Description

一种导液插接结构、添加剂投放模块及衣物处理设备 技术领域
本发明属于衣物添加剂投放技术领域，具体地说，涉及一种导液插接结构、添加剂投放模块及衣物处理设备。
背景技术
随着自动化技术的发展，衣物处理设备等家电变得越来越智能，现有的洗衣机通常配置有衣物添加剂投放模块，现有的添加剂投放模块通常设有多个储液盒装有洗涤剂、柔顺剂和消毒剂等多种添加剂，以实现对不同材质的衣物进行更合适的处理。其中，添加剂投放模块对于储液盒中的洗涤剂的检测通常是在储液盒上增加各种标识，通过标识来识别所添加的添加剂种类。
申请号为201810179883.5的发明专利公开了一种洗涤添加剂自动投放装置，包括盛放洗涤添加剂的容器和承载该容器的安装部，所述容器可取放的设置在安装部内，该装置还包括检测容器内部液位的至少一组液位检测结构。所述液位检测结构包括探测部，所述探测部为导电探针，与电路连接的导电部，所述探测部一端密封插入容器内，另一端在容器放置在安装部内时与导电部接触导通电路，在容器从安装部取出时与导电部分开断开电路。
上述申请公开的洗涤添加剂自动投放装置，通过在盛放洗涤添加剂的容器内设置的导电探针来实现对容器内的添加剂的余量进行检测，但是盛放洗涤添加剂的容器(储液盒)的制作难度大，成本高，而现有技术中又鲜有设置在非储液盒上的检测或识别方法，所以现在需要一种不直接设置在储液盒上的检测或识别技术，进而降低储液盒的制作成本和制作难度。
有鉴于此特提出本发明。

下面结合实施例对本发明进行进一步地详细的说明。
实施例一
如图1至图8所示，本发明提供了一种导液插接结构，设于添加剂投放模块上，可由储液盒1的投放口插入到储液盒1内与其内部的添加剂连通，其中导液插接结构上设置有用于检测储液盒1内添加剂的类别和/或余量的检测装置。
如图1至图5所示，本实施例提供了一种导液插接结构，在导液插接结构上设有与储液盒1内的添加剂相接触导通的两个导电探针24，基于两个导电探针24通电后的电导率信息推断出储液盒1内添加剂的类别和/或余量。
具体地，导液插接结构包括可由储液盒1的投放口插入到储液盒1内的导液插接管2，导电探针24固定设置在所述导液插接管2上，所述导电探针24固定设置在导液插接管2上。导电探针24一端为用于探测类别和/或余量的探测端241，另一端为与外部检测电路连接的接线端242，所述导电探针24的探测端241伸入到所述导液插接管2内和/或储液盒1内。优选地，所述导电探针24嵌入或者贴合固定在所述导液插接管2的内壁上。
其中，两根导电探针24为间隔一定距离设置，当探测端241与添加剂接触时，两根通电的导电探针24与添加剂形成闭合的电路，由于不同种类的添加剂电导率不同，通过对电导率的检测，推断出储液盒1内添加剂的类别。
当储液盒1内添加剂余量不足时，两根导电探针24至少有一根不能与添加剂相接触，即不能构成稳定闭合的电路，此时的电导率为零，即可推断出储液盒1内的添加剂余量不足。
进一步地，导液插接管2包括导液管段21和连接在导液管段21端部外径缩小的插接管段22，插接管段22侧壁开设有导液口28，添加剂通过导液口28流入到导液插接管2中。

在本实施例的另一种优选方案中，所述导电探针24的接线端242直接构成导电触片，与外部检测电路相连接，结构一体化更强，布局更加合理。所述导液插接管2的管壁上设有供所述导电探针24的接线端242穿出的第二通孔，所述导电探针24的接线端242由所述第二通孔伸出与外部检测电路连接；优选地，所述导液插接结构还包括连接导液插接管2外周壁上的保护罩筒26，所述保护罩筒26罩设在所述导电探针24外，所述导电探针24下端的接线端242伸出所述保护罩筒26与外部检测电路连接；更优地，所述第一通孔和第二通孔在导液插接管2的管壁上连通，所述导电探针24的探测端241伸出第一通孔，接线端242伸出第二通孔。第一通孔和第二通孔的设置，使导电探针24的在导液插接管2上的安装更加简单方便，有效的提升所述导液插接结构的生产效率。更进一步地，所述第一通孔和第二通孔与所述导电探针24的周壁之间设置有密封圈。通过以上设置，通过导电探针24直接对接触的添加剂进行检测，即可得出储液盒1内添加剂的种类和/或余量的信息，无需在储液盒1等装置上做特殊的标示，降低了储液盒1等耗材的制作难度和制作成本。
