Description

一种防水泵体 技术领域
本实用新型属于具有叶轮的负压泵领域，具体涉及一种防水泵体。
背景技术
泵是一种利用电机产生扭力，带动叶轮转动，产生负压的装置，它能将水、空气、油液等流体输送到需要的地方。泵的常见应用有抽水机、油烟机、旱地吸尘器、水下清洁机器人等。
在申请日为2019年12月30日，公开号为CN211648507U，专利名为“一种高效吸尘器风机总成及其吸尘器”的中国专利中就公开了一种高效吸尘器风机总成及其吸尘器，包括吸尘器电机和动叶轮，动叶轮通过导风圈与吸尘器电机的旋转轴固定安装连接，且动叶轮套设在叶轮罩的内周，叶轮罩壳体的内壁设有若干导流筋，导流筋沿叶轮罩壳体的内壁向其内侧方向一体延伸；动叶轮安装壳体上设有若干以进风口作为中心且向其外周呈环状间隔分布的若干叶片，至少1个叶片的外周端面设有相互连接的第一凸齿和第二凸齿，且第一凸齿和第二凸齿之间形成抗涡流凹槽；导风圈至少1个导风叶片的上表面和/或下表面设有与其呈垂直分布的分流叶片，分流叶片长度小于导风叶片长度，且分流叶片相对导风入口靠近导风出口一侧。
在以上专利对比文件中，吸尘器电机没有防水结构，动叶轮上的流体以及污垢容易甩到吸尘器电机上。
在申请日为2018年05月11日，公开号为CN208153389U，专利名为“水下清洁机器人泵水结构”的中国专利中就公开了水下清洁机器人泵水结构，包括壳体组件，壳体组件内部设有第一腔体和第二腔体，第一腔体的上方设有开口于壳体组件的排水口，第一腔体和第二腔体之间设有通道，第一腔体内固设有泵水装置，泵水装置包括朝向排水口的叶轮；第二腔体底部设有开口于壳体组件的吸污口，第二腔体中设有对接于吸污口的过滤装置。第二腔体的内壁与过滤装置之间设有间隙。叶轮与排水口之间设有涡流干扰装置。壳体组件包括垂直设置且套设于泵水装置外周的固定筒。

发明内容
本实用新型所要解决的技术问题是针对上述现有技术的现状，而提供防水性能好，叶轮转动时抖动小的一种防水泵体。
本实用新型解决上述技术问题所采用的技术方案为：一种防水泵体，包括

第一外壳和第二外壳之间设有可拆卸连接结构；
第一外壳设有第一台阶面，第二外壳设有第二台阶面，第一台阶面和第二台阶面彼此相对，并且共同夹在法兰支架上。
安装法兰支架时，先将法兰支架放入第一外壳内，然后将第二外壳装配到第一外壳上，直至第一台阶面和第二台阶面共同夹住法兰支架。
在优选的方案中，可拆卸连接结构为螺纹连接结构，第一外壳和第二外壳之间夹设有密封圈。
在优选的方案中，第一轴体与第一转盘为一体成型结构，轴承支架为套在第一轴承外圈的套筒状件。
在另一种方案中，扭力传动装置包括：
第三轴承，固定在隔水腔室内；
第三转盘，连接第二磁钢组；
第三轴体，设于第三轴承中，并且连接第三转盘和电机轴。

综上所述，与现有技术相比，本实用新型采取电机本体安装在隔水腔室内，将电机本体彻底与外界隔绝的方式来防止电机本体进水，从而克服了现有技术中外界液体容易从电机轴渗入电机内部的缺陷；此外将远离电机本体的叶轮固定在第一轴体上，通过第一轴承的定位和支撑，使叶轮转动时抖动小。

