When the purified water chamber drains water, the second scraper scrapes the bottom surface of the inner wall of the sewage chamber to clean the inner wall of the sewage chamber, keeping the inside of the sewage chamber clean. The shape of the second scraper is set to be the same as the shape of the notch in the cross-section of the "匚"-shaped first scraper. When the purified water chamber drains water, the second scraper scrapes under the first scraper to clean the second scraper, keeping the sewage chamber clean. By setting through holes surrounding the edge of the second scraper, the water flow in the purified water chamber flushes the dirt scraped by the second scraper when pushing the second scraper, ensuring the cleanliness inside the sewage chamber. By setting a nozzle, the water flow speed is increased, making the flushing effect better. By setting a groove and misaligning the through hole with the inlet of the connecting pipe, sewage does not flow into the connecting pipe. By setting a water delivery air bag, sewage enters the sewage chamber conveniently. Brief Description of the Drawings

[0043] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0044] Example

[0045] Please see Figures 1-6The toilet with recyclable wastewater provided by this invention includes a toilet body 10, a water tank 20, and a drain pipe 30. The water tank 20 is installed on the toilet body 10, and one end of the drain pipe 30 is connected to the water tank 20, and the other end is connected to the toilet body 10. A partition 23 is provided inside the water tank 20, and the partition 23 is fixedly connected to the inner wall of the water tank 20, dividing the water tank 20 into two parts: the upper part of the water tank 20 is a clean water chamber 21, and the lower part is a wastewater chamber 22. The clean water chamber 21 is connected to a tap water pipe, and the wastewater chamber 22 is connected to a wastewater recycling structure 40, and the wastewater chamber 22 is located below the clean water chamber 21. The clean water chamber 21 and the wastewater chamber 22 are connected by a connecting structure 24. One end of the drain pipe 30 is connected to the wastewater chamber 22, and the other end is connected to the toilet body 10. When the toilet is flushed, the wastewater in the wastewater chamber 22 first flushes the toilet body 10. After flushing, a layer of dirt remains on the toilet's wash surface. After flushing the toilet with wastewater, water from the clean water chamber 21 flows through the connecting pipe 241 into the wastewater chamber 22 to flush the wastewater chamber 22. The water then flows into the drain pipe 30 to flush the toilet. Flushing the toilet with wastewater first saves water resources. Then, clean water flushes the wastewater chamber 22 and the toilet's wash surface, ensuring that the dirt on the wash surface of the toilet body 10 and the wastewater chamber 22 is thoroughly cleaned, preventing scale buildup on the wash surface and ensuring the cleanliness of the toilet's wastewater chamber 22 and wash surface.

[0046] Wastewater placed in the sewage chamber 22 generally originates from handwashing and vegetable washing sinks. Wastewater from handwashing or vegetable washing is generally not very dirty. Wastewater from bathing is generally not recycled. If bathing wastewater is recycled into the sewage chamber 22, it is easy to generate more dirt on the inner wall of the sewage chamber 22 and may produce an odor.

[0047] The connection structure 24 includes a connecting pipe 241 and a one-way valve 242. One end of the connecting pipe 241 is connected to the clean water chamber 21, and the other end is connected to the sewage chamber 22. The one-way valve 242 is located in the middle of the connecting pipe 241. The one-way valve 242 allows water in the clean water chamber 21 to flow smoothly from the connecting pipe 241 into the sewage chamber 22. When the sewage chamber 22 is filled with water, the one-way valve 242 prevents sewage from flowing back into the clean water chamber 21, thus avoiding contamination of the clean water chamber 21 by sewage.

[0048] In some cases, the elastic elements of the check valve 242, such as the spring 2423, are in long-term contact with the fluid inside the valve body 2421. However, in this invention, the sewage in the sewage chamber 22 is generated after washing hands or vegetables, and contains detergents or other inorganic salts, which can easily corrode the spring 2423 of the check valve 242, rendering the check valve 242 unusable. Therefore, this type of check valve 242 is not suitable for the water tank 20 disclosed in this invention.

