Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette atomizing tube technology, and in particular to a fixing structure for an atomizing tube and a base. Background Technology

[0002] As the core functional component of e-cigarette products, the performance and reliability of the atomizer directly determine the user experience and product lifespan. The secure connection between the atomizing tube and the liquid reservoir (usually including the reservoir chamber and bottom connection structure) is a crucial aspect of atomizer design. This connection structure must simultaneously meet the following core requirements: a firm and reliable connection, excellent sealing performance to prevent e-liquid leakage, and effective resistance to high-frequency vibrations caused by hand handling, shaking, or drops during use to prevent loosening.

[0003] The common methods for fixing atomizing tubes and bases on the market currently include the following:

[0004] Simple threaded connection: The bottom of the atomizing tube or its extension is directly screwed onto the base or the top of the reservoir. This method is simple in structure and easy to manufacture.

[0005] Silicone O-ring clamping: Based on the threaded connection, a silicone O-ring or other sealing element is added between the contact surfaces, and the seal is achieved by clamping the silicone O-ring.

[0006] The following implementation defects exist: Insufficient sealing performance: Relying solely on the precise fit of the threads themselves is insufficient to provide a long-term reliable liquid seal, especially when temperature changes cause slight thermal expansion and contraction of the material, or when there are tolerances in the thread machining, which easily leads to leakage risks. Long-term use of the sealing ring will cause wear or material aging, affecting its elasticity and sealing life. Therefore, a fixing structure for the atomizing tube and base is proposed to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0008] Therefore, one objective of this utility model is to propose a fixing structure for the atomizing tube and the base, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0009] To achieve the above objectives, one embodiment of the present invention provides an atomizing tube and base fixing structure, including a base, a main cylinder, and an upper sleeve, wherein the main cylinder is fixedly connected to the top of the base, and the main cylinder is used to hold liquid.

[0010] The top of the main cylinder is fixedly connected to an upper sleeve;

[0011] An atomizing tube is fixedly connected to the top of the main tube, and a connector is fixedly connected to the bottom of the atomizing tube. Several outer rings are fixedly connected to the outer surface of the connector, with the edges of the outer rings facing downwards.

[0012] A top ring is fixedly connected to the top opening of the main cylinder, and the edge of the outer ring abuts against the inner side of the top ring.

[0013] A secondary connector is fixedly connected to the outer surface of the middle section of the atomizing tube. A bridge is fixedly connected to both sides of the secondary connector. A tightening head is fixedly connected to the bottom end of the bridge. The tightening head is stepped from the inside to the outside and is threaded into the inside of the upper sleeve.

[0014] A fastening ring is inserted into the gap between the upper part of the tightening head and the upper sleeve, and an atomizing plate that can enter the main cylinder is fixedly connected inside the atomizing tube.

[0015] Preferably, in any of the above solutions, the base is heat-fused to the main cylinder, and the upper sleeve is an internally threaded cylinder.

[0016] The above technical solution refers to the fixing structure between the electronic cigarette atomizing tube and the base and main tube.

[0017] The thinner atomizing tube is externally connected to a secondary connector, which serves as a bridge and tightening head. The tightening head is specially designed with a stepped shape. After it is fully threaded into the upper sleeve, a fastening ring is inserted into the gap. The fastening ring has high surface friction, ensuring a firm connection between the atomizing tube and the main tube. At the same time, the bottom connector of the atomizing tube, in conjunction with the outer ring, is inserted into the top ring above the main tube. The outer ring has a multi-layered, downward-facing edge structure. When the outer ring is fully inserted, the elastic outer ring is tightly clamped inside the top ring, providing good sealing performance. This achieves a firm connection and good sealing between the atomizing tube and the base, effectively preventing leakage.

[0018] Preferably, in any of the above embodiments, the top end of the atomizing tube is fixedly connected to an outlet, and the connector and the outer ring are inserted into the top ring of the main tube.

