Description

本発明は、携帯型浄水器に関する。 The present invention relates to a portable water purifier.

携帯型浄水器は、容器とそれに取り付けられた浄水カートリッジとを有しており、水道水などの水を容器に入れ、その浄化前の水を浄水カートリッジにより浄化（浄水）するものである。携帯型浄水器の中には、加圧手段を有するものが有る。加圧手段を有する携帯型浄水器では、柔軟な加圧手段を把持して圧縮すると、浄化前の水は浄水カートリッジの浄化材（ろ材）を通過し、そのときその水に含まれる塩素や有機物などの不純物が捕捉されることによって浄水となる。 A portable water purifier has a container and a water purification cartridge attached to the container. Water such as tap water is put into the container, and the water before purification is purified (purified) by the water purification cartridge. Some portable water purifiers have a pressurizing means. In a portable water purifier having a pressurizing means, when the flexible pressurizing means is grasped and compressed, the water before purification passes through the purifying material (filter medium) of the water purification cartridge, and chlorine and organic substances contained in the water at that time. Water is purified by trapping impurities such as.

例えば、特許文献１に開示される携帯型浄水器は、浄化前の水を貯留する筒状の容器本体が加圧手段となっており、使用時に逆さにして又は逆さ近くに傾けてこの容器本体を圧縮すると、中の空気及び浄化前の水が加圧され、加圧された水は、浄水カートリッジのろ材の外側から内側に通過し、ろ材の内側の一方側に設けた浄水流出部（ａｄａｐｔｅｒ）から外部（口内など）に浄水として流出する。このように容器本体が加圧手段となっている携帯型浄水器は、コンパクトな構造であり、屋外などでの使用に好適である。 For example, in the portable water purifier disclosed in Patent Document 1, a tubular container body for storing water before purification is used as a pressurizing means, and the container body is turned upside down or tilted near upside down during use. When the water is compressed, the air inside and the water before purification are pressurized, and the pressurized water passes from the outside to the inside of the filter medium of the water purification cartridge, and the purified water outflow portion (adapter) provided on one side inside the filter medium is provided. ) Outflows to the outside (in the mouth, etc.) as purified water. As described above, the portable water purifier in which the container body serves as a pressurizing means has a compact structure and is suitable for outdoor use.

また、特許文献２に開示される携帯型浄水器は、特許文献１と同様に容器本体が加圧手段となっており、浄水流出部に浄水カートリッジを装着することで外部に浄水が流出するようにできる。更には、この携帯型浄水器は、浄水カートリッジを一旦取り外して水道水を容器本体に注入し、浄水流出部に浄水カートリッジを逆向きに装着し、それから逆さにして又は逆さ近くに傾けて容器本体を圧縮すると、加圧された水道水が浄水流出部、そして、浄水カートリッジのろ材の内側から外側に通過する。そうすることによって、浄水カートリッジを洗浄してそれに補足され蓄積された不純物を排出するようにできる。 Further, in the portable water purifier disclosed in Patent Document 2, the container body serves as a pressurizing means as in Patent Document 1, and by attaching a water purification cartridge to the water purification outflow portion, purified water flows out to the outside. Can be done. Furthermore, in this portable water purifier, the water purification cartridge is once removed, tap water is injected into the container body, the water purification cartridge is mounted in the reverse direction on the water purification outflow part, and then the container body is turned upside down or tilted near the upside down. When the tap water is compressed, the pressurized tap water passes from the inside to the outside of the water purification outflow part and the filter medium of the water purification cartridge. By doing so, the water purification cartridge can be cleaned to expel the impurities that are trapped and accumulated in it.

以下、本発明を実施するための形態を説明する。本発明の実施形態に係る携帯型浄水器１は、図１に示すように、容器本体２と内蓋体３と外蓋体４と浄水カートリッジ５と空気逆止弁６とを備えている。 Hereinafter, modes for carrying out the present invention will be described. As shown in FIG. 1, the portable water purifier 1 according to the embodiment of the present invention includes a container body 2, an inner lid 3, an outer lid 4, a water purification cartridge 5, and an air check valve 6.

容器本体２は、図１及び図２に示すように、柔軟なものであって、開口部と底部を有する筒状のものである。詳しくは、柔軟なものとは、容器本体２を把持して力を入れると圧縮変形し、力を緩めると形状が復元するようなものである。それにより、容器本体２は、加圧手段となる。容器本体２の材質は、特に限定されるものではないが、例えば、柔軟なポリエチレンなどを用いることができる。容器本体２は、水道水などの浄化前の水を入れるように、一方側（図１及び図２においては上側）に開口部を有し、他方側に底部を有している。容器本体２の底部は、携帯型浄水器１全体の底部となる。携帯型浄水器１は、図１に示すように、その底部を下にして直立することができる。 As shown in FIGS. 1 and 2, the container body 2 is flexible and has a tubular shape having an opening and a bottom. More specifically, the flexible one is such that when the container body 2 is gripped and a force is applied, the container body 2 is compressed and deformed, and when the force is relaxed, the shape is restored. As a result, the container body 2 becomes a pressurizing means. The material of the container body 2 is not particularly limited, but for example, flexible polyethylene or the like can be used. The container body 2 has an opening on one side (upper side in FIGS. 1 and 2) and a bottom portion on the other side so as to contain unpurified water such as tap water. The bottom of the container body 2 is the bottom of the entire portable water purifier 1. As shown in FIG. 1, the portable water purifier 1 can stand upright with its bottom facing down.

