Description

Technical Field

[0001] This application relates to a small, attachable fan device for use with sun umbrellas and umbrellas, as well as related systems and components. The device, system, and components can be used to fan an individual under a sun umbrella on which the device or system is mounted. Background Art

[0002] People sit or stand under sun umbrellas and umbrellas to avoid bad weather such as sunlight and rain. In many cases, in hot weather, people may use sun umbrellas or umbrellas to block the sun, but when the wind is very small or there is no wind or a gentle breeze, people will feel very stuffy or uncomfortably hot. Additionally, when someone smokes under a sun umbrella or umbrella, others around will also be affected by the smoke. Usually, restaurants or cafes provide large outdoor fans and place them near the tables. Such fans tend to be very noisy, with the wind force being too strong or too weak, and they need to be shared by multiple people around. After closing at night, the staff must secure the fans to prevent them from being stolen.

[0003] Although it is possible to attach existing fan devices to sun umbrellas or umbrellas, existing fan devices or systems generally cannot be used reliably without interfering with the operation of the sun umbrella or umbrella. Unreliable attachment devices may cause the fan device to fall off the sun umbrella or umbrella. Additionally, after the existing fan device is turned off and the fan blades stop rotating, the fan blades often extend out and contact the surface of the sun umbrella or umbrella or other structures after it is folded up, posing a risk of damaging the fan structure and the sun umbrella or umbrella.

[0004] As the temperature gets hotter, it becomes a challenge to enjoy the outdoors while staying cool. This application provides a much-needed solution by adding a fanning function that can be operated according to user needs, greatly enhancing the cooling effect of sun umbrellas for shading. There is a need to improve the air flow under and around sun umbrellas, umbrellas, and other structures in the field of fan devices, fan device connection methods, and fan device operating systems, and this application addresses this unmet need. Summary of the Invention

[0005] Generally speaking, the present application provides attachable fan devices and systems that can be installed and used with any one of a variety of structures, in particular, sun umbrellas and rain umbrellas. A sun umbrella or a rain umbrella equipped with an attachable fan device can be used by consumers located below or near it. The attachable fan device can fan or cool the consumer and can be controlled by a control unit. The control unit can be operated by the consumer or others, or controlled by a control source, such as a centralized control system. The control panel can prevent the user from having to stand up to adjust the fan speed and keep the user's hands away from all moving parts. Sun umbrella fans or rain umbrella fans will bring many benefits for indoor or outdoor seating or dining, or for indoor or outdoor activities, such as weddings, funerals, concerts, and sports events, restaurants, cafes, resorts, hotels, parks and other occasions.

[0006] In some embodiments, the attachable fan device of the present application includes a fan component and a sun umbrella attachment configured to be attachable to a structure such as a sun umbrella pole or a rain umbrella pole. The fan component includes two fan blades that can be operated by a motor. The rotating shaft of the fan component connects the two fan blades to the motor, and the rotating shaft includes a notched disk fixed thereto. A biasing pin can be inserted into the notch of the notched disk, and the biasing pin can be retracted by an actuator, which can be an electromagnetic actuator. During the operation of the fan and the rotation of the fan blades, in response to the opening of the switch of the attachable fan device, the rotating shaft and the notched disk also start to rotate, and the actuator actively retracts the biasing pin to overcome the biasing effect of the biasing pin. At this time, the biasing pin enters the retracted position, thereby allowing the notched disk to rotate freely. After the work is completed, in response to the closing of the switch of the attachable fan device, the actuator releases the biasing pin, and the biasing pin enters the extended position under the influence of its biasing effect. The extended biasing pin is inserted into the notch of the notched disk to stop the rotation of the disk, thereby stopping the rotation of the rotating shaft and the fan blades. The position where the notch of the notched disk is set can prevent the fan blades from rotating beyond the state parallel to the sun umbrella or rain umbrella pole. In this way, the attachable fan device can remain attached to the sun umbrella or rain umbrella before, during, and after use, and the fan blades of the attachable fan device will not interfere with the folding and retraction of the sun umbrella or rain umbrella and will not be damaged during this process.

[0007] In some embodiments, the fan system of the present application consists of an attachable fan device and a control unit for controlling the operation of the attachable fan device. The system or any of its components can be permanently, temporarily, or detachably mounted on structures such as sun umbrellas or umbrellas. The control unit includes a control circuit, which can be in the form of a dedicated electronic hardware circuit. For example, an electronic circuit that can conduct or disconnect a circuit in response to operating the control unit, such as a user-operated switch. However, in at least some embodiments, the control circuit can be configured to receive an input, determine an output, and transmit a control signal to a receiver of the attachable fan device based on the output for wired or wireless control of the attachable fan device. In some embodiments, the control unit includes a charging port for charging electronic devices such as smartphones and laptops, or powering additional devices such as LED light strings and electronic bug zappers. The control unit can be mounted on the pole of a sun umbrella or umbrella for convenient use by the user.

[0008] In some embodiments, the present application provides an attachable fan device, which includes: a fan component housing, wherein the fan component housing partially encloses an electric motor, and the electric motor includes a rotating shaft that starts to rotate when the electric motor is powered on; an electric actuator, wherein the electric actuator is electrically connected to the electric motor and operably connected to a biasing pin; a notched disk, wherein the notched disk includes at least one notch provided thereon for receiving the biasing pin, and a tubular rotating shaft operably connected to the rotating shaft of the electric motor; a fan component, wherein the fan component includes two fan blades and a central hub located between the two, and the central hub is operably attached to the tubular rotating shaft such that the two fan blades are substantially parallel to the at least one notch; wherein, the electric motor is driven by electricity, and after the electric actuator operates, the biasing pin can be withdrawn from the extended position to the retracted position. When the biasing pin is in the extended position, the biasing pin is inserted into the notch. When the biasing pin is in the retracted position, the biasing pin is outside the notch, thereby allowing the notched disk to rotate and drive the fan blades to rotate; wherein, when the electric motor is not powered on, the electric actuator releases the biasing pin from the retracted position, thereby allowing the biasing pin to enter the notch and prevent the disk and the fan blades from rotating. After the fan blades stop rotating, the fan blades are located in a position substantially parallel to the notch.

[0009] In some embodiments, for an attachable fan device as described above, the notched disk includes a pair of opposite notches provided thereon.

The attachment between each of the plurality of struts and one of the plurality of ribs is a pivotal attachment. The lower umbrella disk can slide along the central parasol pole. When the lower umbrella disk slides upward along the parasol pole, each of the struts and ribs pivotally attached thereto rotates outward relative to the central parasol pole, so that the canopy rises and the parasol fan is in the open state position. When the lower umbrella disk slides downward along the central parasol pole, each of the struts and ribs pivotally attached thereto rotates inward relative to the central parasol pole, so that the canopy descends and the parasol fan is in the closed state position.

[0014] In some embodiments of the parasol fan assembly, the lower umbrella disk is reversibly fixed to the central parasol pole and has a variety of preset open states.

