Description

Technical Field

[0001] This utility model relates to the field of ignition device technology, and in particular to a lighter with a protective structure. Background Technology

[0002] A windproof lighter is a lighter manufactured using Bernoulli's principle, and its flame differs from that of a regular lighter. Windproof lighters can ignite even in harsh environments such as strong winds. Utilizing Bernoulli's principle, windproof lighters use a higher velocity to expel gas, creating lower pressure at appropriate points in the airflow channel to draw in more air, which mixes thoroughly with the lighter's fuel gas, resulting in a vigorous reaction and combustion. The high temperature of the flame causes the gas to expand further, increasing pressure and propelling the flame out at a higher velocity. Therefore, it is not easily extinguished. If the flame does go out, the high-temperature metal mesh will instantly reignite it.

[0003] Currently, windproof lighters on the market usually have a cover hinged to the side of the outer shell corresponding to the ignition tower. When the lighter is not in use, the cover is closed, covering the ignition tower. When the lighter needs to be used for ignition, the cover is manually opened for ignition. After ignition, the cover is closed again to cover the ignition tower. This not only prevents users from being burned, but also prevents impurities from falling into the ignition tower and clogging the gas passage or nozzle, which could lead to unstable flame, failure to ignite, or incomplete combustion.

[0004] However, during daily use, users often forget to close the lid, and users or others may accidentally touch the ignition peg and get burned. In addition, if the lid is not closed for a long time, the chance of impurities adhering to the ignition peg will also increase. Therefore, it is necessary to improve the existing lighters to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a lighter with a protective structure. This invention prevents users from accidentally touching the ignition pagoda and burning their skin by setting a structure that can automatically close the top cover. It also effectively prevents impurities from adhering to the ignition pagoda, and has the advantages of higher safety and better ignition effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lighter with a protective structure, comprising a shell, a gas box and a piezoelectric igniter disposed within the shell, a fixed base disposed at the upper end of the shell, a button movably disposed on the base and linked with the piezoelectric igniter, an ignition bracket disposed on the fixed base, and an ignition tower disposed on the ignition bracket. The gas box is connected to the ignition tower via a gas pipe, and the button activates the piezoelectric igniter to generate an electric arc that ignites the gas ejected from the ignition tower. The lighter also includes a protective structure comprising two protective covers symmetrically disposed on both sides of the ignition bracket to cover the ignition tower, and elastic elements for resetting the two protective covers. The two protective covers are linked to the button via a transmission assembly. When the button activates the piezoelectric igniter, the button, through the transmission assembly, drives the two protective covers to move away from each other, exposing the ignition tower. When the button resets, the elastic elements drive the two protective covers to reset and cover the ignition tower.

[0007] By adopting the above technical solution, when the lighter is ignited by pressing the button, two protective covers open to expose the ignition tower for the user to light. When the button is released, the ignition tower extinguishes, and the two protective covers return to their original position via a reset mechanism, covering the ignition tower and forming a protective structure. The automatic closing mechanism prevents users from accidentally touching the ignition tower and causing burns, while also effectively preventing impurities from adhering to the ignition tower, offering advantages in both safety and ignition performance.

[0008] The present invention is further configured such that the transmission assembly includes a transmission rod, one end of which is connected to a button, and the other end of which is provided with a V-shaped push block. Two protective covers are symmetrically hinged to the ignition bracket, and each of the two protective covers has a follow-up inclined surface on its inner side for cooperating with the V-shaped push block. When the transmission rod drives the V-shaped push block to move downward, the V-shaped push block acts on the follow-up inclined surface of the two protective covers, causing the two protective covers to flip outward and open.

[0009] By adopting the above technical solution, the follow-up inclined surfaces of the two protective covers form a V-shaped groove structure, which cooperates with the V-shaped push block. When the V-shaped push block moves downward, it can easily push open the two protective covers. The two protective covers rotate outward around their respective hinge points to expose the ignition pagoda. The structure is simple and reliable.

[0010] The present invention is further configured such that the inner end of the button is provided with a locking block, the transmission rod is provided with a locking groove, and the locking block and the locking groove are inserted and engaged and locked together by fasteners.

[0011] By adopting the above technical solution, the connection structure between the button and the transmission rod is simple and reliable, and easy to disassemble and assemble.

[0012] The present invention is further configured such that a sliding groove is provided vertically along the upper edge of the fixed middle seat, the button is slidably disposed in the sliding groove along the vertical edge, a through hole with a width smaller than that of the button is provided at the inner end of the sliding groove, and the locking block passes through the through hole and is engaged with the locking groove of the transmission rod.

