Description

本考案は、観賞魚用水槽内の水の入れ換えとゴミ取りに使用可能な水槽用ポンプに関する。 The present invention relates to an aquarium pump that can be used for exchanging water in an aquarium fish tank and removing garbage.

従来、観賞魚用水槽の水の入れ換え等に使用する水槽用ポンプでは、把持して操作するようなベローズポンプからなる吸水ポンプと、吸水ポンプの吸水側から延びる吸水管路と、吸水ポンプの排水側から延びる排水管路と、を備えるとともに、吸水管路の先端側に、砂利を捕捉してゴミを通過させるためのストレーナを配設させて構成されている（例えば、特許文献１及び特許文献２参照）。そして、吸水管路では、吸水ポンプ側の部位に、曲げ可能な蛇腹部が配設されるとともに、先端側では、形状保持性を有した透明パイプが配設されて、透明パイプの先端側に、ストレーナを設けたノズルが接続されていた。 Conventionally, in an aquarium pump used for replacement of water in an aquarium fish tank, a water absorption pump consisting of a bellows pump that is gripped and operated, a water absorption pipe line extending from the water absorption side of the water absorption pump, and drainage of the water absorption pump And a drainage pipe extending from the side, and a strainer for capturing gravel and allowing the dust to pass through is disposed on the front end side of the water absorption pipe (for example, Patent Document 1 and Patent Document). 2). In the water absorption pipe line, a bendable bellows portion is disposed at a portion on the water absorption pump side, and on the distal end side, a transparent pipe having shape retaining property is disposed on the distal end side of the transparent pipe. The nozzle provided with the strainer was connected.

この種の水槽用ポンプでは、使用時、吸水ポンプから延びた排水管路側を、水槽の外の下方に配置させたバケツ等で受けておき、吸水管路の先端側を蛇腹部で曲げて下向きとして、ノズルを水槽内の底部側に向け、そして、吸水ポンプを把持して、水槽内の水をノズルから透明パイプや吸水ポンプを経てバケツ側に送り、その後、サイホンの原理を利用しつつ、形状保持性を有した透明パイプを把持して、ノズルを所定の方向に向けつつ、水槽底部の砂利を吸水ポンプ側に吸い込まないようにし、かつ、砂利の間から水草や糞等のゴミを吸い込むようにして、水槽内の水を吸引していた。
意匠登録第１１５８１８７号公報特開平１１−３２５０００号公報 In this type of aquarium pump, when used, the drain pipe side extending from the water suction pump is received by a bucket or the like disposed below the water tank, and the tip side of the water suction pipe is bent downward at the bellows part. As the nozzle is directed to the bottom side in the water tank, and the water absorption pump is gripped, the water in the water tank is sent from the nozzle to the bucket side through the transparent pipe and the water absorption pump, and then using the principle of siphon, Grasp the shape-retaining transparent pipe, keep the nozzle in the specified direction, keep the gravel at the bottom of the aquarium from being sucked into the suction pump side, and suck in dust such as aquatic plants and feces from between the gravel In this way, water in the water tank was sucked.

しかし、従来の水槽用ポンプでは、透明パイプの長さが、通常の水槽の高さ程度（２５〜５０ｃｍ程度）と略等しい２５〜４０ｃｍ程度としていた。そのため、深さ１０〜１５ｃｍ程度の浅い水槽の水を吸い込む際には、水槽から透明パイプの元部側が大きく上方へ出てしまい、透明パイプが邪魔をして、ノズルを所定の部位に配置させることに不便となる場合があった。また、浅い水槽では、水槽内に入っている水の量も少ないことから、吸水を完了しようとしてノズルを水面から上げると、透明パイプ内の水が水槽内に戻ってしまい、水換えする水の量の割合も低くさせてしまう。 However, in the conventional water tank pump, the length of the transparent pipe is about 25 to 40 cm which is substantially equal to the height of the normal water tank (about 25 to 50 cm). Therefore, when sucking the water of a shallow aquarium having a depth of about 10 to 15 cm, the base side of the transparent pipe largely goes out from the aquarium, and the transparent pipe obstructs the nozzle so that the nozzle is arranged at a predetermined site. It was particularly inconvenient. In addition, in a shallow aquarium, the amount of water contained in the aquarium is small, so when the nozzle is lifted from the water surface to complete the water absorption, the water in the transparent pipe returns to the aquarium and the water to be replaced is changed. The ratio of the amount is also lowered.

また、砂利の間のゴミを取り除く際、ノズルのストレーナに直ちに砂利が当たるため、効率的にごみを取り除き難かった。 Moreover, when removing dust between gravel, gravel hits the strainer of the nozzle immediately, so it was difficult to remove dust efficiently.

本考案は、上述の課題を解決するものであり、水の入れ換え等において、深さを異ならせた水槽に容易に対処できて、ゴミ取りも効率的に行うことができる水槽用ポンプを提供することを目的とする。 The present invention solves the above-described problems, and provides a water tank pump that can easily deal with water tanks of different depths and can efficiently perform dust removal when replacing water. For the purpose.

