Electronic vaporization device and vaporizer thereof

Abstract

A vaporizer includes: a liquid storage cavity; a heating assembly for heating and vaporizing an aerosol-forming substrate in the liquid storage cavity, the heating assembly including a first end surface arranged opposite the liquid storage cavity; and an isolating member having an isolating portion arranged between the heating assembly and the liquid storage cavity and covering the first end surface, the isolating member isolating the liquid storage cavity from the heating assembly.

What is claimed is: 
     
         1 . A vaporizer, comprising:

         2 . The vaporizer of  claim 1 , wherein the heating assembly comprises a liquid absorbing groove and an opening provided toward the liquid storage cavity, the opening being provided on the first end surface and in communication with the liquid absorbing groove, and
 wherein the isolating portion covers the opening.   
     
     
         3 . The vaporizer of  claim 2 , wherein the isolating portion comprises a covering surface, and
 wherein a size of the covering surface is greater than a maximum size of the opening.   
     
     
         4 . The vaporizer of  claim 2 , wherein the isolating member further comprises a liquid guide structure arranged on the isolating portion. 
     
     
         5 . The vaporizer of  claim 4 , wherein the liquid guide structure comprises a plurality of liquid guide holes provided at intervals, the plurality of liquid guide holes being provided through a thickness direction of the isolating portion so as to guide the aerosol-forming substrate in the liquid storage cavity to the heating assembly. 
     
     
         6 . The vaporizer of  claim 4 , further comprising:
 a vaporization shell comprising a housing and an air outlet tube arranged in the housing,   wherein a space is provided between the housing and the air outlet tube to form the liquid storage cavity, and   wherein the liquid guide structure is located in an extending direction of the air outlet tube.   
     
     
         7 . The vaporizer of  claim 1 , wherein the isolating member is in a flat plate shape. 
     
     
         8 . The vaporizer of  claim 1 , further comprising:
 a first seal member sleeved on the heating assembly,   wherein the isolating member is arranged on the first seal member.   
     
     
         9 . The vaporizer of  claim 8 , wherein the first seal member comprises a hollow structure with two run-through ends, and an inner side thereof forms an accommodating cavity configured to accommodate the heating assembly, and
 wherein the isolating member is accommodated in the accommodating cavity and is detachably mounted with the first seal member.   
     
     
         10 . The vaporizer of  claim 8 , wherein the isolating member is integrally formed with the first seal member. 
     
     
         11 . The vaporizer of  claim 1 , further comprising:
 an upper base body,   wherein the heating assembly is at least partially located in the upper base body, and   wherein the isolating member is mounted in the upper base body.   
     
     
         12 . The vaporizer of  claim 11 , further comprising:
 a second seal member,   wherein the second seal member is sleeved on the upper base body.   
     
     
         13 . The vaporizer of  claim 12 , wherein the second seal member comprises a sleeve portion and a connection portion,
 wherein the sleeve portion is sleeved on the upper base body, and   wherein one end of the connection portion is connected to the sleeve portion, extends along a side wall of the upper base body toward a direction of the heating assembly, and is connected to the isolating member.   
     
     
         14 . The vaporizer of  claim 13 , wherein the second seal member is integrally formed with the isolating member. 
     
     
         15 . The vaporizer of  claim 14 , wherein the second seal member and the upper base body form an integral structure. 
     
     
         16 . The vaporizer of  claim 12 , wherein a liquid flowing hole is provided on the upper base body, and
 wherein the isolating member is arranged in a liquid flowing direction of the liquid flowing hole.   
     
     
         17 . The vaporizer of  claim 1 , wherein a material of the isolating member comprises one or more of stainless steel, silicone, or plastic. 
     
     
         18 . The vaporizer of  claim 1 , wherein the heating assembly comprises a porous body and a heating structure, and
 wherein the porous body comprises at least one vaporization surface, the heating structure being arranged on the vaporization surface.   
     
     
         19 . An electronic vaporization device, comprising:
 the vaporizer of  claim 1 ; and   a power supply component connected to the vaporizer.
