[0046] As a rain-proof tool, the umbrella has a long history and originated in China. With the passage of time, the materials and structures of umbrellas have been constantly improved. By the 18th century, umbrellas gradually evolved into a rain-sheltering tool, and the British began to mass-produce umbrellas and export them all over the world, improving the problem of people's travel on rainy days.

[0047] However, the umbrella ribs will inevitably be damaged after being used for a period of time, and sometimes they may even injure the user. The damage of the umbrella surface will also lead to the scrapping of the whole umbrella. Moreover, due to the influence of materials, the metal skeleton is relatively heavy in quality, and the long-term holding during use will to a certain extent affect the user experience.

[0048] The present invention provides an umbrella, aiming to provide an umbrella with light weight and high service life.

[0049] Please refer to Figure 1 and Figure 3 , in an embodiment of the present invention, the umbrella 100 includes an umbrella rod 1, a plurality of umbrella ribs 2 and an umbrella surface; the umbrella rod 1 includes an outer cylinder 11, the outer cylinder 11 has an air flow channel 12 extending from the bottom to the top, the plurality of umbrella ribs 2 are flexibly arranged, and each umbrella rib 2 has an inflation cavity 21 extending along its length direction. One end of the umbrella rib 2 is rotatably arranged at the top of the umbrella rod 1, and the air flow channel 12 is communicated with the inflation cavity 21; and, the umbrella surface is laid on the plurality of umbrella ribs 2; wherein, the inflation cavity 21 has at least a first state and a second state. In the first state, the inflation cavity 21 is used to fill with sufficient gas so that the umbrella rib 2 extends to support the umbrella surface. In the second state, the inflation cavity 21 is used to release gas so that the umbrella rib 2 bends to fold up the umbrella surface.

[0050] The technical solution of the present invention realizes the extension and folding of the umbrella rib 2 by adopting the inflation cavity 21 structure, thereby controlling the opening and closing of the umbrella surface. When it is necessary to open the umbrella surface, gas is injected into the air flow channel 12, so that the gas enters the inflation cavity 21 of the umbrella rib 2. After the inflation cavity 21 is filled with sufficient gas in the first state, the umbrella rib 2 extends due to the action of air pressure, and then supports the umbrella surface to provide rain protection for the user; when it is necessary to fold up the umbrella surface, the gas is released by controlling the air flow channel 12, the inflation cavity 21 enters the second state, and the gas therein is released. The umbrella rib 2 naturally bends without the support of air pressure, and then drives the folding of the umbrella surface, which is convenient for carrying and storing. By the flexible arrangement of the umbrella rib 2, the umbrella rib 2 can be folded smaller, reducing the occupied volume. At the same time, compared with the traditional metal umbrella rib 2, it is not easy to break, improving the safety of use and the service life of the umbrella 100.

[0051] In the present invention, the inflatable cavity 21 refers to a specific path for guiding the flow of air, which can be a straight line or a curve.

[0052] In some embodiments, the specific manner in which the umbrella ribs 2 are arranged to be flexible can be by using a hose or plastic. These materials can undergo certain deformations when subjected to pressure or tension, but can return to their original state, enabling the umbrella ribs 2 to flexibly bend during folding or unfolding without being easily broken.

[0053] Please refer to Figure 2 , in order to achieve the purpose of inflation, in one embodiment, an inflation assembly 3 is provided inside the outer cylinder 11. The inflation assembly 3 includes a cylinder 31, a slide rod 32, a push plate 33, a first valve, and an elastic member 34. The cylinder 31 is close to the bottom of the outer cylinder 11 and is provided inside the outer cylinder 11. An air inlet hole 311 communicating with the outside is provided at the bottom of the cylinder to facilitate air intake. The slide rod 32 extends along its axial direction, with one end located at the bottom of the outer cylinder 11 and the other end passing through the inside of the cylinder 31. The push plate 33 is provided at the top of the slide rod 32, and the outer peripheral wall of the push plate 33 is in contact with the inner wall of the cylinder 31. The elastic member 34 is provided between the push plate 33 and the inner top wall of the cylinder 31 to provide elastic force. And, the first valve is respectively provided at the top of the cylinder 31 to close or open the air flow channel 12 at the top of the cylinder 31. With such a setting, when it is necessary to inflate the umbrella ribs 2 to unfold the umbrella surface, the user can draw the slide rod 32 to intake air. The push plate 33 squeezes the elastic member 34 and compresses its deformation. At the same time, the push plate 33 extrudes the gas inside the cylinder 31 through the first valve and injects it into the inflatable cavity 21 of the umbrella ribs 2 to complete the inflation process.

