Description

磁悬浮地漏芯子 技术领域
本发明属于地漏技术领域，涉及一种磁悬浮地漏芯子。
背景技术
地漏是连接排水管道系统与室内地面的重要接口，它被安装于厨房、卫生间和阳台等各个场所的地面。地漏的体积虽小，但是作为住宅中排水系统的重要部件，它的性能好坏直接影响室内空气的质量，对卫浴间的异味控制非常重要。
为此，人们设计了一种自动密封式地漏并申请了中国专利(其申请号为：200920314302.0；其公告号为：CN201554081U)，该自动密封式地漏包括具有进水口和出水口的筒体和位于筒体上方的面板，筒体进水口与面板相通，面板与筒体可拆卸连接，筒体的出水口处设有密封板，筒体的下方还设有能使密封板垂直于面板上下平动的导向机构，在密封板的下方设有利用磁性使密封板密封出水口的复位机构。该自动密封式地漏在不使用时，利用复位机构的磁性可对密封板产生向上的作用力而使其密封出水口；反之，当地漏的密封板上侧积有水量，则在水的重力作用下，可推动密封板下降并打开出水口实现出水。这样的结构可在地漏不下水时实现自动密封，避免臭气从地漏处溢出。
但是，在地漏的实际使用过程中，需要从地漏处排出的水往往参杂有部分细小的杂质，而上述自动密封式地漏中用于密封出水口的密封板呈平板状，极易使杂质残留在密封板的上侧，进而导致密封板和筒体之间产生粘连或者因杂质的存在而无法有效密封的情况，地漏的使用可靠性差。
发明内容
本发明的目的是针对现有技术存在的上述问题，提出了一种磁悬浮地漏芯子，所要解决的技术问题是如何提高地漏使用的可靠性。
本发明的目的可通过下列技术方案来实现：
一种磁悬浮地漏芯子,包括呈筒状的筒体、连接于筒体内的呈筒状的内壳以及密封件，所述的筒体的下端连接有支架，上述密封件包括呈杆状的杆部以及固定于杆部上端的密封部，所述的杆部穿设于上述支架内，所述的密封件与支架之间设置有能在密封件向下移动后使其向上复位的复位机构且密封件能在复位机构的作用下抵靠在上述内壳的下端并密封，其特征在于，所述的密封部的中部向上凸起并使密封部的上侧面形成包括曲面或数个倾斜平面的引流面，所述的密封部的引流面上还具有数个从上述密封部的中部向边沿延伸的导流槽，所述导流槽的侧壁具有倾斜或弯曲设置的导流面且该导流面能受到水流的作用力并使密封件绕杆部的轴线旋转。
本磁悬浮地漏芯子在不下水时，密封件受到磁性件一和磁性件二之间的磁力作用向上运动至密封部与内壳下端抵靠并实现密封。在下水时，筒体上端的水流从筒体和内壳内的空腔流向密封部，水流在自身重力作用下沿着密封部上侧面的引流面从密封部的凸起的中部沿着曲面或者倾斜平面流向密封部的边沿。在此流动过程中，水流流入引流面上的数个导流槽中并冲击在导流槽侧壁的导流面上，对导流面施加作用力并带动密封件绕着杆部的轴线旋转。在此旋转过程中，水中的杂质能沿着引流面向密封部的边沿移动且在密封件旋转的离心力作用下从密封部上侧面甩出，能有效避免杂质残留的情况，进而避免了密封部与内壳之间粘连或者留有间隙的情况发生，不仅使得密封件在水的重力作用下能稳定地开启，又避免了不下水时无法有效密封而导致臭气溢出的 情况，提高了本磁悬浮地漏芯子的可靠性。
在上述的磁悬浮地漏芯子中，所述的密封部的引流面上具有数个凸起呈条状的凸筋，相邻两个凸筋之间形成上述导流槽，所述的凸筋的侧面为上述导流面。导流槽由相邻的两个凸筋形成，使得导流槽的底面即为引流面，使得水流的流动更顺畅，保证水流具有足够的冲击力作用在导流面上从而带动密封件旋转，同时也使杂质能更顺畅地随着水流排除，不会残留，保证本磁悬浮地漏芯子的可靠性。
