Description

FIELD OF THE INVENTION

The present invention relates to an electronic cigarette device, and in particular, to an electronic cigarette atomizing core and an atomizer.

BACKGROUND OF THE INVENTION

The first electrode of the ultrasonic atomizing sheet of the existing ultrasonic electronic cigarette atomizer is generally connected to an electrode assembly by a wire, so the atomizing core is inconvenient to assemble, and solder joints at two ends of the wire easily fall off, resulting in poor conductivity of the ultrasonic atomizing sheet. In addition, during ultrasonic atomization, because the supply speed of e-liquid is slow, the ultrasonic atomizing sheet is easily dry-burnt. Further, because the air pipe is directly communicated with the atomization cavity, the e-liquid splashed on the ultrasonic atomizing sheet enters the vent tube connected with the suction nozzle during the atomization. Hence, the user easily inhales the e-liquid.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, and provide an electronic cigarette atomizing core which is convenient to assemble, does not require welding wires and can also protect the ultrasonic atomizing sheet, and an atomizer.

During smoking, the e-liquid tank continuously supplies e-liquid, and a part of intake air flow in the atomization cavity is continuously filled into the e-liquid tank to increase the air pressure of the e-liquid tank, thereby increasing the supply speed of e-liquid and effectively preventing dry burning of the ultrasonic atomizing sheet.
Preferably, an inner cavity of the inner sleeve is provided with a boss, for sealing and clamping a vent tube, and an air outlet cavity sequentially from top down, so that the e-liquid splashed during ultrasonic atomization is condensed on the inner wall of the air outlet cavity, and the user hardly inhales the e-liquid.
