DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the portable water purifier of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a suction pump for discharging purified water, which is connected to a long filtration cylinder 3 via a cylindrical connector 2 located at an intermediate position. The filter cylinder 3 is filled with a filter material 4 made of activated carbon or the like, and a strainer member 6 having an intake port 5 is attached to the bottom of the filter cylinder 3. Further, on both end sides of the filter material 4 in the filter cylinder 3, the non-woven fabrics 7, 8a, 8b,
A wire net 9 and the like are arranged. In this case, if a replaceable filter member 6a such as a sponge is stored in the concave end of the strainer member 6, even if the water intake source contains dust, mud, etc. Can be removed before inflow.

The suction pump 1 includes a cylinder body 10 and a hollow piston 1 as shown in FIG.
The purified water, which is composed of 1, a spring 12, etc. and has passed through the filter cylinder 4, flows out from an outlet 14 of a water supply head 13 provided at the head of the hollow piston 11. In order to make this suction action smooth, a floating ball is provided at the top of the hollow piston 11 and at the bottom of the cylinder body 10.
15 and 16 are arranged. Further, the spring 12 is located between the curved concave portion 17 of the hollow piston 11 and the bottom portion of the cylinder body 10, and enables the hollow piston 11 to smoothly move up and down.

Further, the outlet 14 of the water supply head 13
Is provided on a tongue member 18 provided on the water supply head 13, communicates with the through hole 19 of the hollow piston 11, and discharges purified water. In the illustrated case, the tongue-shaped member 18 has its mounting inner end 18a pivotally attached so as to be rotatable about 180 °, whereby the protruding state and the receiving groove 2 are formed.
A storage state in 0 is configured. The tongue-shaped member 18
It is needless to say that a configuration in which the tongue-shaped member 18 is slid in the receiving groove 20 can be applied to the protruding state and the accommodation state in the receiving groove 20.

Further, the cylinder body 10 is provided with a mounting cap 21 which is fixed to the outer peripheral portion of the connector 2 by using, for example, a screw at an open end portion into which the hollow piston 11 is inserted, and a filter cylinder. A small diameter portion 24 is formed at the insertion end portion on the fourth side, and is fixed in the receiving hole 23 of the support inner cylinder 22 of the connector 2 using an O-ring or the like. In the illustrated case, the mounting cap 21 is mounted by a lock member 25, and the support inner cylinder 22 is formed in the axial direction toward the cylinder body 10 side. Further, the hollow piston 11 is configured to be able to be housed in the cylinder body 10 for convenience of carrying when not in use. In short, on the other end side of the hollow piston 11, the protrusion member 26 attached to the bottom portion of the cylinder body 10 is fitted into the through hole 19 and locked. In this case, the protrusion member 2
6 has a central hole 27 formed on the upper side so as to have elasticity, and is smoothly inserted into the through hole 19, and a leg portion 28 should be formed on the lower side. Thus, consideration is given to configuring the moving space of the floating ball 16 and the introduction path of purified water.

In the portable water purifier thus constructed, in normal use, the end of the filter cylinder 3 on the side of the strainer member 6 is put in the water source, and the hollow piston 11 of the suction pump 1 is manually operated. By operating, purified water is obtained from the outlet 14 of the water supply head 13. Therefore, it is especially effective for tap water in foreign countries where water quality is poor. Also,
In an emergency such as a large earthquake, it is possible to use a water intake source such as a river, a pool, a bath, etc. It is effective to keep a set of water sanitizers. This is because if the disinfectant is added to the water source, sterilized water can be obtained, and purified water can be easily obtained from the sterilized water.

[0014]

As described above, according to the present invention, the suction pump 1 and the long filtration cylinder 3 can be easily connected by utilizing the cylindrical connector 2. Manual operation by suction pump 1 is also easy,
Moreover, it has an advantage that the amount of purified water treated is large and the portability is excellent. Also, due to the availability of disinfectants for drinking water,
It has the advantage of being able to deal with emergencies.
