Description

本発明は、水，溶液や灯油等の液体容器の口部から挿入し、液体容器内の液体を移送先容器へ移送する液体ポンプに関するものである。 The present invention relates to a liquid pump that is inserted from the mouth of a liquid container such as water, solution, or kerosene, and transfers the liquid in the liquid container to a transfer destination container.

従来より、灯油等を入れた液体容器から灯油ストーブのタンク等の移送先容器へ灯油等の液体を移送して小分けするために、液体ポンプが用いられている。このような液体ポンプとしては、例えば、（特許文献１）や（特許文献２）に開示されたものが知られている。
実用新案登録第３０９４６７６号公報実用新案登録第３０９７７５７号公報 Conventionally, a liquid pump has been used in order to transfer a liquid such as kerosene from a liquid container containing kerosene or the like to a transfer destination container such as a tank of a kerosene stove.

Utility Model Registration No. 3094676 Utility Model Registration No. 3097757

しかしながら上記従来の技術においては、以下のような課題を有していた。
（１）（特許文献１）や（特許文献２）に開示された液体ポンプは、移送先容器に液体を送る注液ホースの長さが、液体容器の内部に挿入する吸液管の長さと同じか吸液管よりも長いため、液体を移送し終えた際に注液ホース内に液体が残留し易いという課題を有していた。そのため、注液ホースの先端部を移送先容器の口部から外した際に、注液ホース内に残留した液体が注液ホースの先端部より吐出され、床を汚す等の問題が生じていた。
（２）吸液管と注液ホースを合わせた全長が長くなるため、液体を移送する際、液体が液体ポンプ内を通過する時間が長くなり、その結果、液体を移送するのに要する時間が長くなるという課題を有していた。
（３）液体を移送する際、移送先容器に移送された液体に注液ホースの先端部が浸かり、容器の液面より移送先容器の液面が低い場合は、ポンプを停止させても、サイホン現象により容器内の液体が移送先容器に続々と移送されてしまい、移送先容器の口部から液体を溢れさせてしまうことがある。吸油管又は注油ホースに空気を導入すればサイホン現象を防止できるため、液体ポンプの吸液管の上端部に液体戻し溝を設け、吸油管で吸い上げた液体の一定量を液体戻し溝から容器内に戻している。このため、移送先容器に移送される液体の流量は、液体戻し溝から容器内に戻される液体の流量分だけ減少しており、流量損失が生じているという課題を有していた。
（４）注液ホースの長さが液体容器の内部に挿入する吸液管の長さと同じか吸液管よりも長いため、液体ポンプを保管する際には注液ホースが嵩張り、コンパクトに保管できないという課題を有していた。 However, the above conventional techniques have the following problems.
(1) In the liquid pump disclosed in (Patent Document 1) and (Patent Document 2), the length of the liquid injection hose that sends the liquid to the transfer destination container is the length of the liquid suction pipe inserted into the liquid container. Since it is the same or longer than the liquid suction pipe, there is a problem that the liquid tends to remain in the liquid injection hose when the liquid has been transferred. Therefore, when the tip of the injection hose was removed from the mouth of the transfer destination container, the liquid remaining in the injection hose was discharged from the tip of the injection hose, causing problems such as soiling the floor. .
(2) Since the total length of the liquid suction pipe and the liquid injection hose becomes long, when the liquid is transferred, the time for the liquid to pass through the liquid pump becomes long, and as a result, the time required to transfer the liquid It had the problem of becoming longer.
(3) When transferring the liquid, if the tip of the injection hose is immersed in the liquid transferred to the transfer destination container, and the liquid level of the transfer destination container is lower than the liquid level of the container, even if the pump is stopped, Due to the siphon phenomenon, the liquid in the container may be transferred to the transfer destination container one after another, and the liquid may overflow from the mouth of the transfer destination container. Since siphon phenomenon can be prevented by introducing air into the oil absorption pipe or oil supply hose, a liquid return groove is provided at the upper end of the liquid absorption pipe of the liquid pump, and a certain amount of liquid sucked up by the oil absorption pipe is put into the container from the liquid return groove. It has returned to. For this reason, the flow rate of the liquid transferred to the transfer destination container is reduced by the flow rate of the liquid returned from the liquid return groove into the container, and there is a problem that a flow rate loss occurs.
(4) Since the length of the liquid injection hose is equal to or longer than the liquid absorption pipe inserted into the liquid container, the liquid injection hose is bulky and compact when storing the liquid pump. It had the problem that it could not be stored.

