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, is all that the relief hole that covers by open and close valve is controlled the epicoele of spool and the pressure differential of cavity of resorption reaches open and close valve; When having current through out-of-date, the relief hole shut off valve on valve gap is just closed, and the relief hole opening valve on valve gap is just unlocked, specific as follows:

In valve body, place spool, spool has the hole of up/down perforation, spool is divided into epicoele and cavity of resorption by valve inner, cavity of resorption comprises intake antrum and water chamber, valve body epicoele communicates with cavity of resorption by the aperture on spool, at relief hole when closed condition has current to enter, part water reaches valve body epicoele by the aperture on spool, now spool is subject to the downward applied pressure of water in epicoele and the water in the intake antrum applied pressure that makes progress, downward pressure size is multiplied by the cross section of epicoele for hydraulic pressure, it is the cross section of spool, the size that upwards pressure is multiplied 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 spool is subject to is greater than and upwards pressure, spool is in lower shifting state, cut off the connection of intake antrum and water chamber.This state is called the closed condition of this valve body.

At relief hole during in opening, valve body epicoele communicates with the external world by relief hole, because the hole diameter on spool is less than the diameter of relief hole on valve gap, when current enter, the water that reaches valve body epicoele by the aperture on spool flows out valve body by letting out little pressure hole very soon, and the downward pressure that spool is subject to is less than upwarding pressure that it is subject to, 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.

In summary it can be seen, when current pass through, relief hole is closed and is caused valve to be closed, and relief hole is opened and caused valve to be opened.Therefore, control the switching of relief hole, just controlled the switching of valve, thereby controlled the outflow of current.

Workflow of the present invention is as follows:

A. cleaning of the present invention being sprayed to water-saving valve is fixedly mounted in water tank, make the lower end of water inlet pipe and playpipe outside water tank, water inlet pipe is connected with external water source, connecting hose on playpipe and scavenge pipe, another termination of the flexible pipe connecting on described playpipe is in the middle part of bedpan or bottom bottom or blow-off line entrance, another termination of the flexible pipe connecting on described scavenge pipe is to bedpan top or toroidal race.Now anhydrous in water tank, 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 being connected with main valve buoyancy aid mechanism on main valve cursor is decline state, due to the resilient plug of the main valve valve gap relief hole top of main valve cursor and the jointing both sides at rotating fulcrum, therefore the resilient plug on main valve cursor is propradation, and main valve relief hole is open mode.

When cleaning valve buoyancy aid mechanism does not float, the jointing being connected with cleaning valve buoyancy aid mechanism on cleaning valve cursor is decline state, due to the resilient plug of the cleaning valve valve gap relief hole top of cleaning valve cursor and the jointing homonymy at rotating fulcrum, therefore the resilient plug on cleaning valve cursor is decline state, and cleaning valve relief hole is 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 does not float, injection valve relief hole is also closed condition.

B. open external water source, current enter the intake antrum of main valve from water inlet pipe, and because main valve relief hole is open mode, when current pass through, main valve is opened, and main valve intake antrum and water chamber are connected; Current successively by main valve intake antrum, main valve water chamber, enter cleaning valve intake antrum and injection valve intake antrum; Or current successively by main valve intake antrum, main valve water chamber, anti-siphon valve intake antrum, anti-siphon valve water chamber, enter 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 lower shifting state, cleaning valve is not communicated with intake antrum and the water chamber of injection valve, and current enter water tank by the delivery port being positioned on the water chamber of main valve and passage that cleaning valve is connected mutually with the intake antrum of injection valve.

C. external water source continues to flow into after a period of time, rise in Water in Water Tanks position, because first the different main valve buoyancy aid mechanisms that can make of water inlet structure of main valve buoyancy aid tank and cleaning valve buoyancy aid tank and injection valve buoyancy aid tank float, the jointing being connected with main valve buoyancy aid mechanism on main valve cursor rises, the resilient plug of the main valve valve gap top on main valve cursor declines, and main valve relief hole is closed, and main valve is closed, intake antrum and the water chamber of main valve are not communicated with, and to the water supply of water tank, stop.

D. after main valve is closed, cleaning valve buoyancy aid mechanism and injection valve buoyancy aid mechanism float, drive the jointing on cleaning valve and injection valve cursor to rise, thereby make the resilient plug on cleaning valve and injection valve cursor also increase, the relief hole of cleaning valve and injection valve is opened, so but closed and do not have current to pass through due to main valve now, cleaning valve and injection valve are in a kind of state to be opened.

