下面结合附图并参考具体实施例描述本公开。
在本公开的一个方面,提供一种隔膜泵,通过利用本公开内容的一个或多个实施方式解决了隔膜泵的隔膜寿命无法得到保证的技术问题。
图1示出了依据本公开一些实施例的隔膜泵的俯视图;图2示出了沿图1的A-A向截取的隔膜泵的剖视图;图3示出了图1中隔膜泵的爆炸图;图4示出了图1中隔膜泵的隔膜的结构示意图;图5示出了图4中隔膜的俯视图;图6示出了图4中隔膜的仰视图。结合图1、图2、图3、图4、图5和图6,本实施例的隔膜泵包括:摆动组件100、隔膜支架30和隔膜瓣40。隔膜瓣40 设置于隔膜支架30上,且与摆动组件100连接,在摆轮20静止时,隔膜瓣40的位置点位于初始位置。其中,位置点随着摆动组件100的摆动达到第一极限位置和第二极限位置,初始位置位于第一极限位置和第二极限位置的中部。
在一些实施例中,隔膜瓣40设置于隔膜支架30上,且与摆动组件100连接,通过隔膜支架30轴承隔膜瓣40。位置点随着摆动组件100的摆动达到第一极限位置和第二极限位置,其中,第一极限位置为摆动组件100推动位置点达到的最远位置,第一极限位置为摆动组件100拉动位置点达到的最远位置。由于在摆动组件100静止时,隔膜瓣40的位置点位于初始位置,初始位置位于第一极限位置和第二极限位置的中部,所以,当摆动组件100带动位置点进行动作时,位置点在工作中的变形应变为最小,减少隔膜瓣40的损耗,延长隔膜瓣40在工作过程中的寿命。
在一些实施例中,第一极限位置和第二极限位置之间设有中点,中点位于第一极限位置和第二极限位置的中间位置,初始位置与中点之间的距离占第一极限位置至第二极限位置之间的距离的30-70%,那么,当摆动组件100带动位置点进行动作时,位置点在工作中的变形应变小,减少隔膜瓣40的损耗,延长隔膜瓣40在工作过程中的寿命。
在一些实施例中,初始位置位于中点,当摆动组件100带动位置点进行动作时,那么,位置点在工作中的变形应变为最小,减少隔膜瓣40的损耗,延长隔膜瓣40在工作过程中的寿命。
结合图2,在一些实施例中,隔膜泵为竖向放置,因此,第一极限位置为摆动组件100推动位置点达到Z向最高位置,第二极限位置为摆动组件100拉动位置点达到的Z向最低位置。
结合图4、图5和图6,在一些实施例中,为了保证隔膜瓣40的使用寿命,位置点的数目为多个,位置点可位于隔膜瓣40的任意位置,多个位置点均位于第一极限位置和第二极限位置的中点,保证各个位置点在工作中的变形应变最小,使隔膜瓣40在工作中的变形应变最小,从而保证了隔膜瓣40在工作过程中的寿命最大。
结合图3,在一些实施例中,由于隔膜瓣40的数目为多个,所以,摆轮20的数目也为多个,多个摆轮20与多个隔膜瓣40一一对应,隔膜瓣40与相对应的摆轮20连接,通过摆轮20带动相对应的隔膜瓣40连接。
结合图2和图3,在一些实施例中,摆动组件100包括:运动支架10和摆轮20。摆轮20设于运动支架10上的摆轮20,通过运动支架10支撑摆轮20,并带动摆轮2动作。摆轮20与隔膜瓣40连接,以支撑隔膜瓣40,并带动隔膜瓣40动作。
结合图3,在一些实施例中,为了便于隔膜瓣40与摆轮20连接,隔膜泵还包括:压装组件50。压装组件50与摆轮20连接,以将隔膜瓣40压装到 摆轮20上,保证隔膜瓣40与摆轮20连接牢靠,便于摆轮20带动隔膜瓣40动作。
结合图3,在一些实施例中,压装组件50包括:压头501和连接件502。压头501与隔膜瓣40相抵触,隔膜瓣40设于摆轮20和压头501之间,通过压头501将隔膜瓣40压迫在摆轮20上,保证隔膜瓣40与摆轮20连接牢靠。连接件502穿设于压头501和隔膜瓣40与摆轮20连接,以使压头501、隔膜瓣40和摆轮20连接为一体结构。具体地,压头501上开设有第一通孔,隔膜瓣40上开设有第二通孔,摆轮20上开设有安装孔,第二通孔分别与第一通孔和安装孔连通,连接件502依次穿设于第一通孔和第二通孔与安装孔连接,以使压头501、隔膜瓣40和摆轮20连接为一体结构。
在一些实施例中,隔膜支架30上开设有通槽,摆轮20穿设于通槽与隔膜瓣40连接,便于摆轮20与隔膜瓣40连接,便于装配,同时,不干涉摆轮20的动作。
在一些实施例中,连接件502可以为螺栓,安装孔可以为螺栓孔,螺栓依次穿设于第一通孔和第二通孔与螺栓孔连接,便于将压头501和隔膜瓣40装配到摆轮20上,提高装配效率。
