Description
A water-saving toilet Technical Field
[0001] This invention relates to the field of water-saving toilets. This new toilet structure can effectively use very little water to flush the toilet very cleanly, while saving bathroom space. It is especially suitable for use as a toilet in RVs and for the renovation of rural dry toilets. Background Technology
[0002] This invention is based on the technology disclosed in my application, CN110453762 B, which involves filling a sealed cavity with flowing water and using a scraper to move the water-filled cavity along the inner wall of the toilet to clean it. Apart from this, the applicant has not found any similar technology or solution. Technical issues
[0003] However, existing toilets using this technology have complex structures, and many areas of the toilet's inner wall, except for the latrine, cannot be cleaned. Existing technologies also lack devices for cleaning other parts of the toilet's inner wall besides the latrine and scraper. Furthermore, existing technologies do not consider the utilization of the RV's grey water tank when used as a RV toilet. Therefore, a novel mechanism suitable for the aforementioned invention has been designed, maximizing water conservation while having a simpler structure and smaller footprint. This not only facilitates the use of rural dry toilets but also benefits RV use. Additionally, the ventilation openings on the toilet allow for the extraction of odors generated during defecation, preventing them from escaping the toilet and making toilet use more comfortable. Technical solutions
[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows: a water-saving toilet, including a shell, a toilet seat base, a trough, a scraper, a scraper brush, a lid, a bottom cover, etc. All components corresponding to the above-described names are solids or shells with a certain shape, width, length, and thickness. It also includes a power supply, a control device, a drive motor, a threaded screw, a shaft, a water pump, etc.; a shell is provided, and after hollowing out the interior of the shell, a fecal outlet and an odor outlet are provided on the shell. The fecal outlet is located at the lower end of the shell, and the odor outlet is located at the rear end of the shell. An exhaust fan can be installed on the odor outlet, so that the odor is directly exhausted through the exhaust fan during toilet use; two... There are two holes, called toilet seat base hole I and scraper block connection hole I, both of which horizontally penetrate the shell. Toilet seat base hole I is positioned slightly below the front end of the shell, and scraper block connection hole I is located between the odor outlet and toilet seat base hole I. The toilet seat base and scraper block are rotatably mounted on their respective holes I. Based on this layout, one or two (at least one) plate-like structures protruding from the shell's interior are placed vertically behind scraper block connection hole I. These are called scraper block brush fixing plates. The scraper block brush fixing plate can be integral with the shell or connected to it via mechanical components. A hole, called the scraper brush fixing plate hole, is provided. There is at least one such hole. A threaded rod is provided, passing through the scraper brush fixing plate hole. One end of the threaded rod is connected to the drive motor, and the other end passes through the scraper brush and is rotatably connected to the coupling thread on the scraper brush. In this invention, the scraper brush is cuboid in shape, with through holes on its top and bottom surfaces in the vertical direction, called scraper brush holes. The inner wall of the hole is threaded and coupled to the aforementioned threaded rod. When the threaded rod rotates, the scraper brush can reciprocate. The scraper brush can move along the threaded rod to any of the following surfaces: left, back, or right. The scraper is positioned such that its three sides are in close contact with the corresponding parts of the inner wall of the shell through rubber rings protruding from the outer surface of the scraper. The rubber rings are installed on the front, back, left, and right sides of the scraper, and there are at least two rubber rings. A certain space is formed between the two rubber rings. When the scraper moves to be parallel and in contact with the front plane of the scraper, the space between the rubber rings on the front, back, left, and right planes of the scraper forms a sealed space with the shell and the scraper. A scraper water inlet hole and a scraper water outlet hole are provided on the scraper and communicate with this space. Water can flow through the scraper water inlet hole inside the rubber ring and then be discharged from the scraper water outlet hole.The scraper block is also rectangular. On the opposite side, perpendicular to the surface that contacts the scraper block brush (mentioned above), there is a scraper block connection hole II. A rotating shaft can pass through this hole and the scraper block connection hole I on the shell, allowing the scraper block and shell to be rotatably connected. Simultaneously, the scraper block has a clean water inlet and a circulating water inlet, as well as a clean water outlet and a circulating water outlet. The clean water inlet connects to the clean water tank, and the clean water