Description

阀芯座及阀芯模块组 技术领域
本发明属于自动控制出水(感应出水)的水龙头的技术领域，尤其涉及一种用于自动控制出水水龙头的阀芯座，还涉及一种兼具混水(控制进水水路启闭、调节水温)功能和分水(分配水流的出水通道)功能的具有前述阀芯座的阀芯模块组。
背景技术
现有水龙头的出水控制主要有两种方法，一种是通过把手手动控制出水，另一种是通过感应组件收发信号进而控制电控开关譬如电磁阀开关实现控制出水。由于感应水龙头不需要接触龙头本体即可实现水龙头的开关，不仅使用方便，而且有利于保持龙头表面干净。感应水龙头又存在两种模式。一种是长出水模式，感应一次打开水龙头，再次感应关闭水龙头。另一种是感应出水模式，设定打开水龙头的条件，当满足条件时打开，不满足条件时关闭。例如，在预定位置感应到物体时打开水龙头，在预定位没有感应到物体时关闭水龙头；或者，当检测到龙头把手或出水口离开预定位置时打开水龙头，检测到龙头把手或出水口处于预定位置时关闭水龙头。
无论何种感应水龙头，均存在以下缺陷，当电磁阀开关损坏后，就不能感应出水或者水龙头始终保持常流水状态，无法正常使用，这就需要更换水龙头，增加使用成本。
也有的感应水龙头，与阀芯结合，阀芯为多功能阀芯，多功能阀芯能调节水温及关闭水路，如申请号CN202110341610.8(公开号为CN112963608A)的中国发明专利申请《一种感应水龙头及其控制方法》就披露这样一种感应水龙头结构。然前述感应水龙头依旧存在在电磁阀开关损坏后，不能感应出水的缺陷。
水龙头阀芯按功能可以分为两大类，一类是混水阀芯，用以控制冷水、热水的进水水路启闭、调节水温，也有的混水阀芯还可以调节水量。另一类是分水阀芯，可以控制水流向、分配水流的出水通道。
目前也有将两个阀芯功能合二为一的水龙头阀芯，如申请号CN201210101026.6的中国发明专利申请《分水、混水一体式多功能陶瓷阀芯》就公开了这样一种阀芯。前述专利只能通过陶瓷动片实现第一、二出水口的关闭，或第一、二出水口的选择通路，即第一、二出水口两者只能有一个通水，或者都不通水。且陶瓷动片通过其内的混流腔与第一、二出水口的选择导通实现分水功能。
发明内容
本发明所要解决的第一个技术问题是针对上述现有技术现状而提供一种用于感应水龙头的阀芯座，为实现采用该阀芯座的水龙头在电控开关损坏后可将其变换为普通水龙头使用提供可能，从而使得水龙头在电控开关损坏后仍然可以正常使用。
本发明解决上述第一个技术问题所采用的技术方案为：一种阀芯座，包括基座，其特征在于：所述基座具有总出水通道、彼此独立布置的第一过渡出水通道和第二过渡出水通道，所述第二过渡出水通道与总出水通道始终导通，所述第一过渡出水通道和总出水通道之间设有电控开关，该电控开关用以控制第一过渡出水通道和总出水通道导通与否。
为方便将水路切换阀芯直接安装到基座上，上述基座上具有阀芯安装面，所述第一过渡出水通道和第二过渡出水通道贯通所述阀芯安装面；所述基座内还设有初始进水通道，所述初始进水通道贯通所述阀芯安装面。当然水路切换阀芯也可以不直接安装在基座上，只要将第一过渡出水通道和第二过渡出水通道分别对应与水路切换阀芯的第一出水通道和第二出水通道连通、将初始进水通道与水路切换阀芯的进水通道连通即可，连通可以采用水管连接。
为方便安装电控开关，上述基座内设有安装腔，所述电控开关安装在该安装腔内，所述第一过渡出水通道和总出水通道之间具有阀口，所述电控开关在常态下封堵住所述阀口以隔断第一过渡出水通道和总出水通道，得电则电控开关打开所述阀口以使得第一过渡出水通道和总出水通道导通。电控开关可以采用最为常见的电磁阀开关。