实施例二
本实施例提供了一种设置有流量检测机构的导液插接结构，根据流量检测机构获取到的流量信息，推断出储液盒1内的添加剂的类别和/或余量；优选地，所述导液插接结构包括可由储液盒1的投放口插入到储液盒1内的导液插接管2，所述导液插接管2内具导流通道27，所述流量检测机构包括设置在导流通道27内的流量传感器；优选地，所述导液插接管2包括导液管段21和连接在导液管段21端部外径缩小的插接管段22；所述流量检测机构包括设置在插接管段22外周壁、或导液管段21与插接管段22之间的环形连接壁25上的流量传感器。
具体地，以检测添加剂类别为例，在保持外界条件不变的情况下，通过多次添加不同种类的添加剂以得到各种添加剂所对应的流量传感器转速范围得到类别匹配表。市场上的添加剂一般包括洗涤剂、柔顺剂、消毒剂，其中洗涤剂粘稠度最大、柔顺剂的粘稠度次之、消毒剂的粘稠度最小，在外界条件相同的情况下，当添加剂为洗涤剂时，流量传感器检测到的转速最小，当添加剂为消毒剂时，流量传感器检测到的转速最大。
例如，类别匹配表中洗涤剂对应的转速范围在N1-N2、柔顺剂对应的流量计转速范围在N3-N4、消毒剂对应的流量计的转速范围在N5-N6，其中N1＜N2≤N3＜N4≤N5＜N6。在外界条件不变的情况下，通过判断流量传感器检测到的转速所处的范围，则可推断出该添加剂为洗涤剂/柔顺剂/消毒剂。
当流量传感器检测添加剂余量时，在外界条件相同的情况下，空气或者水等粘度较小的 流体的流速较快，相应的流量传感器检测到的转速较大；粘度较高的添加剂流过时，相应的流量传感器检测到的转速较小。
由于添加剂在流经流量传感器时相比空气流速要慢，通过对比流量传感器的转速即可判断添加剂是否添加完毕，当流量传感器检测到的转速较大时，则可推断添加剂余量较少。具体地，通过多次在不同余量的情况下添加添加剂，可得到不同剩余量时流量传感器所对应的转速范围的余量匹配表。在添加剂流经流量传感器时，流量传感器实时检测或者每间隔一定时间检测一次转速，所检测的转速大于余量匹配表中最低余量所对应的转速时，则推断出添加剂的余量不足。

具体地，外套筒151和阀壳111轴向的一端分别为敞口端，另一端分别为封闭端，阀壳111的封闭端经外套筒151的敞口端插入外套筒151内，第二压缩弹簧504504设于阀壳111的封闭端和外套筒151的封闭端之间。
外套筒151和阀壳111轴向的两端中的一端为敞口端，另一端为封闭端，阀壳111轴封闭的一端在外套筒151的敞口端插入外套筒151内，第二压缩弹簧504504位于外套筒151内，第二压缩弹簧504504设于阀壳111封闭端的外部和外套筒151封闭端的内部，第二压缩弹簧504504为阀壳111在外套筒151内做伸缩动作提供恢复力。
如图17所示，本发明的实施例中，阀壳111的封闭端轴向凸伸形成环形凸起114，环形凸起114的内周壁与阀壳111封闭端之间形成开口朝向外套筒151封闭端的导向槽115，第二压缩弹簧504504的一端设于导向槽115内。
本发明的实施例中，阀壳111的封闭端外部设环形凸起114，环形凸起114与阀壳111同轴设置，环形凸起114的内周壁与阀壳111的封闭端围成导向槽115，导向槽115的槽口朝向外套筒151的封闭端，第二压缩弹簧504轴向的一端设于导向槽115内，具体地，第二压缩弹簧504的一端设于阀壳111封闭端上；导向槽115对第二压缩弹簧504的伸缩起到导向的作用，使得第二压缩弹簧504在一定的限制范围内伸缩，防止第二压缩弹簧504伸缩错位，导致不能为阀壳111提供恢复力。
