[0029] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0030] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0032] An embodiment of this utility model provides a rotary fan with an adjustable air outlet angle, such as... Figure 1-3As shown, the fan body 100 and two supports 200 are included. The fan body 100 is provided with an air inlet, which can be set on the front, rear, left, right, top, bottom or other positions of the fan body 100 as needed. The front side of the fan body 100 is provided with an air outlet 102. When the fan body 100 is working, air enters the fan body 100 from the air inlet and is then blown out through the air outlet 102. Two supports 200 are respectively disposed on the left and right sides of the fan body 100. The left and right sides of the fan body 100 are rotatably connected to the two supports 200, with at least one side being damped and rotatably connected to the support 200. Specifically, the left side of the fan body 100 is damped and rotatably connected to the adjacent support 200, and the right side of the fan body 100 is rotatably connected to the adjacent support 200; or, the left side of the fan body 100 is rotatably connected to the adjacent support 200, and the right side of the fan body 100 is damped and rotatably connected to the adjacent support 200; or, the left side of the fan body 100 is damped and rotatably connected to the adjacent support 200, and the right side of the fan body 100 is damped and rotatably connected to the adjacent support 200.

[0033] Users can rotate the fan body 100 to a suitable angle according to their needs. The orientation of the air outlet 102 will change with the rotation of the fan body 100, and the air outlet angle will also change accordingly. Because the fan body 100 and the bracket 200 are connected by a damped rotation, the fan body 100 will maintain its angle under the action of damping force and will not return to its original position under its own weight. Therefore, the air outlet angle can be adjusted as needed, making it more widely applicable. Figure 2 For example, Figure 2 The blower body 100 blows air to the right, and the blower body 100 can be rotated counterclockwise to form... Figure 3 state, Figure 3 The fan body 100 in the middle blows air to the left.

[0034] In some embodiments, such as Figure 4-8 As shown, a protruding elastic pin 210 is provided on the inner side of the bracket 200 located on the left side of the fan body 100 (the side where the two brackets 200 are close to each other). Multiple slots 103 are provided on the left side of the fan body 100. The slots 103 are distributed circumferentially around the axis of rotation of the fan body 100 relative to the bracket 200. The elastic pin 210 abuts against the left side of the fan body 100 and can be inserted into the slot 103.

[0035] The elastic pin 210 can elastically extend and retract. When the fan body 100 rotates relative to the bracket 200, the elastic pin 210 rotates relative to the left side of the fan body 100. Due to the presence of the slot 103, when the fan body 100 rotates until the slot 103 is opposite to the elastic pin 210, the elastic pin 210 inserts into the slot 103. This restricts the fan body 100 from rotating relative to the bracket 200 on its own. The user needs to forcefully pry the fan body 100 to disengage the elastic pin 210 from the slot 103, allowing the fan body 100 to continue rotating. Thus, in this embodiment, the damped rotational connection between the fan body 100 and the bracket 200 is achieved through the cooperation of the elastic pin 210 and the slot 103.

[0036] Furthermore, two travel limit blocks 104 are provided on the left side of the fan body 100. Both travel limit blocks 104 are located on the rotation path of the elastic pin 210 on the left side of the fan body 100. Therefore, when the fan body 100 rotates, the travel limit blocks 104 can abut against the elastic pin 210, thereby restricting the elastic pin 210 from rotating in the original direction. The fan body 100 also cannot rotate further relative to the support 200. In this way, the maximum angular position of the fan body 100 in a certain rotation direction can be limited. The two travel limit blocks 104 can limit the angular range of the fan body 100 relative to the support 200 to prevent the fan body 100 from rotating too much.

[0037] In some embodiments, rotating rings 105 are provided on both the left and right sides of the fan body 100. The rotating rings 105 on the left and right sides of the fan body 100 are coaxially arranged. Both supports 200 are provided with through holes 220 adapted to the rotating rings 105. The rotating rings 105 are inserted into the through holes 220 and can rotate within the through holes 220, thereby allowing the fan body 100 to rotate relative to the supports 200. At the same time, since the rotating rings 105 are inserted into the through holes 220, the rotating rings 105 can provide support for the fan body 100, keeping it stable.

[0038] Furthermore, both the left and right sides of the fan body 100 are provided with bosses 106, and the rotating ring 105 is located on the outer side of the bosses 106. The inner sides of both supports 200 are provided with raised rings 230 around the through holes 220, and the bosses 106 abut against the raised rings 230. The abutment of the bosses 106 restricts the outward movement of the fan body 100, preventing excessive contact area between the fan body 100 and the supports 200 from affecting the rotation of the fan body 100.

[0039] In some embodiments, each of the two supports 200 has a cover plate 240 on its outer side. The outer diameter of the cover plate 240 is larger than the diameter of the through hole 220, so the cover plate 240 cannot pass through the through hole 220. The cover plate 240 is fixedly connected to the fan body 100. This restricts the fan body 100 from moving inward, making it difficult for the fan body 100 to detach from the support 200, thus ensuring the rotational connection between the fan body 100 and the support 200.

[0040] In some embodiments, such as Figure 1 and Figure 9 As shown, the adjustable-angle rotary fan also includes a connecting arm 300. Both ends of the connecting arm 300 are connected to two supports 200, thus connecting the two supports 200 and improving their stability. The connecting arm 300 can also function as a handle, allowing the user to grip it and lift the entire fan.

[0041] In some embodiments, such as Figure 1 and Figure 9 As shown, the adjustable air outlet angle rotary fan also includes a base 400, which is located between two supports 200, and both sides of the base 400 are fixedly connected to the two supports 200 respectively. Connecting the two supports 200 through the base 400 can also improve the stability of the two supports 200.

[0042] Furthermore, a battery 410 is fixed on the base 400. The battery 410 is connected to the fan body 100 and will supply power to the fan body 100. Users can place the fan of this embodiment in a suitable position as needed without having to worry about the trouble of external power supply, which further expands the applicability of the fan.

[0043] In some embodiments, such as Figure 1 and Figure 9 As shown, air inlets 101 are provided on both the left and right sides of the fan body 100, and through openings 201 are provided on the bracket 200 to reduce obstruction of the air inlets 101.

[0044] In some embodiments, such as Figure 1 and Figure 9 As shown, the fan body 100 includes an outer casing, which includes a detachable left casing 110 and a right casing 120. The split structure facilitates the assembly of other components into the outer casing.

[0045] Furthermore, a fan wheel 130 is installed inside the outer casing. The fan wheel 130 can be a bidirectional air intake fan wheel to increase the air intake volume.