[0015] In some embodiments of the sun umbrella fan assembly, the central umbrella rod, the umbrella ribs pivotally attached to the struts including the attachable fan device, and the struts including the attachable fan device are all tubular structures.

[0069] Reference Figure 1 , Figure 1An embodiment of a parasol fan structure 99 is shown, which includes a central umbrella pole and a plurality of umbrella ribs 7, wherein the central umbrella pole includes umbrella pole portions 3a, 3b, and each umbrella rib 7 is attached to a support pole 6, 6a. In the example, the parasol fan structure 99 also includes a base 10a having a base tube 10b, a lower umbrella plate 4, an upper umbrella plate 5, a plurality of attachable fan devices 12 disclosed in the present application, a control unit 13, and an electrical circuit 16 including an electrical connector 40. In any embodiment disclosed in the present application, the electrical connector can be any kind of electrical plug, plug, any kind of electrical socket, socket, or a plug and socket, such as contacts on a PCB board. In the illustrated embodiment, the parasol fan structure 99 is a structure for a central umbrella pole parasol, which includes umbrella surfaces 2a, 2b (e.g., exemplarily in Figure 17 ), vents 8, and cords 11. Cords 11 are part of an adjustment system, which will be described later, and which is used to open and close the parasol fan structure / assembly 99, 100 (assembly 100 is exemplarily shown in Figure 17 ), raising or lowering the umbrella surface 2a, 2b, and fixing the sun umbrella fan structure / assembly 99, 100 in the open or closed state.

[0070] In some embodiments, at least one pole 6a, 6b of the parasol fan structure / assembly 99, 100 includes an attachable fan device 12 disclosed in the present application. The pole including the attachable fan device 12 includes two opposing pole portions 6a, 6b, the first pole portion 6a is attached to the rib 7, the second pole portion 6b is attached to the lower umbrella plate 4, and the two opposing pole portions 6a, 6b are both attached to the attachable fan device 12 disposed therebetween. In this embodiment, wherein the parasol fan is a central umbrella pole type parasol fan (as shown in the figure), the pole / pole portion 6, 6a is attached to the rib 7 in a pivotable manner, and the pivotable attachment is achieved by attaching each rib 7 and the pole / pole portion 6, 6a associated therewith to the joint 41. In some embodiments (as shown in the figure), the second pole portion 6b is attached to the lower umbrella plate 4 in a pivotable manner. In addition, in the embodiment shown in the figure, each of the plurality of ribs 7 includes a first end and a second end. The second end is connected to the umbrella surface 2a, 2b (such as Figure 16 As shown), the first end is pivotally attached to the upper umbrella plate 5.

[0071] The attachable fan device 12 shown in the figure is attached to several poles 6a, 6b of the sun umbrella structure 99, for example, to four pairs of poles 6a, 6b. In some embodiments, the direction in which the attachable fan device 12 is arranged can make the blades 17 of the attachable fan device 12 blow wind toward the umbrella surface 2a, 2b (such as Figure 17an area below or near the one shown in the figure, for example, blowing the wind towards a user sitting under the umbrella surfaces 2a and 2b. In this way, when the umbrella surfaces 2a and 2b are in the open state and the attachable fan device 12 starts to work, people sitting under the umbrella surfaces 2a and 2b or those near the fan device 12 can be blown by the wind fanned by the fan, so that they can better keep cool, reduce sweating, or avoid overheating. Another example of using the attachable fan device 12 is that if a smoker is sitting on a chair under the umbrella surfaces 2a and 2b, the attachable fan device 12 blows the smoke away to avoid affecting other people near the smoker or those who do not want to inhale or be exposed to second-hand smoke.

[0072] Furthermore, the fan blades 17 of the attachable fan device 12 are configured to be parallel to the strut portions 6a and 6b when the fan blades do not rotate or stop rotating. Therefore, when the sunshade fan structure / components 99 and 100 are in the open state (as shown in the figure) or in the closed state (i.e., folded into a collapsed state for the storage or transportation of the sunshade fan structure / components, for example, when not in use), the attachable fan device 12 can be kept attached to the strut portions 6a and 6b of the sunshade.

[0073] In some embodiments, the umbrella pole portion 3a is attached to the bases 10a and 10b, and the attachment method can be a reversible attachment. In some embodiments, the sunshade fan structure 99 includes a control unit 13, and the control unit includes at least one switch 33. In Figure 1 the exemplary embodiment shown, the switch 33 is operably functionally connected to at least one attachable fan device 12. In some embodiments, the control unit 13 includes a plurality of switches 33, and each switch 33 is operably functionally connected to an attachable fan device 12 (for example, operating the attachable fan device 12 located roughly above the switch 33). In some other embodiments, one switch 33 is operably functionally connected to more than one attachable fan device 12.

[0074] In some embodiments, the control unit 13 further includes a charging port 32 for charging personal electronic devices such as the user's mobile phone, laptop, etc. In some embodiments, the control unit 13 is powered by an electrical line 16. In the example shown, the electrical line 16 supplies power to the control unit 13, and the electrical line 16 runs from below the base 10a through the base tube 10b and through the central umbrella rod 3a towards the control unit 13 through an opening 42 (as shown in FIG. 4b) formed in the outer periphery of the base 10a. In some embodiments, the base 10a is a hollow structure, and in some other embodiments, the base 10a includes a groove (not shown) for cooperating with the electrical line 16. The end of the electrical line 16 is located outside the base 10a, and the sun umbrella fan structure 99 includes an electrical connector 40. The electrical connector 40 is used to operably connect to an electrical socket / plug. In some embodiments, the electrical connector 40 is operably connected to a power converter. In some embodiments, the umbrella rod portion 3a further includes an opening 43 disposed near the end of the umbrella rod portion attached to the bases 10a, 10b. The opening 43 will be further described herein. Although a central umbrella rod type sun umbrella is shown in the figures, other types of sun umbrellas, sun umbrella configurations, and sunshade structures are equally applicable without departing from the scope of the present application.

[0075] Reference Figure 2 , Figure 2 FIG. shows a perspective view of a part of the sun umbrella fan structure 99. It should be noted that the attachable fan device 12 can also be attached to any part of the sun umbrella fan structure / assembly 99, 100, or can actually be attached to any part of a suitable structure. However, in the configuration shown in the figure, the attachable fan device 12 is attached to the strut portions 6a, 6b of the sun umbrella fan structure / assembly 99, 100. The figure shows the attachable fan device 12 in a closed state, at which time the fan blades 17 are parallel to the strut portions 6a, 6b of the sun umbrella fan structure. When the attachable fan device 12 is in the closed state (non-operating state), the sun umbrella fan structure / assembly 99, 100 can be folded (i.e., the closed state in the text) or unfolded (e.g., not closed or opened), and the lowering and rising of the umbrella surfaces 2a, 2b will not damage the fan blades 17, and the fan blades 17 will not damage the sun umbrella fan structure / assembly 99, 100 or the umbrella surfaces 2a, 2b.

