Definitions
- the present invention relates to a hand-held portable, self-contained, self-powered, water-submersible water jet appliance useful for providing hydro-massage, enhanced relaxation and other therapeutic benefits.
- a second disadvantage is that, being fixed in place, such appliances cannot be conveniently used to direct their water jet towards all parts of the body.
- a person enjoying a spa for example, can, in a very limited way, adjust his or her body position so that the water jet or spray massages certain preferred areas of the body; however, because the appliance is fixed in place, it is not accessible to all areas of the person's body.
- hand-held shower heads are suitable for projecting a water stream through the air, to impinge or fall upon the human body. They are not, however, generally convenient for use under water. For example, a person sitting in a bathtub full of water could find it inconvenient to use an ordinary hand-held shower head to massage those parts of his or her body that are submerged beneath the water level. Such shower heads are generally cumbersome to move, and lack the flexibility needed to conveniently apply them to all parts of the body.
- Still another partial solution to the problem of providing massage and stimulation to a person's body are devices, such as those disclosed in the U.S. Patent No. 5,195,511 to Kodato et al., which provide a "bubble massage".
- Such devices aspirate air to produce a stream of water containing tiny bubbles.
- the air enters the unit through an air line or hose which extends outward to a chamber or the like that is placed in the open air, e.g. , outside the bathtub.
- the U.S. Patent No. 4,282,866 to Miffitt discloses still another appliance for providing a hydro-massage in a bathtub.
- This "shoebox shape” appliance is provided with a vacuum grip for attaching itself to the wall of the tub.
- the device includes a handle for carrying, it is not truly “portable” in the sense that it is intended to be held in the hand while in use.
- German DOS No. 4,004,801 discloses a hydro-massage appliance for use in the bathtub which, like the device of Miffitt, is relatively large and is designed to be attached to the wall of the tub by a suction cup.
- the principal object of the present invention is to provide a hand-held, self-contained, self- powered, water-submersible, portable water jet appliance that avoids or eliminates the problems and limitations mentioned above.
- a water jet appliance comprising, in combination, (a) an electric motor, electrically connected to and powered by a battery; (b) a water pump mechanically connected to and powered by the electric motor and having both an inlet port and an outlet port; and (c) a completely submersible housing containing and completely sealing the battery, motor and pump.
- the housing has openings for the inlet port and outlet port of the pump and, with its contents, has an external physical size and shape, as well as weight, that enable the appliance to be conveniently hand-held when in use and manipulated and transported by a person.
- the battery, motor and pump are of such capacity as to eject a water stream from the outlet port which is sufficient for substantial body massage.
- the entire apparatus may be completely submerged in water and held in the hand to direct a water stream on any desired part of the body.
- the battery is rechargeable when the apparatus is not in use.
- means may be provided to pulsate the water stream ejected from the apparatus, to adjust the water pressure and flow at the outlet port, to adjust the spread of water emerging from the outlet port and/or to provide and adjust for aeration of the water stream.
- Such means may be arranged in a suitable nozzle at the outlet port or otherwise.
- nozzles there are many nozzles that can be used in the practice of this invention. Although it is preferred to join the nozzle directly to the outlet of the pump, it is also within the scope of the present invention to join the nozzle to the outlet through a hose. In the preferred embodiment, the nozzle is joined directly to the outlet of the pump, whereby the entire appliance is moved about the body to apply water massage to desired parts of the body. When the hose is used, the person using the appliance would place the appliance in the water, and then manipulate the nozzle around the various parts of the person's body where the action of the water jet was desired.
- the appliance can be provided with a device for pulsating the water or an air/water mixture passed therethrough.
- the nozzle is preferably adjustable with respect to degree of pulsation, including a range of from no pulsation to full pulsation, and is also adjustable with respect to stream configuration so that the stream can be narrow or widely dispersed such as, for example, a spray.
- pulsating shower heads There are a variety of commercially available pulsating shower heads known in the art, and it is within the scope of the present invention to adapt such pulsating devices for use in the water-jet nozzle of the present invention.
- the nozzle may be mounted to the outlet through an adjustable mount, such as that used for a common shower head, so that the direction of the water stream from the nozzle can be varied.
- the appliance can be provided with an inlet port for air and a tube leading from the inlet port to the water pump, thereby permitting aeration of the water stream.
