Description

Technical Field

[0001] This application relates to the field of lighter accessories technology, and in particular to a lighter grinding wheel. Background Technology

[0002] A lighter is a small fire-starting device widely used in daily life due to its low price, ease of use, and convenient operation. It is primarily used for starting a fire, smoking, and can also be used for cooking or other fire-starting purposes. Based on the ignition method, lighters can be divided into spark lighters and electronic lighters.

[0003] A patent document with publication number CN212511256U discloses a lighter grinding wheel. This patent describes a method where a driving lever rotates to separate the lever from the operating tube, thus separating the fixed wheel, movable wheel, and grinding wheel. Damaged grinding wheels are then replaced, and the movable and fixed wheels are installed at opposite ends of the grinding wheel. The lever and operating tube are then connected to reassemble the grinding wheel, facilitating its replacement. However, the ignition structure in this patent is relatively simple and lacks sufficient safety features. Children could easily ignite the lighter while playing, potentially leading to accidents. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a lighter grinding wheel, which overcomes the shortcomings of the prior art and aims to solve the problem that the ignition structure of lighters is relatively simple and lacks certain safety protection, making it easy for children to ignite the lighter while playing, thus easily causing safety accidents.

[0005] To achieve the above objectives, this application provides the following technical solution: a lighter grinding wheel, comprising a lighter body, wherein a lighter grinding wheel is rotatably mounted on the lighter body via a fixed rod, the lighter grinding wheel comprising a movable wheel one, a movable wheel two, and a grinding wheel, wherein a ratchet groove is formed on the outer wall of the grinding wheel near the movable wheel one, and a fixed seat adapted to the ratchet groove is fixedly mounted on the outer wall of the movable wheel one near the grinding wheel, wherein an adjustment groove is formed inside the fixed seat, a spring is fixedly connected inside the adjustment groove, and an adjustment block is fixedly mounted on the other end of the spring.

[0006] By adopting the above technical solution, a spring is set to adjust the position of the adjusting block so that it is engaged with the inner wall of the ratchet groove. Through the cooperation between the adjusting block and the ratchet groove, it is ensured that the movable wheel can only drive the grinding wheel to rotate for ignition when it rotates clockwise. Moreover, by setting the fixed seat, adjusting groove, spring and adjusting block, the resistance during rotation can be increased, making it difficult for children to rotate the movable wheel to drive the grinding wheel, which can play a safety precaution.

[0007] As a preferred embodiment of this application, the adjusting block slides inside the adjusting groove, and the outer wall of the adjusting block away from the fixed seat abuts against the inner wall of the ratchet groove.

[0008] By adopting the above technical solution, through the linkage between the adjusting block and the ratchet groove, when the adjusting block swings clockwise, it can drive the grinding wheel to rotate in the same direction. When the adjusting block swings counterclockwise, the adjusting block slides on the ratchet groove, and the grinding wheel stops rotating.

[0009] As a preferred technical solution of this application, a connecting cylinder is fixedly connected to the outer wall of the movable wheel near the grinding wheel, and one end of the connecting cylinder is inserted into the interior of the grinding wheel and threadedly connected to the fixed seat.

[0010] By adopting the above technical solution, it is possible to assemble or separate the movable wheel one, movable wheel two, and grinding wheel, making it convenient to replace the damaged grinding wheel.

[0011] As a preferred technical solution of this application, the outer walls of the movable wheel 2 and the movable wheel 1 on opposite sides are provided with rotating holes. The inner diameter of the rotating holes is adapted to the outer diameter of the fixed rod, and the inner diameter of the hole of the connecting cylinder is adapted to the outer diameter of the fixed rod.

[0012] By adopting the above technical solution, the necessary conditions are provided for installing the lighter grinding wheel on the fixed rod.

[0013] As a preferred technical solution of this application, the grinding wheel has multiple parallel grinding ridges integrally formed on its circumferential sidewall, and a gap is provided between any two adjacent grinding ridges.

[0014] By adopting the above technical solution, the grinding not only increases the friction between the grinding wheel and the flint and steel, improving the smoothness of ignition, but also enhances the structural strength of the grinding wheel itself, making it more wear-resistant.

[0015] As a preferred technical solution of this application, a flint is fixedly installed on the upper surface of the lighter body below the fixing rod, and the top of the flint fits into the bottom of the ground edge.

[0016] By adopting the above technical solution, ignition is achieved through the friction between the grinding wheel and the flint.

[0017] As a preferred technical solution of this application, multiple parallel protrusions are integrally formed on the circumferential sidewalls of the first and second movable wheels, and an anti-slip groove is provided between any two adjacent protrusions.

[0018] By adopting the above technical solution, the contact area between the user's hand and the first and second movable wheels can be increased by setting protrusions, ensuring that the user is less likely to slip during use.

[0019] As a preferred technical solution of this application, a plurality of the protrusions are provided with convex arc angles symmetrically arranged on both sides of their upper surfaces, and the vertical cross-section of the convex arc angles is arranged in an arc shape.

[0020] By adopting the above technical solution, it is ensured that the part of the finger that contacts the bump will not be scratched by the sharp edge, thus protecting the hand.

[0021] The beneficial effects of this application are:

[0022] In this invention, a spring is provided to adjust the position of the adjusting block so that it engages with the inner wall of the ratchet groove. The cooperation between the adjusting block and the ratchet groove ensures that the movable wheel can only drive the grinding wheel to rotate for ignition when it rotates clockwise. Furthermore, the fixed seat, adjusting groove, spring, and adjusting block increase the resistance during rotation, making it difficult for children to rotate the movable wheel to drive the grinding wheel, thus providing a safety precaution. The protrusions and convex arcs ensure that the contact points between the fingers and the lighter's grinding wheel are not scratched by sharp edges, thus protecting the user's hands.

