特許法第３０条第２項適用びわ湖環境ビジネスメッセ２０１９２０１９年１０月１６日～１８日Article 30, Paragraph 2 of the Patent Act applies Lake Biwa Environmental Business Messe 2019 October 16th to 18th, 2019

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, and water such as tap water is put into the container, and the unpurified water is purified (purified) by the water purification cartridge. Some portable water purifiers have pressurizing means. In a portable water purifier that has a pressurizing means, when the flexible pressurizing means is grasped and compressed, the unpurified water passes through the purification material (filter material) of the water purification cartridge, and at that time, the chlorine and organic substances contained in the water are removed. By trapping impurities such as, water becomes purified.

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 cylindrical container body that stores water before purification serves as a pressurizing means, and when in use, the container body is turned upside down or tilted nearly upside down. When 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 passes through the purified water outlet (adapter) provided on one side of the inside of the filter medium. ) flows out as purified water to the outside (into the mouth, etc.). A portable water purifier in which the container body serves as a pressurizing means has a compact structure and is suitable for use outdoors.

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。 In addition, 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 purified water outflow part, purified water flows out to the outside. Can be done. Furthermore, this portable water purifier can be used by first removing the water purification cartridge, injecting tap water into the container body, attaching the water purification cartridge in the opposite direction to the purified water outlet, and then turning it upside down or tilting it almost upside down to open the container body. When compressed, the pressurized tap water passes through the water purification outlet and from the inside to the outside of the filter media of the water purification cartridge. By doing so, the water purification cartridge can be cleaned to expel the impurities trapped and accumulated therein.

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。 EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated. As shown in FIG. 1, a portable water purifier 1 according to an 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 cylindrical shape having an opening and a bottom. Specifically, a flexible container is one that compresses and deforms when gripping the container body 2 and applying force, and restores its shape when the force is released. Thereby, the container body 2 becomes a pressurizing means. Although the material of the container body 2 is not particularly limited, for example, flexible polyethylene can be used. The container body 2 has an opening on one side (the upper side in FIGS. 1 and 2) and a bottom on the other side so as to contain unpurified water such as tap water. The bottom of the container body 2 becomes the bottom of the entire portable water purifier 1. The portable water purifier 1 can stand upright with its bottom facing down, as shown in FIG.

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。 An inner lid body 3, which will be described in detail later, is removably attached to one side (opening side) of the container body 2. Therefore, the container body 2 has a male thread 2a formed on the outer side near one end.

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。 Preferably, the container body 2 has two or more annular recesses 2b, 2b' formed on the side thereof. Then, when the container body 2 is gripped and compressed at the portion between the recesses 2b, 2b' and the bottom, the portion between the recesses 2b, 2b' and one end and the inner lid body 3 are compressed. The vicinity of the attachment part becomes difficult to deform. Thereby, the possibility of problems such as water leakage at the mounting portion of the inner lid body 3 can be eliminated.

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 body 3 has a female thread 3a formed on the inside near the end on the other side (lower side in FIG. 1), and the female thread 3a is connected to the male thread 2a of the container body 2. By screwing, the inner lid body 3 is attached so as to surround the outer side of the container body 2 near one end. Note that the inner lid body 3 (and the outer lid body 4) do not need to be flexible like the container body 2, and are usually hard (hard to deform). The material of the inner lid 3 (and outer lid 4) is not particularly limited, and for example, polypropylene or the like can be used.

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。 Moreover, the inner lid body 3 has a purified water outflow part (first purified water outflow part) 3b, as shown in FIGS. 1 and 3(a) and (b). The purified water outflow portion 3b protrudes outward (upward in FIGS. 1 and 3(b)). Further, the purified water outflow portion 3b is provided at the center of the end face. The first purified water outflow portion 3b may have a cylindrical shape or a prismatic cylindrical 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。 A through hole (first through hole) 3ba is provided in the axial direction inside the first purified water outflow portion 3b (see FIG. 3(a)). A second purified water outflow portion 52a, which will be described later, of the water purification cartridge 5 can be attached to the first through hole 3ba from the inside of the inner lid 3 (from the lower side of the inner lid 3 in FIGS. 1 and 3(b)). It has a structure. For example, a pair of support pieces 3bb are provided on the inner wall surface of the first through-hole 3ba of the first purified water outflow part 3b so as to face each other in order to attach the second purified water outflow part 52a of the water purification cartridge 5, A pair of supported pieces 52aa, which will be described in detail later, can be provided on the outer wall surface of the second purified water outflow portion 52a. The support piece 3bb is usually in the form 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 can be provided with a protrusion 4a on the inside so that the first through hole 3ba of the first purified water outflow portion 3b is plugged when the outer lid body 4 is attached to the inner lid body 3. Furthermore, as shown in FIG. 1, if the outer lid body 4 is attached at a portion surrounding the first purified water outflow portion 3b, it can be used as a cup when removed. Further, although it is difficult to use it as a cup, the outer lid body 4 can be attached to 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, as shown in FIGS. 5(a), (b), FIGS. 6(a), (b), FIGS. 7(a), (b), and FIGS. 8(a), (b), It has a filter medium 51 and a filter medium container 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. The filter medium 51 can be cylindrical. The material of the filter medium 51 is not particularly limited, but may be an activated carbon molded filter, a hollow fiber membrane, a flat membrane, a ceramic membrane, a laminated filter, a thread-wound filter, a metal filter, or the like. Further, the outer circumferential surface and inner circumferential surface of the filter medium 51 are generally covered with a thin nonwoven 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 cylindrical shape that accommodates the filter medium 51. The filter medium container 52 may have a cylindrical shape. Note that although not shown in the drawings, the filter medium container 52 is generally formed by arranging the filter medium 51 therein and then combining two members. Further, the filter medium 51 is generally bonded to the filter medium container 52 at both end surfaces (the upper and lower surfaces in FIGS. 7(a) and 7(b)).