容器本体２は、その一方側（開口部側）において、後に詳述する内蓋体３が着脱自在に装着される。そのため、容器本体２は、一方側の端部近傍の外側部に雄ねじ２ａが形成されている。 On one side (opening side) of the container body 2, the inner lid 3 described in detail later is detachably attached. Therefore, the container body 2 has a male screw 2a formed on the outer side near the end on one side.

容器本体２は、側部に２個以上の環状の窪み部２ｂ、２ｂ’が形成されているのが好ましい。そうすると、容器本体２は、窪み部２ｂ、２ｂ’から底部の間の部分を把持して圧縮したときに、窪み部２ｂ、２ｂ’から一方側の端までの間の部分及び内蓋体３の装着部近傍が変形し難くなる。それにより、内蓋体３の装着部での漏水等の不具合の可能性をなくすようにすることができる。 The container body 2 preferably has two or more annular recessed portions 2b and 2b'formed on the side portions. Then, when the container body 2 grips and compresses the portion between the recessed portions 2b and 2b'and the bottom portion, the portion between the recessed portions 2b and 2b'and one end and the inner lid body 3 The vicinity of the mounting part is less likely to be deformed. As a result, it is possible to eliminate the possibility of problems such as water leakage at the mounting portion of the inner lid body 3.

内蓋体３は、上記のように、容器本体２の一方側（開口部側）に着脱自在に装着され得るものである。内蓋体３は、図１に示すように、他方側（図１においては下側）の端部近傍の内側部に雌ねじ３ａが形成されており、その雌ねじ３ａと容器本体２の雄ねじ２ａの螺着により、内蓋体３は容器本体２の一方側の端部近傍の外側部を囲むように装着される。なお、内蓋体３（及び外蓋体４）は、容器本体２のように柔軟である必要はなく、通常は、硬い（変形し難い）ものである。内蓋体３（及び外蓋体４）の材質は、特に限定されるものではないが、例えば、ポリプロピレンなどを用いることができる。 As described above, the inner lid body 3 can be detachably attached to one side (opening side) of the container body 2. As shown in FIG. 1, the inner lid 3 has a female screw 3a formed on the inner side near the end on the other side (lower side in FIG. 1), and the female screw 3a and the male screw 2a of the container body 2 are formed. By screwing, the inner lid 3 is attached so as to surround the outer portion near the end on one side of the container body 2. The inner lid 3 (and the outer lid 4) does not need to be flexible like the container body 2, and is usually hard (hard to be deformed). The material of the inner lid 3 (and the outer lid 4) is not particularly limited, but polypropylene or the like can be used, for example.

また、内蓋体３は、図１及び図３（ａ）、（ｂ）に示すように、浄水流出部（第１浄水流出部）３ｂを有する。浄水流出部３ｂは、外方（図１及び図３（ｂ）においては上方）に突出している。また、浄水流出部３ｂは、端面の中央部に設けられている。第１浄水流出部３ｂは、円筒形又は角筒形とすることができる。 Further, the inner lid 3 has a purified water outflow portion (first purified water outflow portion) 3b as shown in FIGS. 1 and 3 (a) and 3 (b). The purified water outflow portion 3b projects outward (upward in FIGS. 1 and 3 (b)). Further, the purified water outflow portion 3b is provided in the central portion of the end face. The first purified water outflow portion 3b may have a cylindrical shape or a square tubular shape.

第１浄水流出部３ｂの内部には、軸方向に貫通孔（第１貫通孔）３ｂａが設けられている（図３（ａ）参照)。第１貫通孔３ｂａは、内蓋体３の内側から（図１及び図３（ｂ）においては内蓋体３の下側から）浄水カートリッジ５の後述する第２浄水流出部５２ａが装着され得る構造になっている。例えば、第１浄水流出部３ｂの第１貫通孔３ｂａには、浄水カートリッジ５の第２浄水流出部５２ａの装着のために、一対の支持片３ｂｂが対向して内壁面に設けられるようにし、第２浄水流出部５２ａには、後に詳述する一対の被支持片５２ａａが外壁面に設けられるようにすることができる。支持片３ｂｂは、通常は薄板状である。 Inside the first purified water outflow portion 3b, a through hole (first through hole) 3ba is provided in the axial direction (see FIG. 3A). The first through hole 3ba may be fitted with a second water purification outflow portion 52a, which will be described later, of the water purification cartridge 5 from the inside of the inner lid 3 (from the lower side of the inner lid 3 in FIGS. 1 and 3B). It has a structure. For example, a pair of support pieces 3bb are provided on the inner wall surface of the first water purification outflow portion 3b so as to face each other in the first through hole 3ba for mounting the second water purification outflow portion 52a of the water purification cartridge 5. The second purified water outflow portion 52a may be provided with a pair of supported pieces 52aa, which will be described in detail later, on the outer wall surface. The support piece 3bb is usually in the shape of a thin plate.