[0049] Preferably, in one embodiment of the present invention, as Figure 13As shown, the valve core 2422 and the valve body 2421 form a cavity, and the spring 2423 is disposed in the cavity. When the valve core 2422 moves or is stationary, the spring 2423 does not directly contact the clean water or sewage, which extends the service life of the one-way valve 242.

[0050] Sewage continues to accumulate in the sewage chamber 22 for a long time, and simply rinsing with clean water cannot effectively remove the dirt inside.

[0051] Preferably, in one embodiment of the present invention, in order to ensure that the dirt in the sewage chamber 22 can be cleaned in a timely manner, the toilet further includes a first cleaning structure 25, which is installed in the sewage chamber 22 and is used to remove dirt from the inner wall of the sewage chamber 22.

[0052] The first cleaning structure 25 includes a first guide rod 251 and a first scraper 252. Both the first guide rod 251 and the second scraper 252 are disposed within the wastewater box. The first scraper 252 has a through hole, and the first guide rod 251 is inserted into the through hole and slidably connected to the first scraper 252. The first guide rod 251 is fixedly connected to the lower surface of the partition 23 and extends downwards. The edge of the first scraper 252 abuts against the side wall of the inner cavity of the wastewater box. When the first scraper 252 moves up and down along the first guide rod 251, the scraper 252 abutting against the wastewater box scrapes off dirt adhering to or deposited on the side wall of the wastewater box.

[0053] In this embodiment, the first scraper 252 is a float plate, which rises as the liquid level rises when water is injected into the sewage chamber 22. Simultaneously, the first scraper 252 carries a certain weight; when sewage is discharged from the sewage chamber 22, the weight of the first scraper 252 overcomes the friction of the dirt on the inner wall of the sewage chamber 22, causing the first scraper 252 to fall and scrape off the dirt from the inner wall of the sewage chamber 22.

[0054] Optionally, in one embodiment of the present invention, the cross-sectional shape of the first guide rod 251 may be a triangle, a quadrilateral, or a circle.

[0055] Preferably, in one embodiment of the present invention, the first guide rod 251 is a circular guide rod, which is easy to process, and the sliding hole on the first scraper 252 corresponding to the first guide rod 251 is easy to process.

[0056] To make the first scraper 252 more stable during its up-and-down movement, two first guide rods 251 are usually provided. The two first guide rods 251 are symmetrically distributed on both sides of the first scraper 252 so that the first scraper 252 remains horizontal during its descent.

[0057] Optionally, in one embodiment of the present invention, the lower part of the first scraper 252 may be a material with a density less than water, such as foam, while the upper part of the first scraper 252 is equipped with a load. When sewage is injected, the foam is driven by buoyancy to rise the first scraper 252, causing the first scraper 252 to abut against the lower surface of the partition 23.

[0058] Preferably, in one embodiment of the present invention, the side of the first scraper 252 and the inner wall of the sewage chamber 22 are tightly connected to prevent sewage from seeping into the upper surface 2521 of the first scraper and causing scale to form on the upper surface 2521 of the first scraper.

[0059] The first scraper 252 prevents the top and sides of the inner wall of the sewage chamber 22 from remaining clean, but scale will still accumulate on the bottom surface of the sewage chamber 22. Moreover, due to gravity settling, most of the dirt will accumulate on the bottom surface of the inner wall of the sewage chamber 22. At the same time, the dirt at the bottom of the first scraper 252 cannot be removed either.

[0060] Preferably, in one embodiment of the present invention, the toilet further includes a second cleaning structure 26. The second cleaning structure 26 is disposed in the sewage chamber 22 and is used to scrape off dirt from the bottom surface of the first scraper 252 and the bottom surface of the inner wall of the sewage chamber 22.

[0061] The second cleaning structure 26 includes a second guide rod 261 and a second scraper 262. Both the second guide rod 261 and the second scraper 262 are disposed within the sewage chamber 22. The second guide rod 261 is fixedly connected to the inner wall of the sewage chamber 22, and the extending direction of the second guide rod 261 is the same as the fluid flow direction within the sewage chamber 22. The second scraper 262 abuts against the bottom surface of the sewage chamber 22 and is slidably connected to the second guide rod 261.

