Justice.
In the description of the present invention, it should be understood that term " first ", " second " etc. are used for description purposes only,
It is not understood to indicate or imply relative importance.In addition, in the description of the present invention, unless otherwise indicated, it is " more
It is a " it is meant that two or more.
As shown in Figure 1, be a kind of structure of existing fan, including pedestal 5 ', for being integrally supported to fan, with
Guarantee the stability in fan use process.Support rod 4 ' is provided on pedestal 5 ', the end of support rod 4 ' is provided with adjustment portion
6 ', adjustment portion 6 ' is connected with the head of fan, is able to drive motor 1 ' and fan guard 3 ' is run together, large range of to carry out
Air-supply.Fan further includes motor 1 ', and the motor shaft 2 ' of motor 1 ' is connected with the impeller of fan, and motor shaft 2 ' rotates impeller and turns
It is dynamic.The outside mask of impeller is equipped with fan guard 3 ', is damaged with preventing impeller from quickly rotating to user.But due to motor 1 '
Horizontal positioned, motor shaft 2 ' is horizontally extending, and the gravity of fan guard 3 ' acts on the end of motor shaft 2 ' in the vertical direction,
To cause the end stress of motor shaft 2 ' larger, in 2 ' rotation process of motor shaft, as the revolving speed of motor shaft 2 ' is higher, wind
The entire head stress of fan is more uneven, and fan guard 3 ' is easy to form resonance effects with motor shaft 2 ', to generate biggish make an uproar
Sound influences the usage experience of user.
To solve the above-mentioned problems, this application provides a kind of fans, can be effectively reduced making an uproar in fan operational process
Sound greatly promotes the usage experience of user.As shown in Fig. 2, the fan in the application includes head 1 and is connected with head 1
Driving device 2, the driving device 2 include ontology 21 and drive shaft 22, and the head 1 includes fan guard 11, pass through the wind
The plumb line of the center of gravity of fan cover 11 and the drive shaft 22 are coaxially disposed.Preferably, driving device 2 includes motor, and ontology 21 wraps
Motor body 211 is included, drive shaft 22 includes the motor shaft 221 being connected with motor body 211.221 free end of motor shaft and fan
Flabellum be connected, to drive flabellum to rotate, thus certain driving air-flow flowing blow.Due to by the vertical of the center of gravity of fan guard 11
Line and motor shaft 221 are coaxially disposed, i.e., motor is vertically arranged, vertical direction be arranged in fan guard 11 surface or just under
Side, therefore, the gravity of fan guard 11 no longer perpendicular acting enables to motor and wind in the end of the free end of motor shaft 221
Fan cover 11 forms dynamic balancing after combining, and in 221 rotation process of motor shaft, fan guard 11 is not easy to produce with motor shaft 221
Raw resonance, to effectively reduce the noise in 221 rotation process of motor shaft.
Further, the motor shaft 221 is upwardly extended in vertical direction from the motor body 211, i.e. motor body
211 are arranged below, and motor shaft 221 upwardly extends in the vertical direction.It is, of course, understood that can also be by motor body
211 are vertically arranged, and motor shaft 221 is extended downwardly in vertical direction.The head 1 of fan further includes flabellum, drive shaft 22 and institute
It states flabellum to be fixedly connected, to drive flabellum rotation to blow.The fixed form of flabellum and motor shaft 221 can pass through fastener
It is attached, can also be fixed together the two by the modes such as being such as clamped.
Further, fan guard 11 includes dish type cover 111, the axis of the dish type cover 111 and the drive shaft
22 coaxial arrangements, the dish type cover 111 are set to the top of the flabellum in vertical direction.So that dish type cover 111
Entire weight act on the motor shaft 221 being vertically arranged.Since the rigidity of motor shaft 221 is larger, and under normal conditions
Dish type cover 111 mostly uses plastic material to be made greatly, and therefore, motor shaft 221 will not act on it because of the weight of fan guard 11
Above generate damage.But the mode of action between the gravity due to fan guard 11 and motor shaft 221 becomes coaxial from being mutually perpendicular to
Setting, in 221 rotation process of motor shaft, fan guard 11 and motor shaft 221 are not likely to produce resonance, reduce vibration noise.
Further, the fan includes support construction 3, and the support construction 3 includes pedestal 31 and support rod 32,
The lower end of the support rod 32 is connected with the pedestal 31, and the upper end of the support rod 32 is provided with accommodating chamber 321, described
Motor is set in the accommodating chamber 321.Fan in compared with the prior art, reduces adjustment portion, not only reduces zero
The quantity of part reduces the installation steps in installation assembling process.Simultaneously as adjustment portion is no longer arranged, without considering motor
With the assembly technology between fan guard 11, reduces an assembly technology step, reduce assembly cost and material cost, into one
Step promotes economic benefit.
In order to expand the blowing range of fan, the fan further includes air-supply adjustment structure 4, the air-supply adjustment structure 4
For changing the air supply direction of the fan, to realize 360 ° of air-supply effects.In a specific embodiment, the air-supply is adjusted
Section structure 4 includes the pipe fitting 41 that can be bent or bend being arranged on the flabellum, by the bending for changing the pipe fitting 41
Or overbending direction, adjust the air supply direction of the fan.Preferably, pipe fitting 41 is fabricated from a flexible material, to facilitate user needing
When being adjusted to air supply direction, pipe fitting 41 is bent or is bent according to air-supply demand.It is, of course, understood that
The plate being fabricated from a flexible material can also be set by pipe fitting 41, to obtain preferably air-supply deflecting effect.Furthermore it is also possible to
Plate is arranged on fan guard 11, is respectively set on fan guard 11 and plate with the use of shackle member, passes through shackle member
Cooperation, enables the setting position of plate to change, to change the air supply direction of fan, being provided on the position of plate does not have gas
Stream passes through, and being not provided on the position of plate has air-flow to pass through, and blows to user.
In another specific embodiment, the air-supply adjustment structure 4 include setting the drive shaft 22 with it is described
Gear drive between fan guard 11, the gear drive include the driving gear being connected with the drive shaft 22 and
The driven gear being connected with the fan guard 11, motor shaft 221 rotate while driving flabellum and driving gear to rotate, the active
Gear rotation drives the driven gear rotation, and then the fan guard 11 is driven to swing in transverse direction, wider
Inside blow.The driving gear and the driven gear are bevel gear, the axis of the driving gear with it is described driven
The axis of gear is mutually perpendicular to.It is, of course, understood that driven gear can be set it is multiple, and by be arranged it is multiple
Driven gear may be implemented fan guard 11 and blow in multiple directions, to improve air-supply flexibility and reliability.
The motor of fan in the application is arranged in vertical direction, not only solves that noise existing for existing fan is big to ask
Topic, is also greatly reduced the production cost of fan.By setting air-supply adjustment structure, the fan in the application can be realized multidimensional
The air-supply for spending multi-angle, improves the usage comfort and satisfaction of user.
Those skilled in the art will readily recognize that above-mentioned each preferred embodiment can be free under the premise of not conflicting
Ground combination, superposition.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for art technology