外蓋体４は、螺着などにより、着脱自在に内蓋体３に装着され得るものである。外蓋体４は、内側に突起４ａを設け、内蓋体３に装着されたときに第１浄水流出部３ｂの第１貫通孔３ｂａに栓がされるようにすることができる。また、外蓋体４は、図１に示すように、第１浄水流出部３ｂより周辺の部分において装着されるようにすると、取りはずしたときコップとして使用することも可能である。また、コップとしての使用は難しいが、外蓋体４は、第１浄水流出部３ｂの外周面に装着されるようにすることも可能である。 The outer lid body 4 can be detachably attached to the inner lid body 3 by screwing or the like. The outer lid body 4 may be provided with a protrusion 4a on the inside so that when the outer lid body 4 is attached to the inner lid body 3, the first through hole 3ba of the first purified water outflow portion 3b is plugged. Further, as shown in FIG. 1, if the outer lid body 4 is attached in a portion around the first purified water outflow portion 3b, it can be used as a cup when it is removed. Further, although it is difficult to use as a cup, the outer lid body 4 can be mounted on the outer peripheral surface of the first purified water outflow portion 3b.

浄水カートリッジ５は、図５（ａ）、（ｂ）、図６（ａ）、（ｂ）、図７（ａ）、（ｂ）、図８（ａ）、（ｂ）、に示すように、ろ材５１とろ材収容体５２を有する。 The water purification cartridge 5 is provided as shown in FIGS. 5 (a), 5 (b), 6 (a), (b), 7 (a), (b), 8 (a), (b). It has a filter medium 51 and a filter medium accommodating body 52.

ろ材５１は、軸方向に中空部５１ａが設けられている。ろ材５１は、円筒状のものを用いることができる。ろ材５１は、特に材料は限定されないが、活性炭成形フィルター、中空糸膜、平膜、セラミック膜、積層フィルター、糸巻フィルター、金属フィルターなどが可能である。また、ろ材５１は、保護等の目的で、一般的に、薄い不織布等により外周面及び内周面が覆われている。 The filter medium 51 is provided with a hollow portion 51a in the axial direction. As the filter medium 51, a cylindrical one can be used. The material of the filter medium 51 is not particularly limited, but an activated carbon molding filter, a hollow fiber membrane, a flat film, a ceramic film, a laminated filter, a thread winding filter, a metal filter and the like can be used. Further, the outer peripheral surface and the inner peripheral surface of the filter medium 51 are generally covered with a thin non-woven fabric or the like for the purpose of protection or the like.

ろ材収容体５２は、ろ材５１を収容する筒状のものである。ろ材収容体５２は、円筒状のものを用いることができる。なお、ろ材収容体５２は、図示は省略するが、一般的に、ろ材５１を内部に配置した後、２個の部材が合体して出来上がっている。また、ろ材５１は、一般的に、両端面（図７（ａ）、（ｂ）においては上側及び下側の面）がろ材収容体５２に接着される。 The filter medium accommodating body 52 has a tubular shape for accommodating the filter medium 51. As the filter medium accommodating body 52, a cylindrical one can be used. Although not shown, the filter media accommodating body 52 is generally completed by arranging the filter media 51 inside and then combining two members. Further, in the filter medium 51, both end surfaces (upper and lower surfaces in FIGS. 7A and 7B) are generally adhered to the filter medium accommodating body 52.

ろ材収容体５２は、浄水流出部（第２浄水流出部）５２ａを有する。第２浄水流出部５２ａは、ろ材収容体５２の一端面（図５（ｂ）等）においては上側の面）から外方（図５（ｂ）等においては上方）に突出している。第２浄水流出部５２ａは、ろ材収容体５２の一端面の中央部に設けられている。第２浄水流出部５２ａの内部には、その軸方向に、ろ材５１の中空部５１ａに連通する貫通孔（第２貫通孔）５２ｂが形成されている。 The filter medium accommodating body 52 has a purified water outflow portion (second purified water outflow portion) 52a. The second purified water outflow portion 52a projects outward (upward in FIG. 5B, etc.) from one end surface (upper surface in FIG. 5B, etc.) of the filter medium accommodating body 52. The second purified water outflow portion 52a is provided in the central portion of one end surface of the filter medium accommodating body 52. Inside the second purified water outflow portion 52a, a through hole (second through hole) 52b communicating with the hollow portion 51a of the filter medium 51 is formed in the axial direction thereof.

