Abstract
The hollow fan comprises a stator, a rotor and fan blades, wherein the stator is arranged on the outer ring of the rotor, the rotor is a circle of circular ring, and the outer ring of the fan blades is fixed on the inner ring of the circular ring. When the fan is used, the rotor positioned in the inner ring rotates to drive the fan blades in the inner ring of the rotor to rotate, so that air flow is formed. In the structure, the rotor is designed into a circular ring shape, and the fan blades are directly fixed on the inner ring of the rotor, so that the fan has no rotating shaft, if strip-shaped objects enter the fan, the objects can enter the central position of the fan along the fan blades in the rotating process of the fan blades, and the central position of the fan has no rotating shaft, so that the strip-shaped objects can be blown away along the fan blades and cannot be wound.
Description
Technical Field
The present invention relates to a fan.
Background
The existing fan generally comprises a rotating shaft, wherein the central part of a fan blade is fixed on the rotating shaft, and the rotating shaft is an output shaft of a motor. The fan with the structure can be blocked if a strip-shaped article enters the fan. And cleaning is very inconvenient, so improvement is needed.
Disclosure of Invention
The invention provides a hollow fan aiming at the defects in the prior art, wherein the fan is not provided with a rotating shaft and cannot be wound.
In order to solve the technical problem, the invention is solved by the following technical scheme: the hollow fan comprises a stator, a rotor and fan blades, wherein the stator is arranged on the outer ring of the rotor, the rotor is a circle of circular ring, and the outer ring of the fan blades is fixed on the inner ring of the circular ring. When the fan is used, the rotor positioned in the inner ring rotates to drive the fan blades in the inner ring of the rotor to rotate, so that air flow is formed. In the structure, the rotor is designed into a circular ring shape, and the fan blades are directly fixed on the inner ring of the rotor, so that the fan has no rotating shaft, if strip-shaped objects enter the fan, the objects can enter the central position of the fan along the fan blades in the rotating process of the fan blades, and the central position has no rotating shaft, so that the strip-shaped objects can be blown away along the fan blades and cannot be wound.
In the above technical solution, preferably, the inner ring of the stator is provided with a ring of teeth, each of the teeth is wrapped by a wire, and the outer ring of the rotor of the teeth is provided with a magnetic ring.
In the above technical solution, preferably, end covers are arranged at two ends of the stator, the end covers are fixed at two ends of the stator, and the end covers are connected with the rotor through bearings.
Compared with the prior art, the invention has the beneficial effects that: in the structure, the rotor is designed into a circular ring shape, and the fan blades are directly fixed on the inner ring of the rotor, so that the fan has no rotating shaft, if strip-shaped objects enter the fan, the objects can enter the central position of the fan along the fan blades in the rotating process of the fan blades, and the central position has no rotating shaft, so that the strip-shaped objects can be blown away along the fan blades and cannot be wound.
Drawings
FIG. 1 is a schematic cross-sectional view of the present invention.
Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and the attached drawings.
As shown in fig. 1, the hollow fan comprises a stator 1, a rotor 2 and fan blades 3, wherein the stator 1 is arranged on the outer ring of the rotor 2, the rotor 2 is a circle of ring, and the outer ring of the fan blades 3 is fixed on the inner ring of the ring. A ring of teeth 11 is arranged on the inner ring of the stator 1, each tooth 11 is wrapped by a lead 12, and a magnetic ring 4 is arranged on the outer ring of the rotor of each tooth 11.
End covers 5 are arranged at two ends of the stator 1, the end covers 5 are fixed at two ends of the stator 1, and the end covers 5 are connected with the rotor 1 through bearings 6.
When the magnetic rotor is used, the power supply is switched on through the conducting wires on the teeth, a magnetic field can be generated, so that the magnetic poles corresponding to the magnetic ring yarn function on the inner ring are attracted, the rotor is driven to rotate, the fan blades of the inner ring are rotated, and air flow is formed. In the structure, the rotor is designed into a circular ring shape, and the fan blades are directly fixed on the inner ring of the rotor, so that the fan has no rotating shaft, if strip-shaped objects enter the fan, the objects can enter the central position of the fan along the fan blades in the rotating process of the fan blades, and the central position of the fan has no rotating shaft, so that the strip-shaped objects can be blown away along the fan blades and cannot be wound.
Claims (2)