outlet connects to the circulating water tank. Both the circulating water inlet and outlet connect to the circulating water tank. When used in the RV, the grey water tank can be used as a circulating water tank. During use, a circulating water tank is installed on the shell. The scraper block also has at least four protruding rubber rings, connected end-to-end and matching the shape of the scraper block, forming two independent sealed spaces with the toilet bowl. One sealed space is connected to clean water, and the other is connected to the circulating water tank. The circulating water sealed space is located in front of the clean water sealed space, meaning the toilet bowl is first cleaned by circulating water, and then thoroughly cleaned by clean water, achieving water-saving and cleanliness. The toilet bowl is semi-circular, with an interior semi-circular shell cut off by the corresponding scraper block's circumferential rotation. When the scraper block extends into the toilet bowl and rotates, there is no... In any position, the three sides of the toilet bowl are tightly fitted to the three sides inside the bowl via a protruding rubber ring on the scraper. This ensures that water in the sealed clean water space and circulating water space formed by the rubber ring, scraper, and bowl can only flow to the circulating water tank through the clean water outlet and circulating water outlet. Simultaneously, at one end of the bowl, a portion protrudes, called the bowl protrusion. This protrusion protrudes horizontally from the bowl's outer shell by at least 2-3 times its thickness. One side of the protrusion is on the same horizontal line as the bowl's opening, with a slight indentation from the center to both sides. The toilet seat base is equipped with features for easy rotation. The toilet seat base connection hole II through which the shaft passes can rotatably connect the toilet seat base and the shell through the rotating shaft and the toilet seat base connection hole I located on the shell. A semi-circular gear is provided on the toilet seat base connection hole II, which is integrated with the toilet seat base connection hole II. The drive motor can drive the toilet seat base to rotate through the gear. Similarly, a toilet bowl tray and a toilet seat connecting rod are provided on the toilet seat base, both on the toilet seat base connection hole II, which can be integrated with the toilet seat base connection hole II. The toilet bowl is fixed to the toilet bowl tray through the positioning rod located on the toilet bowl and the positioning hole located on the toilet bowl tray. There can be a padding layer between the toilet bowl and the toilet bowl tray.The toilet seat is U-shaped, or a square U-shape. At the midpoint of its bottom, a screw or other connecting component can be installed to permanently connect it to the toilet seat base via a connecting rod. At the upper ends of the U-shaped toilet seat, there are toilet seat connection holes I. The seat body consists of two plates of a specific shape, and on these two identical plates, there are also toilet seat connection holes II, the same size as toilet seat connection holes I on the toilet seat. A shaft allows for a rotatable connection between the seat body and the toilet seat. A lid is then installed. The toilet seat cover is a shell of a certain thickness, its shape corresponding to part of the shell's shape. Its interior is hollowed out to cover a portion of the shell. A cover hole (II) is provided on the cover cover, and a cover hole (I) is provided in the corresponding position on the shell. At the lower edge of the cover cover, corresponding to the position of cover hole II, two small balls are provided, integral with the cover cover, positioned where the opening of the toilet bowl meets the edge of the inner surface of the shell. Simultaneously, a bottom cover is provided, its shape matching the corresponding position on the shell, allowing it to be fixed to the toilet seat base for aesthetic purposes.
[0005] The shell is a hollowed-out shell of a certain thickness with a specific shape. It has an exhaust outlet for a fan to draw odors from the toilet bowl outside, and horizontally penetrating holes for the scraper and toilet seat base. Near its top, there is a cover hole for a rotatable cover plate. On the inner wall of the shell near the scraper connection hole, there is a protruding scraper brush fixing plate, which can be of any shape. This scraper brush fixing plate has a fixing hole, and there is at least one such plate. The scraper brush fixing plate can be integral with the shell, or... The toilet can be connected to the shell by certain components. A sealing water plate is provided at the attachment of the scraper block connection hole I on the shell. The shell can also be replaced. The replaced shell has a cover plate hole and a toilet seat base hole, and is also provided with a scraper block brush movable cavity. The scraper block brush is located in it. The feces outlet and the scraper block brush movable cavity form a 90-degree angle or greater than 90 degrees. The space enclosed by all the surfaces parallel to the movement direction of the scraper block brush movable cavity, except for the outer edge shape of the corresponding toilet bowl opening surface and the feces outlet part which are empty, is completely continuous and sealed.
