Atomizer and electronic cigarette

Abstract

An atomizer and an electronic cigarette are disclosed. The atomizer includes a shell defining a smoke outlet communicating with outside environment, a liquid cavity capable of storing a fluid to be vaporized and an atomizing chamber. A heating assembly located inside the shell, wherein the heating assembly comprises a liquid guiding member, a cover and a heating component. The cover is an integral structure defining a liquid tunnel and a smoke tunnel, the liquid tunnel communicates with the liquid cavity and extends to the liquid guiding member, and the smoke outlet communicates with the atomizing chamber via the smoke tunnel. The liquid guiding member is configured to transport the fluid from the liquid tunnel to the atomizing chamber, and to heat the fluid to generate smoke. The heating component is connected with the liquid guiding member to heat the liquid guiding member.

         4 . The heating assembly of  claim 1 , wherein the one or more air entering holes include a central air entering hole surrounded by multiple surrounding air entering holes. 
     
     
         5 . The heating assembly of  claim 4 , wherein the multiple surrounding air entering holes include six surrounding air entering holes. 
     
     
         6 . The heating assembly of  claim 2 , wherein the first wall defines an arced surface, wherein the one or more air entering holes are formed on the arced surface, and wherein a height of the second wall is higher than a vertex of the arced surface. 
     
     
         7 . The heating assembly of  claim 2 , wherein the second wall defines a slot configured to fix a cover connected to and supported by the chassis.  
     
     
         8 . The heating assembly of  claim 7 , wherein the second wall defines an upper part and a lower part, and wherein the slot is on the upper part. 
     
     
         9 . The heating assembly of  claim 8 , wherein the upper part defines a recession relative to the lower part. 
     
     
         10 . The heating assembly of  claim 1 , further comprising a cover supported by the chassis, and wherein the cover includes one or more protruding parts configured to connect to the chassis. 
     
     
         11 . The heating assembly of  claim 1 , further comprising a cover supported by the chassis, wherein the cover defines a liquid tunnel and a smoke tunnel, and wherein a direction of the fluid entering the liquid tunnel is in parallel with a direction of the smoke exiting the smoke tunnel.  
     
     
         12 . A heating assembly adapted to an atomizer, comprising: 
 a chassis comprising a first wall, wherein the first wall partially defines an installation space, wherein the first wall defines multiple air entering holes extending therethrough and communicating with the installation space;    a liquid guiding member supported by the chassis, wherein the liquid guiding member comprises a top surface and a bottom surface; and    a heating component disposed in the installation space and arranged on the bottom surface, wherein the heating component is configured to heat fluid to generate smoke in the installation space.   
     
     
         13 . The heating assembly of  claim 12 , wherein a direction of air exiting the heating assembly is perpendicular to the top surface or forms an angle with the top surface.  
     
     
         14 . The heating assembly of  claim 12 , wherein the top surface is configured to receive the fluid. 
     
     
         15 . The heating assembly of  claim 12 , wherein the chassis further comprises a second wall integrated with the first wall. 
     
     
         16 . The heating assembly of  claim 15 , wherein the first wall is a bottom wall, and wherein the second wall is a side wall. 
     
     
         17 . The heating assembly of  claim 12 , wherein the multiple air entering holes include a central air entering hole surrounded by multiple surrounding air entering holes. 
     
     
         18 . The heating assembly of  claim 17 , wherein the multiple surrounding air entering holes include six surrounding air entering holes. 
     
     
         19 . The heating assembly of  claim 15 , wherein the first wall defines an arced surface, wherein the multiple air entering holes are formed on the arced surface, and wherein a height of the second wall is higher than a vertex of the arced surface. 
     
     
         20 . The heating assembly of  claim 12 , wherein a part of the liquid guiding member is located within the installation space.
