[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figure 1 , Figure 2 and Figure 3This utility model provides a neck fan that can be worn around the neck to regulate neck temperature, such as for cooling. The neck fan includes a wearing bracket 10, a fan 20, and a cover plate 30. The wearing bracket 10 has a first air inlet 110 and an air outlet 120; the fan 20 is located inside the wearing bracket 10 and exposed to the first air inlet 110; the cover plate 30 is corresponding to the first air inlet 110 and is movably connected to the wearing bracket 10 to expose or cover the fan 20; when the cover plate 30 is covering the fan 20, an air intake channel 40 is formed between the cover plate 30 and the wearing bracket 10, and the air intake channel 40 has a second air inlet 410 communicating with the first air inlet 110. The second air inlet 410 can be located on the cover plate 30 or on the wearing bracket 10, as long as it communicates with the first air inlet 110.

[0026] Specifically, when the neck fan is in operation, fan 20 starts, and outside air enters the neck fan through the second air inlet 410 and the first air inlet 110. Fan 20 rotates, causing air to be blown out through the air outlet 120, thus cooling the user. If hair or other foreign objects are sucked into fan 20, the user can open the cover 30 to expose fan 20 and quickly clean it through the first air inlet 110. This prevents performance degradation or damage to fan 20 due to foreign object accumulation, extending product lifespan and reducing maintenance costs.

[0027] The cover plate 30 and the wearing bracket 10 are designed to be movable, so that when the fan 20 is in normal condition, it can completely cover the first air inlet 110, forming a physical barrier to reduce the entry of hair or foreign objects into the fan 20. The cover plate 30 and the wearing bracket 10 can be connected by means of hinges, snaps, sliding, or magnetic attraction.

[0028] In this embodiment, the air outlet 120 is, for example, a strip-shaped hole arranged along the length of the wearing bracket 10, which can prevent the air outlet 120 from exposing the internal structure of the wearing bracket 10. In other embodiments, multiple air outlets 120 are provided, and the multiple air outlets 120 are arranged at equal intervals along the length of the wearing bracket 10 to distribute air evenly and provide users with a better user experience.

[0029] See Figure 2 and Figure 3 In some embodiments, the first end 320 of the cover plate 30 is rotatably connected to the wearing bracket 10 via a rotating shaft 50. The cover plate 30 rotates around the rotating shaft 50, thereby enabling the covering and exposure of the fan 20. The first end 320 of the cover plate 30 engages with the rotating shaft 50 through a shaft hole, forming a stable rotatable connection. This allows the cover plate 30 to fit tightly against the wearing bracket 10 when closed, preventing foreign objects from entering the fan 20, and also facilitating quick opening of the cover plate when the user needs to clean the fan.

[0030] Furthermore, a limiting structure can be provided between the cover plate 30 and the wearing bracket 10. For example, a limiting protrusion is provided on the wearing bracket 10, and a corresponding limiting groove is provided on the cover plate 30. When the cover plate 30 is rotated to a specified angle, the limiting protrusion is engaged in the limiting groove, thereby fixing the position of the cover plate 30 and preventing it from moving accidentally due to external force or vibration.

[0031] See Figure 2 and Figure 3 In some embodiments, the wearing bracket 10 is provided with a first magnetic 130; the first end 320 of the cover plate 30 is rotatably connected to the wearing bracket 10 via a rotating shaft 50, and the second end 330 of the cover plate 30 is provided with a second magnetic 310. The second end 330 of the cover plate 30 can be fixed to the wearing bracket 10 by the magnetic attraction between the first magnetic 130 and the second magnetic 310, preventing the cover plate 30 from loosening or falling off due to external force or vibration during use. It also allows users to easily switch the state of the cover plate 30 according to actual needs. When it is necessary to clean the fan 20, the cover plate 30 can be easily opened to expose the fan 20. During normal use, the cover plate 30 can cover the first air inlet 110 to prevent foreign objects from entering. Among them, the first magnetic 130 and the second magnetic 310 are, for example, magnets, and their magnetic poles are opposite at one end. Alternatively, one of the first magnetic 130 and the second magnetic 310 is, for example, a magnet, and the other is, for example, an object that can be attracted and moved by a magnet, such as iron, nickel, cobalt, or their alloys.

