Description

液剤混合噴射器Liquid mixture injector
　本発明は、主に園芸や農業に用いられる液剤混合噴射器であって、給水設備に接続されて、この給水設備から供給される水に第二の液体を混合して噴射する液剤混合噴射器に関する。 The present invention is a liquid mixture injector mainly used in horticulture or agriculture, and is connected to a water supply facility and mixes and injects a second liquid into water supplied from the water supply facility. About.
　従来の園芸や農業においては、給水設備から供給される水が通過する主流路を内部に形成し、主流路の先端に水を噴出する噴射口を形成し、主流路を開閉することができる流量制御弁を設けた水の噴射器であって、液体肥料などの第二の液体を水に混合して噴射する液剤混合噴射器が用いられてきた。
　この液剤混合噴射器は、第二の液体を収容する液剤タンクと、この液剤タンクから主流路へ第二の液体を導入する液剤流路とを備え、第二の液体を水に混合して噴射口から噴射していた。
　水に混合される第二の液体としては、液体肥料、農薬その他の薬剤や、洗車等に用いる洗剤など、水以外の様々な液体が用いられていた。 In conventional horticulture and agriculture, the main flow path through which the water supplied from the water supply facility passes is formed inside, the injection port for jetting water is formed at the tip of the main flow path, and the flow rate that can open and close the main flow path 2. Description of the Related Art A water injector provided with a control valve, which is a liquid agent mixing injector that mixes and injects a second liquid such as liquid fertilizer with water, has been used.
The liquid agent mixing injector includes a liquid agent tank that stores a second liquid and a liquid agent channel that introduces the second liquid from the liquid agent tank to the main channel, and the second liquid is mixed with water and injected. It was spraying from the mouth.
As the second liquid to be mixed with water, various liquids other than water, such as liquid fertilizers, agricultural chemicals and other chemicals, and detergents used for car washing and the like have been used.
　このような液剤混合噴射器として、特許文献１には、主流路の経路中に口径の極細い部分を設けて、その下流側を大径にして負圧発生部を設け、液剤タンクからの液剤流路をこの負圧発生部に接続して、通水する際に発生する負圧によって第二の液体を主流路に導入し、水に混合して噴射するものが記載されている。
　また、特許文献２には、特許文献１と同様に負圧発生部を設けた液剤混合噴射器であって、この負圧発生部に、液剤流路だけでなく、主流路から分岐し開閉弁を設けたバイパス流路をも接続したものが記載されている。この液剤混合噴射器では、開閉弁を開放したときには主流路の水量が減って負圧が低下するとともに負圧によってバイパス流路からの水も主流路に導入されることになるため、液在流路から主流路に導入される第二の液体の量を調整することができた。 As such a liquid agent mixing injector, Patent Document 1 discloses that a liquid agent from a liquid agent tank is provided in which a portion with an extremely narrow diameter is provided in the path of the main flow path, a negative pressure generator is provided with a large diameter on the downstream side. There is a description that a flow path is connected to this negative pressure generating section, a second liquid is introduced into the main flow path by a negative pressure generated when water flows, and the liquid is mixed and ejected.
Further, Patent Document 2 is a liquid agent mixing injector provided with a negative pressure generating part as in Patent Document 1, and this negative pressure generating part branches not only from the liquid agent flow path but also from the main flow path to open and close the valve. The thing which connected also the bypass flow path which provided was described. In this liquid mixture injector, when the on-off valve is opened, the amount of water in the main channel decreases, the negative pressure decreases, and water from the bypass channel is also introduced into the main channel by the negative pressure. The amount of the second liquid introduced from the channel into the main channel could be adjusted.
　さらに、特許文献３には、上記負圧発生部の代わりにエアー式エジェクタやポンプを用いて、液剤流路から主流路に第二の液体を導入するようにしたものが記載されている。
　また、特許文献４には、液剤流路の経路中に、液剤流路を開閉する開閉弁または液剤流路の口径を絞るニードル弁（液剤流路弁）を設けたものが記載されている。
　特許文献５には、特許文献１と同様に負圧発生部を設けた液剤混合噴射器であって、主流路から分岐する分岐流路（第二系統）によって液剤タンク内に水を放出して、液剤タンク内の第二の液体を加圧するものが記載されている。 Further, Patent Document 3 describes a configuration in which a second liquid is introduced from a liquid agent flow channel into a main flow channel using an air ejector or a pump instead of the negative pressure generating unit.
Japanese Patent Application Laid-Open No. H10-228667 describes a liquid agent passage provided with an open / close valve for opening and closing the liquid agent passage or a needle valve (liquid agent passage valve) for reducing the diameter of the liquid agent passage.
Patent Document 5 discloses a liquid agent mixing injector provided with a negative pressure generating portion as in Patent Document 1, and discharges water into the liquid agent tank by a branch channel (second system) that branches from the main channel. The one that pressurizes the second liquid in the liquid tank is described.

　特許文献１などの液剤混合噴射器では、流量制御弁の開度を調節して水の噴射量を調整できるが、この流量制御弁の操作により主流路の水の流量が増減すると、主流路の水圧も増減して第二の液体の導入量が変化するため、噴射される混合水（水に第二の液体を混合したもの）の濃度が変化してしまう。園芸や農業において液体肥料や農薬などを混合して散布する場合、所望の値に対して濃度が不足すると液剤の効果が不十分となってしまい、逆に濃度が過剰になると作物に悪影響を与えたり液剤消費量の浪費を生じたりしてしまっていた。 In the liquid agent mixing injector of Patent Document 1 or the like, the amount of water injection can be adjusted by adjusting the opening degree of the flow control valve. Since the water pressure also increases or decreases and the amount of the second liquid introduced changes, the concentration of the jetted mixed water (the mixture of the second liquid and water) changes. When mixing and spraying liquid fertilizers and pesticides in horticulture or agriculture, if the concentration is insufficient for the desired value, the effect of the solution will be insufficient, and conversely, if the concentration is excessive, the crop will be adversely affected. Or waste of liquid consumption.
　また、従来の園芸用の水噴射器には、先端に二種以上の噴射口を設けて、ストレート噴射、シャワー噴射など二以上の噴射形状を切り換えることができる噴射切換弁を設けたものがあった。
　液剤混合噴射器において、このような噴射形状を切り換えられるように構成した場合にも、切り換えの際に噴射口の総面積や主流路の通水抵抗が変化することにより、主流路の水の流量が増減し、主流路の水圧も増減して第二の液体の導入量が変化するため、噴射される混合水の濃度が変化してしまっていた。 In addition, some conventional horticultural water injectors are provided with an injection switching valve that is provided with two or more injection ports at the tip and can switch between two or more injection shapes such as straight injection and shower injection. It was.
Even when the liquid mixture injector is configured so that the injection shape can be switched, the flow rate of the water in the main channel is changed by changing the total area of the injection port and the water flow resistance of the main channel at the time of switching. However, since the amount of the second liquid introduced changes due to the increase or decrease of the water pressure in the main channel, the concentration of the mixed water to be injected has changed.
　このような場合、特許文献２のバイパス流路を開閉したり、特許文献３のポンプ等を操作したり、特許文献４の液剤流路弁を操作したりすることで、主流路の水圧の変化に合わせて第二の液体の導入量を調整することもできるが、手動で第二の液体の導入量を調整する手間がかかるとともに、水の流量に合わせて第二の液体の導入量を適当に調整することは困難であった。 In such a case, a change in the water pressure of the main flow path can be achieved by opening and closing the bypass flow path of Patent Document 2, operating the pump of Patent Document 3, etc., or operating the liquid flow path valve of Patent Document 4. Although the amount of the second liquid introduced can be adjusted according to the flow rate, it takes time and effort to manually adjust the amount of the second liquid introduced, and the amount of the second liquid introduced is appropriately adjusted according to the water flow rate. It was difficult to adjust to.
　特許文献５の液剤混合噴射器では、急に主流路の水圧が高まると、水が主流路から第二系統を通過し、液剤タンクに流出して内部を加圧し、第二の液体を主流路側へ加圧することにより、主流路に導入される第二の液体の水に対する比率を調整することができる可能性はある。
　しかしながら、水が第二系統を経て順次液剤タンクに流入するため、液剤タンク中で第二の液体の濃度が徐々に低下することになり、噴射される混合水も徐々に薄くなってしまうという問題があった。 In the liquid agent mixing injector of Patent Document 5, when the water pressure of the main flow path suddenly increases, water passes through the second system from the main flow path, flows out into the liquid agent tank, pressurizes the inside, and the second liquid is supplied to the main flow path side. There is a possibility that the ratio of the second liquid introduced into the main channel to the water can be adjusted.
However, since water sequentially flows into the liquid agent tank via the second system, the concentration of the second liquid gradually decreases in the liquid agent tank, and the jetted mixed water also becomes gradually thinner. was there.
　本発明は上記問題点を解決するためになされたものであり、主流路を通過する水圧が増減したときに、これに合わせて主流路に導入される第二の液体の量を調整することができ、噴射される混合水の濃度をほぼ一定に保持することのできる液剤混合噴射器を提供することを課題とする。 The present invention has been made to solve the above problems, and when the water pressure passing through the main channel increases or decreases, the amount of the second liquid introduced into the main channel can be adjusted accordingly. An object of the present invention is to provide a liquid mixture injector that can maintain the concentration of the injected mixed water substantially constant.

It is connected to the tip. The restraining member 4 is formed to be screwable with the base end portion, and the hose 2 can be attached to and detached from the liquid agent mixing injector 1.
As shown in FIG. 5, the liquid agent mixing injector 1 is formed with a substantially L-shaped main flow path 5 that passes through the inside from the base end portion to the tip end. A watering plate 7 (see FIGS. 3 and 4) provided with an injection port 6 made of a hole is attached.
Hereinafter, the part which forms this main flow path 5 among the liquid agent mixing injectors 1 is called the injector main body 8. The injector body 8 is configured by connecting a plurality of members including pipe elements.

Curable resins) and elastomers (thermoplastic elastomers composed of hard segments and soft segments, such as silicon-based and urethane-based) can be used, but thermoplastic resins are particularly preferable in terms of moldability and manufacturing cost.
O- rings 18 and 19 are preferably made of vulcanized rubber (NBR, EPDM, fluorine rubber, silicon rubber, etc.) or elastomer, and vulcanized rubber is particularly preferable from the viewpoint of sealing and deformation resistance. preferable.
　このような液剤混合噴射器１では、図５に示すように、流量制御弁９の操作レバー９ｄを握りこんで開弁すると、水が主流路５を通過して噴射口６から噴射されるとともに、主流路５を通過する水の一部は分岐流路１３を通って水タンク１５に流れ込む。
　水タンク１５内部の水位が上昇すると、水タンク１５内の空気が押し出され、空気流路１７を経て液剤タンク１０に流入する。このようにして液剤タンク１０に流入した空気によって、液剤タンク１０内部の気圧が上昇し、第二の液体を加圧して液剤流路１１ｃから主流路５に導入する。 In such a liquid mixture injector 1, as shown in FIG. 5, when the operation lever 9 d of the flow rate control valve 9 is grasped and opened, water passes through the main flow path 5 and is injected from the injection port 6. A part of the water passing through the main flow path 5 flows into the water tank 15 through the branch flow path 13.
When the water level in the water tank 15 rises, the air in the water tank 15 is pushed out and flows into the liquid agent tank 10 through the air flow path 17. The air flowing into the liquid agent tank 10 in this way raises the atmospheric pressure inside the liquid agent tank 10, pressurizes the second liquid, and introduces the second liquid from the liquid agent channel 11 c into the main channel 5.
