| 摘要 |
Water purification apparatus is provided, particularly for use in tea or coffee brewing apparatus, comprising a first vessel (1) for holding water to be purified and a second vessel (3) containing purifying agent (2), such as activated charcoal/carbon and ion exchange resin. The first vessel (1) is positioned above and communicates with the second vessel (2). When the first vessel (1) is filled with water, the water flows through the purifying agent (2) in the second vessel (3) and out of an outlet (15) of the second vessel (3). The outlet (15) of the second vessel is positioned at such a height in relation to the purifying agent (2) that the agent (2) remains substantially submerged in water, even when the first vessel (1) subsequently empties. A preferred feature is that flow restrictor means (15) are provided for substantially restricting the rate of flow of water through the purifying agent (2). |
