Description

Technical Field

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

[0002] A neck fan is a wearable air-blowing device that moves with the user and frees their hands. It cools and dissipates heat by blowing air onto the face and neck.

[0003] Current neck fans typically consist of a housing and two fans. The housing contains an air duct, and the two fans are located at opposite ends of the housing to drive external airflow into the air duct. However, the two airflows interfere with each other when flowing in the air duct, affecting the air volume and causing uneven airflow, resulting in a poor user experience. Utility Model Content

[0004] The main purpose of this invention is to propose a neck-hanging fan, which aims to increase the air volume of the neck-hanging fan.

[0005] To achieve the above objectives, the present invention provides a neck fan comprising:

[0006] The housing includes a connecting part and two mounting parts disposed at both ends of the connecting part. The two mounting parts are disposed opposite to each other. Each mounting part is provided with an air duct. Each mounting part is also provided with a plurality of first air outlets and air inlets communicating with the air duct. The plurality of first air outlets are distributed at intervals along the extension direction of the air duct.

[0007] A fan is rotatably installed inside the air duct. The fan is used to drive external airflow into the air duct through the air inlet and then out through the plurality of first air outlets.

[0008] Optionally, the mounting part is further provided with a second air outlet, which is connected to the air duct and is located at the end of the mounting part away from the connecting part.

[0009] Optionally, the first air outlet is a long strip extending along the length of the air duct.

[0010] Optionally, the fan is located at the end of the air duct away from the connection, and the size of the air duct gradually decreases in the direction away from the fan.

[0011] Optionally, the mounting section further includes a mounting cavity, and the neck fan also includes a circuit assembly installed in the mounting cavity. The mounting cavity and the air duct are separated by a partition, and the partition has ventilation holes that connect the air duct and the mounting cavity.

[0012] Optionally, the neck fan also includes a display screen, which is located on the outer side of the mounting portion and electrically connected to the circuit assembly.

[0013] Optionally, the neck fan further includes a power module, the power module and the circuit components are respectively disposed in the mounting cavities of the two mounting parts, the power module is electrically connected to the circuit components and the fan, and the connecting part is provided with a connecting channel, the connecting channel communicating with the mounting cavity.

[0014] Optionally, the neck fan further includes a roller, which is rotatably mounted on the mounting portion and is used to adjust the power of the fan.

[0015] Optionally, the outer circumferential surface of the roller is provided with an anti-slip portion.

[0016] Optionally, the display screen and the roller are located on the same side of the mounting portion.

[0017] This utility model's technical solution involves configuring the housing as a connecting part and two mounting parts located at both ends of the connecting part, with the two mounting parts arranged opposite each other. Each mounting part contains an air duct and multiple first air outlets and air inlets communicating with the air duct. The multiple first air outlets are spaced apart along the extension direction of the air duct. A fan is rotatably mounted within the air duct to drive external airflow into the air duct through the air inlets and out through the multiple first air outlets. This creates an air duct within the mounting part, and the connecting part separates the two mounting parts, preventing the airflow from the two fans from interfering with each other. This improves the airflow volume of the neck fan and makes the airflow from each first air outlet more uniform. Simultaneously, it shortens the length of the air duct, reducing the possibility of airflow attenuation due to a long airflow path, thus ensuring a stronger airflow from the first air outlets.

[0031] This utility model proposes a neck-hanging fan.

[0032] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the neck fan includes a housing 10 and a fan 20.

[0033] Specifically, the housing 10 includes a connecting portion 11 and two mounting portions 12 disposed at both ends of the connecting portion 11. The two mounting portions 12 are disposed opposite to each other. Each mounting portion 12 has an air duct 124. The mounting portion 12 also has a plurality of first air outlets 121 and air inlets 123 communicating with the air ducts 124. The plurality of first air outlets 121 are spaced apart along the extension direction of the air ducts 124. The number of first air outlets 121 is at least two. For example, the number of first air outlets 121 can be, but is not limited to, two, three, four, etc. Optionally, the first air outlets 121 are elongated strips extending along the length direction of the air ducts 124.

[0034] The fan 20 is rotatably installed within the air duct 124. The fan 20 drives external airflow into the air duct 124 through the air inlet 123 and then out through multiple first air outlets 121. In other words, the fan 20 drives external airflow into the air duct 124 through the air inlet 123 and then blows it out through the multiple first air outlets 121, allowing the user to receive airflow from the multiple first air outlets 121 when wearing the neck fan. In this embodiment, the neck fan also includes a control switch 60, which is connected to the fan 20 and used to control the fan 20 to turn on and off.

[0035] In practical use, the user wears the neck fan around their neck, and the fan 20 drives the airflow from the air inlet 123 into the air duct 124 and blows it out from the multiple first air outlets 121, so that the user can receive the airflow blown out by the multiple first air outlets 121.

[0036] This utility model's technical solution involves configuring the housing 10 as a connecting part 11 and two mounting parts 12 located at both ends of the connecting part 11. The two mounting parts 12 are arranged opposite to each other. Each mounting part 12 has an air duct 124 and multiple first air outlets 121 and air inlets 123 communicating with the air duct 124. The multiple first air outlets 121 are spaced apart along the extension direction of the air duct 124. A fan 20 is rotatably mounted inside the air duct 124 to drive external airflow into the air duct 124 through the air inlets 123 and out through the multiple first air outlets 121. In this way, an air duct 124 is formed within the mounting part 12. The connecting part 11 separates the two mounting parts 12, preventing the airflow blown by the two fans 20 from interfering with each other. This helps to increase the air volume of the neck fan and makes the airflow from each first air outlet 121 more uniform. At the same time, it can shorten the length of the air duct 124, which can reduce the airflow attenuation caused by the long airflow path, so that the airflow blown out from the first air outlet 121 is stronger.

