Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a sliding cover structure and an electronic cigarette. Background Technology
[0002] An electronic cigarette is an electronic device that mimics a traditional cigarette. It mainly consists of a battery, an atomizer, an e-liquid storage chamber, and a mouthpiece. Powered by the battery, the atomizer heats the e-liquid to produce vapor for the user to inhale. When replacing the cartridge in a closed-system electronic cigarette, simply remove the old cartridge from the socket and insert the new one.
[0003] The cigarette holder in e-cigarette products usually needs a sliding cover to cover dust or the internal structure. Since users need to slide the cover to replace the cartridge when using e-cigarettes, the cover needs to be able to withstand at least 50,000 back-and-forth sliding cycles according to the product design requirements. Under such a high frequency of use, the product surface is prone to scratches or other wear. Utility Model Content
[0004] The main purpose of this invention is to propose a sliding cover structure that aims to reduce the likelihood of scratches or other wear on the product surface under high usage frequency.
[0005] To achieve the above objectives, the present invention proposes a sliding cover structure for use in electronic cigarettes. The sliding cover structure includes:
[0006] The bottom cover has a sliding surface, on which a positioning hole and a through hole for the smoke cartridge to pass through are formed. The sliding surface has multiple protrusions formed at least on the outer periphery of the positioning hole and the through hole.
[0007] A sliding cover assembly includes a sliding cover, a pull rod, and a slider. The pull rod passes through the positioning hole and is detachably connected to the slider. The slider is slidably connected to the sliding cover. The sliding cover slidably abuts against at least a portion of the protrusions on the sliding surface.
[0008] The sliding cover structure has an open state and a closed state; when the sliding cover structure is in the closed state, the sliding cover covers the through hole; when the sliding cover structure is in the open state, the through hole is exposed on the sliding cover.
[0009] This utility model also proposes an electronic cigarette, which includes a main body and the aforementioned sliding cover structure. The main body is detachably connected to the bottom cover. The main body has a cigarette insertion port, which communicates with the through hole and is provided corresponding to the through hole. Attached Figure Description

[0026] To solve the above problems, this utility model proposes a sliding cover structure 1000. Figures 1 to 7 This is a schematic diagram of an embodiment of the sliding cover structure 1000 of this utility model.
[0027] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 In one embodiment of this utility model, the sliding cover structure 1000 includes a bottom cover 1 and a sliding cover assembly. The bottom cover 1 has a sliding surface 1a, on which a positioning hole 1a1 and a through hole 1a2 for the smoke cartridge to pass through are provided. The sliding surface 1a has at least a plurality of protrusions 11 formed on the outer periphery of the positioning hole 1a1 and the through hole 1a2. The sliding cover assembly includes a sliding cover 21, a pull rod 22 and a slider 23. The pull rod 22 passes through the positioning hole 1a1 and is detachably connected to the slider 23. The slider 23 is slidably connected to the sliding cover 21. The sliding cover 21 slidably abuts against at least a portion of the protrusions 11 on the sliding surface 1a. The sliding cover structure 1000 has an open state and a closed state. When the sliding cover structure 1000 is in the closed state, the sliding cover 21 covers the through hole 1a2. When the sliding cover structure 1000 is in the open state, the through hole 1a2 is exposed on the sliding cover 21.
[0028] Among them, the sliding surface 1a refers to the plane in contact between the bottom cover 1 and the sliding cover 21 assembly, which is used to guide the movement of the sliding cover 21; the through hole 1a2 is the channel for the cartridge to enter and exit; the protrusions refer to the raised structures distributed on the sliding surface 1a, such as hemispherical or cylindrical protrusions, which are used to reduce the contact area between the sliding cover 21 and the bottom cover 1; the detachable connection between the pull rod 22 and the slider 23 is achieved through a threaded structure, a snap-fit structure or a pin structure.
[0029] It should be noted that the sliding cover 21 slides against at least some of the protrusions 11 on the sliding surface 1a, which means that the sliding cover 21 can always maintain contact with the different protrusions 11 formed on the sliding surface 1a when it is in the open state, the closed state, or the movement path switching between the two.
[0030] In the technical solution of this utility model, the user pushes the sliding cover 21 to slide it under the common limit of the sliding surface 1a of the bottom cover 1 and the slider 23, so as to switch the sliding cover structure 1000 between the open state and the closed state. By arranging multiple protrusions 11 on the bottom cover 1 to form a sliding contact surface, the contact area can be reduced when the sliding cover 21 slides, thereby reducing the wear between the bottom surface of the sliding cover 21 and the bottom cover 1. By forming multi-point contact with the bottom cover 1 when the sliding cover 21 slides, large-area friction is avoided, which can significantly reduce scratches or other wear caused by friction on the sliding cover 21, thereby extending the service life of the sliding cover structure 1000 and making it easier to meet the requirement that the sliding cover structure 1000 in electronic cigarettes must withstand at least 50,000 back-and-forth sliding cycles.
