Description

Technical Field

[0001] This utility model relates to the field of lighter technology, specifically to a lighter housing structure and a lighter. Background Technology

[0002] A fuel lighter is a small, portable ignition tool that uses fuel as fuel and ignites it through a mechanical device to produce a spark, thereby creating a flame. It is typically made of metal or plastic and contains a fuel reservoir, an ignition device, and a control component for adjusting the flame size. For example, Chinese Patent CN223005008U discloses a lighter using a porous glass wick; the user simply rotates the flint wheel to easily ignite the flame.

[0003] Currently, traditional fuel lighters typically have a fuel filling hole at the bottom of the casing, with a flint inside. The filling hole is sealed with a plug, but the plug is exposed. Unless the plug is threaded into the filling hole, it is prone to falling off, causing kerosene leakage. However, machining threads on the plug and filling hole increases production costs. Furthermore, the flint, being a consumable, wears down gradually. Once worn, the user must purchase a new flint and replace it. Before a new flint is available, the user cannot continue using the lighter, resulting in poor usability. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a lighter housing structure and a lighter.

[0005] To achieve the aforementioned objective, this utility model provides a lighter housing structure, including an outer shell. The bottom of the outer shell is provided with an oil filling hole communicating with an oil chamber. A plug is provided inside the oil filling hole. A support device is provided at the bottom of the outer shell. The support device includes a cover plate disposed at the bottom of the outer shell. The cover plate is movably connected to the outer shell. During the movement of the cover plate, a viewing opening is formed. The viewing opening selectively corresponds to the position of the plug.

[0006] Furthermore, a flint is provided at the bottom of the outer casing, and the viewing port selectively corresponds to the position of the plug and / or flint.

[0007] Furthermore, the cover plate can be interference-fitted with the bottom of the plug.

[0008] Furthermore, the bottom of the outer casing is provided with a groove for the cover plate to slide laterally.

[0009] Furthermore, the bottom of the outer casing is provided with a positioning device for positioning the cover plate.

[0010] Furthermore, the positioning device includes a mounting groove at the bottom of the housing, an elastic element installed in the mounting groove, a positioning block movably installed in the mounting groove and connected to the elastic element, and a positioning hole on the cover plate, wherein the bottom end of the positioning block can be inserted into the positioning hole.

[0011] Furthermore, the cover plate surface is provided with a limiting groove, and the positioning block can slide within the limiting groove after the elastic element is compressed.

[0012] In another aspect, this utility model provides a lighter, including a lighter body, wherein the lighter body includes the aforementioned lighter shell structure.

[0013] The technical solution provided by this utility model has at least the following technical effects: The lighter casing structure disclosed in this utility model features a support device at the bottom of the casing. This device effectively supports the filler plug via a cover plate, preventing it from falling out of the filler hole and concealing the filler plug and flint, thus preserving the overall integrity of the lighter's exterior. Furthermore, a spare flint is hidden at the bottom of the casing; users can easily replace the spare flint or refill the lighter by simply sliding the cover plate, greatly improving ease of use.

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model. Example 1:

[0018] like Figures 1-3 As shown, this embodiment discloses a lighter housing structure, including an outer shell 1. The outer shell 1 has an oil chamber for storing fuel. The bottom of the outer shell 1 is provided with a spare new flint 2 and an oil filling hole 3 communicating with the oil chamber. A plug 4 is installed inside the oil filling hole 3. The plug 4 can be made of metal or rubber, and a sealing ring is fitted on the plug 4 to ensure the sealing of the oil chamber. Alternatively, an oil wick can be placed in the groove where the spare flint 2 is stored.

[0019] The bottom of the outer casing 1 is also provided with a support device, which includes a cover plate 5 disposed at the bottom of the outer casing 1, and the cover plate 5 is movably connected to the outer casing 1. Specifically, in this embodiment, the bottom of the outer casing 1 is provided with a sliding groove 6 for the cover plate 5 to slide laterally. The cover plate 5 can slide within the sliding groove 6, forming a viewing opening during the sliding process. This viewing opening can selectively correspond to the position of the plug 4 and / or the flint 2. By sliding the cover plate 5, oil can be added to the oil filling hole 3 and the flint 2 can be removed and replaced.

[0020] In this embodiment, when the cover plate 5 supports the plug 4, it forms an interference fit with the bottom of the plug 4, which increases the sliding resistance of the cover plate 5 and improves the anti-detachment effect. Example 2:

[0021] like Figures 4-6 As shown, to prevent the cover plate 5 from accidentally sliding in the groove 6, a positioning device for positioning the cover plate 5 is provided at the bottom of the outer casing 1 to achieve precise positioning of the cover plate 5. Specifically, in this embodiment, the positioning device includes a mounting groove 7 provided at the bottom of the outer casing 1, an elastic member 8 installed in the mounting groove 7, a positioning block 9 movably installed in the mounting groove 7 and connected to the elastic member 8, and a positioning hole 10 provided on the cover plate 5.

[0022] The positioning hole 10 adopts a countersunk hole structure and penetrates both the upper and lower ends of the cover plate 5. The elastic element 8 can be a spring, with its top contacting the outer shell 1 and its bottom contacting the positioning block 9. Under the elastic force of the spring, the bottom end of the positioning block 9 can be inserted into the positioning hole 10. Through the positioning action of the positioning block 9 and the positioning hole 10, the cover plate 5 is effectively prevented from accidentally sliding in the slide groove 6, thereby avoiding abnormal displacement of the cover plate 5. When it is necessary to slide the cover plate 5, simply insert a thin tool into the bottom of the positioning hole 10 and press the positioning block 9. Under the action of the spring, it will disengage from the positioning hole 10, and then the cover plate 5 can be slid. The cover plate 5 can selectively slide left and right to allow for the filling of oil into the oiling hole 3 or the removal and replacement of the flint 2. The operation is convenient.

[0023] To prevent the cover plate 5 from accidentally dislodging from the slide groove 6 during sliding, a limiting groove 11 is provided on the surface of the cover plate 5. The limiting groove 11 communicates with the positioning hole 10. When the positioning block 9 slides within the limiting groove 11, such as... Figure 7 , Figure 8 As shown, the sliding groove 6 cooperates with the positioning block 9 on both sides to achieve the limiting function and prevent the cover plate 5 from detaching from both sides of the outer shell 1. Example 3:

[0024] This embodiment discloses a lighter. The lighter's casing adopts the casing structure of Embodiment 1 or Embodiment 2 (except for the casing structure, the other structures are well known to those skilled in the art, and therefore will not be described in detail in this embodiment). Using this lighter provides higher safety and more convenient operation.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
