Description

Technical Field

[0001] The present application relates to the technical field of household sanitary ware, and particularly relates to a water-saving toilet with separate channels for discharging urine and feces. Background Art

[0002] Toilets are common household sanitary wares in daily life. In existing toilets, a float-type or float-box type water inlet valve is installed in the water tank to control the water inlet level, and an adjustment mechanism is provided on the drain valve to adjust the amount of water discharged. This structure has the following defects: 1. When the drain valve is not divided into a large-discharge and a small-discharge structure, the amount of water discharged is fixed after the adjustment mechanism is adjusted. This means that the minimum amount of water discharged must meet the requirement for flushing feces, that is, the same amount of water used for flushing feces must also be used for flushing urine, resulting in waste. 2. When the drain valve is divided into a large-discharge and a small-discharge structure, the amount of water discharged is no longer controlled by the adjustment mechanism, but instead, different control buttons are pressed for the drain outlet of the large-discharge structure and the drain outlet of the small-discharge structure to perform large-discharge or small-discharge. Although this structure reduces water waste to a certain extent, since the sewage all flows out through the same sewage bend, and the sewage bend is an S-shaped bend, a certain amount of water needs to flow in before a siphon effect can be formed, and finally the water flow and excrement in the sewage bend are pumped into the sewage pipe and discharged. That is to say, the structure of the single-sewage-channel toilet in the prior art itself already limits the minimum flushing water volume, and no matter how the drain valve in the water tank is changed, a certain degree of waste will be caused.

[0003] To solve the above technical problems, in the prior art, there has appeared a toilet in which the toilet base is divided into a urinal at the front side and a toilet bowl at the rear side by a partition, and different sewage pipes are connected to the bottoms of the urinal and the toilet bowl to achieve the purpose of water saving for urine. However, it has the disadvantages of being difficult to clean, bacteria being easily bred on the partition, being easily touched by the private parts of the human body, and being prone to disease transmission.

[0025] This application is not limited by the following embodiments, and the specific implementation manners can be determined according to the technical solutions of this application and the actual situation.

[0026] In this application, for the convenience of description, the description of the relative position relationship of each component is carried out according to the layout mode of the attached Figure 1 drawings of the specification. For example, the position relationships such as up, down, left, and right are determined according to the layout direction of the attached Figure 1 drawings of the specification.

[0027] The following further describes this application in combination with the embodiments and the drawings. Embodiment 1: As shown in the attached Figures 1 to 2 drawings, the water-saving toilet with separate channels for discharging urine and feces includes a toilet body. A downwardly concave bucket seat 1 is provided on the front side of the toilet body, and a water storage tank 4 for storing water is provided on the rear side of the toilet body;

[0028] A sewage outlet is provided at the lowest point of the barrel seat 1, and a sewage pipe 10 is connected below the sewage outlet. The rear end of the sewage pipe 10 is connected with a parallel main sewage pipe 10-1 and an auxiliary sewage pipe 10-3, thereby forming two sewage discharge channels; the sewage outlet of the auxiliary sewage pipe 10-3 is connected with the upper pipe wall of the sewage outlet of the main sewage pipe 10-1, and the sewage outlet of the main sewage pipe 10-1 is connected with the sewer pipe; a sewage discharge device 9 is provided at the sewage inlet of the auxiliary sewage pipe 10-3. If the sewage outlets of the main sewage pipe 10-1 and the auxiliary sewage pipe 10-3 are connected, the sewage discharge device 9 is used to control whether the auxiliary sewage pipe 10-3 is connected to the main sewage pipe 10-1; if the sewage outlets of the main sewage pipe 10-1 and the auxiliary sewage pipe 10-3 are not connected, the sewage discharge device 9 is used to control whether the auxiliary sewage pipe 10-3 discharges sewage.

[0029] A toilet flushing valve 5 connected to the main flushing pipe 7, a water-saving control device 6 connected to the auxiliary flushing pipe 8, and a urine flushing button 3 for controlling the opening and closing of the sewage discharge device 9 are arranged in the water tank 4; the drainage port of the main flushing pipe 7 is arranged on the inner wall of the bucket seat 1 above the aforementioned sewage discharge port, and the drainage port of the auxiliary flushing pipe 8 is arranged on the inner wall of the upper side of the sewage inlet of the main sewage discharge pipe 10-1. A plurality of flushing nozzles 2 connected in series or in parallel are arranged on the inner edge of the ring toilet body.

