Abstract
Description
Technical Field
[0001] This invention relates to the field of aerogel insulation, specifically to a ring-shaped aerogel insulation structure. Background Technology
[0002] Aerogel, with its excellent properties such as extremely low thermal conductivity and lightweight, has become an ideal heat insulation material in the field of e-cigarettes. Its core function is to block the high temperature generated by the heating component from being transmitted to the outer shell of the e-cigarette, preventing users from getting burned when holding it, while also protecting the stable operation of the electronic components inside the e-cigarette.
[0003] Existing aerogel insulation structures used in e-cigarettes are mostly fixed-size sheet or ring-shaped rigid structures, which have poor adaptability. There are slight batch differences in the inner wall size of e-cigarette rods, and it is difficult for fixed-size insulation structures to fit perfectly with the inner walls of different batches of rods, easily forming gaps. High-temperature gas and heat can be transferred through the gaps, significantly weakening the insulation effect. Moreover, traditional insulation structures only have simple physical contact with the inner wall of the rod, without an active sealing design. The vapor generated by the heating element can easily leak through the gaps, affecting the atomization taste. At the same time, external impurities may also enter the heating area through the gaps, contaminating the components. In terms of installation, in order to ensure a good fit, the dimensional tolerances between the insulation structure and the inner wall of the rod must be strictly controlled, which increases the processing cost. Furthermore, during assembly, dimensional deviations can easily lead to jamming or insecure assembly. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a ring-shaped aerogel insulation structure that can flatten the aerogel insulation layer, allowing it to fit tightly against the inner wall of the electronic cigarette, thus achieving a good sealing and insulation effect, and solving the problems mentioned in the background art. Technical solution
[0005] To achieve the above objectives, the present invention provides the following technical solution: a ring-shaped aerogel thermal insulation structure, comprising a ring-shaped soft aerogel, wherein pressure rings are provided on both the upper and lower sides of the ring-shaped soft aerogel, and mounting plates are provided on both inner walls of the ring-shaped soft aerogel, wherein a connecting mechanism is provided between the mounting plate and the ring-shaped soft aerogel, and the ring-shaped soft aerogel and the mounting plate are connected by the connecting mechanism for limiting the connection, wherein a fixing shell is fixedly provided on the side of the mounting plate away from the ring-shaped soft aerogel, and movable rings are slidably provided on both sides of the interior of the fixing shell, wherein an L-shaped rod is fixedly sleeved in the middle of the movable ring, and the horizontal end of the L-shaped rod is fixedly connected to the corresponding pressure ring, and a limiting mechanism is provided inside the fixing shell to restrict the movement of the L-shaped rod.
[0006] Preferably, the connecting mechanism includes a threaded rod and a T-block. T-grooves are provided on both sides of the upper surface of the annular soft aerogel. The T-block is engaged inside the T-grooves. A threaded hole is provided on the inner wall of one side of the upper end of the T-grooves. The threaded rod is threaded into the inside of the threaded hole. One end of the threaded rod extends to the outside of the threaded hole, and the outer end of the threaded rod abuts against the upper surface of the T-block.
[0007] Preferably, the limiting mechanism includes a stop and a slider. Two grooves are formed on one inner wall of the fixed shell. The slider is slidably disposed inside the groove. The stop is fixedly disposed on the side of the slider near the movable ring. The stop abuts against the side of the movable ring near the corresponding pressure ring. A spring is fixedly disposed on the side of the slider away from the stop. The two ends of the spring are fixedly connected to the corresponding slider and the inner wall of the groove, respectively.
[0008] Preferably, a pull plate is abutting against the side of the fixed shell away from the mounting plate, and a connecting rod is fixedly provided on the side of the slider near the pull plate, with one end of the connecting rod extending to the outside of the groove and fixedly connected to the pull plate.
[0009] Preferably, the mounting plate is arranged in an arc shape on the side near the annular soft aerogel.
[0010] Preferably, the threaded rod has an operating groove at one end near the T-slot.
[0011] Preferably, both the fixed shell and the movable ring have rectangular cross-sections, and the inner wall of the movable ring abuts against the inner wall of the fixed shell.
[0012] Preferably, the compression ring is a rigid aerogel ring.