[0006] The latrine has a standard semi-circular bottom surface inside, where two vertical horizontal planes intersect with the bottom surface. The junctions of the three surfaces are rounded. Along the horizontal direction of the latrine opening, there is a protruding latrine protrusion. The front end of the protruding latrine protrusion can extend 5-10cm beyond the nearest outer surface of the latrine. At the bottom of the latrine, there is a positioning rod integral with the latrine. The latrine can also have a corresponding alternative latrine, identical to the latrine described in CN110453762 B, which is equipped with a threaded screw and a motor as a drive device. The fecal collection space is considered "U"-shaped before being specified, and the feces excreted during defecation are located in the "U". The bottom of the U-shaped toilet bowl has one side open when viewed from the front. Directly below this open side, there is a protruding part that is integrated with the toilet bowl. Part of this part is on the same plane, and the feces flow out through this side to the feces outlet. The scraper is located in the U-shaped space. The difference is that, as in this solution, the toilet bowl can be divided and placed on the toilet seat base of this solution. The scraper corresponding to this slot is the one described in the announcement number CN110453762 B, which is existing technology and will not be described in detail here.
[0007] The toilet seat base has a toilet seat base connection hole II. The hole has a certain thickness and has a toilet seat connecting rod and an integral toilet bowl tray. The shape of one side of the toilet bowl tray is consistent with the shape of the bottom outer surface of the toilet bowl. The toilet seat connecting rod is located under the toilet bowl tray.
[0008] The toilet seat is a U-shaped entity on the same plane. At the bottom of the U-shape, there are screws or other connecting parts that are fixedly connected to the toilet seat connecting rod. The toilet seat can also be integrated with the toilet seat base. On both sides of the top of the U-shaped toilet seat, there are toilet seat connecting holes I. The ring body is rotatably connected to the toilet seat through the toilet seat connecting holes II provided on the ring body by a shaft. The U-shaped entity on the toilet seat and the ring body together form the toilet seat.
[0009] The scraper block described herein is based on the same principle as that described in announcement number CN110453762 B. However, in order to achieve greater water conservation and cleaner operation, and to make it more suitable for use in RVs, this solution increases the original "cavity" to two based on the original technology. On the basis of the original solution, an independent circulating water inlet and outlet are set and connected to another independent "cavity". A corresponding clean water inlet and outlet are set for this independent "cavity", and the circulating water inlet is directly connected to the RV's grey water tank through pipes and a water pump.
[0010] The aforementioned scraper has a specific shape. In this design, it has a four-sided cuboid structure. When the scraper moves to a position parallel to one face of the scraper brush, all surfaces parallel to the scraper brush's direction of movement are movably fitted by protruding rubber rings and all surfaces within the shell parallel to the scraper brush's direction of movement, as well as one surface of the scraper brush. The rubber rings are located on the scraper brush, surrounding all surfaces parallel to the scraper brush's direction of movement. The rubber rings surrounding the scraper brush parallel to the scraper brush's direction of movement can form a cavity consistent with the principle described in CN110453762 B. The key point is that there can be two cavities, which are connected to clean water and circulating water respectively, and are independent of each other. There are through scraper brush holes on the upper and lower surfaces of the scraper brush. Threads are engraved on the inner surface of the scraper brush holes and coupled with a threaded screw. When the threaded screw rotates, it moves in a certain direction. Beneficial effects
[0011] Through the above design scheme, the present invention can bring the following beneficial effects:
[0012] The technical solution of this invention can save more water and be cleaner and more hygienic by setting up a circulating water tank and increasing the number of "cavities" on the scraper block. Especially when used as a toilet in a motorhome, it can be directly connected to the grey water tank, making its structure more reasonable, simpler and more water-saving when used as a toilet in a motorhome.
