Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic cigarettes, and in particular discloses a lung inhalation bracket structure for electronic cigarettes. Background Art
[0002] E-cigarettes currently on the market operate by heating liquid e-liquid via a heating wire, atomizing it. Users inhale these atomized liquid particles rather than the solid particles produced by traditional tobacco combustion. This shift allows users to avoid inhaling harmful substances such as tar formed during the combustion process, as the content of various components in the e-liquid can be highly precisely controlled.
[0003] The construction of the atomizer core assembly typically involves a threaded connection between the bracket and the main base, with the e-liquid tank fixed to the top of the bracket. However, this connection between the e-liquid tank and the bracket often requires complex sealing processes, which not only increases manufacturing costs but also increases the difficulty of implementation. More importantly, this sealing structure is prone to failure, leading to frequent e-liquid leakage, and urgently needs design and technical improvements. Utility Model Content
[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a lung inhalation bracket structure for an electronic cigarette.
[0005] To achieve the above-mentioned purpose, the utility model provides a lung inhalation bracket structure for an electronic cigarette, including a bracket body, the bracket body is formed with a mounting cavity, and the bracket body is movably mounted on the external atomization core from the mounting cavity; a first connecting part is provided on the top of the bracket body, the first connecting part is connected to the external smoke oil storage box, the bottom of the external smoke oil storage box is cold-welded to the first connecting part, a second connecting part is provided at the bottom of the bracket body, an external thread is provided on the outside of the second connecting part, and the second connecting part is connected to the external base via the external thread.
[0006] The bracket body is designed with a mounting cavity that allows for flexible attachment to the external atomizer core. This design facilitates assembly and disassembly, improving the maintainability and flexibility of the e-cigarette. The first connection is cold-welded to the external liquid reservoir, ensuring a secure and leak-proof connection. The second connection is connected to the external base via external threads. This simple and reliable threaded connection allows for user-friendly replacement or maintenance when the base needs to be opened for part replacement.
[0007] The outer wall of the middle part of the bracket body is convex to form a first circular portion, a second circular portion and a third circular portion. A first mounting groove is formed between the first circular portion and the second circular portion, and a second mounting groove is formed between the second circular portion and the third circular portion. The first mounting groove and the second mounting groove are used to install an external sealing ring.
[0008] The first, second, and third circular portions are protruding from the central outer wall of the bracket body, with a mounting groove formed between them, providing dedicated space for installing the external sealing ring. This design ensures that the sealing ring is securely fixed within the mounting groove, effectively preventing liquid or mist from leaking through the structural gaps of the e-cigarette. It also enhances the structural strength of the bracket body to a certain extent. These circular portions serve as additional support, preventing deformation or damage during use. Because the sealing ring is installed in a dedicated mounting groove, it can be easily removed and replaced with a new one when worn or aged. This design improves the maintainability of the e-cigarette and extends its service life. The presence of two sealing rings provides dual sealing protection, ensuring a more reliable seal within the e-cigarette's internal structure. Even if one sealing ring becomes worn or aged, the other can still function to prevent liquid or mist from leaking.
[0009] The bottom of the bracket body is also equipped with multiple sets of limiting notches. The design of the limiting notches can increase the contact area and friction between the bracket body and the external base or related components, thereby enhancing the stability of the overall structure of the e-cigarette. This helps prevent the e-cigarette from falling off or loosening due to accidental collisions or vibrations during use.
[0010] Two sets of curved seats are located on the top of the first connecting portion. These seats are equipped with air drainage holes, and a gap is formed between the two sets of curved seats to drain the e-liquid. The design of the air drainage holes allows external air to enter the e-cigarette more smoothly, mixing thoroughly with the atomized e-liquid vapor, forming a more flavorful vapor. The curved seats enhance structural stability, helping to improve the durability of the e-cigarette and reduce damage caused by long-term use or improper operation.
[0011] The interior of the second connecting part is provided with an assembly chamber that passes through from top to bottom. The upper part of the assembly chamber is narrowed to form a heating element opening, and a ring-shaped abutting surface is formed between the heating element opening and the assembly chamber. The ring-shaped abutting surface provides a stable support point for the heating element. When the heating element passes through the heating element opening and is placed in the assembly chamber, the abutting surface can ensure that the heating element maintains the correct position and posture, preventing it from shifting or loosening during use. The designed heating element opening and assembly chamber make it easier for users to remove and replace damaged heating elements. This design simplifies the maintenance process of the electronic cigarette and reduces maintenance costs.
[0012] The top surface is coated with silicone to improve the assembly seal. It contacts the external heating wire installed in the mounting cavity. As a high-performance sealing material, silicone possesses excellent elasticity and corrosion resistance. When applied to the top surface, it effectively fills the tiny gap between the top surface and the external heating wire, significantly improving the assembly seal. The top surface is specifically designed to tightly contact and support the external heating wire. This design ensures that the heating wire maintains its correct position and posture within the mounting cavity, preventing it from shifting or loosening during operation.
