(3) utility model content
The utility model provides a kind of negative pressure closet and control device thereof, solve that existing device volume is too big, complex structure, stop up easily, noise is higher, water consumption is more, inconvenient problem with use.
The utility model negative pressure closet and control device thereof comprise urinal and bath control button, it is characterized in that:
Near the inwall upper edge a built-in water cavity of annular is arranged in urinal the inside, this built-in water cavity is distributed with at least two nozzles that communicate with the urinal inwall, and this built-in water cavity is communicated with connection barrier film water valve on this pipeline of washing by water with bath pipeline outside the urinal rear;
Rear at the bottom of the urinal pond is an outlet of sewer, outlet of sewer be inverted U-shaped noise reduction bend pipe and be communicated with, this noise reduction winding pipe exit connects negative-pressure pipeline, connects the barrier film sewage valve on this negative-pressure pipeline, connects negative one-way valve on the negative pressure acquisition port of negative-pressure pipeline;
The air inlet port of barrier film water valve be linked in sequence negative pressure clear water choke valve and negative pressure clear water one way valve, the air inlet port of barrier film sewage valve be linked in sequence negative pressure sewage choke valve and negative pressure sewage one way valve;
Connect the Comprehensive Control valve between two negative one-way valves that connect barrier film water valve and barrier film sewage valve, its Comprehensive Control valve top connects the bath control button.
Above-mentioned urinal is sitting toilet or squat type closet.
The built-in water cavity and the urinal of above-mentioned urinal are to be connected as a single entity.
The built-in water cavity of above-mentioned urinal be distributed with four with urinal in the nozzle that communicates.
The utility model compared with prior art has following beneficial effect:
1, simple in structure, easy to use, promptly the people only needs to push the button after with the lavatory, and negative pressure closet and control device thereof are automatically finished flushing and suction, and be last, residual a certain amount of reserved water in the closet.
2, compact conformation, volume is little, is easy to install.
3, controlling noise, noise reduction folding pipe is an inverted-loop tube in closet exit, directly links to each other with the barrier film sewage valve, by the noise reduction of this noise reduction folding pipe, negative pressure suction noise is reduced to below the 60dB.
4, water consumption is low, and water-saving result is obvious, and the each water consumption of the utility model is below 0.8 liter, and each water consumption is about 0.6 liter.
5, ight soil is collected separately, will stop the diffusion of pathogen.
6, the collection of high concentration fecaluria, realized the original-source by classification of sanitary sewage and human fecaluria, for subsequent treatment and comprehensive utilization provide may.
(4) description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1-negative one-way valve, 2-barrier film sewage valve, 3-negative pressure sewage choke valve, 4-negative pressure sewage one way valve, 5-Comprehensive Control valve, 6-flush button, 7-negative pressure clear water one way valve, 8-negative pressure clear water choke valve, 9-barrier film water valve, 10-noise reduction folding pipe, 11-nozzle, the built-in water cavity of 12-, 13-urinal, 14-negative pressure acquisition port, 15-urinal export, 16-washes by water pipeline.
(5) specific embodiment
Embodiment one is referring to Fig. 1, and urinal 13 is sitting toilets.Built-in water cavity is at the annular chamber of closet top loop around urinal, and is integrated with urinal.Built-in water cavity 12 is at the annular chamber of urinal 13 top loop around urinal, communicates with four nozzles 11 in urinal, connects bath pipeline 16 by barrier film water valve 9 outside urinal.Noise reduction folding pipe 10 is and urinal outlet 15 inverted-loop tubes that are connected, directly links to each other with barrier film sewage valve 2; The air inlet port of barrier film water valve 9 be linked in sequence negative pressure clear water choke valve 8 and negative pressure clear water one way valve 7, the air inlet port of barrier film sewage valve 2 be linked in sequence negative pressure sewage choke valve 3 and negative pressure sewage one way valve 4; Regulate the delay time that the size of above-mentioned negative pressure sewage choke valve and negative pressure clear water choke valve restriction can control valve be closed; Negative pressure acquisition port 14 on the negative-pressure pipeline is connected with negative one-way valve 1, and the effect of negative one-way valve is negative pressure can only to be advanced can not go out; Comprehensive Control valve 5 is controllers of opening barrier film water valve 9 and barrier film sewage valve 2, guarantee to be not less than-negative pressure of 0.3ba enters the control chamber of barrier film water valve and barrier film sewage valve, and the flush button 6 on Comprehensive Control valve top is the control starter.
Embodiment two: its urinal can be a squat type closet.
The operating principle of negative pressure closet of the present utility model and control device thereof is as described below:
During normality, the Comprehensive Control valve is in closed condition, interrupts in Comprehensive Control valve 5 through negative one-way valve 1 from the negative pressure of the negative pressure acquisition port 14 of controlling usefulness.At this moment, the control chamber of barrier film water valve 9 and barrier film sewage valve 2 communicates with atmosphere by negative pressure clear water choke valve 8 and negative pressure sewage choke valve 3 respectively, and the barrier film of two valves makes valve be in closed condition under the precommpression of spring.When pressing the button 6, Comprehensive Control valve 5 judges whether the negative pressure from negative pressure acquisition port 14 is higher than-0.3ba.If the negative pressure from negative pressure acquisition port 14 is higher than-0.3ba, negative pressure just directly enters the control chamber of barrier film sewage valve 2 and barrier film water valve 9 respectively through negative pressure sewage one way valve 4 and negative pressure clear water one way valve 7, barrier film sewage valve 2 and barrier film water valve 9 are opened, tap water enters built-in water cavity 12 by four nozzle 11 flushing toilet bowls, negative pressure enters urinal through noise reduction folding pipe 10 simultaneously, a spot of flushing water and fecaluria are pumped to the negative pressure line system, simultaneously, atmosphere enters the control chamber of barrier film water valve 9 and barrier film sewage valve 2 respectively slowly through negative pressure clear water choke valve 8 and negative pressure sewage choke valve 3, so that close two valves, can set up the size of the restriction of two choke valves in advance, barrier film sewage valve 2 is closed prior to barrier film water valve 9, and guaranteeing has a certain amount of residual water at last in urinal 13.
The mode of Comprehensive Control valve 5 control negative pressure is: when negative pressure be higher than-during 0.3ba, by; When negative pressure be lower than-during 0.3ba, the Comprehensive Control valve can be remembered enabling signal, up to negative pressure be higher than-0.3ba just makes negative pressure pass through.
