[0002] Folding umbrellas are a frequently used rain protection tool, effectively blocking rainwater and keeping you dry on rainy days. When not in use, they can be folded up for storage, making them compact, space-saving, and highly portable. However, when folding umbrellas are put away after use, residual rainwater continues to drip from the canopy, which can easily wet the ground, making it slippery, and may also soil clothes, backpacks, or car seats, causing practical inconvenience to users.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a drip-proof device for folding umbrellas and a folding umbrella, which aims to solve the problem that rainwater drips from the surface of the folding umbrella after it is folded up.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: A drip-proof device for a folding umbrella, comprising: Two arc-shaped groove plates are respectively rotatably mounted on the umbrella support and are arranged symmetrically. A receiving groove is provided on the arc-shaped groove plate; the two arc-shaped groove plates can rotate towards or away from each other to close or separate the two receiving grooves to form a receiving cavity to wrap around the umbrella or the exposed umbrella; A locking component, disposed on the arc-shaped groove plate, is used to lock or unlock the two arc-shaped groove plates.

[0006] Furthermore, the arc-shaped groove plate includes: Curved plate; A hinge is provided at the bottom of the arc-shaped plate; the end of the hinge away from the arc-shaped plate is rotatably engaged with the umbrella support. A sealing plate is disposed on the top of the arc-shaped plate to cover the top opening of the arc-shaped plate.

[0007] Furthermore, both the sidewall of the arc-shaped plate and the sidewall of the sealing plate are provided with sealing strips.

[0008] Furthermore, the locking component includes: Multiple magnet blocks are respectively disposed in the two arc-shaped plates and / or the two sealing plates. The magnet blocks in the two arc-shaped plates correspond to each other and attract each other, and the magnet blocks in the two sealing plates correspond to each other and attract each other.

[0009] Furthermore, the locking component also includes: Buckles and slots are respectively provided on the two sealing plates; the buckles and slots engage with each other so that the two sealing plates abut against each other.

[0010] Furthermore, the sealing plate has a water storage cavity inside, and a water inlet is provided on the side of the sealing plate near the receiving groove, which is connected to the water storage cavity; a drain outlet is provided on the side of the sealing plate away from the receiving groove, and a plug is provided in the drain outlet.

[0011] Furthermore, a one-way valve is installed inside the water inlet.

[0012] Furthermore, the arc-shaped groove plate is a plastic arc-shaped groove plate.

[0013] Furthermore, a sealing gasket is provided at the end of the receiving groove away from the sealing plate, and when the two arc-shaped plates are closed, the sealing gasket abuts against the umbrella support.

[0014] A folding umbrella includes the aforementioned drip-proof device for folding umbrellas.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In view of the shortcomings of the prior art, this embodiment provides a drip-proof device for a folding umbrella and a folding umbrella, as detailed below: As attached Figure 1 and attached Figure 4As shown, a drip-proof device for a folding umbrella includes two arc-shaped grooves 1, a receiving groove 2, and a locking assembly. The two arc-shaped grooves 1 are respectively mounted on the umbrella support 6 via a rotating connection structure and are symmetrically arranged along the central axis of the umbrella support 6. The receiving groove 2 is located on the inner wall of the arc-shaped groove 1, with its opening facing the center of the umbrella when not in use and facing away from the center when in use. The two arc-shaped grooves 1 can rotate towards or away from each other around the rotating connection structure. When rotating towards each other to the closed state, the openings of the two receiving grooves 2 align with each other, forming a complete receiving cavity; this cavity can completely cover the folded umbrella canopy 5. When rotating away from each other to the separated state, the receiving cavity opens, exposing the umbrella for normal unfolding and use. The locking assembly is located on the arc-shaped grooves 1 and is used to lock or unlock the two arc-shaped grooves 1.

[0025] The arc-shaped groove plate 1 refers to a plate structure made of waterproof material with a circular arc cross-section. Its curvature matches the outer circumference of the umbrella surface 5 when closed, and its length covers the area of ​​the umbrella surface 5 from the end of the umbrella rib 4 to the umbrella support 6, providing a supporting frame for the receiving groove 2. The receiving groove 2 is a concave space within the arc-shaped groove plate 1, with a smooth arc bottom and a groove wall height not less than the thickness of the umbrella surface 5 when closed, used to collect and store rainwater dripping from the umbrella surface 5. The rotating connection structure refers to the mating component set between the bottom of the arc-shaped groove plate 1 and the umbrella support 6, specifically a hinge or bushing structure, used to realize the rotational opening and closing of the arc-shaped groove plate 1; the locking component can be a combination of multiple magnet blocks or a combination of buckles and slots.

