An oral irrigator contains: a body, a water tank and a detachable jet tip which are both in connection with the body, a power device and a control device Which are both accommodated in the body. The power device is configured to deliver water from the water tank to the detachable jet tip. The power device includes a first outlet defined thereon and configured to discharge the water, a delivery tube connecting with the first outlet, and a first seal element configured to stop water flowing into the body from the power device so that the water discharges out of the first outlet.

The present invention describes a method for a U-shaped teeth brush device having a conformable shape adjusting U-shaped teethbrush module and one or more individual tooth brushes coupled to the power drive mechanism, each brush having a sensor, piezoelectric crystal and transducer and each tooth brush having a block anchor coupled to the power drive, under smart controls, an electronic control system for sensing individual tooth pressure and controlling motor transmission of vibration to prior positioned brushes, whereby a users unique mouth features can be accounted for by adjusting U-shape distal ends to fit through the users mouth and align with users teeth arch for programmatically brushing more than one tooth simultaneously.

The present application discloses an oral irrigator nozzle, which comprises a nozzle, a bending part, a connector and a mixed-flow nozzle located at the lower end of the nozzle, wherein the mixed-flow nozzle is provided with a shell, and an inner cavity, wherein the inner cavity is provided with a conical through hole along the water flow direction; the conical head of the conical through hole is connected with an inverted conical through hole; the junction of the conical through hole and the inverted conical through hole forms a throat cavity; the throat cavity is provided with a through hole penetrating the throat cavity; and the end of the through hole is provided with external counterbore. The water jet from the nozzle of the present application can form a cavitation effect, and the water jet contains microbubbles and carries a large amount of air, so that the cleaning power of the water jet can be enhanced after the water jet reaches the teeth, and at the same time, the water jet produces a scattering effect. Compared with single water flow, it is less irritating to gums, less likely to cause gum bleeding and pain, and the cleaning area is larger than that of single water flow. At the same time, the same water pressure can be achieved by using less pump power.

Showerhead devices incorporate sensors to control bath fill levels. Showerheads have interchangeable attachments, including bristle attachments. Oral care devices are attachable to standard shower arms. Pump devices allow various lotions and fluids to be used in conjunction with showers. Shower organizing devices provide for ordered storage and access to accessories. Bathtub spouts including sensors and valves to control bathtub filled levels.

An oral rinsing apparatus that washes away plaque, bacteria, and food debris that might reside on the teeth and along the gumline includes a handle, a nozzle, and a water supply line. The handle is adjacently attached to the nozzle. The water supply line that is connected to the handle and positioned opposite to the nozzle. The water supply line is in fluid communication with an existing water source diverter and provides a stream of water into the handle and the nozzle. The stream of water then flows through a first channel of the handle and a second channel of the nozzle before discharges through a head of the nozzle. A flow-activation button of the handle turns on and off the stream of water that exits through the head as a plurality of flow control settings are integrated into the head.

A showerhead adapter is disclosed which can be used with presently available commercial showerheads which allows multiple activities while showering. These activities include being able to cleanse the face, clean one's fingernails, clean one's feet, shave, clean one's teeth, and clean the shower area.

A compact oral hygiene device comprises a unique mini constant jet pump which integrated with a motor, has three diaphragm chambers, draws the fluid from a reservoir and propels fluid out from a buffer room to tips at constant pulseless, high efficiencies and low noise; and a plurality of exchangeable tips cleanses teeth and the interdental area.

A shower head contains: a body, a showering assembly, a switch button, a shift assembly, and a flushing pipe. The body includes a handle, a head portion, an inlet segment, a water supply chamber, an outlet segment, a tab, and a notch. The showering assembly is connected with the water supply chamber. The switch button includes two locking extensions. The shift assembly includes a water distribution projection which has a central orifice, a coupling portion, and a hemispherical rubber ring. The movable seat has a first conduit and an actuated element. The movable seat has a water guider and a spherical abutting face. The flushing pipe includes a channel, and an end of the flushing pipe is connected on a top of the central orifice of the water distribution projection. The flushing pipe includes a washing segment and a spray nozzle.
