The invention provides a sanitary washing apparatus, capable of increasing the water-saving efficiency and reducing the standby power. The local washing nozzle comprises: a water supply path configured to pass the wash water; an orifice configured to direct the wash water passed through the water supply path toward the human body part; a throat; a mixing chamber provided on a downstream side of the orifice and on an upstream side of the throat, an area of a cross section of the mixing chamber perpendicular to a discharge direction of the wash water being larger than an area of a cross sectionof the orifice perpendicular to the discharge direction; and an air intake portion configured to take air into the mixing chamber by a negative pressure generated by wash water flowing from the orifice toward the throat, a return flow is generated in the mixing chamber by wash water flowing out from the orifice and having a flow direction changed by a wall face of the mixing chamber, the air is sucked into the mixing chamber via the air intake portion being mixed into the return flow as an air bubble, and the return flow is mixed with the air joining wash water flowing from the orifice towardthe throat and is discharged from the throat.

The invention discloses a hydraulic high-efficiency water-saving toilet stool and relates to a water-saving toilet stool. The water-saving toilet stool comprises three systems, namely a main body system, a water tank system and a spray washing system. The main body system comprises a base, a tank body and a urinal; the water tank system comprises a wash-basin, a water accumulating tank and a water quality treatment tank; and the spray washing system comprises a water-saving spray washing device, a sewage intercepting and discharging device and a pedal hydraulic device. The wash-basin is positioned on the upper part of the water tank system and the bottom of the wash-basin is connected with the water accumulating tank; the bottom of the water accumulating tank is connected with the upper part of the water quality treatment tank and is communicated with the water quality treatment tank through a water feeding port; an automatic water-saving interchange valve is arranged inside the wateraccumulating tank; a plurality of layers of nano reverse osmosis filter screens and biological purification chambers are arranged at intervals inside the water quality treatment tank so as to recyclethe reclaimed water or waste water into pure water; the water-saving spray washing device is arranged on one side of the water accumulating tank and a water outlet stop valve which leads the accumulated water into the water-saving spray washing device is arranged inside the water accumulating tank; and the sewage intercepting and discharging device has the functions of directly discharging and stopping backward flowing and realizes spray washing and sewage drain through the pedal hydraulic device. The hydraulic high-efficiency water-saving toilet stool has the advantages of advanced technicalperformance, comprehensive and high-efficiency water conservation, extremely low installation and use cost, wide application and durability.

The invention relates to an automatic efficient water-waving flush valve comprising a valve body, a valve core and fittings, wherein the valve body comprises a sleeve, a drain hole, a discharge hole, a top cover and a bottom cover; the valve body is arranged at the outer side of the valve core and functions in fixing the valve core and forming a water absorption space; the valve core comprises a suction-discharge pipe, a valve plug, a floating body, a sliding bolt, a positioning bolt and a drain pipe; the suction-discharge pipe is arranged in the middle of the sleeve and penetrates through the bottom cover to be connected with the upper end of the drain pipe; the valve plug is arranged at an upper port of the suction-discharge pipe; the floating body is arranged in the middle of the valve plug; the floating body is provided with a through hole so that the upper end of the valve plug penetrates through the through hole to be in slide fit with the outer side of the valve plug; and the fittings includes a fixing nut, a lower gasket and an upper gasket. The automatic efficient water-waving flush valve is ingenious in design, excellent in performance, wide in application range, automatic in flushing, capable of adjusting the water amount, and preventing stoppage and filtering dirt, and eliminating leakage, convenient and fast to use, water-saving and efficient, firm and durable, easy to repair and replace, compatible with various water qualities, low in manufacturing cost and obvious in comprehensive benefits.

The invention provides a method for cultivating sugar-purpose sweet sorghum in sand wasteland. The method comprises the steps that when a tillage mode of convention planting film mulching or furrow cropping is adopted, wherein a mode of planting two plants in each hole is adopted in order to achieve the purpose of harvesting stalks, a mode of planting one plant in each hole is adopted in order toachieve the purpose of harvesting seeds, and a mode of planting one plant in each hole is adopted in order to achieve the purposes of harvesting both the stalks and the seeds; before planting after the soil is ploughed, 30t / ha farmyard fertilizer is applied as base fertilizer, and then 600kg / ha chemical fertilizer is applied for topdressing, wherein a topdressing method comprises the steps that 30-35 days after seedling emergence, 150kg / ha urea is applied, 225kg / ha compound fertilizer is applied in the jointing period and heading period separately, the total amount of irrigation in the growthperiod is 7,800 t / ha, the amount of film pressing water before sowing is 600 t / ha, irrigation from seedling formation to ending of the growth period is conducted 6 times, and the amount of irrigationevery time is 1,200 t / ha. By means of the method, the sugar-purpose sweet sorghum in the sand wasteland grows and develops well and has a high biological yield, soluble sugar accumulation, seed quality and yield, the water saving efficiency is high, little fertilizer is used, the economic investment is low, the water saving amount can at least reach 2,400 t / ha, and the economic benefits are far higher than those of corn planting.

The invention relates to the field of energy saving of water heaters, in particular to a water saving device for water heaters. A water-saving device for a water heater, comprising a cold water injection pipe and a hot water outlet pipe connected to the water heater, the end of the cold water injection pipe far away from the water heater is connected to the cold water inlet pipe, and the end of the hot water outlet pipe far away from the water heater One end of the mixing water pipe is connected with a mixing water pipe, and the end of the mixing water pipe far away from the hot water outlet pipe is connected with the cold water inlet pipe. , the inner outlet pipe is arranged inside the outer return pipe and is not on the same axis as the outer return pipe, and the end of the outer return pipe away from the cold water inlet pipe is connected to a terminal outlet pipe through a return device. The invention does not waste the cold water that flows out when the water heater is just turned on, and avoids the waste of water resources.
