A vaporizer is disclosed. The vaporizer includes a liquid storage housing having a liquid storage cavity formed therein and a base arranged at one end of the liquid storage housing. The base includes an air inlet protruding stage that has an upper surface facing the liquid storage cavity. The upper surface is in a shape of a protrusion. The air inlet protruding stage is provided with a plurality of air inlet holes extending from the upper surface away from the liquid storage cavity.

A flavor aspirator includes: a weight-concentrated part that is provided at a position off the mouthpiece end and closer to the mouthpiece end side than to a midpoint position between the mouthpiece end and the distal end, and that accounts for at least approximately half of a total weight of the flavor aspirator. A value of (a length from the mouthpiece end to the center of gravity)/(a total length defined by a length from the mouthpiece end to the distal end) is in a range of 0.20 to 0.45.

An atomizer, producing an inhalable vapor, includes a liquid storage chamber, an air duct, and an atomizing core in the liquid storage chamber. The atomizing core includes a core shell and a liquid guiding cotton. The core shell includes a base and a housing. A sealing member is disposed between the air duct and the core shell, the sealing member includes a sealing body and a first connecting pipe extending from the sealing body facing the air duct. An elastic part is disposed on an outer wall of the first connecting pipe, the air duct abuts the sealing body, a bottom of the sealing body abuts the liquid guiding cotton, the first connecting pipe is located in the air duct, and the elastic part presses tightly against an inner wall of the air duct to provide sealing of liquid in all circumstances. An inhalation device is also disclosed.

An electronic cigarette (e-cigarette) capable of holding, heating, and quantitatively supplying a gelled electronic liquid (e-liquid) is provided. The e-cigarette includes an upper housing, a lower housing, a gel container, a press and reset mechanism, and an aerosol channel. The gelled e-liquid is supplied quantitatively to a heating chamber by manually pressing the press and reset mechanism. The user can adjust the time interval between pressing and releasing the press and reset mechanism according to the needs of the user for each inhalation by adjusting the length of the gelled e-liquid stick supplied to the heating chamber. Besides, a holder is provided therein with heating plates at different positions, and the holder also serves as a heating element. The design avoids the need to provide the heating element and the heating chamber separately, which reduces the volume of the smoking device.