本考案に係る水槽用ポンプは、観賞魚用水槽内の水の入れ換えとゴミ取りに使用可能に、把持して操作する吸水ポンプと、吸水ポンプの吸水側から延びて、砂利を捕捉してゴミを通過させるためのストレーナを配設させた吸水管路と、吸水ポンプの排水側から延びる排水管路と、を備えて、吸水管路の先端側を水槽内に挿入させて使用する水槽用ポンプであって、
吸水管路が、吸水ポンプに連なって蛇腹部を有して曲げ可能とするポンプ側ホースと、ポンプ側ホースに着脱自在に取り付けられて形状保持性を有した円筒状の透明パイプと、透明パイプに着脱自在に取り付け可能としてストレーナを備えた円筒状のノズルと、を備えて構成され、
ノズルが、先端側を、透明パイプにおけるポンプ側ホースとのホース側接続部に対して着脱自在に接続可能とし、元部側を、透明パイプの先端側に対して着脱可能とするとともに、ポンプ側ホースにおける透明パイプとのパイプ側接続部に対して着脱自在に接続可能として、構成されていることを特徴とする。 The aquarium pump according to the present invention can be used for exchanging water in the aquarium fish tank and removing dust, and extends from the water absorption side of the water absorption pump to grasp and remove gravel. A water tank pump comprising a water suction pipe having a strainer for passing water and a drain pipe extending from the drain side of the water suction pump, and the tip side of the water suction pipe is inserted into the water tank. Because
A pump-side hose that has a water-absorbing pipe connected to the water-absorbing pump and has a bellows portion that can be bent, a cylindrical transparent pipe that is detachably attached to the pump-side hose and has a shape retaining property, and a transparent pipe A cylindrical nozzle with a strainer that is detachably attachable to the
The nozzle allows the tip side to be detachably connected to the hose side connection with the pump side hose in the transparent pipe, and the base side is detachable to the tip side of the transparent pipe, and the pump side The hose is configured to be detachably connectable to a pipe-side connecting portion with a transparent pipe.

本考案に係る水槽用ポンプでは、通常の使用時には、吸水管路において、ポンプ側ホースに透明パイプを接続し、その透明パイプの先端にノズルを接続させて使用する。この通常使用時には、吸水ポンプから延びた排水管路側を、水槽の外の下方に配置させたバケツ等で受けておき、ポンプ側ホースの蛇腹部で曲げて、ノズルを水槽内の底部側に向け、そして、吸水ポンプを把持操作して、水槽内の水をノズルから透明パイプや吸水ポンプを経てバケツ側に送り、その後、サイホンの原理を利用しつつ、形状保持性を有した透明パイプの上端付近を把持して、ノズルを所定の方向に向けつつ、ストレーナに捕捉される水槽底部の砂利を吸水ポンプ側に吸い込まないようにし、かつ、砂利の間から水草や糞等のゴミを吸い込むようにして、水槽内の水を吸引する。 In the water tank pump according to the present invention, during normal use, a transparent pipe is connected to the pump-side hose and a nozzle is connected to the tip of the transparent pipe in the water absorption pipe. During normal use, the drain line extending from the water absorption pump is received by a bucket or the like placed below the water tank, bent at the bellows of the pump hose, and the nozzle directed toward the bottom of the water tank. Then, by gripping the water absorption pump, the water in the water tank is sent from the nozzle to the bucket side through the transparent pipe or the water absorption pump, and then the upper end of the transparent pipe having shape retention while using the principle of siphon. Grab the vicinity, turn the nozzle in the specified direction, do not suck the gravel at the bottom of the water tank captured by the strainer to the suction pump side, and suck in dust such as aquatic plants and feces from between the gravel Suck the water in the tank.

そして、高さの低い水槽の水を吸引する場合には、吸水管路において、透明パイプを使用せずに、ポンプ側ホースの先端に、直接、ノズルを接続させて使用する。この場合の使用時には、ノズル付近を把持して、高さの低い水槽の底部にノズルを向けて、水槽内の水を吸引する。この作業は、透明パイプが無いことから、ノズル付近を把持して、直接、ノズルの操作が行えて、作業を円滑に行うことができる。また、吸水を完了しようとしてノズルを水面から上げても、透明パイプが無いことから、ノズルから水槽上端付近のポンプ側ホースの部位までの短い長さ分の水が水槽内に戻るだけであり、水換えする水の量の割合を増加させることもできる。 And when sucking the water of the tank with a low height, a nozzle is directly connected to the tip of the pump side hose in the water absorption pipe line without using a transparent pipe. In use in this case, the vicinity of the nozzle is gripped, the nozzle is directed to the bottom of the low-water tank, and the water in the water tank is sucked. Since this operation does not have a transparent pipe, the nozzle can be directly operated by gripping the vicinity of the nozzle, and the operation can be performed smoothly. Also, even if the nozzle is lifted from the water surface in an attempt to complete water absorption, there is no transparent pipe, so only a short length of water from the nozzle to the pump hose near the top of the aquarium returns into the aquarium, It is also possible to increase the ratio of the amount of water to be changed.

