Detailed Implementation

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of this utility model, not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0023] A lighter typically consists of a lighter cover and a lighter body, which are connected by a hinge to achieve the opening and closing function. A traditional lighter case includes two parts: an upper cover and a lower cover. When in use, the upper cover covers the lighter cover, while the lower cover covers the lighter body, providing protection for the lighter.

[0024] However, because the lighter casing needs to be opened and closed frequently, this part is prone to wear and tear, and may even crack. Frequent movement causes the casing material to age, thus shortening the overall lifespan of the casing.

[0025] Therefore, this utility model proposes a lighter casing, referring to... Figures 1-2 It includes an upper housing 100, a lower housing 200, a first metal frame 300 and a second metal frame 400. The upper housing 100 is provided with a first receiving groove for inserting a lighter cover; the lower housing 200 is provided with a second receiving groove for inserting a lighter body. The first metal frame 300 is fixedly connected to the bottom of the upper housing 100 and the second metal frame 400 is fixedly connected to the top of the lower housing 200.

[0026] The first receiving groove of the upper housing 100 accommodates and fixes the lighter's cap, protecting the cap and assisting in positioning. The second receiving groove of the lower housing 200 accommodates the lighter body, ensuring its stable placement within the housing and providing protection. The first metal frame 300 and the second metal frame 400 protect the opening and closing action, preventing excessive stress on the edges. By setting the first metal frame 300 and the second metal frame 400 at the contact edges of the lighter housing's opening and closing points, wear at the opening and closing points is reduced, extending the lifespan of the lighter housing and better protecting the lighter. The presence of the metal frames also enhances the aesthetics and texture of the lighter housing to some extent, increasing the product's competitiveness.

[0027] During assembly, the lighter's cap is inserted into the first receiving groove of the upper housing 100 to secure it and protect it. Then, the lighter body is inserted into the second receiving groove of the lower housing 200, ensuring it is stably placed within the second receiving groove and preventing it from easily shaking inside the housing, thus providing effective protection for the lighter body. When the lighter is needed, the lighter housing is held, and the upper housing 100 and lower housing 200 are separated and joined together through a conventional opening and closing action, such as flipping the cap. At this time, the first metal frame 300 and the second metal frame 400 interact at the contact edges of the opening and closing. This avoids excessive stress on the edges due to the opening and closing action, such as preventing cracking or deformation of the edges due to frequent opening and closing. On the other hand, it reduces direct friction at the opening and closing points, reducing wear and tear, allowing the entire lighter housing to withstand more opening and closing operations while maintaining good condition.

[0028] The lighter's hinge and casing may interfere with each other, affecting the smoothness of the lighter's opening and closing. Therefore, in one embodiment, the first metal frame 300 has a first clearance opening 310, and the second metal frame 400 has a second clearance opening 410. The first clearance opening 310 and the second clearance opening 410 are arranged opposite to each other; the first clearance opening 310 and the second clearance opening 410 form a clearance space for the lighter's hinge to pass through. By opening a first clearance opening 310 in the first metal frame 300 and a second clearance opening 410 in the second metal frame 400, and setting them opposite each other to form a clearance space to accommodate the lighter's pivot, the pivot can rotate freely in the clearance space when the lighter is opened and closed inside the casing. This avoids friction, collision, and other obstructions between the pivot and the casing, greatly improving the smoothness of the opening and closing action and reducing the damage to the casing caused by additional stress due to interference. Especially in the case of frequent opening and closing, it can effectively reduce the probability of wear and deformation of the first metal frame 300 and the second metal frame 400 and other related parts.

[0029] To ensure sufficient strength, the outer shell may use thicker materials or a relatively complex overall structure, leading to material waste, increased costs, and a rather monotonous overall appearance. Therefore, in one embodiment, the upper shell 100 includes a first shell 110, a second shell 120, and a first metal support rib 130. A first cavity is formed between the first shell 110 and the second shell 120. The first metal support rib 130 is disposed within the first cavity and is fixedly connected to the first shell 110. The first metal support rib 130 extends to the outer surface of the second shell 120, and the second shell 120 is fixedly connected to the first metal support rib 130. The outer surface of the first metal support rib 130 is flush with the outer surface of the second shell 120. When the casing is subjected to external force, the first metal support rib 130 effectively disperses stress and enhances the deformation resistance of the upper casing 100. By using the first metal support rib 130 to provide support, the material thickness of the first casing 110 and the second casing 120 can be appropriately reduced, thereby saving materials and reducing production costs. In terms of appearance, the first metal support rib 130 becomes a unique decorative element, breaking the monotony of the traditional casing appearance, adding a unique shape and line beauty to the lighter casing, improving the overall aesthetics of the product, and meeting consumers' demand for personalized and beautiful products.