　これにより、液剤混合噴射器１では、特別の負圧発生部を設けなくても、自動的に第二の液体を水に混合して噴射することができる。
　また、流量制御弁９の操作や給水設備の操作によって主流路５を通過する水流量が増減した場合にも、これに応じて主流路５から分岐流路１３に流れ込む水の量が増減し、水が空気を液剤タンク１０側へ加圧する力および空気が液剤タンク１０で第二の液体を加圧する力も増減するため、水に混合される第二の液体の量を追従させることができて、噴射される混合水の濃度をほぼ一定に保持することができる。 Thereby, in the liquid agent mixing injector 1, the second liquid can be automatically mixed with water and injected without providing a special negative pressure generating section.
Further, when the flow rate of water passing through the main flow path 5 is increased or decreased by the operation of the flow control valve 9 or the operation of the water supply equipment, the amount of water flowing from the main flow path 5 to the branch flow path 13 is increased or decreased accordingly. Since the force by which water pressurizes the air toward the liquid agent tank 10 and the force by which the air pressurizes the second liquid in the liquid agent tank 10 also increase / decrease, the amount of the second liquid mixed in the water can be followed. The concentration of the injected mixed water can be kept almost constant.
　なお、図５に示すように、分岐流路１３に分岐流路延長部材６３を接続して、水タンク１５の内部の底部付近まで延長してもよい。分岐流路延長部材６３としては管状部材を使用でき、管状部材の材質としては金属又はポリマー樹脂部材を使用でき、塩化ビニル樹脂からなるホース部材が好適である。その他に、加硫ゴム等の弾性材料を使用してもよい。
　分岐流路１３に分岐流路延長部材６３を接続して水タンク１５の底部付近まで延長したときには、流量制御弁９の操作や給水設備の操作によって主流路５を通過する水流量が増減した場合に、これに応じて主流路５から分岐流路１３に流れ込む水の量が増減し、且つ、分岐流路１３から主流路５へ水を逆流させることも可能となり、水が空気を液剤タンク１０側へ加圧する力および空気が液剤タンク１０で第二の液体を加圧する力の増減を調整する効果がより一層高まり、水に混合される第二の液体の量を主流路の水量により追従させることができて、噴射される混合水の濃度をさらに一定に保持することができる。
　また、流量制御弁９にて主流路５を閉止するとき、および閉鎖した後において、分岐流路延長部材６３の下側開口が水タンク１５の水中に存在しているため、分岐流路１３を通して水タンク１５から主流路５に空気が流入することを防止できる。なお、これらの効果を高めるため、分岐流路延長部材６３の下側開口の最も上側の位置と、水タンク１５の内部の底部との距離は、２０ｍｍ以下とするのが好ましく、さらに１０ｍｍ以下、特に５ｍｍ以下とするのが好ましい。 As shown in FIG. 5, a branch channel extension member 63 may be connected to the branch channel 13 and extended to the vicinity of the bottom inside the water tank 15. A tubular member can be used as the branch flow path extending member 63. A metal or polymer resin member can be used as the material of the tubular member, and a hose member made of vinyl chloride resin is suitable. In addition, an elastic material such as vulcanized rubber may be used.
When the branch channel extension member 63 is connected to the branch channel 13 and extended to the vicinity of the bottom of the water tank 15, the flow rate of water passing through the main channel 5 increases or decreases due to the operation of the flow control valve 9 or the operation of the water supply equipment. Accordingly, the amount of water flowing from the main flow path 5 to the branch flow path 13 is increased or decreased accordingly, and it is possible to reverse the flow of water from the branch flow path 13 to the main flow path 5. The effect of adjusting the increase / decrease in the force of pressurizing to the side and the force of the air pressurizing the second liquid in the liquid agent tank 10 is further enhanced, and the amount of the second liquid mixed with water is made to follow the amount of water in the main channel. In addition, the concentration of the mixed water to be injected can be kept more constant.
Further, when the main flow path 5 is closed by the flow control valve 9 and after it is closed, the lower opening of the branch flow path extending member 63 exists in the water of the water tank 15. Air can be prevented from flowing into the main flow path 5 from the water tank 15. In order to enhance these effects, the distance between the uppermost position of the lower opening of the branch flow path extension member 63 and the bottom inside the water tank 15 is preferably 20 mm or less, and further 10 mm or less, In particular, the thickness is preferably 5 mm or less.
　分岐流路延長部材６３を設けることにより、水タンク１５から主流路５に水を流すことも可能になるので、流量制御弁９を閉じたときに、水タンク１５に溜まった水を分岐流路１３と主流路５を通じて噴射口６から外部に排出することができ、つまり、装置を分解することなく水タンク１５に溜まった水を外部に排出できる水排出機構を実現することができる。
　言い換えると、分岐流路延長部材６３を設けることで、流量制御弁９を閉じたときに、水タンクに溜まった水を自動的に外部に排出する水排出機構を実現することができる。 By providing the branch flow path extending member 63, it becomes possible to flow water from the water tank 15 to the main flow path 5. Therefore, when the flow control valve 9 is closed, the water accumulated in the water tank 15 is allowed to flow. 13 and the main flow path 5 can be discharged to the outside from the injection port 6, that is, a water discharge mechanism that can discharge the water accumulated in the water tank 15 to the outside without disassembling the apparatus can be realized.
In other words, by providing the branch flow path extending member 63, it is possible to realize a water discharge mechanism that automatically discharges water accumulated in the water tank to the outside when the flow control valve 9 is closed.

It differs from the first embodiment in three configurations: a valve is provided, and a negative pressure generating part is provided in the vicinity of a joining part between the main flow path 5 and the liquid agent flow path 11c.
It is effective as an embodiment of the present invention that only one of these three configurations is added to the first embodiment, or two are combined and added to the first embodiment. Is.
　第二実施形態の液剤混合噴射器は、図１１に点線矢印で示した空気流路１７を有している。
　図１０、図１１、図１２に示すように、水位感知弁は、水タンク１５内部の水位が所定高さ以上に上昇すると空気流路１７を閉鎖して、水タンク１５の水が液剤タンク１０に混入することを防止するものである。
　この水位感知弁は、図１２に示すように、空気流路１７の一部兼弁座としての役割を備えた流路分岐部材１４と、弁体としてフロート部材２０とからなる。 The liquid agent mixing injector of the second embodiment has an air flow path 17 indicated by a dotted arrow in FIG.
As shown in FIGS. 10, 11, and 12, the water level detection valve closes the air flow path 17 when the water level inside the water tank 15 rises to a predetermined height or more, and the water in the water tank 15 is allowed to flow into the liquid agent tank 10. It prevents it from being mixed in.
As shown in FIG. 12, the water level detection valve includes a flow path branching member 14 serving as a part of the air flow path 17 and a valve seat, and a float member 20 as a valve body.
　フロート部材２０は、フロート上部材とフロート下部材との上下二部材を組み立ててなり、全体として密度が水よりも小さく作られ、水に浮くようになっている。
　フロート下部材は、後述するフロート保持部材２２の下端から水タンク内に露出する略円柱状の水位感知部２０ａと、この水位感知部２０ａの上に設けられた大径有底円筒状の結合部とからなる。
　フロート上部材は、大径有蓋円筒状に形成された結合部と、この結合部の上に設けられた略円柱状の弁体部２０ｂとからなる。弁体部２０ｂの最下部には、Ｏリング２１を周設している。また、弁体部２０ｂの周壁には溝（図示せず）を刻設するなどして、弁開状態で水タンク１５内部の空気が空気流路１７に流れ込むことができるようになっており、第二実施形態では弁体部２０ｂの周壁に該弁体部２０ｂの軸延在方向（図１１での上下方向）に４本の溝を設けることにより、弁体部２０ｂを断面略十字形に形成している。 The float member 20 is formed by assembling two upper and lower members of a float upper member and a float lower member, and the density is made smaller than water as a whole and floats on water.
The float lower member includes a substantially cylindrical water level sensing unit 20a exposed in the water tank from a lower end of a float holding member 22 described later, and a large-diameter bottomed cylindrical coupling provided on the water level sensing unit 20a. It consists of.
The float upper member includes a coupling portion formed in a large-diameter covered cylindrical shape, and a substantially columnar valve body portion 20b provided on the coupling portion. An O-ring 21 is provided around the lowermost part of the valve body 20b. Further, a groove (not shown) is engraved in the peripheral wall of the valve body portion 20b so that air inside the water tank 15 can flow into the air flow path 17 in the valve open state. In the second embodiment, the valve body portion 20b has a substantially cross-shaped cross section by providing four grooves in the axial extending direction (vertical direction in FIG. 11) of the valve body portion 20b on the peripheral wall of the valve body portion 20b. Forming.
　フロート上部材とフロート下部材とは、それぞれの結合部同士を螺着や接合などによって一体に組み付け、その内部に空気を収容する空間を設けて、フロート部材２０全体の密度を小さくしている。
　フロート部材２０は、このような内部に空気などの気体を封じ込めた中空構造とするほか、水より密度の小さい材料から形成してもよく、要するに、水に浮く構造及び／又は材質とすればよい。なお、フロート部材を低コストで実現するためには、内部に空気などの気体を封じ込めた中空構造とするのがよい。 The float upper member and the float lower member are integrally assembled with each other by screwing, joining, or the like, and a space for accommodating air is provided therein to reduce the density of the float member 20 as a whole.
The float member 20 may have a hollow structure in which a gas such as air is enclosed, or may be formed of a material having a density lower than that of water. In short, the float member 20 may have a structure and / or material that floats on water. . In addition, in order to implement | achieve a float member at low cost, it is good to set it as the hollow structure which enclosed gas, such as air, inside.
　流路分岐部材１４は、主流路５の一部を構成するとともに、主流路５から分岐する分岐流路１３を形成し、この分岐流路１３の終端に、水タンク１５の蓋となる蓋部１４ａを設けている点は第一実施形態と同様である。
　第二実施形態の流路分岐部材１４では、空気流路１７を設けているとともに、図６、図１２に示すように、この空気流路の一部にフロート部材２０の弁体部２０ｂが昇降できる昇降スペース１４ｃを設けている。 The flow path branching member 14 constitutes a part of the main flow path 5 and forms a branch flow path 13 branched from the main flow path 5. A lid portion serving as a lid of the water tank 15 is formed at the end of the branch flow path 13. The point provided with 14a is the same as in the first embodiment.
In the flow path branching member 14 of the second embodiment, an air flow path 17 is provided, and as shown in FIGS. 6 and 12, the valve body portion 20b of the float member 20 is moved up and down in a part of the air flow path. A liftable space 14c is provided.
　また、図１０、図１２に示すように、流路分岐部材１４の蓋部１４ａの直下には、フロート保持部材２２が設けられている。
　このフロート保持部材２２は、水タンク１５の上部に張り渡されて、フロート部材２０を所定の高さに保持することができ、また、フロート部材２０の水位感知部２０ａが保持される位置には孔を穿設して、水位感知部２０ａが水タンク内に露出するようにしている。
　フロート保持部材２２には、通気口２２ａが形成されており、水タンク１５内部と流路分岐部材１４の空気流路１７とを連通させる流路を形成している。
　また、フロート保持部材２２と蓋部１４ａとの間には所定の間隙を設けて、水位の上昇に応じてフロート部材２０が浮き上がることができるようにしている。 As shown in FIGS. 10 and 12, a float holding member 22 is provided immediately below the lid portion 14 a of the flow path branching member 14.
This float holding member 22 is stretched over the upper part of the water tank 15 to hold the float member 20 at a predetermined height, and at a position where the water level sensing unit 20a of the float member 20 is held. A hole is formed so that the water level sensing unit 20a is exposed in the water tank.
The float holding member 22 is formed with a vent hole 22a, which forms a flow path that allows the inside of the water tank 15 and the air flow path 17 of the flow path branching member 14 to communicate with each other.