[0013] The technical solution of this invention, by setting a protruding part in the toilet bowl, ensures that feces flow along a preset path within the recess, regardless of viscosity, without contaminating other parts of the shell that cannot be cleaned. This keeps more of the interior of the shell clean, making it easier for feces to flow into the latrine. At the same time, this structural layout is more conducive to different amounts of feces, especially excess feces generated during a single toilet visit, which can flow smoothly to the feces outlet without being blocked and contaminated by the scraper block. In the overall structure of this invention, not only can excess feces not contaminate the scraper block when poured out, but more importantly, less of the inner surface of the shell is contaminated during the process of feces entering the latrine, and most of the contaminated inner surface can be cleaned.
[0014] By setting a toilet seat base, the toilet seat structure is made simpler, the layout is more elegant, and the appearance is more beautiful. Most importantly, as a RV toilet, it is not only lightweight, but its trough can also be made of ceramic material so that it will not be damaged by bumps. When used as an RV toilet, combined with the trough protrusion, after cutting off the fecal outlet and the surrounding part, any part inside the toilet can be cleaned without dead angles.
[0015] The toilet seat opens and closes automatically via a slot, effectively concealing all internal mechanical components and providing a pleasing visual effect whether the toilet is being used, cleaned, or left to rest. Furthermore, the material and color of the seat can be customized to meet diverse aesthetic needs.
[0016] By installing a water-sealing plate on the casing, the number of water pumps or valves can be reduced. This prevents water flowing through the scraper block from overflowing and flowing towards the scraper brush, and then to the corresponding water tank. Attached Figure Description

The best embodiment of the present invention
[0040] The following description, based on all the accompanying drawings and the technology described in my application (CN110453762 B), describes the embodiments of the present invention. As shown in the figures, the toilet seat base 3 is rotatably connected to the shell 1 via a toilet seat base connection hole II 31 on the toilet seat base 3 and a toilet seat base connection hole I 13 on the shell 1. The toilet seat 6 is immovably mounted on the toilet seat connecting rod 33 on the toilet seat base 3. When the toilet is not in use, the toilet seat 6 is flat and T-shaped when viewed from the right. The toilet bowl 2 is immovably mounted on the toilet bowl tray 32 on the toilet seat base 3 inside the shell 1. The positioning rod 22 on the toilet bowl 2 extends into the positioning hole 34 on the toilet seat base 3. The scraper block 4 is rotatably mounted on the shell 1 via a scraper block connection hole I 11 on the shell 1 and a scraper block connection hole II 41 on the scraper block 4, as described in CN110453762. As described in technology B: (The scraper block has a similar end face that matches the shape of the toilet bowl surface. A scraper ring is provided on this end face through a groove. The scraper ring is a continuously closed rubber ring. The scraper ring, the end face on the scraper block, and the toilet bowl surface form a sealed cavity. A water injection hole is provided on the scraper block for injecting water into the cavity.) The key point is that, in this embodiment, the number of cavities is increased to two. Although they are both located on the scraper block 4, they are independent of each other. Each cavity is independently provided with a clean water inlet hole 42 and a clean water outlet hole 43, as well as a clean water connection and a circulating water inlet hole 44. The circulating water outlet 45 is connected, while the clean water cavity and the circulating water cavity are independent of each other. Water from the clean water outlet 43 flows into the circulating water tank. The circulating water inlet 44 and the circulating water outlet 45 are also connected to the circulating water tank via a water pump and water pipes. Alternatively, the clean water outlet 43 and the circulating water inlet 44 can be connected. Especially when this toilet is used as a motorhome toilet, the motorhome grey water tank can be used as a circulating water tank, saving not only toilet costs but, more importantly, water. Additionally, a scraper brush 5 (existing technology, except for the one with announcement number CN110453762) can be added. Besides B, the applicant has not found any toilet mechanism specifically for cleaning the scraper block (4). The key issue is that the existing toilet technology