A medical fluid suspension generating apparatus for performing medical procedures includes a Venturi-agitating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed medical fluid unit fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly. Pressurized gas, from the compressed medical fluid unit, and the medical solution are combined within the Venturi-agitating tip assembly in a manner generating an enriched medical suspension that is ultimately dispensed from the suspension delivery apparatus.

A bubble generating device is disclosed which includes: a bubble generator including a tubular body, a liquid introduction port, a gas introduction port, and a discharge port; and a gas supply unit including a gas supply port, a pressurized gas being supplied to the bubble generator through the gas supply port, wherein the flow passage of the bubble generator extends substantially along a same axis, a plurality of reduced diameter portions each having an inner diameter reduced are provided along a direction along which the liquid flows, and gas-liquid mixing portions are provided downstream of the respective reduced diameter portions in a contiguous manner, each of the gas-liquid mixing portions having an inner diameter larger than a minimum inner diameter of each of the plurality of reduced diameter portions, and the gas introduction port of the bubble generator is formed of a plurality of through holes.

An aromatherapy nebulizer and an aroma diffuser of the same are proposed in the present invention. The aroma diffuser includes the aromatherapy nebulizer and a main body to mount the aromatherapy nebulizer. The aromatherapy nebulizer includes an atomizer; and an essential oil container. The atomizer includes an atomizing seat defined an atomization chamber therein and an outer cover defining a mist outlet. The atomizing seat is provided with an air conduit and a liquid conduit; the liquid conduit defines an essential oil channel therethrough. The essential oil channel is bent at one end of the liquid conduit which forms a liquid outlet, thereby the essential oil is absorbed upwards to the liquid conduct from the essential oil container and changes a direction sprayed out from the liquid outlet.

A mister apparatus includes a portable mister body having an air inlet and an air outlet, a fan configured to draw air in through the air inlet and force the air out the air outlet, a reservoir configured to contain a liquid, the reservoir having a reservoir outlet, a liquid outlet, the liquid outlet being disposed adjacent to or downstream of the air outlet, and a pump in fluid communication with the reservoir. The pump is operable to move the liquid from the reservoir and out of the liquid outlet such that the liquid exiting the liquid outlet enters into the air exiting the air outlet to form a mist.

An essential oil reflux-type atomizer comprising the following structures: chassis (10), housing (30), atomization chamber (310), gas pump (21), gas tube (22), gas nozzle (23), oil nozzle (24), filter atomization mechanism (40). The filter atomization mechanism (40) is installed in the housing (30) and has a plurality of filter housings (41). A lower end of each of the filter housings (40) has one or more through holes (411). When the gas nozzle (23) ejects an airflow, the airflow draws out the essential oil through the oil nozzle (24) to form a mixed airflow which passes through each of the filter housings (41) successively. Larger essential oil droplets in the airflow are filtered by each of the filter housings (41) to be recycled, while the atomized essential oil gas will pass through the through holes (411) of each of the filter housings to be dispensed. At the same time, the essential oil droplets in the through holes (411) are re-atomized by the airflow to improve the atomization performance. The atomization chamber (310) comprises a guide board guiding the airflow from the gas nozzle (23) upwards towards the filter atomization mechanism (40).

A conical-jet spray nozzle (1) comprises a body (2), of generally axisymmetric shape, with an inlet zone (11) for liquid and an outlet (12), and a core (3), at least partially housed in the body (2). The core (3) is arranged so as to mix the liquid passing through it with air, upstream from the outlet (12). The nozzle (1) further comprising an additional part (5), disposed downstream from the inlet face (11) and upstream from the core (3). This additional part (5) is arranged so as to gyrate a liquid jet about the axis (XX′) of the body (2).

A vaporization device is provided with a control valve on a flow path along which flows a liquid material, a vaporizing portion in which the liquid material is vaporized by decompression or heating, a liquid flow rate sensor that measures a flow rate of a liquid material flowing along the flow path, and a valve controller that controls the control valve using PI control or PID control that is based on a set value showing a set flow rate and on a measurement value of the flow rate that is measured by the liquid flow rate sensor. The vaporization device is configured to, during a transient response period of the flow rate that is measured by the liquid flow rate sensor, switch the integral gain set in the valve controller from a reference integral gain to a corrected integral gain that is different from the reference integral gain.

A dispenser system for applying multi-component adhesives or like substances to work surfaces in carpeting, roofing and like applications as well as a method of dispensing and applying multi-component adhesives to work surfaces.

A foam dispenser having a metal housing has a spool valve socket therein. A metal handle extends from the housing. A spool valve is disposable within the spool valve socket. A trigger couplable to the spool valve enables the spool valve to be rotated between open and closed orientations within the housing. The spool valve has internal channels for selectively passing liquids through the spool valve in the open orientation and not in the closed orientation. The spool valve also has a channel for selectively passing a gas through the spool valve in both the open and closed orientations.