Further, a predetermined gap is provided between the float holding member 22 and the lid portion 14a so that the float member 20 can be lifted as the water level rises.
　このような水位感知弁を設けたことにより、第二実施形態の液剤混合噴射器２３では、第二の液体を水に混合する際に、水が主流路５から水タンク１５に流れ込んで水位が所定高さ以上になると、フロート部材２０の水位感知部２０ａが水面に接触し、水位の上昇に応じてフロート部材２０が上昇する。
　フロート部材２０の上昇により、弁体部２０ｂの最下部に周設されたＯリング２１が、蓋部に設けられた空気流路１７を閉塞するため（図１１参照）、水タンク１５内部の水位の上昇により水が空気流路１７を通って液剤タンク１０に混入してしまうことがない。
　これにより、液剤タンク１０の第二の液体の濃度を一定に保つことができるため、噴射される混合水の濃度も一定に保つことができる。
　Ｏリング２１は、Ｏリング１８、１９と同様に、加硫ゴム（ＮＢＲ、ＥＰＤＭ、フッ素系ゴム、シリコン系ゴム等）またはエラストマー製のものを用いるのが好ましく、密閉性の観点から特に加硫ゴムが好ましい。 By providing such a water level detection valve, in the liquid agent mixing injector 23 of the second embodiment, when the second liquid is mixed with water, water flows into the water tank 15 from the main flow path 5 and the water level is adjusted. If it becomes more than predetermined height, the water level detection part 20a of the float member 20 will contact the water surface, and the float member 20 will raise according to a raise of a water level.
As the float member 20 rises, the O-ring 21 provided around the lowermost part of the valve body 20b closes the air flow path 17 provided in the lid (see FIG. 11). As a result, the water does not mix with the liquid agent tank 10 through the air flow path 17.
Thereby, since the density | concentration of the 2nd liquid of the liquid agent tank 10 can be kept constant, the density | concentration of the injected mixed water can also be kept constant.
The O-ring 21 is preferably made of vulcanized rubber (NBR, EPDM, fluorine-based rubber, silicon-based rubber, etc.) or an elastomer, like the O- rings 18 and 19, and is particularly vulcanized from the viewpoint of hermeticity. Rubber is preferred.
　さらに、第二実施形態では、液剤流路１１ｃ中に液剤流路弁を設けており、一定の水量の噴射を行っているときに、水に混合される第二の液体の量を増減させて、混合水の濃度を調整することができる。
　この液剤流路弁は、図１０に示す液剤流路１１ｃを略垂直に貫通する回転式の弁体２４と、この弁体２４に取り付けられる操作用つまみ２５（図９参照）とからなる。 Further, in the second embodiment, a liquid agent flow path valve is provided in the liquid agent flow path 11c, and when the injection of a constant amount of water is performed, the amount of the second liquid mixed with water is increased or decreased. The concentration of mixed water can be adjusted.
This liquid passage valve includes a rotary valve body 24 that passes through the liquid passage 11c shown in FIG. 10 substantially vertically and an operation knob 25 (see FIG. 9) attached to the valve body 24.
　図１３、図１４に示すように、液剤流路弁の弁体２４は、液剤流路１１ｃを閉塞する略円錐形状に形成されて、中央に水が通過する貫通孔２４ａを穿設している。この貫通孔２４ａの両端では、貫通孔２４ａから弁体２４の周方向に向かって一対の調整溝２４ｂ、２４ｃを刻設している。
　入口側すなわち水タンク側の調整溝２４ｂは、貫通孔２４ａの向きに対しておよそ９０度の範囲まで延設され、全範囲において一定の幅および深さで形成されている。
　出口側すなわち主流路側の調整溝２４ｃは、上流側の調整溝２４ｂと対称に、貫通孔２４ａの向きに対しておよそ９０度の範囲まで延設されるが、貫通孔２４ａから遠ざかるにつれて浅く狭く形成されている。 As shown in FIGS. 13 and 14, the valve body 24 of the liquid agent passage valve is formed in a substantially conical shape that closes the liquid agent passage 11 c, and has a through hole 24 a through which water passes in the center. . At both ends of the through hole 24a, a pair of adjustment grooves 24b and 24c are formed in the circumferential direction of the valve body 24 from the through hole 24a.
The adjustment groove 24b on the inlet side, that is, the water tank side, extends to a range of approximately 90 degrees with respect to the direction of the through hole 24a, and is formed with a constant width and depth over the entire range.
The adjustment groove 24c on the outlet side, that is, the main flow path side, is extended to a range of about 90 degrees with respect to the direction of the through hole 24a, symmetrically with the adjustment groove 24b on the upstream side. Has been.
　また、この弁体２４の一方の端部には、操作用つまみ２５を組み付ける筒状の取付部２４ｄを設け、取付部２４ｄの内周には雌ネジを形成し、操作用つまみ２５の雄ネジ（図示せず）と螺合する。
　操作用つまみ２５は、図９に示すように液剤混合噴射器２３の外部に露出し、つまみ部２５ａを突設しているため、指で摘んで回動させることで、弁体２４を回動させることができる。 In addition, a cylindrical mounting portion 24d for assembling the operation knob 25 is provided at one end of the valve body 24, a female screw is formed on the inner periphery of the mounting portion 24d, and the male screw of the operation knob 25 is provided. Screwed (not shown).
As shown in FIG. 9, the operation knob 25 is exposed to the outside of the liquid mixture injector 23 and has a knob portion 25 a so that the valve body 24 is rotated by picking it with a finger and rotating it. Can be made.
　このような液剤流路弁を設けたことにより、第二実施形態の液剤混合噴射器２３では、一定量の水を噴射しているときに、操作用つまみ２５を回動させて弁体２４の貫通孔２４ａを液剤流路１１ｃに合致させると、第二の液体が弁体２４において最も広く短い貫通孔２４ａのみを通過する。
　このため、流路抵抗が小さくなり、比較的多量の第二の液体が主流路５に導入され、噴射される混合水の濃度が大きくなる。 By providing such a liquid agent flow path valve, in the liquid agent mixing injector 23 of the second embodiment, the operation knob 25 is rotated to inject the valve body 24 when a certain amount of water is being injected. When the through hole 24 a is matched with the liquid agent flow passage 11 c, the second liquid passes through only the widest and short through hole 24 a in the valve body 24.
For this reason, the channel resistance is reduced, a relatively large amount of the second liquid is introduced into the main channel 5, and the concentration of the mixed water to be ejected is increased.
　また、噴射水量を一定に保持したまま、操作用つまみ２５を回動させて弁体２４の調整溝２４ｂ、２４ｃを液剤流路１１ｃに合致させると、第二の液体が入口側の調整溝２４ｂ、貫通孔２４ａ、および出口側の調整溝２４ｃにかけて長い流路を通過する。このため、流路抵抗が大きくなり、比較的少量の第二の液体が主流路５に導入され、噴射される混合水の濃度が小さくなる。
　貫通孔２４ａから遠ざかるほど出口側の調整溝２４ｃが狭く形成されているため、貫通孔２４ａと液剤流路１１ｃが合致する位置から大きく回動するに連れて、流路断面積が小さくなり、流路抵抗が大きくなって混合水の濃度が低下する。 Further, when the operation knob 25 is rotated while keeping the amount of jetted water constant, the adjustment grooves 24b and 24c of the valve body 24 are matched with the liquid agent flow passage 11c, and the second liquid becomes the adjustment groove 24b on the inlet side. , The through hole 24a and the adjustment groove 24c on the outlet side pass through a long flow path. For this reason, the flow path resistance increases, a relatively small amount of the second liquid is introduced into the main flow path 5, and the concentration of the mixed water to be ejected decreases.
Since the adjustment groove 24c on the outlet side is formed narrower as the distance from the through hole 24a increases, the cross-sectional area of the flow path becomes smaller as the through hole 24a and the liquid agent flow path 11c are largely rotated from the position where they match, The road resistance increases and the concentration of the mixed water decreases.
　さらに操作用つまみ２５を回動させて、弁体２４の貫通孔２４ａおよび調整溝２４ｂ、２４ｃのいずれもが液剤流路１１ｃに合致しない位置にすると、弁体２４によって液剤流路１１ｃが閉鎖され、第二の液体が主流路５に供給されず、第二の液体を含まない水が噴射される。
　このように、液剤流路弁によって液剤流路１１ｃを開閉することができ、さらに、主流路５に導入される第二の液体の量を調整することもできる。
　なお、上記で示した液剤流路弁の構成に代えて、例えば、電源を用いて液剤の流量を制御できる電気的液剤流路弁とすることもでき、また、上記で示した液剤流路弁と電気的液剤流路弁を並設することもできる。電気的液剤流路弁を設ける場合は、液剤流路又は主流路の液剤流路よりも下流側に、液剤流路の濃度を測定できる濃度センサーを配設し、その濃度センサーからの液剤の濃度データを利用して電気的液在流路弁における液剤の流量を調節するのが好ましい。 Further, when the operation knob 25 is rotated so that neither the through hole 24a of the valve body 24 nor the adjustment grooves 24b, 24c match the liquid agent flow path 11c, the liquid agent flow path 11c is closed by the valve body 24. The second liquid is not supplied to the main flow path 5, and water that does not contain the second liquid is jetted.
Thus, the liquid agent flow path 11c can be opened and closed by the liquid agent flow path valve, and the amount of the second liquid introduced into the main flow path 5 can be adjusted.
In addition, instead of the configuration of the liquid agent passage valve shown above, for example, an electric liquid agent passage valve that can control the flow rate of the liquid agent using a power source can be used, and the liquid agent passage valve shown above And an electric liquid passage valve can be provided side by side. When an electric liquid agent flow path valve is provided, a concentration sensor capable of measuring the concentration of the liquid agent flow path is disposed downstream of the liquid agent flow path or the main liquid solution flow path, and the concentration of the liquid agent from the concentration sensor is provided. It is preferable that the flow rate of the liquid agent in the electrical liquid passage valve is adjusted using the data.
　さらに、第二実施形態では、図１０に示すように、液剤流路１１ｃと主流路５との合流部近傍に、負圧を発生させて第二の液体の導入を促す負圧発生部を設けている。
　この負圧発生部は、主流路の一部を内管２６と外管２７とからなる二重管構造に形成するとともに、外管２７に液剤流路１１ｃとの合流部を設けてなる。 Furthermore, in the second embodiment, as shown in FIG. 10, a negative pressure generating unit that generates a negative pressure and promotes the introduction of the second liquid is provided in the vicinity of the junction of the liquid agent channel 11 c and the main channel 5. ing.
This negative pressure generating part is formed by forming a part of the main flow path into a double-pipe structure composed of an inner pipe 26 and an outer pipe 27, and providing the outer pipe 27 with a junction with the liquid agent flow path 11c.
　内管２６の先端部分は縮径され、細い口径となって外管２７内に開口している。管の断面積が小さくなると流速が速くなるため、内管２６を通過した水は高速で外管２７内に放出される。
　この高速の水に押されて外管２７の水の流速も速められるが、これに応じて断面積の大きい外管２７の内部では圧力が低下する。このため、液剤流路１１ｃと主流路５との合流部近傍には負圧が発生して、第二の液体を主流路５側へ牽引する力が働く。 The distal end portion of the inner tube 26 is reduced in diameter so as to have a narrow diameter and open into the outer tube 27. As the cross-sectional area of the tube decreases, the flow velocity increases, so that water that has passed through the inner tube 26 is discharged into the outer tube 27 at a high speed.