[0026] Specifically, when the umbrella is folded up after use, the user can push the two arc-shaped groove plates 1 to rotate towards each other around the rotating connection structure. As the rotation angle increases, the inner walls of the two arc-shaped groove plates 1 gradually approach the umbrella surface 5 until the openings of the two receiving grooves 2 are completely aligned, forming a closed receiving cavity, which is then locked by the locking component. At this time, the rainwater remaining on the umbrella surface 5 drips down under the action of gravity and falls directly into the receiving groove 2, preventing the rainwater from contacting the ground or surrounding objects. When the umbrella needs to be used again, the user first unlocks the locking component, then pushes the two arc-shaped groove plates 1 to rotate in opposite directions, the receiving cavity separates, and the umbrella can be opened normally.

[0027] Compared to existing technologies, traditional folding umbrellas lack a dedicated water-catching structure, allowing rainwater to drip naturally. Users must manually wipe them or place them in a plastic bag, a cumbersome process prone to leakage. This solution, through a combination of a symmetrical arc-shaped groove plate 1 and a receiving cavity, transforms passive water blocking into active water storage, achieving rainwater collection without additional tools. The rotating design of the arc-shaped groove plate 1 allows the device to flexibly switch according to the umbrella's usage, avoiding space-consuming issues during storage compared to a fixed bag structure.

[0028] Through the above technical solution, this application achieves the anti-drip function of the folding umbrella after use. The cavity can completely catch the rainwater on the umbrella surface 5, preventing rainwater from wetting the ground and causing slipperiness, or soiling clothes, backpacks, and car seats. The symmetrical arrangement and rotational cooperation of the arc-shaped groove plate 1 ensures that the device is easy to open and close, does not affect the portability of the umbrella when folded and stored normally, and eliminates the need to carry additional water-catching accessories, thus improving ease of use.

[0029] In this embodiment, as shown in the appendix Figure 2 As shown, the arc-shaped groove plate 1 includes an arc-shaped plate 11, a hinge 12, and a sealing plate 13. The arc-shaped plate 11 forms the main frame of the arc-shaped groove plate 1, and its inner sidewall is provided with a receiving groove 2 (the receiving groove 2 is the concave space of the arc-shaped groove plate 1). The hinge 12 is fixedly installed on the bottom edge of the arc-shaped plate 11, and the end of the hinge 12 away from the arc-shaped plate 11 is rotatably engaged with the umbrella holder 6 of the umbrella via a pin. The sealing plate 13 is a semi-circular flat plate, fixedly installed on the top edge of the arc-shaped plate 11, used to completely cover the opening at the top of the arc-shaped plate 11 (this opening is the top opening of the receiving groove 2), preventing rainwater from overflowing from the top. The locking assembly can be installed alone on the side of the arc-shaped plate 11, alone on the side of the sealing plate 13, or simultaneously on both sides, depending on the installation requirements, to seal the corresponding sides of the two arc-shaped plates 11 and the two sealing plates 13 when the two arc-shaped groove plates 1 are closed.

[0030] The hinge 12 is a rotating component consisting of two metal or high-strength plastic blades and a pivot pin. The blades are fixed to the bottom of the arc-shaped plate 11 and the umbrella support 6 by screws or adhesive, allowing for flexible rotation within a certain range and ensuring smooth opening and closing of the arc-shaped groove plate 1. The sealing plate 13 is a flat plate of the same material and thickness as the arc-shaped plate 11, with a width sufficient to cover the top opening of the arc-shaped plate 11. It is used to prevent rainwater from leaking from the top of the arc-shaped groove plate 1. The two sealing plates 13, together with the two arc-shaped plates 11, form a receiving cavity. The sealing plates 13 and the arc-shaped plates 11 can be manufactured using an integral injection molding process. The locking component is a component used to fix and seal the two arc-shaped groove plates 1 after they are closed. Its structure must meet the requirements of tight fit when closed and easy separation when open, ensuring the sealing performance of the receiving cavity.

