An air passable silicone seal is on the gasket. With provision of the air passable silicone seal, a raised bottom of the air passable silicone seal contracts to close its cross-shaped opening due to water pressure in the outer water container, thereby preventing leakage.

The present disclosure is directed towards a toothbrush including a handle, a brush shaft, and a brush tip releasably connected to the brush shaft. The brush shaft includes a fluid outlet in fluid communication with a fluid source. The brush tip includes a tip outlet, one or more bristles, and one or more engagement structures to secure the brush tip to the brush shaft. The engagement structure acts to transfer motion from the brush shaft to the brush tip and defines, in part, a tip fluid passageway through the brush tip and in fluid communication with the shaft lumen of the brush shaft.

A portable oral irrigator includes: a foldable container made of a flexible material and having a bottom wall, a peripheral wall connected to the bottom wall, and a receiving space defined jointly by the bottom wall and the peripheral wall, wherein the peripheral wall is circumferentially and concavely provided with a folding groove; a main unit connected to the bottom wall and having a water inlet tube in communication with the receiving space; and a nozzle unit having a connecting tube in communication with the water inlet tube and a nozzle connected to the connecting tube. The peripheral wall can be folded, and the nozzle unit can be received in the collapsed space defined jointly by the folded peripheral wall and the bottom wall, allowing the portable oral irrigator to be carried around with ease.

A multi-purpose molar lift oral insertion and double level panorama form designed bristle brush tilter provides a thorough oral cleaning for dental and gums. The new invention is a small mechanism apparatus designed for a person with health challenges and advanced pace everyday life.

This new invention designed to help and evolve it's usage for hospital bound, preoperational, concrete operational, formal operational stages. This present invention is also designed to prevent over waste plastics going in marine ocean animals and landfills. The new invention's waste is its replaceable disposable double level panorama form designed bristle brush.

The new invention's main feature part is called the molar gap tilt lift platform. This main feature on the new invention sets in the area where a person's molar lies in the mouth. A typical oral dental jaw anatomy has its molar area in the jaw pattern. The 2nd molar are label as 2, 15, 31, 18 set and the last 3rd molar are label as 1, 16, 32, 17 which also call the wisdom teeth. This present new invention will not perform and work without the designed feature call the molar gap tilt lift platform.

The molar gap tilt lift platform feature is the main important designed to cause a gap or space between to upper and bottom jaw. Then new invention's molar gap tilt lift platform is set in its area between the upper, lower molar. And last the whole oral insertion fully enclosed in mouth. The pivot axle part along with its attached double level bristle brush can parallel on its swivel from the rotate shaft pin by oscillate or maneuver left side to right side or up and down just a touch of the fingertip.

The invention discloses a check valve, a container and an oral irrigator. The check valve is made of an elastic material and comprises a valve body part with a hollow structure, wherein an opening communicated with the hollow structure is formed in the top of the valve body part, the valve body part comprises two opposite connection walls and two opposite membranes, two opposite sides of each connection wall are respectively connected to the two membranes, the tops of the two membranes are away from each other, and the bottoms of the two membranes abut against each other. The check valve has a leakage prevention function and a ventilation function. The check valve is simple in structure, easy to machine, low in production cost, small in size, good in structural stability and long in service life and occupies a small space.

A water flosser is provided that may include a base, a reservoir positioned above the base, a lid, and a handle in fluid communication with the reservoir such as by a hose. The reservoir of the water flosser may include a recess formed in a reservoir wall for receipt of a hose support structure. An input device (e.g., a power button) may be positioned adjacent an upper portion of the water flosser, such as in or adjacent the lid. Actuation of the input device may include application of a force downward toward the base. The water flosser may include a motor having a dual output shaft, with one end of the shaft being associated with a rotary encoder or other sensing device to determine an operational characteristic of the motor. The motor may be driven by a power source such as a rechargeable battery.

The disclosure provides an easy-to-operate oral irrigator, which belongs to the field of oral cleaning and nursing. The oral irrigator comprises a water tank, a body, a power device, a control board, a nozzle, and a handle assembly, wherein the power device and the control board are disposed inside the body, the water tank and the handle assembly are disposed on the body, the body is further provided with a switch knob connected to the control board, the handle assembly is connected to the power device through a drain pipe, the nozzle is connected to the handle assembly, and the power device is used to deliver water in the water tank to the handle assembly through the drain pipe and spray it through the nozzle.

An oral cavity washing device includes a housing, a tubular storage space formed in the housing to store a liquid, and a pump housed in the housing to discharge the liquid. The housing includes a peripheral wall section constituting at least part of a peripheral wall of the storage space and having a supply port for supplying the liquid into the storage space, and a lid disposed at one end of the storage space to be able to entirely open and close a largest opening that is larger in area than any other opening in the housing.