Although pushed by this high-speed water, the flow rate of the water in the outer tube 27 is also increased, but the pressure is reduced inside the outer tube 27 having a large cross-sectional area accordingly. For this reason, a negative pressure is generated in the vicinity of the joining portion between the liquid agent channel 11 c and the main channel 5, and a force that pulls the second liquid toward the main channel 5 side acts.
　これにより、第二実施形態の液剤混合噴射器２３では、水タンク１５に供給される水が空気を介して液剤タンク１０の第二の液体を加圧するのに加え、負圧発生部の負圧によって第二の液体が牽引されるので、より確実に第二の液体を主流路５に導入し、水と混合することができる。
　また、主流路５の通水量に増減があった場合には、第一実施形態と同様に、分岐流路１３、水タンク１５、空気流路１７、液剤タンク１０および液剤流路１１ｃからなる調整機構によって、第二の液体の導入量を追従させて混合水の濃度を一定に保持することができるが、この調整機構では空気を介在させているため、空気が緩衝材となってしまい調整に時間を要することがある。しかし、負圧発生部を設けることにより、主流路５の通水量の増減に伴い、負圧発生部の負圧が即時に増減するため、第二の液体の導入量を即時に追従させることができる。 Thereby, in the liquid agent mixing injector 23 of the second embodiment, in addition to the water supplied to the water tank 15 pressurizing the second liquid in the liquid agent tank 10 via air, the negative pressure of the negative pressure generating unit Since the second liquid is pulled by the second liquid, the second liquid can be more reliably introduced into the main flow path 5 and mixed with water.
Further, when there is an increase or decrease in the water flow rate of the main flow path 5, as in the first embodiment, the adjustment comprising the branch flow path 13, the water tank 15, the air flow path 17, the liquid agent tank 10, and the liquid agent flow path 11c. The mechanism can keep the concentration of the mixed water constant by following the amount of the second liquid introduced.However, since this adjustment mechanism uses air, the air becomes a buffering material, making adjustments. It may take time. However, by providing the negative pressure generating part, the negative pressure of the negative pressure generating part increases or decreases immediately with the increase or decrease of the water flow rate of the main flow path 5, so that the introduction amount of the second liquid can be immediately followed. it can.
　＜第三実施形態＞

The upper part of the tube is connected to a liquid agent flow path provided in the flow path branching member 30 and communicates with the main flow path 5.
　液剤混合噴射器２８には、図２０に点線矢印で示した空気流路１７が形成される。
　液剤タンク蓋部材２９は、蓋部との間に間隙を保持するとともに、この間隙と水タンク１５とを連通させる孔２９ａ、この間隙と液剤タンク１０とを連通させる孔２９ｂを形成しており（図２１参照）、この間隙が水タンク１５と液剤タンク１０とを通気させる空気流路１７となる。 In the liquid mixture injector 28, an air flow path 17 shown by a dotted arrow in FIG. 20 is formed.
The liquid agent tank lid member 29 holds a gap between the lid part and a hole 29a for communicating the gap with the water tank 15 and a hole 29b for communicating the gap and the liquid agent tank 10 ( 21), this gap becomes an air flow path 17 through which the water tank 15 and the liquid agent tank 10 are vented.
　また、第三実施形態の液剤混合噴射器２８にも、水位感知弁が設けられている。
　図１９、図２０、図２１に示すように、この水位感知弁は、フロート上部材とフロート下部材とからなり全体として中空の環状に形成されたフロート部材３１と、このフロート部材３１の上面に戴置された幅広のパッキン部材３２とからなる。
　この水位感知弁は、液剤タンク蓋部材２９から垂下された液剤タンク１０との螺合部を包囲するように装着されて、水タンク１５内部の水位が所定高さ以上に上昇すると、フロート部材３１が浮き上がることでパッキン部材３２が空気流路１７の入口の孔２９ａを閉塞し、水が空気流路１７および液剤タンク１０に混入することを防止することができる。
　パッキン部材３２は、空気流路を閉塞する基部と、この基部からフロート部材３１側へ突出したいくつかの突起部とを備えており、この突起部をフロート上部材の上面に設けられたいくつかの凹部に挿入することにより、フロート部材３１に位置決めされている。本実施形態では、上記基部を断面が方形の環状に形成しており、また、上記突起部及び凹部を円柱状に形成している。なお、パッキン部材の全体又は上記突起部のみを弾性部材より形成するとともにフロート部材の凹部を突起部よりも小さく形成し、この突起部を弾性変形させて凹部に挿入することで、突起部と凹部とを強固に嵌め合わせるのが好ましい。なお、この弾性変形を利用した嵌め合わせに代えて、または併用して、突起部と凹部とを接着剤で接着する等の方法を用いてもよい。
　パッキン部材３２は、Ｏリング１８、１９と同様に、加硫ゴム（ＮＢＲ、ＥＰＤＭ、フッ素系ゴム、シリコン系ゴム等）またはエラストマー製のものを用いるのが好ましく、密閉性や耐変形性の観点から特に加硫ゴムが好ましい。 The liquid level mixing valve 28 of the third embodiment is also provided with a water level detection valve.

As a result, the packing member 32 closes the inlet hole 29 a of the air flow path 17, and water can be prevented from being mixed into the air flow path 17 and the liquid agent tank 10.
The packing member 32 includes a base portion that closes the air flow path, and several protrusions that protrude from the base portion toward the float member 31, and these protrusions are provided on the upper surface of the float upper member. The float member 31 is positioned by being inserted into the recess.

　第三実施形態の液剤混合噴射器２８において、噴射器本体８、流量制御弁９、液剤流路弁、負圧発生部などの他の構成は、第二実施形態と同様である。
　第三実施形態の液剤混合噴射器２８では、水タンク１５内部に液剤タンク１０を設けたことにより、第一実施形態および第二実施形態に比して、外観上簡素な構成にすることができる。
　また、使用により水タンク１５の水が増加するとともに液剤タンク１０の第二の液体が減少しても、液剤混合噴射器２８の重心が比較的移動しないため、使用性が向上する。
　なお、第三実施形態から水位感知弁、液剤流路弁、及び負圧発生部のうち、全部あるいは１つ以上を無くした構成とすることも可能であり、これらも本発明の実施形態として有効なものである。 In the liquid agent mixing injector 28 of the third embodiment, other configurations such as the injector main body 8, the flow rate control valve 9, the liquid agent flow path valve, and the negative pressure generating unit are the same as those of the second embodiment.
In the liquid agent mixing injector 28 of the third embodiment, by providing the liquid agent tank 10 inside the water tank 15, it is possible to make the structure simple in appearance as compared with the first embodiment and the second embodiment. .

In addition, it is also possible to have a configuration in which all or one or more of the water level sensing valve, the liquid agent flow path valve, and the negative pressure generating unit are eliminated from the third embodiment, and these are also effective as an embodiment of the present invention. Is something.
　＜第四実施形態＞
　第一実施形態から第三実施形態の液剤混合噴射器では、気密の水タンク１５と気密の液剤タンク１０とを空気流路１７によって通気させ、水タンク１５に水が供給されることで空気を液剤タンク１０に流入させ、第二の液体を主流路５側に加圧していたが、第四実施形態の液剤混合噴射器３３は、液剤タンク１０の全部または一部を水タンク１５の内部に配置して、水タンク１５内部の水圧により液剤タンク１０を変形させて第二の液体を主流路５側に加圧することを特徴とする。 <Fourth embodiment>
In the liquid agent mixing injectors of the first to third embodiments, the airtight water tank 15 and the airtight liquid agent tank 10 are vented by the air flow path 17, and water is supplied to the water tank 15 to supply air. Although the second liquid was flowed into the liquid agent tank 10 and pressurized to the main flow path 5 side, the liquid agent mixing / injecting device 33 according to the fourth embodiment placed all or part of the liquid agent tank 10 inside the water tank 15. It arrange | positions and deform | transforms the liquid agent tank 10 with the water pressure inside the water tank 15, and pressurizes the 2nd liquid to the main flow path 5 side, It is characterized by the above-mentioned.
　図２２に示すように、第四実施形態の液剤混合噴射器３３は、基端部から噴射口へ水が流れる主流路５を形成している点、流量制御弁９を設けている点は、第三実施形態と同様である。
　また、主流路５からは分岐する分岐流路１３の終端に水タンク１５が設けられている点、水タンク１５内に液剤タンク１０が設けられ、第二の液体を液剤タンク１０から主流路５へ導入する液剤流路が形成されている点も第三実施形態と同様であり、外観上はほぼ第三実施形態と異ならない。 As shown in FIG. 22, the liquid agent mixing injector 33 of the fourth embodiment has a main flow path 5 through which water flows from the base end to the injection port, and a flow control valve 9 is provided. The same as in the third embodiment.
Further, a water tank 15 is provided at the end of the branch flow path 13 branched from the main flow path 5, a liquid agent tank 10 is provided in the water tank 15, and the second liquid is supplied from the liquid agent tank 10 to the main flow path 5. The point that the liquid agent flow channel to be introduced is formed is the same as that of the third embodiment, and the appearance is almost the same as that of the third embodiment.
　図２２に示すように、第四実施形態では、第三実施形態と異なり、液剤タンク蓋部材２９に空気流路を設けていないため、水タンク１５内部と液剤タンク１０内部との間で空気の行き来が起こらないようになっている。
　他方、液剤タンク１０は、液剤タンク蓋部材２９との螺合部を除き、軟質材料で形成されており、水が主流路５から水タンク１５に流れ込むにつれて液剤タンク１０に水圧がかかり変形させる。これにより、第二の液体が液剤流路を経て主流路５に導入され、水に混合される。 As shown in FIG. 22, in the fourth embodiment, unlike the third embodiment, no air flow path is provided in the liquid agent tank lid member 29, so that air is not generated between the water tank 15 and the liquid agent tank 10. There is no going back and forth.
On the other hand, the liquid agent tank 10 is made of a soft material except for a screwed portion with the liquid agent tank lid member 29, and the liquid agent tank 10 is deformed by water pressure as water flows from the main flow path 5 into the water tank 15. Thereby, a 2nd liquid is introduce | transduced into the main flow path 5 through a liquid agent flow path, and is mixed with water.
　なお、液剤タンク１０の全部が水タンク１５の内部に収容されている必要はなく、軟質材料で形成され変形可能な一部分（変形可能部）が水タンク１５内部に配置されていればよい。
　第四実施形態の液剤混合噴射器３３に用いる第二の液体は、水よりも密度の小さいものを用いるのが好ましい。
　また、流量制御弁９、液剤流路弁、負圧発生部のうち、いずれか１つあるいは２つ以上を組み合わせて第四実施形態に付加することもでき、これらも本発明の実施形態として有効なものである。 The liquid agent tank 10 does not have to be accommodated inside the water tank 15, and a deformable part (deformable portion) formed of a soft material may be disposed inside the water tank 15.
As the second liquid used in the liquid agent mixing injector 33 of the fourth embodiment, it is preferable to use a liquid having a density lower than that of water.
In addition, any one or two or more of the flow rate control valve 9, the liquid agent flow path valve, and the negative pressure generating unit can be added to the fourth embodiment, and these are also effective as the embodiment of the present invention. It is a thing.
　第四実施形態の液剤混合噴射器３３では、水タンク１５内部に、軟質材料からなる液剤タンク１０を配置したことにより、流量制御弁９を開くと、主流路５を通過する水の一部が分岐流路１３に分岐して水タンク１５内部の水量が増加するにつれて、液剤タンク１０に水圧がかかり内側に変形する。これにより、液剤タンク１０の容積が減少するため、自動的に第二の液体が主流路５に導入され、水に第二の液体を混合して噴射することができる。 In the liquid agent mixing injector 33 of the fourth embodiment, since the liquid agent tank 10 made of a soft material is disposed inside the water tank 15, when the flow control valve 9 is opened, a part of the water passing through the main flow path 5 is obtained. As the amount of water inside the water tank 15 increases by branching to the branch flow path 13, water pressure is applied to the liquid agent tank 10 and the liquid tank 10 is deformed inward. Thereby, since the volume of the liquid agent tank 10 decreases, the second liquid is automatically introduced into the main flow path 5, and the second liquid can be mixed and injected into water.
