The invention discloses a water toothpick, which includes a high-pressure gas generator, a water tank, a valve, a nozzle assembly and a water supply, wherein the high-pressure gas generator is communicated with the nozzle assembly, the valve is arranged between the high-pressure gas generator and the nozzle assembly, and the water supply is respectively communicated with the water tank and the nozzle assembly, so as to convey water in the water tank to the nozzle assembly. When the water toothpick is used, the high-pressure gas generator transmits generated high-pressure gas to the valve, and after a certain amount of water is stored in the nozzle assembly, the valve is opened, and the high-pressure gas at the valve is instantaneously discharged into the nozzle assembly, mixed with the water in the nozzle assembly to form compressed vapor, and then sprayed out from the nozzle assembly to complete one cleaning action.

A massage accessory for use with an electric toothbrush has a body and a coupling mechanism. The electric toothbrush has a body, and a shaft configured to generate an oscillating movement. The coupling mechanism is configured to couple the massage accessory to the shaft of the electric toothbrush. The body of the accessory has a base at a proximal end of the body, a head at or near a distal end of the body, and a flexible region between the base and the head. The base, the head, and the flexible region are arranged such that the head is configured to move in response to the oscillating movement of the shaft and the base remains relatively stationary compared to the body of the electric toothbrush. A massage accessory for use with an electric toothbrush has a transfer shaft with a driving feature, and a coupling mechanism configured to couple the massage accessory to the shaft of the electric toothbrush. The accessory has a head having a driving feature that is complementary to the driving feature of the transfer shaft. A space is provided between the driving feature of the transfer shaft and the driving feature of the head when the transfer shaft and head are engaged such that oscillating movement of the transfer shaft causes a corresponding oscillating movement of the head and additionally causes vibration of the head.

Disclosed is a portable teeth cleaning apparatus, which implements, through a pump in a teeth cleaner, a function of supplementing a teeth cleaning liquid from a connecting seat connected to the teeth cleaner. Therefore, it is no longer necessary to connect the teeth cleaner to a teeth cleaning liquid source through a connecting hose during teeth cleaning, and liquid leakage is avoided during liquid supplement. Further, a seating/unseating status and whether a liquid reservoir is filled up are detected automatically, and a controller controls on/off and switching of a series of valves, thereby implementing automatic liquid supplement of the teeth cleaner.

The present disclosure discloses a water flosser comprises a housing, a tooth irrigation portion, a water nozzle portion, a winding mechanism, and a water pipe configured to be bent and wound. The tooth irrigation portion is disposed in the housing and comprises a water inlet and a water outlet. The water nozzle portion is in communication with the water outlet of the tooth irrigation portion.

An oral irrigator including a reservoir, a handle, a housing, a bezel positioned at least partially within and secured to the housing, and an actuator operably coupled to the housing and movable relative thereto is disclosed. The actuator includes a control shaft extending from the interior surface of the face and positioned inwards from an outer perimeter of front wall. The control shaft extends through an aperture in the housing and movement of a gripping body causes the control shaft to directly actuate a switch or a pressure assembly positioned within the housing. The actuator also includes an augmentation fluid positioned between the bezel and a portion of the actuator. The augmentation fluid modifies a frictional relationship between the bezel and the actuator to provide a predefined resistance force between the actuator and the bezel as the actuator is rotated relative to the bezel.

An electric massage instrument can efficiently and easily control ultrasonic vibration function and infrared irradiation function to be simultaneously applied to a desired part. A single circuit board on which an electronic circuit having an ultrasonic vibration function and an infrared irradiation function is arranged in a gripping part gripped by hand, and irradiation parts of the infrared radiation function are provided on the contact part side of the tip end arranged to extend the circuit board. A housing forming a gripping part and a contact part is a single continuous housing made of synthetic resin, and the single circuit board extending to the tip end is fitted and fixed.

There is provided a tactile sensory device for use by a baby or child. The tactile sensory device comprises a pulsation actuator configured to, in use, produce a mechanical vibration having a pulsatile waveform that is the same, or substantially the same as, a pulsatile waveform of blood flowing in an umbilical cord.

A vibrating teething device includes a silicon outer shell that is larger than a human mouth and having protrusions that can fit within a human infant mouth; a battery powered vibrator encased within an open cavity in the silicon outer shell; and a cap fastened over the open cavity.

The oral irrigation/liquid delivery device provides flow controlled fluid to body areas specifically the mouth, or parts of body or other non-body areas via pump device or connection to water source through a wand handle with bulbous smooth head with multiple openings/orifices for the fluid to flow to ensure that no high-pressure jets result (unless within the design) and can be used in confined area; idea for irrigating or rinsing the mouth after jaw surgery or other situation where it is not possible or recommended to use a high-pressure “water pick” type of device; allows user who may have a problem sucking in water to rinse to have fluids safely delivered to mouth to clear and clean it; allows for the delivery of medicated and or other liquid delivery of water or any other liquid to rinse or even imbibe; said device could also deliver feeding fluids; optional connection via any pump or faucet diverter system to delivery fluids, including option to have a siphon mix of one solution along with another with the secondary solution being introduced to the flow as a result of the pump mechanism or a siphon mechanism based upon the flow of a fluid that is the primary solution. Optionally, a rubber or other suitable tube or hose may be connected between the wand and the tip/connecting point to the pump or fluid delivery device. The same device or its components could be incorporated into other devices such as water bottles or syringe ends.
