Description
Technical Field
[0001] The utility model relates to the technical field of lighters, in particular to a grinding wheel for lighters. Background Art
[0002] A lighter is a common ignition tool. By rotating the grinding wheel, friction is generated between the grinding wheel and the flint. After the friction between the two, the flint will produce sparks, and then the sparks will ignite the combustible gas inside the lighter to complete the ignition. Disposable lighters use piezoelectric ceramic igniters for ignition, but non-disposable lighters usually still use the friction between the grinding wheel and the flint to generate sparks for ignition.
[0003] Grinding wheels under existing technology are usually made of traditional materials and processes, and have problems such as poor wear resistance and short service life. As the most core part of the lighter, these problems will affect the overall quality and service life of the lighter. Utility Model Content
[0004] In order to solve the problems of poor wear resistance and short service life of grinding wheels in the prior art, which are the most core part of a lighter and affect the overall quality and service life of the lighter, this application provides a lighter grinding wheel, and the specific solution is as follows.
[0005] A lighter grinding wheel includes a wheel body, characterized in that: a mounting hole is opened on the wheel body, the mounting hole is set through the wheel body, the wheel body is installed on the lighter by means of the mounting hole, and a tooth-shaped protrusion is opened on the surface of the wheel body, and the tooth-shaped protrusion is arranged along the circumference of the wheel body.
[0006] By adopting the above technical scheme, the toothed protrusions on the wheel body can come into contact with the flint after rotation, and during the contact process, the toothed protrusions can generate sparks by friction with the flint, thereby realizing ignition of the lighter. During the ignition process, the toothed protrusions replace the wheel body in contact with the flint, reducing the contact area, thereby reducing the damage of the wheel body during rotation, and increasing the service life of the lighter grinding wheel. In addition, the toothed protrusions can generate sparks more stably for ignition, thereby further improving the ignition efficiency.
[0007] Optionally, the tooth-like protrusion is configured to be angular at one end for abutting against the flint.
[0008] By adopting the above technical solution, the end of the toothed protrusion that abuts the flint is set in an angular shape, which can further reduce the contact area between the flint and the toothed protrusion, and further reduce the excessive interference and damage caused by the contact between the toothed protrusion and the flint, thereby further increasing the service life of the lighter.
[0009] Optionally, the tooth-shaped protrusion is further provided with an arc-shaped inclined surface, and the arc-shaped inclined surface is arranged from the wheel body toward one end of the tooth-shaped protrusion for abutting against the flint.
[0010] By adopting the above technical solution and setting an arc-shaped inclined surface, the grinding wheel can be guided when it rotates, thereby reducing the movement of the grinding wheel along the arc-shaped inclined surface when it rotates, reducing the difficulty in rotation caused by the interference between the tooth-like protrusions and the flint, and allowing more tooth-like protrusions to contact the flint to generate sparks, thereby improving ignition efficiency.
[0011] Optionally, the inclination direction and inclination angle of the arc-shaped inclined surface are the same.
[0012] By adopting the above technical solution, the inclination angles of each arc-shaped inclined surface are the same, which can provide a smoother guiding effect for the rotation of the grinding wheel, thereby further improving the smoothness of the rotation and improving the ignition efficiency.
[0013] Optionally, a guide surface is further provided on the wheel body, and the guide surface is provided between the mounting hole and the tooth-shaped protrusion, and the guide surface is provided in an arc shape.
[0014] By adopting the above technical solution, a guide surface is provided on the wheel body, and the arc-shaped guide surface can provide a rotating contact surface for the user, thereby reducing the discomfort caused by the user contacting the toothed protrusions during rotation and improving the comfort of use.
[0015] Optionally, the tooth-shaped protrusions are arranged in multiple rows along the width direction of the wheel body.
[0016] By adopting the above technical solution and providing multiple rows of tooth-like protrusions, the number of tooth-like protrusions in contact with the flint can be further increased, thereby improving the efficiency of generating sparks by friction with the flint when the wheel body rotates, thereby further improving the ignition efficiency.
[0017] Optionally, the tooth-shaped protrusions in each column are arranged in parallel.
[0018] By adopting the above technical solution, the tooth-like protrusions are arranged in parallel, so that the tooth-like protrusions in the same row can contact the flint at the same time, thereby generating sparks through friction, increasing the probability of spark generation, and thus increasing the ignition efficiency.
[0019] Optionally, guide grooves are provided on the side walls on both sides in the width direction of the wheel body, and the guide grooves are used for being installed on a lighter.
[0020] By adopting the above technical solution and providing guide grooves on both sides of the wheel body, the deviation of the wheel body during rotation can be reduced, so that the wheel body can rotate more stably during ignition, further improving the ignition efficiency.
[0021] Optionally, a guide ball is provided in the guide groove, and the guide ball is movably connected in the guide groove, and the guide ball abuts against a component at the installation location of the lighter.
[0022] By adopting the above technical solution, a guide ball is arranged in the guide groove, and the guide ball can roll in the guide groove. By cooperating with the mounting components at the lighter, a connection can be formed to provide a guide for the rotation of the wheel body and reduce the friction during rotation, thereby further improving the convenience of rotation and improving the ignition efficiency.
