J, repeating step b are to step I.

The switching principle of the switching principle of the switching principle of main valve of the present invention and cleaning valve and injection valve and common water intaking valve or common electromagnetic valve is identical, all is that the epicoele of the relief hole control spool that covers through open and close valve and the pressure differential of cavity of resorption reach open and close valve; Through out-of-date, the relief hole shut off valve on the valve gap just is closed as current, and the relief hole opening valve on the valve gap just is unlocked, and is specific as follows:

Place spool in the valve body, spool has the hole of up/down perforation, and spool is divided into epicoele and cavity of resorption with valve inner; Cavity of resorption comprises intake antrum and water chamber, and the valve body epicoele communicates with cavity of resorption through the aperture on the spool, when relief hole is in closed condition and has current to get into; Part water reaches the valve body epicoele through the aperture on the spool, and this moment, spool received the downward applied pressure of water and the water in the intake antrum in the epicoele applied pressure that makes progress, and downward pressure size multiply by the cross section of epicoele for hydraulic pressure; Be the cross section of spool, the size that upwards pressure multiply by the cross section of intake antrum for hydraulic pressure, because hydraulic pressure is the same; And the cross section of intake antrum is much smaller than the cross section of epicoele; Therefore the downward pressure that receives of spool is greater than upwarding pressure, and spool is in shifting state down, cuts off the connection of intake antrum and water chamber.This state is called the closed condition of this valve body.

When relief hole was in opening, the valve body epicoele communicated with the external world through relief hole, because the hole diameter on the spool is less than the diameter of relief hole on the valve gap; When current got into, the water that reaches the valve body epicoele through the aperture on the spool went out valve body through letting out little pressure orifice flow very soon, and the downward pressure that spool receives upwards pressure less than what it received; When arriving a certain pressure differential; Spool is in raised state, and intake antrum is communicated with water chamber, and current flow into water chamber from intake antrum.This state is called the opening of this valve body.

Can find out that to sum up when current passed through, relief hole was closed and then caused valve to be closed, relief hole is opened and is then caused opening of valves.Therefore, control the switching of relief hole, just controlled the switching of valve, thus the outflow of controlled water flow.

Workflow of the present invention is following:

A. water saving fixtures being sprayed in cleaning of the present invention is fixedly mounted in the water tank; The lower end that makes water inlet pipe and playpipe is outside water tank; Be connected water inlet pipe with external water source; Connect flexible pipe on playpipe and the scavenge pipe, another termination of the flexible pipe that connects on the said playpipe is to bedpan middle part or bottom or blow-off line inlet bottom, and another termination of the flexible pipe that connects on the said scavenge pipe is to bedpan top or toroidal race.Anhydrous in the water tank at this moment, main valve buoyancy aid mechanism and cleaning valve buoyancy aid mechanism and injection valve controlling organization do not float.

When main valve buoyancy aid mechanism does not float; The jointing that is connected with main valve buoyancy aid mechanism on the main valve cursor is the decline state; Because the resilient plug of the main valve valve gap relief hole of main valve cursor top and jointing are in the both sides of rotating fulcrum; Therefore the resilient plug on the main valve cursor is a propradation, and the main valve relief hole is an open mode.

When cleaning valve buoyancy aid mechanism does not float; The jointing that is connected with cleaning valve buoyancy aid mechanism on the cleaning valve cursor is the decline state; Because the resilient plug of the cleaning valve valve gap relief hole of cleaning valve cursor top and jointing are at the homonymy of rotating fulcrum; Therefore the resilient plug on the cleaning valve cursor is the decline state, and the cleaning valve relief hole is a closed condition; Injection valve controlling organization and cleaning valve controlling organization are the parallel controlling organizations of two covers, and principle is the same, so when injection valve buoyancy aid mechanism did not float, the injection valve relief hole also was a closed condition.

