Description

Technical Field

[0001] This utility model relates to the field of electronic atomization device technology, and in particular to a gas-sealing and oil-sealing rotating structure. Background Technology

[0002] Electronic atomizing devices, which convert liquid into vapor through heating for inhalation, rely heavily on the sealing of their internal oil reservoir and the unobstructed flow of air through their airflow channels to ensure optimal user experience. Currently, most electronic atomizing devices have their oil and airflow channels designed to be normally open, or while they may offer some adjustment, their structures are often fragmented and complex. This makes it easy for liquid in the reservoir to seep into the atomizer coil and leak out through the airflow vents when the device is stored for extended periods or carried around in a non-operating state. Changes in ambient temperature, air pressure, or violent shaking can cause this, or for external air to flow back into the reservoir, leading to e-liquid oxidation and deterioration. Existing technologies struggle to reliably block both the oil and airflow channels simultaneously through simple, single mechanical mechanisms, and lack effective mechanisms to prevent accidental activation and ensure proper rotation, resulting in low product reliability and portability safety.

[0003] Therefore, this utility model proposes a rotating structure for sealing air and oil to overcome the shortcomings of the prior art. Utility Model Content

[0004] In view of the problems in the existing technology, electronic atomizing devices cannot simultaneously and effectively seal the oil and air circuits when not in operation, which can easily lead to e-liquid leakage or air backflow. In addition, the existing adjustment mechanism is complex in structure, cumbersome in operation, and lacks clear feedback on switch position and limit protection. This utility model aims to provide a rotary structure with improved structure that can effectively solve the above problems of sealing air and oil.

[0005] This utility model provides a rotating structure for sealing air and oil, including: a bottom support, an oil tank fixed on the bottom support, and a lower sealing silicone installed in the bottom support; and a rotating component rotatably disposed in the oil tank.

[0006] The rotating assembly includes a metal steel pipe as the core support frame, an upper fixing member and a lower fixing member respectively fixed to both ends of the metal steel pipe, and an atomizing assembly housed in the internal cavity of the metal steel pipe.

[0007] Furthermore, the upper fixing member has a sealing silicone on top and an oil sealing silicone on its outer periphery. The outer wall of the oil sealing silicone is tightly sealed to the inner wall of the oil tank to form a dynamic sealing interface. A cigarette holder is inserted into the top opening of the oil tank. The bottom of the cigarette holder has a rib. The top of the upper fixing member has a rib groove. The rib is inserted into the rib groove and drives the rotating component to rotate relative to the oil tank. The bottom of the rotating component rotates and abuts against the lower sealing silicone. The rotation of the cigarette holder drives the rotating component to rotate inside the oil tank, thereby changing the relative position of the internal channels.

[0008] Preferably, in order to achieve reliable on / off control of the oil circuit, the side wall of the metal pipe is provided with a steel pipe oil inlet hole, and the lower sealing silicone protrudes towards the side of the metal pipe to form a lower sealing oil-sealing step; when the rotating component is rotated to the closed state, the steel pipe oil inlet hole is directly opposite the lower sealing oil-sealing step and is blocked by its surface; when the rotating component is rotated to the working state, the steel pipe oil inlet hole and the lower sealing oil-sealing step are misaligned, so that the liquid in the oil tank can flow into the atomizing component through the steel pipe oil inlet hole.

[0009] Preferably, in order to achieve synchronous adjustment of the air path, the bottom bracket has a first air inlet hole at the bottom, the lower sealing silicone has a second air inlet hole corresponding to the position of the first air inlet hole, and the lower fixing member has a third air inlet hole at the bottom; when the rotating assembly rotates to the working state, the first air inlet hole, the second air inlet hole and the third air inlet hole are interconnected to form a complete air intake channel.

[0010] Preferably, in order to prevent excessive rotation from damaging the internal structure, an oil tank limiting groove is provided on the inner wall of the oil tank, and the insert part extends outward and into the oil tank limiting groove. The rotation angle range of the rotating component is limited by the physical contact between the side of the insert and the side wall of the oil tank limiting groove.

[0011] Preferably, in order to prevent the mouthpiece from accidentally falling off, the outer wall of the mouthpiece is provided with a buckle, and the inner wall of the top opening of the oil tank is provided with a buckle groove. The buckle is engaged in the buckle groove, and the structural interference restricts the axial dislodgement of the mouthpiece.

[0012] Preferably, in order to provide a good operating feel and gear position fixation, a rotation feel structure is provided between the mating surfaces of the rotating component and the bottom bracket. The rotation feel structure includes a slot formed in the inner wall of the bottom bracket and a boss provided in the outer wall of the lower fixing member. The boss is an elastic structure. When the rotating component rotates, the boss is compressed and deformed and slides into or out of the slot, thereby providing clear tactile feedback and gear position fixation.

