Entrance 47 sides at cowling panel 54, dispose the gac 56 as adsorbent.This gac 56 is the so-called pressed active carbons that activated carbon fiber are fixed with tackiness agents such as heat bonding resins, and form roughly cylindric, and having the external diameter roughly the same with the entrance 47 side internal diameters of cylindrical body 44, the section shape of this cylindrical body 44 forms circular.The gac 56 formed like this, be housed in cylindrical body 44 by being pressed into from entrance 47 sides, the inner peripheral surface of the reducing diameter part 53a of the periphery of gac 56 pushing cylindrical body 44 and being fixed.That is, the side of gac 56 is the state contacted with the inner peripheral surface of cylindrical body 44.In addition, gac 56 also can form roughly circular cone shape.

Described gac 56 preferably contains fibrous activated carbon.In order to bring into play better water purification performance, described gac 56 preferably contains the fibrous activated carbon of 85～99 quality % with tamped density 0.15～0.3g/ml.

On the other hand, outlet 48 sides at the cowling panel 54 of cylindrical body 44 inside, contain the hollow fiber membrane 57 as filtering membrane.On the corresponding position of formed reducing diameter part 50 on the periphery with cylindrical body 44, hollow fiber membrane 57 cuts off former water side and the water purification side of film by perfusion parts 58 such as urethane resin, epoxy resin, polyolefin resines.And the most close entrance 47 sides in cylindrical body 44, as prefilter, be equipped with non-woven fabrics 55 with the face butt of entrance 47 sides of pressed active carbon.

Adopt above-mentioned example, internal surface in cylindrical body 44 has scarp 53a, thereby can prevent the gac 56 entered from entrance 47 side pressures of cylindrical body 44, due to the inflow of former water to the outlet 48 side shiftings, and owing to keeping the side of gac 56 by cylindrical body 44, so can prevent from damaging because of the shape of the pressed active carbons such as impact.

And, by the shape that prevents gac 56, to damage, the ratio of the tackiness agent for example comprised with in the past pressed active carbon is compared, and the ratio of the tackiness agent that gac 56 comprises is reduced, and can maintain absorption property constant and realize miniaturization.

In addition, because gac 56 is pressed in cylindrical body 44, therefore can prevent from producing gap between gac 56 and cylindrical body 44, can make reliably former water flow through gac 56, can give full play to the absorption property of gac 56.

And, due to interior just passable as long as gac 56 is pressed into to cylindrical body 44, operator's burden in the time of therefore can alleviating assembling.

In addition, by the content by fibrous activated carbon be made as 85～99% scope, density after filling is made as 0.15～0.30g/ml, with the situation that contains the not enough 0.15g/ml of quantity not sufficient 85% and tamped density or be greater than 0.30g/ml of fibrous activated carbon, compare, can bring into play better water purification performance.

Due to using non-woven fabrics 55 as prefilter, therefore can prevent that the larger logistics that is filtered from entering box body inside, and can suppress to flow out to box body is outside from the powdered active carbon that pressed active carbon produces.

And, owing to making the water purifying cartridge miniaturization in the situation that the absorption property of gac 56 is reduced, therefore can realize the miniaturization of water purifier self, therefore, can improve commodity.

In addition, on cowling panel 54, be provided with many arm 54d for flowing through of water carried out to rectification, thereby make to bump against on arm 54d from the current of entrance 47 sides through inside flow direction outlet 48 sides of cylindrical body 44, therefore these current local offset and water is flowed in cylindrical body 44 equably not, result can further improve as the gac 56 of adsorbent with as the utilising efficiency of the hollow fiber membrane 57 of filtering membrane.

In addition, in above-mentioned example, the situation with hooking sheet 16 stationary bodies 3 and water purifying cartridge 4 is illustrated, but also can omits this hooking sheet 16.

And, cartridge body 13a and cylindrical body 44 are formed to situation cylindraceous and be illustrated, but so long as tubular is not limited to cylindric.

The water purifier of this example, comprise described water purifying cartridge 4 and the water purifier main body with pure water inlet 8.

Here, described water purifying cartridge 4 and have the water purifier main body of pure water inlet 8, chimeric on the outer wall of the box body by being located at water purifying cartridge or water purifier main body, screw thread is fixed, the known connection mechanism such as bayonet socket and connecting, but identical with the water purifier of described the first example, be preferably on the one party of the outer wall of box body of described water purifying cartridge and water purifier main body external tapping is set, the opposing party, inner joint is set, this external tapping inserts and is fitted in inner joint, chimeric by described external tapping and described inner joint, form the water passage between described water purifier main body and described water purifying cartridge, and described water purifying cartridge is installed on described water purifier main body.

