  • Patent number: 8985483
    Abstract: Disclosed is a method and device to control a spray pattern produced from a spraying device consisting of a plurality of individual jets that form the resulting spray pattern. The trajectory of each individual jet is controlled by orienting the nozzle-like feature that produces each individual jet, thereby producing a variety of spray patterns. This is accomplished utilizing the flexible properties of elastomeric or rubber-like materials. In addition to allowing for deformation or movement to remove possible obstructions to the fluid flow, this flexibility property also permits for specific, controlled movements, whereby it is possible to control the trajectory of the fluid issuing from the device. These rubber-like materials can include specific features that allow the material to be deformed in a controlled fashion so as to predictably control the trajectory of the streams issuing from the individual nozzles.

  • Patent number: 8479772
    Abstract: A diverter valve receives fluid from an inlet port. A camshaft is rotated within a housing to slide a cam follower along an axis to regulate fluid flow to an outlet port when the camshaft is rotated. The housing provides an inlet port and first and second outlet ports. The camshaft includes a cam lobe that is offset relative to a rotational axis of the camshaft. The cam follower is supported on the cam lobe and is movable along a longitudinal axis to selectively block at least one of the first and second ports. In one embodiment, first and second cam followers are used to selectively block outlet ports that are arranged approximately 90 degrees from one another. The first and second cam followers move in first and second directions transverse to one another. In another embodiment, a single cam follower is used to regulate flow through two outlet ports that are arranged approximately 180 degrees from one another.

  • Patent number: 8104697
    Abstract: Disclosed is a method and device for fluid handling relating to controlling and directing the water streams from spray devices utilizing multiple liquid streams to produce an effluent that enhances a user's perception of spray performance. In the disclosed embodiments, a cavity acts as a mixing chamber for multiple fluid jets that enter the cavity at various locations, angles and flow rates. By positioning these inlet ports in the upper portion of the cavity, and with the ability to precisely direct and meter the fluid flow, the spray device may achieve a multitude of flow patterns from an outlet.

  • Patent number: 8066204
    Abstract: A shower assembly is provided that includes a shower head having an integrated diverter valve. The shower head receives a detachable hand-held shower wand. The diverter valve is arranged upstream of an adjustable connector so that length is not added to the shower assembly that would interfere with headroom. A cam shaft of the diverter valve is rotated to selectively control fluid flow between the shower head and the hand-held shower wand. Cam followers are moved linearly in response to rotation of the cam shaft to selectively block first and second outlet ports.

  • Patent number: 6715699
    Abstract: The showerhead engine assemblies provide different combinations and variations of continuous, deflected, pulsating sprays, and aeration spray patterns including those that are adjustable enabling wide variations in the degree of aeration of the water passing through the showerhead, enabling wide variation of the characteristics of the water spray patterns. The spray patterns include a nondeflected, nonpulsating spray pattern; a deflected nonpulsating spray pattern; a nondeflected, pulsating spray pattern; and a deflected, pulsating spray pattern, while enabling the engine assembly to be self-cleaning. For pulsating spray modes, the showerhead engine assembly includes but five plastic parts and an O-ring seal; the parts being a stator, a spinner, an engager, a pressure plate, and a faceplate, openings beings disposed in the pressure plate and faceplate to enable fluid flow therefrom. Deflecting surfaces on the faceplate enable a variety of different flow patterns.

  • Patent number: 6311734
    Abstract: The showerhead security cover prevents unauthorized access to a connector of a shower assembly. The connector secures the showerhead to the shower arm, the connector, showerhead, and shower arm being standard without any modification required. The showerhead security cover comprises a housing and a lock. The lock is integral with the housing. Once the lock is engaged, the housing encases the connector and prevents access to the connector. Once the lock is engaged, there is no substantial rotational movement of the connector relative to the shower arm. One end wall of the housing seats against an end of the connector during engagement preventing any substantial axial movement of the connector relative to the connector. The housing is strong enough to prevent engagement with the connector even when the housing is grasped with pliers. Disengagement is enabled by the use of a special tool to allow authorized access to the connector.

  • Patent number: 5114570
    Abstract: A water filter cartridge has a cylindrical shell. A conduit runs between closing end walls and is disposed within a filtration material. There are additional openings in the respective end walls for communicating the flow of water through the material. A water filtration element of a porous medium is shaped to nest within a portion of the shell encircling a corresponding portion of the filtration material and defining space between the medium and the inner side wall of the shell with that space being in the water flow path from one of the end walls and the material through the medium. A reference color is exhibited over a portion of the exterior side wall of the shell adjacent to the location of the medium inside the shell, and the medium exhibits a given color upon beginning of usage but changes color with continued usage in response to its entrapment of matter in the water. The shell is transparent over the medium to enable the user to compare the medium color to the reference color.

  • Patent number: 4958629
    Abstract: The housing of an oral hygiene device is attachable to a water faucet. A regulator within the housing responds to the water which is subject to pressure variation. The regulator accommodates that variation in developing automatically a stream of water at a constant pressure. A turbine within the housing is caused to rotate in response to energy in the stream. A piston pump draws water deflected by impellers on the turbine and forms that water into a series of pulses. A flexible hose coupled to the housing includes a handle for directing the pulses against the teeth and gums of a user at a desired pressure.

  • Patent number: 4374354
    Abstract: An electric toothbrush housing contains a motor, a battery and a secondary coil coupled to charge the battery. An elongated magnetic core is disposed within that secondary coil. A well is defined in a base which receives a portion of the housing within which the secondary coil is positioned. In that base is a primary coil for inducing magnetic energy into the secondary coil. Disposed within the primary coil is an elongated stud of magnetic material. It is aligned axially with the core, so that respective end portions are mutually adjacent. One of those end portions is generally cup shaped and the other is formed and relatively oriented to nest within the first.

  • Patent number: 4187986
    Abstract: A sprayer has a hollow housing with an inlet port and an outlet opening. A cap assembly closes the outlet opening and includes a plurality of sets of discharge orifices with each set exhibiting an individually different characteristic of orifice flow of fluid from the housing interior. The orifice sets are selectively opened to the passage of flow out of the housing and that flow is valved. Different sets of the orifices provide for a fine-spray cone, larger streams and a swirling jet. A porting seal cooperates with a selector plate to enable fluid communication to different sets of orifices and an overall valving assembly also is included. Still further is a stand for the sprayer which supports it, when desired, above a holder or in a manner which enables convenient storage.
