Description

Technical Field

[0001] The present invention relates to the technical field of spray fans, and specifically to spray cooling fans.

Background Art

[0002] A spray fan refers to a product in which a spray device is provided on a fan body. After the spray device atomizes water, the water mist is diffused outward by the flow of air generated from the fan body, thereby achieving a better temperature reduction effect and increasing the environmental air humidity.

[0003] Normally, a spray fan forms a water mist by atomizing liquid water using an ultrasonic atomization sheet and then sprays it out. Therefore, in order to supply a water source for the operation of the ultrasonic atomization sheet on the premise of not impairing portability, it is necessary to integrally provide a water storage tank on the spray fan body. However, in the field of portable fans, the capacity of the water storage tank is greatly limited. When the capacity of the water storage tank increases, the appearance of the product becomes very unnatural and looks bad. When the water storage tank becomes small, it cannot meet the demand for the atomization operation, and it is necessary to frequently add water to the water storage tank. This causes a contradiction between practicality and portability, which is a problem that those skilled in the art must quickly solve.
