A plurality of air-releasing openings with inclined sidewalls are arranged at the periphery of the water tank of an aroma diffuser product, each air-release opening disposed in a position that is set at a certain angle along the inclined direction of the sidewalls. The certain angle being formed by the center longitudinal axis of the exit side of the opening relative to the radius of the water tank. A plurality of mist-releasing openings is arranged non-horizontally at the upper part of the water tank or the periphery of the water tank cover. An aroma diffuser or ultrasonic atomizer configured with the plurality of air-releasing openings and/or the plurality of mist-releasing openings.

Provided is a film forming apparatus capable of stably supplying a large amount of ceramic raw material powder for a long time and forming a homogeneous and dense film. A film forming apparatus 1 for forming a film on a base material K includes an aerosol transport path 10 for ejecting an aerosol obtained by dispersing a ceramic raw material powder in a gas, from an ejection end 10a toward the base material K, in which a flow path cross-section at an ejection end 10a of the aerosol transport path 10 has a substantially circular shape with an area of 10 mm.sup.2 or more.

Formulation and dispenser systems create dairy based toppings for beverages. The dispensers include a container, valve, and an actuator for the valve. The formulations include a liquid product and a propellant. The liquid product includes a certain percentage of milkfat provided, for example, by heavy cream, skim milk, nonfat dry milk, sweeteners, and an emulsifier. The propellant is nitrous oxide or nitrogen.

A vaporizer device may include a vaporizer body configured to couple with at least one vaporizer cartridge including a first reservoir and a second reservoir. The vaporizer device may include a first aerosol generation mechanism configured to generate a first part of an aerosol by at least vaporizing a first aerosol component present in a first vaporizable material in the first reservoir. The vaporizer device may also include a second aerosol generation mechanism configured to generate a second part of the aerosol by vaporizing a first aerosol component present in a second vaporizable material at a second temperature. The first part of the aerosol and the second part of the aerosol may be delivered, via a mouthpiece, to a user of the vaporizer device.

A process and apparatus for disinfection of spaces using a disinfecting liquid droplet spray atomization are described, in which an electric fan 107 is used to dispense the atomization from an atomization chamber 104 via venture outlets 106 into the space to be disinfected. The operation of the electric fan 107 is modulated in a cycle having a first phase in which the fan is operated at full speed and a second phase at which the fan is operated at a randomly selected speed to vary the rate of dispensing into the space in order to improve the dispersal of the atomized droplets in the space and hence the efficacy of disinfection.

An atomizing assembly includes a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is connectable to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured to deliver a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle includes an air channel configured to establish an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate.

A mobile hydrogen-oxygen burner rainmaking device includes a container, two liquid storage barrels, a combustion chamber and an igniter. The container has an accommodating space and a gas pipe. The liquid storage barrel is disposed in the accommodating space and connected to a nozzle and filled with liquid hydrogen and liquid oxygen separately. The combustion chamber is disposed in the accommodating space and has an opening. The igniter is installed in the combustion chamber. Each nozzle sprays the liquid hydrogen and liquid oxygen in a mist form into the combustion chamber for mixing, and the igniter ignites for combustion to form a high-temperature and high-pressure water vapor to be discharged from the opening along the gas pipe, so that the rainmaking device may be transported by a container truck to an appropriate location for operation to achieve the desirable rainmaking effect.

A compact diffuser integrates an atomizer and droplet separator into a surrounding sleeve, threadable to a bottle neck as an assembly. The assembly fits into a base, housing a motor and air pump, sealing the sleeve to a silo in the housing. Controls set time span of intermittent operation, intervening delay, and volumetric flow rate. The assembly pops into (and out of) the top end of a silo in the base, registering (aligning) circumferentially and axially to seal an air path from the pump to the atomizer. Access for applying force to the bottom of the assembly facilitates popping out the assembly when empty, or to simply change scent by changing out the assembly. Entire assemblies may be stored to simplify exchange and reduce chances for spills from reservoirs.

An aerosol-based printing apparatus is provided capable of producing an aerosol stream at a constant rate and constant material deposition to a substrate to provide high-definition, high-resolution traces. The aerosol-based printing apparatus provides production, transport, and delivery of an aerosol stream at a constant rate for a period of time of at least 8 hours and other instances more than 24 continuous hours of constant operation. By inhibiting bulging and necking of the deposited trace, superior line width tolerances are achieved, and such tolerances are maintained for extended periods of time, thereby allowing for both the deposition of complex traces as well as consistent manufacture of duplicate articles that maintain the tolerances across a production ran. The accumulation of fluids in the aerosol and gas transport conduits are eliminated, thereby eliminating the need for purge or cleaning cycles and allowing for uninterrupted operation for a minimum of 24 hours.
