Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Fig. 1 to Fig. 3 shows a kind of filter screen embodiment provided by the invention.
The filter screen includes installation axle 5 and four rotation Dropbox being set in installation axle 5, and installation axle 5 is prolongs along axis
The shaft-like structure stretched, four rotation Dropbox include the first rotation Dropbox along the first direction setting for being parallel to 5 axis of installation axle
1, the second rotation Dropbox 2, third rotation Dropbox 3 and the 4th rotation Dropbox 4.First rotation Dropbox 1, second rotates Dropbox 2, third
Rotation Dropbox 3 and the 4th rotation 4 diameter of Dropbox are sequentially increased.
Four rotation Dropbox include the outer ring structure for being arranged the mounting disc 8 for being installed on installation axle 5 and being fitted around the setting of disk 8
6.The rotation twine 7 of arc-shaped Filamentous arrangement planar is provided between outer ring structure 6 and mounting disc 8.Rotate twine 7
Longitudinal section and/or cross section are in that arcuation is arcuate structure.Cambered design intercepts the grease of peripheral direction, improves and intercepts effect
Rate.The width for rotating twine 7 is preferably 0.5mm-1.2mm.It is provided with oil guiding hole on outer ring structure 6, for will intercept, assemble
Grease be thrown in the oil ring of surrounding.
Two neighboring rotation Dropbox meets following relationship:
Wherein, R1 is the radius of smaller rotation Dropbox, and w is the angular speed of installation axle 5, and n is the revolving speed of installation axle 5, w=
2* π * n.Grease is declined by gravity after the decoupling, and H is the spacing between two neighboring rotation Dropbox, can the time required to decline H
With formula H=1/2gt2It is calculated.A is margin parameter, preferably 5-10mm.
By analysis it is found that the grease in smaller rotation Dropbox can radially be thrown to adjacent rotation Dropbox maximum radius
Square be R12+ (w*R1*t)2.R2 is the radius of adjacent larger rotation Dropbox, and R2 should be not less than the oil in smaller rotation Dropbox
The maximum radius that rouge can be thrown to gets rid of the grease come in order to all accept smaller rotation Dropbox, needs to increase by 1 parameter surplus,
I.e.
The application is by being arranged multiple rotation Dropbox increased step by step, in rotary course, falls off from smaller rotation Dropbox
And the grease for not being thrown to oil ring is accepted by adjacent larger rotation Dropbox, is continued to drive grease rotation, is made grease by from level to level
The undertaking of rotation Dropbox is finally smoothly thrown in oil ring, is solved the problems, such as that grease is secondary and is entered air duct, can effectively protect centrifugation
The kernel components such as fan blade；Moreover, the rotation Dropbox that multilayer increases step by step, air quantity is big, and noise is small.
The setting of diameter minimum rotates Dropbox in top, also known as top layer in multiple rotation Dropbox, remaining Dropbox is lower layer
Rotate Dropbox.In the present embodiment, the first rotation Dropbox 1 is that top layer rotates Dropbox, and the second rotation Dropbox 2, third rotate 3 and of Dropbox
4th rotation Dropbox 4 is referred to as lower layer's rotation Dropbox.
The mounting disc 8 of lower layer's rotation Dropbox includes the spider with mounting hole 9 and the installation being sheathed on the outside of spider
Outer ring 10 is installed and is provided with rotation twine 7 between outer ring 10 and outer ring structure 6, support bar 11 is provided between spider, and
The support bar 11 of each lower layer's rotation Dropbox is aligned.So set, replacing filter screen with support bar 11, being only arranged several can be played
Supporting role, and the alignment of support bar 11 of each lower layer rotation Dropbox is not staggered, and can reduce each layer rotation Dropbox overlapping bit
The windage set reduces noise.Preferably, the diameter for installing outer ring 10 should be no more than the outer ring structure of adjacent lesser rotation Dropbox
6 diameter.
There is the mounting hole 9 cooperated with installation step 12 in mounting disc 8.Be provided in installation axle 5 with mounting hole 9 cooperate with
The installation step 12 of fixed corresponding rotation Dropbox.For the ease of be installed on assembly, four installation steps 12 along first direction successively
Increase, the mounting hole 9 of four rotation Dropbox is also sequentially increased, and size should be enough across lesser installation step 12 before.Rotation
Dropbox is fixed with installation axle 5 using the mode well known to those skilled in the art such as riveting, screw, welding, viscose glue.
The present embodiment introduces the working principle of the application so that four rotate Dropbox as an example, it should be apparent that, it is revolved in filter screen
The number for turning Dropbox does not limit to four, can be designed as three, five etc. according to the actual situation.
As another embodiment, structure identical with top layer rotation Dropbox can be used in all rotation Dropbox, i.e., not
Support bar 11 is set.
As another embodiment, each rotation Dropbox clipping room is away from different spacing are set as, along first direction spacing
It gradually decreases；It is designed in this way, the diameter of the first rotation Dropbox 1 is small, and centrifugal force is small, and the distance that big some greases are thrown away is arranged in spacing
It can be more greatly, that is, the rotation Dropbox of small diameter may make to throw away distance with bigger.
Invention also provides range hood embodiment, which includes the filter screen in above-described embodiment.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
