Description

  In the present invention, raw water such as tap water and well water is subjected to a purification treatment that satisfies the water quality standard as drinking water in a short time inside the container body, and the portable water can be directly consumed from the container body. It relates to a type water purifier.

  Two types of water purification systems are known for general portable water purifiers. The first is to collect raw water in a water purifier storage container, pressurize the raw water through a pump means, and bring it into contact with a purifier such as activated carbon or zeolite contained in the container to adsorb chlorine or odor. In addition to removing off-flavors and filtering and purifying fine fungi and microorganisms through hollow fiber membranes, the second is from Japanese paper or non-woven fabric that contains a purifier such as activated carbon inside the water purifier storage container. A bag body or a water permeable container made of a wire mesh is directly immersed, and the raw water entering and leaving the bag body and the water permeable container is brought into contact with a purifier and purified using gravity. Most of the proposed portable water purifiers use these methods.

  As specific examples of the first water purification method, for example, JP-A-6-335671 (Patent Document 1), JP-A-10-137740 (Patent Document 2), JP-A 2000-301139 (Patent Document 3). JP-A-2003-311263 (Patent Document 4) and the like. Specific examples of the second water purification system include, for example, JP-A-62-149395 (Patent Document 5) and JP-A-62-2. 227489 gazette (patent document 6), patent 3495993 gazette (patent document 7), etc. can be mentioned.

  According to Patent Document 1, a hollow cylindrical container body with a bottom, which is a water storage container, is made of a thin, soft material made of various synthetic resins, and a connectable / detachable water purification unit is connected to the opening of the container body. Then, the container body filled with the raw water is squeezed with a finger to push the raw water toward the water outflow opening of the water purification unit. In the middle of this extrusion, raw water flows while contacting the hollow fiber membrane and activated carbon, and filtration and adsorption purification processes are performed to produce purified water. Although the water purifier proposed by patent document 4 is the same as patent document 1 and a water purification system, the order of the flow of the raw | natural water which flows through activated carbon and a hollow fiber membrane is reverse.

  Further, according to Patent Document 2, the container body is formed in a bellows shape, and the handle body is operated by hand by taking advantage of its elasticity, so that the container body is expanded and contracted, and the intake valve and the drain valve are switched as necessary. The raw water is taken from the water source or the purified water is drained.

  On the other hand, according to Patent Document 3, the upper container and the lower container can be separated by screw fitting, and the pump lever protrudes from the upper part of the upper container. Moreover, it has the purified water discharge nozzle connected to the pump part of an upper container in a water-sealed state. A raw water inlet is formed in the lower container, and a water purification cartridge is stored in the lower container. A raw water introduction hose is inserted into the raw water introduction port, one end of the hose is connected to the raw water inlet of the cartridge, and the other end of the hose is submerged in the raw water to operate the pump lever. The raw water is introduced into the water purification cartridge through the hose, and after the raw water is purified, the raw water is discharged from the purified water discharge nozzle.

  In Patent Document 5, water purification is performed by immersing a water-purifying pack in which water-permeable substances such as activated carbon and ion-exchange resin are wrapped in a water-permeable film-like material made of, for example, Japanese paper or nonwoven fabric, in water. . In addition, in the same patent document 5, when using the pack, the adsorption efficiency of chlorine is increased by shaking the pack immersed in raw water in a container such as a kettle or stirring the tap water in the container. Have been described.

  Patent Document 6 also purifies water by storing a substance having a water purifying ability in a bag made of non-woven fabric and immersing it in raw water. A water purification agent containing activated carbon and L-ascorbic acid and / or L-ascorbate is used as a substance having water purification ability at this time. Moreover, in the said literature 6, since the bag which consists of a nonwoven fabric containing the substance which has the said water purification ability will just float up in water and purification efficiency will become low, the said bag body is made from a spherical metal net body. It is housed in a settling tool, which is put into raw water and settled to purify the raw water.

