It oppresses and liquid is oriented to specific centrifugation track, to naturally smoothly to the surrounding sprinkling for centrifuging throwing disc.
When centrifuging sprinkling under throwing disc drive due to liquid, liquid can fly out outward under the action of the centrifugal force.At this point, centrifugation
Liquid in throwing disc can have the trend being constantly displaced outwardly because of centrifugation force effect.And since centrifugation throwing disc is usually side
The structure that edge tilts down, so liquid is easier to accumulate in the top position of diversion trench 11, that is, close to the one of upper throwing disc 1
Side.Thus, it allows diversion trench 11 and upper throwing disc 1 to connect, the gear of diversion trench 11 can be allowed to be easier to the outside at accumulation in liquid, avoid medicine
Liquid flies out and influences the water conservancy diversion efficiency of diversion trench 11 from the gap between 1 lower surface of diversion trench 11 and upper throwing disc, to improve
Improve the atomizing effect of centrifugation throwing disc.
As an alternative embodiment, in order to allow liquid to be passed through inside centrifugation throwing disc, the top center portion of upper throwing disc 1
Position is provided with the inlet 12 being connected to channel.In this way, liquid can be passed through from the inlet 12 at 1 top of upper throwing disc, and downwards
In channel in inflow between throwing disc 1 and lower throwing disc 2, then sprinkling is thrown away outward by centrifuging the rotation of throwing disc.Inlet 12
Positioned at the centre of upper throwing disc 1, thus liquid can enter the central area of centrifugation throwing disc, then the fringe region to centrifugation throwing disc
Movement is thrown away.
And in order to provide centrifugal flow guiding effect to liquid, diversion trench 11 can be there are many different specific implementation modes.With
It is lower the structure of diversion trench 11 to be described in more detail.
As the optional structure of one of which, diversion trench 11 can be leaned on by being extended to close to the side at the center of upper throwing disc 1
The side at the edge of nearly upper throwing disc 1.In this way, diversion trench 11 forms the side for extending to upper throwing disc 1 by the central area of upper throwing disc 1

The direction of diversion trench 11 gradually to movement on the outside of centrifugation throwing disc, until being thrown away outward from the fringe region of upper throwing disc 1 in mist.
Wherein, diversion trench 11 can have a variety of different development lengths in upper throwing disc 1.For example, the one of diversion trench 11
End can be located at the center of upper throwing disc 1, and the other end extends to the edge of throwing disc 1；Can also be diversion trench 11 by with
There is the position of certain distance to set out at the center of upper throwing disc 1, and extend to the position for having certain distance with the edge of upper throwing disc 1
Deng.Diversion trench 11 is arranged to different development lengths in upper throwing disc 1 in this way, can form different drop atomizing effects accordingly
Or different spraying ranges, to be adapted to different sprinkling and use occasion.
And in order to improve dispersion and guide effect of the diversion trench 11 to liquid, liquid can be disperseed and uniformly from centrifugation
The circumferential all directions of throwing disc spray out, and optionally, diversion trench 11 can be multiple, and 11 or more throwing disc 1 of multiple diversion trenches
The center of circle centered on be arranged radially.
In this way, the inlet of upper throwing disc 1 can be surrounded at the diversion trench 11 of radial arrangement around 1 center of circle of upper throwing disc
Wherein.It, will be to centrifugal drying disk center under the centrifugal action of centrifugation throwing disc after liquid enters upper throwing disc 1 by inlet 12
Moving around for position is scattered, and is respectively enterd in multiple diversion trenches 11 on the outside of centrifugation throwing disc.At this point, radially arranging
The high speed rotation of centrifugation throwing disc can be coordinated by being listed in multiple diversion trenches 11 of inlet periphery, allow liquid prolonging along diversion trench 11
It stretches direction movement and spills from the circumferential edge of centrifugation throwing disc in mist.
Wherein, diversion trench 11 can be a variety of different composed structures.Fig. 4 be the utility model embodiment one provide from
A kind of structural schematic diagram of diversion trench in heart throwing disc.As shown in figure 4, as a kind of common structure type, each diversion trench 11
May each comprise the deflector 111 of at least two spaced settings, deflector 111 is arranged in the bottom surface of upper throwing disc 1, and with above get rid of
Disk 1 collectively forms the cell wall of diversion trench 11.At this point, due to having interval between different deflectors, thus can be at least two
It is formed for liquid medicine flow and the space thrown away between deflector.And the side and bottom surface in the space respectively by deflector 111 with
And the bottom surface of upper throwing disc 1 is surrounded.The bottom surface of deflector 111 and upper throwing disc 1 can form water conservancy diversion collectively as cell wall in this way
Slot 11.