E. water tank opening water discharge, in water tank, water level declines, while making water outlet because the one way valve of main valve buoyancy aid tank bottom is different with the one way valve opening degree of cleaning valve and injection valve buoyancy aid tank bottom, the water yield of main valve buoyancy aid tank is greater than the water yield of cleaning valve and injection valve buoyancy aid tank, therefore main valve buoyancy aid mechanism sinks prior to cleaning valve and injection valve buoyancy aid mechanism, the jointing being connected with main valve buoyancy aid mechanism on main valve cursor declines, resilient plug on main valve cursor rises, open main valve relief hole, main valve is opened; Now because the water yield of cleaning valve and injection valve buoyancy aid tank is few, the buoyancy aid mechanism of cleaning valve and injection valve is still in float state, the relief hole of cleaning valve and injection valve is still in open mode, current are through out-of-date, cleaning valve and injection valve are opened, external water source arrives the position of required injection from scavenge pipe and playpipe, wherein one current enter water tank by delivery port.

F. because cleaning valve is also different from the one way valve opening degree of injection valve buoyancy aid tank bottom, while making water outlet, the water yield of cleaning valve buoyancy aid tank is greater than the water yield of injection valve buoyancy aid tank, after the water outlet of cleaning valve buoyancy aid tank acquires a certain degree, water shortage in cleaning valve buoyancy aid tank is to allow cleaning valve buoyancy aid mechanism float, cleaning valve buoyancy aid mechanism sinks, the jointing being connected with cleaning valve buoyancy aid mechanism on the cursor of cleaning valve declines, resilient plug on cleaning valve cursor declines, cleaning valve relief hole is closed, and cleaning valve is closed.

G. last, after the water outlet of injection valve buoyancy aid tank also acquires a certain degree, the water yield in injection valve buoyancy aid tank is also not enough to allow injection valve buoyancy aid mechanism float, injection valve buoyancy aid mechanism sinks, the jointing being connected with injection valve buoyancy aid mechanism on the cursor of injection valve declines, resilient plug on injection valve cursor declines, and 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, connecting hose on playpipe and scavenge pipe, another termination of the flexible pipe connecting on described playpipe is in the middle part of bedpan or bottom bottom or blow-off line entrance, another termination of the flexible pipe connecting on described scavenge pipe, to bedpan top or toroidal race, can be used.

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

Automatically control, wash away strong water saving, when cistern water-discharging, clean the playpipe and the scavenge pipe automatic water jetting that spray in water-saving valve, water inlet pipe, main valve, injection valve, cleaning valve, playpipe, scavenge pipe forms path, external water source directly ejects from playpipe and scavenge pipe through cleaning injection water-saving valve, the flow action ejecting from playpipe is in the middle part of bedpan or bottom bottom or blow-off line entrance, the water that promotion is discharged from water tank rinses, the flow action ejecting from scavenge pipe is in bedpan top or toroidal race, the present invention can utilize the external water source of different hydraulic pressure, the water pressure ejecting is large, rinse water saving well.

The switching principle of comprehensive aforesaid main valve and cleaning valve and injection valve, can obtain drawing a conclusion: in the situation that cleaning injection water-saving valve of the present invention connects external water source, when main valve buoyancy aid mechanism 45 floating, main valve is closed, when main valve buoyancy aid mechanism 45 moves down, main valve is unlocked; When cleaning valve buoyancy aid mechanism 43 floating, cleaning valve is unlocked or in can opening, when cleaning valve buoyancy aid mechanism 43 moves down, cleaning valve be closed; When injection valve buoyancy aid mechanism 43 floating, injection valve is unlocked or in can opening, when injection valve buoyancy aid mechanism 43 moves down, injection valve be closed.

Introducing cleaning of the present invention below sprays water-saving valve 71 and is arranged on the course of work of water tank 72 when interior:

Consult Figure 29, Figure 20, interior originally anhydrous at water tank 72, cleaning of the present invention is at that time sprayed outside each unit status of water-saving valve 71 as shown in figure 20, main valve buoyancy aid mechanism 45 and the buoyancy aid mechanism 43 of cleaning valve and injection valve are all lower shifting state, as shown in arrow X arrow Y arrow Z in 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 without external water source or tap water, the spool of main valve and cleaning valve and injection valve inside is lower shifting state because of the elasticity of Elastic valve core diaphragm 64, the anti-siphon spool 58 of anti-siphon valve inside is because deadweight is also lower shifting state, and main valve buoyancy aid tank A bottom is also lower shifting state with the one way valve 69 of cleaning valve buoyancy aid tank B bottom and injection valve buoyancy aid tank C bottom because of deadweight;