  The water purifier of Patent Document 7 is composed of a bottle-type container body having a shape similar to that of a PET bottle, and a capsule having a water-permeable opening in the whole that can be stored and taken out from the bottle-type container. The capsule is formed into a perforated cylindrical shape having a canopy portion and a bottom portion using a metal plate, leaving the seam of the metal plate as a crack, and in a natural state where no force is applied from the outside, the capsule is a bottle. It has a size that cannot pass through the mouth opening of the mold container body, and is pressed inward against its elasticity to reduce the width of the crack and pass through the mouth opening. In this capsule, the capsule containing a water purification agent that purifies and activates raw water is immersed in the raw water in a bottle-type container to make purified water. Since the capsule in the bottle-type container is larger than the shed, it does not come out of the shed and is securely held in the bottle-type container.

  Here, since the portable simple water purifiers proposed by Patent Documents 1 to 4 all use the pump function, the structure of the water purifier inevitably tends to be complicated, and the number of parts also increases. Inevitably, there are many complicated assembly and disassembly operations, which tend to lead to an increase in production costs, and have a large impact on product prices. In that respect, since the portable simple water purifier proposed by Patent Documents 5 to 7 has a simple structure, the number of parts is small, and material costs and production costs can be kept relatively low. In addition to these problems, for example, in the portable simple water purifier of Patent Document 1, all the components are disposable due to its configuration, and further improvement is desired when considering the reuse of resources. .

  Incidentally, it is generally known that increasing the contact between the water purification agent and the raw water is effective for shortening the water purification time. Therefore, according to Patent Document 5, for example, in order to increase the adsorption efficiency of residual chlorine in the raw water, it is preferable to shake the water purification pack immersed in the raw water or to stir the raw water. However, in the portable simple water purifier as in Patent Document 5, when the water purification pack is shaken or the raw water is to be stirred, the lid of the container is removed and the stirring tool is inserted into the raw water from the outside. It is necessary to operate a stirring tool, and there is a high possibility that raw water will be scattered around. On the other hand, for example, the bottle-type portable water purifier of Patent Document 7 is a plastic bottle type with a small drinking mouth, so that the stirrer can be used for the capsule for purified water contained in the raw water inside the lidded container. Not only is it difficult to shake or stir raw water itself, but it is difficult to deform the capsule with external force even when trying to take out the capsule from the container body, making it completely disposable .

  On the other hand, in the same manner as described in Patent Document 7, when you want to drink purified drinking water, especially in an office, study, study room, etc. in an urban area, you can go to a nearby shop and drink drinking water. Recently, there are increasing cases of drinking tap water drawn indoors directly as drinking water. However, the amount of water that can be drunk at the office or home at this time is at most about a cup or teacup, and you can not drink more than that, and the remaining water will remain on the desk etc. until the next time you drink it. Often left on top. Moreover, if you want to drink, you will always want to drink.

  In recent years, the development of purification technology has been remarkable, and even if tap water is used for drinking, there has been little impact on health. However, many purification water, especially tap water, treated in large quantities by large purification facilities Is chlorinated, and there is a concern about the generation of trihalomethane, which is said to be carcinogenic in the purified water. Also, the musty odor due to the metabolism of microorganisms such as algae that grows under eutrophication of lakes and rivers that are water sources, and the odor of calcium emitted from residual chlorine is not suitable for drinking. For this reason, it is necessary to further purify the tap water that is drunk with the glass as described above, to further reduce the amount of residual chlorine, and at the same time to remove microorganisms and efficiently eliminate unpleasant odors in a short time.

  The present invention provides a cup-type portable water purifier with a simple purifying mechanism that can be used in place of a cup or teacup placed in an office, study, study room, etc., and can be purified in a short time. The purpose is to do.

  The present inventors have made various studies in order to achieve the above object. In a water purifier that is about the size of a cup, in order to increase the purification speed and purification efficiency, the surface area of the water purification agent itself contained in the water purifier is made as large as possible, and tap water is quickly and efficiently applied to the surface. Need to contact. In addition, the water purification agent itself is inexpensive and must adsorb chlorine and odors quickly and efficiently. As the water purification agent satisfying such requirements, activated carbon, ion exchange resin, and the like are suitable. These materials can be formed into various shapes. For example, it can be formed into powder, fine particles, fibers, or blocks having different sizes. However, when it is formed into a powder, it is difficult to uniformly disperse it in water, and its handling becomes complicated. Moreover, when it is block shape, a contact area with water becomes small. Considering such circumstances, it is preferable to be fine particles.