[0054] It should be explained that the cylinder 31 can be arranged by partitioning a cavity inside the outer cylinder 11 to form the cylinder 31, or it can be directly fixedly installed inside the outer cylinder 11.

[0055] Please refer to Figure 2, To achieve the purpose of deflation, in one embodiment, the umbrella 100 further includes a deflation assembly 4. The deflation assembly 4 is located at the top of the inflation assembly 3 and is disposed inside the outer cylinder 11. The deflation assembly 4 includes a gas storage cylinder 41, a push block 42, a second valve, and an extrusion member 43. The gas storage cylinder 41 is disposed inside the cylinder 31. An opening is provided on the outer sidewall of the gas storage cylinder 41. The second valve is disposed at the top of the gas storage cylinder 41 for closing or opening the air flow channel 12 at the top of the gas storage cylinder 41. The push block 42 is movably disposed inside the gas storage cylinder 41, and one end extends to the outside of the outer cylinder 11. Further, the extrusion member 43 is disposed between the push block 42 and the inner wall of the gas storage cylinder 41 for providing tension to the push block 42 to abut against the opening. With such a setting, when it is necessary to release the gas in the gas storage cylinder 41 for other operations or to adjust the state of the umbrella 100, the user can pull the push block 42 outwards. Under the tension of the extrusion member 43, the push block 42 slides along the inner wall of the gas storage cylinder 41 and gradually moves away from the opening. At this time, the gas in the gas storage cylinder 41 flows out through the opening under the action of pressure, completing the deflation. Thus, the convenient inflation and deflation of the umbrella 100 are realized, and the practicability and operation flexibility of the umbrella 100 are improved.

[0056] It should be noted that the first valve and the second valve will open for inflation due to the impact of the gas during inflation and are in a closed state without air flow impact. During deflation, due to the opening of the opening, the gas reflux will impact the second valve to open and release the gas.

[0057] To improve the practicability of the umbrella 100, in one embodiment, the umbrella 100 further includes an extension cylinder 5. The extension cylinder 5 extends along its axis. One end of the extension cylinder 5 extends into the outer cylinder 11 and is slidably connected to the inner wall of the outer cylinder 11. A telescopic assembly 6 is provided between the extension cylinder 5 and the outer cylinder 11 for adjusting the extension or retraction length of the extension cylinder 5 relative to the outer cylinder 11. With such a setting, when it is necessary to adjust the overall length of the umbrella 100 to adapt to different environments or user needs, the user can operate the telescopic assembly 6 to make the extension cylinder 5 extend or retract relative to the outer cylinder 11.

[0058] In some embodiments, the telescopic assembly 6 may specifically include a limiting block and a limiting groove, that is, the limiting block is provided on the outer wall of the extension cylinder 5, and the limiting groove is correspondingly provided on the inner wall of the outer cylinder 11. When the extension cylinder 5 extends or retracts relative to the outer cylinder 11 to a certain specific position, the limiting block just snaps into the limiting groove, so as to limit the extension cylinder 5, prevent it from accidentally sliding during use, improve the convenience of using the umbrella 100, and ensure the safety of the user.

[0059] Specifically, in one embodiment, the telescopic assembly 6 includes a snap button and a spring member; the snap button is provided between the outer cylinder 11 and the extension cylinder 5, and one end extends to the outside of the side wall of the outer cylinder 11; one end of the spring member is connected to the side wall of the extension cylinder 5, and the other end is connected to the side wall of the snap button. Thus, when the user needs to adjust the length of the umbrella 100, the user can slide the extension cylinder 5 to extend or retract it relative to the outer cylinder 11 to the required position. At this time, under the action of the spring member, the snap button automatically snaps into the corresponding snap position on the outer cylinder 11, so as to fix the position of the extension cylinder 5, prevent it from accidentally sliding, make the length adjustment of the umbrella 100 more convenient, and improve the stability and use safety of the umbrella 100. In addition, through the snap button, it is also convenient for the user to quickly unlock the extension cylinder 5 when needed for re-adjusting the length.

[0060] In one embodiment, the umbrella 100 further includes a buffer member 7, and the buffer member 7 is provided between the outer cylinder 11 and the extension cylinder 5 for buffering when the extension cylinder 5 is adjusted. With such a setting, when the extension cylinder 5 extends or retracts relative to the outer cylinder 11, the buffer member 7 can absorb and disperse the impact force generated thereby, reduce noise, and at the same time protect the outer cylinder 11 and the extension cylinder 5 from being damaged, and extend the service life of the umbrella 100.

