The present invention proposes a handheld spray fan.

In the embodiment of the present invention, as shown in FIGS. 1 to 7, the handheld spray fan includes a housing assembly 10, a fan assembly 20, and a spray device 30. The housing assembly 10 has a handheld part, an air duct at one end of the handheld part, and an air outlet cover 12 at the end of the air duct. The air outlet cover 12 has a through-hole 121 and multiple air outlet holes 122 surrounding the through-hole 121. The fan assembly 20 is installed within the air duct. The spray device 30 includes a water tank 31, a water pipe 32, a mounting seat 33, a fiber water guide, and an atomizer. The water tank 31 is positioned within the housing assembly 10. The water pipe 32 connects the water tank 31 and the mounting seat 33. The mounting seat 33 is located at the through-hole 121. The atomizer is installed on the mounting seat 33 and exposed through the through-hole 121. The fiber water guide is installed within the water pipe 32. The fiber water guide extends from the water tank 31 to the atomizer.

Specifically, during use, the fan assembly blows air, while water from the water tank 31 is transported through the fiber water guide in the water pipe 32 to the mounting seat 33, and the atomizer atomizes the water in the mounting seat 33, spraying it out through the through-hole 121. The through-hole 121 is positioned in the middle of multiple air outlet holes 122, placing the spray in the middle of the airflow generated by the fan assembly 20. 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 10, a fan assembly 20, and a spray device 30, where the housing assembly 10 has a handheld part and an air duct at one end of the handheld part, the fan assembly 20 is installed in the air duct, and the air outlet cover 12 is installed at one end of the air duct, having a through-hole 121 and multiple air outlet holes 122 surrounding the through-hole 121. The spray device 30 includes a water tank 31, a water pipe 32, a mounting seat 33, a fiber water guide, and an atomizer. The water tank 31 is set within the housing assembly 10. The water pipe 32 connects the water tank 31 and the mounting seat 33. The mounting seat 33 is located at the through-hole 121. The atomizer is installed on the mounting seat 33 and exposed through the through-hole 121. The fiber water guide is installed in the water pipe 32. The fiber water guide extends from the water tank 31 to the atomizer. Even if the water pipe 32 is narrow, the fiber water guide continuously guides water from the water tank 31 to the atomizer in the mounting seat 33. This ensures the atomizer does not face interruptions in the spray process, and the mounting seat 33 at the through-hole 121, with the through-hole 121 positioned centrally among multiple air outlet holes 122, ensures the spray is centered in the airflow generated by the fan assembly 20. Compared to sprays located above or below the airflow, this central positioning prevents the spray from being blown away, allowing better integration with the airflow and enhancing spray stability.

In some embodiments, the water tank 31 is positioned at the end of the air outlet cover 12 furthest from the handheld part. Specifically, positioning the water tank 31 at the air outlet cover 12 prevents the water tank 31 from increasing the size of the handheld part, making it easier to hold.

In some embodiments, the water tank 31 is arc-shaped with an opening facing the handheld part, and its inner surface adheres to the upper end of the air outlet cover 12. The mounting seat 33 is spaced below the water tank 31, and the water pipe 32 connects the mounting seat 33 and the end of the water tank 31. Specifically, the air outlet cover 12 and the water tank 31 are both arc-shaped and fit together, preventing the water tank 31 from protruding from the air outlet cover 12.

In some embodiments, the water pipe 32 is split into two, positioned on either side of the mounting seat 33, with one water pipe 32 connecting one end of the water tank 31 to the mounting seat 33 and the other water pipe 32 connecting the other end of the water tank 31 to the mounting seat 33. Specifically, the fiber water guides in the two water pipes 32 transport water from the water tank 31 to the atomizer, ensuring faster and more efficient water transport.

In some embodiments, the housing assembly 10 includes a handheld base 11 and an air outlet cover 12, with the handheld base 11 forming the handheld part and the air outlet cover 12 rotatably installed on the handheld base 11. Specifically, the fan assembly 20 includes a fan motor and fan blades, with the fan motor installed inside the air outlet cover 12 and the fan blades installed on the fan motor's rotating shaft. When the air outlet cover 12 rotates relative to the handheld base 11, the fan motor and fan blades rotate together with the air outlet cover 12, allowing adjustment of the airflow angle by rotating the air outlet cover 12, providing convenience to the user.

In some embodiments, the upper end of the handheld base 11 has two spaced mounting plates 114, each with a rotation part 115, and the air outlet cover 12 is installed between the rotation parts 115. Specifically, installing the air outlet cover 12 between two mounting plates 114, compared to one-sided installation, provides more stability during rotation.

In some embodiments, the water tank 31, water pipe 32, and mounting seat 33 form an integrated unit. Specifically, this simplifies the molding process for the water tank 31, water pipe 32, and mounting seat 33, making the assembly of the handheld spray fan more convenient.

In some embodiments, the spray device 30 comprises detachable front and rear shells 34 and 35 forming the water tank 31, water pipe 32, and mounting seat 33. Specifically, this allows for easy replacement of the fiber water guide if it is damaged and facilitates cleaning when foreign objects enter the water tank 31, water pipe 32, or mounting seat 33.

In some embodiments, the spray device 30 also includes sealing cotton attached to the back of the atomizer. Specifically, when the water tank 31 is positioned above the mounting seat 33, the water pressure at the through-hole 121 is high, and the sealing cotton prevents water from leaking from the back of the atomizer.

In some embodiments, the upper end of the air outlet cover 12 has a limit slot 123, with the water tank 31 abutting against opposite side walls of the limit slot. Specifically, the water tank 31 is secured by the limit slot 123, preventing shaking during use, making the handheld spray fan more stable.