[0031] Specifically, when assembling the arc-shaped groove plate 1, first fix one blade of the hinge 12 to the bottom of the arc-shaped plate 11, and fix the other blade to the corresponding position of the umbrella support 6, and achieve rotational engagement through the connection of the shaft pin; when the two arc-shaped groove plates 1 rotate and close in opposite directions, the user pushes the arc-shaped plate 11 until the sides of the two plates are in contact, at which time the locking component can be manually activated to lock the sides of the two arc-shaped plates 11 and the sides of the two sealing plates 13, forming a gapless sealed engagement state; when it is necessary to open, release the fixing of the locking component, and then push the arc-shaped plates 11 to rotate in opposite directions.

[0032] Through the above technical solutions, the application of the hinge 12 in this application makes the arc-shaped groove plate 1 rotate more smoothly and avoids jamming after long-term use; the sealing plate 13 blocks the top leakage path and further improves the water storage capacity of the cavity; the locking component ensures the structural stability after closure, and even if it shakes during carrying, it will not cause rainwater leakage, thus comprehensively optimizing the use effect of the anti-drip device.

[0033] In this embodiment, sealing strips are provided on the sidewalls of both the arc-shaped plate 11 and the sealing plate 13. The sealing strips are made of elastic waterproof material and are fixedly installed on the sidewalls of the arc-shaped plate 11 and the sealing plate 13 respectively by adhesive bonding or slot embedding. The sealing strip on the sidewall of the arc-shaped plate 11 is arranged along the length direction of the arc-shaped plate 11 and covers the entire sidewall; the sealing strip on the sidewall of the sealing plate 13 is arranged along the width direction of the sealing plate 13 and covers the entire sidewall. It is used to fill the gap between the sidewalls of the two arc-shaped plates 11 and the sidewalls of the two sealing plates 13 when the two arc-shaped groove plates 1 are closed, so as to achieve double sealing.

[0034] The sealing strip is a strip-shaped structure made of rubber or silicone material. Its cross-section is semi-circular or rectangular. It has a certain degree of elasticity and waterproofness. Its width is adapted to the thickness of the arc plate 11 and the sealing plate 13, and its length is consistent with the side length of the arc plate 11 and the sealing plate 13. It can deform under compression to fill gaps.

[0035] Specifically, when the two arc-shaped groove plates 1 rotate towards each other to a closed state, the sides of the two arc-shaped plates 11 approach and press against each other. Under the pressure, the sealing strips on the sides of the arc-shaped plates 11 deform, completely filling the tiny gaps between the sides of the two arc-shaped plates 11. At the same time, the sides of the two sealing plates 13 also press against each other, and the sealing strips on the sides of the sealing plates 13 also deform, filling the gaps between the sides of the two sealing plates 13. The deformation sealing of the double sealing strips can block the path of rainwater leakage from the side gaps, so even if a certain amount of rainwater is stored in the receiving groove 2, there will be no side leakage.

[0036] Through the above technical solution, the double sealing strip of this application further enhances the sealing performance of the cavity, preventing rainwater from leaking from the sides to the ground or surrounding items, and ensuring a more thorough anti-drip effect. The cushioning effect of the elastic sealing strip also reduces noise and wear during closure, improving the user experience and durability of the device. At the same time, the sealing strip is easy to replace, resulting in low maintenance costs.

[0037] In this embodiment, the locking assembly includes multiple magnets. Depending on their installation position, the magnets are embedded and fixedly disposed within the sides of the two arc-shaped plates 11, or embedded and fixedly disposed within the sides of the two sealing plates 13, or simultaneously disposed within both the arc-shaped plates 11 and the sealing plates 13. The number of magnets disposed within the two arc-shaped plates 11 is equal, their positions correspond to each other, and the magnetic poles of corresponding magnets are opposite, generating mutual attraction. Similarly, the number of magnets disposed within the two sealing plates 13 is equal, their positions correspond to each other, and the magnetic poles of corresponding magnets are opposite, also generating mutual attraction. This allows for a sealing fit between the two arc-shaped plates 11 and the two sealing plates 13 through magnetic attraction when the two arc-shaped plates 11 are closed.

[0038] Among them, the magnet block refers to a block structure made of permanent magnetic material. Its shape can be designed as rectangular, circular or arc according to the internal space of the arc plate 11 and the sealing plate 13. The magnetic strength needs to be sufficient to achieve stable adsorption and easy separation under manual push by the user, so as to avoid adsorption that is too tight or too loose.

