  • the present invention relates to a faucet valve core, and in particular to a 0-degree closing (water inlet) valve core and a pull-out faucet that has both water mixing (controlling the opening and closing of a water inlet channel and adjusting water temperature) and water distribution (distributing a water outlet channel for water flow) functions.
  • Faucet valve cores can be divided into two categories according to their functions.
  • One is the water mixing valve core, which is used to control the opening and closing of the water inlet of cold water and hot water and adjust the water temperature. Some water mixing valve cores can also adjust the water volume.
  • the other is the water diversion valve core, which can control the water flow direction and distribute the water outlet channel. Due to the limitations of the functions of the two types of valve cores, in the bathroom industry, the two types of valve cores are often used in combination to achieve the functions of water diversion, water temperature and flow adjustment. In this way, not only one more valve core is needed, but also the two types of valve cores are in the faucet body at the same time, making the faucet body structure complex, bulky, wasteful of copper materials, and difficult to process.

Description

阀芯及抽拉式水龙头 技术领域
本发明涉及一种水龙头阀芯，尤其涉及一种兼具混水(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)功能且0度关闭(进水)阀芯以及一种抽拉式水龙头。
背景技术
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。由于两类阀芯功能的局限性，在卫浴行业，往往是两类阀芯组合使用以实现分水、调节水温和流量的功能，这样一来不仅需要多使用一个阀芯，而且两类阀芯同时在水龙头主体内，使得水龙头主体结构复杂、体积庞大、浪费铜材、加工难度大。如专利号为CN203718041U(专利号ZL201320478247.5)的中国实用新型专利《一种淋浴水龙头》就披露这样一种采用两种阀芯的水龙头结构。
分水阀芯因喷淋系统不同，分为两水路分水(花洒和水龙头)和三水路分水(花洒、顶喷和水龙头)两种。目前市场上也有将两个阀芯功能合二为一的水龙头阀芯，如专利号为CN102644766A(申请号ZL201210101026.6)的中国发明专利申请《分水、混水一体式多功能陶瓷阀芯》就公开了这样一种陶瓷阀芯，包括壳体和底座，壳体内部由上到下依次设有拨杆、卡装固定在拨盘上的陶瓷动片和卡装在底座上的陶瓷静片，拨杆上端伸出壳体顶部，中部设于支架内，并通过固定在支架上的支轴与支架枢接，支架下端连接有拨盘，拨杆末端与拨盘连接并带动拨盘在拨杆的拨动方向沿支架滑动，底座上设有相互分隔的第一、二进水口和第一、二出水口，陶瓷静片上设有与之相对应的第一、二、三、四过流通道；所述陶瓷动片顶端密封，底端的中部向内凹陷，形成用于连通进、出水口的混流腔，底端端面与陶瓷静片顶部贴合，形成用于改变进、出水流向和流量的切换面。
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
