Aerosol generating device

Abstract

An aerosol generating device includes a housing including an accommodating space for accommodating an aerosol generating article, and an inlet-side support positioned at an opening of the accommodating space and including at least one support body for supporting the aerosol generating article, and an inflow passage for receiving air from the outside of the housing, the inflow passage decreasing in width toward the inside of the accommodating space.

1 . An aerosol generating device comprising:
 a housing including an accommodating space configured to accommodate an aerosol generating article; and   an inlet-side support positioned at an opening of the accommodating space and including at least one support body configured to support the aerosol generating article, and an inflow passage configured to receive air from outside of the housing, the inflow passage decreasing in width toward an inside of the accommodating space.   
     
     
         2 . The aerosol generating device of  claim 1 , wherein a size of the inflow passage decreases toward the inside of the accommodating space in a longitudinal direction of the housing. 
     
     
         3 . The aerosol generating device of  claim 2 , wherein at least one side wall of the inflow passage in a peripheral direction of the accommodating space extends in the longitudinal direction of the housing and is inclined in the peripheral direction of the accommodating space. 
     
     
         4 . The aerosol generating device of  claim 3 , wherein the at least one side wall is curvedly inclined. 
     
     
         5 . The aerosol generating device of  claim 1 , wherein a plurality of support bodies are arranged, and the inflow passage has a concave shape between adjacent support bodies and is opened toward the aerosol generating article. 
     
     
         6 . The aerosol generating device of  claim 1 , wherein the inflow passage has a shape bent in a peripheral direction of the accommodating space while extending in a longitudinal direction of the housing, and the inflow passage is configured to allow air flowing along the inflow passage to surround the aerosol generating article and flow in a swirl pattern. 
     
     
         7 . The aerosol generating device of  claim 1 , wherein, in a longitudinal direction of the housing, a length in which an opening of the inflow passage facing the outside of the housing extends in a peripheral direction of the accommodating space is greater than a length in which a portion of the inflow passage, the portion being positioned in the inside of the accommodating space, extends in the peripheral direction of the accommodating space. 
     
     
         8 . The aerosol generating device of  claim 1 , wherein the inflow passage comprises an upper end portion facing the outside of the housing and a lower end portion facing the inside of the accommodating space in a longitudinal direction of the housing, and a width of the upper end portion is less than a width of the lower end portion in a radial direction of the accommodating space. 
     
     
         9 . The aerosol generating device of  claim 8 , wherein the width of the inflow passage decreases discontinuously. 
     
     
         10 . The aerosol generating device of  claim 8 , wherein the width of the inflow passage decreases non-linearly. 
     
     
         11 . The aerosol generating device of  claim 1 , wherein a plurality of support bodies are arranged in a peripheral direction of the accommodating space to be in contact with an outer side of the aerosol generating article, and the inflow passage is between adjacent support bodies. 
     
     
         12 . The aerosol generating device of  claim 11 , wherein a size of at least one of the plurality of support bodies increases toward the inside of the accommodating space from the outside of the housing in a longitudinal direction of the housing. 
     
     
         13 . The aerosol generating device of  claim 12 , wherein a side wall of at least one of the plurality of support bodies in the peripheral direction of the accommodating space extends in the longitudinal direction of the housing and is inclined toward the peripheral direction of the accommodating space. 
     
     
         14 . The aerosol generating device of  claim 11 , wherein a length in which a lower end portion of the at least one support body, the lower end portion facing the inside of the accommodating space in a longitudinal direction of the housing, extends in the peripheral direction of the accommodating space is greater than a length in which an upper end portion of the at least one support body, the upper end portion facing the outside of the housing, extends in the peripheral direction of the accommodating space. 
     
     
         15 . The aerosol generating device of  claim 11 , wherein each of the plurality of support bodies comprises an upper end portion facing the outside of the housing and a lower end portion facing the inside of the accommodating space in a longitudinal direction of the housing, and a thickness of the upper end portion is less than a thickness of the lower end portion in a radial direction of the accommodating space.