  By the way, if particulate activated carbon etc. is directly immersed in tap water put in the container body, it will float on the top, not only will the purification be unevenly distributed, but also if you try to drink purified water directly from the container The fine particles of activated carbon get into the mouth with clean water, and each time you drink it, you feel uncomfortable. However, as described in Patent Document 6, after storing the particulate water purifier in a bag of paper or non-woven fabric, even if the bag is immersed in tap water, the water does not fall down. When trying to submerge, it just floats in the water as well, and like the water purifier of the said patent document 6, it has to add an extra thing like a settling tool which is not related to purified water.

  Furthermore, simply immersing a water purification pack containing a water purification agent such as activated carbon into the water in a stationary container body will not cause the flow of water, so the entire water in the container body will be used as a water purification agent. It becomes difficult to contact. In order to make this contact efficiently, as described in Patent Document 5, the water purification pack is actively shaken in the purified water or the water is stirred to promote the flow of water into and out of the pack. It is desirable. Here, a general water purifier for ordinary home use is generally used in a state where the container body is largely left stationary.

  As described above, the portable simple water purifier of the present invention is based on the premise that the shape and size of the cup and teacup are close to each other at home or at work. Since the container can be shaken (shaken) with the hand, water and the water purifier can be efficiently brought into contact with each other. However, since the water purifier itself is small, it can be easily held and shaken, but the water in the container body can easily spill out from the drinking mouth. To prevent this, it is necessary to attach a removable and highly sealable lid to the water purifier. Shaking here means moving the water purifier in your hand.

  Furthermore, it is desirable to use a container in which the particulate water purification agent accommodated in the container body does not move inside and outside the container, that is, a water purification cartridge having a water permeable hole through which water can be permeable and water purification agent cannot pass. This water purification cartridge can be composed of a rigid body or a mesh material such as a somewhat rigid paper or nonwoven fabric. Thus, these water purification cartridges can freely move inside the water purifier main body. For example, when the water purification cartridge is made of a rigid body, the water purification cartridge can be freely moved within the container main body of the water purifier. The water purification cartridge collides with the inner surface of the water purifier main body (container main body), and both the container main body and the water purification cartridge are easily damaged. For example, when the water purification cartridge is composed of a rigid container or nonwoven fabric, the water purification agent in the cartridge moves around with the movement of the water purification cartridge, so that the inside and outside of the water purification cartridge are exchanged through the mesh by a shaking operation. The amount of water that should be transferred does not reach the desired amount, and the purification tends to be uneven, and the shaking time becomes longer until the water is evenly purified.

  Therefore, in the present invention, it is important to fix the water purification cartridge to a container body which is a water purifier body. If the water purification cartridge is a rigid body as described above, it is possible to take out and discard only the water purification agent contained in the cartridge, but normally replace the entire cartridge while keeping the cartridge and the internal water purification agent integrated. A possible configuration is adopted. In order to make the entire cartridge replaceable, for example, the cartridge itself may be formed of a thermoplastic synthetic resin that is easy to mold and rigid.

  By the way, as described above, when the water purifier is held in the hand and shaken for the required time, and the water purifying cartridge fixed to the container main body, which is the main body of the water purifier, is moved together, the water purifying agent stored in the water purifying cartridge. It is desirable to be able to move around the cartridge freely to some extent. At this time, the particulate water purification agent stored in the cartridge is directly put into the cartridge in a granular form, and the particulate water purification agent is once enclosed in a bag body made of a mesh material, and the bag body is cartridge There is a mode to be accommodated. In any aspect, it is necessary that the water purification agent accommodated in the water purification cartridge can freely move around within the cartridge to some extent. However, it has been found that as long as the water purifier can move freely in the water, the purification is not necessarily performed efficiently.

  The present invention has been developed by paying attention to these points. That is, as described above, if the amount of the water purification agent in the cartridge is too large, free movement of the water purification agent is suppressed, whereas if the amount of the water purification agent is too small, the contact area with water itself is reduced. Thus, the desired water purification treatment cannot be performed within the desired time. Therefore, many experiments including this point were repeated. As a result, it was found that as a factor affecting the efficiency of this water purification treatment, in addition to the filling rate of the water purification agent in the water purification cartridge, the shaking time and shaking speed are greatly related. As a result of such various studies, the present invention has finally been reached.