[0031] It is worth mentioning that the material of the bottom cover 1 can be PC plastic, metal, or other plastics, and this utility model does not impose any restrictions here.
[0032] The specifications of each protrusion 11 include, but are not limited to: a height between 0.1mm and 0.15mm, a diameter between 0.8mm and 1.5mm, a top chamfer between 0.05mm and 0.1mm, and a maximum spacing of 0.5mm between adjacent protrusions 11.
[0033] It is understandable that the connection between the sliding cover 21 and the slider 23 can be such that the sliding cover 21 forms a groove on the side wall facing the bottom cover 1, and the slider 23 is limited to slide within the groove by two limiting rods; alternatively, the sliding cover 21 forms a stepped hole 21a, with a larger opening on the side wall of the sliding cover 21 away from the bottom cover 1, and the slider 23 slides within the stepped hole 21a. Please refer to [link / reference]. Figure 2 , Figure 3 as well as Figure 5 In one embodiment of the present invention, the sliding cover 21 is formed with a stepped hole 21a, and the pull rod 22 passes through the positioning hole 1a1 and the stepped hole 21a and is detachably connected to the slider 23. The slider 23 is slidably connected to the stepped surface of the stepped hole 21a on the side wall facing the bottom cover 1.
[0034] The stepped surface of the stepped hole 21a is used to contact the side wall of the slider 23, providing a sliding guide function. When the user pushes the sliding cover 21 to open or close, the pull rod 22 passes through the positioning hole 1a1 of the bottom cover 1 and the stepped hole 21a of the sliding cover 21 and connects to the slider 23. The side wall of the slider 23 always maintains surface contact with the stepped surface of the stepped hole 21a. During the sliding process, the stepped surface forms a rigid constraint on the movement trajectory of the slider 23, so that the slider 23 can only move in a preset direction, avoiding the slider 23 from deflection or jamming due to uneven force, thereby providing a stable sliding track for the slider 23.
[0035] Please see Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Figure 8 In one embodiment of this utility model, the slider 23 has a limiting bone 231 protruding from the side wall of the bottom cover 1; the stepped surface of the stepped hole 21a has a first limiting groove 21a1 and a second limiting groove 21a2; wherein, when the sliding cover structure 1000 is in the closed state, the limiting bone 231 is engaged in the first limiting groove 21a1; when the sliding cover structure 1000 is in the open state, the limiting bone 231 is engaged in the second limiting groove 21a2.
[0036] The limiting rib 231 refers to the protruding structure extending from the slider 23 towards the bottom cover 1. Its function is to achieve precise positioning of the slider assembly in the open and closed states by cooperating with the limiting groove. Through the cooperation of the limiting rib 231 and the limiting groove, independent locking points are formed in the open and closed states, improving the positioning accuracy of the slider structure 1000 in the open and closed states, ensuring that the slider 21 can stably maintain the preset position in the open and closed states, thereby extending the service life of the slider structure 1000 and improving the user's operating experience.
[0037] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the sliding cover assembly further includes an elastic element 24, which is sleeved on the pull rod 22. The two ends of the elastic element 24 abut against the end of the pull rod 22 away from the slider 23 and the side wall of the bottom cover 1 away from the slider 23, respectively.
[0038] The end of the pull rod 22 away from the slider 23 refers to the opposite end of the connection position between the pull rod 22 and the slider 23, which is used to transmit the compressive reaction force of the elastic element 24. When the sliding cover 21 slides under the action of external force, the pull rod 22 drives the slider 23 to move along the stepped hole 21a. At this time, the elastic element 24 is compressed and accumulates elastic potential energy. After the sliding action is completed, the elastic element 24 releases potential energy to push the pull rod 22 to reset, so that the sliding cover 21 automatically maintains the contact state with the protrusion 11. When the sliding cover 21 is in the closed or open state, the preload of the elastic element 24 can offset the displacement caused by external vibration or accidental contact, and prevent the sliding cover 21 from sliding accidentally. By introducing the axial elastic element 24, dynamic compensation force is provided during the movement of the sliding cover 21, reducing the wear rate of the contact surface, and realizing the self-resetting function of the sliding action.
[0039] Please see Figure 3 and Figure 4 In one embodiment of the present invention, the bottom cover 1 has a mounting protrusion 12 on the side opposite to the slider 23. The mounting protrusion 12 forms a mounting hole 12a that communicates with the positioning hole 1a1. The pull rod 22 and the elastic member 24 are inserted into the mounting hole 12a.
[0040] The mounting protrusion 12 refers to the structure that protrudes outward from the surface of the bottom cover 1. The mounting hole 12a refers to the channel that passes through the mounting protrusion 12, which can be implemented using a cylindrical channel structure. Its function of communicating with the positioning hole 1a1 is to ensure that the pull rod 22 and the elastic element 24 are installed coaxially. By setting the mounting protrusion 12 with the mounting hole 12a, the elastic element 24 is constrained within a fixed space, ensuring that its movement trajectory is always consistent, thereby improving the stability of the sliding cover 21 during the sliding process. Specifically, during the assembly process, the elastic element 24 is pre-fitted onto the outside of the pull rod 22, and then the pull rod 22 together with the elastic element 24 is inserted into the mounting hole 12a.