さらに、砂利の間のゴミを効率的に吸い込む場合には、吸水管路において、ポンプ側ホースにノズルを接続し、そのノズルの先端に透明パイプを接続させて使用する。この場合の使用時には、透明パイプの先端側を下向きにして水槽底部の砂利の部位に差し込む等して、水槽内の水を吸引すれば、水流の影響により、砂利が、透明パイプの下端側から侵入して上端側のノズルの部位まで（透明パイプの長さ分）上昇し、その際、透明パイプの内周面や砂利相互で擦れて、砂利の間に詰まっていたゴミや、砂利に付着していたゴミを剥離させて、効率的にゴミを吸い込むことができる。勿論、透明パイプの上端側には、ゴミを通過させて砂利を捕捉するためのストレーナを有したノズルが配設されており、砂利や魚を吸水ポンプ側に通過させないことから、吸水ポンプの弁等の故障や魚の傷付けを防止できる。 Further, in order to efficiently suck in dust between gravel, a nozzle is connected to the pump-side hose in the water absorption pipe, and a transparent pipe is connected to the tip of the nozzle. In this case, if the water in the aquarium is sucked in by inserting the gravel part at the bottom of the aquarium with the tip of the transparent pipe facing down, gravel will be removed from the lower end of the transparent pipe due to the influence of the water flow. It penetrates and rises to the nozzle part on the upper end side (the length of the transparent pipe). At that time, it rubs against the inner peripheral surface of the transparent pipe and the gravel and adheres to the dust and gravel clogged between the gravel The garbage that has been removed can be peeled off and the garbage can be sucked in efficiently. Of course, on the upper end side of the transparent pipe, a nozzle having a strainer for passing gravel and capturing gravel is disposed, and gravel and fish are not allowed to pass to the water absorption pump side. This can prevent malfunctions and fish damage.

したがって、本考案に係る水槽用ポンプでは、水の入れ換え等において、深さを異ならせた水槽に容易に対処できて、ゴミ取りも効率的に行うことができる。 Therefore, the water tank pump according to the present invention can easily cope with water tanks of different depths in the replacement of water and the like, and can efficiently remove dust.

そして、本考案に係る水槽用ポンプでは、次のように構成することが望ましい。透明パイプは、全長にわたって内外径の寸法を均等とした円筒形として、ノズルの先端側は、透明パイプを挿入させて嵌合可能に、内径寸法を、透明パイプの外径寸法に対応させて構成する。さらに、ノズルの元部側は、外径寸法を透明パイプの外径寸法と略等しくさせた大径筒部と、大径筒部から突出して、透明パイプに対して挿入させて嵌合可能な小径筒部と、を設けて構成する。そして、ポンプ側ホースのパイプ側接続部は、透明パイプとノズルとを挿入させて嵌合可能に、内径寸法を透明パイプとノズルの大径筒部との外径寸法に対応させた先側筒部と、先側筒部の奥側に連なって、内径寸法をノズルの小径筒部に対応させた奥側筒部と、を配設させて構成するとともに、外周側に、先側筒部における透明パイプとノズルの大径筒部との接続時の外周面を内周側に押圧可能に、弾性変形可能な固定リングを配設させて構成する。 The aquarium pump according to the present invention is preferably configured as follows. The transparent pipe has a cylindrical shape with uniform inner and outer diameters over its entire length, and the tip end side of the nozzle can be fitted by inserting the transparent pipe, and the inner diameter is configured to correspond to the outer diameter of the transparent pipe. To do. In addition, the base part side of the nozzle can be fitted with a large-diameter cylindrical part having an outer diameter dimension substantially equal to the outer diameter dimension of the transparent pipe, protruding from the large-diameter cylindrical part, and inserted into the transparent pipe. A small-diameter cylindrical portion. And the pipe side connection part of the pump side hose is a front side tube in which the transparent pipe and the nozzle can be inserted and fitted so that the inner diameter dimension corresponds to the outer diameter dimension of the transparent pipe and the large diameter cylindrical part of the nozzle. And a rear side cylinder part having an inner diameter dimension corresponding to the small diameter cylindrical part of the nozzle, arranged on the back side of the front side cylinder part, An elastically deformable fixing ring is disposed so that the outer peripheral surface at the time of connection between the transparent pipe and the large-diameter cylindrical portion of the nozzle can be pressed toward the inner peripheral side.

このような構成では、ポンプ側ホースのパイプ側接続部は、透明パイプと接続される場合には、先側筒部に透明パイプを挿入嵌合させて行い、ノズルと接続させる場合には、奥側筒部にノズルの小径筒部を挿入嵌合させ、かつ、先側筒部にノズルの大径筒部を挿入嵌合させて行う。そして、これらの嵌合時に、固定リングをパイプ側接続部における先側筒部の外周側に嵌めれば、先側筒部が透明パイプやノズルの大径筒部に押し付けられて、シール性良く、接続させることができる。 In such a configuration, the pipe-side connecting portion of the pump-side hose is inserted and fitted with the transparent pipe into the front-side tube portion when connected to the transparent pipe, and when connected to the nozzle, This is performed by inserting and fitting the small-diameter cylindrical portion of the nozzle into the side cylindrical portion, and inserting and fitting the large-diameter cylindrical portion of the nozzle into the front-side cylindrical portion. When these fittings are carried out, if the fixing ring is fitted to the outer peripheral side of the front-side cylinder part in the pipe-side connection part, the front-side cylinder part is pressed against the large-diameter cylinder part of the transparent pipe or nozzle and has a good sealing property. Can be connected.

