Atomizer and electronic atomization apparatus

Abstract

An atomizer includes: a liquid storage housing; and a first end cap provided in the liquid storage housing. A liquid storage space and an airflow channel are formed in the liquid storage housing, and one end of the liquid storage space is covered by the first end cap. At least one capillary channel is provided on the first end cap, the at least one capillary channel being separately in communication with the airflow channel and the liquid storage space.

What is claimed is: 
     
         1 . An atomizer, comprising:
 a liquid storage housing; and   a first end cap provided in the liquid storage housing,   wherein a liquid storage space and an airflow channel are formed in the liquid storage housing, and one end of the liquid storage space is covered by the first end cap, and   wherein at least one capillary channel is provided on the first end cap, the at least one capillary channel being separately in communication with the airflow channel and the liquid storage space.   
     
     
         2 . The atomizer of  claim 1 , wherein the airflow channel comprises a first airflow channel and a second airflow channel that are in communication with each other,
 wherein the liquid storage space surrounds a periphery of the second airflow channel,   wherein the first end cap is provided between the first airflow channel and the liquid storage space, and   wherein the at least one capillary channel communicates the first airflow channel with the liquid storage space.   
     
     
         3 . The atomizer of  claim 2 , wherein the liquid storage housing comprises a housing and a suction nozzle that are connected,
 wherein the second airflow channel and the liquid storage space are formed inside the housing,   wherein the first airflow channel is formed inside the suction nozzle, and   wherein the first end cap is provided between the housing and the suction nozzle.   
     
     
         4 . The atomizer of  claim 1 , wherein the first end cap comprises a first surface facing away from the liquid storage space, a second surface facing toward the liquid storage space, and a through hole running through the first surface and the second surface, and
 wherein the through hole is in communication with the airflow channel, and   wherein each capillary channel of the at least one capillary channel is distributed on a hole wall surface of the through hole and the second surface.   
     
     
         5 . The atomizer of  claim 4 , wherein a plurality of first bosses protruding in a direction close to a central axis of the through hole are provided at intervals on the hole wall surface of the through hole, and
 wherein a capillary channel of the at least one capillary channel distributed on the hole wall surface of the through hole is formed between adjacent first bosses of the plurality of first bosses.   
     
     
         6 . The atomizer of  claim 4 , wherein a plurality of second bosses provided at intervals are formed on the second surface, and
 wherein a capillary channel of the at least one capillary channel distributed on the second surface is formed between adjacent second bosses of the plurality of second bosses.   
     
     
         7 . The atomizer of  claim 6 , wherein a plurality of third bosses provided at intervals are formed on the second surface, the plurality of third bosses being distributed on a periphery of each second boss of the plurality of second bosses, and
 wherein a groove in communication with the at least one capillary channel is formed between the plurality of third bosses and each second boss.   
     
     
         8 . The atomizer of  claim 4 , wherein the through hole comprises a first portion and a second portion that are in communication with each other,
 wherein a cross-sectional area of the first portion is greater than a cross-sectional area of the second portion,   wherein the first portion is farther away from the liquid storage space than the second portion, and   wherein the at least one capillary channel is partially provided on the hole wall surface of the second portion.   
     
     
         9 . The atomizer of  claim 1 , wherein the atomizer further comprises a liquid storage member provided in the liquid storage space, the first end cap contacting the liquid storage member, or
 wherein the atomizer further comprises a liquid storage member provided in the liquid storage space, the first end cap being spaced apart from the liquid storage member, and/or   wherein the at least one capillary channel comprises a capillary groove, and/or   wherein the at least one capillary channel has a width of 0.3 mm to 1 mm.   
     
     
         10 . An electronic atomization apparatus, comprising:
 the atomizer of  claim 1 ; and   a power supply apparatus connected to the atomizer.