[0062] The second scraper 262 is initially located beside the outlet of the connecting pipe 241. When the water in the clean water chamber 21 flows down and is discharged from the outlet of the connecting pipe 241, the second scraper 262 is pushed and slides along the second guide rod 261, thereby scraping off the dirt on the bottom surface of the sewage chamber 22.

[0063] If the connecting pipe 241 between the sewage chamber 22 and the one-way valve 242 is contaminated by sewage in the sewage chamber 22, scale will also form inside the connecting pipe 241. Similarly, scale will also form on the second scraper 262 under the contamination of sewage, and it cannot be removed. Furthermore, the dirt on the side of the second scraper 262 near the connecting pipe 241 will invade into the connecting pipe 241.

[0064] Preferably, in an embodiment of the present invention, in order to prevent the connecting pipe 241 from being contaminated by sewage, the inner wall of the sewage chamber 22 on one side of the connecting pipe 241 is recessed to form a groove 221 that matches the shape of the second scraper 262. When the second scraper 262 is in the initial position, it closely cooperates with the groove 221 to close the water inlet of the connecting pipe 241, so as to ensure that the connecting pipe 241 will not scale.

[0065] When the second scraper 262 moves to the end of the second guide rod 261, the second scraper 262 needs to be reset to the initial position to facilitate scraping the dirt on the bottom surface of the inner wall of the sewage chamber 22 again.

[0066] However, if the second scraper 262 is reset by the sewage entering when the sewage chamber 22 stores water, scaling will occur on the side of the second scraper 262 close to the connecting pipe 241. Therefore, the second scraper 262 cannot be reset by sewage.

[0067] Preferably, in an embodiment of the present invention, the toilet further includes an elastic member. One end of the elastic member is fixedly connected to the inner wall of the sewage chamber 22 in the groove 221, and the other end is fixedly connected to the second scraper 262. After the flushing of the water purification chamber 21 is completed, the second scraper 262 is reset into the groove 221 under the drive of the elastic member.

[0068] It can be understood that the stiffness coefficient of the elastic member is moderate. When the water flow in the water purification chamber 21 impacts, the elastic member elongates. In the absence of water flow impact, under the contraction of the elastic member, the second scraper 262 can be reset into the groove 221.

[0069] Optionally, in an embodiment of the present invention, the elastic member can be one of an elastic band or a tension spring.

[0070] Preferably, in an embodiment of the present invention, in order to avoid the corrosion and failure of the tension spring, the elastic member is selected as an elastic band.

[0071] Although the settings of the first scraper 252 and the second scraper 262 can keep the top surface, side surface and bottom surface of the inner wall of the sewage chamber 22 clean, since the bottom surface of the first scraper 252 is soaked in sewage for a long time, scaling will occur on the lower surface of the first scraper 252, and it is difficult to remove the dirt at the bottom of the first scraper 252.

[0072] In order to scrape off the dirt on the bottom surface of the first scraper 252, the first scraper 252 is set as a "匚"-shaped plate with a lower opening, and the shape of the second scraper 262 is the same as the shape of the lower opening of the first scraper 252.

[0073] When the water in the sewage chamber 22 is discharged, the first scraper 252 descends under the action of gravity, scraping away the dirt on the inner wall side of the sewage chamber 22. When the first scraper 252 abuts against the bottom surface of the inner wall of the sewage chamber 22, the second scraper 262 is aligned with the lower opening of the first scraper 252. At the same time, the water flow in the clean water chamber 21 impacts the second scraper 262, causing the second scraper 262 to slide along the second guide rod 261.

[0074] Since the first scraper 252 and the second scraper 262 are in contact, the water in the water purification chamber 21 cannot flow to the left side of the second scraper 262. Therefore, a through hole 2621 is usually provided on the second scraper 262 so that the purified water can flow out smoothly.

[0075] The second scraper 262 slides along the second guide rod 261 under the impact of clean water, and the second scraper 262 simultaneously scrapes away dirt from the bottom surface of the first scraper 252 and the bottom surface of the sewage chamber 22, so that the first scraper 252 and the sewage chamber 22 can be kept clean.