B. open external water source, current are from the intake antrum of water inlet pipe entering main valve, because the main valve relief hole is an open mode, when current passed through, main valve was opened, and main valve intake antrum and water chamber are connected; Current are successively through main valve intake antrum, main valve water chamber, entering cleaning valve intake antrum and injection valve intake antrum; Or current are successively through main valve intake antrum, main valve water chamber, anti-siphon valve intake antrum, anti-siphon valve water chamber, entering cleaning valve intake antrum and injection valve intake antrum; Because cleaning valve and injection valve relief hole are closed condition; Cleaning valve and injection valve spool are in shifting state down; Cleaning valve is not communicated with the intake antrum and the water chamber of injection valve, and water chamber and the cleaning valve of current through being positioned at main valve gets into water tank with delivery port on the passage that the intake antrum of injection valve is connected mutually.

C. after external water source continued to flow into a period of time, the water tank middle water level rose, because the different main valve buoyancy aid mechanisms that can make with the water inlet structure of cleaning valve buoyancy aid jar and injection valve buoyancy aid jar of main valve buoyancy aid jar at first float; The jointing that is connected with main valve buoyancy aid mechanism on the main valve cursor rises; The resilient plug of the main valve valve gap top on the main valve cursor descends, and the main valve relief hole is closed, and main valve is closed; The intake antrum and the water chamber of main valve are not communicated with, and stop to the water supply of water tank.

D. after main valve is closed; Cleaning valve buoyancy aid mechanism and injection valve buoyancy aid mechanism float; The jointing that drives on cleaning valve and the injection valve cursor rises, thereby the resilient plug on cleaning valve and the injection valve cursor is also risen, and the relief hole of cleaning valve and injection valve is opened; So but since this moment main valve closed and do not have current to pass through, cleaning valve and injection valve are in a kind of state to be opened.

E. water tank opening water discharge; Drawdown in the water tank; The water yield of main valve buoyancy aid jar is greater than the water yield of cleaning valve and injection valve buoyancy aid jar when making water outlet owing to the one way valve of main valve buoyancy aid jar bottom is different with the one way valve opening degree of cleaning valve and injection valve buoyancy aid jar bottom; Therefore main valve buoyancy aid mechanism sinks prior to cleaning valve and injection valve buoyancy aid mechanism, and the jointing that is connected with main valve buoyancy aid mechanism on the main valve cursor descends, and the resilient plug on the main valve cursor rises; Open the main valve relief hole, main valve is opened; This moment is because the water yield of cleaning valve and injection valve buoyancy aid jar is few; The buoyancy aid mechanism of cleaning valve and injection valve still is in float state; The relief hole of cleaning valve and injection valve still is in open mode, and current are through out-of-date, and cleaning valve and injection valve are opened; External water source arrives the position of required injection from scavenge pipe and playpipe, and wherein one current get into water tank through delivery port.

F. because cleaning valve is also different with the one way valve opening degree of injection valve buoyancy aid jar bottom; The water yield of cleaning valve buoyancy aid jar is greater than the water yield of injection valve buoyancy aid jar when making water outlet; After the water outlet of cleaning valve buoyancy aid jar acquired a certain degree, the water shortage in the cleaning valve buoyancy aid jar was to let cleaning valve buoyancy aid mechanism float, and cleaning valve buoyancy aid mechanism sinks; The jointing that is connected with cleaning valve buoyancy aid mechanism on the cursor of cleaning valve descends; Resilient plug on the cleaning valve cursor descends, and the cleaning valve relief hole is closed, and cleaning valve is closed.

G. last; After the water outlet of injection valve buoyancy aid jar also acquired a certain degree, the water yield in the injection valve buoyancy aid jar also was not enough to let injection valve buoyancy aid mechanism float, and injection valve buoyancy aid mechanism sinks; The jointing that is connected with injection valve buoyancy aid mechanism on the cursor of injection valve descends; Resilient plug on the injection valve cursor descends, and the injection valve relief hole is closed, and injection valve cuts out.And

H. repeating step b is to step g.

The invention has the beneficial effects as follows:

Simple installation; Water inlet pipe is connected with external water source; Connect flexible pipe on playpipe and the scavenge pipe; Another termination of the flexible pipe that connects on the said playpipe is to bedpan middle part or bottom or blow-off line inlet bottom, and another termination of the flexible pipe that connects on the said scavenge pipe can be used to bedpan top or toroidal race.

