Abstract: A vaporizer includes: a shell; a support arranged in the shell, a liquid storage cavity being defined between the support and the shell; a vaporization assembly arranged on the support for heating and vaporizing an aerosol-forming substrate; and a preheating member, the preheating member having a first end mounted to the support and thermally connected to the vaporization assembly and a second end extending into the liquid storage cavity.

Abstract: A vaporizer includes: a liquid storage housing; a vent tube arranged in the liquid storage housing, a liquid storage cavity being formed between an inner surface of the liquid storage housing and an outer surface of the vent tube; and a piston sealingly arranged between the inner surface of the liquid storage housing and the outer surface of the vent tube, the piston having a first surface and a second surface arranged opposite each other, the first surface being in communication with atmosphere, the second surface being in communication with the liquid storage cavity. The piston is movable in the liquid storage housing under air pressure of the atmosphere so as to change a volume of the liquid storage cavity.

Abstract: A heating wire of an electronic atomizing device includes a central end, a distal end, and a plurality of spiral heating coils extending between the central end and the distal end. The plurality of spiral heating coils is coplanar and surrounds the central end. A mounting gap is formed between any two adjacent spiral heating coils in an extending direction of a reference line connecting the center end and the distal end. The widths of the mounting gaps gradually decrease along the extending direction of the reference line away from the central end. An electronic atomizing device including the aforementioned heating wire is further provided.

Abstract: The invention discloses an electronic atomizing device and an atomizer thereof. The atomizer includes a main body unit and a suction nozzle unit. The main body unit includes a liquid storage cavity, an atomization assembly fluidly connected to the liquid storage cavity and a first pipe fluidly connected to the atomization assembly. The liquid storage cavity includes a liquid injection port. The suction nozzle unit is detachably disposed on an upper end of the first pipe and seals the liquid injection port. The suction nozzle unit includes a second pipe, an operating member and an elastic member. The second pipe is detachably screwed to the first pipe and fluidly connected to the first pipe. The operating member is sleeved on the second pipe and axially movable relative to the second pipe between a first position and a second position, and rotatable around an axis of the second pipe.

Abstract: The present invention relates to an electronic atomizing device, an atomizer and a suction nozzle assembly thereof. The suction nozzle assembly includes a fixing base, a suction nozzle, and a connecting member. The suction nozzle includes a first end and a second end away from the first end. One end of the connecting member is mounted to the suction nozzle, another end is mounted to the fixing base, such that the suction nozzle is disposed on the fixing base via the first end, and is capable of rotating relative to the fixing base. The suction nozzle can rotate relative to a power supply assembly in the electronic atomizing device, therefore an operation switch of the power supply assembly can be rotated from an initial position to an operation position convenient for an operation.

Abstract: A vaporizer includes: a vaporization housing; and a first conductive structure and a second conductive structure that are electrically connected to a power supply assembly. The vaporization housing includes a hollow body and an insulating portion disposed on one end of the body, the insulating portion and the body being integrally formed. The first conductive structure and the second conductive structure are disposed in an insulating manner through the insulating portion. An air inlet is provided at a joint between the body and the insulating portion or the insulating portion.
