[0002] A parasol is an outdoor sunshade product used to shield users from direct sunlight, provide shade, and prevent ultraviolet radiation damage, thus improving the comfort of users during outdoor activities or rest. However, most parasols on the market only provide sun protection. In hot summers, especially in windless or lightly breezy environments, even with the parasol providing shade, the space under the umbrella still accumulates heat due to poor air circulation, leading to stuffiness and discomfort. Users exposed to this high-temperature, poorly ventilated environment for extended periods are prone to discomfort such as sweating, irritability, and may even experience heatstroke and other health problems. To address this issue, Chinese invention patent application (CN201711395162.X) discloses a cooling parasol that uses an electric fan mounted on the handle to provide a cooling breeze under the umbrella in hot summers. However, in this parasol, the fan blades are mostly exposed, making it easy for users to have their hair or other long or thin objects from their head caught in the fan blades, potentially causing accidents. Therefore, this parasol lacks sufficient safety features. Utility Model Content

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] Example 1

[0027] Please combine Figure 1-7This utility model discloses an umbrella handle with a fan structure that can deliver air to the space under the umbrella and is safe to use. The umbrella handle is used to install on a parasol and includes a hollow pole 100, a handle 200 fixed to the bottom of the hollow pole 100, and an air delivery assembly 300 fixed to the upper part of the hollow pole 100. The hollow pole 100 supports the umbrella ribs and provides the mounting part for the handle 200 and the air delivery assembly 300. The handle 200 provides a grip for the user when holding the parasol. The air delivery assembly 300 delivers air to the user's head and face by agitating the air in the upper part of the hollow pole 100. The air delivery assembly 300 includes a hollow cylindrical shell 310 and a fan 320 and an air guide structure 330 housed in the inner cavity of the shell 310. The cross-section of the shell can be circular, elliptical, polygonal, or irregular, as long as the shell is a hollow structure extending along the axial direction of the hollow pole. Encapsulating the fan 320 with the outer casing 310 prevents the fan blades from coming into contact with the user's hair or other hair-like or fibrous materials, thus improving the safety of using the fan 320. The outer casing 310 is fixedly connected to and communicates with the hollow rod 100. The upper part of the air guide structure 330 communicates with the lower part of the fan 320. The lower part of the air guide structure 330 is bent to form a guide outlet 331 corresponding to one side of the inner wall of the outer casing 310. The top of the outer casing 310 has an air inlet 311 corresponding to the fan 320 and communicating with the inner cavity of the outer casing 310. The air inlet 311 on the top of the outer casing 310 includes three cases: first, the air inlet is opened on the top surface of the outer casing; second, the air inlet is opened on the upper ring side of the outer casing; and third, the air inlets are opened on both the top surface and the upper ring side of the outer casing. This embodiment focuses on describing the case where the air inlet is opened on the top surface of the outer casing; however, the case where the air inlet is opened on the upper ring side of the outer casing is still within the scope of protection of this utility model. The lower ring side of the outer casing 310 has an air outlet 312 that communicates with the guide outlet 331. Thus, when the fan 320 is working, the fan blades of the fan 320 agitate the air inside the outer casing 310, causing the air inside the outer casing 310 to flow rapidly, thereby reducing the air pressure inside the outer casing 310. There is an air pressure difference between the inside and outside of the outer casing 310. The air above the outer casing 310 enters the inner cavity of the outer casing 310 through the air inlet 311 under the action of the air pressure difference, and further flows along the inner cavity of the air guide structure 330. Finally, it is blown out from the air outlet 312 on the lower side wall of the outer casing 310 through the guide outlet 331 to deliver air to the user's head or face. The handle 200 contains a battery 400 and a control circuit board 500 electrically connected to the battery 400. The surface of the handle 200 has buttons 510 connected to the control circuit board 500. The control circuit board 500 is electrically connected to the fan 320 through wires laid inside the hollow rod 100. In other words, while supporting the other components, the hollow rod 100 also serves as a wiring channel between the control circuit board 500 and the fan 320 to avoid exposed wires and protect them.In this embodiment, button 510 cooperates with a switch on control circuit board 500. By pressing button 510, the switch on control circuit board 500 can be triggered to start and stop fan 320. Depending on the user's different usage habits, button 510 can be set on the ring side or end face of handle 200, and a switch opening for button 510 to pass through is opened on the ring side or end face of handle 200.

