Abstract
The invention discloses a water-saving closestool, which is characterized in that a sewage system comprises a pan, a sewer pipe and a one-way valve, wherein a negative pressure device is arranged on the sewer pipe, and a driving device is arranged on the negative pressure device; the driving device comprises a piston cylinder and a control valve, and the control valve is connected with the piston cylinder through a hydraulic pipe; the control valve is a two-position four-way valve, and the interfaces of the two-position four-way valve are a drain outlet, a hydraulic control water valve connecting port, a piston cylinder connecting port and a water inlet which are sequentially arranged from top to bottom. With the technical scheme, the negative pressure device is started up when flushing water, so that the negative pressure is formed in the sewer pipe, liquid dung in the pan flows into the sewer pipe and opens the one-way valve to be discharged under the action of atmospheric pressure, and the pan can be cleaned by a small amount of fresh water; and the closestool can save about half of the amount of water compared with the closestool with the traditional structure.
Description
Technical field:
The present invention relates to a kind of water-saving toilet.
Background technology:
Sitting type toilet seat on the market advances the indoor pollution air in order to prevent the excrement air-flow, toilet just coil and sewer pipe between be connected with bend pipe, under the normality, all can contain water in the bend pipe, intercept excrement gas in the toilet tube flowed into chamber with this, when people's flushing the toilet after use, overcome the obstruction of bend pipe by thoroughly emptying in order to make ight soil, must pour a large amount of fresh waters toward just coiling, it is serious to cause wasting water.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, a kind of very water-saving toilet is provided.
For achieving the above object, technical scheme provided by the invention is: a kind of water-saving toilet, and its drainage includes just and in dish, sewer pipe, the sewer pipe one way valve is set, and sewer pipe connects negtive-pressure implement, and negtive-pressure implement is connected with the device that drives the negtive-pressure implement operation.
Described drive unit is made of piston rod that has reset function and control valve, the fixedlying connected of piston rod with negtive-pressure implement, and control valve is connected with piston rod by fluid pressure line.
Described control valve is the two-position four-way control valve, and the outfall of this two-position four-way control valve is connected with storage tank, and wherein two interfaces are connected with hydraulic control flushing valve piston rod respectively, and water inlet is connected with running water pipe.
After adopting technique scheme, bath starts negtive-pressure implement simultaneously, make and form negative pressure in the sewer pipe, liquid dung in the bedpan flows into sewer pipe and washes one way valve open and discharge under atmospheric effect, pour a small amount of fresh water and just can rinse bedpan, approximately can save the water supply volume of half than the toilet of traditional structure.
Description of drawings:
Accompanying drawing is the sectional structure chart of water-saving toilet of the present invention;
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
Present embodiment is a kind of water-saving toilet with water tank, include and just coil 1, sewer pipe 2 and storage tank 3, sewer pipe 2 upper ends and bedpan are right after, lower end and ground sewage draining exit are right after, sewer pipe middle part go out that an interface is right after with negtive-pressure implement and with one of the cavity held communicate, the lower end is provided with an one way valve 13 in the sewer pipe, and the middle part of sewer pipe has just formed the space of a sealing like this, and water tank 3 is connected with bedpan 1 by hydraulic control flushing valve 4.Button 7 on the tank lid connects two-position four-way control valve 8, and this control valve is a closed type, and the interface of two-position four-way control valve 8 is connected with water tank 3, hydraulic control flushing valve 4, piston rod 11 and running water pipe from top to bottom successively.
During normality, under back-moving spring in back-moving spring in button 7 and the two-position four-way control valve 8 acts on simultaneously, two-position four-way control valve 8 is in closed condition, be exactly that oral siphon 10 is closed in detail, same hydraulic control flushing valve 4 also is in closed condition under the action of reset spring of portion within it, the piston of piston rod 11 and negtive-pressure implement 12 all is in the next under the contained spring effect, and one way valve 13 also is in closed condition in the effect of gravity.During bath, press the button 7, piston rod in the two-position four-way control valve 8 moves downward, this process oral siphon 10 is communicated with hydraulic control flushing valve 4, piston rod 11, press water enters the pressure chamber of hydraulic control flushing valve 4 and piston rod 5, and the delivery port 6 that is communicated with storage tank 3 is closed, under the effect of hydraulic pressure, hydraulic control flushing valve 4 is opened, and fresh water flows to through one way valve 4 and just coils 1 flushing; The piston pressurized of piston rod 11 also drives negtive-pressure implement when up moving piston up moves, make the interior gas of confined space of sewer pipe 2 be drawn into negtive-pressure implement and form negative pressure state, 1 liquid dung enters in the sewer pipe 2 lower end and forms siphon in the bedpan under the effect of atmospheric pressure, wash one way valve 13 open again under inertia and gravity double action and pour sewers, and then one way valve 13 closes again.Release button 7 then, piston rod in the two-position four-way control valve 8 resets, oral siphon 10 is closed, delivery ports 6 in hydraulic control flushing valve 4, piston rod 11 and the two-position four-way control valve 8 are communicated with, and hydraulic control flushing valve 4 and piston rod 5 reset under the effect of back-moving spring separately, and the water of inside is separately pushed back in the two-position four-way control valve, again in delivery port 6 flows to storage tank 3, use prior art or water spare, water tank and bedpan are carried out moisturizing, make toilet return original state.Can be in this example by increasing some adjusting measures, the switching sequence of adjustment hydraulic control flushing valve 4 and piston rod 5 and time also can be changed the structure of control valve 8 to reach optimum efficiency, to adapt to existing ripe water spare, no longer statement here.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
