Atomizer and electronic atomization apparatus

Abstract

An atomizer includes: a liquid storage housing, a liquid storage cavity being formed in the liquid storage housing; a first atomization base disposed at least partially in the liquid storage housing; a second atomization base disposed in the liquid storage housing, an atomization cavity being formed between the second atomization base and the first atomization base; and an atomization core at least partially disposed in the atomization cavity. A cavity bottom surface of the liquid storage cavity comprises at least one liquid guiding surface extending axially along the atomization core. The at least one liquid guiding surface has a structure with a high middle and two low ends.

What is claimed is: 
     
         1 . An atomizer, comprising:
 a liquid storage housing, a liquid storage cavity being formed in the liquid storage housing;   a first atomization base disposed at least partially in the liquid storage housing;   a second atomization base disposed in the liquid storage housing, an atomization cavity being formed between the second atomization base and the first atomization base; and   an atomization core at least partially disposed in the atomization cavity,   wherein a cavity bottom surface of the liquid storage cavity comprises at least one liquid guiding surface extending axially along the atomization core, and   wherein the at least one liquid guiding surface has a structure with a high middle and two low ends.   
     
     
         2 . The atomizer of  claim 1 , wherein the at least one liquid guiding surface comprises a circular arc surface with a high middle and two low ends. 
     
     
         3 . The atomizer of  claim 1 , wherein the at least one liquid guiding surface comprises two planes arranged in inverted V-shape. 
     
     
         4 . The atomizer of  claim 1 , wherein the at least one liquid guiding surface comprises two liquid guiding surfaces respectively located on two radial sides of the atomization core. 
     
     
         5 . The atomizer of  claim 1 , wherein a highest position of the at least one liquid guiding surface is not higher than a highest position of the atomization core. 
     
     
         6 . The atomizer of  claim 1 , wherein a width of each liquid guiding surface of the at least one liquid guiding surface is greater than or equal to 0.5 mm. 
     
     
         7 . The atomizer of  claim 1 , wherein the second atomization base comprises a body portion and at least one liquid guiding portion protruding outward from an outer wall surface of the body portion, and
 wherein the at least one liquid guiding surface is formed on an upper surface of the at least one liquid guiding portion.   
     
     
         8 . The atomizer of  claim 7 , wherein the outer wall surface of the at least one liquid guiding portion is hermetically bonded to an inner wall surface of the liquid storage housing. 
     
     
         9 . The atomizer of  claim 1 , wherein two ends of the atomization core are in communication with the liquid storage cavity. 
     
     
         10 . An electronic atomization apparatus, comprising:
 the atomizer of  claim 1 ; and   a control circuit electrically connected to the atomizer.
