Since a low pressure is maintained in the first hole part 110 , the internal filling material disposed inside the cartridge 100 is discharged.

Here, since the pressure is lowered according to the speed of the flow of the water to be treated, the pressure inside the cartridge 100 is also lowered, so that a part of the water to be treated is introduced through the second hole 210 configured in the cartridge 100. The inner filler is diluted with the inner filler, and the diluted inner filler is configured to continuously flow out, so that the amount of the inner filler flows out is adjusted according to the flow rate of the water to be treated.

The perforated plate part 260 is configured to constitute a space part in the upper part of the second hole part 210 configured in the cap part 200 of the second embodiment. Due to this configuration, the water film phenomenon can be prevented.

The perforated plate part 260 includes a plurality of legs radially from the porous plate body part 269, and a perforated plate leg part ( 261,262,263,264,265,266,267,268).

Three or more perforated boards are sufficient. In the present invention, eight perforated boards are configured.

A space portion (d) is formed in the upper part of the perforated plate leg portion and the cap portion.

In the case of the first embodiment and the second embodiment, the filter housing part 600 is composed of an upper unit 300 and a lower unit 400, a first outlet 310 from the upper part of the inside of the filter housing, the The cartridge 100 to which the cap 200 is coupled, and the second outlet 410 are arranged in this order.

The material of the cartridge unit 1000 for water treatment of the present invention may be a metal, but it is preferable to use a synthetic resin material.

The present invention is used as a cartridge unit 1000 for water treatment, four protrusions are formed radially in the vertical direction of the cartridge 100 containing a filter medium therein, a hole is formed in the upper center of the cap, and a separate hole is provided on the side. more composed.

Four protrusions are ideal, but two or three protrusions can have a significant effect.

If there are no protrusions on the top and bottom of the cartridge 100, the water pressure is strong or even a small movement due to the operation movement during consumer use causes deterioration of function (reduction of flavor and deterioration of filter media).

That is, when the cartridge 100 is moved, water enters the hole of the cartridge 100 and the filter medium is not discharged, so that the operation becomes inoperable.

That is, since the treatment water pressure directly strongly contacts the lower end of the cartridge 100 , the cartridge 100 itself can move, causing a decrease in function.

In the case of Figure 3a in the present invention, tap water moves from the bottom to the top.

It is called bottom-up, and it is installed in the shower and the direction of water flow is bottom-up.

Water flows upwards from the bottom of the shower head.

In the case of Figure 4a, the water flow moves from the top to the bottom when it is directly mounted on the faucet.

As it is installed in the faucet, the direction of water flow is top-down.

Water flows downward from the top of the filter housing unit 600 mounted to the faucet.

In the case of FIG. 3A or 4A, if the cartridge 100 mounted inside the filter housing 600 moves even a little, a serious malfunction occurs.

The reason is that when the cartridge 100 moves inside the filter housing 600, the hole (0.6 ~ 0.9 mm) in the cap 200 at the upper part of the cartridge 100 moves, so that it is necessary for smooth inflow of water and discharge of the filter media. It causes a disturbance. As a result, the discharging of the molten media is obstructed and the fragrance is not produced or is very weak.

In the present invention, the dissolution of vitamin C of 60% or more of the filter media used as an example is reduced, resulting in dysfunction.

Therefore, insertion support protrusions 120, 130, 140, 150, 220, 230, 240, 250, 125, 135, 145, 155, 225, 235, 245, 255 are required to firmly fix the upper and lower portions so as not to swing.

Insertion support projections (120,130,140,150,220,230,240,250,125,135,145,155,225,235,245,255) may be configured on the upper end of the cap, but may be configured in the upper and lower portions of the cartridge 100 .

The case of the cartridge 100 is separated and may consist of the upper part of the case and the lower part of the case.

In general, it is good to divide the cap 200 and the case 100 .

The flow chart of the fluid inside the filter housing unit 600 and the cartridge 100 outside is as follows.

The water to be treated in red between the cartridge 100 and the inside of the filter housing 600 enters the first hole 110 (black) and reacts with the filter media inside the cartridge 100, the central portion of the upper part of the cap The filter media flows out through the shower head 700 by flowing out through the first hole part 110 (light green color) configured in the .

Referring to FIG. 3B, it is as follows.

Water flows into both the first hole part 110, which is the lower hole, and the second hole part 210 in the central part of the cap, and the filter media flows out. In (black), the flow (c) of the insert in the cartridge, which is the inflow of water, is large. Here, there is a small amount of media outlet flow (b') at the same time.

There is a large amount of filter media draw-out flow (b) that flows out to the central hole (yellow green), which is the second hole portion 210. Again, there is a small amount of insert flow (c') here as well.

4A and 4B will be described as follows. It is a flow chart of a fluid inside the filter housing 600 and outside the cartridge 100 .

It is to be installed in the faucet 2000 so that water flows from the faucet 2000 to the cartridge unit for water treatment.

It flows into the shower through the nozzle 750 connected to the shower.

The inflow water marked in red from the upper part flows into the second hole part 210 (yellow green), reacts with the filter media inside the cartridge 100, and flows out to the first hole part 110 (black) configured in the upper part of the cartridge 100 do.

Water flows out and flows in both the first hole part 110 as the lower hole and the second hole part 210 as the central hole, but in the case of top-down depending on the flow rate and flow direction of tap water, the amount of water flowing into the second hole part 210 (yellow green) is The cartridge insert flow (c) is large, and there is a small amount but small media withdrawal flow (b') at the same time.

To the first hole portion 110, the filter media withdrawal flow (b) is large and small at the same time, but there is a small insert flow (c') at the same time.

In addition, in the case of top-down, since the water pressure strongly blocks the hole in the cap part of the cartridge 100 vertically, the perforated plate part 260 to reduce the water pressure must be configured in the upper part of the cap part of the cartridge 100 only when the cap part of the cartridge 100 is configured A water film does not occur in the second hole portion 210 .

In Figures 5a and 5b, the cap portion 200 has a structure in which eight legs of the perforated plate portion 260 are attached to the upper portion of the cap portion 200 or attached by an interference fitting method.

In the case of top-down, when tap water continuously flows from top to bottom, a water film is formed, resulting in dysfunction.

When water pressure is continuously applied strongly, a thin water film is formed on the upper cap part 200 .

As the water pressure is stronger, the collision between the incoming water and the outflow water occurs, and when the balance is reached at some point, the formation of a water film that blocks the air bubble hole is prevented due to the above configuration.

While the perforated plate body 269 configured in the perforated plate 260 blocks tap water from being directly supplied strongly, the water flowing into the perforated leg parts 261 to 268 is inserted into the second hole 210, and the water screen is closed. to prevent it from forming.
