FIG. 1 is a perspective view showing an embodiment of the water purifier of the present invention. This water purifier includes a capsule cartridge 10 made of synthetic resin or metal, preferably synthetic resin, in which a cartridge 11 containing activated carbon or ceramic is enclosed, and a raw water supply pipe 12 and a purified water discharge pipe 13 are attached to the bottom. It has a housing 20 for fixing the capsule cartridge 10 to supply and purify raw water and discharging purified water, and has a fastening ring 30 for securing the capsule cartridge 10 if necessary.

In the present invention, the raw water supply pipe 12 and the purified water discharge pipe 13 of the capsule cartridge 10 are provided with ball valves 14, 14, respectively (FIG. 2). The ball valve 14 is pressed by a spring 16 pressed by a pressing plate 15 to close the raw water supply pipe 12 and the purified water discharge pipe 13.

The holding plate 15 is formed to have a smaller diameter than the inner diameter of the capsule 17 of the capsule cartridge 10, and the cartridge 11 is placed thereon, and the spring 16 and the ball valve 14 are pressed by the pressure.
A hole 151 having substantially the same diameter as the through-hole 111 is formed in a portion that comes into contact with the through-hole 111 provided at the central portion of the first through-hole 1.

A hole 15 is formed in the lower surface of the holding plate 15.
1, a purified water discharge pipe 13 having the same diameter as the hole 151 or a diameter slightly larger than the hole 151 is attached. The ball valve 14 is stopped by a convex body 131 provided at an appropriate position on the inner surface of the purified water discharge pipe 13, and is pressed by a spring 16 hooked on a portion surrounded by the purified water discharge pipe 13 on the lower surface of the holding plate 15. It is being done. In addition, this purified water discharge pipe 13
Extends through the bottom 171 of the capsule 17 outward at a constant length.

On the other hand, the raw water supply pipe 12 communicates with a hole formed in the bottom 171 of the capsule 17 and is attached to the outer surface of the bottom 171. The ball valve 14 is connected to the raw water discharge pipe 1
The spring 16 is stopped by a convex body 121 provided at an appropriate position on the inner surface of the holding plate 2 and pressed against the lower surface of the holding plate 15.
Pressed by. The length of the externally exposed portion of the raw water supply pipe 12 is the same as that of the externally exposed portion of the purified water discharge pipe 13.

The raw water supply pipe 12 does not enter the inside of the capsule 17, or even if it enters, it has a short length and does not contact the presser plate 15. Therefore, in order to sufficiently secure the position of the spring 16, it is preferable that three or more rod-shaped holding rods 152 hang down from the lower surface of the holding plate 15 to prevent the spring 16 from laterally shifting (FIG. 2). ). The holding rod 152 has a length equal to or less than the length of the purified water discharge pipe 13 in the capsule 17 and is fixed to the holding plate 15 at equal intervals.

As another method of holding the spring 16, the raw water supply pipe 12 is formed to have the same diameter and the same length as the purified water discharge pipe 13, the upper end of which is fixed to the lower surface of the holding plate 15, and enters the inside of the capsule 17. The spring 16 may be secured by providing an appropriate number of water holes 122 in the portion so that raw water can be supplied into the capsule 17 (FIG. 3).

In the present invention, the inner diameter of the capsule 17 is made larger than the outer diameter of the cartridge 11,
When the cartridge 11 is accommodated, raw water can enter the gap between the two.

Further, the upper end 172 of the capsule 17
Is formed in a bowl shape or a conical shape in which the inner diameter gradually narrows, and the upper end of the cylindrical cartridge 11 is pressed against the upper end portion 172 so that raw water does not enter through the upper portion of the through hole 111 of the cartridge 11 ( (Fig. 3).

As an alternative, an annular projection is provided around the inside of the capsule 17 and the cartridge 11
The upper end of each of them may be pressed against each other to prevent intrusion of raw water (not shown).

The housing 20 used in the present invention is an instrument having a function of fixing the capsule cartridge 10, supplying raw water thereto, and receiving purified water purified by the capsule cartridge 10. Therefore, it is made of synthetic resin or metal, but it is preferable to make it with a heavy and stable metal.