When having external water source or tap water to intake to the water inlet pipe 14 of water tank 72 outer bottoms, consult 20a, in main valve intake antrum 2, just have current A and flow into, current A makes to move on main valve plug, just has current B to flow in main valve water chamber 3; Consult Figure 20 b, current B is by the passage being connected between main valve water chamber 3 and anti-siphon valve intake antrum 4, in anti-siphon valve intake antrum 4, just there is current C to flow into, current C makes to move on anti-siphon spool 58, anti-siphon valve water chamber 5 just has current D to flow out, and moves the anti-siphon air channel 26 being communicated with up and down having sealed on total valve gap 19 on anti-siphon spool 58; Consult Figure 20 c, the passage that current D is connected with cleaning valve intake antrum 8 by anti-siphon valve water chamber 5, just has current E to flow in cleaning valve intake antrum 8; Again consult Figure 20 a, current E can arrive delivery port 18 along cleaning valve intake antrum 8, in delivery port 18, just having current F flows out, in filling pipe 55 on water out adapter 54, just having current G flows out, in outlet pipe 56, just having current H flows out, the accessible bedpan of current G flowing out from filling pipe 55 is for bedpan moisturizing, the current H flowing out from outlet pipe 56 flows into water tank, and water tank started to enter into water state (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, cleaning valve and injection valve can not be opened at that time);

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

Consult Figure 21, along with continuously outflowing from outlet pipe 56, current H flows in water tank 72, the interior water level of water tank 72 raises gradually, because one way valve 69 is arranged at the bottom at main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C, so rise to along in the process of portion from the bottom of main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C at the interior water level of water tank 72, the one way valve 69 of main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C bottom is because be subject to moving and closed check valve hole 47 in buoyancy, so main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C can not intake, only has 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 floatings, only have when water level has risen to main water inlet position, the top of main valve buoyancy aid tank A 50, current just can enter in main valve buoyancy aid tank A from main water inlet position 50, after having water to enter, main valve buoyancy aid mechanism 45 in it just can float owing to being subject to the effect of buoyancy, thereby main valve relief hole 20 is closed, and final plant closure main valve, after main valve is closed, filling pipe on water out adapter 54 55 and outlet pipe 56 also go out with regard to anhydrous, the water inlet of water tank has just stopped, main valve buoyancy aid mechanism 45 was raised state as shown in arrow X in Figure 21 at that time, and cleaning valve buoyancy aid mechanism 43 and injection valve buoyancy aid mechanism 43 are also lower shifting state as shown in arrow Y arrow Z in Figure 20,

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

Consult Fig. 8 a, because the 50 upper edges lower than cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C, main water inlet position on edge on main valve buoyancy aid tank A sidewall, so also not having water in cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C while having water to enter in main valve buoyancy aid tank A enters, only have water in main valve buoyancy aid tank A enter full after, just having water flows in cleaning valve buoyancy aid tank B from the cleaning valve buoyancy aid tank the interconnecting water inlet position 51 on the share common sidewalls top of main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B, by the time flow into water in cleaning valve buoyancy aid tank B completely to a certain extent after, cleaning valve buoyancy aid mechanism 43 in cleaning valve buoyancy aid tank B just can float owing to being subject to the effect of buoyancy, thereby cleaning valve relief hole 21 is opened, and now main valve has been closed, cleaning valve has not had water inlet, although cleaning valve relief hole 21 is opened and also can be opened, cleaning valve is just in a kind of opening for the treatment of, as long as can be opened at once once there being current to flow into cleaning valve intake antrum 6,

Equally, after water in injection valve buoyancy aid tank C also only has the water in main valve buoyancy aid tank A to enter completely, just having water flows in injection valve buoyancy aid tank C from the injection valve buoyancy aid tank the interconnecting water inlet position 52 on the share common sidewalls top of main valve buoyancy aid tank A and injection valve buoyancy aid tank C, by the time flow into water in injection valve buoyancy aid tank C completely to a certain extent after, injection valve buoyancy aid mechanism 43 in injection valve buoyancy aid tank C just can float owing to being subject to the effect of buoyancy, thereby injection valve relief hole 22 is opened, and now main valve has been closed, injection valve has not had water inlet, although injection valve relief hole 22 is opened and also can be opened, injection valve is just in a kind of opening for the treatment of, 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 was all raised state with the buoyancy aid mechanism 43 of cleaning valve and injection valve at that time, as shown in arrow X arrow Y arrow Z in Figure 22,

