Technical Field

[0001] This application relates to the field of fan technology, and in particular to a waist-mounted fan. Background Technology

[0002] In daily life, people often need to stay cool while exercising or working outdoors, or in indoor environments without air conditioning. While traditional handheld fans are portable, they require constant handholding, which can easily lead to arm fatigue and distractions during other activities. Furthermore, handheld fans have limited airflow range, making it difficult to meet people's needs for comprehensive and continuous cooling.

[0003] To facilitate continuous cooling, waist-mounted fans are used to continuously cool users. However, traditional waist-mounted fans have a fixed airflow direction, making it difficult to adjust them flexibly according to the user's individual needs. Utility Model Content

[0004] The purpose of this application is to provide a waist-mounted fan that can adjust the airflow direction according to the user's needs, making the user more comfortable to use.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0026] A type of waist-mounted fan, see reference Figure 1 and Figure 2The fan body includes a fan body 1 and an air guide frame 2. The fan body 1 has an air outlet 11 at its upper end, through which the air generated inside the fan body 1 flows to blow air onto the user. A hook 6 is fixedly connected to the fan body 1, allowing it to be hung around the user's waist when used as a waist-mounted fan. The air guide frame 2 is rotatably connected to the fan body 1 and located at the air outlet 11. Air from the fan body 1 flows into the air guide frame 2 through the air outlet 11, and after being guided by the air guide frame 2, it is blown out from it. Because the air guide frame 2 is rotatably connected to the fan body 1, rotating the air guide frame 2 adjusts its angle, thereby regulating the direction of the airflow.

[0027] One part of the air guide frame 2 is inserted into the air outlet 11, and the other part is located outside the air outlet 11, ensuring that almost all the air inside the main body is discharged through the air guide frame 2.

[0028] Specifically, a rotating shaft 3 is fixedly connected to the side wall of the air guide frame 2, and the rotating shaft 3 is rotatably connected to the fan body 1, thereby realizing the rotatable connection between the air guide frame 2 and the fan body 1.

[0029] Reference Figure 2 and Figure 3 Specifically, a mounting platform 12 is fixedly connected to the fan body 1. The mounting platform 12 has a mounting groove 13. The mounting groove 13 is adapted to the shape of the rotating shaft 3. The rotating shaft 3 is placed in the mounting groove 13 and can rotate in the mounting groove 13. By setting the mounting groove 13, the situation of the rotating shaft 3 sliding in the radial direction on the fan body is restricted.

[0030] Furthermore, at least two rotating shafts 3 are provided, with at least two rotating shafts 3 distributed on both sides of the air guide frame 2. The aforementioned mounting platform 12 is provided at both rotating shafts 3, and both rotating shafts 3 are rotatably connected to the fan body 1 through the corresponding mounting platform 12. Because two rotating shafts 3 are provided, the rotation of the air guide frame 2 is more stable, reducing the occurrence of positional displacement of the air guide frame 2.

[0031] Furthermore, each mounting platform 12 is provided with an arc-shaped groove 14, and each rotating shaft 3 is fixedly connected with a limiting ring 31. The limiting ring 31 can be inserted into the corresponding arc-shaped groove 14 and rotate in the corresponding arc-shaped groove 14. During the rotation of the rotating shaft 3, the limiting ring 31 rotates in the arc-shaped groove 14. By setting the limiting ring 31, the sliding of the rotating shaft 3 along its own axis is restricted, which further ensures the stability of the rotation of the air guide frame 2.

[0032] Furthermore, the waist-mounted fan also includes a fixing cover plate 4, which is provided with a buckle 5. The fixing cover plate 4 is fixed to the fan body 1 by the buckle 5. The rotating shaft 3 is arranged in a straight line between the fixing cover plate 4 and the fan body 1. The fixing cover plate 4 restricts the rotating shaft 3 from detaching from the fan body 1 and facilitates the installation and replacement of the air guide frame 2.

[0033] Specifically, the fixed cover plate 4 is provided with several of the above-mentioned buckles 5, and the fan body 1 is provided with several L-shaped slots 15. When the rotating shaft 3 is installed on the mounting platform 12 and the limiting ring 31 is inserted into the arc-shaped groove 14, the buckles 5 are inserted into the corresponding slots 15, thereby fixing the fixed cover plate 4 to the fan body 1 and limiting the rotating shaft 3, reducing the occurrence of the rotating shaft 3 coming off during rotation.

[0034] The aforementioned mounting base is also fixedly connected to the fixed cover plate 4. When the fixed cover plate 4 is fixed on the fan body 1, the two corresponding mounting bases abut against each other, so that the two corresponding arc grooves 14 form an annular groove. The limiting ring 31 is rotatably set in the annular groove, which further increases the limiting of the rotating shaft 3 and ensures the stability of the rotating shaft 3.

[0035] Furthermore, the limiting ring 31 is provided with a friction surface, which abuts against the inner wall of the arc-shaped groove 14 and is used to limit the rotation of the rotating shaft 3. Through the friction between the friction surface and the inner wall of the arc-shaped groove 14, and through the frictional force between the limiting ring 31 and the inner wall of the arc-shaped groove 14, the rotation of the air guide frame 2 due to its own weight is limited. The air guide frame 2 can be fixed at any angle, achieving stepless adjustment and facilitating user operation. In other embodiments, bolts can be screwed onto the side wall of the mounting base. By rotating the bolts, the bolts are tightened against the rotating shaft 3, thereby achieving stepless adjustment of the air guide frame 2.

[0036] Reference Figure 3 and Figure 4 Furthermore, a protrusion 32 is fixedly connected to the rotating shaft 3, and a limiting groove 16 is provided on the fan body. The protrusion 32 can be inserted into the limiting groove 16 and can rotate within the limiting groove 16. The limiting groove 16 is used to limit the rotation angle of the protrusion 32. Specifically, the limiting groove 16 is provided on the mounting platform 12. By limiting the length of the limiting groove 16, the rotation angle of the protrusion 32 is limited, thereby limiting the rotation angle of the air guide frame 2 and preventing the air guide frame 2 from rotating excessively.

[0037] In this embodiment, the rotatable angle of the protrusion 32 is between 33° and 34°. Preferably, the rotatable angle of the protrusion 32 is 33.8°. Within this range, the air guide frame 2 is always blowing air upwards or diagonally upwards to cool the user's upper body and make the user more comfortable.

[0038] Furthermore, an air guide plate 21 is fixedly connected inside the air guide frame 2. The air guide plate 21 cuts the air inside the air guide frame 2, reducing the size of the flow channel, which helps to increase the air pressure and improve the user experience.

[0039] Furthermore, there are several air guide plates 21 arranged in parallel within the air guide frame 2. Compared to a single air guide plate 21, the arrangement of multiple air guide plates 21 is more conducive to increasing air pressure and has a better effect.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
