A spraying device includes a support arm mounted in a toilet bowl for pivoting between a retracted and an extended position at one of its ends, and carrying a spraying head at the other end. The spraying head has two compartments which are sealingly separated from one another, each of the compartments communicating with a different set of spraying apertures, one of the sets having a larger flow-through cross-sectional area than the other set. Separate conduits communicate a control valve to which a spraying liquid is delivered, with each of the compartments to issue through the two sets of apertures at different speeds in proportion to the different flow-through cross-sectional areas of the two sets. The control valve may be incorporated in the holder for the support arm, and the apertures of the two sets may aim in different directions, respectively. The compartment communicating with the set of larger total flow-through cross-sectional area may circumferentially surround the other compartment and its apertures may be inclined in the upward and frontward direction of the toilet bowl when the support arm is in its extended position in which the control valve is open.
A spraying device, particularly for use in toilets, comprising a spraying head including external wall means bounding a chamber and having at least one first and one second spraying aperture communicating said chamber with the exterior of said spraying head, and internal wall means subdividing said chamber into at least two compartments sealed with respect to one another and communicating with said first and said second spraying aperture, respectively;
