Heating element 200 and the second heating element 300.
In some embodiments, matrix 100 is porous ceramic matrices suitable, i.e. matrix 100 is made of porous ceramic film material, therefore
In matrix 100 include a large amount of micropore and there is certain porosity, porosity can be defined as the volume of hole in object
With the percentage of material total volume in its natural state, the porosity of the matrix 100 is lower, such as the porosity of matrix 100 is
10%~20%.Meanwhile viscosity of the liquid under room temperature is larger, the value range of the viscosity can for 50mPa.S~
1200mPa.S.It is locating when entire atomizer 20 stops working since 100 porosity of matrix is lower and liquid viscosity is higher
Under normal temperature state, the on-way resistance that liquid flows in micropore increases, and liquid is difficult to even penetrate by micropore to matrix