また、このような構成では、浅い水槽の水換え時において、ポンプ側ホースのパイプ側接続部にノズルを接続させる際、相互の嵌合部位は、奥側筒部に小径筒部が挿入嵌合され、かつ、先側筒部に大径筒部が挿入嵌合されて、ある程度の長さの剛性部位となって、浅い水槽の水を吸引する際のノズル操作時、ノズル先端側を水の中に入れて、嵌合部位近傍の付近のポンプ側ホースの部位を水面上で把持して、手を水の中に入れずに、ノズルを操作することができる。 In such a configuration, when the nozzle is connected to the pipe side connection part of the pump side hose at the time of changing the water in the shallow aquarium, the small diameter cylindrical part is inserted and fitted into the back side cylindrical part. In addition, the large-diameter cylindrical portion is inserted and fitted into the front-side cylindrical portion to form a rigid portion of a certain length, and when the nozzle is operated when sucking water from a shallow aquarium, It is possible to operate the nozzle without putting the hand into the water by holding the pump-side hose near the fitting part on the water surface.

また、透明パイプを水槽の内周面に固定可能に、透明パイプの外周に、水槽の内周面に吸着可能な吸盤を、配設させておけば、吸盤を水槽の内周面に吸着させて、透明パイプを水槽に固定しておくことができて、透明パイプから手を離して、吸水ポンプ等の操作を行うことができる。 If a suction cup that can be adsorbed to the inner peripheral surface of the water tank is provided on the outer periphery of the transparent pipe so that the transparent pipe can be fixed to the inner peripheral surface of the water tank, the suction cup is adsorbed to the inner peripheral surface of the water tank. Thus, the transparent pipe can be fixed to the water tank, and the water absorption pump or the like can be operated by releasing the hand from the transparent pipe.

さらに、ポンプ側ホースに、周壁を曲げ可能として、内周側の開口面積を調整可能な流量調整部を配設させるとともに、流量調整部の外周側に、流量調整部の内周側の開口面積を大、中、小と調整可能な三種類の開口面積の穴部を有した挿通孔を備えた流量調整器を、装着させてもよい。このような構成では、流量調整器の挿通孔における所定の穴部に、ポンプ側ホースの流量調整部を配置させれば、開口面積を大、中、小と変化させるように流量調整部を曲げることができて、流量を調整して水を吸い込むことができ、水の減りに応じて掃除や魚を採る等の作業を効率的に行うことができる。勿論、ポンプ側ホースの流量調整部自体を摘んで閉じれば、水の吸い込み自体を中断できて、透明パイプや吸水ポンプ側への細かい砂や魚等の侵入を緊急停止できる。 Furthermore, the pump-side hose is provided with a flow rate adjusting unit capable of adjusting the opening area on the inner peripheral side so that the peripheral wall can be bent, and on the outer peripheral side of the flow rate adjusting unit, the opening area on the inner peripheral side of the flow rate adjusting unit A flow rate regulator having an insertion hole having three types of opening areas that can be adjusted to large, medium, and small may be attached. In such a configuration, if the flow rate adjustment part of the pump side hose is arranged in a predetermined hole part in the insertion hole of the flow rate regulator, the flow rate adjustment part is bent so as to change the opening area from large to medium to small. It is possible to adjust the flow rate so as to suck in water, and it is possible to efficiently perform operations such as cleaning and collecting fish according to the decrease in water. Of course, if the flow rate adjusting part itself of the pump side hose is picked and closed, the water suction itself can be interrupted, and the invasion of fine sand or fish into the transparent pipe or the water absorption pump side can be stopped urgently.

以下、本考案の一実施形態を図面に基づいて説明すると、実施形態の水槽用ポンプ１０は、図１〜４に示すように、把持して操作する吸水ポンプ１１と、吸水ポンプ１１の吸水側から延びて、砂利を捕捉してゴミを通過させるためのストレーナ３０（図２と図３参照）を配設させた吸水管路１６と、吸水ポンプ１１の排水側から延びる排水管路１３と、を備えて構成されている。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The rear side cylinder portion 23 has an inner diameter dimension H2 corresponding to the outer diameter dimension ND2 of the small diameter cylinder portion 34 of the nozzle 29 (H2≈ND2).

また、先側筒部２２の外周側には、先側筒部２２における透明パイプ２５やノズル２９の大径筒部３３との接続時の外周面を内周側に押圧可能に、弾性変形可能な固定リング３８が配設されている。この固定リング３８は、ポリオレフィン系等の熱可塑性エラストマーやゴム等から形成されている。なお、実施形態では、吸水ポンプ１１の吸水口部１１ｂと排水口部１１ｃとの接続部位にも、同様な固定リング３６が使用されている。 Moreover, the outer peripheral side of the front side cylinder part 22 can be elastically deformed so that the outer peripheral surface of the front side cylinder part 22 when connected to the transparent pipe 25 or the large diameter cylindrical part 33 of the nozzle 29 can be pressed to the inner peripheral side. A fixed ring 38 is provided. The fixing ring 38 is made of a thermoplastic elastomer such as polyolefin or rubber. In the embodiment, the same fixing ring 36 is also used at the connection portion between the water inlet 11b and the water outlet 11c of the water pump 11.