[0076] Figure 2shows a configuration in which the umbrella rib 7 is pivotally attached to the support rod 6 and a configuration in which the umbrella rib 7 is pivotally attached to the support rod portion 6a and then attached to the attachable fan device 12 and the support rod portion 6b. In both configurations, the umbrella rib 7 is pivotally attached to the central umbrella rod 3 through the upper umbrella disk 5. The support rod / support rod portions 6, 6b are pivotally attached to the lower umbrella disk 4 and slidably attached to the central umbrella rod including the umbrella rod portions 3a, 3b through the lower umbrella disk 4. The sun umbrella fan structure / components 99, 100 can be assembled and provided as a module. Optionally, the sun umbrella fan structure / components 99, 100 can be added or improved after sale as an assembly of the sun umbrella or umbrella and fan system of the present application. In some embodiments, the parts of the sun umbrella fan structure / components 99, 100 are tubular or partially tubular. For example, any one or some of the following parts can be tubular or partially tubular: the base tube 10b, the umbrella rod portions 3a, 3b, the control unit 13, the support rod / support rod portions 6, 6a, 6b, and / or the umbrella rib 7. The tubular structure of the present application can be any type commonly used in the art and has a suitable size, length, and shape.

[0077] In some embodiments, the electrical line 16 transmits electric power from an AC power source to the control unit 13 or directly to the attachable fan device 12. Here, the alternating current is converted into direct current and drives the motor 20 of the fan device 12. For a central umbrella rod type sun umbrella or umbrella, the electrical line 16 can run along the inside of the umbrella rod portions 3a, 3b and upward towards the upper umbrella disk 5, and then along or inside the umbrella rib 7 towards the support rod 6a (running along or inside the support rod 6a) and electrically connected to the attachable fan device 12. For a cantilever type sun umbrella, the electrical line 16 can run along or inside the umbrella rod towards the upper joint of the cantilever type sun umbrella, then downward towards the umbrella surface and along or inside the umbrella rib, and then along or inside the support rod 6a and electrically connected to the attachable fan device 12. In some embodiments (as shown in the figure and described herein), the electrical line runs upward along the umbrella rod portion 3a or inside the central umbrella rod and is electrically connected to the control unit 13, and then the electrical line 16 leads out from the control unit 13 and runs upward along or inside the umbrella rod or the umbrella rod portion 3b, and then reaches the umbrella rib 7 and the support rod portion 6a, as described above, and finally is electrically connected to the attachable fan device 12. However, in the shown embodiments, wired power transmission and wired control of the control unit 13 for the power transmitted to the attachable fan device 12 are implemented, but other configurations and implementation manners can also be used as described elsewhere in this document.

[0078] Figure 3 shows Figure 2Partial disassembly view of the sun umbrella fan structure shown. In some embodiments, the umbrella rod, such as the central umbrella rod, includes two opposite umbrella rod portions 3a, 3b. The first umbrella rod portion 3a is attached to the first ends of the bases 10a, 10b and the second end of the control unit 13. The second umbrella rod portion 3b is attached to the first end of the control unit 13 and the second end of the upper umbrella disc 5 or the upper joint. In some embodiments, the control unit 13 includes at least one opening 47 at a position near each end. In some other embodiments, the control unit 13 includes a pair of oppositely positioned openings 47, and the pair of openings 47 are provided at positions near the ends of the control unit 13. The oppositely arranged openings mean that the fixing device defined herein can be inserted into one of the openings and then into the other opening, so that the fixing device is inserted into both openings simultaneously. In the example shown, the umbrella rod portion 3b includes an opening 46 provided near its first end. In other embodiments, the umbrella rod portion 3b includes two oppositely positioned openings 46 provided near its first end. In some embodiments, the process of attaching the control unit 13 to the umbrella rod portions 3a, 3b is accompanied by aligning the openings 46 and 47 so that the openings 46 and 47 coincide and are fixed together by a fixing device passing through them. The fixing device can be but is not limited to nails, screws, rivets, tacks, pins, bolts, blind nails (such as metal blind nails) or combinations thereof. In some embodiments, when the sun umbrella fan structure / assembly 99, 100 includes a plurality of switches 33 and a plurality of attachable fan devices 12, and each switch 33 is operably connected to an attachable fan device 12, the control unit 13 is attached to the umbrella rod portion 3b in such a way that the switch 33 is generally located below a certain attachable fan device 12 that it operates. Thus, for the sun umbrella fan assembly 100 including a plurality of attachable fan devices 12, when a user sitting below it wants to operate only one attachable fan device 12 directly above him / her, he / she can switch the switch 33 closest to him / her. In addition, according to some embodiments, the struts 6, 6b are pivotally attached to the lower umbrella disc 4 by using opposite openings 45, as further described and shown in the text. In some embodiments, the ribs 7 are pivotally attached to the upper umbrella disc 5 by using opposite openings 44, as further described and shown in the text.

[0079] Refer to Figure 4A , a partial view of the sun umbrella fan 99 shows the control unit 13 attached to the umbrella rod portion 3a, and the umbrella rod portion 3a is attached to the base tube 10b and the base 10a. The opening 42 in the base 10a allows the passage of the electrical line 16. Optionally, the electrical line 16 may not pass through the bases 10a, 10b, but directly be inserted or enter the umbrella rod portion 3a through the opening 43.

[0080] Figure 5A partial disassembled view of the control unit 13, the umbrella rod portion 3a, and the bases 10a, 10b is shown. The electrical line 16 passes through the opening 42, enters the interior of the base tube 10b (not shown) from below the base 10a, and enters the umbrella rod portion 3a after being led out from the base tube 10b. Opposite openings 47 near the bottom end of the control unit 13 are used to align and coincide with corresponding openings 46 near the second end of the umbrella rod 3a. The control unit 13 is attached to the umbrella rod portion 3a by inserting into the aligned and coinciding corresponding openings 46, 47.

[0081] Although the fixing device and the designated openings for use with the fixing device are described herein, the central umbrella rod or the umbrella rod portions 3a, 3b can also be attached to the control unit 13 by other methods. For example, a spring-driven collar can be used to mate with and snap into corresponding openings (not shown). Optionally, a sleeve with a customized socket can be snap-fitted to the body of the control unit 13. For example, the socket can have a specific size and be configured to make a tight contact with a specific corresponding structure, such as the umbrella rod portions 3a, 3b of a specific sunshade or umbrella. In this way, different sockets can be provided specifically for attaching to different structures or other components, such as the above-mentioned sleeve and the control unit 13, and these sockets can be standardized or manufactured according to certain specifications (not shown).

