[0023] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways.

Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0024] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0025] A flow guide structure according to an embodiment of the present application, such as Figure 1 As shown, it includes a membrane layer 1, a plurality of bone pieces 2 and a central axis 3. The number of the bone pieces 2 is not limited and can be set according to user needs.

[0026] The membrane layer 1 includes a plurality of foldable folding units 11 connected in sequence, wherein the folding unit 11 includes a fixing area 111 and a folding area 112. After the plurality of folding units 11 are connected in sequence, two folding areas 112 are arranged between two fixing areas 111. The membrane layer 1 plays a major role in guiding flow in the guiding structure. The fixing area 111 is relatively stable and is used to install the bone piece 2.

[0027] The multiple folding units 11 can be folded, the fixed area 111 and the folding area 112 of one folding unit 11 can be folded, and the two folding areas 112 can also be folded, so the shape of the flow-guiding structure can be changed. In addition, the multiple folding units 11 are provided to extend the flow-guiding path of the fluid, so that the fluid and the flow-guiding structure can fully interact with each other.

[0028] The plurality of bone pieces 2 are respectively arranged on the fixing area 111 . The bone pieces 2 can provide certain support and strength for the flow guiding structure, and help to maintain the shape of the flow guiding structure.

[0029] The central axis 3 passes through the fixing area 111, the folding area 112 and the bone piece 2. Figure 2 As shown, when the fixing area 111 and the folding area 112 overlap, the flow guiding structure is in the first state, as shown in FIG. Figure 1 As shown, when the fixing area 111 and the folding area 112 are staggered, the guide structure is in the second state.

[0030] The guide structure is in a first state, that is, not in use, and is stored, and is in a strip-shaped structure as a whole. The guide structure is in a second state, that is, in use, and is used for guiding, and is in a spiral structure as a whole, and forms a spiral surface.

[0031] The fixing area 111, the folding area 112 and the bone piece 2 can all rotate around the central axis 3 so that the diversion structure can switch between the first state and the second state. This switching can be manually operated or automatically switched by mechanical devices or other means. If the application is in a relatively stable environment, the friction between the folding units 11 can be directly relied on to maintain the current shape after switching.

[0032] In this embodiment, a central axis series hole 33 is left at the center position of the fixing area 111, the folding area 112 and the bone piece 2. The central axis 3 can connect in series the multiple folding units 11 after folding (that is, the guide structure is in the first state), so that all the folding units 11 can rotate around the central axis 3 without falling off easily.

[0033] like Figure 4 As shown, exemplarily, in this embodiment, eight folding units 11 are provided, wherein the last folding unit 11 only includes a fixing area 111 .

[0034] All adjacent folding units 11 can be stacked, and the folding unit 11 includes a first side and a second side opposite to each other, wherein the first side is the edge of the fixing area 111, and the second side is the edge of the second folding area 112. The stacking method is that the second side of the first folding unit 11 is connected to the first side of the second folding unit 11, and so on. The total number of all fixing areas 111 and folding areas 112 is 3c+1, where c is an integer >1.

[0035] Specifically, Figure 4 As shown, the connection order of the multiple folding units 11 is: a fixed area 111 of the first folding unit 11 is followed by two folding areas 112 in sequence, and then the last folding area 112 of the first folding unit 11 is connected to the fixed area 111 of the second folding unit 11, and a fixed area 111 of the second folding unit 11 is followed by two folding areas 112 in sequence, and this is repeated until the last folding unit 11 is connected (i.e., there is only one fixed area).

[0036] Assuming that the multiple folding units 11 are a, b, c...n, after the multiple folding units 11 are connected, they form a fixed area a-folding area a1-folding area a2-fixed area b-folding area b1-folding area b2...fixed area n-folding area n1-folding area n2 which are connected in sequence, a fold is formed between the fixed area a and the folding area a1, a fold is formed between the folding area a1 and the folding area a2, and the directions of the two folds are opposite.

[0037] Furthermore, the fold formed between the folding area a2 and the fixed area b has the same direction as the first fold, the fold formed between the fixed area b and the folding area b1 has the same direction as the second fold, and the other folds are formed in the same manner.

[0038] according to Figure 4 In the order from top to bottom, the fixed area 111 of the uppermost folding unit 11 remains stationary, and all other folding units 11 rotate and unfold around the central axis 3 along the first direction (clockwise or counterclockwise). After unfolding, they present a spiral structure and form a spiral surface. At this time, the application is in the second state.

