The return pipe 31 has a diameter larger than the diameters of the first metering pipe 33 and the compression pipe 29, and the first metering pipe 33 has a diameter larger than the diameter of the compression pipe 29. The water supplied through the first water adjusting pipe 33 flows into the return pipe 31, and since the diameter of the return pipe 31 is larger than the diameters of the first water adjusting pipe 33 and the compression pipe 29, the water cannot flow from the compression pipe 29 to the water spray pipe 7 at once, and the water flows are collided with each other in the return pipe 31. Such a design may improve the atomization effect at the atomizer 6. Meanwhile, the diameter of the compression pipe 29 is smaller than that of the return pipe 31, so that the flow speed of the water flow sprayed out through the compression pipe 29 is faster, and the range of the direct-flow atomization water gun 1 is increased.