Next, the water purifying cartridge of the water purifier of the 3rd example of the present invention is described, in the water purifier of this example, for the identical structure of the structure with described the first example, description thereof is omitted.

The water purifying cartridge of this example comprises: the filtering unit 43 that has filter member (gac 56, hollow fiber membrane 57) in cylindrical body 44, accommodate the cartridge body 13a of this filtering unit 43, and be arranged on the inboard of the peristome 40 of this cartridge body, by the lid 13b of described peristome 40 sealings, it is characterized in that, described lid 13b, surface has the bias current inhibition member (rib 61) of the skew that suppresses current within it, and the bias current of described lid 13b suppresses entrance 47 sides that member (rib 61) is configured in described filtering unit 43.

On the inner peripheral surface of the cylindrical body 44 of described filtering unit 43, slightly close entrance 47 sides of formed stage portion 45 on cylindrical body 44 peripherys, be formed with step 53, near the inside of the cylindrical body 44 this step 53, be inserted with cowling panel 54, this cowling panel 54 has near the roughly the same profile of internal diameter entrance 47 sides with step 53, and has a plurality of hole 54a.Hole 54a allows that the water the processing from entrance 47 sides to outlet 48 sides flows through the inside of cylindrical body 44, and has that current to 57 the water from from gac 56 to hollow fiber membrane carry out rectification and the function that prevents the skew of current.And, resinous middle eye strainer is installed on the 54a of hole.

At the inner peripheral surface of the cylindrical body 44 of entrance 47 sides of step 53, with outlet 48 side phase diameter groups large and from entrance 47 to step 53 undergauges and form the reducing diameter part 53a that is the shape that is tapered gradually.Here, step 53 has the function of the block of cowling panel 54, and the movement to outlet 48 directions limits to cowling panel 54.

On the other hand, be housed in the hollow fiber membrane 57 of outlet 48 sides of cowling panel 54, on the corresponding position of formed reducing diameter part 50 on the periphery with cylindrical body 44, by perfusion parts 58 such as urethane resin, epoxy resin, polyolefin resines, cut off former water side and the water purification side of film.And, in the most close entrance 47 sides of cylindrical body 44, as prefilter, roughly discoid non-woven fabrics 55 is installed.

Lid 13b has and forms roughly discoid main board portion 60, and this main board portion 60 forms section to the outside curve of water purifying cartridge 4 and is roughly arc.And, on the outer peripheral edges of main board portion 60, be formed with to the protuberance 60a of the interior side-prominent ring-type of cartridge body 13a.

On the internal surface of main board portion 60, the mobile skew that is provided with the former water that cartridge body 13a inside is flowed into suppresses the bias current inhibition member of use.Bias current suppresses member can be according to the shape of water purifying cartridge, from the structure such as rib, groove and the projection of the inner surface side that is located at main board portion 60 and their combination, suitably selecting.

With reference to Figure 10 and Figure 11, the example that this bias current suppresses member is specifically described.As shown in Figure 10 and Figure 11, at the internal surface of the main board portion 60 of lid 13b, as bias current, suppress member and be formed with a plurality of ribs 61.These ribs 61 are respectively by from main board portion 60De center, forming radial radiation direction rib 62, and the end, the circumferential rib 63 that namely circumferentially form along the outer rim of main board portion 60 that are configured in this radiation direction rib 62 form.

In addition, on the middle position between each circumferential rib 63 on each circumferential rib 63 extended lines, be provided with to the outstanding projection 64 of the inner surface side of main board portion 60.And radiation direction rib 62 is tilted the shape of ground incised notch for the bight of its center side.According to the shape of water purifying cartridge, also can omit projection 64 in addition.

The inboard of the peristome 40 of lid 13b built-in box phosphor bodies 13a, the periphery of lid 13b is fixed in the inner peripheral surface of peristome 40 by above-mentioned ultrasonic wave coating or embedding etc.At lid 13b, be fixed under the state of cartridge body 13a, become the state (with reference to figure 6) of the cylindrical body 44 inlet side end faces of the filtering unit 43 that the formed circumferential rib of lid 13b internal surface 63 pushing cartridge body 13a accommodate.Thus, radiation direction rib 62 and circumferential rib 63 in entrance 47 sides of filtering unit 43 in abutting connection with configuration.Therefore, as bias current, suppress member and preferably adopt the structure that contains above-mentioned rib.Radiate in addition number or the angle of direction rib 62 and circumferential rib 63, as long as it is just passable to carry out suitable setting, consider but suppress this point from bias current, preferably 2 adjacent radiation direction ribs 62 all are configured to have angle about equally.

