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.

The bed pan having outer edge can be placed in a bidet and supported by the edge of the bidet; the front end of the bed pan is provided with a flushing nozzle so as to connect the soft pipe to the tap water; and the back end of the bed pan is provided with a small hole connected to the discharge soft pipe. The invention has the advantages of reducing the water usage for flushing the urine and obvious water-saving effect.

The invention discloses a separated-drainage type water-saving pedestal pan, which consists of a bed pan as well as a drain pipe and a washing pipeline with traps. The separated-defecation type water-saving pedestal pan is characterized in that the lowest point of the trap of the pedestal pan is provided with a small hole, and a urinate drainage thin tube connected in series with the trap and a pedal switch is arranged under the trap of the pedestal pan; a multi-hole sprayer for specially washing the urine by directly using the tap water is arranged on a pan edge; and a defecation drainage pipe outlet with the trap is provided with a water-sealing deodorizing valve. Therefore, the composition, the work condition and the flushing quantity of the pedestal pan are similar to that of a urinal. The separated-drainage type water-saving pedestal pan has the advantages of greatly reducing the urine flushing quantity of the pedestal pan with obvious water-saving effect.

The present invention relates to a kind of cistern device for flushing closet and the cistern is one closed container. The pressure of incoming water is utilized to produce compressed air in the cistern, so that water under the action of both its own gravity and compressed air inside the cistern can flush toilet with relatively high speed and thus less water consumption. Compared with available common cistern, the present invention can save water without additional power consumption.

The invention specially relates to an intelligent flushing method and system for a toilet bowl. The method comprises the following steps that a urinal image is collected at preset frequency; the urinal image is identified, and positioning information of a target cleaning object in the urinal image is obtained; a cleaning instruction is generated according to positioning information and sent to anautomatic toilet bowl cleaning device so as to drive the automatic toilet bowl cleaning device to clean the target cleaning object. Accordingly, by collecting the urinal image, the target cleaning object is positioned, then the automatic toilet bowl cleaning device is adopted, for example, a brush attached to the toilet bowl is used for brushing the position where the target cleaning object is located, that is to say, the target cleaning object can be cleaned away rapidly, the technical scheme is simple and high in feasibility, not only can hygiene and attractiveness of a toilet be kept, but also a user can use the toilet merrily, continuous flushing is not needed while the living quality of the user is improved, and the flushing amount is saved.

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.