[0019] The above technical solution employs the following structural composition: The main frame consists of a base, a main cylinder, and an upper sleeve, forming a hierarchical assembly system. The main cylinder (a cylindrical liquid storage container) is fixed to the top of the base via a hot-melt process, and an upper sleeve with an internal thread structure is welded to the top of the main cylinder. The atomizing tube, as the core component, runs through the middle of the structure, with a connector with an outer ring extending from its bottom. The outer ring is made of silicone material in 3-5 stepped rings, with the edges of the rings sloping downwards, causing radial compression deformation when inserted into the top ring at the top of the main cylinder. The reinforcement system includes a rigid support frame composed of a secondary connector, bridges, and stepped tightening heads. The secondary connector is bonded to the middle section of the atomizing tube with epoxy resin, extending to both sides to connect to the tightening heads; all three are integrally injection molded using POM engineering plastic. The sealing assembly includes the inner sealing surface of the top ring and a fastening ring. The fastening ring is a 1.2mm diameter nitrile rubber ring, fitted into the gap between the tightening head and the upper sleeve.

[0020] Preferably, in any of the above solutions, the outer ring is bonded to the connector, and the outer ring is made of silicone.

[0021] The core design of this device is the bottom sealing structure: when the connector of the atomizing tube is inserted into the top ring of the main cylinder, the outer silicone ring is squeezed by the inner wall of the top ring, resulting in a deformation of 0.3-0.5mm, forming a multi-level elastic sealing layer.

[0022] Threaded locking structure: The stepped tightening head engages firmly with the internal thread of the upper sleeve. Tightening generates significant axial pressure, which, combined with the supporting structure of the bridging mechanism, disperses stress.

[0023] Anti-loosening design: The fastening ring generates a certain amount of compression after the thread is fully screwed in, and the friction coefficient of the rubber material of 0.6 can effectively suppress the thread rollback caused by vibration.

[0024] The core advantages of this device are: Dual fixing mechanism: The bottom elastic sealing structure and the top threaded locking form a two-way fixing, increasing the tensile strength to many times that of traditional structures. Dynamic sealing compensation: The elastic deformation of the outer ring can compensate for 0.1mm assembly errors, maintaining stable contact pressure under temperature changes. Anti-loosening guarantee: The friction damping effect of the fastening ring improves the stability of the threaded connection by 40%, making it particularly suitable for the high-frequency vibration environment of electronic cigarettes.

[0025] This structure achieves highly reliable fixation of the core components of the electronic cigarette atomizer through the mechanically optimized layout of the atomizing tube, sub-connector, bridge, and tightening head, combined with a composite sealing scheme of the outer ring and fastening ring. This greatly reduces the leakage rate and extends the service life.

[0026] Preferably, in any of the above solutions, the secondary connector is bonded to the atomizing tube, and the secondary connector, bridge, and tightening head are made of a single piece of plastic.

[0027] Preferably, the fastening ring has a circular cross-sectional shape and is made of rubber.

[0028] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0029] The atomizer tube and base fixing structure employs a dual fixing mechanism: a bottom elastic sealing structure and a top threaded locking form a two-way fixation, increasing tensile strength many times over compared to traditional structures. This fixing structure achieves dynamic sealing compensation: the elastic deformation of the outer ring can compensate for assembly errors of 0.1mm, maintaining stable contact pressure despite temperature changes. Anti-loosening guarantee: the frictional damping effect of the fastening ring improves the stability of the threaded connection by 40%, making it particularly suitable for the high-frequency vibration environment of e-cigarettes.

[0030] This structure achieves highly reliable fixation of the core components of the electronic cigarette atomizer through the mechanically optimized layout of the atomizing tube, sub-connector, bridge, and tightening head, combined with a composite sealing scheme of the outer ring and fastening ring. This greatly reduces the leakage rate and extends the service life.

[0040] like Figure 1-4 As shown, the atomizing tube and base fixing structure includes a base 1, a main cylinder 2, and an upper sleeve 3. The main cylinder 2 is fixedly connected to the top of the base 1 and is used to hold liquid.

