Description
Technical field
The utility model is related to fan art, specifically a kind of tubular draught fan structure.
Background technology
Electric fan is one of common household electrical appliance of family, can play the role of air-supply cooling.Prior art electric fan by
Motor installs flabellum by output shaft, flabellum rotation is driven using motor to realize air blowing function, since flabellum itself has weight
Power, if wanting to do fan blade area greatly to obtain larger outlet air surface, flabellum more demanding to the material hardness of motor output shaft
It itself also requires to select light material as possible.Therefore prior art electric fan is asked there are outlet air surface by what own material was limited
Topic.
Utility model content the purpose of this utility model is to provide a kind of tubular draught fan structure, to solve existing skill
The problem of art fan is difficult to obtain larger outlet air surface.
In order to achieve the above object, technical solution is used by the utility model：
A kind of tubular draught fan structure, it is characterised in that：Including insulation outer barrel and concentrically axis is rotatably installed in insulation
Insulation inner cylinder in outer barrel, insulation inner cylinder inner wall are equipped with multiple tracks flabellum, and insulation two symmetrical side of inner tank theca is distinguished fixing sleeve and is equipped with
Conductive semi-ring, insulation two symmetrical side of outer tube inner wall are respectively equipped with brush, and the brush can be in electrical contact with conductive semi-ring, insulation
Inner tank theca corresponds to each conductive semi-ring centre position and has also been respectively embedded into electrode slice, and electrode slice one end is respectively fixedly connected in place
It puts on corresponding conductive semi-ring, the electrode slice other end is horizontal-extending respectively in axial direction to pass radially through insulation inner cylinder barrel respectively again
Afterwards, then along insulation inner cylinder inner wall interconnection is extended to, two symmetrical sides that the insulation outer tube inner wall avoids brush are respectively equipped with
Permanent magnet, two permanent magnetism ferromagnetism are different, and electrode slice is located at position between two permanent magnets.
A kind of tubular draught fan structure, it is characterised in that：Rolling is fixed in the nozzle of the insulation outer barrel both ends
Pearl bearing, the insulation inner cylinder both ends are rotatably installed in the ball bearing of corresponding end respectively.
A kind of tubular draught fan structure, it is characterised in that：It is described insulation inner cylinder inner wall be in totally equipped with multiple tracks
Spiral flabellum.
A kind of tubular draught fan structure, it is characterised in that：Two brushes are positive and negative with external dc power respectively
Pole connects.
A kind of tubular draught fan structure, it is characterised in that：The arc of each brush is more than two conductive half to length
The arc in gap is to length between ring.
The utility model is approximate with traditional DC motor structure, when brush is passed through direct current, passes through conductive semi-ring, electricity
Pole piece is formed into a loop, and having in circuit can rotate entire circuit in the presence of electric current under the effect of external permanent magnet magnetic, i.e., conductive
Semi-ring, electrode slice rotation, and then insulation inner cylinder unitary rotation can be driven, the helical-blade that insulation inner cylinder is designed when rotating by inner wall
Piece can be such that air enters from insulation inner cylinder one end and from insulation inner cylinder other end outlet air.
The utility model compared with prior art electric fan, due to need not traditional motor shaft support blade structure, because
This is not high to material requirements, you can obtains larger outlet air surface, improves the air-out effect of fan.

Specific embodiment
As shown in Figure 1 and Figure 2, a kind of tubular draught fan structure, including insulation outer barrel 1 and concentrically axis is rotatablely equipped with
The insulation inner cylinder 2 to insulate in outer barrel 1,2 inner wall of insulation inner cylinder are equipped with multiple tracks flabellum 3, and 2 outer wall of insulation inner cylinder, two symmetrical side is solid respectively
Surely conductive semi-ring 4 is set with, 1 inner wall of insulation outer barrel, two symmetrical side is respectively equipped with brush 5, and brush 5 can connect with conductive 4 electricity of semi-ring
It touches, 2 outer wall of insulation inner cylinder corresponds to each conductive 4 centre position of semi-ring and has also been respectively embedded into electrode slice 6,6 one end of electrode slice difference
It is fixedly connected on the corresponding conductive semi-ring 4 in position, 6 other end of electrode slice is horizontal-extending respectively in axial direction radially to be worn respectively again
After crossing 2 barrel of insulation inner cylinder, then edge insulation 2 inner wall of inner cylinder extends to interconnection, and insulation 1 inner wall of outer barrel avoids the two of brush 5
Symmetrical side is respectively equipped with permanent magnet 7, and two permanent magnets 7 are magnetic different, and electrode slice 6 is located at position between two permanent magnets 7.
Ball bearing 8 is fixed in insulation 1 both ends nozzle of outer barrel, 2 both ends of insulation inner cylinder are rotatably installed in corresponding end respectively
Ball bearing 8 in.
2 inner wall of inner cylinder that insulate is equipped with multiple tracks totally helical flabellum 3.
Two brushes 5 are connect respectively with the positive and negative electrode of external dc power.
The arc of each brush 5 to length be more than two conductive semi-rings 4 between gap arc to length.