本発明は上記従来の課題を解決するもので、移送させる液体の流量を増加させることができるため液体の移送時間を短縮でき、また液体を移送し終えて注液ホースの先端部を移送先容器の口部から外した際、液体が注液ホースの先端部より吐出されることがなく床を汚す等の問題が生じず、さらにホースが嵩張ることなくコンパクトに保管できる液体ポンプを提供することを目的とする。 The present invention solves the above-described conventional problems, and can increase the flow rate of the liquid to be transferred, so that the liquid transfer time can be shortened, and the end of the liquid injection hose is moved to the destination container after the liquid has been transferred. To provide a liquid pump that can be stored in a compact manner without causing the hose to be bulky, without causing liquid to be discharged from the tip of the injection hose and causing the floor to become dirty. Objective.

上記従来の課題を解決するために本発明の液体ポンプは、以下の構成を有している。
本発明の請求項１に記載の液体ポンプは、電池が内蔵される本体と、前記本体の下部に延設され液体容器の口部から前記液体容器の内部に挿入される吸液管と、前記吸液管と連通し前記本体に延設され前記吸液管よりも短い長さに形成された注液ホースと、を備えた構成を有している。
この構成により、以下のような作用が得られる。
（１）注液ホースが吸液管よりも短いので、液体を移送し終えた際に注液ホース内の液体をほぼ残らず移送先容器に移送させることができる。また、注液ホースの内表面積を小さくできるため、移送された液体が注液ホースの内面に付着する量も減らすことができる。そのため、注液ホースの先端部を移送先容器の口部から外した際に、注液ホースの先端部より吐出される液体の量が極めて少なく、床を汚す等の問題が生じ難い。
（２）吸液管と注液ホースを合わせた全長を短くできるため、液体を移送する際、液体が液体ポンプ内を通過する時間を短縮でき、その結果、液体を移送するのに要する時間を短縮できる。
（３）注液ホースが吸液管よりも短いので、注液ホースが嵩張ることなく液体ポンプをコンパクトに保管できる。
（４）注液ホースが短いので、注液ホースの原料コストを削減することができるとともに省資源性に優れる。
（５）注液ホースが吸液管よりも短いので、液体を移送する際、移送先容器に移送された液体に注液ホースの先端部が浸かることがないため、吸油管で吸い上げた液体の一定量を液体戻し溝から容器内に戻さなくてもサイホン現象を防止できる。液体戻し溝から液体を容器内に戻すような流量損失がないため、従来の流量損失分を上乗せして流量を増加させることができる。 In order to solve the above conventional problems, the liquid pump of the present invention has the following configuration.
The liquid pump according to claim 1 of the present invention includes a main body in which a battery is built, a liquid absorption pipe that extends from a lower portion of the main body and is inserted into the liquid container through a mouth portion of the liquid container, A liquid injection hose that communicates with the liquid absorption pipe and extends to the main body and has a shorter length than the liquid absorption pipe.
With this configuration, the following effects can be obtained.
(1) Since the liquid injection hose is shorter than the liquid absorption pipe, almost no liquid in the liquid injection hose can be transferred to the transfer destination container when the liquid has been transferred. Moreover, since the inner surface area of the injection hose can be reduced, the amount of the transferred liquid that adheres to the inner surface of the injection hose can also be reduced. For this reason, when the tip of the liquid injection hose is removed from the mouth of the transfer destination container, the amount of liquid discharged from the tip of the liquid injection hose is extremely small, and problems such as soiling the floor are unlikely to occur.
(2) Since the total length of the liquid suction pipe and the liquid injection hose can be shortened, when transferring the liquid, the time for the liquid to pass through the liquid pump can be shortened. As a result, the time required for transferring the liquid can be reduced. Can be shortened.
(3) Since the liquid injection hose is shorter than the liquid absorption pipe, the liquid pump can be stored compactly without the liquid injection hose being bulky.
(4) Since the injection hose is short, the raw material cost of the injection hose can be reduced and the resource saving property is excellent.
(5) Since the liquid injection hose is shorter than the liquid absorption pipe, when the liquid is transferred, the tip of the liquid injection hose is not immersed in the liquid transferred to the transfer destination container. The siphon phenomenon can be prevented without returning a certain amount from the liquid return groove into the container. Since there is no flow loss that returns the liquid from the liquid return groove into the container, the flow rate can be increased by adding the conventional flow loss.

