[0028] In order to make the purpose, technical solution and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present disclosure. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0030] The preferred embodiments of the neck hanging fan according to the present disclosure will be described in detail below with reference to the accompanying drawings.

[0031] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present disclosure may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, without departing from the concept of the present disclosure, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0032] A neck-hanging fan is a portable fan worn around the neck. One known neck-hanging fan features multiple fans installed on the neck-hanging component that contacts the neck, blowing air at multiple locations around the user's neck. To improve cooling efficiency, it's known to install semiconductor cooling chips on the neck-hanging component for active cooling. However, these chips require a high power rating, increasing power consumption.

[0033] Furthermore, it is also known to install an integrally molded cooling element filled with a heat-absorbing medium on the neck strap. This cooling element is formed into an arc shape that fits the neck and is sealed using a heat-absorbing medium after being filled. However, the manufacturing process of this cooling element is complex and relatively expensive. In addition, this cooling element is usually connected to the fan assembly via a connector. If the user wishes to replace the cooling element with a new one, the cooling element must be removed from the fan assembly, making replacement troublesome.

[0034] Elements filled with heat-absorbing media, such as phase change materials, gel materials or oil, can absorb heat through the transformation of solid-liquid properties or their own high specific heat capacity. Such heat-absorbing elements can be attached to the human body to cool down and provide a refreshing effect.

[0035] To address the shortcomings of existing technologies, the present disclosure proposes a novel neck-hanging fan that detachably connects a structurally optimized neck-hanging component and a fan. The curved body of the neck-hanging component is equipped with multiple cooling units spaced apart. These cooling units have a simple structure, low manufacturing cost, and are easy to replace. The following describes exemplary embodiments of the neck-hanging fan proposed in the present disclosure with reference to the accompanying drawings.

[0036] Figures 1 to 11 FIG. 1 shows a preferred embodiment of a neck hanging fan according to at least one embodiment of the present disclosure. Figure 1 As shown, the neck hanging fan includes a fan assembly 1 and a neck hanging part 2. Figure 1 and Figure 2 In the illustrated embodiment, two fan assemblies 1 are shown, but the number of fan assemblies may be more or less, and the present disclosure is not limited thereto.

[0037] like Figure 1 、 Figure 2 and Figure 10 As shown, the fan assembly 1 may include a housing 11 and a fan 12 disposed within the housing. The housing 11 has a generally cylindrical profile and is provided with an air inlet 13 and an air outlet 14. Air can enter the housing 11 through the air inlet 13. The air outlet 14 is disposed around the circumferential sidewall of the housing 11 and is preferably directed toward the neck or face of the human body. Exemplarily, the air outlet 14 includes a plurality of through slots arranged in parallel along the circumferential sidewall.

[0038] To illustrate the structure of the fan assembly 1, Figure 10 Part of the shell is omitted. Figure 10 As shown, a fan blade assembly 111 is provided in the housing 11, and the fan blade assembly 111 is driven to rotate by a drive motor, thereby generating airflow and continuously outputting airflow to the human body. In order to facilitate the discharge of air from the side wall of the housing 11, the distance from the edge of the fan blade assembly 11 to the inner wall of the housing 11 is arranged to be distributed in an involute curve, and the maximum distance is reached at the air outlet 14. For the sake of simplicity, the present disclosure omits other elements of the fan assembly 1 that are less relevant to the concept of the present disclosure, such as the drive motor, battery, control circuit board, wires and other common elements of the fan assembly. Those skilled in the art can adjust and set them according to actual needs.

[0039] The neck-hanging component 2 is formed as a whole into an arc shape that fits the human neck, and includes a first end 21, a second end 22, and an arc-shaped body 23 extending between the first end 21 and the second end 22. A cooling component 3 is provided on the surface of the arc-shaped body 23 of the neck-hanging component 2 close to the human neck, so that it can be worn comfortably on the human neck, and the cooling component 3 fits the skin surface at the neck. The cooling component 3 includes a plurality of cooling units 31 distributed at intervals. The cooling units 31 are made of a polymer material, such as polyurethane (TPU) material, and each cooling unit is filled with a heat-absorbing medium. The heat-absorbing medium can be, for example, a phase change material, a gel material, or oil.

[0040] "Spaced distribution" refers to the presence of gaps between adjacent cooling units 31. For cooling units 31 mounted on the curved body 23, this spacing ensures that there are gaps between the cooling units 31 even when the overall shape is curved. This spaced distribution of cooling units 31 offers significant advantages in manufacturing costs and replaceability. Figure 4 FIG. 4 shows a front view of the cooling element 3. Figure 4 As shown, the multiple cooling units 31 of the cooling component 3 can be connected to each other through a connector 32, and the heat absorbing medium between the multiple cooling units 31 is not connected, so as to prevent crosstalk between the heat absorbing media, simplify the processing technology and reduce the manufacturing cost. The cooling unit 31 can have an opening, which is sealed by hot pressing after the phase change material is poured. The cooling component 3 can be made of a flexible material and formed into a specific arc shape by bending. For example Figure 5 and Figure 6 As shown, in order to install the cooling component 3, the arc-shaped main body 23 is provided with a mounting groove 4 on the surface close to the human neck. The cooling component 3 can be set in the mounting groove 4, for example, the connecting member 32 is set in the mounting groove 4, and the cooling unit 31 protrudes toward the inside.

