[0034] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.
[0035] like Figures 1 to 12 As shown, this utility model provides a rotary oil-sealing structure, including a mouthpiece 10, a chamber 20, a heating wire assembly 30, a sealing connector 40, and a sealing seat 50. The chamber 20 has a top opening, side walls around its perimeter, and a sealing seat 50 at its bottom. It has an internal hollow cavity structure forming an oil storage chamber 21 for storing e-liquid. The mouthpiece 10 is rotatably mounted on the top of the chamber 20. The heating wire assembly 30 is installed inside the chamber 20, and its top is connected to the chamber 20 through the sealing connector 40 at the opening of the chamber 20. The mouthpiece 10 is connected, and the outer wall of the sealing connector 40 fits against the inner wall of the chamber 20; the sealing seat 50 is provided with an installation cavity 51, and the bottom of the heating wire assembly 30 is inserted into the installation cavity 51; the lower end of the heating wire assembly 30 is provided with an oil inlet hole 31, and the inner wall of the sealing seat 50 is provided with an oil inlet groove 52 that communicates with the oil storage chamber 21; the mouthpiece 10 rotates, causing the heating wire assembly 30 to rotate at a preset angle, so that the oil inlet hole 31 and the oil inlet groove 52 are aligned to open the oil passage between the oil storage chamber 21 and the heating wire assembly 30 or to close the oil passage by misalignment.
[0036] In this embodiment, the rotation of the mouthpiece 10 drives the rotation of the heating wire assembly 30, thereby achieving active control of the oil circuit between the oil storage chamber 21 and the heating wire assembly 30. The "open" and "closed" states of the oil circuit can be switched by mechanical rotation, solving the problem of oil leakage caused by long-term continuous oil circuit in traditional structures. This effectively reduces the occurrence of oil leakage and achieves reliable e-liquid sealing. Furthermore, the outer wall of the sealing connector 40 fits against the inner wall of the chamber 20, forming a radial seal at the opening of the chamber 20, preventing e-liquid or atomized smoke in the oil storage chamber 21 from leaking from the opening gap, further improving the sealing performance of the device.
[0037] Specifically, such as Figure 3 , Figure 4 and Figure 6 As shown, the mouthpiece 10 is rotatably mounted on the top of the chamber 20. The top of the heating wire assembly 30 is connected to the mouthpiece 10 through the sealing connector 40, and the bottom is inserted into the mounting cavity 51 of the sealing seat 50. At this time, the oil inlet 31 at the bottom of the heating wire assembly 30 and the oil inlet groove 52 on the inner wall of the sealing seat 50 are misaligned. The oil passage between the oil storage chamber 21 and the heating wire assembly 30 is closed, and the e-liquid cannot enter the heating wire assembly 30, thus achieving the oil sealing effect during transportation or when idle. like Figure 1 , Figure 2 and Figure 5As shown, when the user rotates the mouthpiece 10 (e.g., counterclockwise), the mouthpiece 10, through the linkage of the sealing connector 40, drives the heating wire assembly 30 to rotate synchronously at a preset angle; as the heating wire assembly 30 rotates, the oil inlet 31 at its bottom gradually aligns with the oil inlet groove 52 on the inner wall of the sealing seat 50. At this time, the e-liquid in the oil storage chamber 21 enters the heating wire assembly 30 through the oil inlet groove 52 and the oil inlet 31, and the oil circuit is opened. When the heating wire assembly 30 is working, it can atomize the e-liquid to produce smoke for the user to inhale. like Figure 3 , Figure 4 and Figure 6 As shown, when the user rotates the mouthpiece 10 in the opposite direction (such as clockwise) to a preset angle, the heating wire assembly 30 rotates and resets, the oil inlet 31 and the oil inlet groove 52 are misaligned again, the oil circuit is closed, and the e-liquid in the oil storage chamber 21 can no longer enter the heating wire assembly 30, thus avoiding e-liquid leakage when not in use. This is especially suitable for scenarios with air pressure changes such as high and low altitude transportation.
