[0016] In order to make the above-mentioned objects, features and advantages of the present invention more clearly comprehensible, the following detailed description of specific embodiments of the present invention will be given with reference to the accompanying drawings. In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can be implemented in many ways other than those described herein, and those skilled in the art can make similar modifications without departing from the spirit and scope of the present invention, so the present invention is not limited by the specific embodiments disclosed below. [Example]

[0017] Example 1 1 to 7, the present invention discloses an umbrella handle with a fan structure that can blow air into the space under the umbrella and is safe to use, and is used to attach to a parasol. The umbrella handle comprises a hollow rod 100, a handle 200 fixed to the bottom of the hollow rod 100, and a blower unit 300 fixed to the top of the hollow rod 100. The hollow rod 100 supports the parasol ribs and provides an attachment point for the handle 200 and the blower unit 300. The handle 200 provides a grip for the user when holding the parasol. The blower unit 300 mixes the air above the hollow rod 100 to blow air to the user's head and face. The blower unit 300 comprises a casing 310 having a hollow columnar structure, a fan 320 housed in the inner cavity of the casing 310, and a wind guide structure 330. The cross section of the casing may be circular, elliptical, polygonal, or irregular, as long as it is a hollow structure extending in the axial direction of the hollow rod. By packaging and installing the fan 320 within the casing 310, the fan blades of the fan 320 are prevented from coming into contact with the user's hair or other thread-like or rod-like objects on the head, thereby improving the safety of using the fan 320. The casing 310 is fixedly connected to and communicates with the hollow rod 100, and the upper part of the air guide structure 330 communicates with the lower region of the fan 320. The lower part of the air guide structure 330 is bent, forming a corresponding guide outlet 331 on one side of the inner wall of the casing 310. An air intake 311 is provided at the top of the casing 310, corresponding to the fan 320 and communicating with the inner cavity of the casing 310. There are three cases where an air intake 311 is provided at the top of the casing 310: when the air intake is provided on the top surface of the casing, when the air intake is provided on the ring-shaped side surface of the top of the casing, and when the air intake is provided on both the top surface and the top ring-shaped side surface of the casing. In this embodiment, the case where the air intake is provided on the top surface of the casing has been mainly described, but the case where the air intake is provided on the ring-shaped side surface of the top of the casing is also covered by the present invention. An air outlet 312 that communicates with a guide outlet 331 is provided on the bottom ring-shaped side surface of the casing 310.In this way, when fan 320 is operated, the fan blades of fan 320 agitate the air within casing 310, causing the air to flow rapidly within casing 310 and lowering the air pressure within casing 310. A pressure difference exists between the inside and outside of casing 310, causing air above casing 310 to enter the cavity of casing 310 through air intake 311, then flow further along the cavity of air guide structure 330, and finally pass through guide outlet 331 and exit air outlet 312 on the lower side wall of casing 310, delivering air to the user's head or face. A battery 400 and a control board 500 electrically connected to battery 400 are provided within handle 200, and a button 510 connected to control board 500 is provided on the surface of handle 200. Control board 500 is electrically connected to fan 320 via lead wires routed within hollow rod 100. In other words, the hollow rod 100 supports the remaining components, and the inner cavity of the hollow rod 100 functions as a wiring path between the control board 500 and the fan 320, preventing the lead wires from being exposed and protecting them. In this embodiment, the button 510 is linked to a switch on the control board 500, and pressing the button 510 triggers the operation of the switch on the control board 500 to start and stop the fan 320. Depending on the user's usage habits, the button 510 can be provided on the ring-shaped side surface or end surface of the handle 200, and an opening for passing the button 510 through can be provided on the ring-shaped side surface or end surface of the handle 200.

[0018] The umbrella handle with the fan structure described above has a hollow rod 100 to which a blower unit 300, consisting of a casing 310, a fan 320, and an air guide structure 330, is fixed. A battery 400 installed in the handle 200 supplies power to the fan 320, which can be activated by pressing a button 510 on the handle 200 to blow air to the user in the space below the umbrella, alleviating the discomfort the user feels when holding the umbrella on a hot day. By housing the fan 320 within the casing 310 and directing airflow through the lower sidewall of the casing 310 via the air guide structure 330 to blow air toward the user from the side of the umbrella handle, safety hazards caused by the fan blades of the fan 320 being exposed and causing hair or other objects to get caught in the fan blades can be avoided, improving the safety of the parasol air guide unit 300.

