Claim:
1. A spray structure of a water spray gun, formed on a surface cover, the surface cover being formed with a plurality of spray orifices, an inner side of the surface cover being formed with annular flanges each corresponding to an edge of each spray orifice, each annular flange being formed with a tangential opening defining a water passage extending in a direction tangential to an inner circumference of an inner wall of the annular flange, wherein the surface cover comprises two circumferentially extending walls that are spaced from each other in a radial direction to define therebetween a circumferential water flow channel that has a bottom above which a space is delimited between the two walls for water to flow therethrough, the plurality of spray orifices being formed in the bottom of the flow channel, the annular flanges being raised from the bottom of the flow channel and extending into the space, such that water is guided to flow in the space circumferentially along the flow channel, in a manner of being substantially parallel to the bottom of the flow channel, to reach and pass through the water passage formed in each of the annular flanges toward the spray orifice corresponding thereto.
