The present invention proposes a handheld spray fan.

In the embodiment of the present invention, as shown in, the handheld spray fan includes a housing assembly, a fan assembly, and a spray device. The housing assemblyhas a handheld part, an air duct at one end of the handheld part, and an air outlet coverat the end of the air duct. The air outlet coverhas a through-holeand multiple air outlet holessurrounding the through-hole. The fan assemblyis installed within the air duct. The spray deviceincludes a water tank, a water pipe, a mounting seat, a fiber water guide, and an atomizer. The water tankis positioned within the housing assembly. The water pipeconnects the water tankand the mounting seat. The mounting seatis located at the through-hole. The atomizer is installed on the mounting seatand exposed through the through-hole. The fiber water guide is installed within the water pipe. The fiber water guide extends from the water tankto the atomizer.

Specifically, during use, the fan assembly blows air, while water from the water tankis transported through the fiber water guide in the water pipeto the mounting seat, and the atomizer atomizes the water in the mounting seat, spraying it out through the through-hole. The through-holeis positioned in the middle of multiple air outlet holes, placing the spray in the middle of the airflow generated by the fan assembly. This prevents the spray from dispersing and ensures stable water transport to the atomizer, avoiding interruptions in the spray.

The technical solution of the present invention, by setting up a housing assembly, a fan assembly, and a spray device, where the housing assemblyhas a handheld part and an air duct at one end of the handheld part, the fan assemblyis installed in the air duct, and the air outlet coveris installed at one end of the air duct, having a through-holeand multiple air outlet holessurrounding the through-hole.
