相关技术中，暖通空调通常安装有循环泵，循环泵能够使得水在空调系统内周而复始地循环，克服环路的阻力损失，满足客户供暖需求。循环泵包括泵腔结构，泵腔结构由泵头、密封圈、屏蔽罩、前盖、定子总成等多个部件构成，传统的泵腔结构的装配合缝较多，密封结构复杂，装配效率低。
为了解决上述的至少一个技术问题，本申请提出一种泵腔结构，其密封结构简单，装配效率更高。
参照图1至图2，本申请实施例提供的一种泵腔结构100，包括泵头110、叶轮120、屏蔽罩130、转子140和定子150。泵头110的内部开设有第一腔室111，第一腔室111设置有敞口端112。当然，泵头110的外壁还设置有进水口115和出水口116，进水口115连通于第一腔室111沿轴向的一端，出水口116连通于第一腔室111沿径向的一端。叶轮120安装于第一腔室111内并能够在第一腔室111内转动，叶轮120转动时能够带动需要输送的水或是其他液体从进水口115进入第一腔室111，然后从出水口116排出第一腔室111。屏蔽罩130罩设于敞口端112的外侧。转子140转动安装于屏蔽罩130的内部，并且转子140与叶轮120连接，因此转子140转动时能够带动叶轮120转动。定子150固定设置于屏蔽罩130的外部，且定子150绕设于转子140的外侧。其中，泵头110安装有绕设于敞口端112的外周的密封件160，密封件160呈环形状。屏蔽罩130朝向泵头110的一端设置有沿径向向外延伸的外沿部131，外沿部131的位置与密封件160相对应。安装时，将定子150通过螺栓等连接件152连接于泵头110，此时定子150的端部抵接于外沿部131背离密封件160的一端，从而使得外沿部131能够压紧于密封件160上，实现泵头110与定子150之间的密封连接。具体的，密封件160可以为硅胶或是橡胶等弹性材料制成，其受压时能够产生形变从而紧贴在外沿部131和泵头110之间，从而能够防止液体从敞口端112进入定子150内。连接件152可以设置有多个，多个连接件152沿定子150的周向间隔分布，从而使得密封件160的受力分布更为均匀，有利于提高密封件160的密封效果。
参照图2，该泵腔结构100通过在敞口端112外周安装密封件160，定子150连接于泵头110时能够抵接屏蔽罩130的外沿部131，从而使得外沿部131能够压紧密封件160，使得泵头110和定子150之间实现密封连接，防止第一腔室111内的液体进入定子150而造成定子150的损坏，该泵腔结构100能够以一个密封件160即可实现泵头110与定子150之间的密封，密封结构更为简单，有利于降低密封失效的风险，而且零部件数量更少，有利于降低装配的难度，提高装配的效率，同时有利于降低生产制造的成本，提高产品的竞争力。
参照图2和图5，需要说明的是，为了使得密封件160能够稳固地安装于泵头110上，在本申请的一些实施例中，敞口端112的外周设置有第一台阶位113，密封件160安装于第一台阶位113。具体的，第一台阶位113相对于泵头110的端面下沉，密封件160安装于第一台阶位113时能够受到第一台阶位113的侧壁对其的限位，从而能够防止密封件160在泵头110上容易晃动，提高密封件160安装的稳固性。当然，密封件160安装于第一台阶位113时，屏蔽罩130的外沿部131压紧于密封件160背离泵头110的一端，使得密封件160受压变形而紧贴于第一台阶位113的侧壁，从而能够提高密封件160与泵头110的接触面积，有利于提高泵头110与定子150之间的密封效果。
参照图2和图5，可以理解的是，为了使得定子150安装于泵头110上不易晃动，在本申请的一些实施例中，第一台阶位113的外周还设置有第二台阶位114，定子150设置有抵接于第二台阶位114的凸起部151。具体的，第二台阶位114相对于泵头110的端面下沉，并与第一台阶位113具有高度差。安装时，凸起部151抵接于第二台阶位114内，第二台阶位114的侧壁能够对凸起部151进行限位，从而防止定子150晃动。而且安装时，密封件160的外侧壁能够抵接于凸起部151的外侧壁，从而可以进一步提高密封件160的与定子150的接触面积，有利于提高密封件160的密封效果。
