[0022] 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.

[0023] See Figure 1 , Figure 2 and Figure 4This utility model discloses a neck fan, including a wearing bracket 10. The wearing bracket 10 includes two interconnected wearing arms 150, which together form a wearing space 160. The two wearing arms 150 are connected by means such as hinges or fixed connections. An air outlet 110 is provided on the wearing bracket 10. The wearing bracket 10 includes a first housing 120, on which a first air inlet 410 is provided. A fan 20 is located inside the wearing bracket 10, and the fan 20 is, for example, a centrifugal fan or an axial fan. A first partition 310 is located inside the wearing bracket 10 and between the fan 20 and the first housing 120. A second air inlet 420 is provided on the first partition 310. A first air duct 510 is formed between the first partition 310 and the first housing 120, and the first air duct 510 communicates with the first air inlet 410 and the second air inlet 420. In particular, along the length of the support bracket 10, the second air inlet 420 and the first air inlet 410 are spaced apart so that the second air inlet 420 and the first air inlet 410 are staggered.

[0024] The wearing bracket 10 is the main support structure of the neck fan. Its shape and size are ergonomically designed for comfortable wear around the neck. The wearing bracket 10 includes an inner shell and an outer shell. The inner shell is located on the side closest to the wearing space 160, facing the neck when worn by the user. It can be made of skin-friendly materials, such as silicone or soft plastic, to improve wearing comfort and reduce neck discomfort. The outer shell protects the internal components and is typically made of sturdy plastic. The first housing 120 can be either the inner shell or the outer shell.

[0025] The first air inlet 410 is located on the first housing 120, and the second air inlet 420 is located on the first partition 310. When the fan 20 is working, the air enters the first air duct 510 through the first air inlet 410, then flows to the fan 20 through the second air inlet 420, and finally is blown out from the air outlet 110. By staggering the first air inlet 410 and the second air inlet 420, even if hair is sucked into the first air inlet 410, it is unlikely to get tangled in the fan 20 through the second air inlet 420 and become impossible to remove. This effectively avoids the problem of hair tangling and improves the safety and ease of use of this neck fan device.

[0026] The first partition 310 guides airflow and prevents the airflow entering from the first air inlet 410 from directly colliding with the air blown out by the fan 20, thereby avoiding airflow turbulence and noise. A first air duct 510 is formed between the first partition 310 and the first housing 120. The first air duct 510 is connected to the first air inlet 410 and the second air inlet 420, ensuring that the airflow entering the support bracket 10 from the first air inlet 410 can smoothly enter the fan 20 and be blown out, thus ensuring airflow efficiency.

[0027] The air outlet 110 is used to direct the air blown out by the fan 20. The shape and position of the air outlet 110 are optimized according to the design of the wearing bracket 10 to ensure that the airflow can be evenly directed to the user's body parts, such as the neck and face.

[0028] The edge of the first air inlet 410 is provided with a dust filter, which can block large particles of foreign matter and prevent hair from being torn by high-speed airflow.

[0029] Neck-mounted fans typically include a power module and a control module. The power module can use a rechargeable battery, such as a lithium battery, which can be charged via a USB interface for user convenience. The control module includes a power switch and speed control buttons, allowing users to control the fan's on / off state and fan speed to meet their needs in different scenarios.

[0030] The device includes multiple air outlets 110, which are arranged at intervals along the length of the support bracket 10 to provide a wider airflow range and ensure even airflow. The air outlets 110 can be circular, elliptical, or strip-shaped.

[0031] See Figure 2 In some embodiments, the first partition 310 has a first end 311 and a second end 312 opposite to each other; a first air inlet 410 is provided corresponding to the first end 311, and a second air inlet 420 is opened on the second end 312; a first air duct 510 extends along the first end 311 of the first partition 310 toward the second end 312. By respectively providing the first air inlet 410 and the second air inlet 420 at both ends of the first partition 310, the difficulty of hair entering through the first air inlet 410 and then tangling around the fan 20 through the second air inlet 420 is further increased, improving safety during use.

[0032] See Figure 2 and Figure 3 In some embodiments, the fan 20 is positioned near the second end 312 of the first partition 310 and corresponds to the second air inlet 420. This ensures that the airflow enters the first air duct 510 from the first air inlet 410 and then flows to the second air inlet 420, so that it can enter the fan 20 efficiently and smoothly. This reduces the path and energy loss of the airflow before entering the fan 20 and improves the air circulation efficiency. It also prevents the airflow from entering the fan 20 from the second air inlet 420 from colliding with the airflow from the fan 20, thus avoiding airflow turbulence and noise.

