    • A tree stand for supporting a tree includes a base. The base includes a receptacle for receiving and supporting the trunk of the tree. A fluid reservoir for storing a fluid is detachably connected to the base. A first valve is attached to the reservoir and is operable between and open and closed position to allow fluid to flow outwardly of the reservoir in the open position and to prevent fluid from flowing outwardly of the reservoir in the closed position. A second valve is attached to the base and is in fluid communication with the receptacle. The second valve is operable in an open position to allow fluid to flow into the receptacle, and a closed position to prevent fluid from flowing outwardly of the receptacle. The first and second valves are disposed such that when the fluid reservoir is attached to the base, the first valve engages the second valve to cause the first valve to move from the closed position to the open position and allow the second valve to move from the closed position to the open position thereby allowing fluid to flow from the fluid reservoir into the receptacle.
    • 一棵树支撑树包括一个基地。 基座包括用于接收和支撑树干的插座。 用于存储流体的流体储存器可拆卸地连接到基座。 第一阀连接到储存器并且可操作在开启位置和关闭位置之间,以允许流体在开启位置从储存器向外流动,并且防止流体在关闭位置从储存器的外部流出。 第二阀连接到基座并与容器流体连通。 第二阀可在打开位置操作以允许流体流入容器,以及关闭位置以防止流体从容器外部流出。 第一和第二阀设置成使得当流体储存器附接到基座时,第一阀接合第二阀,以使第一阀从关闭位置移动到打开位置,并允许第二阀从 关闭位置到打开位置,从而允许流体从流体储存器流入容器。
