Abstract

PURPOSE:To simplify operation, by changing over the discharge of purified water and that of raw water while also performing the stoppage of a water flow in the same operation as the abovementioned change-over operation. CONSTITUTION:Not only a change-over means is operated but also a water stoppage means is operated by operation input. That is, a cartridge 3 is attached to a spigot 10 so as to be positioned below the horizontal pipe part of said spigot 10 and the four-stage changing-over of the stoppage of water, the discharge of purified water, the shower like discharge of raw water and the straight discharge of said raw water is enabled while various water discharge states and a water stoppage state can be obtained only by the operation of a lever 2 corresponding to the use of water. Further, because the water stoppage state is elapsed on the way of the changing-over from the discharge state of purified water to that of raw water, the wastefulness of water during the changing-over is eliminated and economical efficiency is achieved and the life of a filter material 7 is extended.

Description

Detailed Description of the Invention [Technical Field] The present invention relates to a water purifier that removes unpleasant odors and tastes caused by residual chlorine in tap water and removes colloidal iron powder and fine dust that have settled in water. Place it on the tip of the water faucet 1)
(This is related to a simple water purifier that is old and used.

V Background Art 1 As the above-mentioned simple water purifiers, there have conventionally been those shown in FIG. 1 and those shown in FIG. 2. Figure 1 shows that for small children, there are 2 parts or 1 part of the water in the faucet.
It houses a cylindrical cartridge containing 3 cartridges,
Water flowing from the faucet is guided into the cartridge 3 from above and is purified by contacting with the filter medium 7, and this purified water is passed through the passage between the outside of the cartridge 1 (11) and the inner surface of the container into the container. The water is discharged from the water outlet 9 led out from the second part, so the water discharged is always purified water that is in contact with the filter 47, and the water can be stopped by turning the faucet. In this case, unless the water purifier is removed from Snake 1, the water released is always purified water, so there is no need to purify the water.In other words, the purification effect of wave phase 7 is effective even when the water is not used for drinking. This would shorten the life of the filter medium 7.The one shown in Fig. 2 was disclosed in Publication of Utility Model Publication No. 53-2 =412 ci, and according to this, the life of the filter medium 7 would be shortened. Switch between the two channels: one that leads the water from the TL to Carlitz 3, where the filters 4 and A7 are housed, and then flows to the water outlet, and the other that channels the water directly to the water outlet. Since the switching valve 7 () is set (liii), the switching valve 70 can be operated by operating the lever 2 to switch between the two waterways, and raw water that has not been turned into sludge can be directly discharged when purified water is not required. Therefore, the drawbacks of the conventional example described above are eliminated. However, in this case, the water discharge is controlled by the faucet, and the lever 2 is used to control whether purified water or raw water is discharged. , The repetition is confusing.

[Objective of the Invention 1 The present invention has been made in view of the above points, and its purpose is not only to be able to switch between discharging purified water and discharging raw water, but also to provide an operation for this switching. To provide a water purifier which is easy to manufacture because water can be stopped with the same operation.

This prevents the tip of the elastic piece 21 from being inadvertently pushed and being disengaged from the engagement piece 25. Note that the opening 29 formed on the surface of the cover G faces the transparent window 3° 7 of the cartridge 3. Cartridge)
3, pull out the cover 6 to remove it, and then sandwich the ends of both elastic pieces 21 of the cartridge 3 and bend them inward to separate the elastic pieces 21 and the engaging pieces 25. This is done by removing the old cartridge 3 by dividing the engagement by i+1 and installing a new cartridge 3. Since the screws 11 and the like are not required, replacement work is easy. Note that 72 to 76 in the figure are all O-links.

However, in this water purifier, the cartridge 3 is placed under the horizontal pipe section of the water faucet 10, and the water purifier is placed in the water tap 10. The lever 2 can be used to switch between water stop and water discharge without turning the faucet 10 each time.When the lever 2 is placed at the spout position shown in Fig. 7, the rotary valve opens as shown in Fig. 11.