[0033] See Figure 2 and Figure 4In some embodiments, the neck fan of this device further ensures the air intake of the fan 20. The neck fan also includes a second partition 320, and the wearing bracket 10 also includes a second housing 130 opposite to the first housing 120. The second partition 320 is located between the fan 20 and the second housing 130, and the fan 20 is located between the first partition 310 and the second partition 320. A third air inlet 430 is provided on the second housing 130, and a fourth air inlet 440 is provided on the second partition 320. In the length direction of the wearing bracket 10, the fourth air inlet 440 and the third air inlet 430 are spaced apart so that the fourth air inlet 440 and the third air inlet 430 are staggered. A second air duct 520 is formed between the second partition 320 and the second housing 130, and the second air duct 520 is connected to the third air inlet 430 and the fourth air inlet 440.

[0034] Specifically, a second partition 320 is provided between the fan 20 and the second housing 130, forming an independent second air duct 520 between the second partition 320 and the second housing 130. The second air duct 520 and the first air duct 510 are independent of each other, ensuring that external airflow can efficiently enter the fan 20. The first partition 310 and the second partition 320 are respectively provided with a second air inlet 420 and a fourth air inlet 440. The fan 20 can achieve air intake from two directions through the second air inlet 420 and the fourth air inlet 440, which significantly increases the air intake volume of the fan 20 and improves the air volume output efficiency.

[0035] The wearing bracket 10 includes a first housing 120 and a second housing 130, which are arranged opposite to each other to form the main structure of the neck fan. The first housing 120 can be either an inner housing or an outer housing, and the second housing 130 can be either an inner housing or an outer housing.

[0036] The third air inlet 430 is located on the second housing 130, and the fourth air inlet 440 is located on the second partition 320. The third air inlet 430 and the fourth air inlet 440 are staggered. Even if hair is sucked in through the third air inlet 430, it is difficult for it to get tangled on the fan through the fourth air inlet 440 and be unable to be pulled out. This effectively avoids the problem of hair tangling and improves the safety and ease of use of this neck fan device.

[0037] The second partition 320 also guides airflow, preventing the airflow entering from the third air inlet 430 from directly colliding with the air blown out by the fan 20, thereby avoiding airflow turbulence and noise. A second air duct 520 is formed between the second partition 320 and the first housing 120. The second air duct 520 is connected to the third air inlet 430 and the fourth air inlet 440, ensuring that the airflow entering the support bracket 10 from the third air inlet 430 can smoothly enter the fan 20 and be blown out, ensuring airflow efficiency.

[0038] See Figure 2 and Figure 4 In some embodiments, the second partition 320 has a third end 321 and a fourth end 322, with the fourth end 322 corresponding to the second end 312. The third air inlet 430 is corresponding to the third end 321, and the fourth air inlet 440 is located on the fourth end 322. The second air duct 520 extends from the third end 321 of the second partition 320 toward the fourth end 322. The third air inlet 430 and the fourth air inlet 440 are respectively located at the two ends of the second partition 320, which further increases the difficulty for hair to enter through the third air inlet 430 and then entangle around the fan 20 through the fourth air inlet 440, thus improving safety. The fourth air inlet 440 corresponds to the fan 20, ensuring that the airflow enters the second air duct 520 from the third air inlet 430 and then flows to the fourth air inlet 440, so that it can enter the fan 20 efficiently and smoothly. This reduces the path and energy loss of the airflow before entering the fan 20 and improves the air circulation efficiency. It also prevents the airflow from entering the fan 20 from the fourth air inlet 440 from colliding with the airflow from the fan 20, thus avoiding airflow turbulence and noise.

[0039] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the edges of the first partition 310 and the second partition 320 extend along the inner wall of the wearing bracket 10 to abut against the inner wall of the wearing bracket 10. Specifically, the surfaces of the first partition 310 and the second partition 320 extend along the length and width directions of the wearing bracket 10 to abut against the inner wall of the wearing bracket 10. The abutment of the first partition 310 and the second partition 320 against the inner wall of the wearing bracket 10 further ensures the sealing between the first partition 310 and the second partition 320 and the wearing bracket 10, ensuring the independence between the first air duct 510 and the second air duct 520, allowing airflow to efficiently enter the fan 20 through independent air ducts, avoiding turbulence and collisions when airflow enters the fan 20. The first partition 310 and the second partition 320 are connected to the wearing bracket 10, for example, by bolts or adhesive.

