The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Toilet system as shown in Figure 1, comprise one or more closets 20 that link to each other with vacuum tank 10, the pipeline that closet 20 links to each other with vacuum tank 10 is provided with blowoff valve 30, on the pipeline between blowoff valve 30 and the vacuum tank 10, also be respectively equipped with ball valve 70, vacuum tank 10 links to each other with vacuum pump 11, pipeline between closet 20 and the vacuum pump 11 is a vacuum state, is provided with pressure switch 12 between vacuum pump 11 and the vacuum tank 10.
As preferred version of the present utility model, selection is located at the outlet of the pipeline between one or more closets 20 and the vacuum tank 10 on the top of vacuum tank 10, vacuum tank 10 bottoms are provided with outlet near a jar bottom and link to each other with vacuum pump 11, and setting more helps the discharge of dirt like this.
As preferred version of the present utility model, vacuums in the vacuum tank 10 select to be arranged on-45KPa~-35KPa between, the force value of pressure switch 12 is identical with it, also be arranged on-45KPa~-35KPa between, filth-discharging effect between this regional value is best, as preferred scheme, select to be arranged on-this value of 40KPa is even more ideal.The force value of the vacuum of vacuum tank 10 and pressure switch 12 can make a change according to different situations, promptly can be provided with this value range lowlyer again or higher again, can realize the utility model purpose equally.
The water inlet of one or more closets 20 links to each other with waterworks, described waterworks are Automatic Water System, side at one or more closets 20 is provided with infrared sensing switch 80, waterworks comprise pressure water pump 40, the delivery port of pressure water pump 40 links to each other with the water inlet of one or more closets 20, is respectively equipped with the electromagnetic valve 60 of flushing the toilet between the water inlet of the delivery port of pressure water pump 40 and one or more closet 20; The water inlet of pressure water pump 40 is provided with clear water tanks 41, is provided with water purification level sensor 42 in the clear water tanks 41, is provided with strainer 43 between clear water tanks 41 and the pressure water pump 40.
As preferred version, the side that is chosen in closet 20 is provided with infrared sensing switch 80 and realizes monitoring, thereby reaches the function of automatic water supplement and blowdown, also can adopt artificial method to achieve this end.
The exit of vacuum pump 11 is connected with foul water tank 50, be provided with wastewater level sensor 51 in the foul water tank 50, the exit of foul water tank 50 is provided with sewage water discharge valve 52, described sewage water discharge valve 52 is by source of the gas 53 controls, be provided with blowdown electromagnetic valve 54 between source of the gas 53 and the sewage water discharge valve 52, the outlet of vacuum pump 11 is positioned at the top of foul water tank 50.
Vacuum pump 11, infrared sensing switch 80, the electromagnetic valve 60 of flushing the toilet, blowoff valve 30, pressure water pump 40, blowdown electromagnetic valve 54, water purification level sensor 42, wastewater level sensor 51 respectively with control circuit board 90 for being electrically connected.
The water route order of connection of native system is: the clear water tanks 41-strainer 43-pressure water pump 40-electromagnetic valve 60-closet 20-blowoff valve 30-vacuum tank 10-vacuum pump 11-foul water tank 50-sewage water discharge valve 52-emptying of flushing the toilet.
The gas circuit order of connection of native system is: source of the gas 53-blowdown electromagnetic valve 54-sewage water discharge valve 52.
The circuit order of connection of native system is: power supply 100-control circuit board 90 is connected to infrared sensing switch 80 respectively, the electromagnetic valve 60 of flushing the toilet, blowoff valve 30, pressure water pump 40, blowdown electromagnetic valve 54, water purification level sensor 42, wastewater level sensor 51 then.
Native system can specifically be applied to mobile washroom (the movably washroom that is provided with as park, commercial area, railway terminal and other places) or fixedly in washroom (as the washroom on ground such as hospital, barracks), existing is that example illustrates the concrete course of work with mobile washroom:
After clear water tanks 41 topped up with water and energising, vacuum pump 11 is started working, be vacuum tank 10 degree of being evacuated-vacuum of 40KPa after, pressure switch 12 is closed, vacuum pump quits work, simultaneously pressure water pump 40 is started working, and the hydraulic pressure in the toilet flushing tube (being the pipeline between each closet 20 of being exported to of pressure water pump 40) is brought up to 0.3-0.4MPa.When leaving after the people uses the washroom, infrared sensing switch 80 actions issue a signal to control circuit board 90, and control circuit board 90 sends signal and opens the electromagnetic valve 60 of flushing the toilet, owing in the toilet flushing tube hydraulic pressure is arranged, closet 20 begins flushing, pressure water pump 40 automatic ftercompctions; Control circuit board 90 also sends signal and opens blowoff valve 30 simultaneously, because the blow-off pipe that connects with vacuum tank 10 (being the pipeline between the vacuum tank 10 of being exported to of closet 20) interior vacuum is the same is-vacuum of 40KPa, the dirt in the closet 20 is inhaled into blow-off pipe to vacuum tank 10; When the vacuum in the vacuum tank 10 be lower than-during 40KPa, vacuum pump 11 starts once more, simultaneously the dirt in the vacuum tank 10 is entered foul water tank 50 storages.Foul water tank is during 50 approaching expiring after the so many person-time of use, and wastewater level sensor 51 sends alarm signal to control circuit board 90, and the washroom need move to blowdown place emptying foul water tank 50; If clear water tanks 41 is when empty, water purification level sensor 42 send alarm signal with to control circuit board 90, at this moment the washroom need move to suitable place and adds water for clear water tanks 41.
As preferred version, can also send alarm signal in the control circuit board at wastewater level sensor 51 and water purification level sensor 42, an external audible-visual annunciator can be known the water level situation so more convenient, intuitively.
