A fan, as shown in fig. 1-7, which comprises a hub 1 and a plurality of fan blades 2 arranged along the circumference of the hub 1; specifically, the hub 1 comprises a shell and a cover body detachably connected with the shell; the shell and the cover body are matched to form an accommodating cavity; the accommodating cavity accommodates a driving unit for driving the fan blade 2 to rotate. The driving unit comprises an output connecting shaft M arranged along the radial direction of the hub 1; and an output connecting shaft M of the driving unit is connected with one end of the fan blade 2. When the driving unit works, the fan blade 2 is driven to rotate around an output connecting shaft M of the driving unit. In this embodiment, the surface of the fan blade 2 is arc-shaped to effectively drive the airflow to flow. In this embodiment, the fan is an axial flow fan.
As a practical way, as shown in fig. 2-3, the driving unit comprises an adjusting motor 3, a first bevel gear 4, and a second bevel gear 5. Wherein, the output shaft of the adjusting motor 3 is arranged along the axial direction of the hub 1; the first bevel gear 4 is connected with an output shaft of the adjusting motor 3; the second bevel gear 5 is meshed with the first bevel gear 4; and the end surface of the second bevel gear 5 far away from the central shaft of the hub 1 is connected with the fan blade 2. In the above, the motion and power transmission between the two intersecting shafts are realized by the adjusting motor 3, the first bevel gear 4 and the second bevel gear 5. That is, the adjusting gear, the first bevel gear 4 and the second bevel gear 5 are engaged to convert the rotation of the output shaft of the adjusting motor 3 along the axial direction of the hub 1 into the rotation of the output connecting shaft M of the second bevel gear 5 along the radial direction of the hub 1. The central axis of the second bevel gear 5 is the output connecting shaft M of the driving unit, and is arranged along the radial direction of the hub 1. The axial space and the radial space of the accommodating cavity of the hub 1 are fully utilized by the arrangement, so that the accommodating cavity of the hub 1 accommodates a plurality of driving units, and the installation angles of a plurality of fan blades 2 are adjusted. It should be noted that, in this embodiment, the installation angle adjustments of the plurality of blades 2 are independent from each other, and they can be adjusted regularly at the same angle, and they can also be adjusted according to their respective adjustment rules, so that the plurality of blades 2 form different installation angle combination modes, thereby realizing diversified air supply.
During operation, the adjusting motor 3 works and drives the first bevel gear 4 to rotate, the first bevel gear 4 is meshed with the second bevel gear 5 so as to drive the second bevel gear 5 to rotate, and the second bevel gear 5 drives the fan blades 2 to rotate so as to adjust the rotation angle of the fan blades 2.
As a practical way, the large end face of the second bevel gear 5 is located on the side of the small end face away from the central axis of the hub 1; on one hand, the space of the accommodating cavity of the hub 1 is effectively utilized; on the other hand, the connecting area of the second bevel gear 5 and the fan blade 2 can be increased.
In this embodiment, the hub 1 has a through hole on the housing, and the second bevel gear 5 corresponds to the through hole. The end face of the second bevel gear 5 connected with the fan blade 2 and the side face of the hub 1 are on the same cylindrical surface. Above setting up, effectively ensured on the one hand that first bevel gear 4 drives fan blade 2 and rotates to make 1 side of wheel hub and second bevel gear 5's terminal surface have wholeness and unity, effectively ensured the smoothness nature that the air current flows.
As an implementable manner, as shown in fig. 5 to 6, the output connecting shaft M of the driving unit intersects with the front end portion of the fan blade 2. Namely, the straight line where the output connecting shaft M of the driving unit is located passes through the front end part of the fan blade 2. Because the output connecting shaft M of the driving unit is arranged along the radial direction of the hub 1, the fan blades 2 rotate to the positions a, b and c around the front end part of the fan blades under the driving of the driving unit so as to adjust the installation angle of the fan blades. And the installation angles of the fan blades 2 are adjusted to form various combinations.
As an implementable manner, as shown in fig. 7, the output connecting shaft M of the driving unit intersects with the middle of the fan blade 2. Namely, the straight line of the output connecting shaft M of the driving unit passes through the middle part of the fan blade 2. Because the output connecting shaft M of the driving unit is arranged along the radial direction of the hub 1, the fan blade 2 rotates to the positions a ', b ' and c ' around the front end part under the driving of the driving unit so as to adjust the installation angle. The output connecting shaft M of the driving unit is intersected with the middle part of the fan blade 2, so that the rotating radius of the fan blade 2 is small, and the occupied space of the fan blade 2 rotating for a circle is small. It should be noted that the relative position between the fan blade 2 and the output connecting shaft M is not limited to the above arrangement, and it is arranged as required.
As an implementable mode, one end of the fan blade 2 close to the second bevel gear 5 is provided with a taper shank; one end of the second bevel gear 5, which is far away from the central shaft of the hub 1, is provided with a mounting hole, and the taper shank is mounted in the mounting hole so as to realize the connection of the second bevel gear 5 and the fan blade 2. On one hand, the manufacture of the single fan blade 2 is realized, and the processing is simple and convenient; on the other hand, the fan blade 2 is detachably connected with the second bevel gear 5 through the taper shank, so that the damaged fan blade 2 can be replaced conveniently and timely.
In addition, the drive unit comprises an energy supply device for supplying energy to the control motor 3, which energy supply device is designed as a battery or as a solar generator or as a wind turbine generator. When the energy supply device is set as a wind wheel power generation device, the wind wheel power generation device generates electricity by rotating the fan blades 2 when the fan works and supplies the electricity to the adjusting motor 3, so that the adjusting motor 3 drives the fan blades 2 to rotate to adjust the installation angle.
In the above, the present embodiment provides a fan, which includes a hub 1 formed with an accommodating cavity, and a driving unit accommodated in the accommodating cavity; the driving unit comprises an output connecting shaft M arranged along the radial direction of the hub 1; an output connecting shaft M of the driving unit is connected with a fan blade 2; the fan blades 2 are arranged along the circumferential direction of the hub 1; when the driving unit works, the fan blade 2 is driven to rotate around an output connecting shaft M of the driving unit; in the embodiment, the position of the fan blade 2 is adjusted through the driving unit, so that the installation angle of the fan blade 2 is adjusted, and diversified air supply is realized.
