Abstract
A water-saving antiblocking anti-splash waterfall water curtain head core comprises a housing having an upper portion internally enlarged and a flow leading mouth set inside the housing; a block is set under the flow leading mouth, and there are spaces between the upper surface of the block and the exit of the flow leading mouth; the upper surface of the block is fixedly connected with a support rod going through the flow leading mouth; a flow leading bracket with through holes is fixedly connected to the internally enlarged upper portion and to a top of the support rod; the flow leading mouth is such sized to anti-block. During operation, the surface of the block equally blocks water flow and accordingly forms hollow film-like water curtain.