在上述的磁悬浮地漏芯子中，数个所述的凸筋围绕上述密封部的凸起分布，且各个凸筋均沿同一旋转方向弯曲成圆弧状，所述的凸筋上凹入一侧的侧面为上述导流面。凸筋围绕密封部中部的凸起分布，使得密封部的受力更均匀，而凸筋呈圆弧状可方便杂质随水流排出，避免杂质残留而造成粘连或无法有效密封的情况。
在上述的磁悬浮地漏芯子中，所述导流面与导流槽的底面之间所成角度为直角或锐角，所述的凸筋上凸出的一侧具有方便水流流入导向槽内的导向面。凸筋上导流面的一侧与导流槽的底面之间形成直角或锐角可使导流面能更好地承受水流的冲击，而凸筋上凸出的一侧设置导向面可减少水流的反向冲击，保证密封件在水流的冲击下能稳定地旋转。
作为另一种情况，在上述的磁悬浮地漏芯子中，所述的密封部的引流面上开设有数个凹入的导流槽，所述的导流槽围绕上述密封部的凸起分布且导流槽的侧壁与导流槽的底面垂直设置。根据需要，可采用在密封部上开设凹入的导流槽的方式来引导水路并承受水流的冲击力，水流在流入导流槽内时可将势能转换为动能，为密封件的旋转提供更大的驱动力。
在上述的磁悬浮地漏芯子中，所述的支架中部沿竖直方向开设有呈圆柱状的通孔，上述杆部呈圆杆状且穿设于上述通孔内， 所述的支架位于上述通孔处的侧壁具有数个凸出的能与上述杆部的外侧面相抵靠的抵靠部，数个抵靠部绕上述通孔的轴线分布。通过抵靠部的设置使得杆部穿设于通孔内并不与通孔的侧壁相接触，减少杆部与支架的接触面积，减少摩擦力，保证密封件能在水流的冲击下旋转。
在上述的磁悬浮地漏芯子中，所述的抵靠部呈长条状且沿着上述通孔的轴线方向设置，所述的抵靠部上朝向上述通孔轴线的侧面为向外凸出的圆弧面。抵靠部呈长条状可对杆部在整个轴线方向上提供有效地支撑，保持杆部竖直，避免密封件偏移；抵靠部上弧形面的设置，不仅进一步减少了与杆部的接触面积，且圆弧的形状也可减少杆部转动时的碰撞和阻碍，使得密封件的杆部旋转更顺畅。
在上述的磁悬浮地漏芯子中，所述的密封部的底面具有数个凸出的用于与上述支架相抵靠的支撑部，数个所述的支撑部围绕上述杆部设置。支撑部的设置使得密封部的底面不与支架直接抵靠，可避免因地漏中的出水量过大而造成密封部的底面与支架贴合的情况，不仅避免了摩擦力过大的情况，也能避免密封部在潮湿的环境下与支架粘连而无法复位的情况。
在上述的磁悬浮地漏芯子中，所述的密封部的边沿具有水平设置的呈环状的密封面，上述内壳的下端固定有呈环状的密封圈，所述的密封面能在上述密封件上移时与上述密封圈相抵靠。密封部上的水平密封面可使杂物在离心力的作用下更好地被甩出，避免残留的情况。
在上述的磁悬浮地漏芯子中，所述的内壳下端的外侧面具有凸出呈环状的安装环且该安装环与上述内壳同轴线设置，上述密封圈套设于所述内壳下端的外侧且密封圈的下端伸出上述内壳的下端面，所述的密封圈的内侧具有凹入的安装槽，所述的安装环卡入上述安装槽内，所述的安装环凸出内壳的高度小于上述安装 槽的深度，所述的安装环的宽度小于上述安装槽的宽度。密封圈与内壳上安装环这种较为松垮的安装方式，相对于紧密配合的安装方式来说，使得密封圈在受到外部作用力时具有变形的余量，能更好地与密封面完全贴合密封，保证密封效果。
