The present invention relates to a simple water purifier that can be used when river water, lake water, etc. are used as drinking water.

[Prior Art] Various types of simple water purifiers have been commercially available, but most of them are used only by attaching them to household water faucets or are used only as portable devices. Water purifiers that could be used for both business and portable purposes were unknown. A simple water purifier is known that stores activated carbon in a container and allows the water to be treated to contact and pass through the activated carbon layer to remove odor components in the water to be treated, such as chlorine odor in tap water. There is. However, although a simple water purifier containing only activated carbon in a container can adsorb and remove residual chlorine and certain organic substances from tap water, it cannot remove even bacteria from the water. Furthermore, it has been pointed out that when such a water purifier is used for a long period of time, the activated carbon layer becomes a breeding ground for bacteria, which is not sanitary.

[Purpose of the invention] The purpose of the invention is that it can be used for home use by attaching it to a tap water faucet, it can also be used as a portable device, and in addition to removing odor components from water, An object of the present invention is to provide a water purifier having a simple structure and having an advanced purification function capable of removing even bacteria.

[Configuration of the invention] That is, the simple water purifier of the present invention includes a container forming a main body of the water purifier, and a container that can be detachably attached to the container.
a cap equipped with a pneumatic action section having an air venting mechanism, a check valve and a pressurizing mechanism, a treated water inlet having an opening/closing mechanism, and a purified water outlet; connected to the cap, with an activated carbon layer and at least one end in an open state; and a filtration section in which a retained hollow fiber membrane is housed in a chamber.

[Preferred mode for carrying out the invention] The simple water purifier of the invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic cross-sectional view showing one embodiment of the simple water purifier of the present invention.

In the simple water purifier of the present invention, the filtration section that performs the purification function is constructed by housing an activated carbon layer 1 and a hollow fiber filtration membrane 2 in a cylindrical chamber 3. Activated carbon layer 1
As the activated carbon to be filled in, granular activated carbon, powdered activated carbon, etc., and more specifically, granular coconut shell activated carbon, for example, are preferably used. Activated carbon layer 1 is
In order to minimize the movement of the filled particles within the chamber 3 due to water flow, a grid-like support made of wire mesh or the like is attached to the upper and lower ends of the activated carbon layer 1 within the chamber 3, and the inside thereof is filled. is preferred.

As the hollow fiber filtration membrane 2, porous or homogeneous hollow fiber membranes made of, for example, polyacrylonitrile, polyvinyl alcohol, polymethyl methacrylate, polysulfone, cellulose, cellulose acetate, polypropylene, polyethylene, etc. can be used. It is preferable to use a porous hollow fiber membrane made of polyolefin, such as polyethylene or polypropylene, which has excellent bacteria removal ability, large water permeability, and excellent water resistance. It is necessary that the hollow fiber filtration membrane 2 is housed in the container 3 with at least one end thereof keeping the opening of the hollow fiber, and as a means for storing it in this way, for example, the method shown in FIG. After bundling the hollow fiber filtration membranes 2 into a U-shape, or sealing one end of the hollow fiber filtration membranes 2 and bundling them, use a resin adhesive to prevent the open ends of the hollow fibers from being blocked. chamber 3
Just glue and fix it inside.

As the cylindrical chamber 3 that houses the activated carbon layer 1 and the hollow fiber filtration membrane 2, a cylindrical body made of plastic, metal, etc. can be used, but it is usually made of lightweight polyester, polyethylene, polycarbonate, polymethyl methane, etc. A cylindrical plastic container made of acrylate or the like is used.

In the simple water purifier of the present invention, the chamber 3 constituting the filtration section can be connected to the cap 4, and the purified water that has passed through the chamber 3 is guided to the purified water outlet attached to the cap 4 in a sealed state. It is necessary that the configuration is as follows.
The connection state may be such that the chamber 3 is fixed to the cap 4, or may be detachable. Usually, it has a detachable structure, and if the adsorption capacity of the activated carbon layer 1 in the chamber 3 for odor components etc. decreases, or if the porous hollow fiber membrane 2 becomes clogged and the water permeation rate decreases, It is preferable to configure it as a so-called cartridge type in which a spare chamber 3 is used by replacing it.

