  • Patent number: 11800895
    Abstract: A vaporizer comprises an absorber and a heating element. The absorber is configured to absorb the material to be vaporized and comprises a plurality of first pores of a 100-500 nm diameter and a plurality of second pores of a 20-100 nm diameter. A ratio of the number of the second pores N2 to the number of the first pores N1 in a unit area, i.e., N2/N1, is 10-50%. The heating element heats and vaporizes the material to be vaporized in the absorber.
    Type: Grant
    Filed: April 9, 2020
    Date of Patent: October 31, 2023