流量調整部２０は、内周側の開口面積を調整できるように、周壁を曲げ可能とした円筒形状として形成されている。この流量調整部２０の外周側には、流量調整器４２が、装着されている。流量調整器４２は、図１と図８に示すように、流量調整器４２の内周側の開口面積を大、中、小と調整可能な三種類の開口面積の穴部（大開口部４４、中開口部４５、及び、小開口部４６）を有した挿通孔４３を備えて構成されている。流量調整器４２は、ポリプロピレンの硬質合成樹脂から形成され、挿通孔４３の３つの大開口部４４、中開口部４５、及び、小開口部４６に、流量調整部２０を嵌めれば、流量調整部２０における水Ｗの通る開口面積が大、中、小とそれぞれ調整される。 The flow rate adjusting unit 20 is formed in a cylindrical shape in which the peripheral wall can be bent so that the opening area on the inner peripheral side can be adjusted. A flow rate regulator 42 is mounted on the outer peripheral side of the flow rate adjustment unit 20. As shown in FIGS. 1 and 8, the flow regulator 42 has three types of opening areas (large openings 44) that can be adjusted to have a large, medium, and small opening area on the inner peripheral side of the flow regulator 42. The insertion hole 43 has a middle opening 45 and a small opening 46). The flow regulator 42 is formed of a hard polypropylene synthetic resin. If the flow regulator 20 is fitted into the three large openings 44, the middle opening 45, and the small opening 46 of the insertion hole 43, the flow regulator 42 is adjusted. The opening area through which the water W passes in the portion 20 is adjusted to be large, medium, and small, respectively.

なお、実施形態の水槽用ポンプ１０では、流量調整部２０を大開口部４４に配置させて、流量調整部２０の開口面積を最大としても、流量調整部２０自体の内径寸法や、他の部位のポンプ側ホース１７の蛇腹部１９や透明パイプ２５の内径寸法が、通常の水槽用ポンプより小さく形成されており、吸水時に従来品より水の減りを抑えることができて、吸水中での水槽内の掃除等を行い易く構成されている。 In the aquarium pump 10 of the embodiment, even if the flow rate adjusting unit 20 is disposed in the large opening 44 and the opening area of the flow rate adjusting unit 20 is maximized, the inner diameter dimension of the flow rate adjusting unit 20 itself, and other parts The inner diameter dimension of the bellows portion 19 and the transparent pipe 25 of the pump-side hose 17 is smaller than that of a normal water tank pump, and the water tank can suppress the reduction of water as compared with the conventional product at the time of water absorption. It is configured to facilitate cleaning inside.

透明パイプ２５は、蛇腹ホース１４やポンプ側ホース１７よりも剛性の高い形状保持性を有しており、実施形態の場合、透明な硬質塩化ビニル等の合成樹脂製としている。また、実施形態の透明パイプ２５は、元部２５ａ側のホース側接続部２６から先端部２５ｂ側のノズル側接続部２７までの全長にわたって、内外径の寸法を均等とした円筒形として構成されている。 The transparent pipe 25 has a shape retaining property that is higher in rigidity than the bellows hose 14 and the pump-side hose 17.

The suction cup 40 includes a suction part 40a and an annular part 40b that can be fitted and attached to the outer periphery of the transparent pipe 25 so as to be elastically deformed.

ノズル２９は、透明パイプ２５とポンプ側ホース１７のパイプ側接続部２１に対して着脱自在に取り付けられるものであり、先端側を拡開させるようにテーパ状とした円筒状としている。ノズル２９は、前後方向の略中間位置の内部に、砂利６を捕捉してゴミ７を通過させるための細かい多数の穴３０ａを設けたストレーナ３０を配設させている。このノズル２９は、透明パイプ２５と同様な剛性の高い形状保持性を有しており、ポリプロピレン等の硬質合成樹脂から形成されている。 The nozzle 29 is detachably attached to the transparent pipe 25 and the pipe-side connecting portion 21 of the pump-side hose 17 and has a cylindrical shape that is tapered so as to expand the tip side. The nozzle 29 has a strainer 30 provided with a large number of fine holes 30a for capturing the gravel 6 and allowing the dust 7 to pass through in a substantially intermediate position in the front-rear direction. The nozzle 29 has a shape retaining property with high rigidity similar to that of the transparent pipe 25, and is made of a hard synthetic resin such as polypropylene.

また、ノズル２９のストレーナ３０より先端側の先端部３１は、拡開した先端側に複数の凹溝３１ａを設けて、吸水作業時における先端側が塞がれ難くし、吸水性能を低下させないように構成されている。先端部３１の内周面におけるストレーナ３０側の奥部３１ｂは、透明パイプ２５を挿入させて嵌合させ易いように、ストレート状として、内径寸法Ｎｄを透明パイプ２５の外径寸法ＰＤに対応させている（Ｎｄ≒ＰＤ）。 Further, the tip portion 31 on the tip side of the strainer 30 of the nozzle 29 is provided with a plurality of concave grooves 31a on the widened tip side so that the tip side is not easily blocked during the water absorption operation so that the water absorption performance is not deteriorated. It is configured. The inner portion 31b of the tip 31 on the strainer 30 side has a straight shape so that the transparent pipe 25 can be easily inserted and fitted, and the inner diameter dimension Nd corresponds to the outer diameter dimension PD of the transparent pipe 25. (Nd≈PD).