[0028] The aforementioned umbrella handle with a fan structure has an air supply assembly 300 consisting of a housing 310, a fan 320, and an air guide structure 330 fixed on the hollow shaft 100. A battery 400 is installed inside the handle 200 to power the fan 320. The fan 320 can be started by pressing the button 510 on the handle 200 and air is supplied to the user located in the space under the umbrella, thereby improving the user's discomfort when holding the umbrella in hot weather. The fan 320 is housed inside the housing 310 and the air is guided by the air guide structure 330 from the lower side wall of the housing 310 to supply air to the user from the side of the umbrella handle. This avoids the safety problem caused by the user's hair or other objects being tangled on the fan blades due to the exposed fan blades of the fan 320, thereby improving the safety of using the sun umbrella air supply assembly 300.

[0029] In one embodiment, the fan 320 includes a fan sleeve 321, a hub 322 housed within the fan sleeve 321, a plurality of fan blades 323, and a motor 324 located below the fan sleeve 321 and fixedly connected to the fan sleeve 321. The plurality of fan blades 323 are evenly distributed along the circumferential side of the hub 322 and fixedly connected to the hub 322. The motor 324 is electrically connected to the control circuit board 500, and the output shaft of the motor 324 is drivenly connected to the hub 322. The fan sleeve 321 is fixedly connected to the housing 310 to achieve the positioning and installation of the fan 320 on the housing 310. When the motor 324 operates under the drive of the control circuit board 500, the output shaft of the motor 324 drives the hub 322 to rotate. The hub 322 further drives multiple fan blades 323 to rotate, thereby agitating the air around the fan blades 323, accelerating the airflow 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 housing 310, allowing the gas above the housing 310 to enter the inner cavity of the housing 310 through the air inlet 311 under the action of the pressure difference. In this embodiment, the fan sleeve 321 is used to guide the air flowing in from the air inlet of the fan 320, thereby limiting the airflow path from the air inlet to the air outlet of the fan 320 and guiding the airflow to the inlet of the air guide structure 330. In addition, the side of the hub 322 adjacent to the air inlet 311 is a spherical or ellipsoidal surface, which reduces the resistance of the hub 322 to the airflow entering the inner cavity of the housing 310 through the air inlet 311. Furthermore, in this embodiment, the motor 324 is fixedly connected to the inner wall of the fan sleeve 321 by a plurality of connecting strips 325 distributed on the circumferential side of the motor 324. In this way, while the motor 324 is installed in the fan sleeve 321, the gaps between the connecting strips 325 provide a channel for airflow to pass through, so as to ensure smooth airflow.

[0030] The hollow rod body 100 includes a lower rod body 110 located at the lower part of the outer shell 310 and an upper rod body 120 located at the upper part of the outer shell 310. The lower rod body 110 is used to pass through the wires connecting the control circuit board 500 and the fan 320. The outer shell 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 body 110 and fixedly connected to the lower rod body 110. A first through hole is opened on the lower circumferential side of the cylindrical body 3131. At least one grille 3133 is fixed at the first through hole to separate the first through hole and form at least two air outlets 312. In this embodiment, the bottom edge of the cylinder 3131 is chamfered or rounded to prevent the user from being scratched by the bottom of the cylinder 3131. A ring is fixed to the inner side of the bottom of the cylinder 3131. The first connecting pipe 3132 is fixedly connected to the lower surface of the ring, and the inner cavity of the first connecting pipe 3132 communicates with the inner space of the ring and the inner cavity of the cylinder 3131. It can also be understood that the cylinder 3131, the ring, and the first connecting pipe 3132 together form a hollow stepped shaft structure, so as to provide a larger installation space for the fan 320 and the air guide structure 330 while the first part 313 is adapted to be connected to the lower rod 110. Furthermore, the cylinder 3131, the ring, and the first connecting pipe 3132 are integrally formed to improve the structural stability of the first part 313. The first connecting pipe 3132 is screwed to the lower rod 110. It should be noted that, in this embodiment, depending on the different appearance design requirements of the umbrella handle, the projection of the opening of the first through hole in the vertical plane can be one of the following shapes: circle, rectangle, ellipse, heart, regular pentagon, regular hexagon, flower, etc., or other shapes. The grille 3133 used to separate the first through hole is a strip grille or a mesh grille. The grille 3133 may also include a central block and multiple spokes surrounding the central block and fixedly connected to the annular side of the central block. Each spoke is fixedly connected to the inner wall of the first through hole. When the grille 3133 is a strip grille, multiple strip grilles need to be set at the first through hole to reduce the size of the air outlet 312. In this embodiment, by setting the grille 3133 at the first through hole, the problem of the fan 320 being blocked due to external objects entering the cylinder 3131 through the air outlet 312 can be avoided. In addition, by diverting the airflow blown out by the fan 320 through the grille 3133, the impact of the airflow on the user's head and face can be reduced, improving the user's comfort when using the parasol for cooling.In addition, in this embodiment, the air outlet 312 is only opened in a part of the lower circumferential side of the cylinder 3131. In this way, when the user uses the parasol, he / she can turn the umbrella handle so that the air supply component 300 delivers air to his / her face or a designated area on his / her face. The air blown by the fan 320 is concentrated on the user's face or a designated area on his / her face, with less air volume loss, which improves the cooling efficiency of the air supply component 300 on the user's face or a designated area on his / her face.

