Description

Technical Field

[0001] This utility model relates to the field of fans, specifically to a folding fan. Background Technology

[0002] Fans are common everyday items and play an indispensable role in people's daily lives.

[0003] The most common types of fans on the market are banana leaf fans and paper folding fans.

[0004] Banana leaf fans have been used for hundreds of years, but they are not easy to carry, store, or preserve.

[0005] The folding fans commonly found on the market usually have 15 ribs. With so many ribs, the manufacturing process is complex. The fan surface is fixed to the ribs by gluing, which makes it easy for the ribs to fall off. They are also not easy to unfold or close. In addition, the fans on the market are usually made of paper, which is easily damaged, resulting in a short lifespan for folding fans.

[0006] There are cartoon fans available on the market for children, which are fans formed by multiple blades and a rotating handle. However, some of these fans cannot maintain a fixed rotation angle, making them inconvenient to use and ineffective at dispelling heat; some use a limiting structure at the handle connection, which is complex to manufacture and increases costs; while others are connected by cotton thread, which is easy to break and impractical.

[0007] Fans have been with humankind for thousands of years. Today, with a wealth of new materials and technologies, it is essential to invent a fan that can generate a breeze as powerful as a banana leaf fan, yet is easy to open and close, portable, easy to store, convenient to use, and has advantages such as low production cost, long service life, good performance, and beautiful and durable. Utility Model Content

[0008] The purpose of this utility model is to provide a folding fan that solves the problems of outdated technology, high production cost, short service life and poor performance of existing fans.

[0009] To achieve the purpose of this utility model, a folding fan is provided, comprising fan blades and fan handles. The number of fan blades is at least two, and the number of fan handles is the same as the number of fan blades. The first ends of multiple fan handles are fixedly connected together, and the second end of each fan handle is connected to a fan blade. The folding fan also includes connecting members, which are disposed between two adjacent fan blades. A connecting member is provided between every two adjacent fan blades. One end of the connecting member is connected to one fan blade, and the other end of the connecting member is connected to another fan blade. The connecting member is made of soft ribbon material or bendable plastic material.

[0010] As can be seen from the above solution, the folding fan of this utility model is equipped with a connector, which connects the fan blades to each other to form a whole and limits the degree of opening and closing of the folding fan, ensuring the effectiveness of the folding fan and bringing a good heat-relieving effect. At the same time, the manufacturing process is simple and the manufacturing cost is low. In addition, the connector is made of plastic or ribbon, which are widely available, further reducing the manufacturing cost of the folding fan. The stable chemical properties of plastic make it have excellent durability, water resistance and corrosion resistance, and can effectively resist the erosion of natural environment such as oxygen, moisture and ultraviolet rays, as well as physical damage such as tearing or impact. This means that the connector made of plastic is not easily damaged after long-term use, thus ensuring the service life of the folding fan. Ribbon is usually made of high-strength and wear-resistant materials, with good durability and anti-aging properties. At the same time, ribbon also has a certain drape, so when the fan blades are folded and closed, it will not affect the appearance of the folding fan or increase the space occupied by the folding fan, making it more durable and convenient.

[0011] A further embodiment is that the folding fan includes a fastener for connecting the fan blades and the connector. Preferably, the fastener is a staple.

[0012] As can be seen from the above scheme, the fan blades and the connecting parts are connected by fasteners, which achieves a stable connection between the fan blades and the connecting parts. This stable connection helps to ensure the stability and reliability of the fan blades during the opening and closing process. Using staples as fasteners also simplifies the assembly process of the fan blades, making it faster and more convenient, reducing production costs and improving production efficiency.

[0013] A further option is to place the connector at the end of the fan blade away from the handle.

[0014] As can be seen from the above solution, the structure helps to balance the weight and stress of the fan blades. This balance not only improves the durability of the fan blades but also ensures their stability and efficiency during opening and closing rotation. Furthermore, the structure facilitates the installation and positioning of the fixing components.

[0015] A further option is to have at least three fan blades, with the first fan blade having two connecting pieces. One of the connecting pieces is located on the first surface of the first fan blade, and the other connecting piece is located on the second surface opposite to the first surface of the first fan blade.

[0016] As can be seen from the above scheme, the above structure enhances the stability and reliability of the fan blades, optimizes the force distribution of the fan blades, and the two connecting parts are located on the two sides of the fan blades respectively, which can more evenly distribute the force on the fan blades during opening and closing rotation, and avoid the deformation or damage of the fan blades caused by uneven force.

[0017] A further solution is to provide a first through hole on the fan blade and a second through hole on the second end of the fan handle, with the first and second through holes corresponding to each other to achieve interconnection between the fan blade and the fan handle.

[0018] As can be seen from the above scheme, the fan blades and fan handle are fixed by rivets or screws passing through the through holes, which is simple in structure and stable in connection.

[0019] A further solution is to provide a third through hole at the first end of the fan handle, through which multiple fan handles are connected.

[0020] As can be seen from the above scheme, the fan handle is provided with a third through hole, which can be used to fix multiple fan handles with rivets. The structure is simple, the assembly is convenient, and the stability and smoothness of the fan handle rotation are also guaranteed.

[0021] A further solution is to make the width at both ends of the fan handle greater than the width in the middle of the fan handle.

[0022] As can be seen from the above solution, the structure not only enhances the strength and stability of the fan handle and fan blades, and the fan handle and fan blades, enabling it to better support the fan blades and withstand the force during rotation, but also improves the overall durability; at the same time, the above also optimizes the user's feel, making it more comfortable to hold the fan handle and less likely to slip.

[0023] A further design is to make the fan blades approximately trapezoidal or pear-shaped, with the width of the side of the fan blade furthest from the handle being greater than the width of the side of the fan blade closest to the handle.