[0013] Preferably, in order to ensure the rigidity of the rotating component connection, symmetrical strip grooves are provided on the upper and lower ends of the metal steel pipe. The upper fixing member and the lower fixing member are fixed to the strip grooves by a strong pressure fit to ensure that the entire component rotates coaxially without loosening.

[0014] Preferably, in order to achieve sealed lead-out of the internal circuit, a wire hole is also provided at the bottom of the bottom bracket. After the heating wire of the atomizing component passes through the lower fixing member and the reserved channel of the lower sealing silicone, it passes through the wire hole and is fixed and sealed by the glue dispensing process.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting up a cooperative structure of rotating and fixed components, the mouthpiece drives the internal metal steel pipe and atomizing component to rotate as a whole, causing the oil inlet of the steel pipe to be misaligned or aligned with the oil-sealing step of the lower seal, and simultaneously causing the bottom air inlet to be misaligned or connected. This solves the problem of existing electronic atomizing devices having the oil and air circuits constantly open when not in use, leading to easy leakage, or requiring complex step-by-step operations for oil and air adjustment. It achieves the effect of reliably adjusting the oil and air circuits simultaneously with a single rotation action, effectively preventing e-liquid leakage and air backflow during storage, and improving the product's portability, safety, and ease of use.

[0017] 2. In this utility model, a metal steel pipe is used as the core support frame, and strip grooves are opened at both ends to be assembled with the upper and lower fixing parts by interference fit. This solves the problem that the traditional multi-part splicing structure is prone to relative displacement, loosening and deformation during frequent rotation, resulting in misalignment of holes. It achieves the technical effect of enhancing the rigidity and coaxiality of the overall rotating structure, ensuring that the oil inlet and air inlet maintain precise alignment during long-term use, thereby ensuring stable and reliable sealing and oil guiding performance.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example:

[0026] Please refer to Figures 1 to 4 This utility model provides a rotating structure for sealing air and oil, which aims to solve the problems of complex oil and air circuit control, poor sealing reliability, and difficulty in achieving synchronous adjustment through a single action in the prior art of electronic atomizing devices.

[0027] like Figure 1 As shown, the air-sealing and oil-sealing rotary structure includes a bottom bracket 7 as an integral mounting base, an oil tank 16 fixedly connected to the top of the bottom bracket 7, and a lower sealing silicone 6 that is interference-fitted and installed at the bottom of the bottom of the bottom bracket 7. After the bottom bracket 7 and the oil tank 16 are fixedly connected, a stationary component with a receiving space is formed. The lower sealing silicone 6 is located at the bottom of the receiving space to form a sealing and mating interface at the bottom.

[0028] A rotating assembly is rotatably installed in the internal cavity formed by the oil tank 16 and the bottom support 7. The rotating assembly extends to the lower sealing silicone 6 and forms a rotational seal with its top surface. The core support frame of the rotating assembly is a metal steel pipe 4, which is vertically installed at the axis of the oil tank 16. The top of the metal steel pipe 4 is connected to the upper fixing member 2 by a jig with a strong pressure interference fit, and the bottom of the metal steel pipe 4 is connected to the lower fixing member 5 by a jig with a strong pressure interference fit. The upper fixing member 2 and the lower fixing member 5 are respectively fixedly connected to the upper and lower ends of the metal steel pipe 4 to form a rigid rotating whole. The atomizing assembly 23 is housed and fixed in the internal cavity of the metal steel pipe 4 for heating and atomizing the flowing liquid.

[0029] A sealing silicone 3 is press-fitted onto the top of the upper fixing part 2. The sealing silicone 3 is tightly pressed onto the top end of the metal steel pipe 4 to form a top airtight device. An oil sealing silicone 17 is sleeved on the outer periphery of the upper fixing part 2. The outer wall of the oil sealing silicone 17 is interference-fitted with the inner wall of the oil tank 16. During the rotation of the rotating component, the oil sealing silicone 17 always maintains close contact with the inner wall of the oil tank 16 to form a dynamic sealing structure, preventing the liquid in the oil tank 16 from leaking from the top gap.

[0030] A mouthpiece 1 for user inhalation and operation is inserted into the top opening of the oil tank 16. The bottom of the mouthpiece 1 is integrally formed or fixedly provided with a rib 20. The top end face of the upper fixing member 2 has a bone groove 21 with a shape matching the rib 20. The rib 20 is inserted downward into the bone groove 21 to realize the circumferential fixed linkage between the mouthpiece 1 and the upper fixing member 2. When an external force is applied to the mouthpiece 1 to make it rotate, the mouthpiece 1 drives the upper fixing member 2, the metal steel pipe 4, the lower fixing member 5 and the atomizing component 23 to rotate synchronously relative to the oil tank 16 and the lower sealing silicone 6 through the rib 20, thereby realizing the switching and adjustment of the internal air passage and oil passage on / off state.

