Description

Detailed Description of the Invention "Industrial Application Field" The present invention allows water, floating water, and other raw water to pass through a filtration tank in a container, and eliminates impurities, chlorine, chlorine odor, and harmful odors contained in the raw water. The present invention relates to a water purifier that removes harmful bacteria, filters, sterilizes water, and adds minerals to produce drinking water that is useful for health.

"Prior Art and its Problems" It has been well known that tap water, well water, and other raw water contain impurities that are harmful from a sanitary and cosmetic standpoint.

Water purification methods for removing such harmful substances include rapid forced filtration and slow sedimentation filtration.

The rapid forced filtration method is a method that forcibly brings about a large and rapid filtration effect by applying additional pressure to the water, but this method is expensive when purifying a small volume of water, and it also reduces the water consumption. There is a problem in that it is not possible to take out the material in a timely manner.

On the other hand, the slow sedimentation filtration method is a method in which water is stored in a filter and the water is filtered in a natural flow state due to the water's gravity.While the water purification effect is good, the water flow is slow. It has the disadvantage of

Some conventional water purifiers that employ slow sedimentation filtration methods use ion exchange resins, but ion exchange resins only have a filtration effect and are unlikely to have any other effects. The flow becomes even slower.

In addition, some conventional water purifiers involve soaking mineral-containing medicinal stones or mixing in medicinal solutions, but while these methods are effective for producing mineral water, they do not require filtration or sterilization of the water. The water purification effect is insufficient.

Furthermore, to supplement this, diatomaceous earth or diatomite powder is placed in the filter and crushed by water pressure so that it adheres uniformly to the filter net, and the raw water passes between the diatomaceous earth or diatomite and the filter net. A structure designed to do so has been developed, but it has not been put to practical use because it is impossible to uniformly crush the diatom or diatomaceous powder contained therein.

Furthermore, since the filter and container are integrally formed in all water saving devices, even if they are formed separately, they cannot be easily removed at home, so they can only be used for a certain period of time. The problem was that there was no.

In view of the drawbacks of the prior art, the technical problem of the present invention is to
The filter is designed to be removable and the purified water once filtered is discharged to the outside without backflowing, and impurities contained in the raw water can be easily removed, and it also has sterilization and mineral generation functions. Our goal is to provide a water purifier that can

"Means for Solving the Problems" In order to achieve such technical problems, the present invention aims to solve the problems by forming a silica layer,
An activated carbon layer and a coral grain layer coated with silver nitrate were layered one after another while being pressed with appropriate pressure, and a raw water reservoir was formed on top of the diseased body through a push plate with one through hole. It consists of a filter and a cylindrical container for storing purified water that has passed through the filter main body from a raw water storage part, the peripheral surface of the raw water storage part is formed to have the same diameter as the inner peripheral surface of the cylindrical container, and the filter is A water purifier is proposed which is fitted in a predetermined position within a container, and in which a part of the circumferential surface is recessed to form a drainage channel that communicates between the purified water reservoir portion of the container and the drain port.

"action" According to such technical means, silica layer, activated carbon layer.

The filtration body was formed by sequentially laminating layers of coral grains coated with silver nitrate and pressing them with a predetermined pressure. While the particles of silica stone are in close contact with each other as they flow, some of the impurities are attached to the surface of the silica stone and filtered, and the impurities are completely adsorbed and removed through the activated carbon in the middle, while at the same time softening the water. Obtains deodorizing effect,
In the process of passing through coral sand or crushed coral, which is made up of small particles at the bottom, it comes into contact with the silver nitrate coated on the surface and is sterilized.It also contains minerals eluted from the coral sand, and purified water that has mineral effects flows out. .

In this case, bacteria adsorbed on the activated carbon in the middle part may propagate and flow to the lower side. Even in such cases,
Since the coral grain layer coated with silver nitrate is placed at the bottom, the silver nitrate can sterilize the bacteria that leaked out.