环形凸起114为圆环形，第二压缩弹簧504部分嵌入环形凸起114为与阀壳111的封闭端围成的导向槽115内，第二压缩弹簧504的径向尺寸小于环形凸起114的径向尺寸，但是第二压缩弹簧504的径向尺寸略小于环形凸起114的径向尺寸，以使得导向槽115能够对第 二压缩弹簧504准确地导向。
如图16和图17所示，本发明的实施例中，外套筒151的封闭端轴向凸伸形成一端敞口、另一端封闭的导向管152，导向管152的径向尺寸小于外套筒151的径向尺寸，导向管152经导向管152的敞口端与外套筒151连通。
本发明的实施例中，外套筒151封闭端的外部设导向管152，导向管152由外套筒151的封闭端向外凸伸形成，具体地，外套筒151封闭端向外套筒151外轴向凸伸形成条形凸块，条形凸块内部中空形成导向管152，导向管152轴向的一端为封闭端，另一端为敞口端，导向管152的敞口端与外套筒151连通，导向管152的封闭端作为外套筒151的封闭端；导向管152对第二压缩弹簧504的伸缩起到导向的作用，使得第二压缩弹簧504在一定的限制范围内伸缩，防止第二压缩弹簧504伸缩错位，导致不能为阀壳111提供恢复力。
导向管152的径向尺寸小于外套筒151的径向尺寸，且导向管152的径向尺寸大于第二压缩弹簧504的径向尺寸，但是第二压缩弹簧504的径向尺寸略小于导向管152的径向尺寸，以使得导向管152能够对第二压缩弹簧504准确地导向。
具体地，第二压缩弹簧504轴向的另一端经导向管152的敞口端插入导向管152内，第二导向管152与外套筒151同轴设置，使得导向管152能够进一步地对第二压缩弹簧504进行准确地导向。
如图17所示，本发明的实施例中，还包括凹槽状的盒盖16，盒盖16槽底的中部轴向凸伸形成两端敞口的内套筒17，阀壳111经内套筒17一端的敞口插入内套筒17，导液管12经内壳另一端的敞口插入阀壳111内，内套筒17的一端经外套筒151的敞口端插入外套筒151内。
本发明的实施例中，盒盖16扣合在储液盒1的投放口31处，用于封盖或敞开储液盒1的投放口31，具体地，储液盒1投放口31设一圈向盒外凸伸的凸起；盒盖16呈凹槽状，盒盖16槽底的中部轴向凸伸形成两端敞口的内套筒17，内套筒17的外周壁与盒盖16的槽壁之间具有间隙，上述凸起插入间隙内；
盒盖16槽底的中部设与内套筒17敞口端连通的通孔，导液管12经通孔、内套筒17敞口端、阀壳111的敞口端插入阀壳111内，内套筒17的一端经外套套筒的敞口端插入外套筒151内，内套筒17对外套筒151起到稳固的作用，减少阀芯113、阀壳111在伸缩移动时的晃动。其中，内套筒17也为圆筒状，内套筒17与外套筒151同轴设置。
内套筒17插入外套筒151的一端与外套筒151的内壁之间相抵，具体地，外套筒151沿外套筒151的敞口端到封闭端的方向分为第一段153和第二段154，第二段154的内壁相对第一段153的内壁向内凸伸形成台阶155，内套筒17的一端与外套筒151内壁上的台阶155相抵，提高外套筒151和内套筒17之间的一体性和同步性；为了进一步提高外套筒151和内套筒17之间的一体性和同步性，第二段154的内周壁相对第一段153的内周壁向内凸伸形成一圈台阶155，增大内套筒17的一端与外套筒151内壁的抵接面积；具体地，内套筒17在轴向方向上的最外层的截面与台阶155相抵。
此外，内套筒17的内周壁径向凸伸形成第一滑动凸起，阀壳111的外周壁径向凸伸形成第二滑动凸起，第一滑动凸起和第二滑动凸起沿轴向延伸，均为长条形，第一滑动凸起和第二滑动凸起沿周向并排相抵，第一滑动凸起与阀壳111外周壁相抵，第二滑动凸起与内套筒17的内周壁相抵。
