Atomizer and electronic atomization device

Abstract

An atomizer and an electronic atomization device are provided. The atomizer includes a first liquid storage tank and a second liquid storage tank. The second liquid storage tank includes first internal space configured to accommodate an atomization medium and an atomization cavity formed inside the first liquid storage tank. The second liquid storage tank includes second internal space configured to accommodate a sacrificial medium, where the second liquid storage tank is provided with a first vent hole configured to allow air to enter the second internal space. The connection channel is internally provided with a separator configured to allow the air to pass through and prevent the atomization medium and the sacrificial medium from passing through. An atomization core is arranged in the atomization cavity and configured to heat the atomization medium. A leaked liquid collecting tank is configured to collect the sacrificial medium leaked.

         2 . The atomizer of  claim 1 , wherein the second liquid storage tank is arranged on a side wall of the first liquid storage tank, the connection channel comprises a through hole formed on the side wall, and the separator is arranged in the through hole. 
     
     
         3 . The atomizer of  claim 1 , wherein the second liquid storage tank is spaced apart from the first liquid storage tank, the connection channel is connecting the second liquid storage tank to the first liquid storage tank, and the separator is arranged in the connection channel. 
     
     
         4 . The atomizer of  claim 1 , wherein the separator comprises at least one of the following: a porous polytetrafluoroethylene film, a porous carbon film, a porous polyvinylidene fluoride film, a porous expanded polytetrafluoroethylene film, and/or a carbon fiber film. 
     
     
         5 . The atomizer of  claim 1 , wherein the leaked liquid collecting tank comprises third internal space in communication with the atomization cavity and in communication with the second internal space through the first vent hole. 
     
     
         6 . The atomizer of  claim 1 , wherein flow resistance experienced by the sacrificial medium when flowing in the first vent hole is less than flow resistance experienced by the atomization medium when flowing from the first internal space to the atomization core. 
     
     
         7 . The atomizer of  claim 1 , wherein the first liquid storage tank comprises a first end and a second end that are opposite to each other, the atomization cavity is provided adjacent to the first end, and the first liquid storage tank is further provided with an airflow channel that is in communication with the atomization cavity and extends to the second end. 
     
     
         8 . The atomizer of  claim 7 , wherein the second liquid storage tank is arranged on a side wall of the first liquid storage tank between the first end and the second end, and the second liquid storage tank comprises a third end adjacent to the first end and a fourth end adjacent to the second end. 
     
     
         9 . The atomizer of  claim 8 , wherein the connection channel is provided adjacent to the second end and the fourth end, and the first vent hole is provided at the third end. 
     
     
         10 . The atomizer of  claim 9 , wherein the leaked liquid collecting tank is arranged adjacent to the first end and the third end, the leaked liquid collecting tank comprises third internal space is provided with an air inlet in communication with the atomization cavity, and is provided with a second vent hole communicating the third internal space with the atomization cavity. 
     
     
         11 . The atomizer of  claim 10 , wherein the second vent hole is provided on a side wall of the leaked liquid collecting unit adjacent to the atomization cavity or a side wall of the leaked liquid collecting unit adjacent to the air inlet. 
     
     
         12 . The atomizer of  claim 1 , further comprising a liquid absorbing member arranged in the leaked liquid collecting tank and configured to absorb the sacrificial medium.
