Abstract: A spray arrangement, particularly a brush-like body-cleaning and/or massage device, particularly a toothbrush (1) with at least a nozzle body (10') may be coupled to a hollow handle which is connectable by a hose to a water faucet. Nozzle body (10') is preferably a fluidic oscillator without moving parts. The hollow handle may receive into a metering cartridge a rod of a slow-to-dissolve active substance. The handle is provided with a removable elongated cap whose forward end may be coupled securely irrotationally with tube (5) of the cleaning brush. Moreover, the cap includes a manually actuatable water valve which is manually displaceable into the open position against a spring force and/or opposing water pressure. The water valve is preferably formed as a multi-step slide valve piston (68) with a conical shut-off member (72).

Abstract: A hollow handle (1), which is connected at one end to a water hose (2), and which is connectable at the other end to a fluidic cleaning and/or massaging device, especially a mouth cleansing shower, a face cleaning brush or a denture cleaning device, comprises a dosing space (40) or takes up a separate dosing container (9, 25, 29). An effective substance is located in the dosing space or in the insertable dosing container. The dosing space or the dosing container is provided with a device (11, 27, 35, 36, 42) for dispensing a small, especially an adjustable quantity of the effective substance into the water stream guided through the hollow handle. The effective substance may be solid or liquid. Solid effective substances which are hard to dissolve are preferably shaped as rods which are insertable into a respectively adapted elongated dosing container (9), which is provided with a certain number of holes (14, 14') corresponding to the quantity of the effective substance selected to be dissolved.
