BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable water purifier containing a hollow fiber membrane and activated carbon.

[0002]

2. Description of the Related Art In recent years, the demand for water purifiers having a hollow fiber membrane and activated carbon as a basic structure has been rapidly expanding to satisfy consumers' demand for quality improvement of drinking water. Most of these water purifiers are stationary water purifiers, which are used by connecting a changeover valve to a water tap and connected to the water purifier with a hose, and water taps directly connected to the water faucet. There is a situation where a portable water purifier is used in the department.

[0003]

[Problems to be Solved by the Invention] A portable water purifier has a water tap and a filter connected with a rubber fitting and a hose to filter by water pressure, or a container is filled with raw water and the water pressure or simple pressure is applied. There is a method of filtering by applying pressure by a pump.

[0004] However, these water purifiers have the following disadvantages. That is, in the former method, since filtration is performed using tap water pressure, it cannot be used in a place without tap water, and the place of use is limited. On the other hand, in the latter method, the filtration takes too much time with the water pressure of the raw water filled in the container, and the filtration also takes too much time because the pressure does not rise even with a simple pump, so that the life of the water purifier is also short.

An object of the present invention is to improve the drawbacks of the conventional portable water purifier, and to provide a sanitary portable water purifier that can easily obtain purified water at any place. And

[0006]

That is, the present invention provides a main body container having an air inlet and a raw water supply port, and an inner cylinder connected to the raw water supply port and having a check valve at the bottom raw water inlet. A hollow fiber membrane bundle and an activated carbon whose ends are fixed with a potting agent while maintaining an open state therein, and a raw water intake port provided with a raw water filter is provided at a lower portion thereof; An O-ring for maintaining liquid tightness with the inner surface of the cylinder is installed, and a water purification unit cylinder having a water purification nozzle and a handle is provided at the upper part. By reciprocating the water purification unit cylinder in the inner cylinder, The water purifier is configured such that raw water in the main body container is discharged from a water purification water discharge nozzle through a check valve, a raw water filter, an activated carbon layer, and a hollow fiber membrane in order.

[0007]

Hereinafter, the portable water purifier of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a schematic sectional view of an embodiment of the portable water purifier of the present invention. An inner cylinder 4 having a female screw screwed with a male screw of the raw water supply port 2 is connected to a main body container 3 having an air inlet 1 and a raw water supply port 2 for supplying raw water.
The raw water inlet 5 is disposed at the bottom of the inner cylinder 4, and has a check valve 6 that works so that water in the main body container 3 flows only in the direction of the inner cylinder 4. Inside the water purification unit tube 7, a bundle of hollow fiber membranes 8 is fixed with a potting agent 9 while keeping its ends open, and is filled with activated carbon 10. At the lower end of the outer surface of the water purification unit tube 7,
O-rings 11 and 11 ′ are mounted to make the outer surface of the water purification unit tube 7 and the inner surface of the inner tube 4 liquid-tight.
A water purification nozzle 12 communicating with the opening end face of the hollow fiber and a handle 13 are provided on the upper part of the water purification unit tube 7 for the convenience of grasping and raising and lowering the water purification unit tube 7 . The water purification unit tube 7 is mounted in the inner tube 4.
The raw water intake 14 of the water purification unit tube 7 has activated carbon 10
Mesh, non-woven fabric,
A raw water filter 15 made of a sintered body, ceramic, or the like is provided.

When using the water purifier of the present invention, the inner cylinder 4 is detached from the main body container 3, and after the raw water is filled, the inner cylinder 4 is again used.
4 is assembled. Next, when the handle 13 of the water purification unit tube 7 attached to the inner tube 4 is pulled up, the pressure in the inner tube 4 drops below the inside of the main body container 3, and the raw water in the main body container 3 passes through the check valve 6 and is It flows into the cylinder 4. Further, air flows into the main body container 3 from the air introduction port 1 and the atmospheric pressure is maintained. Next, when the handle 13 of the water purification unit cylinder 7 is pushed down, the pressure of the raw water flowing into the inner cylinder 4 by the action of the check valve 6 rises, flows into the water purification unit cylinder 7 through the raw water filter 15 , and the activated carbon 10, The water is filtered while passing through the hollow fiber membrane 8 and the purified water is discharged from the purified water discharge nozzle 12. By repeating the reciprocating movement of the water purification unit cylinder 7, purified water can be obtained.

When the water purifying ability is reduced by using the portable water purifier to a certain extent, if only the water purifying unit tube 7 is replaced, highly purified water can be always obtained, which is very sanitary.

The hollow fiber membrane used in the present invention is not particularly limited, and porous hollow fiber membranes formed from various materials such as polyolefin, cellulose, polysulfone, polyvinyl alcohol, and polyacrylonitrile can be used. Homogeneous hollow fiber membranes are mentioned. Further, as the activated carbon, not only granular activated carbon but also activated carbon fiber or a mixture of activated carbon and an ion exchange resin can be used.

It is also preferable to provide a polyolefin sintered filter layer between the raw water filter and the activated carbon layer for the purpose of removing organic substances.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A main container 3 is made of polyethylene having an inner volume of 1 liter, and
BS resin, dimensions: outer diameter 35 mm, inner diameter 28 mm, length of activated carbon layer part 50 mm, hollow fiber membrane 8 part 50
mm. The activated carbon layer 10 is 30 cc of Kuraray Chemical Co., Ltd. activated carbon T-SB 48/100 mesh, and the hollow fiber membrane 8 is a hollow fiber membrane EHF-270T made of polyethylene ray manufactured by Mitsubishi Rayon Co., Ltd. The membrane area was 0.11 m ^2, and Coronate 4403 and Nipporan 4225 manufactured by Nippon Polyurethane Industry Co., Ltd. were used as the potting agent 9. In addition, the raw water filter 15 includes:
A nylon mesh was used.

In this water purifier, tap water is placed as raw water in the main body container 3 and the handle 13 of the water purification unit tube 7 is reciprocated up and down twice by about 80 mm. As a result, about 150 cc of purified water is discharged from the purified water discharge nozzle 12. I got it. At this time, the force for moving the handle 13 up and down was 2 kg or less.

[0015]

[Effect of the Invention] The portable water purifier of the present invention can easily and quickly obtain purified water by a simple operation of raising and lowering a handle even in a place where there is no tap water. In addition, if only the water purification unit tube is replaced, a high level of purified water can be obtained at all times, and it has many advantages such as being extremely sanitary.
