Description

Technical Field

[0001] This utility model relates to the field of portable fan technology, and in particular to a neck-hanging fan. Background Technology

[0002] With the improvement of living standards, various portable temperature-controlled products, such as neck fans, have emerged on the market to meet the needs of outdoor activities and other life scenarios. Neck fans effectively solve the limitations of handheld fans, freeing up users' hands for use in outdoor sports or office settings.

[0003] Existing neck fans typically require an internal air guide component to direct the airflow from the fan to the outlet. However, these existing air guide components are usually a single, thin plate that is prone to deformation. Improper handling during assembly can cause the air guide component to deform, affecting the assembly effect or even causing damage. Utility Model Content

[0004] In view of this, the present invention provides a neck fan to solve the problem that the air guide component is easily deformed in the prior art.

[0005] This application provides a neck fan, including a wearing bracket and a fan disposed in the wearing bracket. An air duct is formed in the wearing bracket, and the fan is located in the air duct. The wearing bracket is provided with an air inlet and an air outlet respectively connected to the air duct.

[0006] The air duct is provided with an air guide assembly extending from the air outlet side of the fan toward the air outlet. The air guide assembly includes a first air guide plate and a second air guide plate. The first air guide plate is disposed near the air outlet side of the fan relative to the second air guide plate. The second air guide plate extends from the end of the first air guide plate away from the air outlet side of the fan to the air outlet.

[0007] In some embodiments, the first air guide plate and the second air guide plate are spliced ​​together to form a curved structure or a straight structure.

[0008] In some embodiments, the second air guide plate includes two fixing parts that are fixedly connected to the wearing bracket, the two fixing parts being spaced apart from each other and located on opposite sides of the air outlet.

[0009] In some embodiments, the wearing bracket further includes a flow guide, which cooperates with the wearing bracket to form an air duct. The second air guide plate is provided with an extension, and the flow guide is provided with a positioning hole, into which the extension is inserted.

[0010] In some embodiments, the air duct includes a main air duct and a plurality of sub-air ducts, each of the sub-air ducts being connected at both ends to the main air duct and the air outlet, respectively. The air guiding components include a plurality of components, which are spaced apart to form the plurality of sub-air ducts.

[0011] In some embodiments, the plurality of air guiding components form an angle of less than 90° with the side of the wearing bracket where the air outlet is located, and the angle gradually decreases in the direction away from the fan.

[0012] In some embodiments, the minimum distance between the air guide assembly near the fan and the fan is one-fifteenth to one-fifth of the fan diameter.

[0013] In some embodiments, the spacing between adjacent air guide components gradually increases in the direction away from the fan.

[0014] In some embodiments, the wearing bracket further includes a guide member, which cooperates with the wearing bracket to form an air duct. The guide member has a side wall on the side away from the air outlet. The side wall is spaced apart from the air guide assembly. The minimum distance between the plurality of air guide assemblies and the side wall gradually decreases in the direction away from the fan.

[0015] In some embodiments, the neck fan further includes a battery and a battery fireproof compartment, the battery fireproof compartment being located within the wearing bracket, and the battery being located within the battery fireproof compartment and electrically connected to the fan; and / or,

[0016] The neck fan also includes a battery located within the wearing bracket and a charging interface electrically connected to the battery. The battery is electrically connected to the fan. The wearing bracket has a clearance hole corresponding to the charging interface, and an annular fireproof component surrounding the charging interface is provided in the clearance hole.

[0017] The neck fan provided by this utility model sets the air guide assembly into two parts: a first air guide plate and a second air guide plate. The first air guide plate and the second air guide plate are shorter than the overall length of the air guide assembly. Therefore, with the same thickness, it is more difficult for the first air guide plate and the second air guide plate to deform, which can reduce the risk of deformation or even damage to the air guide assembly during assembly.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0030] Please see Figures 1 to 8 This utility model provides a neck fan 10, which is worn around a user's neck to blow airflow toward the user's neck or head, thereby creating a cooling effect.