When diversion trench 11 is formed by the deflector 111 of at least two spaced settings, the more of diversion trench 11 are formed

Outside, can also allow between the deflector 111 of composition diversion trench 11 be in front and back variation spacing, such as allow diversion trench 11 along liquid stream side
To in pre-large post-small or pre-small post-large shape, speed is thrown away to change liquid.
Fig. 5 is the structural schematic diagram of another diversion trench in the centrifugation throwing disc that the utility model embodiment one provides.Such as Fig. 5
Shown, in another guide trough structure, diversion trench 11 can also be the groove opened up out on the bottom surface of upper throwing disc 1.This
When, the opening of groove is flushed with the bottom surface of upper throwing disc 1, and groove is integrally located inside the bottom surface of throwing disc 1.In this way, upper throwing disc 1
Bottom surface can between lower throwing disc 2 mutual assembly connection, to make lower throwing disc 2 cover the opening in groove, and groove is sealed
It shuts and, constitute diversion trench 11.
In addition, the diversion trench 11 of upper throwing disc 1 can also use the common groove structure of other those skilled in the art and shape
Formula, details are not described herein again.
And since liquid is thrown out of in the inner passage of centrifugation throwing disc by centrifugal force, so correspondingly, diversion trench 11
It may generally be of throwing away the more identical shape in track with liquid.Fig. 6 is the centrifugal drying that the utility model embodiment one provides
The channel shape schematic diagram of upper throwing disc in disk.As shown in fig. 6, for example, diversion trench 11 can be arc groove.Fairshaped arc
Slot can play good centrifugation guiding role for liquid, meanwhile, guide groove 11 can also pass through when providing guiding for liquid
The camber line of cell wall and reduce the head-on crash between liquid and the cell wall of diversion trench 11, allow liquid more to smoothly pass over diversion trench
11 inside ensures that liquid throws away speed when sprinkling is thrown away with enough to reduce the velocity attenuation of liquid to the greatest extent.This
Outside, the diversion trench 11 of arc can also be such that liquid has preferable to throw away direction and throw away angle, it is ensured that liquid has normal
Spraying range.
When diversion trench 11 is arc groove, direction and speed, diversion trench 11 are thrown away to further improve throwing away for liquid
Camber line can be Archimedes's camber line.Wherein, Archimedes's camber line is properly termed as Archimedes spiral or constant velocity spiral again,
While specifically illustrating a point and at the uniform velocity leave a fixed point, and with fixed angular speed is rotated around the fixed point and is generated
Track.And in the centrifugation throwing disc of the present embodiment, since centrifugation throwing disc such as is in when rotated at the rates rotation, and liquid is conveyed into
The flow velocity for centrifuging throwing disc is approximately constant again, so when centrifuging throwing disc by centrifugal force sprinkling liquid, the drop of liquid is same
Sample is similar to leave the center of centrifugation throwing disc with constant rate of speed, and simultaneously under the drive of centrifugation throwing disc, carries out with fixed angles speed
The rotation around centrifugal drying disk center is spent, i.e. the same approximation of movement locus of liquid defers to Archimedes's camber line.In this way, diversion trench 11
Camber line when being Archimedes's camber line, the arc shape of diversion trench 11 being capable of drop of the preferable and liquid when being thrown away by centrifugation
Movement locus matches, thus by liquid naturally smoothly by being exported in centrifugation throwing disc, and the surrounding to centrifugation throwing disc is spilt, make medicine
Liquid has preferable spray effect.
And throwing disc is centrifuged when spraying misty liquid around, and in order to allow liquid that can smoothly settle, entire centrifugal drying
Disk is in the shape that has a down dip.At this point, edge of the central part of centrifugation throwing disc higher than centrifugation throwing disc.Due to the medicine in centrifugation throwing disc
Liquid usually throws away sprinkling from the center of centrifugation throwing disc to the edge of centrifugation throwing disc, thus when the central part of centrifugation throwing disc is high
In centrifuge throwing disc edge when, centrifuge throwing disc in channel also can by centrifugal drying disk center to centrifugal drying plate edge it is gradual under
Drop, and the liquid in channel can also be moved down in the case where channel limits.Thus liquid, can be in centrifugation throwing disc when centrifuging sprinkling
When gradually moving under shape limitation, and being thrown away from the marginal portion of centrifugation throwing disc downward, can also have downward velocity component.Cause
And even if liquid is dispersed into move downward and realize the sedimentation of liquid if misty drop under effect of inertia, to
Liquid is allowed to trickle down the region sprayed to needs, the case where being scattered on a large scale in air without liquid.
