Description

Technical Field

[0001] This invention belongs to the field of toilet and bathroom equipment. Background Technology

[0002] Existing rotary piston toilets use a lifting cylinder to control the rise and fall of a piston (sealing disc) to seal and open the toilet's drain outlet. The cylinder is often fixed using a support structure, which is cumbersome to install, costly, prone to shifting, and difficult to clean. The sealing disc and cylinder enter the toilet pipe through a mounting hole at the rear of the toilet, sealed with a sealing plate. Toilet maintenance requires moving the toilet and opening the sealing plate, which is inconvenient. International patent applications PCT / CN2023 / 123649 and PCT / CN2023 / 091939 exhibit these characteristics. Summary of the Invention

[0003] This invention relates to a toilet with a circular groove in its pipe. The toilet pipe includes a circular groove located below the toilet bowl's drain outlet. The bottom of the groove connects to the surrounding toilet bowl pipe, forming a ring-shaped sewage channel. The circular groove, toilet pipe, and ring-shaped sewage channel are an integral structure, with the toilet bowl cylinder fixedly installed within the groove. A water inlet or air inlet pipe for the toilet bowl cylinder is located within the groove, extending from the bottom of the groove and the bottom of the toilet body to connect with the main pipe. This design improves the stability of the connection between the bottom of the ring-shaped sewage pipe and the toilet body. The toilet bowl cylinder's location below the toilet bowl's drain outlet facilitates installation and maintenance.

[0004] After the waste from the toilet bowl falls from the drain outlet and sealing plate, it reaches the circular sewage pipe and then enters the toilet drain. The tub is located inside the circular groove, making it difficult for waste to contaminate it, which helps keep the tub clean and achieves a cleaner overall toilet.

[0005] The toilet includes a sealing flange, the inner side or bottom of which is sealed and fixedly connected to the cylinder, the flange is sealed and fixedly connected to the upper port of the circular groove, or the flange and the upper bottom of the cylinder are an integral structure.

[0006] The sealing flange is fixed to the circular groove with screws. A seal is installed between the flange and the circular groove, and a seal is also installed between the screws and the through hole of the flange to achieve a seal. The inside of the circular groove under the flange and the toilet pipe are mutually isolated from air circulation.

[0007] The through-hole and fixing screws of the sealing flange are located outside the vertical projection of the sealing disc onto the flange surface.

[0008] If the toilet bowl, water inlet pipe, or rotating sealing disc bearing malfunctions, the control sealing disc and pull rod retract. By using an extended sleeve tool set to loosen or tighten the flange screws through the toilet drain outlet, repairs can be performed without moving the toilet or opening the mounting holes at the back of the toilet, making repairs convenient.

[0009] A bearing is installed between the pull rod and the sealing plate, or the pull rod and the bottom of the sealing plate are a bushing structure. The sealing plate can rotate. The toilet includes a water spray pipe with the water spray nozzle facing the toilet sealing plate. The water spray pipe is connected to the main pipe and enters the interior of the round groove from the bottom of the toilet body and the bottom of the round groove, and then exits from the sealing plate.

[0010] Preferably, the water spray pipe and the cylinder inlet pipe (or inlet pipe) are the same pipe within the circular groove, but are different branches of the main pipe. The water spray nozzle of the water spray pipe faces the bottom of the toilet's sealing disc, and the water jet impacts the sealing disc, causing it to rotate. The falling tailwater lands on the outer wall of the circular groove, which can flush the outer wall and the toilet's annular sewage channel.

[0011] The toilet also includes a second water spray pipe that passes through the cylinder sealing flange or the inner wall of the circular groove, with the spray nozzle facing the annular sewage channel.

[0012] A third spray pipe is installed in the ring pipe of the toilet to specifically flush the toilet's sewage pipe, which helps to keep the toilet's sewage pipe and drain pipe cleaner.

[0013] The toilet bowl cylinder is installed in the circular groove directly below the drain outlet. This is more convenient than a structure using a support component. In this invention, the cylinder is located directly below the drain outlet. During use, there may be situations where the drain outlet is opened by forcefully pressing the sealing plate. The cylinder sealing plate and the circular groove base are reliably stable. In contrast, the support component structure, due to its length and suspended nature, is prone to structural displacement, affecting usability. This invention is also more cost-effective than using a support component structure.

[0014] In this invention, the outer diameter of the upper part of the circular groove is more than 80 mm and the bottom is larger. After the toilet paper and other waste fall into the drain outlet, they are not easily caught. In the prior art, the diameter of the toilet bowl at the bottom of the toilet is small. After the toilet paper and other waste fall into the drain outlet, they are not easily detached from the bowl and are not conducive to cleaning.