　第四実施形態の第一変形例として、図２３に示すように、液剤タンク１０の全部または一部を軟質材料で形成するのではなく、液剤タンク１０の外壁の一部を、液剤タンク１０の他の部分に対して内側に往復摺動可能な栓部材３４からなる変形可能部として形成してもよい。
　この変形可能部は、たとえば図２３に示すように、略筒状に形成した液剤タンク１０本体に対して、底板にあたる栓部材３４が上下にスライドできるように水密に取り付けられている。 As a first modification of the fourth embodiment, as shown in FIG. 23, all or part of the liquid agent tank 10 is not formed of a soft material, but a part of the outer wall of the liquid agent tank 10 is You may form as a deformable part which consists of the plug member 34 which can be slid back and forth inside with respect to another part.
For example, as shown in FIG. 23, the deformable portion is watertightly attached to the main body of the liquid agent tank 10 formed in a substantially cylindrical shape so that the plug member 34 corresponding to the bottom plate can slide up and down.
　この第一変形例では、このような液剤タンク１０の変形可能部が水タンク１５内部に配置されていることにより、流量制御弁９を開くと、主流路５を通過する水の一部が分岐流路１３に分岐して水タンク１５内部の水量が増加するにつれて、栓部材３４に水圧がかかり内側（上側）に変形する。これにより、液剤タンク１０の容積が減少するため、自動的に第二の液体が主流路５に導入され、水に第二の液体を混合して噴射することができる。 In the first modified example, since the deformable portion of the liquid agent tank 10 is arranged inside the water tank 15, when the flow control valve 9 is opened, a part of the water passing through the main flow path 5 is branched. As the amount of water in the water tank 15 increases by branching to the flow path 13, water pressure is applied to the plug member 34 and the inner side (upper side) is deformed. Thereby, since the volume of the liquid agent tank 10 decreases, the second liquid is automatically introduced into the main flow path 5, and the second liquid can be mixed and injected into water.
　また、第四実施形態の第二変形例として、図２８に示すように、液剤タンク１０を蛇腹状に形成してもよい。
　この第二変形例の液剤混合噴射器３３では、水タンク１５内部に、蛇腹状の液剤タンク１０を配置したことにより、流量制御弁９を開くと、主流路５を通過する水の一部が分岐流路１３に分岐して水タンク１５内部の水量が増加するにつれて、蛇腹状の液剤タンク１０に水圧がかかり、蛇腹を縮める方向に変形させる。
　これにより、蛇腹状の液剤タンク１０の容積が減少するため、自動的に第二の液体が主流路５に導入され、水に第二の液体を混合して噴射することができる。 As a second modification of the fourth embodiment, the liquid agent tank 10 may be formed in a bellows shape as shown in FIG.
In the liquid agent mixing injector 33 of the second modification example, the bellows-like liquid agent tank 10 is disposed inside the water tank 15, so that when the flow control valve 9 is opened, a part of the water passing through the main flow path 5 is obtained. As the amount of water inside the water tank 15 increases by branching to the branch flow path 13, water pressure is applied to the bellows-shaped liquid agent tank 10 and the bellows is deformed in a contracting direction.
Thereby, since the volume of the bellows-like liquid agent tank 10 is reduced, the second liquid is automatically introduced into the main flow path 5, and the second liquid can be mixed and ejected into water.
　この第二変形例において、液剤流路には液剤流路延長部材１２が接続されて、液剤タンク１０の底部付近まで延長されている。この液剤流路延長部材１２は、液剤流路に接続する位置である上方の初端位置から液剤タンク１０の底部付近に位置する終端位置まで到達する垂直方向長さＬを有し、垂直方向長さＬが蛇腹状液剤タンク１０の伸び縮みに応じて変化できる長さ可変液剤流路延長部材１２とするのがよい。たとえば、図２８に示すような弾性を有する螺旋状に形成するのがよい。 In this second modified example, the liquid agent passage extension member 12 is connected to the liquid agent passage and extends to the vicinity of the bottom of the liquid agent tank 10. The liquid agent channel extension member 12 has a vertical length L that reaches from the upper initial end position, which is a position connected to the liquid agent channel, to a terminal position located near the bottom of the liquid agent tank 10. It is preferable that the length L of the fluid flow path extending member 12 is such that the length L can be changed according to the expansion and contraction of the bellows-shaped liquid tank 10. For example, it is preferable to form a spiral having elasticity as shown in FIG.
　この第二変形例では、使用時に蛇腹状の液剤タンク１０の底面が上昇し、第二の液体の液面があまり低下しないため、液剤流路延長部材１２の垂直方向長さＬを必ずしも液剤タンク１０の底部に到達する長さとしなくてもよい。
　しかし、第二の液体の使用量が少なく、当初より第二の液体の液面が低いこともありうるため、第二の液体を確実に吸い上げるために、Ｌを液剤タンク１０の底部付近まで到達する長さとすることが好ましい。 In this second modification, the bottom surface of the bellows-shaped liquid agent tank 10 rises during use, and the liquid level of the second liquid does not decrease so much. Therefore, the vertical length L of the liquid agent flow path extending member 12 is not necessarily limited to the liquid agent tank. It does not have to be the length to reach the bottom of the ten.
However, since the amount of the second liquid used is small and the liquid level of the second liquid may be low from the beginning, L reaches the vicinity of the bottom of the liquid agent tank 10 to surely suck up the second liquid. It is preferable to set it to a length.
　なお、この液剤流路延長部材１２としては管状部材を使用でき、管状部材の材料としてはポリマー樹脂部材若しくは加硫ゴム等の弾性材料を使用でき、塩化ビニル樹脂からなるホース部材が特に好適である。
　このように、液剤流路と液剤流路延長部材１２とによって、第二の液体を安定的に主流路に導入することができる。 In addition, a tubular member can be used as the liquid agent channel extending member 12, and an elastic material such as a polymer resin member or vulcanized rubber can be used as the material of the tubular member, and a hose member made of vinyl chloride resin is particularly suitable. .
As described above, the second liquid can be stably introduced into the main flow path by the liquid flow path and the liquid flow path extending member 12.
　上記の第四実施形態およびその第一変形例、第二変形例においては、水タンク１５に水が流入して水タンク１５内の空気の圧縮が起こり、それに応じて内圧が上昇して一定の強さに達した後に液剤タンク１０を変形させ容積を減少させる。そのため、水タンク１５内の空気が多いほど、分岐流路１３からの水の流入と液剤タンク１０の変形（主流路５への第二の液体の供給）との間に時間差が生じやすくなる。
　よって、使用開始時における水タンク１５内の空気の量を減らし、水の量を増加させるほど、分岐流路１３からの水の流入と主流路５への第二の液体の供給との前記時間差が生じにくくなる。
　そのため、使用開始時の水タンク１５内の空気の量を減らし、水の量を増やすことが好ましい。望ましくは、水タンク１５に水を充填した状態で、水タンク１５を蓋部３０ａに装着し、実質的に水のみが入っている状態とするのがよい。 In the fourth embodiment and the first and second modifications thereof, water flows into the water tank 15 and the air in the water tank 15 is compressed, and the internal pressure rises accordingly and is constant. After reaching the strength, the liquid agent tank 10 is deformed to reduce the volume. Therefore, as the air in the water tank 15 increases, a time difference is more likely to occur between the inflow of water from the branch flow path 13 and the deformation of the liquid agent tank 10 (supply of the second liquid to the main flow path 5).
Therefore, as the amount of air in the water tank 15 at the start of use is reduced and the amount of water is increased, the time difference between the inflow of water from the branch channel 13 and the supply of the second liquid to the main channel 5 is increased. Is less likely to occur.
Therefore, it is preferable to reduce the amount of air in the water tank 15 at the start of use and increase the amount of water. Desirably, with the water tank 15 filled with water, the water tank 15 is mounted on the lid 30a so that only water is substantially contained.
　また、水タンク１５には、内部と外部との通気を開閉する通気開閉弁を設けるのが良い。この通気開閉弁は、水が流入する液剤タンク１０周囲の内部空間の上部に設けるのがよく、好ましくは内部空間の上面を区画する部位に設けるのがよい。流量制御弁９を開いて水を水タンク１５に流入させるときに、通気開閉弁を開いて空気を水タンク１５の外部に排出し、内部空間の空気が減った状態、好ましくは、内部空間が水のみで充満した状態で開閉弁を閉じて使用すればよい。 Also, the water tank 15 is preferably provided with a ventilation opening / closing valve that opens and closes ventilation between the inside and the outside. This vent on / off valve is preferably provided in the upper part of the internal space around the liquid agent tank 10 into which water flows, and is preferably provided in a site that divides the upper surface of the internal space. When the flow control valve 9 is opened and water is allowed to flow into the water tank 15, the vent on / off valve is opened to discharge the air to the outside of the water tank 15, and the air in the internal space is reduced. The on-off valve may be closed and used in a state filled with water only.
　なお、第四実施形態及び変形例から、液剤流路弁及び／又は負圧発生部を無くすことも可能であり、これらも本発明の実施形態として有効なものである。 In addition, it is possible to eliminate a liquid agent flow path valve and / or a negative pressure generating part from the fourth embodiment and the modified examples, and these are also effective as an embodiment of the present invention.

　第五実施形態の液剤混合噴射器３５では、噴射器本体８の外部かつ上流の主流路５´に、水タンク１５、液剤タンク１０等を設けたことにより、高い位置に所持して取り回すことの多い噴射器本体８を軽量化することができて液剤混合噴射器３５の使用性が向上するとともに、図２４のように、使用者が持たない水タンク１５および液剤タンク１０を大容量に形成することができて、長時間継続して多くの混合水を噴射することができる。 In the liquid agent mixing injector 35 of the fifth embodiment, the water channel 15, the liquid agent tank 10, and the like are provided in the main flow path 5 ′ outside and upstream of the injector body 8, so that the liquid agent mixing injector 35 is held at a high position. The injector body 8 having a large amount can be reduced in weight, and the usability of the liquid agent mixing injector 35 can be improved, and the water tank 15 and the liquid agent tank 10 that the user does not have are formed in a large capacity as shown in FIG. It is possible to spray a large amount of mixed water continuously for a long time.
　第五実施形態においては、図２４、図２５に示すように、噴射器本体８と、水タンク１５及び液剤タンク１０を備える容器本体６０とを備え、この容器本体６０と噴射器本体８との間に連結ホース部６１を配するのがよい。
　また、この連結ホース部６１は、弾性変形（折れ曲がり）可能な弾性連結ホース部とするのがよい。 In the fifth embodiment, as shown in FIGS. 24 and 25, the injector body 8 and the container body 60 including the water tank 15 and the liquid agent tank 10 are provided, and the container body 60 and the injector body 8 are It is preferable to arrange the connecting hose portion 61 between them.
The connecting hose portion 61 is preferably an elastic connecting hose portion that can be elastically deformed (bent).
　この弾性連結ホース部６１の長さを長くすることにより、容器本体を地面等の上に設置した状態で、噴射器本体８を自由に取り回しながら噴射作業を行うことができる。
　よって、弾性連結ホース部６１の長さは３０ｃｍ以上とするのがよく、さらに５０ｃｍ以上、特に７０ｃｍ以上とするのがよい。 By increasing the length of the elastic connecting hose portion 61, it is possible to perform an injection operation while freely manipulating the injector main body 8 in a state where the container main body is installed on the ground or the like.
