Abstract

A push-button type flint ignition mechanism that is capable of automatic reset, including: a built-in flint, a grinding wheel abutting the flint, an energy storage member that stores energy through deformation, a driving wheel rotating in the same direction as the grinding wheel when the energy storage member releases energy, a wheel axle about which the driving wheel rotates, a driving body pushed by the energy storage member when the energy storage member releases energy, a plucking portion located on the driving body and capable of plucking the driving wheel to make the driving wheel rotate, a blocking member capable of blocking the movement of the driving body, a moving member capable of making linear movements back and forth inside the mechanism and capable of squeezing the energy storage member to cause elastic deformation in the latter, and a reset member capable of pushing the moving member to reset; wherein, when no external force is exerted on the mechanism, the projections of the plucking portion and the driving wheel, respectively onto the plane perpendicular to the direction of movement by the moving member, do not overlap. Moreover, and optionally, when the energy sto…