[0031] The neck fan 10 includes a wearing bracket 12, a fan 14, and an air guide 16. The fan 14 and the air guide 16 are respectively installed inside the wearing bracket 12, which forms an air duct 18. Optionally, the air guide 16 cooperates with the wearing bracket 12 to form the air duct 18. The fan 14 is located inside the air duct 18. The wearing bracket 12 is provided with an air inlet 20 and an air outlet 22, which are respectively connected to the air duct 18. When the fan 14 is working, it can drive the air outside the neck fan 10 to enter the air duct 18 through the air inlet 20, flow in the air duct 18, and finally be discharged from the air outlet 22, blowing towards the user to create a cooling effect.

[0032] Specifically, the wearing bracket 12 forms a wearing space 24, through which the neck fan 10 can be worn on the neck for use.

[0033] The support 12 is preferably made of a flexible material such as silicone to ensure wearing comfort.

[0034] The wearing bracket 12 includes a neckband 26 and two handles 28. The two handles 28 are connected to both ends of the neckband 26, with the ends of the two handles 28 away from the neckband 26 spaced apart, forming a U-shaped or C-shaped structure. The two neckbands 26 and the handles 28 together form a wearing space 24. Each handle 28 contains a fan 14 and an airflow guide 16. Specifically, the two handles 28 are symmetrically arranged on opposite sides of the neckband 26. During use, the user can grasp the two handles 28 with both hands and then wear the neck fan 10 around the neck through the wearing space 24. In the wearing state, the neckband 26 is located at the back of the neck, and the two handles 28 are located on the left and right sides of the neck, respectively.

[0035] Preferably, the neckband 26 has a certain degree of elasticity and can deform, so that the ends of the two handles 28 away from the neckband 26 can move closer to each other or further apart, thereby adjusting the size of the wearing space 24, making it convenient for users to wear or remove the fan, and also allowing the neckband fan 10 to be adapted to users of different body types.

[0036] The specific positions of the air inlet 20 and air outlet 22 on the neck support 12 are not limited, as long as the air inlet 20 and air outlet 22 are not completely blocked during use, and the air blown from the air outlet 22 can blow towards the user. Preferably, the air inlet 20 and air outlet 22 are located on different sides of the neck support 12 to avoid mutual interference between the air inlet and outlet, which would affect the air intake and air output.

[0037] In this embodiment, the air outlet 22 is located on one side of the wearing bracket 12 in the height direction. The height direction refers to the height direction of the human body when the wearing bracket 12 is worn around the neck. This allows the airflow to blow directly towards the user when it is blown out of the air outlet 22 by the fan 14, while also preventing the air outlet 22 from being blocked by the skin. Specifically, the wearing bracket 12 has an open annular structure, forming an open annular wearing space 24. The height direction of the wearing bracket 12 is also the axial direction of the wearing space 24.

[0038] The air outlet 22 extends circumferentially along the wearing bracket 12 and forms a long and narrow air outlet 22 to increase the air pressure when the airflow is blown out of the air outlet 22, thereby improving the user's airflow experience.

[0039] An air inlet 20 is located at the end of the handle 28 away from the neck strap 26, and the air inlet 20 is provided on both the side of the handle 28 closest to the wearing space 24 and the side furthest from the wearing space 24. The air inlet 20 and the air outlet 22 are located on different sides of the handle 28, so that the air intake and exhaust directions are different, preventing mutual interference between the air intake and exhaust. Furthermore, placing the air inlet 20 at the end of the handle 28 away from the neck strap 26 avoids the air inlet 20 being blocked by the skin. Specifically, a fan 14 is located at the end of the handle 28 away from the neck strap 26, and the fan 14 is positioned between the two air inlets 20 to increase the air intake volume.

[0040] In one embodiment, the air duct 18 is provided with an air guide assembly 30 extending from the air outlet side of the fan 14 toward the air outlet 22 to guide the airflow in the air duct 18 toward the air outlet 22. The air guide assembly 30 includes a first air guide plate 32 and a second air guide plate 34. The first air guide plate 32 and the second air guide plate 34 are separately formed. The first air guide plate 32 is disposed opposite the second air guide plate 34 near the air outlet side of the fan 14. The second air guide plate 34 extends from the end of the first air guide plate 32 away from the air outlet side of the fan 14 to the air outlet 22.

