Atomizing head, atomizing device and electronic cigarette
An atomizing head is disclosed, including a heating component, a liquid absorption component and at least one contact ring, wherein the liquid absorption component is wrapped around the outer circumference of the heating component, the contact ring includes a base and a first clamping flange extending at a certain angle from an circumferential edge of the base, the base covers one end of the heating component in an axis direction of the heating component, the first clamping flange presses against an outer surface of the liquid absorption component to fasten the liquid absorption component onto the heating component. During the assembling process of the atomizing head, it only requires the liquid absorption component to wrap around the heating component and be pressed against and fastened by the contact ring.