The housing 20 includes a conduit 21 for supplying raw water and receiving and sending purified water, fitting cylinders 22 and 22 having a diameter into which the raw water supply pipe 12 and the purified water discharge pipe 13 of the capsule cartridge 10 can be fitted, and a capsule cartridge. And push-up tools 23, 23 for pushing up the ten ball valves 14, 14.

The fitting tube 22 is implanted in the conduit 21 so as to communicate with a hole formed in the conduit 21, and is fixed to a support member 221 protruding from the inner wall of the fitting tube 22.
The push-up tool 23 is supported upright. This push-up tool 2
The size of 3 is set to a length and a diameter sufficient to push up the ball valves 14 and 14 by inserting the push-up tools 23 and 23 into the raw water supply pipe 12 and the purified water discharge pipe 13 of the capsule cartridge 10, respectively. The tip is the conduit 2
It is located at the same height as or slightly lower than the opening surface of No. 1.

The push-up tool 23 is usually formed in a rod shape, and is attached so that the base is fixed to the rod-shaped support phase 221.

In the latter case, since the fitting tube 22 does not communicate with the hole formed in the conduit 21 and water does not pass through the fitting tube 22, the cylindrical push-up tool 23 causes the ball valve 1
When pushing up 4, an appropriate number of water through holes 231 are opened in a portion that penetrates the bottom portion 171 of the capsule 17 and enters the capsule 17 so that water can flow.

Further, the two fitting cylinders 2 of the conduit 21
A partition 211 is provided inside the space between 2 and 22 so that raw water and purified water do not mix.

It is preferable that the housing 20 be provided with a cover 24 for protecting and covering the whole except for the opening of each fitting tube 22 and both ends of the conduit 21 (FIG. 2).

Further, when the cover 24 is used, it is preferable to attach a fastening ring 30 to the capsule 24 to secure the capsule cartridge 10.
The tightening ring 30 is formed as a ring having a vertical cross-section ““ ”and having a structure in which the upper end protrudes toward the inside, and the protruding portion 31 is formed by a flange portion whose lower surface is provided around the bottom portion 171 of the capsule 17. After being hung so as to be in contact with the upper surface of the 173, the inner surface 32 of the fastening ring 30 and the outer surface 241 of the cover 24 are screwed together. With this configuration, it is possible to prevent the capsule cartridge 10 and the housing 20 from being accidentally detached due to vibration during use.

The water purifier of the present invention has the above-mentioned structure, and is used as follows. First, the raw water supply pipe 12 and the purified water discharge pipe 1 of the capsule cartridge 10
3 is pushed into the fitting cylinders 22, 22 of the housing 20.
Then, the push-up tools 23, 23 in the fitting cylinders 22, 22, push up the ball valves 14, 14, respectively, to form water passages. When the fastening ring 30 is used, it is applied here as described above.

After doing so, both ends of the conduit 21 of the housing 20 are connected to the raw water pipe 40 and the purified water pipe 50, and the raw water is supplied from the raw water pipe 40 to the conduit 21. The supplied raw water flows into the capsule 17 through the raw water supply pipe 12 fitted into the fitting tube 22 or the water through hole 231 of the cylindrical push-up tool 23.

The raw water that has flowed in is filled in the space between the capsule 17 and the cartridge 11,
1 and is purified. Purified water is through hole 1
11, flows down and flows down into the hole 151 of the holding plate 15 and the water passage hole 23 of the purified water discharge pipe 13 or the cylindrical push-up tool 23.
It flows down to the conduit 21 through 1 and is sent out to the water purification pipe 50.

When the capsule cartridge 10 is to be removed, it may be simply pulled out from the housing 20.
When the capsule cartridge 10 is pulled out, the push-up tool 23,
Since there is no pressing of the ball valves 14 and 14 by the 23, the ball valves 14 and 14 instantaneously close the raw water supply pipe 12 and the purified water discharge pipe 13, so that the residual water in the capsule cartridge 10 does not spill out.

[0027]

According to the water purifier of the present invention, when the used capsule cartridge is removed, the raw water supply pipe and the purified water discharge pipe of the capsule are instantaneously closed, so that when the capsule cartridge is replaced, residual water spills out and the surrounding area is flooded. There are benefits that can be prevented.