[0038] As one implementation method, such as Figure 2 , Figure 7 and Figure 8 As shown, the sealing connector 40 includes a positioning post 41 and a sealing sleeve 42. The two ends of the positioning post 41 are connected to the mouthpiece 10 and the heating wire assembly 30, respectively. The sealing sleeve 42 is fitted onto the outer wall of the positioning post 41 and fits snugly against the inner wall of the chamber 20. In this embodiment, the mouthpiece 10 is fitted onto the upper end of the chamber 20 and the positioning post 41. The lower end of the positioning post 41 is press-fitted with the heating wire assembly 30 and rotates with the mouthpiece 10. The sealing sleeve 42 fits tightly against the positioning post 41 and the chamber 20, effectively preventing minute leakage of e-liquid and maintaining good sealing performance. The positioning post 41 serves as the rotational transmission mechanism between the mouthpiece 10 and the heating wire assembly 30, ensuring that the heating wire assembly 30 rotates synchronously when the mouthpiece 10 rotates, and guaranteeing precise switching of the relative positions of the oil inlet 31 and the oil inlet groove 52. The sealing sleeve 42 fits snugly against the inner wall of the chamber 20, and through its own elasticity, applies radial clamping pressure towards the positioning post 41 during the natural recovery process after assembly. This ensures that the sealing sleeve 42 maintains tight contact with the positioning post 41 under different operating conditions, forming a radial seal and preventing oil or atomized smoke in the oil storage chamber 21 from leaking from the opening of the chamber 20, thus improving sealing reliability. The sealing sleeve 42 and sealing seat 50 can be made of silicone.
[0039] As one implementation method, such as Figure 9 and Figure 10As shown, the top of the positioning post 41 is provided with a first positioning structure 411, and the bottom of the mouthpiece 10 is provided with a second positioning structure 11 that cooperates with the first positioning structure 411. With the cooperation of the first positioning structure 411 and the second positioning structure 11, the positioning post 41 rotates with the mouthpiece 10. Specifically, the top of the positioning post 41 is provided with a first positioning structure 411 (such as a protrusion or groove), and the bottom of the mouthpiece 10 is provided with a second positioning structure 11 (such as a groove or protrusion) that is adapted to the first positioning structure 411. For example, after the cooperation of the protrusion on the positioning post 41 and the groove on the mouthpiece 10, the positioning post 41 rotates synchronously with the mouthpiece 10. Through the mechanical cooperation of the first positioning structure 411 and the second positioning structure 11, the relative rotational gap between the positioning post 41 and the mouthpiece 10 is eliminated, ensuring that the rotational transmission is lag-free and guaranteeing the alignment or misalignment accuracy of the oil inlet hole 31 and the oil inlet groove 52.
[0040] As one implementation, a rotation positioning structure is provided at the connection between the mouthpiece 10 and the housing 20 to limit the rotation angle of the mouthpiece 10 and achieve positioning after rotation.
[0041] As one implementation method, such as Figure 9 and Figure 12 As shown, the rotary positioning structure includes a rotating rod 12 and a rotating groove 22 that cooperate with each other. The rotating rod 12 is located at the bottom of the mouthpiece 10, and the rotating groove 22 is located at the top of the chamber 20. The inner wall of the rotating groove 22 is provided with multiple positioning protrusions 23 along the circumference. The rotating rod 12 is inserted into the rotating groove 22. The positioning protrusions 23 and the outer wall of the rotating rod 12 form a damping fit. When a preset external force is applied (such as when rotating manually), the rotating rod 12 can overcome the resistance and rotate. When subjected to only slight shaking, the positioning protrusions 23 restrict the rotation of the rotating rod 12, effectively preventing accidental changes in the oil circuit state and improving the safety of use. At the same time, the positioning protrusions 23 provide staged rotational resistance, so that the user can get a clear sense of the gear when rotating the mouthpiece 10, making it easy to judge the oil circuit status. Specifically, the rotating groove 22 is an arc-shaped groove coaxial with the positioning post 41. The degree of the central angle of the arc-shaped groove can be set to 20°, 30°, 45° or 60° (preferably 30°), which is used to limit the maximum rotation angle of the rotating rod 12, that is, the preset angle mentioned above is equal to the central angle. Of course, the rotating groove 22 can also be set at the bottom of the mouthpiece 10 and the rotating rod 12 can be set at the top of the compartment 20.
