本专利申请要求申请日为2022年6月22日、申请号为202210715512.0、名称为一种按摩喷头的中国专利申请的优先权，以上中国专利申请的公开内容以引用方式全文并入于此。
技术领域
本文涉及卫浴技术领域，尤指一种按摩喷头。

为多个喷水孔供水的供水装置体积庞大，不利于喷水孔的布局，且供水装置仅能提供触感单一的脉冲水流。
发明概述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
为解决上述技术问题，本申请实施例提供了一种按摩喷头，其包括：
壳体，设置有集液腔、从所述集液腔的一端延伸到所述壳体外的出水通道以及多个贯穿所述集液腔的周壁的子通道，多个所述子通道沿所述周壁的周向依次排布；
叶轮，与所述壳体转动连接，设置有遮挡面；
其中，所述叶轮由流经所述子通道的水驱动而发送转动，所述叶轮在转动时所述遮挡面能从多个所述子通道的端部依次经过，所述遮挡面能遮挡正在经过的子通道的端部。
在一个示意性的实施例中，所述壳体包括
端盖，包括筒体、覆盖在所述筒体一端的出水部以及设置在所述出水部的内侧的凸环，所述筒体与所述凸环之间形成环形腔；
盖板，覆盖在所述凸环背离所述出水部的一端；
其中，所述凸环、所述出水部和所述盖板围合出所述集液腔，所述出水通道贯穿所述盖板且与所述凸环同轴，所述子通道均设置在所述凸环上且贯穿所述凸环。
在一个示意性的实施例中，所述凸环背离所述端部的一端设置有多个条槽，所述条槽从所述凸环的内周面延伸到所述凸环的外周面；
所述盖板盖合在所述条槽的开口，所述条槽的内表面与所述盖板覆盖所述开口的表面围合出所述子通道。
在一个示意性的实施例中，所述盖板上还设置有引导柱，所述引导柱的一端连接于所述盖板，另一端伸入所述出水通道；
所述引导柱、所述凸环和所述出水通道均同轴设置。
在一个示意性的实施例中，所述引导柱从所述盖板到所述出水通道的方向上半径逐渐减小。
在一个示意性的实施例中，所述盖板朝向所述凸环的板面上设置有环形的凸起，所述凸起的顶端与所述凸环的顶端相抵。
在一个示意性的实施例中，所述叶片设置在所述集液腔内；
所述叶轮包括：
连接环，外周面与所述集液腔的内壁间隙配合；以及
叶片，连接于所述连接环，包括前端以及与所述前端相对的末端，所述末端设置有受力面；
所述子通道通过将水喷射到所述受力面上来驱动叶轮转动，所述遮挡面为所述叶片的外侧面。
在一个示意性的实施例中，所述受力面设置在所述末端靠外的一侧，所述受力面构造为凹陷的弧面。
在一个示意性的实施例中，至少一部分所述子通道沿所述集液腔的径向 延伸；和/或
至少一部分所述子通道不沿着所述集液腔的径向延伸。
在一个示意性的实施例中，所述前端的宽度小于所述末端的宽度。
在一个示意性的实施例中，所述叶片设置有多个，多个叶片均匀地分布在连接环上。
在一个示意性的实施例中，所述叶片到所述连接环的轴线的距离小于出水通道的半径。
在一个示意性的实施例中，所述盖板还密封所述筒体背离所述出水部的一端；
所述盖板上设置有连通所述环形腔的加速孔；
所述叶轮设置在所述环形腔内，所述叶轮包括套在所述凸环上的连接环、从连接环向外侧伸出的叶片以及连接于所述连接环的挡板；
所述遮挡面为挡板的内侧面；
其中，所述加速孔能向所述环形腔注水，所述加速孔通过将水倾斜地喷射到所述叶片上来驱动叶轮转动。
在一个示意性的实施例中，所述加速孔的延伸方向与连接环的轴线呈夹角。
在使用这种按摩喷头时，多个子通道同时向集液腔内注水，一部分子通道被遮挡面所堵塞而无法向集液腔内注水，水在流经叶轮时带动叶轮转动。在叶轮转动时，叶轮带动水流旋转，该旋转的水流通过出水通道喷出壳体，同时，叶轮的遮挡面在转动时还依次经过多个子通道朝内的端部，该遮挡面会遮挡住其所经过子通道的端部使得该子通道无法继续向集液腔内注水，这样，遮挡面轮流遮挡和离开子通道的端部时水流会间歇性地冲击集液腔，最终从出水通道输出的水流在平行于出水通道和垂直于出水通道的方向上均具有脉冲感，从而形成按压加揉捏的双重按摩感受。
这种按摩喷头体积小，结构简单，在布局到浴缸上时更加灵活。

详述
实施例一
如图1-3所示，图1-3显示了实施例一中的按摩喷头1。该按摩喷头1包括壳体2和叶轮3。叶轮3设置在壳体2内。
