[0001] The utility model relates to the technical field of neck fans, and particularly relates to an air outlet structure of a neck fan and a neck fan. Background Art

[0002] Compared with traditional hand-held small fans, neck fans can free hands and solve the problem of restricted hand movement when using hand-held fans, so as to meet the convenience of modern life. Users can easily enjoy the blowing wind in outdoor activities or indoor scenarios. Therefore, neck fans are increasingly favored by the public.

[0003] At present, the neck fans in the prior art are composed of two hanging arms, in the shape of a "C" shape with an opening. Its air inlet is generally arranged on the side of the lower part of the two hanging arms, and the air outlets are arranged on the side of the middle part of the two hanging arms. And because the size of the air outlets is relatively small, generally multiple air outlets are arranged. Since multiple small air outlets are arranged on the side of the middle part of the hanging arms, it will affect the assembly of the battery in the middle part of the hanging arms. In order to assemble the battery, the structure will be relatively complex, and the space inside the shell is small, making it difficult to place a large-capacity battery. In addition, because the size of the air outlets is relatively small, the air volume will be small, resulting in a poor user experience. Summary of the Utility Model

The hanging arm 1 includes an inner shell 11, an outer shell 12, and an air inlet 13 provided at the bottom of the hanging arm. The inner shell 11 is provided with a waist-shaped slot air outlet 14 that is curved inward in an arc shape. A waist-shaped slot through hole is provided at the bottom of the waist-shaped slot air outlet 14. A grille air duct device 2 is installed at the waist-shaped slot through hole. A fan blade 3 is connected below the grille air duct device 2; wherein, the grille air duct device 2 and the fan blade 3 are arranged in the inner cavity of the hanging arm 1.

[0042] The air outlet structure of a neck-mounted fan of the present utility model. Since the air inlet 13 is provided at the bottom of the hanging arm 1, and the inner shell 11 is provided with a kidney-shaped groove air outlet 14 that is curved in an arc shape inward, and a fan blade 3 is connected below the grille air duct device 2, and the fan blade 3 is arranged between the air inlet 13 and the grille air duct device 2. In actual application, when the fan blade 3 is started, the air flow enters from the air inlet 13, passes through the grille air duct device 2 and is blown out from the kidney-shaped groove air outlet 14. Since the size of the kidney-shaped groove air outlet 14 is relatively large, and the kidney-shaped groove air outlet 14 is curved in an arc shape inward, the air flow can be blown upward along the arc-shaped curved surface of the kidney-shaped groove air outlet 14. Therefore, not only can the air volume be relatively large, but also the air can be sent in a large range.

[0043] In this embodiment, the grille air duct device 2 includes a circular main body 21 and a plurality of air duct holes 22 that are circumferentially provided at the outer peripheral edge of the circular main body 21.

In actual application, when the fan blade 3 is started, air flow enters from the air inlet 13, passes through the grille air duct device 2 and is blown out from the kidney-shaped groove air outlet 14. Since the size of the kidney-shaped groove air outlet 14 is relatively large and the kidney-shaped groove air outlet 14 curves inward in an arc shape, the air flow can be blown upward along the arc-shaped curved surface of the kidney-shaped groove air outlet 14. Therefore, not only can the air volume be relatively large, but also the air can be sent over a large range. Therefore, this neck fan can generate a large air volume, has a simple structure, and has a large space inside the shell, which is convenient for placing a large-capacity battery, and can well improve the user experience.

[0049] In this embodiment, a battery 5 is further arranged in the inner cavity of the hanging arm 1, and the battery 5 is arranged above the kidney-shaped groove air outlet 14. Since there is no need to arrange an air duct above the kidney-shaped groove air outlet 14, more space can be left for placing a large-capacity battery 14, and thus the air volume can be further increased.

[0050] In this embodiment, a control circuit board 6 is further arranged below the battery 5, and a switch button 7 is arranged on the control circuit board 6. Through this switch button 7, the rotation of the fan blade 3 can be started, so that the air flow is brought into the inner cavity of the hanging arm 1 through the air inlet 13, and then passes through the grille air duct device 2 and is blown out from the kidney-shaped groove air outlet 14.

[0051] In this embodiment, an arc-shaped block 41 is fixedly connected below the middle connecting member 4. This arc-shaped block 41 is used to fit the user's neck and can enable stable wearing.

[0052] In this embodiment, a plurality of circular convex points 42 are arranged on the lower side surface of the arc-shaped block 41. The arranged circular convex points 42 can leave a gap between the arc-shaped block 41 and the user's neck, and thus there can be a certain air flow between the arc-shaped block 41 and the user's neck. When the user's neck sweats, the sweat is also easily dissipated through the gap, so that the user experience can be better improved.

[0053] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
