Abstract: A showerhead engine internally swirls water within a swirling chamber. Multiple swirling chambers may be used, each separated from one another. The water is swirled angled through holes in a mid plate. As the water passes through the angled holes, it is projected out an angle. The water then contacts the swirling chamber wall and continues to follow the curvature of the wall. The curved wall paired with the angled entry causes the water to continue to swirl within the swirling chamber. The water is released out of the swirling chamber through slots, which allow the water to retain the angular velocity at a discharge angle.

Abstract: The invention is an apparatus unit that adjusts the dispersion from a compartment to an aqueous solution in response to an independent variable such as an environmental factor, in order to optimize seeding, marking, warning or treatment. The compartment enables any selection of solids, liquids or gasses to be contained and mixed when ready for dispersion. A preferred embodiment is a solar powered pump, self-contained within a buoy over a shallow tidal pool, for the purpose of distributing seeds for marine vegetation under ideal conditions for propagation. The unit provides for sensing and measurement of the environment, then adapting the dispersion for optimum effect.

Abstract: A showerhead assembly is provided which includes a conduit, a gear train and oscillating nozzle chamber. The gear train includes a propeller, toothed pinion, and large toothed gear. Water flows from the conduit into an internal chamber within the showerhead housing. Specifically, water enters the propeller thereby causing it to rotate, the rotation of which causes the pinion to rotate, and consequently, the large gear to revolve. Additionally, a pin seated on the large gear engages with the pin slot located on the nozzle chamber and causes the chamber to pivot, thereby restricting chamber movement as the pin oscillates with rotation of the large gear. Further, the chamber's horizontal movement is hindered by two shoulder arms. As water exits the large gear, it travels through the left shoulder arm's central channel and into the oscillating chamber, whereby it expels through the nozzle outlet in a reciprocating spray pattern.

Abstract: Disclosed is a needle-type vibrate-to-nebulize apparatus and nebulizer for nebulizing fluids, in particular essential oils. The needle-type vibrate-to-nebulize apparatus mainly comprises the air passage designed in the module, the steel needle and the vibrating unit. Fluid is delivered from the rear end to the front end, then nebulized at the front end by high-frequency vibration. The nebulized mist is blown out through the air passage. The nebulizer mainly comprises the needle-type vibrate-to-nebulize apparatus and the peristaltic pump with rollers. The peristaltic pump with rollers is capable of sucking and supplying essential oil to the steel needle, as well as reversing the oil back when power off to prevent clogging. High-frequency vibrating action of the vibrating unit is generated by the piezoelectric disk and induced to the steel needle. As a result of resonation, essential oil is nebulized at the front end and blown out through the air passage.
