Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a sun-protective folding fan. Background Technology

[0002] A folding fan is a type of fan with bamboo or wood ribs, used for daily cooling. Traditional fans with surfaces made of tough paper or silk are easily damaged due to the material's poor abrasion resistance and tear resistance (e.g., repeated opening and closing of the folding fan can cause the fibers at the folds to gradually break due to fatigue, or scratches from external objects can cause holes or fraying). Furthermore, traditional folding fans only provide cooling; however, in hot weather, people often carry both a sun umbrella and a fan, making it inconvenient to carry multiple items.

[0003] Therefore, a dual-purpose sun-protective folding fan is specially provided. The detachable fan handle and the unfoldable and rollable fan ribs combine to form both a fan and a sun umbrella. This allows the folding fan to have both the function of fanning and the function of shading and cooling. It also combines the folding and storage function of traditional folding fans with the telescopic storage function of sun umbrellas. It is a two-in-one product that is convenient to use and carry.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1, such as Figures 1-5 As shown, a sun-protective folding fan includes a sun-protective fan surface 1, a detachable fan handle 2, a first fan rib 3, and several second fan ribs 4. The first fan rib 3 is adhered to the back of the sun-protective fan surface 1 along its horizontal center line. Several second fan ribs 4 are symmetrically and evenly adhered to the back of the sun-protective fan surface 1, above and below the first fan rib 3, forming a fan as shown in the image. Figure 1 and Figure 2 , Figure 5 The fan-shaped main body shown can be flattened and rolled up; as shown Figure 1 and Figure 3 As shown, the detachable fan handle 2 is horizontally fitted onto the fan body, and the middle section of the detachable fan handle 2 is connected to the center point of the fan body by rivets 5, forming an assembly as shown. Figure 1 and Figure 2 The sun-protecting folding fan shown is used for daily fanning and cooling.

[0026] Furthermore, such as Figure 3 As shown, the detachable fan 2 consists of a first connecting rod 201, a middle support rod 202, and a tail handle 203; the first connecting rod 201 of the detachable fan handle 2 is threadedly connected to the other end of the rivet 5, and the tail handle 203 of the detachable fan handle 2 is threadedly connected to the other end of the first connecting rod 201 of the detachable fan handle 2, forming an assembly as shown in the figure. Figure 5 The sun umbrella shown is used for everyday use to provide shade from the sun.

[0027] In addition, it should be noted that during the production process, such as Figure 2 As shown, a limiting block is adhered to the front of the fan body. The limiting block is located near the right side of the detachable fan handle 2 and at the edge of the fan body, used to limit the rotation angle of the fan body; as shown Figure 5 As shown, the limiting block is I-shaped, and an elastic pull cord is fitted onto the limiting block. An elastic sheet is attached to the other end of the elastic cord. One side of the elastic sheet has a Velcro loop, and the other side has a Velcro hook, forming an elastic fixing cord used when the sun-protective folding fan is bent or rolled up. Figure 4 When the fan is in the folded state, the elastic fixing cord is wrapped around the outer wall of the folded fan to make the hook and loop sides of the Velcro adhere together, so that the folded fan can be stably kept in the folded state.

[0028] Furthermore, in the embodiments, such as Figure 1 and Figure 2 As shown in the sun-protective folding fan configuration, the bottom of the first connecting rod 201 is threadedly connected to the top of the middle support rod 202, and the tail of the middle support rod 202 is threadedly connected to the top of the inner rod in the tail handle 203. The detachable fan handle and the unfoldable and retractable fan ribs combine to form either a fan or a sun umbrella. Combined with the retractable fan handle at the tail end, this sun-protective folding fan integrates the folding and storage functions of a traditional folding fan and the retractable storage functions of a sun umbrella. Furthermore, it provides both fanning and sun-shading cooling properties, effectively solving the problem of the single function of traditional folding fans, making it convenient to use and carry.

[0029] Furthermore, such as Figure 1 and Figure 3 As shown, a transverse strip-shaped groove is provided on the middle section support rod 202, and a fan-shaped main body is inserted into the strip-shaped groove of the middle section support rod 202; as Figure 1 and Figure 2 , Figure 3 As shown, the shank of the rivet 5 passes through the rear side of the middle support rod 202, the fan-shaped main body, and the front side of the middle support rod 202 from back to front.

[0030] Furthermore, it should be noted that after rivet 5 is installed on the folding fan, the end of the rivet shank is upset to form an upset head (e.g., Figure 1 and Figure 3 (As shown), so as to clamp the middle support rod.

[0031] Furthermore, such as Figure 1 and Figure 3 , Figure 4 As shown, the head of the rivet 5 and the top of the middle support rod 202 are respectively drilled with a first internal thread groove 6; the top of the first connecting rod 201 and the bottom of the middle support rod 202 are respectively drilled with a second internal thread groove 7; as shown Figure 3 As shown, the first connecting rod 201 is T-shaped, and the bottom outer wall of the first connecting rod 201 is provided with an external thread that cooperates with the first internal thread groove 6; the top outer wall of the inner rod of the tail handle 203 is provided with an external thread that cooperates with the second internal thread groove 7.