与现有技术相比，本阀芯座的优点在于：该阀芯座可以与水路切换阀配合，正常状态下，第一过渡出水通道通水，总出水由电控开关(如电磁阀开关或电动开关)控制，这就可以实现自动出水(如感应出水)；若电控开关损坏，电控开关始终将第一过渡出水通道和总出水通道阻断，这时只需要通过操作水路切换阀将水路切换至使得第二过渡出水通道出水，水流可直接从总出水通道流出，关水时，只要操作水路切换阀将第二过渡出水通道阻断。为此本阀芯座为采用该阀芯座的水龙头在电控开关损坏后可将其变换为普通水龙头使用提供可能，使得在水龙头在电控开关损坏后仍然可以正常使用，从而避免了一旦电控开关损坏水龙头就无法出水、无水可用的尴尬情况出现。
本发明所要解决的第二个技术问题是针对上述现有技术现状而提供一种用于感应水龙头的阀芯模块组，采用该阀芯模块组的水龙头在电控开关损坏后可将其切换为普通水龙头正常使用。
本发明解决上述第二个技术问题所采用的技术方案为：一种阀芯模块组，包括水路切换阀芯，所述水路切换阀芯包括进水通道、第一出水通道、第二出水通道、阀壳，阀壳内设有阀片及用以操作阀片动作的阀柄，所述阀片的动作能使得水流从第一出水通道和/或第二出水通道流出；其特征在于：还包括如前述的阀芯座，所述阀壳固定在基座 上，所述第一出水通道与第一过渡出水通道接通，所述第二出水通道与第二过渡出水通道接通。
为方便将水路切换阀芯直接安装到基座上，上述基座上具有阀芯安装面，所述阀壳安装在所述阀芯安装面上，所述第一过渡出水通道和第二过渡出水通道贯通所述阀芯安装面，所述第一出水通道和第二出水通道的出口端设于阀壳的底面。阀芯安装面上还可以设有两个定位孔，阀壳的底部设置与定位孔匹配的定位柱，水路切换阀芯定位在阀芯安装面上后，再将整体压制在水龙头外壳内即可。第一出水通道和第二出水通道的出水口设于阀壳的底面，使得出水通道与过渡出水通道的衔接无需额外的水管连接，整体结构紧凑可靠。
进一步改进，上述阀芯座内还设有初始进水通道，所述初始进水通道贯通所述阀芯安装面，所述进水通道的进口端设于阀壳的底面，所述初始进水通道与所述进水通道接通。初始进水通道设于基座上可以使得整体结构更紧凑，无效在额外地方设置进水通道，采用该阀芯模块组的水龙头内部接管更方便。
为使得切换阀芯兼具混水功能(调节水温功能)，上述初始进水通道有两个，分别为第一初始进水通道和第二初始进水通道，所述进水通道有两个，分别为第一进水通道和第二进水通道，所述第一初始进水通道与第一进水通道接通，所述第二初始进水通道与第二进水通道导通，所述阀片具有混水腔，阀片的动作能实现混水腔与第一进水通道和/或第二进水通道连通。也即本切换阀芯兼具混水和分水功能，这种阀芯市场上有多种形式，可以是双轴阀芯，可参考背景专利，也可以是单轴阀芯，可参考本申请人以前申请的系列专利。
进一步改进，上述水路切换阀芯还包括安装在阀壳内的转子、拨盘，所述阀片包括动阀片和定阀片，所述拨盘约束在转子底部能随转子一起旋转、且能相对转子滑移，所述动阀片固定在拨盘的底面，所述定阀片固定在阀壳的底部，所述第一进水通道、第二进水通道、第一出水通道和第二出水通道设于所述阀壳底部和定阀片上；所述动阀片内设有混水腔，动阀片的底面设有与混水腔连通的混水进口、第一混水出口和第二混水出口，所述动阀片的旋转能使所述混水腔通过混水进口与第一进水通道和/或第二进水通道连通，使得第一进水通道和第二进水通道的过水面积实现调节，完成混水温度的调节；第一混水出口始终与第一出水通道连通，所述动阀片的滑移能决定所述第二混水出口与第二出水通道连通与否，及决定动阀片封堵住所述第一进水通道和第二进水通道与否。