[0031] The second part 314 includes an inner cylinder 3141 inserted into the top of the cylinder 3131 and fixedly connected to the cylinder 3131, a mounting plate 3142 fixed to the top of the inner cylinder 3141, and a second connecting pipe 3143 located above the mounting plate 3142 and fixedly connected to the middle of the mounting plate 3142. The mounting plate 3142 has multiple second through holes on the circumferential side of the second connecting pipe 3143 to form an air inlet 311. 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 cylinder 3141 and the cylinder 3131 are fixedly connected by screws. The inner cylinder 3141, the mounting plate 3142, and the second connecting pipe 3143 are integrally formed to improve the structural stability of the second part 314. The second connecting pipe 3143 is screwed to the upper rod 120. In addition, the annular edge of the mounting plate 3142 protrudes from the inner cylinder 3141 to form a first limiting ring 3144 that abuts against the top surface of the cylinder 3131. Through the abutment between the lower surface of the first limiting ring 3144 and the top surface of the cylinder 3131, the inner cylinder 3141 and the cylinder 3131 are positioned along the axial direction of the hollow rod 100, which limits the depth of the inner cylinder 3141 inserted into the cylinder 3131. The lower surface of the first limiting ring 3144 is provided with at least one positioning block 3145, and the top surface of the cylinder 3131 is provided with at least one positioning notch 3134 that corresponds to and mates with each positioning block 3145. Preferably, two positioning blocks 3145 are symmetrically arranged on the lower surface of the first limiting ring 3144, and two positioning notches 3134 corresponding to each positioning block 3145 are opened on the top surface of the cylinder 3131. In this way, through the concave-convex cooperation between the positioning blocks 3145 and the positioning notches 3134, on the one hand, the inner cylinder 3141 and the cylinder 3131 are positioned axially along the hollow rod 100, and on the other hand, the inner cylinder 3141 and the cylinder 3131 are limited radially along the hollow rod 100, preventing the inner cylinder 3141 from rotating relative to the cylinder 3131, so that the corresponding holes on the inner cylinder 3141 and the cylinder 3131 are aligned, thereby quickly fixing the inner cylinder 3141 and the cylinder 3131 together with screws. In this embodiment, the shape of the middle part of the lower surface of the mounting plate 3142 is adapted to the shape of the side of the hub 322 adjacent to the air inlet 311. Preferably, the side of the hub 322 adjacent to the air inlet 311 is an ellipsoid. The middle part of the lower surface of the mounting plate 3142 is provided with a concave surface whose shape is adapted to the shape of the ellipsoid. The concave surface is used to avoid the hub 322 from rotating, so as to prevent the mounting plate 3142 from interfering with the rotation of the hub 322.

