A water pressure driven tooth brush according to embodiments includes a hose to be connected to a faucet, a water pressure power generator to generate rotating force by receiving water pressure through the hose, and rotary tooth brush hairs rotated by the water pressure power generator. The water pressure power generator includes a cylindrical housing serving as a tooth brush handle and having a water supply pipe and a water exhaust pipe at a rear portion thereof, and at least one driving shaft at a front portion thereof, a water turbine installed in a rear chamber formed in the cylindrical housing and rotated by pressurized water, and a reduction module installed in a front chamber formed in the cylindrical housing and coupled to a rotating shaft of the water turbine to transfer reduced rotating force to the driving shaft.

Powered toothbrush systems that provide improved bristle positioning and bristle contact with tooth surfaces that reduce the time and effort required for effective brushing. Some embodiments use alternating or oscillating pneumatic pressure and suction to move a tooth brush head. Various configuration of the brush head provide different areas of coverage ranging from individual tooth to quarter mouth (U-cross section), to half (U-cross section or H-cross section) or whole mouth (U-cross section or H-cross section) coverage. Some embodiments include flexible fingers and/or bladders to keep the bristle tips properly engaged with the teeth and gums, providing bristle contact over a wide variety of malocclusion. The shape of the brush heads adapts to conform closely to the shape of the user's dental arch and to any malocclusion that may be present. The power toothbrush automatically generates motion of the brush head that simulates the “Modified Bass Method” of brushing.

The toothbrush includes a handle portion which has a disc spring assembly driven by a solenoid coil. The upper end of a central shaft which extends from the solenoid is connected to a drive flexible membrane assembly which in operation moves back and forth under the positive action of the solenoid central shaft and the return action of the spring on the central shaft. The drive membrane acts on hydraulic fluid which extends through a stem portion of the toothbrush to the brushhead, which includes a movable brushhead membrane. The moving fluid acts on the brushhead membrane to move it.

The disclosure relates to a power toothbrush or the like characterized particularly by the fact that the brush element is driven in an orbital path, as distinguished from a more conventional angularly reciprocating motion. To particular advantage, the power driven brush may be motivated by a water powered nutating action motor mounted in the handle of the unit, although alternative arrangements, including conventional electric motor units, may be used to power the device. In the preferred appliance, an orbital output motion of a nutating drive motor is converted to rotary motion, and this in turn is converted back to an orbital motion in the brush or working element. In other forms of the device, the orbital output of the nutating motor is imparted directly to the working element. The latter arrangement has advantages of greater simplicity, while the former arrangement has advantages of greater compactness.

The disclosure is directed to a flexible fluid line arrangement suited for connecting a hand held fluid-driven appliance to a source of motive fluid in a manner providing reliable, effective fluid supply, while permitting easy and facile manual manipulation of the appliance. The application specifically discloses a water driven power toothbrush adapted for connection to a household faucet. Concentrically arranged tubes connect the faucet with the hand held appliance, with the pressure side of the faucet connected to the innermost tube, while the exhaust or discharge side connects to the annular space between the inner and outer tubes. Novel, simplified swivel connections are provided between the appliance and the concentric tubes, and also between the tubes and the outlet fitting at the faucet.

The dental cleaning appliance includes an appliance body (30, 73) which has a bristle field housing (32, 52) and fluid within the housing. A flexible membrane (34) is positioned within the housing, or in a fluid-tight relationship (54) within an opening (60) in the housing. A fluid pressure system involving either a dual piston system (22, 24, 28) or a pump and valve system (70, 68, 68) provides pressure on the fluid, wherein the pistons move alternately, or the valves open and close alternately, in such a manner to produce alternating pressure above and beneath the membrane, moving the membrane and the bristle field toward and away from the teeth.

This oral cleansing device assembly is an oral hygiene tool, which is powered by compressed air pressure. My invention uses no electricity, no battery; brush-driving power is derived from a small air motor with a rechargeable small compressed air tank integrated into the handle. This invention provides lifetime functionality to a power driven dental brush since compressed air is replaceable, reusable resource. Air compressor cradle is used to recharge the small tank. The same system can be used to replace rechargeable or alkaline batteries (with limited life cycle) to power electric tooth brushes, electric razor, toy cars and many small tools cordless drills, sanders where short duration cordless use is desired. Over the life time of the product by not replacing batteries, this system is more economical, also cost of design can be reduced.
摘要:
A safe brushing is realized without sticking the gum if the bristle tips are once inserted in a pocket of a tooth by using a system having a brush of which the bristle tips automatically vibrate in a direction at right angles with the direction of length of the bristles. A brush lever 5 having a brush 4 is swingingly supported in the nozzle 1, a flow passage 3 leading to a blow-out port 1a at an end of a nozzle 1 is partly bent, and a resilient member 7 is provided at the bent portion to urge the brush lever 5 in a direction opposite to the direction of flow of water, so that the brush lever 5 oscillates reciprocally due to the resilient force produced by the resilient member 7 and the pressure of water flow, causing the bristle tips of the brush 4 to oscillate in a direction at right angles with the direction of length of the bristles outside the nozzle 1.