ノズル２９のストレーナ３０より元部側の元部３２は、透明パイプ２５の先端部２５ｂ側に対して着脱可能とするとともに、ポンプ側ホース１７のパイプ側接続部２１に対して着脱自在に接続される部位としている。そして、元部３２は、大径筒部３３と大径筒部３３から突出する小径筒部３４とを備えた段差の付いた円筒状としている。大径筒部３３は、ポンプ側ホース１７のパイプ側接続部２１における先側筒部２２に挿入させて嵌合可能に、外径寸法ＮＤ１を、透明パイプ２５の外径寸法ＰＤや先側筒部２２の内径寸法Ｈ１に対応させて設定されている（ＰＤ≒Ｈ１≒ＮＤ１）。小径筒部３４は、透明パイプ２５やポンプ側ホース１７のパイプ側接続部２１における奥側筒部２３に対して挿入させて嵌合可能に、外径寸法ＮＤ２を透明パイプ２５の内径寸法Ｐｄや奥側筒部２３の内径寸法Ｈ２に対応させている（Ｐｄ≒Ｈ２≒ＮＤ２）。 The base portion 32 of the nozzle 29 closer to the base portion than the strainer 30 is detachable from the distal end portion 25b side of the transparent pipe 25 and is detachably connected to the pipe side connection portion 21 of the pump side hose 17. It is a part to be. The base portion 32 has a cylindrical shape with a step including a large diameter cylindrical portion 33 and a small diameter cylindrical portion 34 protruding from the large diameter cylindrical portion 33. The large-diameter cylindrical portion 33 is inserted into the front-side cylindrical portion 22 in the pipe-side connecting portion 21 of the pump-side hose 17 so that the outer-diameter dimension ND1 can be fitted, and the outer-diameter dimension PD of the transparent pipe 25 or the front-side cylinder. It is set to correspond to the inner diameter dimension H1 of the portion 22 (PD≈H1≈ND1). The small-diameter cylindrical portion 34 is inserted into the rear-side cylindrical portion 23 of the transparent pipe 25 or the pipe-side connecting portion 21 of the pump-side hose 17 so that the outer diameter ND2 can be fitted. It corresponds to the inner diameter dimension H2 of the back side cylinder part 23 (Pd≈H2≈ND2).

この水槽用ポンプ１０を使用して通常の高さの水槽１の水換えを行う場合には、図４に示すように、水槽用ポンプ１０は、吸水管路１６において、ポンプ側ホース１７のパイプ側接続部２１に透明パイプ２５を接続し、その透明パイプ２５の先端部２５ｂ側にノズル２９を接続させて使用する（図２のＡ参照）。そして、この通常使用時には、排水管路１３の蛇腹ホース１４の先端部１４ｂ側を、水槽１の外の下方に配置させたバケツＶ等で受けておき、ポンプ側ホース１７の蛇腹部１９で曲げて、ノズル２９を水槽１内の底部３側に向け、そして、吸水ポンプ１１を把持操作して、水槽１内の水Ｗをノズル２９から透明パイプ２５や吸水ポンプ１１を経てバケツＶ側に送り、その後、サイホンの原理を利用しつつ、形状保持性を有した透明パイプ２５の上端付近を把持して、ノズル２９を所定の方向に向けつつ、ストレーナ３０に捕捉される水槽１の底部３の砂利６を吸水ポンプ１１側に吸い込まないようにし、かつ、砂利６の間から水草や糞等のゴミ７を吸い込むようにして、水槽１内の水Ｗを吸引する。 When the water tank 1 is changed to a normal height by using this water tank pump 10, the water tank pump 10 is connected to a pipe of a pump-side hose 17 in a water absorption pipe 16 as shown in FIG. 4. A transparent pipe 25 is connected to the side connection portion 21, and a nozzle 29 is connected to the distal end portion 25b side of the transparent pipe 25 for use (see FIG. 2A). In this normal use, the tip end 14b side of the bellows hose 14 of the drain line 13 is received by a bucket V or the like disposed below the outside of the water tank 1, and bent at the bellows part 19 of the pump side hose 17. Then, the nozzle 29 is directed to the bottom 3 side in the water tank 1 and the water absorption pump 11 is gripped to feed the water W in the water tank 1 from the nozzle 29 to the bucket V side through the transparent pipe 25 and the water absorption pump 11. Then, using the principle of siphon, gripping the vicinity of the upper end of the transparent pipe 25 having shape retaining property, directing the nozzle 29 in a predetermined direction, the bottom 3 of the water tank 1 captured by the strainer 30 The water W in the water tank 1 is sucked in such a manner that the gravel 6 is not sucked into the water suction pump 11 side, and dust 7 such as aquatic plants and feces is sucked in between the gravel 6.

そして、高さの低い水槽（例えば亀水槽）２の水Ｗを吸引する場合には、図５に示すように、吸水管路１６において、透明パイプ２５を使用せずに、ポンプ側ホース１７のパイプ側接続部２１に、直接、ノズル２９を接続させて使用する（図２のＢ参照）。この場合の使用時には、ノズル２９付近を把持して、高さの低い亀水槽２の底部３にノズル２９を向けて、亀水槽２内の水Ｗを吸引する。この作業は、透明パイプ２５が無いことから、ノズル２９付近を把持して、直接、ノズル２９の操作が行えて、作業を円滑に行うことができる。また、吸水を完了しようとしてノズル２９を水面から上げても、透明パイプ２５が無いことから、ノズル２９から亀水槽２の周壁部４における上端４ａ付近のポンプ側ホース１７の部位までの短い長さ分の水Ｗが亀水槽２内に戻るだけであり、水換えする水Ｗの量の割合を増加させることもできる。 And when sucking the water W of the low water tank (for example, turtle water tank) 2, as shown in FIG. 5, in the water absorption pipe line 16, without using the transparent pipe 25, the pump side hose 17 The nozzle 29 is directly connected to the pipe side connection portion 21 for use (see B in FIG. 2). In use in this case, the vicinity of the nozzle 29 is gripped, and the nozzle 29 is directed to the bottom 3 of the low turtle water tank 2 to suck the water W in the turtle water tank 2. Since there is no transparent pipe 25 in this operation, the vicinity of the nozzle 29 can be grasped and the nozzle 29 can be directly operated, so that the operation can be performed smoothly. Further, even if the nozzle 29 is lifted from the water surface in order to complete the water absorption, there is no transparent pipe 25. Therefore, the short length from the nozzle 29 to the pump-side hose 17 near the upper end 4a in the peripheral wall 4 of the turtle water tank 2 Only the water W of the minute returns to the turtle water tank 2, and the ratio of the amount of the water W to be changed can be increased.

