Description

Technical Field

[0001] This invention relates to the field of sun umbrella technology, and more particularly to an outdoor windproof sun umbrella. Background Technology

[0002] Backyard parasols are commonly used equipment in outdoor leisure settings. They typically consist of a supporting pole, radial ribs, a sunshade canopy, and a fixed base. The canopy is often made of sunshade fabrics such as polyester fiber and Oxford cloth. The overall structure is circular or square with a diameter of 2-4 meters when unfolded. They are mainly used in fixed areas such as courtyards and terraces to shield users from the sun and create a comfortable outdoor activity space. Their design focuses on sunshade effect and stability. Some products improve wind resistance by thickening the pole and adding weight to the base, but they pay less attention to the cleaning needs during daily use.

[0003] In practical applications, since patio umbrellas are placed outdoors for extended periods, their canopies easily accumulate stubborn dirt such as dust, fallen leaves, bird droppings, and tree sap. Existing umbrella designs often lack consideration for ease of cleaning: the connection between the canopy and the ribs is typically fixed, making it difficult for users to disassemble the canopy for deep washing. This makes daily manual wiping and maintenance extremely inconvenient and hinders the long-term cleanliness of the product. Therefore, a windproof outdoor umbrella is needed to address these issues.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Reference Figures 1-3 and Figure 10As shown, this embodiment of the invention provides an outdoor windproof parasol, including an umbrella assembly 1, which includes a water-filling base 11. The water-filling base 11 is the basic support component of the entire parasol. By filling it with water, its own weight can be increased, thereby providing stable bottom support for the parasol and preventing it from being blown over by the wind. The water-filling base 11 has a top cover 113, and a screw cap 111 is threadedly connected to the side of the water-filling base 11. The screw cap 111 is suitable for unscrewing to allow water to drain from the inside of the water-filling base 11. A screw cap 112 is threadedly connected to the top cover 113. The screw cap 112 is suitable for unscrewing to allow water to be filled into the water-filling base 11, thereby increasing the weight of the base and further improving the wind resistance stability of the parasol.

[0038] Furthermore, an umbrella pole 12 is fixed to the top cover 113. The umbrella pole 12 has a through hole in its center, and a movable sleeve 13 is fitted onto one end of the umbrella pole 12. The movable sleeve 13 can move up and down along the umbrella pole 12. Multiple sets of hinged umbrella ribs 14 are hinged to the movable sleeve 13 along its circumference. Furthermore, multiple sets of supporting umbrella ribs 15, corresponding to the number of hinged umbrella ribs 14, are hinged to the umbrella pole 12 near its top along its circumference. One end of each hinged umbrella rib 14 is hinged to the middle section of the supporting umbrella rib 15 near its upper end. Meanwhile, an umbrella fabric 16 is connected between multiple sets of supporting umbrella ribs 15, with one end of the umbrella pole 12 protruding from the umbrella fabric 16. The supporting umbrella ribs 15 are used to support the umbrella fabric 16, providing shape support for the umbrella surface. A windproof rope 17 is fixed to one end of the supporting umbrella ribs 15, and a ground stake 18 is connected to one end of the windproof rope 17. The windproof rope 17 is used in conjunction with the ground stake 18 to further fix the parasol to the ground, thereby improving the placement stability of the umbrella assembly 1 and enhancing the wind resistance of the parasol.

[0039] like Figures 3-7 As shown, a cleaning component 4 is fixed at one end of the umbrella pole 12 that protrudes from the umbrella fabric 16. The cleaning component 4 is used to clean the surface of the umbrella fabric 16. The cleaning component 4 includes a mounting part that is sleeved on the umbrella pole 12. The mounting part includes a fixing sleeve 419 that is movably sleeved on the umbrella pole 12. Two sets of inclined support rods 41 are integrally provided on the fixing sleeve 419. The inclination of the support rods 41 is consistent with the inclination of the umbrella fabric 16 when it is raised, so as to adapt to the shape of the umbrella fabric 16 and provide support for the subsequent cleaning components. A hinge member 42 is hinged to one end of the support rod 41, so that the cleaning component 4 can be folded synchronously with the umbrella component 1. An installation rod 43 is rotatably provided at one end of the hinge member 42 through a bearing.