参照图1和图4，需要说明的是，为了便于安装定子150，在本申请的一些实施例中，屏蔽罩130连接有前盖170，前盖170与屏蔽罩130围设形成有第二腔室171，转子140包括转轴141和固定于转轴141的磁环142，磁环142位于第二腔室171内，转轴141伸出于第二腔室171与叶轮120连接。磁环142的外壁与第二腔室171的内壁之间具有间隙，因此磁环142能够在第二腔室171内顺畅地转动，从而带动转轴141转动。
参照图4，需要说明的是，为了使得转轴141转动时能够得到良好的回转支撑，在本申请的一些实施例中，第二腔室171沿轴向的两端分别布置有第一轴承180和第二轴承190，第一轴承180和第二轴承190分别套接于转轴141的两端，且第一轴承180和第二轴承190位于磁环142沿轴向的两侧，转轴141通过第一轴承180和第二轴承190能够实现稳定地转动。
参照图4，为了降低转轴141和第一轴承180以及第二轴承190之间的摩擦力，在本申请的一些实施例中，第一轴承180设置轴向贯通的第一通孔181，第二轴承190设置有轴向贯通的第二通孔191，转轴141设置有轴向贯通的穿孔145，前盖170设置有与第一腔室111连通的开口，从而在第一腔室111和第二腔室171之间形成液体的连通环路。转轴141带动叶轮120转动时，第一腔室111中的部分液体通过转轴141的穿孔145进入第二腔室171的一端，然后通过第一通孔181和第二通孔191进入第二腔室171的另一端，最后从前盖170的开口回流至第一腔室111。液体在连通环路循环内循环时，有利于在转轴141和第一轴承180的接触面之间以及转轴141和第二轴承190的接触面之间形成水膜，从而能够减少转轴141与第一轴承180以及第二轴承190的摩擦力，减少摩擦损耗，同时液体流动时，能够带走热量，从而能够降低摩擦导致的温升，有利于提高泵腔结构100的使用寿命。
当然，第一通孔181可以设置有多个，多个第一通孔181沿第一轴承180的周向间隔分布，从而有利于提高液体在第一腔室111和第二腔室171之间流通的顺畅性。相应的，第二通孔191也可以设置有多个，多个第二通孔191沿第二轴承190的周向间隔分布，有利于液体在第一腔室111和第二腔室171之间的流动。
参照图4，可以理解的是，为了能够稳固地安装第一轴承180和第二轴承190，在本申请的一些实施例中，第一轴承180安装于屏蔽罩130，第二轴承190安装于前盖170，此时第二通孔191能够通过前盖170的开口连通第一腔室111。具体的，屏蔽罩130远离泵头110的一端内凹形成有第一安装位，第一轴承180固定于第一安装位上。前盖170靠近泵头110的一端内凹形成有第二安装位，第二轴承190固定于第二安装位上，从而使得第一轴承180和第二轴承190均能够实现稳固地安装。
参照图4，需要说明的是，为了能够方便地对转子140进行维护，可以在屏蔽罩130设置有通孔，通孔的位置正对于转轴141的端部，通孔安装有密封螺栓132，从而可以防止液体从通孔流出。当转子140出现卡死等状况需要维护时，可以通过将密封螺栓132拆卸下来，然后将工具从通孔内伸入第二腔室171内，从而带动转轴141转动，解决转子140卡死的问题。通过上述设置，可以避免拆卸其他相关的部件，提高维护的便利性。
参照图3、图6和图7，可以理解的是，为了便于将叶轮120安装在转轴141上，在本申请的一些实施例中，转轴141的一端设置有扁位段143，扁位段143的径向厚度相对转轴141主体的厚度小，叶轮120设置有供扁位段143插接的扁孔121。安装时，将叶轮120的扁孔121对准转轴141的扁位段143，然后将叶轮120套接于转轴141，从而使得扁位段143插接于扁孔121内，扁位段143能够对叶轮120进行周向的限位，从而将叶轮120安装于转轴141上。
参照图3，需要说明的是，为了能够对叶轮120进一步限位，防止叶轮120沿轴向移动，在本申请的一些实施例中，扁位段143的外壁还设置有限位槽144，扁孔121的内壁设置有与定位槽匹配的限位筋122，限位筋122具有一定的弹性。转轴141的扁位段143插接于叶轮120的扁孔121时，限位筋122卡接于限位槽144内，从而可以防止叶轮120沿轴向移动，提高叶轮120安装于转轴141的稳固性。具体的，限位槽144呈环形状，限位筋122也可以是环形状，从而可以提高限位的效果。
