图 2是本发明滤水器的实施例一的结构示意图；
图 3是本发明滤水器的实施例二的结构示意图；
图 4是本发明滤水器的实施例三的结构示意图；
图 5是本发明滤水器的实施例四的结构示意图；
图 6是本发明滤水器的实施例五的结构示意图。 具体实施方式
如图 1所示， 本发明可自动清洁过滤棉的滤水器 2可以设在鱼缸或鱼池 1 的 底部， 也可以设在鱼缸或鱼池 1的顶部。
如图 2所示， 滤水器 2包括有一外壳体 20， 外壳体 20在其一端设有一可开 启的端盖 23， 并在端盖 23上设有一个能够与鱼缸或鱼池 1 相连通的进水口 33。 外壳体 20在其内部设有一滚筒 21， 滚筒 21在其侧壁上设有多个滤孔 34， 同时， 在其内部设有能够滤除水中杂质的过滤棉 22。 滚筒 21在其一侧壁的中间固定设置 有一轴杆 35， 轴杆 35架设在嵌设于外壳体 20壁上的轴承 26中， 并在轴承 26内 侧嵌设一防水密封圈 25。 轴杆 35与设在外壳体 20后侧方的马达 27和减速齿轮组 28相联结， 并由马达 27和减速齿轮组 28带动， 从而进一步带动滚筒 21作类似于 洗衣机的滚动， 即可对设在滚筒 21内部的过滤棉 22进行清洗。
滚筒 21上也可设有活动盖， 以便取、 放过滤棉 22， 或者滚筒 21是封闭的， 里面己内置了永久性的过滤棉 22。 制作过滤棉 22的材料可以是棉、 布、 网、 或者 过滤海棉胶， 也可是空调机使用的滤网或滤线； 同时， 过滤棉 22可制成袋状， 在 袋内置入活性炭或加入活性炭的过滤棉棉芯。
滚筒 21在其与外壳体 20的内壁之间形成一流水管道 36， 并在外壳体 20的后 侧底部设有一出水口 24, 出水口 24与一抽水泵 30的进水口相连接， 而抽水泵 30 的出水口与一分流器 31相连接， 分流器 31 的一个出水口通过一个二次过滤器 32 及管道与鱼缸或鱼池 1 的底部相连通， 而另一出水口通过管道与外界的污水管道 相连通。
其中， 二次过滤器 32在其内部设有活性炭 37， 如图 4所示， 利用活性炭 37 对水中的有害物质进行进一步过滤、 清洁。
上述马达 27、 抽水泵 30和分流器 31均由设在外壳体 20后侧方的控制电路板 29来控制， 控制电路板 29中的电路由于均采用现有市售成熟产品， 在此不再加以 详细描述。
在使用本发明的滤水器 2时，首先将整个滤水器 2安装在鱼缸或鱼池 1的底部， 并将其进水口 33和两个出水口分别与鱼缸 1和外界的污水管道相连通。 在平吋对 鱼缸或鱼池 1 内部的水进行过滤、 清洁时， 只需打开抽水泵 30， 同时， 使分流器 31与鱼缸或鱼池 1底部相连通， 此时， 鱼缸或鱼池 1内部的水会通过进水口 33进 入到滚筒 21的内部， 利用过滤棉 22对水进行过滤， 此时过滤棉 22是禁止不动的， 使水中的杂质残留在过滤棉 22 内。 而过滤后较为清洁的水通过滚筒 21 侧壁上的 滤孔 34进入到流水管道 36内， 再经抽水泵 30、 分流器 31的作用使经过滤后较为 洁净的水重新回到鱼缸或鱼池 1内。
当滤水器 2内的过滤棉 22在长时间使用后， 其内部残留的污秽物质较多时， 就会失去过滤、 清洁功能， 因此需要定期对设在滚筒 21 内部的过滤棉 22进行清 洁或更换， 为了减少过滤棉 22的使用成本， 只要启动马达 27， 带动滚筒 21作类 似于洗衣机的转动， 对设在其内部的过滤棉 22进行清洗， 此时过滤棉 22 也是滚 动的， 将污渍杂物送入分流器 31， 此时改变分流器 31 的分流方向， 使经滚筒 21 清洗后产生的污水经分流器 31后进入到外界的污水管道内。
如图 3所示， 滤水器 2也可以在外壳体 20内侧设置一搅拌器 4， 搅拌器 4与 设在外壳体 20后侧方马达 27相联接， 并由马达 27带动其作搅拌动作， 从而对设 在外壳体 20内部的过滤棉 22进行清洗。 外壳体 20在其后侧方设有两个出水口 40 和 41， 其中， 一个出水口 40与一二次过滤器 32相连接， 二次过滤器 32在其另一 端通过抽水泵 30与鱼缸或鱼池 1的底部相连接。 另一个出水口 41通过开关阀 42 与外界污水管道相连通。
如图 4所示， 本发明中的滤水器 2也可以设置在鱼缸或鱼池 1的顶部， 为此， 滤水器 2的外壳体 20在其内部设置有一搅拌器 4， 搅拌器 4与设在外壳体 20前侧 方的马达 27相联接， 并由马达 27带动其作搅拌动作。 外壳体 20在其顶部设有一 可开启以便放入过滤棉 22的端盖 23， 在其一侧底部设有一进水口 44， 进水口 44 通过一抽水泵 30与鱼缸或鱼池 1相连通， 在其另一侧的顶部设有一出水口 43， 当 滤水器在过滤时出水口 43与一个二次过滤器 32相连通， 在清洁过滤棉 22时， 出 水口 43通过管道 45与外界的污水管道相连通。
如图 5和图 6所示， 本发明的滤水器 2还可设成直立式结构， 并且设在滤水 器外壳体 20内部的搅拌器 4可以直立式设置， 也可以是倒置设置， 其中， 搅拌器 4为扇叶形， 以便对过滤棉进行充分地搅拌， 并且采用这种直立式结构， 显得整个 滤水器的结构更加紧凑， 体积小。
综上所述， 本发明的滤水器不仅不需要人手清洗过滤棉， 而且也无需经常更 换过滤棉， 从而可以降低过滤棉的使用成本， 进一步降低养鱼成本。