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 container 52 has a purified water outflow part (second purified water outflow part) 52a. The second purified water outflow portion 52a protrudes outward (upward in FIG. 5(b), etc.) from one end surface (the upper surface in FIG. 5(b), etc.) of the filter medium container 52. The second purified water outflow portion 52a is provided at the center of one end surface of the filter medium container 52. A through hole (second through hole) 52b communicating with the hollow portion 51a of the filter medium 51 is formed in the inside of the second purified water outflow portion 52a in the axial direction.

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 section 52a has a structure that can be attached to the first through hole 3ba of the first purified water outflow section 3b from inside the inner lid body 3. For example, as described above, the first through hole 3ba of the first purified water outlet 3b is provided with a pair of support pieces 3bb facing each other on the inner wall surface, and the second purified water outlet 52a is provided with a pair of supporting pieces 3bb on the inner wall surface. The supported piece 52aa can be provided on the outer wall surface. The pair of supported pieces 52aa overlap the pair of support pieces 3bb, so that the second purified water outflow part 52a is attached to the first through hole 3ba of the first purified water outflow part 3b. Specifically, during installation, the pair of supported pieces 52aa are moved from the inside to the outside of the inner lid body 3, pass between the pair of support pieces 3bb, and then approximately 90 degrees (in plan view). The support pieces 3bb are rotated approximately 90 degrees and overlap each other on the outside (the upper side in FIG. 1) of the pair of support pieces 3bb. Further, the pair of supported pieces 52aa have a tapered end on the rotating side so that they can easily rotate and overlap, and a stopper 52ab is provided on the opposite end to prevent them from rotating too much. Further, the second purified water outflow portion 52a is provided with an O-ring 52ac on its outer wall surface, so that when the portable water purifier 1 is turned upside down or tilted nearly upside down and the container body 2 is compressed, the first Water is prevented from leaking through 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 container 52 has a spacer 52c (see FIG. 7(b)) on its inner wall surface, thereby forming an internal flow channel 52d between it and the filter medium 51 (specifically, its outer surface).

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 container 52 has an elongated pre-purification water inflow hole 52e on its circumferential surface into which water before purification 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 hole 52e is unevenly provided near one end surface of the filter medium container 52 where the second purified water outflow portion 52a is provided. The pre-purification water inflow hole 52e is provided, for example, in a portion that is at least half (more preferably ⅓) or less of the height of the filter medium container 52. Further, the pre-purification water inflow holes 52e may be arranged so that, for example, as shown in FIG. A plurality of them can be provided on the circumference. Depending on the case, it is also 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 allows air to flow in only one direction from the outside to the inside of the inner lid body 3. Although the structure of the air check valve 6 is not particularly limited, as shown in FIG. 62 can be used. A first air passage 61b is formed in the check valve chamber member 61 to communicate the outside and the check valve chamber 61a. A second air passage 61c is formed in the second air passage 61c. An air passage 3c is formed in the inner lid body 3 at a position corresponding to the second air passage 61c, thereby communicating the inside of the inner lid body 3 and the check valve chamber 61a. Further, the check valve body 62 is provided with a plurality of sliding portions 62a (for example, four positions) so as to slide along the inner wall of the check valve chamber member 61. FIG. 9(b) is a cross-sectional view taken along a cut plane 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 body 3 is equal to or greater than the outside pressure (see FIGS. 9(a) and 9(b)). 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, and may be made of, for example, silicone rubber. When the air pressure inside the inner lid body 3 is lower than that outside, the check valve body 62 opens the first air passage 61b as shown in FIG. 9(c), and air flows from the outside into the check valve chamber. 61a and is introduced inside the inner lid body 3.

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 in the following manner. That is, first, the inner lid 3 (and outer lid 4) with the water purification cartridge 5 attached thereto is removed from the container body 2, and unpurified water such as tap water is poured into the container. Thereafter, when the inner lid 3 and the outer lid 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。 When drinking, the outer lid 4 is removed from the inner lid 3 and the portable water purifier 1 is turned upside down or tilted nearly upside down to compress the container body 2, which pressurizes the air and unpurified water inside. The pressurized water flows from the pre-purification water inlet 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 or organic substances, they are captured by the filter medium 51 and become purified water. Purified water passes through the hollow portion 51a and the second through hole 52b and flows out from the first through hole 3ba of the first purified water outflow portion 3b.

