Description

一种防串水恒温水龙头 技术领域
本发明涉及卫浴设备，特别涉及一种防串水恒温水龙头。
背景技术
恒温水龙头是对出水水温及出水流量进行控制的卫浴设备，由于恒温水龙头能够自动调整冷热水混合比例，从而保证出水温度保持恒定，得到越来越广泛的使用。其中，管道式的恒温龙头由于整体横向设置，恒温阀芯和双控开关阀芯分别位于壳体两端，体积较小、较为简洁美观，越来越多地被使用在高端场所。为了防止恒温阀芯在没有使用时的串水问题，需要使用双控开关阀芯对冷、热水进水或者冷水进水、混合水出水或者热水进水、混合水出水进行同时控制。由于管道式的恒温龙头的结构特点导致其内部会至少存在三根及以上并排设置的流道，且这三根流道没有位于同一个平面。
如专利号为201510537858.6的中国专利公开了一种双路出水的恒温水龙头，能够有效防止恒温阀芯的串水现象同时控制出水流量。该恒温水龙头包括外壳和主阀体，主阀体一端安装有恒温阀芯另一端安装有分水阀芯，主阀体两端之间并排设置有多个流道，且流道并非直孔，用于连通恒温阀新和分水阀芯(如图1所示，径向截面上最多同时排列有5根沿轴线方向设置的流道并且这些流道没有处于同一个轴向平面上)。由于多个流道并排、重叠并没有位于同一平面，导致该主阀体加工困难。使用浇筑的方法进行加工。使用注塑方法进行加工时，两组芯杆需要从主阀体两端深入到主阀体内，拼合形成流道，对于模具、芯杆精度要求高，加工时较为麻烦。使用浇筑方法进行加工时，需要使用砂芯，多根流道并排、没有位于同一平面，导致无法采用一体式的砂芯，不然砂芯无法进行制造，需要使用多根砂芯拼接而成，这一方面砂芯生产、组装较为麻烦，生产成本高，另一方面又无法较好地保证砂芯之间的位置精度，影响主阀体内部流道的壁厚的均匀程度及强度。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种防串水恒温水龙头，整体结构较为简单，加工较为方便。
本发明的上述技术目的是通过以下技术方案得以实现的：一种防串水恒温水龙头，包括壳体,壳体内安装有恒温阀芯、双控开关阀芯，壳体上设置有第一进水通道、第二进水通道和第一出水通道，壳体一端设置有进水腔一、进水腔二以及混合出水腔,壳体另一端设置有开关阀芯腔，恒温阀芯插设在进水腔一、进水腔二及混合出水腔内，双 控开关阀芯安装开关阀芯腔内，其特征在于：恒温阀芯和双控开关阀芯之间设置有开关阀芯座，进水腔一与第一进水通道连接，双控开关阀芯包括第二进水口和设置在双控开关阀芯底面的第二出水口、混合水进口及混合水第一出口，第二进水通道与双控开关阀芯上的第二进水口连通，壳体上设置有第二过水腔和第二过水通道，第二过水通道连通第二过水腔及进水腔二，双控开关阀芯底面与开关阀芯座一端端面抵触密封，开关阀芯座上开设有连通流道一、连通通道二及连通通道三，连通通道一一端处于开关阀芯座端面与第二出水口连接，另一端与第二过水腔连通；连通通道二贯穿开关阀芯座两端面，连通混合水进口与混合水出水腔；连通通道三一端处于开关阀芯座端面与混合水第一出口，另一端与第一出水腔连通。
通过上述技术方案，在壳体内设置开关阀芯座，通过两者的分体设置，从而方便两个部件的加工。连通恒温阀芯和双控开关阀芯的连通通道一和连通通二、连通双控开关阀芯和第一出水腔的连通通道三均开设在开关阀芯座上，使得壳体内只有一个轴向设置的第二国税通道，简化了壳体内部结构，壳体可以通过使用铜等金属浇筑而成，强度更高，寿命更长，耐腐蚀、抗老化性更好。
连通通道一、连通通道二和连通通道三单独设置在阀芯座上，连通通道一端与开关阀芯座外侧端面连通，另一端只要与第一过水腔、第一出水腔或者混合出水腔连通即可，功能简单，相应的结构也能得到简化，从而方便制造。开关阀芯座可以通过注塑制成，由于内部的连通通道较为简单，所以可以从开关阀芯座一端进行抽芯，方便加工。同时该开关阀芯座也可以使用浇铸方式进行加工，或者使用金属棒料通过钻孔加工对连通通道进行加工。
