Description

  The present invention relates to a small water purifier that can remove contaminants from water contaminated with bacteria or the like to make ultra-soft water suitable for beverages and is portable.

  There are many people who travel abroad from Japan, but it is the problem of drinking water that Japanese people are most troubled with for long-term overseas trips. If you drink fresh water as it is in a foreign country, there is a risk of diarrhea. Even if you boil foreign water and drink it as coffee or tea, it is not delicious.

  Furthermore, for example, if you travel to China and wash your face with hot water or wash your hair, your skin will be rough and your hair will become dry.

  It would be convenient to have a water purifier that can remove bacteria, viruses, etc. that can be carried on a trip abroad, but such a water purifier has not been known. This is because such a water purifier requires an RO membrane, but it is a water purifier that uses the RO membrane to make it suitable for drinking, and could not be miniaturized to be portable.

An object of the present invention is to provide a portable water purifier capable of removing contaminants from water contaminated with bacteria, etc., making it ultra soft water, and making it a very delicious beverage when drinking as coffee or tea. And

In order to achieve the above object, the present inventor, as a result of earnest research, purified water that has passed through a sterilization filter such as RO membrane, by passing through a cation exchange resin, it becomes complete soft water (super soft water), When this soft water is further passed through bioceramics, it has been found that when drinking as coffee or tea, it becomes very delicious water, and the present invention has been achieved.

That is, the present invention is a pre-filtration device for water to be treated, a sterilization filter for sterilizing water filtered by the pre-filtration device, a cation exchange resin for softening the purified water filtered by the sterilization filter, And bioceramics that allow soft water that has passed through the cation exchange resin to pass therethrough.

The sterilization filter is preferably a reverse osmosis membrane filtration device because it can remove not only pathogenic bacteria but also viruses (Claim 3). It is preferable that the concentrated water of the reverse osmosis membrane filtration device is filtered by the second reverse osmosis membrane filtration device because the amount of water treated can be increased (claim 4).
When filtering river water or the like, the prefiltration device and the sterilization filter are pressurized with a pump to filter the water to be treated (Claim 5).

As described above, according to the present invention, it can be easily carried on a foreign trip or the like, and if this water purifier is used, it is possible to drink fresh water as it is in a foreign country. Moreover, not only can it be sterilized, but it can also be very tasty when taken as coffee. Furthermore, washing your hair with this water or washing your hair will make your skin and hair smoother, so it will be greatly appreciated by women.

  It is considered that the use of water made by passing ultra-soft water through bioceramics makes coffee etc. delicious because this water enhances the function of the human body.

  The reason why the device of the present invention can be made small and portable is that the use of bioceramics eliminates the need for stone as mineral water.

Next, an embodiment of the present invention will be described.

FIG. 1 is a flowchart showing an embodiment of the present invention.
If the water pressure of tap water is greater than 3.5 kg, the pump is unnecessary. Without a pump, tap water can pass through the RO membrane.

  Use a pump when the tap water pressure is 3.5 kg or less or when river water is used. In this embodiment, a pump that produces a pressure of 10 kg at 12 VDC is used. The power source of the pump can be used from AC 100 V 50 hz / 60 hz, AC 200 V 50 hz, or a car battery, but for travel, it is preferably set to AC 200 V because it is mainly used in foreign countries. In this embodiment, AC200V is set to DC12V by a known method.

  As shown in FIG. 2 (C), the pump is driven to suck water from the hose 2 into the bucket (treated water container) 1. A suction cup (not shown) whose center is opened is fixed to the tip of the hose 2, and this suction cup is fixed to the bucket 1 by suction. In this way, the hose 2 is prevented from being detached from the bucket 1.

  As shown in FIG. 1, the water sucked from the bucket 2 is filtered through a filter (pre-filter device) 3 filled with activated carbon that removes coarse dust to remove insoluble matters.

The water filtered by the prefiltration device 3 is filtered by the first-stage reverse osmosis membrane filtration device (RO membrane) 5. The reverse osmosis membrane filtration device 5 removes all impurities such as bacteria. In addition, the prefiltration apparatus 3 and the reverse osmosis membrane filtration apparatuses 5 and 7 pressurize and filter with the pump 4.

The water filtered by the first-stage reverse osmosis membrane filtration device 5 is sent to a water softening vessel 6 filled with a cation exchange resin.
The concentrated water that has not passed through the first-stage reverse osmosis membrane filtration device 5 is filtered by the second-stage reverse osmosis membrane filtration device (RO membrane) 7 and filtered by the first-stage reverse osmosis membrane filtration device 5. It is sent to the water softening container 6 together with the purified water.

  The water softening vessel 6 is filled with a cation exchange resin. By passing the purified water through the water softening vessel 6 filled with the cation exchange resin, the water is changed from hard water to completely super soft water.

  The soft water that has passed through the water softening vessel 6 is sent to a vessel 8 filled with bioceramics. The water that has passed through the bioceramics 8 becomes drinking water that can be drunk as raw water, and is taken out from the drinking water outlet 11.

  The pure water that has passed through the reverse osmosis membrane filtration devices 5 and 7 does not contain impurities, so it is said to be bad for the human body.

  However, a mineral extraction container using pure water as mineral water may be provided between the reverse osmosis membrane filtration devices (RO membranes) 5 and 7 and the water softening container 6. However, it is not preferable for travel purposes because of its large size. Further, it is preferable not to use mineral water because it enhances the original taste of coffee or the like.

  The concentrated water that has not passed through the second-stage reverse osmosis membrane filtration device 7 is discharged from a drain nozzle (drain) 9.

  In the above embodiment, the reverse osmosis membrane filtration device is connected in two stages, but it may be in one stage. However, by using two stages as described above, the amount of water treated can be increased. In this embodiment, since the reverse osmosis membrane filtration devices are connected in two stages, 30 liters of drinking water can be obtained per hour.

  In the above example, a reverse osmosis membrane filtration device was used as a sterilization filter. However, since tap water does not contain viruses (killed by chlorine), other sterilization filters can be used when using tap water. There is no problem. However, since well water or river water contains viruses, it is preferable to use a reverse osmosis membrane filtration device for safety. Furthermore, since the water passed through the reverse osmosis membrane filtration device further enhances the taste of coffee or the like, it is preferable to use the reverse osmosis membrane filtration device also in this respect.

As is apparent from FIG. 2, the device of the present invention of this embodiment has a height of 30 cm, a width of 23 cm, and a depth of 38 cm. Therefore, since it is very small, it can be easily accommodated in the travel bag 10 as shown in FIG.
The water purifier of the present invention is mainly used for overseas travel, but can also be suitably used for camping and home use.

The water purifier of the present invention is small and portable, and not only can drink fresh water as it is in foreign countries, but if you use this water, coffee and tea will become very delicious, and if you wash your face and hair with this water, Since hair becomes smooth, it is expected to spread in large quantities to overseas travelers.