The basic configuration of the present invention includes a covered cup-type container main body having a water storage part, a water purification cartridge containing a water purification agent, and a cartridge holder for fixing and holding the cartridge. A portable simple water purifier for purifying water flowing in a container, wherein the water purification cartridge has a water passage hole, and the water purification cartridge can be exchanged between the cartridge holder and the cup-type container main body. It is characterized by having fixing means for clamping and fixing.

  In the present invention, it is important that a sealing material is interposed between the upper end opening of the container main body and the lid, and the water purification cartridge is constituted by a rigid hollow cylinder having a bottom, It is preferable that the body has a plurality of water passage holes on the peripheral surface of the body, and the water purification agent is housed inside the hollow cylinder through a mesh material. The said mesh material is good to be comprised from mesh materials, such as a net | network thing, a woven / knitted fabric, and a nonwoven fabric which have a mesh below the particle size of a granular water purifier. Moreover, it is desirable that the water purification agent is accommodated in a bag made of the mesh material, and the bag is accommodated in the hollow cylinder.

  Further, the portable simplified water purifier according to the present invention has a protrusion at the bottom of the container main body, a recess at the bottom of the water purification cartridge, and when the protrusion and the recess are fitted. It is preferable that the bottom of the container main body positions and supports the water purification cartridge from below. Furthermore, the container main body preferably has a holder holding part for holding the cartridge holder, and the cartridge holder has a cartridge holding part for inserting and holding the water purification cartridge from below.

  Furthermore, when the upper end opening of the container body is closed by the lid body, the lower end surface of the lid body is in close contact with the upper end surface of the cartridge holder, and the water purification cartridge is inserted into the lid body and the container body via the cartridge holder. It is preferable to constitute so as to be sandwiched and held between the two. The water purification cartridge may have a cartridge lid, and a plurality of water passage holes may be formed in the cartridge lid. The water passage hole can be formed on the peripheral surface as well as the upper surface of the lid. The holding position of the container body and the cartridge holder is preferably 5 mm or more away downward from the upper end opening of the container body, and further the upper end height of the water purification cartridge accommodated and held in the container body. However, it is good that it is set lower by 5 mm or more downward from the upper end opening of the container body.

  When the filling rate of the particulate water purification agent in the water purification cartridge is smaller than 20% by volume, the ratio of the amount of the water purification agent to the amount of water in the container body is small, the absolute contact area with water is small, and the purification time is small. Extremely long. Experiments have shown that when a person holds the water purifier in his hand and continues to shake at a speed of 100 r.p.m, it can only last for 1 minute. When the filling rate of the particulate water purification agent is 20% by volume or less, it is difficult to satisfy the water quality standard as drinking water for all the water even with a shaking time of 1 minute. Further, if the shaking is continued for a long time, the particulate activated carbon is liable to be damaged and the production of fine powder becomes intense. On the other hand, if the filling rate of the particulate water purification agent exceeds 90% by volume, the movement of the particulate water purification agent in water becomes dull and it becomes difficult for the water to freely come into contact with the water purification agent, so the contact area with water is also limited. Even if the filling rate is increased beyond 90% by volume, the purification amount of water is reduced. According to experiments, the most ideal filling rate is 60% by volume when limited to the reduction rate of residual chlorine.

When the water purification agent is stored in the water purification cartridge via the bag body made of the mesh material, the mesh of the bag body containing the water purification agent needs to be smaller than the particle size of the water purification agent. By the way, in this embodiment, the particle diameter of the activated carbon which is a water purification agent is 0.3 mm, and the first opening of the net woven with synthetic fiber filaments is 0.2 mm square. If the water purifier bag mesh is larger than the particle size of the water purifier, the water purifier moves out of the bag and mixes with the water in the container body of the water purifier. In addition, a large number of water passage holes are formed on the peripheral surface of the water purification cartridge made of a hollow cylinder so that water can easily pass inside and outside. The raw water in the container body passes through the water passage hole on the peripheral surface through the inside and outside of the water purification cartridge, and efficiently contacts and purifies the water purification agent in the hollow cylinder. At this time, when a plurality of water passage holes are also formed in the canopy portion of the water purification cartridge, the water crosses the cylinder in the horizontal direction and the vertical direction through the water passage holes of the peripheral surface or the canopy portion. Flowing and moving the granular water purifier in multiple directions, the chance of contact increases and more efficient purification is achieved.