has a complex structure, and many places inside the shell that are contaminated by feces cannot be cleaned. Moreover, the existing technology is not conducive to the toilet structure layout and is costly. The scraper block connecting hole I11 and the odor outlet 15 are located inside the shell 1, and below the scraper block brush fixing plate 14. On the scraper block brush 5, there is a scraper block brush hole 51 that runs vertically through the scraper block brush, and the scraper block brush hole 51 is engraved with threads.A scraper brush fixing plate 14 extends from the inner wall of shell 1, integral with shell 1. The scraper brush fixing plate 14 has a through-hole 12, through which a threaded rod is provided, allowing it to pass through the through-hole and the scraper brush hole 51 on the scraper brush 5, movably connecting the scraper brush 5 and the scraper brush fixing plate 14. The cover plate 7 is rotatably mounted on shell 1 via cover plate hole I 17 and cover plate hole II 71. All the moving parts described above are driven by motors controlled by CPU, MCU, etc., which is mature technology and will not be elaborated further. Embodiments of the present invention
[0041] The embodiments of the present invention will now be described with reference to all the accompanying drawings. As shown in the drawings, the toilet seat base 3 is rotatably connected to the shell 1 via a toilet seat base connection hole II 31 on the toilet seat base 3 and a toilet seat base connection hole I 13 on the shell 1. The toilet seat 6 is immovably mounted on the toilet seat connecting rod 33 on the toilet seat base 3. The toilet seat 6 is flat and T-shaped when viewed from the right. The toilet bowl 2 is immovably mounted on the toilet bowl tray 32 on the toilet seat base 3 inside the shell 1. The positioning rod 22 on the toilet bowl 2 extends into the positioning hole 34 on the toilet seat base 3. The scraper block 4 is rotatably mounted on the shell 1 via a scraper block connection hole I 11 on the shell 1 and a scraper block connection hole II 41 on the scraper block 4. The scraper block brush 5 is located inside the shell 1 and scrapes the toilet bowl. Between the block connecting hole I11 and the odor outlet 15, and below the scraper brush fixing plate 14, the scraper brush 5 has a vertically penetrating scraper brush hole 51, and the scraper brush hole 51 is engraved with threads; the scraper brush fixing plate 14 extends out of the inner wall of the shell 1 and is integral with the shell 1. The scraper brush fixing plate 14 has a vertically penetrating scraper brush fixing plate hole 12, and a threaded screw is provided so that it can pass through the hole and the scraper brush hole 51 on the scraper brush 5 to movably connect the scraper brush 5 and the scraper brush fixing plate 14; the cover plate 7 is rotatably mounted on the shell 1 through the cover plate hole I17 on the shell 1 and the cover plate hole II71 on the cover plate 7; all the moving parts mentioned above are driven by a CPU-controlled motor, which is a mature technology and will not be described in detail. When using the toilet: (For ease of explanation, the toilet bowl opening is specified as clockwise) Press the defecation button located near the toilet. The toilet seat base 3 rotates clockwise. As it rotates, the toilet bowl 2 and toilet seat 6 installed on it also rotate synchronously. The lid 7 is lifted from the inside of the lid 7 by the edge of the toilet bowl 2 closest to the lid 7, so that the movement of the lid 7 is driven by the toilet bowl 2. When the opening of the toilet bowl 2 is horizontal, the toilet seat 6 is vertical and in contact with the ground. The person using the toilet can manually rotate the ring 61 on the toilet seat 6 to the horizontal position and then start defecating. At this time, the exhaust fan starts to work. Since the lid 7 and the end part of the toilet bowl 2 covered by the lid 7 and part of the cavity inside the shell 1 form a "pipe"-like environment, the odor generated when using the toilet is drawn out of the toilet by the exhaust fan through the odor outlet 15.When the opening of the toilet bowl 2 is parallel to the ground and the exhaust fan is running, the scraper 4 begins to rotate counterclockwise to the cleaning start position, that is, the surface of the scraper 4 facing the bottom of the toilet bowl 2 is parallel to the ground, and the side is perpendicular to the ground. After using the toilet, press the feces cleaning button located near the toilet. The scraper brush 5 is driven by the threaded screw, and its position moves vertically upward from near the feces outlet 16 to near the scraper brush fixing plate 14, and is located above the scraper connecting hole I11. At the same time, the toilet seat base 3 rotates counterclockwise. The