[0042] As one implementation method, such as Figure 2 and Figure 9As shown, the bottom of the mouthpiece 10 is provided with at least two connecting parts 13. The connecting parts 13 include connecting rods 131 and barbs 132 connected to each other. The bottom of each barb 132 is provided with a guide surface 1321 that is inclined from the mouthpiece 10 to the oil storage cavity 21. The guide surface 1321 is used to guide the barb 132 to slide into the chamber 20. The connecting rod 131 is inserted into the chamber 20, and the barb 132 is hooked on the top wall of the chamber 20 to achieve axial fixation between the mouthpiece 10 and the chamber 20, preventing the mouthpiece 10 from falling off the chamber 20, while not affecting the circumferential rotation of the mouthpiece 10. The guide surface 1321 reduces the assembly difficulty, allowing the barb 132 to slide into the chamber 20 through elastic deformation and automatically hook, improving production assembly efficiency. Multiple connecting parts 13 are evenly distributed circumferentially to ensure that the mouthpiece 10 is subjected to balanced force and avoid tilting or jamming caused by loosening on one side.
[0043] As one implementation method, such as Figure 9 and Figure 10 As shown, the sealing connector 40 has a clearance groove 412 corresponding to the connecting part 13, and the barbs 132 pass through the clearance groove 412 one by one and hook onto the top wall of the compartment 20. Specifically, the outer wall of the positioning post 41 has clearance grooves 412 that correspond one-to-one with the connecting part 13 along the axial direction, so that the clearance grooves 412 provide clearance space for the barbs 132, avoiding structural interference between the positioning post 41 and the connecting part 13, ensuring that the two can be assembled at the same time. The connecting rod 131 is accommodated in the clearance groove 412, and the barbs 132 are hooked onto the inner wall of the compartment 20. The positioning post 41 and the connecting part 13 are compactly distributed, reducing the overall structural volume.
[0044] As one implementation method, such as Figure 8 and Figure 11 As shown, the inner wall of the sealing seat 50 is provided with multiple oil inlet grooves 52 along the circumference, and the lower end of the heating wire assembly 30 is provided with multiple oil inlet holes 31 along the circumference. The included angle between two adjacent oil inlet grooves 52 is equal to the included angle between two adjacent oil inlet holes 31. When the mouthpiece 10 rotates to a preset angle, the oil inlet hole 31 and the oil inlet groove 52 can be completely aligned with the maximum oil intake or completely misaligned to completely seal the oil, avoiding oil leakage or insufficient oil supply caused by partial alignment. The design of multiple oil inlet grooves 52 and oil inlet holes 31 increases the oil flow area, improves the oil supply efficiency, and ensures the stable atomization effect of the heating wire assembly 30. The circumferential uniform distribution ensures that the oil is evenly distributed when it enters the heating wire assembly 30, reducing local oil accumulation or drying.
[0045] For example, the inner wall of the sealing seat 50 is evenly provided with 6 oil inlet grooves 52 along the circumference (the included angle between two adjacent grooves is 60°), and the bottom of the heating wire assembly 30 is evenly provided with 6 oil inlet holes 31 along the circumference (the included angle between two adjacent holes is 60°). When each oil inlet groove 52 corresponds one-to-one with each oil inlet hole 31, the oil passage is opened; if the cigarette holder 10 is rotated clockwise by a preset angle of 30° (e.g. Figure 3As shown), rotate the nozzle 10 until it is rotated to the midpoint where the angle between the oil inlet 31 and the adjacent oil inlet groove 52 is 30°, thus closing the oil passage. When using the nozzle, rotate it counterclockwise by the preset angle of 30° (as shown). Figure 1 As shown), the oil circuit is open.
[0046] As one implementation method, such as Figure 1 , Figure 2 , Figure 8 and Figure 12 As shown, the rotary sealing structure also includes a chamber cover 60, which includes a gasket 61 and a plug 62 connected to each other. The top of the chamber 20 has an oil filling hole 24, which is sealed by the plug 62. The gasket 61 is sandwiched between the mouthpiece 10 and the chamber 20. In this embodiment, the plug 62 seals the oil filling hole 24, thus sealing the oil storage chamber 21 and preventing oil leakage after filling. The gasket 61, sandwiched between the mouthpiece 10 and the chamber 20, enhances the sealing at the connection point and reduces direct friction during rotation, thus reducing wear and noise. The chamber cover 60 is removable, allowing users to easily replenish oil through the oil filling hole 24, improving the product's reusability. The gasket 61 and the plug 62 are an integral structure; when the plug 62 is removed for oil filling, it remains on top of the chamber 20 and is not easily dislodged (a separately installed plug 62 is prone to falling off). The cover 60 is marked with an arrow to remind the user of the direction to turn the mouthpiece 10 when shutting off the oil circuit.