[0041] Alternatively, in an embodiment not shown, the plurality of cooling units 31 may be separate parts, independent of each other, and respectively disposed in corresponding mounting slots 4. This embodiment has the advantage that a cooling unit 31 can be replaced individually without disassembling the entire cooling component 3.

[0042] Phase change materials (PCMs) are substances that change form with temperature and can generate latent heat. The process by which a PCM changes from solid to liquid or vice versa is called a phase change, during which the PCM absorbs or releases a significant amount of latent heat. Water is the most common PCM. When the temperature drops below 0°C, water changes from liquid to solid (freezing). When the temperature rises above 0°C, water changes from solid to liquid (melting). During the freezing process, it absorbs and stores a significant amount of cold energy, while during the melting process, it absorbs a significant amount of heat energy. For this embodiment, in addition to water, the preferred phase change material can be a solid-liquid phase change material with a phase change temperature (or freezing point) around room temperature (16°C to 33°C), such as higher aliphatic hydrocarbons (n-hexadecane, n-octadecane, paraffin, etc.), fatty acids and their esters (stearic acid, palmitic acid, etc.), crystalline hydrated salts (Na2SO4·10H2O, Mn(NO3)2·6H2O, etc.), molten salts (LiF, NaF, CaF2, etc.), metals and alloys (lead-tin alloy, etc.) and polymers (polyethylene glycol, etc.).

[0043] The neck hanging part 2 is connected to the fan assembly 1 via the first end 21 and / or the second end 22. Specifically, the first end 21 and / or the second end 22 are detachably connected to the housing 11, thereby allowing the fan assembly 1 to be installed on or removed from the neck hanging part 2. Figures 7 to 11 As shown, the first end portion 21 and the second end portion 22 are at least partially inserted into the housing 11 and are respectively connected to the housing 11 by snap fasteners. Specifically, the first end portion 21 and the second end portion 22 are provided with elastic protrusions 5, and one end of the housing 11 is provided with an opening 111 for accommodating the first end portion 21 and / or the second end portion 22, and the surface of the housing 11 is also provided with a slot 112 for accommodating the elastic protrusion 5.

[0044] In an exemplary embodiment, the neck hanging fan comprises two fan assemblies 1 and a neck hanging part 2, and the first end 21 and the second end 22 of the neck hanging part 2 are detachably connected to the two fan assemblies 1 respectively. Figure 8 Cross-sectional view combined with Figure 11As shown, when installed, the first end 21 and the second end 22 are inserted into the opening 111 of the housing 11, and the elastic protrusion 5 is engaged with the slot 112 of the housing 11. When the fan assembly 1 needs to be disassembled, the user can press the elastic protrusion 5 and pull the fan assembly 1 away from the first end 21 or the second end 22, thereby separating the fan assembly 1 from the neck hanging component 2.

[0045] Furthermore, the cooling component 3 is detachably connected to the curved body 23, for example, by being installed to the curved body 23 through an interference fit, or by being connected to the curved body 23 through an adhesive or glue. When the neck halter 2 and the fan assembly 1 are connected, the cooling component 3 can still be removed from the neck halter 2 independently, and the cooling component 3 can be replaced without separating the neck halter 2 from the fan assembly 1.

[0046] During actual use, the cooling component 3 filled with phase-change material can be first stored at a low temperature for a period of time and then removed, at which point the phase-change material is in a solid state. The cooling component 3 is then connected to the neck hanging component 2, which is then connected to the fan assembly 1, so that it can be hung around the human neck for cooling and ventilation. Because the cooling component 3 and the neck hanging component 2 are detachably connected, when the temperature of the phase-change material in the cooling component 3 approaches room temperature and the cooling effect deteriorates, the cooling component 3 can be removed and replaced with a new cooling component 3 that has been stored at a low temperature, making replacement convenient.

[0047] While exemplary implementations of the neck-hanging fan proposed in the present disclosure have been described in detail with reference to preferred embodiments, those skilled in the art will appreciate that various modifications and variations may be made to the aforementioned specific embodiments without departing from the principles of the present disclosure. Furthermore, various combinations of the various technical features and structures proposed in various aspects of the present disclosure may be made without departing from the scope of protection of the present disclosure, which is determined by the appended claims.
