Abstract

PROBLEM TO BE SOLVED: To form to be compact and lightweight by fitting a cylindrical manual suction pump to a water purifying means and making the pump communicate with the water purifying means by a water supply pipe. SOLUTION: A cylindrical manual suction pump 4 is fitted to a cylindrical water purifying means 3 comprising an active carbon cartridge 1 and a filter cartridge 2 which are arranged to overlap each other and have approximately equal diameters. In the pump 4, a raw water intake hose 18 is made to communicate with the lower part intake of a manual pump part 17, and the upper part outlet of the pump part 17 is made to communicate with the peripheral space 8 of the housing 5 of the cartridge 1, and the housing 5 of the cartridge 1, the housing 12 of the cartridge 2, and the housing of the pump part 17 are connected with a metal water supply pipe 19. In this way, forming to be compact, lightweight, and portable is made possible.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable water purifier, and more particularly to a portable water purifier equipped with a manual water suction pump.

[0002]

2. Description of the Related Art Various devices using activated carbon or the like for purifying water collected from outdoor pools, ponds, rivers and the like to obtain drinking water are known.

[0003]

However, all of the conventional portable water purifiers have the disadvantage that they take up space, are large, heavy, and inconvenient to carry.

[0004]

SUMMARY OF THE INVENTION A portable water purifier of the present invention comprises a water purifying means comprising a cylindrical activated carbon cartridge and a filter cartridge having substantially the same diameter and mounted vertically on each other, and a water purifying means in parallel with the water purifying means. A tubular manual suction pump means provided for communicating with the water purification means and the manual suction pump means;
And water supply pipe means for connection.

[0005]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the portable water purifier of the present invention has a cylindrical water purifying means 3 comprising a cylindrical activated carbon cartridge 1 having substantially the same diameter and a filter cartridge 2 which are placed one above the other. And a known manual water suction pump means 4 arranged in parallel with the water purification means 3.

Activated carbon cartridge 1 of the water purification means 3
Is an elongated cylindrical outer casing 5, a lower end cap 6 for closing the lower end opening of the cylindrical outer casing 5, and an upper wall 7 for closing the upper end opening.
And an activated carbon cartridge tubular body 9 composed of an outer cylinder and an inner cylinder filled with activated carbon inside the outer casing 5 arranged so as to form a space 8 on the outer periphery thereof; , And a water outlet 11 formed at an intermediate portion of the inner cylinder.

[0008] The filter cartridge 2 is
A cylindrical outer casing 12 whose bottom wall is shared with the upper wall 7 of the outer casing 5; an upper end cap 13 for closing an upper end opening of the outer casing 12; and drinking water having the upper end cap 13 opened. An outlet pipe 14 and a cylindrical filter cartridge in which a filter cloth is pleated and is pleated and arranged in a cylindrical shape so as to have a center hole, which is disposed in the outer casing 12 so as to form a space 15 on its outer periphery. The main body 16 is used.

The activated carbon cartridge tubular body 9
The upper end of the inner cylinder communicates with the inside of the outer casing 12 of the filter cartridge 2 through a hole formed in the upper wall 7.

The water suction pump means 4 includes a manual pump portion 17, a raw water intake hose 18 communicating with a lower water intake port of the manual pump portion 17, an upper water outlet of the pump portion 17 and an outer casing of the activated carbon cartridge 1. 5 outer peripheral space 8
A metal water supply pipe means 19 for communicating between the outer casings 5 and 12 and the outer casing of the manual pump section 17 and a handle 20 connected to the manual pump section 17 are provided. .

Since the portable water purification apparatus of the present invention has the above-described structure, if the manual pump portion 17 is operated by the up and down operation of the handle 20, raw water is removed from the lower portion of the manual pump portion 17 through the hose 18. The raw water is introduced from the mouth into the outer casing 5 of the activated carbon cartridge 1 through the upper water outlet and the water supply pipe means 19, and the raw water enters the activated carbon cartridge tubular main body 9 through the raw water inlets 10 and 10, and is filtered by the activated carbon. Turbidity, smell, color, etc. in raw water are removed.

The filtered water further enters the outer casing 12 of the filter cartridge 2 through the water outlet 11 and the hole in the upper wall 7 and is introduced into the filter cartridge body 17, where filtration and sterilization of fine particles and bacteria are performed. After that, purified water comes out of the outlet pipe 14 through the central cylindrical passage.

[0013]

As described above, according to the portable water purification apparatus of the present invention, the tubular filter cartridge 2 is placed on the tubular activated carbon cartridge 1 and the upper part of the water passage of the activated carbon cartridge 1 is placed in the filter cartridge. 2 and a cylindrical suction pump means 4 along these.
Are arranged side by side, and the two are connected and communicated with each other by a water supply pipe means 19, so that the apparatus can be formed very compact and lightweight, and there is a great advantage that it is extremely convenient to carry.
