Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The purpose of this invention is to provide a fan for integration into a Roman umbrella and a Roman umbrella that provides an adjustable annular airflow area under the umbrella fabric.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-9 This embodiment provides a fan for integration into a Roman umbrella, including a central column 1 located below the umbrella fabric, and a fan 2, which includes a mounting base, an air supply assembly, and an oscillation assembly.

[0037] The mounting base includes a housing 3 and a rotating assembly. The housing 3 is used to fix the lower end of the central column 1 of the Roman umbrella. The rotating assembly is rotatably connected to the housing 3 and mutually restrained along the axial direction. The air supply assembly includes a cover 5, an air supply motor, and fan blades. The cover 5 is hinged to the rotating assembly and can adjust and maintain the relative angle. The air supply motor is fixedly connected to the cover 5. The fan blades are rotatably connected to the cover 5 and driven by the air supply motor. The oscillating assembly includes an oscillating motor 6, a first limiting block 7, and a second limiting block 8. The oscillating motor 6 is fixedly connected to the housing 3 and is drively connected to the rotating assembly to drive the rotating assembly to rotate relative to the housing 3. The first limiting block 7 is fixedly connected to the rotating assembly, and the second limiting block 8 is fixedly connected to the housing 3. The first limiting block 7 is used to abut against the second limiting block 8 when the rotating assembly rotates, so as to reverse the oscillating motor 6.

[0038] The working principle of the fan integrated into the Roman umbrella in this embodiment is as follows:

[0039] When the oscillating motor 6 is working, it drives the rotating component to rotate around its rotation axis. When it rotates to a certain angle, the limiting block 7 on the rotating component contacts the limiting block 8 on the outer casing 3, hindering the rotation of the rotating component. At this time, the output axis of the oscillating motor 6 rotates in the opposite direction, driving the rotating component to rotate in the opposite direction until the limiting block 7 contacts the limiting block 8 again. When the rotating component rotates, it drives the air supply component to rotate together, realizing air sweeping and thus forming a ring-shaped air supply area under the umbrella fabric. The sizes of the limiting blocks 7 and 8 are generally small, and their central angles corresponding to the rotation axis of the rotating component are negligible, that is, the central angle corresponding to the air supply area is approximately 360 degrees, so as to achieve a large-range air sweeping. By adopting the air supply method of reversing upon encountering resistance, the wires supplying power to the air supply motor are prevented from becoming tangled due to the continuous rotation of the air supply component.

[0040] The oscillating motor 6 includes a motor body and a control circuit for controlling the motor body. When the motor body is stalled, the current increases. Upon detecting the increase in current, the control circuit can control the motor body to reverse. The oscillating motor 6 can adopt a structure commonly used in the art, which will not be described in detail here.

[0041] The hinged position between the cover 5 and the rotating component has the ability to adjust the angle and maintain the angle after adjustment, so that the cover 5 and the rotating component maintain different angles, that is, adjust the angle between the rotation axis of the fan blade and the rotation axis of the rotating component, thereby adjusting the radius of the annular air supply area.

[0042] By combining the annular air sweeping method with the adjustment of the air sweeping radius, the air supply range can be expanded to better meet the user's needs.

[0043] In some examples, the upper end of the rotating component is gear 9, and gear 10 is fixed on the output shaft of the oscillating motor 6, with gear 9 meshing with gear 10.

[0044] The gear-driven transmission structure is relatively simple, which helps to reduce the overall size and cost. However, the actual implementation is not limited to this, and those skilled in the art can also use other transmission methods to connect the oscillating motor 6 to the rotating component.

[0045] In some examples, the lower end of the rotating assembly is a cable tray 11 fixedly connected to gear 9. A cable hole is provided on the housing 5. A hinge seat 4 is fixedly connected to the housing 5, and the hinge seat 4 is hinged to the cable tray 11.

[0046] The wires located in some sections inside the outer casing 3 pass through the center hole of gear 9, the inner hole of conduit 11 and the wire hole of casing 5, and are then connected to the blower motor to supply power to the blower motor.

[0047] The outer casing 3 includes an upper casing 14 and a lower casing 15, which are fixedly connected by screws to form a cavity inside the outer casing 3. The oscillating motor 6, gear one 9, and gear two 10 are all located within this cavity. An upper limit plate 16 and a lower limit plate 17 are fixedly connected to the outer wall of the cable conduit 11. The upper limit plate 16 is located on the upper side of the lower casing 15 and slides in contact with the upper surface of the lower casing 15. The lower limit plate 17 is located on the lower side of the lower casing 15 and slides in contact with the lower surface of the lower casing 15. By setting the upper limit plate 16 and the lower limit plate 17, the axial mutual limiting of the rotating component and the outer casing 3 is achieved.

