Electronic atomization device and atomizer

Abstract

An atomizer includes: a liquid storage cavity; and an atomization base arranged opposite to and in fluid communication with the liquid storage cavity. An accommodation cavity is arranged in the atomization base, and an air exchange member communicating with an outside is arranged in the accommodation cavity. A first opening is arranged in the atomization base, the first opening being in airflow communication with the air exchange member and the liquid storage cavity.

What is claimed is: 
     
         1 . An atomizer, comprising:
 a liquid storage cavity; and   an atomization base arranged opposite to and in fluid communication with the liquid storage cavity,   wherein an accommodation cavity is arranged in the atomization base, and an air exchange member communicating with an outside is arranged in the accommodation cavity, and   wherein a first opening is arranged in the atomization base, the first opening being in airflow communication with the air exchange member and the liquid storage cavity.   
     
     
         2 . The atomizer of  claim 1 , further comprising:
 a seal member sleeved on the atomization base, and a gap for airflow communication with the liquid storage cavity being reserved between the seal member and the atomization base,   wherein the first opening is in airflow communication with the gap.   
     
     
         3 . The atomizer of  claim 1 , wherein the atomization base comprises an end wall arranged toward the liquid storage cavity,
 wherein the accommodation cavity has a bottom wall arranged toward the end wall,   wherein the air exchange member comprises a second opening arranged in the accommodation cavity, and   wherein a first set interval is reserved between the second opening and the bottom wall.   
     
     
         4 . The atomizer of  claim 3 , wherein a distance from the first opening to the end wall is less than a distance from the bottom wall to the end wall. 
     
     
         5 . The atomizer of  claim 3 , wherein the atomization base comprises a side wall connected to the end wall, and
 wherein the first opening is arranged on the side wall.   
     
     
         6 . The atomizer of  claim 3 , wherein the air exchange member has a minimum cross-sectional dimension at the second opening. 
     
     
         7 . The atomizer of  claim 1 , wherein the atomization base comprises an atomization cavity, and
 wherein the accommodation cavity and the atomization cavity are liquid-separately arranged from each other.   
     
     
         8 . The atomizer of  claim 1 , wherein the air exchange member comprises a columnar structure with both ends penetrating. 
     
     
         9 . The atomizer of  claim 1 , further comprising:
 an air inlet channel communicating with the outside,   wherein the air exchange member is in airflow communication with the air inlet channel.   
     
     
         10 . An electronic atomization device, comprising:
 the atomizer of  claim 1 ; and   a power supply component connected to the atomizer.   
     
     
         11 . The electronic atomization device of  claim 10 , wherein the atomizer further comprises a seal member sleeved on the atomization base, and a gap for airflow communication with the liquid storage cavity being reserved between the seal member and the atomization base, and
 wherein the first opening is in airflow communication with the gap.   
     
     
         12 . The electronic atomization device of  claim 10 , wherein the atomization base comprises an end wall arranged toward the liquid storage cavity,
 wherein the accommodation cavity has a bottom wall arranged toward the end wall,   wherein the air exchange member comprises a second opening arranged in the accommodation cavity, and   wherein a first set interval is reserved between the second opening and the bottom wall.   
     
     
         13 . The electronic atomization device of  claim 12 , wherein a distance from the first opening to the end wall is less than a distance from the bottom wall to the end wall. 
     
     
         14 . The electronic atomization device of  claim 12 , wherein the atomization base comprises a side wall connected to the end wall, and
 wherein the first opening is arranged on the side wall.   
     
     
         15 . The electronic atomization device of  claim 12 , wherein the air exchange member has a minimum cross-sectional dimension at the second opening. 
     
     
         16 . The electronic atomization device of  claim 10 , wherein the atomization base comprises an atomization cavity, and
 wherein the accommodation cavity and the atomization cavity are liquid-separately arranged from each other.   
     
     
         17 . The electronic atomization device of  claim 10 , wherein the air exchange member comprises a columnar structure with both ends penetrating. 
     
     
         18 . The electronic atomization device of  claim 10 , wherein the atomizer further comprises an air inlet channel communicating with the outside, and
 wherein the air exchange member is in airflow communication with the air inlet channel.