恒温阀芯可以使用由石蜡作为感温材料的温包作为感温元件，也可以使用由记忆合金制成的弹簧作为感温原件。当使用温包作为感温元件时，恒温阀芯的第一进水区域进冷水，第二进水区进热水，混合水从恒温阀芯下端流出。当使用有记忆合金制成的弹簧作为感温原件时，恒温阀芯的第一进水区进热水，第二进水区进冷水。
优选的，第二进水口设置在双控开关阀芯侧面，第二进水通道与开关阀芯腔连通；或者第二进水口设置在双控开关阀芯底面，壳体内设置有第二进水腔，第二进水腔与第二进水通道连通，开关阀芯座内设置有连通通道四，连通通道四连通进水腔二和第二进水口。
通过上述技术方案，当开关阀芯腔直接与第二进水通道连通时，可以使用一个进水口设置在侧面的双控开关阀芯，从而使得一支水路能够直接从双控开关阀芯侧面进入到双控开关阀芯内，从而无需再壳体内设置第二进水腔，同时也能减少开关阀芯座内的连通通道的数量。
同时也可以使用两个进水口都设置在底面的双控开关阀芯，如专利号为201710190716.6的双路同步开关节流阀芯，两路进水都从阀芯底面进水，而后经过双控开关阀芯内的阀片从底面出水，而后通过连通通道流向相应的腔。
优选的，壳体上还设置有第二出水通道，壳体内设置有与第二出水通道连通的第二出水腔，开关阀芯座上开设有连通通道五，双控开关阀芯底面设置有混合水第二出水口，连通通道连接第二出水腔和混合水第二出水口。
通过上述技术方案，第二出水通道、第二出水腔及连通通道五的设置可以实现双路出水，此时双控开关阀芯可以使用带有分水功能的双控开关阀芯，如我公司生产的专利号为201510538006.9中实施例所公开的双路出水陶瓷阀芯。相应的，当两个进水口都设置在双控开关阀芯底面时，还能使用我公司生产的专利号为201711035947.6中实施例所公开的一种可承高压的分水阀芯，从而提高双控开关阀芯的承压能力。
优选的，第一出水腔和第二出水腔处在第二过水腔及混合出水腔之间，第二过水通道处在第一出水腔和第二出水腔外侧。
通过上述技术方案，第二过水通道这样设置，可以避免第二过水通道和第一出水腔、第二出水腔及混合出水腔之间发生干涉，同时也不会对阀芯座的安装产生影响。
优选的，开关阀芯座外侧设置有多个密封凸环，密封凸环与进水腔二、第二过水腔、第一出水腔、第二出水腔混合出水腔两侧的壳体密封配合。
通过上述技术方案，可以避免相邻的两个腔之间在开关阀芯座外侧发生泄漏。密封凸环上可以开设密封圈槽，并在密封圈槽内安装密封圈从而进一步提高密封效果。
优选的，相邻的两个密封凸环之间设置有过流凹槽，连通通道一、连通通道三分别连通一个过流凹槽。
通过上述技术方案，过流凹槽的设置，可以使得连通通道与各腔连通的一端开口更大。阀芯座通过浇铸方式进行加工时，过流凹槽可以在砂模上设置凸块用于形成过流凹槽。当阀芯座通过使用棒料加工制成时，过流凹槽可以通过在阀芯座侧面钻孔或者进行铣削加工形成。
优选的，连通通道一、连通通道二、连通通道三为直孔并沿开关阀芯座轴向设置。
通过上述技术方案，连通通道均为直孔，径向截面大小一致，并且沿着开关阀芯座轴线方向设置可以方便连通通道的加工。
优选的，第一出水通道和/或第二出水通道上安装有分水阀，分水阀外侧套设有摇摆嘴，摇摆嘴与分水阀把手周向固定，摇摆嘴侧面设置有第一分水出口，摇摆嘴下端设置有第二分水出口。
通过上述技术方案，摇摆嘴的设置可以在第一出水通道或者第二出水通道上形成另外的一个出水口，从而实现三路出水或者四路出水。通过分水阀芯可以较为方便地实现两个分水口之间的出水切换。分水阀芯为行业能通用配件，可以直接购买获得。
优选的，壳体内设置有对开关阀芯座进行轴向定位的定位部。
通过上述技术方案，定位件及定位部的设置可以阀芯座的径向位置进行确定，从而保证开关阀芯与开关阀芯座能够抵紧，同时密封凸环的能刚好处于相邻的两个腔之间。