[0013] Compared with the prior art, the present invention provides a ring-shaped aerogel thermal insulation structure, which has the following beneficial effects: This annular aerogel insulation structure works by passing one pressure ring through the middle of the annular soft aerogel, placing two pressure rings on either side of the aerogel. A T-shaped block is then inserted into a T-groove, and the threaded rod is rotated so that it blocks above the T-shaped block, completing the installation of the fixed shell. Next, the two pressure rings are pressed towards the side closest to the annular soft aerogel, causing the two movable rings to move towards each other, flattening the aerogel. Releasing the pull plate allows the two side blocks to reset under the spring force, blocking the movable rings on the side closest to the corresponding pressure ring. This limits the movement of the pressure rings on both sides, ensuring stable contact between the annular soft aerogel and the inner wall of the electronic cigarette, significantly improving the sealing and insulation effect of the annular soft aerogel.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see Figure 1-5 A ring-shaped aerogel insulation structure includes a ring-shaped soft aerogel 1. Pressure rings 2 are provided on both the upper and lower sides of the ring-shaped soft aerogel 1. Mounting plates 3 are abutted against each other on both inner walls of the ring-shaped soft aerogel 1. A connecting mechanism is provided between the mounting plate 3 and the ring-shaped soft aerogel 1. The ring-shaped soft aerogel 1 and the mounting plate 3 are connected by the connecting mechanism. A fixed shell 4 is fixedly provided on the side of the mounting plate 3 away from the ring-shaped soft aerogel 1. Movable rings 6 are slidably provided on both sides inside the fixed shell 4. An L-shaped rod 5 is fixedly sleeved in the middle of the movable ring 6. The horizontal end of the L-shaped rod 5 is fixedly connected to the corresponding pressure ring 2. A limiting mechanism is provided inside the fixed shell 4 to restrict the movement of the L-shaped rod 5.
[0018] The connecting mechanism includes a threaded rod 12 and a T-block 11. T-slots are provided on both sides of the upper surface of the annular soft aerogel 1. The T-block 11 is snapped into the inside of the T-slot. A threaded hole is provided on the inner wall of the upper end of the T-slot. The threaded rod 12 is threaded into the inside of the threaded hole. One end of the threaded rod 12 extends to the outside of the threaded hole. The outer end of the threaded rod 12 abuts against the upper surface of the T-block 11.
[0019] The limiting mechanism includes a stop block 8 and a slider 7. Two grooves are opened on one side of the inner wall of the fixed shell 4. The slider 7 is slidably disposed inside the groove. The stop block 8 is fixedly disposed on the side of the slider 7 near the movable ring 6. The stop block 8 abuts against the side of the movable ring 6 near the corresponding pressure ring 2. A spring 10 is fixedly disposed on the side of the slider 7 away from the stop block 8. The two ends of the spring 10 are fixedly connected to the corresponding slider 7 and the inner wall of the groove, respectively.
[0020] A pull plate 13 is provided on the side of the fixed shell 4 away from the mounting plate 3. A connecting rod 9 is fixedly provided on the side of the slider 7 near the pull plate 13. One end of the connecting rod 9 extends to the outside of the groove and is fixedly connected to the pull plate 13.
[0021] The mounting plate 3 is arranged in an arc shape on the side near the annular soft aerogel 1.
[0022] An operating groove is provided at one end of the threaded rod 12 near the T-slot.
[0023] Both the fixed shell 4 and the movable ring 6 have rectangular cross-sections, and the inner wall of the movable ring 6 abuts against the inner wall of the fixed shell 4.
[0024] The compression ring 2 is a rigid aerogel ring.
[0025] In summary, this annular aerogel insulation structure, during use, first places the device on the outside of the electronic cigarette's heating element. Pulling the pull plate 13 causes the slider 7 to compress the spring 10 via the connecting rod 9, disengaging the stop block 8 from the movable ring 6. Then, pressing the upper and lower pressure rings 2 in opposite directions causes the movable ring 6 to slide within the fixed shell 4 via the L-shaped rod 5, compressing the annular soft aerogel 1 radially until the outer side of the annular soft aerogel 1 is tightly against the inner wall of the electronic cigarette. Releasing the pull plate 13 causes the spring 10 to reset, pushing the slider 7 to engage the stop block 8 against the movable ring 6, limiting and fixing the position of the pressure ring 2, maintaining a stable fit between the annular soft aerogel 1 and the inner wall of the electronic cigarette, achieving a sealed and heat-insulating effect. The arc-shaped structure of the mounting plate 3 adapts to the inner wall of the annular soft aerogel 1, and the connection mechanism formed by the T-shaped block 11 and the threaded rod 12 ensures a stable connection between the mounting plate 3 and the annular soft aerogel 1, preventing displacement during use.
