[0002] The waist-mounted fan is a portable personal cooling device specially designed for use in summer or high temperature environments to provide users with an instant cooling sensation.

[0003] In the traditional waist-hanging fan design, large-diameter traditional fan blades are usually used. Although this design can provide a certain amount of wind force, it has many inconveniences in actual use. First of all, the large-diameter fan is large in size. When hung on the waist, it often forms a noticeable bulge on the outside of the user's clothes, which not only affects the user's appearance, but also may cause obstacles in certain activities. In addition, the design of this traditional fan usually has a single function and cannot meet the diverse needs of users.

[0004] In order to solve the problems of aesthetics and portability, the industry has tried to reduce the size of fans. However, the reduction in size often comes at the expense of wind power, resulting in poor cooling effect, especially in outdoor activities that require strong wind cooling, the performance of such small fans is often unsatisfactory.

[0005] In terms of versatility, traditional waist-mounted fans are usually limited to providing cooling functions, but cannot meet other daily needs, such as when stronger and more targeted wind is needed to clean the gaps of electronic devices. Users have to carry an additional blower, which is not conducive to the multi-functional use of waist-mounted fans.

[0006] Furthermore, traditional waist-hanging fans are often simply designed in a waist-hanging manner and cannot adapt to the different waist shapes and clothing of different users. It is easy for the fan position to be unstable or the air inlet and outlet to be blocked by clothing, thereby affecting the use effect of the fan.

[0007] Therefore, how to balance the aesthetics, portability, wind power and versatility of the waist-hanging fan and ensure that the fan can be stably hung on the user's waist without being affected by clothes has become a technical problem to be solved by the utility model. Utility Model Content

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 —6. In an embodiment of the utility model, a foldable waist-hanging fan which can be used as a hair dryer in a handheld state comprises a fan body 1, a waist-hanging support structure 2 and a hanging buckle 3; the fan body 1 comprises an air gun tube 4 and a turbo fan 5, the air gun tube 4 comprises an air channel 6 and an air inlet 7 and an air outlet 8 connected to the air channel 6, and the turbo fan 5 is fixedly arranged in the air channel 6; the waist-hanging support structure 2 comprises a front face, a back face and an end face, and the hanging buckle 3 is arranged on the front face and / or the back face of the waist-hanging support structure 2; one end portion of the waist-hanging support structure 2 is rotatably connected to the side portion of one end of the fan body 1; a hanging ring 18 for connecting a hanging rope can be fixedly arranged on the fan body 1, all of which belong to extended implementation methods known to ordinary technicians in this field.

[0038] The hook 3 includes a first hook 16 and a second hook 17. The first hook 16 and the second hook 17 are respectively arranged on the front and back of the waist-hanging support structure 2. The hook 3 directions of the first hook 16 and the second hook 17 are opposite. One end of the waist-hanging support structure 2 is connected to one end of the fan body 1 by a rotating shaft 9, and the friction force of the rotating cooperation can be adopted to ensure that the fan can automatically stop at any rotation position, so as to be more convenient and stable when used. The value of the friction force needs to be large enough to maintain its position, but not too large to avoid difficulty in rotation.

[0039] For example, to estimate this friction value, you can consider the following aspects:

[0040] First of all, the functional requirements need to ensure that the fan can remain fixed at different angles to prevent position changes due to gravity or slight vibrations during use. At the same time, the friction should not be too large to avoid users having to work hard when adjusting.

[0041] The second is material and design. The materials of the rotating shaft and the connecting seat are usually plastic, metal or oil-containing bearings. The use of coating or lubricant can reduce the friction coefficient and maintain a certain friction force.

[0042] At the same time, the design parameters of existing products can also be referred to. The friction design of similar waist-mounted fans or handheld devices can provide valuable references.

[0043] Assuming that an average user can comfortably adjust the fan position with a torque between 0.2 and 0.5 Nm. Combined with the weight of the fan (assumed to be 0.5 kg) and the length of the fan (assumed to be 15 cm), the range of friction can be estimated as follows:

[0044] Torque is force times arm length. Based on the torque range (0.2 to 0.5 Nm) and arm length (0.15 m), we can calculate friction. The minimum friction is 0.2 divided by 0.15, which equals 1.33 Newtons, and the maximum friction is 0.5 divided by 0.15, which equals 3.33 Newtons.

[0045] In summary, the rotational cooperation friction between the fan body and the waist-hanging support structure ranges from about 1.33 to 3.33 Newtons. This range should be sufficient to ensure that the fan is fixed at any position, and is also convenient for users to adjust. All of these belong to extended implementation methods known to ordinary technicians in the field. So that it can stop automatically at any rotation position. The length of the air gun tube 4 is 5cm-8cm. The shape of the waist-hanging support structure 2 is a long strip.