注液ホースと吸液管の内径は適宜選択して設定できるが、注液ホースの内径が吸液管の内径よりも大きいものが好ましい。注液ホースを移送される液体の流量を増やし、液体を移送するのに要する時間を短縮させることができるからである。また、注液ホース先端部に液面センサを設けた場合は、液体ポンプ内（吸液管に内設されたポンプ装置）で形成された気泡が注液ホース先端部付近の液面を覆うと、液面センサの動作が泡に邪魔されて不安定になることがある。最悪の場合は、液面を検知しなくなることもある。しかし、注液ホースの内径を大きくすることにより、注液ホース内の流速が遅くなり、気泡を消すことができるため、液面センサの動作の安定性を高めることができる。 The inner diameters of the liquid injection hose and the liquid suction pipe can be selected and set as appropriate, but the liquid injection hose preferably has an inner diameter larger than that of the liquid suction pipe. This is because the flow rate of the liquid transferred through the liquid injection hose can be increased, and the time required to transfer the liquid can be shortened. Also, when a liquid level sensor is provided at the tip of the liquid injection hose, if bubbles formed in the liquid pump (pump device installed in the liquid suction pipe) cover the liquid level near the liquid injection hose tip. The operation of the liquid level sensor may be disturbed by bubbles and become unstable. In the worst case, the liquid level may not be detected. However, by increasing the inner diameter of the liquid injection hose, the flow rate in the liquid injection hose becomes slow and the bubbles can be eliminated, so that the stability of the operation of the liquid level sensor can be improved.

本発明の請求項２に記載の発明は、請求項１に記載の液体ポンプであって、前記吸液管と前記注液ホースが一体成形された構成を有している。
この構成により、請求項１で得られる作用に加え、以下のような作用が得られる。
（１）吸液管と注液ホースが一体成形されているので、吸液管と注液ホースを別々に成形し、本体を介して吸液管と注液ホースが連通するように組み立てるという製造工程が不要なため、生産性に優れる。
（２）吸液管と注液ホースが一体成形されているので、吸液管や注液ホースの接合箇所から液漏れが生じる等の不具合が生じることがなく、また製品得率も高めることができる。 Invention of Claim 2 of this invention is a liquid pump of Claim 1, Comprising: It has the structure by which the said liquid absorption pipe | tube and the said liquid injection hose were integrally molded.
With this configuration, in addition to the operation obtained in the first aspect, the following operation can be obtained.
(1) Since the liquid absorption pipe and the liquid injection hose are integrally formed, the liquid absorption pipe and the liquid injection hose are separately formed and assembled so that the liquid absorption pipe and the liquid injection hose communicate with each other through the main body. Since no process is required, productivity is excellent.
(2) Since the liquid absorption pipe and the liquid injection hose are integrally molded, there is no problem such as liquid leakage from the joint between the liquid absorption pipe and liquid injection hose, and the product yield can be increased. it can.