[0030] like Figure 1 , 2 As shown in Figure 3, a U-shaped water trap 10-2 is arranged between the auxiliary sewage pipe 10-3 and the main sewage pipe 10-1, and the sewage inlet of the water trap 10-2 is connected to the sewage outlet of the auxiliary sewage pipe 10-3, and the sewage outlet of the water trap 10-2 is connected to the upper side pipe wall of the sewage outlet of the main sewage pipe 10-1.

[0031] Furthermore, a transition pipe is connected between the auxiliary sewage pipe 10-3 and the water trap 10-2, the sewage inlet of the transition pipe is connected to the sewage outlet of the auxiliary sewage pipe 10-3, the sewage outlet of the transition pipe is connected to the sewage inlet of the water trap 10-2, and the sewage discharge device 9 is arranged in the transition pipe.

[0032] The sewage device 9 is used to control the conduction between the auxiliary sewage pipe 10-3 and the water trap 10-2, that is, to control the conduction between the auxiliary sewage pipe 10-3 and the main sewage pipe 10-1; the setting of the water trap 10-2 can form a water seal at the water trap 10-2 on the one hand to prevent the backflow of odor, and on the other hand, it makes the sewage discharge of urine no longer use the siphon principle, but use the liquid level difference in the U-shaped structure to discharge sewage, so that the flushing water volume of urine is reduced, thereby achieving the purpose of water saving.

[0033] like Figure 1 , 3As shown in FIGS. 5, the sewage discharge device 9 is a piston-sealing valve, including a piston tube 9-4 communicated with the transition pipeline. The piston tube 9-4 is a cavity tube with one end open and the other end closed. Inside the open end of the piston tube 9-4, that is, at the connection between the piston tube 9-4 and the transition pipeline, a piston seat 9-1 with a central opening is provided. Inside the piston tube 9-4, a piston rod 9-5 with its inner end fixedly connected to the piston 9-2 is arranged. The piston 9-2 matches and seals the sewage inlet of the transition pipeline with the piston seat 9-1. The outer end of the piston rod 9-5 extends out of the piston tube 9-4 from the closed end of the piston tube 9-4 and is sleeved on the fixed rod 9-12. The fixed rod 9-12 is fixed on the fixed seat 9-9. A return spring 9-10 is sleeved on the fixed rod 9-12 between the fixed seat 9-9 and the piston rod 9-5. An opening is formed on the tube wall of the piston tube 9-4 behind the piston seat 9-1, and this opening is communicated with the sewage inlet of the water seal bend 10-2.

[0034] Further, a slider 9-11 is fixed at the outer end of the piston rod 9-5. The slider 9-11 is sleeved on the fixed rod 9-12 and can slide back and forth along the fixed rod 9-12. The two ends of the aforementioned return spring 9-10 are respectively fixed on the opposite surfaces of the fixed seat 9-9 and the slider 9-11.

[0035] Further, a pressure rod 9-7 is connected below the urine flushing button 3. The pressure rod 9-7 is made of a light material, such as PVC, and can float in water. The lower end of the pressure rod 9-7 is hinged to the upper ends of the third connecting rod 9-6 and the fourth connecting rod 9-8. The lower end of the third connecting rod 9-6 is hinged to the closed end of the piston tube 9-4. The lower end of the fourth connecting rod 9-8 is hinged to the upper end of the slider 9-11.

[0036] When the urine flushing button 3 is pressed, the pressure rod 9-7 moves downward, causing the upper ends of the third connecting rod 9-6 and the fourth connecting rod 9-8 to move downward. Since the third connecting rod 9-6 is connected to the fixed piston tube 9-4, the fourth connecting rod 9-8 can only push the slider 9-11 to move outward, thereby driving the displacement of the piston 9-2, releasing the seal of the piston 9-2 at the piston seat 9-1, and exposing the opening, making the secondary sewage pipe 10-3 communicate with the water seal bend 10-2. At this time, the liquid level at the secondary sewage pipe 10-3 is higher than the liquid level of the water seal bend 10-2, and the sewage can flow into the main sewage pipe 10-1 through the water seal bend 10-2 and finally be discharged through the sewer pipe.

