The invention relates to a combination-closeness type hollow pot body structure for pot culture. The pot body structure at least comprises an internal pot body, an external pot body, an anti-leak element, a hollow conduit and a drainage weeping element. The internal pot body comprises a bottom surface and a side surface. The side surface surrounds the bottom surface around to define a concave containing region. The bottom surface is formed with an inward part, and the inward part is provided with a weeping hole thereon. The drainage weeping element, which is capable of being disposed on the inward part of the internal pot body so that one end of the drainage weeping element can penetrate through the weeping hole of the internal pot body and protrudedly extend to the other side of the weeping hole. The internal pot body further comprises a binding part that is formed at an appropriate site and located at a periphery of the containing region. The transparent external pot body is provided with a full-flow mark region comprises a connection part that is able to assemble on the binding part of the internal pot body. Accordingly, the anti-leak element can be tightly clamped between the internal pot body and the external pot body to form a hollow spatial region which is provided with a combination-closeness type upper region. Besides, the hollow conduit, which comprises one end capable of being inserted into the spatial region for communication, is utilized to provide air communication between the spatial region and the exterior of the spatial region.本發明至少包括有內盆體、外盆體、止漏元件、中空導管及引流滲水件所組成,其中,內盆體底面及其側面所環繞形成一凹陷狀容置區域,且內盆體的底面形成有內凹部,且於內凹部上形成有滲水孔,以供引流滲水件能置於內凹部上,且使引流滲水件的一端能穿過滲水孔而凸伸於另側;又,內盆體的適當處形成有結合部,且結合部係位於容置區域的外圍處,以供已具有溢滿標示區的透明狀外盆體之接合部能組設於內盆體之結合部上,以致使止漏元件能被緊密夾置於內盆體及外盆體之間而形成一具有組合密閉狀之上半段區域的中空狀空間區;另外,中空導管的一端係可插入連通至空間區內,以作為空間區與空間區外側的空氣連通之用。1...內盆體10...底面101...內凹部102...滲水孔11...側面115...環立面12...結合部13...容置區域2...外盆體22...接合部23...溢滿標示區3...止漏元件4...導管40...頂端41...底端