[0041] The top of the main tube 2 is fixedly connected to the upper sleeve 3;

[0042] Atomizing tube 4 is fixedly connected to the top of the main tube 2, and a connector 5 is fixedly connected to the bottom of the atomizing tube 4. Several outer rings 6 are fixedly connected to the outer surface of the connector 5, with the edges of the outer rings 6 facing downwards.

[0043] The top opening of the main tube 2 is fixedly connected to the top ring 7, and the edge of the outer ring 6 abuts against the inner side of the top ring 7;

[0044] A secondary connector 8 is fixedly connected to the outer surface of the middle section of the atomizing tube 4. A bridge 9 is fixedly connected to both sides of the secondary connector 8. A tightening head 10 is fixedly connected to the bottom end of the bridge 9. The tightening head 10 is stepped from the inside to the outside and is threaded into the inside of the upper sleeve 3.

[0045] A fastening ring 11 is inserted into the gap between the upper part of the tightening head 10 and the upper sleeve 3. An atomizing plate that can enter the interior of the main tube 2 is fixedly connected inside the atomizing tube 4.

[0046] Example 1: The base 1 and the main cylinder 2 are heat-fused together, and the upper sleeve 3 is an internally threaded cylinder. An outlet is fixedly connected to the top of the atomizing tube 4, and the connector 5 and outer ring 6 are inserted into the top ring 7 of the main cylinder 2. The outer ring 6 is bonded to the connector 5, and the outer ring 6 is made of silicone. The auxiliary connector 8 is bonded to the atomizing tube 4, and the auxiliary connector 8, bridge 9, and fastening head 10 are made of a single piece of plastic. The fastening ring 11 has a circular cross-sectional shape and is made of rubber.

[0047] Example 2: This fixing structure refers to the fixing structure of the electronic cigarette atomizing tube 4 with the base 1 and the main tube 2. A secondary connector 8 is externally connected to the thinner atomizing tube 4, which connects to the bridge 9 and the tightening head 10. The tightening head 10 has a special design; it is stepped and threaded to the upper sleeve 3. After it is fully threaded, a fastening ring 11 is inserted into the gap. The fastening ring 11 has high surface friction, ensuring a firm connection between the atomizing tube 4 and the main tube 2. Simultaneously, the bottom connector 5 of the atomizing tube 4, in conjunction with the outer ring 6, is inserted into the top ring 7 above the main tube 2. The outer ring 6 has a multi-layered, downward-facing edge structure. When the outer ring 6 is fully inserted, its elasticity ensures a tight seal inside the top ring 7, achieving a firm and well-sealed connection between the atomizing tube 4 and the base 1, effectively preventing leakage. Device structure composition: The main frame consists of a base 1, main tube 2, and upper sleeve 3 forming a hierarchical assembly system. The main cylinder 2 (a cylindrical liquid storage container) is fixed to the top of the base 1 using a hot-melt process. An upper sleeve 3 with an internal thread structure is welded to the top of the main cylinder 2. The atomizing tube 4, as the core component, runs through the middle of the structure, with a connector 5 extending from its bottom, featuring an outer ring 6. The outer ring 6 is made of silicone and consists of 3-5 layers of stepped rings with downward-sloping edges, causing radial compression deformation when inserted into the top ring 7 at the top of the main cylinder 2. The reinforcement system comprises a rigid support frame consisting of a secondary connector 8, bridges 9, and stepped tightening heads 10. The secondary connector 8 is bonded to the middle section of the atomizing tube 4 with epoxy resin, extending to both sides of the bridges 9 to connect to the tightening heads 10. All three components are integrally injection molded from POM engineering plastic. The sealing assembly includes the inner sealing surface of the top ring 7 and a fastening ring 11. The fastening ring 11 is a 1.2mm diameter nitrile rubber ring, fitted into the gap between the tightening head 10 and the upper sleeve 3.

[0048] Example 3: Core design of this device: Bottom sealing structure: When the connector 5 of the atomizing tube 4 is inserted into the top ring 7 of the main tube 2, the silicone outer ring 6 is squeezed by the inner wall of the top ring 7, resulting in a deformation of 0.3-0.5mm, forming a multi-level elastic sealing layer.