Therefore, the length of the elastic connecting hose portion 61 is preferably 30 cm or more, more preferably 50 cm or more, and particularly preferably 70 cm or more.
　なお、連結ホース部６１の長さが長すぎると、コスト上昇や重量増加を招くので、２００ｃｍ以下とするのがよく、さらに１５０ｃｍ以下とするのがよく、特に１２０ｃｍ以下とするのがよい。 It should be noted that if the length of the connecting hose portion 61 is too long, it causes an increase in cost and an increase in weight. Therefore, it is preferably 200 cm or less, more preferably 150 cm or less, and particularly preferably 120 cm or less.
　なお、噴射器本体８と容器本体６０との間に、弾性連結ホース部６１を巻きつけるホールリール等、長さ調節可能な部材（図示せず）を配する構成としてもよい。
　また、容器本体６０は必ずしも噴射器本体８と併用される必要はなく、単体でも技術的に有用であり、先端に水を放出できる何らかの機構を取り付けるなどして、液剤の混合噴射に用いることができる。 In addition, it is good also as a structure which arrange | positions members (not shown) which can adjust length, such as a hole reel which winds the elastic connection hose part 61, between the injector main body 8 and the container main body 60.
In addition, the container body 60 is not necessarily used together with the injector body 8, and it is technically useful by itself, and can be used for mixing and injecting liquid agents by attaching some mechanism capable of discharging water to the tip. it can.
　なお、弾性連結ホース部６１が水圧により変形して容積が変化する度合が大きいと、その容積の変化によって第二の液体の混合率にむらが起こりやすくなるので、合成樹脂や金属などからなる繊維やコードで補強した変形率の小さい弾性連結ホース部６１を用いるのが好ましい。 If the elastic connecting hose portion 61 is deformed by water pressure and the volume is changed to a large extent, the change in volume tends to cause unevenness in the mixing ratio of the second liquid. It is preferable to use an elastic connection hose portion 61 reinforced with a cord and having a small deformation rate.
　このように弾性連結ホース部６１を設けることにより、容器本体６０（液剤タンク１０および水タンク１５）を大きくしても噴射作業を行いやすくすることができる。液剤タンク１０を大きくできれば、第二の液剤の補充なく長時間の混合噴射が可能となる。また、水タンク１５を大きくできれば水タンク１５から液剤タンク１０への流入する空気の総量を増やすことができ、液剤タンク１０内の液剤の残存を無くす、又は残存量を少なくすることができる。 By providing the elastic connecting hose portion 61 in this way, it is possible to facilitate the injection work even if the container body 60 (the liquid agent tank 10 and the water tank 15) is enlarged. If the liquid tank 10 can be enlarged, it is possible to perform mixed injection for a long time without replenishment of the second liquid. Further, if the water tank 15 can be enlarged, the total amount of air flowing from the water tank 15 into the liquid agent tank 10 can be increased, and the remaining liquid agent in the liquid agent tank 10 can be eliminated or the remaining amount can be reduced.
　第五実施形態においては、主流路５´の容器本体より下流側に流量制御弁９を設けることにより、噴射を止めたときに、流量制御弁９より上流側の水圧は、給水設備の水圧（水道水圧）に維持される。よって、流量制御弁９を再度開いて噴射を再開したときに、既に主流路５´と水タンク１５内との水圧はほぼ同等になっているので、すぐに安定した混合率を得ることができる。
　なお、その流量制御弁９は、流路の開閉のみでなく流量の大小も調節できるようにしてもよい。また、好ましくは流量制御弁９を噴射器本体８に設けるのがよく、第五実施形態では、第一実施形態と同様の流量制御弁９を噴射器本体８に設けている。 In the fifth embodiment, when the injection is stopped by providing the flow rate control valve 9 on the downstream side of the main body of the main flow path 5 ', the water pressure on the upstream side of the flow rate control valve 9 is the water pressure ( Maintained at tap water pressure). Therefore, when the flow rate control valve 9 is opened again and the injection is resumed, the water pressure in the main flow path 5 'and the water tank 15 is already substantially equal, so that a stable mixing ratio can be obtained immediately. .
The flow rate control valve 9 may be capable of adjusting not only the opening / closing of the flow path but also the flow rate. In addition, the flow control valve 9 is preferably provided in the injector main body 8, and in the fifth embodiment, the flow control valve 9 similar to that in the first embodiment is provided in the injector main body 8.
　第五実施形態においては、連結ホース部６１、または容器本体６０の主流路５´に液剤流路３６が合流する位置の下流側に、流路を開閉できる弁を設けることもできる。
　また、主流路５´から分岐流路１３が分岐する位置の上流側に、流路を開閉できる弁を設けることもできる。
　このような流路開閉用の弁を付加することにより、各部材の取り外しや取付作業時における作業性を向上させるとともに、使用者の意図によらずに噴射してしまうのを防止することができる。 In 5th embodiment, the valve which can open and close a flow path can also be provided in the downstream of the position where the liquid agent flow path 36 merges with the main flow path 5 'of the connection hose part 61 or the container main body 60.
Further, a valve capable of opening and closing the flow path can be provided upstream of the position where the branch flow path 13 branches from the main flow path 5 ′.
By adding such a valve for opening and closing the flow path, it is possible to improve workability at the time of removing and attaching each member, and to prevent injection without intention of the user. .
　なお、連結ホース部６１か、容器本体６０の主流路５´に液剤流路３６が合流する位置の下流側か、主流路５´から分岐流路が分岐する位置の上流側かのいずれかに、流量の大小を調整できる機構を設けてもよいが、コスト上昇を防止するため、流量調整機構は噴射器本体８のみに設けるのが好ましい。 In addition, either the connecting hose portion 61, the downstream side of the position where the liquid agent flow path 36 joins the main flow path 5 ′ of the container body 60, or the upstream side of the position where the branch flow path branches from the main flow path 5 ′. Although a mechanism capable of adjusting the magnitude of the flow rate may be provided, the flow rate adjusting mechanism is preferably provided only in the injector body 8 in order to prevent an increase in cost.
　第五実施形態においては、図２９に示すように、地面等への設置した際の安定性を高めるために、水タンク１５の下部に設置用部位６２を設けるのがよい。
　この設置用部位６２は水タンク１５に一体に設けても、別体として水タンク１５に取りつけてもよい。 In the fifth embodiment, as shown in FIG. 29, in order to enhance the stability when installed on the ground or the like, it is preferable to provide an installation site 62 in the lower part of the water tank 15.
The installation part 62 may be provided integrally with the water tank 15 or may be separately attached to the water tank 15.
　設置用部位６２は、容器本体６０を地面等の平面状の箇所に置いたときに倒れない形態であればよい。好ましくは、容器本体６０の安定性をより高めるため、水タンク１５を水平面に設置したときに、水タンク１５全体を水平面に投影した水タンク１５の投影輪郭線Ｐよりも、設置用部位６２が水平面に接触している範囲の輪郭線Ｏが外側に位置するのがよい。
　設置用部位６２の輪郭線Ｏのうち、水タンク１５の投影輪郭線Ｐの外側に位置する部分の長さＯ１＋Ｏ２＋Ｏ３＋Ｏ４は、水タンク１５の投影輪郭線Ｐの周の長さの一部であればよいが、好ましくは投影輪郭線Ｐの周の長さの１／２以上とするのがよく、さらに好ましくは投影輪郭線Ｐの周の長さの３／４以上とするのがよく、特に好ましくは輪郭線Ｏの全体が投影輪郭線Ｐの外側に位置する（投影輪郭線Ｐが輪郭線Ｏに囲まれている）のがよい。 The installation part 62 may be in a form that does not fall down when the container body 60 is placed on a flat part such as the ground. Preferably, in order to further improve the stability of the container body 60, when the water tank 15 is installed on a horizontal plane, the installation site 62 is more than the projected contour line P of the water tank 15 in which the entire water tank 15 is projected on the horizontal plane. The contour line O in a range in contact with the horizontal plane is preferably located outside.
The length O1 + O2 + O3 + O4 of the contour line O of the installation part 62 located outside the projected contour line P of the water tank 15 is a part of the circumference of the projected contour line P of the water tank 15. Preferably, it should be ½ or more of the circumference of the projection contour P, more preferably 3/4 or more of the circumference of the projection contour P, and particularly preferably. It is preferable that the entire contour line O is located outside the projected contour line P (the projected contour line P is surrounded by the contour line O).
　＜第六実施形態＞
　第五実施形態では、第二の液体を収容する液剤タンク１０と水タンク１５とを通気させる空気流路１７を設け、液剤タンク１０から主流路５´へ第二の液体を導入する液剤流路３６を設けていた。
　第六実施形態の液剤混合噴射器は、これに代えて、第四実施形態のように、液剤タンク１０の全部または一部を水タンク１５の内部に配置して、水タンク１５内部の水圧により液剤タンク１０を変形させて第二の液体を主流路５´側に加圧することを特徴とする。 <Sixth embodiment>
In the fifth embodiment, an air flow path 17 is provided to ventilate the liquid tank 10 containing the second liquid and the water tank 15, and the liquid flow path for introducing the second liquid from the liquid tank 10 to the main flow path 5 '. 36 was provided.
Instead of this, in the liquid agent mixing injector of the sixth embodiment, all or part of the liquid agent tank 10 is disposed inside the water tank 15 as in the fourth embodiment, and the water pressure inside the water tank 15 is increased. The liquid agent tank 10 is deformed to pressurize the second liquid toward the main flow path 5 '.
　例えば、図３０に示すように、液剤タンク１０を軟質材料で形成し、その変形可能な一部分（変形可能部）を水タンク１５の内部に配置することができる。
　他の例として、図３１に示すように、液剤タンク１０の外壁の一部を、液剤タンク１０の他の部分に対して内側に往復摺動可能な栓部材３４からなる変形可能部として形成し、これを水タンク１５の内部に配置することができる。
　さらに他の例として、図３２に示すように、蛇腹状の液剤タンク１０を水タンク１５の内部に配置することができる。 For example, as shown in FIG. 30, the liquid agent tank 10 can be formed of a soft material, and a deformable portion (deformable portion) can be disposed inside the water tank 15.
As another example, as shown in FIG. 31, a part of the outer wall of the liquid agent tank 10 is formed as a deformable portion including a plug member 34 that can reciprocate inward with respect to the other part of the liquid agent tank 10. This can be placed inside the water tank 15.
As yet another example, as shown in FIG. 32, a bellows-shaped liquid agent tank 10 can be disposed inside the water tank 15.
　また、第六実施形態のそれぞれの例で、螺旋状等の長さ可変液剤流路延長部材１２（図３２参照）の構成も採用することができる。
　その他の構成は、第五実施形態と同様であり、変形（折れ曲がり）可能な連結ホース部６１を設けたり、噴射器本体８と容器本体６０の間にホールリール等の長さ調節可能な部材を配したり、流量制御弁９、液剤流路弁、負圧発生部等を設けてもよい。 Further, in each example of the sixth embodiment, a configuration of the length-variable liquid agent flow path extending member 12 (see FIG. 32) having a spiral shape or the like can also be adopted.
Other configurations are the same as in the fifth embodiment, and a connecting hose portion 61 that can be deformed (bent) is provided, or a length-adjustable member such as a hall reel is provided between the injector body 8 and the container body 60. Or a flow rate control valve 9, a liquid agent flow path valve, a negative pressure generating unit, and the like may be provided.