[0032] Preferably, the outer diameter of the rivet head of the rivet 5 is smaller than the outer diameter of the middle support rod 202; the diameter of the first internal thread groove 6 is smaller than the diameter of the second internal thread groove 7; such as Figure 3As shown, the tail section handle 203 is a spring telescopic rod. The diameter of the inner rod of the tail section handle 203 is smaller than the outer diameter of the middle support rod 202 and larger than the diameter of the second internal thread groove 7. The outer diameter of the outer rod of the tail section handle 203 is greater than or equal to the diameter of the middle support rod 202, and the inner diameter of the outer rod of the tail section handle 203 is slightly larger than the diameter of the inner rod.

[0033] In this embodiment, the spring telescopic rod is an existing structure, with the inner rod inserted into the outer rod. The outer rod has several locking holes evenly distributed from top to bottom. The inner rod is composed of a long rod connected to a short rod by a spring (the two ends of the spring are welded to the bottom surface of the long rod and the top surface of the short rod, respectively). The short rod is provided with a spring locking block that engages with the locking holes, so that the inner rod can slide inside the outer frame to achieve the telescopic function. The specific details will not be described in detail in this embodiment.

[0034] In this embodiment, according to Figure 1 and Figure 2 The diameter of the fan surface in the flat state can be set to at least 40cm to achieve the effect of a sun umbrella. The head size of the rivet 5 can be set to a diameter of 1.5cm and a length of 2cm. The diameter of the first internal thread groove 6 can be set to 0.5-1.0cm. The diameter of the middle support rod 202 can be set to 2.5cm. The diameter of the second internal thread groove 7 can be set to 0.8-1.5cm. In other embodiments, the dimensions can be adjusted adaptively according to actual needs, which will not be described in detail here.

[0035] Furthermore, such as Figure 3 As shown, a thin metal tube 8 is embedded in the central hole of the fan body; the thin metal tube 8 is fitted onto the rod of the rivet 5, and the diameter of the rivet rod is slightly smaller than the inner diameter of the thin metal tube 8, so that the fan body can rotate to the left or right.

[0036] Furthermore, the sun-protective fan surface 2 is made of waterproof fabric with a sun-protective coating, which is not easily damaged and also has waterproof and sun-protective functions. This can solve the problem of poor durability of traditional folding fans with tough paper or silk fan surfaces. At the same time, the use of waterproof fabric on the fan surface also makes the folding fan have a rain-proof function.

[0037] Furthermore, such as Figure 1 As shown, the width of the first fan rib 3 is greater than the width of the second fan rib 4, which facilitates drilling holes in the fan body.

[0038] It should be noted that the detachable fan handle, the first fan rib, and the second fan rib are all made of, but not limited to, the main material. Bamboo (especially common bamboo and wood) has a natural cost advantage in raw materials and processing. In addition, bamboo is lightweight, tough, and easy to process, so production costs are controllable.

[0039] During installation, care should be taken to leave a gap between the upper and lower fan ribs to facilitate the bending and storage of the fan body. During manufacturing, the first fan rib 3 and the second fan rib 4 need to be cut along the outer contour of the sun-protective fan surface 1. In this embodiment, the sun-protective fan surface 1 is set as a circle, but in other embodiments, the shape of the sun-protective fan surface 1 is not limited to a circle. The specific details will not be described in detail here.

[0040] When the main body of the fan is as follows Figure 1 When the fan is in its unfolded state, the elastic fixing rope is wrapped around the middle support rod to prevent the fan body from rotating to the left or right, thus ensuring that the folding fan remains stably in this unfolded state. The specific usage method is as follows:

[0041] (1) Sunscreen folding fan form: The user can press the spring block and pull down the outer rod to extend the tail handle, making it easier for the user to hold and shake the folding fan to cool off;

[0042] (2) Sunshade Umbrella Configuration: First, the user rotates the first connecting rod 201 to remove it from the top of the middle support rod 202. Then, the user aligns the bottom rod of the first connecting rod 201 with the first internal threaded hole 6 on the nail head and rotates the first connecting rod 201 to connect it to the back of the folding fan. Next, the user rotates the tail handle 203 to remove it from the bottom of the middle support rod 202. Then, the user aligns the inner rod of the tail handle 203 with the second internal threaded hole 7 at the top of the first connecting rod 201 and rotates the tail handle 203 to connect it to the first connecting rod 201. The umbrella is then assembled as shown in the image. Figure 5 The sun umbrella shown has the front of the fan body facing up and the back facing down; the fan ribs are attached to the sun-protective coating on the fan surface. When the user holds the handle 203 at the end and raises the fan body, the fan body covers their head, thus achieving the sunshade function. Because it uses, but is not limited to, nylon waterproof fabric, it can also be used as a temporary umbrella when it rains. In addition, nylon is strong and wear-resistant, which can effectively improve the service life of the folding fan.

[0043] (3) Storage state: At this time, the first connecting rod 201 is installed on the top of the middle support rod 202, and the tail handle 203 is installed on the bottom of the middle support rod 202. Pull the elastic fixing rope forcefully, and then rotate counterclockwise (for...). Figure 2 (As shown) The fan body is at a 90° angle, at which point the fan ribs and the detachable fan handle are parallel. The user bends the fan body counterclockwise and rotates the fan handle, causing the fan to move as shown. Figure 1 The unfolded state is rolled up like Figure 4 The coiled state is shown in the diagram, and then the elastic retaining cord is wound around as shown. Figure 4 The fan can be folded up by placing it on the outer ring of the folding fan as shown. If the tail handle 203 is in the extended state, the spring latch can be pressed and the outer rod pushed upward to reset the tail handle 203. The operation is simple and convenient to carry.
