    • An auto-shut off system for a water treatment device is disclosed. The auto-shut off system comprising a casing defining a top edge and a bottom edge; the casing including an inlet configured to receive a water inflow proximate the top edge and an outlet for the water outflow proximate the bottom edge, the casing defining a hollow passage for the uni-directional flow of water under gravity from the inlet to the outlet; a base configured to be received and retained within the casing, the base including a bottom surface and one or more sidewalls extending upward therefrom to define a hollow cavity and forming a rim disposed in contact with the casing, the base further defining an opening at or proximate the bottom surface, the opening in fluid communication with the outlet; at least one water soluble tablet positioned within the hollow cavity and configured to extend above the rim; the water soluble tablet sized smaller than the hollow cavity to define a clearance passage between itself and the base; the clearance in fluid communication with the opening on the base; the water soluble tablet configured to dissolve after contact with a pre-determined quantity of water; and a plunger supported over the water soluble tablet and sized smaller than the casing to define a side channel such that water from the inlet flows via the side-channel to pass through the opening and out of the outlet; the plunger further configured to descend downwards and engage the base on dissolution of the water soluble tablet and close the fluid communication between the inlet and the outlet. A water treatment device having such an auto shut off system is also disclosed.
    • 公开了一种用于水处理装置的自动关闭系统。 所述自动关闭系统包括限定顶部边缘和底部边缘的壳体; 壳体包括被配置为接收靠近顶部边缘的水流入口和用于靠近底部边缘的水流出口的入口,壳体限定用于重力从入口到出口的水的单向流动的中空通道; 底座,其构造成被容纳并保持在所述壳体内,所述底座包括底表面和从其向上延伸的一个或多个侧壁,以限定中空空腔并形成与所述壳体接触设置的边缘, 靠近底面,开口与出口流体连通; 至少一个水溶性片剂定位在所述中空腔内并且构造成在所述边缘上方延伸; 所述水溶性片剂的尺寸小于所述中空腔体以限定其自身与所述基部之间的间隙通道; 与基座上的开口流体连通的间隙; 所述水溶性片剂在与预定量的水接触后配制成溶解; 以及柱塞,其支撑在所述水溶性片剂上并且尺寸小于所述壳体以限定侧通道,使得来自所述入口的水经由所述侧通道流过所述开口并离开所述出口; 所述柱塞进一步构造成在所述水溶性片剂的溶解下向下并接合所述基部,并且关闭所述入口和所述出口之间的流体连通。 还公开了一种具有这种自动关闭系统的水处理装置。