[0030] Specifically, the first metal support rib 130 is glued and fixed to the first housing 110 and the second housing 120.

[0031] In everyday use scenarios such as opening and closing the casing and being subjected to external impacts, components are prone to loosening and displacement. Therefore, in one embodiment, both ends of the first metal support rib 130 are fixedly connected to the first metal frame 300. By fixing both ends of the first metal support rib 130 to the first metal frame 300, when the casing is subjected to external forces, the stress generated can be transmitted and dispersed among the first metal support rib 130, the first metal frame 300, and other parts of the upper casing 100, effectively avoiding problems such as local loosening and deformation due to weak connections, and enhancing the structural stability of the entire lighter casing. During the opening and closing of the casing, the upper casing 100 and the first metal frame 300 can maintain synchronous movement through a stable connection, avoiding jamming and misalignment caused by loose connections, and ensuring smooth opening and closing.

[0032] Specifically, the first metal support rib 130 and the first metal frame 300 are tightly connected by adhesive, welding or integral molding.

[0033] To ensure sufficient strength, the outer shell may use thicker materials or a relatively complex overall structure, leading to material waste, increased costs, and a rather monotonous overall appearance. Therefore, in one embodiment, the lower shell 200 includes a third shell 210, a fourth shell 220, and a second metal support rib 230. A second cavity is formed between the third shell 210 and the fourth shell 220. The second metal support rib 230 is disposed within the second cavity and is fixedly connected to the third shell 210. The second metal support rib 230 extends to the outer surface of the fourth shell 220, and the fourth shell 220 is fixedly connected to the second metal support rib 230. The outer surface of the second metal support rib 230 is flush with the outer surface of the fourth shell 220. When the casing is subjected to external force, the second metal support rib 230 effectively disperses stress and enhances the deformation resistance of the lower casing 200. By using the support force provided by the second metal support rib 230, the material thickness of the third casing 210 and the fourth casing 220 can be appropriately reduced, thereby saving materials and reducing production costs. In terms of appearance, the second metal support rib 230 becomes a unique decorative element, breaking the monotony of the traditional casing appearance, adding a unique shape and line beauty to the lighter casing, improving the overall aesthetics of the product, and meeting consumers' demand for personalized and beautiful products.

[0034] Specifically, the second metal support rib 230 is bonded and fixed to the third housing 210 and the fourth housing 220.

[0035] In daily life, lighters are often placed on various flat surfaces, such as desktops and windowsills. When the bottom of the lower housing 200 comes into contact with the surface, friction and collisions can easily cause wear and scratches, potentially weakening the structural integrity of the lower housing 200. Therefore, in one embodiment, the lower housing 200 further includes a third metal frame 240, which is disposed at the bottom of the third housing 210 and fixedly connected to the third housing 210 and the fourth housing 220. The third metal frame 240, the third housing 210, and the fourth housing 220 together form the second cavity. The third metal frame 240 is in direct contact with the placement surface, bearing most of the friction and impact forces from the placement surface. This effectively prevents the third housing 210 and the fourth housing 220 from being worn or scratched due to direct contact with the placement surface. When the lighter is placed on a flat surface, the third metal frame 240 can increase the contact area with the placement surface, reducing the risk of the lighter slipping due to minor unevenness of the placement surface or accidental collision.

[0036] Specifically, the support strip is tightly connected to the first metal frame 300 and the bottom frame by adhesive, welding or integral molding.

[0037] The lower housing 200 is subjected to stress from compression, collisions, and opening / closing actions during daily use, which can easily lead to localized deformation and damage, affecting the protective effect on the lighter body and the overall service life of the housing. Therefore, in one embodiment, the number of second metal support ribs 230 is set to two, with each of the two second metal support ribs 230 respectively located on both sides of the third housing 210. One end of the second metal support rib 230 is fixedly connected to the second metal frame 400, and the other end of the second metal support rib 230 is fixedly connected to the third metal frame 240. By setting two second metal support ribs 230, a stable support structure is built inside the lower housing 200. When the lighter housing is subjected to external forces, such as external compression or stress changes during opening and closing, the two metal support ribs can work together to distribute the external forces more evenly, effectively avoiding stress concentration in one place and causing localized deformation and damage, thereby enhancing the structural strength and overall stability of the lower housing 200.