[0041] In an optional example, the first air guide plate 32 is disposed on the air guide member 16, and the second air guide plate 34 is disposed on the wearing bracket 12. The first air guide plate 32 is fixed to the air guide member 16, and the second air guide plate 34 is fixed to the wearing bracket 12. The first air guide assembly 30 and the second air guide assembly 30 are both located in the air duct 18, and one of the first air guide plate 32 and the second air guide plate 34 extends from one end of the other to the air outlet 22. That is, the first air guide plate 32 extends from one end of the second air guide plate 34 to the air outlet 22, or the second air guide plate 34 extends from one end of the first air guide plate 32 to the air outlet 22. The first air guide plate 32 and the second air guide plate 34 cooperate to guide the airflow towards the air outlet, thereby achieving the effect of guiding the airflow. By configuring the air guide assembly 30 as a first air guide plate 32 and a second air guide plate 34, the first air guide plate 32 and the second air guide plate 34 are smaller in length than the overall length of the air guide assembly 30. Therefore, with the same thickness, the first air guide plate 32 and the second air guide plate 34 are more difficult to deform, which can reduce the risk of deformation or even damage to the air guide assembly 30 during assembly. Moreover, the first air guide plate 32 and the second air guide plate 34 are respectively set on the air guide 16 and the wearing bracket 12, so the first air guide plate 32 and the second air guide plate 34 will not interfere with each other during the processing and forming process, reducing the production difficulty.

[0042] Preferably, the second air guide plate 34 extends from one end of the first air guide plate 32 to the air outlet 22, and the end of the second air guide plate 34 away from the first air guide plate 32 is connected to the side of the wearing bracket 12 where the air outlet 22 is located. Since the second air guide plate 34 is mounted on the wearing bracket 12, it is only necessary to fix one end of the second air guide plate 34 to the side of the wearing bracket 12 where the air outlet 22 is located. This allows the second air guide plate 34 to automatically extend towards the air outlet 22 while the assembly of the second air guide plate 34 is completed, thereby reducing the difficulty of assembly.

[0043] Specifically, the first air guide plate 32 is integrally formed with the air guide component 16, and the second air guide plate 34 is integrally formed with the wearing bracket 12, which ensures the connection strength while eliminating the assembly process.

[0044] Understandably, the first air guide plate 32 and the second air guide plate 34 can be attached together on adjacent sides, or there can be a small gap between the first air guide plate 32 and the second air guide plate 34.

[0045] In one embodiment, the second air guide plate 34 extends from one end of the first air guide plate 32 to the air outlet 22 and is fixedly connected to the wearing bracket 12. The second air guide plate 34 includes two fixing parts 35 that are respectively fixedly connected to the wearing bracket 12. The two fixing parts 35 are spaced apart from each other, and the air outlet 22 is located between the two fixing parts 35. That is, the two fixing parts 35 are respectively on opposite sides of the air outlet 22. The second air guide plate 34 can provide support for the wearing bracket 12, enhance the overall strength of the wearing bracket 12 at the air outlet 22, and reduce the impact of the air outlet 22 on the strength of the wearing bracket 12. Thus, the second air guide plate 34 not only has the effect of guiding airflow but also enhances the strength of the wearing bracket 12.

[0046] In one embodiment, the second air guide plate 34 is provided with an extension 36, and the air guide member 16 is provided with a positioning hole 38. The extension 36 is inserted into the positioning hole 38, thereby aligning the second air guide plate 34 with the first air guide plate 32 to guide the airflow from the first air guide plate 32 to the second air guide plate 34. The cooperation between the extension 36 and the positioning hole 38 can play a positioning role during the assembly process, quickly finding the correct installation position of the second air guide plate 34 and reducing the assembly difficulty.

[0047] The specific shapes of the extension 36 and the positioning hole 38 are not limited. In this embodiment, the extension 36 is disposed on the second air guide plate 34. The second air guide plate 34 is plate-shaped, and the extension 36 is also plate-shaped to reduce the processing difficulty. The positioning hole 38 is a square hole for the extension 36 to be inserted.

