Atomizer and electronic atomization device

Abstract

An atomizer includes: an aerosol-forming product having a receiving chamber formed inside, the receiving chamber receiving an aerosol-forming medium; a mouthpiece assembly mated with the aerosol-forming product; and an airflow channel comprising an air inlet channel and an air outlet channel respectively communicating with the receiving chamber. The airflow channel includes at least one branch air channel and a main air channel communicating with the at least one branch air channel. An airflow guiding surface is arranged at a joint between the at least one branch air channel and the main air channel. An angle between the airflow guiding surface and an axis of the main air channel is an acute angle.

What is claimed is: 
     
         1 . An atomizer, comprising:
 an aerosol-forming product having a receiving chamber formed inside, the receiving chamber being configured to receive an aerosol-forming medium;   a mouthpiece assembly mated with the aerosol-forming product; and   an airflow channel comprising an air inlet channel and an air outlet channel respectively communicating with the receiving chamber,   wherein the airflow channel comprises at least one branch air channel and a main air channel communicating with the at least one branch air channel,   wherein an airflow guiding surface is arranged at a joint between the at least one branch air channel and the main air channel, and   wherein an angle between the airflow guiding surface and an axis of the main air channel is an acute angle.   
     
     
         2 . The atomizer of  claim 1 , wherein the airflow guiding surface comprises a plane, and the angle between the plane and the axis of the main air channel ranges from 20° to 70°. 
     
     
         3 . The atomizer of  claim 1 , wherein the airflow guiding surface is transitionally connected to the main air channel by a circular arc surface. 
     
     
         4 . The atomizer of  claim 1 , wherein the at least one branch air channel comprises at least two branch air channels, and
 wherein the at least two branch air channels are distributed symmetrically along a circumferential direction of the main air channel.   
     
     
         5 . The atomizer of  claim 1 , wherein the air inlet channel comprises two branch air channels and the main air channel, and
 wherein the two branch air channels communicate with the receiving chamber through the main air channel.   
     
     
         6 . The atomizer of  claim 5 , wherein the main air channel at least partially extends into the receiving chamber and is arranged coaxially with the receiving chamber. 
     
     
         7 . The atomizer of  claim 5 , wherein each branch air channel of the two branch air channels comprises a first air guiding section and a second air guiding section respectively communicating with the first air guiding section and the main air channel, and
 wherein the second air guiding sections of the two branch air channels communicate with each other and are arranged symmetrically at 180°.   
     
     
         8 . The atomizer of  claim 7 , wherein the first air guiding section is flat. 
     
     
         9 . The atomizer of  claim 1 , wherein the air outlet channel comprises two branch air channels, the main air channel, and an inhalation channel formed inside the mouthpiece assembly,
 wherein the receiving chamber communicates with the main air channel, and   wherein the two branch air channels communicate with an outside through the inhalation channel.   
     
     
         10 . An electronic atomization device, comprising:
 the atomizer of  claim 1 ; and   a power supply apparatus mated with the atomizer.