さらに、砂利６の間のゴミ７を効率的に吸い込む場合には、図６と図２のＢの二点鎖線に示すように、吸水管路１６において、ポンプ側ホース１７のパイプ側接続部２１にノズル２９を接続し、そのノズル２９の先端部３１に透明パイプ２５を接続させて使用する。この場合の使用時には、透明パイプ２５の先端部２５ｂ側を下向きにして水槽１の底部３の砂利６の部位に差し込む等して、水槽１内の水Ｗを吸引すれば、水流の影響により、砂利６が、透明パイプ２５の下端側から侵入して上端側のノズル２９の部位まで（透明パイプ２５の長さ分）上昇し、その際、透明パイプ２５の内周面や砂利６相互で擦れて、砂利６の間に詰まっていたゴミ７や、砂利６に付着していたゴミ７を剥離させて、効率的にゴミ７を吸い込むことができる。勿論、透明パイプ２５の上端側には、ゴミ７を通過させて砂利６を捕捉するためのストレーナ３０を有したノズル２９が配設されており、砂利６や魚を吸水ポンプ１１側に通過させないことから、吸水ポンプ１１の弁等の故障や魚の傷付けを防止できる。 Further, when the dust 7 between the gravel 6 is efficiently sucked, the pipe-side connecting portion 21 of the pump-side hose 17 in the water-absorbing conduit 16 as shown by the two-dot chain line in FIGS. 6 and 2B. The nozzle 29 is connected to the nozzle 29, and the transparent pipe 25 is connected to the tip 31 of the nozzle 29 for use. At the time of use in this case, if the water W in the aquarium 1 is sucked by inserting the gravel 6 in the bottom 3 of the aquarium 1 with the tip 25b side of the transparent pipe 25 facing downward, The gravel 6 enters from the lower end side of the transparent pipe 25 and rises to the position of the nozzle 29 on the upper end side (the length of the transparent pipe 25). At that time, the gravel 6 rubs against the inner peripheral surface of the transparent pipe 25 and the gravel 6 with each other. Thus, the dust 7 clogged between the gravel 6 and the dust 7 adhering to the gravel 6 are peeled off, and the dust 7 can be sucked in efficiently. Of course, on the upper end side of the transparent pipe 25, a nozzle 29 having a strainer 30 for passing the dust 7 and capturing the gravel 6 is disposed, and the gravel 6 and the fish are not passed to the water absorption pump 11 side. Therefore, failure of the valve of the water absorption pump 11 and damage to the fish can be prevented.

したがって、実施形態の水槽用ポンプ１０では、水Ｗの入れ換え時等において、深さを異ならせた水槽１や亀水槽２等に容易に対処できて、ゴミ７取りも効率的に行うことができる。 Therefore, in the water tank pump 10 of the embodiment, when the water W is replaced, the water tank 1 and the turtle water tank 2 with different depths can be easily dealt with, and the dust 7 can be removed efficiently. .

また、実施形態の水槽用ポンプ１０では、ポンプ側ホース１７のパイプ側接続部２１における先側筒部２２や奥側筒部２３、透明パイプ２５、及び、ノズル２９の先端部３１や元部３２の大径筒部３３、小径筒部３４が、所定の内径寸法（Ｈ１、Ｈ２、Ｐｄ、及び、Ｎｄ）と外径寸法（ＰＤ、ＮＤ１、及び、ＮＤ２）としている。そして、ポンプ側ホース１７のパイプ側接続部２１を透明パイプ２５と接続させる場合には、先側筒部２２に透明パイプ２５を挿入嵌合させて行い、パイプ側接続部２１をノズル２９と接続させる場合には、奥側筒部２３にノズル２９の小径筒部３４を挿入嵌合させ、かつ、先側筒部２２にノズル２９の大径筒部３３を挿入嵌合させて行う。そして、これらの嵌合時に、固定リング３８をパイプ側接続部２１における先側筒部２２の外周側に嵌めれば、先側筒部２２が透明パイプ２５やノズル２９の大径筒部３３に押し付けられて、シール性良く、接続させることができる。 Further, in the aquarium pump 10 of the embodiment, the tip side cylinder part 22 and the back side cylinder part 23 in the pipe side connection part 21 of the pump side hose 17, the transparent pipe 25, and the tip part 31 and the base part 32 of the nozzle 29. The large-diameter cylindrical portion 33 and the small-diameter cylindrical portion 34 have predetermined inner diameter dimensions (H1, H2, Pd, and Nd) and outer diameter dimensions (PD, ND1, and ND2). And when connecting the pipe side connection part 21 of the pump side hose 17 with the transparent pipe 25, it inserts and fits the transparent pipe 25 in the front side cylinder part 22, and connects the pipe side connection part 21 with the nozzle 29. In this case, the small diameter cylindrical portion 34 of the nozzle 29 is inserted and fitted into the back side cylindrical portion 23, and the large diameter cylindrical portion 33 of the nozzle 29 is inserted and fitted into the front side cylindrical portion 22. At the time of these fittings, if the fixing ring 38 is fitted on the outer peripheral side of the front side cylinder part 22 in the pipe side connection part 21, the front side cylinder part 22 becomes the transparent pipe 25 or the large diameter cylinder part 33 of the nozzle 29. It is pressed and can be connected with good sealing performance.