实施例一，如图1和图6所示：
一种防水泵体，包括
叶轮2；
电机本体7,设有电机轴71；
其中，还包括：
壳体1，内设有密封的隔水腔室15，电机本体7位于隔水腔室15内；
隔板112，位于隔水腔室15和叶轮2之间；
轴承支架111，位于壳体1上；
第一轴承3，位于叶轮2和隔板112之间，并固定于轴承支架111上；
第一轴体41，配设在第一轴承3中，朝向隔板112的一端设有第一转盘42，另一端连于叶轮2；
第一磁钢组51，位于第一转盘42上，第一磁钢组51是由中心对称排列的S极磁钢和N极磁钢构成，S极磁钢和N极磁钢彼此交错设置，S极和N极排列是现有技术，故图中未示出；第二磁钢组52，位于隔水腔室15内,并且磁力作用于第一磁钢组51，第二磁钢组52是由中心对称排列的S极磁钢和N极磁钢构成，S极磁钢和N极磁钢彼此交错设置。S极和N极排列是现有技术，故图中未示出。第一磁钢组51和第二磁钢组52能保持磁力作用，当第二磁钢组52转动时，第一磁钢组51跟随转动；
扭力传动装置6，传动连于第二磁钢与电机轴71之间。
当电机轴71转动时，带动扭力传动装置6，扭力传动装置6带动第二磁钢组52旋转，第二磁钢组52带动第一磁钢组51转动，第一磁钢组51同步带动第一转盘42、第一轴体41和叶轮2转动，作为动力源的电机本体7能够密封在隔水腔室15内，防止外界水渗入；由于第一轴体41安装在第一轴承3上，所以即使电机本体7和叶轮2之间的距离较远，也能避免叶轮2的抖动，若换成电机轴71直接连接叶轮2，则会因电机轴71过长产生叶轮2抖动。
实施例中，隔板112设有第二轴体113，第二轴体113凸出于隔水腔室15，并且和第一轴体41处于同一轴线上；
扭力传动装置6包括：
第二轴承61，套设在第二轴体113上；
第二转盘63，固定在电机轴71上；
磁钢支架62，固定在第二轴承61外圈，第二磁钢组52位于磁钢支架62上；
磁钢支架62和第二转盘63之间设有周向限位结构，周向限位结构能限制磁钢支架62和第二转盘63之间的周向相对转动。
实施例中，周向限位结构包括：
凹部631，位于第二转盘63上；
凸部621，位于磁钢支架62上。
凹部631和凸部621互相对位，当第二转盘63转动时能够带动磁钢支架62转动。
实施例中，第二轴体113的内部设有第一容纳腔114，第一容纳腔114开口朝向第一转盘42；
第一转盘42设有第二容纳腔421，第二容纳腔421正对第一容纳腔114。第一容纳腔114和第二容纳腔421能够存储润滑液。
实施例中，磁钢支架62为套设在第二轴承61的外圈的套筒状件。
实施例二，如图7所示：
实施例二与实施例一的不同之处在于周向限位结构的结构不同，实施例二的周向限位结构是固定连接第二转盘63和磁钢支架62的螺钉632。
实施例三，如图8、9、10：
实施例三是在实施例一的基础上，在隔水腔室15内设有法兰支架8，法兰支架8固定于电机本体7。法兰支架8方便电机本体7的定位，确保电机轴71和第一轴体41处在同一轴心上。
实施例中，壳体1包括：子母对接形成隔水腔室15的第一外壳11和第二外壳12；第一外壳11和第二外壳12之间设有可拆卸连接结构13；
第一外壳11设有第一台阶面115，第二外壳12设有第二台阶面121，第一台阶面115和第二台阶面121彼此相对，并且共同夹在法兰支架8上。
安装法兰支架8时，先将法兰支架8放入第一外壳11内，然后将第二外壳12装配到第一外壳11上，直至第一台阶面115和第二台阶面121共同夹住法兰支架8。
实施例中，可拆卸连接结构13为螺纹连接结构，第一外壳11和第二外壳12之间夹设有密封圈131。
实施例中，第一轴体41与第一转盘42为一体成型结构，轴承支架111为套在第一轴承3外圈的套筒状件。第一外壳11、隔板112和第二轴体113为一体成型结构。
实施例四：
实施例四与实施例一的不同之处在于可拆卸连接结构13的不同，实施例四的可拆卸连接结构13是通过胶水连接，溶解去除胶水后能再次使用胶水固连，由于这是公知技术所以图中没示出，仅仅为了支持可拆卸连接结构13这一上位概念作出的举例。
实施例五，如图11所示：
实施例五与实施例一的不同之处在于扭力传动装置6不同，并且没有第二轴体113，实施例例五的扭力传动装置6包括：
第三轴承65，固定在隔水腔室15内；
第三转盘64，连接第二磁钢组52；
第三轴体66，设于第三轴承65中，并且连接第三转盘64和电机轴71。
当电机轴71转动时，电机轴71带动第三轴体66转动，第三轴体66带动第三转盘64转动，从而使第二磁钢组52旋转。
实施例六，如图12和图13所示：
实施例六与实施例一的不同之处在于扭力传动装置6不同，并且没有第二轴体113，实施例例六的扭力传动装置6是固定连接于电机轴71和第二磁钢组52的轴体。当电机轴71工作时，电机轴71会同时带动第四轴体和第二磁钢组52转动。
以上所述，仅为本发明创造的具体实施方式，但本发明创造的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应所述以权利要求的保护范围为准。