在上述的磁悬浮地漏芯子中，所述的复位机构包括分别连接于支架和杆部内的磁性件一和磁性件二，所述的密封件能在磁性件一和磁性件二之间的磁力作用下上移并抵靠在所述的内壳下端。磁悬浮地漏在使用过程中，如出水量不大，密封件的密封部往往在磁力的作用下离开内壳的下端却仍与下侧的支架保持一段距离，即所谓的悬浮状态，此时密封件所受到的各种阻力最小，而本磁悬浮地漏芯子通过在密封件的密封部上设置引流面和导流槽的结构，利用水流的冲击力带动悬浮状态的密封件旋转，减少了阻力，使水流中的杂质在离心力的作用下能被完全甩离密封部。
作为另一种情况，在上述的磁悬浮地漏芯子中，所述的复位机构包括套设于上述杆部外侧的弹簧，所述的弹簧的一端与上述密封部的底面相抵靠，另一端与支架相抵靠。在水流量相对较大的情况下，也可采用弹簧来实现密封件的复位，并不会妨碍密封件的旋转。
与现有技术相比，本磁悬浮地漏芯子具有以下优点：
1、磁悬浮地漏在使用过程中，如出水量不大，密封件的密封部往往在磁力的作用下离开内壳的下端却仍与下侧的支架保持一段距离，即所谓的悬浮状态，此时密封件所受到的各种阻力最小，而本磁悬浮地漏芯子通过在密封件的密封部上设置引流面和导流槽的结构，利用水流的冲击力带动悬浮状态的密封件旋转，使水流中的杂质在离心力的作用下被甩离密封部，避免了杂质残留的情况，即本磁悬浮地漏芯子通过将磁悬浮结构、引流面和导流槽的结构相结合的方式来保证密封件的旋转，避免了密封部与内壳之间粘连或者留有间隙的情况发生，不仅使得密封件在水的重力 作用下能稳定地开启，又避免了不下水时无法有效密封而导致臭气溢出的情况，提高了本磁悬浮地漏芯子的可靠性。
2、本磁悬浮地漏芯子在支架上设置抵靠部配合密封部底面设置的支撑部结构来减少密封件与支架之间的接触面，进一步减少对密封件摩擦阻力，保证了密封件在水流的作用下能稳定有效地转动。
3、在内壳的下端较为宽松地设置密封圈再配合密封部上侧水平的密封面，能提高两者之间的密封效果。

具体实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
如图1和图2所示，本磁悬浮地漏芯子包括呈圆筒状的筒体1、同轴线地螺纹连接于筒体1内的呈圆筒状的内壳2以及密封件3，筒体1的下端通过两个支脚固连有大致呈椭圆球状的支架4。 密封件3包括呈圆杆状的杆部31以及固定于杆部31上端的密封部32，杆部31穿设于支架4内，支架4和杆部31内分别固连有磁性件一5和磁性件二7，且密封件3能在磁性件一5和磁性件二7的磁力作用下向上运动并抵靠在连接于内壳2的下端的圆环形密封圈6上实现密封。在本实施例中，支架4的具体结构、磁性件一5和磁性件二7的具体固定结构可参照申请人已申请的申请号为201520439877.0.的实用新型专利，这里对其具体结构不再赘述。
如图3所示，密封部32的中部向上凸起并使密封部32的上侧面形成为一半球面的引流面32a，该引流面32a上还具有数个凸起的且从密封部32的中部向边沿延伸的呈条状的凸筋32c，相邻两个凸筋32c之间形成导流槽32b。在本实施例中，密封部32为圆板状，其中部向上凸出呈半球状，密封部32的边沿水平延伸出呈圆环形的密封板，密封板上侧面为与内壳2的密封圈6相贴靠的密封圈6；数个凸筋32c围绕密封部32上凸起的最高点均匀分布于引流面32a上，且各个凸筋32c均沿同一旋转方向弯曲成圆弧状，凸筋32c上凹入一侧的侧面为导流面32c1，该导流面32c1与导流槽32b的底面之间所成角度为直角或锐角，这里，因导流面32c1和导流槽32b的底面均可为圆弧面，则呈圆弧面的的导流面32c1和导流槽32b的切面所成角度为直角或锐角，凸筋32c的顶面和凸出一侧的侧面形成一方便水流流入导向槽内的呈圆弧形的导向面32c2。