[0032] In one embodiment, the air guide structure 330 includes an air guide duct 332 sleeved on the outside of the fan sleeve 321, a second limiting ring 333 sleeved on the top of the air guide duct 332 and fixedly connected to the outer ring side of the air guide duct 332, and an inclined guide plate 334 fixed to the bottom of the air guide duct 332 and inclinedly arranged. The bottom end of the inner cylinder 3141 abuts against the upper surface of the second limiting ring 333. The side wall of the air guide duct 332 is provided with a guide outlet 331 located above the bottom end of the inclined guide plate 334. The side wall of the air guide duct 332 is provided with a wiring port 335 corresponding to the motor 324 in the area above the top of the inclined guide plate 334. In this embodiment, the bottom end of the inner cylinder 3141 can be positioned by setting the second limiting ring 333. In addition, when the air guide structure 330 is assembled with the cylinder 3131, the outer ring side of the second limiting ring 333 abuts against the inner side of the cylinder 3131, thereby forming a gap between the outer ring side of the air guide pipe 332 and the inner side of the cylinder 3131. This gap provides a passage for the wires leading out from the wiring port 335 and connecting the motor 324 and the control circuit board 500. The inclined guide plate 334 is used to guide the airflow to the lower side of the cylinder 3131 and out through the air outlet 312. While achieving airflow guidance, the inclined extension of the inclined guide plate 334 can reduce airflow resistance, thereby reducing airflow loss.

[0033] Furthermore, in this embodiment, the outer ring side of the air duct 332 is provided with at least one guide strip 336, and the inner surface of the cylinder 3131 is provided with at least one guide groove 3135 corresponding to each guide strip 336 and slidingly engaging with each guide strip 336. The guide groove 3135 can be a through groove opened on the inner surface of the cylinder 3131 and extending along the height direction of the cylinder 3131, or it can be two strip structures fixedly arranged opposite each other on the inner surface of the cylinder 3131 and extending along the height direction of the cylinder 3131. The gap between the two strip structures forms the guide groove 3135. When assembling the air guide structure 330 and the cylinder 3131, the guide strip 336 is inserted into the guide groove 3135 and the cylinder 3131 is pushed close to the air guide structure 330. This allows for the assembly of the air guide structure 330 and the cylinder 3131, enabling quick alignment of the air guide structure 330 and the cylinder 3131, as well as alignment of the guide outlet 331 and the air outlet 312. It also prevents the cylinder 3131 from rotating relative to the air guide structure 330, thus improving the assembly efficiency of the air guide structure 330 and the cylinder 3131. The inner ring side of the air duct 332 is provided with a support portion 337 that abuts against the bottom end of the fan sleeve 321, and the inner surface of the inner cylinder 3141 is provided with a pressing portion 3146 that abuts against the top end of the fan sleeve 321. In this way, the fan sleeve 321 can be positioned on the air duct 332 and the inner cylinder 3141 by the joint constraint of the support portion 337 and the pressing portion 3146, so as to prevent the fan sleeve 321 from moving relative to the air duct 332 and the inner cylinder 3141.

[0034] Depending on the user's different usage habits, handle 200 can be either a straight handle or a curved handle. Figure 1 The umbrella handle structure is shown when the handle 200 is a straight handle. Figure 8 The diagram illustrates the umbrella handle structure when the handle 200 is curved. When the handle 200 is curved, the user can grip the bent portion of the handle, allowing it to contact the palm of the hand, thus improving the comfort of holding the handle 200. The curved handle can also be hung on an external object for positioning the umbrella. When the handle 200 is straight, a collar 210 can be fixed to the handle 200. The user can position the umbrella by passing their wrist through the collar 210 or by hanging the collar 210 on an external object. Additionally, when the handle 200 is straight, the bottom of the handle 200 has an opening, and an openable end cap is fitted over the opening. The end cap presses against the battery 400, positioning the battery 400. When the battery 400 is depleted, the end cap can be opened to replace the battery. Furthermore, the end cap is threaded to the inner wall of the handle 200 to reduce the difficulty of assembling and disassembling the end cap.

