Abstract: 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.

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.