  There is also a correlation between the shaking speed of the main body of the portable container, the reduction rate of free residual chlorine in the raw water, and the amount of fine powder of the water purification agent. For example, the filling rate is 60% by volume or more, and the rotation speed of shaking is 100 rpm. If it carries out above, the free chlorine removal rate will be 80% or more. On the other hand, if the filling rate is 60% by volume or more and the rotational speed of shaking is 200 r.p.m or less, the amount of particulate activated carbon fine powder flowing out into the water purification container is 2 NTU or less. When the water purifier is activated carbon (GW 10/32), when tap water is used for drinking, the upper limit of the water quality standard for drinking water is set to 2 NTU.

  In view of the above, in the portable simple water purifier of the present invention, the filling rate of granular activated carbon is more preferably 60 to 90% by volume, and the shaking rotation speed of the container body is 100 rpm or more, 200 rpm. Hereinafter, the free chlorine removal rate when the shaking time is 30 to 60 seconds is 66.0 to 85.0%, and further, the portable container is shaken for 30 to 60 seconds at a shaking rotation speed of 200 rpm. When the generated amount of activated carbon is damaged and fine powder flows out is 2 NTU or less, it does not feel uncomfortable even if it is used for drinking.

  In the present invention, the limit of the time that a person can shake with a water purifier in his / her hand without feeling fatigue is 60 seconds, but if the generation of fine powder and the shaking time are not considered, It is possible to increase the free chlorine reduction rate as the shaking time is lengthened. In order to increase the contact area with water, it is necessary to increase the shaking rotation speed of the water purifier. However, if the shaking rotation speed is increased too much, the internal water purifier will move violently and be damaged, and the generation of fine powder will be remarkable. Become.

  On the other hand, in addition to the above configuration, the portable simple water purifier according to the present invention is configured such that the holding position of the container main body and the cartridge holder is separated by 5 mm or more downward from the upper end opening of the container main body, or the container When the upper end height of the water purification cartridge accommodated and held in the main body is set lower by 5 mm or more downward from the upper end opening of the container main body, the lips and the nose will The cartridge will not be touched.

  The portable simple water purifier 1 according to the illustrated embodiment includes a container body 10 having a cup shape, a water purification cartridge 20 housed and fixed in the container body 10, and a cartridge that holds the upper end of the water purification cartridge 20 from above. It has a holder 30 and a lid 11 that is removably fitted into the upper end opening (drinking mouth) of the container body 10 by a bayonet mechanism. A seal ring 12 is interposed between the lid 11 and the upper end opening of the container body 10 to maintain water tightness. The said container main body 10 is comprised, for example from AS resin, and protrusion 10a 'protrudes along the inner peripheral surface of the upper end opening (drinking mouth), and the protrusion which has a mountain shape with the lower surface in the center of the bottom face of the container main body 10 The part 10b bulges upward. For example, ABS resin is used as the material of the lid 11. The material used for the cartridge holder 30 is MBS resin. However, the material of each member in the present invention is not particularly limited to the illustrated example as long as it is a thermoplastic resin.

  In the present embodiment, the lid 11 is fitted into the upper end opening of the container body 10 from the inside by a bayonet mechanism, but may be fixed by screwing. According to the illustrated example, the four protrusions 10 a ′ are formed in the upper end opening of the container body 10 as described above, and the four protrusions 10 a ′ are formed on the outer peripheral surface of the fitting portion of the lid 11. A groove 11a having a key shape is formed to fit each. When the lid 11 is fitted into the upper end opening of the container body 10, the lower end of the lid 11 is in close contact with the upper surface of a first ring 31 (to be described later) of the cartridge holder 30. A bulged mountain-shaped protrusion 10 b protrudes upward from the bottom of the container body 10.

