The isolation tube is installed inside the housing, forming a liquid storage chamber between the isolation tube and the housing for storing liquid. The atomizing coil passes through the bottom of the housing and extends into the isolation tube, and is slidably connected to the isolation tube.

Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to an atomizing device that is easy to assemble and disassemble the atomizing core. Background Technology

[0002] When replacing the atomizer coil in the liquid-filled state of existing atomizing devices, liquid leakage is prone to occur because the liquid-filled chamber and the atomizer coil installation area are directly connected. Users need to empty the liquid-filled chamber before replacing the atomizer coil, which is cumbersome and wastes liquid. Although some devices have attempted to optimize the sealing structure, they still cannot balance the convenience of coil replacement and the reliability of leak prevention in the liquid-filled state. They have defects such as leakage during coil replacement, complicated operation, or easy damage to parts, which affect the user experience and the practicality of the device. Utility Model Content

[0005] In one embodiment, the atomizing core includes a heating element, an atomizing tube, and a first base; a second base is provided at the bottom of the housing; the heating element is installed inside the atomizing tube, and the bottom of the atomizing tube is connected to the first base; the atomizing tube is installed inside the isolation tube and slidably connected to the isolation tube, and a second liquid inlet is provided corresponding to the first liquid inlet; the first base partially extends into the second base, partially extends out of the second base, and is detachably connected to the second base.

[0006] In one embodiment, the bottom of the first base is provided with a first flange, and when the atomizing tube is installed in the isolation tube, the first flange abuts against the lower surface of the second base.

[0007] In one embodiment, the bottom of the first base is further provided with a second flange, and the lower surface of the second base is provided with a groove. When the atomizing tube passes through the second base and is installed in the isolation tube, both the first flange and the second flange are located in the groove, and the first flange abuts against the inner surface of the groove, and the second flange forms a gap with the inner surface of the groove.

[0008] In one embodiment, a first sealing seat arranged in a ring is installed on the inner side of the second base, and the upper surface of the first sealing seat is lower than the first liquid inlet. The bottom of the isolation tube is connected to the first sealing seat, and the outer surface of the bottom of the atomizing tube abuts against the inner surface of the first sealing seat.

[0009] In one embodiment, the inner surface of the first sealing seat extends inwardly with a third flange, the outer surface of the bottom of the isolation tube abuts against the inner surface of the first sealing seat, the upper and lower surfaces of the third flange abut against the isolation tube and the second base respectively, and the third flange is interference-fitted with the atomizing core.

[0010] In one embodiment, a mist outlet tube extends inward from the top of the housing, and the atomizing tube is connected to the mist outlet tube.

[0011] In one embodiment, the outer periphery of the mist outlet pipe is provided with a second sealing seat arranged in an annular shape, and the top of the isolation pipe is installed on the second sealing seat.

[0012] In one embodiment, an interface tube is connected to the top of the atomizing tube; one end of the interface tube extends into the atomizing tube and is connected to the atomizing tube, and the other end extends into the mist outlet tube, so that the mist outlet tube, the interface tube and the atomizing tube are connected in sequence.

[0013] In one embodiment, a sealing ring is provided between the interface tube, the mist outlet tube, and the isolation tube, and the sealing ring is embedded in the outer surface of the interface tube.

[0014] This invention provides an atomizing device with an easy-to-install and remove atomizing coil.

Combined with the sliding connection between the atomizing coil and the isolation tube, and utilizing the design where the liquid surface is lower than the first inlet when inverted, physical isolation is achieved between the liquid storage chamber and the interior of the isolation tube. Users do not need to empty the liquid storage chamber beforehand; simply inverting the device creates a liquid-free space for coil replacement, allowing direct sliding removal of the atomizing coil. This completely solves the core problem of leakage during coil replacement in existing devices with liquid storage. It eliminates the need for additional sealing valves or purging operations, simplifying the coil replacement process and avoiding liquid waste. Simultaneously, the sliding connection provides stable guidance for atomizing coil installation and removal, ensuring precise operation. This significantly improves the convenience, safety, and user experience of atomizing coil replacement. Furthermore, the overall structure is simple, easy to manufacture, and has low production costs.