如图19所示，本发明的实施例中，阀壳111的下部设导液口116，外套筒151的下部设裸露导液口116的开口156，开口156从外套筒151的敞口端延伸至外套筒151的封闭端。
本发明的实施例中，阀壳111的下部径向凸伸形成导管，导管的内壁围成导液口116，在投放洗涤剂时，洗涤剂从导液口116进入导液流道112内，再从导液流道112内进入导液管12内；
外套筒151的下部设有开口156，开口156将导液口116裸露在外，使得洗涤剂能够从导液口116进入至导液流道112内，为了进一步降低外套筒151的制作成本，开口为外套筒 151下部的敞口，开口从外套筒151的敞口端延伸至封闭端。
对于储液盒1的密封来说，导液管12插入阀壳111的一端上套设有环形密封圈，环形密封圈的外周与阀壳111相抵。阀壳111和阀芯13上均设密封圈117，密封圈117随阀壳的移动实时密封。
实施例七
目前洗衣机中已有设置为墨盒式的储液盒，通常在洗衣机中安装储液盒的位置设置导液插接单元，通过导液插接单元将储液盒内的添加剂导出。通常导液插接单元设置为可插接入储液盒内的结构，插接入储液盒内的部分可吸收储液盒内的添加剂，并通过泵送等方式将储液盒内的添加剂导出进行投放。而当储液盒需要被清洗或被更换时，可移出储液盒，储液盒与导液插接单元相分离，在此过程中可能导致导液插接单元中残留的添加剂可能流出，并且部分遗留在导液插接单元上的添加剂将可能会影响导液插接单元位置的卫生、可能滋生细菌。为此，本发明提供了一种新的储液盒导液结构，能够保证当移出储液盒时，导液插接单元中的添加剂不会外泄。
如图20中所示，本发明提供的储液盒导液结构，导液插接单元403中设置供添加剂吸出的导液通道，导液通道中设置控制其导通或封闭的第一止逆阀404。通过第一止逆阀404的设置，使得可控制导液插接单元403中的添加剂是否可流出。进而可在需要封闭导液插接单元403时使导液通道被关闭，避免导液插接单元403出现添加剂外泄的情况。
储液盒1中设置与外界相连通的输出通道，输出通道内设置控制其导通或封闭的第二止逆阀402。导液插接单元403通常设置在安装储液盒1的位置处，储液盒1的输出通道中设置与外界相连通的开口417，当储液盒1固定在洗衣机中时，导液插接单元403的导液通道插接入储液盒1的输出通道中。并且导液通道与输出通道相连通，第一止逆阀404、第二止逆阀402相对设置，第一止逆阀404、第二止逆阀402相抵接并触发两者导通。即相对设置的第一止逆阀404、第二止逆阀402相互抵接后可相互顶开。使得储液盒1的输出通道中的添加剂可由导液插接单元403中的导液通道吸出。具体地，在安装储液盒1的过程中，第二止逆阀402随着储液盒1共同运动，导致第一止逆阀404向着靠近导液插接单元403的方向移动。储液盒1安装到位后，第一止逆阀404、第二止逆阀402相抵接，即第一止逆阀404、第二止逆阀402两者相互顶开而使第一止逆阀404、第二止逆阀402均处于导通的状态。添加剂可由输出通道流向导液通道。
而相反的，如图22中所示，当需要移出储液盒1时，应当通过移动储液盒1使导液插接单元403与储液盒1相分离；即储液盒1应当至少可沿导液插接单元403延伸方向移出。储液盒1与导液插接单元403相分离，使得导液插接单元403的导液通道由储液盒1的输出通道中移出，进而使第一止逆阀404、第二止逆阀402相分离。第一止逆阀40、第二止逆阀402不再抵接，两者之间相互顶开的力消失，故第一止逆阀404、第二止逆阀402均封闭各自所在的通道。即当需要移出储液盒1时，储液盒1向远离导液插接单元403的方向移动，导致储液盒1的第二止逆阀402和导液插接单元403的第一止逆阀404相分离，进而两者不再相互顶开，故第一止逆阀404、第二止逆阀402失去顶开的作用力，导致第一止逆阀404、第二止逆阀402均处于封闭的状态。第二止逆阀402封闭输出通道，使添加剂无法流入储液盒1内；第一止逆阀404使导液通道被封闭，进而使得添加剂无法从导液插接单元403中流出，进而避免导液插接单元403中的添加剂外泄。