[0041] Please see Figure 2 , Figure 3 , Figure 5 , Figure 6 as well as Figure 7 In one embodiment of the present invention, the sliding cover 21 includes a cover body 211 and a base 212. The base 212 has a stepped hole 21a and the base 212 is detachably connected to the cover body 211.
[0042] The sliding cover 21 consists of two parts: a cover body 211 and a base 212. The base 212 cooperates with the slider 23 through a stepped hole 21a to achieve the sliding function. The cover body 211 is fixed to the base 212 in a detachable manner. When the surface of the sliding cover 21 wears due to frequent sliding, only the cover body 211 and the base 212 need to be separated to replace the cover body 211 or the base 212 separately, without having to disassemble the entire sliding cover assembly, thereby reducing the maintenance difficulty of the sliding cover structure 1000 during long-term use.
[0043] Specifically, the material of the cover 211 can be PC plastic, metal, or other plastics; this utility model does not impose any restrictions here.
[0044] Similarly, the base 212 can be made of POM material, metal, or other plastics; this utility model does not impose any restrictions on it.
[0045] Specifically, the detachable connection between the base 212 and the cover 211 can be achieved through a bolted connection, a magnetic connection, or a snap-fit connection 2121. Please refer to [link / reference]. Figure 6 and Figure 7 In one embodiment of the present invention, the inner peripheral wall of the cover 211 is formed with a groove 211a, and the outer peripheral wall of the base 212 is formed with a buckle 2121, which is connected to the groove 211a.
[0046] The slot 211a refers to a groove structure provided on the inner peripheral wall of the cover, used to accommodate the latch 2121 on the outer peripheral wall of the base 212 to achieve mechanical locking. The latch 2121 refers to a protrusion structure provided on the outer peripheral wall of the base 212, which elastically deforms and embeds into the slot 211a to restore its shape and form an interlock. Through the elastic interlocking structure of the latch 2121 and the slot 211a, tool-free quick assembly and disassembly can be achieved, and the mechanical interlock ensures the connection strength, thereby reducing the time cost for users to maintain the sliding cover structure 1000; at the same time, while ensuring the reliability of the connection, it can also avoid the problem of wear debris contaminating the cartridge that may be generated by threaded connections.
[0047] The elastic element 24 can be elastic silicone, a spring, or other elastic material. In one embodiment of this invention, the elastic element 24 is a spring. Springs have higher fatigue resistance and durability, and can adapt to high-frequency sliding operations, thereby improving the service life of the sliding cover structure 1000.
[0048] The detachable connection between the pull rod 22 and the slider 23 can be achieved by bolts or by a pin 25. In one embodiment of this invention, the sliding cover assembly further includes a pin 25, through which the pull rod 22 and the slider 23 are connected.
[0049] The pin 25 serves to axially fix the pull rod 22 and the slider 23 by passing through the mating hole. Using the pin 25 for connection not only facilitates disassembly and assembly but also allows for individual replacement of the pin 25 after wear, reducing maintenance costs.
[0050] Specifically, the materials of the pin 25, slider 23 and pull rod 22 can be aluminum alloy, or other hardware or plastic, and this utility model does not impose any restrictions.
[0051] This utility model also proposes an electronic cigarette, which includes a main body and a sliding cover structure 1000. The specific structure of the sliding cover structure 1000 is as described in the above embodiments. Since this electronic cigarette adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The main body and the bottom cover 1 are detachably connected; the main body has a cigarette insertion port, which communicates with and corresponds to the through hole 1a2.
[0052] The detachable connection between the main body and the bottom cover 1 means that the two are detachably fixed through a connection structure, which can be achieved by means of clips, threads, or magnetic adsorption, facilitating the disassembly and maintenance of the main body and the bottom cover 1. The connection and corresponding arrangement between the cigarette insert and the through hole 1a2 means that the positions of the cigarette insert and the through hole 1a2 form an aligned channel after installation. This can be achieved through a positioning structure or size matching, ensuring that the tobacco cartridge can smoothly pass through the cigarette insert and the through hole 1a2 for replacement.
[0053] When the sliding cover structure 1000 is installed on the main body of the electronic cigarette, the bottom cover 1 is fixed to the main body via a detachable connection, and the cigarette insertion port and the through hole 1a2 of the bottom cover 1 form a continuous channel. The sliding cover assembly controls the opening or closing of the through hole 1a2 through a sliding operation: when the sliding cover 21 is in the closed state, it covers the through hole 1a2 to prevent dust from entering the cigarette insertion port; when the sliding cover 21 is slid to the open state, the through hole 1a2 is fully exposed, allowing the cartridge to be inserted or removed. The detachable connection design between the main body and the bottom cover 1 allows the user to clean or replace the bottom cover 1 separately without disassembling the entire electronic cigarette.
[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
