1. A liquid storage assembly for an atomizer, the atomizer comprising an atomizing core assembly having an outer wall, the outer wall having a liquid inlet, the liquid storage assembly comprising:
a housing, defining a liquid storage cavity and a first assembling hole and comprising a base, wherein the base is disposed at an end of the liquid storage cavity away from the first assembling hole, wherein the first assembling hole is configured to receive an end of the atomizing core assembly;
an inner wall, arranged in the liquid storage cavity, configured to sleeve around the atomizing core assembly, wherein a capillary gap is defined between the inner wall and an outer wall of the atomizing core assembly, a gap communicating with the capillary gap is defined between a portion of the base located at the end of the liquid storage cavity and an end of the inner wall facing the base, and the capillary gap is configured to guide liquid in the liquid storage cavity to flow from the gap to pass through the liquid inlet.
 
19. An atomizer, comprising:
an atomizing core assembly, having an outer wall and the outer wall defining a liquid inlet; and
a liquid storage assembly comprising:
a housing, defining a liquid storage cavity and a first assembling hole and comprising a base, wherein the base is disposed at an end of the liquid storage cavity away from the first assembling hole, wherein the first assembling hole is configured to receive an end of the atomizing core assembly; and
an inner wall, arranged in the liquid storage cavity, configured to sleeve around the atomizing core assembly, wherein a capillary gap is defined between the inner wall and the outer wall of the atomizing core assembly, a gap communicating with the capillary gap is defined between a portion of the base located at the end of the liquid storage cavity and an end of the inner wall facing the base, and the capillary gap is configured to guide liquid in the liquid storage cavity to flow from the gap to pass through the liquid inlet;
wherein the atomizing core assembly is arranged in the liquid storage cavity,
when liquid level in the liquid storage cavity is lower than a position of the liquid inlet, liquid in the liquid storage cavity enters the liquid inlet along the capillary gap.
 
20. An electronic atomizing device comprising:
a body component; and
an atomizer comprising:
an atomizing core assembly, having an outer wall and the outer wall defining a liquid inlet; and
a liquid storage assembly comprising:
a housing, defining a liquid storage cavity and a first assembling hole and comprising a base, wherein the base is disposed at an end of the liquid storage cavity away from the first assembling hole, wherein the first assembling hole is configured to receive an end of the atomizing core assembly, and
an inner wall arranged in the liquid storage cavity, configured to sleeve around the atomizing core assembly, wherein a capillary gap is defined between the inner wall and the outer wall of the atomizing core assembly, a gap communicating with the capillary gap is defined between a portion of the base located at the end of the liquid storage cavity and an end of the inner wall facing the base, and the capillary gap is configured to guide liquid in the liquid storage cavity to flow from the gap to pass through the liquid inlet;
wherein the atomizing core assembly is arranged in the liquid storage cavity, when liquid level in the liquid storage cavity is lower than a position of the liquid inlet, liquid in the liquid storage cavity enters the liquid inlet along the capillary gap;
wherein the body component is electrically connected to the atomizer to supply power to the atomizer.