Water flows from the second inlet 54 through the communication hole 16 into the car 19 of the back JJ, and residual chlorine is removed by the suction R'f action of the filter (47). At the same time, the colloidal iron powder that settles into the water as it passes through the filter) is removed by the silver attached to ilA', +J7. After removing all the dirt, follow the connection hole 17' (1st iAt l11. of book I4-1).

Approximately 211' of the entire ring 3; this means that the contact time between the filter A7 and the water is longer, and the effect of chlorine adsorption on the ring 3 is increased. Not only is it on sale, but it's also a good idea to know all the details of Kartlitz 3. Also, because the passageway blood cutter is smaller, there is no possibility of a short bus in which water passes through only a portion of the filters 4 and 47.
A7 is designed to have a purifying effect, even though it may come into contact with water. The purified water returning to Kimoto 1 from Kar 1 Ritstu 3 moves further downwards from the passage above, so that after this the purified water returns to the bottom of Kar 1 Rin:) 3 1)' The second plug located in L:) 6 is directed toward the woody plant 1 side, which makes it difficult for water to accumulate inside the cartridge 3. Since the water from which chlorine has been removed becomes a breeding ground for bacteria, this is probably due to the N:3 biological effect.

Next, when the lever 2 is moved forward one step from the water stop state indicated by i''+ij to the position shown by c in FIG. At the same time as communicating with the inflow +1111, the discharge 1"55 or the 2nd
The water from the inflow port 115 is connected to the outflow port 115, and for this reason, the water from the inflow port 111 passes through the outlet port 55 and the second outflow port 15 to the peripheral portion of the ring-shaped bulkhead portion 45 -1-+f+iL. After that, it is released from the small holes 12 of the water discharge plate 4 in the form of a shower-like flow.

At this time, water does not flow to the Kartlitz 3 side.

When the lever 2 is moved forward from the shower-like water discharge state to the position shown in Fig. 7-2, the first introduction 1-l at the rotary valve 5 (as shown in the figure is small).
Although the outlet port 55 of the rotary valve 5 is in communication with the first outlet i2+14 instead of the second outlet l'15, the iQ Person] The water from 2111 is located directly below it, the first! Afi! This jet flow flows into the flow rib 43 and the rectifying wire mesh 441 after the flow velocity is weakened by hitting the J1j piece 46 of the 1A wall 4'4' 45. The water flows down and is discharged from the water outlet 41. At this time, as the water flows down the first outlet 14, the force A' in the connecting hole 17 connected to the first outlet 14 decreases. For this purpose, the water accumulated in the connection hole 17, which is in a state where germs are likely to breed because chlorine has been removed, is sucked out and extracted. Also at this time, water does not flow to the cartridge 3. In addition, when discharging raw water in the form of a shower or directly discharging water, use the thin hanging piece 5 of the water stopper seal 12 (first introduction l) 53.
Because it fits inside, it is in the position shown by the broken line in FIG.

In this way, the illustrated water purifier can stop water, discharge purified water,
4. Shower-like discharge of raw water and direct discharge of raw water
It can be switched in stages, and can be switched between various water discharge states and water stop states by simply operating the lever 2, depending on the purpose of the water. In addition, when switching from discharging purified water to discharging raw water, there is a water stop state in the middle, so no water is wasted during this switch, which is not only economical but also , this also leads to an extension of the life of the wave phase 7.

In addition, regarding the spraying of purified water, it is not a shower-like water spray.
Only 1α water is used, considering that shower-like water is generally used for washing dishes, and purified water used for drinking water is not released as shower-like water. .

1 Effects of the Invention 1 As described in 2 above, in the present invention, it is possible to switch between discharging purified water and discharging raw water, and it is possible to use purified water or raw water depending on the purpose of the water. 52, you can switch between water stops and water discharge, and between purified water and raw water. Both operations can be performed extremely easily.