[0039] On the contrary, the fixed area 111 of the uppermost folding unit 11 remains stationary, and all other folding units 11 rotate and fold around the central axis 3 in the second direction, and the folded ...

[0040] Furthermore, when the flow guiding structure is rotated and unfolded into the second state, as shown in FIG. Figure 3 As shown, there is at least one complete spiral layer (having a circular profile as a whole when viewed in the axial direction of the central axis 3 toward the present application).

[0041] Assume that the sum of the number of fixed areas 111 and the number of folding areas 112 is 3c+1, c is an integer ≥ 1, each fixed area 111 and the folding area 112 have the same shape and area, which is a rectangle with a width of a and a length of b, the length of the sides of the bone piece 2 is d, and the perimeter of the circular outline is approximately L, ; There are c+1 fixed areas 111, and the sum of the lengths of the two outer spiral sides of the unfolded spiral structure is l. ; To fully expand the spiral to have at least one complete spiral surface, the following conditions must be met: ;

[0042] ;

[0043] In this embodiment, the bone piece 2 is a hard material, the membrane layer 1 is a flexible material (such as waterproof cloth), and the combination of the bone piece 2 and the membrane layer 1 is a stacking of hard materials and flexible materials. Therefore, when unfolded, folds or grooves will be formed between adjacent fixed areas 111 and folding areas 112 (or two adjacent folding areas 112), which is conducive to guiding the fluid in the folds or grooves to the edge of the membrane layer 1.

[0044] In one embodiment, if Figure 4A gasket 6 made of elastic material (such as rubber, plastic, etc.) is arranged between the central axis series hole 33 of the uppermost fixing area 111 and the central axis 3. The elastic material can seal the gap between the central axis 3 and the central axis series hole 33, thereby preventing liquid from penetrating from the central axis series hole 33 and affecting use.

[0045] In another embodiment, when the present application is applied to an umbrella structure, a handle needs to be provided at the bottom of the guide structure. Under the premise of not affecting the opening and closing of the guide structure, the handle can be integrated with the central axis 3 to prevent rainwater leakage, and a sealing ring is not required between the central axis 3 at the top of the guide structure and the central axis series hole 33.

[0046] In one embodiment, if Figure 1 As shown, the membrane layer 1 is provided with two layers, a first interlayer is formed between the two membrane layers 1, and the bone piece 2 is provided in the first interlayer.

[0047] In this embodiment, the membrane layer 1 is configured as two layers, and the two membrane layers 1 are stacked and fit together at the edges. The bone piece 2 is a long thin sheet structure, with one wide side of the membrane layer 1 as the starting point and the other wide side as the end point. A bone piece 2 is placed at a certain distance (the direction of the strip bone piece 2 is parallel to the wide side of the rectangular membrane layer 1, and the sheet surface is in contact with the membrane layer 1) until all the bone pieces 2 are evenly placed and fixed on the membrane layer 1 to prevent relative sliding or leakage.

[0048] In one embodiment, the bone slices 2 are provided in two layers, a second interlayer is formed between the two layers of the bone slices 2, and the membrane layer 1 is provided in the second interlayer.

[0049] In this embodiment, when the membrane layer 1 is a single-layer structure, by providing two layers of bone pieces 2, the upper and lower layers of bone pieces 2 can be tightly attached to the membrane layer 1 sandwiched in the middle to prevent relative sliding between the bone pieces 2 and the membrane layer 1, thereby forming a fixed area 111.

[0050] In another embodiment, the bone piece 2 is provided as a single layer, the membrane layer 1 is provided as a single layer, and the bone piece 2 is directly connected to the membrane layer 1 .

[0051] When the membrane layer 1 is connected to the bone piece 2 , the edge of the bone piece 2 is fixed at a fixed position on the membrane layer 1 by suturing, bonding or other techniques to prevent relative sliding between the bone piece 2 and the membrane layer 1 , thereby forming a fixed area 111 .

[0052] In one embodiment, if Figure 7 As shown, the bone piece 2 is a spindle-shaped structure, and its center is concentric with the center of the central axis 3. When the bone piece 2 is a spindle-shaped structure, the utilization rate of the membrane layer 1 can be improved, so that the rotation angle of the spiral of the present application is larger when it is unfolded. Figure 4In addition to the central axis series holes 33 on the uppermost and lowermost bone pieces 2 shown, crown-shaped buckle holes are also provided on both ends of the bone piece 2 for fixing with the exoskeleton 5 described below.

