A number of water spray holes formed on a water spray plate is not less than 130. A diameter of the respective water spray holes is not less than 0.1 mm and not more than 0.5 mm, and an entire aperture area thereof is not more than 30 mm2. With this arrangement, since the entire aperture area of the water spray holes is reduced, it is possible to achieve water-saving effects. Moreover, since the water spray holes are small and provided by a plurality of numbers, the flow of water sprayed from the respective water spray holes is large to feel some strength hitting the skin and to achieve expansion of shower water so that the sense of using the shower may be satisfied. Moreover, since a plurality of small water spray holes is formed, a larger number of minus ion can be generated.

An ergonomic water conserving faucet assembly that pivots around a cognitive central point providing touchless water temperature, flow rate, volume control and spray pattern adjustment through multiple, hygienic means. The assembly comprises a pivotable, ergonomic, ball-shaped spout that may be used statically or hand held; a retractable water delivery hose connecting the spout to a water source; a water mixing valve at the water source delivering water of preselected temperature; solenoid valves controlling flow; proximity and object detection sensors mapping the sink area and detecting input signals; speech sensors with microphone for voice control; an LED display of water temperature; internal speakers delivering audible prompts; and an electronic controller recognizing speech and supervising operations.

The invention discloses a water-saving, uneasily blocked and automatic high pressure flush closet, which relates to the field of closets. When no person sits on the closet, a pipeline port is sealed by a closet piston and a stable sealing pipe. When a person uses the closet, tap water enters a water spray elastic rubber pipe; after the person leaves, water stored in the rubber pipe is sprayed out under triple force of restoring force of the rubber pipe and restoring force and transferred tap water pressure of the closet; the water enters a water spray inner shaft pipe from a water tank of the closet; the piston and a cylinder at the pipeline port of the closet move downwards under water pressure, and water is started to be sprayed out from a water spray hole of the cylinder; the water also flows into a pump chamber; a sandwich layer shaft pipe rotates along with an impeller; the water also enters a water spray pipeline of a closet body and an upper part of a water spray outer shaft pipe; and the water spray pipe of the closet and the water spray hole in the closet cylinder are used for rotatablely spraying the water to the inner wall of the pipeline, the water spray hole in the pipeline of the closet body is used for spraying the water to the rotating closet piston, water spray pipe and cylinder. Excrement is fed into a sewer under the action of centrifugal force and sprayed water. The closet finishes flushing.