[0015] In traditional toilets with a supporting structure, the spring in the cylinder has an exhaust vent at the bottom or side. This cavity is often very damp and may retain dirt, making it unsuitable for spring steel springs. Spring steel springs have better fatigue strength and are cheaper than stainless steel springs, which are expensive and prone to fatigue. The toilet structure of this invention avoids these drawbacks and offers significant advantages.

[0016] In a toilet with a supporting structure, when there is backflow, the supporting components, the entire cylinder, including the cavity containing the spring, will be soaked. It is difficult to clean them by flushing the toilet itself, especially since the toilet pipes are even worse after backflow in toilets with the prior art. In the case of backflow, the cylinder flange and cylinder rod, the bottom surface of the sealing plate, and the toilet pipes of the present invention will be soaked. When the toilet is flushed by itself, all of the above parts are easily cleaned, which is a significant advantage. Attached Figure Description

First included angle (X). This invention relates to a toilet with a circular groove in its pipe. The circular groove is located below the toilet bowl's drain outlet within the toilet pipe. The bottom of the circular groove wall connects to the surrounding toilet bowl pipe, forming a ring-shaped sewage channel. The circular groove, toilet pipe, and ring-shaped sewage channel are an integral structure, with the toilet bowl cylinder fixedly installed within the circular groove. A water inlet pipe or air inlet pipe for the toilet bowl cylinder is located within the circular groove, extending from the bottom of the circular groove and the bottom of the toilet body to connect with the main pipe. The bottom of the ring-shaped sewage pipe is connected to the toilet body.

[0019] The method of fixing the cylinder to the circular groove is a mature component fastening technology. Commonly used screw fixing methods include: the circular groove includes a first through hole, and a nut is installed in the first through hole. The nut is fixed and cannot rotate, and the nut cannot move upward or has an upward movement limit. The cylinder has a through hole corresponding to the first through hole. The cylinder is fixed in the circular groove by screws. The first through hole and the through hole can be set at the bottom, middle or top of the circular groove and the cylinder.

[0020] Ring-shaped sewage pipes include both flat and inclined types.

[0021] The toilet bowl includes a bowl cavity, upper base, lower base, spring, piston, pull rod, and water or air inlet pipe. In the static state, the spring pushes the piston upward, the piston and pull rod are in the highest position, the toilet is sealed, pressurized water or gas enters through the water or air inlet pipe, the piston is compressed downward, the pull rod and sealing plate descend, and the toilet drain port opens.

[0022] Preferably, the toilet includes a sealing flange, the inner side or bottom of which is sealed and fixedly connected to the cylinder, or the flange and the upper bottom of the cylinder are an integral structure.

[0023] Preferably, the flange is sealed and fixedly connected to the upper port of the circular groove. The sealing flange is fixed to the circular groove by screws. A sealing element is installed between the flange and the circular groove. A sealing element is also installed between the screw and the through hole of the flange to achieve a seal, so that the air inside the circular groove below the flange and the toilet pipe is not circulated.

[0024] The through-hole and fixing screws of the sealing flange are located outside the vertical projection of the sealing disc onto the flange surface.

[0025] If the toilet bowl, water inlet pipe, or rotating sealing disc bearing malfunctions, the control sealing disc and pull rod can be retracted. By using an extended sleeve tool set to loosen the flange screws through the toilet's drain outlet, repairs can be performed without moving the toilet or opening the mounting holes at the back of the toilet, making maintenance convenient.

[0026] A bearing is installed between the tie rod and the sealing plate, or the tie rod and the bottom of the sealing plate are a bushing structure. The sealing plate can rotate. The cylinder sealing flange has a water spray pipe with the spray nozzle facing the toilet sealing plate. The water spray pipe is connected to the main pipe and enters the interior of the round groove from the bottom of the toilet body and the bottom of the round groove, and then exits from the flange.

[0027] When the toilet sealing disc is equipped with a sealing ring and is in its highest position, the sealing lip of the sealing ring seals against the upper edge of the toilet bowl pipe, the lower end surface of the drain outlet, the lower end face of the drain outlet flange, or the inner wall of the toilet bowl drain pipe.

[0028] Preferably, the water spray pipe and the cylinder inlet pipe (or inlet pipe) are the same pipe within the circular groove, and are branch pipes with the same end but different branches. The water spray nozzle of the water spray pipe faces the bottom of the toilet's sealing plate, and the water jet impacts the sealing plate, causing it to rotate. The tailwater falls onto the outer wall of the circular groove, which can flush the outer wall and the toilet's annular sewage channel.

