FLINT IGNITION MECHANISM OF BUTTON TYPE MADE WITH POSSIBILITY OF AUTOMATIC RETURN Russian patent published in 2017 - IPC F23Q2/16 F23Q2/46 

FIELD: power industry.

SUBSTANCE: flint ignition mechanism of the button type is made to automatically return to its initial position, wherein the mechanism comprises: a built-in flint, a steel wheel adjacent to the flint, an energy storage element which stores energy by deformation, a drive wheel rotating in the same direction with the steel wheel, when the energy storage element releases energy, the wheel axle around which the drive wheel rotates, a drive element which is ejected by the energy storage element when the energy storage element releases energy, an engaging portion disposed on the drive element which can move the drive wheel to rotate the drive wheel, a locking element which can block the movement of the drive element, a movable element which is linearly movable backward and forward within the mechanism and can compress the energy storage element to create an elastic deformation in the latter, and a return element which can push the movable element for returning to the initial position, wherein, when the energy storage element finishes releasing energy, projections of the engaging portion and the drive wheel on a plane perpendicular to the direction of the movable element movement do not overlap.

EFFECT: invention ensures ease of fabrication, low manufacturing cost.
