 13 and the lower cover 14 are detachably connected and enclose to form an installation cavity 1a. The upper cover 13 has a first passage hole 13a and the lower cover 14 has a second passage hole 14a.

[0039] In one embodiment, the housing 1 includes two main parts: an upper cover 13 and a lower cover 14. The upper cover 13 and lower cover 14 are assembled together via a detachable connection to form a mounting cavity 1a. Specifically, the upper cover 13 and lower cover 14 can be connected by threaded connections, snap-fit ​​connections, or other methods, allowing users to easily disassemble and reassemble them as needed. The upper cover 13 has a first passage hole 13a, while the lower cover 14 has a second passage hole 14a. The positions and sizes of these two passage holes are designed to correspond to each other to ensure alignment during assembly, thus forming a continuous passage channel 1b. The dimensions of the first passage hole 13a and the second passage hole 14a can be determined based on the size of the item to be passed through, ensuring unobstructed passage of the passage channel 1b. The detachable connection design of the upper cover 13 and lower cover 14 simplifies the assembly and maintenance of the housing 1, allowing users to easily open the housing 1 to inspect or replace internal components as needed. The corresponding design of the first passage hole 13a and the second passage hole 14a ensures the continuity of the passage channel 1b, allowing both airflow and other substances to pass through smoothly, which is especially important for applications that require control of airflow or material flow.

[0040] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 The lower cover 14 is provided with a second protrusion 131. The second protrusion 131 is located on the side of the lower cover 14 facing the first rotating member 21. When the first rotating member 21 rotates relative to the lower cover 14, the second protrusion 131 can reduce the contact area between the first rotating member 21 and the lower cover 14.

[0041] In this embodiment, the lower cover 14 is designed to include one or more second protrusions 131, which protrude from the side of the lower cover 14 facing the first rotating member 21. Specifically, the second protrusions 131 can be integrally formed with the lower cover 14 by injection molding, or attached to the lower cover 14 by subsequent processing methods such as welding or bonding. The position and number of the second protrusions 131 are determined according to the size and shape of the first rotating member 21 to ensure that they can effectively protect the first rotating member 21 and provide stable support. In the actual assembly process, the first rotating member 21 is installed in the mounting cavity 1a, and the second protrusions 131 are located on the side of the first rotating member 21 facing the lower cover 14, providing additional support and protection for the first rotating member 21, preventing deformation or damage to the first rotating member 21 due to external forces, and reducing the frictional resistance when the first rotating member 21 rotates.

[0042] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 The first rotating member 21 has a protruding actuating part 212, and the upper cover 13 has an actuating hole 13b, through which the actuating part 212 passes.

[0043] In one embodiment, the first rotating member 21 has a protruding actuating part 212, which can be a cylindrical or rod-shaped structure extending from the first rotating member 21. The upper cover 13 has an actuating hole 13b, the shape and size of which match the actuating part 212 so that the actuating part 212 can pass through and move smoothly within it. In actual assembly, the actuating part 212 extends from one side of the first rotating member 21 and accurately enters the actuating hole 13b of the upper cover 13. This design allows the actuating part 212 to rotate freely within the actuating hole 13b, thereby realizing the control or driving function of the first rotating member 21. Through the cooperation of the actuating part 212 and the actuating hole 13b, the user can easily operate the first rotating member 21 to achieve quick positioning or adjustment, improving the convenience of operation. This design makes the connection between the first rotating member 21 and the upper cover 13 more compact, reducing space occupation while maintaining structural integrity and functionality. The combined use of the actuating part 212 and the actuating hole 13b can reduce the shaking of the first rotating part 21 during operation and improve the stability of the entire structure.
