  • Patent number: 8776824
    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.

  • Publication number: 20120305457
    Abstract: A water filter and alert assembly for bathroom use includes a housing, at least one filter element, an alert device, and a cap. The housing has an externally threaded end, an internally threaded end, and a water passageway. The at least one filter element is disposed in the water passageway. The alert device includes a temperature sensing element and a temperature indicating element, wherein the temperature sensing element is provided in the water passageway to sense water temperature, and the temperature indicating element is configured to show water temperature and alert messages. The cap has an externally threaded end and an internally threaded end. The internally threaded end of the cap is connected with the externally threaded end of the housing so as to guide outgoing water and retain the at least one filter element.

  • Patent number: 8296872
    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.

  • Publication number: 20080201836
    Abstract: An adjustable water-spraying device for a user to clean themselves after relieving themselves includes a base, a first control valve, a second control valve and at least a water-spraying unit. The base includes a first space and a second space communicating with each other. The first control valve is set in the first space to control the water temperature, and the second control valve is set in the second space. The water-spraying unit is attached in a water outlet of the base, and extended into toilet seat unit. Thus, the second control valve determines the opening or closing water outlet to drive one of the water-spraying units to spurt water and clean the users' anus.