[0038] Specifically, the second metal support rib 230 is tightly connected to the first metal frame 300 and the upper metal frame by adhesive, welding or integral molding.

[0039] In one implementation, reference Figure 3 The first metal support rib 130 is a cross-shaped steel bar, and all four ends of the first metal support rib 130 are fixedly connected to the first metal frame 300. The number of the second metal support ribs 230 is set to four, and the four second metal support ribs 230 are respectively arranged around the third housing 210. One end of the second metal support rib 230 is fixedly connected to the second metal frame 400, and the other end of the second metal support rib 230 is fixedly connected to the third metal frame 240. The cross-shaped steel bar allows it to provide support from multiple directions, more effectively distributing external forces to various connection points and the entire first metal frame 300. Four second metal support ribs 230 are distributed around the third shell 210 and fixed to the second and third metal frames 240. The four second support ribs work together to quickly and evenly transmit external forces to the second metal frame 400 and the third metal frame 240, and then distribute them throughout the entire lower shell 200 structure. This effectively prevents local deformation and damage to the lower shell 200, significantly improves the structural strength and overall stability of the lower shell 200, and ensures that the lighter body is in a safe protective environment.

[0040] In practical use, the sharp edges of the lighter casing can easily scratch other objects when in contact with them. Therefore, in one embodiment, the outer edges of both the second casing 120 and the fourth casing 220 are rounded. By rounding the edges, the appearance lines become smoother and softer, the overall shape appears more refined and beautiful, and wear and paint chipping caused by sharp edges are avoided during use. The rounded corner design also prevents accidental injury from accidentally hitting the edges, providing a safer user environment and improving user comfort and sense of security.

[0041] During prolonged and frequent use, the lighter case is prone to wear and deformation. Therefore, in one embodiment, the first metal frame 300, the second metal frame 400, the third metal frame 240, the first metal support rib 130, and the second metal support rib 230 are all made of metal. Metal itself has high strength and hardness, enabling it to better withstand various external forces. For example, when the lighter case is subjected to pressure, impact, or frequent opening and closing, these metal components can effectively resist deformation, maintain the integrity of their structure, greatly enhance the structural strength of the entire lighter case, ensure its long-term stable protection of the lighter, extend the case's service life, and reduce the frequency of replacement due to component damage. Metal also has a unique texture, such as luster and feel, which adds a touch of refinement and high-end quality to the lighter case, making it stand out in appearance and satisfying consumers' pursuit of product aesthetics and quality. This enhances the product's competitiveness in the market and better meets the needs of different consumer groups for personalized, high-quality lighter cases.

[0042] Specifically, the metal material is one or more of copper, silver, gold, and alloys.

[0043] A lighter that is too heavy can negatively impact the user experience. Therefore, in one embodiment, the first housing 110, the second housing 120, the third housing 210, and the fourth housing 220 are all made of non-metallic materials. Non-metallic materials are generally lighter than metallic materials, and using these materials to manufacture the four housings can significantly reduce the overall weight of the lighter. Non-metallic materials also offer a wide range of colors and textures, and can be processed through various techniques, providing lighters with more diverse appearance options to meet the aesthetic needs of different consumers. Some non-metallic materials have a soft, warm feel, which can improve the user's experience when holding the lighter.

[0044] Specifically, the non-metallic material is one or more of the following: ox horn, shell, wood, mineral, glass, resin, plastic, rubber, genuine leather, and imitation leather.

[0045] A lighter comprising a lighter housing as described in any of the preceding claims.

[0046] By equipping the lighter with the aforementioned lighter casing, the lighter receives more comprehensive and effective protection. The various components within the casing, such as the first metal frame 300, the second metal frame 400, the third metal frame 240, the first metal support rib 130, and the second metal support rib 230, work together to enhance the overall structural strength, ensuring the integrity of key components such as the internal ignition device and extending the lighter's lifespan. The lighter casing also boasts a unique design; the metal frames and support ribs, made of metallic materials, offer a distinctive texture, making the lighter's overall appearance more refined and aesthetically pleasing. This breaks away from the traditionally simple and rough image of lighters, showcasing high quality and satisfying consumers' pursuit of aesthetics and sophistication, making it more attractive among numerous lighter products.