[0013] The curved seat and the first connecting portion are integrally molded. This one-piece design helps reduce deformation caused by long-term use or external forces. The tight connection between the various parts allows the e-cigarette to better withstand various stresses and pressures. This one-piece design reduces airflow resistance, enabling more efficient vapor production. Compared to traditional split-piece designs, this one-piece design reduces assembly errors. The tight connection between the various parts makes it easier to achieve the expected performance requirements during the manufacturing process.
[0014] The thickness of the arc seat is 0.5-1mm. The arc seat is usually covered with an outer cover, and the arc seat is usually made of lightweight but strong materials, such as aluminum alloy, stainless steel or special plastics. These materials can reduce the overall weight of the product while maintaining sufficient strength. Although the thickness of the arc seat is relatively thin (0.5-1mm), it can still ensure sufficient strength and durability through reasonable material selection and structural design. This design not only meets the functional requirements of the product, but also reduces manufacturing costs. By optimizing the structure and thickness of the arc seat, the atomization effect of the electronic cigarette can be further improved. The thinner arc seat can transfer heat more quickly, thereby accelerating the atomization process of the smoke oil. The thinner arc seat design can reduce the consumption of raw materials, thereby reducing manufacturing costs. This is especially important for large-scale production, which helps companies reduce production costs while maintaining product quality.
[0015] The spacing between the first and second annular portions is the same as the spacing between the second and third annular portions. This uniform spacing simplifies the manufacturing process and reduces the number of mold changes and adjustments. This helps reduce manufacturing costs and improve production efficiency. The uniform spacing design (i.e., the spacing between the first and second annular portions is the same as the spacing between the second and third annular portions) ensures uniform distribution and compression of the sealing ring within the mounting groove. This helps improve the sealing effect of the sealing ring and prevent leakage of smoke oil, mist, or other liquids.
[0016] The air drainage holes are annular. This design more effectively guides air flow and reduces airflow resistance. This allows air to flow more smoothly through the device, improving circulation efficiency. The diameter of the annular air drainage holes can be 5-10mm. This range generally provides sufficient area for smooth air flow while preventing excessive airflow from causing turbulence.
[0017] The inner wall of the bracket body is coated with a protective layer to reduce the adhesion of oil smoke. This protective layer is a zinc coating. The zinc coating has excellent anti-adhesion properties and can effectively reduce the adhesion of oil smoke to the inner wall of the bracket body. This helps keep the interior of the e-cigarette clean and reduces the performance degradation and taste degradation caused by oil smoke accumulation. Due to the reduced oil smoke adhesion, the atomization process of the e-cigarette is purer and has a better taste. The use of the zinc coating helps to preserve the original flavor of the atomizer and enhance the user experience.
[0018] The beneficial effects of the present invention are as follows: the structure of the lung inhalation bracket for electronic cigarettes is cleverly designed, and convenient assembly and disassembly are achieved through flexible installation cavities. Cold welding and external threaded connections ensure a stable seal. The middle circular ring forms an installation groove for installing a sealing ring to prevent leakage. The arc-shaped seat is provided with air drainage holes to optimize the taste of the smoke. At the same time, the assembly chamber and the top surface firmly support the heating element. The overall design improves maintainability, sealing, and structural stability, simplifies the maintenance process, and reduces manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.
[0024] See also Figures 1 to 2As shown, the present invention provides a lung inhalation support structure for an electronic cigarette. It comprises a support body 1, which is formed with a mounting cavity and movably sleeved onto an external atomizer core from the mounting cavity. A first connecting portion 2 is provided at the top of the support body 1, which is connected to an external oil storage tank. The bottom of the external oil storage tank is cold-welded to the first connecting portion 2. A second connecting portion 3 is provided at the bottom of the support body 1, which is externally threaded 4 and connected to the external base via the external thread 4.
[0025] The bracket body 1 is designed with a mounting cavity that allows for flexible attachment to the external atomizer core. This design facilitates assembly and disassembly, improving the maintainability and flexibility of the e-cigarette. The first connecting portion 2 is cold-welded to the external liquid storage tank, ensuring a secure and leak-proof connection and preventing liquid leakage. The second connecting portion 3 is connected to the external base via external threads 4. This threaded connection is simple and reliable, making it easy for users to replace or perform maintenance on the base when opening it for component replacement.
[0026] The outer wall of the middle part of the bracket body 1 is convexly formed to form a first circular portion 5, a second circular portion 6 and a third circular portion 7. A first mounting groove 8 is formed between the first circular portion 5 and the second circular portion 6, and a second mounting groove 9 is formed between the second circular portion 6 and the third circular portion 7. The first mounting groove 8 and the second mounting groove 9 are used to install an external sealing ring.
