Combined wheel and lighter using same

Abstract

The invention relates to a combined wheel and a lighter using the same. A combined wheel of an existing lighter is prone to be assembled in the wrong direction. The combined wheel comprises a wheel body, wherein the middle parts of the two end surfaces of the wheel body are provided with a mounting hole and a mounting shaft correspondingly, the mounting hole and the mounting shaft are arranged along the axis of the wheel body, and the assembly direction of the combined wheel is identified by distinguishing the end surface outlines of the combined wheel. The mounting hole and the mounting shaftare arranged on the end surfaces of the two ends of the wheel body correspondingly, the cutter edge orientation, the reference object for judging the mounting direction of the combined wheel in the past, is replaced by the relative position relationship between the mounting hole and the mounting shaft, the identification accuracy is improved by increasing the difference of the outlines of the twoends of the wheel body, the assembly accuracy can be effectively improved, the production cost is reduced by reducing rework workload of waste products, and the assembly experience is improved.

Description

technical field [0001] The invention relates to the field of lighters, in particular to a combined wheel and a lighter using the same. Background technique [0002] Existing lighters include a casing with a fuel chamber inside and an ignition assembly for ignition. The ignition assembly can be electronic or grinding wheel ignition. The ignition assembly of the existing grinding wheel ignition method includes a rotatable combination wheel and a flint that cooperates with the combination wheel for friction and ignition. The combination wheel includes a steel wheel with a knife edge on the outer wall and side wheels coaxially arranged at both ends of the steel wheel. When in use, the user drives the steel wheel to rotate by turning the edge wheel, and the steel wheel scrapes the flint through the edge of the knife to generate sparks for ignition. [0003] During production, the steel wheel is cylindrical, and both ends of the steel wheel are flat surfaces. The steel wheel is p...

Problems solved by technology

However, this structure has the following defects: 1. Due to the small diameter difference between the large shaft and the small shaft, the contour difference between the large shaft and the small shaft is also small. The groove cavity will be unable to identify and prevent the insertion of the large shaft due to wear, resulting in the loss of the function of the flap to distinguish the direction of the combined wheel, increasing the scrap rate and requiring rework; 2. Due to the small difference in the contour of the large shaft and the small shaft, Assemblers cannot observe the difference through direct vision, so that they cannot check and correct the combination wheel that has completed the embedding of the flap. They can only verify the judgment by observing whether it can be matched with the lighter and installed and generate sparks stably. Because it cannot be done in the early assembly process Verification of the accuracy of the installation posture of the combined wheel increases the difficulty of rework and disassembly, which not only reduces production efficiency, but also easily increases production costs and scrap rates due to component damage during disassembly and rework

[0005] In addition, when the diameters of the large shaft and the small shaft differ greatly, the diameter of the small shaft is smaller, which affects the structural strength of the small shaft, and is prone to breakage due to external force, affecting the stability of use.