[0032] See Figure 1 In some embodiments, at least one second air inlet 410 is disposed on and penetrates the cover plate 30. Airflow first enters the air intake channel 40 through the second air inlet 410 on the cover plate 30, and then enters the fan 20 through the first air inlet 110.

[0033] See Figure 1 and Figure 5 In some embodiments, there are multiple second air inlets 410. Along the length of the wearing bracket 10, multiple second air inlets 410 are arranged at intervals to form a multi-point air intake structure. This allows airflow to enter the air intake channel 40 evenly from multiple directions, optimizing airflow distribution and flow efficiency. The multi-inlet structure can significantly increase the air intake volume, thereby improving the cooling effect of the fan. At least one second air inlet 410 is formed by the wearing bracket 10 and the cover plate 30.

[0034] See Figure 2 and Figure 3In some embodiments, the wearing bracket 10 includes a first sub-bracket 140 and a second sub-bracket 150, forming a wearing space 160 between the first sub-bracket 140 and the second sub-bracket 150. The first sub-bracket 140 and the second sub-bracket 150 are rotatably connected, allowing the first sub-bracket 140 to rotate left and right relative to the second sub-bracket 150, facilitating user adjustment of the distance between the first sub-bracket 140 and the second sub-bracket 150, i.e., adjusting the size of the wearing space 160. The first sub-bracket 140 and the second sub-bracket 150 are rotatably connected, and the first sub-bracket 140 and the second sub-bracket 150 have identical structures, giving the wearing bracket 10 a symmetrical structure and increasing the product's aesthetics. At least one of the first sub-bracket 140 and the second sub-bracket 150 is provided with a fan 20 and a cover plate 30. The first sub-support 140 and the second sub-support 150 are adapted to the curvature of the human neck. The air outlet 120 is, for example, located in the length direction of the first sub-support 140 or the second sub-support 150, and located on the side of the first sub-support 140 and the second sub-support 150 closer to the human neck.

[0035] See Figure 4 In some embodiments, the fan 20 includes a first fan 210 and a second fan 220, and the cover plate 30 includes a first cover plate 340 and a second cover plate 350. The first fan 210 is located inside the first sub-support 140, and the second fan 220 is located inside the second sub-support 150, which can enhance the cooling efficiency of the neck fan. The first cover plate 340 is movably connected to the first sub-support 140, and the second cover plate 350 is movably connected to the second sub-support 150. Each cover plate 30 corresponds to one fan, forming an independent protective structure. The first cover plate 340 and the second cover plate 350 are rotatably connected to the first sub-support 140 and the second sub-support 150 respectively by sharing the same rotating shaft 50, simplifying the structure and reducing production costs. The first fan 210 and the second fan 220 can be controlled independently, allowing users to choose to operate a single fan or both fans simultaneously according to their actual needs, flexibly adjusting the airflow.

[0036] See Figure 4 and Figure 5 In some embodiments, the first sub-support 140 and the second sub-support 150 are rotatably connected via a common rotating shaft 50. The first sub-support 140, the second sub-support 150, the first cover plate 340, and the second cover plate 350 are designed with the same rotating shaft, ensuring that when the neck fan is opened and closed to adjust the wearing space 160 on both sides—that is, when the first sub-support 140 or the second sub-support 150 rotates in a direction that moves away from or towards each other—the first cover plate 340 and the second cover plate 350 will move along with the first sub-support 140 or the second sub-support 150 connected to it. If hair or foreign objects enter the fan 20, the first cover plate 340 and the second cover plate 350 can be opened, while the first sub-support 140 and the second sub-support 150 remain stationary.