　第六実施形態では、主流路５´から水タンク１５に流入する水の水圧により液剤タンク１０を内側に変形させ、第二の液体を主流路５に供給することができる。
　さらに、噴射器本体８の外部かつ上流に液剤タンク１０等を配置したことにより、液剤タンク１０を大容量化しても、噴射器本体８による噴射作業を行いやすくすることができる。 In the sixth embodiment, the liquid agent tank 10 can be deformed inward by the water pressure of water flowing into the water tank 15 from the main channel 5 ′, and the second liquid can be supplied to the main channel 5.
Furthermore, by arranging the liquid agent tank 10 and the like outside and upstream of the injector main body 8, even if the liquid agent tank 10 is increased in capacity, it is possible to facilitate the injection work by the injector main body 8.
　＜その他の変形例＞
　その他の変形例として、図２６に示すように、噴射器本体８に二種以上の噴射口を設けるとともに、二以上の噴射形状を切り換える噴射切換弁を設けてもよい。
　二種以上の噴射口としては、一例として、水を一本の直線状に噴射するストレート噴射口５０と、シャワー状に噴射するシャワー噴射口５１との組み合わせを用いることができる。 <Other variations>
As another modified example, as shown in FIG. 26, two or more types of injection ports may be provided in the injector body 8, and an injection switching valve that switches between two or more injection shapes may be provided.
As an example of the two or more types of injection ports, a combination of a straight injection port 50 that injects water into a single straight line and a shower injection port 51 that injects water in a shower shape can be used.
　噴射切換弁の例として、図２６に示すように、主流路５の先端を閉鎖するとともに、主流路５の側面に水抜け孔５２を設ける。
　噴射器本体８の先端には、噴射切換弁５３が螺進により前後動自在に取り付けられる。噴射切換弁５３は、先端にシャワー噴射口５１を形成するとともにその中央には開口が形成されており、シャワー噴射口５１と開口との間は仕切り５４で区画されている。 As an example of the injection switching valve, as shown in FIG. 26, the front end of the main flow path 5 is closed and a water drain hole 52 is provided on the side surface of the main flow path 5.
An injection switching valve 53 is attached to the tip of the injector body 8 so as to be movable back and forth by screwing. The injection switching valve 53 has a shower injection port 51 formed at the tip thereof and an opening formed at the center thereof, and a partition 54 is defined between the shower injection port 51 and the opening.
　噴射切換弁５３が水抜け孔５２（噴射器本体８）に対して前後動することにより、図２６（ａ）に示すストレート噴射と、図２６（ｂ）に示すシャワー噴射とを切り換えることができる。
　ストレート噴射状態では、水が、図２６（ａ）の矢印に示すように、主流路５、水抜け孔５２から仕切り５４の内側の中央空間５５に流出し、噴射器本体８の先端に設けられたストレート流路５６を経てストレート噴射口５０から噴射される。
　シャワー噴射状態では、水が、図２６（ｂ）の矢印に示すように、主流路５、水抜け孔５２から間仕切り５４の外側のシャワー流路５７に流出し、シャワー噴射口５１から噴射される。
　その他の構成は、第一実施形態と同様とする。 When the injection switching valve 53 moves back and forth with respect to the water drain hole 52 (injector body 8), the straight injection shown in FIG. 26 (a) and the shower injection shown in FIG. 26 (b) can be switched. .
In the straight injection state, water flows out from the main flow path 5 and the water drain hole 52 into the central space 55 inside the partition 54 and is provided at the tip of the injector body 8 as shown by the arrow in FIG. Injected from the straight injection port 50 through the straight flow path 56.
In the shower injection state, water flows out from the main flow path 5 and the water drain hole 52 to the shower flow path 57 outside the partition 54 and is injected from the shower injection port 51 as shown by the arrow in FIG. .
Other configurations are the same as those in the first embodiment.
　噴射切換弁を設けた液剤混合噴射器では、噴射形状を切り換える際に水の噴射量が変化するため、主流路内の水圧に変化を生じる。
　このような水圧の変化に応じて、水タンク１５へ流入する水の圧力が変化し、液剤タンク１０の第二の液体を圧す力を追従させるため、第一実施形態から第六実施形態の構成は、特に噴射切換弁を有する液剤混合噴射器に好適である。 In the liquid agent mixed injector provided with the injection switching valve, the water injection amount changes when the injection shape is switched, so that the water pressure in the main flow path changes.
According to such a change in the water pressure, the pressure of the water flowing into the water tank 15 changes and the force for pressing the second liquid in the liquid agent tank 10 is followed. Is particularly suitable for a liquid mixture injector having an injection switching valve.
　さらに、その他の変形例として、図２７のように、液剤流路４１内に主流路５から液剤タンク１０への水または第二の液体の逆流を防止する逆流防止弁を設けてもよい。
　この逆流防止弁は、液剤流路４１中に設けられた弁座３７と、この弁座３７の下流側（主流路側）に配置される球形弁体３８と、バネ台座３９に当接して球形弁体３８を下流側から弁座へ付勢するコイルスプリング４０とからなる。 Furthermore, as another modified example, as shown in FIG. 27, a backflow prevention valve for preventing the backflow of water or the second liquid from the main flow path 5 to the liquid tank 10 may be provided in the liquid flow path 41.
The backflow prevention valve is in contact with a valve seat 37 provided in the liquid agent passage 41, a spherical valve body 38 disposed on the downstream side (main flow passage side) of the valve seat 37, and a spring pedestal 39. The coil spring 40 urges the body 38 from the downstream side to the valve seat.
　逆流防止弁を設けた液剤混合噴射器では、流量制御弁９を開くと、主流路５から水タンク１５へ分岐する水によって液剤タンク１０の第二の液体が加圧され、コイルスプリング４０の付勢力に反して球形弁体３８を弁座３７から離間させ、第二の液体が主流路５へ導入される。
　一方、噴射形状の切り換えなど何らかの原因により主流路５内の水圧が一時的に上昇し、液剤流路４１を液剤タンク１０側へ逆流する水または第二の液体の流れが発生した場合には、逆流する水等の水圧およびコイルスプリング４０の付勢力によって球形弁体３８が弁座３７に押し付けられ、液剤流路４１が閉塞されるため、逆流が防止される。
　球形弁体３８が金属製または金属球の周囲を熱可塑性エラストマー等で被覆したものなど、十分に重い場合には、コイルスプリング４０を無くしても逆流防止弁としての役割を果たすことができる。 In the liquid agent mixing injector provided with the backflow prevention valve, when the flow control valve 9 is opened, the second liquid in the liquid agent tank 10 is pressurized by the water branched from the main flow path 5 to the water tank 15, and the coil spring 40 is attached. The spherical valve body 38 is separated from the valve seat 37 against the force, and the second liquid is introduced into the main flow path 5.
On the other hand, when the water pressure in the main flow path 5 temporarily rises for some reason, such as switching of the injection shape, and the flow of water or the second liquid that flows back to the liquid agent tank 10 side occurs, The spherical valve body 38 is pressed against the valve seat 37 by the water pressure such as water that flows backward and the urging force of the coil spring 40, and the liquid agent passage 41 is closed, so that backflow is prevented.
If the spherical valve body 38 is sufficiently heavy, such as a metal or a metal sphere coated with a thermoplastic elastomer or the like, it can serve as a backflow prevention valve without the coil spring 40.
　これにより、主流路５から液剤タンク１０への水または第二の液体を防止することができるため、液剤タンク１０内の第二の液体の濃度を一定に保つことができ、噴射される混合水の濃度も一定に保つことができる。 Thereby, since water or the second liquid from the main flow path 5 to the liquid agent tank 10 can be prevented, the concentration of the second liquid in the liquid agent tank 10 can be kept constant, and the mixed water to be injected The concentration of can also be kept constant.
　本発明の第二実施形態、第三実施形態、および第五実施形態では、水タンク１５から液剤タンク１０へとつながる空気流路１７を設け、この空気流路１７に水位感知弁を設けたことにより、水タンク１５に貯蔵された水の量によって水位感知弁が空気流路１７を閉鎖することができる。
　しかし、さらに、液剤混合噴射器が大きく傾いた場合に、空気流路１７を閉止して、水タンク１５に貯蔵された水が液剤タンク１０に流入してしまうのを防ぐ傾斜時閉止機構を付加するのがよい。 In the second embodiment, the third embodiment, and the fifth embodiment of the present invention, an air flow path 17 connected from the water tank 15 to the liquid agent tank 10 is provided, and a water level detection valve is provided in the air flow path 17. Thus, the water level detection valve can close the air flow path 17 according to the amount of water stored in the water tank 15.
However, in addition, when the liquid agent mixing injector is greatly inclined, the air flow path 17 is closed, and a tilting closing mechanism is added to prevent water stored in the water tank 15 from flowing into the liquid agent tank 10. It is good to do.
　傾斜時閉止機構の一例としては、水位感知弁の開閉に伴ってフロート部材が周囲の他部材と接触摩擦する面である水位感知弁接触面、および／またはその他部材がフロート部材と接触摩擦する部分である他部材接触面を低摩擦係数の材料で形成するか、水位感知弁接触面および／または他部材接触面を低摩擦係数の材料でコーティングしたりするのがよい。
　低摩擦係数の材料としては、フッ素樹脂やテフロン（登録商標）等のポリテトラフルオロエチレン樹脂を使用するのがよい。 As an example of the closing mechanism at the time of tilting, the water level sensing valve contact surface, which is a surface where the float member comes into contact friction with other surrounding members as the water level sensing valve opens and closes, and / or a portion where other members come into contact friction with the float member The other member contact surface may be formed of a material having a low friction coefficient, or the water level sensing valve contact surface and / or the other member contact surface may be coated with a material having a low friction coefficient.
As a material having a low friction coefficient, it is preferable to use a polytetrafluoroethylene resin such as fluororesin or Teflon (registered trademark).
　このような低摩擦係数の材料を用いることにより、水位感知弁接触面および／または他部材接触面の摩擦力が低下するため、液剤混合噴射器が大きく傾いて、フロート部材の移動方向が、浮力のかかる真上方向から逸れた場合でも、フロート部材が容易に摺動して空気流路１７を閉止することができる。 By using such a material having a low coefficient of friction, the frictional force of the water level sensing valve contact surface and / or the contact surface of the other member is reduced, so that the liquid mixture injector is greatly inclined and the movement direction of the float member is buoyant. Even when it deviates from such an upward direction, the float member can slide easily and the air flow path 17 can be closed.
　また、傾斜時閉止機構の別の例として、液剤混合噴射器が傾いて、水タンク１５内の水が水位感知弁に達した時にも、水位感知弁が真上方向以外の斜め方向にも作動して、水位感知弁が空気流路１７を閉止できるようにしてもよい。
　たとえば、第一実施形態のフロート保持部材２２を図１１のような円筒状ではなく逆さ円錐状に形成して、フロート部材２０を収納する空間が、下部から上部に行くに従って広がる形態にする構成が挙げられる。
　なお、この場合、液剤混合噴射器が傾いていない状態において水タンクに水が溜まって水が水位感知弁に達したときに、フロート部材２０が上方に移動して、その移動により空気流路を閉止する機能も合わせて有するようにする。 Further, as another example of the closing mechanism at the time of tilting, when the liquid mixture injector is tilted and the water in the water tank 15 reaches the water level detection valve, the water level detection valve also operates in an oblique direction other than directly above. Then, the water level sensing valve may be able to close the air flow path 17.
For example, the float holding member 22 of the first embodiment is formed in an inverted conical shape instead of a cylindrical shape as shown in FIG. 11 so that the space for storing the float member 20 expands from the lower part to the upper part. Can be mentioned.
In this case, when the liquid mixture injector is not tilted, when water accumulates in the water tank and the water reaches the water level detection valve, the float member 20 moves upward, and the movement causes the air flow path to flow. It also has a function of closing.