[0061] It can be understood that the buffer member 7 can be an elastic material, such as rubber or a spring, which is arranged on the contact surface between the outer cylinder 11 and the extension cylinder 5. When the extension cylinder 5 moves, it can play a buffering role, making the operation of the umbrella 100 more stable and improving the user experience.

[0062] Please refer to Figure 2In order to enable the umbrella surface to be adjusted for flexible use, in one embodiment, the umbrella 100 further includes a control assembly 8, which is arranged inside the outer tube 11 near the top, and includes a control tube 81, a first bevel gear disc 82, a second bevel gear disc 83, a disc 84, a shifting block 85 and a connecting rod 86; the control tube 81 is arranged inside the outer tube 11, and a first bevel gear disc 82 is arranged inside the control tube 81, and the second bevel gear disc 83 is arranged at one end of the umbrella rib 2 near the umbrella rod 1, and the second bevel gear disc 83 is meshed with the first bevel gear disc 82; the disc 84 is sleeved on the outer peripheral wall of the control tube 81, and a shifting block 85 is arranged on the outer peripheral wall of the disc 84, and one end of the shifting block 85 is located outside the outer tube 11; the two ends of the connecting rod 86 are respectively connected to the first bevel gear 82 and the opposite sides of the disc 84. With such arrangement, when it is necessary to control the opening and closing angle of the umbrella surface, the user can achieve it by operating the control component 8, that is, by turning the dial block 85, the dial block 85 drives the disc 84 to rotate, thereby the connecting rod 86 rotates, and the first bevel gear plate 82 rotates. Therefore, when the first bevel gear plate 82 rotates, it will drive the second bevel gears to rotate synchronously, and then drive the umbrella ribs 2 to rotate synchronously, so as to adjust the opening and closing angle of the umbrella surface, thereby achieving multi-posture adjustment of the umbrella surface, and improving the practicality and operational flexibility of the umbrella 100.

[0063] It should be supplemented that the control tube 81 may also be arranged inside the extension tube 5, so as to facilitate the posture adjustment of the umbrella surface after the umbrella 100 is adjusted and extended.

[0064] In order to reduce the occurrence of misoperation of the shift block 85, in one embodiment, a notch is provided on the outer peripheral wall of the outer tube 11, and the shift block 85 is located in the notch. With such a configuration, even if the user accidentally touches the shift block 85, since the shift block 85 is confined in the notch, it is not easy to cause an accidental change in the opening and closing angle of the umbrella surface, thereby enhancing the stability and safety of the umbrella 100. In addition, the notch is provided to accommodate the shift block 85, which not only avoids misoperation, but also ensures the normal operating space of the shift block 85, so that the user can smoothly adjust the opening and closing angle of the umbrella surface through the shift block 85.

[0065] It should be explained that the size of the gap is not easy to be set too large. In the present embodiment, preferably, the size of the gap is set to a quarter of the circumference, which can ensure the normal use of the shift block 85 and the support effect of the umbrella 100 after adjustment.

[0066] See also Figure 3, in one embodiment, a plurality of ventilation holes 9 are formed in the bottom of the disc 84, and the plurality of ventilation holes 9 communicate with the air flow channel 12 and the inflation cavity 21. Thus, when it is necessary to inflate the umbrella ribs 2 to deploy the umbrella surface, the inflated gas can enter the inside of the control cylinder 81 from the air flow channel 12 through the ventilation holes 9, and then enter the corresponding inflation cavities 21 of the umbrella ribs 2 respectively, realizing the synchronous extension of the umbrella ribs 2, and also improving the response speed and stability of the umbrella 100.

[0067] In one embodiment, the plurality of umbrella ribs 2 are annularly arranged on the outer peripheral wall of the outer cylinder 11. With this arrangement, when the umbrella surface is deployed, the plurality of umbrella ribs 2 can evenly support the umbrella surface, making the umbrella surface more flat when deployed, and improving the sunshade and rain protection effects of the umbrella 100. At the same time, the overall stability of the umbrella 100 can also be enhanced by the annularly arranged umbrella rib structure. Under harsh weather conditions such as strong winds, the umbrella surface can still be stably deployed, reducing the risk of the umbrella 100 being blown over or damaged by the wind.

[0068] In other embodiments, the umbrella surface can be made of special materials such as waterproof, sunscreen, wear-resistant or self-cleaning to meet the needs of different users.

[0069] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
