Description

Technical Field

[0001] This utility model relates to the field of lighter technology, and more specifically, to a lighter that is easy to replace the flint. Background Technology

[0002] A lighter is an ignition device that uses fuel such as oil or gas. It is easy to use and portable. The ignition mechanisms of lighters are mainly divided into two categories: piezoelectric ignition and flint ignition.

[0003] Existing kerosene lighters include a base, a top cover, a wick, and an ignition mechanism. The base typically contains a fuel chamber filled with cotton. One end of the wick is located inside the fuel chamber, while the other end extends out of the base and is positioned to the side of the ignition mechanism. During use, the spark generated by the ignition mechanism ignites the wick, forming a flame for ignition. However, lighters that use flint have several drawbacks: the flint is consumed quickly, requiring tools to remove the screws for replacement, which is very troublesome; and sparks tend to fly during ignition, making it difficult to ignite successfully on the first attempt. How to invent a lighter that allows for easy flint replacement to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lighter that makes it easy to replace the flint, aiming to improve the problems of the cumbersome process of replacing the flint and the tendency of sparks to fly during ignition, making it difficult to ignite the lighter in one go.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a lighter that facilitates flint replacement, including a housing and a cover. The housing is connected to a lever and a wick, and the housing is also connected to a rotating component, a fixing component, and a sealing component. One end of the rotating component is provided with guide teeth, and the interior of the rotating component is provided with a flint and a spring. One end of the lever is provided with a limiting post, a toothed ring, and a flint wheel.

[0007] Preferably, a sealing ring is fitted onto the outer wall of the sealing component, the sealing component is threaded to the bottom end of the housing, a lever is rotatably connected to the side wall of the sealing component, and a clamping plate is fixedly connected to one end of the sealing component.

[0008] Preferably, one side of the housing is rotatably connected to a lever, one end of the lever is provided with a placement groove, the inside of the placement groove is limited and connected to one end of a limiting post, the upper end of the lever is fixedly connected to a toothed ring, the other end of the limiting post passes through the toothed ring and is connected to the fire wheel, and a rotating plate is sleeved on the outer wall of the limiting post, the rotating plate being rotatably connected to the side wall of the housing.

[0009] Preferably, the interior of the housing is rotatably connected to the rotating component, one end of the rotating component is fixedly connected to the guide teeth, and a plurality of guide teeth are provided, which are arranged in a circumferential array about the central axis of the rotating component. The guide teeth are meshed with the toothed ring, and an arc-shaped groove is provided on one side of the guide teeth.

[0010] Preferably, a mounting groove is provided on one side of the housing, the inner wall of the mounting groove is threadedly connected to a fixing member, one end of the fixing member is rotatably connected to the inner wall of the rotating member, one end of the fixing member located inside the rotating member is in contact with a spring, one end of the spring away from the fixing member is in contact with a flint, and one end of the flint abuts against the outer wall of the fire wheel.

[0011] Preferably, one end of the cotton core is located on the side where the flint and the firestone connect.

[0012] Preferably, a fire extinguishing cylinder is fixedly connected to the inner wall of the cover, and a connecting rod is fixedly connected to the inner wall of the cover. The connecting rod is located on one side of the fire extinguishing cylinder, and a piston cylinder is rotatably connected to the connecting rod. A piston rod is slidably connected to the inner wall of the piston cylinder, and one end of the piston rod is rotatably connected to the casing.

[0013] The beneficial effects of this utility model are:

[0014] When the flint wears out after prolonged use and needs to be replaced, the lever can be moved to be perpendicular to the surface of the sealing component. Then, the lever can be rotated to remove the sealing component from the bottom of the housing. After that, the clip is inserted into the surface of the fixing component to separate the fixing component from the mounting slot. The spring can then be removed and a new flint can be inserted. This method can quickly replace the flint, reduce the use of external parts, increase its functionality, and improve convenience.

[0015] In addition, during the use of the lighter, the lever can be rotated to drive the flint wheel and the toothed ring to rotate synchronously, and drive the rotating parts to rotate. Due to the friction between the flint wheel and the flint, sparks can be generated. The rotating guide teeth, through their own arc grooves, can direct the generated sparks parallel to one side of the wick, thereby ensuring that the wick is lit smoothly on the first try, avoiding sparks flying everywhere and increasing the number of times it needs to be lit, and reducing the wear and waste of the flint, thus increasing the number of times it can be used.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example, refer to Figures 1-12 A lighter that facilitates flint replacement includes a housing 1 and a cover 2. The housing 1 is connected to a lever 6 and a wick 14. The housing 1 is also connected to a rotating component 10, a fixing component 12, and a sealing component 15. One end of the rotating component 10 is provided with guide teeth 9. The interior of the rotating component 10 is provided with a flint 11 and a spring 19. One end of the lever 6 is provided with a limiting post 7, a toothed ring 8, and a flint wheel 5.

