It is to be noted that, when the functions of conventional elements and the detailed description of elements related with the present invention may make the gist of the present invention unclear, a detailed description of those elements will be omitted. In addition, it should be understood that the shape and size of the elements shown in the drawings may be exaggeratedly drawn to provide an easily understood description of the structure of the present invention.

(15) As shown in FIGS. 1 to 5, a water electrolytic cell 10 included in an oxygen generator integrated with the ozone removal filter of an embodiment of the present invention roughly includes a container body 100 provided in a form of a container and containing mineral water therein, a detachable upper cover 200 coupled to a upper portion of the container body 100 as a detachable form to seal, and provided with a water supply hole 201 supplying mineral water therethrough and an oxygen discharge hole 202 and a level sensor 203 controlling to maintain a constant level of mineral water all the time by measuring a level of mineral water supplied to the container body 100, and a lower body 300 coupled to a lower portion of the container body 100 to seal, provided with a positive electrode plate 302 disposed on a diaphragm 301 and a negative electrode plate 303 disposed below the diaphragm 301 separately, and provided with a hydrogen discharge hole 304 in one side thereof.

(16) The most characteristic feature is that the filter mounting portion 210 provided with the through hole 210a is integrally provided in the oxygen discharge opening, which communicates with the oxygen discharge hole 202, of the detachable upper cover 200 sealing the upper part of the container body 100. An ozone removal filter 230 is seated in the filter mounting portion 210 and a cap body 220 covers an upper portion of the filter mounting portion 210 such that the ozone removal filter 230 is provided in the water electrolytic cell 10.

(17) As shown in FIGS. 6 to 10, an oxygen generator integrated with the ozone removal filter according to another embodiment of the present invention roughly includes a container body 100 provided in a form of a container and provided with an integrated upper cover 200, which is provided with a water supply hole 201 supplying mineral water therethrough and an oxygen discharge hole 202 and a level sensor 203 controlling to maintain a constant level of mineral water all the time by measuring a level of mineral water supplied to the container body 100, and a lower body 300 coupled to a lower portion of the container body 100 to seal, provided with a positive electrode plate 302 disposed on a diaphragm 301 and a negative electrode plate 303 disposed below the diaphragm 301 separately by using a separate electrode plate connecting structure 310, and provided with a hydrogen discharge hole 304 in one side thereof.

(18) That is, differences between the first embodiment and the second embodiment are that the upper cover 200 provided with the water supply hole 201 supplying mineral water therethrough, the oxygen discharge hole 202, and the level sensor 203 controlling to maintain the constant level of mineral water all the time by measuring the level of mineral water supplied to the container body 100 is integrally formed on the upper portion of the container body 100 provided with the container shape, and the positive electrode plate 302 is disposed on a diaphragm 301 and the negative electrode plate 303 is disposed below the diaphragm 301 separately at the lower portion of the lower body 300 coupled to the lower portion of the container body 100 by using the separate electrode plate connecting structure 310.

(19) However, the second embodiment of the present invention has same characteristic feature of the first embodiment, in which the filter mounting portion 210 provided with the through hole 210a is integrally formed at the integrated upper cover 200 sealing the upper part of the container body 100 at a position corresponding to the oxygen discharge hole 202 communicating with the oxygen discharge opening of the detachable upper cover 200, the ozone removal filter 230 is seated in the filter mounting portion 210, and a cap body 220 covers the upper portion of the filter mounting portion 210 such that the ozone removal filter 230 is provided in the water electrolytic cell 10.

(20) Meanwhile, the level sensor 203 shown in the first and second embodiments of the present invention may be chosen from various sensors, but a float sensor is used in the present invention for a compact size of entire volume of the water electrolytic cell 10.

(21) Meanwhile, the ozone removal filter 230 seated in the filter mounting portion 210 may be selected from the group consisting of a carbon block filter 231, activated carbon particles, and an activated carbon nonwoven fabric in which an active carbon is attached to a nonwoven fabric. Any appropriate ozone removal filter 230 fitted to a shape of the filter mounting portion 210 may be used.

(22) Reference numeral 232 in the drawings denotes a silicon film covering the carbon block filter 231.

(23) Hereinbelow, an operational state of the oxygen generator integrated with the ozone removal filter of the present invention will be described.

(24) The oxygen generator of the present invention supplies mineral water to the water electrolytic cell 10 through the water supply hole 201 while supplying power and applying DC voltage to the positive electrode plate 302 and the negative electrode plate 303. Various organic and inorganic materials such as calcium (Ca), Magnesium (Mg), and silicon (Si), etc. act as electrolytes. Oxygen and small amount of ozone are generated from the positive electrode plate 302 disposed on the diaphragm 301, and hydrogen is generated from the negative electrode plate 303 disposed below the diaphraym 301.

(25) The generated oxygen and ozone pass through water in the container body 100 and are gathered at the upper portion of the water electrolytic cell. When a certain pressure is generated, oxygen and ozone are introduced into the filter mounting portion 210 through the through hole 210a of the detachable upper cover 200 or the integrated upper cover 200. Since the silicon film 232 tightly seals a gap between the filter mounting portion 210 and the ozone removal filter 230, ozone and ozone compounds, in which ozone is combined with various organic and inorganic materials contained in mineral water, such as calcium (Ca), magnesium (Mg), silicon (Si), etc, are filtered through the ozone removal filter 230 as passing through only pores of the carbon block filter 231, the activated carbon particles, or the activated carbon nonwoven fabric in which the active carbon is attached to the nonwoven fabric, one of which constitutes the ozone removal filter 230 disposed inside the filter mounting portion 210. Accordingly, only pure oxygen passes through and is discharged through the oxygen discharge hole.

(26) In addition, hydrogen generated from the negative electrode plate 303 is discharged through the hydrogen discharge hole 304, becomes water by combining with oxygen in the air, and evaporates into the air.

(27) Meanwhile, ozone filtered by the ozone removal filter 230 decomposes to oxygen after 15 minutes to 30 minutes which is a half-life of ozone in water, so there is no secondary contamination or residue which means the filter is environmentally friendly.

(28) At this point, the ozone compounds are also removed neatly during decomposition of ozone.

(29) Although the preferred embodiment of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It is thus well known to those skilled in that art that the present invention is not limited to the embodiment disclosed in the detailed description, and the patent right of the present invention should be defined by the scope and spirit of the invention as disclosed in the accompanying claims.