[0026] See Figures 1 to 8 As shown, this utility model provides a specific embodiment of an atomizing device with an easy-to-disassemble and assemble atomizing core, including: a housing 1, an isolation tube 2, and an atomizing core 3; the isolation tube 2 is installed inside the housing 1, and a liquid storage chamber 4 is formed between the isolation tube 2 and the housing 1, the liquid storage chamber 4 being used to store liquid; the atomizing core 3 passes through the bottom of the housing 1 and extends into the isolation tube 2, and is slidably connected to the isolation tube 2; the lower section of the isolation tube 2 is provided with a first liquid inlet 21 communicating with the liquid storage chamber 4; when the atomizing device is inverted, the liquid surface in the liquid storage chamber 4 is lower than the first liquid inlet 21.

[0027] Specifically, this structural design allows the atomizing core 3 to slide along the isolation tube 2, while the first liquid inlet 21 is located at the lower section of the isolation tube 2. Under normal conditions, liquid can enter the isolation tube 2 from the storage chamber 4 through the first liquid inlet 21 to supply liquid to the atomizing core 3. However, in the inverted state, liquid cannot enter the isolation tube 2 area through the first liquid inlet 21, thus creating a liquid-free operating space physically isolated from the storage chamber 4, facilitating the axial sliding installation and removal of the atomizing core 3 along the isolation tube 2. This design utilizes the compatibility between liquid gravity and the inlet position to achieve switching between "normal liquid supply" and "safe core replacement" states without additional valves or sealing switches. When the user needs to remove or install the atomizing core 3, they only need to flip the device so that the liquid in the storage chamber 4 is below the first liquid inlet 21, and then directly pull out the atomizing core 3 to complete the removal. This completely avoids the risk of leakage during core replacement in the storage state. Simultaneously, the sliding connection provides a stable guide for the removal and installation of the atomizing core 3, ensuring precise and efficient operation.

[0028] Preferably, the housing 1 is made of transparent material in whole or in part, so that the remaining liquid volume in the liquid storage chamber 4 can be seen directly, making it convenient for users to replenish the liquid in time and avoid atomization interruption due to lack of liquid; combined with the characteristics of the device to replace the core, the transparent housing 1 can also help users to confirm whether the liquid surface is lower than the first liquid inlet 21, ensuring that the core replacement operation is carried out in an environment without liquid interference, further improving the convenience and safety of use.

[0029] In one specific embodiment, the atomizing core 3 includes a heating element 31, an atomizing tube 32, and a first base 33; a second base 11 is provided at the bottom of the housing 1; the heating element 31 is installed inside the atomizing tube 32, and the bottom of the atomizing tube 32 is connected to the first base 33; the atomizing tube 32 is installed inside the isolation tube 2 and slidably connected to the isolation tube 2, and a second liquid inlet 321 is provided corresponding to the first liquid inlet 21; the first base 33 partially extends into the second base 11, partially extends out of the second base 11, and is detachably connected to the second base 11.

[0030] Specifically, this design clearly defines the functions of each component of the atomizing core 3. The sliding fit between the atomizing tube 32 and the isolation tube 2 provides guidance for disassembly. The detachable connection between the first base 33 and the second base 11 enables quick assembly and disassembly of the atomizing core 3. The correspondence between the second liquid inlet 321 and the first liquid inlet 21 ensures that liquid can smoothly enter the atomizing tube 32 during normal use. This embodiment refines the structure of the atomizing core 3, improves the overall assembly precision of the atomizing device, and the detachable connection further simplifies the assembly and disassembly of the atomizing core 3 while ensuring the stability of the liquid supply under normal working conditions, thus balancing ease of assembly and disassembly with the reliability of the device.

[0031] Preferably, the top of the first base 33 extends into the atomizing tube 32 and is press-fitted with the atomizing tube 32 through the sealing element 35, which ensures the sealing and stability of the connection between the first base 33 and the atomizing tube 32. Thus, by applying force to the first base 33, the first base 33, along with the atomizing tube 32 and the heating element 31, can be pulled out simultaneously, while preventing liquid from leaking from the connection.