具体地，储液盒1的输出通道设置与外界相连通的开口417，导液插接单元403的导液通道由开口417插入输出通道内，导液通道插入输出通道内的部分设置吸液口418，吸液口418与输出通道相连通。即添加剂由导液通道的吸液口418吸入，并被导液插接单元403导出。
如图20、21中所示，储液盒1的开口417处设置向储液盒1外部凸出的安装槽405，安 装槽405内嵌安装套406，可利用安装套406固定第一止逆阀404、第二止逆阀402。安装套406如图中所示，沿储液盒1轴向向其内部延伸，为圆环形内部中空的套题结构，安装套406内一端设置第二止逆阀402，即安装套406的远离导液插接单元403的端部构成第二止逆阀402的外壳。所述外壳内部固定第二止逆阀402的内部结构。安装套406中第二止逆阀402的靠近导液插接单元403的端部设置中空内腔407，第一止逆阀404可对应插接内嵌在中空内腔407中。利用安装套406不仅可以固定第二止逆阀402，并且可使第一止逆阀404内嵌在安装套406内，即利用安装套406限定第一止逆阀404、第二止逆阀402的运动方向。
安装套406与安装槽405的具体连接结构如图中20、21中所示。安装套406靠近导液插接单元403的端部设置向安装槽405外部弯折的翻边408，安装槽405卡嵌在翻边408与安装套406本体之间的间隙中。即利用翻边408与安装槽405的卡嵌配合实现安装套406的安装。具体如图中所示，可在安装槽405上和翻边408上相对的位置处设置可相互卡嵌配合的结构，利用卡嵌配合结构实现将安装套406与安装槽405相固定。由于安装套406内嵌第一止逆阀404、第二止逆阀402，即安装套406需要承受一定的重量，则为了保证安装套406与安装槽405的稳定连接，则安装套406与安装槽405必须稳定的固定，故翻边408需要延伸较长的长度。如图中所示，翻边408延伸至安装槽405靠近储液盒1开口的底端，即使翻边408与安装槽405相互配合的部分长度较长，使翻边408与安装槽405不易轻易脱落。
如图中所示，安装套406内嵌在安装槽405内部的部分设置由安装套406本体向安装槽405凸出的限位凸起409，限位凸起409、安装套406本体与安装槽405之间构成限位空间，在此限位空间内嵌密封圈117。通过密封圈117的设置，使得可保证安装套406与安装套406之间的紧密连接，防止两者分离。
如图中所示，安装槽405中内嵌导液槽11，导液槽11沿储液盒1的轴向延伸；通过导液槽11的设置，使得流入储液盒1内的添加剂可在导液槽11内流动，进而限定添加剂可在导液槽11内稳定的流动。导液槽11内部具有中空的安装腔，安装套406内嵌在安装腔内。即导液槽11的内部还包裹了安装套406，通过导液槽11、安装套406的两者结构的设置，进一步保证了第一止逆阀404、第二止逆阀402的稳定连接。导液槽11的安装腔连接内部中空、引导添加剂流动的引流管412。具体地，安装套406内嵌在安装腔内，安装套406内嵌的第二止逆阀402的部分结构可穿过安装套406、伸入安装腔与安装套406之间形成空隙空间413。所述空隙空间413除中部留有可内嵌第二止逆阀402部分结构的开口外的其余空间设置引导结构。使得利用引导结构可限定第二止逆阀402的第二阀芯414的移动，其中引导结构上还可设置供添加剂流过的孔，使得添加剂可透过引导结构。安装腔与引流管412均是两端开口、内部中空的腔体结构，安装腔靠近第一止逆阀404的开口与引流管412的一端开口相连。即通过安装腔与引流管412连接，第二止逆阀402、第一止逆阀404内嵌在安装腔内，使得经过第二止逆阀402、第一止逆阀404的控制，使得添加剂可由导液槽11、流入输出通道并流入导液通道内，最终由导液通道内流出。