[0082] Figure 6 The shown umbrella rod portion 3b is attached to the upper umbrella disk 5 and slidably attached to the lower umbrella disk 4. An exemplary illustration in the figure shows an adjustment system for opening or closing the sunshade fan structure / components 99, 100 (the component 100 is Figure 17 exemplarily illustrated), raising or lowering the umbrella surfaces 2a, 2b, and fixing the sunshade fan structure / components 99, 100 in the open or closed state. The adjustment system includes a rope 11 and a spool 14. In some embodiments, each of the upper umbrella disk 5 and the lower umbrella disk 4 includes a spool 14. The spools 14 are aligned vertically and arranged facing each other for adjusting the distance of the lower umbrella disk 4 relative to the upper umbrella disk 5 together with the rope 11. In some other embodiments, each of the upper umbrella disk 5 and the lower umbrella disk 4 includes two spools 14. The two spools 14 on each umbrella disk 4, 5 are relatively arranged on the inner peripheral side of the umbrella disks 4, 5 (this peripheral side is circular and close to the umbrella rod portion 3b). In the present embodiment, the two spools 14 of the upper umbrella disk are both used in conjunction with one spool 14 of the lower umbrella disk 4 that is vertically aligned and arranged facing each other, and cooperate with the rope 11 to help adjust the distance of the lower umbrella disk 4 relative to the upper umbrella disk 5. The lower umbrella disk 4 further includes a pin 15 for inserting into an opening 36 on the umbrella rod portion 3b (as Figure 10 shown) and fixing the lower umbrella disk 4 in a desired position. A part 37A of the sunshade fan structure 99 is further shown in Figure 7 while a part 38A is further shown in Figure 10 respectively.

[0083] Although an adjustment system including a rope 11 and a pulley 14 is listed for opening, closing, raising, and lowering the umbrella surfaces 2a, 2b of the sunshade fan assembly 100, any type of adjustment system commonly used in the art that can be used to place a sunshade / umbrella structure in an open or closed state can be applied to the sunshade fan structures / components 99, 100 disclosed in this application. For example, the adjustment system may include, but is not limited to, levers, pulleys, ropes, pull rings (e.g., pull rings that cooperate with specific openings), springs, friction fits, pins (e.g., pins that cooperate with specific openings), nested telescopic joints, and combinations thereof.

[0084] Figure 7 A partial view 37A is shown. The upper umbrella disk 5 includes a bracket 48, and the bracket 48 includes a pin 49 for pivotally attaching to the opposing opening 44. The pin 49 can be any fixing device applicable thereto. The pulley 14 and the associated rope 11 are shown in the figure. An example of the upper umbrella disk 5 is shown in Figure 8 which is further shown in, where multiple electrical lines 16 extend from the upper umbrella disk 5, and each electrical line includes an electrical connector 40. Figure 9 This is an exploded view of the upper umbrella disk 5 disclosed in this application, which includes a disk cap 50, an upper cover 51, and a bottom cover 52. The bottom cover 52 includes two pulleys 14 positioned opposite each other. The upper umbrella disk 5 includes a plurality of brackets 48, and the brackets 48 include pins 49. The number of brackets corresponds to the number of umbrella ribs 7 included in the sunshade fan structures / components 99, 100. In the illustrated example, the sunshade fan structures / components 99, 100 include eight umbrella ribs 7, and four of the umbrella ribs are pivotally attached to a strut 6a to which a fan device 12 can be attached. In some embodiments, the umbrella ribs 7 pivotally attached to the strut 6 and the umbrella ribs 7 pivotally attached to the umbrella rib 6a are arranged alternately.

[0085] In some embodiments, the upper umbrella disk 5 includes a PCB board 53, and the electrical line 16 from the control unit 13 is electrically connected to the PCB board 53. In Figure 9In the illustrated embodiment, the PCB board 53 includes an electrical connector 57 for electrically connecting to the electrical line 16 from the control unit 13, and the electrical connector 56 is electrically connected to the electrical connector 57. The electrical connector 56 in turn is electrically connected to the electrical connector 40 of the electrical line led out from the upper umbrella disk 5 and the electrical line routed along or within the umbrella rib 7. The bottom cover 52 and the PCB board 53 include a central opening 55. The central opening 55 is used to cooperate with one end of the umbrella rod portion 3b within the upper umbrella disk 5 to allow the electrical line 16 from the control unit 13 to enter the upper umbrella disk 5. In some embodiments, the upper umbrella disk 5 does not include the PCB board 53, and the electrical line 16 from the control unit 13 enters the upper umbrella disk 5 through the opening 55 and is thus routed along or within the umbrella rib 7 pivotally attached to the strut 6a. In the illustrated embodiment, the electrical line 16 from the control unit 13 enters the upper umbrella disk 5 through the opening 55 and is electrically connected to the electrical connector 57 here. The electrical line 16 including the electrical connector 40 is electrically connected to the electrical connector 56 and passes through the opening 54 on the bracket 48, so as to be routed along or within the umbrella rib 7 pivotally attached to the strut 6a. Further, after the upper cover 51 and the bottom cover 52 are assembled, the opening 85 provided therebetween is for the passage of the electrical line 16, where the line 16 first passes through the opening 54. In some embodiments, the PCB board 53 further includes an electrical connector 58, which will be further discussed herein.

[0086] After the upper cover 51 and the bottom cover 52 are assembled together, they have flanges 88, 89. And, there is a groove 86 between the flanges 88, 89, and the bracket 48 extends upward from the groove 86 to the outside of the upper umbrella disk 5. It should be noted that the side surface or side wall of the groove 86 is uneven, so the bracket 48 extends to the outside of the upper umbrella disk at an oblique angle. Therefore, the umbrella rib 7 pivotally attached to the bracket 48 by the pin 49 also has an oblique angle relative to the central umbrella rods 3a, 3b, which means that the line arranged above or inside the umbrella rib 7 and directly extending outward therefrom does not pass through the midpoint or approximately midpoint of the umbrella rod portion 3b, or does not pass through the midpoint or approximately midpoint of the upper umbrella disk 5. Similarly, the lower umbrella disk 4 (such as Figure 29After the top cover 80 and the bottom cover 81 (as shown) are assembled together, they have flanges 88, 89 which are parallel to the flanges 88, 89 of the upper umbrella disc 5 in the vertical direction. There is a groove 86 between the flanges 88, 89 of the lower umbrella disc 4, and the bracket 48 extends downward from the groove 86 to the outside of the lower umbrella disc 4. Similar to the upper umbrella disc 5, the side or side wall of the groove 86 is not flat, so the bracket 48 extends to the outside of the lower umbrella disc at an oblique angle. The groove 86 of the upper umbrella disc 5 and the groove 86 of the lower umbrella disc 4 are perpendicular and parallel to each other in shape. Therefore, the struts 6, 6b pivotally attached to the bracket 48 of the lower umbrella disc 4 by pins 49 also have an oblique angle relative to the central umbrella poles 3a, 3b, which means that the wires arranged above or inside the struts 6, 6b and extending directly outward from them do not pass through the midpoint or approximately midpoint of the umbrella pole portion 3b, or do not pass through the midpoint or approximately midpoint of the lower umbrella disc 4. The oblique angles of the umbrella ribs 7 and the struts 6, 6b are similar or the same. The oblique angle attachment described and shown herein can make room for the motor 20 (and the housing 19) and allow the sun umbrella fan structure / assembly 99, 100 to have the smallest possible size when closed.

