The present invention relates to an unpowered automatic water supply device responding to a soil water content ratio change, the device comprising: a water tank having a water supply tube through which water is supplied from the outside a container support communicating with the interior of the water tank via a connection tube and a container in which flowers are planted, the container being seated on the upper portion of the container support, an injection opening being formed on the bottom surface of the container such that water flows in, wherein water flowing to the connection tube is adjusted and then supplied into the container through the injection opening. The supply of water to the container can be advantageously interrupted in response to the weight of soil contained inside the container.La présente invention concerne un dispositif automatique non électrique dalimentation en eau réagissant à une variation du rapport de la teneur en eau du sol, le dispositif comprenant : un réservoir deau doté dun tube dalimentation en eau à travers lequel est acheminée leau depuis lextérieur un support de contenant communiquant avec lintérieur du réservoir deau par le biais dun tube de raccordement et un contenant dans lequel sont plantées des fleurs, le contenant étant disposé sur la partie supérieure du support de contenant, une ouverture dinjection étant formée sur la surface inférieure du contenant de sorte que leau puisse sy écouler, leau sécoulant vers le tube de raccordement étant ajustée et ensuite acheminée à lintérieur du contenant par louverture dinjection. Lalimentation en eau du contenant peut être interrompue de manière avantageuse en réponse au poids du sol contenu à lintérieur du contenant.본 발명은 외부로부터 물이 공급되는 급수관이 구비되는 물통과, 상기 물통의 내부와 연결관을 통해 연통되는 용기받침과, 화초가 식재되어 용기받침의 상부에 안착되고 바닥면에 주입구가 형성되어 물이 유입되는 용기와, 상기 연결관으로 유입되는 물을 조절하여 주입구를 통해 용기의 내부로 급수하는 토양 함수율 변화에 대응하는 무동력 자동급수장치에 관한 것으로, 용기의 내부에 수용된 토양의 무게에 대응하여 용기로 급수되는 물을 차단하는 것이 가능한 효과가 있다.