With low cost, the present invention uses the switching of buoyancy aid mechanism automatic control valve, compares with existing electromagnetic valve etc., and is with low cost.

Automatically control is washed away strong water saving, when cistern water-discharging; Clean the playpipe and the scavenge pipe automatic water jetting that spray in the water saving fixtures, water inlet pipe, main valve, injection valve, cleaning valve, playpipe, scavenge pipe form path, and external water source sprays water saving fixtures through cleaning and directly ejects from playpipe and scavenge pipe; The flow action that ejects from playpipe is in the bedpan middle part or bottom or blow-off line inlet bottom; The water that promotion is discharged from water tank washes, and the flow action that ejects from scavenge pipe is in bedpan top or toroidal race, the external water source of the present invention's different hydraulic pressure capable of using; The water pressure that ejects is big, rinses water saving well.

The course of work when introducing cleaning of the present invention below and spraying water saving fixtures 71 and be installed in the water tank 72:

Consult Figure 29, Figure 20, anhydrous originally in water tank 72, it is shown in figure 20 that water saving fixtures 71 outside each unit status are sprayed in cleaning of the present invention at that time; The main valve buoyancy aid mechanism 45 and the buoyancy aid mechanism 43 of cleaning valve and injection valve all are shifting state down; Shown in arrow X arrow Y arrow Z among Figure 20, consult Figure 26, Figure 27, main valve relief hole 20 was opened at that time; Cleaning valve relief hole 21 is closed, and injection valve relief hole 22 is closed; Because do not have external water source or tap water; The spool that main valve and cleaning valve and injection valve are inner is shifting state down because of the elasticity of Elastic valve core diaphragm 64; The anti-siphon spool 58 that anti-siphon valve is inner is because deadweight also is shifting state down, and main valve buoyancy aid jar A bottom also is shifting state down with the one way valve 69 of cleaning valve buoyancy aid jar B bottom and injection valve buoyancy aid jar C bottom because of deadweight;

During to water inlet pipe 14 water inlets of water tank 72 outer bottoms, consult 20a as external water source or tap water, in main valve intake antrum 2, just have current A and flow into, current A makes on the main valve plug and moves, and just has current B to flow in the main valve water chamber 3; Consult Figure 20 b; The passage of current B through being connected between main valve water chamber 3 and the anti-siphon valve intake antrum 4; Just there is current C to flow in the anti-siphon valve intake antrum 4; Current C makes on the anti-siphon spool 58 and moves, and anti-siphon valve water chamber 5 just has current D to flow out, and moves the anti-siphon air channel of having sealed on total valve gap 19 26 that is communicated with up and down on the anti-siphon spool 58; Consult Figure 20 c, current D just has current E to flow into through the passage that anti-siphon valve water chamber 5 is connected with cleaning valve intake antrum 8 in the cleaning valve intake antrum 8; Again consult Figure 20 a; Current E can arrive delivery port 18 along cleaning valve intake antrum 8; Just having current F in the delivery port 18 flows out; Just have current G in the filling pipe 55 on the water out adapter 54 and flow out, just have current H in the outlet pipe 56 and flow out, the current G that from filling pipe 55, flows out can insert bedpan and be used for the bedpan moisturizing; The current H that from outlet pipe 56, flows out flows into water tank, and water tank begins to get into water inlet state (cleaning valve and injection valve can not be opened because the buoyancy aid mechanism 43 of cleaning valve and injection valve moves down that cleaning valve relief hole 21 and injection valve relief hole 22 are closed at that time);

Each unit status of outside of cleaning injection water saving fixtures 71 of the present invention at that time is shown in figure 20, shown in the resilient plug 63 of main valve and cleaning valve and injection valve, the spool that reaches main valve and cleaning valve and injection valve, the state that reaches anti-siphon spool 58 such as Figure 20 a, Figure 20 b, Figure 20 c.