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

Consult Figure 29, Figure 23, when the drain assembly 73 in opening water tank 72 makes cistern water-discharging, fast-descending along with water tank 72 interior water levels, the one way valve 69 of the outer bottom of main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C is owing to not had the effect of buoyancy to move down, water in main valve buoyancy aid tank A and cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank 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 tank A bottom be maximum, secondly be the opening degree of the one way valve 69 of cleaning valve buoyancy aid tank B bottom, the opening degree of the one way valve 69 of injection valve buoyancy aid tank C bottom is minimum, so the water in main valve buoyancy aid tank A will be at once emptying, main valve buoyancy aid mechanism 45 also just moves down at once thereupon, thereby main valve relief hole 20 is unlocked, and water in cleaning valve buoyancy aid tank B and injection valve buoyancy aid tank C can not flow to end at once, cleaning valve and injection valve buoyancy aid mechanism 43 also can be floating state within a certain period of time, namely 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 is unlocked, the current A in main valve intake antrum 2 will make to move on main valve plug, just has current B to flow in main valve water chamber 3; Consult Figure 23 b, current B, by the passage being connected between main valve water chamber 3 and anti-siphon valve intake antrum 4, just has current C to flow in anti-siphon valve intake antrum 4, and current C makes to move on anti-siphon spool 58, and anti-siphon valve water chamber 5 just has current D to flow out;

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

Consult Figure 23 d, on the other hand, the passage that current D can be connected with cleaning valve intake antrum 6 by anti-siphon valve water chamber 5 simultaneously, in cleaning valve intake antrum 6, just there is current K to flow into, current K makes to clean on spool and moves, also make cleaning valve be unlocked, in cleaning valve water chamber 7, just have current L to flow out, on scavenge pipe 15, have current M to eject;

Again consult Figure 23 a, current E can arrive delivery port 18 along injection valve intake antrum 8 simultaneously, in delivery port 18, just having current F flows out, in filling pipe 55 on water out adapter 54, just having current G flows out, in outlet pipe 56, just having current H flows out, the accessible bedpan of current G flowing out from filling pipe 55 is for bedpan moisturizing, and the current H flowing out from outlet pipe 56 flows into water tank, and water tank enters into water state simultaneously;

Main valve buoyancy aid mechanism 45 was lower shifting state as shown in arrow X in Figure 23 at that time, and cleaning valve buoyancy aid mechanism 43 and injection valve buoyancy aid mechanism 43 are also raised state as shown in arrow Y arrow Z in Figure 23;

Cleaning of the present invention is at that time sprayed outside each unit status of water-saving valve 71 as shown in figure 23, and the spool of the resilient plug 63 of main valve and cleaning valve and injection valve and main valve and cleaning valve and injection valve and the state of anti-siphon spool 58 are as shown in Figure 23 a, Figure 23 b, Figure 23 c, Figure 23 d.

Consult Figure 24, Figure 24 a, Deng being after a bit of time, after 3 seconds, then the water yield in cleaning valve buoyancy aid tank B is flow to end gradually, the cleaning valve buoyancy aid mechanism 43 of portion moves down owing to having lost the effect of buoyancy within it, will make like this cleaning valve relief hole 21 be closed, clean spool and move down, cleaning valve is closed;

Cleaning of the present invention is at that time sprayed outside each unit status of water-saving valve 71 as shown in figure 24, and the state of the spool of the resilient plug 63 of main valve and cleaning valve and injection valve and main valve and cleaning valve and injection valve is as shown in Figure 24 a.

Again consult Figure 20, Deng after after a bit of time, after 8 seconds, then the water yield in injection valve buoyancy aid tank C is also flow to end gradually, the injection valve buoyancy aid mechanism 43 of portion moves down owing to having lost the effect of buoyancy within it, will make like this injection valve relief hole 22 also be closed, spray spool and move down, injection valve is also closed;

Each unit status of outside of cleaning injection water-saving valve 71 of the present invention as shown in figure 20 at that time, main valve buoyancy aid mechanism 45 and the buoyancy aid mechanism 43 of cleaning valve and injection valve are all lower shifting state, as shown in arrow X arrow Y arrow Z in Figure 20, the spool of the resilient plug 63 of main valve and cleaning valve and injection valve and main valve and cleaning valve and injection valve and the state of anti-siphon spool 58 are as shown in Figure 20 a, Figure 20 b, Figure 20 c.