Here, on Figure 10 and lid 13b shown in Figure 11, radiation direction rib 62 is disposed at respectively 4 positions with the interval of about 90 °, near main board portion 60De center until near outer peripheral edges.On the other hand, circumferential rib 63 is centered by the end of the radial outside of radiation direction rib 62, and the scope that spreads all over about 45 ° forms arc, separately and the interval between adjacent circumferential rib 63 be set to 45 ° of left and right.In addition, the interval between adjacent circumferential rib 63 is not limited to 45 °, and 40 °～50 ° left and right also can obtain identical effect.

That is,, after the former water that flows into water purifiers 1 from water channel water tap 2 enters the inside of water purifier 1 from former water receiving port 5, flow into the operational stage of respective operations bar 9 and the former water that is not switched valve 23 obturations imports path 27 or former water passage 28.When former water flows into former water passage 28, intactly to shower outlet 7 guiding and as the former water of shape spray, flowed out to the outside of water purifier 1 from shower outlet 7.

On the other hand, when former water flowed into former water importing path 27, former water imports path 27 by forming former water inner joint 12b and external tapping 14b flowed in the box body 13 of water purifying cartridge 4.Next, as shown in Figure 6, former water bumps against on the internal surface of lid 13b after towards entrance 47 effluents of filtering unit 43, crossing the path T1 between the outside wall surface of the inwall 41 that is formed on cartridge body 13a and filtering unit 43.

This former water is through the end face of the protuberance 60a by lid 13b periphery, circumferential rib 63, filtering unit 43 and path 65 that main board portion 60 zonings form and around entering all-round to lid 13b.Next, should between circumferential rib 63 and projection 64, enter respectively lid 13bDe center (using the represented direction of arrow of two dot chain line Figure 10) around the former water entered, then, collide on radiation direction rib 62.To lid 13bDe center, enter and collide the former water on radiation direction rib 62,4 regional R that surround from the radiation direction rib 62 by adjacent and circumferential rib 63 invade cylindrical body 44 inside through the non-woven fabrics 55 of entrance 47 sides of filtering unit 43 respectively.In addition, when Dang Yuanshui flows through path 65, also by non-woven fabrics 55, slightly invade in cylindrical body 44.

Invade the former water of the inside of cylindrical body 44, after by gac 56 and hollow fiber membrane 57, being adsorbed filtration successively, go out from outlet 48 effluents of filtering unit 43 as water purification.From the water purification that this filtering unit 43 flows out, the outlet formed path T2 of 48 side and the water purification path 26 of the O shape circle 52 of process box body 13 inside flow into main bodys 3, flow down from pure water inlet 8.

Adopt above-mentioned example, by lid 13b being mounted and fixed on to the inboard of the peristome 40 of box body 13, can do the size of the peristome of box body 13 40 peripheries less, therefore can realize the miniaturization of water purifying cartridge 4.

And, the skew that imports to the current that the former water in box body 13 produce by 61 pairs, rib suppresses, then make this former water flow into cylindrical body 44 inside from the entrance 47 of filtering unit 43, therefore can the skew of the current that flow through cylindrical body 44 inside be suppressed, result, can alleviate the filter member, the especially burden of gac 56 that are housed in cylindrical body 44.

In addition, by the circumferential rib 63 that forms rib 61, can entrance 47 side end faces of cylindrical body 44 be pushed, therefore with the situation of the projection that pushing filtering unit 43 is set in addition, compare, can set the gauge of lid 13b smaller, as a result, can further realize the miniaturization of water purifying cartridge 4.

Main board portion 60 is crooked and form laterally, thereby collides lid 13b when upper when former water, can collide angle initialization for more slow, so can realize the raising of withstand voltage properties, and result, can prevent from making in order to ensure intensity lid 13b maximization.

And, the former water that can make to encounter on the main board portion 60 of lid 13b collides with the radiation direction rib 62 that is radial setting and at least one rib 61 in the interrupted circumferential rib 63 arranged of the outer rim of lid 13b, can change the direction of current thus, therefore can be with the skew of simple STRUCTURE DEPRESSION current.