　また、傾斜時閉止機構のさらに別の例として、水位感知弁とは別体に、傾斜感知弁のフロート部材を設けるようにしてもよい。液剤混合噴射器が傾いて、水タンク１５内の水が傾斜感知弁に達した時に、傾斜感知弁のフロート部材が移動して、傾斜感知弁が空気流路１７を閉止する。
　この構成における傾斜感知弁の移動方向は、真上方向に対して４５度～９０度とするのがよく、さらに６０～９０度とするのが良い。
　この場合、液剤混合噴射器が傾いていない状態において水タンクに水が溜まって水が水位感知弁に達したときに、フロート部材水位感知弁が上方に移動して、その移動により水位感知弁が空気流路を閉止する機能も合わせて有するようにする。 Further, as another example of the closing mechanism at the time of tilting, a float member of the tilt sensing valve may be provided separately from the water level sensing valve. When the liquid mixture injector is inclined and the water in the water tank 15 reaches the inclination detection valve, the inclination detection valve float member moves, and the inclination detection valve closes the air flow path 17.
The moving direction of the tilt sensing valve in this configuration is preferably 45 to 90 degrees with respect to the upward direction, and more preferably 60 to 90 degrees.
In this case, when water is accumulated in the water tank and the water reaches the water level sensing valve when the liquid mixture injector is not tilted, the float member water level sensing valve moves upward, and the water level sensing valve is moved by the movement. It also has a function of closing the air flow path.
　なお、上述の記載において「水が水位感知弁（傾斜感知弁）に達したとき」とは、水位感知弁（傾斜感知弁）のフロート部材の少なくとも一部に水が達したとき、水位感知弁（傾斜感知弁）のフロート部材の全体に水が達したとき、又は水位感知弁（傾斜感知弁）のフロート部材の全体が水面以下となったとき、のいずれも含む。 In the above description, “when water reaches the water level sensing valve (tilt sensing valve)” means that when water reaches at least a part of the float member of the water level sensing valve (tilt sensing valve). This includes both when water reaches the entire float member of the (tilt sensing valve) or when the entire float member of the water level sensing valve (tilt sensing valve) falls below the water surface.
　上記の水位感知弁、傾斜感知弁は、水と各フロート部材との密度差を利用して空気流路１７の閉止（開閉）を行うものであり、言い換えると、フロート部材が水との密度差により移動して、その移動により空気流路を開閉する開閉機構である。上記に示した形態以外でも、水とフロート部材との密度差により移動して、その移動により空気流路１７を開閉する構造を水位感知弁または傾斜感知弁として使用することができる。 The water level detection valve and the inclination detection valve perform the closing (opening / closing) of the air flow path 17 using the density difference between water and each float member. In other words, the float member has a density difference with water. And an opening / closing mechanism that opens and closes the air flow path by the movement. In addition to the forms shown above, a structure that moves due to the density difference between water and the float member and opens and closes the air flow path 17 by the movement can be used as the water level detection valve or the inclination detection valve.
　上記のような水とフロート部材との密度差により作動して、空気流路を開閉する開閉機構に代えて、水タンク１５から液剤タンク１０への水の混入を防止するために、空気を通すが水を通さない空気流通・水非流通機構を空気流路１７に配設してもよい。
　たとえば、空気流路１７中に、空気は通すが水は通さない膜を張設することができる。
　また、空気流路１７の一部の断面積を小さくして、空気は通過できるが水はその表面張力によって通過できない細空気流路部を形成してもよい。
　さらに、センサーを使用して空気流路１７への水の浸入を感知し、空気流路を開閉する電気式弁を設けてもよい。 Instead of the opening / closing mechanism that opens and closes the air flow path by operating due to the density difference between the water and the float member as described above, air is allowed to pass from the water tank 15 to the liquid agent tank 10. An air flow / water non-flow mechanism that does not allow water to pass through may be disposed in the air flow path 17.
For example, a film that allows air to pass but not water can be stretched in the air flow path 17.
Alternatively, a partial cross-sectional area of the air flow path 17 may be reduced to form a fine air flow path portion that allows air to pass but does not allow water to pass by its surface tension.
In addition, an electric valve that opens and closes the air flow path by sensing the entry of water into the air flow path 17 using a sensor may be provided.
　また、第二実施形態、第三実施形態、第四実施形態、第五実施形態、第六実施形態および上述のいずれの変形例においても、第一実施形態と同様の分岐流路延長部材６３、及び／又はその他の第一実施形態に示された構成や材質を付加又は適用することができ、これにより第一実施形態の場合と同様の効果が発生する。 Further, in the second embodiment, the third embodiment, the fourth embodiment, the fifth embodiment, the sixth embodiment, and any of the above-described modifications, the branch flow path extending member 63 similar to the first embodiment, And / or the structure and material shown in other 1st embodiment can be added or applied, and the effect similar to the case of 1st embodiment generate | occur | produces by this.
　液剤タンク１０中の容積である液剤容積Ｖ１（水タンク１５内に液剤タンク１０を収容し液剤タンク１０の容積が変化する例では、自然状態での液剤タンク１０の最大容積）が小さすぎると、液剤タンク１０への第二の液体の補充（または、第二の液体を補充済みの液剤タンク１０への交換）の頻度が多くなってしまう。
　そのため、液剤容積Ｖ１を１００ｃｃ以上とするのが好ましく、２００ｃｃ以上とするのがさらに好ましく、４００ｃｃ以上とするが特に好ましい。特に第二の液体の収容量を重視する場合には、Ｖ１を７００ｃｃ以上とするのがよい。 If the liquid volume V1 that is the volume in the liquid tank 10 (the maximum volume of the liquid tank 10 in the natural state in the example in which the liquid tank 10 is accommodated in the water tank 15 and the volume of the liquid tank 10 changes) is too small, The frequency of replenishment of the second liquid to the liquid agent tank 10 (or replacement with the liquid agent tank 10 that has been replenished with the second liquid) increases.
Therefore, the liquid agent volume V1 is preferably 100 cc or more, more preferably 200 cc or more, and particularly preferably 400 cc or more. In particular, when importance is placed on the amount of the second liquid, V1 should be 700 cc or more.
　また、液剤容積Ｖ１が大きすぎると、液剤混合噴射器の大型化および重量増加により取り扱い性が悪化する。
　そのため、Ｖ１を２０００ｃｃ以下とするのが好ましく、１５００ｃｃ以下とするのがさらに好ましく、１０００ｃｃ以下とするのが特に好ましい。特に、取り扱い性を重視する場合には、Ｖ１を５００ｃｃ以下とするのが良い。 On the other hand, when the liquid agent volume V1 is too large, the handleability deteriorates due to an increase in size and weight of the liquid agent mixing injector.
Therefore, V1 is preferably 2000 cc or less, more preferably 1500 cc or less, and particularly preferably 1000 cc or less. In particular, when importance is attached to handling properties, V1 is preferably set to 500 cc or less.
　水タンク１５中で水を収容する空間の容積である水容積Ｖ２（水タンク１５内に液剤タンク１０を収容して液剤タンク１０の容積を変化させる例では、水タンク１５の総容積から、水タンク１５に収容される液剤タンク１０の一部を引いた体積）は以下のようにするのが好ましい。 Water volume V2 that is the volume of the space in which water is stored in the water tank 15 (in the example in which the liquid agent tank 10 is accommodated in the water tank 15 and the volume of the liquid agent tank 10 is changed, the water volume 15 The volume obtained by subtracting a part of the liquid agent tank 10 accommodated in the tank 15 is preferably as follows.
　水タンク１５と液剤タンク１０とを空気流路１７で繋いで空気を流通させる第一実施形態等では、使用開始時に大気圧の空気を圧縮して液剤タンク１５に送るので、水容積Ｖ２を液剤容積Ｖ１より大きくするのがよい。具体的にはＶ２／Ｖ１を、１．５以上とするのが好ましく、２以上とするのがさらに好ましく、５以上とするのが特に好ましい。
　また、Ｖ２／Ｖ１を大きくしすぎると、Ｖ２が大きくなって液剤混合噴射器の大型化および重量増加により取り扱い性が悪化したり、Ｖ１が小さくなって前述の問題が生じる。そのため、Ｖ２／Ｖ１は、３０以下とするのが好ましく、２０以下とするのがさらに好ましく、１０以下とするのが特に好ましい。 In the first embodiment in which the water tank 15 and the liquid agent tank 10 are connected by the air flow path 17 and the air is circulated, atmospheric pressure air is compressed and sent to the liquid agent tank 15 at the start of use. It is better to make it larger than the volume V1. Specifically, V2 / V1 is preferably 1.5 or more, more preferably 2 or more, and particularly preferably 5 or more.
On the other hand, if V2 / V1 is too large, V2 becomes large and the handling property deteriorates due to the increase in size and weight of the liquid mixture injector, and V1 becomes small, resulting in the above-mentioned problems. Therefore, V2 / V1 is preferably 30 or less, more preferably 20 or less, and particularly preferably 10 or less.
　水タンク１５に液剤タンク１０を収容する第四実施形態等では、水容積Ｖ２が小さいほうが、水タンク１５へ水が流入したときに時間差なく液剤タンク１０を加圧することができ、第二の液体の混合率を安定させることができる。そのため、Ｖ２／Ｖ１は、１．０以下にするのが好ましく、０．５以下とするのがさらに好ましく、０．２以下とするのが特に好ましい。
　なお、Ｖ２が小さすぎると、液剤タンク１０外面と水タンク１５内面との間に遊びがなくなり、液剤混合噴射器の組み立て作業中に両者が接触して組み立てが困難になる。また、分岐流路１３から水タンク１５内へ水が流入しにくくなる。そのため、Ｖ２／Ｖ１を、０．０１以上とするのが好ましく、０．０５以上とするのがさらに好ましく、０．１以上とするのが特に好ましい。 In the fourth embodiment or the like in which the liquid tank 10 is accommodated in the water tank 15, the smaller the water volume V2 can pressurize the liquid tank 10 without time difference when water flows into the water tank 15, and the second liquid The mixing ratio can be stabilized. Therefore, V2 / V1 is preferably 1.0 or less, more preferably 0.5 or less, and particularly preferably 0.2 or less.
If V2 is too small, there is no play between the outer surface of the liquid agent tank 10 and the inner surface of the water tank 15, and both come into contact during the assembly operation of the liquid agent mixing injector, making assembly difficult. Further, it becomes difficult for water to flow into the water tank 15 from the branch channel 13. Therefore, V2 / V1 is preferably 0.01 or more, more preferably 0.05 or more, and particularly preferably 0.1 or more.
　なお、本発明において、給水設備から液剤混合噴射器に供給され、第二の液体を混合される「水」としては、水道水、井戸水、浄化処理をされた水、池や川などの水源からそのまま流入した水などを使用可能であり、また、それらに第二の液体以外の液剤などを含む水であってもよい。
　たとえば、あらかじめ液肥を混合した水を給水設備から液剤混合噴射器の主流路に供給し、第二の液体として農薬をこの水に混合することができる。また、あらかじめ第一の液肥を混合した水を給水設備から供給し、第二の液体として第二の液肥をこの水に混合することも可能である。 In the present invention, the “water” supplied from the water supply facility to the liquid mixture injector and mixed with the second liquid includes tap water, well water, purified water, ponds, rivers, and other water sources. Water that has just flowed in can be used, and water that contains a liquid agent other than the second liquid can also be used.
For example, water in which liquid fertilizer is mixed in advance can be supplied from the water supply facility to the main flow path of the liquid mixture injector, and the agrochemical can be mixed into this water as the second liquid. It is also possible to supply water mixed with the first liquid fertilizer in advance from the water supply facility and mix the second liquid fertilizer with this water as the second liquid.
