Abstract:
A brush head for an oral cleansing device is provided. The brush head including a hollow shaft and a cantilevered beam positioned within the shaft. The cantilevered beam is configured to press against a drive shaft of the oral cleansing device to transfer a rotational motion of the drive shaft to the brush head. The cantilevered beam can also be formed on an adapter secured within the shaft.
Abstract:
The present disclosure relates generally to oral health products, such as electric toothbrushes. In one example, the electric toothbrush includes a housing, an output shaft positioned within and extending out of the housing, a magnetic assembly positioned within the housing and configured to impart an oscillation motion to the output shaft, and a spring positioned within the housing. The spring includes a first end non-rotatably coupled to the housing and a second end non-rotatably coupled to the output shaft, such that the spring twists as the magnetic assembly oscillates the output shaft to amplify the oscillation motion of the output shaft generated by the magnetic assembly.
Abstract:
A water flosser is provided that may include a body, a reservoir, a cap coupled to the body and a tip extending through an opening in the cap. The water flosser may include a latch assembly that selectively retains the tip to the body. In one embodiment, the cap, the tip and the latch assembly are all rotatable as a unit about a defined axis relative to the body. An ejector button may be provided to actuate the latch assembly. In one embodiment, the ejector button extends through an upper surface of the cap. Actuation of the latch assembly may include displacement of the ejector button in a direction that is parallel with a rotational axis of the tip. In some embodiments, the reservoir of a water flosser includes a tapering volumetric section that concentrates a volume of fluid about an inlet of a tube coupled with a pump.
Abstract:
A showerhead may include a first plenum in fluid communication with a first group of nozzles, a second plenum in fluid communication with a second group of nozzles, and a water direction assembly in fluid communication with the first plenum, the second plenum, and a fluid inlet, and alternatingly fluidly connecting the first plenum and the second plenum with the fluid inlet. The water direction assembly may include a turbine and a shutter arranged to oscillate between positions, oscillation of the shutter alternatingly fluidly connecting the first and second plenums with the fluid inlet.
Abstract:
An oral irrigator handle through which fluid flows to a tip is described. Fluid flows from a fluidically connected hose to the tip during irrigate mode, and fluid flow may be interrupted by selecting a pause mode. The handle includes a mechanically controlled actuator for selecting the pause mode. The actuator may be operably connected to a shuttle valve that is positioned to block fluid flow to the tip during pause mode but not during irrigate mode. The handle may also include a swivel assembly. The swivel assembly prevents rotational movement of either the handle or the hose from being transmitted to the other, such that rotation of the handle will not affect the position of the hose.
Abstract:
The present disclosure includes embodiments directed to an oral irrigator with a magnetic attachment. The oral irrigator may include a base unit and a handle. The base unit may include a first positioning feature. The handle may include a second positioning feature corresponding with the first positioning feature of the base unit to removably couple the handle to the base unit at any one of a plurality of desired positions, such as at any one of a plurality of vertically adjacent positions, relative to the base unit. Each of the first and second positioning features may be a magnet device to magnetically couple the handle to the base unit The magnetic attachment between the handle and the base unit may automatically align the handle into a correct storage position.
Abstract:
A brushing device including a motor having an eccentric drive shaft, an output shaft operably connected to the motor, and a power train assembly coupled between the eccentric drive shaft and the output shaft. The power train converts rotation of the eccentric drive shaft into an oscillating movement of the output shaft. The power train includes one or more conservation features that absorb energy when the output shaft rotates in a first direction and reapply energy to the output shaft when it rotates in a second direction.
Abstract:
An irrigating device (100) including a massage mode module in communication with a motor driving a pump (119). During a normal mode the pump has a first pulse rate and during massage mode the massage mode module provides a massage control signal to the motor to cause the pump to have a second pulse rate. In other embodiments, the disclosure includes an oral irrigator including a base (102) and a reservoir (104) removably connected to the base (102). The oral irrigator further includes a prow (103) operably connected to the base (102) and extending vertically upwards from the base (102). The prow (103) may extend in a similar direction as sidewalls of the reservoir. The oral irrigator further includes a lid (120) rotatably connected to the prow (103). The lid (120) rotates between a first position where a fluid cavity of the reservoir (104) is exposed to a second position where the lid (120) covers at least a portion of the fluid cavity.
Abstract:
A oral irrigator tip for an oral irrigator. The oral irrigator tip may include a shaft portion with a base, an apex, and a transitional portion linking the base to the apex. The shaft portion may be straight or angled. The shaft portion may be hollow from the base to the apex to define a fluid passage, thus permitting fluid to flow along the shaft portion. A retaining feature may be formed on the shaft portion to facilitate retention of the oral irrigator tip by an oral irrigator. A connector may join a nozzle to the shaft portion. Attached to the connector may be a bristle element, which may include multiple individual bristles glued or otherwise affixed to the connector. The bristles may be arranged in a circular pattern; water may flow around the individual bristles or through the center of the bristles.
Abstract:
A handheld showerhead with a showerhead portion and a handle portion. The showerhead portion may include at least two fluid channels. The handle portion may be operatively associated with the shower portion. The handle portion may include at least one fluid inlet or fluid passage. The handle portion may further include a movable mode selector. Movement of the mode selector may selectively place the fluid inlet or fluid passage in fluid communication with at least one of the two fluid channels in the showerhead portion.
