[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] like Figures 1 to 6 As shown, this utility model provides a novel spray fan, including a housing 1 and a spray device 2, a fan assembly 3, and a water tank 4 housed within the housing 1. The spray device 2 is located at the air outlet of the fan assembly 3, and the water tank 4 is located above the spray device 2. The drain hole 4a at the bottom of the water tank 4 is connected to the water inlet 2a of the spray device 2 via a pipe for supplying water to the spray device 2. An air outlet 1a is provided on one side of the housing 1, and an air inlet 1b is provided on the other side of the housing 1. The air inlet of the fan assembly 3 is connected to the air inlet 1b, and the air outlet of the fan assembly 3 and the spray hole 2b of the spray device 2 are respectively connected to the air outlet 1a. When the fan assembly 3 is started, outside air is drawn into the housing from the air inlet 1b and then discharged through the air outlet 1a. At the same time, the spray device atomizes water and discharges it from its spray hole 2b and then from the air outlet 1a. The two are fully mixed in the environment, improving the utilization rate of the water mist and providing a better user experience.

[0039] As a further preferred embodiment of this utility model, an annular air outlet channel 3a is provided at the air outlet end of the fan assembly 3. The spray hole 2b of the spray device 2 is located within the area surrounded by the air outlet channel 3a and in the middle area of ​​the air outlet 1a. The airflow generated by the fan assembly 3 is discharged from the annular air outlet channel 3a, and the water mist is sprayed out in the middle of the air outlet 1a, completing the mixing with the annular airflow, and the generated water mist is not lost.

[0040] The structure of the spray device 2 is as follows: Figure 2 and Figure 5 As shown, the device includes a water tank 21, an atomizing plate 22, a sealing ring 23, and a panel 24. A spray hole 2b is located in the central area of ​​the panel 24. An opening 21a is located on one side of the water tank 21. The sealing ring 23 is fitted around the outer periphery of the atomizing plate 22 and is sealed within the opening 21a. The atomizing plate 22 contacts the water in the water tank and atomizes the water through vibration before discharging it. The atomizing plate utilizes existing technology; its specific principle and structure will not be detailed here. The panel 24 is fixedly connected to the water tank 21. The opening 21a on the water tank 21 corresponds to the spray hole 2b on the panel 24. The atomizing plate 22 atomizes the water and sprays it out from the spray hole 2b on the panel 24, where it mixes with the airflow blown out from the annular air outlet channel.

[0041] The housing 1 includes a front housing 11 and a rear housing 12 that are detachably and fixedly connected. An air outlet 1a is located on the front housing 11, and an air inlet 1b is located on the rear housing 12. An air inlet grille 121 is provided at the air inlet 1b. A water tank 4 is preferably located at the top of the front housing 11 and the rear housing 12, and a top cover 5 is provided on the water tank 4. The air outlet is preferably a circular hole, and the panel 24 is disc-shaped and located at the air outlet 1a. Figure 1 and Figure 3 As shown, an annular gap a is formed between the edge of the panel 24 and the air outlet 1a to allow the fan assembly 3 to discharge air. In other words, the outer diameter of the panel is smaller than the diameter of the air outlet, and the airflow discharged from the air outlet channel passes through the annular gap a and is discharged into the environment.

[0042] like Figure 6 As shown, a second vent 4b and a drain hole 4a are provided at the bottom of the water tank 4; Figure 5 As shown, a first vent 2c and a water inlet 2a are provided at the top of the water tank 21. A first vent pipe 211 and a second vent pipe 41 extending upward are respectively provided at the first vent 2c and the second vent 4b. The first vent pipe 211 and the second vent pipe 41 are connected by a flexible tube, preferably a silicone tube.

[0043] like Figure 2 , 3 As shown in Figure 4, the fan assembly 3 includes a bracket 31, a fan 32, and an air duct 33. The fan 32, air duct 33, and panel 24 are fixedly connected to the bracket 31. The fan 32 is located inside the air duct 33. The spray device 2 is located at the air outlet of the fan 32. The air duct 33 is connected to the air inlet 1b. The bracket 31 is fixedly connected to the inner side of the front shell 11. The bracket 31 is as follows... Figure 2 As shown, it includes a vertical support plate and an air outlet channel arranged along the edge of the support plate. A fan 32, an air duct 33, and mounting holes for the panel 24 are provided on the support plate. Mounting holes for fixed connection with the front housing 11 are also provided on the bracket 31. Preferably, the fan 32 and the spray device 2 are fixed to both sides of the bracket 31, and the airflow generated by the fan 32 is blown out through the air outlet channel 3a and the air outlet 1a.

[0044] When the fan needs to work, the fan is powered on and rotates at high speed, driving air to be drawn in through the air inlet grille, blown out through the air duct, air outlet duct and circular air outlet, thus realizing the fan function.

[0045] When spraying is needed, open the top cover and add an appropriate amount of water to the water tank. The water flows into the water trough through the drain hole and the inlet hole. At this time, the atomizing plate works, atomizing the water and spraying it out from the spray hole. It mixes with the air blown out from the circular air outlet. The water mist absorbs the heat in the air, lowers the air temperature, and is blown out together, achieving the cooling effect of the spray fan.

[0046] Any aspects not covered in this utility model are applicable to the prior art.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