[0047] This utility model also provides an electronic cigarette, such as Figures 1 to 4 As shown, it includes the rotary oil sealing structure described above.
[0048] As one implementation method, such as Figure 1 and Figure 2 As shown, the electronic cigarette also includes a housing 70 and a bracket 80. The bracket 80 is installed inside the housing 70, and a first cavity 71 is formed between the bracket 80 and the top of the housing 70. A rotating oil sealing structure is installed inside the first cavity 71, and the sealing seat 50 is fixedly connected to the bracket 80. The mouthpiece 10 protrudes outside the housing 70 for easy rotation and inhalation.
[0049] As one implementation method, such as Figure 2 , Figure 7 and Figure 8As shown, the electronic cigarette also includes a PCBA board 90, a microphone assembly 100, and a battery 110. A second cavity 72 is formed between the bracket 80 and the bottom of the outer shell 70. The PCBA board 90, microphone assembly 100, and battery 110 are installed in the second cavity 72, and the PCBA board 90 and microphone assembly 100 are fixed in relative position by the bracket 80. A sealing piece 130 (such as a silicone sheet) is sandwiched between the microphone assembly 100 and the inner wall of the outer shell 70. By filling the gap and generating a pre-tightening force, the radial and axial displacement of the microphone assembly 100 is restricted. Among them, the PCBA board 90 is the control center; the microphone assembly 100 is an airflow sensing element used to trigger atomization; and the battery 110 provides electrical energy. The bottom of the outer casing 70 is provided with an air inlet (not shown), and the bracket 80, sealing seat 50, and positioning post 41 are all provided with vents (not shown), allowing airflow to pass sequentially through the vents of the bracket 80 and the sealing seat 50, and then through the atomization area of the heating wire assembly 30. The airflow mixes thoroughly with the e-liquid heated and atomized by the heating wire to form smoke that can be inhaled. The smoke flows through the air guide tube of the heating wire assembly 30 to the vent of the positioning post 41, and then reaches the mouthpiece 10. The specific structure of the heating wire assembly 30 can be found in existing technology and will not be described here.
[0050] The specific atomization process is as follows: When a user inhales through the mouthpiece 10, the airflow entering from the bottom air inlet of the outer shell 70 flows sequentially through the vent holes of the bracket 80 and the sealing seat 50, finally reaching the atomization area of the heating wire assembly 30. Simultaneously, the PCBA board 90 receives the inhalation signal transmitted by the airflow sensing element of the microphone assembly 100, controlling the battery 110 to supply power to the heating wire assembly 30, causing the heating wire to rapidly heat up to the e-liquid atomization temperature. The oil storage chamber 21 delivers e-liquid to the heating wire assembly 30 through the conductive oil inlet groove 52 and oil inlet hole 31. Upon contact with the high-temperature heating wire, the e-liquid is instantly heated and vaporized, forming tiny smoke particles. These smoke particles are thoroughly mixed with the flowing airflow to form a uniform aerosol. Subsequently, the mixed airflow carries the smoke through the air guide tube of the heating wire assembly 30 and the vent holes of the positioning post 41, finally entering the user's mouth through the mouthpiece 10, completing the entire atomization and inhalation process.
[0051] As one implementation method, such as Figure 2 , Figure 7 and Figure 8 As shown, the electronic cigarette also includes a lens 120 mounted on the outer wall of the housing 70. The lens 120 is usually made of a transparent / semi-transparent material, such as acrylic or glass, and is mounted on the outer wall of the housing 70 to cover the internal indicator lights (such as power indicator and working status indicator). It achieves external display of light signals through light transmission, while isolating external dust and moisture.
[0052] This invention achieves active control of the oil circuit between the oil storage chamber 21 and the heating wire assembly 30 by rotating the mouthpiece 10. The "open" and "closed" states of the oil circuit can be switched by mechanical rotation, solving the problem of oil leakage caused by long-term continuous oil circuit in traditional structures. It effectively reduces the occurrence of oil leakage and achieves reliable e-liquid sealing. Furthermore, the outer wall of the sealing connector 40 fits against the inner wall of the chamber 20, forming a radial seal at the opening of the chamber 20, preventing e-liquid or atomized smoke in the oil storage chamber 21 from leaking from the opening gap, further improving the sealing performance of the device.
[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
