    Abstract: A portable vibrating bidet is a portable, cylindrical device with a telescoping hose that allows the user to deliver cleansing liquid and air to clean themselves after using the restroom. Cleansing liquid is drawn from a liquid reservoir by a pump to a spray nozzle of the telescoping hose, and air is drawn from a plurality of air vents to the spray nozzle by a fan. The telescoping hose extends from and retracts into a hose cavity in the cylindrical body and is covered when not in use by a cap that uses an ultra-violet light source to sterilize the telescoping hose after use. A heater controls the temperature of the dispensed fluid. A vibrator delivers vibrations through the cylindrical body and cap for added functionality as a pleasure device. A plurality of exterior controls allows the user to control the various functions of the portable vibrating bidet.

    Abstract: This invention comprises a bidet device, including a bidet kit, that can be mounted on a conventional toilet seat. A bidet valve is positioned between a bidet hoop conduit and a water supply conduit. Rotation of the bidet hoop conduit results in rotation of a valve seat relative to a valve stem to permit water to flow through the bidet hoop conduit. Water does not initially flow and only flows as the bidet hoop conduit reaches an extended operative position. Rotation of a handle or lever arm is the only movement necessary to move the bidet hoop conduit and initiate actuation of the valve. The bidet valve includes an actuator with a notch, the sides of which engage a stationary arm attached to the toilet seat to open and close the valve.

    Abstract: A sanitary washing apparatus includes: a washing nozzle; and a pressurizing device. The sanitary washing apparatus that performs first and second jetting processes alternately jetted with a prescribed waiting time there between. The pressurizing device makes minimum pressure of water in the second jetting process higher than minimum pressure of water in the first jetting process and makes maximum pressure of water in the second jetting process higher than maximum pressure of water in the first jetting process so that the second water mass is faster than the first water mass. The prescribed waiting time between the first and the second jetting processes is set so that before the first water mass impinges on the human body, the second water mass having faster velocity than the first water mass overtakes the first water mass to enlarge jetting water cross-sectional area of the first water mass.