In addition, radiation direction rib 62 and circumferential rib 63 are set on the main board portion 60 of lid 13b, thereby can improve the intensity of lid 13b, therefore can when guaranteeing the intensity that main board portion 60 is enough, make its thin-walled more, further realize the miniaturization of water purifying cartridge 4.

In the water purifier of this example, external tapping 14a, 14b, 14c and inner joint 12a, the 12b, the 12c that in order to make main body 3 and water purifying cartridge 4 combinations, arrange, form respectively water purification path 26, former water importing path 27, therefore with the situation that in the past water purifier arranges like that respectively combination member unit and path, compare, can omit be used to configuring the space of combination member, main body 3 and the water purifying cartridge 4 of water purifier are configured near each otherly, as a result, can dwindle the size of water purifier 1 and further realize the miniaturization of water purifier.

In addition, in above-mentioned example, to by ultrasonic wave coating etc., the situation that lid 13b is fixed in cartridge body 13a being illustrated, the method that lid 13b is mounted on to cartridge body 13a can adopt the whole bag of tricks, for example, also can form outside screw in the periphery of the protuberance of lid 13b, and near the interior week formation internal thread the peristome 40 of cartridge body 13a, the peristome 40 of lid 13b and cartridge body 13a is screwed togather and lid 13b is fixed on peristome 40.

And, in example, be illustrated as example take situation that radiation direction rib 62 and circumferential rib 63 are set, as long as but that any in radiation direction rib 62 or circumferential rib 63 is set is just passable.When radiation direction rib 62 only was set, entrance 47 sides of radiating direction rib 62 pushing filtering units 43 as long as make were just passable.

Next, the water purifying cartridge of the water purifier of the 4th example of the present invention is described, in the water purifier of this example, for the identical structure of the structure with described the first example, omit part explanation.

The water purifying cartridge 4 of this example, in box body 13, contain and be shaped to the pressed active carbon 158 that two ends have the tubular of peristome, it consists of gac and tackiness agent, between described gac 158 and described inboard wall of cartridge 41, be formed with water passage T1, it is characterized in that, at least the flap (non-woven fabrics 160) that the face contacted with described water passage T1 of the side of described pressed active carbon 158 is formed by fiber covers, the two state contacted of inwall (internal surface 163) with at least one opening end with described pressed active carbon 158 and described box body is provided with elastomerics (bolster 161).

Next, with reference to Figure 12～13, water purifying cartridge 4 is described.

Water purifying cartridge 4, have box body 13, and this box body 13 comprises: the cartridge body 13a that the round-ended cylinder shape is roughly arranged that is with above-mentioned external tapping 14a, 14b, 14c; And the lid 13b that is arranged on peristome 40 inboards of cartridge body 13a, this lid 13b is fixed in cartridge body 13a by ultrasonic wave coating etc.On the inwall 41 of cartridge body 13a, in the scope between described external tapping 14a and external tapping 14c, the diapire 13c of the cartridge body 13a reducing diameter part 42 of undergauge gradually radially in being formed with.In this box body 13, contain filtering unit 43.

Filtering unit 43 consists of the 43a of membrane module section and adsorption section 43b.The 43a of membrane module section has roughly cylindrical body 44 cylindraceous, at the described former water of the periphery of this cylindrical body 44, imports on the position on the extended line of path 27, is formed with stage portion 45.Here, by configuration stage portion 45 on the extended line of the former water importing path 27 at external tapping 14b, the box body 13 interior former water that make to import path 27 inflow water purifying cartridges 4 by former water bump against on stage portion 45, turn to adsorption section 43b side (direction in Figure 12 shown in arrow).

Cylindrical body 44, in outlet 46 sides of stage portion 45, be formed with than the large large-diameter portion 148 of the entrance of cylindrical body 44 47 side diameters.On the periphery of outlet 46 sides of this large-diameter portion 148, be formed with the groove 149 of ring-type, O shape circle 150 is installed on this groove 149.And on cylindrical body 44, outlet 46 sides in the position that O shape circle 150 is installed, be formed with gradually to the reducing diameter part 151 that exports 46 side undergauges.

On the other hand, in the inside of cylindrical body 44, contain hollow fiber membrane 152.This hollow fiber membrane 152, on the position corresponding with reducing diameter part 151, cut off former water side and the water purification side of film by perfusion parts 153 such as urethane resin, epoxy resin, polyolefin resines.