参照图7，需要说明的是，在本申请的一些实施例中，为了进一步减少零部件的数量，降低装配的复杂性，制作转子140时，通过包塑工艺将转轴141和磁环142一体注塑成型，从而使得转子140的结构更为简单，装配效率更高。
相关技术中，传统的泵腔结构的定子总成装配于壳体中，定子总成的中部设置有屏蔽罩，转子安装于屏蔽罩内腔，壳体与屏蔽罩之间设置有排水槽，从而避免冷凝水或水蒸气浸入甚至积压于定子导电部分。为此，在本申请的一些实施例中，定子150为包塑定子，从而使得定子150的防水性能更好，降低定子150的导电部分浸水的风险，而且无需设置排水结构，降低制造成本，同时能够进一步减少零部件的数量，提高装配的效率。

参照图9至图11，本申请实施例还提供的一种电控总成100，应用于循环泵，电控总成100包括盒体120、盒盖110和电控板130，盒盖110安装于盒体120的一端并与盒体120围设形成安装腔。电控板130设置于安装腔内。盒体120设置有第一导电插片121、第二导电插片122和第三导电插片128，第一导电插片121、第二导电插片122和第三导电插片128与盒体120一体成型。第一导电插片121用于将电控板130与外部电源线导通，第二导电插片122用于将电控板130与电机200导通，第三导电插片128用于将电控板130与外部电控信号线导通。具体的，盒体120由塑料制成，第一导电插片121的导电部分为金属片，加工时可以通过模具固定金属片，然后将塑料注塑于金属片的外周，从而使得第一导电插片121和盒体120能够实现一体成型。类似的，第二导电插片122和第三导电插片128的导电部分也是金属片，加工时也可以通过模具将金属片固定，然后将塑料注塑于金属片的外周，使得第二导电插片122、第三导电插片128和盒体120能够实现一体成型。由于第三导电插片128通过的电流比第一导电插片121通过的电流小很多，因此第三导电插片128的截面积可以做得比第一导电插片121小，从而减少材料的成本。需要说明的是，当第一导电插片121、第二导电插片122和第三导电插片128通过模具固定时，其定位精度更高，从而能够使得第一导电插片121、第二导电插片122和第三导电插片128的位置精度更高，有利于提高接线的效率。
参照图11，该电控总成100通过将第一导电插片121、第二导电插片122和第三导电插片128与盒体120一体成型，从而能够减少电控总成100的零部件数量，减少装配工序，降低装配的难度，提高装配的效率，降低制造成本，而且将第一导电插片121、第二导电插片122和第三导电插片128与盒体120一体成型，使得第一导电插片121、第二导电插片122和第三导电插片128与盒体120的连接更为可靠，有利于提高第一导电插片121、第二导电插片122和第三导电插片128的导电连接的可靠性，同时能够提高第一导电插片121、第二导电插片122和第三导电插片128的防水防尘性能，进一步提高电控总成100的可靠性。
参照图11和图13，可以理解的是，电控总成100通常设置有用于连接外部电源线的线束140，线束140设置于盒体120的外壁并与第一导电插片121连接，而电机200通常安装于盒体120沿轴向的一侧，外部电控信号线靠近于盒体的侧壁，因此为了便于第一导电插片121连接线束140，同时便于第二导电插片122连接电机200以及便于第三导电插片128连接外部电控信号线，在本申请的一些实施例中，第一导电插片121和第三导电插片128固定设置于盒体120的侧壁，第二导电插片122固定设置于盒体120的底壁，从而使得第一导电插片121与线束140之间的距离更短、连接更方便，同时第二导电插片122与电机200的距离更短、连接更方便。具体的，第一导电插片121和线束140可以采用插接的方式进行连接，当然，第二导电插片122以及第三导电插片128也可以采用插接的方式与相应的部件连接，连接操作方便。

参照图11和图12，需要说明的是，上述的实施例中，卡扣123可以设置有多个，卡孔111也相应设置有多个，多个卡扣123周向间隔分布于盒体120的周壁，从而使得盒盖110与盒体120之间的连接受力分布更为均匀，连接更稳定、可靠。具体的，盒盖110大致呈四方形结构，盒盖110的每个侧边均设置有一个卡孔111，相应的，盒体120也具有四个卡扣123，安装时，每个卡扣123卡接于相应的卡孔111内，从而使得盒盖110稳固地连接于盒体120。