本发明所要解决的技术问题是针对上述现有技术现状而提供一种布局合理紧凑的阀芯，通过阀柄的转动阀芯能实现混水(控制进水水路启闭、调节水温)，通过阀柄的摆动阀芯能实现分水(分配水流的出水通道)，且阀柄只能在其处于初始位置时进行摆动从而关闭出水。
本发明解决上述技术问题所采用的技术方案为：一种阀芯，包括阀壳、阀柄及安装在阀壳内的转子、拨盘、动阀片和定阀片，所述阀柄能转动而驱动转子及拨盘转动，且阀柄能摆动而驱动拨盘移动；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内的底部，所述动阀片的旋转用于调节冷水、热水混合比例，所述动阀片的滑移用以切换不同的出水通道、以及用以关闭进水；其特征在于：所述拨盘上设有限位部，所述阀壳的内顶部设有两沿圆周间隔的内凸台，两个所述内凸台之间形成与所述限位部相配的限位槽，在限位部与限位槽对齐状态下，所述动阀片才能随拨盘往关闭进水方向滑移，限位部外露出转子侧部并插入限位槽；在拨盘转动至限位部与限位槽错位状态下，所述限位部被内凸台阻挡而使动阀片不能随拨盘往关闭进水方向滑移。
作为阀芯内通道的具体设置方式，上述阀壳底部和定阀片上均设有位置对应的冷水通道、热水通道、第一出水通道和第二出水通道，所述动阀片内设有混水腔，所述动阀片的旋转能使所述混水腔与冷水通道和热水通道的重合面积发生变化，所述动阀片的滑移能使所述混水腔选择与第一出水通道或第二出水通道连通，动阀片的滑移还能决定动阀片封堵住所述冷水通道和热水通道与否。一般以两出水通道为最佳，当然也可设计出更多出水通道。动阀片封堵住冷水通道和热水通道，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，更利于布局。
若要动阀片移动至第二出水通道出水的位置时，保证第一出水通道没有水流出，则需要对第一出水通道进行封堵的面积比较大，在有限的布局空间内，这就需要将第一出水通道的横截面做小，导致第一出水通道的出水过小；或将动阀片遮盖面做大，也就意味需要将阀芯做大。无论哪种方式都有缺陷。
针对这一现状，进一步改进，上述动阀片内设有与混水腔连通的第一混水出口和第二混水出口，所述第一混水出口始终与第一出水通道连通，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。该结构使得无论动阀片移动切换从哪个出水通道流出时，其第一出水通道必定有水流出，切换出水位置的目的是在控制第一出水通道出水与否的电磁阀损坏时，可以切换第二出水通道出水，一般情况下，电磁阀损坏，则始终处于关闭位置，此时就算有水流进入第一出水通道也没有影响，而本方案因不考虑在第二出水通道出水时必须阻挡第一出水通道，故在空间一定的情况下能将第一出水通道的出水面积尽可能做大，从而保证出水量大。
作为优选，上述动阀片处于0度中间位置状态下，所述混水腔与冷水通道和第一出 水通道连通、而与热水通道和第二出水通道阻断；所述动阀片从0度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冷水通道和热水通道，冷水通道和热水通道均与混水腔阻断，限位部插入限位槽；所述动阀片从0度中间位置开始朝另一侧方向滑移，所述混水腔与冷水通道和第二出水通道连通、而与热水通道阻断，所述混水腔与第一出水通道连通或阻断。前述布局使得本阀芯具有三个清晰明确的工作位置，且该结构使得0度位置时中间位置状态下为全冷水状态，即从关闭到开启时先出冷水，避免烫手，使用更安全。
更进一步改进，上述拨盘的顶面设有向上凸起的导向台，所述限位部设于导向台的一侧，所述转子的底部设有与所述限位部匹配的导向凹槽，所述导向台置于导向凹槽内并能滑移。导向台与导向凹槽的配合确保动阀片随拨盘径向滑移更平稳。
进一步改进，上述导向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，才能使得动阀片随拨盘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，该结构使水道流出切换过程中有一定手感，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。
作为优选布局，上述第一混水出口设于动阀片底面的中心位置，所述第二混水出口与第一混水出口之间通过封堵壁隔断，封堵壁位于第二出水通道上方状态下阻断第二混水出口与第二出水通道连通。该结构布局利于动阀片的滑移和转动实现位置的切换。
作为改进，上述拨盘通过卡扣的方式固定在动阀片的顶部，拨盘和动阀片之间设有第一密封件，所述动阀片上设有顶部开口的凹腔，所述拨盘的底面将凹腔的顶部开口遮盖形成所述混水腔；动阀片上设置的顶部开口的凹腔，使得动阀片加工成型更方便，利于混水腔的形成。