[0023] In summary, this application has at least the following beneficial effects:
[0024] 1. The present application solves the problems of poor wear resistance and short service life of the grinding wheel in the prior art. As the core part of the lighter, it affects the overall quality and service life of the lighter. The present application provides a toothed protrusion on the wheel body to reduce the contact area between the wheel body and the flint, thereby reducing the damage to the wheel body surface, improving the wear resistance of the wheel body, and increasing the service life of the lighter.
[0025] 2. The present application also provides a guide groove on the wheel body and a guide ball in the guide groove that cooperates with the wheel body on the lighter. Under the guidance of the guide ball, the wheel body can rotate more stably under the guidance to reduce deviation, and can also reduce friction to a certain extent under the action of the guide ball, making ignition smoother, thereby further improving the ignition efficiency.

[0031] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0032] A lighter grinding wheel, such as Figure 1As shown, it includes a wheel body 1, a mounting hole 11 is provided on the wheel body 1, the mounting hole 11 is set through the wheel body 1, the wheel body 1 is installed on the lighter by means of the mounting hole 11, and a tooth-shaped protrusion 2 is provided on the surface of the wheel body 1, and the tooth-shaped protrusion 2 is arranged along the circumference of the wheel body 1. In specific implementation, the mounting shaft of the lighter passes through the mounting hole 11, and the wheel body 1 can be rotated with the mounting shaft as the rotation point, thereby rotating. During the rotation process, the tooth-shaped protrusion 2 on the wheel body 1 rubs against the flint on the lighter, thereby generating sparks. The tooth-shaped protrusion 2 on the wheel body 1 is integrally formed during production, and the wheel body 1 can be made of metal material or resin material as a whole, both of which have strong hardness and good wear resistance. In other embodiments, the wheel body 1 can be further frosted to further increase the friction between the grinding wheel and the flint, thereby reducing the situation where sparks cannot be generated during ignition.
[0033] like Figure 1 As shown, the tooth-like protrusion 2 is set in an angular shape at one end for contacting the flint. The tooth-like protrusion 2 is also provided with an arc-shaped inclined surface 21. The tooth-like protrusion 2 is in an arc-shaped tooth shape as a whole, and the arc-shaped inclined surface 21 is set from the wheel body 1 toward the end of the tooth-like protrusion 2 for contacting the flint, and the inclination direction and inclination angle of the arc-shaped inclined surface 21 are the same. In specific implementation, when the wheel body 1 is installed and rotated, the arc-shaped inclined surface 21 can just provide a guiding effect for the wheel body 1, and when rotating along the direction of the arc-shaped inclined surface 21, it can be used to ignite, thereby improving the smoothness of the rotation of the wheel body 1 during ignition, reducing the situation where the tooth-like protrusion 2 and the flint interfere and cannot rotate, further improving the smoothness of use, and the arc-shaped arc-shaped inclined surface 21 can further improve.
[0034] like Figure 1 As shown, multiple rows of tooth-like protrusions 2 are arranged along the width direction of the wheel body 1. Each row of tooth-like protrusions 2 is arranged in parallel. In specific implementation, each row of tooth-like protrusions 2 can contact with the flint, thereby increasing the number of tooth-like protrusions 2 contacting with the flint, thereby increasing the probability of generating sparks and improving the ignition efficiency, and each tooth-like protrusion 2 is arranged in parallel, and the arc-shaped inclined surface 21 can better guide the wheel body 1, thereby further improving the smoothness during use.
[0035] like Figure 1 As shown, the wheel body 1 is also provided with a guide surface 12, which is provided between the mounting hole 11 and the tooth-shaped protrusion 2, and is provided in an arc shape. In specific implementation, the guide surface 12 can provide support for the user's fingers when rotating, thereby improving the smoothness when rotating the lighter, and the guide surface 12 can also be directly pushed by the user to rotate the wheel body 1, thereby improving the comfort of using the lighter.
[0036] like Figure 2As shown, guide grooves 13 are provided on the side walls on both sides of the width direction of the wheel body 1, and the guide grooves 13 are used to cooperate with the installation on the lighter. A guide ball 131 is provided in the guide groove 13, and the guide ball 131 is movably connected in the guide groove 13, and the guide ball 131 abuts against the components of the lighter installation. In specific implementation, in this embodiment, a mounting groove is provided at the mounting plate of the lighter corresponding to the guide ball 131, and the guide ball 131 is embedded in the mounting groove and is limited in the mounting groove, so that during the rotation of the wheel body 1, the guide ball 131 can roll with the rotation of the wheel body 1 but is limited to the same position, thereby playing a guiding role, while reducing the friction between the lighter mounting plates, so that the rotation of the wheel body 1 is smoother. In other embodiments, the guide ball 131 can also be directly rotatably connected to the guide plate, and the guide ball 131 can also play a guiding role.
[0037] Working principle: Install the wheel body 1 at the corresponding position of the lighter, and rotate the lighter to make the toothed protrusions 2 on the wheel body 1 contact with the flint, thereby generating sparks for ignition. The toothed protrusions 2 can reduce the contact area and thus reduce the degree of wear of the wheel body 1, thereby further improving the service life of the grinding wheel and the lighter. At the same time, in order to compensate for the reduction in contact area, multiple rows of toothed protrusions 2 and arc-shaped inclined surfaces 21 are provided to reduce friction during rotation, improve smoothness, and increase the number of contacts, thereby reducing the situation where ignition cannot be achieved.
[0038] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