[0037] The pipeline behind the sewage inlet of the main sewage pipe 10-1 is in an inverted U shape. This structure forms an S-shaped bend with the sewage pipe 10, so as to form a water seal at the bottom of the sewage pipe 10 and the front section of the main sewage pipe 10-1. This structure uses the siphon principle to suck out the sewage at the water seal, which is the prior art.

[0038] Since there will be no substances in the urine that can block the sewage pipe 10, the urine can be discharged from the secondary sewage pipe 10-3 with a smaller diameter. This sewage discharge structure can use the minimum amount of water for flushing and sewage discharge. For feces that may block the sewage pipe 10, they can be discharged from the main sewage pipe 10-1 with a larger diameter and stronger suction force. Eventually, a method of separate-channel discharge of feces and urine is formed, thereby achieving the purpose of water conservation.

[0039] As Figure 7 , 8 , as shown in Figure 9, the water-saving control device includes a water inlet valve 6-5 and a water-saving control valve 6-4. The water inlet valve 6-5 includes a first water outlet pipe 6-14 for filling water into the water tank, and a second water outlet pipe 6-10 for supplying water to the flushing nozzle 2 along the upper edge of the bucket seat 1. A first plug rod 6-15 is inserted into the first valve body 6-17 where the first water outlet pipe 6-14 is located, and a second plug rod 6-9 is inserted into the second valve body 6-8 where the second water outlet pipe 6-10 is located. The upper ends of the first plug rod 6-15 and the second plug rod 6-9 are fixedly connected to a gland 6-6 arranged above the first valve body 6-17 and the second valve body 6-8. The upper end surface of the gland 6-6 is hinged to the lower end of the second connecting rod 6-2, and the upper end of the second connecting rod 6-2 is hinged to the upper end of the first connecting rod 6-1, and the hinged part is a fixed hinge point 6-7. The water-saving control valve 6-4 is used to supply water to the secondary flushing pipe 8, and it includes a water storage tank 6-25 with an internal water storage cavity. A floating cover 6-24 that floats up and down with the water level is arranged in the water storage cavity. The lower end of the aforementioned first connecting rod 6-1 extends into the water storage tank 6-25 and is hinged to the upper end surface of the floating cover 6-24. When the floating cover 6-24 floats up, that is, when the water storage tank 6-25 starts to store water, the floating cover 6-24 pushes the first connecting rod 6-1 to rotate around the hinge point 6-7, thereby driving the second connecting rod 6-2 to rotate downward and pushing the gland 6-6 to move downward.

[0040] The water inlet valve 6-5 further includes a third valve body 6-12 with a cavity. The cavity in the third valve body 6-12 is communicated with the water inlet pipe 11. Two water supply holes 6-13 that are respectively communicated with the interiors of the first valve body 6-17 and the second valve body 6-8 are arranged on the upper end surface of the third valve body 6-12. The lower ends of the first plug rod 6-15 and the second plug rod 6-9 can be inserted into the water supply holes 6-13 to form a blockage of the water supply holes 6-13. When the gland 6-6 moves downward under the influence of the floating cover 6-24, the first plug rod 6-15 and the second plug rod 6-9 are inserted downward into the water supply holes 6-13 to form a blockage of the water supply holes 6-13, and the first water outlet pipe 6-14 and the second water outlet pipe 6-10 stop discharging water.

[0041] The water-saving control valve 6-4 further includes a drain box 6-23 disposed in the water storage tank 6-25. The drain box 6-23 has an open upper end, and the aforementioned floating cover 6-24 seals the open upper end of the drain box 6-23. A secondary drain port 6-22 is formed at the bottom of the drain box 6-23. The secondary drain port 6-22 communicates with the secondary flushing pipe 8. A cover 6-21 is covered at the secondary drain port 6-22. One end of the cover 6-21 is hinged to the bottom of the drain box 6-23, and a pull rope 6-3 is tied to the other end. The pull rope 6-3 is linked with the pressing rod 9-7.

