1. An automatically locking, releasable, safety knob assembly, comprising:
a base configured to mount to a stove surface of a stove, the base comprising:
a disk portion;
an outer peripheral sidewall; and
an inner peripheral sidewall, the inner peripheral sidewall comprising a locking notch;

an adapter configured to mate with a valve stem of the stove extending through the base, the adapter comprising:
a head;
a tubular middle section;
an adapter base; and
an adapter central aperture extending through the adapter base, the tubular middle section, and the head, the adapter central aperture configured to receive the valve stem of the stove; and

a knob comprising:
a knob housing;
a housing disk covering the base, the housing disk comprising:
an arm movement channel aligned with the locking notch when the safety knob assembly is in a locked configuration; and
a housing disk central aperture, the housing disk central aperture configured for receiving the head of the adapter; and

an automatically locking, releasable, sub-assembly, comprising:
a slidable button configured to allow free rotation of the knob when the safety knob assembly is in an unlocked configuration; and
an automatic locking arm resiliently biased with the slidable button;

wherein engagement of the slidable button causes the automatic locking arm to disengage from the locking notch and further causes the automatic locking arm to move in the arm movement channel causing the safety knob assembly to be in the unlocked configuration and allowing the knob to freely rotate resulting in rotating of the valve stem.