[0037] Furthermore, it also includes a damping component, which can increase the frictional force when the first sub-support 140 rotates relative to the second sub-support 150, ensuring that the first sub-support 140 remains stably stationary at any rotational position relative to the second sub-support 150, and preventing the second sub-support 150 from continuing to rotate relative to the first sub-support 140 without external force. It can also increase the frictional force when the first cover plate 340 rotates relative to the first sub-support 140, ensuring that the first cover plate 340 remains stably stationary at any rotational position relative to the first sub-support 140, and preventing the first cover plate 340 from continuing to rotate when the user is cleaning hair or foreign objects inside the fan 20. The damping component, for example, is a damping ring, fitted around the rotating shaft 50.

[0038] See Figure 4 and Figure 5 In some embodiments, the neck fan further includes a deformable protective sleeve 60, which is disposed between the first sub-support 140 and the second sub-support 150, with the rotating shaft 50 located inside the protective sleeve 60. For example, the protective sleeve 60 has fixed ends at both ends. These fixed ends can be integrally formed with the middle portion or connected via a sleeve. The two fixed ends respectively wrap around and connect to the outside of the first sub-support 140 and the second sub-support 150, and the rotating shaft 50 is inside the protective sleeve 60, preventing it from being exposed. The protective sleeve 60 is made of a soft material such as silicone, which will elastically deform with the rotation of the rotating structure, without affecting the rotation between the first sub-support 140 and the second sub-support 150. The outer surfaces of the two ends of the protective sleeve 60 can be designed to smoothly transition with the outer surfaces of the first sub-support 140 and the second sub-support 150, increasing the product's aesthetics. In order to make it easier for the protective sleeve 60 to bend when the first sub-support 140 and the second sub-support 150 rotate, a crease, such as a groove, can be provided in the middle part of the protective sleeve 60, so that the protective sleeve 60 can be bent and deformed more easily when rotating without affecting the rotation of the rotating shaft 50.

[0039] See Figure 4 In some embodiments, the first end 320 of the cover plate 30 is rotatably connected to the wearing bracket 10, and the first end 320 and the protective cover 60 are integrally formed by the sleeve, so as to prevent the user from losing the cover plate 30 when cleaning hair or foreign objects in the fan 20.

[0040] Furthermore, the wearable bracket 10 also includes, for example, a temperature regulating component 70, a battery, and a circuit board. The temperature regulating component 70 and the battery are electrically connected to the circuit board to provide power for the operation of the temperature regulating component 70. The temperature regulating component 70 includes a cooling element 710, a cooling conductive element 720, and a heat dissipation element 730. The cooling element 710 includes a cold end and a hot end. The cooling conductive element 720 is thermally connected to the cold end, and the heat dissipation element 730 is thermally connected to the hot end. The wearable bracket 10 is provided with heat dissipation holes corresponding to the heat dissipation element 730, and the heat dissipation holes include, for example, a plurality of holes. External airflow enters through the second air inlet 410 and the first air inlet 110. The fan 20 rotates to direct the airflow towards the temperature control component 70, activating the cooling element 710. The cooling conductor 720 conducts the cooling energy from the cold end of the cooling element 710 to cool the human body, improving the user's perceived temperature. This allows the user to cool down using both the fan 20 and the temperature control component 70, enhancing user convenience. The airflow from the fan 20 passes through the heat sink 730 to remove heat from the hot end of the cooling element 710. The heat sink 730 increases the heat exchange area between the airflow from the fan 20 and the hot end, thereby improving heat dissipation efficiency. For example, the heat dissipation holes are located on the outer side plate of the wearing bracket 10 away from the human body, with the exhaust direction facing away from the body. The cooling conductor 720 is positioned, for example, towards the wearing space 160. When the user uses the neck fan, the cooling conductor 720 comes into contact with the skin, achieving cooling.
