< Topic >Making use of the buoyancy of the blowhole which is generated by the air-supplied pump, the water wraparound die admiration service water vessel whose it is possible to wrap the water inside the tank securely, is offered.SolutionsThe tank itself 10 and air supplying and water flow tube 20 and air-supplied pump 30 and, the water wraparound die admiration service water vessel 1 which consists of, the tank itself base has 12 and wall surface 14 and possesses necessary height and the upper part aperture, forms by the transparency or the translucent material. Air supplying and the water flow tube as it has the hollow path 22 which, is penetrated completely from the top to the bottom possessing the height which the reduction is done longer than height of the tank itself, form by the transparency or the translucent material, the air-supplied pump, air-supplied tube 34 of necessary length being jointed by, pump body become, as in the plane view approximately center place in main internal of the tank, the bottom air supplying and the water flow tube stand facilities does when it is water flow possible, the Tip of the air-supplied tube in the air-supplied pump is laid out in base approximately center place of the tank itself.< Choice figure >Drawing 1【課題】送気ポンプにより発生した気泡の浮力を利用して、水槽内の水を確実に循環させることが可能な水循環型観賞用水槽を提供する。【解決手段】水槽本体10と、送気兼通水管20と、送気ポンプ30と、から成る水循環型観賞用水槽1であって、水槽本体は、底面12及び壁面14を備え所要高さを有して上方が開口されて透明若しくは半透明素材により成形される。送気兼通水管は、上端から下端まで貫通した中空路22を備えると共に水槽本体の高さよりも縮長した高さを有して透明若しくは半透明素材により成形され、送気ポンプは、ポンプ本体に所要長さの送気チューブ34が接続されて成り、水槽本体内における平面視略中央箇所に、下端部が通水可能な状態で送気兼通水管を立設すると共に、送気ポンプにおける送気チューブの先端が水槽本体の底面略中央箇所に配置される。【選択図】図1