[0032] In one specific embodiment, the bottom of the first base 33 is provided with a first flange 331. When the atomizing tube 32 is installed in the isolation tube 2, the first flange 331 abuts against the lower surface of the second base 11.

[0033] Specifically, through the abutment action between the first flange 331 and the lower surface of the second base 11, on the one hand, it provides axial positioning for the atomizing core 3 in the installed state, precisely limiting the insertion depth of the atomizing core 3, and avoiding misalignment between the second liquid inlet 321 on the atomizing tube 32 and the first liquid inlet 21 of the isolation tube 2 due to excessive or shallow insertion; on the other hand, the first flange 331 provides a force application point for the user, making it easy to grasp or pry the first flange 331 to extract the atomizing core 3.

[0034] This design not only enhances the structural stability of the atomizer core 3 after installation, effectively preventing axial displacement of the atomizer core 3 during use and ensuring unobstructed liquid inlet channels, but also reduces the problem of poor atomization effect caused by displacement of the atomizer core 3. Furthermore, the limiting function ensures installation accuracy, and the flange structure facilitates disassembly, allowing the atomizer core 3 to be easily pulled out without the need for additional tools, further improving operational convenience. At the same time, the simple structure eliminates the need for additional complex components, reducing manufacturing costs.

[0035] In one specific embodiment, the bottom of the first base 33 is also provided with a second flange 332, and the lower surface of the second base 11 is provided with a groove 111. When the atomizing tube 32 passes through the second base 11 and is installed in the isolation tube 2, the first flange 331 and the second flange 332 are both located in the groove 111, and the first flange 331 abuts against the inner surface of the groove 111, and the second flange 332 forms a gap with the inner surface of the groove 111.

[0036] Specifically, the first flange 331 continues to serve as an axial limiting element, while the gap between the second flange 332 and the inner surface of the groove 111 provides space for the disassembly and assembly process. Users can apply external force through the gap to easily remove the first base 33 from the groove 111 of the second base 11. At the same time, the groove 111 provides radial positioning for the two flanges to prevent the atomizing core 3 from being misaligned during installation. The groove 111 can also accommodate the flange structure of the first base 33 to form a protective structure, preventing the first base 33 from directly colliding with the external structure.

[0037] This embodiment, while ensuring the stability of the atomizing core 3 during installation, further improves the ease of disassembly. The positioning function of the groove 111 allows the atomizing core 3 to be quickly and accurately positioned during installation, improving assembly efficiency. The gap also prevents jamming caused by excessive contact surface during disassembly, making the disassembly and assembly process of the atomizing core 3 smoother. At the same time, the protective function of the groove 111 effectively protects the first base 33 and its flange structure, reducing damage caused by external collisions, extending the service life of the atomizing core 3, and improving the overall durability of the device.

[0038] In one specific embodiment, a sealing ring 34 is embedded in the outer periphery of the portion of the first base 33 that extends into the second base 11, and the sealing ring 34 is interference-fitted with the second base 11.

[0039] Specifically, the interference fit sealing ring 34 can tightly fill the gap between the first base 33 and the second base 11 to form an effective sealing structure, preventing the liquid in the liquid storage chamber 4 from leaking out through the connection gap between the two. At the same time, the way the sealing ring 34 is embedded ensures that it is not easy to fall off during disassembly and assembly, and can maintain its sealing performance for a long time.

[0040] This design significantly improves the sealing performance of the connection between the first base 33 and the second base 11, completely eliminating the risk of leakage at this connection point. The setting of the sealing ring 34 does not affect the detachable connection between the two, achieving a balance between sealing performance and ease of disassembly and assembly, extending the service life of the atomizing device, and reducing liquid waste. In one specific embodiment, a first sealing seat 12 arranged in a ring is installed on the inner side of the second base 11, and the upper surface of the first sealing seat 12 is set lower than the first liquid inlet 21. The bottom of the isolation tube 2 is connected to the first sealing seat 12, and the outer surface of the bottom of the atomizing tube 32 abuts against the inner surface of the first sealing seat 12.