壳体2包括外筒21、端盖22和盖板23。外筒21构造为管状结构。端盖22覆盖在外筒21的一端，且连接于外筒21。外筒21背离端盖22的一端设置成外接供水管路，供水管路向外筒21内注水。
端盖22包括筒体221、出水部222和凸环223。筒体221构造为圆筒形结构。出水部222覆盖在筒体221的一端。筒体221的外周面上设置有外螺纹，外筒21上设置有与该外螺纹相匹配的内螺纹，筒体221拧入到外筒21内以与外筒21之间螺纹连接。
出水部222构造为圆环状。出水部222封堵该筒体221的端部。出水部222上设置有出水通道224，该出水通道224贯穿出水部222。出水通道224为直通道，其横截面可以是圆形。出水通道224与筒体221同轴设置。
如图2所示，凸环223构造为圆环状。凸环223设置在出水部222朝向筒体221内的板面上。凸环223围合在出水通道224的周围。凸环223与出水通道224同轴设置。凸环223的内腔与出水通道224相接通。凸环223背离出水部222的一端上设置有多个条槽226。条槽226由凸环223的端面向内凹陷形成。条槽226从凸环223的内周面延伸到凸环223的外周面。多个条槽226沿凸环223的周向依次排布。凸环223的外径小于筒体221的内径，凸环223与筒体221之间形成环形腔225。
盖板23构造为圆盘状。盖板23上覆盖在筒体221背离出水部222的一 端。盖板23还覆盖在环形腔225背离出水部222的一端。盖板23还与凸环223背离出水部222的一端相抵。凸环223、出水部222和盖板23围合出集液腔227。盖板23还覆盖在凸环223的条槽226的开口上，每个条槽226的内表面与盖板23朝向条槽226的表面围合出一个子通道220。子通道220的两端将集液腔227与环形腔225相接通。子通道220可以是直通道。盖板23上设置有加速孔231。加速孔231设置在盖板23的边缘。加速孔231可以设置多个，多个加速孔231在盖板23的周向上均匀分布。加速孔231与环形腔225相连通。
如图5所示，叶轮3设置在集液腔227内。叶轮3包括连接环31和叶片32。连接环31构造为圆环。连接环31与凸环223同轴设置，连接环31的外周面与凸环223的内周面间隙配合，即连接环31的外周面与集液腔227的内壁间隙配合。叶轮3能在集液腔227内绕自身轴线转动。连接环31与出水部222相抵，凸环223上的子通道220均位于连接环31背离出水部222的一侧，连接环31不阻挡子通道220。
如图2所示，叶片32构造为大致的楔形结构。叶片32连接于连接环31。叶片32包括前端321以及与前端321相对的末端322。叶片32的前端321朝向叶轮3的旋转方向，叶片32的末端322的朝向与叶轮3的旋转方向相反。叶片32的末端322上设置有受力面323，受力面323斜向外侧。如图8所示，子通道220向集液腔227注水时能冲到该叶片32的受力面323上，使得叶片32受到一个向前的推力，从而驱动叶轮3转动。
在叶轮3的轴线上，叶片32的厚度大于连接环31的厚度。叶片32从连接环31向子通道220一侧伸出，叶片32能遮挡子通道220朝内的一端。叶片32朝外的侧面为遮挡面320，即叶片32靠近凸环223的内周面的侧面为遮挡面320。该遮挡面320构造为与凸环223同轴的圆弧面，叶片32通过遮挡面320来遮挡子通道220朝内的一端。
如图6、8所示，在供水管路向外筒21内注水后，外筒21内的水通过盖板23上的加速孔231进入到环形腔225中，在水流从外筒21流入到加速孔231的过程中由于流道的截面积突然减小而使得水流的流速增大，进而使得进入到环形腔225中的水流速度较大。环形腔225中的水通过多个子通道220 注入到集液腔227内，至少一部分子通道220能将水喷射到叶片32的受力面323上来驱动叶轮3转动，同时，还有一部分子通道220被叶片32的遮挡面320所堵塞而无法向集液腔227内注水。在叶轮3转动时，叶轮3带动集液腔227内的水旋转，该旋转的水流通过出水通道224喷出壳体2，同时，叶轮3的遮挡面320在转动时还依次经过多个子通道220朝内的端部，该遮挡面320会遮挡住其所经过子通道220的端部使得该子通道220无法继续向集液腔227内注水，这样，遮挡面320轮流遮挡和离开子通道220的端部时水流会间歇性地冲击集液腔227，最终从出水通道224输出的水流在平行于出水通道224和垂直于出水通道224的方向上均具有脉冲感，从而形成按压加揉捏的双重按摩感受。