[0019] In one embodiment, the fan 320 includes a fan sleeve 321, a hub 322 accommodated in the fan sleeve 321, a plurality of fan blades 323, and a motor 324 positioned below the fan sleeve 321 and fixedly connected to the fan sleeve 321, the plurality of fan blades 323 being evenly distributed along the ring-shaped side surface of the hub 322 and fixedly connected to the hub 322, the motor 324 being electrically connected to the control board 500, and an output shaft of the motor 324 being drivingly connected to the hub 322. The fan sleeve 321 is fixedly connected to the casing 310 to realize the positioning and mounting of the fan 320 relative to the casing 310. When the motor 324 is driven by the control board 500, the output shaft of the motor 324 rotates the hub 322, which in turn rotates the fan blades 323, stirring the air around the fan blades 323, increasing the air flow velocity around the fan blades 323, and reducing the air pressure around the fan blades 323. This creates a pressure difference between the inside and outside of the casing 310, causing the air above the casing 310 to enter the inner cavity of the casing 310 through the air intake 311 due to the pressure difference. In this embodiment, the fan sleeve 321 guides the air flowing in from the air intake end of the fan 320, defines the airflow path from the air intake end to the air exhaust end of the fan 320, and guides the airflow to the inlet of the air guidance structure 330. In addition, the surface of the hub 322 adjacent to the air intake 311 is spherical or ellipsoidal. This allows the hub 322 to reduce resistance to the airflow entering the inner cavity of the casing 310 through the air intake 311. Furthermore, in this embodiment, the motor 324 is fixedly connected to the inner wall of the fan sleeve 321 via a plurality of connecting bars 325 distributed on the ring-shaped side of the motor 324, thereby realizing the installation of the motor 324 inside the fan sleeve 321 and at the same time, the gaps between the connecting bars 325 become passages for the airflow, ensuring smooth airflow.

[0020] The hollow rod 100 comprises a lower rod 110 positioned at the bottom of the casing 310 and an upper rod 120 positioned at the top of the casing 310, and the lower rod 110 is for inserting lead wires connecting the control board 500 and the fan 320. The casing 310 includes a first part 313 and a second part 314 located above the first part 313 and fixedly connected to the first part 313. The first part 313 includes a cylindrical body 3131 and a first connecting pipe 3132 fixed to the bottom of the cylindrical body 3131 and communicating with the inner cavity of the cylindrical body 3131. The first connecting pipe 3132 is inserted into the top of the lower rod 110 and fixedly connected to the lower rod 110. A first through hole is provided in the lower ring-shaped side of the cylindrical body 3131. At least one grill 3133 is fixed to the first through hole, dividing the first through hole and forming at least two air outlets 312. In this embodiment, the bottom edge of the cylindrical body 3131 is chamfered or rounded to prevent the user from scratching the bottom of the cylindrical body 3131. A ring is fixed to the inside surface of the bottom of the cylindrical body 3131, and a first connecting pipe 3132 is fixedly connected to the underside of the ring, with the inner cavity of the first connecting pipe 3132 communicating with the inner space of the ring and the inner cavity of the cylindrical body 3131. It can be seen that the cylindrical body 3131, the ring, and the first connecting pipe 3132 together form a hollow stepped shaft structure, which allows the first section 313 to fit and connect to the lower rod 110 and also provides a large mounting space for the fan 320 and the air guide structure 330. Furthermore, the cylindrical body 3131, the ring, and the first connecting pipe 3132 are integrally molded to enhance the structural stability of the first section 313, and the first connecting pipe 3132 is threadedly connected to the lower rod 110. In this embodiment, depending on the needs of the appearance design of the umbrella handle, the projection of the opening of the first through hole onto a vertical plane may be any shape such as a circle, a rectangle, an ellipse, a heart, a regular pentagon, a regular hexagon, a flower, etc., or may be any other shape, and the grill 3133 for separating the first through hole may be a striped grid or a mesh grid.The grille 3133 may include a middle block and a plurality of spokes surrounding the middle block and fixedly connected to the ring-shaped side surface of the middle block, each spoke being fixed to the inner wall of the first through-hole. If the grille 3133 is a bar grille, it is necessary to provide a plurality of bar grilles in the first through-hole in order to reduce the size of the air outlet 312. In this embodiment, by providing the grille 3133 in the first through-hole, it is possible to avoid the problem of an external object entering the cylindrical body 3131 through the air outlet 312 and locking the fan 320. In addition, by diverting the airflow blown out by the fan 320 with the grille 3133, it is possible to reduce the impact of the airflow on the user's head and face, thereby improving comfort when the user cools their head using a parasol. In this embodiment, air outlets 312 are provided only in a partial area of ​​the lower ring-shaped side surface of cylinder 3131, so that when the user uses the parasol, they can turn the handle of the umbrella to have air blowing unit 300 blow air only to their face or a specified area on their face. The air blown out from fan 320 is concentrated on the user's face or the specified area on their face, reducing airflow loss and improving the efficiency with which air blowing unit 300 cools the user's face or the specified area on their face.