drive ball 72 on the cover plate 7, because it is on the horizontal plane of the two vertical surfaces of the toilet bowl 2, will lift the cover plate 7 due to the combined force, so that the movement of the cover plate 7 is driven by the toilet bowl 2 and follows it. At the same time, the ring 61 on the toilet seat 6 is driven by the ring on the shell 1. The sloping edge rises, its surface gradually changing from horizontal to vertical; as the latrine 2 continues to tilt, the feces in the latrine 2 will flow along the latrine protrusion 21 located on the latrine 2 towards the bottom of the toilet. When the opening surface of the latrine 2 is perpendicular to the ground, the latrine 2 stops moving. At this time, the scraper block 4 passively moves and extends into the latrine 2. The toilet seat 6 is parallel to the ground, and the ring body 61 located on the toilet 6 is perpendicular to the ground. When the opening surface of the latrine 2 is perpendicular to the ground and stops moving, the scraper block 4 extended into it begins to rotate clockwise to begin cleaning. As the scraper block 4 begins to rotate... The circulating water pump starts working, and the clean water switch is also turned on. Water from the circulating water tank flows back to the circulating water tank through the circulating water inlet 44, circulating water channel 47, circulating water outlet 45, and water pipe on the scraper block 4, continuously circulating and cleaning. Clean water also enters the circulating water tank through the clean water inlet 42, clean water channel 46, and clean water outlet 43 on the scraper block 4, flowing continuously. When one side of the scraper block 4 is flush with the opening of the toilet bowl 2, the inside of the toilet bowl 2 is cleaned, and the scraper block 4 and the water pump stop working, meaning the clean water and circulating water stop flowing. The flow is stopped. Then, the scraper brush 5 moves to the fecal outlet 16 through the three surfaces of the shell 1, the edge of the opening surface of the toilet bowl 2, and one of the scraper blocks 4 that are flush with the opening surface of the toilet bowl 2. At the same time, the driving device drives the water in the circulating water tank to circulate continuously through the scraper brush water inlet 52, the scraper brush water channel 54, and the scraper brush water outlet 53. When the scraper brush 5 moves to the lowest end of the toilet bowl protrusion 21, the space below the scraper brush 5, including the fecal outlet 16, is sealed, odor is isolated, and cleaning is completed.When using the replaceable shell 10 and the replaceable toilet bowl 9, the replaceable toilet bowl 9 is located on the toilet seat base 3, and the toilet scraper brush 5 is located in the toilet scraper brush cavity 107 on the replaceable shell 10. The replaceable toilet scraper brush 5 is movably connected to the replaceable toilet scraper brush fixing plate hole 105 on the replaceable shell 10. During toilet use, the replaceable toilet bowl 9 moves through the toilet seat base 3 to a position where its protruding part 91 is perpendicular to the ground, and part of it is located within the toilet scraper brush cavity 107 on the replaceable shell 10. At this time, the toilet scraper brush 5 moves to the replaceable toilet bowl 10. The scraper brush fixing plate I104 on the substitute shell 10 is attached so that after using the toilet, the replaceable toilet bowl 9 moves until the toilet bowl protrusion 91 is parallel to the ground and its outer edge coincides with one surface inside the scraper brush cavity 107. Feces flow into the scraper brush cavity 107, and the scraper brush 5, driven by the driving device, moves along the scraper brush cavity 107 towards the feces outlet I106 located on the replaceable shell 10. Feces flow into the toilet bowl through the feces outlet I106, and the replaceable shell 10 and the scraper brush are cleaned, completing the toileting process. Industrial applicability
[0042] The toilet is constructed entirely of ceramic and plastic, utilizing mature manufacturing technologies and processes. For example, the sealing and lubrication of the cavity formed by the rubber body and ceramic or plastic surfaces are well-established; water is sufficient for lubrication. The drive components, such as the MCU, motor, and lead screw, are also mature technologies. This toilet is not only easy to maintain but also highly adaptable to different countries and regions. For instance, adding a temperature sensor and heating device allows for use in extremely cold regions. Since these are mature technologies, further details are omitted. However, as it has not yet been commercialized, the application of these technologies requires further verification. Sequence List Free Content
