(FIt is viscous+FBulletSum and FLiquidRelation) the bionical switch valve of joint effect switch.A kind of bionical automatic urinating described in the present embodiment
The step of when device is normally run is：
Step one：When without urine or during less urine, the pressure that elastic circle body 2 is subject to is smaller, now elastic circle body 2 is swollen
Swollen tacky state, good elasticity, which can make the inner ring of elastic circle body 2 press together, can not form fluid passage 11, that is, block
Liquid flows to passage.Now, the viscous force F between the elastic inner ring of circle body 2It is viscousIt is very big, the elastic contraction state screen resilience F of circle body 2BulletFor 0,
Extruding force F of the liquid to fluid passage 11LiquidVery little.Now, the inward force that fluid passage 11 is subject to is more than or equal to outside
Power, i.e. FIt is viscous+FBullet≥FLiquid, liquid flows to passage closing under this state.
Step 2：Bionical urination valve when being closed mode when bladder urine is more, now bladder pressure becomes big, applies
The pressure for flowing to passage to liquid can also become big.The now viscous force F between elastic circle body 2It is viscousIt is constant, the elastic contraction state of circle body 2
Screen resilience FBulletFor 0, extruding force F of the liquid to fluid passage 11LiquidBecoming larger.The dynamic equilibrium of three is changing.
Step 3：(the F when pressure reaches critical valueIt is viscous+FBullet=FLiquid), now elastic circle body 2 shrinks, fluid passage 11 dozens
Open, liquid flows to passage opening, urine outflow.Elastic circle body 2 is Yi Dan opened, the bonding force F of elastomeric materialIt is viscousJust it is not present
(FIt is viscous=0), the now outside extruding force (F of liquidLiquid) it is much larger than elastomeric material screen resilience (FBullet), now urine is quickly discharged, from
And realize the process of automatic urethral catheterization.
Step 4：When elasticity circle body 2 is unbonded after urine discharge is a certain amount of (when not closed), bladder pressure diminishes, from
And being applied to liquid and flowing to the pressure of passage can also diminish, elastic circle body 2 slowly shrinks resilience.Due to the elastic material ratio of circle body 2
Softer, deformation is small, and the remaining urine of emptying in the time of resilience can be shunk in this section.During this, the F of elastomeric materialIt is viscousFor
0, FBulletWith FLiquidAll taper into.
Step 5：When remaining urine is less or not, elastic circle body 2 springs back to initial bubble tacky state, again certainly
Dynamic closed liquid passage 11.Now FIt is viscousIt is very big, FIt is viscous+FBullet >=FLiquid, liquid flow to passage closing.

Inhale, the S poles of first magnet 13, the N poles of N poles and another the first magnet 13, S grades of interval magnetic.Two semi-circular shape
First magnet 13 is symmetrically set in the centre of gyration line both sides of elastic circle body 2.
There is the gravitation attracted each other between two the first magnets 13, stable magnetic can be formed around the axle center of elastic circle body 2
, the class annular magnet that both form.The magnetic of first magnet 13 is weaker, has faint attraction between two semi-circular magnets.
Liquid flows to passage not to be changed with embodiment 1, the equilibrium relation for the power that the switch that liquid flows to passage is subject to by elastic circle body 2
It is controlled.First magnet 13 is embedded in inside elastic circle body 2, and when elastic circle body 2 is deformed upon, the first magnet 13 can also be sent out
Raw deformation or corresponding displacement.
Permanent magnet magnetic size FMagneticIt is the relation between (L)：
FMagneticApplied in the present embodiment, being power between two symmetrical first magnets 13, L is two in the present embodiment
The distance between symmetrical first magnet 13, k, b are constant.As can be seen here, the index of magnetic force size and distance be in inverse ratio, when away from
During from becoming big, magnetic force can rapid drawdown；Distance becomes hour, and magnetic force also can become big suddenly.The present embodiment is using magnetic force and between
The principle of non-linear relation, to the nonlinear change of elastic circle body applying power when being changed using distance between asymmetric magnetic material,
Auxiliary is switched to fluid passage.
Elastic circle body 2 has two states：Expandable adhesive state and extruding contraction state.When being without urine or during less urine
Expandable adhesive state；It is compressive state during the more entrance urination process of urine.Force diagram is as shown in Figure 7.Fluid passage 11 by
Power include four parts：Two piece of first magnet 13 attracts each other the inside magnetic attraction F to be formedMagnetic；During elastic 2 compressive state of circle body
To the inside screen resilience F of swelling state resilienceBullet；Inside bonding force F under swelling state between elastic circle body 2It is viscous；And work as
Outside extruding force F of the liquid in fluid passage 11 to elastic circle body 2Liquid.By the liquid in fluid passage 11 be subject to
Interior power FMagnetic、FBullet、FIt is viscousSum and outside power FLiquidBetween equilibrium relation, control fluid passage 11 switch.