[0031] To address the aforementioned technical issues regarding the complexity of oil and gas circuit control and unreliable sealing, please refer to the following: Figure 1 , Figure 3 and Figure 4 As a core fluid channel control component, a steel pipe oil inlet hole 14 is provided through the side wall of the metal steel pipe 4. The steel pipe oil inlet hole 14 directly connects the oil storage space inside the oil tank 16 and the chamber where the atomizing component 23 is located inside the metal steel pipe 4. The lower sealing silicone 6 has an integrally formed lower sealing oil sealing step 15 protruding on the side surface facing the outer wall of the metal steel pipe 4. The lower sealing oil sealing step 15 has an arc-shaped fitting surface that is adapted to the outer circumferential surface of the metal steel pipe 4.

[0032] In terms of airflow channel construction, a first air inlet 11 is provided through the bottom wall of the bottom bracket 7, a second air inlet 12 is provided at the corresponding position of the lower sealing silicone 6 installed in the bottom bracket 7, and a third air inlet 13 is provided on the bottom surface of the lower fixing member 5. The first air inlet 11, the second air inlet 12 and the third air inlet 13 together constitute the breathing channel for external air to enter the atomizing component 23. The lower sealing silicone 6 is fixed in the bottom bracket 7 and does not move, while the lower fixing member 5 rotates together with the metal steel pipe 4, thereby changing the circumferential position of the third air inlet 13 relative to the second air inlet 12.

[0033] By rotating the nozzle 1, the rotating component can be driven to rotate, which can realize the synchronous on / off control of the oil circuit and the air circuit. When the rotating component rotates to the closed position, the oil inlet hole 14 of the steel pipe rotates to the position directly opposite the lower sealing oil sealing step 15. The lower sealing oil sealing step 15 uses the elasticity of the silicone material to tightly cover the surface of the oil inlet hole 14 of the steel pipe to physically isolate the oil circuit and prevent the liquid in the oil tank 16 from seeping into the atomizing component 23 and causing leakage. At the same time, the third air inlet hole 13 on the lower fixing part 5 and the second air inlet hole 12 on the lower sealing silicone 6 are misaligned, and the bottom air inlet channel is sealed to prevent air backflow or condensate leakage.

[0034] When the equipment is needed, the rotating component is rotated to the working position. At this time, the oil inlet 14 of the steel pipe rotates circumferentially and avoids the blocking area of ​​the lower sealing oil step 15. The oil inlet 14 of the steel pipe is misaligned with the lower sealing oil step 15. The oil in the oil tank 16 flows smoothly into the atomizing component 23 through the oil inlet 14 of the steel pipe for oil guiding. At the same time, the third air inlet 13 of the lower fixing part 5 rotates to be aligned and connected with the second air inlet 12 of the lower sealing silicone 6 and the first air inlet 11 of the bottom bracket 7 in the vertical direction. The outside air smoothly enters the atomizing component 23 to participate in the atomization process.

[0035] In addition, in order to ensure the stability and alignment accuracy of the connection of each component during rotation, symmetrically arranged strip grooves are opened on the upper and lower ends of the metal steel pipe 4. The upper fixing part 2 and the lower fixing part 5 use the strip groove structure to achieve high-strength interference fit through the strong pressure of the fixture, ensuring that there is no relative displacement between the metal steel pipe 4 and the upper and lower fixing parts under frequent rotation operation, thereby ensuring the alignment accuracy of the air hole and the oil hole.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0037] As a preferred embodiment, to prevent excessive rotation of the rotating component from causing internal wiring breakage or structural misalignment, please refer to... Figure 2 and Figure 4 The inner wall of the top of the oil tank 16 is recessed and has an oil tank limiting groove 22. The insert 20 at the bottom of the mouthpiece 1 or part of the upper fixing member 2 extends outward and enters the internal space of the oil tank limiting groove 22. The oil tank limiting groove 22 has two limit abutment side walls in the circumferential direction. When the rotating component is subjected to force and rotates to the preset maximum allowable angle, the side of the insert 20 directly abuts the side wall of the oil tank limiting groove 22. This rigid limiting action precisely limits the effective rotation range of the rotating component.