[0046] The foldable waist-hanging fan which can be used as a hair dryer in the handheld state also includes a first buckle 10 and a second buckle 11. The fan body 1 includes one end and the other end. The outer side surface of one end of the fan body 1 is fixedly provided with the first buckle 10, and the outer side surface of the fan body 1 close to the other end is fixedly provided with the second buckle 11. One end and one side of the waist-hanging support structure 2 are respectively provided with a first buckle groove 12 and a second buckle groove 13 which match the first buckle 10 and the second buckle 11. The fan body 1 includes an unfolded state and a folded state. When the fan body 1 is in the unfolded state, the first buckle 10 is snap-connected with the first buckle groove 12. When the fan body 1 is in the folded state, the second buckle 11 is snap-connected with the second buckle groove 13. The fan body 1 is rotatably connected with the waist-hanging support structure 2 through a connecting seat 14. It also includes a rotating bracket 15, which is rotatably connected with the first hanging buckle 16.

[0047] Embodiment 1:

[0048] The present embodiment provides a foldable waist-hanging fan that can be used as a hair dryer in a handheld state. The design of the fan is intended to solve the problems of traditional waist-hanging fans in terms of aesthetics, portability, functional diversity and adaptability.

[0049] Specifically, the folding waist-hanging fan includes a fan body 1, a waist-hanging support structure 2 and a hanging buckle 3. The fan body 1 is composed of an air gun tube 4 and a turbofan 5, wherein the air gun tube 4 is provided with an air inlet 7 and an air outlet 8, and a turbofan 5 is fixed inside to generate wind. The waist-hanging support structure 2 is in the shape of an elongated strip, and one end thereof is rotatably connected to the side of one end of the fan body 1 through a rotating shaft 9, so that the fan body 1 can switch freely between the unfolded state and the folded state. This design significantly reduces the volume of the fan in the folded state, making it easy to carry. At the same time, it solves the bulge problem caused by traditional large fans at the waist and improves the aesthetics.

[0050] In addition, the fan is also equipped with a first buckle 10 and a second buckle 11, and a first buckle slot 12 and a second buckle slot 13. When the fan is in the unfolded state, the first buckle 10 is engaged with the first buckle slot 12 to ensure the stability of the fan during use; when the fan is folded, the second buckle 11 is engaged with the second buckle slot 13 to facilitate carrying and storage.

[0051] The hook 3 part includes a first hook 16 and a second hook 17 arranged on the front and back of the waist support structure 2. The hook directions of the two hooks 3 are opposite, so that the fan can be firmly hung on the user's waist, adapting to the waist shape and wear of different users, and avoiding the situation where the fan position is unstable or the air inlet and outlet 8 are blocked by clothes.

[0052] It is worth mentioning that the air gun tube 4 of the fan is designed to be 5cm to 8cm long. This length not only ensures the portability of the fan, but also can be used as a blow gun in a handheld state to meet the diverse needs of users, such as cleaning the gaps of electronic equipment.

[0053] In order to further enhance the adaptability and versatility of the fan, the embodiment further includes a rotating bracket 15, such as Figure 7 As shown, the bracket is rotatably connected with the first hook 16, so that the fan can be used flexibly in more scenarios. The rotating bracket 15 can be supported and placed on the desktop when needed, which are all extended implementation methods known to ordinary technicians in this field.

[0054] In summary, the foldable waist-hanging fan provided in this embodiment solves the problems of traditional waist-hanging fans in terms of aesthetics, portability, functional diversity and adaptability through innovative design, providing users with a practical and convenient cooling device in summer or high temperature environments.

[0055] Embodiment 2:

[0056] The waist-hanging fan uses a small-diameter cylindrical turbofan 5. Compared with the traditional large fan blades, this design can better fit the narrow space between the user's waist and clothes. When the user hangs the fan on the waist, it will not cause obvious bulges on the outside of the clothes, thus maintaining the aesthetics of the user's clothing.

[0057] Furthermore, this small-diameter cylindrical turbofan 5 is not only a cooling device. In a handheld state, it can be quickly transformed into an efficient air gun. Since the wind force generated by the turbofan 5 is particularly strong, it becomes a powerful tool for blowing and cleaning. For example, when maintaining electronic equipment or cleaning a workbench, the user can easily blow away dust and debris, thereby improving work efficiency and protecting the normal operation of the equipment.

[0058] In addition, the waist-mounted fan in this embodiment adopts a long strip folding design. This design is not only easy to carry and store, but also provides a better grip and operability when the user holds it in hand. Whether it is necessary to quickly cool down during outdoor activities or to clean the workplace, this design provides great convenience for users.

[0059] Finally, the hook 3 of the waist-hanging fan adopts a two-way relative waist-hanging structure. This structure not only makes the waist-hanging angle more diverse and meets the needs of different users, but also plays the role of hanging the waist on one side and limiting the position of clothes on the other end. In this way, even during activities or walking, clothes will not block the air inlet and outlet 8 of the fan, ensuring the continuous and effective operation of the fan.

[0060] In summary, this embodiment significantly improves the aesthetics, portability, functional diversity and adaptability of the waist-hanging fan by adopting the small-diameter cylindrical turbofan 5, the long strip folding design and the two-way relative waist-hanging structure.
