An ultrasonic electronic cigarette atomizer and an electronic cigarette are disclosed. The atomizer includes a housing, a nozzle assembly that is connected to one end of the housing, an air inlet channel, an air outlet channel, and an ultrasonic atomization sheet that is disposed in the housing. The air inlet channel, an atomization region of the ultrasonic atomization sheet, and the air outlet channel are sequentially communicated. An outlet of the air inlet channel is opposite to the atomization region of the ultrasonic atomization sheet. The nozzle assembly comprises a nozzle holder mounted to one end of the housing, and a suction portion on the nozzle holder communicated with the air outlet channel.

A volatile material dispenser includes a base that houses a printed circuit board. The volatile material dispenser also includes a stand assembly and a shroud. The stand assembly is coupled with the base. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The manifold contains a circular piezoelectric element. The shroud is positioned on the base. The shroud defines a chimney that is centered along a longitudinal axis. The manifold includes an annular wall that extends from the manifold. A spring is disposed within the manifold and is coaxial with the annular wall. A top end of the spring is wrapped around the annular wall and a bottom end of the spring applies a force against the piezoelectric element.

A method for removing bodily fluid includes drawing bodily fluid that has accumulated in excess, converting the drawn fluid from bulk liquid form to aerosol form, and disposing of the aerosol via evaporation of liquid droplets and absorption and/or diffusion of vapor. Conversion from bulk liquid to aerosol may include collecting the bulk liquid fluid in a reservoir, conveying the bulk liquid bodily fluid to an atomizer, converting the bulk liquid fluid into an aerosol having ultrafine droplets, and ejecting the aerosol into a subcutaneous space for disposal via evaporation of liquid droplets and absorption and/or diffusion of vapors. The method may be performed with a subcutaneous atomizer that may be controlled locally or by an external transmitter for effecting a conversion and mist rate to keep pace with the accumulation of excess bodily fluid.

Disclosed is an electronic cigarette atomizer including a liquid cartridge (6) and an ultrasonic atomization piece (42) mounted vertically. The liquid cartridge (6) is located above the ultrasonic atomization piece (42), a liquid guide channel (311) communicated with the liquid cartridge (6) is disposed below the liquid cartridge (6), a liquid outlet (331) is horizontally disposed in the liquid guide channel (311), and the caliber of the liquid outlet (331) is smaller than that of the liquid guide channel (311); and liquid guide cotton (43) is horizontally mounted across the ultrasonic atomization piece (42). The liquid guide cotton (43) is in contact with or attached to an atomization surface of the ultrasonic atomization piece (42), and the liquid outlet (331) abuts against the liquid guide cotton (43). With the electronic cigarette atomizer, when smoking, e-liquid is supplied in time, and e-liquid supply and ultrasonic atomization are balanced, such that the burning phenomenon can be prevented. When not smoking, the liquid outlets are blocked by means of the viscosity of the e-liquid itself and the liquid guide cotton (43), such that the e-liquid is prevented from being continuously conducted by the liquid guide cotton (43), and the situation where an atomization cavity is soaked in the e-liquid and liquid leakage is consequently caused is avoided.

An electronic cigarette atomizing core (4) and an atomizer are disclosed. The electronic cigarette atomizing core (4) includes an outer sleeve (42) and an inner sleeve (43), wherein the outer sleeve (42) is provided with a liquid passing port (421). An ultrasonic atomization piece (46) is arranged in an inner cavity of the outer sleeve (42); and an atomization cavity (41) is provided between the bottom of the inner sleeve (43) and the ultrasonic atomization piece (46). A liquid guide cotton (45) in communication with the liquid passing port (421) is sandwiched between the outer sleeve (42) and the inner sleeve (43). The inner sleeve (43) is longitudinally provided with a main air groove (431) and an auxiliary air groove (4321) at intervals. The cross sectional area of the auxiliary air groove (4321) is ¼ to ⅛ the size of the cross sectional area of the main air groove (431). The main air groove (431) is in communication with the atomization cavity (41) to form a first air inlet channel. An auxiliary air inlet (436), an auxiliary air channel (437), the auxiliary air groove (4321), and the atomization cavity (41) are in communication with each other to form a second air inlet channel.

An atomizer for an electronic cigarette is provided. The atomizer comprises a liquid cartridge device with a liquid outlet, atomization cotton, and an ultrasonic atomization piece. The middle of the atomization cotton abuts against a central area of the ultrasonic atomization piece by means of a spring to form an atomization zone. An end portion of the atomization cotton is pressed against the bottom of the liquid cartridge device and covers the liquid outlet. An atomization cavity is provided between the ultrasonic atomization piece and the bottom of the liquid cartridge device. An atomization cavity gas inlet and an atomization cavity gas outlet are provided at the top of the atomization cavity. The atomization cavity gas inlet (501) and the liquid outlet (321) are staggered.

A volatile material dispenser includes a base that houses a printed circuit board, a stand assembly that is coupled with the base, the stand assembly including a platform, a stand that extends from the platform, and a manifold that extends from the stand, the manifold containing a circular piezoelectric element. The dispenser further includes a shroud that is coupled with the stand assembly and defines a chimney, and a refill comprising a wick, the refill being removably coupled with the manifold. The manifold includes a cylindrical wall that extends upward from the manifold, a spring is disposed within the manifold and is coaxial with the cylindrical wall, and a top end of the spring is wrapped around the cylindrical wall and a bottom end of the spring applies a force against the piezoelectric element.
