Atomizer and electronic atomization apparatus

Abstract

An atomizer includes: a housing, a liquid storage cavity being provided in the housing; an atomization base provided in the housing, a liquid outlet hole being provided on the atomization base; and a liquid guide member at least partially provided in the liquid outlet hole. The liquid guide member has at least two liquid guide surfaces communicating the liquid storage cavity with the liquid outlet hole.

What is claimed is: 
     
         1 . An atomizer, comprising:
 a housing, a liquid storage cavity being provided in the housing;   an atomization base provided in the housing, a liquid outlet hole being provided on the atomization base; and   a liquid guide member at least partially provided in the liquid outlet hole,   wherein the liquid guide member has at least two liquid guide surfaces communicating the liquid storage cavity with the liquid outlet hole.   
     
     
         2 . The atomizer of  claim 1 , wherein the liquid guide member comprises a first liquid guide portion and a second liquid guide portion that are on a same side of the liquid guide member and are connected to each other, and
 wherein the first liquid guide portion and the second liquid guide portion are located on a same liquid guide surface of the at least two liquid guide surfaces.   
     
     
         3 . The atomizer of  claim 1 , wherein a groove is provided on an inner wall of the liquid outlet hole, one part of the liquid guide member being accommodated in the groove, and an other part of the liquid guide member protruding out of the groove and extending into the liquid storage cavity and the liquid outlet hole, and
 wherein the other part of the liquid guide member forms the at least two liquid guide surfaces.   
     
     
         4 . The atomizer of  claim 1 , wherein a groove is provided on an inner wall of the liquid outlet hole, one part of the liquid guide member being accommodated in the groove, and an other part of the liquid guide member protruding out of the groove and extending into the liquid storage cavity or the liquid outlet hole, and
 wherein the other part of the liquid guide member located forms the at least two liquid guide surfaces.   
     
     
         5 . The atomizer of  claim 3 , wherein the liquid guide member comprises a first protrusion portion in the liquid storage cavity and a second protrusion portion in the liquid outlet hole,
 wherein the first protrusion portion and the second protrusion portion each have a first liquid guide portion and a second liquid guide portion that are on a same side and are connected to each other, and   wherein the first liquid guide portion and the second liquid guide portion are located on a same liquid guide surface of the at least two liquid guide surfaces.   
     
     
         6 . The atomizer of  claim 5 , wherein the first protrusion portion and the second protrusion portion each have at least two first liquid guide portions and second liquid guide portions that are provided on a same side and are connected to each other, and
 wherein each first liquid guide portion and a corresponding second liquid guide portion are located on the same liquid guide surface.   
     
     
         7 . The atomizer of  claim 5 , wherein the first protrusion portion has a top facing away from the atomization base and a third liquid guide portion that intersects the top,
 wherein the second protrusion portion has a fourth liquid guide portion that faces away from an inner wall of the liquid outlet hole and is connected to the third liquid guide portion,   wherein the third liquid guide portion and the fourth liquid guide portion are on a same side, and   wherein the top, the third liquid guide portion, and the fourth liquid guide portion are sequentially connected to each other to form another liquid guide surface of the at least two liquid guide surfaces.   
     
     
         8 . The atomizer of  claim 7 , wherein the top is inclined to the third liquid guide portion at a downward slope. 
     
     
         9 . The atomizer of  claim 7 , wherein an intersection between the top and the third liquid guide portion comprises a chamfer. 
     
     
         10 . The atomizer of  claim 5 , wherein the first protrusion portion protrudes out of the liquid outlet hole by at least 0.1 mm in an axial direction of the liquid outlet hole. 
     
     
         11 . The atomizer of  claim 1 , wherein at least a part of the liquid guide comprises an oleophilic material. 
     
     
         12 . An electronic atomization apparatus, comprising:
 a power supply component; and   the atomizer of  claim 1 ,   wherein the power supply component is electrically connected to the atomizer.