ここで、吸液管と注液ホースは、ポリエチレン、ポリプロピレン、塩化ビニル樹脂、ポリエチレンテレフタレート等の種々の合成樹脂を用いて一体成形することができる。
一般的に、注液ホースは可撓性が要求され、吸液管は剛性が要求されるが、注液ホースや吸液管の肉厚を調整したりリブを設けたりすることで、可撓性や剛性を要求通りにすることができる。 Here, the liquid absorption pipe and the liquid injection hose can be integrally formed using various synthetic resins such as polyethylene, polypropylene, vinyl chloride resin, polyethylene terephthalate.
In general, the liquid injection hose is required to be flexible, and the liquid absorption pipe is required to be rigid. However, by adjusting the wall thickness of the liquid injection hose and liquid absorption pipe or providing ribs, the liquid injection hose can be flexible. Property and rigidity can be achieved as required.

吸液管の下端部は膨出状に形成することができる。吸液管の下端部にポンプ装置を収納するためである。
また、吸液管の上部には孔部を有する配線引出部を形成する。吸液管の下端部に収納されたポンプ装置と本体とを接続するポンプ用配線を吸液管の外に引き出すためである。配線引出部からポンプ用配線を引き出した後、配線引出部の孔部とポンプ用配線との隙間をパッキンやシーリング材等の封止部材で密閉する。液漏れを防止するためである。また、配線引出部は本体で隠蔽される箇所に形成するのが好ましい。ポンプ用配線を吸液管及び本体に内蔵して、見栄えを良くするとともに断線し難くするためである。 The lower end portion of the liquid absorption pipe can be formed in a bulging shape. This is because the pump device is accommodated in the lower end portion of the liquid absorption pipe.
A wiring lead portion having a hole is formed in the upper portion of the liquid absorption pipe. This is because the wiring for the pump connecting the pump device housed in the lower end portion of the liquid absorption pipe and the main body is drawn out of the liquid absorption pipe. After the pump wiring is drawn out from the wiring lead-out part, the gap between the hole of the wiring lead-out part and the pump wiring is sealed with a sealing member such as packing or a sealing material. This is to prevent liquid leakage. Moreover, it is preferable that the wiring lead-out portion is formed at a location hidden by the main body. This is because the wiring for the pump is built in the liquid absorption pipe and the main body to improve the appearance and make it difficult to disconnect.

First, the pump device storage 4 is formed at the lower end, the liquid suction pipe 3 is formed with the tube side latching portion 10, the wiring lead-out portion 11, and the bellows portion 12 on the upper side, and the hose side latching portion 13 and the bellows. The injection hose 6 having the portions 8 and 9 and the injection hose tip 7 formed at the tip is integrally formed.
Next, the pump wiring 18 is inserted into the liquid suction pipe 3 from the wiring lead-out portion 11, and the end of the pump wiring 18 is pulled out from the pump device housing portion 4. Next, the pump device 17 is connected to the pump wiring 18 drawn out from the pump device storage portion 4, and after the pump device 17 is stored in the pump device storage portion 4, the cap 5 is attached. After adjusting the lead-out length of the pump wiring 18 from the wiring lead-out part 11, the wiring lead-out part 11 is sealed with a sealing member such as packing. The pump wiring 18 drawn from the wiring lead-out part 11 is connected to the electrode 2d of the main body dividing part 2b.
Next, by engaging the stopper 15 of the liquid suction pipe lead-out part 14 of the main body dividing part 2b with the pipe side locking part 10, the liquid suction pipe 3 is pulled out from the liquid suction pipe lead-out part 14, and the liquid injection hose lead-out part 16 is drawn. Is engaged with the hose side locking portion 13 to draw out the liquid injection hose 6 from the liquid injection hose extraction portion 16. Next, the main body split part 2b is abutted from the liquid injection hose lead-out part 16 and joined by bonding, welding or the like to form the main body 2. Thereby, the liquid pump 1 in Embodiment 1 can be manufactured.