第２浄水流出部５２ａは、上記のように、内蓋体３の内側から第１浄水流出部３ｂの第１貫通孔３ｂａに装着できる構造になっている。例えば、上記のように、第１浄水流出部３ｂの第１貫通孔３ｂａには、一対の支持片３ｂｂが対向して内壁面に設けられるようにし、第２浄水流出部５２ａには、一対の被支持片５２ａａが外壁面に設けられるようにすることができる。一対の被支持片５２ａａが一対の支持片３ｂｂに重なり合うことにより、第２浄水流出部５２ａが第１浄水流出部３ｂの第１貫通孔３ｂａに装着される。詳細には、装着のとき、一対の被支持片５２ａａは、内蓋体３の内側から外側に向かって移動させられて一対の支持片３ｂｂの間を通過し、それから略９０度（平面視で略９０度）回動させられて一対の支持片３ｂｂの外側（図１においては、上側）で重なり合う。また、一対の被支持片５２ａａは、回って重なり易くするように回る側の端部はテーパが形成され、また、回り過ぎないようにその反対側の端部はストッパ５２ａｂが設けられている。また、第２浄水流出部５２ａは、その外壁面にＯリング５２ａｃを設けて、後述するように携帯型浄水器１を逆さにして又は逆さ近くに傾けて容器本体２を圧縮したときに第１貫通孔３ｂａの内壁面との隙間で漏水しないようにしてある。 As described above, the second purified water outflow portion 52a has a structure that can be attached to the first through hole 3ba of the first purified water outflow portion 3b from the inside of the inner lid body 3. For example, as described above, the first through hole 3ba of the first purified water outflow portion 3b is provided with a pair of support pieces 3bb facing each other on the inner wall surface, and the second purified water outflow portion 52a is provided with a pair of support pieces 3bb. The supported piece 52aa can be provided on the outer wall surface. By overlapping the pair of supported pieces 52aa with the pair of supporting pieces 3bb, the second purified water outflow portion 52a is attached to the first through hole 3ba of the first purified water outflow portion 3b. Specifically, when mounted, the pair of supported pieces 52aa are moved from the inside to the outside of the inner lid 3 to pass between the pair of support pieces 3bb and then approximately 90 degrees (in plan view). It is rotated (approximately 90 degrees) and overlaps on the outside (upper side in FIG. 1) of the pair of support pieces 3bb. Further, the pair of supported pieces 52aa are provided with a taper at the end on the rotating side so as to easily rotate and overlap, and a stopper 52ab is provided at the end on the opposite side so as not to rotate too much. Further, the second water purification outflow portion 52a is provided with an O-ring 52ac on the outer wall surface thereof, and when the portable water purifier 1 is turned upside down or tilted near the upside down to compress the container body 2, as will be described later, the first Water leakage is prevented in the gap between the through hole 3ba and the inner wall surface.

ろ材収容体５２は、内壁面にスペーサ５２ｃ（図７（ｂ）参照）を有して、それにより、ろ材５１（詳細には、その外側面）との間に内部流水路５２ｄを形成する。 The filter medium accommodating body 52 has a spacer 52c (see FIG. 7B) on the inner wall surface, thereby forming an internal flow channel 52d with the filter medium 51 (specifically, the outer surface thereof).

ろ材収容体５２は、その周面に、浄化前の水が流入する細長い浄化前水流入孔５２ｅを有する。浄化前水流入孔５２ｅは、周方向に形成されている。浄化前水流入孔５２ｅは、内部流水路５２ｄに連通する。また、浄化前水流入孔５２ｅは、第２浄水流出部５２ａが設けられたろ材収容体５２の一端面の近傍に、偏在して設けられている。浄化前水流入孔５２ｅは、例えば、少なくともろ材収容体５２の高さの半分（更に、好ましくは１／３）以下の部分に設けられている。また、浄化前水流入孔５２ｅは、例えば、図５（ｂ）等に示すように一周上にのみ複数個設けられている（つまり、複数個が一周のみを形成している）ようにしたり二周上に複数個設けられているようにしたりできる。場合によっては、三以上の周上に複数個設けられるようにすることも可能である。 The filter medium accommodating body 52 has an elongated pre-purification water inflow hole 52e on its peripheral surface into which pre-purification water flows. The pre-purification water inflow hole 52e is formed in the circumferential direction. The pre-purification water inflow hole 52e communicates with the internal flow channel 52d. Further, the pre-purification water inflow holes 52e are unevenly distributed in the vicinity of one end surface of the filter medium accommodating body 52 in which the second purified water outflow portion 52a is provided. The pre-purification water inflow hole 52e is provided, for example, in a portion of at least half (more preferably 1/3) or less of the height of the filter medium accommodating body 52. Further, for example, as shown in FIG. 5B, a plurality of pre-purification water inflow holes 52e are provided only on one circumference (that is, a plurality of them form only one circumference). It is possible to make it so that a plurality of them are provided on the circumference. In some cases, it is possible to provide a plurality of them on three or more circumferences.