[0021] The second part 314 includes an inner tube 3141 inserted into the top of the cylindrical body 3131 and fixedly connected to the cylindrical body 3131, an attachment plate 3142 fixed to the top of the inner tube 3141, and a second connecting pipe 3143 located above the attachment plate 3142 and fixedly connected to the middle of the attachment plate 3142, and the attachment plate 3142 has a plurality of second through holes on the ring-shaped side of the second connecting pipe 3143 to form the air intake 311, and the second connecting pipe 3143 is inserted into the bottom of the upper rod 120 and fixedly connected to the upper rod 120. In this embodiment, the inner tube 3141 and the cylindrical body 3131 are fastened together by screws, and the inner tube 3141, the mounting plate 3142, and the second connecting pipe 3143 are integrally molded, improving the structural stability of the second section 314, and the second connecting pipe 3143 is screwed to the upper rod 120. In addition, the edge of the ring-shaped side surface of the mounting plate 3142 protrudes from the inner tube 3141 and forms a first limit ring 3144 that abuts against the upper surface of the cylindrical body 3131. The abutment between the lower surface of the first limit ring 3144 and the upper surface of the cylindrical body 3131 achieves primary positioning of the inner tube 3141 and the cylindrical body 3131 in the axial direction of the hollow rod 100, and determines the insertion depth of the inner tube 3141 into the cylindrical body 3131. At least one positioning block 3145 is provided on the lower surface of the first limit ring 3144, and at least one positioning notch 3134 that fits into each positioning block 3145 is provided on the upper surface of the cylindrical body 3131. Preferably, two positioning blocks 3145 are provided symmetrically on the lower surface of the first limit ring 3144, and two positioning notches 3134 are provided on the upper surface of the cylindrical body 3131 in a one-to-one correspondence with each positioning block 3145. The recessed and protruding engagement between the positioning blocks 3145 and the positioning notches 3134 realizes secondary positioning of the inner tube 3141 and the cylindrical body 3131 in the axial direction of the hollow rod 100, while also realizing positional regulation of the inner tube 3141 and the cylindrical body 3131 along the radial direction of the hollow rod 100, preventing the inner tube 3141 from rotating relative to the cylindrical body 3131. The corresponding hole positions of the inner tube 3141 and the cylindrical body 3131 are aligned, and the inner tube 3141 and the cylindrical body 3131 can be quickly fixed with screws.In this embodiment, the shape of the central portion of the lower surface of mounting plate 3142 matches the shape of the surface adjacent to intake port 311 of hub 322, and it is preferable that the surface adjacent to intake port 311 of hub 322 is an ellipsoid. A concave surface corresponding to the ellipsoid shape is provided in the central portion of the lower surface of mounting plate 3142, and this concave surface is intended to avoid positioning when hub 322 rotates and to prevent misalignment when hub 322 rotates.