以上のように構成された本発明の実施の形態１における液体ポンプについて、図面を参照しながら、以下その使用方法を説明する。
図３は本発明の実施の形態１における液体ポンプを用いて液体容器から移送用容器へ液体を移送する状態を示す一部破断正面図であり、図４は本発明の実施の形態１における液体ポンプの保管時の状態を示す正面図である。
図３において、２０は灯油等の液体が収容された液体容器、２１は液体容器２０の口部、２２は灯油ストーブのカートリッジタンク等の液体の移送先容器、２３は移送先容器２２の口部である。 About the liquid pump in Embodiment 1 of this invention comprised as mentioned above, the usage method is demonstrated below, referring drawings.
FIG. 3 is a partially broken front view showing a state in which the liquid is transferred from the liquid container to the transfer container using the liquid pump in the first embodiment of the present invention, and FIG. 4 is a liquid in the first embodiment of the present invention. It is a front view which shows the state at the time of storage of a pump.
In FIG. 3, 20 is a liquid container in which a liquid such as kerosene is accommodated, 21 is a mouth of the liquid container 20, 22 is a liquid destination container such as a cartridge tank of a kerosene stove, and 23 is a mouth of the destination container 22. It is.

液体容器２０から移送先容器２２へ液体を移送するときには、図３に示すように、液体容器２０の口部２１から吸液管３を液体容器２０内に挿入し、移送先容器２２の口部２３に注液ホース先端部７を挿入する。液体容器２０と移送先容器２２の間隔や移送先容器２２の口部２３の高さに応じ、蛇腹部９の屈曲度や蛇腹部８の伸縮度を調整することで、注液ホース６や注液ホース先端部７を手で押さえなくても、注液ホース６が屈曲した状態を維持させることができる。本体２に形成された図示しないスイッチを操作してポンプ装置１７を駆動させると、液体容器２０内の液体を移送先容器２３に移送させることができる。 When transferring the liquid from the liquid container 20 to the transfer destination container 22, as shown in FIG. 3, the liquid absorption pipe 3 is inserted into the liquid container 20 from the mouth portion 21 of the liquid container 20, and the mouth portion of the transfer destination container 22. 23, the injection hose tip 7 is inserted. By adjusting the bending degree of the bellows part 9 and the expansion / contraction degree of the bellows part 8 according to the distance between the liquid container 20 and the transfer destination container 22 and the height of the mouth part 23 of the transfer destination container 22, The liquid injection hose 6 can be kept bent without holding the liquid hose tip 7 by hand. When the pump device 17 is driven by operating a switch (not shown) formed on the main body 2, the liquid in the liquid container 20 can be transferred to the transfer destination container 23.

液体ポンプ１を保管する際には、図４に示すように、注液ホース６の蛇腹部８，９を屈曲させて、注液ホース先端部７を上向きの状態に維持させることができる。これにより、注液ホース６をコンパクトに収めることができるとともに、注液ホース６の内壁面に付着した液体が注液ホース先端部７から滴下するのを防止できる。 When the liquid pump 1 is stored, as shown in FIG. 4, the bellows portions 8 and 9 of the liquid injection hose 6 can be bent to maintain the liquid injection hose tip 7 in an upward state. Thereby, the liquid injection hose 6 can be stored in a compact manner, and the liquid adhering to the inner wall surface of the liquid injection hose 6 can be prevented from dripping from the liquid injection hose front end portion 7.

