The invention relates to a flexible spraying nozzle capable of realizing two-stage swirl mixing. The flexible spraying nozzle capable of realizing two-stage swirl mixing comprises an oil pipe, a conevalve, an air pipe, a casing, a first-stage swirl mixing pipe and a second-stage swirl mixing pipe, wherein a low-pressure oil return hole is formed in the top of the oil pipe; the cone valve is arranged in the oil pipe, a boss is formed on the side wall of the cone valve, an oil return channel is formed in the cone valve and communicates with the low-pressure oil return hole of the oil pipe, thebottom of the oil pipe is connected with the top of the first-stage swirl mixing pipe, and a first sealing ring is arranged at the joint; the bottom of the first-stage swirl mixing pipe is fixedly connected with the top of the second-stage swirl mixing pipe, a swirl mixing cavity is formed in the joint of the first-stage swirl mixing pipe and the second-stage swirl mixing pipe which are both arranged in the casing, the bottom of the second-stage swirl mixing pipe is connected with the bottom of the casing, and the top of the casing is in threaded connection with the air pipe and communicates with the air pipe; the oil pipe is sleeved with the air pipe and the air pipe is fixedly connected with the outer wall of the oil pipe. The whole structure is reasonable in design, the problem of manual regulation is solved, the function of regulating flow flexibly to meet requirements of power is realized, the atomizing effect is improved, and the practicability is high.
