A hand held shower head configured to deliver a continuous dose of water dispersed treatment from a water disintegratable treatment source, the shower head including: a hollow body having water inlet opening and water outlet, the water outlet defined by a perforated plate, and a mesh formation disposed within the hollow body between the water inlet opening and the perforated plate, wherein the water inlet opening, hollow body and perforated plate are configured to create in use a pressurised turbulent water flow within the hollow body prior to exiting through the perforated plate, whereby a water disintegratable tablet treatment source introduced into the hollow body prior to use, is then agitated by the turbulent water flow against the mesh in an abrading manner and thereby dispersed into the water flow exiting the perforated plate. A water disintegratable tablet comprising emulsifier, thickening agent, surfactants, oil and rheology modifier is also disclosed.

A fluid cleaning device includes a spheroid-shaped member defining an internal void. The spheroid-shaped member further includes a wall defining a plurality of apertures and at least partially surrounding the internal void and an inlet orifice that receives a cleaning fluid under pressure. A tubular nozzle projects from the inlet orifice and into the internal void to mitigate fluctuation of one of the internal pressure and flow velocity of the cleaning fluid within the spheroid-shaped member.

A flow divider for diverging a fluid includes a main body that includes first and second side surfaces being opposite to each other along a central axis of the main body. The first side surface has a central segment transversely intersecting the central axis, and having an inlet channel recessed toward the second side surface, a generally annular channel surrounding the central segment, recessed toward the second side surface, and spatially communicated with the inlet channel at a junction space, and an inclined segment surrounding the annular channel. A width of the annular channel decreases gradually from a start measurement to an end measurement along a rotational direction with respect to the central axis.

A concentrator nozzle attachment for a blower device is disclosed that increases the airflow velocity of the blower without sacrificing the field of the jetting air. The concentrator nozzle is formed of an outer ring with a centrally located guide surface and is placed at the exit of an air tube. As the air exits the air tube, it's forced to flow around the guide surface, thus increasing its velocity. The attachment is secured to the end of the air tube and so does not alter the outer diameter through which the air exits. In this way, air velocity is increased without reducing its effectiveness.

A step cavity type low frequency ultrasonic atomization nozzle with a swirlable vortex impeller, has an air intake casing, an inlet casing, a Laval core, a fixed cap, an adjustable pedestal, and taper rectifying sleeve, swirlable vortex impeller, stepped resonance tube, regulative plunger, positioning lead, second pedestal. The regulative plunger is located in the second stepped hole of the stepped resonance tube, and its axial position is adjustable; the swirlable vortex impeller is fixed on the taper resonance tube through the bearing, and the outer cone surface is matched with the inner cone surface of the taper rectifying sleeve. The resonant cavity is improved so that the two-phase fluid in the cavity can generate higher frequency and greater fluctuation of the pressure fluctuation amplitude, optimize the initial atomization performance of the nozzle, and optimize the nozzle outlet, and increase the swirlable vortex impeller.

A variable-flow-rate anti-clogging emitter includes an upper casing and a lower casing, where the upper casing and the lower casing are fixedly connected with each other; the upper casing has a flat top surface provided with a water outlet and a bottom surface provided with a truncated conical slot in communication with the water outlet; the lower casing includes a flow channel portion and a discharging portion, which are recessed in an upper surface of the lower casing; the flow channel portion has one end provided with multiple parallel feeding channels and an other end communicated with the discharging portion; one end of a lower surface of the lower casing is provided with an L-shaped platform; water inlets of the multiple feeding channels are arranged on a side wall of the L-shaped platform; and an elastomer flow channel is fixedly provided between the upper casing and the lower casing.
