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.

The utility model provides a cooling oil injection ring, a motor and a vehicle, and relates to the technical field of vehicle parts. The cooling oil injection ring comprises a first ring section and a second ring section, the first ring section and the second ring section are connected end to end to form an annular structure, the inner diameter of the first ring section is larger than that of the second ring section, the second ring section is provided with an oil duct, and an oil injection hole communicated with the oil duct is formed in the inner side wall of the second ring section. According to the cooling oil injection ring, aiming at the characteristic that the radial size of the winding end part is non-uniformly distributed in the circumferential direction, the structure of the whole oil injection ring is optimized by adopting a sectional type variable inner diameter structural design, accurate adaptation to the winding end part is realized, the trafficability of the winding end part is ensured, and the service life of the oil injection ring is prolonged. And the problem that the oil injection ring cannot be arranged due to insufficient radial thickness of the oil injection ring is also avoided.
