[0037] Refer to Figures 3 to 5 , the refrigeration structure of the cold fan includes cooling bag 600 and mounting bracket 700, and the cooling bag 600 is provided with a cavity 605 for storing cooling liquid, and the cooling bag 600 is also provided with a plurality of airflow through holes 601 for airflow to pass through and exchange heat with the cooling liquid in the cavity. Specifically, the cooling liquid can be ice water, refrigerant, etc., or ice block, specifically, water is filled into the cavity, and then the cooling bag 600 is placed in the refrigerator to freeze ice blocks. The mounting bracket 700 is provided with a limiting piece 710 for mounting and limiting the cooling bag 600, and the bottom end of the mounting bracket 700 is provided with a water tank 720 for receiving water droplets condensed from the cooling bag 600.

[0038] The cold fan of the above embodiment can add cooling liquid or other refrigerant in the cavity of the cooling bag. The cooling bag 600 is mounted to the mounting bracket 700. When cooling wind, the airflow exchanges heat with the cooling liquid or ice block in the cooling bag 600 through the airflow through hole 601, so that the airflow output from the airflow through hole 601 is cooled by heat absorption. The moisture in the airflow or the moisture in the air will condense on the cooling bag 600, and when the condensed water is more, it will drip down along the side wall of the cooling bag 600 into the water tank 720, achieving water flow collection and avoiding the condensed water flowing to other positions, which plays a good protective role for the fan and makes the environment dry.

[0039] Further, refer to Figure 2 and Figure 3The inner side of the rear net 500 is provided with a mounting position 501, the mounting position 501 is arranged in a plurality of clamping grooves 502, the mounting frame 700 is provided with a plurality of elastic buckles 701 on the side away from the limiting member 710, which is used to be buckled with the clamping grooves 502; one end of the limiting member 710 further extends a hand holding position 712. In this embodiment, the cooling bag 600 is mounted on the rear net 500 through the mounting frame 700, and the cooling bag 600 is mounted on the rear net 500, which is simple in structure and convenient to operate. In addition, the mounting frame 700 is more convenient to disassemble and assemble through the hand holding position 712.

[0040] Further, the mounting frame 700 is a frame body and surrounds a hollow structure. Therefore, when the cooling bag 600 is mounted on one side of the mounting frame 700, the airflow enters the airflow through hole 601 of the cooling bag 600 from the hollow part of the frame body. Preferably, the mounting frame 700 is a ring-shaped or semi-ring-shaped structure.

[0041] Further, with reference to Figures 4 to 7 , one side of the mounting frame 700 is further provided with a concave cavity 702, the concave cavity 702 makes the mounting frame 700 form an outer ring side wall 703 and an inner ring side wall 704; the water tank 720 is arranged on the bottom end side of the outer ring side wall 703. In this embodiment, the cooling fan will swing up and down during actual operation, so the water in the water tank 720 will enter the concave cavity 702, thereby effectively avoiding the phenomenon of water overflowing from the water tank 720.

[0042] Further, with reference to Figure 6 and Figure 7 , the limiting member 710 includes two elastic arms 711 arranged opposite to the two sides of the outer ring side wall, the two elastic arms 711 and the water tank 720 form a fixed position for accommodating the cooling bag 600, which is used to support and limit the cooling bag 600. The free end of the elastic arm 711 is provided with a limiting part 713 extending to the inner side of the fixed position. In this embodiment, the bottom of the cooling bag 600 is supported on the water tank 720, and the cooling bag 600 is clamped by the two elastic arms 711, the limiting part 713 of the elastic arm 711 limits the cooling bag 600, so as to achieve stable support of the cooling bag 600 and enable the cooling bag 600 to contact the airflow with the maximum area. In addition, the cooling bag 600 is supported by three points, which is simple in structure and convenient to disassemble and assemble.

[0043] Further, with reference to Figure 6 and Figure 7 , the water tank 720 includes a bottom plate 721, the bottom plate 721 extends from the bottom end side of the outer ring side wall 703, and the end of the bottom plate 721 away from the mounting frame 700 forms an extension with a side plate 722.

[0044] Further, the bottom plate 721 is a circular arc plate which is curved and extended upward at both ends. When the cooling bag 600 is supported on the water tank 720, both ends of the cooling bag 600 are supported on both ends of the bottom plate 721, and the inner side of the side plate 722 limits the cooling bag 600, so that the cooling bag 600 can be suspended above the water tank 720, and the water tank 720 can hold more water.

[0045] Further, in order to reduce the contact area between the side plate 722 and the cooling bag 600, and to make the water condensed on the cooling bag 600 flow better into the water tank 720, a convex point 723 is further arranged on the inner side of the side plate 722. Please refer to Figure 7 , the side wall of the cooling bag 600 is supported by the convex point 723. The cooling bag 600 and the inner side of the side plate 722 form a gap, and the water flow can flow downward from the gap, avoiding the problem that the water flow on the outer side of the cooling bag 600 drips downward along the side plate 722.

[0046] Further, referring to Figure 8 , the side of the cooling bag 600 which is attached to the mounting frame 700 is inwardly recessed to form an inner spherical surface 602, and the other side of the cooling bag 600 is outwardly arched to form an outer spherical surface 603. When the cooling fan swings up and down, the water flow condensed on the surface of the cooling bag 600 can flow downward along the spherical surface under the action of gravity, facilitating the collection of the collected water. In addition, the inner side of the cooling bag 600 forms an inner spherical surface, so that there is a certain arched gap between the inner side of the cooling bag 600 and the mounting frame 700, which is more convenient for the accumulated water to flow into the water tank 720.

[0047] Further, referring to Figure 8 , the two ports of the air flow through hole 601 are provided with water stop rings 604. The water stop rings 604 can form a water retaining dam, which can effectively prevent the accumulated water from entering the air flow through hole 601 and being sucked into the fan blade along the air flow.

[0048] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
