The present invention intends to provides a piezoelectric ignition lighter capable of avoiding misuse by children but maintaining excellent operability for normal users without unreasonably increasing actuation load at the initial ignition operation. For this end, the piezoelectric ignition lighter has a valve mechanism, a nozzle 3 and a piezoelectric mechanism 4 at the top of a lighter body 1 and ignites by actuation of an actuation cap 6 integrally molded of polyacetal resin with torsion plates 7,7. The torsion plates 7,7 are separated from the upper end surface 1a of the lighter body 1 by a gap equal to about 60%~90% of the actuation stroke in the non-actuated condition to provide a normal (light) actuation load at the initial actuation stage. After engagement of the torsion plates 7,7 with the upper end surface of the lighter body 1, resilient load of the torsion plates is added to normal load, thereby increasing the actuation load.

The invention discloses a timing gas cooker using piezoelectric ignition by a photocell solenoid valve coordinated with seesaw delay. The timing gas cooker is a timing gas cooker with power-free rapid flameout protection function, and mainly coordinates the sustained release effect of a sucker with the seesaw principle, so that when a piezoelectric ignition knob is pressed, a solenoid valve is opened first to temporarily keep supplying gas, and then the piezoelectric spark is produced for ignition and combustion. Photocells or thermocouples can be used for forming immediate combustion after ignition, to avoid the operation of pressing a button with hand for several seconds. A spring timing switch is arranged between the solenoid valve and the photocell or the thermocouple in series, so that the solenoid valve can be closed automatically and rapidly when time is up or accidental flameout occurs. Furthermore, every timing is just usable for one time, so that the worries that water is boiled away, a pot is burned out, and rice is overcooked can be avoided; the timing gas cooker of the invention is suitable for liquefied petroleum gas, coal gas, natural gas, biogas and other household gas cookers.
