An essential oil reflux-type atomizer comprising the following structures: a chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. Oil and gas flow together at the gas and oil nozzles to disperse and atomize the oil in the gas flow. A heater is used to raise the temperature of the oil where it is atomized, either by heating the oil itself or by heating the gas flowing into the oil. Thus, the atomizer can have improved performance, especially with essential oils having high viscosity and molecular weight.

A liquid membrane 100 is formed by jetting a liquid sucked from a recovery reservoir 11a and pressurized using a pump 12 from a nozzle of a liquid membrane cartridge 20. The formed liquid membrane 100 makes contact with a slope wall of the liquid membrane cartridge 20 along a surface of the liquid membrane 100. The liquid running down from the slope wall is recovered and stored in the recovery reservoir 11a in order to recover the liquid running down along the slope wall in a decelerated state into the recovery reservoir 11a. As a result, it is possible to prevent air bubbles from being generated by agitation of a liquid of the recovery reservoir 11a when the liquid enters the recovery reservoir 11a.

It is prevented that residual fuel left in the vicinity of an injection nozzle outlet is carbonized to cause adherence of the carbonized fuel as deposit and changing of a spray pattern or an injection flow rate. A fuel injection valve includes a seat portion on which a valve body is seated and a seat portion in which an injection hole for injecting fuel downstream from the seat portion is formed, in which a concave surface denting in a direction opposite to a fuel injecting direction is formed on an outer peripheral side away from the injection hole at an end face located downstream of the seat member, and the concave surface is formed such that a material surface in an outer peripheral region has a larger wettability for the fuel than in an inner peripheral region.

An ablutionary fitting includes an outlet for providing a stream of water and a dispersing barrier arranged in the stream, such that the liquid passing through the dispersing barrier is broken up into a plurality of smaller streams, forming a spray, wherein the smaller streams are at least in part directed by the dispersing barrier.

A method of denuding bone stock with a denuder, such as a bone stock denuder container, is disclosed. The bone stock is deposited into a wash chamber formed with a curved chamber wall. The bone stock is impacted with a stream of fluid under pressure to separate non-bone tissue from bone. Fluid and non-bone tissue are drained from the wash chamber.

A showerhead assembly for dispersing liquid is disclosed herein, comprising a back part; a front part coupled to the back part to form a plurality of dispersion chambers; an inlet boss disposed between the front part and back part for connecting a liquid supply line; a liquid supply rail disposed between the front part and the back part and connected to the inlet boss for leading liquid to the dispersion chambers; and a plurality of support members slidably coupled to the front part such that the support members can slide between the front part and the back part.

A hygienic spray deflector apparatus includes an inlet opening, an outlet opening, and at least one wall that encloses a space between the inlet opening and the outlet opening. The hygienic spray deflector further includes a spray deflector in the space between the inlet opening and the outlet opening. The spray deflector is configured to deflect fluid that enters the hygienic spray deflector through the inlet opening. The hygienic spray deflector further includes a connector between the spray deflector and the at least one wall. The connector is configured to fix the spray deflector in place within the space. The connector is configured to allow air flow between the inlet opening and the outlet opening.

An atomizer for applying a coating includes a nozzle plate, an actuator, and an acoustic focusing device. The nozzle plate defines at least one aperture. The actuator is configured to oscillate to form pressure waves within a fluid to eject the fluid from the nozzle plate. The acoustic focusing device focuses the pressure waves toward the apertures.

A spray diffuser for a pool cleaner is coupled to the end of the tail sweep hose which expels pressurized water out of the end of the hose. The diffuser includes a flow shaping nozzle configured to form a diverging pressurized water stream. The shaping nozzle can be attached directly to the end of the hose with a flow obstruction of the shaping nozzle immediately adjacent the flow discharge. A dissipating portion dissipates the pressurized water stream when the spray diffuser is positioned above the surface of the water to prevent water spraying out of the pool.