[0053] In another embodiment, if Figure 9-11 As shown, one end of the bone piece 2 forms a bent positioning portion 21, and the bent portion does not affect the stacking effect of the bone piece 2. Any one end or both ends of the bone piece 2 are slightly bent or deflected to form a certain inclined surface.

[0054] Since both ends of the bone piece 2 have a certain degree of rotation, the present application can only be unfolded in the same direction. However, when the present application is folded, the probability of each component returning to its correct position is significantly improved.

[0055] In yet another embodiment, Figure 5 As shown, when the bone piece 2 is closer to a rectangular structure, the return rate of the membrane layer 1 when folded and contracted can be improved, making the whole after folding more regular. In addition, the outer edge of the bone piece 2 is provided with a rounded corner, which can reduce the loss of the membrane layer 1.

[0056] The bone piece 2 can be replaced according to actual usage. The bone piece 2 includes a sheet structure with higher hardness and a sheet structure with lower hardness. When it is necessary to spirally unfold and continuously rotate around the central axis 3 for drainage, the bone piece 2 with higher hardness is replaced. The continuously rotating movement state of the bone piece 2 makes it straighten itself; if the hardness requirement for the bone piece 2 is not very high, the bone piece 2 with lower hardness or part of the bone piece with lower hardness can be replaced.

[0057] In one embodiment, if Figure 6 As shown, the central axis 3 includes a first axis tube 31 and a second axis tube 32 movably connected to the first axis tube 31 , and the first axis tube 31 and the second axis tube 32 pass through the folding unit 11 .

[0058] In this embodiment, the second shaft tube 32 is sleeved inside the first shaft tube 31, and the opposite ends of the first shaft tube 31 and the second shaft tube 32 are all closed structures. The central axis 3 is a columnar body formed by the first shaft tube 31 and the second shaft tube 32 being sleeved and fastened together. The central axis 3 connects all the folding units 11 in series along the central axis series hole 33 in the center of all the folding units 11, so that all the folding units 11 can rotate around the central axis 3 and are constrained on the central axis 3 and do not fall off easily.

[0059] In one embodiment, the guide structure further includes a fixing component, and the fixing component is disposed on the central axis 3 or the film layer 1 so that the folding units 11 in the second state can be brought closer to each other.

[0060] In this embodiment, when the fixing component is the first magnet 41 and the second magnet 42 that are attracted to each other, magnets are placed inside the first shaft tube 31 and the second shaft tube 32, and the first shaft tube 31 and the second shaft tube 32 are respectively provided with the first magnet 41 and the second magnet 42. The first magnet 41 and the second magnet 42 attract each other to cause the central axis 3 to clamp all the folding units, so that the multiple folding units 11 will not loosen and fall off during the opening and closing process.

[0061] When the fixing components are thread grooves and thread protrusions, the first shaft tube 31 and the second shaft tube 32 can be connected by threads. The inner wall of the first shaft tube 31 is provided with a thread groove, and the outer wall of the second shaft tube 32 is provided with a thread protrusion adapted to the thread groove. Through the cooperation of the thread groove and the thread protrusion, the second shaft tube 32 is screwed into the interior of the first shaft tube 31 to achieve the effect of clamping all the interlayers.

[0062] When the fixing component is a slot and a buckle, a slot is set deep in the inner wall of the first shaft tube 31, and a protrusion adapted to the slot is set at the outer wall port of the second shaft tube 32. This facilitates the insertion of the second shaft tube 32 into the first shaft tube 31, and the effect of clamping all the interlayers is achieved through the cooperation of the slot and the protrusion.

[0063] In another embodiment, a storage component is further included, and the storage component is used to store the diversion structure in the first state. The storage component includes a tightening rope, Velcro, etc. After being folded into a long strip, the present application is convenient to fold and store, and saves space. The tightening rope is used to wrap and tighten all the folding units 11 to prevent the folding units 11 from automatically unfolding, so as to facilitate their storage and storage.

[0064] In another embodiment, when the fixing components are the first magnet 41 and the second magnet 42, since the first magnet 41 and the second magnet 42 can be attracted to each other, when the flow guide structure is in the second state, the first magnet 41 and the second magnet 42 can also fix the flow guide structure in the second state, so that each folding unit 11 is closely arranged and can be clamped together.