[0022] In one embodiment, the air guide structure 330 includes an air guide duct 332 fitted onto the outside of the fan sleeve 321, a second limit ring 333 fitted onto the top of the air guide duct 332 and fixedly connected to the outer ring-shaped side surface of the air guide duct 332, and an inclined deflector 334 fixed to the bottom of the air guide duct 332 and installed at an angle, the bottom of the inner cylinder 3141 abutting against the upper surface of the second limit ring 333, a guide outlet 331 located above the bottom of the inclined deflector 334 is provided on the side wall of the air guide duct 332, and a wiring port 335 corresponding to the motor 324 is provided in the area above the top of the inclined deflector 334 on the side wall of the air guide duct 332. In this embodiment, the provision of second limit ring 333 allows the positioning of the bottom of inner cylinder 3141. Furthermore, when air guide structure 330 is assembled with cylindrical body 3131, the outer ring-shaped side of second limit ring 333 abuts against the inner surface of cylindrical body 3131, forming a gap between the outer ring-shaped side of air guide duct 332 and the inner surface of cylindrical body 3131. This gap is used to provide a passage for the wires leading from wire connection port 335 to motor 324 and control board 500. Sloped deflector 334 guides airflow to one side of the lower part of cylindrical body 3131 and discharges it from air outlet 312. While providing a deflector, the slope of sloped deflector 334 is extended, reducing resistance to the airflow and reducing airflow loss.

[0023] Furthermore, in this embodiment, at least one guide bar 336 is provided on the outer ring-shaped side surface of the air guide duct 332, and at least one guide groove 3135 is provided on the inner surface of the cylindrical body 3131 in sliding contact with each guide bar 336 in a one-to-one correspondence. This guide groove 3135 may be a through groove provided on the inner surface of the cylindrical body 3131 and extending in the height direction of the cylindrical body 3131, or two strip-shaped structures provided opposite each other on the inner surface of the cylindrical body 3131 and extending in the height direction of the cylindrical body 3131 may be fixed, and the gap between the two strip-shaped structures may form this guide groove 3135. When assembling the air guide structure 330 and the cylindrical body 3131, the air guide structure 330 and the cylindrical body 3131 can be assembled by inserting the guide bar 336 into the guide groove 3135 and bringing the cylindrical body 3131 close to the air guide structure 330, and the air guide structure 330 and the cylindrical body 3131 can be quickly aligned. By aligning the guide outlet 331 with the air outlet 312, it is possible to prevent rotation of the cylindrical body 3131 relative to the air guide structure 330, improving the efficiency of assembling the air guide structure 330 and the cylindrical body 3131. A support portion 337 that abuts against the bottom of the fan sleeve 321 is provided on the inner ring-shaped side surface of the air guide duct 332, and a pressure contact portion 3146 that abuts against the top of the fan sleeve 321 is provided on the inner surface of the inner cylinder 3141. In this way, the common definition of the support portion 337 and the pressure contact portion 3146 makes it possible to position the fan sleeve 321 relative to the air guide duct 332 and the inner cylinder 3141, preventing rattling of the fan sleeve 321 relative to the air guide duct 332 and the inner cylinder 3141.

[0024] Depending on the user's usage habits, the handle 200 may be straight or bent. FIG. 1 shows the handle structure of an umbrella when the handle 200 is straight, and FIG. 8 shows the handle structure of an umbrella when the handle 200 is bent. When the handle 200 is bent, the user can grasp the bent portion of the bent handle and place the bent portion in contact with the palm of their hand, improving the comfort of holding the handle 200. The bent handle can also be hooked onto an external object to position the parasol. When the handle 200 is straight, a strap 210 may be fixed to the handle 200, and the user can position the parasol by passing their wrist through the strap 210 or by hanging the strap 210 on an external object. Furthermore, when the handle 200 is straight, an opening is provided at the bottom of the handle 200, and an openable end cap is attached to the opening. The end cap presses against the battery 400, thereby positioning the battery 400. When the battery 400 runs out, the end cap can be opened to replace the battery 400. Furthermore, the end cap is screwed onto the inner wall of the handle 200, making it easy to attach and detach the end cap. [Example]

