Description

管路连接装置 技术领域
本发明涉及管路连接技术领域，具体而言，涉及一种管路连接装置。
背景技术
在现有技术中，空调内机的排水管直接与下水管道相连，并且该下水管道也为生活废水的下水管道。因此，上述下水管道中会存在具有腐蚀性、臭味的气体。当空调开启瞬间形成的负压会将上述下水管道内的具有腐蚀性、臭味的气体吸入空调风道内，出现气体倒灌现象。这些气体会腐蚀蒸发器上的铜管，影响空调的使用寿命。同时，这些气体如果通过空调出风口进入空调房内，也会危害人体的健康。
发明内容
本发明的主要目的在于提供一种管路连接装置，以解决现有技术中的管路与下水管道连接时容易出现气体倒灌现象的问题。
为了实现上述目的，本发明提供了一种管路连接装置，包括：连接主体，具有上连接口和下连接口；第一通道和第二通道，设置在连接主体内，第二通道位于第一通道的下方，第一通道的上端与上连接口连通，第二通道的下端与下连接口连通；相互隔离的第一腔室和第二腔室，第一腔室和第二腔室设置在连接主体内，第一腔室具有与连接主体外部连通的进气口，第二腔室具有与连接主体外部连通的出气口，第一腔室通过第一连通口与第一通道连通，第二腔室通过第二连通口与第一通道连通，第二腔室通过第三连通口与第二通道连通，其中，第一连通口位于第二连通口的上方。
进一步地，连接主体包括：壳体；第一连接管，穿设在壳体内，第一通道设置在第一连接管内；隔板结构，设置在壳体内并连接在第一连接管的外壁上；第二连接管，连接在壳体的底部，第二通道设置在第二连接管内，其中，第一连接管、隔板结构以及壳体之间形成第一腔室和第二腔室。
进一步地，第一连接管的下端口封闭，第一连通口和第二连通口设置在第一连接管的侧壁上。
进一步地，隔板结构包括第一隔板，第一隔板与第一连接管连接，第一腔室通过第一隔板、壳体及第一连接管围成。
进一步地，隔板结构还包括第二隔板，第二隔板设置在第一连接管的下端口处并封堵下端口，第二腔室通过第一隔板、第二隔板、壳体及第一连接管围成。
进一步地，第一隔板包括第一水平板段及竖直板段，竖直板段连接在第一水平板段的沿其周向方向上的两端处。
进一步地，壳体的顶部具有开口，竖直板段向上延伸至开口处并将开口分隔形成进气口和出气口。
进一步地，第三连通口设置在第二隔板上，第三连通口与出气口位于竖直板段的同一侧。
进一步地，第二隔板包括第二水平板段及设置在第二水平板段上的倾斜板段，倾斜板段位于第一连接管的下端口内以实现导流，第二连通口设置在第一连接管的侧壁上。
进一步地，连接主体还包括用于遮挡在壳体上方的挡板结构，挡板结构与壳体的顶部的开口之间具有距离，挡板结构连接在第一连接管的外壁上。
进一步地，挡板结构包括第一档板，第一档板连接在第一连接管的外壁上并位于进气口的上方。
进一步地，挡板结构还包括第二档板，第二档板连接在第一连接管的外壁上并位于出气口的上方。
进一步地，第一连接管与隔板结构为一体结构，壳体和第二连接管为一体结构。
进一步地，隔板结构可拆卸地连接在壳体上。
进一步地，连接主体还包括用于连接隔板结构和壳体的固定结构，固定结构包括：固定凸出部，设置在壳体的内壁上，固定凸出部上具有沿壳体的周向延伸的卡槽；固定卡接部，设置在隔板结构上，固定卡接部与卡槽配合以固定隔板结构和壳体。
应用本发明的技术方案，在连接主体内设置第一通道、第二通道、第一腔室以及第二腔室。其中，第二通道位于第一通道的下方。第一腔室和第二腔室相互隔离。第一腔室的进气口、第二腔室的出气口均与连接主体外部连通。第一腔室通过第一连通口与第一通道连通。第二腔室通过第二连通口与第一通道连通。第一连通口位于第二连通口的上方。当通过上述管路连接装置对第一管路(例如空调内机的排水管)和第二管路(例如下水管道)进行连接时，第一管路与上连接口连接，第二管路与下连接口连接。当第一管路向第二管路排液时，液体依次通过上连接口、第一通道、第二连通口、第二腔室、第三连通口、第二通道、下连接口流向第二管路。当具有第一管路的设备内形成负压(例如空调器开启瞬间形成负压)时，第一管路会开始倒吸气体。此时，首先，第二管路内的大部分具有腐蚀性、臭味的气体依次通过下连接口、第二通道、第三连通口、第二腔室、出气口直接排入至连接主体外部大气；其次，由于第一连通口位于第二连通口的上方，第一管路会优先通过第一连通口、第一腔室、进气口倒吸连接主体外部的清洁的气体。因此，上述结构可以在不影响第一管路(空调内机的排水管)向第二管路(下水管道)排水的同时，防止气体倒灌现象的发生，即防止第二管路(下水管道)内的具有腐蚀性、臭味的气体通过第一管路(空调内机的排水管)倒吸入设备(空调器)中，从而防止对该设备造成损害。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