空気逆止弁６は、内蓋体３に取り付けられている。空気逆止弁６は、空気を外部から内蓋体３の内側への一方向のみに流し得るものである。空気逆止弁６は、特に構造が限定されるものではないが、図９（ａ）に示すように、逆止弁室部材６１により形成される逆止弁室６１ａの中に逆止弁体６２が設けられているものを用いることができる。逆止弁室部材６１には、外部と逆止弁室６１ａとを連通し得る第１空気路６１ｂが形成され、また、空気逆止弁６が取り付けられる部材側（つまり内蓋体３側）に第２空気路６１ｃが形成されている。内蓋体３には、第２空気路６１ｃに対応する位置に空気路３ｃが形成され、それにより内蓋体３の内側と逆止弁室６１ａとが連通されている。また、逆止弁体６２は、逆止弁室部材６１の内壁に沿って摺動するように摺動部分６２ａが複数箇所（例えば、４箇所）設けられている。図９（ｂ）に示すのは摺動部分６２ａが含まれない切断面で切断した断面図である。 The air check valve 6 is attached to the inner lid body 3. The air check valve 6 can allow air to flow from the outside to the inside of the inner lid 3 in only one direction. The structure of the air check valve 6 is not particularly limited, but as shown in FIG. 9A, the check valve body is contained in the check valve chamber 61a formed by the check valve chamber member 61. Those provided with 62 can be used. The check valve chamber member 61 is formed with a first air passage 61b capable of communicating the outside with the check valve chamber 61a, and the member side to which the air check valve 6 is attached (that is, the inner lid 3 side). A second air passage 61c is formed in the air passage 61c. An air passage 3c is formed in the inner lid 3 at a position corresponding to the second air passage 61c, whereby the inside of the inner lid 3 and the check valve chamber 61a are communicated with each other. Further, the check valve body 62 is provided with a plurality of sliding portions 62a (for example, four locations) so as to slide along the inner wall of the check valve chamber member 61. FIG. 9B is a cross-sectional view taken along a cut surface that does not include the sliding portion 62a.

逆止弁体６２は、内蓋体３の内側の空気圧が外部と等しい或いは外部よりも大きいと、第１空気路６１ｂを塞ぐ（図９（ａ）、（ｂ）参照）。逆止弁体６２は、第１空気路６１ｂを塞いで逆止弁室部材６１に密接し易い材質のものであり、例えば、シリコーンゴムなどを用いることができる。逆止弁体６２は、内蓋体３の内側の空気圧が外部よりも小さいと、図９（ｃ）に示すように、第１空気路６１ｂを開放し、空気は、外部から逆止弁室６１ａを通って内蓋体３の内側に導入される。 The check valve body 62 closes the first air passage 61b when the air pressure inside the inner lid 3 is equal to or larger than the outside (see FIGS. 9A and 9B). The check valve body 62 is made of a material that closes the first air passage 61b and easily comes into close contact with the check valve chamber member 61. For example, silicone rubber or the like can be used. When the air pressure inside the inner lid 3 is smaller than that outside, the check valve body 62 opens the first air passage 61b as shown in FIG. 9 (c), and the air is introduced from the outside into the check valve chamber. It is introduced inside the inner lid 3 through 61a.

このような構成の携帯型浄水器１は、以下のようにして使用することができる。すなわち、先ず、浄水カートリッジ５付きの内蓋体３（及び外蓋体４）を容器本体２から取り外して水道水などの浄化前の水を注入する。その後、内蓋体３及び外蓋体４を装着すると、携帯型浄水器１は持ち運びが可能である。 The portable water purifier 1 having such a configuration can be used as follows. That is, first, the inner lid 3 (and the outer lid 4) with the water purification cartridge 5 is removed from the container body 2 and water before purification such as tap water is injected. After that, when the inner lid body 3 and the outer lid body 4 are attached, the portable water purifier 1 can be carried.