[0065] When the guide structure changes between the first state and the second state, in addition to overcoming air resistance and elastic force of material deformation, it is also necessary to overcome friction resistance between each folding unit 11 and overcome the adsorption force between the first magnet 41 and the second magnet 42.

[0066] In one embodiment, if Figure 5 As shown, the membrane layer 1 forms a first surface after being folded, and an exoskeleton 5 is provided on the first surface, and the shape of the exoskeleton 5 matches the shape of the fixing area 111 .

[0067] In this embodiment, if Figure 4The side of the uppermost fixing area 111 is the front side, buckles are provided at both ends of the exoskeleton 5, buckle holes are provided on the fixing area 111 on the front side, the buckles and the buckle holes are engaged with each other, and the exoskeleton 5 is bound to the fixing area 111. A gasket 6 is provided at the connection between the buckle and the buckle hole.

[0068] In another embodiment, the membrane layer 1 forms a tail surface opposite to the front surface after folding, and the tail surface is the lowest position of the guide structure. An exoskeleton 5 may also be provided on the tail surface. At this time, the exoskeleton 5 located on the tail surface is provided with hooks, handles, folding brackets and other structures on the side opposite to the fixed area 111. The hooks, handles, folding brackets and other structures are arranged in a handheld shape to facilitate users to carry, hold and other operations.

[0069] In one embodiment, if Figure 8 As shown, the exoskeleton 5 includes a first skeleton 51 and a second skeleton 52 connected to the first skeleton 51 , and the center of the first skeleton 51 is concentric with the axis of the central axis 3 .

[0070] In this embodiment, the exoskeleton 5 includes a first skeleton 51 and two second skeletons 52. The two ends of the first skeleton 51 are respectively connected to the two second skeletons 52 by snaps. A snap is provided at one end of the second skeleton 52 away from the first skeleton 51. The snap can cooperate with the snap hole on the corresponding fixing area 111. The exoskeleton 5 can cover the outermost fixing area 111. The middle part of the first skeleton 51 has a central axis series hole 33, which is convenient for the central axis 3 to fix the exoskeleton 5 and the folding unit 11.

[0071] In another embodiment, the first skeleton 51 and the second skeleton 52 are both provided with a drainage groove 53, and one end of the drainage groove 53 is a slope structure 54. The first skeleton 51 and the second skeleton 52 can be set as an integral structure, which is conducive to improving the drainage effect of the drainage groove 53.

[0072] In this embodiment, when the liquid falls on the guide structure in the second state, it first contacts the uppermost exoskeleton 5 and then flows downward along the spiral surface. During this process, part of the liquid will be directly thrown out from the edge of the spiral surface.

[0073] The drainage grooves 53 on the edges of the first skeleton 51 and the second skeleton 52 can guide the flow of fluid, and the edge of the second skeleton 52 away from the first skeleton 51 is a slope structure 54, which can guide the fluid to be discharged from the middle to the outside. In addition, the slope structure 54 can cover the folded guide structure to protect the bone piece 2.

[0074] In one embodiment, the guide structure further includes a gasket 6 , and the gasket 6 is disposed between adjacent folding units 11 .

[0075] In this embodiment, the gasket 6 is used to help the film layer 1 to set its shape, reduce the wear of the film layer 1, and increase the inclination of the spiral surface when unfolding (by replacing gaskets 6 of different thicknesses). By replacing gaskets 6 of different thicknesses, the distance between the folding units 11 can be affected, so that the inclination of the spiral surface relative to the central axis 3 can be adjusted by the gasket 6.

[0076] Specifically, a gasket 6 of a certain thickness is placed between the folding units 11 and sleeved on the central axis 3 to facilitate adjustment of the distance between the folding units 11. Since the membrane layer 1 is supported by a flexible material, the roughness of its surface and the hardness of the bone piece 2 will affect the friction between the folding units 11, so the appropriate distance between the folding units 11 is beneficial to improving the return rate of the flexible material when folding.

[0077] In the prior art, since the umbrella surface is made of flexible material, a large number of redundant folds will appear on the edge of the umbrella surface when it is folded, so that after folding, there are problems such as occupying a large space and being easily connected or touching other objects. Although the redundant folds of the umbrella surface can be gathered by ropes or other tools, such operations require the arrangement of the ribs and the umbrella surface to be arranged, which requires a certain amount of time and arrangement skills. If the umbrella frame is not gathered or is directly tied with ropes, it is easy to cause deformation of the umbrella frame, and the thin rod-shaped umbrella ribs are also easy to poke into the holes, causing damage to other objects or making it inconvenient to take out the umbrella. The deformation of the umbrella frame and the entrainment of the umbrella surface caused by the misalignment of the ribs and the umbrella surface will shorten the service life of the umbrella.

