BEST MODE FOR CARRYING OUT THE INVENTION Next, a portable simple water purifier of the present invention will be described in more detail with reference to a preferred embodiment shown in the drawings. FIG. 1 is a vertical sectional view showing a portable simple water purifier 1 according to an embodiment of the present invention, and FIG. 2 is an overall front view showing the portable simple water purifier 1 according to an embodiment of the present invention.

The portable water purifier 1 of the present invention comprises a water purifier 2 having a water purifying function and a raw water container 3 having a pump function, and they are connected to each other to be used as the simple water purifier 1. The water purifier 2 is formed into a cylindrical shape as a whole, and is composed of a primary water purifier 5 including an activated carbon block 4 and a secondary water purifier 7 including a plurality of hollow fiber membranes 6.

The primary water purification section 5 is composed of an activated carbon block 4. This activated carbon is a carbon material having a large number of fine pores and a large surface area.
Pollutants in lake water, pool water, bath water, and other raw water are adsorbed and removed by the fine pores and surface area.

The secondary water purification section 7 is composed of a large number of hollow fiber membranes 6. The hollow fiber membranes 6 are made of very thin hollow synthetic resin fibers. The fibers are bundled and both ends thereof are fixed with a special resin 8 such as an epoxy resin. The solid fine particles dispersed in the raw water are filtered and purified by the large number of hollow fiber membranes 6.

In the water purifier 2, the numeral 9 designates a primary water purifier 5 for detachably connecting the mouth 10 of the raw water container 3.
It is a mounting port provided in. In the illustrated embodiment,
The female screw-shaped mounting opening 9 and the male screw-shaped opening 10 are screwed freely, but the invention is not limited to this. For example, one can be a recess and the other can be a protrusion. Other attachment means can be used. Reference numeral 11 is an outlet for purified water.

Since the raw water container 3 is formed of a flexible material such as polyethylene resin into a bag shape, the raw water container 3 in which raw water such as river water is stored is firmly grasped by the hand, and the raw water is gripped by the hand. The container 3 is pressurized and the water purification device 2 is operated in the same manner as the pump.
Raw water can be sent to. Reference numeral 12 in the drawing denotes a string attached to the raw water container 3.

Next, the process of producing purified water from raw water such as river water using the portable simple water purifier 1 of the present invention will be described. First, raw water such as river water is taken in through the mouth 10 of the raw water container 3, and for example, about 4 to 5 drops of a sterilant composed of a 3% aqueous solution of scaly for food addition is injected and shaken well to sterilize the raw water.

Then, the mouth portion 10 of the raw water container 3 is attached to and connected to the attachment port 9 of the water purifier 2, and a cup or the like (not shown) is prepared at the purified water outlet 11 to prepare the raw water container. 3 is turned upside up, and the raw water container 3 is pressed by the grip force of the hand, and the raw water is fed into the purification device 2 using the function of the pump. When the treated water starts to drip from the outlet 11, the string 12 attached to the raw water container 3 is hung on an appropriate hook or the like, and then the treated water will naturally drip due to gravity.

Next, the raw water fed into the purifying device 2 is first introduced into a primary water purification section 5, which is composed of an activated carbon block 4 which contains a large number of fine particles. Since it is a carbon material having pores and a large surface area, contaminants in raw water are adsorbed and removed by the fine pores and surface area.

Most of the pollutants in the raw water are adsorbed and removed by the activated carbon block 4 of the primary water purification section 5 and purified as clean drinking water, but in order to obtain a higher degree of safety, it is purified. The raw water is sent to the secondary water purification section 7. The secondary water purification unit 7 is composed of a large number of hollow fiber membranes 6, and the hollow fiber membranes 6 are made of very thin hollow nylon fibers. The dispersed solid particles are filtered and purified.

When the purification work of raw water such as river water is completed, the raw water storage body 3 can be removed from the purification device 2 and stored individually, so that it can be easily carried without taking up space. . Moreover, the portable water purifier 1 of this invention
Because of its light weight, it can be carried conveniently for hiking, mountain climbing, traveling, etc.

[0021]

As described above, according to the portable simple water purifier of the present invention, a desired amount of safe purified water can be easily obtained during disasters such as mountain climbing, hiking, walking and traveling. Further, the water purifier and the raw water container can be attached and detached freely, and since they are lightweight, they are convenient to carry.

Further, according to the portable water purifier of the present invention, since the water purifying device is composed of the primary water purifying section consisting of the activated carbon block and the secondary water purifying section consisting of a large number of hollow fiber membranes, it is highly safe. Drinking water having properties can be easily obtained.

Further, since the raw water container of the present invention is formed into a bag shape with a flexible material such as polyethylene resin, the raw water container containing the raw water such as river water is strongly grasped by the hand, It is possible to pressurize the raw water container with a grip force and feed the raw water to the water purifier like a pump, so that a large amount of purified water can be easily obtained.