[0025] Example 2 1 to 7 and 9 to 10, the present invention discloses a parasol including an umbrella handle with the above-mentioned fan structure, and the parasol further includes a first umbrella rib 600, a second umbrella rib 700 located below the first umbrella rib 600 and supporting the first umbrella rib 600, a first movable connecting ring 610, a second movable connecting ring 710, and an umbrella cloth 800 covering the surface of the first umbrella rib 600, and the ring-shaped side of the first movable connecting ring 610, the top of the first umbrella rib 600, The top of the second umbrella bone 700 is hingedly connected to the middle of the first umbrella bone 600, and the bottom of the second umbrella bone 700 is hingedly connected to the ring-shaped side of the second movable connecting ring 710. The hollow rod 100 passes through the first movable connecting ring 610 and the second movable connecting ring 710 in that order, and the top of the hollow rod 100 is fixedly connected to the first movable connecting ring 610, with the upper part of the hollow rod 100 sliding against the inner wall of the second movable connecting ring 710. In this embodiment, the structure of the umbrella handle is exactly the same as that of the umbrella handle in Example 1. The specific structure of the umbrella handle can be referred to in the relevant description of Example 1, so a detailed description will be omitted here.

[0026] In this embodiment, the second movable connecting ring 710 is located below the blower unit 300, and the inner diameter of the second movable connecting ring 710 is smaller than the outer diameter of the first connecting pipe 3132. Thus, when the upper body of the second rib 700 is moved and rotated, the second movable connecting ring 710 rises until it abuts the bottom surface of the first connecting pipe 3132 and cannot rise any further. This prevents the second movable connecting ring 710 from colliding with the blower unit 300 and also prevents the first rib 600 from bending and turning away from the second rib 700 due to the second movable connecting ring 710 rising too far. A sleeve is also provided at the bottom of the second movable connecting ring 710, and a guide hole corresponding to the sleeve is provided in the lower rod 110 of the hollow rod 100. A pressing piece is inserted into this guide hole, and the lower part of the pressing piece is elastically connected to the lower rod 110. When the parasol is in use, the second movable connecting ring 710 is pressed, causing the second movable connecting ring 710 to lift the second rib 700. At the same time, the hinged connections between the second rib 700 and the first rib 600, and the hinged connections between the first rib 600 and the first movable connecting ring 610, cause the first rib 600 and the second rib 700 to swing simultaneously, unfolding the umbrella cloth 800. When the sleeve slides until it comes into contact with the pressing piece, the inner wall of the sleeve presses against the pressing piece, causing the pressing piece to retract into the guide hole, and the sleeve continues to rise following the second movable connecting ring 710. When the sleeve rises until it is separated from the pressing piece, the sleeve releases the pressing piece from its restraint, and the pressing piece springs back to abut against the lower end surface of the sleeve, thereby positioning the sleeve, second movable connecting ring 710, first rib 600, and second rib 700, and preventing the parasol from closing on its own due to external impact.

[0027] In another embodiment, a locking hole is provided on the lower rod 110, a strip-shaped hole is provided on the outer wall of the sleeve 720, two lugs are provided on both sides of the outer edge of the strip-shaped hole, and a pressing element 730 is provided between the two lugs. The pressing element 730 is pivotally attached to the two lugs and elastically connected to the outer wall of the sleeve 720. A locking block corresponding to the locking hole is provided on the inner surface of the pressing element 730. When the locking block of the sleeve 720 is raised to the same height as the locking hole, the locking block fits into the locking hole through the strip-shaped hole, thereby realizing mutual restraint between the lower rod 110 and the sleeve 720. When the upper part of the pressing element 730 is pressed, the locking block is lifted and separated from the locking hole, releasing the restraint of the sleeve 720 by the lower rod 110. The sleeve 720 then lowers, and the parasol is retracted. Of course, in actual design, the limit structure between the sleeve 720 and the lower rod 110 may be the positioning structure of other umbrella handles available on the market, but the description thereof will be omitted here.

[0028] The parasol described above has a blower unit 300, consisting of a casing 310, a fan 320, and an air guide structure 330, fixed to a hollow rod 100. A battery 400 is installed in the handle 200 to power the fan 320. Pressing a button 510 on the handle 200 activates the fan 320, blowing air to the user in the space below the umbrella, alleviating the discomfort the user may feel when holding the umbrella on a hot day. By housing the fan 320 within the casing 310 and using the air guide structure 330 to direct airflow from the lower sidewall of the casing 310 and blow air toward the user from the side of the umbrella handle, this prevents safety accidents caused by the fan blades 323 of the fan 320 being exposed, which could result in the user's hair or other objects getting caught in the fan blades 323, thereby improving the safety of the parasol's air guide unit 300.

[0029] The technical features of the above-described embodiments can be combined in any desired manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments will be described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
