An outdoor misting assembly for producing a cooling mist during hot day includes a housing that has a fluid reservoir therein that can be filled with water. A misting unit is positioned in the fluid reservoir and the misting unit can be submerged in the water. The misting unit vibrates at a pre-determined frequency when the misting unit is turned on to vibrate the water into a mist. A plurality of tubes is each fluidly coupled to the misting unit to receive the mist. Each of the tubes extends outwardly from the housing to direct the mist toward a plurality of users for cooling the users during a hot day.

An air-assisted electrostatic ultrasonic atomization nozzle includes an intake sleeve, a Laval tube, a resonant body and a jet element body. The left end of the intake sleeve is equipped with the air intake, and the right end of the air inlet sleeve is connected with the left end of the Laval tube. The right end of the Laval tube is connected with the left end of the resonant body. The right end of the resonant body is connected with the left end of the jet element body. The sealing surface of the resonant tube is arranged between the resonant body and the jet element body. The sealing surface of the resonant tube obstructs the gas-liquid in the axial direction of the resonant body and the jet element body. The resonant body has a resonant chamber, and the sidewall of the resonant body is equipped with a V-shaped resonant tube.

A variable-frequency surface acoustic wave electronic cigarette includes an atomizer. An atomization cavity is disposed in the atomizer, and a variable-frequency surface acoustic wave atomization chip is disposed at a lower portion of the atomization cavity. An inverted trapezoidal interdigital transducer is disposed on the variable-frequency surface acoustic wave atomization chip. An e-liquid storage cavity is disposed in the atomization cavity. A porous ceramic sheet is disposed between the e-liquid storage cavity and the atomization chip. The new variable-frequency surface acoustic wave electronic cigarette can realize any adjustment of the working frequency within a set range, thereby realizing the autonomous regulation and control of a smoke particle size after atomization of the e-liquid.

An artificial flame apparatus produces a simulated flame using a plume of mist that is illuminated around, about, and/or through an artificial wick. A mist may be produced by a transducer, such as an ultrasonic transducer, that is in contact with liquid from a liquid reservoir. The rate of mist exiting the housing may be modulated to produce a more realistic looking artificial flame. An airflow device may control, shape, vary, and/or move the mist in the creation of the vapor plume. Airflow channels, inlet and outlet ports, openings (angled and/or straight) to effectively transport air to control movement and/or shape plume characteristics (e.g. height, width, density, shape) to simulate the look and effect of a realistic dancing flame. A light source is configured to illuminate the mist and/or the artificial wick.

A liquid sample introduction system for a plasma spectrometer includes a sample container for holding a liquid sample, a surface acoustic wave (SAW) nebulizer, arranged to receive a liquid sample from the sample container, an electronic controller for supplying electrical power to the SAW nebulizer so as to produce a surface acoustic wave on a surface of the SAW nebulizer, for generating an aerosol from the supplied sample liquid, and an aerosol transport arrangement for receiving the aerosol from the SAW nebulizer and carrying it into a plasma or flame of a spectrometer. The electronic controller is further configured to control the electrical power to the SAW nebulizer so as to permit adjustment of the aerosol parameters, and to control the aerosol transport arrangement so as to permit adjustment of the aerosol delivery into the plasma or flame of the spectrometer.

An ultrasonic atomization core (17), an ultrasonic atomizer, and an ultrasonic electronic cigarette are disclosed. The ultrasonic atomization core (17) comprises an atomization sleeve (1). The atomization sleeve is provided with an ultrasonic atomization sheet (2) and e-liquid guide cotton (3) that communicates the outside with an atomization surface of the ultrasonic atomization sheet (2).