[0038] As another preferred embodiment, to address the issue that the mouthpiece 1 is prone to accidental detachment during frequent operation, please refer to... Figure 4The outer wall of the mouthpiece 1 has a circumferential protrusion with a ring-shaped or segmented buckle 18. The inner wall of the top opening of the oil tank 16 has a corresponding recessed groove 19. During the assembly process of inserting the mouthpiece 1 into the oil tank 16, the buckle 18 undergoes a slight deformation due to the elasticity of the material itself and then embeds into the groove 19. The axial stop of the upper end face of the buckle 18 and the upper side wall of the groove 19 effectively restricts the mouthpiece 1 from coming out axially, ensuring the connection is stable.

[0039] As a further preferred embodiment, in order to provide the user with clear feedback on the position and a feel for maintaining the gear during rotation adjustment, please refer to... Figure 1 A rotating tactile structure is provided between the outer wall of the lower fixing member 5 at the bottom of the rotating component and the inner wall of the bottom support 7. This structure specifically includes a slot 8 opened in the inner wall of the bottom support 7 and a boss 9 protruding from the outer wall of the lower fixing member 5. The boss 9 is designed as a protruding structure with a certain elasticity. During the rotation of the rotating component, the boss 9 is compressed and deformed and slides over the surface of the inner wall of the bottom support 7. When the rotating component reaches the preset open or closed position, the boss 9 uses elastic potential energy to rebound and slide into the slot 8, generating obvious tactile feedback and providing a certain circumferential positioning and holding force for the rotating component.

[0040] In addition, please refer to the wiring layout for internal electrical connections. Figure 3 The bottom bracket 7 has a through hole 10. The heating wire of the atomizing component 23 passes through the channel reserved by the lower fixing part 5 and the lower sealing silicone 6, and finally leads out to the outside area of ​​the bottom bracket 7 through the through hole 10. The wire is sealed and fixed at the through hole 10 by the glue dispensing process, which not only ensures the overall sealing performance of the bottom, but also effectively prevents the wire from loosening or breaking due to force.

[0041] Working principle: When the electronic atomizing device is needed, the user pinches the mouthpiece 1 with their fingers and applies rotational torque. The mouthpiece 1 transmits the rotational torque to the upper fixing component 2 through the tight insertion and engagement of the bottom insert 20 with the top groove 21 of the upper fixing component 2. Since the upper fixing component 2, the metal steel pipe 4 and the lower fixing component 5 are connected into a rigid whole by a strong pressure interference fit, the mouthpiece 1 drives the entire rotating assembly to start rotating synchronously relative to the external stationary oil tank 16 and the bottom support 7. During this process, the elastic protrusion 9 on the outer wall of the lower fixing component 5 is deformed by pressure and slides out of the slot 8 on the inner wall of the bottom support 7, providing the user with a clear tactile feedback of rotation start.

[0042] As the rotating component rotates to the preset working angle, the oil inlet hole 14 of the steel pipe on the side wall of the metal steel pipe 4 moves circumferentially and leaves the coverage area of ​​the upper and lower sealing oil sealing steps 15 of the lower sealing silicone 6. The oil inlet hole 14 of the steel pipe and the lower sealing oil sealing steps 15 are misaligned. The liquid stored inside the oil tank 16 flows smoothly into the metal steel pipe 4 through the oil inlet hole 14 of the steel pipe and is absorbed by the atomizing component 23. At the same time, the third air inlet hole 13 at the bottom of the lower fixing part 5 rotates to a position that is vertically aligned with the second air inlet hole 12 on the lower sealing silicone 6 and the first air inlet hole 11 on the bottom bracket 7. Under the action of negative pressure, the external air passes through the first air inlet hole 11, the second air inlet hole 12 and the third air inlet hole 13 in sequence and enters the atomizing component 23 to participate in the atomization process. At this time, the equipment is in a working state with both oil and air passages open.

[0043] When the device is finished and needs to be stored, the user rotates the mouthpiece 1 in the opposite direction. The insert 20 moves within the oil tank limiting groove 22 until it is blocked by the side wall and stops. At this time, the boss 9 slides into the slot 8 again and locks in the position. The metal pipe 4 drives the oil inlet hole 14 of the steel pipe to rotate to the position directly opposite the lower sealing oil sealing step 15. The lower sealing oil sealing step 15 uses the elasticity of silicone to tightly seal and block the oil inlet hole 14 of the steel pipe, physically cutting off the oil flow path to prevent leakage. Simultaneously, the lower fixing part 5 drives the third air inlet hole 13 to rotate to the position that is misaligned with the second air inlet hole 12. The bottom air inlet channel is blocked by the solid part of the lower sealing silicone 6, realizing the air path sealing. During the entire rotation switching process, the atomizing component 23 and its connecting lead rotate synchronously with the metal pipe 4, effectively avoiding the risk of internal circuits getting tangled or broken due to relative torsion.

[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes 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 protection scope of the claims.