[0087] In some embodiments, the lengths of the flanges 88 and 89 are not equal. In the illustrated embodiment ( Figure 9 and Figure 29 ), the flange 89 is longer than the flange 88 in the horizontal direction. In the illustrated embodiment, on the first side of each flange 88, which is adjacent to the shallower side / wall of the groove 86, there is an umbrella rib 7 pivotally attached to the strut 6a, and the strut 6a is attached with an attachable fan device 12. On the other side of each shorter flange 88, there is an umbrella rib 7 pivotally attached to the strut 6, and the strut 6 is not attached with an attachable fan device 12. Therefore, in some embodiments, the sun umbrella fan structure / assembly 99, 100 disclosed in the present application includes multiple pairs of umbrella ribs 7. Each pair of umbrella ribs 7 includes an umbrella rib 7 pivotally attached to a strut 6 that is not attached with an attachable fan device 12, and an umbrella rib 7 pivotally attached to a strut 6a that is attached with an attachable fan device 12, and the space between the pairs of umbrella ribs is greater than the space between the two umbrella ribs of the same pair of umbrella ribs. The uneven gaps described and shown herein can also make room for the motor 20 (and the housing 19) and allow the sun umbrella fan structure / assembly 99, 100 to have the smallest possible size when closed.

[0088] Figure 10Shows a partial view 38A, where the lower umbrella disk 4 includes a wire reel 14, and the wire reels 14 are all associated with the rope 11. In some embodiments, the lower umbrella disk 4 includes an orifice 60 for the rope 11 to pass through the lower umbrella disk 4. The lower umbrella disk 4 includes a number of brackets 48, and the brackets 48 contain pins 49 for pivotally connecting to the struts 6 and strut portions 6a through the opposing openings 45. The lower umbrella disk 4 and the upper umbrella disk 5 have the same number of brackets 48. The lower umbrella disk 4 includes a pin 15 for fixing the lower umbrella disk 4 to a preset position on the umbrella pole portion 3b relative to the upper umbrella disk 5. The pin 15 is attached to the lower umbrella disk 4 by a chain 59, and the pin 15 mates with an opening 36 on the umbrella pole portion 3b. In some embodiments, there are a number of openings 36, and each opening 36 sets a preset state of the sunshade fan structure / component 99, 100, for example, an open state or a closed state. In some embodiments, the sunshade fan structure / component 99, 100 disclosed in the present application includes multiple preset open states, so there are multiple openings 36 located at different positions. Each preset open state sets the degree to which the umbrella ribs 7 are deployed relative to the central umbrella pole or the umbrella pole portion 3b. Each preset open state also sets the angle of the struts 6a, 6b relative to the central umbrella pole or the umbrella pole portion 3b, thereby setting the position of the attachable fan device 12 relative to the user using the sunshade fan structure / component 99, 100. Therefore, the user can set the sunshade fan structure / component 99, 100 to multiple open states to adjust the position of the attachable fan device 12, thereby adjusting the direction of the airflow generated by the attachable fan device 12 as needed. Figure 10 The two openings 36 shown in [Fig. 2] set two open states. Other possible states of the sunshade fan structure / component 99, 100 will be discussed further herein.

[0089] As Figure 11 and 12 shown, the assembly 61 includes umbrella ribs 7, struts 6, and connectors 41. The connectors 41 are for sleeving on the umbrella ribs 7 and enabling the umbrella ribs 7 to be pivotally attached to the struts 6 by pins 64, and the pins 64 pass through the opposing openings 63 and 62 respectively provided on the umbrella ribs 7 and the struts 6. Generally speaking, according to the present application, the pins can be replaced with any other fixing devices. In some embodiments (not shown), the assembly 61 does not include the connectors 41, and the struts 61 are pivotally attached to the umbrella ribs 7 by pins 64, and the pins 64 pass through the opposing openings 63 and 62 respectively provided on the umbrella ribs 7 and the struts 6, thereby pivotally fixing them together.

[0090] As Figure 12 and 13As shown, the assembly 65 includes an umbrella rib 7, poles 6a, 6b, an attachable fan device 12, and a joint 41. The joint 41 is used to be sleeved on the umbrella rib 7 so that the umbrella rib 7 can be pivotally attached to the pole 6a by means of a latch 64, and the latch 64 passes through the opposite openings 63 and 62 respectively provided on the umbrella rib 7 and the pole 6a. In some embodiments, the umbrella rib 7 of the assembly 65 also includes an opening 66 for passing the electrical circuit 16, which runs from the inside of the umbrella rib 7 along or inside the pole 6a, and then is operably electrically connected to the attachable fan device 12. An embodiment of the components of the attachable fan device 12 is shown in the figure. As shown in FIG. Figure 14 In the example shown, the attachable fan assembly 12 includes a housing 19 that partially encloses a motor 20, and the motor 20 includes a shaft 84 that rotates when the motor is driven by electricity. In some embodiments, the attachable fan assembly 12 further includes an electric actuator 23 that is electrically connected to the motor 20 and operably connected to the biasing pin 24 (e.g., Figure 15 In some embodiments, the attachable fan assembly 12 further comprises a notched disc 25. The notched disc comprises at least one notch 26 disposed on its outer edge (e.g., Figure 15 ), the notch is used to accommodate the biasing pin 24. In some embodiments, the notched disc 25 further includes a tubular shaft 27, which is used to be attached and operably connected to the shaft 84 of the motor 20. The attachable fan device 12 disclosed in the present application also includes a fan component, which includes two blades 17 and a blade hub 28 disposed therebetween. The blade hub 28 is used to be operably attached to the tubular shaft 27 and make the blades 17 substantially parallel to the at least one notch 26.

[0091] In some embodiments, when the motor 20 is electrically driven, the electric actuator 23 is turned on and the biasing latch 24 is withdrawn from the extended position to the retracted position, wherein when in the extended position, the biasing latch 24 is inserted into the notch 26, and when in the retracted position, the biasing latch 24 is located outside the notch 26, thereby allowing the notched disc 25 to rotate, and then the fan blades 17 to rotate. However, when the motor 20 is not electrically driven, the electric actuator 23 releases the biasing latch 24 from the retracted position, so that the biasing latch 24 enters the notch 26, thereby preventing the notched turntable 25 and the fan blades 17 from rotating. Since the connection between the fan assembly 28, 17 and the tubular shaft 27 makes the fan blades 17 roughly parallel to at least one notch 26, this means that when the rotation of the fan blades stops, the fan blades 17 are located at a position roughly parallel to the notch. In some embodiments, the notched disc 25 includes a pair of notches 26 that are positioned opposite to each other.