参照图9至图11，可以理解的是，为了进一步提高盒盖110与盒体120的连接可靠性，在本申请的一些实施例中，盒盖110还可以设置有连接孔112，盒体120设置有配合孔124，盒盖110能够通过螺栓等连接件150穿设于连接孔112和配合孔124而连接于盒体120，从而可以进一步提高盒体120和盒盖110连接的可靠性。具体的，连接孔112可以为沉孔，从而能够避免螺栓凸出于盒盖110的外部，防止外物碰触螺栓而影响连接的可靠性。
参照图10和图13，需要说明的是，在本申请的一些实施例中，盒体120连接于电机200的端部，为了使得电机200转轴210在卡死的时候，能够快速对其进行维修，本申请的盒体120对应电机200的转轴210设置有避让通道125，盒盖110对应避让通道125设置有避让孔113。当需要对转子进行维护时，可以打开电机200壳体对应转轴210的密封螺栓220，从而使得维修人员可以将工具经过避让孔113和避让通道125而伸入电机200壳体内，以对电机200进行维护，例如可以通过螺丝刀转动转轴210，以解决转轴210卡死的问题，或者可以通过螺丝刀打开密封螺栓220，以实现电机200内部的排水或排气。通过如上设置，可以在需要对电机200进行维护时，避免将电控盒从电机200上拆卸下来，提高维护的便利性和快捷性。
参照图12，上述实施例中，连接孔112可以设置有多个，多个连接孔112绕避让孔113的外周间隔设置，配合孔124也相应设置有多个，从而可以进一步提高盒体120和盒盖110连接的可靠性。
参照图12，可以理解的是，电控总成100在运行时会产生较多的热量，为了提高电控总成100的散热效果，在本申请的一些实施例中，电控总成100还包括有散热片114，散热片114由金属片制成，例如可以是铝片或者铜片，其具有较好的导热性能，同时散热片114具有较大的表面积，因此能够将从电子部件上吸收的热量通过与空气进行热交换而进行散热，从而有利于提高电子部件的散热效果，降低电子部件的温度，有利于提高电子部件的使用寿命。具体的，散热片114连接于盒盖110的内壁，从而使得散热片114能够与电控板130的距离更为接近，从而可以更好的吸收电控板130上的电子部件的热量。
参照图12，可以理解的是，为了使得散热片114能够稳固地安装于盒盖110，在本申请的一些实施例中，散热片114与盒盖110一体成型。具体的，盒盖110为塑料制成，制作时，将散热片114通过模具固定，然后将塑料注塑于散热片114的外周，使得散热片114能够与盒盖110实现一体成型。
参照图8，需要说明的是，在本申请的一些实施例中，电机200安装于盒体120的一端，为了方便安装，盒体120的外壁设置有定位柱126，定位柱126用于定位电机200。具体的，电机200的外壁设置有与定位柱126匹配的定位槽230，装配电控总成100与电机200时，定位柱126能够伸入于定位槽230内，从而能够实现装配导向和错位防呆的作用，有利于提高安装的便利性。
参照图10和图11，可以理解的是，为了将电控板130稳固地安装在安装腔内，在本申请的一些实施例中，盒体120的侧壁上端设置有台阶位127，台阶位127相对侧壁的外缘下沉，安装电控板130时，将电控板130的外缘的下端搭接于台阶位127上，从而使得台阶位127能够对电控板130进行支撑。当然，台阶位127可以沿着盒体120的周向设置，从而使得台阶位127的长度更长，从而能够对电控板130进行更为充分的支撑，进一步提高电控板130安装的稳固性。当然，盒盖110安装于盒体120时，盒盖110的下沿能够抵接于电控板130的外缘的上端，从而使得盒盖110能够对电控板130进行进一步地限位，防止电控板130晃动，进一步提高电控板130安装的稳固性。
参照图10和图11，需要说明的是，盒体120设置有空心柱，空心柱的内部形成避让通道125，多个配合孔124绕设于空心柱的外周。电控板130的中部为通孔，空心柱穿设于电控板130的中部，空心柱可以限制电控板130沿空心柱径向的移动，从而有利于进一步提高电控板130安装的稳固性，防止电控板130在安装腔内晃动。