[0048] Gear 9 is located on the upper side of the upper limit plate 16, and limit block 7 is located on the side of the upper limit plate 16. For ease of assembly, the cable tray 11 is fixedly connected to the lower limit plate 17 with screws, and gear 9 and upper limit plate 16 are fixed to the cable tray 11 with screws.

[0049] To improve the smoothness of the rotation process of the rotating assembly, the upper surface of the lower limit plate 17 has an annular protrusion 18, and the lower surface of the lower shell 15 has an annular groove into which the annular protrusion 18 extends. The annular protrusion 18 is slidably installed in the annular groove to radially limit the air supply assembly.

[0050] In some examples, at least one side of the conduit 11 is hinged to the hinge seat 4 via a straight damper 12.

[0051] The linear damper 12 can use a structure conventional in the art, and this embodiment is not particularly limited. The linear damper 12 is a hinged structure with angle holding capability. By setting the linear damper 12, the hinge between the cover 5 and the rotating component is realized, and the relative angle between the cover 5 and the rotating component can be adjusted and maintained.

[0052] In some examples, one side of the conduit 11 is hinged to the hinge seat 4 via a straight damper 12, and the other side of the conduit 11 is hinged to the hinge seat 4 via a shaft hole.

[0053] That is, only one straight damper 12 needs to be set, thereby reducing the resistance when the housing 5 rotates relative to the rotating component. Depending on the actual needs, those skilled in the art may also choose to set one straight damper 12 on each side of the cable tray 11 to provide greater damping when the housing 5 rotates relative to the rotating component.

[0054] In some examples, the linear damper 12 has a first rotating part 19 and a second rotating part 20, which are capable of rotating relative to each other. The first rotating part 19 is inserted into the hinge seat 4 and is circumferentially limited by the hinge seat 4, while the second rotating part 20 is inserted into the cable tray 11 and is circumferentially limited by the cable tray 11.

[0055] The sides of rotating part 19 and rotating part 20 include a partially cylindrical surface 21 and a longitudinal tangent plane 22, so that the cross-sectional shape of rotating part 19 and rotating part 20 is non-circular and approximately "I" shaped. After being inserted into the corresponding mounting holes, they cannot rotate freely, thereby restricting the relative rotation between rotating part 19 and hinge seat 4 and the relative rotation between rotating part 20 and cable conduit 11.

[0056] In some examples, a partition 23 is fixed inside the conduit 11. The partition 23 is used to axially limit one end of the straight damper 12, and the hinge seat 4 is used to axially limit the other end of the straight damper 12. One side of the partition 23 is used to accommodate the wire, and the other side of the partition 23 is the straight damper 12, thereby preventing the wire from being squeezed and damaged due to axial movement of the straight damper 12.

[0057] In some examples, a cylindrical shaft 13 is fixed to the side of the conduit 11, and the hinge seat 4 has a cylindrical hole facing the cylindrical shaft 13, which mates with the cylindrical hole. The cylindrical shaft 13 is coaxial with the straight damper 12.

[0058] Those skilled in the art can flexibly choose the power source for the blower motor and the oscillating motor 6.

[0059] In some examples, at least one of a battery and a power adapter is fixed on the housing 3 to supply power to the blower motor and the oscillating motor 6.

[0060] This embodiment also provides a Roman umbrella, including a central column located below the umbrella fabric, and the aforementioned fan for integration onto the Roman umbrella, wherein the outer shell is fixedly connected to the lower end of the central column.

[0061] Since the Roman umbrella includes the aforementioned fan for integration into the Roman umbrella, it also possesses the corresponding advantages of a fan, which will not be elaborated here.

[0062] In some examples, the Roman umbrella also includes photovoltaic modules. These modules can be attached to the umbrella fabric or elsewhere to power the blower motor and the oscillating motor 6.

[0063] Understandably, the battery and photovoltaic modules can be installed simultaneously, allowing the battery to be used as a backup power source when sunlight intensity is low. The wires connecting the photovoltaic modules to the casing 3 can pass through the inner hole of the central column 1, thus improving the overall aesthetics.

[0064] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