[0092] In some embodiments, the attachable fan device 12 further includes two opposite parasol attachments 18. In some embodiments, the parasol attachment 18 is a tubular structure and has a first end and a second end. The first ends of the parasol attachments 18 are each attached to the fan component housing 19 (also referred to herein as the housing), and the parasol attachments 18 are generally parallel to the biasing pin 24. In some embodiments, the attachable fan device 12 further includes a top mounting bracket 67 and a bottom mounting bracket 68. The top mounting bracket 67 and the bottom mounting bracket 68 are configured to accommodate an actuator 23 and a biasing pin 24 that are located therebetween and parallel to the parasol attachments 18. In some embodiments, the top mounting bracket 67 snaps onto the bottom mounting bracket 68, and the bottom mounting bracket 68 is fixed to the parasol attachment 18 by a fixing means passing through the coinciding openings 69 and 70. In some embodiments (such as Figure 14 as shown), the second end of one parasol attachment 18 is directly attached to the strut portion 6a and the second end of the other parasol attachment 18 is directly attached to the strut portion 6b. In some embodiments, components of the attachable fan device 12, such as the motor 20, the actuator 23, the biasing pin 24, the housing 19, the top mounting bracket 67, the bottom mounting bracket 68, a portion of the notched disk 25, and / or a portion or the whole of the parasol attachment 18 are shrouded by the motor housing 21.

[0093] Figure 15An exploded view of another embodiment of the fan device 12 disclosed in the present application is shown. The attachable fan device 12 includes fan components 28, 17 directly or indirectly attached to the sunshade attachment 18. The sunshade attachment 18 is used to attach the fan components 28, 17 to a structure, such as a structure of a sunshade or an umbrella. The components of the fan components 28, 17 are operably attached to the motor 20, and the motor 20 is partially covered by the housing 19. In some embodiments, the housing 19 includes a surface having an opening 71 for the rotation shaft 84 of the motor 20 to pass through, and this surface includes side walls provided along its outer edge. In some embodiments, the housing 19 includes a groove 72 for cooperating with the biasing pin 24 in a position parallel to the sunshade attachment 18. In some embodiments, the housing 19 further includes an opening provided near the groove 72 for connecting the electrical connection or routing of the electric actuator 23 to the electric motor 20. The electric motor 20 is fixed to the housing 19 through the motor housing 21, and the motor housing 21 covers the motor 20 and other components of the attachable fan device 12. In some embodiments, the sunshade attachment 18 includes a sunshade attachment plug 22, and the sunshade attachment plug 22 has a specific size and shape such that the sunshade attachment 18 can be connected to a corresponding structure with a specific size and shape, for example, the struts 6a, 6b having a specific size and shape. The actuator 23 (for example, the solenoid actuator 23) is operably electrically connected to the motor 20 and operates the pin (biasing pin) 24, and the pin 24 biases towards the notched disk 25, and the notched disk 25 has one or more notches 26 provided thereon. The notched disk 25 is fixed to the motor rotation shaft 84 and thus can be attached to the hub 28 connecting the fan blade 17 of the attachable fan device 12. During the operation of the motor 20, the rotation shaft 84 rotates to drive the notched disk 25 and the rotatable fan blade 17 to rotate. The electric actuator 23 is powered on and withdraws the biasing pin 24 from the extended position to the retracted position and holds the biasing pin 24 in the retracted position. When the operation stops, the electric actuator (for example, the electromagnetic actuator) 23 releases the biasing pin 24 to enter the extended position and insert into the notch 26 on the notched disk 25, so that the notched disk 25, the rotation shaft 27, and the rotatable fan blade 17 stop rotating and enter the pause position. Then, the notch 26 of the disk 25 is adjacent to or parallel to a portion of the struts 6a, 6b and prevents the fan blade 17 from rotating and exceeding the state parallel to a portion of the sunshade fan structure / component 99, 100 or the struts 6a, 6b of the umbrella. In this way, the attachable fan device 12 can continue to be attached to the sunshade fan structure / component 99, 100 or the umbrella regardless of before use, during use, or after use, and the fan blade 17 of the attachable fan device 12 will not interfere with the closing and folding of the sunshade fan structure / component 99, 100 or the umbrella and will not be damaged, thus greatly facilitating the employees or other personnel participating in the maintenance or use of the component to open or close the device.

[0094] In some embodiments, the biasing pin 24 can be mechanically biased by a spring. For example, the biasing can be a mechanical bias built into the actuator 23 and occurs when the actuator 23 is de-energized (i.e., not driven). The biasing pin 24 can be inserted into the notch 26 of the disk 25 and can be retracted by the actuator 23, such as an electric actuator 23, for example, an electromagnetic actuator. During the operation of the attachable fan device 12 and the rotation of the fan blade 17, in response to the user turning on the attachable fan device 12, the rotating shaft 27 and the notched disk 25 also start to rotate. The actuator 23 actively retracts the biasing pin 24 to overcome the bias of the biasing pin 24. When the biasing pin 24 enters the retracted position, the notched disk 25 can rotate freely. When the operation is completed, in response to the user turning off the attachable fan device 12, the actuator 23 releases the biasing pin 24, and under the influence of the biasing effect, the biasing pin 24 enters the extended position. The biasing pin 24 may come into partial contact with the notched disk 25 during its rotation. The extended biasing pin 24 enters the notch 26 of the disk 25 and prevents the disk 25 from further rotating, thereby stopping the rotation of the rotating shaft 27 and the fan blade 17. The fan blade 17 will be located directly above the notch 26, and when the notched disk 25 is not rotating, the notch 26 and the fan blade 17 are parallel or at least substantially parallel to the strut portions 6a, 6b.

[0095] Figure 16 and 17 Fig. shows a sunshade fan assembly 100, which generally includes the sunshade fan structure 99 disclosed in the present application and any type of umbrella surface 2a, 2b applicable thereto. For example, the umbrella surfaces 2a, 2b can be designed as a one-piece and have various features, such as apertures, or be designed as a multi-piece with gaps between the pieces. The above-mentioned gaps or apertures can be used as ventilation openings to allow air to circulate when the attachable fan device is operating. In the figure, the sunshade fan assembly 100 is in a preset open state, for example, a fully open preset state, in which the umbrella surfaces 2a, 2b are maximally expanded horizontally to the preset open state. The air circulation during the operation of the attachable fan device 12 is achieved by the air around the sunshade fan assembly 100 and the air introduced from above the sunshade fan assembly 100 through the ventilation opening 8. The ventilation opening 8 is mainly the gap between the umbrella surfaces 2a and 2b, and the ventilation opening 8 allows the air from above the sunshade fan assembly 100 to enter the air flow cycle. Although the ventilation opening 8 is described in one embodiment, those skilled in the art should understand that the ventilation of the sunshade umbrella surface can also be achieved by various other methods. For example, especially in the embodiment where the umbrella surfaces 2a, 2b of the sunshade fan assembly are one-piece, the umbrella surfaces 2a, 2b can also be provided with any number, size, and shape of apertures. Figure 18 Fig. shows Figure 17a local part 39A therein, where a joint 41 pivotally attaches a stay 6a (stay 6 for adjacent umbrella ribs 7) to the umbrella rib 7, and one end of the joint 41 is inserted into a fixed sleeve 73. The fixed sleeve 73 is arranged along the outer periphery of the umbrella surface 2a, and each joint 41 is reversibly attached to the fixed sleeve 73 to keep the umbrella surface 2a attached to the sunshade fan structure 99. Similarly, the fixed sleeve 74 is arranged along the outer periphery of the umbrella surface 2b, and the end of the umbrella rib 7 away from the upper umbrella disc 5 is reversibly attached to the fixed sleeve 74 to keep the umbrella surface 2b attached to the sunshade fan structure 99.

