[detailed description of the invention]
Now be further elaborated a whole set of technical scheme of the present invention in conjunction with the drawings and the specific embodiments, this manufacturing technology is very clearly for a person skilled in the art.
The present invention adopts load-bearing pillar volume array or load-bearing screen, can the liquid and solid contaminant such as load-bearing, without hindrance collection urine, hair, fiber, silt and coordinate current to rinse the Method and Technology of pollutant; Adopt human bady gravitational or human body infrared induction to control current to open and close; Adopting inlet valve to control water inlet size, height of liquid level and current rinses strong and weak.
Load-bearing pillar volume array is by hard corrosion-resistant, the cylinder that length is identical or close of some smooth surfaces, material, the array of vertical-shaped arrangement composition at regular intervals.Cylinder can be, but not limited to the forms such as cylinder, cuboid, cone, spindle, square, spheroid, ellipsoid, tree-shaped body or fimbriatum, each cylinder top composition dot matrix, form class plane, can place and carry human body and weight, human body and below current are allowed to keep at a distance, interval is had between cylinder, can the liquid and solid contaminant of without hindrance the collection urine, hair, fiber, silt etc. that drop, when current flow through cylinder interval, can wash away smoothly via interval is without hindrance depending on each pollutant between damaged surface and cylinder.
Load-bearing screen is the plane body that there is space centre, can place and carry human body and weight, allow human body and below current keep at a distance, the liquid state such as the urine dropped, hair, fiber, silt and solid contaminant can fall into the guiding gutter of below by space, and are washed away by current.
Adopt pressure flow switch, utilize human bady gravitational to open to control current and close.When people stands on device, pressure flow switch opens, starts to rinse, and when people's separating device, pressure flow switch cuts out, and rinses and terminates.
Adopt inlet valve to control water inlet size, thus control flow check height of liquid level and current in pillar array rinse strong and weak, inlet valve is opened larger, more with water, and current liquid level is higher, and impulse force is stronger, and developing result is better.Otherwise inlet valve is opened less, less with water, current liquid level is lower, and impulse force is slightly poor, and developing result weakens, but can using water wisely.
