A siphonic, gravity-powered toilet is provided that includes a toilet bowl assembly having a toilet bowl. The toilet bowl has a rim channel provided along an upper periphery thereof and a direct-fed jet channel that allows fluid, such as water, to flow from the inlet of the toilet bowl assembly to the direct-fed jet outlet port into the interior of the toilet bowl, in the sump of the bowl. The rim channel includes at least one rim channel outlet port. In this toilet, the cross-sectional areas of the toilet bowl assembly inlet, the inlet port to the rim channel, and the outlet port to the direct-fed jet channel are configured so as to be optimized to provide greatly improved hydraulic function at low flush volumes (no greater than about 6.0 liters per flush). The hydraulic function is improved in terms of bulk removal of waste and cleansing of the bowl.

A flushometer for use with urinals or water closets includes a hollow valve body having an inlet, an outlet, and a valve seat therebetween. There is a piston or diaphragm movable in the hollow valve body to a closing position on the valve seat to control flow through the valve. A pressure chamber is above the piston or diaphragm for holding it on the valve seat. The piston or diaphragm includes a plurality of bypass orifices to connect the inlet with the pressure chamber to provide fluid to move the piston or diaphragm to the closing position.

The invention discloses a water-saving toilet. The water-saving toilet comprises a water tank, a squatting pan, a trap and a blow-down pipeline, wherein the water tank is made of ceramic and is provided with four side walls and a bottom wall; a round drain outlet which can be equipped with a single-press drain valve is formed in the bottom wall of the water tank; a drain transfer cavity is formed below the bottom wall of the water tank; a water diversion channel is formed in the top edge of the squatting pan; the round drain outlet is located above the drain transfer cavity which is connected with the water diversion channel in the top edge of the squatting pan; gas-guide pipes are arranged at the rear side of the trap and the blow-down pipeline; lower pipe orifices of the gas-guide pipes are directly connected with the blow-down pipeline and upper pipe orifices of the gas-guide pipes are located at the uppermost end of the drain transfer cavity; the horizontal projection positions of the upper pipe orifices of the gas-guide pipes are located at the periphery of a horizontal projection position of the round drain outlet, and deflects to one corner of a peripheral area of the round drain outlet. The water-saving toilet can be used together with the single-press drain valve, and can be used for realizing the condition that the flush water after urination is less than the flush water after defecation.

The invention discloses a scanning-type water flushing pedestal pan. A semicircular tubular hydraulic water tank type structure serves as a water flushing main body. The scanning-type water flushing pedestal pan is such represented that a spraying nozzle walking groove, which is as long as a half of inner ring, is arranged, and the section of half ring also functions as a half-arc shaped hollow piston running guide pipe of the semicircular tubular hydraulic water tank. As the semicircular tubular hydraulic water tank is filled with water, a semicircular tubular piston, pushed by pressure waterwhich overcomes elasticity of a tension spring, moves along the guide half-ring, and meanwhile, a spraying nozzle at the foremost end of the semicircular tubular piston flushes water towards the wallof a bedpan, so that scanning-type half-arc water flushing is formed. The semicircular tubular piston, pulled by an internal tension spring, gets contracted, and meanwhile, the spraying nozzle at theforemost end of the semicircular tubular piston squeezes remaining water in the hollow piston after stopping water supply. A pair of mechanisms are arranged in a mode of being symmetrically superposed about the walking groove, so that the scanning-type water flushing mechanism represented as a whole circle is formed. The pedestal pan conducts actions as locking a bicycle by a bicycle lock. The pedestal pan can reduce a water flushing amount to reach a flushing cleanness requirement.

The invention relates to a splash-proof micro-nano bubble toilet accessory device. The water inlet pipeline is connected to the flush valve through the micro-nano bubble generator, and the flush valve is connected to the toilet bowl through the flush pipeline; a water inlet electromagnetic valve is arranged on the water inlet pipeline , the control part is respectively connected with the solenoid valve and the sensor signal; the sensor receives the signal generated when the user approaches, and feeds back to the control part, and the control part controls the opening and closing of the water inlet solenoid valve. The micro-nano bubble water produced by the present invention directly enters the toilet bowl without passing through the water tank, thereby ensuring the maximum bubble concentration of the micro-nano bubble water entering the bowl; the micro-nano bubble water is prepared immediately for immediate use, preventing it from being used before the next use It disappears completely; a layer of ultra-dense foam layer floating above the water surface is formed in the toilet, which plays the role of anti-splash and odor isolation, and at the same time, it can form a layer of dense nano-bubble interface water on the inner wall of the bowl before and after each use film, thereby improving the anti-fouling ability of the inner wall.

The invention discloses an automatic drainage control device of a toilet bowl, wherein a first hydraulic cylinder, a second hydraulic cylinder, a first piston rod and a second piston rod are arranged in a water tank thereof; a transmission mechanism being capable of driving a valve cover plate to move up and down is arranged between the two piston rods and the valve cover plate; a first running water pipe, a first water exit, a second running water pipe and a second water exit are also arranged; the back end of the first water exit is communicated with the cavity of the first hydraulic cylinder; the back end of the second water exit is communicated with the cavity of the second hydraulic cylinder; the water outlet of the first running water pipe is also covered by a first rubber cushion; the water outlet of the second running water pipe is also covered by a second rubber cushion; a first pressure chamber is formed above the first rubber cushion; a second pressure chamber is formed above the second rubber cushion; the cover board is also coaxially and fixedly connected with a shifting block; a three-pronged transmission block is rotatablely arranged beside the shifting block; and afirst pressure relief valve and a second pressure relief valve are arranged beside the three-pronged transmission block. The automatic drainage control device can realize automatic flush without pressing a push button.