[0096] Figure 19 and 20 shows the sunshade fan assembly 100 in a preset open state. For example, the umbrella surfaces 2a, 2b are deployed in the horizontal direction but not in the limit state of the preset open state. In this open state, relative to the preset state of full open, such as Figure 16 and 17 the state shown in, the angles of the positions of the umbrella surfaces 2a, 2b relative to the umbrella rod part 3b are smaller. The sunshade fan assembly 100 disclosed in the present application includes several preset open states. In some embodiments, there are three preset open states. In various preset open states, the position and angle of the attachable fan device 12 relative to the user located under the umbrella surfaces 2a, 2b are different. Therefore, the user can select the open state to choose their favorite wind direction / angle. In various preset open states of the sunshade fan assembly 100, the ventilation openings 8 achieve air circulation above the umbrella surfaces 2a, 2b, so that the attachable fan device 12 can work effectively.

[0097] The control unit 13 is as shown in Figure 16 、 17 、19 and 20. The exemplary control unit 13 includes a body having several buttons 33 and a control circuit 75. The buttons 33 can also be called switches 33. The switches 33 and ports 32 are operably connected to the control circuit 75 of the control unit 13 for controlling the attachable fan device 12. The control circuit 75 is as shown in Figure 28 . As shown in the figure, the control unit 13 also includes a charging port 32, and the user can charge personal electronic devices such as mobile phones and laptops. The control unit 13 can not only charge electronic devices but also operate the attachable fan device 12, making it more convenient for consumers to use.

[0098] Now refer to Figure 21 、 22, 25, 26, 27, and 29, an embodiment of the various components of the electrical wiring system of the patio umbrella fan structure / component 100 is shown in the figure. The electrical wiring system includes an electrical wire 16 and an electrical connector 40. In the example shown in the figure, the electrical wire 16 enters the umbrella pole portion 3a and runs upward to be operably electrically connected to the control circuit 75 of the control unit 13. After being electrically connected to the control circuit 75, the electrical wire 16 continues to run upward within the umbrella pole portion 3b and is electrically connected to the electrical connector 57 of the PCB board 53 of the upper umbrella disk. The internal wiring 82 of the PCB board 53 electrically connects each electrical connector 56 to the electrical connector 57. After the electrical wire 16 is electrically connected to the electrical connector 56, it exits the upper umbrella disk 5 through the opening 54, and then runs within the rib 7 of the strut portion 6a. After the electrical wire 16 exits the rib 7 through the opening 66, it runs within the strut portion 6a and is operably electrically connected to the motor 20 of the attachable fan device. In some embodiments of the present application, the electrical wiring system includes additional electrical connectors 40. For example, the electrical wire 16 entering the umbrella pole portion 3a may be electrically connected to another electrical wire 16 connected to the control circuit 75, and such an electrical connection can be accessed through the opening 43 to facilitate repair when needed. Another example is the electrical connection between the electrical wire 16 exiting the rib 7 through the opening 66 and the electrical wire 16 running within the strut portion 6a, which can be located in a relatively accessible position in an exemplary case to facilitate repair when needed. In some embodiments, the patio umbrella fan assembly 100 includes a plurality of switches 33, each switch 33 being operably connected to an attachable fan device 12, and the electrical wire 16 led out from the control unit 13 includes a plurality of wires, each wire being operably electrically connected to a switch 33. In the present embodiment, the electrical connector 57 includes a plurality of different electrical connectors 40 that match the number of the electrical wires. And each electrical connector 56 is electrically connected to an electrical connector 40 included within the electrical connector 57 through the internal wiring 82. The electrical wire 16 led out from each electrical connector 56 is operably connected to an attachable fan device 12, so that the user can operate to control a selected attachable fan device 12. In the present embodiment, each switch is operably connected to an attachable fan device 12, and the attachable fan device 12 operably connected to the switch 33 is generally located above the switch 33. In some other embodiments, a switch 33 is operably connected to a plurality of attachable fan devices 12, and the electrical wire 16 led out from the control unit 13 includes a number of wires that match the number of the switches 33. Those skilled in the art should understand that all possible electrical wirings should be included within the protection scope of the present application.

[0099] Now refer to Figure 23 , 24, 29. In some embodiments, the electrical circuit system disclosed in the present application includes a safety mechanism that prevents a user from accidentally turning off the parasol fan structure / component 99 / 100 while the attachable fan device 12 is still operating. The safety mechanism disclosed in the present application includes a Hall sensor 77, a Hall sensor base 78, and a magnet 79. In the example herein, the Hall sensor 77 is located within the umbrella pole portion 3b and is fixed by the sensor base 78. The Hall sensor base 78 can be attached to the inside of the umbrella pole portion 3b by any method that can prevent it from moving during use or transportation, etc. Such methods include, but are not limited to, using suitable fastening devices, direct fixing devices, glue, clips, etc. The electrical circuit 16 is electrically connected between the Hall sensor 77 and the electrical connector 58 on the PCB board 53. As shown in the figure, the Hall sensor base 78 can also partially cover the electrical circuit 16 that extends upward within the umbrella pole portion 3b and leads out from the Hall sensor 77. The internal circuit of the PCB board 53 electrically connects the electrical connector 58 and the electrical connector 57. When the electrical connector 58 is driven by the control circuit 75 of the control unit 13, the Hall sensor 77 will also be electrically driven. As Figure 29 shown, the lower umbrella disk 4 includes a magnet 79. In some embodiments, the magnet is located within the lower umbrella disk 4 near its inner circumference, i.e., near the umbrella pole portion 3b. Figure 29 The top cover 80 and the bottom cover 81 of the lower umbrella disk are shown, both of which include openings 60 for the rope 11 to pass through. In some embodiments, the lower umbrella disk 4 of the parasol fan assembly 100 disclosed in the present application is larger than the lower umbrella disks commonly used in the art, which ensures that there is more space between the main umbrella ribs 3a, 3b and the struts 6a, 6b to accommodate the attachable fan device. The size of the lower umbrella disk 4 disclosed in the present application allows for the opening of the opening 60, through which the rope 11 passes instead of passing along its side, enabling the user to vertically pull or release the rope 11, thereby preventing the rope 11 from getting stuck or entangled with the rotating fan blade 17 or any component of the attachable fan device 12. When the Hall sensor 77 is electrically driven and approaches the magnet 79, the electrical connector 57 electrically drives the electrical connector 56, thereby driving the attachable fan device 12. When the Hall sensor 77 is not close to the magnet 79, the power supply of the electrical connector 57 is cut off and the attachable fan device 12 will not be able to operate or will stop working. The Hall sensor 77 is generally located within the umbrella pole portion 3b, so that when the parasol fan structure / component 99 / 100 is in a preset open state, the position of the Hall sensor 77 coincides with the position of the lower umbrella disk 4, thereby allowing the attachable fan device 12 to operate only in these preset open states. In this way, it is possible to avoid accidentally operating the attachable fan device 12 when the parasol fan structure / component 99 / 100 is closed or in a partially closed state, thereby preventing damage to the attachable fan device 12 or any other parts of the parasol fan structure / component 99 / 100.