[0024] As can be seen from the above design, the shape of the fan blades optimizes their aerodynamic performance, allowing airflow to pass more smoothly and improving ventilation efficiency. Simultaneously, this near-trapezoidal design enhances the thrust of the blades, enabling the fan to generate stronger winds during use. Furthermore, the trapezoidal blades increase the fan's aesthetics, making it more design-oriented and visually appealing. The pear-shaped blades, when assembled, form a fan shape.

[0025] A further option is to make both the fan blades and the fan handle from plastic.

[0026] As can be seen from the above solutions, the plastic material makes the fan blades and handle lightweight, easy to carry and use. At the same time, plastic's high plasticity allows for the easy manufacture of fan blades and handles in various shapes and colors to meet different aesthetic and functional needs. Furthermore, plastic is waterproof and has good weather resistance and corrosion resistance, resisting wear and corrosion from daily use and extending the fan's lifespan. Moreover, plastic is relatively inexpensive, helping to reduce production costs.

[0027] A further option is to use a rectangular sheet-like structure for the connector.

[0028] As can be seen from the above solution, the rectangular sheet structure provides stable connection support, ensuring a firm connection between the connector and the fan blade, effectively preventing loosening or detachment. The rectangular sheet shape allows for even distribution of force when the connector is under load, enhancing overall load-bearing capacity and stability. Furthermore, the rectangular structure simplifies the processing and installation process, improves production efficiency, and makes it easier for the connector to fit and secure with the fan blade. The rectangular sheet structure also has an aesthetic appeal, enhancing the overall appearance and texture of the product. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] See Figures 1 to 4 The folding fan provided in this embodiment includes fan blades 1, fan handles 2, and connectors 3. The number of fan blades 1 is at least two; in this embodiment, the number of fan blades 1 is seven. The number of fan handles 2 is the same as the number of fan blades 1; in this embodiment, the number of fan handles 2 is also seven. The first ends of multiple fan handles 2 are fixedly connected together, and the second end of each fan handle 2 is connected to one fan blade 1. Connectors 3 are disposed between two adjacent fan blades 1; a connector 3 is provided between every two adjacent fan blades 1. One end of the connector 3 is connected to one fan blade 1, and the other end of the connector 3 is connected to another fan blade 1. The connector 3 is made of soft ribbon material or bendable plastic material.

[0037] Specifically, the folding fan also includes a fixing member 4, which is used to connect the fan blades 1 and the connecting member 3. In this embodiment, the fixing member 4 is a staple.

[0038] In this embodiment, the fan blade 1 connected by two connectors 3 is a first fan blade 13. One connector 3 is provided on the first surface of the first fan blade 13, and the other connector 3 is provided on the second surface opposite to the first surface of the first fan blade 13. The above connection method enhances the stability and reliability of the fan blade 1 and optimizes the force distribution of the fan blade 1. The two connectors 3 are located on two different surfaces of the fan blade 1, which can more evenly distribute the force on the fan blade 1 during opening and closing rotation, avoiding deformation or damage to the fan blade 1 caused by uneven force distribution.

[0039] The fan blade 1 has a first through hole 11, and the second end of the fan handle 2 has a second through hole 21. The first through hole 11 and the second through hole 21 correspond to each other, and the fan blade 1 and the fan handle 2 can be connected by rivets passing through the through holes. Specifically, in this embodiment, a notch 12 is provided at the end where the fan blade 1 connects to the fan handle 2. The notch 12 further facilitates the connection and fit between the fan blade 1 and the fan handle 2, ensuring that the folding fan has a moderate thickness after folding and will not cause compression damage to the fan blade 1. See also Figure 5 The handle 2 can be fixed to one side of the fan blade 1, see [reference]. Figure 6 Alternatively, a groove can be made at the second end of the fan handle 2, the fan blade 1 can be inserted into the groove, and then fixed using the first through hole 11 and the second through hole 21.

[0040] Preferably, in this embodiment, a third through hole 22 is provided at the first end of the fan handle 2, and multiple fan handles 2 can be connected by rivets passing through the third through hole 22.

[0041] Preferably, in this embodiment, the fan blade 1 is approximately trapezoidal or pear-shaped, and the width of the fan blade 1 on the side away from the fan handle 2 is greater than the width of the fan blade 1 on the side closer to the fan handle 2. The width at both ends of the fan handle 2 is greater than the width in the middle of the fan handle 2. The connector 3 is a rectangular sheet structure.

[0042] Preferably, in this embodiment, both the fan blades 1 and the fan handle 2 are made of plastic; more preferably, both the fan blades 1 and the fan handle 2 are made of PP material. This makes the folding fan low in manufacturing cost, lightweight, long in service life, and waterproof.

[0043] The folding fan in this embodiment is equipped with a connector 3. The connector 3 connects the fan blades 1 together, limiting the opening and closing degree of the folding fan and ensuring its effectiveness in use. It provides a good heat-relieving effect. At the same time, the manufacturing process is simple and the manufacturing cost is low. In addition, the connector 3 is made of plastic or ribbon, which are widely available, further reducing the manufacturing cost of the folding fan. The stable chemical properties of plastic make it have excellent durability and corrosion resistance, effectively resisting the erosion of natural environments such as oxygen, moisture and ultraviolet rays, as well as physical damage such as tearing or impact. This means that connectors made of plastic are not easily damaged after long-term use, thus ensuring the service life of the folding fan. Ribbon is usually made of high-strength, wear-resistant materials, with good durability and anti-aging properties. At the same time, ribbon also has a certain drape, so when the fan blades are folded and closed, it will not affect the appearance of the folding fan or increase the space occupied by the folding fan, making it more durable and convenient.

[0044] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