飲料時には、外蓋体４を内蓋体３から取り外し、携帯型浄水器１を逆さにして又は逆さ近くに傾けて容器本体２を圧縮すると、中の空気及び浄化前の水が加圧され、加圧された水は、浄水カートリッジ５の浄化前水流入孔５２ｅから流入して内部流水路５２ｄを通り、それからろ材５１を通過する。そのとき、浄化前の水に塩素や有機物などの不純物が含まれた場合、それらがろ材５１に捕捉され、浄水となる。浄水は、中空部５１ａ及び第２貫通孔５２ｂを通って第１浄水流出部３ｂの第１貫通孔３ｂａから流出する。 At the time of drinking, when the outer lid 4 is removed from the inner lid 3 and the portable water purifier 1 is turned upside down or tilted near the upside down to compress the container body 2, the air inside and the water before purification are pressurized. The pressurized water flows in from the pre-purification water inflow hole 52e of the water purification cartridge 5, passes through the internal flow channel 52d, and then passes through the filter medium 51. At that time, if the water before purification contains impurities such as chlorine and organic substances, they are captured by the filter medium 51 and become purified water. The purified water flows out from the first through hole 3ba of the first purified water outflow portion 3b through the hollow portion 51a and the second through hole 52b.

ここで、浄水カートリッジ５の浄化前水流入孔５２ｅは、ろ材収容体５２の一端面の近傍に偏在して設けられているため、図１０に示すように、容器本体２内の浄化前の水（図１０において符号Ｗ１で示す）が少なくなっても、浄化前水流入孔５２ｅの外側に水が有る限り、浄水カートリッジ５の外側の空気は、浄水カートリッジ５内には入ってこない。そうすると、容器本体２内の浄化前の水が少なくなっても、浄水に空気が混じったり浄水が流出し難くなったりすることなく、浄化前の水が多いときと同様な状態の浄水を流出することができる。浄水カートリッジの外側の空気が混じらない浄水は、衛生的でもある。これに対し、従来の携帯型浄水器では、浄水カートリッジの浄化前水流入孔は、ろ材収容体の側面の全体に設けられているため、容器本体内の浄化前の水が少なくなると、浄水カートリッジの外側の空気は、浄水カートリッジ５内に入り込み、ろ材を通過して浄水に混じることになる。また、そのとき、浄化前の水を加圧する空気の圧力は小さくなるので、浄水が流出し難くなる。 Here, since the pre-purification water inflow holes 52e of the water purification cartridge 5 are unevenly distributed in the vicinity of one end surface of the filter medium accommodating body 52, as shown in FIG. 10, the pre-purification water in the container body 2 is pre-purified water. Even if the amount (indicated by the reference numeral W1 in FIG. 10) decreases, the air outside the water purification cartridge 5 does not enter the water purification cartridge 5 as long as there is water outside the pre-purification water inflow hole 52e. Then, even if the amount of water in the container body 2 before purification is low, the purified water does not mix with air or the purified water does not easily flow out, and the purified water in the same state as when there is a large amount of water before purification flows out. be able to. Purified water that is immiscible with the air outside the water purification cartridge is also hygienic. On the other hand, in the conventional portable water purifier, the pre-purification water inflow hole of the water purification cartridge is provided on the entire side surface of the filter medium accommodating body. The air outside the water enters the water purification cartridge 5, passes through the filter medium, and mixes with the purified water. Further, at that time, the pressure of the air that pressurizes the water before purification becomes small, so that the purified water is less likely to flow out.

第１浄水流出部３ｂの第１貫通孔３ｂａから流出する浄水は、第１浄水流出部３ｂを口に含んで飲むことが可能である。また、外蓋体４をコップとして使用する場合は、浄水を外蓋体４に注いで飲むことが可能である。浄水を外蓋体４に注いで飲むと、より衛生的になる。なお、容器本体２の圧縮前及び圧縮時には、空気逆止弁６の第１空気路６１ｂは、塞がった状態であり、内部の空気或いは浄化前の水は、第１空気路６１ｂを通って外部に流出することはない。 The purified water flowing out from the first through hole 3ba of the first purified water outflow portion 3b can be drunk with the first purified water outflow portion 3b in the mouth. When the outer lid 4 is used as a cup, purified water can be poured into the outer lid 4 for drinking. If you pour purified water into the outer lid 4 and drink it, it will be more hygienic. Before and during compression of the container body 2, the first air passage 61b of the air check valve 6 is in a closed state, and the internal air or water before purification passes through the first air passage 61b to the outside. Will not leak to.

容器本体２の圧縮を終えると、浄水の流出が止まる。また、そうすると、容器本体２の形状が復元し、空気逆止弁６の第１空気路６１ｂが開放されて容器本体２（及び内蓋体３）の内側に空気が導入される。 When the compression of the container body 2 is completed, the outflow of purified water stops. Then, the shape of the container body 2 is restored, the first air passage 61b of the air check valve 6 is opened, and air is introduced into the container body 2 (and the inner lid 3).

携帯型浄水器１は、以下のようにすると、浄水カートリッジ５のろ材５１を洗浄可能にすることができる。 The portable water purifier 1 can make the filter medium 51 of the water purification cartridge 5 washable by doing the following.

