ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a water filtering system having a general filtering means, a ceramic filtering means, an activated carbon filtering means and a magnetic member filtering means.
BACKGROUND OF THE INVENTION
A conventional water treatment system generally includes a casing in which a plurality of filtering devices are received and the filtering devices are connected with each other by pipes. An inlet pipe is connected to the first filtering device and an outlet pipe is connected to the final filtering device. Water flows in the first filtering device from the inlet pipe and flows out from the outlet pipe. Particles in the water are retained in the filtering devices while flowing through the filtering devices so that the water is treated. However, only large particles in the water can be removed from the water in the conventional water treatment system. Another type of water filtering system employs a film having tiny holes and the water to be purified is forced to pass the film. The water is called pure water after passing through the film. Nevertheless, the tiny holes are so small that mineral elements in the water are removed from the water and the mineral elements are good for people's health.
The present invention intends to provide a water filtering system that maintains mineral elements in the water and activates the water by magnetic members.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a water filtering system and comprising a first filtering device which is connected to a fluid volume meter. A second filtering device has a ceramic tube received therein and a first end of the second filtering device is connected to the fluid volume meter and a third filtering device has an inlet connected to a second end of the second filtering device. Activated carbon particles are received in the third filtering device and an outlet of the third filtering device is connected to a fourth filtering device. The fourth filtering device has an inlet defined in a first end thereof and an outlet is defined in a second end of the fourth filtering device. A plurality of units are received in the fourth filtering device and the units each have a first end which is an open end, and a second end having a plate connected thereto. Each plate has an aperture so that the plate of one unit is engaged with the open end of an adjacent unit. An inlet of the fourth filtering device communicates with the aperture of the plate of one unit adjacent to the inlet of the fourth filtering device. Each unit has two separate boards to define three partitions and two of the three partitions respectively receive a magnetic member therein. The two magnetic members are separated by a middle partition of the three partitions. A final filtering box is received in the fourth filtering device and located adjacent to the outlet of the fourth filtering device.
The primary object of the present invention is to provide a water filtering system wherein magnetic members are used in a filtering device in the system to magnetize the water so that the water carries more oxygen.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
