Methods and devices for atomizing a fragrant liquid can use a reservoir that receives a volume of a base liquid. One or more drops of a substance are added to the base liquid to form a volume of an aromatic liquid. A vaporizer atomizes the aromatic liquid, forming a mist that is emitted from the device. The device allows a user to customize the blend of substances that are used to form the aromatic liquid.

A humidifier, for a ventilation system, that includes an atomizer configured to deliver water droplets into a flow of breathing gases and a heating element configured to vaporize the water droplets emitted from the atomizer. The humidifier may be configured to set a target inhalation gas temperature based on internal temperature of a patient. Further, based on inspiratory flow and humidity data about breathing gases upstream of the atomizer of the humidifier, the humidifier may calculate and deliver an amount of water in one or more bursts of atomized water. Based on the target inhalation gas temperature, the humidifier may control a temperature of the heating element.

The invention relates to a device for producing special effect fog, in particular in the field of stage technology, comprising fog generator (1) which is equipped with a heating element, wherein a fog fluid is evaporated by means of the heating element, and at least one ultrasonic vaporizer (5) which is arranged in a housing (2) on the bottom (3) of a main mixing chamber (4), wherein the fog which is generated by the fog generator (1) can be conducted into the main mixing chamber (4), and wherein, furthermore, a baffle wall (7) is provided in the main mixing chamber (4) close to an outlet opening (6). In addition, a pre-mixing chamber (8) is provided, into which an air stream which is generated by a fan (9) and the fog which is generated by the fog generator (1) can be introduced via respective access openings (14, 15). The pre-mixing chamber (8) is connected by means of a transfer opening (10) to the main mixing chamber (4), wherein the transfer opening (10) is arranged in the main mixing chamber (4) so as to lie opposite the baffle wall (7).

An apparatus, system, and method for providing a non-linear fluid stream into an environment for cooling purposes are disclosed. Such an apparatus includes a body portion and a nozzle, the nozzle being adapted to direct water into the environment. Such an apparatus may include a body portion having a flow channel defined therein for gas flow therethrough; and, a nozzle operatively disposed within the flow channel; said nozzle adapted to direct a liquid therefrom; wherein the channel and the nozzle are operatively disposed relative to each other so that a gas flowing through the channel and the liquid are combined into a fluid stream directed from the apparatus into the surrounding environment.

A spray device comprises a diaphragm pump, a spray gun and a hose. The diaphragm pump comprises an air outlet to supply air flow, a casing and a pump assembly disposed in the casing. The spray gun comprises a housing and a Venturi tube arranged entirely inside the housing. The housing has an air inlet to receive the air flow supplied from the diaphragm pump and guide the air flow into the Venturi tube. The spray gun comprises a paint receptacle that receives and holds therein a paint material that is supplied into the spray gun and atomized to form paint droplets and entrain the air flow received from the diaphragm pump to allow the paint droplets to be sprayed onto a workpiece. The hose has two ends respectively coupled to the air outlet of the diaphragm pump and the air inlet of the spray gun.

An accurately mixed fragrance can be provided. A fragrance generation device includes: a first ultrasonic vibrator provided in a water container that contains water and used for atomizing the water; a first emission hole used for emitting the water atomized by the first ultrasonic vibrator; a plurality of second ultrasonic vibrators provided in a plurality of perfume containers that individually contain multiple types of perfumes, respectively, and used for atomizing the perfumes; a plurality of second emission holes arranged around the first emission hole and used for emitting the perfumes atomized by the plurality of second ultrasonic vibrators; and a control unit configured to control driving of the first ultrasonic vibrator and the second ultrasonic vibrators.

A necklace misting fan includes a housing, a water reservoir, spray pump system, power supply, fan, and motor within the housing, an air inlet on a front side of the housing, and an air outlet on a top side of the housing. A fan power switch and a spray pump actuator are mounted to the housing. A spray nozzle on the top side of the housing horizontally spaced from the air outlet, is adapted and configured to emit a water spray generally vertically upward and obliquely to a generally vertical upward discharge air stream from the air outlet, when the spray pump actuator is actuated.

A spray gun includes a gun body having a front body portion and a spray cap assembly attached to the front body portion of the gun body. The spray cap assembly includes a nozzle assembly and a spray cap positioned over the nozzle assembly. The nozzle assembly includes a nozzle piece configured to attach to the front body portion of the gun body and an air flow guide surrounding the nozzle piece. The spray cap interfaces with the air flow guide. The air flow guide is configured to engage with the nozzle piece so that the air flow guide is prevented from moving past the nozzle piece.

A method and an apparatus for the delivering of liquid mixtures of phytosanitary products is disclosed, equipped with a pneumatic liquid mixture atomization system which includes a fan for generating a carrier airflow through at least one diffuser with a conduit tapering towards a reduced section, and at least one delivery nozzle of the liquid mixture within the diffuser.