作为优选布局，上述第一出水通道位于中心，所述冷水通道、热水通道及第二出水通道围绕所述第一出水通道周缘布置；该结构布局利于动阀片的滑移和转动实现位置的切换。所述阀柄的中部通过销轴与转子转动连接，阀柄的上端从阀壳的顶部伸出，阀柄的下端插入拨盘的顶部凹腔内。本结构使得阀柄不仅能带动转子、拨盘和动阀片同步旋转，通过阀柄的摆动，还能带动拨盘、动阀片相对转子和定阀片径向滑移。
作为改进，上述转子的侧壁具有侧凸出的限位块，所述限位块位于两块内凸块之间，以对转子的转动角度进行限位。该结构对转子的转动角度进行限位，在其中一个极限角度位置，限位块与其中一块内凸台挡配，冷水通道完全与混水进口导通；另一个极限角度位置，限位块与另一块内凸台挡配，热水通道完全与混水进口导通。
作为改进，上述阀壳由上壳体和底座卡接组成，底座构成阀壳的底部，定阀片卡接在底座上，两个所述内凸台设于壳体内顶壁的周缘，所述定阀片和底座之间设有第二密 封件。前述阀壳结构便于在阀壳内组装各部件，阀壳也可以是一体构件。
与现有技术相比，本阀芯的优点在于：限位部和限位槽的设置，使得只有在限位部与限位槽对齐状态下，动阀片才能随拨盘往关闭进水方向滑移，限位部外露出转子侧部并插入限位槽，而当拨盘转动至限位部与限位槽错位状态下，限位部被内凸台约束而使动阀片不能随拨盘往关闭进水方向滑移。即本阀芯只能在初始位置(安装在阀柄上的把手处于数值向下没有偏转的位置)才能被关闭，利于使用者识别关闭状态。
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结构布局紧凑合理、电控模式和手动模式可切换的抽拉式水龙头。
本发明解决上述第二个技术问题所采用的技术方案为：一种抽拉式水龙头，包括龙头外壳、出水嘴、龙头把手和出水管；其特征在于：龙头外壳内设有基座和所述的二进二出阀芯，所述龙头把手与所述阀柄连接；阀壳固定在基座上，基座具有第一初始进水通道、第二初始进水通道、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，所述第一初始进水通道与冷水通道接通，所述第二初始进水通道与热水通道导通；所述第二过渡出水通道与总出水通道、第二出水通道始终导通，所述第一出水通道与第一过渡出水通道接通，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。
作为优选，上述总出水通道、第一初始进水通道与第二初始进水通道的接口端均设于基座的下端面上并朝下设置，电控开关设于基座的上端，水管一端连接在总出水通道的端口，出水管的另一端向上弯折并与位于基座上方的所述出水嘴连接；龙头外壳内设有控制模块，电控开关与所述控制模块连接，控制模块的感应部显露出龙头外壳。
进一步改进，上述基座上还设有供出水管活动穿设的引导槽，引导槽的设置保证出水管在抽拉过程中沿预设轨迹移动，不易发生绕线。龙头外壳包括与台盆固定的基壳及插接在基壳上的引导管，所述基座、控制模块和所述双水路阀芯设于基壳内，出水嘴可脱卸连接在引导管的前端。引导管将水路向上引导，适合用于厨房龙头。
为方便安装电控开关，所述基座的上端设有安装腔，电控开关安装在安装腔内，第一过渡出水通道和总出水通道之间具有阀口，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。
为方便将双水路阀芯直接安装到基座上，基座的侧部具有阀芯安装面，阀壳安装在所述阀芯安装面上，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，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，双水路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。
与现有技术相比，本手拉式水龙头的优点在于：该厨房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，双水路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或通路，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，只要操作双水路阀(转动龙头把手)将阀芯的两个出水通道均切断，没有水流流出。另，总出水通道、初始进水通道设于基座的下端面上并朝下设置，电控开关设于基座的上端，出水管一端连接在总出水通道的端口，出水管另一端向上弯折并与位于基座上方的出水嘴连接。出水管从下端开始并弯折后向上延伸，适合做成抽拉式厨房龙头。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。

具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1～16所示，为0度关闭的二进二出阀芯的优选实施例。
一种0度关闭的二进二出阀芯，包括阀壳1、阀柄4及安装在阀壳内的转子2、拨盘3、动阀片5和定阀片6，拨盘3约束在转子2底部能随转子2一起旋转、且能相对转子2滑移，阀柄4的中部通过销轴41与转子2转动连接，阀柄4的上端从阀壳1的顶部伸出，阀柄4的下端插入拨盘3的顶部凹腔32内。