在一个示意性的实施例中，盖板23上还设置有引导柱232。引导柱232一端连接于盖板23的中部，且位于盖板23靠近出水通道224的一侧。引导柱232的另一端伸入到出水通道224内。引导柱232伸入到出水通道224的部分的直径小于出水通道224的内径。引导柱232与出水通道224之间形成环形间隙。
多个子通道220分别注入到集液腔227中的多束水流能在引导柱232的引导下向出水通道224方向运动，同时由于叶轮3驱动水流旋转，这些水流还能绕着引导柱232旋转流到出水通道224内。
在一个示意性的实施例中，引导柱232连接于盖板23的一端的半径大于引导柱232伸入到出水通道224内的一端的半径。引导柱232从盖板23到出水通道224的方向上，其半径逐渐减小。
这样，引导柱232的外周面与出水通道224所喷出的水流之间为钝角，水流撞击到引导柱232上时所损失的速度小。
在一个示意性的实施例中，盖板23上还设置有凸起233，该凸起233为环形。该凸起233设置在盖板23朝向凸环223的板面上。该凸起233背向盖板23的顶端与凸环223背向出水部222的顶端相抵。由于凸起233与凸环223相抵，能加强盖板23与凸环223之间的密封。
在一个示意性的实施例中，如图2、8所示，叶片32上的受力面323设置在叶片32的末端322靠外的一侧。该受力面323构造为凹陷的弧面。
一部分子通道220沿凸环223的径向延伸时，这部分子通道220将水喷射到弧面状的受力面323上可以使得叶片32受到一个向前的分力，从而推动叶片32转动。
另一部分子通道220不沿着凸环223的径向延伸，这部分子通道220也能将水喷射到弧面状的受力面323上，可以使得叶片32受到一个向前的分力，且该分力相较于径向延伸的子通道220喷水所施加的向前的分力更大，受到该推力后叶片32能旋转更快。
尤其是，这种凹陷的弧面结构的受力面323在受到水流冲击时能更大效率的利用水流的冲击力，将冲击力尽可能多的转化为向前的分力，叶轮3能旋转得更快。
在一个示意性的实施例中，叶片32的前端321的宽度小于叶片32的末端322的宽度。这样，叶片32在转动时受到水的阻力更小，叶轮3能转动得更快。
在一个示意性的实施例中，叶片32到连接环31的轴线的距离小于出水通道224的半径。
这样，在使用该按摩喷头1时，用户可以从出水通道224看到叶片32转动，使得用户能更加直观察看该按摩喷头1是否工作，提升了体验。
在一个示意性的实施例中，如图10、11所示，叶片32设置有多个，例如2个。多个叶片32均匀地分布在连接环31上。每块叶片32可以同时截断多个子通道220。
这样，在叶轮3受到水流的冲击时，叶轮3受力更加均匀，同时叶轮3的转动也更加平衡。
在一些实施例中，如图12、13所示，叶片32a也可以仅设置一个。
叶片32a的数量可以按需求灵活设置。
在一些实施例中，如图14、15所示，叶片32b可以设置多个，每块叶片32b在同一时间仅能截断一个子通道220。
每块叶片32b所能截断的子通道220的数量可以按需求灵活设置。
实施例二
如图16-21所示，图16-21显示了实施例二中的按摩喷头1d。该按摩喷头1d包括壳体2d和叶轮3d。叶轮3d设置在壳体2d内。
如图18、19所示，壳体2d包括外筒21d、端盖22d和盖板23d。外筒21d构造为管状结构。端盖22d覆盖在外筒21d的一端，且连接于外筒21d。外筒21d背离端盖22d的一端设置成外接供水管路，供水管路向外筒21d内注水。
如图17、18所示，端盖22d包括筒体221d、出水部222d和凸环223d。筒体221d构造为圆筒形结构。出水部222d覆盖在筒体221d的一端。筒体221d的外周面上设置有外螺纹，外筒21d上设置有与该外螺纹相匹配的内螺纹，筒体221d拧入到外筒21d内以与外筒21d之间螺纹连接。
如图17所示，出水部222d构造为圆环状。出水部222d封堵该筒体221d的端部。出水部222d上设置有出水通道224d，该出水通道224d贯穿出水部222d。出水通道224d为直通道，其横截面可以是圆形。出水通道224d与筒体221d同轴设置。