在一些实施例中,由于压头501将隔膜瓣40压迫在摆轮20上,也就是说,摆轮20主要带动与压头501相抵触的隔膜瓣40动作,隔膜瓣40与压头501相抵触的部位在工作过程中的形变大,所以,位置点与压头501相抵触,而由于位置点在工作中的变形应变最小,因此,使隔膜瓣40在工作中的变形应变最小,从而保证了隔膜瓣40在工作过程中的寿命最大。
在一些实施例中,由于压头501将隔膜瓣40压迫在摆轮20上,也就是说,摆轮20主要带动与压头501相抵触的隔膜瓣40动作,隔膜瓣40与压头501的边沿相抵触的部位在工作过程中的形变最大,所以,位置点与压头501的边沿相抵触,而由于位置点在工作中的变形应变最小,因此,使隔膜瓣40在工作中的变形应变最小,从而保证了隔膜瓣40在工作过程中的寿命最大。
结合图3,在一些实施例中,为了保证支撑隔膜瓣40的稳定性,隔膜泵还包括支撑件60。支撑件60设于隔膜支架30的内周面内,以与隔膜支架30的内壁形成嵌入槽,隔膜瓣40的边沿嵌设于嵌入槽内,也就是说,隔膜瓣40的底部边沿设置在支撑架60上,并与支撑架60连接,通过支撑架60支撑隔膜瓣40,并对隔膜瓣40的边沿进行紧固,保证摆轮20可以带动隔膜瓣40进行弹性形变。其中,嵌入槽的形状为L形。
结合图5和图6,在一些实施例中,隔膜瓣40大致呈圆角三角形,支撑件60也呈圆角三角形。可以理解,在其他实施方式中,隔膜瓣40与支撑件60还可以是其他的形状,只要隔膜瓣40与支撑件60的形状相一致,支撑架60可支撑隔膜瓣40即可。
结合图3,在一些实施例中,支撑架60的截面形状为环状,以支撑和紧 固隔膜瓣40,摆轮60穿设于支撑架60与隔膜瓣40连接,不会影响摆轮20带动隔膜瓣40弹性形变,也不会影响隔膜泵其他设备的布置和安装。
结合图2和图3,在一些实施例中,隔膜泵还包括盖板80。盖板80与隔膜支架30连接,通过隔膜支架20支撑盖板80。盖板80设有腔室,隔膜瓣40设于腔室内,摆轮20带动隔膜瓣40在腔室内进行往复的收缩和膨胀。
结合图2和图3,在一些实施例中,盖板80和隔膜支架30其中一个开设有卡槽,另一个设有卡扣301,卡扣301卡设于卡槽内,便于盖板80与隔膜支架30的连接,提高装配效率,通过卡扣301卡设于卡槽,也可以起到定位的作用,进一步地提高了装配效率。
结合图3,在一些实施例中,盖板80开设有卡槽,和隔膜支架30设有卡扣301,卡扣301卡设于卡槽内,便于盖板80与隔膜支架30的连接,提高装配效率,通过卡扣301卡设于卡槽,也可以起到定位的作用,进一步地提高了装配效率。
结合图2和图3,在一些实施例中,盖板80与隔膜支架30之间设有密封件805,能够紧密密封盖板80与隔膜支架30,避免水流在盖板80与隔膜支架30之间传输时泄漏。本实施方式中,密封件805为弹性密封圈。可以理解,密封件805还可以为密封填料等其他类型的密封件。
结合图2和图3,在一些实施例中,盖板80与隔膜瓣40之间设置有进水压片801,也就是说,进水压片801设于腔室内,且与隔膜瓣40形成密封腔。盖板80远离隔膜瓣40的一端上还设置有出水压片802,隔膜瓣40、进水压片801及出水压片802相互配合,利用摆轮20沿其轴向方向的往复直线运动,驱动水流往复吸入并稳压排出。进水压片801及出水压片802均由弹性材料制成,其可弹性地扩展或伸缩。
结合图2和图3,,在一些实施例中,盖板80上设有第一凹槽803,进水压片801设于第一凹槽803内,且第一凹槽803上开设有多个进水口8031,出水压片801控制出进水口8031的通断。盖板80上设有第二凹槽804,出水压片802设于第二凹槽804内,且第二凹槽804上开设有多个出水口8041,进水压片802控制出水口8041的通断。其中,第一凹槽803的下凹方向与第二凹槽804的下凹方向相反。
