6. The porous ceramic body of claim 1, wherein the closest distance of the second blind hole to the atomizing surface is greater than or equal to 1 mm.
7. The porous ceramic body of claim 1, wherein the first and second blind holes are arranged in parallel, the second blind hole extending toward the atomizing surface, the first blind hole opening on the atomizing surface and extending toward the liquid-absorbing surface.
8. The porous ceramic body of claim 1, comprising one or more of the first blind holes, each of the first blind holes being adjacent to a plurality of the second blind holes;
alternatively, the porous ceramic body includes one or more of the second blind holes, each of the second blind holes being adjacent to a plurality of the first blind holes.
9. The porous ceramic body of claim 1, wherein the first blind hole is formed near the edge of the atomization surface and is annular, the second blind hole is formed in the middle of the liquid suction surface and is cylindrical, and the first blind hole and the second blind hole are coaxial with the porous ceramic body.
10. The porous ceramic body of claim 1, wherein the sidewall surfaces of the first and second blind holes in the circumferential direction are continuous or discontinuous.
11. A heating element comprising the porous ceramic body according to any one of claims 1 to 10 and a heating element fixed to the atomizing surface.
12. An atomizer, characterized in that, including the atomizing chamber, the stock solution chamber used for storing the liquid medium, and the heating element of claim 11, the heating element is set up in the atomizing chamber and leads the liquid to connect with the stock solution chamber, the said scavenge hole communicates with the atomizing chamber; or the first blind hole is communicated with the atomization cavity, and the second blind hole is communicated with the liquid storage cavity.
13. An electronic atomizer, comprising a power supply means and the atomizer of claim 12, said power supply means being electrically connected to said atomizer.