[0041] Specifically, the upper surface of the first sealing seat 12 is horizontally arranged and forms the lower cavity wall of the liquid storage chamber 4. The horizontal upper surface provides a stable bottom support for the liquid storage chamber 4. The connection between the isolation tube 2 and the first sealing seat 12 and the abutment between the atomizing tube 32 and the first sealing seat 12 make the first sealing seat 12 form a structural support between the isolation tube 2 and the second base 11. The design of the upper surface being lower than the first liquid inlet 21 avoids the accumulation of liquid in the sealing part under normal conditions. At the same time, the abutment relationship between the bottom of the atomizing tube 32 and the first sealing seat 12 can not only provide bottom support and axial limit for the atomizing core 3, but also, when the atomizing core 3 is pulled out, the inner surface of the first sealing seat 12 can scrape off the liquid attached to the outer periphery of the atomizing tube 32. The scraped liquid can be stored in the isolation tube 2 and flow back to the liquid storage chamber 4 through the first liquid inlet 21. This not only enhances the overall structural stability of the bottom of the atomizing device, but also realizes the liquid recovery function during the coil removal process. The scraped liquid flows back to the liquid storage chamber 4 to avoid liquid leakage and waste, keeps the outer wall of the atomizing tube 32 clean, and improves the cleanliness of the coil replacement process. At the same time, the abutting fit takes into account both the positioning requirements of the atomizing coil 3 and the convenience of disassembly and assembly.

[0042] In one specific embodiment, the inner surface of the first sealing seat 12 extends inward with a third flange 121, the outer surface of the bottom of the isolation tube 2 abuts against the inner surface of the first sealing seat 12, the upper and lower surfaces of the third flange 121 abut against the isolation tube 2 and the second base 11 respectively, and the third flange 121 is interference-fitted with the atomizing core 3.

[0043] Specifically, the third flange 121 forms an axial limiting structure by abutting the isolation tube 2 and the second base 11 on its upper and lower surfaces, respectively. The isolation tube 2 and the second base 11 together support the third flange 121 to prevent it from undergoing axial deformation under stress. At the same time, the third flange 121 provides axial support and positioning for the isolation tube 2, strengthens the connection stability between the isolation tube 2 and the first sealing seat 12, and the interference fit design between the third flange 121 and the atomizing core 3 has dual adaptability: during normal use, the clamping force forms a radial constraint to prevent the atomizing tube 32 from shifting; during insertion and removal, the annular narrow surface contact reduces frictional resistance, and as a core structure, it scrapes and recovers the liquid around the atomizing tube 32, forming a multi-layer seal with the body of the first sealing seat 12.

[0044] This design optimizes the integrated function of the first sealing seat 12. The support of the isolation tube 2 and the second base 11 prevents axial deformation of the third flange 121, ensuring structural strength and functional stability, and avoiding sealing failure or positioning deviation. The third flange 121 enables precise positioning of the isolation tube 2, solving the shaking problem. The interference fit balances stability and smooth disassembly and assembly requirements, reducing component wear. Furthermore, the third flange 121 serves as the core to achieve liquid scraping and recovery. Combined with multiple seals, this comprehensively improves the sealing reliability, structural strength, and ease of core replacement of the device.

[0045] In one specific embodiment, a mist outlet pipe 13 extends inward from the top of the housing 1, and the top of the atomizing pipe 32 is connected to the mist outlet pipe 13.

[0046] Specifically, the mist outlet pipe 13 serves as the discharge channel for the atomized gas. Its connection to the top of the atomizing tube 32 ensures that the mist generated by atomization can be smoothly discharged from the inside of the device. The inward-extending structural design brings the mist outlet pipe 13 closer to the top of the atomizing tube 32, shortening the mist transmission path and reducing mist residue inside the device. This design achieves effective mist discharge from the atomizing device, shortens the mist transmission distance, reduces mist loss, and improves atomization efficiency. At the same time, the integrated design of the mist outlet pipe 13 makes the top structure of the device more compact, reduces external pipe connections, and improves the aesthetics and portability of the device.