The step of when a kind of bionical automatic urinating device of the present embodiment is normally run is：
Step one：As shown in figure 5, when without urine or during less urine, the pressure that elastic circle body 2 is subject to is smaller, now bullet
Property circle body 2 be expandable adhesive state, good elasticity can press together sealing liquid passage 11, that is, block liquid flow direction logical
Road.There is the attraction magnetic force of interaction between symmetrical first magnet 13, due to distance between two pieces of symmetrical first magnets 13
Relatively near, suction is larger, can help the preferably closure of fluid passage 11.The inside screen resilience F of elastic circle body 2 nowBulletVery little,
Almost it can be ignored, it is F to have larger bonding force between elastic circle body 2It is viscous.In this state, two pieces symmetrical first
Magnetic attraction F between magnet 13Magnetic, bonding force F between elastic circle body 2It is viscous, the inside screen resilience F of elastic circle body 2BulletThree's sum
Inside effect to elastic circle body is more than outside extruding force F of the liquid required when liquid is discharged to fluid passage 11Liquid, i.e.,
FMagnetic+FBullet+FIt is viscous≥FLiquid。
Step 2：When bladder urine is more and when liquid flows to passage closing, now bladder pressure becomes big, is applied to liquid
The pressure of direction of flow passage can also become big, outside extruding force F of the liquid to elastic circle body 2LiquidAlso it can become big.In this state
Under, now FLiquidBecoming larger, and FMagnetic、FIt is viscous、FBulletThese inward force sizes are constant, the dynamic equilibrium of inside/outside active force by
Gradually change.
Step 3：As shown in fig. 6, when urinary urine bladder hydraulic coupling reaches critical value (FMagnetic+FBullet+FIt is viscous=FLiquid), elastic circle body 2 is received
Contracting, fluid passage 11 is opened, and liquid flows to passage opening.Now between two first magnets 13 apart from L farther out, symmetrical two first
Suction (F between magnet 13Magnetic) diminish, and liquid flows to passage once opening, the viscous force F between elastic circle body 2 is viscous to be not present,
Numerical value is 0, realizes the process of automatic urethral catheterization, and now urine is quickly discharged.In this state, two pieces of symmetrical first magnets 13
Between magnetic attraction (FMagnetic) diminish, viscous force (F between elastomeric materialIt is viscous) it is 0, the elastic compressive state screen resilience (F of circle body 2Bullet) become
Greatly, this three's sum is less than or equal to outside to elastic circle body (fluid passage 11) when liquid is discharged to the effect of fluid passage 11
Extruding force (FLiquid), i.e. FMagnetic+FBullet+FIt is viscous≤FLiquid。
Step 4：When fluid passage 11 is not turned off after urine discharge is a certain amount of, bladder pressure diminishes, so as to be applied to liquid
The pressure of body passage 11 can also diminish, and the pressure that elastic circle body 2 is subject to diminishes, and slowly shrinks resilience.Due to symmetrical two first magnetic
Magnetic force between body 13 and the non-linear relation of distance between the two, when distant between two the first magnets 13, magnetic force meeting
Very small, the deformation of elastic circle body 2 will be slow, and deformation time is long；When the distance between two first magnets 13 are close
When, magneticaction can become big suddenly, and the deformation of elastic circle body 2 more can be influenceed by magnetic material, accelerating liquid passage
11 closure.In addition, the elastic material of circle body 2 is softer, deformation is small, can empty residual urine in this section shrinks the time of resilience
Liquid.In this state, now FLiquidGradually diminish, FMagneticGradually big, F is becomeBulletTaper into, FIt is viscousIt is zero, the dynamic between three is put down
Weighing apparatus is gradually changing.
Step 5：When remaining urine is less or not, elastic circle body 2 springs back to initial bubble state (as shown in Figure 9),
Block fluid passage 11 automatically again.In this state, the magnetic attraction F between two pieces of symmetrical first magnets 13Magnetic, elasticity
The inside screen resilience F of materialBulletThe cohesive force F between circle interlude in elastic ring bodyIt is viscousTo the inside effect sum of elastic circle body
To the outside extruding force F of elastic circle body when being discharged more than liquidLiquid, i.e. FMagnetic+FBullet+FIt is viscous≥FLiquid。

In this state, because fluid passage 11 is opened, the bonding force between elastic circle body 2 is not present, FIt is viscousNumerical value is 0.To liquid
The inside active force of passage 11 is less than or equal to extruding force F outside to fluid passage 11 when liquid is dischargedLiquid, i.e. FOutside+FBullet+FIt is viscous≤
FLiquid。
Step 4：When a certain amount of and fluid passage 11 of urine discharge is not turned off, bladder pressure diminishes, so as to be applied to liquid
Flowing to the pressure of passage can also diminish, and fluid passage 11 slowly shrinks resilience.Meanwhile, spring 18 also increasingly relaxes.This
Under state, now FLiquid、FBullet、FOutsideAll diminish gradually, FIt is viscousFor 0, the dynamic equilibrium between three is gradually changing.
Step 5：When remaining urine is less or not, elastic circle body 2 springs back to original state (as shown in figure 13), then
Secondary automatic closed liquid passage 11.The directed force F inside to fluid passage 11 of spring 18Outside, the elastic screen resilience F of circle body 2Bullet, to bullet
The viscous force F of property circle body inner ringIt is viscousSum is more than liquid required when liquid is discharged to elastic circle body to the effect of elastic circle body inwardly
Extruding force FLiquid, i.e. FOutside+FBullet+FIt is viscous≥FLiquid。