该结构使得动阀片的滑移能实现两种位置，第一位置为第一混水出口与第一出水通道连通，第二混水出口被动阀片阻断与第二出水通道连通，该状态只有第一出水通道出水；第二位置为第二混水出口与第二出水通道连通，而第一混水出口与第一出水通道始终连通，该状态第一出水通道和第二出水通道均出水；第三位置为动阀片封堵住第一进 水通道和第二进水通道，此时第一出水通道和第二出水通道均不出水，与传统封堵住第一出水通道和第二出水通道的方式不同。
作为优选的布局，上述动阀片处于中间位置状态下，所述动阀片的底面没有封堵住所述第一进水通道和第二进水通道，所述动阀片的旋转能使所述混水腔与第一进水通道和/或第二进水通道连通，所述动阀片的底面阻断第二混水出口与第二出水通道连通；
所述动阀片从中间位置开始朝一侧方向滑移，能使动阀片的底面同时封堵住所述第一进水通道和第二进水通道，第一进水通道和第二进水通道均与混水进口阻断；
所述动阀片从中间位置开始朝另一侧方向滑移，动阀片的底面没有封堵住所述第一进水通道和第二进水通道，所述动阀片的旋转能使所述混水腔与第一进水通道和/或第二进水通道连通，所述第二混水出口与第二出水通道连通。
前述布局使得本阀芯具有三个清晰明确的工作位置。第一位置为中间位置，该位置混水经由混水腔、第一混水出口后从第一出水通道流出，动阀片的旋转能调节水流温度；第二位置为动阀片从中间位置滑移至一侧，该位置因动阀片的底面同时封堵住所述第一进水通道和第二进水通道，因此第一出水通道和第二出水通道均没有水流出，此时为水流关闭状态；第三位置为动阀片从中间位置滑移至另一侧，混水分两路流出，一路经由混水腔、第一混水出口后从第一出水通道流出，另一路经由混水腔、第二混水出口后从第二出水通道流出，另外，动阀片的旋转能调节水流温度。
为确保动阀片相对转子径向滑移平稳，上述拨盘的顶面还设有导向凸台，所述转子的底部设有与所述导向凸台匹配的导向凹槽，导向凸台置于导向凹槽内并能滑移，导向凸台与导向凹槽的配合实现滑移导向。
更进一步改进，上述导向凸台的前后壁上插设有周壁部分显露出来的第一柱，所述导向凹槽的前后内壁上插设有周壁部分显露出来的第二柱，所述第一柱需要越过第二柱，才能使得动阀片从一侧位置进入至另一侧位置。第一柱和第二柱有部分错位，需要一定的力才能使第一柱越过第二柱，该结构使得从单水道流出切换至双水道流出的过程中提供一定的手感，从一个位置进入另一个位置，需要一定的力驱动阀柄才能实现，操作手感好；另外也明确指示使用者，在什么位置进行了模式切换。
与现有技术相比，本阀芯模块组的优点在于：采用该阀芯模块组的水龙头在电控开关损坏后可将其切换为普通水龙头使用。正常状态下，水路切换阀芯切换至水流经由第一出水通道与第一过渡出水通道流出，此时总出水由电控开关(如电磁阀开关)控制，这就可以实现自动出水(如感应出水)；若电控开关损坏，电控开关始终将第一过渡出水通道和总出水通道阻断，这时只需要通过操作水路切换阀将水路切换至使得水流经由第二出水通道后从第二过渡出水通道流出，而第二过渡出水通道与总出水通道直接导通，水流可直接从总出水通道流出，关水时，只要操作水路切换阀将第二过渡出水通道阻断。

第一混水出口512设于动阀片5底面的中心位置，所述混水进口511位于第一混水出口512的一侧且两者之间的底面直接贯通，所述第二混水出口513与第一混水出口512之间通过封堵壁52隔断，所述封堵壁52位于第二出水通道7d上方状态下阻断第二混水出口513与第二出水通道7d连通。
