Mechanism 40 is saved, the second pumping mechanism 30 is connected to spray head 10 so that growth medical fluid is adjusted by concentration by concentration regulating mechanism 40
Enter mixing chamber 11 after mechanism 40, wherein：The pressure of the water that concentration regulating mechanism 40 is conveyed according to the first pumping mechanism is controlled
System enters the amount of the growth medical fluid of mixing chamber 11.Specifically, when the pressure for the water that the first pumping mechanism is conveyed increases, it is dense
The amount that degree regulating mechanism 40 makes to enter the growth medical fluid in mixing chamber 11 increases, when the pressure for the water that the first pumping mechanism is conveyed
When reduction, the amount that concentration regulating mechanism 40 makes to enter the growth medical fluid in mixing chamber 11 reduces.Such setting is advantageous in that：When
When the pressure for the water that first pumping mechanism is conveyed increases, illustrate that the amount of the water entered in mixing chamber 11 in the unit time increases,
Increase at this point, concentration regulating mechanism 40 synchronizes the amount of the growth medical fluid entered in mixing chamber 11 also, to make to grow medical fluid
It will not change because of increasing for water with concentration mixed by water, the melting concn for growing medical fluid and water is made to keep substantially constant；
When the pressure for the water that the first pumping mechanism is conveyed reduces, illustrate that the amount of the water entered in mixing chamber 11 in the unit time subtracts
It is few, at this point, concentration regulating mechanism 40 to enter the amount also synchronous reduction of the growth medical fluid in mixing chamber 11, to make to grow medicine
Liquid will not change with concentration mixed by water because of discharge reduction, so that the melting concn of growth medical fluid and water be made also to keep basic
It is constant.
Above-described embodiment, by that can make the concentration for growing medical fluid will not be because according to hydraulic pressure and using concentration regulating mechanism 40
The change of water and change.
In a preferred embodiment of the invention, as shown in Fig. 2, concentration regulating mechanism 40 is configured to such as flowering structure,
That is, the concentration regulating mechanism 40 includes：Keeping body 41, balance core, the first tributary 413, the second tributary 414, the first spring 43.Its
In, directed cavity is offered in keeping body 41, keeping body 41 is also provided with medical fluid and flows into runner 411 and medical fluid outflow runner 412,
Medical fluid flows into the first end of runner 411 for be connected to the second pumping mechanism 30, the second end of medical fluid inflow runner 411 penetrate through to
The first end of directed cavity, medical fluid outflow runner 412 is connected to mixing chamber 11, and the second end of medical fluid outflow runner 412 is penetrated through to mixed
Close chamber 11；Balance core is set in directed cavity so that directed cavity is divided into the first chamber 415 and the second chamber 416；First tributary 413 is from medicine
Liquid stream goes out runner 412 and is connected to the first chamber 415；Second tributary 414 is connected to the second chamber 416 from medical fluid outflow runner 412；First
Spring 43 is set in the second chamber 416 for pushing against balance core；First spring 43 is configured to the minimum type of coefficient of elasticity,
And compression degree is very big.Wherein, being provided with flow-passing surface on without the medical fluid outflow runner 412 before the second tributary 414 can be changed
Duct 56, the pressure for the water that the flow-passing surface in duct 56 is conveyed by the first pumping mechanism controls, when the pressure of water increases, control
The flow-passing surface in duct 56 increases, and when the pressure of water reduces, the flow-passing surface in control duct 56 reduces.
