Abstract: An vaporizer includes an outer housing; the outer housing is internally provided with: a liquid storage chamber having an opening; a first liquid guide element having a first surface close to the liquid storage chamber in a longitudinal direction of the outer housing, and a second surface away from the first surface; the first surface sucks the liquid substrate; and the first liquid guide element is made from an organic porous material and is configured to cover the opening to seal the liquid storage chamber, such that the liquid substrate in the liquid storage chamber is substantially removed through the first liquid guide element; a second liquid guide element, configured to at least partially contact with the second surface to suck the liquid substrate; and a heating element, configured to heat at least part of the liquid substrate in the second liquid guide element to generate an aerosol.

Abstract: A vaporizer includes: an outer housing, where the outer housing is internally provided with: a liquid storage chamber; a support, constructed to at least partially define a vaporization chamber; a smoke output tube for outputting an aerosol, constructed to substantially extend in the longitudinal direction of the outer housing, where the smoke output tube has an air inlet end being in airflow communication with the vaporization chamber; and a capillary channel is defined between the air inlet end and the support, so as to transfer an aerosol condensate at the air inlet end out of the smoke output tube. For the foregoing vaporizer, the condensate at the air inlet end of the smoke output tube is transferred out of the smoke output tube through the capillary channel, so as to slow down or eliminate the phenomenon that the condensate is sucked.

Abstract: An vaporizer includes an outer housing, where the outer housing is internally provided with: a liquid storage chamber; a first liquid guide element, having a first surface and a second surface opposite to each other, where the first surface sucks a liquid substrate in the liquid storage chamber; a second liquid guide element, arranged close to the second surface of the first liquid guide element, and configured to contact with the second surface to suck the liquid substrate; a heating element, configured to heat at least part of the liquid substrate in the second liquid guide element to generate an aerosol; and an air channel providing a flowing path for air to cross the first liquid guide element and enter the liquid storage chamber in the longitudinal direction of the outer housing.

Abstract: A vaporizer includes: at least one inhalation opening; a liquid storage cavity, which is configured to store a liquid substrate; a vaporization assembly, which heats the liquid substrate to generate an aerosol; a holder, which at least partially accommodates or holds the vaporization assembly; and a vapor output pipe, which provides an airflow path for outputting the aerosol to the at least one inhalation opening. The vapor output pipe is provided with an air inlet end, which is connected to the holder in a fit manner. A protruding structure is provided on the holder, and the protruding structure is close to the air inlet end of the vapor output pipe, so as to guide a condensate which is generated in the vapor output pipe out of the vapor output pipe through the air inlet end.

Abstract: A heater includes a metal base, having an inner surface and an outer surface; an oxide film, formed by oxidization on the inner surface of the metal base, the oxide film being configured to generate infrared rays and at least radiatively heat an aerosol generation substrate; and a heating body, provided on the outer surface of the metal base, the heating body being configured to receive electric power from a power supply to generate heat, and transfer the heat to the oxide film such that the oxide film is heated by the heat and the temperature thereof rises, to generate infrared rays. According to the present application, the heating body is adopted to heat the oxide film formed by oxidization on the surface of the metal base, such that the oxide film generates infrared rays to radiatively heat the aerosol generation substrate.