[0100] In some embodiments, when the magnet 79 and the Hall sensor 77 do not coincide, the Hall sensor 77 cuts off the circuit of the electrical connector 57. In some embodiments, when there is a certain distance between the magnet 79 and the Hall sensor 77, the Hall sensor 77 cuts off the circuit of the electrical connector 57. In some embodiments, the distance is about 0.5 - 30 cm. In some embodiments, the distance is about 1 - 15 cm. In some embodiments, the distance is about 3 - 10 cm. In some embodiments, the distance is about 3, 4, 5, 6, 7, 8, 9, or 10 cm.

[0101] Figures 30 - 33 Schematically shows the electrical circuit system when the parasol fan structure / component 99 / 100 is in the open or partially closed state, including the position of the magnet 79 relative to the Hall sensor 77. Figure 30 Shows the parasol fan structure / component 99 / 100 in a first preset open state, where the lower umbrella disk 4 is fixed at the highest preset position along the umbrella rod part 3b. In the exemplary first preset open state, the magnet 79 and the Hall sensor 77 partially coincide, and the Hall sensor 77 allows the attachable fan device 12 to operate. Figure 31 Shows the parasol fan structure / component 99 / 100 in a second preset open state, where the lower umbrella disk 4 is fixed at the middle preset position along the umbrella rod part 3b. In the exemplary second preset open state, the magnet 79 completely coincides with the Hall sensor 77, and the Hall sensor 77 allows the attachable fan device 12 to operate. Figure 32 Shows the parasol fan structure / component 99 / 100 in a third preset open state, where the lower umbrella disk 4 is fixed at the lowest preset position along the umbrella rod part 3b. In the exemplary third preset open state, the magnet 79 and the Hall sensor 77 partially coincide again, and the Hall sensor 77 allows the attachable fan device 12 to operate. Finally, Figure 33 Shows the parasol fan structure / component 99 / 100 in a partially closed state, which may occur, for example, when the user starts to close the parasol fan assembly 100 and the lower umbrella disk 4 slides down along the umbrella rod part 3b, but may forget to turn off the attachable fan device 12. In the exemplary partially closed state, the magnet 79 no longer coincides with the Hall sensor 77, and the distance between them is such that the Hall sensor 77 cuts off the circuit and pauses the operation of the attachable fan device 12. As the attachable fan device 12 stops operating, the fan blade 17 stops at a position parallel to the support rod parts 6a and 6b.

[0102] Finally, refer to Figure 34, wherein the sun umbrella fan structure 99 disclosed in the present application is in a closed state and the lower umbrella disk 4 is located close to the control unit 13. The umbrella ribs 7 are substantially parallel to the umbrella rod parts 3a and 3b, and the fan blades 17 are parallel to the struts 6a and 6b. Therefore, in the closed state, the fan blades will not be damaged and will not damage any components of the sun umbrella fan structure / assembly 99 / 100.

[0103] In some embodiments, the sun umbrella fan structure / assembly 99 / 100 disclosed in the present application may include wired power transmission and wired control, wireless power transmission and wireless control, a local power source for the attachable fan device 12 and wireless control integrated in the control unit 13, or a local power source for the attachable fan device 12 and wireless control separate from the control unit 13.

[0104] The power transmission and control of the attachable fan device 12 can both be achieved through the electrical circuit 16 as shown here. In this embodiment, the electrical circuit 16 is connected to an AC power source and the control unit 13, and is also connected to the control unit 13 and the attachable fan device 12, thereby supplying power to the attachable fan device 12. The control unit 13 can be controlled by pressing a button or operating a regulator or switch thereon, and then adjusting the control circuit 31 to achieve the control of the attachable fan device 12. In some embodiments, the control circuit 31 can be structurally associated with or integrated into the control unit 13, and can be operably connected to a button or switch of the control unit 13 to operate the control unit 13. In this way, the user can operate the attachable fan device 12 through the control unit 13.

[0105] In some embodiments, power is transmitted to the attachable fan device 12 through the electrical circuit 16 led out from the control unit 13, and the control of the fan device 12 can be achieved by wireless connection (not shown). In various other embodiments, regardless of the power supply method to the attachable fan device 12, the control circuit 31 can be structurally associated with or integrated into the control unit 13, or alternatively, the control circuit 31 can be structurally separated from the control unit 13, or can be separable from the control unit 13, or is different from the control unit 13.

[0106] In the embodiment of controlling the attachable fan device 12 through wireless connection, the control unit 13 can be configured to continuously supply power to the attachable fan device 12. The local control circuit of the attachable fan device 12 can determine the control of the power used by the attachable fan device 12 to operate. The local control circuit is operably connected to a wireless receiver for receiving control signals sent by a wireless transmitter, and the wireless transmitter is operably connected to the control circuit 31, regardless of whether the control circuit 75 is integrated into the control unit 13 or separated from the control unit 13.

[0107] In any embodiment having a wireless connection, the wireless connection for sending and receiving control signals can be implemented through any suitable wireless communication protocol, including but not limited to Bluetooth®, WiFi®, WiFi, infrared transmission, etc. When a start signal for turning on and starting the operation of the attachable fan device 12 is received, the local control circuit of the attachable fan device 12 closes, enabling power to be delivered to the motor and the electric actuator of the attachable fan device 12. When a stop signal for turning off and stopping the operation of the attachable fan device 12 is received, the local control circuit of the attachable fan device 12 opens, causing power to no longer be delivered to the motor and the electric actuator of the attachable fan device 12, thereby causing the fan blade 17 to stop rotating and enter a state aligned with the parasol poles 6a, 6b, as described in the text.

[0108] In at least some embodiments, the electrical line 16 can be used to deliver power from an AC power source to the control unit 13, thereby driving the control circuit 75, and can also serve as a charging power source to charge the local power source of the attachable fan device 12. The local power source can be a battery or a plurality of batteries, such as a rechargeable battery, for example, a rechargeable lithium-ion battery. In the example of using a rechargeable battery, the control unit 13 can include a port for charging the rechargeable battery when not in use, and this port can be a dedicated port or a multi-functional port. Similarly, if the wireless controller has a control circuit, then the wireless controller may need to be charged, and the control unit 13 can have a port for charging it, and this port can be a dedicated port or a multi-functional port.
