[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 a fan. The housing contains an air duct, and the fan draws air from the outside into the duct and then exhausts it through the outlet to the user. However, current neck fans have a small airflow and poor cooling performance. Summary of the Invention

[0004] The main purpose of this invention is to propose a neck-hanging fan, which aims to improve the cooling and heat dissipation effect 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 portion and two mounting portions disposed at both ends of the connecting portion, the two mounting portions being arranged opposite each other. Each mounting portion has an air duct, and further includes a plurality of first air outlets, a plurality of second air outlets, and an air inlet communicating with the air duct. The first and second air outlets are spaced vertically apart. The plurality of first air outlets are spaced apart along the length of the air duct, and the plurality of second air outlets are arranged vertically and spaced apart along the length 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 a plurality of first air outlets and a plurality of second air outlets.

[0008] Optionally, the first air outlet is located on the top surface of the mounting portion, and the second air outlet is located below the first air outlet.

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

[0010] Optionally, the mounting part is further provided with a third air outlet, which is connected to a ventilation duct and is located at the end of the mounting part away from the connecting part.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] Optionally, the neck fan further includes a roller, which is rotatably mounted on the mounting part for adjusting 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 divides the housing into a connecting part and two mounting parts located at both ends of the connecting part. The two mounting parts are arranged opposite each other. An air duct is set within each mounting part, and multiple first air outlets, multiple second air outlets, and an air inlet are arranged within the air duct. The first and second air outlets are arranged vertically at intervals, with the first air outlets spaced apart along the length of the air duct. The air outlets are also arranged vertically and spaced apart along the length of the air duct. A fan is mounted inside the air duct and drives external airflow into the air duct through the air inlet and out through the multiple first and second air outlets.

[0030] This utility model proposes a neck-hanging fan.

[0031] In this embodiment of the utility model, as shown in Figures 1 to 5, the neck fan includes a housing 10 and a fan 20.

[0032] 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 arranged opposite to each other. Each mounting portion 12 has an air duct 124 and also has multiple first air outlets 121, multiple second air outlets 122, and an air inlet 126 communicating with the air duct 124. The first air outlets 121 and second air outlets 122 are arranged vertically at intervals. The multiple first air outlets 121 are distributed at intervals along the length of the air duct 124, and the multiple second air outlets 122 are arranged vertically at intervals along the length of the air duct 124, i.e., the multiple second air outlets 122 are arranged in a stepped manner, so that when the user uses the device, multiple positions on the user's neck can receive airflow from the second air outlets 122. The number of first air outlets 121 and second air outlets 122 is at least two. For example, the number of first air outlets 121 and second air outlets 122 can be, but is not limited to, two, three, four, etc. Optionally, the first air outlet 121 and the second air outlet 122 are arranged in the form of long strips extending along the length of the air duct 124.

[0033] The fan 20 is rotatably installed inside the air duct 124 to drive external airflow into the air duct 124 through the air inlet 126 and out through multiple first air outlets 121 and multiple second air outlets 122. In other words, the fan 20 drives airflow out through multiple first air outlets 121 and multiple second air outlets 122, so that when the user wears the neck fan, they can receive airflow from multiple first air outlets 121 and multiple second air outlets 122.

[0034] In this embodiment, the neck fan also includes a power module 70 and a control switch 80. The power module 70 is electrically connected to the fan 20 and is used to provide power to the fan 20. The control switch 80 is electrically connected to the fan 20 and is used to control the fan 20 to turn on and off.

[0035] In practical use, the user wears the neck fan around their neck. The fan 20 drives the airflow from the air inlet 126 into the air duct 124, and then blows it out from multiple first air outlets 121 and multiple second air outlets 122, so that the user can receive the airflow blown out by the multiple first air outlets 121 and multiple second air outlets 122.

[0036] The present invention divides the housing 10 into a connecting part 11 and two mounting parts 12 disposed at both ends of the connecting part 11. The two mounting parts 12 are arranged opposite to each other. An air duct 124 is provided in the mounting part 12, and multiple first air outlets 121, multiple second air outlets 122 and an air inlet 126 are provided in the air duct 124. The first air outlets 121 and the second air outlets 122 are arranged vertically at intervals. The multiple first air outlets 121 are arranged at intervals along the length of the air duct 124. The multiple air outlets are arranged vertically at intervals along the length of the air duct 124. A fan 20 is rotatably installed in the air duct 124 to drive the external airflow into the air duct 124 through the air inlet 126 and then out through the multiple first air outlets 121 and the multiple second air outlets 122. This allows air to be emitted simultaneously from multiple first air outlets 121 and multiple second air outlets 122, enabling users to receive airflow from these outlets and thus effectively increasing the air volume of the neck fan and improving its cooling performance.

[0037] In some embodiments, the first air outlet 121 is located on the top surface of the mounting portion 12, and the second air outlet 122 is located below the first air outlet 121. Specifically, when a user wears the neck fan, the airflow blown from the first air outlet 121 blows toward the user's face, and the airflow blown from the second air outlet 122 blows toward the user's neck.

[0038] In some embodiments, the mounting portion 12 is further provided with a third air outlet 123, which is connected to a ventilation 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, a plurality of second air outlets 122, and a third air outlet 123. This arrangement 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 123.

[0039] 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.

[0040] In some embodiments, the mounting part 12 is further provided with a mounting cavity 125, and the neck fan also includes a circuit assembly installed in the mounting cavity 125. The mounting cavity 125 and the air duct 124 are separated by a partition 30. The partition 30 is provided with a ventilation hole 31, which connects the air duct 124 and the mounting cavity 125. The mounting part 12 is also provided with a heat dissipation hole, which connects to the mounting cavity 125.

[0041] Specifically, when the neck fan is in use, the circuit components generate heat. By providing ventilation holes 31 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 completed, 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 31.

[0042] In some embodiments, the neck fan further includes a display screen 60, which is disposed on the outer side of the mounting portion 12 and electrically connected to the circuit components. Specifically, the display screen 60 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 60 can also be used to display the speed setting of the fan 20. For example, the display screen 60 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.

[0043] In some embodiments, the neck fan further includes a roller 40, which is rotatably mounted on the mounting part 12 for adjusting the power of the fan 20. The user 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 turned to adjust the fan speed.

[0044] In some embodiments, the outer peripheral surface of the roller 40 is provided with an anti-slip portion. The protective 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 60 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 60, thus facilitating adjustment according to their needs. Simultaneously, placing the display screen 60 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 60 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 description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