[0076] It is understandable that the sum of the bottom surface area of ​​the first scraper 252 and the bottom surface area of ​​the inner cavity of the sewage chamber 22 is much larger than the surface area of ​​one side of the second scraper 262. The second scraper 262 is designed to minimize the area of ​​scale buildup in the sewage chamber 22 and the parts located in its inner cavity, so that the sewage chamber 22 is as clean as possible.

[0077] Understandably, in order to allow the second scraper 262 to slide smoothly, when the first scraper 252 moves to the bottom surface of the sewage chamber 22, the bottom surface of the first guide rod 251 is located between the upper surface 2521 and the lower surface 2522 of the first scraper (i.e., the bottom surface of the first guide rod 251 is located in the through hole cavity of the first scraper 252) or the bottom surface of the first guide rod 251 is flush with the lower surface 2522 of the first scraper. This guides the first scraper 252 without affecting the normal sliding of the second scraper 262.

[0078] Preferably, in one embodiment of the present invention, the bottom surface of the first guide rod 251 is flush with the lower surface 2522 of the first scraper, so that when the second scraper 262 scrapes off the dirt on the lower surface 2522 of the first scraper, it can also clean the bottom surface of the first guide rod 251.

[0079] Preferably, in one embodiment of the present invention, the lower part of the first scraper 252 is made of a plastic with a certain hardness, such as polyethylene or polypropylene, so as to ensure that the second scraper 262 does not damage the structure of the first scraper 252 when scraping off the dirt on the bottom surface of the first scraper 252.

[0080] Understandably, in order to clean the lower surface 2522 of the first scraper, when the second scraper 262 is located in the groove 221, the second scraper 262 is flush with the side wall of the sewage chamber 22, so that the second scraper 262 scrapes off the dirt starting from the rightmost side of the first scraper 252.

[0081] Preferably, in one embodiment of the present invention, in order to prevent sewage from flowing into the connecting pipe 241 from the through hole 2621, the outlets of the through hole 2621 and the connecting pipe 241 are misaligned, so that when the second scraper 262 is in the groove 221, the sewage is isolated from the connecting pipe 241, ensuring that the inside of the connecting pipe 241 is clean.

[0082] Preferably, in one embodiment of the present invention, in order to use the water flow flushed out of the through hole 2621 to rinse the inner wall of the sewage chamber 22, the through hole 2621 is arranged around the edge of the second scraper 262. When the water flow from the clean water chamber 21 flows out through the through hole 2621, it can rinse the dirt scraped off by the first scraper 252, resulting in a better scraping effect.

[0083] like Figures 7-11 As shown, preferably, in one embodiment of the present invention, in order to improve the rinsing effect, a nozzle 263 is provided in the through hole 2621. The left and right sides of the nozzle 263 are the inlet end 2631 and the outlet end 2632, respectively. The diameter of the inlet end 2631 is larger than the diameter of the outlet end 2632. According to Bernoulli's equation, the flow velocity of the clean water flowing out from the smaller outlet is greater than the flow velocity of the clean water at the inlet, which makes the water flow impact the dirt more forcefully, resulting in a better rinsing effect (cleaning effect).

[0084] Furthermore, such as Figure 8 As shown, the outlet end 2632 of each nozzle 263 faces the wall of the first scraper 252 on the same side as that nozzle 263. Specifically, the outlet end 2632 of the nozzle 263 located above the second scraper 262 faces the upper wall of the first scraper 252; the outlet end 2632 of the nozzle 263 located to the left of the second scraper 262 faces the left wall of the first scraper 252; the outlet end 2632 of the nozzle 263 located to the right of the second scraper 262 faces the right wall of the first scraper 252; and the outlet end 2632 of the nozzle 263 located below the second scraper 262 faces the bottom inner wall of the wastewater chamber 22. The orderly orientation of the outlet ends 2632 of the nozzles 263 towards different directions provides a higher impact pressure on the dirt adhering to the first scraper 252 and various locations within the wastewater chamber 22, further enhancing the cleaning effect.

