As shown in fig. 1 and 2, an atomizing nozzle 10 includes a nozzle base 1 having a first passage 1a for receiving a fluid. The atomizing nozzle 10 further includes a first stopper 2 having a second passage 2a and a first guide cone 2b surrounding the second passage 2 a. The atomizing nozzle 10 further includes a first rib 12 having one end connected to the nozzle base 1 and the other end connected to the first stopper 2, a second stopper 3 having a second flow guiding tapered surface 3b, and a second rib 23 having one end connected to the first stopper 2 and the other end connected to the second stopper 3. After the fluid flows out of the first channel 1a of the nozzle base body 1, the first stop block 2 can receive one part of the fluid through the second channel 2a and guide the fluid to flow out, and can receive the other part of the fluid through the first flow guiding conical surface 2b and cause the fluid to directly impact the first flow guiding conical surface 2b and splash to the periphery of the first stop block 2; after the fluid flows out of the second channel 2a of the first block 2, the second block 3 can receive all or part of the fluid from the second channel 2a through the second flow guiding conical surface 3b and make the fluid directly impact the second flow guiding conical surface 3b and splash to the periphery of the second block 3.