[0013] By adopting the above technical solution, the button is guided and restricted, enabling it to move stably and accurately along the vertical direction, thus ensuring the reliability of ignition and opening operations.

[0014] The present invention is further provided in that the inner side of the ignition bracket is provided with a guide rib extending vertically, and the V-shaped push block is provided with a guide groove that cooperates with the guide rib.

[0015] By adopting the above technical solution, the transmission rod can be guided so that it can only move vertically, thereby applying the same force to the two protective covers, ensuring that they open or close simultaneously, and improving structural reliability.

[0016] The present invention is further configured to include a swing arm, one end of which is hinged to the upper end of the gas box, the other end of which is engaged with the lower end of the transmission rod, and the middle part of which is engaged with the upper pressing end of the piezoelectric igniter.

[0017] By adopting the above technical solution, the linkage between the button and the piezoelectric igniter can be realized, so that the button can trigger the piezoelectric igniter to generate an electric arc.

[0018] The present invention is further configured such that a first contact shaft is provided at one end of the swing arm near the transmission rod, the outer circular surface of the first contact shaft abuts against the lower end surface of the transmission rod, and a second contact shaft is provided at the bottom middle part of the swing arm, the outer circular surface of the second contact shaft abuts against the upper pressing end of the piezoelectric igniter.

[0019] By adopting the above technical solution, friction is reduced, resulting in smoother operation and less likelihood of jamming.

[0020] The present invention is further configured such that the elastic element includes a V-shaped torsion spring, the ignition bracket is provided with a supporting central shaft, and each of the two protective covers is provided with a follower protrusion. The middle part of the V-shaped torsion spring is sleeved on the supporting central shaft, and the two ends of the V-shaped torsion spring respectively abut against the corresponding follower protrusion, so as to cause the two protective covers to abut tightly.

[0021] By adopting the above technical solution, when the two buttons drive the two protective covers to open via the transmission rod, the V-shaped torsion spring is compressed and stores energy. When the buttons are released, the V-shaped torsion spring releases energy and acts on the follower protrusions on the two protective covers, causing the protective covers to rotate back around the hinge point until the two come into contact, completely covering the ignition tower to form a protective structure. The reset structure is simple and reliable, which is conducive to production and assembly. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: As attached Figures 1-6The lighter shown includes a protective structure, comprising a casing 1, a gas tank 2 and a piezoelectric igniter 3 disposed within the casing 1, a fixed base 4 (composed of a front cover and a rear cover connected by screws) disposed on the upper end of the casing 1, a button 5 movably disposed on the base and linked to the piezoelectric igniter 3, an ignition bracket 6 disposed on the fixed base 4, and an ignition tower 7 disposed on the ignition bracket 6. The gas tank 2 is connected to the ignition tower 7 via a gas pipe, and a gas valve is provided between the two. The button 5 activates the piezoelectric igniter 3 to generate an electric arc. Simultaneously, the button 5 opens the gas valve via a rocker arm, allowing gas from the gas tank 2 to be delivered to the ignition tower 7 via the gas pipe. The electric arc ignites the gas emitted from the ignition tower 7, thus igniting the lighter's base. This structure is a mature technology in the market, so the specific structure will not be described in detail here. The lighter also includes a protective structure, which includes two protective covers 8 symmetrically arranged on both sides of the ignition bracket 6 to cover the ignition tower 7, and elastic elements 9 for resetting the two protective covers 8. The two protective covers 8 are linked to the button 5 through a transmission component 10. The protective covers 8 are hollow and open on the inside, that is, the two protective covers 8 are open on opposite sides. When the button 5 activates the piezoelectric igniter 3, the button 5 drives the two protective covers 8 to move away from each other through the transmission component 10, exposing the ignition tower 7. When the button 5 resets, the elastic elements 9 drive the two protective covers 8 to reset and cover the ignition tower 7. When the button 5 is operated to ignite the lighter, the two protective covers 8 open to expose the ignition tower 7 for the user to use. When the button 5 is released, the ignition tower 7 extinguishes, and the two protective covers 8 reset through the reset element, covering the ignition tower 7, forming a protective structure. Its automatically closing top cover prevents users from accidentally touching the ignition pagoda 7 and burning their skin, while also effectively preventing impurities from adhering to it, resulting in higher safety and better ignition performance. Furthermore, its unique design offers good playability, giving the company a strong competitive edge in the market.