The course of work and advantage of the concentration regulating mechanism 40 of above structure are：
1, the pressure for the growth medical fluid that the concentration regulating mechanism 40 of above structure will not be conveyed by the second pumping mechanism 30
The amount for changing and entering growth medical fluid in mixing chamber 11 changes, and reason is：
The growth medical fluid that first pumping mechanism is conveyed is flowed into after runner 411 by medical fluid enters directed cavity and by being oriented to
The laggard liquid stream of being used as medicine of chamber goes out runner 412, after flowing out runner 412 into medical fluid, on the one hand, make the first chamber by the first tributary 413
415 have the growth medical fluids of certain pressure, and the growth medical fluid in the first chamber 415 is for pushing against balance core to generate the first effect
Power；On the other hand, medical fluid pressure reduction after duct 56 is throttled is grown, and a part makes the second chamber by second branch
There is the growth medical fluid of certain pressure, another part is directly entered mixing chamber 11, and the growth medical fluid in the second chamber 416 is used in 416
In pushing and pressing balance core to generate second active force opposite with the first effect forced direction, and simultaneously, the pushing and pressing of the first spring 43
Spool is to generate and the first force direction mutually third active force identical with the second force direction instead.When the first pumping machine
When the pressure for the growth medical fluid that structure is conveyed is in first pressure state, balance core slides into corresponding with the first equilibrium pressure states
First position, at this point, balance core stress balance, that is, the resultant force of the first active force, the second active force and third active force is
0, third active force is equal to the difference of the first active force and the second active force；When the pressure for the growth medical fluid that the first pumping mechanism is conveyed
Power changes, and such as increases, and balance core can slide into the second position, and the second position is higher than first position, at this point, balance core is again
Balance, that is to say, that the resultant force of the first active force, the second active force and third active force is 0 again, and third active force is equal to
The difference of first active force and the second active force.Since the first spring 43 is configured to the minimum type of coefficient of elasticity, and compress journey
Degree is very big, that is to say, that although balance core, at first position and the second position, the compression degree of the first spring 43 is different,
Third active force caused by first spring 43 but hardly happens variation, in this way, the growth conveyed in the first pumping mechanism
Under different conditions, the difference of the first active force and the second active force does not change the pressure of medical fluid substantially, and the first active force
It is generated respectively by the pressure of the growth medical fluid in the first chamber 415 and the second chamber 416 with the second active force, therefore, in two chambers
The pressure difference of growth medical fluid be basically unchanged, this explanation, the difference by the pressure of the growth medical fluid of 56 front and back of duct is constant, such as
This, when the pressure for the water that the first pumping mechanism is conveyed remains unchanged, the area of the flow-passing surface in duct 56 is remained unchanged, according to
Channel theory passes through the growth medical fluid in the duct 56 if the difference by the pressure of the growth medical fluid of 56 front and back of duct is constant
Flow is constant, so that the amount entered in mixing chamber 11 be made not change.In conclusion the concentration regulating mechanism of above structure
40 advantage is：When the pressure for the water that the first pumping mechanism is conveyed is stablized (that is, into the water quantity holding in mixing chamber 11
It is constant), the pressure change for the growth medical fluid that will not be conveyed into the growth medical fluid in mixing chamber 11 by the second pumping mechanism 30
And change, so that it is constant to be able to maintain the melting concn for growing medical fluid and water.
2, above-described embodiment another advantage is that：As already mentioned above, it can be realized into mixing chamber 11
Water and enter mixing chamber 11 growth medical fluid amount it is synchronous variation so that grow medical fluid concentration not by the change of water and
Change, concrete reason is：
As described above, being remained unchanged by the pressure difference of the growth medical fluid of the front and back in duct 56, the overcurrent in duct 56
The area in face is changeable, when the pressure for the water that the first pumping mechanism is conveyed increases and increases the amount of the water entered in mixing chamber 11
When more, the increase of hydraulic pressure according to channel theory, passes through the growth medical fluid in duct 56 so that the area of the flow-passing surface in duct 56 increases
Flow increase so that into the growth medical fluid in mixing chamber 11 with enter water amount increase and synchronize increase, correspondingly, work as water
Pressure reduce and enter the water in mixing chamber 11 amount it is less when, the reduction of hydraulic pressure so that the area of the flow-passing surface in duct 56 reduces,
Reduced by the flow of the growth medical fluid in duct 56 so that into the growth medical fluid in mixing chamber 11 with the reduction for the amount for entering water
And synchronize reduction, with it is final guarantee growth medical fluid and water melting concn will not with enter mixing chamber 11 in water amount change and
Change.
It should illustrate：The flow-passing surface in duct 56 is the concept in hydrodynamics, passes through the place in duct 56 most for fluid
Small bore is used to limit the flow of fluid.