  The water purification cartridge 20 includes a cartridge main body 21 made of a bottomed hollow cylinder and a cartridge lid 22 attached to the upper end opening of the cartridge main body 21. The cartridge main body 21 has a vertical lattice portion 23 and a horizontal lattice portion 24 adjacent to each other along the circumferential surface thereof and arranged with a phase difference of 180 °. The vertical lattice portion 23 has a plurality of vertical rectangular first openings (water passage holes) 23a, and the horizontal lattice portion 24 has a plurality of horizontal rectangular second openings (water passage holes) 24a. Yes. Further, a ring-shaped flange portion 21 a is projected from the upper end opening of the water purification cartridge 20 along the outer peripheral surface thereof.

  The upper surface of the ring-shaped flange portion 21a is a horizontal surface for holding the cartridge holder 30 from below. In addition, a recessed portion 21b for fitting the tip of a mountain-shaped protruding portion 10b bulging to the bottom of the container body 10 is formed at the center of the bottom surface of the bottom of the water purification cartridge 20. Four engaging holes 21c having a phase difference of 90 ° are formed in the peripheral edge of the water purification cartridge 20 above the ring-shaped flange portion 21a. The cartridge lid 22 will be described later in the engaging holes 21c. The engaging claw 22b is engaged to integrate the cartridge main body 21 and the cartridge lid 22 together.

As shown in FIGS. 4 and 5, the cartridge lid 22 has a shape that approximates an inverted cup, and the lower end opening has the same shape and the same size as the upper opening of the cartridge body 21, and the opening Four engaging claws 22b are formed at four positions corresponding to the formation sites of the four engaging holes 21c formed in the cartridge main body 21 along the periphery. The engaging claw 22b includes a vertical piece 22b 'extending vertically downward from the inner surface of the peripheral edge of the lower end opening of the cartridge lid 22, and a claw piece bent from the lower end of the vertical piece 22b' and projecting radially. 22b ". In order to close the upper opening of the cartridge body 21 with the cartridge lid 22, the engagement holes 21c corresponding to the engagement claws 22b are made to correspond to each other and the lower end opening of the cartridge lid 22 is opened. Is pushed down in a state of abutting against the upper opening of the cartridge body 21, the vertical pieces 22b 'are elastically deformed, and the engaging pieces 21b "of the engaging claws 22b correspond to the corresponding engaging holes 21.
The cartridge main body 21 and the cartridge lid 22 are engaged and integrated with each other.

  Thus, before the cartridge main body 21 and the cartridge lid 22 are engaged, granular activated carbon or ion exchange resin as a water purification agent is accommodated in the cartridge main body 21. In the present invention, when the water purification agent is put into the cartridge main body 21 in the granular state, the water passage hole formed in the cartridge main body 21 is larger than the particle size of the water purification agent, so the water purification agent moves out of the cartridge main body 21. For this purpose, the water purification agent is not shown in the figure, but is stored in a net bag having an appropriate mesh obtained by using, for example, a synthetic resin monofilament, and is stored in the cartridge body 21. The volume of the bag body at this time and the filling amount of the water purification agent to be stored are determined in consideration of the volume of the cartridge main body 21 and the filling rate of the bag body.

  In the present embodiment, two water passage holes 22 c are formed in the top plate of the cartridge lid 22. This water passage hole 22c also has the first and second openings (water passage holes) 23a, 24a of the vertical lattice portion 23 and the horizontal lattice portion 24 formed in the cartridge main body 21, and the water contained in the container main body. It becomes a water flow opening, complicates the flow of water, and water comes into contact with the water purification agent from multiple directions, leading to an improvement in purification efficiency. In the present invention, the water passage hole 22c formed in the canopy portion of the cartridge lid 22 can be eliminated.

  As shown in FIG. 6, the cartridge holder 30 is provided with a first ring 31 and a second ring 32 at a desired interval in the vertical direction, and there are five between the first and second rings 31 and 32. The connection rod 33 is connected. The connection by the connection rod 33 may be linear, but the connection positions of the connection rods 33 are shifted with a slight phase difference between the first and second rings 31 and 32 to connect the connection rods 33. . In other words, the connecting rods 33 are attached so as to be twisted between the first and second rings 31 and 32. By connecting in this way, even if a slight variation occurs in the distance between the first and second rings 31 and 32, it can be accepted.

