Description
Technical field
The utility model relates to a kind of improved negative pressure lavatory, belongs to can control the fecaluria foul smell not to external diffusion and obtain the water-saving negative pressure lavatory of high concentration night soil.
Background technology
The city of China extensively is faced with water and pollutes and the water resources crisis problem, and by 50 liters/day of everyone flushing supplies, Chinese Urbanization's rate 30%, National urban population is only flushed the toilet one with regard to about 0.05 * 365 * 1400000000 * 0.3=7665000000m of water consumption every year
3, promptly about 77 billion cubic meters.In addition, pollution load major part in the sanitary sewage is from night soil, and the total amount of night soil only accounts for about 1% of sanitary sewage total amount, if so night soil is collected separately under the situation of few dilution as far as possible by water-saving toilet, then can realize handling efficiently and utilizing, simplify simultaneously treatment process in a large number, more effectively utilize regenerated resources thereby reach to other sanitary sewage.Domestic also have many inventors to study water-saving toilet bowl, utilizes the time-delay inlet method as Chinese patent application 01107383.7, just realize large and small water supply volume separately respectively; Improve hydraulic pressure with the negative pressure water pipe, make to produce the water eddy-currents flushing that centrifugal force is arranged in the urinal, being used of multinomial technology can make the disposable total water amount of rinsing closet well at 2L or below the 2L, reaches the purpose of high-efficiency water-saving, but its structure is too complicated.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of novel water-saving negative pressure lavatory simple in structure is provided.This lavatory utilizes principle of negative pressure, and night soil is carried by the negative-pressure pipeline that links to each other with closet, and is minimum thereby the water of will flushing the toilet reduces to, and the valve on the negative-pressure pipeline is by the positive pressure-controlled of tap water in the waterpipe of flushing the toilet, and compact conformation is easy to use.
The utility model has adopted the design scheme that night soil is carried by the negative-pressure pipeline that links to each other with closet, its design feature is to comprise closet, flushing system, flushing system connects the bath water storage device, this device comprises the water pipe of flushing the toilet, jet water spout, flushing valve, valve cavity and the running water pipe that connects by water successively, the valve cavity bottom is an elastomeric material, and inside is provided with spring; Closet excrement outlet place is provided with negative pressure device, and this device comprises the negative pressure pipe, and negative pressure Guan Yiduan links to each other with the fecaluria outlet of closet bottom, and the other end links to each other with negative pressure source.Valve cavity bottom (elastomeric material) is pressed in the negative pressure inside pipe wall under the water action of gravity in the chamber.Also water storage cavity can be set between jet water spout, the outlet of water storage cavity and jet water spout inserts the water pipe of flushing the toilet.
The utility model is compared with prior art:
The utility model adopts the structure design that night soil is carried by the negative-pressure pipeline that links to each other with closet, by negative pressure ight soil is inhaled down, ight soil is discharged, with a spot of water closet is rinsed well again, reach good water-saving result, each discharging quantity of water is less than 1 liter, and each 5 liters of meters of flushing the toilet routinely can be saved 80% water supply volume; Collect the high concentration fecaluria simultaneously, be convenient to handle and utilization.
Description of drawings
Embodiment of the present utility model is shown among the figure:
Fig. 1 is the embodiment schematic diagram, 1. negative pressure pipes, 2. negative pressure pipes, 3. valve cavities, 4. water inlets, 5. delivery ports, 6. flushing valves, 7. water storage cavities, 8. jet water spouts, 9. springs, 10. elastomeric materials 11. water pipe 13. closets 14. flushing systems 15. running water pipes of flushing the toilet among the figure
Specific embodiments
In conjunction with the embodiments the utility model Water-saving negative pressure closet is described in further detail:
Accompanying drawing 1 has schematically shown the structure of this Water-saving negative pressure closet, comprises closet 13, on the flushing system 14 at closet 13 rear portions, connects the bath water storage device; Excrement outlet in closet 13 bottoms connects negative pressure device.
The bath water storage device comprises the water pipe 11 of flushing the toilet, jet water spout 8, flushing valve 6, valve cavity 3 and running water pipe 15, connects by water successively.The former flushing system 14 of flushing the toilet in water pipe 11 and the closet 13 is connected.The bottom of valve cavity 3 is an elastomeric material 10, connects spring 9 on this elastomeric material 10, and the other end of spring 9 is fixed on the top of valve cavity 3.8 of jet water spouts water storage cavity 7 is set, water storage cavity 7 inserts the water pipe 11 of flushing the toilet with the outlet of jet water spout 8.
Enter water inlet 4 diameters of valve cavity 3 from running water pipe 15, less than delivery port 5 diameters that enter jet water spout 8 from valve cavity 3.
Negative pressure device comprises the negative pressure pipe, and negative pressure Guan Yiduan is connected with the fecaluria outlet of closet 13 bottoms, and the other end is connected with negative pressure source; The elastomeric material 10 of valve cavity 3 bottoms is depressed into the negative pressure inside pipe wall by spring 9, and the negative pressure pipe is divided into negative pressure pipe 1 and negative pressure pipe 2 two parts, and the object (ight soil) that cuts off between negative pressure pipe 1 and the negative pressure pipe 2 flows.
Its operating principle: the negative pressure in the negative pressure pipe is supplied with by negative pressure source, and negative pressure is P1 (being generally-0.5 crust～-0.65 crust).There is malleation P2 (〉=1.5 crust) in running water pipe 15.When flushing valve 6 is in closed condition, be tap water in the negative pressure valve chamber 3, action of gravity pushing elastomeric material 10 is to the inwall of negative pressure pipe 1,2, and the object that cuts off negative pressure pipe 1 and 2 flows.
During work, open flushing valve 6, because the effect of spring 9, and the cross section of delivery port 5 is much larger than the cross section of water inlet 4, water in the valve cavity 3 flows out along the direction of delivery port 5, elastomeric material 10 space occurs with negative pressure pipe 1,2 inwalls, and negative pressure pipe 1 and 2 is connected, and the fecaluria and the water of partly flushing the toilet are walked by negative pressure transportation.At this moment, the water pipe 11 of flushing the toilet begins that water is arranged, and flows in the lavatory, and the cross section of the water pipe 11 of flushing the toilet is less than the cross section of jet water spout 8, and the tap water in the valve cavity 3 flows into its middle water storage cavity 7 by jet water spout 8 parts.After closing flushing valve 6, because the tap water that water inlet 4 is come in replenishes valve cavity 3, negative pressure pipe 1 and 2 is disconnected by the effect of elastomeric material again, water in jet water spout 8 and the middle water storage cavity 7 continues to flow to by the water pipe 11 of flushing the toilet the flushing system of urinal with action of gravity, with a spot of water closet 13 is cleaned on every side, thereby finish overall process.
