具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，若本申请实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请公开一种水泵，所述水泵用于作为输送液体（例如水、油、溶液、乳液等液态物质）的增压机械。所述水泵能够减少水泵堵塞的情况发生，延长水泵的使用寿命。
请参阅图1至图3，本申请的水泵100包括泵体110和多个立柱120；泵体110具有出水口102及与出水口102连通的进水口101；多个立柱120设置在泵体110上，并且，多个立柱120环绕进水口101。
具体说来，泵体110在其下表面设有进水口101，并在其上表面设有出水口102。多个立柱120设置在泵体110的下表面，且环绕进水口101。水泵100工作时，驱动液体从进水口101进入其内部，然后驱动这部分液体从出水口102流出。在进水过程中，液体从多个立柱120之间的间隙流向进水口101，而液体中的毛絮物则被缠绕在多个立柱120上，不易被水泵100吸入器内部。
多个立柱120可以沿一圆形环周环绕进水口101。当然，多个立柱120也可以沿方形环周环绕进水口101。具体可依据进水口101的形状及泵体110的形状，进行相应设计，在此不设限定。
本申请的技术方案，通过在水泵100上设置多个立柱120，多个立柱120呈环绕进水口101设置，以在水泵100进水过程中，利用多个立柱120将液体中的毛絮物缠绕，避免毛絮物被吸入到水泵100内部，进而减少水泵100堵塞的情况发生，延长水泵100的使用寿命。此外，由于毛絮物被缠绕在立柱120上，从而在清洁水泵100时，仅需将毛絮物从立柱120下拉出即可，简单易清洁。
请继续参阅图1至图3，在一实施例中，多个立柱120可以环绕进水口101一圈或者多圈均可。在此考虑到，如果多个立柱120仅环绕进水口101一圈时，有可能有部分毛絮物在水泵100的强大吸力下从该圈立柱120上脱落，而被吸入水泵100内部。因此，可适当增加多个立柱120环绕进水口101的圈数。
但是，所述圈数也不是越多越好，当圈数越多时，液体流的阻力就越大，进入水泵100的液体量就变小。因此，综合考虑为确保水泵100具有较佳的过滤效果和较大的进水量，可选地，多个立柱120可以环绕进水口101两圈或三圈。至于每圈立柱120的数量，仅需按照每圈立柱120的大小合理排布即可，在此不设具体限定。
至于立柱120的形状结构，则没有具体限定。立柱120可以呈圆柱状设置、或者呈多棱柱状设置、亦或者呈扁平片状设置。具体在此，多个立柱120呈圆柱状设置，如此可以减小立柱120对液体流的阻力，有利于液体从相邻立柱120之间的间隙通过并流向进水口101。
此外，鉴于毛絮物较轻，常漂浮在水面上。为提高水泵100的过滤效果，可选将立柱120的外径在其高度方向呈逐渐减小。这样可使得立柱120“上大下小”，立柱120的上端外径较大，较便于缠绕毛絮物。立柱120的下端外径较小，对水流阻力较小，便于水流通过。
在一实施例中，为了提高多个立柱120的过滤毛絮物的效果，将多个立柱120的端面平齐设置。假使有部分毛絮物从外围区域的立柱120脱落下来，那么再其向进水口101方向移动的过程中，最终也会被内围区域的立柱120缠绕，从而有效提高过滤效果。
请参阅图1至图3，在一实施例中，为便于水泵100驱动液体从进水口101进入，泵体110在进水口101的环周凸设有进水柱114。使用水泵100时，仅需水泵100的进水柱114保持在液面下即可抽取到液体。对于多个立柱120在泵体110上的具体位置，多个立柱120设置在进水柱114的端面上，和/或，多个立柱120环绕在进水柱114的外围。
也就是说，多个立柱120可以全部设置在进水柱114的端面上，以环绕在较为靠近进水口101的位置处。或者，多个立柱120也可以全部设置在进水柱114的外围，以环绕在进水口101的外围位置。亦或者，部分立柱120设置在进水柱114的端面上，其余部分立柱120环绕在进水柱114的外围。
具体在此，多个立柱120包括多个第一立柱120a和多个第二立柱120b。其中，第一立柱120a立柱120设置在进水柱114的端面上，第二立柱120b环绕在进水柱114的外围。由于第一立柱120a所在环周小于第二立柱120b所在环周，因此，第一立柱120a的数量小于第二立柱120b的数量。
请参阅图1至图3，在一实施例中，设置于进水柱114的外围的立柱120（即前述的第二立柱120b），与进水柱114的侧壁之间连接有连接筋130。连接筋130可以加强立柱120的强度，提高其稳定性。
请参阅图1至图3，在一实施例中，设置于进水柱114的外围的相邻的两个立柱120（即前述的第二立柱120b）之间连接有连接板140。连接板140不仅可以加强立柱120的强度，提高其稳定性。并且，连接板140还可以拦截漂浮于液面上的毛絮物，使其不能从第二立柱120b之间通过，进一步提高过滤效果。
基于此，为提高连接板140拦截毛絮物的效果，连接板140具有相邻的三个侧边，该三个侧边分别与相邻的立柱120及泵体110的表面连接。这样设计，可以确保连接板140将漂浮于液面上的毛絮物拦截在外圈的第二立柱120b之外。
请参阅图2至图4，理论上说来，连接板140在泵体110的表面上的高度越大，其拦截毛絮物的效果越明显。但是，也会因此减小立柱120之间的间隙，从而减少液体通过量。因而在本实施例中，限定连接板140在泵体110的表面上高度，不小于与该连接板140连接的立柱120的高度的1/5，且不大于该立柱120的高度的1/2。
