Abstract

An electrical water filter device includes a plurality of porous electrodes and one or more porous separators. Each of the one or more porous separators is interposed between two adjacent porous electrodes. A respective porous electrode includes a connection portion extending outside an edge of a porous separators next to the respective porous electrode.

Claims (28)

1. An electrical water filter device, comprising:

a plurality of porous electrodes;

one or more porous separators, each of the one or more porous separators being interposed between two adjacent porous electrodes; and

a case surrounding the porous electrodes and the one or more porous separators to fix the porous electrodes and the one or more porous separators in the case, wherein the case includes an upper portion to receive water, a lower portion to dispense the water, and a sealing member interposed between the upper portion and the lower portion,

wherein each of the porous electrodes includes a connection portion extending outside an edge of the one or more separators,

wherein the case includes an electric connector having a first end portion extending from an inner surface of the case to an inside of the case where the porous electrodes and the one or more porous separators are disposed and a second end portion extending from an external surface of the case to an outside of the case, wherein the electric connector is connected to the connection portions of the porous electrodes,

wherein the upper portion includes a base portion, a first protruding portion protruding from the base portion toward the lower portion, and a second protruding portion protruding from the based portion toward the lower portion, wherein a height of the second protruding portion is greater than a height of the first protruding portion, and

wherein when the upper portion and the lower portion are engaged to and in contact with each other, the first protruding portion presses against the sealing member and the second protruding portion presses against one of the porous electrodes and the one or more porous separators.

2. The electrical water filter device of claim 1 , wherein the first end portion of the electric connector is extended in a first direction, and the second end portion of the electric connector is extended in a second direction different from the first portion.

3. The electrical water filter device of claim 2 , wherein at least one of the upper portion or the lower portion includes a port to receive at least one of the connection portions of the porous electrodes and the electric connector of the case.

4. The electrical water filter device of claim 3 , wherein the upper portion and the lower portion include a fastening mechanism to fasten each other together.

5. The electrical water filter device of claim 4 , wherein the fastening mechanism includes threads on the upper portion and the lower portion.

6. The electrical water filter device of claim 4 , wherein the fastening mechanism includes one or more snap buckles and one or more buckle receivers to engage the upper portion to the lower portion.

7. The electrical water filter device of claim 3 , wherein each of the upper portion and the lower portion includes a plurality of through holes to allow water to flow through.

8. The electrical water filter device of claim 7 , wherein the upper portion of the case includes a wall extending upward to receive the water.

9. An electrical water filter device comprising:

a plurality of porous electrodes;

one or more porous separators, each of the one or more porous separators being interposed between two adjacent porous electrodes; and

a case surrounding the porous electrodes and the one or more porous separators to fix the porous electrodes and the one or more porous separators in the case, wherein the case includes an upper portion to receive water, a lower portion to dispense the water, and a sealing member interposed between the upper portion and the lower portion,

wherein each of the porous electrodes includes a connection portion extending outside an edge of the one or more porous separators;

wherein at least one of the connection portions of the porous electrodes extends outside of the case;

wherein the upper portion includes a base portion, a first protruding portion protruding from the base portion toward the lower portion, and a second protruding portion protruding from the based portion toward the lower portion, wherein a height of the second protruding portion is greater than a height of the first protruding portion; and

wherein when the upper portion and the lower portion are engaged to and in contact with each other, the first protruding portion presses against the sealing member and the second protruding portion presses against one of the porous electrodes and the one or more porous separators.

10. The electrical water filter device of claim 9 , wherein the connection portions of the porous electrodes have a thickness less than other portions of the porous electrodes.

11. The electrical water filter device of claim 9 , wherein at least two connection portions of the porous electrodes are connected to each other within the side wall of the case.

12. The electrical water filter device of claim 9 , wherein the connection portions of the porous electrodes are separated by a material of the case.

13. The electrical water filter device of claim 9 , wherein each of the upper portion and the lower portion includes a plurality of through holes to allow the water to flow through.

14. The electrical water filter device of claim 13 , wherein the upper portion includes a wall extending upward to receive the water.