如图1所示，本实施例的管路连接装置用于连接空调内机的排水管与下水管道。上述管路连接装置包括连接主体、第一通道21、第二通道22、第一腔室31以及第二腔室32。其中，连接主体具有上连接口11和下连接口12。第一通道21和第二通道22设置在连接主体内。第二通道22位于第一通道21的下方。第一通道21的上端与上连接口11连通。第二通道22的下端与下连接口12连通。第一腔室31和第二腔室32设置在连接主体内并相互隔离。第一腔室31具有与连接主体外部连通的进气口311。第二腔室32具有与连接主体外部连通的出气口 321。第一腔室31通过第一连通口与第一通道21连通。第二腔室32通过第二连通口与第一通道21连通。第二腔室32通过第三连通口与第二通道22连通。第一连通口位于第二连通口的上方。
应用本实施例的管路连接装置，在连接主体内设置第一通道21、第二通道22、第一腔室31以及第二腔室32。其中，第二通道22位于第一通道21的下方。第一腔室31和第二腔室32相互隔离。第一腔室31的进气口311、第二腔室32的出气口321均与连接主体外部连通。第一腔室31通过第一连通口与第一通道21连通。第二腔室32通过第二连通口与第一通道21连通。第一连通口位于第二连通口的上方。当通过上述管路连接装置对空调内机的排水管和下水管道进行连接时，空调内机的排水管与上连接口11连接，下水管道与下连接口12连接。当排水管向下水管道排液时，冷凝水依次通过上连接口11、第一通道21、第二连通口、第二腔室32、第三连通口、第二通道22、下连接口12流向下水管道。当具有空调器开启瞬间形成负压时，排水管会开始倒吸气体。此时，首先，下水管道内的大部分具有腐蚀性、臭味的气体依次通过下连接口12、第二通道22、第三连通口、第二腔室32、出气口321直接排入至连接主体外部大气；其次，由于第一连通口位于第二连通口的上方，排水管会优先通过第一连通口、第一腔室31、进气口311倒吸连接主体外部的清洁的气体。因此，上述结构可以在不影响空调内机的排水管向下水管道排水的同时，防止气体倒灌现象的发生，即防止下水管道内的具有腐蚀性、臭味的气体通过空调内机的排水管倒吸入空调器中，从而防止对空调器造成损害、影响空调的使用寿命，并且可以防止气体进入空调房内危害人体的健康。
如图1至图5所示，在本实施例的管路连接装置中，连接主体包括壳体41、第一连接管42、隔板结构以及第二连接管43。其中，第一连接管42穿设在壳体41内，第一通道21设置在第一连接管42内。隔板结构设置在壳体41内并连接在第一连接管42的外壁上。第二连接管43连接在壳体41的底部。第二通道22设置在第二连接管43内。第一连接管42、隔板结构以及壳体41之间形成第一腔室31和第二腔室32。在本实施例中，隔板结构包括第一隔板441和第二隔板442。其中，第一隔板441与第一连接管42连接，第一腔室31通过第一隔板441、壳体41及第一连接管42围成。第二隔板442设置在第一连接管42的下端口处并封堵下端口，第二腔室32通过第一隔板441、第二隔板442、壳体41及第一连接管42围成。上述具体结构形成第一通道21、第二通道22、第一腔室31以及第二腔室32，从而实现管路连接装置的防倒灌的功能。
需要说明的是，连接主体的结构不限于此，在图中未示出的其他实施方式中，连接主体的隔板结构与第一连接管、第二连接管、壳体可以为其他设置关系。例如，只设置第一隔板，同时保证第一连接管的下端口封闭，第一连通口和第二连通口设置在第一连接管的侧壁上。
