JP2002355670A - Device for pressurizing portable water cleaner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a device for pressurizing a portable water cleaner which is inexpensive, light, and compact, and excellent in portability. SOLUTION: In this device for pressurizing a portable water cleaner, an existing airtight plastic bag with a zip fastener and an existing portable filter are used, which makes the price of a product remarkably low. An existing sponge or the like is used as a flexible material that is used as the pressure device in a stand-alone state, which enables the product to be used as a low-cost and simple air pump.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple water purifying filter for easily obtaining drinking water in disasters, mountain climbing, trekking, outdoors and the like.

[0002]

2. Description of the Related Art Conventionally, a portable water purifier has been required to purify raw water by applying pressure to the raw water and passing through a filter. For example, a publication number: Japanese Patent Laid-Open No. 7-237828
31398 JP-A-10-137740
85 As a pump for pressurizing raw water, there were a bellows type, a piston type and the like.

[0003]

The conventional portable water purifier requires a dedicated container for containing raw water, and the container is bulky, so that it is not suitable for storage in a backpack or the like during mountain climbing. Special containers were required and the production cost was high, making it difficult to spread.

[0004] The present invention is a pressurizing device for a portable simple water purifier invented for the purpose of low cost, low size, and low weight.

[0005]

In order to achieve the above object,
In the present invention, a commercially available plastic bag with a zipper (3) is used as a container for storing raw water, an existing cassette-type filter material (5) is used as a water purifier, a water purifier inlet is configured as a cap (2), and raw water is supplied at the center of the cap. Provide holes for injection. A plastic bag (3) is in contact with the water inlet of the water purifier, and a cap (2) is attached from the inside of the plastic bag to insert the vinyl into the water purifier. Drill a hole in the vinyl between the water purifier and the cap.

[0006] The shape of the water purifier described above is cylindrical or
The shape of the cap should be circular or square, and a hole for water injection should be provided in the center of the cap.

[0007] The above-described container for storing raw water uses an existing highly airtight plastic bag with a chuck. Instead of the chuck, the mouth of the plastic bag for storing raw water is sealed with an airtight metal fitting or the like. Is also good.

[0008] The cap structure described above may be a structure that covers the water purifier inlet.

[0009] The cap structure described above may be configured to be pushed into the water purifier inlet.

[0010] The cap structure described above may be screwed into the water purifier inlet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments. 1 and 2 are perspective views of an embodiment of a pressurizing device for a portable water purifier of the present invention. FIG. 3 are perspective views of an embodiment of the present invention in which a pressurizing device is a simple air pump.

The chuck (4) of the highly airtight plastic bag (3) is opened, and the plastic bag is brought into contact with the inlet (6) of the water purifier (1), and a hole is provided at the center from the inside of the plastic bag to the inlet. Attach the cap (2) and make a hole in the plastic bag,
1 and 2, wherein raw water is sealed with an inlet chuck (4).

The cap (2) is opened by opening the chuck (4) of the highly airtight plastic bag (3), contacting the plastic bag with the case (8) with a discharge valve, and providing a hole in the center from the inside of the plastic bag to the discharge case. Attach and make a hole in the plastic bag. A cap (2) with a hole in the center is attached to the case (9) with a suction valve from the inside of the plastic bag, and a hole is made in the plastic bag. Put the material that can be compressed and restored into a plastic bag (3)
For example, a perspective view of the embodiment shown in FIG.

[0014]

The present invention is constructed as described above, so that it can be made lightweight, compact and inexpensive. When the portable water purifier of the present invention is used, it is easy to store and carry, and it is easy to secure drinking water outdoors in mountain climbing, camping, trekking and the like. In addition, when tap water cannot be used due to an earthquake or the like, drinking water can be easily secured by using the portable water purifier of the present invention.

[0015]

[Application example of the effect of the present invention] An air valve is attached to a highly airtight plastic bag, a material that can be compressed and restored is put in, a sponge is put in, for example, and the bag is chucked. Can be applied.