[0039] Specifically, when assembling the locking assembly, grooves adapted to the magnets are first made inside the sides of the two arc-shaped plates 11. The magnets are then embedded in the grooves and fixed with glue, ensuring that the magnetic poles of the corresponding magnets on the two arc-shaped plates 11 are opposite. Grooves are then made inside the sides of the two sealing plates 13, and magnets are embedded and fixed in the same way, ensuring that the corresponding magnetic poles are opposite. When the two arc-shaped plates 1 rotate towards each other, an attraction is generated between the corresponding magnets, guiding the two arc-shaped plates 11 and the two sealing plates 13 to automatically align and fit together. When rotated to the fully closed position, the magnetic attraction force reaches its maximum, tightly fixing the two arc-shaped plates 11 and the two sealing plates 13, achieving a sealed fit. When it is necessary to open, the user applies a pushing force greater than the magnetic force, which separates the two arc-shaped plates 1, and the attraction force of the magnets disappears.

[0040] Through the above technical solution, this application achieves easier and more convenient closure of the arc-shaped groove plate 1 via magnetic adsorption locking, automatically fitting without precise alignment and improving operational convenience. The magnetic blocks experience no mechanical wear, resulting in a significantly longer service life than snap-fit ​​structures, thus reducing maintenance costs. Furthermore, the tightness of the magnetic adsorption enhances the sealing effect; when used in conjunction with a sealing strip, it further reduces the risk of rainwater leakage, ensuring stable operation of the anti-drip device.

[0041] In this embodiment, the locking components may also be a buckle and a slot. The buckle is made of elastic plastic or metal and is integrally molded or fixed to the side of one of the sealing plates 13 by screws; the slot is a groove structure opened on the side of the other sealing plate 13, the shape and size of which are completely adapted to the buckle, and the position corresponds one-to-one with the buckle; when the two sealing plates 13 are closed towards each other, the buckle can undergo elastic deformation under external pressure and embed into the slot. After being fully embedded, it returns to its original deformation and engages with the slot, thereby tightly abutting the two sealing plates 13 and achieving fixation.

[0042] Both the buckle and the slot can adopt existing structures; the buckle can be hemispherical or wedge-shaped, and the slot is a structure larger than a semicircle with an opening. The hemispherical or wedge-shaped buckle can be made of rubber, which can be squeezed into the slot and return to its initial state in the slot to achieve engagement.

[0043] Specifically, when the two arc-shaped groove plates 1 rotate and close towards each other, the latch on the side of one sealing plate 13 contacts the groove on the side of the other sealing plate 13. Under the contact pressure, the latch deforms, allowing it to slide smoothly into the groove. Once the latch is fully inside the groove, it returns to its original shape and engages with the inner wall of the groove. When it needs to be opened, the user applies a pushing force, causing the two sealing plates 13 to slightly separate. The latch deforms again until it disengages from the groove, thus releasing the mechanical lock. Subsequently, it separates under the pushing force.

[0044] Furthermore, the structure of the buckle and slot can be combined with the design of a magnetic block. When used simultaneously, the double locking structure ensures that the two arc-shaped slot plates 1 will not accidentally separate even when subjected to external forces such as shaking or collisions while in the closed state, effectively preventing rainwater leakage from the containment cavity due to device separation. At the same time, the guide alignment function reduces the difficulty of the closing operation. Users can easily complete the closing and locking without deliberately aligning, further improving the convenience of use.

[0045] Furthermore, the buckle can be a T-shaped block rotatably mounted on the top of the sealing plate 13, and the slot can be a protruding structure with a T-shaped groove on the top of the sealing plate 13. When the two sealing plates 13 are close together, the T-shaped block can be manually rotated into the T-shaped groove to achieve engagement.

[0046] In this embodiment, as shown in the appendix Figure 3 As shown, a water storage cavity 14 is provided inside the sealing plate 13. A water inlet 15 is provided on the side of the sealing plate 13 near the receiving groove 2. The water inlet 15 is connected to the water storage cavity 14. A drain outlet 16 is provided on the side of the sealing plate 13 away from the receiving groove 2. The drain outlet 16 is connected to the water storage cavity 14. A plug is provided inside the drain outlet 16.