动阀片5固定在拨盘3的底面，定阀片6固定在阀壳1内的底部，动阀片5的旋转用于调节冷水、热水混合比例，动阀片5的滑移用以切换不同的出水通道、以及用以关闭进水。阀壳1底部和定阀片6上均设有位置对应的冷水通道7a、热水通道7b、第一出水通道7c和第二出水通道7d，动阀片5内设有混水腔51，动阀片5的旋转能使所述混水腔51与冷水通道7a和热水通道7b的重合面积发生变化，动阀片5的滑移能使所述混水腔51选择与第一出水通道7c或第二出水通道7d连通，动阀片5的滑移还能决定动阀片5封堵住所述冷水通道7a和热水通道7b与否。
阀壳1由上壳体11和底座12卡接组成，底座12构成阀壳1的底部，定阀片6卡接在底座12上，两个所述内凸台设于壳体内顶壁的周缘，定阀片6和底座12之间设有第二密封件9b。
拨盘3上设有限位部31，阀壳1的内顶部设有两沿圆周间隔的内凸台1a，两个所述内凸台1a之间形成与所述限位部31相配的限位槽1b，在限位部31与限位槽1b对齐状态下，所述动阀片5才能随拨盘3往关闭进水方向滑移，限位部31外露出转子2侧部并插入限位槽1b；在拨盘3转动至限位部31与限位槽1b错位状态下，限位部31被内凸台1a阻挡而使动阀片5不能随拨盘3往关闭进水方向滑移。
动阀片5内设有与混水腔51连通的第一混水出口511和第二混水出口512，第一混水出口512始终与第一出水通道7c连通，动阀片5的滑移能决定所述第二混水出口513与第二出水通道7d连通与否。第一混水出口511设于动阀片5底面的中心位置，第二混水出口512与第一混水出口511之间通过封堵壁52隔断，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。
动阀片5处于0度中间位置状态下，所述混水腔51与冷水通道7a和第一出水通道7c连通、而与热水通道7b和第二出水通道7d阻断；所述动阀片5从0度中间位置开始朝一侧方向滑移，能使动阀片5的底面同时封堵住所述冷水通道7a和热水通道7b，冷水通道7a和热水通道7b均与混水腔51阻断，限位部31插入限位槽1b；所述动阀片5从0度中间位置开始朝另一侧方向滑移，所述混水腔51与冷水通道7a和第二出水通道7d连通、而与热水通道7b阻断，所述混水腔51与第一出水通道7c连通或阻断。
拨盘3的顶面设有向上凸起的导向台32，限位部31设于导向台32的一侧，所述转子2的底部设有与所述限位部31匹配的导向凹槽21，所述导向台32置于导向凹槽21内并能滑移，导向台32的前后壁上插设有周壁部分显露出来的第一柱8a，所述导向凹槽21的前后内壁上插设有周壁部分显露出来的第二柱8b，所述第一柱8a需要越过第二柱8b，才能使得动阀片5随拨盘3从一侧位置进入至另一侧位置。
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9a，所述动阀片5上设有顶部开口的凹腔，拨盘3的底面将凹腔的顶部开口遮盖形成所述混水腔51；所述第一出水通道7c位于中心，冷水通道7a、热水通道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的侧壁具有侧凸出的限位块22，所述限位块22位于两块所述内凸台1a之间，以对转子2的转动角度进行限位。
本0度关闭的二进二出阀芯的工作原理及过程如下：
如图3、4、10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0度的中间位置状态，混水腔51与冷水通道7a和第一出水通道7c连通、而与热水通道7b和第二出水通道7d阻断，冷水通过冷水通道7a、混水腔51后从第一出水通道7c流出，第二出水通道7d没有水流出，即为全冷水状态；如图5、11、12所示，动阀片5的旋转能使混水腔51与冷水通道7a和/或热水通道7b连通，即动阀片5的旋转调节冷水、热水混合比例，实现水流温度的调节。
如图5、8、12所示，动阀片5处于0度中间位置状态下，限位部31才能与限位槽1b对齐，阀柄4带动动阀片5随拨盘3从0度中间位置开始朝一侧方向滑移，限位槽1b能对拨盘3的移动进行让位，限位部31插入限位槽1b，能使动阀片5的封堵壁52同时封堵住冷水通道7a和热水通道7b，冷水通道7a和热水通道7b均与混水腔51阻断，因此第一出水通道7c和第二出水通道7d均没有水流出，此时为水流关闭状态。
如图8、9所示，阀柄4带动动阀片5随拨盘3从0度中间位置开始朝另一侧方向滑移，动阀片5的底面没有封堵住冷水通道7a，混水腔51与冷水通道7a、第一出水通道7c和第二出水通道7d连通、而与热水通道7b阻断，冷水分两路流出，一路经由混 水腔51后从第一出水通道7c流出，另一路经由混水腔51后从第二出水通道7d流出，即为全冷水状态；动阀片5的旋转能使混水腔51与冷水通道7a和/或热水通道7b连通，即动阀片5的旋转调节冷水、热水混合比例，实现水流温度的调节。