[0078] Therefore, when applying the diversion structure to an umbrella: As described above, the diversion structure is unfolded to the second state in the present application. At this time, it is used as rain gear, and the user needs to directly hold the handle structure connected to the central axis 3 or the exoskeleton 5.

[0079] When the fluid falls onto the present application, the movement path of the fluid includes: "guiding the fluid along the spiral surface until the fluid is discharged from the end" and "directly guiding the fluid out from the edge of the spiral surface".

[0080] That is, when raindrops touch the rotating and unfolded present invention, the rainwater attached to the folding unit 11 of the present invention will continue to slide down along the spiral surface due to its own inertia, gravity, and the supporting force of the spiral surface. In this process, since the downward sliding requires rotation along the spiral surface, the rainwater will gradually move away from the central axis 3 due to its own inertia during rotation. Therefore, some of the rainwater will be discharged from the edge of the spiral surface.

[0081] When the present invention is unfolded, some folds and grooves will appear on the surface of the spiral folding unit 11, which is conducive to rainwater flowing to the edge of the spiral surface, away from the central axis 3 and discharged. In addition, the flexible material is depressed downward due to the load of rainwater, so that the bone piece 2 is subjected to downward pressure and the two ends are bent downward. These deformations help increase the inclination of the spiral surface, thereby causing rainwater to flow to the edge of the spiral surface, away from the central axis 3 and discharged.

[0082] When used as rain gear in the present application, the drainage groove 53 of the exoskeleton 5 facilitates guiding rainwater to both ends. The drainage groove 53 of the exoskeleton 5 covers the outermost fixed area 111, and the special inclined structure 54 helps to separate rainwater directly from the structure at both ends, thereby preventing rainwater from flowing back to the middle along the outer surface of the exoskeleton 5, causing the rainwater to eventually flow onto the user.

[0083] The present application adopts the method of fixing the central axis 3 and rotating to open and close to fold the folding unit 11, and utilizes the characteristic that friction is affected by pressure to make the joint action of the membrane layer 1 more convenient, effectively eliminating the defects of the pleats occupying a large space and being difficult to fold and organize when the traditional umbrella is folded. The bone piece 2 responsible for opening the membrane layer 1 is set as a sheet structure, which effectively eliminates the safety problem caused by the easy misalignment of the thin rod-shaped umbrella ribs of the traditional umbrella.

[0084] The present application sets the connection methods of various parts to snap-on and magnetic types, so that parts can be replaced without the aid of tools, thereby reducing the cost of repair, increasing the utilization rate of various parts, and being more environmentally friendly.

[0085] When the flow-guiding structure is applied to a pipeline, there are two working modes: the flow-guiding structure actively rotates to discharge the fluid and the flow-guiding structure rotates due to the impact of the fluid.

[0086] ① When the flow-guiding structure actively rotates to discharge fluid, an active force needs to be applied to the flow-guiding structure so that the exoskeleton 5 on one side drives the folding unit 11 to continuously rotate in one direction around the central axis 3 until the flow-guiding structure is in the second state, so as to guide the fluid impacting the flow-guiding structure.

[0087] ② When the guide structure is impacted by the fluid and rotates, the guide structure is in the second state after being unfolded, and always maintains the second state. At this time, the guide structure can rotate as a whole after being impacted by the fluid.

[0088] In this embodiment, the flow-guiding structure can convert the impact force of the liquid into the rotational mechanical energy of the structure itself, that is, the flow-guiding structure in the unfolded state can rotate on its own.

[0089] Among them, the properties of the fluid such as "viscosity", "density" and "impact strength" have certain requirements for the overall structural strength of the present application, including the toughness, hardness, shape of the membrane layer 1 material and the bone piece 2 material, as well as the relative fixation method of the fabric and the bone piece 2; the "roughness" of the fluid particles has certain requirements for the wear resistance of the constituent materials of the present application.

[0090] In another embodiment, when the present application is folded and contracted, the outermost exoskeleton 5 can be set to a shape structure with less fluid resistance (such as an arc surface). At this time, the interaction between the fluid and the present application is greatly weakened, which can be regarded as suspending work, facilitating other operations such as transfer and maintenance.

[0091] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
