[0002] In hot seasons, cooling fans, as a common device for cooling the air, bring coolness to people and are widely used in many environments such as homes, offices, and commercial places. Cooling fans usually use the method of directly blowing dry cold air from the fan to cool the air. Although it can effectively reduce the air temperature, due to the lack of appropriate humidification methods, the cold air generated is relatively dry.

[0003] For example, the Chinese utility model patent with patent number 202222927402.9 provides a cooling fan, which is provided with an air inlet, an air outlet, a fan, an atomizing channel, a water curtain and an atomizing chamber. When in use, air is blown out through the fan between the air inlet and the air outlet, and a water curtain is provided on one side of the air inlet to cool down. After water forms water mist in the atomizing chamber, it is blown out through the atomizing channel toward the fan; however, traditional cooling fans generally have a mist particle spraying device inside the body, which is prone to water accumulation or water mist residue inside. Long-term water mist residue will corrode the internal components of the equipment, reduce the service life of the equipment, and increase maintenance costs. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a cooling fan with improved cooling effect, so as to solve the technical problems in the prior art that traditional cooling fans generally have a mist spraying device inside the body, which easily forms accumulated water or water mist residue inside.

[0027] Please refer to Figure 3 and Figure 4 As shown, a top cover 41 is provided on the top of the shell 11, and a water drop chamber 42 is opened on the top of the top cover 41. At the same time, a water storage base 43 is provided on the bottom of the shell 11, and a water storage chamber 44 is opened on the top. The water storage chamber 44 is connected to the water drop chamber 42 and the mist spraying device 31 through a pipeline, and a water pump 45 is provided on the pipeline. By starting the water pump 45, the water in the water storage chamber 44 is transported to the water drop chamber 42 and the mist spraying device 31, so that the mist spraying device 31 directly emits water mist to the outside along the air outlet 13.

[0028] Please refer to Figure 5 As shown, the spray assembly also includes a support base 32, which is arranged at the bottom of the air outlet 13, and the bottom of the mist spraying device 31 is connected to the support base 32; it provides reliable support for the mist spraying device 31; during the operation of the cooling fan, the mist spraying device 31 will be subjected to a certain wind pressure and is prone to displacement or vibration. The setting of the support base 32 can firmly fix the position of the mist spraying device 31, and can also withstand the impact force from the airflow, ensuring that the mist spraying device 31 can work stably.

[0029] Please refer to Figure 2As shown, a humidifying component is provided in the shell 11, and the humidifying component includes a first water curtain 21 and two groups of second water curtains 22, wherein the first water curtain 21 is arranged on one side of the first air inlet 14, and second air inlets 16 are opened on both sides of the shell 11, and two groups of second water curtains 22 are respectively provided on the adjacent side of the two groups of second air inlets 16; through the arrangement of the first water curtain 21 and the two groups of second water curtains 22, when the external hot and dry air enters the interior of the cooling fan through these air inlets, it will first be moistened by the water curtains, thereby being pre-cooled and humidified; in this way, the cold air discharged from the air outlet 13 not only has a lower temperature, but also has a higher humidity, thereby improving the cooling and humidifying performance of the whole machine; on the opposite side of the second air inlet 16, a dust shield 17 is also provided to prevent external dust from entering the interior of the cooling fan, protect the humidifying component from pollution, and ensure that the water curtain can maintain a good humidification effect for a long time.

[0030] Please refer to Figure 2 and Figure 3 As shown, the top of the top cover 41 is provided with a drip groove 46, and a through groove is provided on one side of the water drop chamber 42 to connect to the drip groove 46. In this way, the water accumulated in the water drop chamber 42 can flow smoothly into the drip groove 46. The bottom of the drip groove 46 corresponds to the first water curtain 21 and the two sets of second water curtains 22. It also has multiple sets of drip holes. These drip holes can drip the water in the drip groove 46 onto the surface of each water curtain in a targeted manner, and eventually flow back into the water storage chamber 44. This ensures that the water can be recycled, reduces the daily water replenishment needs, and improves the convenience of the entire machine. To facilitate the user's water addition operation, two sets of switchable top plates 47 are set on the top of the water drop chamber 42. Simply opening these top plates 47 can directly inject water into the water drop chamber 42, completing the water addition process of the fan.