  The outer diameter of the first ring 31 is substantially equal to the inner diameter of the upper end opening of the container main body 10, and the ring-shaped protrusion 10 a protrudes along the inner peripheral surface of the upper end opening of the container main body 10 on the outer peripheral surface thereof. Are provided with two ring strips 31a and 31b. The ring-shaped protrusion 10a is a holding portion of the cartridge holder 30 in the present invention, and the ring strips 31a and 31b are cartridge holding portions in the present invention. On the other hand, the outer diameter of the second ring 32 is equal to the outer diameter of the upper end opening of the water purification cartridge body 21, and when the upper end of the water purification cartridge is inserted into the second ring 32, the lower end surface of the second ring 32 is The cartridge main body 21 is supported from below the cartridge holder 30 in close contact with the upper surface of the ring-shaped flange portion 21 a protruding along the outer peripheral surface of the upper end opening of the cartridge body 21.

  Now, in order to fix and hold the water purification cartridge 20 to the container body 10, first, the cartridge lid 22 side of the cartridge body 21 is inserted through the second ring 32 of the cartridge holder 30 toward the first ring 31, The holder 30 is supported from below by the water purification cartridge 20. Next, in this state, the water purification cartridge 20 and the cartridge holder 30 are inserted together through the opening of the container body 10. At this time, when the bottom central portion of the water purification cartridge 20 is inserted toward the bottom central portion of the container main body 10, the recessed portion 21 b formed in the bottom portion of the water purification cartridge 20 is formed on the protrusion 10 b formed on the bottom of the container main body 10. The upper end part fits and supports the water purification cartridge 20 while automatically positioning from below.

Here, when the container body 10 is closed with the lid 11, as described above, the lower end surface of the lid 11 is in close contact with the upper surface of the first ring 31, and the bottom recessed portion 21 b of the water purification cartridge 20 is a portable simple type. The water purifier 1 is firmly supported from below by a protruding portion 10b protruding from the bottom of the container body 10 of the water purifier 1. That is, the water purification cartridge 20 includes the cartridge holder 3.
Positioned and fixed inside the container main body 10 with a top and bottom sandwiched between the lid 11 and the protrusion 10b formed on the bottom of the container main body 10 via 0. In the present embodiment, the protruding portion 10b at the bottom of the container body 10, the cartridge holder 30, and the lid 11 constitute the cartridge fixing means in the present invention. To shorten the water purification time, it is effective to shake the container in order to increase the contact with the raw water. However, in the conventional simple water purifier, the cartridge is not fixed and the container is often damaged.

In the present invention, the granular water purification agent is stored in the water purification cartridge 20 in a state of being stored in a mesh-like bag body that has water permeability but prevents passage of the granular water purification agent. Here, as a result of accumulating various experiments, as described above, it is important to shake (shake) the entire water purifier by hand in order to efficiently contact the water with the granular water purifier. At this time, it has been found that the filling rate of the water purification agent into the water purification cartridge 20 greatly affects the water purification efficiency. Therefore, the most characteristic configuration in the present invention is how to make the volume of the water purification cartridge 20, the size of the bag body, and the filling rate of the water purification agent stored in the bag body appropriate values. is there. Since the filling rate is relatively determined by the volume of the water purification cartridge 20 and the volume of the bag body, in the following description, this is simply referred to as the filling rate for the water purification cartridge 20.
Hereinafter, the present invention will be described in detail based on specific examples with reference to the accompanying drawings and tables.

[Specific Example 1 and Comparative Example 1]
# Implementation conditions Water purification agent: Activated carbon GW 10/32 with a particle size of 0.3 mm
Raw water used: Chlorine concentration 2.0ppm
Shaking rotation speed: 100r.pm
Shaking time: 30 seconds, 60 seconds, 120 seconds, 180 seconds Used bag body: A plain weave network woven with synthetic fiber filaments, the first opening is 0.2 mm
Square filling rate: 10 vol%, 20 vol%, 40 vol%, 60 vol%, 90 vol%, 95 bodies
product%

  Under the above implementation conditions, the average reduction rate of free residual chlorine was calculated based on the measurement results of three times for each condition. The results are shown in FIG. From the figure, when the shaking time when the free chlorine reduction rate exceeds 60%, the filling rate is 20 to 90% by volume when the shaking time is 30 seconds, and 40 to 90% by volume when the shaking time is 60 seconds. It can be seen that it is 10 to 90% by volume in 120 seconds. However, as described above, when the shaking time of the water purifier exceeds 60 seconds, a feeling of fatigue is felt, and it becomes difficult to shake more than that. Considering this point, it is reasonable to limit the shaking time to 30 to 60 seconds.

