Abstract: A vaporizer includes: a liquid storage cavity; a liquid guide element, configured to extend in a direction perpendicular to a longitudinal direction of the vaporizer and to be in fluid communication with the liquid storage cavity to suck a liquid substrate; a heating element, at least partially surrounding the liquid guide element and used for heating at least part of the liquid substrate in the liquid guide element to generate an aerosol; a vaporization chamber, at least partially surrounding the heating element; and liquid temporary storage spaces, configured to at least partially surround the liquid guide element and avoid the heating element, and configured to store the liquid substrate to adjust efficiency of transferring the liquid substrate to the heating element. The liquid temporary storage spaces keep saturation of the liquid substrate in the liquid guide element in a suitable state, thus eliminating or slowing down oil frying.

Abstract: An e-cigarette cartridge includes a housing with an air inlet and an air outlet; and the housing is provided with a liquid storage cavity, a porous body, a vaporization cavity, a heating element, a support frame, and a vapor output channel, where the vaporization cavity is in airflow communication with the air inlet; the support frame is constructed to provide the porous body with support and holding; and the vapor output channel includes a first channel part and a second channel part that are formed on the support frame and extend in a width direction of the housing. One end of the first channel part is in communication with the vaporization cavity and the other end is in communication with the air outlet; one end of the second channel part is in airflow communication with the vaporization cavity and the other end is in airflow communication with the air outlet.

Abstract: Provided are an atomizer of an electronic cigarette, and the electronic cigarette. The atomizer comprises a liquid storage chamber for storing a liquid matrix; an air channel, which provides a flow path for allowing external air to enter the liquid storage chamber and has a communication port for allowing external air to enter the liquid storage chamber; and a sealing element comprising a shielding portion that shields the communication port. The shielding portion can open at least part of the communication port in response to a negative pressure change in the liquid storage chamber to allow external air to enter the liquid storage chamber.

Abstract: A vaporizer includes a liquid storage cavity for storing a liquid substrate; a porous body in fluid communication with the liquid storage cavity to receive the liquid substrate; a heating element combined with the porous body to heat the liquid substrate to generate an aerosol; a holder to hold the porous body; and a seal element, arranged between the holder and the porous body to seal a gap between the holder and the porous body, where the seal element includes a plurality of side walls surrounding the porous body along a circumferential direction of the porous body and an upper end wall. The seal element includes convex ribs extending on outer surfaces of the plurality of side walls and the upper end wall or on inner surfaces of the plurality of side walls and the upper end wall, and the convex ribs are connected into at least one closed ring.

Abstract: The present application discloses a heater and a smoking device including the heater. The heater includes a heating body, in which a space for containing an aerosol-forming matrix, configured to receive electric power from a power supply to generate heat, and transfer the heat to the aerosol-forming matrix so as to volatilize at least one component in the aerosol-forming matrix; an electrode part including a first electrode and a second electrode arranged on the heating body at intervals and electrically connected with the heating body, configured to feed the electric power to the heating body; and an electrode connector including an abutting part and an extension part; the abutting part abutting against the electrode part to be electrically connected with the electrode part, and the extension part being configured to extend the electrode part to a position far away from the heating body through electrical connection.