[0031] As attached Figures 1-6As shown, the transmission assembly 10 includes a transmission rod 11. One end of the transmission rod 11 is connected to the button 5, and the other end of the transmission rod 11 is integrally provided with a V-shaped push block 12. Two protective covers 8 are symmetrically hinged to the ignition bracket 6. That is, the ignition bracket 6 is provided with a rotating shaft, and the protective covers 8 are provided with shaft holes. The inner side of each of the two protective covers 8 is provided with a follower inclined surface 13 for cooperating with the V-shaped push block 12. When the two protective covers 8 are in contact, that is, when the protective covers 8 are closed, the two follower inclined surfaces 13 form a V-shaped structure. When the transmission rod 11 drives the V-shaped push block 12 to move downward, the V-shaped push block 12 acts on the follower inclined surfaces 13 of the two protective covers 8, causing the two protective covers 8 to flip outward and open. The follow-up inclined surfaces 13 of the two protective covers 8 form a V-shaped groove structure, which cooperates with the V-shaped push block 12, so that when the V-shaped push block 12 moves downward, it can easily push open the two protective covers 8. The two protective covers 8 rotate outward around their respective hinge points to expose the ignition pagoda 7. The structure is simple and reliable.

[0032] As attached Figure 3 As shown, the inner end of the button 5 is provided with a locking block 14, and the transmission rod 11 is provided with a locking groove 15. The cross-section of the locking groove 15 is approximately the same as that of the locking block 14. The locking block 14 and the locking groove 15 are inserted into each other and locked together by fasteners, which are screws. The connection structure between the button 5 and the transmission rod 11 is simple and reliable, and is very convenient to assemble and disassemble.

[0033] As attached Figure 3 As shown, a vertical groove 16 is formed on the fixed base 4. The button 5 is slidably disposed in the groove 16. A through hole 17 with a width smaller than that of the button 5 is formed at the inner end of the groove 16. The locking block 14 passes through the through hole 17 and engages with the locking groove 15 of the transmission rod 11. The lower side of the transmission rod 11 abuts against the inner side of the outer casing 1 to form a limiting position. This guides and restricts the button 5, enabling it to move stably and accurately along the vertical direction, ensuring the reliability of ignition and cover opening operations.

[0034] As attached Figure 4 and attached Figure 5 As shown, the ignition bracket 6 has a guide rib 18 extending vertically along its inner side, and the V-shaped push block 12 has a guide groove 19 that cooperates with the guide rib 18. This design guides the transmission rod 11 so that it can only move vertically, thereby applying the same force to the two protective covers 8, ensuring that they open or close simultaneously, resulting in better structural reliability.

[0035] As attached Figure 3As shown, the lighter also includes a swing arm 20. One end of the swing arm 20 is hinged to the upper end of the gas tank 2, i.e., a rotating shaft is provided on the swing arm 20, and a shaft hole is provided at the upper end of the gas tank 2 for the rotating shaft to pass through. The other end of the swing arm 20 abuts against the lower end of the transmission rod 11, and the middle part of the swing arm 20 abuts against the upper pressing end of the piezoelectric igniter 3. This design enables the linkage between the button 5 and the piezoelectric igniter 3, so that the button 5 triggers the piezoelectric igniter 3 to generate an electric arc.

[0036] As attached Figure 3 As shown, a first contact shaft 21 is integrally formed at one end of the swing arm 20 near the transmission rod 11. The outer circular surface of the first contact shaft 21 abuts against the lower end surface of the transmission rod 11. A second contact shaft 22 is integrally formed at the bottom middle part of the swing arm 20. The outer circular surface of the second contact shaft 22 abuts against the upper pressing end of the piezoelectric igniter 3. This structure has less friction, making operation smoother and less prone to jamming.

[0037] As attached Figure 6 As shown, the elastic element 9 includes a V-shaped torsion spring 23, the ignition bracket 6 is provided with a supporting central shaft 24, and each of the two protective covers 8 is provided with a follower protrusion 25. The middle part (elastic part) of the V-shaped torsion spring 23 is sleeved on the supporting central shaft 24, and the two ends of the V-shaped torsion spring 23 respectively abut against the corresponding follower protrusion 25, so that the two protective covers 8 are tightly pressed together. When the two buttons 5 drive the two protective covers 8 to open through the transmission rod 11, the V-shaped torsion spring 23 is compressed and stores energy. When the buttons 5 are released, the V-shaped torsion spring 23 releases energy and acts on the follower protrusion 25 on the two protective covers 8, so that the protective covers 8 rotate back to their original position around the hinge point until the two abut against each other, completely covering the ignition tower 7 to form a protective structure. The reset structure is simple and reliable, which is conducive to production and assembly.