In the simple water purifier of the present invention, the pneumatic acting section that performs the liquid feeding function is constituted by an air venting mechanism 5, a check valve 6, and a pressurizing mechanism 7. The air pressure inlet is
For example, a tubular member 8 made of metal plastic or the like.
It is manufactured by attaching, for example, a screw-type air vent mechanism 5, a check valve 6 made of rubber, silicone resin, etc., and a pressure mechanism 7 made of, for example, a rubber ball.

The inlet of the water to be treated is connected to a tubular member 9 made of metal, plastic, etc., with an opening/closing mechanism 1 such as a cock.
It is created by attaching 0. Further, the purified water outlet is also made using a tubular member 11 made of metal, plastic, or the like.

The cap 4 is provided with a hole for providing a pneumatic acting part, a hole for providing an inlet for treated water, and a hole for providing an outlet for treated water. The cap 4 for the simple water purifier of the present invention is fabricated by attaching the above-mentioned air pressure acting portion, the inlet for water to be treated, and the outlet for purified water to the cap 4 in these holes. Furthermore, the cap 4 is provided with a thread groove 12, for example, and has a structure that can be screwed into the thread groove 12 of the container 13 forming the main body of the water purifier, so that the cap 4 and the container 13 can be freely attached and detached. It can be done.

Container 13 is suitably made from relatively lightweight metal or plastic.

Each component of the simple water purifier as described above is
The simple water purifier of the present invention is completed by assembling as shown in the figure.

Next, how to use the simple water purifier of the present invention will be briefly explained. When using this simple water purifier as a portable device, do not use the water inlet to be treated.
After removing the cap 4 from the container 13 and filling the container 13 with water to be treated, such as river water, lakes, marshes, etc., attach the cap 4 and close the opening/closing pot 10 at the inlet of the water to be treated. When operated, air is forced into the container 13 by the action of the check valve 6, and the water to be treated is purified by passing through the activated carbon layer 1 in the chamber 3 and the hollow fiber membrane 2, and then flowing out from the purified water outlet. Purified water can be obtained. In this purification process, the activated carbon layer 1 first adsorbs and removes odor components and some organic matter in the water to be treated, and then the hollow fiber membrane 2 prevents fine suspended matter and bacteria from passing through the water. The resulting purified water is highly purified and hygienic and suitable for drinking.

In particular, when river water, lake water, etc. must be used as drinking water in the event of a disaster such as an earthquake or flood, or when river water or lake water is used as drinking water for camping, hiking, etc., the simple method described above is useful. It has high practical value because sterile drinking water can be obtained through operation.

On the other hand, when the simple water purifier of the present invention is used for home use, the tubular member 9 at the inlet of the water to be treated is connected to the tap water faucet with the cap 4 attached to the container 13, and the opening/closing pot 10 and the air vent are connected. The container 13 is filled with tap water by opening the mechanism 5 and opening the tap of the tap water faucet to flow water. In this process, the air inside the container 13 is exhausted through the air venting mechanism 5, and when the air venting mechanism 5 is closed when the inside of the container 13 is nearly full, the water pressure of the tap water causes the tap water to be treated to form the activated carbon layer 1 and Purified tap water is discharged from the purified water outlet through the hollow fiber membrane 2. When purifying tap water, the activated carbon layer 1 removes odor components, such as chlorine odor, from the tap water, resulting in delicious water. In addition, if it is used for a long period of time under such conditions, even if bacteria may grow in the activated carbon layer 1, the hollow fiber membrane 2 will prevent the bacteria from passing through, resulting in sanitary conditions. You can get delicious purified water.

[Effects of the present invention] The simple water purifier of the present invention can be used for home and portable use to obtain highly purified, hygienic, and delicious water. Its practical value is extremely high, as it can be used to secure hygienic drinking water in an emergency by carrying it with you at the time of travel or while camping or at the register.