[0029] Preferably, the toilet also includes a second spray pipe, which passes through the spray nozzle of the cylinder sealing flange and faces the annular sewage channel.

[0030] Preferably, the toilet also includes a third water spray pipe, which, when the sealing disc descends to the bottom or near the bottom, washes away dirt from the sealing disc with water flow, and the water flow does not pass through the center of the sealing disc, so that the water flow can drive the sealing disc to rotate.

[0031] The toilet sealing ring includes an annular mounting groove on the inner side, and a sealing lip around the mounting groove. When the sealing disc is in the highest position, the sealing lip of the sealing ring seals against the upper edge of the toilet bowl pipe, the lower port surface of the drain outlet, the lower end face of the drain outlet flange, or the inner wall of the toilet bowl drain pipe.

[0032] This invention relates to a toilet with a circular grooved pipe, comprising a toilet bowl, a sealing disc, and a sealing ring. The sealing disc seals the toilet bowl's drain outlet, while the sealing disc opens the drain outlet when it is away from the drain outlet. The sealing ring features an annular mounting groove on its inner side, with the sealing disc installed in this groove. The sealing disc and sealing ring seal against each other. A sealing lip surrounds the sealing ring, and this lip seals against the upper edge of the toilet bowl pipe, the upper surface of the lower drain outlet, the lower end face of the drain outlet flange, or the inner wall of the toilet bowl's drain pipe. The sealing disc can have various structures, such as a flat plate or a curved surface.

[0033] Preferably, the height of the sealing ring mounting groove is less than or equal to the thickness of the toilet sealing disc at the location where it is fitted, or the outer diameter of the mounting groove is less than or equal to the outer diameter of the sealing disc.

[0034] Preferably, the upper surface of the sealing ring includes an upward-facing sealing lip.

[0035] Preferably, the bottom of the sealing ring includes a bulge or a groove, wherein the bulge coincides with the diameter passing through the center of the sealing ring or forms a first angle of less than 45 degrees with the diameter.

[0036] Preferably, the upper part of the sealing ring includes a second sealing lip.

[0037] Preferably, the thickness between the upper and lower parts of the sealing ring is within 3 mm plus the thickness of the clamped rear sealing disc.

[0038] Preferably, the toilet bowl drain outlet is provided with a drain outlet flange, and the lower end face of the drain outlet flange is sealed to the sealing lip of the sealing ring.

[0039] Preferably, the sealing ring is elastic, and after the inner edge is pulled open, the mounting groove covers the sealing disc, and the inner edge of the upper surface of the sealing ring presses against the surface of the sealing disc, so that the sealing ring and the sealing disc form an integral sealing disc.

[0040] Preferably, the outer diameter of the independent sealing disc is smaller than the inner diameter of the toilet bowl's drain outlet. The independent sealing disc can be easily maintained through the drain outlet. After the sealing ring is installed on the sealing disc, the overall sealing disc can achieve a seal on the toilet bowl's drain outlet.

[0041] Using the sealing disc and sealing ring of this invention, the toilet does not need to have an installation hole at the rear. When the sealing disc, sealing ring, or cylinder needs maintenance, the sealing disc and sealing ring can be removed for maintenance without moving the toilet body.

[0042] Preferably, a portion of the annular area around the upper surface of the sealing ring has an upward-facing sealing lip, and the sealing surface has a conical structure. The conical structure provides greater support and sealing force, resulting in a better sealing effect. During toilet flushing, some of the water that falls onto the rotating sealing disc is rotated away from the sealing disc and falls into the toilet pipe. The tail water that leaves the upward-facing sealing lip falls into the toilet pipe at a higher position, which helps to clean the toilet pipe more thoroughly.

[0043] Preferably, the upper part of the sealing ring includes a second sealing lip, which improves the sealing effect.

[0044] Preferably, the bottom of the sealing ring includes a ridge or a groove, the ridge and the diameter passing through the center of the sealing ring coincide, the water flow from the water spray pipe below the sealing disc impacts the ridge or groove with greater friction than impacting the flat surface, and the sealing disc has greater rotational power.

[0045] Creating raised or recessed areas on the surface of a rubber seal is simpler, easier, and less costly than creating them on a metal or ceramic surface.

[0046] The sealing disc is fitted with the sealing ring. The toilet sealing disc is made of metal to prevent it from falling and damaging the ceramic surface. The sealing disc is made of ceramic or enamel to prevent itself and the ceramic surface from being damaged if it falls.

[0047] The sealing ring of this invention eliminates the need for a dedicated groove or hole in the sealing disc, and also eliminates the need for other corresponding sealing components in the toilet bowl, making the sealing structure of the toilet drain outlet simple and easy to keep clean.