[0047] In one specific embodiment, a plug 15 is inserted into the mist outlet pipe 13, which can seal the mist outlet pipe 13 when the device is idle or during transportation, preventing external dust and impurities from entering and contaminating the atomizing core 3 and other components, and also preventing residual liquid in the isolation tube 2 from leaking from the mist outlet pipe 13; at the same time, it can protect the mist outlet pipe 13, reduce bumps and wear, and the plug-in structure is easy to disassemble and assemble, does not affect the mist output during normal use, and improves the reliability of the device during storage and transportation.

[0048] In one specific embodiment, a second sealing seat 14 arranged in a ring is provided on the outer periphery of the mist outlet pipe 13, and the top of the isolation pipe 2 is installed on the second sealing seat 14.

[0049] Specifically, the second sealing seat 14 provides an installation support point for the top of the isolation tube 2, while the annular structure seals the gap between the top of the isolation tube 2 and the housing 1, preventing external dust and impurities from entering the device and avoiding leakage of internal mist from the top gap. This design achieves a stable installation of the top of the isolation tube 2, improves the structural stability of the top of the device, and provides good sealing and dust prevention, reducing the impact of the external environment on the internal components of the device, extending the service life of the device, and avoiding waste caused by mist leakage.

[0050] In one specific embodiment, an interface tube 36 is connected to the top of the atomizing tube 32; one end of the interface tube 36 extends into the atomizing tube 32 and is press-fitted with the atomizing tube 32, and the other end extends into the mist outlet tube 13, so that the mist outlet tube 13, the interface tube 36 and the atomizing tube 32 are connected in sequence.

[0051] Specifically, the interface tube 36 serves as a transition component connecting the atomizing tube 32 and the mist outlet tube 13. Its interference fit ensures a tight and stable connection with the atomizing tube 32, while its extension into the mist outlet tube 13 enables quick docking, guaranteeing unobstructed mist transmission. This technical advantage solves the connection compatibility problem between the atomizing tube 32 and the mist outlet tube 13. The interface tube 36 allows for smooth connection of atomizing tubes 32 and mist outlet tubes 13 with different diameters, improving the versatility and assembly flexibility of the device structure. Simultaneously, the interference fit ensures a tight seal at the connection point, preventing mist leakage.

[0052] In one specific embodiment, a sealing ring 37 is provided between the interface tube 36 and the mist outlet tube 13 and the isolation tube 2, and the sealing ring 37 is embedded in the outer surface of the interface tube 36.

[0053] Specifically, the sealing ring 37 embedded on the outer surface of the interface tube 36 can fit tightly against the inner surfaces of the mist outlet tube 13 and the isolation tube 2, respectively, filling the gap between the interface tube 36 and the two, forming a double sealing structure. At the same time, the elastic material of the sealing ring 37 has a dual adaptation function: during normal use, the compressive force generated by its elastic deformation can form a radial constraint on the interface tube 36 and the connected atomizing tube 32, helping to stabilize the atomizing core 3 and prevent it from shifting when the mist flows or the device shakes; when the atomizing core 3 is inserted or removed and the interface tube 36 is moved, the elastic sealing ring 37 can convert the rigid friction between the interface tube 36 and the mist outlet tube 13 and the isolation tube 2 into elastic friction, reducing the relative motion resistance through its own deformation, and the embedding method ensures that it will not be lost or shifted during disassembly and assembly, and can continue to play a sealing and adaptation role.

[0054] This design greatly improves the sealing performance of the connection between the interface tube 36 and the mist outlet tube 13 and the isolation tube 2. The double sealing design further reduces the risk of leakage. At the same time, it enables auxiliary positioning and smooth disassembly and assembly of the top of the atomizing core 3. The elastic constraint under normal conditions enhances the stability of the top structure of the device. The low friction characteristics during insertion and removal prevent wear between the interface tube 36 and surrounding components and reduce jamming. The embedded structure of the sealing ring 37 improves its reliability and reduces failures caused by sealing failure or excessive disassembly and assembly resistance, significantly improving the user experience.