[0040] See Figure 2In some embodiments, the second housing 130 is located on the side closer to the wearing space 160. The second housing 130 is the inner housing of the wearing bracket 10, and the first housing 120 is the outer housing of the wearing bracket 10. Since there is more hair on the outside and less hair on the inside of the neck fan during use, making the opening area of ​​the first air inlet 410 smaller than the opening area of ​​the third air inlet 430 reduces the probability of hair being sucked into the first air inlet 410, further improving the safety of the neck fan and reducing the risk of hair entanglement. Ensuring the opening area of ​​the third air inlet 430 ensures sufficient air intake to meet the operating requirements of the fan 20.

[0041] Furthermore, multiple first air inlets 410 are provided, and the multiple first air inlets 410 are distributed in a honeycomb array. The honeycomb air inlet design can effectively disperse the intake direction of airflow, reduce the risk of hair being inhaled, and ensure sufficient air intake. The shape of each first air inlet 410 is, for example, circular, hexagonal, or other polygonal.

[0042] Furthermore, the third air inlet 430 is a relatively large air inlet, such as a strip-shaped air inlet. When the user wears the neck fan, the third air inlet 430 is close to the user's neck. During the wearing and use process, there is less hair coming into contact with the third air inlet 430 on the inside. The third air inlet 430 ensures sufficient air intake and also reduces the risk of hair being sucked into the third air inlet 430.

[0043] See Figure 2 and Figure 3 In some embodiments, a guide plate 60 is provided on one of the first partition 310 and the second partition 320. The guide plate 60 is located between the first partition 310 and the second partition 320 and forms a third air duct 530 by separating the cavity between the first partition 310 and the second partition 320. The fan 20 is located in the third air duct 530. The wearing bracket 10 also includes a side wall 140 connecting the first housing 120 to the second housing 130. The side wall 140 has an air outlet 110 corresponding to the third air duct 530.

[0044] See Figure 2 and Figure 3In some embodiments, a guide plate 60 is provided on one of the first partition 310 and the second partition 320. The guide plate 60 is located between the first partition 310 and the second partition 320 and forms a third air duct 530 by separating the cavity between the first partition 310 and the second partition 320. The fan 20 is located in the third air duct 530. The wearing bracket 10 also includes a side wall 140 extending from the first housing 120 to the second housing 130. The side wall 140 is provided with an air outlet 110 corresponding to the third air duct 530. The guide plate 60 guides the air from the air outlet side of the fan to the air outlet 110 of the housing. The plate surface of the guide plate 60 extends along the length and thickness direction of the wearing bracket 10 and forms a third air duct 530 in the cavity between the first partition 310 and the second partition 320, which can effectively guide the airflow blown from the air outlet side of the fan 20 to the air outlet 110. The air guide plate 60 abuts between the first partition 310 and the second partition 320 to strengthen the overall structural strength. The air guide plate 60 may be formed by extending from one of the opposite ends of the first partition 310 or the second partition 320, or it may be assembled and fixed on the first partition 310 or the second partition 320.

[0045] See Figure 3 In some embodiments, to ensure that the airflow within the third air duct 530 flows evenly from the air outlet 110, a guide vane 70 is also provided within the third air duct 530. The guide vane 70 is curved, with one end facing the air outlet side of the fan 20 and the other end facing the air outlet 110. The air blown out from the fan 20 is further diverted by the guide vane 70, and the diverted airflow is blown out from the air outlets 110 on both sides of the baffle, balancing the airflow at different positions of the air outlets 110 within the corresponding third air duct 530, resulting in a more consistent airflow at each point of the air outlet 110, thus improving the user experience.

[0046] Furthermore, multiple air outlets 110 are provided, and the end of the guide vane 70 away from the fan 20 is located between any two adjacent air outlets 110, further uniformly distributing the airflow of the neck fan.

[0047] In some embodiments, each of the two wearing arms 150 is provided with a fan 20, a first partition 310 and a first housing 120 to increase the cooling efficiency of the neck fan.

[0048] Furthermore, the wearing bracket 10 includes, for example, a connecting frame 170 and two wearing arms 150 respectively installed at both ends of the connecting frame 170, with the connecting frame 170 and the two wearing arms 150 forming a wearing space 160; at least one wearing arm 150 is provided with a fan 20, a first partition 310, and a first housing 120. Preferably, for example, the fan 20, the first partition 310, and the first housing 120 can be provided in both wearing arms 150, thereby increasing the cooling efficiency of the neck fan. In one specific embodiment, the fan 20, the first partition 310, and the first housing 120 can also be provided in the connecting frame 170, for example; this application does not specifically limit this.