[0040] Furthermore, a water spray unit is embedded in the mounting rod 43 for spraying water to clean the umbrella fabric 16. The water spray unit includes a water spray pipe 44 embedded in the upper surface of the mounting rod 43, which can deliver cleaning water. The water spray pipe 44 has inclined nozzles (not shown in the drawing) arranged along its straight direction. The inclined nozzles can not only clean the surface of the umbrella fabric 16, but also blow away some of the cleaned impurities from the surface of the umbrella fabric 16. At the same time, a hose 45 is connected to one end of the water spray pipe 44. One end of the hose 45 extends from the side of the umbrella rod 12 and extends into the water injection base 11 through the through hole in the center of the umbrella rod 12, for delivering water in the water injection base 11 to the water spray pipe 44.

[0041] Meanwhile, a partition cover 114 is integrally fixed inside the water injection base 11. The partition cover 114 is used to divide the internal space of the water injection base 11 into a water injection space and an installation space composed of the partition cover 114 and the water injection base 11. A water pump 514 is fixed in the installation space to provide power for water spraying. One end of the hose 45 is connected to the water outlet of the water pump 514, and the water inlet of the water pump 514 is connected to the water injection space through a pipe.

[0042] The mounting rod 43 has a mounting groove 49 on its bottom surface, and a cleaning brush is installed in the mounting groove 49. A slot 410 is provided on one side of the inner wall of the mounting groove 49. The cleaning brush includes a cleaning brush 411 inserted into the mounting groove 49 for directly brushing away stains on the surface of the umbrella fabric 16. One end of the cleaning brush 411 is integrally provided with a plug 412. The cleaning brush 411 is fixed by inserting the plug 412 into the slot 410. At the same time, one end of the mounting rod 43 is... The device has a receiving groove 413, with a spring 414 fixed to one end of the inner wall of the receiving groove 413. A lever 415 is fixed to one end of the spring 414. The lever 415 has a T-shaped structure, which facilitates manual operation to control the extension and retraction of the plug 416. The vertical part of the lever 415 extends into the receiving groove 413 and is connected to the other end of the spring 414. At the same time, an opening groove (not shown in the figure) is opened on the surface of the mounting rod 43 to match the width of the vertical part of the lever 415.

[0043] Meanwhile, a plug 416 is fixed on one side of the lever 415, and a socket (not shown in the figure) adapted to the plug 416 is provided at the other end of the brush handle of the cleaning brush 411. The locking and unlocking of the cleaning brush 411 is achieved by the cooperation of the plug 416 and the socket. It should be noted that in the initial state, the cleaning brush 411 is set to face downward and contact the surface of the umbrella cloth 16, and the water spray pipe 44 is set upward. Furthermore, inclined baffles 48 are fixed on both sides of the mounting rod 43 to side-block the cleaning brush 411 in the default state, so as to avoid contaminating the cleaning brush 411.

[0044] Furthermore, a sensing unit is provided on the mounting rod 43 to sense the status of the water spray pipe 44 and the cleaning brush 411, and to control the start and stop of the water pump 514. The sensing unit includes a T-shaped rod 417 fixed to one end of the mounting rod 43, and contact wheels 418 movably arranged at both ends of the T-shaped rod 417. In the initial state, a set of contact wheels 418 contacts the surface of the umbrella fabric 16, so that a part of the cleaning brush 411 contacts the surface of the umbrella fabric 16 and is adapted to rotate on the surface of the umbrella fabric 16. At the same time, when it is necessary to clean and rinse the surface of the umbrella fabric 16, the T-shaped rod 417 can be manually held and rotated 180 degrees so that the cleaning brush 411 faces upward and the water spray pipe 44 is set towards the surface of the umbrella fabric 16.

[0045] A contact 46 is located on the upper surface of the mounting rod 43, which is positioned on one side of the fixed water spray pipe 44. At the same time, a micro switch 47 is fixed on the bottom surface of the hinge 42, which is suitable for contacting the contact 46. The micro switch 47 is electrically connected to the water pump 514 to control the start of the water pump 514, thereby supplying water to the water spray pipe 44. That is, when the water spray pipe 44 is set upward, the nozzles on the water spray pipe 44 do not spray, and when the water spray pipe 44 is set downward, the nozzles on the water spray pipe 44 spray onto the surface of the umbrella fabric 16.