具体地，假定连接板140在泵体110的表面上高度为H1, 与该连接板140连接的立柱120（即第二立柱120b）的高度H2。那么，H1和H2应当符合1/5H2≤ H1≤1/2 H2。例如但不局限于：H1=1/5H2、2/5H2、1/2 H2。这样设计，可使得连接板140具有较佳的拦截毛絮物效果，并可确保相邻的两个第二立柱120b之间具有足够的间隙供水流通过。
请参阅图2至图4，进一步地，为避免连接板140阻挡水流进入进水口101，可选地，连接板140在泵体110的表面上的高度，小于进水柱114在泵体110的同一表面上的高度。假定进水柱114在泵体110的同一表面上的高度为H3，那么H1和H3应当符合H1＜H3。
请参阅图1至图3，基于上述任意一实施例，泵体110包括座体111、盖体112及驱动桨叶113；所述座体111具有进水口101，以及将进水口101和出水口102连通的空腔103，所述盖体112盖合所述空腔103，所述驱动桨叶113贯穿所述盖体112而穿插于所述空腔103内。
具体地，进水口101开设在所述座体111的下表面，出水口102设置在所述盖体112的上表面。多个立柱120围绕进水口101设置。水泵100工作时，驱动所述桨叶旋转而将外部液体吸入到所述空腔103内，再从出水口102流出。
请参阅图5至图7，本申请还提供一种空调清洁装置200，所述空调清洁装置200包括集水盒210和水泵100，水泵100的出水口102与所述集水盒210连通，以向所述集水盒210供水。所述空调清洁装置200的具体结构参照上述实施例，由于本空调清洁装置200采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
请参阅图5和图6，所述空调清洁装置200用于清洗壁挂式室内机300的内部构件。所述内部构件可以是过滤网、换热器、或贯流风轮320等。在此具体以所述内部构件为过滤网为例进行解释说明。
请参阅图7至图9，在一实施例中，所述空调清洁装置200用于清洗过滤网330。所述空调清洁装置200还包括所述空调清洁装置200还包括第一滚刷220、第二滚刷230及驱动组件（未图示）；其中，所述第一滚刷220和所述第二滚刷230呈上下向设于所述集水盒210上，用以配合夹持过滤网；所述驱动组件与所述第一滚刷220及第二滚刷230连接。
具体地，所述集水盒210的上端形成有敞口，所述第一滚刷220安装于所述敞口，且至少部分浸入到集水盒210的水面下。所述第二滚刷230位于所述第一滚刷220的上侧，并与所述第一滚刷220配合夹持所述过滤网一端。所述驱动组件与所述第一滚刷220、第二滚刷230连接，以驱动所述第二滚刷230和所述第一滚刷220转动而带动所述过滤网移动。在此过程中，所述第二滚刷230和所述第一滚刷220配合将所述过滤网上的脏物刷落。
请参阅图7，在一实施例中，水泵100安装于所述集水盒210的底部。为便于水泵100与所述集水盒210连接，水泵100的泵体110的外表面侧向凸设有一对凸耳115，一对所述凸耳115与所述集水盒210连接。所述凸耳115与所述集水盒210可通过卡扣结构或者螺钉结构连接。在此具体地，所述凸耳115上开设有通孔，所述通孔通过螺钉与所述集水盒210连接。
请参阅图5至图7，本申请还提供一种壁挂式室内机300，所述壁挂式室内机300包括壳体310和空调清洁装置200，所述空调清洁装置200安装在所述壳体310内，用以清洗所述壁挂式室内机300的内部构件。所述空调清洁装置200的具体结构参照上述实施例，由于本壁挂式室内机300采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
请参阅图5至图7，所述壁挂式室内机300还包括贯流风轮320、换热器（未图示）及过滤网330。所述贯流风轮330和换热器安装在所述壳体310。所述壳体310设有进风口，所述进风口处安装有滤网格栅340，所述过滤网300安装在滤网格栅340上。
请参阅图5至图7，所述空调清洁装置200的水源可以是壁挂式室内机300的接水槽301内的冷凝水，也可以是壁挂式室内机300外部的水。在此为了提高水资源利用率，可选地，所述壳体310包括底盘311，所述底盘311设有接水槽301，所述空调清洁装置200的水泵100与所述接水槽301连通。所述接水槽301用以承接壁挂式室内机300的换热器产生的冷凝水，通过水泵100将这部分冷凝水抽取用于清洗过滤网，无需额外补充水源，提高了水资源利用率。
但是，所述壁挂式室内机300通常是安装在室内环境，其内部容易吸附毛发或纤维等毛絮物。这些毛絮物落在接水槽301内时，毛絮物随接水槽301的水一起进入水泵100内，容易堵塞空调清洁装置200的水泵100，或者在造成清洗内部构件的过程中造成二次污染。
鉴于此，为避免上述情况发生，将水泵100的多个立柱120伸入到所述接水槽301内。在水泵100进水的过程中，液体从多个立柱120之间的间隙流向进水口101，而液体中的毛絮物则被缠绕在多个立柱120上，不易被水泵100吸入其内部，从而避免水泵100堵塞或者清洗过程中二次污染的情况发生。
本申请还提供一种空调器，所述空调器包括空调室外机和壁挂式室内机，所述壁挂式室内机与所述空调室外机通过冷媒管连接。所述壁挂式室内机的具体结构参照上述实施例，由于本空调器采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