[0049] Threaded locking structure: The stepped tightening head 10 engages firmly with the internal thread of the upper sleeve 3. When tightened, it generates a high axial pressure, which, together with the support structure of the bridge 9, disperses the stress.

[0050] Anti-loosening design: After the thread is fully screwed in, the fastening ring 11 generates a certain amount of compression, and the friction coefficient of the rubber material of 0.6 can effectively suppress the thread retraction caused by vibration.

[0051] The working principle of this utility model is as follows:

[0052] Sealing connection: When the connector 5 at the bottom of the atomizing tube 4 is inserted into the top ring 7 at the top of the main tube 2, the outer ring 6 made of silicone material is radially compressed by the inner wall of the top ring 7. The outer ring 6 adopts a 3-5 layer stepped ring design, with the edge of each layer sloping downwards. During the insertion process, it deforms step by step, generating an elastic compression of 0.3-0.5mm, forming a multi-layer annular sealing surface.

[0053] Dynamic compensation: When the ambient temperature changes or the liquid pressure fluctuates, the elastic deformation of the silicone outer ring 6 can adaptively adjust the contact pressure, compensate for the 0.1mm assembly tolerance, ensure that the sealing surface is always tightly fitted, and prevent liquid from leaking from the joint between the main cylinder 2 and the atomizing tube 4.

[0054] Thread engagement: The stepped tightening head 10 engages with the internal thread of the upper sleeve 3. When tightened, the stepped structure of the tightening head 10 gradually embeds into the thread groove, generating axial pressure. This pressure is transmitted to the auxiliary connector 8 through the bridge 9, and finally dispersed to the middle section of the atomizing tube 4, avoiding cracking of the plastic parts caused by local stress concentration.

[0055] Rigid support: The auxiliary connector 8, the bridge 9 and the tightening head 10 are integrally injection molded from POM engineering plastic to form a triangular rigid support frame, which converts the axial tensile force generated by the threaded locking into a uniform clamping force on the atomizing tube 4, and increases the tensile strength to 2.5 times that of the traditional snap-fit ​​structure.

[0056] Friction damping: After the thread is fully screwed in, the nitrile rubber fastening ring 11 is compressed in the gap between the fastening head 10 and the upper sleeve 3. Its surface friction coefficient reaches 0.6, which generates a continuous damping effect, suppressing the thread backing caused by the high-frequency vibration (20-200Hz) of the electronic cigarette, and improving the connection stability by 40%.

[0057] Stepped limit: The stepped design of the tightening head 10 forms a mechanical limit with the inner wall of the upper sleeve 3 when the thread is screwed to the bottom, further preventing loosening.

[0058] Liquid conduction: The e-liquid in the main tube 2 enters the bottom of the atomizing tube 4 through the gap between the top ring 7 and the outer ring 6, and is transported to the atomizing plate position through the guide groove of the connector 5.

[0059] Atomization operation: After being powered on, the atomizing plate atomizes the liquid, and the atomized gas is sprayed out through the outlet at the top of the atomizing tube 4. At this time, the sealing structure of the outer ring 6 can withstand an atomization pressure of 0.05-0.1MPa, preventing liquid backflow.

[0060] Compared with the prior art, the present invention has the following advantages:

[0061] The atomizer tube and base fixing structure employs a dual fixing mechanism: a bottom elastic sealing structure and a top threaded locking form a two-way fixation, increasing tensile strength to several times that of traditional structures. This fixing structure achieves dynamic sealing compensation: the elastic deformation of the outer ring 6 can compensate for 0.1mm assembly errors, maintaining stable contact pressure under temperature changes. Anti-loosening guarantee: the friction damping effect of the fastening ring 11 improves the stability of the threaded connection by 40%, making it particularly suitable for the high-frequency vibration environment of e-cigarettes.

[0062] This structure achieves highly reliable fixation of the core components of the electronic cigarette atomizer through the mechanically optimized layout of the atomizing tube 4, the auxiliary connector 8, the bridge 9, and the tightening head 10, combined with the composite sealing scheme of the outer ring 6 and the fastening ring 11. This greatly reduces the leakage rate and extends the service life.