优选的，第二过水通道靠近壳体背面一侧。
通过上述技术方案，第二过水通道设置在该处，水龙头安装在墙上时，朝向墙面一侧，即使第二过水通道内流的是热水，也不容易发生烫伤事故。
与现有技术相比，本发明的有益效果为：通过在壳体内设置开关阀芯座，将连通通道设置在开关阀芯内从而简化壳体的整体结构，方便壳体的浇铸加工。同时在壳体内设置多个分隔的腔使得开关阀芯座内只需设置连通双控开关阀芯和不同腔的连通通道即可，开关阀芯座整体结构较为简单，加工较为方便，可以通过多种方式进行加工。

具体实施方式
以下结合附图对本发明作进一步详细说明。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
实施例一，一种防串水恒温水龙头
如图1所示，一种防串水恒温水龙头,包括壳体1,壳体1两端分别安装有恒温阀芯2和双控开关阀芯3,恒温阀芯2和双控开关阀芯3之间的壳体1内部安装有开关阀芯座7。恒温阀芯2通过侧面自带的螺纹固定在壳体1一端，双控开关阀芯3外侧设置有压盖38，压盖38将双控开关阀芯3及开关阀芯座7压紧在壳体1内。双控开关阀芯3及恒温阀芯2把手上安装有手轮39，用于对双控开关阀芯3的连通状态进行控制、对恒温阀芯2的出水温度进行设定。
如图2～3所示，壳体1后端设置有第一进水通道4和第二进水通道5，第一进水通道4和第二进水通道5分别位于壳体1的右侧和左侧。壳体1内左端为开关阀芯腔18，壳体1右端设置有进水腔一8、进水腔二9和混合出水腔10，恒温阀芯2插设在进水腔一8、进水腔二9及混合出水腔10内。进水腔一8连通第一进水通道4和恒温阀芯2的一个进水口，恒温阀芯2的另一个进水口处在进水腔二9内，冷水和热水在恒温阀芯2内混合后从恒温阀芯2下端进入到混合出水腔10内。开关阀芯腔18内侧设置有第二进水腔26，第二进水腔26和第二进水通道5连通，第二进水腔26右侧为第二过水腔16。第二过水腔16和混合出水腔10之间为第一出水腔27和第二出水腔23，第一出水腔27与壳体1下表面上的第一出水通道6连通，第二出水腔23和壳体1上表面上的第二出水通道22连通。第二过水腔16和进水腔二9通过第二过水通道17连通， 第二过水通道17处在第一出水腔27和第二出水腔23外侧，并靠近壳体1背面，安装时第二过水通道17处在壳体1朝向向墙面的一侧，从而避免第二过水通道17内流动的水为热水时使用者与第二过水通道17外侧的壳体1之间发生接触，发生烫伤。
双控开关阀芯3包括设置在底面上的第二进水口11、第二出水口12、混合水进口13、混合水第一出口14及混合水第二出口15。开关阀芯座7处于双控开关阀芯3内侧，双控开关阀芯3底面与开关阀芯座7朝向双控开关阀芯3的端面抵触密封。开关阀芯座7呈柱状，插设在壳体1内开关阀芯腔18到混合出水腔10之间。开关阀芯座7内开设有沿开关阀芯座7轴线设置并且为直孔的连通通道一19、连通通道二20、连通通道三21、连通通道四25及连通通道五24。连通通道一19、连通通道二20、连通通道三21、连通通道四25及连通通道五24的径向截面形状保持不变。其中连通通道二20大致处于开关阀芯座7中心并贯穿开关阀芯座7两端面，连通通道二20连通混合出水腔10和双控开关阀芯3的混合水进口13。连通通道一19、连通通道三21、连通通道四25及连通通道五24环绕在连通通道二20外侧。开关阀芯座7侧面设置有多个密封凸环28，开关阀芯座7安装后,密封凸环28与开关阀芯座7外侧相邻的两个腔之间的壳体1内表面抵触密封。密封凸环28上还可以开设密封圈槽36，并在密封圈槽36内安装密封圈，从而提高密封效果。相邻的两个密封凸环28之间的开关阀芯座7上还开设有过流凹槽29，连通通道一19、连通通道三21、连通通道四25及连通通道五24一端处在开关阀芯座7左端端面，另一端分别与一个过流凹槽29连通。