  On the other hand, when the filling rate is 10% by volume and 95% by volume, the reduction rate of free chlorine gradually increases as the shaking time is lengthened. It takes 180 seconds (3 minutes) to reduce the chlorine reduction rate to 60% or more, and it cannot be adopted at all.

[Specific Example 2 and Comparative Example 2]
The results of Specific Example 2 and Comparative Example 2 are shown in FIG.
The implementation conditions are the same as those in Example 1 and Comparative Example 1, and are the same as those in Example 1 and Comparative Example 1 except that GW10 / 32 was used as the activated carbon.

FIG. 8 shows that when the shaking time is 30 seconds and 60 seconds, if the filling rate is 20 to 90% by volume, the reduction rate of free chlorine greatly exceeds 60%. On the contrary, when the filling rate is 10% by volume, the reduction rate of free chlorine exceeds 60% for the first time when the shaking time is 120 seconds, but when the filling rate is 95% by volume, the shaking time is as long as 180 seconds. Even so, the free residual chlorine reduction rate finally reaches 60%.
As far as the specific examples 1 and 2 and the comparative examples 1 and 2 are seen, it is effective that the filling rate of the granular activated carbon is in the range of 20 to 90% by volume for the de-free chlorine treatment.

[Specific Example 3 and Comparative Example 3]
The specific example 3 and the comparative example 3 measured the relationship between the generation amount (NTU) of the fine powder of the water purifier (activated carbon) generated at the time of purification of tap water by the portable simple water purifier of the present invention, and the shaking time. . The working condition was that the amount of fine powder in raw water (tap water) was 0.1 NTU. The tap water is made of activated carbon every 8 seconds, 20 seconds, and 30 seconds with a portable simple water purifier in the above embodiment of the present invention, with the same filling rate as in the above-mentioned specific example 1 and comparative example 1. The amount of fine powder generated (NTU) was measured. The amount of fine powder generated (NTU) was measured three times for each filling rate, and the average value was defined as the amount generated (NTU). The results are shown in FIG. According to tap water quality standards, potable water must be 2 NTU or less.

According to FIG. 9, when the filling rate is 60% by volume or more, it can be seen that the water quality standard as drinking water is cleared.
From the results of Specific Examples 1 to 3 and Comparative Examples 1 to 3, in order to satisfy simultaneously that the reduction rate of free chlorine is 60% or more and the generation amount of activated carbon fine powder is 2 NTU or less, activated carbon It turns out that it is preferable to make the filling rate of 60-90 volume%.

  Table 1 shows the case of the activated carbon in the case where the water purification cartridge has an opening (water passage hole) only on the peripheral surface and the case where the cartridge lid has an opening in addition to the opening on the peripheral surface. The free residual chlorine reduction rate by the different shaking time when the filling rate is 60% by volume is shown. According to Table 1, free residual chlorine is reduced when the cartridge lid is opened, regardless of the length of the shaking time, whether the cartridge lid is opened or not. The rate is high. This is because not only the peripheral surface of the water purification cartridge but also the opening in other parts of the cartridge complicates the flow of water into and out of the water purification cartridge, increasing the contact area of water with activated carbon and free residual chlorine. Means to adsorb efficiently.

  Table 2 shows that the filling ratio of the granular activated carbon with respect to the water purification cartridge is 60% by volume, the rotation speeds of rotation are 200 rpm and 100 rpm, and each shaking rotation speed is 8 seconds, 20 seconds, 30 seconds, The measurement results are shown for the reduction rate of free chlorine (%) and the amount of fine powder generated (NTU) generated from granular activated carbon when shaking is performed in five shaking times of 60 seconds and 90 seconds. The number of experiments at this time is also 3 times, and the numerical values shown in Table 2 are average values thereof. In these experiments, as can be understood from Table 2, the generation amount of fine powder satisfies the standard for drinking water in all cases, but the reduction rate of free residual chlorine is at two different shaking rotation speeds. The shaking time is over 65% except for 20 seconds. It can also be seen that the free residual chlorine reduction rate increases as each shaking speed shake time increases.
