PROBLEM TO BE SOLVED: To provide drawn water controlling structure for a plant pot with which environment around the plant pot may be kept clean, no bacteria and mosquitoes are generated, and in which a water filter is arranged in a detachable manner, thus stained water filter may be reused after washing.SOLUTION: A bowl unit 1 comprises: an inner bowl 10 having a recessed storage region 13 an outer bowl 11 supporting the inner bowl 10 a space section 12 created between the inner bowl 10 and the outer bowl 11 and a water gate hole 14 communicating the storage region 13 and the space section 12. A water stopper 7 is arranged at a contacting position between the inner bowl 10 and the outer bowl 11. A passage 20 having a hollow shape is formed in inner section of a tube 2. An air entering end 201 of the passage 20 is communicated with outer section of the space section 12 of the bowl unit 1. An exhausting end 202 of the passage 20 is communicated with inner section of the space section 12 of the bowl unit 1. In inner section of a water drawing unit 6, several small micro passages 601, 611 are formed.本發明包括有一盆體單元,其係由一具凹陷狀容置區域的內盆體、一支撐內盆體用的外盆體、一夾置於外盆體與內盆體之間的中空狀空間區、以及可由容置區域連通至空間區的滲水孔;其中:內盆體及外盆體的接觸位置間組設有止漏元件而致使其呈密閉狀,且滲水孔處安裝組設有引水過濾組件;該引水過濾組件包括有滲水件及濾水件,其中,滲水件及濾水件內部均形成有若干個不規則細小的微孔道,且滲水件係緊鄰接觸於濾水件上表面,並使滲水件的硬度較濾水件的硬度為硬者。10‧‧‧內盆體11‧‧‧外盆體12‧‧‧空間區13‧‧‧容置區域14‧‧‧滲水孔4‧‧‧土壤6‧‧‧引水過濾組件60‧‧‧滲水件601‧‧‧微孔道61‧‧‧濾水件611‧‧‧微孔道
