Description

Technical Field

[0001] This utility model belongs to the field of Roman umbrella technology and relates to a multi-fan structure for Roman umbrellas. Background Technology

[0002] Traditional Roman umbrellas only serve the functions of sunshade and lighting. When used in hot weather, they are usually equipped with handheld fans. For ease of use, some Roman umbrellas have fans attached to their frames, which can be turned on and off by switching the fan on and off after the umbrella is opened.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN203182183U] discloses a solar-powered fan umbrella. A solar fan blade is mounted on the handle, and a solar panel is mounted on the top surface of the umbrella. A small motor is installed on the side of the top of the handle inside the umbrella canopy. The solar panel and the small motor are connected via an electrical circuit. A bearing is fitted onto the handle below the small motor, allowing the bearing to rotate around the handle. A pulley is fitted onto the upper end of the bearing, and a fan blade is fitted onto the lower end of the bearing. The fan blade is made of several soft materials to facilitate retraction and extension. The length of the fan blade is such that it does not touch the umbrella ribs when fully extended. A power switch is located at the end of the handle and is electrically connected to the small motor and the solar panel.

[0004] The above structure has solar fan blades installed on the umbrella handle. When not in use, the blades need to be folded up. At this time, the blades are made of soft material and can be retracted to be close to the umbrella handle. However, when closing the umbrella, the umbrella ribs also need to be close to the umbrella handle to facilitate the storage of the entire umbrella frame. Therefore, the umbrella ribs are prone to contact with the blades, and the blades are prone to being squeezed, which in turn affects the storage of the umbrella frame and the storage of the blades. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a multi-fan structure for Roman umbrellas. The technical problem this invention aims to solve is: how to resolve the issue that existing fan structures affect umbrella frame storage.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A multi-fan structure for a Roman umbrella, the Roman umbrella including an umbrella frame, the umbrella frame including a lower umbrella disc and lower umbrella ribs uniformly hinged to the lower umbrella disc circumferentially, an illumination lamp holder disposed below the lower umbrella disc, characterized in that a connecting shaft is connected to the lower end of the lower umbrella disc, the illumination lamp holder is connected to the lower umbrella disc through the connecting shaft, the multi-fan structure including multiple small fan assemblies, the multiple small fan assemblies being sequentially arranged circumferentially on the top surface of the illumination lamp holder, each small fan assembly including a driving member and multiple fan blades hinged to the driving shaft of the driving member, the outer edge of the fan blades being located radially within the outer edge of the illumination lamp holder when the driving member is not running.

[0008] By connecting the lighting fixture and the lower umbrella tray via a connecting shaft, a distance is created between them. Multiple small fan assemblies are arranged circumferentially on the top surface of the lighting fixture. When the drive unit is activated, it rotates the fan blades on the corresponding small fan assemblies to generate airflow. When airflow is not needed, the drive unit stops rotating. At this time, the outer edge of the fan blades is radially located within the outer edge of the lighting fixture. This ensures that when stored, the fan blades are concealed between the lighting fixture and the lower umbrella tray, without protruding. Consequently, this does not affect the folding and storage of the lower umbrella ribs, ensuring convenient storage and preventing damage to the fan blades from other parts of the umbrella frame during storage, thus avoiding any impact on the subsequent use of the fan blades.

[0009] In the multi-fan structure of the Roman umbrella described above, the driving component is a drive motor, which is fixedly connected to the top surface of the lighting fixture. The drive shaft of the drive motor is arranged vertically upward, and a swing frame is fixedly connected to the drive shaft. The fan blades are hinged to the swing frame.

[0010] Since the drive shaft is set vertically upwards, the fan blades, which are fixed to the drive shaft via the swing bracket, are also set upwards. This avoids interference between the fan blades and the lighting fixture when the fan blades rotate, improving the convenience of storage and use, and also facilitating the installation of the entire small fan assembly.

[0011] In the multi-fan structure of the Roman umbrella described above, the swing frame includes two radially arranged support plates, and a hinge shaft corresponding to the fan blades is rotatably connected between the two support plates. The fan blades are sleeved on the hinge shaft.

[0012] This structure allows for some staggered space when the fan blades are stacked, making the storage of the fan blades more stable.

[0013] In the multi-fan structure of the Roman umbrella described above, there is a clearance space between the drive unit and the connecting shaft for the fan blades to pass through.

[0014] The space provided ensures that the fan blades do not interfere with the connecting shaft when rotating, thus guaranteeing the stability of the small fan assembly.

[0015] In the multi-fan structure of the Roman umbrella described above, there are three small fan assemblies, which are evenly distributed circumferentially on the top surface of the lighting fixture.

[0016] The use of three small fan components minimizes the weight of the Roman umbrella while still providing good ventilation.

[0017] Compared with existing technologies, the multi-fan structure of this Roman umbrella has the following advantages: when stored, the fan blades are hidden between the lighting base and the lower umbrella plate, without protruding, thus not affecting the storage and folding of the lower umbrella ribs, ensuring convenient storage, and also avoiding damage to the fan blades by other parts of the umbrella frame during storage, which would affect the subsequent use of the fan blades.

[0028] By connecting the lighting base 2 and the lower umbrella tray 11 via the connecting shaft 3, a distance is created between the lighting base 2 and the lower umbrella tray 11. Multiple small fan assemblies 4 are arranged circumferentially on the top surface of the lighting base 2. When the drive unit 41 is activated, it drives the fan blades 43 on the corresponding small fan assemblies 4 to rotate, thus achieving fanning. When fanning is not needed, the drive unit 41 stops rotating. At this time, the outer edge of the fan blades 43 is located radially within the outer edge of the lighting base 2. This ensures that when stored, the fan blades 43 are hidden between the lighting base 2 and the lower umbrella tray 11 and do not protrude. Consequently, they do not affect the storage and folding of the lower umbrella ribs 12, ensuring convenient storage and preventing other components of the umbrella frame 1 from damaging the fan blades 43 during storage, thus affecting the subsequent use of the fan blades 43.

[0029] like Figure 2-4 As shown, the driving component 41 is a drive motor, which is fixedly connected to the top surface of the lighting fixture 2. The drive shaft 42 of the drive motor is arranged vertically upward. A swing frame 44 is fixedly connected to the drive shaft 42. The aforementioned fan blades 43 are hinged on the swing frame 44. The swing frame 44 includes two radially arranged support plates 44a. A hinge shaft 44b corresponding to the fan blades 43 is rotatably connected between the two support plates 44a. The fan blades 43 are sleeved on the hinge shafts 44b.

[0030] like Figure 5 and Figure 6 As shown, there is a clearance space 5 between the drive component 41 and the connecting shaft 3, which allows the fan blades 43 to pass through. There are three small fan assemblies 4, which are evenly distributed circumferentially on the top surface of the lighting fixture 2.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
