SB1 is spring-return switch, i.e. the operation button of equipment;KT6 is the normally closed switch of time of fire alarming relay control, It is disconnected when time of fire alarming relay power, i.e., KA2 can not be closed equipment and cannot run under alarm condition.SB1 button is pressed, it is intermediate Relay KA2 power-on switch KA2 closure, equipment start to rinse operation.Time relay KT1 starts timing, intermediate relay KM1 Power-on switch KM1 is closed air pump pressurization bath, and the normally closed delay disconnection switch of KT1 disconnects KM1 power-off air pump and stops pressurizeing after 15 seconds, The normally opened timing closing of KT1 closes the switch, and time relay KT2, which is powered, starts timing, equipment blowdown.KT2 is normally opened after 3.79 seconds prolongs When closure switch be closed, time relay KT3 be powered start timing, intermediate relay KM2 power-on switch KM2 be closed air pump pressurization It carries out second to wash by water, the normally closed delay of KT3 disconnects switch and disconnects after 7 seconds, and KM2 powers off air pump and stops pressurization, and the normally opened delay of KT3 is closed Combination switch closure, time relay KT4, which is powered, starts timing, equipment blowdown.The normally opened timing closing of KT4 closes the switch after 5 seconds, when Between relay KT5 be powered start timing, intermediate relay KM3 power-on switch KM3 be closed air pump pressurization bath, KT5 is normally closed after 2 seconds Delay disconnects switch disconnection KM3 power-off air pump and stops pressurization, and the normally opened timing closing of KT5 closes the switch, and intermediate relay KA2 is short Road, switch KA2 are disconnected, and all time relays automatically reset, and once flushing operation is completed.
Be illustrated in figure 8 time relay back panel wiring Fig. 2,7 be power interface, and 1,8 is common wire, 3,4 for 1 it is normally opened Normally closed interface, 5,6 be 8 normally closed normally opened interface.
The working principle of the invention is: urinal is connected to the lower section of nursing bed bed body, and urinal is aligned on nursing bed just hole Position.When flushing, start button is pressed, rear equipment is powered on and carries out self-test, indicator light is by red greening, table if all going well Bright equipment can operate normally;It is very few if water volume in water tank or corresponding alarm lamp is bright if dirt storage box reserves excessively reach alert locations Buzzer warning simultaneously.It works in alarm condition alarm relay, control normally opened relay switch cannot be closed, that is, be released Equipment cannot be run before alarming.
Operation button is pressed under equipment normal condition, 5 time relays successively work by the timing set, Ren Yishi Between relay work when normally opened relay switch be all closed.First time relay operating time 15S, when work first it is true Slack tank closes the switch the bath of vacuum pump pressurised water tank to urinal;Bath completes second time relay and starts to work, when Urinal filth is sucked dirt storage box by long 3.79S, vacuum pump decompression;Then the third time relay is started to work, duration 7S, second vacuum tank closes the switch the bath of vacuum pump pressurised water tank to urinal at this time;4th time after the completion of bath Relay is started to work, duration 5S, and urinal filth is sucked dirt storage box by vacuum pump decompression;Then the 5th time relay It starts to work, duration 2S, third vacuum tank closes the switch air pump pressurised water tank and goes out a small amount of water to urinal, flushing process knot at this time Beam.
Embodiment 2
Step 1 a kind of control method of bed body vacuum cleaner powers on rear equipment and carries out self-test, vacuum pump is by vacuum Air empties in tank, and vacuum pressure from red light becomes green light after reaching, and indicator light shows equipment by red greening if all going well It can operate normally;It is very few if water volume in water tank or corresponding alarm lamp is bright if dirt storage box reserves excessively reach alert locations while bee The device that rings is alarmed;Step 2, operation button is pressed under equipment normal condition, 5 time relays are by the timing set successively work Make, normally opened relay switch is all closed when any time relay works;First time relay work, control water pump are taken out Water is formed and is rinsed, and bedpan the inside is allowed to start water storage to certain altitude;Second time relay work, vacuum tank are opened, pipeline Interior formation vacuum, while the solenoid valve opening of bedpan discharges water;;Then the third time relay is started to work, the 2nd vacuum tank The bath of air pump pressurised water tank is closed the switch to urinal;The 4th time relay is started to work after the completion of bath, vacuum pump Urinal filth is sucked dirt storage box by decompression;Then the 5th time relay is started to work, and the 3rd vacuum tank closes the switch at this time Air pump pressurised water tank goes out a small amount of water to urinal, and flushing process terminates.
It in step 1, works in alarm condition alarm relay, control normally opened relay switch cannot be closed, that is, be solved Except alarming, preceding equipment cannot be run.
In step 2, first time relay operating time 15S, after the completion of bath, when second time relay works Long 3.79S, third time relay operating time 7S, the 4th time relay operating time 5S, the 5th time relay Device operating time 2S.
Finally, it should be noted that above embodiments are only to illustrate the present invention and not limit technology described in the invention Scheme;Therefore, although this specification is referring to above-mentioned each embodiment, the present invention has been described in detail, this Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent replacement;And all do not depart from this The technical solution and its improvement of the spirit and scope of invention, should all cover within the scope of the claims of the present invention.
