The application is suitable for the technical field of aerosol generating devices, and provides a liquid guide assembly, an atomizing core and an atomizing device. The liquid guide assembly comprises a first liquid guide and a second liquid guide. The first liquid guide is in an annular structure and is arranged around the second liquid guide. The first liquid guide comprises a first connecting section, a liquid guide main body and a second connecting section arranged in sequence. The thickness of the first connecting section and / or the second connecting section is smaller than the thickness of the liquid guide main body. The first connecting section and the second connecting section are connected in overlap to form the annular structure of the first liquid guide. The thickness of the first connecting section and / or the second connecting section is smaller than the thickness of the liquid guide main body, so that the radial thickness of the first liquid guide at the overlap connection is reduced. Through this structural design, the radial extrusion force of the first liquid guide on the inner second liquid guide is effectively reduced, and the possibility of local invagination or deformation of the second liquid guide due to extrusion is reduced.