[0048] Specifically, the size of the extension 36 gradually decreases in the direction away from the second air guide plate 34. That is, the end of the extension 36 connected to the second air guide plate 34 has the largest size, and the end away from the second air guide plate 34 has the smallest size. During the process of inserting the extension 36 into the positioning hole 38, the end of the extension 36 away from the second air guide plate 34 is inserted into the positioning hole 38 first. Since the end of the extension 36 away from the second air guide plate 34 has the smallest size, it is easier to insert into the positioning hole 38, reducing the positioning difficulty.

[0049] The handle portion 28 includes a first housing and a second housing that overlap each other. A guide member 16 is located between the first and second housings, and the guide member 16 cooperates with the first housing to form an air duct 18. A first air guide plate 32 is located on the side of the guide member 16 closest to the first housing, and a second air guide plate 34 is located on the inner side of the second housing. During assembly, the guide member 16 can be first installed onto the second housing. Then, the extension 36 is aligned with the positioning hole 38 and inserted into the positioning hole 38, aligning the second air guide plate 34 with the first air guide plate 32 to form the air guide assembly 30. Finally, the first and second housings are fixed together to complete the assembly.

[0050] In one embodiment, the first air guide plate 32 and the second air guide plate 34 are spliced ​​to form a curved structure or a straight structure, so that the extension trajectory of the first air guide plate 32 and the extension trajectory of the second air guide plate 34 are on the same trajectory, thereby reducing the wind resistance when the airflow moves from the first air guide plate 32 to the second air guide plate 34, and making the airflow smoother when passing the position that the first air guide plate 32 and the second air guide plate 34 want to approach.

[0051] Understandably, the extension trajectories of the first air guide plate 32 and the second air guide plate 34 can be straight lines or curved lines. That is, the first air guide plate 32 and the second air guide plate 34 can each be straight and spliced ​​together to form a straight sheet structure, or the first air guide plate 32 and the second air guide plate 34 can each be curved and spliced ​​together to form a curved sheet structure. In this embodiment, the first air guide plate 32 and the second air guide plate 34 are curved, and the extension trajectories of the first air guide plate 32 and the second air guide plate 34 are located on the same curved trajectory.

[0052] In one embodiment, there are multiple air guide components 30, and each air guide component 30 includes a first air guide plate 32 and a second air guide plate 34.

[0053] The air duct 18 includes a main air duct 40 and multiple sub-air ducts 42. The main air duct 40 and the sub-air ducts 42 extend in different directions, and each sub-air duct 42 is connected to both ends of the main air duct 40 and the air outlet 22, respectively. Multiple air guide components 30 are spaced apart to form multiple sub-air ducts 42. Optionally, multiple air guide components 30 are arranged at intervals along the extension direction of the main air duct 40 to form multiple sub-air ducts 42 arranged along the extension direction of the main air duct 40. A sub-air duct 42 is also formed between the fan 14 and an adjacent air guide component 30. Under the action of the fan 14, the outside air enters the wearing bracket 12 through the air inlet 20 and flows along the extension direction of the main air duct 40. When the airflow passes through a sub-air duct 42, some airflow flows from the main air duct 40 to that sub-air duct 42 and is finally discharged from the air outlet 22 connected to that sub-air duct 42, which has a diversion effect, allowing the airflow of the fan 14 to cover a wider area.

[0054] The specific number of air outlets 22 is not limited; there can be one or more. When there is only one air outlet 22, multiple sub-air ducts 42 are connected to different parts of the same air outlet 22. When there are multiple air outlets 22, each sub-air duct 42 can be connected to a corresponding air outlet 22.

[0055] Multiple air guide components 30 form an angle of less than 90° with the side of the wearing bracket 12 where the air outlet 22 is located. The angle gradually decreases in the direction away from the fan 14. That is, the tilt of the air guide components 30 relative to the air outlet 22 gradually decreases, and the air guide components 30 provide less air resistance during the airflow process. As the airflow travels further, the pushing effect of the fan 14 on the airflow gradually weakens, and the airflow velocity gradually decreases. Since the air guide components 30 provide less air resistance in the direction away from the fan 14, the airflow that is farther away from the fan 14 and has a slower flow velocity experiences less air resistance when flowing in the sub-air duct 42, thereby increasing the airflow volume.