以上のように、本発明の実施の形態１における液体ポンプは構成されているので、以下のような作用が得られる。
（１）注液ホース６が吸液管３よりも短いので、液体を移送し終えた際に注液ホース６を移送先容器２２側へ傾けることで、注液ホース６内の液体を残らず移送先容器２２に移送させることができる。また、注液ホース６の内表面積を小さくできるため、液体が注液ホース６の内面に付着する量も減らすことができる。そのため、注液ホース先端部７を移送先容器２２の口部２３から外した際に、注液ホース先端部７より吐出される液体の量を極めて少なくすることができ、床を汚す等の問題が生じ難い。
（２）吸液管３と注液ホース６を合わせた全長を短くできるため、液体を移送する際、ポンプ装置１７の能力が同じであれば、液体が液体ポンプ１内を通過する時間を短縮でき、その結果、液体を移送するのに要する時間を短縮できる。
（３）注液ホース６が吸液管３よりも短いので、注液ホース６が嵩張ることなく液体ポンプ１をコンパクトに保管できる。
（４）注液ホース６が短いので、注液ホース６の原料コストを削減することができるとともに省資源性に優れる。
（５）注液ホース６が吸液管３よりも短いので、液体を移送する際、移送先容器２２に移送された液体に注液ホース先端部７が浸かることがないためサイホン現象を防止でき、従来の液体ポンプのように、液体戻し溝から液体を容器内に戻すような流量損失がないため、従来の流量損失分を上乗せして流量を増加させることができる。
（６）吸液管３と注液ホース６が一体成形されているので、従来の液体ポンプのように、吸液管と注液ホースを別々に成形して、本体を介して吸液管と注液ホースが連通するように組み立てるという製造工程が不要なため、生産性に優れる。
（７）吸液管３と注液ホース６が一体成形されているので、吸液管や注液ホースの接合箇所から液漏れが生じる等の不具合が生じることがなく、また製品得率も高めることができる。
（８）本体分割部２ｂが２体組み合わされて本体２が形成されているので、一体成形された吸液管３と注液ホース６を本体分割部２ｂの吸液管引出部１４や注液ホース引出部１６に嵌め込み、２体の本体分割部２ｂを接合するだけで液体ポンプ１を製造することができるため、生産性に著しく優れる。
（９）注液ホース６が屈曲可能に形成され屈曲状態で形状維持できる蛇腹部８，９を備えているので、液体を移送する際、注液ホース６が屈曲した状態を維持させることができるため、注液ホース先端部７を移送先容器２２の口部２３に押え付けておかなくても、移送用容器２２の口部２３に挿入した注液ホース先端部７が外れてしまう不具合を防止できる。
（１０）注液ホース６が屈曲可能に形成され屈曲状態で形状維持できる蛇腹部８，９を備えているので、液体ポンプ１を保管する際に、注液ホース６を屈曲させて注液ホース先端部７を上向きの状態に維持させることができるため、注液ホース６の内壁面に付着した液体が注液ホース先端部７から滴下するのを防止できる。
（１１）一体成形された吸液管３と注液ホース６が管側係止部１０とホース側係止部１３とを備えており、管側係止部１０とホース側係止部１３の間に屈曲可能な蛇腹部１３が形成されているので、本体分割部２ｂの吸液管引出部１４を管側係止部１０に係合させ、本体分割部２ｂの注液ホース引出部１６をホース側係止部１３に係合させることで、本体２の下部に吸液管３を延設させ、本体２の側部に注液ホース６を延設させることができる。
（１２）本体引出部１１が管側係止部１０の上部に形成されているので、配線引出部１１を本体２で隠蔽して見栄えを良くすることができるとともに、ポンプ用配線１８を吸液管３及び本体２に内蔵できるため、外力が加わり難くポンプ用配線１８が断線するのを防止できる。 As described above, since the liquid pump according to the first embodiment of the present invention is configured, the following operation is obtained.
(1) Since the liquid injection hose 6 is shorter than the liquid suction pipe 3, the liquid in the liquid injection hose 6 does not remain by tilting the liquid injection hose 6 toward the transfer destination container 22 when the liquid has been transferred. It can be transferred to the transfer destination container 22. Further, since the inner surface area of the liquid injection hose 6 can be reduced, the amount of liquid adhering to the inner surface of the liquid injection hose 6 can also be reduced. For this reason, when the liquid injection hose tip 7 is removed from the mouth 23 of the transfer destination container 22, the amount of liquid discharged from the liquid injection hose tip 7 can be extremely reduced, and the floor is soiled. Is unlikely to occur.
(2) Since the total length of the liquid suction pipe 3 and the liquid injection hose 6 can be shortened, the time for the liquid to pass through the liquid pump 1 is shortened if the capacity of the pump device 17 is the same when the liquid is transferred. As a result, the time required to transfer the liquid can be shortened.
(3) Since the liquid injection hose 6 is shorter than the liquid suction pipe 3, the liquid pump 1 can be stored compactly without the liquid injection hose 6 being bulky.
(4) Since the liquid injection hose 6 is short, the raw material cost of the liquid injection hose 6 can be reduced and resource saving is excellent.