在一些实施例中,当隔膜瓣40与盖板80之间形成的密封腔扩张时,密封腔内的压力减小形成相对低压,盖板80与外界之间的空间形成相对高压,相对低压的密封腔具有吸力,进水压片801与进水口8041之间形成间隙,外界的水流通过进水口8041吸入该密封腔内,相对高压的盖板80与外界之间的空间具有推力,该推力使出水压片802紧密的贴合在出水口8041上,从而堵住出水口8041,此时出水口8041封闭,进水口8041将水流吸入密封腔内,从而完成吸水过程。当隔膜瓣40与盖板80之间形成的密封腔收缩时,密封腔内的压力增大形成相对高压,盖板80与外界之间的空间形成相对低压,相 对高压的密封腔具有推力,使进水压片801紧密的贴合在进水口8041上,从而堵住进水口8041,相对低压的盖板80与外界之间的空间具有吸力,出水压片802与出水口8041之间形成间隙,其通过出水口8041将密封腔内的水流吸入盖板80与外界之间,实现水流从密封腔内流出,此时进水口8041关闭,出水口8041将水流排出密封腔,从而完成排水过程。
在一些实施例中,为了描述的方便。仅叙述了一个密封腔的作用过程。可以理解,在其他实施方式中,隔膜泵也可以包括多个的密封腔,只要摆轮20、压头501、隔膜瓣40、第一凹槽803、进水压片801具有对应相同的数量即可,密封腔数量越多,提供的水流的压力就相对越稳定,多个密封腔组合使用,能够加强水流的压力,均匀水压的变化,从而可以提供水压稳定的加压水流。
结合图2和图3,在一些实施例中,为了为摆轮20的动作提供动力,隔膜泵还包括驱动组件70。驱动组件70与运动支架10连接,通过驱动组件70带动运动支架10动作,运动支架10带动摆轮20动作,摆轮20带动隔膜瓣40动作。
结合图2和图3,在一些实施例中,驱动组件70包括:电机传动杆701、斜盘702和轴承703。斜盘702套设于电机传动杆701上,通过电机传动杆701带动斜坡702动作。轴承703套设于斜盘702上,运动支架10套设于轴承703上,轴承703用于将动力传递给轴承703,再由轴承703传递给运动支架10,进而,运动支架10带动摆轮20动作,摆轮20带动隔膜瓣40到达第一极限位置或第二极限位置。
结合图2和图3,在一些实施例中,驱动组件70还包括底座704,底座704与隔膜支架30通过多个紧固件90连接,通过底座704支撑隔膜支架30,保证隔膜支架30的稳定性。其中,紧固件90可以为螺栓、螺钉或螺杆。
在一些实施例中,驱动组件70还包括驱动电机705,驱动电机705的动作端与电机传动杆701,用于带动电机传动杆701动作。
结合图4、图5和图6,在一些实施例中,多个隔膜瓣40形成隔膜,隔膜的边沿处设有凸起401,也就是说,隔膜的边沿处上沿其轴线方向延伸并形成凸起401,凸起401能够加强隔膜的结构强度,降低隔膜在驱动组件70往复作用下的疲劳损害。
在一些实施例中,隔膜的边沿处设有凸起401,而位置点不设于凸起401上,也就是说,位置点与凸起401互不干涉。在其它实施方式中,隔膜的边沿处没有设有凸起401,那么多个位置点形成隔膜瓣40,多个隔膜瓣40形成隔膜。
结合图2和图3,在一些实施例中,驱动电机705带动电机传动杆701动作,电机传动杆701带动斜盘702随同转动,斜盘702与轴承703相临近的一端均为斜面,斜盘702与轴承703以斜面接触的方式相互抵靠,斜盘702 在电机传动杆701的驱动下转动并带动轴承703沿斜盘702的中心轴线方向往复运动,轴承703与隔膜支撑架30固定连接,轴承703的往复直线运动带动隔膜支撑架30及压头502也做往复直线运动,压头502抵持隔膜瓣40,从而实现将电机传动杆701的回转运动转换为作用于隔膜组件20的变形。
在本公开的另一方面,提供了一种净水器,该净水器采用了所述隔膜泵,该隔膜泵的具体结构参照上述实施例,由于隔膜泵采用了上述所有实施例的全部技术方案,因此至少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。
在一些实施例中,当该净水器采用了所述隔膜泵时,隔膜泵的隔膜瓣40设置于隔膜支架30上,且与摆动组件100连接,通过隔膜支架30轴承隔膜瓣40。位置点随着摆动组件100的摆动达到第一极限位置和第二极限位置,其中,第一极限位置为摆动组件100推动位置点达到的最远位置,第一极限位置为摆动组件100拉动位置点达到的最远位置。由于在摆动组件100静止时,隔膜瓣40的位置点位于初始位置,初始位置位于第一极限位置和第二极限位置的中部,所以,当摆动组件100带动位置点进行动作时,位置点在工作中的变形应变为最小,减少隔膜瓣40的损耗,延长隔膜瓣40在工作过程中的寿命,继而延长隔膜泵的使用寿命,也延长了净水器的使用寿命。