At the entrance 47 of cylindrical body 44, the basal component 154 that forms adsorption section 43b is installed.This basal component 154 is by forming roughly discoid base portion 155 and forming to the side-prominent axial region 156 of lid 13b from the centre portions of this base portion 155.Base portion 155, its external diameter is arranged on the inboard of entrance 47.On the other hand, axial region 156, the general hollow that forms end-enclosed is cylindric, on its perisporium, is formed with a plurality of holes 157 that the outside that makes axial region 156 and internal space are communicated with.The internal space of axial region 156, be communicated with the internal space of the 43a of membrane module section in base portion 155 sides.

In above-mentioned basal component 154, it is gac 158 that pressed active carbon is installed.Gac 158 forms by powdered active carbon and by the tackiness agent of heat bonding resin formation, by so-called wet type, attracts the method for forming such as the method for forming integrally formed.In gac 158, the median size of contained Powdered Activated Carbon preferably is set as 50～150 μ m, and the content of tackiness agent preferably is set as 0.1～2 quality %.In addition, the forming method of gac 158 is not limited to above-mentioned wet type and attracts the method for forming, can be also by the pressed active carbon of the acquisitions such as dry formed method.

Gac 158, form therein and have the roughly cylindric of communicating pores 159 on axle, the internal diameter of this communicating pores 159 be set to the external diameter of axial region 156 about equally.The axial region 156 of basement member 154 in the communicating pores 159 of gac 158, thus gac 158 is arranged on basal component 154.

In addition, it must be cylinder that the shape of gac 158 does not need, so long as tubular just can reach effect of the present invention, such as can be also bottom surface be the regular polygons such as regular hexagon or polygon-octagonal the cylinder.

Gac 158 at least with periphery that described water passage T1 contacts on, be wound with for example, as the flap of specific thickness (0.5～2.0mm left and right) non-woven fabrics 160, the terminal part of its coiling direction is fixed by bonding grade.It is slightly wide that this non-woven fabrics 160 forms the axial length dimension of specific activity charcoal 158, the remainder of the upper limb produced while being wound on this non-woven fabrics 160 on gac 158 is to an end face lateral buckling of gac 158, and the remainder of lower edge is to the other end lateral buckling of gac 158.

Here, by non-woven fabrics 160, setting above-mentioned remainder, for example, when gac 158 swellings and axial dimension extend when moist, can prevent that gac 158 is to path T1(aftermentioned) directly expose.Form the fiber of non-woven fabrics 160, can use animal hair, cellulose acetate of polyolefine, polyester, glass, nylon, vinylon, propylene, viscose fiber, copper ammonia fibre, cotton, wool etc. etc., in these fibers, especially preferably use lower polyolefine, polyester, the glass of water-intake rate (public affairs are determined moisture rate) of the swelling that can suppress non-woven fabrics 160.And flap is not limited to non-woven fabrics 160, so long as that have water flowing and have a suitable mesh and for the shape that keeps pressed active carbon, to have a flap of enough intensity just passable, such as using felt, cloth etc.Wherein, due to non-woven fabrics or felt, the mesh of its thickness direction is random, if therefore gac is peeled off, also is difficult to occur descend because mesh stops up the flow caused, and in this, can use more well than cloth.And, in non-woven fabrics 160, felt, cloth, also can add tackiness agent, auxiliary line, other resin combination be used to keeping suitable shape.

Between the internal surface 163 of the lid 13b of the end face of above-mentioned gac 158 and box body 13, discoid bolster 161(elastomerics is installed).This bolster 161 consists of foaies such as having elastic so-called polyethylene, urethane foam.By this bolster 161, gac 158 is leaned on to the 43a of membrane module section thruster, in addition, the caused deflection of the swelling to lid 13b side of assimilating activity charcoal 158.In addition, bolster 161 is not limited to foam, so long as elastomerics such as also using elastomeric formed body consisted of isoprene, propylene etc. etc., and is not limited to discoid.

Next, the step that above-mentioned filtering unit 43 is accommodated in box body 13 is described.

At first, will on gac 158 cylindraceous, be arranged in advance on basal component 154 by the object of coiling non-woven fabrics 160.Then, from the 43a of the membrane module section side of filtering unit 43, at first to cartridge body 13a, insert.Next, making to be arranged on O shape circle 150 on cylindrical body 44 encounters on the reducing diameter part 42 of internal surface of cartridge body 13a, from this state, further on direction of insertion, filtering unit 43 is pushed, O shape circle 150 is pushed gradually, when O shape circle 150 arrived near the external tapping 14a of reducing diameter parts 42, filtering unit 43 no longer moved to direction of insertion.