[0037] In some embodiments, the mounting portion 12 is further provided with a second air outlet 122, which communicates with the air duct 124 and is located at the end of the mounting portion 12 away from the connecting portion 11. Specifically, the fan 20 drives airflow from a plurality of first air outlets 121 and second air outlets 122, which helps to increase the air volume of the neck fan. Of course, in other embodiments, the mounting portion 12 does not have a third air outlet.

[0038] In some embodiments, the fan 20 is located at the end of the air duct 124 away from the connecting portion 11, and the size of the air duct 124 gradually decreases in the direction away from the fan 20. It is known that, without changing the motor speed, the size of the air duct 124 can affect the airflow velocity. By gradually decreasing the size of the air duct 124, after the fan 20 drives the airflow into the air duct 124, the gradually decreasing air duct 124 can increase the airflow velocity, making the airflow blown from the first air outlet 121 and the second air outlet 122 stronger, thereby improving the cooling effect of the neck fan and enhancing the user experience. Of course, in other embodiments, the dimensions at both ends of the air duct 124 are the same.

[0039] In some embodiments, the mounting part 12 is further provided with a mounting cavity 125, and the neck fan also includes a circuit assembly, which is installed in the mounting cavity 125. The mounting cavity 125 and the air duct 124 are separated by a partition 30, which is provided with a ventilation hole, and the ventilation hole connects the air duct 124 and the mounting cavity 125.

[0040] Specifically, when the neck fan is in use, the circuit components generate heat. By providing ventilation holes in the partition 30, the airflow blown by the fan 20 can exchange heat with the circuit components within the airflow mounting cavity 125. After the heat exchange is complete, the airflow is discharged through the ventilation holes, thus achieving heat dissipation for the circuit components. This design not only achieves heat dissipation for the circuit components but also does not affect the airflow volume. Of course, in other embodiments, the partition 30 does not have ventilation holes.

[0041] In some embodiments, the neck fan further includes a display screen 50, which is disposed on the outer side of the mounting portion 12 and electrically connected to the circuit components. Specifically, the display screen 50 can be used to display the power level of the power module 70, so that the user can clearly know the power level of the power module 70. The display screen 50 can also be used to display the speed setting of the fan 20. For example, the display screen 50 can display low, medium, and high speeds according to the fan speed setting, and can also be set to display level 1, level 2, level 3, etc. The specific settings can be configured according to the actual situation. In other embodiments, the neck fan is equipped with indicator lights, which are electrically connected to the circuit components and exposed on the surface of the mounting portion 12 to provide prompts to the user.

[0042] In some embodiments, the neck fan further includes a power module 70. The power module 70 and the circuit components are respectively disposed in the mounting cavities 125 of the two mounting portions 12. The power module 70 is electrically connected to the circuit components and the fan 20. A connection channel is provided in the connection portion 11, and the connection channel communicates with the mounting cavity 125. Specifically, the circuit components are installed in the mounting cavity 125 of one mounting portion 12, and the power module 70 is installed in the mounting cavity 125 of the other mounting portion 12. A connection channel is provided in the connection portion 11 to connect the mounting cavities 125 of the two mounting portions 12. This arrangement facilitates the wiring between the power module 70 and the circuit components.

[0043] In some embodiments, the neck fan further includes a roller 40, which is rotatably mounted on the mounting portion 12. The roller 40 is used to adjust the power of the fan 20. Users can adjust the operating speed of the fan 20 by rolling the roller 40. We know that the adjustment method using the roller 40 is relatively simple, and its application in this solution improves the user experience. Of course, in other embodiments, the neck fan device is equipped with an adjustment knob, which can be used to adjust the speed of the fan 20.

[0044] In some embodiments, the outer peripheral surface of the roller 40 is provided with an anti-slip portion. Specifically, the anti-slip portion is used to increase the friction with the user's hand, preventing slippage when rolling the roller 40 and improving the smoothness of rolling. Optionally, the anti-slip portion can be configured as a protrusion on the outer peripheral surface of the roller 40; or it can be configured as a groove recessed on the outer peripheral surface of the roller 40.

[0045] In some embodiments, the display screen 50 and the roller 40 are located on the same side of the mounting portion 12. That is, when the user adjusts the speed of the fan 20 using the roller 40, they can clearly see the current operating speed of the fan 20 by checking the display screen 50, thus facilitating adjustment according to their needs. Simultaneously, placing the display screen 50 and the roller 40 on the same side avoids the hassle of wiring and improves the structural compactness of the neck fan. Of course, in other embodiments, the display screen 50 and the roller 40 are located on two separate mounting portions 12.

[0046] In some embodiments, the neck fan also includes multiple guide vanes, all of which are disposed in the air duct 124. The multiple guide vanes are spaced apart from each other, and a guide vane is provided between two adjacent second air outlets 122. The length of the multiple guide vanes gradually increases in the direction of airflow.

[0047] Specifically, the deflector is used to guide the airflow from the fan 20 to the second air outlet 122 on the front side, thereby increasing the air volume of the second air outlet 122 and thus improving the cooling effect of the neck fan. Of course, in other embodiments, the neck fan does not have a deflector.

[0048] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
