Description

Technical Field

[0001] This utility model relates to the field of daily necessities, specifically to a modular fan. Background Technology

[0002] Round fans are often used as advertising tools by businesses and are a convenient way for people to cool off, and they are ubiquitous in summer. Due to the limited fan surface area, their fan efficiency is generally lower than that of larger fans such as banana leaf fans and palm leaf fans. Especially in hot and humid environments, they are unable to quickly form an effective airflow, resulting in insufficient cooling effect. Folding fans mostly use a connection method of "fixing the shaft to the end of the fan handle". In actual use, the fan handle only serves as a connecting carrier at the end of the fan ribs, lacking sufficient grip support. This leads to a shift in the center of gravity when holding the fan, a loose feel, fatigue after prolonged use, and poor control stability when opening and closing.

[0003] In contrast, non-folding fans such as banana leaf fans and palm leaf fans achieve good hand comfort and operational stability through their one-piece long handle design (usually a rigid handle made of bamboo, wood, or plastic). Users can concentrate their force through the end of the long handle, resulting in a wide and even airflow coverage when fanning, making the fan efficiency significantly better than folding fans. However, because these fans have a fixed overall structure, are large in size, and cannot be folded, they are extremely inconvenient to store and carry, making them unsuitable for the needs of modern travel scenarios.

[0004] Therefore, how to improve the fan's efficiency, enhance its hand comfort, and ensure its ease of storage while retaining its portability has become a pressing technical problem in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a round fan to solve the problems of low fan efficiency, poor hand comfort, and inconvenient storage of existing round fans, palm leaf fans, and banana leaf fans.

[0006] To achieve the above objectives, this utility model provides a modular fan, which includes a first fixed fan blade and a movable fan blade, with the movable fan blade disposed on one side of the first fixed fan blade. The first fixed fan blade includes a first fan surface and a first fan handle, with the first fan surface and the first fan handle being integrated. A first through hole is provided on the first fan surface, located on the side of the first fan surface near the first fan handle. The movable fan blade includes only a second fan surface, with a second through hole provided on the second fan surface. The second through hole and the first through hole are coaxially arranged, and a connector passes through the first through hole and the second through hole to connect the first fixed fan blade and the movable fan blade. The movable fan blade can rotate around the axis of the connector.

[0007] As can be seen from the above solution, the modular fan of this utility model, by setting a first fixed fan blade and a movable fan blade, and the movable fan blade does not have a handle, the user only needs to hold the handle on the fixed fan blade when using it, which is convenient and comfortable to hold. It solves the problem of low holding comfort and inconvenience of force exertion caused by too many fan blades when the existing folding fan is opened. Secondly, the structure of the movable fan blade can rotate freely around the coaxial axis, which not only retains the portable characteristics of the folding fan that can be folded and stored, but also makes the overall area compact when the movable fan blade is folded and fits close to the fixed fan blade. It can also expand the effective fan area by adjusting the angle of the movable fan blade, similar to the flexible effect of adjusting the airflow by rotating the long handle of the banana leaf fan. This significantly improves the fan efficiency and overcomes the problems of the banana leaf fan being difficult to store and the single modular fan having an inability to adjust the size of the fan surface. It achieves the combined advantages of portability, efficient cooling, and comfortable grip with a long handle.

[0008] A further option is that the cluster fan also includes a second fixed fan blade, which is arranged opposite to the first fixed fan blade, and a movable fan blade is arranged between the first and second fixed fan blades.

[0009] As can be seen from the above scheme, the addition of a second fixed fan blade opposite to the first fixed fan blade and the movable fan blade in the center forms a symmetrical support structure, which not only enhances the overall strength when unfolded and prevents the fan surface from shaking; the double-sided fixed fan handle provides more balanced grip support and makes the grip more stable, the movable fan blade in the center folds more compactly, and the fixed fan blades on both sides can also protect it from external wear and tear, improving the durability of the group fan.

[0010] A further embodiment is that the second fixed fan blade includes a third fan surface and a third fan handle, the third fan surface and the third fan handle are connected as one piece, a third through hole is provided on the third fan surface, the third through hole is provided on the side of the third fan surface near the third fan handle, the third through hole is coaxially arranged with the first through hole, and the connector passes through the third through hole.

[0011] As can be seen from the above scheme, the second fixed fan blade is provided with a third through hole coaxial with the first through hole. After the connecting piece passes through, the movable fan blade is constrained by the coaxiality of the two fixed fan blades, making the rotation more stable.

[0012] A further option is to have two movable fan blades, which can rotate close to or far from each other with the axis of the connecting piece as the center.

[0013] As can be seen from the above scheme, the setting of two movable fan blades allows for a wider range of adjustment of the fan area, adapting to different fan needs of users.

[0014] A further design involves having curved sides on the movable fan blades, with the curved sides of the two movable fan blades positioned far apart from each other.

[0015] As can be seen from the above scheme, the movable fan blades have arc-shaped sides, which can guide the airflow to be concentrated and discharged along the arc surface, thereby improving the fan efficiency. The two arc-shaped sides are far apart from each other, so they can be retracted into the fixed fan surface for smoother storage. When unfolded, the sweeping range is expanded, the air outlet is enlarged, and the airflow output is enhanced.

[0016] A further design is to provide a fourth through hole on the first fan handle, with the fourth through hole located on the side of the first fan handle away from the first fan surface.

[0017] As can be seen from the above scheme, the fourth through hole can be used to set up decorative items such as pendants and tassels, and it is also convenient to hang the fan to improve its aesthetics.

[0018] A further option is to provide a fixing member at one end of the connector, which can move along the axial direction of the connector.