[0056] The specific number of air guide components 30 is not limited, for example, two, three or more. This application takes three air guide components 30 in the air duct 18 as an example. Among the three air guide components 30, the angle α between the air guide component 30 closer to the fan 14 and the wearing bracket 12 is between 50° and 60°, the angle β between the air guide component 30 in the middle and the wearing bracket 12 is between 40° and 50°, and the angle γ between the air guide component 30 farther from the fan 14 and the wearing bracket 12 is between 30° and 40°.

[0057] The minimum distance between the air guide assembly 30 near the fan 14 and the fan 14 is one-fifteenth to one-fifth of the diameter of the fan 14. Since the sub-duct 42 between the fan 14 and the air guide assembly 30 is closest to the fan 14, the airflow velocity and volume are relatively high, making it more prone to turbulence and increased noise. Controlling the distance between the air guide assembly 30 and the fan 14 to one-fifth to one-fifth of the diameter of the fan 14, and keeping the sub-duct 42 closest to the fan 14 within a certain size range, reduces turbulence and noise, while also increasing airflow. Optionally, the minimum distance between the air guide assembly 30 near the fan 14 and the fan 14 is one-eighth to one-fifth of the diameter of the fan 14, where the diameter of the fan 14 is 35mm.

[0058] The spacing between adjacent air guide components 30 gradually increases in the direction away from the fan 14. That is, the air inlet 20 of the sub-duct 42 gradually increases, which increases the air intake volume. The air velocity and flow rate gradually decrease in the direction away from the fan 14, while the air inlet 20 of the sub-duct 42 gradually increases in the direction away from the fan 14. That is, a relatively small air inlet 20 is formed in the area with relatively high velocity and flow rate, and a relatively large air inlet 20 is formed in the area with relatively low velocity and flow rate, which is beneficial to balancing the air intake volume of each sub-duct 42.

[0059] The air guide 16 has a sidewall 44 on the side away from the air outlet 22. The sidewall 44 is spaced apart from the air guide assembly 30, and the distance between the multiple air guide assemblies 30 and the sidewall 44 gradually decreases in the direction away from the fan 14. The airflow velocity is inversely proportional to the distance between the air guide assembly 30 and the sidewall 44. When the airflow passes between the air guide assembly 30 and the sidewall 44, the smaller distance allows the airflow velocity to increase. The gradual decrease in the distance between the air guide assembly 30 and the sidewall 44 in the direction away from the fan 14 allows the airflow to travel a longer distance, thereby increasing the coverage area of ​​the neck fan 10.

[0060] Preferably, the side wall 44, the first air guide plate 32, and the air guide component 16 are integrally formed.

[0061] The sidewall 44 extends at least partially away from the fan 14 and toward the air outlet 22 at an angle, thereby causing the size of the main air duct 40 located thereto gradually decreases away from the fan 14, so as to increase the airflow velocity in the main air duct 40, and also facilitate the formation of a gradually decreasing gap between the air guide assembly 30 and the sidewall 44 away from the fan 14.

[0062] In one embodiment, the neck fan 10 also includes a battery and a battery fireproof compartment 46. The battery is electrically connected to the fan 14 to provide the power required for the fan 14 to operate. The battery fireproof compartment 46 is made of fireproof material and has a fireproof effect. The battery is stored in the battery fireproof compartment 46, which can reduce the risk of the battery spontaneously combusting and igniting other components in the wearing bracket 12, thereby reducing safety hazards.

[0063] The battery is a rechargeable battery for repeated use. The neck fan 10 also includes a charging port 48, which is electrically connected to the battery to charge it when the battery is low.

[0064] The wearable bracket 12 has a clearance hole corresponding to the charging interface 48. An annular fire-resistant element 52, made of fire-resistant material, surrounds the charging interface 48 within the clearance hole and provides fire protection. When charging the battery, the charger plug can be passed through the clearance hole 50 and plugged into the charging interface 48. The annular fire-resistant element 52 surrounds the charger plug, reducing the risk of the plug catching fire and igniting the wearable bracket 12, further minimizing safety hazards. Moreover, compared to making the entire wearable bracket 12 from fire-resistant material, this reduces production costs.

[0065] Specifically, the wearable bracket 12 contains a control circuit board, and the charging port and the battery are electrically connected to the control circuit board, thereby realizing the electrical connection between the charging port and the battery.

[0066] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