[0042] Further, an air inlet hole 6-19 is formed at the top of the water storage tank 6-25, and a water replenishing hole 6-20 is formed at the lower part of the side wall of the water storage tank 6-25. After the cover 6-21 is opened and the drain box 6-23 starts to drain water, the water in the water tank 4 enters the water storage tank 6-25 through the water replenishing hole 6-20. However, since the amount of replenished water is less than the amount of drained water, the floating cover 6-24 is in a descending state.

[0043] Further, a fixed pulley 6-18 is fixedly arranged in the water tank 4. The aforementioned pull rope 6-3 is wound around the fixed pulley 6-18 and then fixedly connected to the rod body of the aforementioned pressing rod 9-17. When the pressing rod 9-7 moves downward, the pull rope 6-3 is pulled, causing one end of the cover 6-21 to be lifted, exposing the secondary drain port 6-22. The water in the drain box 6-23 enters the secondary flushing pipe 8 to flush the sewage inlet of the main sewage pipe 10-1. At this time, the floating cover 6-23 moves downward as the water level drops, thereby driving the pressing cover 6-6 to move upward. The first plug rod 6-15 and the second plug rod 6-9 are disengaged from the water supply hole 6-13 upward, and the first water outlet pipe 6-14 and the second water outlet pipe 6-10 start to supply water. The flushing nozzle 2 flushes water simultaneously with the secondary flushing pipe 8 at this time.

[0044] The flushing process in Embodiment 1 of this application is as follows: Before urination, a certain amount of water remains in the urinal seat 1. After urination, the urinal flushing button 3 is pressed, and the pressing rod 9-7 moves downward, causing the upper ends of the third connecting rod 9-6 and the fourth connecting rod 9-8 to move downward. The fourth connecting rod 9-8 pushes the slider 9-11 to move outward, thereby driving the piston 9-2 to displace, releasing the seal of the piston 9-2 at the piston seat 9-1 and exposing the opening, so that the secondary sewage pipe 10-3 is communicated with the water seal bend 10-2. At this time, the liquid level at the secondary sewage pipe 10-3 is higher than the liquid level of the water seal bend 10-2, and urine can flow into the main sewage pipe 10-1 through the water seal bend 10-2 and is finally discharged through the sewer pipe.

[0045] Meanwhile, the downward movement of the pressure rod 9-7 pulls the pull rope 6-3, causing one end of the cover 6-21 to lift, exposing the secondary drain port 6-22. The water in the drain tank 6-23 enters the secondary flushing pipe 8 to flush the sewage inlet of the main sewage pipe 10-1. At this time, the floating cover 6-23 moves downward as the water level drops, and then drives the pressing cover 6-6 to move upward. The first plug rod 6-15 and the second plug rod 6-9 are disengaged from the water supply hole 6-13 upward, and the first water outlet pipe 6-14 and the second water outlet pipe 6-10 start to supply water. At this time, the flushing nozzle 2 and the secondary flushing pipe 8 flush simultaneously.

[0046] After pressing the urine flushing button 3 for a certain period of time and the urine has been discharged, the urine flushing button 3 can be released. At this time, the water in the water storage tank 6-25 has been basically discharged. At the same time, the pressure rod 9-7 floats under the influence of the water level in the water tank 4, and the cover 6-21 naturally seals the secondary drain port 6-22, causing the water level in the water storage tank 6-25 to gradually recover. As the floating cover 6-24 gradually floats while the water level recovers, when driving the pressing cover 6-6 to move downward, the first plug rod 6-15 and the second plug rod 6-9 are inserted downward into the water supply hole 6-13 to form a blockage of the water supply hole 6-13, and the first water outlet pipe 6-14 and the second water outlet pipe 6-10 stop discharging water. At the same time, under the action of the return spring 9-10, the piston 9-2 moves inward to seal the piston seat 9-4 and stop sewage discharge. During the process of finally stopping flushing and sewage discharge, a certain amount of water will remain in the sewage pipe 10 to form a water seal.

