Flushing controller 2 is equipped with maintenance button, can directly open closestool drain valve 4 after pressing maintenance button；The punching
The function that controller 2 is equipped with failure alarm signal output is washed, the failure to match can be installed in aircraft instrument and meter monitor area
Lamp device facilitates monitoring vacuum toilet state.
Refering to known to attached drawing 1, Fig. 2, Fig. 3: the purging method of ability of swimming toilet system, packet are discharged with side for the aircraft
Include following steps,
Step 1: pressing push button 1 after entering lavatory, and push button 1 generates pulse signal starting flushing controller 2, rinses
Circulation starts；When pressing push button, flushing controller starts a flush cycle；Flushing controller issues vacuum pump work
Signal；
Step 2: flushing controller 2 issues signal, is powered on flush toilets valve 3, and flush toilets valve 3 is opened；
Under the action of the vacuum suction of vacuum pump 11, flowed into from clear water tanks 8 by the pressurized water purification of supercharging device 9
Flush toilets valve 3, then flowed by backsiphonage valve 5.3 and rinse ring assemblies 5.4, it eventually enters into toilet basin 5.1 and rinses toilet basin 5.1
In dirt；Flush toilets valve 3 is closed after 4S；
Step 3: flushing controller 2 issues signal, is powered on closestool drain valve 4；
Closestool drain valve 4 is opened, and under the action of the vacuum suction of vacuum pump 11, waste water is by being connected to toilet basin 5.1
First drainpipe 6 of lower end is discharged into closestool drain valve 4, then is discharged into waste water tank 10 by closestool drain valve 4 and the second drainpipe 7,
The negative pressure of the second drainpipe and foul water tank that vacuum pump provides is inhaled into waste water in foul water tank；In flush cycle intermediate pump one
Straight work；Since foul water tank is communicated with atmosphere, when aircraft reaches certain height, the air pressure of vacuum toilet and foul water tank
Difference is enough to make in waste water sucking foul water tank, and at this moment vacuum pump stops working in flush cycle；
Flushing controller is for controlling flushing valve in vacuum toilet, closestool drain valve and passing through pipe with closestool vacuum toilet
The working sequence of the vacuum pump of road connection, it is ensured that waste water can timely be discharged and flow into waste water tank after going to the toilet；
After pressing push button 1S, flush toilets valve is initially powered up work, and flush toilets valve conduction time is 1 second, has
Water purification enters flushing ring assemblies from flush toilets valve, eventually enters into closestool and starts the dirt rinsed in toilet basin 5.1；
After button 2 seconds, closestool drain valve 4 is powered on, and closestool drain valve 4 is opened, and closestool drain valve 4 standard-sized sheet to closing entirely
Time is 4S, while flushing controller 2 issues the signal that vacuum pump 11 works when pressing push button 1, and time 8S makes this hair
Bright waste water to be discharged into waste water tank by pipeline under the action of vacuum suction, push button fails in this 8S；
The time that flushing controller 2 of the present invention controls flush toilets valve 3, closestool drain valve 4 and vacuum pump 11 is not limited to
The timing requirements stated, timing requirements can be adjusted according to actual use demand.
In step 2, armature 3.3 is set to overcome first as shown in figure 4, the coil in flush toilets valve 3 generates magnetic force after being powered
The elastic force and sealing ring 3.6 of spring 3.2 disengage, and flushing valve at this time is in the state opened；
After coil blackout in flush toilets valve 3 magnetic force disappear, the first spring 3.2 elastic force effect under, armature 3.3 with
Sealing ring 3.6 is in contact, and flush toilets valve 3 is in close state at this time；The each washing water quantity of flush toilets valve be 220ml ±
40ml。
In step 3, as shown in Fig. 3, Fig. 7, Fig. 8, Fig. 9, Figure 10, brushless motor 4.15 starts turning after being powered, by three
The first canine tooth wheel assembly 4.12 is driven to rotate after grade planetary reduction gear, the first canine tooth wheel assembly 4.12 passes through gear drive drive the
The rotation of two canine tooth wheel assemblies 4.14；Third-level planetary reduction gear is the prior art；
The transmission of first canine tooth wheel assembly 4.12 drives the second largest gear assembly 4.14 to be rotated by 90 °；
When the cam of the first canine tooth wheel assembly 4.12 triggers the first microswitch 4.11, the first microswitch 4.11 feedback
Signal makes brushless motor 4.15 stop working to flushing controller 2, and valve plate 4.23 is in an open position at this time, controls rinsing
Under the control of device 2, by after a certain period of time, brushless motor 4.15 starts to invert, the first canine tooth wheel assembly 4.12 drives second largest
Gear assembly 4.14 starts to rotate backward 90 °, and the second largest gear assembly 4.4 drives valve plate intercommunicating pore 4.29 by mandrel 4.25
Rotation；Valve disk is in the closed position at this time, the final opening and closing for controlling valve disk intercommunicating pore；
When the cam of the first canine tooth wheel assembly 4.12 triggers the second microswitch 4.13, the second microswitch 4.13 feedback
For signal to flushing controller 2, flushing controller 2 adjusts rotating and reverse for brushless motor 4.15 by feedback signal, and judges
Whether the time that valve disk intercommunicating pore 4.29 opens and closes is more than design value, and fault-signal will be exported when more than design value；
The second largest gear assembly 4.14 drives valve disc core axis 4.25 to rotate；
The second largest gear assembly 4.14 connects valve plate 4.23 by valve disc core axis 4.25, and then drives valve plate 4.23
Rotation.
In step 3, as shown in fig. 6, closestool drain valve 4 is blocked and cannot close when the energization of closestool drain valve 4 does not work
It closes, flushing controller 2 perceives blocked state by the detection time of the first microswitch 4.11 and the second microswitch 4.13；
After first time in flush cycle rinses failure, flushing controller 2 exports fault-signal, is at trouble lamp
Light state；
Press flushing controller 2 on maintenance button, open closestool drain valve 4, by waste water be discharged into waste water tank 10 (such as Fig. 1,
Shown in Fig. 2, Fig. 3)；
The shutdown of valve 5.5 closestool drain valve 4 (as shown in Figure 2 and Figure 3) is manually switched off by manually pulling out, debugging；It realizes
The function of product；
After troubleshooting, flushing process completes a circulation, and barrier is reported therefore signal lamp is in OFF state.