第１浄水流出部３ｂの第１貫通孔３ｂａは、内蓋体３の内側からのみならず外側からも（図１においては内蓋体３の上側からも）、つまり逆向きでも、浄水カートリッジ５の第２浄水流出部５２ａが装着できるような構造とする。例えば、上記のように、第１浄水流出部３ｂの第１貫通孔３ｂａには、一対の支持片３ｂｂが対向して内壁面に設けられるようにし、第２浄水流出部５２ａには、一対の被支持片５２ａａが外壁面に設けられるような構造でそれが可能である。第２浄水流出部５２ａが内蓋体３の外側から第１浄水流出部３ｂの第１貫通孔３ｂａに装着されるときは、一対の被支持片５２ａａは、内蓋体３の外側から内側に向かって移動させられて一対の支持片３ｂｂの間を通過し、それから略９０度回動させられて一対の支持片３ｂｂの内側で重なり合う。 The first through hole 3ba of the first purified water outflow portion 3b is formed not only from the inside of the inner lid 3 but also from the outside (from the upper side of the inner lid 3 in FIG. 1), that is, even in the opposite direction, the water purification cartridge 5 The structure is such that the second purified water outflow portion 52a can be attached. For example, as described above, the first through hole 3ba of the first purified water outflow portion 3b is provided with a pair of support pieces 3bb facing each other on the inner wall surface, and the second purified water outflow portion 52a is provided with a pair of support pieces 3bb. This is possible with a structure in which the supported piece 52aa is provided on the outer wall surface. When the second purified water outflow portion 52a is attached to the first through hole 3ba of the first purified water outflow portion 3b from the outside of the inner lid body 3, the pair of supported pieces 52aa are from the outside to the inside of the inner lid body 3. It is moved towards and passes between the pair of support pieces 3bb, then is rotated approximately 90 degrees and overlaps inside the pair of support pieces 3bb.

ここで、一対の被支持片５２ａが略９０度回動させられて一対の支持片３ｂｂに重なり合うことで、浄水カートリッジ５が内蓋体３にその内側から及び外側から装着されると、浄水カートリッジ５を保持する指はそのままに手首を略９０度回すだけでよい。よって、浄水カートリッジ５と指とは最小限の接触で済むことになるので、浄水カートリッジのろ材５１を洗浄する際の不意な汚れ等の浄水カートリッジ５への付着を抑制することができる。 Here, when the pair of supported pieces 52a are rotated by approximately 90 degrees and overlap with the pair of supporting pieces 3bb so that the water purification cartridge 5 is attached to the inner lid 3 from the inside and the outside, the water purification cartridge 5 is attached. All you have to do is turn your wrist about 90 degrees while keeping the finger holding 5. Therefore, since the contact between the water purification cartridge 5 and the finger is minimized, it is possible to suppress the adhesion of unexpected stains and the like to the water purification cartridge 5 when cleaning the filter medium 51 of the water purification cartridge.

携帯型浄水器１を浄水が得られる通常の状態から、浄水カートリッジ５が洗浄可能な状態にするには、先ず、外蓋体４及び内蓋体３を容器本体２から取り外し、水道水を容器本体２注入する。浄水カートリッジ５を内蓋体３から分離させる。そして、浄水カートリッジ５の第２浄水流出部５２ａを内蓋体３の第１浄水流出部３ｂの第１貫通孔３ｂａに逆向きに（つまり、浄水カートリッジ５を内蓋体３に逆向きに）取り付けて、内蓋体３を容器本体２に装着する。そして、シンク等の場所で、図１１に示すように、携帯型浄水器１を逆さに又は斜めに傾けて容器本体２を圧縮すると、加圧された水道水（図１１において符号Ｗ２で示す）が、第１浄水流出部３ｂの第１貫通孔３ｂａから逆向きに浄水カートリッジ５の第２貫通孔５２ｂ及び中空部５１ａに流入し、ろ材５１を内側から外側に向かって通過して、浄水カートリッジ５の外に排出される。このとき、ろ材５１に補足され蓄積された不純物は浄水カートリッジ５の外に排出され、それとともに、ろ材５１の内側近傍は、水道水に含まれる塩素によって殺菌される。 In order to make the water purification cartridge 5 washable from the normal state where the portable water purifier 1 can obtain purified water, first, the outer lid 4 and the inner lid 3 are removed from the container body 2, and tap water is filled in the container. Body 2 Inject. The water purification cartridge 5 is separated from the inner lid 3. Then, the second purified water outflow portion 52a of the water purification cartridge 5 is oriented in the opposite direction to the first through hole 3ba of the first purified water outflow portion 3b of the inner lid body 3 (that is, the water purification cartridge 5 is oriented in the opposite direction to the inner lid body 3). After attaching, the inner lid 3 is attached to the container body 2. Then, as shown in FIG. 11, when the portable water purifier 1 is tilted upside down or diagonally to compress the container body 2 at a place such as a sink, pressurized tap water (indicated by reference numeral W2 in FIG. 11). Flows into the second through hole 52b and the hollow portion 51a of the water purification cartridge 5 in the opposite direction from the first through hole 3ba of the first water purification outflow portion 3b, passes through the filter medium 51 from the inside to the outside, and the water purification cartridge. It is discharged to the outside of 5. At this time, the impurities captured and accumulated in the filter medium 51 are discharged to the outside of the water purification cartridge 5, and at the same time, the vicinity of the inside of the filter medium 51 is sterilized by chlorine contained in tap water.