[0085] The clean water chamber 21 only begins flushing when the first scraper 252 falls to the bottom of the wastewater chamber 22. This is usually achieved by installing a level sensor or a pressure sensor inside the wastewater chamber 22. This is a common technique in the field and will not be elaborated upon here.

[0086] like Figure 12 As shown, the wastewater recovery structure 40 is connected to the wastewater chamber 22 and is used to guide wastewater into the wastewater chamber 22. The wastewater recovery structure 40 includes a recovery pipe 41, a recovery tank 42, and a water delivery airbag 43. One end of the recovery pipe 41 is connected to the recovery tank 42, and the other end is connected to the sewer pipe. The recovery tank 42 is located below the wastewater chamber 22 and connected to the pipe of the wastewater chamber 22. The water delivery airbag 43 includes a first part 431 and a second part 432. The first part 431 and the second part 432 of the water delivery airbag 43 are connected and have the same volume. The first part 431 of the water delivery airbag 43 is located at the bottom of the recovery tank 42, and the second part 432 of the water delivery airbag 43 is located outside. The water delivery airbag 43 is filled with gas at half its volume (i.e., the first part or the second part is inflated).

[0087] When the recycling tank 42 contains wastewater, the wastewater compresses the first part 431 of the water delivery airbag, causing the gas to collect in the second part 432 of the water delivery airbag. The diameter of the pipe connecting the recycling tank 42 and the wastewater chamber 22 is larger than the diameter of the recycling pipe 41 and the recycling tank 42. When wastewater needs to be transported, the second part 432 of the water delivery airbag is compressed, causing the first part 431 of the water delivery airbag to expand within the recycling tank 42, thereby forcing the wastewater into the wastewater chamber 22.

[0088] It is understandable that, since the diameter of the pipe connecting the recycling box 42 and the sewage chamber 22 is larger than the diameter of the recycling pipe 41 and the recycling box 42, the sewage flows into the sewage chamber 22.

[0089] Understandably, in order to prevent sewage from flowing back from the sewage chamber 22, a one-way valve 242 is installed on the pipe connecting the sewage chamber 22 and the recovery tank 42.

[0090] Understandably, the second part 432 of the water-delivery airbag 43 is located on the side of the toilet body 10 to facilitate the user's squeezing of the second part 432 of the water-delivery airbag 43. When the user needs to use the toilet, the user steps on the second part 432 of the water-delivery airbag 43 while walking, causing sewage to be delivered into the sewage chamber 22.

[0091] When the user flushes the water tank, the sewage in the sewage chamber 22 is flushed out, and the sewage will not accumulate in the sewage chamber 22 for a long time, so that the water tank 20 can remain clean for a longer period of time.

[0092] The recycling pipe 41 is equipped with a valve near the drain pipe (sewage), and a filter screen 413 is installed on the inner wall of the recycling pipe 41. At least one first inlet pipe is installed on the recycling pipe 41 between the filter screen 413 and the valve. As mentioned above, the first inlet pipe is usually connected to the handwashing sink or vegetable washing sink, thereby guiding the wastewater into the recycling tank 42.

[0093] The filtration of filter screen 413 allows larger contaminants to be filtered out, ensuring that the wastewater is relatively clean.

[0094] A second water inlet pipe is provided between the filter screen 413 and the recycling bin 42. The second water inlet pipe is connected to the tap water pipe. When it is necessary to flush the recycling pipe 41 to prevent it from becoming clogged, the valve is usually opened to flush the dirt adhering to the filter screen 413 into the sewer pipe.

[0095] The recycling bin 42 is usually large enough to store a significant amount of wastewater. However, it should not be too large to prevent excessive wastewater storage, which could lead to fermentation and unpleasant odors.

[0096] A pressure sensor is usually installed at the valve. When the recovery tank 42 is full, the water in the first inlet pipe accumulates in the recovery pipe 41. The pressure sensor detects this signal and controls the valve to open, ensuring smooth drainage.

[0097] The recycling pipe 41 is usually connected to the upper part of the recycling bin 42 to prevent the sewage in the recycling bin 42 from being discharged along with the wastewater during drainage.

[0098] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