Consult Figure 21; Flow in the water tank 72 along with current H pours from outlet pipe 56, water level raises gradually in the water tank 72, owing in the bottom of main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and injection valve buoyancy aid jar C one way valve 69 is arranged all; So water level rises to the process of upper edge portion from the bottom of main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and injection valve buoyancy aid jar C in water tank 72; The one way valve 69 of main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and injection valve buoyancy aid jar C bottom because receive moves in the buoyancy and seals unidirectional valve opening 47, so main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and injection valve buoyancy aid jar C can not be intake, has only the infiltration of minute quantity; Be not enough to produce buoyancy and make main valve buoyancy aid mechanism 45 and cleaning valve buoyancy aid mechanism 43 and injection valve buoyancy aid mechanism 43 come-ups; Have only when water level has risen to main water inlet position, the top of main valve buoyancy aid jar A 50, current just can get in the main valve buoyancy aid jar A, after water gets into from main water inlet position 50; Main valve buoyancy aid mechanism 45 in it just can float owing to receiving buoyancy function; Thereby main valve relief hole 20 is closed, and the final plant closure main valve, after main valve is closed; Filling pipe 55 on the water out adapter 54 and outlet pipe 56 also go out with regard to anhydrous, and the water inlet of water tank has just stopped; Main valve buoyancy aid mechanism 45 was raised state shown in arrow X among Figure 21 at that time, and shifting state was shown in arrow Y arrow Z among Figure 20 under cleaning valve buoyancy aid mechanism 43 and injection valve buoyancy aid mechanism 43 also were;

It is shown in figure 21 that water saving fixtures 71 outside each unit status are sprayed in cleaning of the present invention at that time; The resilient plug 63 of main valve and cleaning valve and injection valve, and the state such as Figure 21 a of the spool of main valve and cleaning valve and injection valve shown in, do not had the inner anti-siphon spool 58 of the anti-siphon valve of impact of current to move down again because conduct oneself with dignity.

Consult Fig. 8 a; Because the main water inlet position 50 of main valve buoyancy aid jar A sidewall upper edge is lower than the upper edge of cleaning valve buoyancy aid jar B and injection valve buoyancy aid jar C; Get into so when having water to get in the main valve buoyancy aid jar A, also do not have water in cleaning valve buoyancy aid jar B and the injection valve buoyancy aid jar C, have only when the water in the main valve buoyancy aid jar A advance full after, just have water and intake from the cleaning valve buoyancy aid jar that interconnects on the share common sidewalls top of main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and 51 flow in the cleaning valve buoyancy aid jar B; By the time after flowing into water in the cleaning valve buoyancy aid jar B and completely arriving to a certain degree; Cleaning valve buoyancy aid mechanism 43 in the cleaning valve buoyancy aid jar B just can float owing to receiving buoyancy function, thereby cleaning valve relief hole 21 is opened, and this moment, main valve was closed; Cleaning valve has not had water inlet; Though cleaning valve relief hole 21 is opened and also can be opened, cleaning valve just is in a kind of opening of treating, as long as can be opened at once once there being current to flow into cleaning valve intake antrum 6;

Equally; Water in the injection valve buoyancy aid jar C also has only after the water in the main valve buoyancy aid jar A advances to expire; Just have water and flow in the injection valve buoyancy aid jar C from the injection valve buoyancy aid jar that interconnects on the share common sidewalls top of main valve buoyancy aid jar A and injection valve buoyancy aid jar C water inlet position 52, after flowing into water in the injection valve buoyancy aid jar C by the time and completely arrive to a certain degree, the injection valve buoyancy aid mechanism 43 in the injection valve buoyancy aid jar C just meeting float owing to receiving buoyancy function; Thereby injection valve relief hole 22 is opened; And this moment, main valve was closed, and injection valve has not had water inlet, also can not be opened though injection valve relief hole 22 is opened; Injection valve just is in a kind of opening of treating, as long as can be opened at once once there being current to flow into injection valve intake antrum 8; Main valve buoyancy aid mechanism 45 all was raised state with the buoyancy aid mechanism 43 of cleaning valve and injection valve at that time, shown in arrow X arrow Y arrow Z among Figure 22;

