[0017] In this embodiment, the portable atomizing spray fan is equipped with a dual-purpose liquid storage container 4. When in use, the base module 2 is attached to the open end of the liquid storage container 4 in the forward direction, and the liquid storage container 4 is positioned at the bottom of the fan module 1 (as shown in FIG. 1). The base module 2 and the liquid storage container 4 are locked together using the bidirectional rotating locking pin 212 installed in the first locking hole 211 and the second locking hole 41, improving the stability of the assembled product. When the fan is started, the water pumping module is used to pump the liquid in the liquid storage container 4 to the atomizing nozzle 16, which then atomizes the liquid and discharges it (the atomizing nozzle 16). The amount of atomization can be achieved by adjusting the number of times the atomizing nozzle 16 is opened and closed according to actual needs), and the mist is blown onto the human body along with the wind blown out by the blades 13, thereby achieving a faster cooling effect. When transporting or not in use, the base module 2 is attached to the open end of the liquid storage container 4 in the reverse direction to store the fan module 1 inside the liquid storage container 4 (as shown in Figure 2), and the bidirectional rotating locking pin 212 installed in the first locking hole 211 and the second locking hole 41 can be used to lock the base module 2 and the liquid storage container 4, reducing the installation space and making transportation and daily storage more convenient, thereby improving the practicality of the spray fan.

[0018] In this embodiment, the water pumping module includes a water pump 231, a supply pipe 232, and a drain pipe 233. The water pump 231 is fixed in the housing 21. One end of the supply pipe 232 communicates with the supply port of the water pump 231. The other end of the supply pipe 232 passes through the base 22 and extends into the liquid storage container 4 (when the fan module 1 is stored in the liquid storage container 4, the supply pipe 232 is fitted into a groove formed in the base 22). One end of the drain pipe 233 communicates with the drain port of the water pump 231. The other end of the drain pipe 233 passes through the rotary support shaft 3 and extends to the atomizing nozzle 16, and communicates with the atomizing nozzle 16.

[0019] In this embodiment, the fan module 1 includes a casing, a blade 13, a first drive motor 14, and a liquid storage tank 15. The casing includes a front casing 11 and a rear casing 12. The bottom of the rear casing 12 is mounted on the base module 2 via a rotation support shaft 3. The blades 13 and the first drive motor 14 are mounted in the casing.

[0020] The water pumping module of this embodiment adopts the above-mentioned specific structure. When in use, the water pump 231 is started to suck in the liquid in the liquid storage container 4 through the supply pipe 232 and pump it through the drain pipe 233 into the liquid storage tank 15. (The pressure release valve can effectively control the pressure of the liquid or gas in the liquid storage tank 15, preventing the liquid or gas in the liquid storage tank 15 from being discharged in a timely manner, resulting in excessive internal pressure and damaging the liquid storage tank 15 or other related components. When the pressure is released, the excess liquid or gas flows out through the pressure release valve and into the pressure release pipe 234, and after passing through the pressure release pipe 234, it flows back into the liquid storage container 4, thereby achieving pressure relief.) The liquid is then atomized by the atomizing nozzle 16 and discharged. The mist is then blown onto the human body along with the wind blown by the blades 13, achieving a faster cooling effect.

[0021] In this embodiment, the base module 2 further includes a second drive motor 24, a control circuit board 25 (the control circuit board 25 has built-in control programs, including but not limited to, programs for controlling the rotation speed of the blades 13, the left and right swing of the casing, the power of the water pump 231, and the opening and closing of the atomizing nozzle 16), and a battery module 26. The second drive motor 24 is fixed in the base 22, and the power output end of the second drive motor 24 is connected to the rotary support shaft 3. The second drive motor 24 drives the rotary support shaft 3 to rotate in the forward or reverse direction and also drives the left and right swing of the fan head. The control circuit board 25 is fixed in the housing 21, and a key 27 for controlling the operation of the fan is installed on the control circuit board 25 and extends outward. The first drive motor 14, the second drive motor 24, and the battery module 26 are all electrically connected to the control circuit board 25.

[0022] In this embodiment, a rotatable handle 28 is installed at the lower end of the base 22, and a storage groove 221 is recessed in the lower end surface of the base 22 corresponding to the handle 28. When the fan is not in use, the handle 28 can be stored in the storage groove 221 (see FIG. 2). When the fan is to be transported, the user can rotate the handle 28 and pull it out of the storage groove 221 so that the user can hold the handle 28 and transport the fan.