拨盘3通过卡扣的方式固定在动阀片5的顶部，拨盘3和动阀片5之间设有第一密封件14a，所述动阀片5上设有顶部开口的凹腔，所述拨盘3的底面将凹腔的顶部开口遮盖形成所述混水腔51。
第一出水通道7c位于中心，所述第一进水通道7a、第二进水通道7b及第二出水通道7d围绕所述第一出水通道7c周缘布置。
转子2的侧壁具有两块侧凸出的限位块22，所述阀壳1的内顶壁上设有两块径向凸起的阻挡块10，两块阻挡块10沿圆周间隔设置，所述限位块22位于两块阻挡块10之间，以对转子2的转动角度进行限位。
还包括阀芯座，阀芯座包括基座9，基座9具有总出水通道9a、彼此独立布置的第 一过渡出水通道9b和第二过渡出水通道9c，所述第二过渡出水通道9c与总出水通道9a直接导通，所述第一过渡出水通道9b和总出水通道9a之间设有电控开关13，该电控开关13用以控制第一过渡出水通道9b和总出水通道9a导通与否。
基座9上具有阀芯安装面91，阀壳1安装在所述阀芯安装面91上，阀芯安装面91上还可以设有两个定位孔94，阀壳1的底部设置与定位孔94匹配的定位柱15，水路切换阀芯定位在阀芯安装面91上后，再将整体压制在水龙头外壳内即可。

本阀芯模块组的工作原理及过程如下：
采用该阀芯模块组的水龙头在电控开关13损坏后可将其切换为普通水龙头使用。正常状态下，水路切换阀芯切换至水流经由第一出水通道7c与第一过渡出水通道9b流出，此时总出水通道9a的出水由电控开关13(如电磁阀开关)控制，这就可以实现自动出水(如感应出水)；若电控开关13损坏，电控开关13始终将第一过渡出水通道9b和总出水通道9a阻断，这时只需要通过操作水路切换阀将水路切换至使得水流经由第二出水通道9d后从第二过渡出水通道9c流出，而第二过渡出水通道9c与总出水通道9a直接导通，水流可直接从总出水通道9a流出，关水时，只要操作水路切换阀将第二过渡出水通道9c阻断。
本水路切换阀芯的工作原理及过程如下：
如图7、10、14所示，在阀柄4未前后摆动、未带动拨盘3和动阀片5径向滑移状态下(即阀柄4没有以销轴41为轴线转动)，动阀片5处于中间位置状态下，动阀片5的底面没有封堵住第一进水通道7a和第二进水通道7b，动阀片5的底面阻断第二混水出口513与第二出水通道7d连通，该位置混水经由混水腔51、第一混水出口512后从第一出水通道7c流出，第二出水通道7d没有水流出；动阀片5的旋转能使混水腔51与 第一进水通道7a和/或第二进水通道7b连通，即动阀片5的旋转能调节水流温度。
[根据细则91更正 22.03.2022]　
如图9、12、16所示，在阀柄4向右摆动最大幅度并带动拨盘3和动阀片5径向向左滑移状态下（即阀柄4以销轴41为轴线转动），动阀片5从中间位置开始朝一侧方向（图示方向的左侧）滑移，能使动阀片5的底面同时封堵住第一进水通道7a和第二进水通道7b，第一进水通道7a和第二进水通道7b均与混水进口511阻断，因此第一出水通道和第二出水通道均没有水流出，此时为水流关闭状态。
[根据细则91更正 22.03.2022]　
如图8、11、15所示，在阀柄4向左摆动最大幅度并带动拨盘3和动阀片5径向向右滑移状态下（即阀柄4以销轴41为轴线转动），动阀片5从中间位置开始朝另一侧方向（图示方向的右侧）滑移，动阀片5的底面没有封堵住第一进水通道7a和第二进水通道7b，第二混水出口513与第二出水通道7d连通，混水分两路流出，一路经由混水腔51、第一混水出口512后从第一出水通道7c流出，另一路经由混水腔51、第二混水出口513后从第二出水通道7d流出；动阀片5的旋转能使混水腔51与第一进水通道7a和/或第二进水通道7b连通，即动阀片5的旋转能调节水流温度。