[0047] Embodiment 2: As Figure 2 、 4 shown in FIG. 6, a transition pipe is connected between the secondary sewage pipe 10-3 and the water seal bend 10-2. The sewage inlet of the transition pipe is connected to the sewage outlet of the secondary sewage pipe 10-3, and the sewage outlet of the transition pipe is connected to the sewage inlet of the water seal bend 10-2. The sewage discharge device 9 is arranged in the transition pipe. A front baffle 9-13 and a rear baffle 9-16 are respectively arranged at the sewage inlet and the sewage outlet of the transition pipe, and a closed space is formed in the transition pipe. The sewage discharge device 9 is a water pump 9-14, which is fixed in the transition pipe. The suction pipe 9-17 of the water pump 9-14 extends into the secondary sewage pipe 10-3 from the front baffle 9-13, and the drain pipe 9-15 of the water pump 9-14 extends into the water seal bend 10-2 from the rear baffle 9-16.

[0048] The water pump 9-14 is connected to the power supply and is connected to the touch switch circuit arranged at the urine flushing button 3 through a wire. When the urine flushing button 3 is pressed or bounced, the touch switch will be touched, thereby forming the start-stop control of the water pump 9-14. This control method is an existing technology and not the invention point of this application, so the circuit is not described in detail here.

[0049] In this embodiment, except for the sewage discharge device 9 and its start-stop control, the rest of the structure is the same as that of Embodiment 1. After the urinal flush button 3 is pressed, the flush nozzle 2 and the secondary flush pipe 8 will flush water. At this time, the water pump 9-14 is in the starting state, and urine will be pumped by the water pump 9-14 to the trap 10-2 and then enter the main sewage pipe 10-1 for final discharge. After the urinal flush button 3 is released, the water pump 9-14 stops working, and the flush nozzle 2 and the secondary flush pipe 8 stop flushing water.

[0050] Embodiment 3: A water-saving toilet with separate channels for discharging feces and urine includes a toilet body. A downwardly concave bucket seat 1 is provided on the front side of the toilet body, and a water tank 4 for storing water is provided on the rear side of the toilet body;

[0051] A sewage discharge port is provided at the lowest point of the bucket seat 1, and a sewage pipe 10 is connected below the sewage discharge port. The rear end of the sewage pipe 10 is connected to a parallel main sewage pipe 10-1 and a secondary sewage pipe 10-3, thus forming two sewage discharge channels; the sewage discharge port of the secondary sewage pipe 10-3 is not connected to the sewage discharge port of the main sewage pipe 10-1, and they are respectively connected to the sewage pipe; a sewage discharge device 9 is provided at the sewage inlet of the secondary sewage pipe 10-3. Since the sewage discharge ports of the main sewage pipe 10-1 and the secondary sewage pipe 10-3 are not connected, the sewage discharge device 9 is used to control whether the secondary sewage pipe 10-3 discharges sewage.

[0052] A feces flush valve 5 connected to the main flush pipe 7, a water-saving control device 6 connected to the secondary flush pipe 8, and a urinal flush button 3 for controlling the opening and closing of the sewage discharge device 9 are provided in the water tank 4; the drainage port of the main flush pipe 7 is provided on the inner wall of the bucket seat 1 above the sewage discharge port, and the drainage port of the secondary flush pipe 8 is provided on the inner wall above the sewage inlet of the main sewage pipe 10-1. A plurality of flush nozzles 2 are arranged in series or in parallel along the inner edge of the toilet body.

[0053] The usage method of this embodiment is the same as that of Embodiment 1, and the difference lies only in whether the sewage discharge ports of the main sewage pipe 10-1 and the secondary sewage pipe 10-3 are connected.

[0054] In Embodiment 1, Embodiment 2 and Embodiment 3 of the present application, the setting of the feces flush valve 5 and the main sewage pipe 10-1 is the same as the structure of the existing flush toilet, which is prior art. The feces flush valve 5 includes a toilet water inlet valve and a toilet water discharge valve, and its specific structure and principle are not the invention points of the present application and will not be described in detail. The present application actually adds a secondary sewage pipe 10-3, and a water-saving control device 6, a secondary flush pipe 8, and a sewage discharge device 9 that are matched with the secondary sewage pipe 10-3 on the basis of the structure of the existing ordinary toilet to finally form a separate sewage discharge for urine and achieve the purpose of water saving.

[0055] The above description is only an example for clearly explaining the present application, rather than a limitation on the implementation manners of the present application. Any obvious changes or variations derived from the technical solutions of the present application still fall within the protection scope of the present application.