[0046] like Figure 4 , Figure 6 and Figure 9 As shown, a drive assembly 3 is provided at one end of the umbrella pole 12 that protrudes from the umbrella fabric 16. The drive assembly 3 is used to drive the cleaning assembly 4 to rotate around the umbrella pole 12 on the umbrella fabric 16, thereby cleaning the dirt on the surface of the umbrella fabric 16. The drive assembly 3 includes a fixed base plate 31 sleeved on the umbrella pole 12. The fixed base plate 31 is located at the upper end of the umbrella fabric 16, and a forward and reverse motor 34 is fixed on the bottom surface of the fixed base plate 31. A bevel gear 35 is fixed at the output end of the forward and reverse motor 34, and the forward and reverse motor 34 is adapted to drive the bevel gear 35 to achieve 180-degree forward and reverse rotation.

[0047] Meanwhile, a bevel gear 33 is sleeved on the umbrella shaft 12. The bevel gear 33 meshes with the bevel gear 35, which can transmit the rotational power of the bevel gear 35 and change the rotation direction. The fixing sleeve 419 is fixed to the bottom surface of the bevel gear 35 so that the cleaning component 4 moves synchronously with the bevel gear 33. At the same time, a protective cover 37 is fixed on the bottom surface of the fixing base plate 31. The protective cover 37 is sleeved on the umbrella shaft 12 and can protect the driving component from dust, rainwater and other damage to the driving component.

[0048] like Figures 7-10As shown, a power supply component 5 is provided on the fixed base plate 31. The power supply component 5 is used to provide power to the drive component 3. The power supply component 5 includes a support frame 51 fixed on the fixed base plate 31. The support frame 51 is sleeved on the umbrella pole 12. A solar panel 52 is fixed on the support frame 51. The solar panel 52 is used to convert solar energy into electrical energy. At the same time, a storage battery 513 is fixed in the installation space. The storage battery 513 is used to store the electrical energy converted by the solar panel 52 to power the drive component 3 and ensure continuous function. The storage battery 513 is connected to the solar panel 52 through wires. The wires are located in the central through hole of the umbrella pole 12. This wiring method hides the wires and avoids their influence from the outdoor environment.

[0049] Meanwhile, a push-button switch is embedded in the umbrella rod 12 to control the opening and closing of the forward and reverse motor 34. A drive shaft 53 is installed in the bearing inside one end of the umbrella rod 12. The drive shaft 53 can rotate flexibly under the support of the bearing, providing a power transmission path for the movement of the second cleaning brush 59. An installation sleeve 58 is fixed to one end of the drive shaft 53, and the second cleaning brush 59 is symmetrically fixed on both sides of the installation sleeve 58. The second cleaning brush 59 can clean the surface of the solar panel 52, removing dust, fallen leaves and other debris, ensuring the photoelectric conversion efficiency of the solar panel 52. The second cleaning brush 59 has a hollow brush shaft, and multiple sets of inclined nozzles 510 are connected to the brush shaft. When the inclined nozzles 510 spray water, they can not only assist the second cleaning brush 59 in washing away the dirt on the surface of the solar panel 52, but also use the impact force of the water flow to wash away the debris from the surface of the solar panel 52.

[0050] One end of the brush shaft is connected to the first hose 45 via the second hose to synchronously supply water into the brush shaft, realizing water transmission and utilization. A mounting cover 511 is fixed on the solar panel 52 to shield the second cleaning brush 59 when not in use. The mounting cover 511 protects the second cleaning brush 59 when not in use, preventing it from being exposed to the elements for a long time. Two sets of partitions 512 are fixed on the bottom surface of the inner wall of the mounting cover 511. The partitions 512 shield one side of the second cleaning brush 59, further restricting its position and enhancing the protective effect.

[0051] A cleaning section is provided at one end of the drive shaft 53. This cleaning section transmits the power of the forward and reverse motor 34 to the drive shaft 53, thereby driving the second cleaning brush 59 to rotate. The cleaning section includes a turbine (not shown in the figure) fixed to one end of the drive shaft 53 and extending into the umbrella rod 12. At the same time, a gear part 54 is fixed on the output shaft of the forward and reverse motor 34. The gear part 54 rotates with the output shaft of the forward and reverse motor 34. Two sets of mounting brackets 56 are fixed on the side of the umbrella rod 12. A worm gear 57 is provided through the bearing between the two sets of mounting brackets 56. The worm gear 57 meshes with the turbine and can convert the rotational power transmitted from the second gear part 55 to the turbine, thereby driving the drive shaft 53 to rotate. At the same time, a gear part 55 that meshes with the first gear part 54 is fixed at one end of the worm gear 57 that passes through the mounting bracket 56, realizing the transmission of power from the forward and reverse motor 34 to the worm gear 57.

