This utility model discloses an atomizing core and an atomizer. The atomizing core includes a porous cup body, a first heating element, and a second heating element. The porous cup body includes an inner wall surface and an outer wall surface. The inner wall surface forms a cavity for containing the atomizing medium. At least a portion of the first heating element is disposed on the inner wall surface. The first heating element is used to preheat the atomizing medium in the cavity. The second heating element is disposed on the outer wall surface and is used to heat and atomize the atomizing medium seeping from the outer wall surface. The first heating element preheats the atomizing medium in the cavity, causing it to melt into an atomizing liquid. The atomizing liquid seeps out through the porous cup body to the outer wall surface. The second heating element heats and atomizes the seeping atomizing liquid to generate an aerosol. The preheating of the first heating element allows for a timely and stable supply of atomizing liquid to the second heating element, ensuring that the second heating element has sufficient contact with the atomizing liquid during the heating process. This effectively prevents the second heating element from dry burning and avoids core scorching.