After filtration unit 43 is inserted into cartridge body 13a, bolster 161 is placed on the open end-face of gac 158, lid 13b is arranged on peristome 40.That is, bolster 161 is clipped between the internal surface 163 of the end face of gac 158 of relative configuration and lid 13b.Like this, by the internal surface 163 pushing bolsters 161 of lid 13b, from lid 13b thruster, press gac 158 by this bolster 161.

Inside at box body 13, internal space is separated by above-mentioned O shape circle 150, in entrance 47 sides of O shape circle 150, between the inner peripheral surface of the periphery of gac 158 and cartridge body 13a and the path T1 that is formed with former current direction entrance 47 sides between the inwall 41 of the periphery of cylindrical body 44 and cartridge body 13a.Similarly, in outlet 46 sides of O shape circle 150, periphery, the inner peripheral surface of cartridge body 13a, the box portion bottom wall 13c zoning of the outlet side end face by filtering unit 43, the reducing diameter part 151 of cylindrical body 44 form the path T2 that water purification flows through.

Here, above-mentioned external tapping 14b is configured on the cartridge body 13a periphery wall of gac 158 sides of the O shape circle 150 of installing on cylindrical body 44, and above-mentioned external tapping 14a is configured on the cartridge body 13a periphery wall of outlet 46 sides of O shape circle 150.

That is, from above-mentioned water channel water tap 2, flow into the former water of water purifiers 1, from former water receiving port 5, enter the inside of water purifier 1, flow into the operational stage of respective operations bar 9 and the former water that is not switched valve 23 obturations imports path 27 or former water passage 28.When former water flows into former water passage 28, intactly to shower outlet 7 guiding and as the former water of shape spray, flowed out to the outside of water purifier 1 from shower outlet 7.

On the other hand, when former water flowed into former water importing path 27, former water imports path 27 by forming former water inner joint 12b and external tapping 14b flowed in the box body 13 of water purifying cartridge 4.Next, as shown in figure 12, former water is crossed path T1 to gac 158 effluents.

This former water, around the periphery integral body that enters gac 158, invade in gac 158 by non-woven fabrics 160.Invade the former water in gac 158, flow to the communicating pores 159 of gac 158 and the hole 157 by the axial region 156 of basal component 154 flows into the 43a of membrane module section as the water after absorption.Water after the absorption of the inflow 43a of membrane module section goes out from outlet 46 effluents of filtering unit 43 as water purification after by hollow fiber membrane 152, being filtered.Should by path T2 and water purification path 26, flow in main bodys 3 from the water purification of filtering unit 43 outflows, flow down from pure water inlet 8.

Adopt above-mentioned the 4th example, binder content by the gac 158 that will consist of powdered active carbon and tackiness agent is made as 0.1-2 quality %, thereby compare with pressed active carbon in the past, can reduce the content of tackiness agent, therefore can fully guarantee the derived methane absorption property of pressed active carbon and realize miniaturization.

And, by with the non-woven fabrics 160 coverage rates side to the gac 158 of path T1, can prevent that binder content from reducing and the shape that becomes fragile gac 158 is damaged, the processing ease in the time of can guaranteeing to assemble.

In addition, the distortion that while preventing by water flowing by non-woven fabrics 160, gac 158 causes to swelling of path T1 direction etc., and be provided with in the lid 13b of gac 158 side the part do not covered by non-woven fabrics 160, thereby allow to the caused distortion such as swelling of lid 13b direction, and can absorb deflection by bolster 161, therefore can prevent to non-woven fabrics 160, applying excessive burden due to the distortion of gac 158, and can alleviate the burden applied to lid 13b and cartridge body 13a.

By bolster 161 is set, can press gac 158 from lid 13b thruster, prevent the movement to the plug direction in box body 13, therefore can prevent that gac 158 from contacting with box body etc. and cause that shape damages, result can suppress to concentrate on due to the caused water flowing of shape damage of gac 158 problem of the privileged site of gac 158.

And, when the median size by powdered active carbon is set as while being less than 50 μ m, the tamped density of gac 158 is too high, when being set as while being greater than 150 μ m, the trend that exists absorption property to reduce, but, by being set as 50 μ m～150 μ m, can fully guarantee filtering traffic and guarantee good absorption property.

In addition, can not make removal (absorption) performance of derived methane reduce and can make gac 158 miniaturizations, therefore can realize the miniaturization of water purifier 1.