具体地，第一止逆阀404、第二止逆阀402的具体结构如图中所示，第一止逆阀404中设置第一阀芯15，第二止逆阀402中设置第二阀芯414，第一阀芯415、第二阀芯414相对设置，且第一阀芯415、第二阀芯414相对的端部可相抵接或相分离。即当第一止逆阀404、第二止逆阀402相互抵接接触时，第一阀芯415、第二阀芯414在所述相对的端部相抵接，并且第一阀芯415、第二阀芯414相互顶开，导致第一止逆阀404、第二止逆阀402被导通。即第一阀芯415、第二阀芯414同轴、相对设置。
第一止逆阀404中、第一阀芯415指向其导通方向的外侧设置弹簧，第二止逆阀402中，第二阀芯414指向其导通方向的外侧设置弹簧。第一阀芯415、第二阀芯414在相互顶开后，第一阀芯415、第二阀芯414将会挤压各自侧的弹簧。而当第一止逆阀404、第二止逆阀402相互分离的情况下。第一阀芯415、第二阀芯414逐渐相互分离，两者之间相互顶开的力消失，故第一阀芯415、第二阀芯414将会在各自的压缩弹簧的作用下各自复位，进而导致第 一止逆阀404、第二止逆阀402被封堵。
进一步优选地，如图中所示，第一阀芯415上设置推针416，推针416沿指向第二阀芯414的方向延伸；第一阀芯415、第二阀芯414相抵接接触，推针416抵接推动第二阀芯414，即第一阀芯415通过推针416抵接推动第二阀芯414。故第一阀芯415可设置为内部具有中空空间的阀体结构，推针416内嵌在第一阀芯415的中空空间内。即由于利用推针416推动第二止逆阀402，故可将第一止逆阀404内的结构设置为内嵌推针416的中空结构，使得第一止逆阀404的结构比较节省材料。
进一步优选地，如图21中所示，可将第一阀芯415设置为内部具有推针416的阀芯结构，推针416的外部套设与推针416同轴的滑套，推针416可随第一阀芯415共同运动。在第二阀芯414上与推针416相对的位置设置供第二阀芯414伸入的插接槽419。当安装储液盒1时，第一阀芯415的推针416对应插入插接槽419中，并通过推针416顶开第二阀芯414。具体地，滑套可相应加工的尺寸较大，使得安装储液盒1时，第二阀芯414的部分结构可伸入滑套中，并且使阀针16对应插入插接槽419中，可达到上述的使第一阀芯415推动第二阀芯414运动的效果。
本发明提供的储液盒导液结构，在导液插接单元403上设置了第一止逆阀404，可通过第一止逆阀404控制导液插接单元403中的添加剂是否流出，进而避免导液插接单元403中的添加剂出现外泄的情况。并且在储液盒的投放口处设置第二止逆阀402，通过第一止逆阀404、第二止逆阀402之间相对设置，使得安装储液盒1时、随着储液盒1的移动，第一止逆阀404、第二止逆阀402相互顶开导通，进而控制添加剂由导液插接单元403流向储液盒1内。而当移出储液盒1时、随着储液盒1的移动，第一止逆阀404、第二止逆阀402相互分离并均封闭，进而控制导液插接单元403中的添加剂不会外泄，且添加剂也不会再流向储液盒1内，达到避免导液插接单元403的添加剂外流的效果。
如图23中所示，洗衣机中设置投放装置，投放装置中至少具有一个插接槽，投放结构包括安装于插接槽内的储液盒1，插接槽中设置导液插接单元403，储液盒1在插接槽内安装到位后，导液插接单元403将会与储液盒1相插接配合；当需要拆出储液盒1时，导液插接单元403将会与储液盒1相分离。即本发明所述的储液盒1、导液插接单元403设置在洗衣机用以投放添加剂的投放装置中。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
