A connection post is fixed on a spindle of the motor of the fan, the section of the connection post forms irregular shape, and the connection post can be used for the sheathing combination of the sleeve barrel parts of at least more than two blade bodies of the connection post; a spiral blade is extended from one side of the sleeve barrel part, and when the spindle of the motor rotates, each blade body also rotates; thus, the blades on the blade bodies shift air, and furthermore, spiral vortex wind of 360 DEG is generated.

Description

Can 360 the fan of degree rotation

The utility model relate to a kind of can 360 the fan of degree rotation, refer to especially a kind ofly make simple and when implementing, can form the helical winds of 360 degree, and make the fan blade that all can blow to wind from all directions, belong to individual and household goods field.

General traditional vertical fan, mainly be to install a swing arm in the rear end of motor seat, and control this swing arm by a small motor, make fan form brushing of move left and right, brush area with increase, but it is this in the wiggly mode of oscillating arm mechanisms control fan, owing to be subject to the restriction that swing arm itself has mechanism's limit, so maximum swing that only can reach 180 degree, the shortcoming that people at the fan rear can't brush has just appearred, so someone is in order to improve the shortcoming of this kind conventional fan, just develop a kind of can 360 the electric fan of degree rotation, and be a typical example as the novel patent case of No. the 219118th, Taiwan Announcement Number " can the rotating electric fan of 360 degree " wherein, and this kind electric fan mainly is to be provided with an outrigger, and in this outrigger, be pivoted with a skeleton again, be provided with dynamic components such as motor gear in the skeleton, and on dynamic component the installing one flabellum, and this electric fan is when rotating, thereby be that dynamic component is driven flabellum is rotated, and utilize gear to make skeleton in outrigger, form 360 degree rotations equally together with fan, reach the effect of can 360 each orientation of degree brushing with this.But still there are many shortcomings in this kind fan, now is analyzed as follows:

1. complex structure, the manufacture cost height: this ＂ can 360 the rotating electric fan ＂ of degree except motor and flabellum, also include numerous parts such as outrigger, skeleton, upper and lower axle bed, gear train, conductive hoop, insulating cylinder, elastic element, dynamic component, make manufacturing and assembling trouble with this, and cost is greatly improved.

2. wind direction only is formed on the plane, and can't form three-dimensional wind: when rotating owing to this kind flabellum, its wind direction is into straight blowing out, though so can form the rotation of 360 degree, but that is brushed pneumaticly only becomes the mode on plane to blow out, the top of fan can't be brushed equally, so this kind fan still has its deficiency.

The purpose of this utility model be to provide a kind of manufacturing and simple and convenient assembly, cost low can 360 degree rotations fan, and it is pneumatic to produce a kind of spiral helicine eddy current, makes from all directions and all can blow to wind.

The technical solution of the utility model is: be equiped with a motor on the fan, and protrude out a motor spindle in motor inside, the sheathed binding post that is fixed with on the motor spindle, the section that links post forms irregular shape, this attachment post can be conducted to less plural blade body and form sheathed with symmetrical manner, one side of this blade body is provided with a sleeve part, but the central authorities of this sleeve part form an engage sleeves and are located at the perforation that links post, and the opposite side of sleeve part, then extend and be parallel to the axial spiral blade of sleeve part, the axle of motor drives the attachment post rotation, and attachment post drives the rotation of helical fan blade, forms the eddy current wind that to all the winds brushes.

Advantage of the present utility model is:

1. simple in structure, low cost of manufacture: the utility model only utilizes a mould during fabrication, can produce the blade body for the different direction utilization, can reach the good efficacy that reduces parts and reduce cost.

2. can form three-dimensional wind: the utility model drives each blade body by motor spindle and rotates, and make the blade on the blade body stir air, and then it is pneumatic to produce a kind of spiral helicine eddy current, makes all can brush cool breeze around upper and lower.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