[0047] The water storage cavity 14 is a hollow cavity located inside the sealing plate 13. Its volume is designed according to the dimensions of the sealing plate 13 and can store a certain amount of rainwater. The inlet 15 communicates with the interior of the water storage cavity 14, and its opening faces the receiving tank 2. It is used to receive the rainwater collected in the receiving tank 2 and guide the rainwater into the water storage cavity 14. The drain outlet 16 communicates with the interior of the water storage cavity 14, and its diameter is large enough to facilitate the rapid discharge of rainwater. The plug is made of rubber or soft plastic and is threaded or interference-fitted with the drain outlet 16 to seal the drain outlet 16 and prevent rainwater from overflowing from the water storage cavity 14. The plug can be removed when drainage is needed.

[0048] Specifically, when the umbrella is folded up after use, the two arc-shaped grooves 1 close to form a receiving cavity, and the rainwater remaining on the umbrella surface 5 drips into the receiving groove 2. Users typically carry the umbrella, with the sealing plate 13 at the bottom. As rainwater gradually gathers in the receiving groove 2 and flows downwards, it flows through the inlet 15 into the water storage cavity 14 inside the sealing plate 13, thus storing the rainwater. At this time, the drain outlet 16 is blocked by a plug, preventing rainwater from overflowing from the water storage cavity 14. The receiving groove 2 and the water storage cavity 14 together form a larger water storage space, capable of holding more rainwater. When the user needs to dispose of the rainwater, simply remove the plug at the top of the sealing plate 13. Under gravity, the rainwater in the water storage cavity 14 is quickly discharged through the drain outlet 16 into the sewer or a designated container. After drainage, the plug is reinstalled back into the drain outlet 16, and the device can be used again.

[0049] Furthermore, the arc-shaped plate 11 has an extension cavity inside, which is connected to the water storage cavity 14 to increase the water storage capacity.

[0050] In this embodiment, a one-way valve is provided inside the water inlet 15.

[0051] The check valve is implemented using existing technology and can be a miniature gravity check valve, a float check valve, or a diaphragm check valve. It opens when rainwater accumulates, allowing the rainwater to enter the storage tank for storage.

[0052] In this embodiment, the arc-shaped groove plate 1 is a plastic arc-shaped groove plate 1.

[0053] In this embodiment, a sealing gasket is provided at the end of the receiving groove 2 away from the sealing plate 13. The gasket may also be arc-shaped and is fixed to the inner wall by adhesive or slot. The sealing gasket has a certain compression deformation capacity. When the two arc-shaped groove plates 1 rotate towards each other to a fully closed state, the sealing gasket will tightly abut against the surface of the umbrella support 6 and fill the gap between the arc-shaped plate 11 and the umbrella support 6.

[0054] Specifically, when the two arc-shaped groove plates 1 close, the end of the arc-shaped plate 11 furthest from the sealing plate 13 (i.e., the bottom) gradually approaches the umbrella support 6. As the closure deepens, the sealing gasket first contacts the surface of the umbrella support 6. When it continues to rotate to a fully closed state, the sealing gasket is subjected to bidirectional compression from the arc-shaped plate 11 and the umbrella support 6, resulting in elastic deformation that completely fills the tiny gap between them, forming a bottom sealing barrier. At this time, the rainwater in the receiving cavity is confined within the closed space formed by the receiving groove 2, the water storage cavity 14, and the sealing gasket, and cannot leak to the outside from the gap between the bottom of the arc-shaped plate 11 and the umbrella support 6. Even if there is slight unevenness on the surface of the umbrella support 6, the elastic deformation of the sealing gasket can adapt and fill it. When the two arc-shaped groove plates 1 separate, the sealing gasket is no longer compressed and returns to its original shape, without affecting the normal rotation of the arc-shaped groove plates 1.

[0055] As attached Figure 1 and attached Figure 4 As shown, this application also proposes a folding umbrella, including the aforementioned anti-drip device for a folding umbrella. The umbrella body includes a handle 3, ribs 4, canopy 5, and support 6. The support 6 is connected to the ribs 4 via a support rod and is slidably mounted on the handle 3. By sliding the support 6, the ribs 4 can be driven to cover the umbrella, and the arc-shaped groove plate 1 can be rotated to achieve anti-drip.

[0056] Among them, the umbrella support 6 is a hollow ring structure, and a groove can be opened at the bottom to place the hinge or bushing, so as to facilitate the 180° rotation of the arc-shaped groove plate 1.

The present invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