[0023] With reference to the following description and accompanying drawings, specific embodiments of the present invention are disclosed in detail, indicating the ways in which the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereto. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1 - Figure 4 As shown, this embodiment provides a lighter grinding wheel, including a lighter body 1. The lighter body 1 is rotatably mounted with a lighter grinding wheel via a fixing rod 2. The lighter grinding wheel includes a movable wheel 4, a movable wheel 5, and a grinding wheel 6. A ratchet groove 7 is formed on the outer wall of the grinding wheel 6 near the movable wheel 4. A fixing seat 8 adapted to the ratchet groove 7 is fixedly installed on the outer wall of the movable wheel 4 near the grinding wheel 6. An adjustment groove 10 is formed inside the fixing seat 8. A spring 11 is fixedly connected inside the adjustment groove 10. The other end of the spring 11 is fixedly... An adjusting block 12 is fixedly installed. During use, a spring 11 is provided to adjust the position of the adjusting block 12 so that it is locked onto the inner wall of the ratchet groove 7. Through the cooperation between the adjusting block 12 and the ratchet groove 7, it is ensured that the movable wheel 4 can only drive the grinding wheel 6 to rotate for ignition when it rotates clockwise. Moreover, by setting the fixed seat 8, adjusting groove 10, spring 11 and adjusting block 12, the resistance during rotation can be increased, making it difficult for children to rotate the movable wheel 4 to drive the grinding wheel 6 to rotate, which can play a safety precaution.

[0031] In this embodiment, as Figure 4 As shown, the adjusting block 12 slides inside the adjusting groove 10, and the outer wall of the adjusting block 12 away from the fixed seat 8 abuts against the inner wall of the ratchet groove 7. In use, through the linkage between the adjusting block 12 and the ratchet groove 7, when the adjusting block 12 swings clockwise, it can push the grinding wheel 6 to rotate in the same direction. When the adjusting block 12 swings counterclockwise, the adjusting block 12 slides on the ratchet groove 7, and the grinding wheel 6 stops rotating.

[0032] In this embodiment, as Figure 2 and 3 As shown, a connecting cylinder 9 is fixedly connected to the outer wall of the movable wheel 2 5 near the grinding wheel 6. One end of the connecting cylinder 9 is inserted into the interior of the grinding wheel 6 and threadedly connected to the fixed seat 8. In use, this allows the movable wheel 1 4, movable wheel 2 5 and grinding wheel 6 to be assembled together or separated, making it convenient to replace the damaged grinding wheel 6.

[0033] In this embodiment, as Figure 2 and 3As shown, rotating holes 15 are provided on the outer walls of the opposite sides of the movable wheel 2 5 and movable wheel 1 4. The inner diameter of the rotating hole 15 is adapted to the outer diameter of the fixed rod 2. The inner diameter of the hole of the connecting cylinder 9 is adapted to the outer diameter of the fixed rod 2. In use, this provides the necessary conditions for the lighter grinding wheel to be installed on the fixed rod 2.

[0034] In this embodiment, as Figure 4 As shown, the grinding wheel 6 has multiple parallel grinding ridges 16 integrally formed on its circumferential sidewall, and there is a gap between any two adjacent grinding ridges 16. When in use, the grinding ridges 16 not only increase the friction when the grinding wheel 6 contacts the flint 3, improving the smoothness of ignition, but also improve the structural strength of the grinding wheel 6 itself, making it more wear-resistant.

[0035] In this embodiment, as Figure 1 and 4 As shown, a flint 3 is fixedly installed on the upper surface of the lighter body 1 below the fixing rod 2. The top of the flint 3 fits into the bottom of the grinding ridge 16. When in use, the flint 3 is lit by friction between the grinding wheel 6 and the flint 3.

[0036] In this embodiment, as Figure 3 As shown, multiple parallel protrusions 13 are integrally formed on the circumferential sidewalls of movable wheel 4 and movable wheel 5, and anti-slip grooves are provided between any two adjacent protrusions 13. When in use, by setting protrusions 13, the contact area between the user's hand and movable wheel 4 and movable wheel 5 can be increased, ensuring that the user is not prone to slipping when using them.

[0037] In this embodiment, as Figure 3 As shown, several protrusions 13 have symmetrically arranged convex arc angles 14 on both sides of their upper surfaces. The vertical cross-section of the convex arc angles 14 is arranged in an arc shape. During use, this ensures that the part of the finger that contacts the protrusion 13 will not be scratched by the sharp edge, thus protecting the hand.

[0038] Working principle: When using the lighter grinding wheel of this application, a spring 11 is provided to adjust the position of the adjusting block 12 so that it is engaged with the inner wall of the ratchet groove 7. Through the cooperation between the adjusting block 12 and the ratchet groove 7, it is ensured that the movable wheel 4 can only drive the grinding wheel 6 to rotate for lighting when it rotates clockwise. Moreover, by setting the fixed seat 8, adjusting groove 10, spring 11 and adjusting block 12, the resistance during rotation can be increased, making it difficult for children to rotate the movable wheel 4 to drive the grinding wheel 6 to rotate, which can play a safety role. By setting the protrusion 13 and the convex arc angle 14, it is ensured that the part of the fingers that contacts the lighter grinding wheel will not be scratched by sharp edges, thus protecting the hands.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
