Abstract
An outlet device with hollow water curtain function includes a hollow housing and a deflecting column inserted in the housing. An annular passage is formed between the housing and the deflecting column. The housing further includes a plurality of arc-shaped inlet slots. The arc inlet slots are annularly arranged about the center of the annular passage. The internal port of the arc inlet slots is connected to the annular passage. Water flows to the annular passage through the arc inlet slots to from a hollow annular water curtain with centrifugal force. When the tangential centrifugal force of the water curtain orienting the opening angle of the housing is larger than the surface tension thereof, the water curtain breaks open to make the water flowing break open and diffuse as particles after keeping itself in a certain length. The diffused water forms a water type continuous in a certain range.