(5) Since the liquid injection hose 6 is shorter than the liquid suction pipe 3, the siphon phenomenon can be prevented because the liquid injection hose tip 7 is not immersed in the liquid transferred to the transfer destination container 22 when the liquid is transferred. Since there is no flow loss that returns the liquid from the liquid return groove into the container as in the conventional liquid pump, the flow rate can be increased by adding the conventional flow loss.
(6) Since the liquid absorption pipe 3 and the liquid injection hose 6 are integrally formed, the liquid absorption pipe and the liquid injection hose are separately formed as in a conventional liquid pump, and the liquid absorption pipe is formed through the main body. Since the manufacturing process of assembling so that the injection hose communicates is unnecessary, the productivity is excellent.
(7) Since the liquid suction pipe 3 and the liquid injection hose 6 are integrally formed, there is no problem such as liquid leakage from the joint between the liquid suction pipe and the liquid injection hose, and the product yield is also increased. be able to.
(8) Since the main body 2 is formed by combining the two main body dividing parts 2b, the integrally formed liquid absorption pipe 3 and liquid injection hose 6 are connected to the liquid absorption pipe drawing part 14 and liquid injection of the main body divided part 2b. Since the liquid pump 1 can be manufactured simply by fitting into the hose lead-out portion 16 and joining the two main body divided portions 2b, the productivity is remarkably excellent.
(9) Since the liquid injection hose 6 is formed to be bendable and includes the bellows portions 8 and 9 that can maintain the shape in the bent state, the liquid injection hose 6 can be kept bent when the liquid is transferred. Therefore, even if the injection hose tip 7 is not pressed against the mouth 23 of the transfer destination container 22, the trouble that the injection hose tip 7 inserted into the mouth 23 of the transfer container 22 comes off is prevented. it can.
(10) Since the liquid injection hose 6 is formed to be bendable and has the bellows portions 8 and 9 that can maintain the shape in the bent state, the liquid injection hose 6 is bent when the liquid pump 1 is stored. Since the tip 7 can be maintained in an upward state, it is possible to prevent the liquid adhering to the inner wall surface of the liquid injection hose 6 from dripping from the liquid injection hose tip 7.
(11) The integrally formed liquid absorption pipe 3 and liquid injection hose 6 are provided with a pipe side locking part 10 and a hose side locking part 13, and the tube side locking part 10 and the hose side locking part 13 Since the bendable bellows portion 13 is formed between them, the liquid suction pipe lead-out portion 14 of the main body split portion 2b is engaged with the pipe-side locking portion 10, and the liquid injection hose lead-out portion 16 of the main body split portion 2b is connected. By engaging with the hose side locking portion 13, the liquid absorption tube 3 can be extended to the lower portion of the main body 2, and the liquid injection hose 6 can be extended to the side portion of the main body 2.
(12) Since the main body drawing portion 11 is formed at the upper part of the pipe side locking portion 10, the wiring drawing portion 11 can be concealed by the main body 2 to improve the appearance, and the pump wiring 18 can be absorbed. Since it can be built in the tube 3 and the main body 2, it is difficult to apply an external force and the pump wiring 18 can be prevented from being disconnected.