其中连通通道一19一端与双控开关阀芯3底面的第二出水口12连通，另一端与处在第二过水腔16内的过流凹槽29连通。连通通道三21一端与双控开关阀芯3腔底面的第一出水口连通，另一端与第一出水腔27内的过流凹槽29连通。连通通道四25一端与双控开关阀芯3底面的第二进水口11连通，另一端与处在第二进水腔26内的过流凹槽29连通。连通通道五24一端与双控开关阀芯3底面的混合水第二出水口12连接，另一端与处在第二出水腔23内的过流凹槽29连通。过流通道和过流凹槽29的设置使得开关阀芯座7能够连通多个不同的腔和开关阀芯座7底面的多个进、出水口，实现该水龙头的整体功能。同时开关阀芯座7和壳体1分体设置，大大方便了壳体1和开关阀芯座7的加工。壳体1内部结构简单，可以通过浇铸的方式进行加工，从而提高壳体1的整体强度及抗腐蚀、耐用程度。开关阀芯座7可以通过浇铸、注塑、或者对棒料进行钻、铣加工获得，加工方式多样，可以根据实际需要及加工设备灵活设置。当使用棒料进行加工时，密封凸环28可以通过车削进行加工，各个连通通道可以通过钻孔进行加工。过流凹槽29可以通过钻孔或者铣削进行加工。
第一出水口上还安装有分水阀芯30，分水阀芯30为行业内通用的配件，可以通过购买获得，专利号为201520658168.1的专利说公开的产品中也有使用(即其中的摇摆嘴31快开阀芯17)。如图1所示，分水阀芯30上端通过螺纹固定在第一出水通道6上，分水阀芯30侧面开设有一个出水口45，分水阀芯30下端的把手端面上开设有第二个出水口45，转动把手时水流可以在两个出水口之间进行切换。摇摆嘴31套设在分水阀芯30外侧，并与分水阀芯30的把手周向固定，当摇摆嘴31转动时同时带动分水阀芯30的把手转动，从而改变分水阀芯30的出水状态。第二出水口12上设置有固定接头37，固定接头37与分水阀芯30把手下端螺纹连接，从而将摇摆嘴31固定在分水阀芯30外侧。当第一分水出口32处于恒温阀芯2一侧时，第二分水出口33与第一出水通道6连通，当摇摆嘴31转动到壳体1正面时，第一分水出口32与第一出水通道6连通。
双控开关阀芯3可以使用本公司申请的专利号为201510538006.9及201711035947.6中所公开的开关阀芯。这两篇专利中已经较为详细地对阀芯内部结构及工作过程进行阐述，在此不再赘述。恒温阀芯采用侧面进水，底面出水的恒温阀芯，该恒温阀芯为行业内通用部件，可以直接购买获得，故其具体结构不再赘述。
实施例二，
如图14所示，实施例二与实施例一的区别在于实施例二中的双控开关阀芯3的第二进水口11设置在阀芯侧面，第二出水口12、混合水进口13、混合水第一出口14及混合水第二出水口12设置在阀芯底面，这样可以使得开关阀芯座7和壳体1的结构得到简化，壳体1上无需设置第二进水腔26，使第二进水口11直接与开关阀芯腔18连通即可，同时无需再开关阀芯座7上开设连通通道五24，进而方便壳体1及开关阀芯座7的生产，降低加工成本。如图15～17所示，此时该双控开关阀芯3可以在专利号为201510538006.9的专利所公开的阀芯基础上进行改进获得，在专利号为201510538006.9所公开的阀芯外壳40侧面开设一个与内腔连通的进水口45，同时在动阀片41下表面上开设两个与进水口45连通的入水口43，在定阀片42上开设有一个贯穿定阀片42的出水孔44，装配后，出水孔44处于两个入水口43之间。第二进水通道5内的水从双开关阀芯外壳40侧面进入到动阀片41上的两个入水口43，转动动阀片41时，当其中一个入水口43与出水孔44重合则实现出水。
此外该双控开关阀芯还可以使用专利号为201710887198.3的中国专利中所公开的具有分水功能的开关阀芯。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