[0052] Working principle: During use, water is injected by unscrewing the screw cap 112. The weight of the water increases the umbrella's counterweight, providing stable bottom support and effectively preventing it from being blown over by the wind. When drainage is needed, unscrewing the screw cap 111 allows the water to drain. The movable sleeve 13 can move up and down along the umbrella shaft 12, driving the hinged umbrella ribs 14 to move, thus opening and closing the umbrella canopy. The supporting umbrella ribs 15 support the umbrella fabric 16, shaping the umbrella surface. The windproof rope 17 at one end of the supporting umbrella ribs 15 is connected to the ground stake 18. After the ground stake 18 is driven into the ground, it can further secure the umbrella, improving its stability and wind resistance.

[0053] When cleaning the umbrella fabric 16 is required, first, manually hold the T-shaped rod 417 and rotate it 180 degrees so that the cleaning brush 411 faces upward and the water spray pipe 44 faces the surface of the umbrella fabric 16. At this time, the contact 46 on the mounting rod 43 contacts the micro switch 47 on the bottom surface of the hinge 42. The micro switch 47 controls the water pump 514 to start. The water pump 514 draws water from the water injection space of the water injection base 11 and delivers it to the water spray pipe 44 through the hose 45. The inclined nozzle on the water spray pipe 44 sprays water onto the surface of the umbrella fabric 16. At the same time, under the action of the drive component 3, the cleaning component 4 rotates around the umbrella rod 12 to spray water evenly onto the surface of the umbrella fabric 16. In actual use, cleaning agent can be manually sprayed onto the surface of the umbrella fabric 16.

[0054] After spraying for a certain period of time, manually rotate the T-shaped rod 417 180 degrees again, so that the cleaning brush 411 faces the surface of the umbrella fabric 16 and the water spray pipe 44 faces upward. At the same time, under the action of the drive component 3, the cleaning brush 411 brushes the surface of the umbrella fabric 16. The water sprayed from the tilted nozzle not only cleans the umbrella fabric 16, but also blows away the cleaned impurities from the surface of the umbrella fabric 16. After cleaning is completed, rotate the T-shaped rod 417 again, so that the cleaning brush 411 returns to its initial state of facing downward and contacting the umbrella fabric 16, the water spray pipe 44 faces upward, the micro switch 47 is disconnected, and the water pump 514 stops working.

[0055] The drive component 3 provides power for the rotation of the cleaning component 4. After the forward and reverse motor 34 on the bottom surface of the fixed base plate 31 is started, it drives the second bevel gear 35 to rotate in both directions. The second bevel gear 35 meshes with the first bevel gear 33 on the umbrella rod 12, transmitting power to the first bevel gear 33. Since the fixed sleeve 419 is fixed to the bottom surface of the first bevel gear 33, the cleaning component 4 rotates synchronously with the first bevel gear 33, thereby making a circular motion on the surface of the umbrella fabric 16, achieving a thorough cleaning of the umbrella fabric 16. The protective cover 37 on the bottom surface of the fixed base plate 31 protects the drive components from damage caused by dust, rainwater, etc.

[0056] Power supply component 5 provides power support for the entire system. Solar panel 52 converts solar energy into electrical energy, which is transmitted through wires (located in the central through hole of umbrella pole 12) to the battery 513 in the installation space for storage. Battery 513 supplies power to components such as the forward and reverse motor 34 of drive component 3. When cleaning the surface of umbrella cloth 16, the rotation of forward and reverse motor 34 synchronously drives the gear part 1 54 on the output shaft to rotate, which in turn drives the gear part 2 55 to rotate. Gear part 2 55 causes worm gear 57 to rotate. Worm gear 57 meshes with worm wheel at one end of drive shaft 53, driving drive shaft 53 to rotate, which in turn causes cleaning brushes 2 59 on both sides of mounting sleeve 58 to rotate, cleaning the surface of solar panel 52.

[0057] Meanwhile, hose 2 introduces water from hose 1 45 into the hollow brush shaft of cleaning brush 2 59. The inclined nozzle 2 510 on the brush shaft sprays water, assisting cleaning brush 2 59 in rinsing the surface of solar panel 52 and using the impact force of the water flow to wash away the debris. When not in use, cleaning brush 2 59 is protected by cover 511 and partition 512 to prevent it from being corroded by the outdoor environment.
