Description

  The present invention relates to a simple water purifier that can be used to obtain drinking water from the remaining water of a bath or water of a river or a pond in an emergency such as an earthquake or in an outdoor camp.

  In recent years, household water purifiers installed in the middle of water faucets and water pipes have become widespread, and their performance has also greatly improved. Some of these water purifiers have a porous hollow fiber or activated carbon filter inside, and can sufficiently obtain drinking water from the remaining water of a bath or water of a river or pond. However, since all of these filters use raw water pressure to filter raw water, they cannot be used when there is no water supply in an emergency such as an earthquake or when there is no water supply such as in an outdoor camp.

  For this reason, pressurizing raw water with a manual air pump and passing or passing a filter medium such as a porous hollow fiber or an adsorbent such as activated carbon adsorbs or filters germs, turbid components and organic substances, and is suitable for beverages. A simple water purifier has been proposed.

  For example, Patent Documents 1 and 2 propose a simple water purifier in which a manual pump is attached to a raw water tank and pressurized raw water is guided to a water purifier through a pipe.

Further, in Patent Document 3, a simple water purification system in which compressed air is stored in a tank by inflating a bicycle, the compressed air is guided to a water storage tank to pressurize raw water, and the pressurized raw water is guided to a water purifier. A vessel has been proposed.

  However, in the conventional simple water purifier, the apparatus is large and inconvenient to carry, and it is difficult to store it in a regular emergency evacuation bag. In addition, the apparatus is complicated and the manufacturing cost is high. For this reason, it was not suitable for widespread use as a disaster emergency.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a simple water purifier that is light and small, can be stored in an emergency evacuation bag, and has a low manufacturing cost. And

  When the water supply stops in the event of an emergency such as an earthquake, the inventors use a water purifier attached to a household water faucet or a water purifier attached to a household faucet. We considered reducing the size and manufacturing costs.

  That is, the simple water purifying instrument of the present invention includes a pipe provided with a faucet, and a container mounting portion and a manual pump for attaching a drinking water container to one end of the pipe across the faucet. The water valve is provided, and a water purifier attachment portion is provided on the other end side of the pipe across the water faucet so that a water purifier can be attached.

  In this simple water purifier, first, a versatile container (for example, a PET bottle) containing raw water such as the remaining hot water of a bath is attached to the container mounting portion, and a versatile water purifier (for example, a water purifier mounting portion) Attach a commercially available water purifier attached to the faucet. Then, with the faucet closed, air is introduced from the air valve by a manual pump such as a bicycle inflator and the inside of the container is pressurized. Next, the raw water pressurized by opening the faucet is passed through a water purifier for purification to obtain drinking water.

  This simple water purifier is not equipped with a container for storing raw water, a manual pump, or a filter for water purification.If necessary, a plastic bottle, a bicycle air purifier, a water purifier for water supply, etc. The raw water can be easily purified simply by procuring it and attaching it to the simple water purification apparatus of the present invention. For this reason, the number of parts is small, the structure is extremely simple, and the manufacturing cost is low. In addition, since the device can be made small enough to be placed on the palm of the hand, it is lightweight and compact, convenient to carry, and can be stored in an emergency evacuation bag.

  The air valve may be a bicycle tire air valve. Bicycle inflaters are easy to procure because they are in most homes, and are simple water purifiers that can be used anywhere in the event of a disaster.

The container mounting portion may be provided with a female screw that is screwed into a male screw of the beverage container. Since a beverage container with a male screw such as a PET bottle can be easily obtained even in the event of a disaster, it becomes a simple water purifier that can be used anywhere using the empty bottle.

  It is preferable that the water purifier for water supplies filters raw water with activated carbon and porous hollow fiber. Activated carbon can effectively adsorb organic substances such as musty odor substances in raw water, and porous hollow fiber can filter bacteria and turbid components in raw water. For this reason, the water especially suitable for drinks can be obtained. In the case of a water purifier that does not use a porous hollow fiber, it is preferable to mix an appropriate amount of a disinfectant such as sodium hypochlorite in raw water. As a result, Escherichia coli and the like in the raw water can be sterilized, and the added bactericide and the generated trihalomethane can be removed with activated carbon, so that sanitary and safe drinking water can be secured.

  Furthermore, it is also preferable that a foldable container that can be attached to the container attaching portion is provided. If it is like this, when using the instrument for simple water purification, it is not necessary to procure the container which puts raw | natural water on the spot. In addition, since a folding container does not take up space for storage, it can be stored in a regular emergency evacuation bag.

The simple water purification apparatus of the present invention is extremely compact because it can use an empty bottle such as a PET bottle or a bicycle air bag. For this reason, it can be stored in a regular emergency evacuation bag, taken out and used in an emergency.
Moreover, you may put the water purifier for water supplies together with the simple water purifier of this invention in the emergency evacuation bag for a maintenance. This is convenient because it is not necessary to search for a water purifier for use at the time of use. Furthermore, the water purifier for water supply can also be previously attached to the simple water purifier of the present invention. Moreover, if a plastic bottle containing drinking water is put in the emergency evacuation bag, the empty bottle after drinking and drinking the drinking water of the plastic bottle can be used for the simple water purifier of the present invention. . Furthermore, a collapsible container that can be attached to the container attachment portion (for example, a bellows-type water-threaded water bottle) may be put together. If it becomes like this, it will become still more compact and it is not necessary to look for the container which puts raw water when using the instrument for simple water purification.

  Although there is no limitation in particular about the kind of faucet of the instrument for simple water purification of this invention, the normal faucet used for the faucet of a water supply can be used. Moreover, if the pipe and faucet provided with the faucet are made of plastic, the weight can be reduced.

As an air valve, if it is an air valve that can accommodate a bicycle, it is convenient because it can be pressurized using a bicycle inflatable that can be procured anywhere. Moreover, you may use the air valve suitable for a bellows type hand pump used for a floating ring. Such hand pumps are extremely compact, lightweight and space-saving, so they can be put together in emergency evacuation bags.
Hereinafter, a specific embodiment to which the present invention is applied will be described with reference to the drawings.
