Description

一种智能水泵
技术领域
本发明涉及水泵技术，尤其是涉及一种能够对水位进行判断并且 控制水泵工作的智能水泵。 背景技术
目前应市场需求， 各水泵厂开发了一种智能泵， 这种泵要求水位 在 1. 5英寸时就要抽水， 抽到 0. 25英寸为止。 因为目前通用的浮子 浮球比较重， 浮球池水深度大大超过 0. 25英寸， 所以一般来说浮子 不能用。各厂家都推出了一种带电控器的水泵， 这种泵利用了抽到水 和抽不到水时， 电机的转速不同， 来达到判断水泵有没有抽到水的依 据。 这种水泵有几个缺点， a， 即使没有水， 电机每隔一段时间都要 转动一次， 以此来检测是否可以抽到水。 b， 由于水泵的不一致性， 很多情况下， 会导致异常。 有水却不抽水， 或者无水却一直抽水。 由 于这些原因， 这种水泵正在被市场淘汰。 发明内容
本发明所要解决的技术问题是提供一种能够根据水位的不同自 动控制水泵工作与否的智能水泵。
本发明解决其技术问题所采取的技术方案是： 一种智能水泵， 包 括机壳、机壳顶部设有出线盒盖， 出线盒盖的上部设有插线头， 机壳 内设有电路板， 电路板的下方设有转子和定子， 机壳的下部设有电机 前端盖， 电机前端盖的下方设有涡壳， 涡壳内部设有叶轮， 叶轮与转 子共用一根转轴， 在机壳的一侧设有出水管道， 所述的机壳另一侧设 有水位感应装置。
为了能够判断水位， 并且更好的根据水位控制水泵， 所述的水位 感应装置包括感应器盒， 感应器盒上设有感应探针； 所述的感应探针 包括高水位探针、低水位探针和地探针， 它们的长度为高水位探针小 于低水位探针小于地探针。
为了过滤掉水中的杂质， 减少对水泵的损害， 所述的涡轮的下方 设有过滤网， 在机壳安装水位感应装置的下方设有小过滤网。
本发明的有益效果是： 采用了水位感应装置， 能够根据水位控制 水泵的转动，克服了目前各种水泵普遍出现的有水不抽水和无水抽水 的现象。 附图说明
图 1是本发明的结构示意图；
图 2是本发明水位感应装置的结构示意图。

15、 感应器盒 16、 高水位探针 17、 低水位探针 18、 地 探针 具体实施方式
下面结合附图对本发明进一步说明。
如图 1所示一种智能水泵， 包括机壳 5、 机壳顶部设有出线盒盖 13， 出线盒盖 13的上部设有插线头 1 , 机壳 5内设有电路板 2， 电路 板 2的下方设有转子 4和定子 6， 机壳 5的下部设有电机前端盖 7， 电机前端盖 7的下方设有涡壳 8， 涡壳 8内部设有叶轮 10， 叶轮 10 与转子 4共用一根转轴 3， 在机壳 5的一侧设有出水管道 14， 所述的 机壳 5另一侧设有水位感应装置 12; 所述的涡壳 8的下方设有过滤 网 9， 在机壳 5安装水位感应装置 12的下方设有小过滤网 11。