凸环223d构造为圆环状。凸环223d设置在出水部222d朝向筒体221d内的板面上。凸环223d围合在出水通道224d的周围。凸环223d与出水通道224d同轴设置。凸环223d的内腔与出水通道224d相接通。凸环223d背离出水部222d的一端上设置有多个条槽226d。条槽226d由凸环223d的端面向内凹陷形成。条槽226d从凸环223d的内周面延伸到凸环223d的外周面。多个条槽226d沿凸环223d的周向依次排布。凸环223d的外径小于筒体221d的内径，凸环223d与筒体221d之间形成环形腔225d。
如图17、19、22所示，盖板23d构造为圆盘状。盖板23d上覆盖在筒体221d背离出水部222d的一端。盖板23d覆盖在环形腔225d背离出水部222d的一端。盖板23d还与凸环223d背离出水部222d的一端相抵。凸环223d、出水部222d和盖板23d围合出集液腔227d。盖板23d还覆盖在凸环223d的条槽226d的开口上，每个条槽226d的内表面与盖板23d朝向条槽226d的表面围合出一个子通道220d。子通道220d的两端将集液腔227d与环形腔225d相接通。子通道220d可以是直通道。盖板23d上设置有加速孔231d。加速 孔231d设置在盖板23d的边缘。加速孔231d可以设置多个，多个加速孔231d在盖板23d的周向上均匀分布。加速孔231d与环形腔225d相连通。
叶轮3d设置在环形腔225d内。叶轮3d包括连接环31d、叶片32d和挡板33d。连接环31d构造为圆环。连接环31d套在凸环223d上。连接环31d的内周面与凸环223d的外周面之间形成间隙配合。连接环31能绕着凸环223d转动。
叶片32d设置有多块，多块叶片32d均从连接环31d向外伸出。叶片32d可以是渐开线形、摆线形或直条形的叶片32d。盖板23d上的加速孔231d构造为斜孔，加速孔231d的延伸方向与连接环31d的轴线呈夹角。加速孔231d相环形腔225d注水时，水流斜射到叶片32d上，从而推动叶轮3d旋转。
挡板33d连接于连接环31d。挡板33d构造为弧形板。挡板33d的内表面为遮挡面331d，为圆弧面。该遮挡面331d朝向凸环223d，且与凸环223d的外周面间隙配合。遮挡面331d能遮挡一部分子通道220d朝外的端部。
在供水管路向外筒21d内注水后，外筒21d内的水通过盖板23d上的加速孔231d进入到环形腔225d中，加速孔231d能为水流加速，使得进入到环形腔225d中的水流速度较大。水流喷射到叶片32d上带动叶轮3d转动。在叶轮3d转动时，叶轮3d带动环形腔225d内的水旋转，该旋转的水流通过子通道220d注入到集液腔227d内，再通过出水通道224d喷出壳体2d。
如图18、21所示，环形腔225d中的水通过多个子通道220d注入到集液腔227d内，至少一部分子通道220d能将水喷射到叶片32d的受力面323d上来驱动叶轮3d转动，同时，还有一部分子通道220d被叶片32d的遮挡面331d所堵塞而无法向集液腔227d内注水。叶轮3d的遮挡面331d在转动时还依次经过多个子通道220d朝外的端部，该遮挡面331dd会遮挡住其所经过子通道220d的端部使得该子通道220d无法继续向集液腔227d内注水，这样，遮挡面331d通过遮挡和打开子通道220d的端部使水流间歇性地冲击集液腔227d，最终从出水通道224d输出的水流在平行于出水通道224d和垂直于出水通道224d的方向上均具有脉冲感，从而形成按压加揉捏的双重按摩感受。
在一个示意性的实施例中，如图19、21所示，盖板23d上还设置有引导柱232d。引导柱232d一端连接于盖板23d的中部，且位于盖板23d靠近出 水通道224d的一侧。引导柱232d的另一端伸入到出水通道224d内。引导柱232d伸入到出水通道224d的部分的直径小于出水通道224d的内径。引导柱232d与出水通道224d之间形成环形间隙。
多个子通道220d分别注入到集液腔227d中的多束水流能在引导柱232d的引导下向出水通道224d方向运动，同时由于叶轮3d驱动水流旋转，这些水流还能绕着引导柱232d旋转流到出水通道224d内。