When entirely centrifuging the central part of throwing disc higher than the edge for centrifuging throwing disc, correspondingly, upper throwing disc 1 is got rid of under
The shape that central part is higher than edge equally can be also presented in disk 2, in this way, the upper table of the lower surface of upper throwing disc 1 and lower throwing disc 2
The channel being gradually reduced from inside to outside is may make up between face, allows in channel the liquid flowed through to have and downward throws away speed.
Wherein, upper throwing disc 1 and lower throwing disc 2 can equally have a variety of different concrete shapes and structure.For example, upper throwing disc
1 and the upper and lower surface of lower throwing disc 2 can be in the same or similar shape that has a down dip with entire centrifugation throwing disc, at this point, the above throwing disc 1
For, the lower surface and upper surface of upper throwing disc 1 can be that central part is higher, and the lower shape in edge, and on get rid of
Be generally near between the upper and lower surface of disk 1 it is parallel or have similar tilt angled down.Likewise, lower throwing disc 2 can also have
Have with shape similar in upper throwing disc 1, details are not described herein again.
And as another embodiment, the lower surface of the only upper throwing disc 1 due to constituting the channel for throwing away liquid
With the upper surface of lower throwing disc 2, thus other positions of upper throwing disc 1 and lower throwing disc 2 can be other shape.For example, lower throwing disc 2
Lower surface can be in the horizontal direction or level of approximation setting plane, in this way, centrifugation throwing disc bottom shape it is more regular,
Shape is more beautiful.
Further, there is preferable effect of settling and more properly in order to ensure to centrifuge the misty liquid droplets that are sprayed of throwing disc
Coverage area, optionally, centrifuge the central part of throwing disc to the line and horizontal plane between the edge of centrifugation throwing disc it
Between can have angle a, and the range of angle a is usually between 10 °~40 °.
Wherein, it since the height of the central part of centrifugation throwing disc is higher than the height of edge, thus centrifuges in throwing disc
It is direction obliquely to entreat position to the line between the edge of centrifugation throwing disc.At this point, the angle a between line and horizontal plane
It is bigger, then throwing disc is centrifuged when throwing away liquid, and the downward velocity component of drop is also more.In general, in order to allow drop can
It smoothly settles, and ensures that centrifuging the drop that throwing disc is sprayed, there is sufficiently large coverage area, the range of angle a to be maintained at
Between 10 ° to 40 °, and angle is bigger, and drop downward velocity is higher, and drop is also easier to be settled.
In general, in order to allow centrifugation throwing disc that there is larger spraying range, the central part of throwing disc is centrifuged to centrifuging throwing disc
Edge between line and horizontal plane between angle a be typically about 10 °.At this point, centrifuging throwing disc institute when rotated
The liquid drop thrown away can form larger coverage area, and drop has good effect of settling.
In addition, realizing reliable connection to allow between diversion trench 11 and upper throwing disc 1, diversion trench 11 and upper throwing disc 1 are avoided
Between generate and allow the gap of liquid leakage, can be an integral molding structure between diversion trench 11 and upper throwing disc 1.Using integrated molding
The upper throwing disc 1 that structure is formed, there is no gap or notches between the root of diversion trench 11 and the lower surface of upper throwing disc 1, so
Liquid will not be leaked to from the root of diversion trench 11 outside diversion trench 11, and centrifugation throwing disc is higher to the spraying efficiency of liquid.
Specifically, when being an integral molding structure between diversion trench 11 and upper throwing disc 1, integrally formed concrete mode can root
Different variations are generated according to different materials used by centrifugation throwing disc.For example, when the upper throwing disc 1 in centrifugation throwing disc uses aluminium alloy
When equal metal materials are made, diversion trench 11 can be formed in by the modes such as metal cutting process or forging and stamping, molding and be got rid of
In the one side of the lower throwing disc of the direction of disk 12；And when upper throwing disc 1 is plastic part or resin piece, entire upper throwing disc 1 and diversion trench
11 can take injection molding manner to be formed, and constitute a unified entirety.
In addition it is also possible to using 3D printing rapid shaping technique or other well-known to those skilled in the art one
Body formed mode forms the integrated formed structure of diversion trench and upper throwing disc, is repeated no more in the present embodiment.
In the present embodiment, centrifugation throwing disc for rotating and spraying liquid, centrifugation throwing disc include the upper throwing disc being arranged concentrically and