如图1至图5所示，在本实施例的管路连接装置中，第一隔板441包括第一水平板段4411及竖直板段4412。该竖直板段4412连接在第一水平板段4411的沿其周向方向上的两端处。上述两端处的两个竖直板段4412与第一水平板段4411、壳体41、第一连接管42共同围成第一腔室31。上述结构减小了第一腔室31的空间，增大了第二腔室32的空间。在本实施例中，壳体41的顶部具有开口。竖直板段4412向上延伸至开口处并将开口分隔形成进气口311和出 气口321。上述竖直板段4412可以实现进气口311和出气口321并列设置在壳体41的顶部。该竖直板段4412用于阻隔进气口311和出气口321，防止出气口321的臭味气体污染到进气口311的清洁气体。同时，通过上述结构形成进气口311和出气口321较为简单，易于加工制造。
如图1、图2以及图4所示，在本实施例的管路连接装置中，第三连通口设置在第二隔板442上。第三连通口与出气口321位于竖直板段4412的同一侧。上述第三连通口与出气口321的设置位置可以缩短气体从第三连通口流动到出气口321的距离，使下水管道内的气体更加容易地通过出气口321排出。
如图1至图5所示，在本实施例的管路连接装置中，第二隔板442包括第二水平板段4421及设置在第二水平板段4421上的倾斜板段4422。倾斜板段4422位于第一连接管42的下端口内以实现导流。第二连通口设置在第一连接管42的侧壁上。上述倾斜板段4422可以对第一连接管42中流下的液体起到导流的作用。此外，第三连通口与第二连通口位于竖直板段4412的不同侧，这样可以增长第三连通口与第二连通口之间的距离。当空调器内产生负压时，下水管道内的大部分具有腐蚀性、臭味的气体会通过出气口321直接排入至大气，但是也可能会有少部分具有腐蚀性、臭味的气体通过第二腔室32流动至第二连通口处。在上述情况发生时，首先由于第三连通口与第二连通口之间的距离较长，气体流动到第二连通口处时的速度明显减小；其次由于倾斜板段4422的倾斜设置，可以对气体起到一定的阻挡作用。上述原因导致少部分具有腐蚀性、臭味的气体会在第二腔室32靠近第二连通口的位置堆积，从而这部分气体不会顺着第一通道21倒吸入空调器内。
如图6至图10所示，在本实施例的管路连接装置中，连接主体还包括用于遮挡在壳体41上方的挡板结构。挡板结构与壳体41的顶部的开口之间具有距离。挡板结构连接在第一连接管42的外壁上。上述挡板结构可以防止外部的柳絮等杂物进入壳体41内。在本实施例中，挡板结构包括第一档板451和第二档板452。第一档板451连接在第一连接管42的外壁上并位于进气口311的上方。第二档板452连接在第一连接管42的外壁上并位于出气口321的上方。
如图6至图11所示，在本实施例的管路连接装置中，第一连接管42与隔板结构为一体结构，壳体41和第二连接管43为一体结构，这样可以通过两个连接结构安装在一起形成管路连接装置，更加便于制造。在本实施例中，隔板结构可拆卸地连接在壳体41上，这样使安装更加方便。
如图1至图5所示，在本实施例的管路连接装置中，连接主体还包括用于连接隔板结构和壳体41的固定结构46。固定结构46包括固定凸出部461和固定卡接部462。固定凸出部461设置在壳体41的内壁上，固定凸出部461上具有沿壳体41的周向延伸的卡槽。固定卡接部462设置在第二隔板442的第二水平板段4421上。固定卡接部462包括沿水平方向设置的卡接凸边，该卡接凸边转动一定角度后就可以卡进固定凸出部461的卡槽内，从而实现隔板结构和壳体41的固定。此外，固定卡接部462还包括设置在卡接凸边远离固定凸出部461的一侧的限位块，该限位块可以对卡接凸边进行限位，防止卡接凸边转动过度从卡槽中脱出。 当然，固定卡接部462的设置位置不限于此，在图中未示出的其他实施方式中，固定卡接部可以设置在第一隔板的第一水平板段上。
如图2至图5所示，当安装管路连接装置时，先将第一连接管42与隔板结构组成的结构插入至壳体41和第二连接管43组成的结构中(第一装配状态)，再旋转一定的角度，使固定凸出部461和固定卡接部462配合固定(第一装配状态)。然后将空调器排水管装配到上连接口11上，再将整个装置插入下水管道中，从而完成管路连接装置的安装。当空调器开机时，排水管吸入的主要是从第一腔室31的进气口311进来的大气中的清洁的气体。而由于管路连接装置内部的结构限制，下水管道中的具有腐蚀性、臭味的气体最终排向大气中或在装置中蓄积，不会被吸入空调器内部，从而使空调内的气体干净了许多，腐蚀性气体不被倒吸入空调器内，空调内的元器件也不会遭受致命损害。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
