Detailed implementation manners

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0028] As Figures 1 to 8 shown, the present invention provides a specific embodiment of a neck fan.

[0029] A neck fan, referring to Figure 1 , the neck fan includes an arc-shaped column 100, a first extension cord 200, a second extension cord 300, a first fan unit 230, and a second fan unit 330. One end of the first extension cord 200 is connected to the first fan unit 230, and the other end of the first extension cord 200 is detachably connected to the arc-shaped column 100. One end of the second extension cord 300 is connected to the second fan unit 330, and the other end of the second extension cord 300 is detachably connected to the arc-shaped column 100; wherein, the arc-shaped column 100 is filled with a phase change material.

[0030] Specifically, referring to Figure 1 , the first fan unit 230 and the second fan unit 330 can accelerate the convection of the surrounding air by generating air flow, helping to dissipate heat and reducing the problems of the surrounding environment, so as to help the skin dissipate heat; the first extension cord 200 is used to connect the arc-shaped column 100 and the first fan unit 230, and the second extension cord 300 is used to connect the arc-shaped column 100 and the second fan unit 330. The user can hang the first fan unit 230 and the second fan unit 330 around the neck through the arc-shaped column 100.

[0031] Furthermore, referring to Figure 1 , both the first extension cord 200 and the second extension cord 300 are detachably connected to the arc-shaped column 100. The existing neck fans generally design the neck strap and the fan as an integrated structure, which cannot be disassembled, making it inconvenient to carry and store. By setting the first extension cord 200 and the second extension cord 300 used to connect the first fan unit 230 and the second fan unit 330 respectively as detachable structures, the first fan unit 230 and the second fan unit 330 can be disassembled when not in use, facilitating carrying and daily storage. Being set as detachable can also use the first fan unit 230 or the second fan unit 330 alone, making the neck fan more practical.

[0032] Furthermore, the arc-shaped column 100 is filled with a phase change material, which is a special material that can absorb or release a large amount of heat within a specific temperature range, thereby achieving temperature regulation and thermal energy storage. The phase change material utilizes the latent heat absorbed or released during the phase change process of a substance to regulate temperature. During the phase change process, when the material changes from a solid state to a liquid state, it absorbs latent heat; when it changes from a liquid state to a solid state, it releases latent heat. This property enables the phase change material to be used as a heat insulation material to regulate temperature by utilizing its property of absorbing or releasing heat.

[0033] Among them, before using the neck fan, the arc-shaped column 100 can be disassembled and placed in the refrigerator for cooling and refrigeration. When in need of use, the refrigerated arc-shaped column 100 is then installed between the first fan unit 230 and the second fan unit 330. In this way, when the neck fan is hung around the neck, the arc-shaped column 100 can quickly absorb heat to help cool the neck, and due to the special effect of the phase change material, its temperature rise is extremely slow and it can maintain a low temperature state for a long time.

[0034] In this embodiment, by designing a neck fan, including an arc-shaped column 100, a first extension cord 200, a second extension cord 300, a first fan unit 230, and a second fan unit 330, one end of the first extension cord 200 is connected to the first fan unit 230, the other end of the first extension cord 200 is detachably connected to the arc-shaped column 100, one end of the second extension cord 300 is connected to the second fan unit 330, the other end of the second extension cord 300 is detachably connected to the arc-shaped column 100, and the arc-shaped column 100 is filled with a phase change material. By setting the arc-shaped column to be detachably connected at both ends, it can be disassembled during non-use time to facilitate daily storage and outdoor carrying. Furthermore, by filling the arc-shaped column with a phase change material and utilizing the properties of the phase change material for temperature regulation, when the neck fan is hung around the neck, the arc-shaped column can effectively cool the neck to improve the cooling effect and make the heat dissipation more comprehensive.

[0035] In one of the embodiments, referring to Figure 1 and Figure 2 , a first connection part 400 is provided between the arc-shaped column 100 and the first extension cord 200.