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-purified water inflow hole 52e of the water purification cartridge 5 is provided unevenly near one end surface of the filter medium container 52, as shown in FIG. (Denoted by reference numeral W1 in FIG. 10) decreases, as long as there is water outside the pre-purification water inlet 52e, the air outside the water purification cartridge 5 will not enter the water purification cartridge 5. In this way, even if the amount of unpurified water in the container body 2 decreases, air will not be mixed with the purified water or the purified water will not flow out easily, and the purified water will flow out in the same state as when there was a large amount of unpurified water. be able to. Purified water that is not mixed with air outside the water purification cartridge is also hygienic. On the other hand, in conventional portable water purifiers, the unpurified water inflow hole of the water purification cartridge is provided on the entire side surface of the filter medium container, so when the amount of unpurified water in the container body decreases, the water purification cartridge The air outside enters the water purification cartridge 5, passes through the filter medium, and mixes with the purified water. Furthermore, at this time, the pressure of the air that pressurizes the water before purification becomes small, making it difficult for the purified water 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 part 3b can be drunk by holding the first purified water outflow part 3b in the mouth. Further, when the outer lid body 4 is used as a cup, it is possible to pour purified water into the outer lid body 4 and drink it. Pour purified water into the outer lid body 4 and drink it to make it more hygienic. Note that 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. It will not leak out.

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 is stopped. Moreover, when doing so, 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 inside of the container body 2 (and the inner lid body 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。 In the portable water purifier 1, the filter medium 51 of the water purification cartridge 5 can be cleaned in the following manner.

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 can be opened 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 reverse direction. 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 outlet 3b is provided with a pair of support pieces 3bb facing each other on the inner wall surface, and the second purified water outlet 52a is provided with a pair of supporting pieces 3bb on the inner wall surface. 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 move inward from the outside of the inner lid body 3. The support pieces 3bb are moved toward each other and pass between the pair of support pieces 3bb, and then rotated approximately 90 degrees to overlap 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 approximately 90 degrees and overlap the pair of support pieces 3bb, and the water purification cartridge 5 is attached to the inner lid body 3 from the inside and the outside, the water purification cartridge All you have to do is turn your wrist approximately 90 degrees while keeping the finger holding the number 5 as it is. Therefore, since there is minimal contact between the water purification cartridge 5 and the finger, it is possible to suppress unexpected dirt and the like from adhering 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。 To change the portable water purifier 1 from the normal state in which purified water is obtained to the state in which the water purification cartridge 5 can be cleaned, first remove the outer lid 4 and the inner lid 3 from the container body 2, and pour tap water into the container. Inject main body 2. The water purification cartridge 5 is separated from the inner lid body 3. Then, the second purified water outflow portion 52a of the water purification cartridge 5 is placed 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 placed in the opposite direction to the inner lid body 3). Attach the inner lid body 3 to the container body 2. Then, at a place such as a sink, as shown in FIG. 11, when the portable water purifier 1 is turned upside down or tilted diagonally to compress the container body 2, pressurized tap water (indicated by the symbol W2 in FIG. 11) is generated. The water flows in the opposite direction from the first through hole 3ba of the first purified water outflow portion 3b into the second through hole 52b and the hollow portion 51a of the water purifying cartridge 5, passes through the filter medium 51 from the inside to the outside, and is removed from the water purifying cartridge. It is discharged 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 the chlorine contained in the 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 purified water as follows. Here, the filter medium 51 of the water purification cartridge 5 is one that captures chlorine, organic matter, etc., 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 further includes a mineral elution cartridge 7, so that the mineral elution cartridge 7 can be attached to the filter medium housing 52 of the water purification cartridge 5. The mineral elution cartridge 7 has a ceramic material 71 and a cylindrical ceramic material container 72 that accommodates the ceramic material 71. The ceramic material 71 contains minerals that dissolve in water. The ceramic material container 72 has a mounting portion 72a at one end, as shown in FIGS. 13(a) and 13(b). As shown in FIG. 14, the filter medium container 52 has a mounting portion 52f on the other end surface opposite to one end surface, into which the mounting portion 72a of the mineral elution cartridge 7 can be mounted. The ceramic material 71 containing minerals can be of natural origin, for example, made from earth on the ocean floor. Further, the ceramic material container 72 is provided with a large number of water passage holes 72b so that 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 attachment portion 52f of the filter medium container 52 is provided with, for example, a pair of attachment portions 52fa, and the attachment portion 72a of the ceramic material container 72 is provided with a hole 72aa and a constant section in the circumferential direction continuous therewith. A pair of insertion portions 72ab may be provided. The mineral elution cartridge 7 is attached to the filter medium container 52 by inserting the pair of attachment 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 can therefore be included in the purified water flowing out from the first through hole 3ba of the first purified water outflow section 3b. Purified water containing minerals is effective as a measure against heatstroke.