[0027] The first, second, and third circular portions 5, 6, and 7 are protruded from the central outer wall of the holder body 1, with a mounting groove formed between them, providing dedicated space for installing the external sealing ring. This design ensures that the sealing ring is securely fixed within the mounting groove, effectively preventing leakage of liquid or mist from the electronic cigarette's structural gaps. It also enhances the structural strength of the holder body 1 to a certain extent. These circular portions serve as additional support, preventing deformation or damage during use. Because the sealing ring is mounted in a dedicated mounting groove, it can be easily removed and replaced with a new one if it becomes worn or aged. This design improves the maintainability of the electronic cigarette and extends its service life. The presence of two sealing rings provides dual sealing protection, ensuring a more reliable seal within the electronic cigarette's internal structure. Even if one sealing ring becomes worn or aged, the other can still function to prevent leakage of liquid or mist.
[0028] The bottom of the bracket body 1 is also provided with multiple sets of retaining notches 11. The design of retaining notches 11 increases the contact area and friction between the bracket body 1 and the external base or related components, thereby enhancing the stability of the overall structure of the electronic cigarette. This helps prevent the electronic cigarette from falling off or loosening due to accidental collisions or vibrations during use.
[0029] Two sets of curved seats 12 are located at the top of the first connecting portion 2. These seats are equipped with air drainage holes 13, and a gap 14 is formed between the two sets of curved seats 12 to facilitate the drainage of tobacco liquid. The design of the air drainage holes 13 allows external air to enter the e-cigarette more smoothly, mixing thoroughly with the atomized tobacco liquid vapor to form a more flavorful vapor. The curved seats 12 enhance structural stability, helping to improve the durability of the e-cigarette and reduce damage caused by long-term use or improper operation.
[0030] The interior of the second connecting portion 3 is provided with an assembly chamber that passes through from top to bottom. The upper part of the assembly chamber is narrowed to form a heating element opening, and a ring-shaped abutting surface is formed between the heating element opening and the assembly chamber. The ring-shaped abutting surface provides a stable support point for the heating element. When the heating element passes through the heating element opening and is placed in the assembly chamber, the abutting surface can ensure that the heating element maintains the correct position and posture, preventing it from shifting or loosening during use. The designed heating element opening and assembly chamber make it easier for users to remove and replace damaged heating elements. This design simplifies the maintenance process of the electronic cigarette and reduces maintenance costs.
[0031] The top surface 15 is affixed with silicone for improving the sealing of the assembly. The top surface 15 is used to contact the external heating wire installed in the installation cavity. As a high-performance sealing material, silicone has excellent elasticity and corrosion resistance. When it is affixed to the top surface 15, it can effectively fill the tiny gap between the top surface 15 and the external heating wire, thereby greatly improving the sealing of the assembly. The top surface 15 is specially designed to tightly contact and support the external heating wire. This design ensures that the heating wire maintains the correct position and posture in the installation cavity, preventing it from shifting or loosening during operation.
[0032] The curved seat 12 is integrally formed with the first connecting portion 2. This one-piece design helps reduce deformation caused by long-term use or external forces. The tight connection between the various parts enables the electronic cigarette to better withstand various stresses and pressures. The one-piece design reduces airflow resistance, allowing the electronic cigarette to produce vapor more efficiently. Compared with traditional split-piece designs, the one-piece design reduces errors during assembly. The tight connection between the various parts makes it easier for the electronic cigarette to achieve the expected performance requirements during the manufacturing process.
[0033] The thickness of the arc seat 12 is 0.5-1mm. The arc seat 12 is usually covered with an outer cover, and the arc seat 12 is usually made of lightweight but strong materials, such as aluminum alloy, stainless steel or special plastics. These materials can reduce the overall weight of the product while maintaining sufficient strength. Although the thickness of the arc seat 12 is relatively thin (0.5-1mm), it can still ensure sufficient strength and durability through reasonable material selection and structural design. This design not only meets the functional requirements of the product, but also reduces manufacturing costs. By optimizing the structure and thickness of the arc seat 12, the atomization effect of the electronic cigarette can be further improved. The thinner arc seat 12 can transfer heat more quickly, thereby accelerating the atomization process of the smoke oil. The thinner arc seat 12 design can reduce the consumption of raw materials, thereby reducing manufacturing costs. This is especially important for large-scale production, which helps companies reduce production costs while maintaining product quality.
[0034] The spacing between the first annular portion 5 and the second annular portion 6 is the same as the spacing between the second annular portion 6 and the third annular portion 7. The same spacing design can simplify the manufacturing process and reduce the number of mold changes and commissioning. This helps reduce manufacturing costs and improve production efficiency. The same spacing design (i.e., the spacing between the first annular portion 5 and the second annular portion 6 is the same as the spacing between the second annular portion 6 and the third annular portion 7) ensures uniform distribution and compression of the sealing ring within the mounting groove. This helps improve the sealing effect of the sealing ring and prevent leakage of smoke oil, mist, or other liquids.
[0035] The air drainage holes 13 are annular. This design more effectively guides air flow and reduces airflow resistance. This allows air to flow more smoothly through the device, thereby improving circulation efficiency. The diameter of the annular air drainage holes 13 can be 5-10 mm. This range generally provides sufficient area for smooth air flow while preventing excessive airflow from causing airflow turbulence.
[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