携帯型浄水器１は、また、以下のようにして浄水にミネラルを付加することができる。ここで、浄水カートリッジ５のろ材５１は、塩素や有機物などは捕捉するが、ミネラル（ナトリウム、カルシウム、マグネシウム、カリウムなど）は捕捉されないものを用いる。 The portable water purifier 1 can also add minerals to the purified water as follows. Here, the filter medium 51 of the water purification cartridge 5 uses a filter medium 51 that captures chlorine, organic substances, and the like, but does not capture minerals (sodium, calcium, magnesium, potassium, etc.).

携帯型浄水器１は、図１２に示すように、ミネラル溶出カートリッジ７を更に備えるようにし、浄水カートリッジ５のろ材収容体５２にミネラル溶出カートリッジ７が装着できるようにする。ミネラル溶出カートリッジ７は、セラミックス材７１とそれを収容する筒状のセラミックス材収容体７２を有する。セラミックス材７１は水に溶出するミネラルを含有している。セラミックス材収容体７２は、図１３（ａ）、（ｂ）に示すように、一端部に装着部７２ａを有している。ろ材収容体５２は、図１４に示すように、一端面の反対側の他端面に、ミネラル溶出カートリッジ７の装着部７２ａが装着され得る被装着部５２ｆを有している。ミネラルを含有するセラミックス材７１は、例えば、海底の土類から作られた自然由来のものとすることができる。また、セラミックス材収容体７２は、セラミックス材７１に浄化前の水が接触することができるように、通水孔７２ｂが多数設けられている。 As shown in FIG. 12, the portable water purifier 1 is further provided with a mineral elution cartridge 7, so that the mineral elution cartridge 7 can be attached to the filter medium accommodating body 52 of the water purification cartridge 5. The mineral elution cartridge 7 has a ceramic material 71 and a tubular ceramic material accommodating body 72 for accommodating the ceramic material 71. The ceramic material 71 contains minerals that elute into water. As shown in FIGS. 13 (a) and 13 (b), the ceramic material accommodating body 72 has a mounting portion 72a at one end. As shown in FIG. 14, the filter medium accommodating body 52 has a mounted portion 52f on which the mounting portion 72a of the mineral elution cartridge 7 can be mounted on the other end surface on the opposite side of one end surface. The mineral-containing ceramic material 71 can be, for example, naturally derived from the earth on the seabed. Further, the ceramic material accommodating body 72 is provided with a large number of water passage holes 72b so that the water before purification can come into contact with the ceramic material 71.

ろ材収容体５２の被装着部５２ｆは、例えば、一対の被装着部片５２ｆａが設けられ、セラミックス材収容体７２の装着部７２ａは、孔部７２ａａとそれに連続して内部で周方向に一定区間だけ形成された一対の差し込み部７２ａｂが設けられるようにすることができる。一対の被装着部片５２ｆａが一対の差し込み部７２ａｂに差し込まれることにより、ろ材収容体５２にミネラル溶出カートリッジ７が装着される。 The mounted portion 52f of the filter medium accommodating body 52 is provided with, for example, a pair of mounted portion pieces 52fa, and the mounting portion 72a of the ceramic material accommodating body 72 is continuously connected to the hole portion 72aa and a constant section in the circumferential direction. A pair of insertion portions 72ab formed only for can be provided. The mineral elution cartridge 7 is mounted on the filter medium accommodating body 52 by inserting the pair of mounted portion pieces 52fa into the pair of insertion portions 72ab.

ミネラル溶出カートリッジ７は、容器本体２内に貯留された浄化前の水に漬かると、セラミックス材７１からミネラル（ナトリウム、カルシウム、マグネシウム、カリウムなど）が溶出する。ミネラルは、浄水カートリッジ５のろ材５１を通過することができ、従って、第１浄水流出部３ｂの第１貫通孔３ｂａから流出する浄水に含まれるようにすることができる。ミネラルを含む浄水は、熱中症対策として有効である。 When the mineral elution cartridge 7 is immersed in unpurified water stored in the container body 2, minerals (sodium, calcium, magnesium, potassium, etc.) are eluted from the ceramic material 71. Minerals can pass through the filter medium 51 of the water purification cartridge 5, and therefore can be included in the purified water flowing out from the first through hole 3ba of the first purified water outflow portion 3b. Purified water containing minerals is effective as a measure against heat stroke.