なお、本実施の形態において、吸液管３が貫装された取付けキャップを本体２の下部に設ける場合もある。口部２１から吸液管３を液体容器２０に挿入し、口部２１に取付けキャップを取り付けることで、液体容器２０の口部２１に本体２を固定することができる。移送先容器２３への液体の移送が終わったら、図４に示すように、蛇腹部８，９を屈曲させて注液ホース先端部７を本体２の近くに引き寄せておくことができる。未使用時に、注液ホース先端部７にゴミや埃が付着しないようにするため、本体２に注液ホース先端部７の覆いを設けることもできる。
また、本実施の形態において、注液ホース先端部７に液面センサを設ける場合もある。液面センサを本体２に接続し、移送先容器２２に所定量の液体が移送されたらポンプ装置１７を停止させるように設定しておくことで、移送先容器２２の口部２３から液体が溢れてしまうのを防止できる。この場合は、注液ホース６の内径を吸液管３の内径よりも大きくするのが好ましい。吸液管３に内設されたポンプ装置１７で形成された気泡が注液ホース先端部付近の液面を覆うと、液面センサの動作が泡に邪魔されて不安定になることがあるが、注液ホース６の内径を大きくすることにより、注液ホース６内の流速が遅くなり、気泡を消すことができるため、液面センサの動作の安定性を高めることができるからである。
また、液体の移送時に、注液ホース先端部７を移送先容器２２の口部２３に係着又は嵌着して取り付けることができるような取付部を、注液ホース先端部７に設けるのが好ましい。液体の移送時に、移送用容器２２の口部２３に挿入した注液ホース先端部７が外れてしまう不具合を防止するためである。取付部としては、口部２３に嵌着する蓋や膨らみ、口部２３に係着するフックや溝等が用いられる。 In the present embodiment, a mounting cap through which the liquid suction pipe 3 is inserted may be provided in the lower part of the main body 2. The main body 2 can be fixed to the mouth portion 21 of the liquid container 20 by inserting the liquid absorption tube 3 into the liquid container 20 from the mouth portion 21 and attaching a mounting cap to the mouth portion 21. When the transfer of the liquid to the transfer destination container 23 is completed, the bellows portions 8 and 9 can be bent to draw the liquid injection hose tip 7 close to the main body 2 as shown in FIG. In order to prevent dust and dirt from adhering to the injection hose tip 7 when not in use, the main body 2 can be provided with a cover of the injection hose tip 7.
In the present embodiment, a liquid level sensor may be provided at the tip 7 of the liquid injection hose. By connecting the liquid level sensor to the main body 2 and setting the pump device 17 to stop when a predetermined amount of liquid is transferred to the transfer destination container 22, the liquid overflows from the mouth 23 of the transfer destination container 22. Can be prevented. In this case, the inner diameter of the liquid injection hose 6 is preferably larger than the inner diameter of the liquid suction pipe 3. If bubbles formed by the pump device 17 installed in the liquid suction pipe 3 cover the liquid surface near the tip of the liquid injection hose, the operation of the liquid level sensor may be disturbed by bubbles and become unstable. This is because by increasing the inner diameter of the liquid injection hose 6, the flow rate in the liquid injection hose 6 is slowed down and the bubbles can be eliminated, so that the stability of the operation of the liquid level sensor can be improved.
In addition, the liquid injection hose front end portion 7 is provided with an attachment portion that can attach or fit the liquid injection hose front end portion 7 to the mouth portion 23 of the transfer destination container 22 during the liquid transfer. preferable. This is to prevent a problem that the injection hose front end portion 7 inserted into the mouth portion 23 of the transfer container 22 is detached during the transfer of the liquid. As the attachment portion, a lid or a bulge that fits into the mouth portion 23, a hook or a groove that engages with the mouth portion 23, or the like is used.

本発明は、液体容器の口部から挿入し、液体容器内の液体を移送先容器へ移送する液体ポンプに関し、移送させる液体の流量を増加させることができるため液体の移送時間を短縮でき、また液体を移送し終えて注液ホースの先端部を移送先容器の口部から外した際、液体が注液ホースの先端部より吐出されることがほとんどなく床を汚す等の問題が生じ難く、さらにホースが嵩張ることなくコンパクトに保管できる液体ポンプを提供できる。 The present invention relates to a liquid pump that is inserted from the mouth of a liquid container and transfers the liquid in the liquid container to a transfer destination container, and can increase the flow rate of the liquid to be transferred, thereby reducing the liquid transfer time. When the liquid transfer hose has been transferred and the tip of the injection hose has been removed from the mouth of the destination container, the liquid is hardly discharged from the tip of the injection hose, and problems such as fouling the floor are less likely to occur. Furthermore, the liquid pump which can be stored compactly without the hose being bulky can be provided.