[0019] As can be seen from the above scheme, the fixing component is used to lock the movable fan blade and the fixed fan blade, so that the movable fan blade can rotate to any angle and form a fan area of ​​any size.

[0020] A further option is to use a screw cap (bolt) as the connector and a nut as the fastener.

[0021] As can be seen from the above solutions, the parts are widely available, have a simple structure, low cost, and good locking stability.

[0022] A further embodiment is that the first fan surface includes a first plastic fan rib and a first sticker layer covering both sides of the first plastic fan rib, the first plastic fan rib being arranged radially.

[0023] A further embodiment is that the second fan surface includes a second plastic fan rib and a second sticker layer covering both sides of the second plastic fan rib, with the second plastic fan rib arranged radially.

[0024] As can be seen from the above scheme, the addition of fan ribs increases the structural strength of the fan surface and ensures the service life of the round fan. Attached Figure Description

[0032] The present invention will be further described below with reference to specific embodiments. Detailed Implementation

[0033] See Figures 1 to 7 In this embodiment, the group fan includes a first fixed fan blade 11, two movable fan blades 2, and a second fixed fan blade 12. The second fixed fan blade 12 is disposed opposite to the first fixed fan blade 11, and the two movable fan blades 2 are disposed between the first fixed fan blade 11 and the second fixed fan blade 12.

[0034] The first fixed fan blade 11 includes a first fan surface 111 and a first fan handle 113. The first fan surface 111 is connected to the first fan handle 113. A first through hole 112 is provided on the first fan surface 111, located on the side of the first fan surface 111 closest to the first fan handle 113. A fourth through hole 114 is provided on the side of the first fan handle 113 furthest from the first fan surface 111. The fourth through hole 114 can be used to attach decorative items such as pendants or tassels, enhancing the aesthetics of the fan assembly. The first fan handle 113 is nearly rectangular.

[0035] The first fan surface 111 includes a plurality of first plastic fan ribs 115 extending along the length direction of the first fan surface 111, and a first sticker layer covering both sides of the first plastic fan ribs 115. The first sticker layer is an adhesive sticker, which is pasted on both sides of the first plastic fan ribs 115 to form the first fan surface 111. The first plastic fan ribs 115 are arranged radially. The plurality of first plastic fan ribs 115 are connected by first horizontal fan ribs 116 to improve the structural strength of the first fan surface 111.

[0036] The second fixed fan blade 12 has a basically the same structure as the first fixed fan blade 11. Specifically, the second fixed fan blade 12 includes a third fan surface and a third fan handle. The third fan surface is connected to the third fan handle. A third through hole is provided on the third fan surface, which is located on the side of the third fan surface near the third fan handle. The third fan handle is nearly rectangular.

[0037] The movable fan blade 2 includes only the second fan surface 21, and the second fan surface 21 is provided with a second through hole 211.

[0038] The first through hole 113, the second through hole 211, and the third through hole are coaxially arranged. The connector 31 passes through the first through hole 113, the second through hole 121, and the third through hole to connect the first fixed fan blade, the movable fan blade 2, and the second fixed fan blade 12. The movable fan blade 2 can rotate around the axis of the connector 31. Specifically, the two movable fan blades 2 can rotate closer to or further away from each other around the axis of the connector 31. The movable fan blade 2 is provided with an arc-shaped side 22, and the arc-shaped side 22 of the two movable fan blades 2 are arranged far apart from each other. The second fan surface 21 includes a plurality of second plastic fan ribs 212 extending along the length direction of the second fan surface 21, and a second sticker layer covering both sides of the second plastic fan ribs 212. The second sticker layer is an adhesive sticker, which is pasted on both sides of the second plastic fan ribs 212 to form the second fan surface 21. The second plastic fan ribs 212 are arranged radially, and the plurality of second plastic fan ribs 212 are connected by second horizontal fan ribs 213 to improve the structural strength of the second fan surface 21.

[0039] One end of the connector 31 is provided with a fixing member 32, which can move along the axial direction of the connector 31. In this embodiment, the connector 31 is a bolt and the fixing member 32 is a nut.

[0040] When stored normally, the two movable fan blades 2 rotate to their closest possible position and are locked in place by the connector 31 and the fixing piece 32, minimizing the overall fan assembly area and facilitating storage. When in use, rotating the fixing piece 32 creates a gap between the movable fan blade 2 and the first fixed fan blade 11 and the second fixed fan blade 12, allowing the movable fan blade 2 to rotate. Figure 4 As shown in the figure, this is a structural schematic diagram of the movable fan blade 2 opening to a certain angle. When the movable fan blade 2 rotates to the required angle, the angle can be fixed by rotating the fixing part 32. When the movable fan blade 2 rotates open in a disjointed motion, the entire fan area of ​​the folding fan is arc-shaped, similar to a palm leaf fan.

[0041] This embodiment of the group fan features fixed and movable blades. The movable blades do not have a handle, so the user only needs to hold the handle on the fixed blade, making it convenient and comfortable to hold. This solves the problem of low grip comfort and inconvenience in exerting force caused by the excessive handle of existing folding fans when they are opened. Secondly, the movable blades can rotate freely around a coaxial axis, which retains the portable characteristics of folding fans. When folded, the movable blades fit snugly against the fixed blades, resulting in a compact overall size. At the same time, the effective fan area can be expanded by adjusting the angle of the movable blades, similar to the flexible effect of adjusting airflow by rotating the long handle of a banana leaf fan. This significantly improves the fan efficiency and overcomes the difficulties in storing banana leaf fans and the inconvenience of holding folding fans. It achieves the combined advantages of portability, efficient cooling, and comfortable grip with a long handle.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