It is shown in figure 22 that water saving fixtures 71 outside each unit status are sprayed in cleaning of the present invention at that time, the resilient plug 63 of main valve and cleaning valve and injection valve, reach main valve and cleaning valve and injection valve the state of spool shown in Figure 22 a.

Consult Figure 29, Figure 23; When the drain assembly 73 in opening water tank 72 makes cistern water-discharging; Along with the quick decline of water level in the water tank 72, the one way valve 69 of the outer bottom of main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and injection valve buoyancy aid jar C is not owing to there has been buoyancy function to move down, and the water in main valve buoyancy aid jar A and cleaning valve buoyancy aid jar B and the injection valve buoyancy aid jar C will be from they unidirectional valve opening 47 outflows of bottom separately; But because the opening degree of the one way valve 69 of main valve buoyancy aid jar A bottom is maximum; Secondly be the opening degree of the one way valve 69 of cleaning valve buoyancy aid jar B bottom, the opening degree of the one way valve 69 of injection valve buoyancy aid jar C bottom is minimum, so the emptying at once of the water in the main valve buoyancy aid jar A; Main valve buoyancy aid mechanism 45 also just moves down at once thereupon, thereby main valve relief hole 20 is unlocked; And the water in cleaning valve buoyancy aid jar B and the injection valve buoyancy aid jar C can not flow to end at once, and cleaning valve and injection valve buoyancy aid mechanism 43 also can be the come-up state within a certain period of time, just can also make cleaning valve relief hole 21 and injection valve relief hole 22 be held open state;

Consult 23a, after main valve relief hole 20 was unlocked, the current A in main valve intake antrum 2 will make on the main valve plug and move, and just had current B to flow in the main valve water chamber 3; Consult Figure 23 b, the passage of current B through being connected between main valve water chamber 3 and the anti-siphon valve intake antrum 4 just has current C to flow in the anti-siphon valve intake antrum 4, and current C makes on the anti-siphon spool 58 and moves, and anti-siphon valve water chamber 5 just has current D to flow out;

Consult Figure 23 c; On the one hand, current D just has current E to flow into through the passage that anti-siphon valve water chamber 5 is connected with injection valve intake antrum 8 in the injection valve intake antrum 8; Current E makes to spray on the spool and moves; Make promptly that also injection valve is unlocked, just have current I to flow out in the injection valve water chamber 9, have current J to eject on the playpipe 16;

Consult Figure 23 d; On the other hand, current D can just have current K to flow into through the passage of preventing that siphon valve water chamber 5 is connected with cleaning valve intake antrum 6 simultaneously in the cleaning valve intake antrum 6; Current K makes to clean on the spool and moves; Make promptly that also cleaning valve is unlocked, just have current L to flow out in the cleaning valve water chamber 7, have current M to eject on the scavenge pipe 15;

Again consult Figure 23 a; Current E can arrive delivery port 18 along injection valve intake antrum 8 simultaneously, just has current F in the delivery port 18 and flows out, and just has current G in the filling pipe 55 on the water out adapter 54 and flows out; Just having current H in the outlet pipe 56 flows out; The current G that from filling pipe 55, flows out can insert bedpan and be used for the bedpan moisturizing, and the current H that from outlet pipe 56, flows out flows into water tank, and water tank gets into the water inlet state simultaneously;

Shifting state was shown in arrow X among Figure 23 under main valve buoyancy aid mechanism 45 was at that time, and cleaning valve buoyancy aid mechanism 43 and injection valve buoyancy aid mechanism 43 also are raised state shown in arrow Y arrow Z among Figure 23;