[0032] Furthermore; one side of the housing 1 is rotatably connected to the lever 6, one end of the lever 6 has a placement groove 61, the inside of the placement groove 61 is limited and connected to one end of the limiting post 7, the upper end of the lever 6 is fixedly connected to the gear ring 8, the other end of the limiting post 7 passes through the gear ring 8 and is connected to the fire wheel 5, the outer wall of the limiting post 7 is fitted with a rotating piece 18, the rotating piece 18 is rotatably connected to the side wall of the housing 1; the inside of the housing 1 is rotatably connected to the rotating component 10, one end of the rotating component 10 is fixedly connected to the guide teeth 9, the guide teeth 9 are provided with a plurality of teeth, the plurality of guide teeth are provided with a plurality of teeth. The guide teeth 9 are arranged in a circumferential array about the central axis of the rotating part 10. The guide teeth 9 are meshed with the toothed ring 8. An arc-shaped groove 91 is opened on one side of the guide teeth 9. One end of the cotton core 14 is located on one side of the connection between the fire wheel 5 and the flint 11. The inner wall of the cover 2 is fixedly connected to the fire extinguishing tube 3. The inner wall of the cover 2 is fixedly connected to the connecting rod 4. The connecting rod 4 is located on one side of the fire extinguishing tube 3. The connecting rod 4 is rotatably connected to the piston cylinder 17. The inner wall of the piston cylinder 17 is slidably connected to the piston rod 16. One end of the piston rod 16 is rotatably connected to the casing 1.

[0033] It should be noted that during the use of the lighter, the cover 2 can be rotated open by the action of the connecting rod 4, piston cylinder 17, and piston rod 16. Then, the lever 6 can be rotated. The outer wall of the lever 6 is provided with several anti-slip strips arranged in a circular array to ensure effective rotation and prevent slippage. At the same time as rotation, the limiting connection between the placement groove 61 and the limiting post 7, as well as the limiting connection between the limiting post 7 and the flint wheel 5, allows the flint wheel 5 and the toothed ring 8 to rotate synchronously. At this time, the meshing connection between the toothed ring 8 and the guide teeth 9 can drive the lighter to rotate. The rotating part 10 rotates, and sparks are generated due to the friction between the flint wheel 5 and the flint 11. The rotating guide tooth 9 can shoot the generated sparks parallel to one side of the cotton wick 14 through its own arc groove 91, thereby ensuring that the cotton wick 14 is successfully ignited at one time, avoiding the increase of the number of times sparks fly everywhere, reducing the wear and waste of the flint 11, and increasing its number of uses. In the initial state, the spring 19 is in a compressed state, so that during the wear and tear of the flint 11, it can be pushed to always be in contact with the side wall of the flint wheel 5 to ensure the ignition effect.

[0034] Reference Figures 8-11 Furthermore, a mounting groove 13 is provided on one side of the housing 1. The inner wall of the mounting groove 13 is threadedly connected to the fixing member 12. One end of the fixing member 12 is rotatably connected to the inner wall of the rotating member 10. The end of the fixing member 12 located inside the rotating member 10 is in contact with the spring 19. The end of the spring 19 away from the fixing member 12 is in contact with the flint 11. One end of the flint 11 abuts against the outer wall of the fire wheel 5. A sealing ring 151 is sleeved on the outer wall of the sealing member 15. The sealing member 15 is threadedly connected to the bottom end of the housing 1. A lever 152 is rotatably connected to the side wall of the sealing member 15. A clamping plate 153 is fixedly connected to one end of the sealing member 15.

[0035] It should be noted that when the flint 11 is worn out after prolonged use and needs to be replaced, the lever 152 can be moved. The lever 152 has a groove on one side to make it easy to latch up. Move the lever 152 to be perpendicular to the surface of the sealing component 15, and then rotate the lever 152 to remove the sealing component 15 from the bottom of the housing 1. Then insert the clip 153 into the surface of the fixing component 12 to separate the fixing component 12 from the mounting groove 13, and remove the spring 19 to insert the new flint 11. This can quickly replace the flint 11, reduce the use of external parts, and increase its own functionality. Finally, the fixing component 12 and the sealing component 15 are reset. Alternatively, the sealing component 15 can be removed separately to add fuel to the inside of the housing 1. The sealing ring 151 ensures the sealing of the sealing component 15 during installation and prevents the fuel from leaking.

[0036] It should be noted that the specific model and specifications need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