[0035] Example 2

[0036] Please combine Figure 1-7 and Figure 9-10 This utility model also discloses a parasol, which includes the aforementioned umbrella handle with a fan structure. The parasol also includes a first umbrella rib 600, a second umbrella rib 700 located below the first umbrella rib 600 and used to support the first umbrella rib 600, a first movable connecting ring 610, a second movable connecting ring 710, and an umbrella fabric 800 covering the surface of the first umbrella rib 600. The ring side of the first movable connecting ring 610 is hinged to the top end of the first umbrella rib 600, the top end of the second umbrella rib 700 is hinged to the middle part of the first umbrella rib 600, and the bottom end of the second umbrella rib 700 is hinged to the ring side of the second movable connecting ring 710. A hollow rod 100 passes sequentially through the first movable connecting ring 610 and the second movable connecting ring 710, and the top end of the hollow rod 100 is fixedly connected to the first movable connecting ring 610. The upper part of the hollow rod 100 is slidably engaged with 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 Embodiment 1. The specific structure of the umbrella handle can be found in the relevant description of Embodiment 1, and will not be repeated here.

[0037] In this embodiment, the second movable connecting ring 710 is located below the air supply assembly 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 second movable connecting ring 710 drives the second umbrella rib 700 to rise and rotate, it cannot rise further once it reaches contact with the bottom surface of the first connecting pipe 3132. This prevents the second movable connecting ring 710 from impacting the air supply assembly 300 and also avoids the problem of the first umbrella rib 600 bending away from the second umbrella rib 700 due to excessive rising distance of the second movable connecting ring 710. The lower part of the second movable connecting ring 710 is also provided with a sleeve. A guide hole corresponding to the sleeve is opened on the lower rod 110 of the hollow rod 100, and a pressing piece is inserted into this guide hole. The lower part of the pressing piece is elastically connected to the lower rod 110. During the use of the parasol, pushing the second movable connecting ring 710 causes the second umbrella rib 700 to rise. Simultaneously, through the hinged connections between the second umbrella rib 700 and the first umbrella rib 600, and between the first umbrella rib 600 and the first movable connecting ring 610, both the first umbrella rib 600 and the second umbrella rib 700 swing together to open the umbrella fabric 800. When the sleeve slides to contact the pressing plate, the inner wall of the sleeve presses against the pressing plate, causing the pressing plate to retract into the guide hole, so that the sleeve can continue to rise with the second movable connecting ring 710. When the sleeve rises to leave the pressing plate, the constraint of the sleeve on the pressing plate is released, and the pressing plate rebounds and abuts against the lower end face of the sleeve, thereby achieving the positioning of the sleeve, the second movable connecting ring 710, the first umbrella rib 600, and the second umbrella rib 700, preventing the parasol from closing on its own under external impact.

[0038] In another embodiment, a bayonet is formed on the lower rod 110, and a strip-shaped hole is formed 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 member 730 is provided between the two lugs. The pressing member 730 is pivotally connected to the two lugs and elastically connected to the outer wall of the sleeve 720. The inner side of the pressing member 730 is provided with a locking block corresponding to the bayonet. When the sleeve 720 rises to the same height as the locking block and the bayonet, the locking block is inserted into the bayonet through the strip-shaped hole to achieve mutual constraint on the lower rod 110 and the sleeve 720. When the upper part of the pressing member 730 is pressed, the locking block is lifted and leaves the bayonet, releasing the constraint of the lower rod 110 on the sleeve 720, so that the sleeve 720 can slide down and the parasol can be closed. Of course, in actual design, the limiting structure between the sleeve 720 and the lower rod 110 can also be used for other umbrella handle positioning structures on the market, which will not be elaborated here.

[0039] The aforementioned parasol has an air supply assembly 300 consisting of a shell 310, a fan 320, and an air guide structure 330 fixed on the hollow pole 100. A battery 400 is installed in the handle 200 to power the fan 320. The fan 320 can be started by pressing the button 510 on the handle 200 and air is supplied to the user in the space under the umbrella, thereby improving the user's discomfort when holding the umbrella in hot weather. The fan 320 is housed in the shell 310 and the air is guided by the air guide structure 330 from the lower side wall of the shell 310 to supply air to the user from the side of the umbrella handle. This avoids the safety problem caused by the user's hair or other objects getting tangled in the fan blades 323 due to the exposed fan blades 323, thus improving the safety of the parasol's air supply assembly 300.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