如图4所示，密封部32的底面还具有四个凸出呈条状的用于与支架4上端面相抵靠的支撑部32d，四个支撑部32d围绕密封件3的杆部31设置，且支撑部32d上用于与支架4相接触的面可为圆弧面。
如图5所示，支架4中部沿竖直方向开设有呈圆柱状的通孔41，杆部31穿设于通孔41内，支架4位于通孔41处的侧壁具有 数个凸出的能与杆部31的外侧面相抵靠的抵靠部42，数个抵靠部42绕通孔41的轴线均匀分布。在本实施例中，抵靠部42呈长条状且沿着通孔41的轴线方向设置，抵靠部42上朝向通孔41轴线的侧面为向外凸出的圆弧面。
如图6所示，内壳2下端的外侧面具有凸出呈环状的安装环21且该安装环21与内壳2同轴线设置，密封圈6套设于内壳2下端的外侧且密封圈6的下端伸出内壳2的下端面，用于与密封面32e相贴靠。密封圈6的内侧具有凹入的呈环形的安装槽61，安装环21卡入安装槽61内。安装环21凸出内壳2的高度小于安装槽61的深度，且安装环21的宽度小于安装槽61的宽度。
本磁悬浮地漏芯子在不下水时，密封件3受到磁性件一5和磁性件二7之间的磁力作用向上运动至密封件3上的密封面32e与内壳2下端的密封圈6贴靠。此时，密封圈6受到密封板的作用力发生小幅度变形而使密封圈6与密封板上的密封面32e完全贴靠以实现密封。在下水时，筒体1上端的水流从筒体1和内壳2内的空腔流向密封部32，水流在自身重力作用下沿着密封部32上侧的引流面32a从密封部32的凸起的中部最高点沿着曲面流向密封部32的边沿。
在此流动过程中，水流流入引流面32a上的相邻两个凸筋32c之间的导流槽32b中并冲击在凸筋32c的导流面32c1上，对导流面32c1施加作用力并带动密封件3绕着杆部31的轴线旋转。在此旋转过程中，水中的杂质能沿着引流面32a向密封部32的边沿移动且在密封件3旋转的离心力作用下沿着水平设置的密封板水平甩出，有效避免杂质残留的情况，进而避免了密封部32与内壳2之间因杂质存在而导致粘连或者留有间隙的情况发生，不仅使得密封件3在水的重力作用下能稳定地开启，又避免了不下水时无法有效密封而导致臭气溢出的情况，提高了本磁悬浮地漏芯子的可靠性。
而在密封件3的转动过程中，通过支撑部32d和抵靠部42的结构，使得密封件3与支架4的接触面大大减小，减少了密封件3旋转时受到的摩擦力，保证密封件3在水流的冲击下能稳定地旋转。
除以上技术方案以外，密封部32的上侧面还可呈棱锥状，即密封部32的中心点最高，中心点与边沿之间通过数个倾斜平面过度，导流槽32b可为直接开设于引流面32a上的凹入的为直槽的导流槽32b，而导流槽32b围绕密封部32的凸起分布且导流槽32b的侧壁与导流槽32b的底面垂直设置，该导流槽32b的延伸方向与棱锥侧面上从顶点至底面的最短线段的延伸方向不同，而是倾斜地设置于棱锥的侧面上；密封件3与支架4之间的复位机构还可采用弹簧，将弹簧套设于杆部31的外侧，并使其一端与密封部32的底面相抵靠，另一端与支架4相抵靠既可实现复位。当然，上述导流槽32b的形成方式、导流槽32b的设置方向、导流面32c1的形状、复位机构的选择以及引流面32a的形状可根据实际需要任意组合。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