また、このような構成では、浅い亀水槽２に使用する際において、ポンプ側ホース１７のパイプ側接続部２１に、ノズル２９を接続させる際、相互の嵌合部位は、奥側筒部２３に小径筒部３４が挿入嵌合され、かつ、先側筒部２２に大径筒部３３が挿入嵌合されて、ある程度の長さの剛性部位となって、浅い亀水槽２の水Ｗを吸引する際のノズル２９の操作時、ノズル２９の先端部３１側を水Ｗの中に入れて、嵌合部位近傍の付近のポンプ側ホース１７の部位を水面上で把持して、手を水の中に入れずに、ノズル２９を操作することができる。 In such a configuration, when the nozzle 29 is connected to the pipe-side connecting portion 21 of the pump-side hose 17 when used in the shallow turtle water tank 2, the mutual fitting portion is connected to the back-side cylindrical portion 23. The small-diameter cylindrical portion 34 is inserted and fitted, and the large-diameter cylindrical portion 33 is inserted and fitted into the front-side cylindrical portion 22 to form a rigid portion of a certain length, and suck the water W in the shallow turtle water tank 2. When the nozzle 29 is operated, the tip 31 side of the nozzle 29 is placed in the water W, the part of the pump side hose 17 near the fitting part is gripped on the water surface, and the hand is The nozzle 29 can be operated without being put inside.

また、図１と図７に示すように、透明パイプ２５の外周に吸盤４０を配設させておけば、吸盤４０の吸着部４０ａを水槽１の内周面４ｂに吸着させて、透明パイプ２５を水槽１に固定しておくことができて、透明パイプ２５から手を離して、吸水ポンプ１１等の操作や掃除を行うことができる。 Further, as shown in FIGS. 1 and 7, if the suction cup 40 is disposed on the outer periphery of the transparent pipe 25, the suction portion 40 a of the suction cup 40 is absorbed on the inner peripheral surface 4 b of the water tank 1, and the transparent pipe 25. Can be fixed to the water tank 1 and the hand can be released from the transparent pipe 25 to operate or clean the water absorption pump 11 or the like.

さらに、実施形態では、図８に示すように、流量調整器４２の挿通孔４３における所定の穴部（大開口部４４、中開口部４５、及び、小開口部４６）に、ポンプ側ホース１７の流量調整部２０を配置させれば、開口面積を大、中、小と変化させるように流量調整部２０を曲げることができて、流量を調整して水Ｗを吸い込むことができ、水の減りに応じて清掃や魚を採る等の作業を効率的に行うことができる。勿論、ポンプ側ホース１７の流量調整部２０自体を摘んで閉じれば、水Ｗの吸い込み自体を中断できて、透明パイプ２５や吸水ポンプ１１側への細かい砂や魚等の侵入を緊急停止できる。 Furthermore, in the embodiment, as shown in FIG. 8, the pump-side hose 17 is disposed in predetermined holes (the large opening 44, the middle opening 45, and the small opening 46) in the insertion hole 43 of the flow rate regulator 42. If the flow rate adjusting unit 20 is arranged, the flow rate adjusting unit 20 can be bent so that the opening area is changed to large, medium, and small, and the water W can be sucked in by adjusting the flow rate. Work such as cleaning and picking fish can be performed efficiently according to the decrease. Of course, if the flow rate adjusting unit 20 itself of the pump-side hose 17 is picked and closed, the suction of the water W itself can be interrupted, and the intrusion of fine sand or fish into the transparent pipe 25 or the water-absorbing pump 11 can be stopped urgently.

なお、実施形態の水槽用ポンプ１０の場合、ノズル２９の長さＬ１を約６ｃｍとして、透明パイプ２５の長さＬ２を、高さを３０ｃｍ以下とした水槽１用とするように、ノズル２９の長さ寸法の４倍程度の約２５ｃｍとしているが、３５〜５０ｃｍの高さの水槽の水の入れ換え等をする水槽用ポンプの場合には、長さＬ２を３０〜４５ｃｍ程度に長くした透明パイプ２５を準備しておけばよい。また、そのような高い高さの水槽に対応させた水槽用ポンプとする場合には、ノズル２９、透明パイプ２５、ポンプ側ホース１７、及び、蛇腹ホース１４は、排水量を向上させるように、適宜、内径寸法を大きくすればよい。 In the case of the aquarium pump 10 of the embodiment, the length L1 of the nozzle 29 is about 6 cm, and the length L2 of the transparent pipe 25 is used for the aquarium 1 with a height of 30 cm or less. A transparent pipe whose length L2 is about 30 to 45 cm in the case of an aquarium pump that replaces the water in an aquarium with a height of 35 to 50 cm. Prepare 25. Moreover, when it is set as the tank pump corresponding to such a high water tank, the nozzle 29, the transparent pipe 25, the pump side hose 17, and the bellows hose 14 are suitably used so that the amount of drainage may be improved. The inner diameter may be increased.