[0055] In addition, when the atomizing core 2 is pulled out, the sealing ring 37 will push the liquid between the atomizing tube 32 and the isolation tube 2 to the first liquid inlet 21, so that the liquid flows back to the liquid storage chamber 4 through the first liquid inlet 21, preventing the liquid from flowing out of the mist outlet tube 13, further improving the anti-leakage effect when the atomizing device is replaced, and effectively reducing the waste of liquid.

[0056] In one specific embodiment, a gap fit or transition fit is formed between the atomizing tube 32 and the isolation tube 2.

[0057] Specifically, the clearance fit provides sufficient space for the atomizing tube 32 to slide within the isolation tube 2, reducing frictional resistance and facilitating smooth axial movement of the atomizing core 3. The transition fit, while ensuring a certain degree of sliding, enhances radial positioning accuracy and reduces wobbling. Both fits also avoid jamming problems caused by machining errors. This design significantly improves the ease of assembly and disassembly of the atomizing core 3, reduces operational difficulty, reduces component wear, extends service life, and lowers machining accuracy requirements, thus aiding cost control. Simultaneously, it works synergistically with the sealing ring 34, sealing ring 37, and third flange 121. The sealing ring 34 and sealing ring 37 provide stable elastic sealing at both ends, while the third flange 121 is precisely positioned and fitted in the middle. These two fits provide space for the components to function, avoiding rigid jamming and compensating for positioning and sealing issues through multiple structures, achieving a comprehensive balance between ease of assembly and disassembly, structural stability, and sealing reliability. Preferably, the transition fit ensures that the liquid in the liquid storage chamber 4 enters the atomizing tube 32 only through the first inlet 21 and the second inlet 321, thereby reducing liquid accumulation and residue between the atomizing tube 32 and the isolation tube 2.

[0058] In one specific embodiment, a plurality of first liquid inlets 21 are circumferentially distributed along the circumference of the isolation tube 2, and a plurality of second liquid inlets 321 are circumferentially distributed along the circumference of the atomizing tube 32.

[0059] Specifically, the circumferentially distributed liquid inlets allow liquid to enter the atomizing tube 32 simultaneously from multiple directions, ensuring uniform liquid supply and avoiding insufficient supply caused by blockage of a single inlet. The multiple inlets also improve liquid intake efficiency, meeting the liquid requirements of the heating element 31. The technical effect is to achieve uniform and efficient liquid supply into the atomizing tube 32, improve the stability of the atomization effect, reduce localized overheating caused by uneven liquid supply, and reduce the probability of blockage in the inlet channel, thereby improving the reliability of the device and extending the service life of the heating element 31.

[0060] In one specific embodiment, a liquid storage cotton 38 is provided between the atomizing tube 32 and the heating component 31.

[0061] Specifically, the liquid storage cotton 38 has excellent liquid absorption and retention properties, enabling it to absorb and store the liquid entering the atomizing tube 32, and then slowly and evenly supply it to the heating element 31. This avoids liquid splashing caused by direct impact on the heating element 31. Simultaneously, the liquid storage cotton 38 also acts as a filter, removing minute impurities from the liquid. This design achieves a stable supply of liquid to the heating element 31, effectively preventing choking or uneven atomization caused by liquid splashing, improving the comfort of the atomization experience. The filtering effect of the liquid storage cotton 38 reduces damage to the heating element 31 from impurities, extending its service life. Furthermore, the liquid retention properties of the liquid storage cotton 38 maintain the continuity of atomization operation during brief interruptions in liquid supply.

[0062] Through the above structural design, this utility model allows the atomizing core 3, which includes the first base 33, atomizing tube 32, heating element 31, liquid storage cotton 38, and interface tube 36, to be pulled out of the housing 1 when the atomizing device is inverted. This does not cause liquid to be carried out or leak. During installation, simply align the end of the atomizing core 3 with the interface tube 36 with the bottom of the second base 11 and push the atomizing core 3 into the isolation tube 2 until the first flange 331 abuts against the second base 11. This enables quick assembly and disassembly of the atomizing core 3 while the atomizing device is in the liquid storage state, greatly improving the convenience and safety of assembling and disassembling the atomizing core 3.

[0063] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
