Abstract: The present invention provides a sanitary automatic water leakage detection and shut-off apparatus installed between a water controlling unit and a water outgoing unit and comprising a water controller, an accumulating unit and a detecting unit; wherein the water controlling unit comprises an inlet, an outlet and a solenoid valve. The solenoid valve is a normally-open solenoid valve capable of closing the outlet to stop water from going out. The accumulating unit is mounted between the water controlling unit and the water outgoing unit and comprises an accumulating hole adjacent to a bottom thereof. The detecting unit is installed on the accumulating unit and electrically connected to the solenoid valve. The detecting unit activates the solenoid valve via an electronic communication method based on a leakage status of the accumulating unit to shut off the water outlet of the water controlling unit and to stop water supply thereof immediately.

Abstract: An air-guiding device is used in an intake manifold arranged between an internal combustor and an air-filtering device. The air-guiding device is a tubular element made of a flexible metal sheet and includes a positioning section and an air-guiding section. The positioning section is fit in the intake manifold. The air-guiding section includes helical blades that converge as they extend from the positioning section.

Abstract: An anus-washing apparatus includes a valve housing, a valve, a raising unit, and a sprayer. The valve housing includes a hot water inlet pipe, a cold water inlet pipe and an outlet pipe. The valve is inserted in the valve housing for opening and closing the hot and cold water inlet pipes. The raising unit is connected to the outlet pipe. The sprayer includes a hollow axle pivotally connected to the raising unit, a pivotal pipe extending from the hollow axle, and an extensible pipe with an end telescopically inserted in the pivotal pipe and another end defining apertures. The valve is operable to let water into the raising unit to raise the pivotal pipe and extend the extensible pipe to move the apertures from the pivotal pipe to spray water.
