         3 . The heating assembly of  claim 1 , wherein the replaceable filter mesh comprises a bottom wall, and
 wherein a plurality of first filter holes for airflow to run through are distributed on the bottom wall.   
     
     
         4 . The heating assembly of  claim 3 , wherein the bottom wall comprises a first region located at a center and a second region surrounding the first region, and
 wherein a distribution density of the plurality of first filter holes in the first region is less than a distribution density of the plurality of first filter holes in the second region.   
     
     
         5 . The heating assembly of  claim 3 , wherein a distribution density of the plurality of first filter holes on the bottom wall gradually increases from a center to a periphery. 
     
     
         6 . The heating assembly of  claim 3 , wherein the bottom wall protrudes upward to form a cylindrical protruding portion, and wherein a top wall and a side wall of the protruding portion are provided with a plurality of second filter holes for airflow to run through. 
     
     
         7 . The heating assembly of  claim 3 , wherein the replaceable filter mesh comprises a cylindrical side wall extending upward from an outer periphery of the bottom wall. 
     
     
         8 . The heating assembly of  claim 7 , wherein an airflow gap is formed between an outer wall surface of the cylindrical side wall and an inner wall surface of the vaporization cavity, and
 wherein the cylindrical side wall is provided with a plurality of third filter holes for airflow to run through.   
     
     
         9 . The heating assembly of  claim 7 , wherein a size of a cross section of the cylindrical side wall decreases from a top of the cylindrical side wall to a bottom of the cylindrical side wall. 
     
     
         10 . The heating assembly of  claim 7 , wherein the replaceable filter mesh comprises a flange extending outward from an upper outer edge of the cylindrical side wall, and
 wherein the flange abuts against an upper end surface of a heating cover.   
     
     
         11 . The heating assembly of  claim 1 , wherein the replaceable filter mesh is in a shape of a plate, and
 wherein an outer edge of the replaceable filter mesh concaves inward to form at least one groove.   
     
     
         12 . The heating assembly of  claim 1 , wherein the heating body comprises a base, a heating cover disposed on the base, and a heating element disposed between the base and the heating cover and in air communication with the vaporization cavity. 
     
     
         13 . The heating assembly of  claim 12 , wherein a heating cavity configured to place the heating element is formed between the base and the heating cover,
 wherein a diffusion cavity is formed between the heating cover and the shunt mesh, and   wherein a convergence hole communicating the heating cavity with the diffusion cavity is formed on the heating cover.   
     
     
         14 . The heating assembly of  claim 13 , wherein the shunt mesh comprises a shunt region disposed corresponding to the diffusion cavity, and
 wherein a plurality of airflow holes for airflow to run through are distributed on the shunt region,   wherein the shunt region comprises a center region located at a center of the shunt region and a peripheral region surrounding the center region, and   wherein a distribution density of the plurality of airflow holes in the center region is less than a distribution density of the plurality of airflow holes in the peripheral region.   
     
     
         15 . The heating assembly of  claim 13 , wherein a central axis of the convergence hole overlaps with a central axis of the diffusion cavity. 
     
     
         16 . A vaporization device, comprising:
 a body; and   the heating assembly of  claim 1  disposed in the body.