The purified water is placed in a purified water reservoir below the container, and is discharged from the outlet while tilting the container. The filter is fitted in a predetermined position in the container, and a part of the circumferential surface is recessed to form a drainage flow path that communicates between the purified water reservoir portion of the container and the drain port. Because of this structure, the purified water can be discharged without flowing back into the filter or overflowing to the outside.

Further, since the filter is fitted onto the inner peripheral surface of the container and the container is formed in a cylindrical shape, it can be easily removed from above and replaced. Furthermore, since the raw water reservoir is formed on the upper side of the filtration body, and the surface of the raw water reservoir is tightly fitted to the inner circumference of the container, a considerable amount of water can be stored inside the raw water reservoir at once. The uf function is to put the raw water in, and even if the raw water overflows from the raw water storage part, it will not be bypassed and enter the container.

``Example'' A preferred embodiment of the present invention will be described in detail below by way of example with reference to one drawing. However, unless otherwise specified, the dimensions, materials, shapes, and relative arrangements of the components described in this example are not intended to limit the scope of this invention, but are merely illustrative examples. It's nothing more than that.

After the layers are laminated and filled, the particles are pressed with an appropriate pressure to make each particle adhere, and then a press plate 14 with a large number of black through holes 14a is screwed onto the plate with screws 1B. .

Raw water reservoir 1′! ! The portion 5 has a cylindrical shape that is tightly fitted into the inner peripheral surface of the container 3, and has a ring-shaped annular tip 7 formed at its upper end so that it can be locked to the upper peripheral surface of the container 3. A drain groove 5a is provided to communicate between the water tank 1 and the three purified water reservoirs in the lower example of the container 3, and the drain groove 5a and the outlet l are arranged so as to coincide with each other.

Note that 17 is the raw water before filtration, and 18 is the raw water storage part 5.
This is purified water in which the raw water introduced into the container passes through the filter main body and is stored in the purified water storage part 3a inside the container 3.

In the embodiment of the present invention constructed in this way, the filter body 4 of the filter 8 includes a filter net 8 and coral sand 11 or gravel coated with silver nitrate 1O, or activated carbon 1.
2. After sequentially filling the silica stones 13, by pressing with an appropriate pressure to bring each particle into close contact with each other, and screwing on the pressing plate 14,
Raw water reservoir for filter B! When water is injected into the iS section 5, some of the impurities are adsorbed by the particles and removed while the water flows through the through holes 14a of the push plate 14 through the particles of the 13 layers of silica stone, and then the impurities are removed by the particles of the 12 layers of activated carbon. The impurities are completely adsorbed, the water is softened and deodorized, and the silver nitrate is coated on the surface after passing through the coral layer or gravel layer.
It is sterilized by 0 and becomes mineral purified water containing minerals eluted from internal coral sand 11 or gravel stones,
The water falls through the filter net 8 and the drain hole 8, and the water flows into the container 3.
It will be accommodated in the inner purified water storage section 3a.

The purified water thus filtered is used as drinking water and beauty water which is harmless to the human body, and when drinking, by tilting the container 3, the water is discharged from the outlet 1 through the drainage groove 5a.

After using the water purifier for a certain period of time, remove the filter body 4 from above or remove the push plate 14 and remove the filter body 4 from above.
By replacing the contents, it can be reused repeatedly. Furthermore, the filter 6 can be reused by replacing the cassette.

In addition, when in use, the outlet 1 of the container 3 and the ice drainage groove 5 of the filter 6
Insert the filter 6 into the container 3 so that a matches each other,
On the other hand, when the filter 6 is not in use, the filter 6 is rotated so that the discharge port I and the drainage groove 58 do not coincide with each other, thereby preventing dust from entering from the discharge port.

Furthermore, if the container 3 and the filter 8 are made of transparent plastic material, the contents can be clearly seen, which is even more effective.

"Effects of the Invention" As described above, the present invention has the functions of removing impurities contained in raw water, sterilizing, softening, deodorizing, and producing minerals,
In addition, the filter 6 is configured to be easily replaceable or removable, and the purified water once filtered is discharged to the outside without backflowing, and the raw water before purification is bypassed without passing through the filter.
