ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a water purifier. More particularly, the present invention relates to an improved portable water purifier.
2. Description of the Prior Art
Drinking water is often not as pure as people would like it to be. Some people ignore the problem and drink water directly from taps. In countries where the water from the taps is not sufficiently pure, the people may suffer stomach upsets. Other people refuse to drink water from taps and they drink only bottled water. The bottled water is expensive to purchase and heavy to carry, especially when large quantities of it are required.
Known in the art of devices for purifying tap water are devices which utilize active carbon etc. to remove residual chlorine and other impurities in tap water, devices which have an additional function of adjusting the water quality, such as pH by an electrolytic treatment or by using an ion exchange resin, and also recently developed devices which utilize an infrared ray irradiation or a magnetization treatment to activate water molecules.
Numerous innovations for liquid purifiers have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.
FOR EXAMPLE, U.S. Pat. No. 5,900,143 to Dalton et al. teaches a portable container for purifying drinking water, which container comprises a body portion for containing the drinking water, a handle for lifting the container for water pouring and water refilling purposes, an ozone generator for generating ozone from air, an air pump for delivering air to the ozone generator in order to produce a mixture of air and ozone and for delivering the mixture of air and ozone to the drinking water in the body portion, and a filter for the drinking water, and the container being such that the mixture of air and ozone delivered to the drinking water in the body portion causes the drinking water and the mixture of air and ozone continuously to pass through the filter whereby the filter filters the drinking water, and the ozone purifies both the water and the filter means.
ANOTHER EXAMPLE, U.S. Pat. No. 5,891,332 to Okamoto teaches a method for purifying raw water taken from a raw water reservoir. The method includes the steps of subjecting the raw water to magnetic treatment, causing the magnetically treated water to flow through a filter medium in a first direction for purification of the treated water, and discharging the purified water into the raw water reservoir. The method further includes the steps of causing the magnetically treated water to pass through the filter medium in a second direction opposite to the first direction, and discharging the oppositely passing water into the raw water reservoir. The apparatus for realizing the above method includes a water intake assembly, a filter assembly, and a water discharge assembly. A magnetic treatment device is mounted on the water intake assembly for subjecting the raw water to magnetic treatment. A switching device is operated to cause the magnetically treated water to flow through the filter assembly selectively in the first and second directions.
STILL ANOTHER EXAMPLE, U.S. Pat. No. 5,804,068 to Reed teaches a fluid treatment device having a fluid containment housing with a first containment region and a second containment region. The first and second containment regions are connected in fluid flow communication with one another by a generally narrow, elongate transfer channel that permits fluid to flow therethrough from one containment region to another while the fluid defines a natural vortex. Moreover, a generally powerful, polarized magnet is disposed about the transfer channel in order to deliver a concentrated, polarized magnetic charge into the transfer channel, thereby acting on the fluid flowing in the natural vortex through the transfer channel and polarizing it until the fluid molecules thereof are gradually rearranged from a normal agglomerated state into a more linear, organized and substantially more permeable state that will increase a body's ability to absorb and assimilate the fluid and obtain benefits therefrom.
YET ANOTHER EXAMPLE, U.S. Pat. No. 5,628,900 to Naito teaches a water purifier that includes a filter having a cylindrical housing formed with a water inlet at one end and a water outlet at the other end and contains in the housing a ceramic layer consisting of granular ceramic heaped up in a layer, a magnetite layer consisting of broken pieces of magnetite heaped up in a layer and provided at least above or below the ceramic layer, and annular magnets provided above and below the ceramic layer in such a manner that these annular magnets coincide with each other in the sense of magnetic lines of force and that the direction of the magnetic lines of force is parallel to the direction of flow of water. Water molecules are activated while passing through the magnetic field produced by the annular magnets and the magnetite layers which are magnetized by the annular magnets.
STILL YET ANOTHER EXAMPLE, U.S. Pat. No. 5,556,654 to Fregeau teaches a method of treating consumable liquids, the liquids so produced, and an assembly for practicing the method. Consumable liquid is passed through a magnetic field having properties effective to enhance the flavor of the liquid, the field preferably being established by a permanent magnet establishing a continuous polarity on opposite sides of the liquid with a minimum magnetic field strength of about 3000 Gauss. The assembly for treating the liquids may include first and second tubular permanent magnets having opposite radially spaced first and second pole portions of opposite polarity, a pair of pole pieces received between the pole portions, and in encasement for maintaining the magnets and pole pieces together so that a fluid flow path is defined through the magnets and a predetermined gap established by the pole pieces, and so that the pole portions of the same polarity for each magnet are on the same side of the flow path.
It is apparent that numerous innovations for liquid purifiers have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described.
SUMMARY OF THE INVENTION
ACCORDINGLY, AN OBJECT of the present invention is to provide an improved portable water purifier that avoids the disadvantages of the prior art.
ANOTHER OBJECT of the present invention is to provide an improved portable water purifier that is simple and inexpensive to manufacture.
STILL ANOTHER OBJECT of the present invention is to provide an improved portable water purifier that is simple to use.
BRIEFLY STATED, YET ANOTHER OBJECT of the present invention is to provide an improved portable water purifier of a type having a pitcher with a lower terminal wall and being divided vertically by a lateral partition into an upper compartment for holding raw water and a lower compartment for holding purified water, and a filter depending from the lateral partition into the lower compartment for purifying the raw water into the purified water. The improvement includes a base having a weight and replaceably supporting the pitcher thereon and acting as a coaster therefore, and a permanent magnet having a weight and encased throughout the base for delivering a concentrated and polarized magnetic charge through the lower terminal wall of the pitcher and into the purified water so to polarize the purified water until its molecules are gradually rearranged from a normal agglomerated state into a more linear, organized, and substantially more permeable state that increases a body's ability to absorb and assimilate the purified water and obtain benefits therefrom, with the base providing triple duty as a support and coaster for the pitcher and as an
