背景技术
现卫浴行业花洒、莲蓬头、组合花洒等结构的水流量控制功能均是通过控制水龙头流量的方式来控制不同的水花模式下的花洒出水流量，此方法不仅浪费时间，而且无法准确、快速地调整得到需要的流量，特别是一些具有多种水花模式，而每种水花模式的水流量不同的花洒中，需要针对该水花模式设计特定的流量才可实现该花洒模式下最为舒适的出水方式。
有鉴于此，本发明人特别研制出一种可准确快速调整出水流量的花洒流量控制结构，本案由此产生。

具体实施方式
实施例一
如图1-3所示，本发明揭示的一种花洒流量控制结构，包括：
进水组件1，其具有接通供水管路的进水通道121；进水组件可以是花洒接头，也可采用球头11和球头固定座12组成的进水结构，球头11下端套接固定在球头固定座12上，球头固定座12开设进水通道121。
面盖封水座2；其密封联接在进水组件1的球体固定座12下端，且具有多个下水孔21，进水通道121可切换至与其中一个下水孔21连通；
一级限流器3，设置在进水通道中；以及
多个二级限流器4，各二级限流器4一一对应的设置在各下水孔21中，一级限流器3的流量大于二级限流器4流量，且各二级限流器4流量不同。
本实施例的一级限流器3的流量为2.5GPM，所述下水孔21与二级限流器4均为两个，其中一个二级限流器4的流量为2.0GPM，另一个二级限流器4的流量为1.75GPM。如图3所示，一级限流器3设有控制水流量的O型圈7，利用O型圈7进行水流量控制是一种常见的水流控制方式；二级限流器4中设有控制水流量的O型圈7或黑豆9，利用黑豆9来控制水流量具有更好的水流稳定性，请参见图9-10，黑豆9的周壁形成6个等间距分布的缺口91，黑豆9还竖向开设多个进水孔92，黑豆9与二级限流器4底面之间流出过水区间，水流通过黑豆9周壁的缺口91和上下贯通的进水孔92进水，水流从过水区间以及进水孔23直接流入下水孔21；由于黑豆2为橡胶件，在水压作用下黑豆9的进水位置发生变形，水压较低时黑豆9进水位置基本不变型，水流可从缺口91到达下水孔21，水压变高后，黑豆9进水位置挤压变小，进水区间封闭，水流只能够从进水孔92进入，从而实现高低水压流量一致。
以及进水孔92流入下水孔21，黑豆9一般采用橡胶材质，，水流速过快时，缺口91。
上述选取的一级限流器3流量和各二级限流器4的流量并非对本发明实施方案的限制，根据不同的水花模式和水流量需求，可旋转各种不同流量的限流器来搭配使用。
如图1-3所示，为便于面盖封水座2的安装以及水花模式的切换，本实施例的流量控制结构还包括旋转支座5，面盖封水座2上端与进水组件1下端均套入旋转支座5中，通过选择支座5将面盖封水座2可相对旋转的方式对接在进水组件1的球头固定座12下端。为保证水流的稳定性，进水通道121下端安装一猫眼垫8，猫眼垫8对接下水孔21，猫眼垫8与猫眼、密封垫的作用相同，在卫浴设备领域属于常用的密封器件，猫眼垫8在本发明花洒中的作用是保证进水通道121的水顺利流入下水孔21中。
参见图2和3，于本实施例，上述的流量控制结构还包括出水面盖6，该出水面盖6以可带动面盖封水座2相对进水组件旋1转的方式连接在面盖封水座2下方。为进一步简化水花模式切换操作，出水面盖6侧面形成旋转手柄61。
进一步，二级限流器4可以旋转采用可拆卸的方式安装在面盖封水座的下水孔中，也可以旋转二级限流器4一体成型于下水孔21中。
实施例二
如图，本实施例与实施例一结构大致相同，不同之处在于：下水孔与二级限流器4均为三个，其中一个二级限流器4的流量为2.0GPM，一个二级限流器4的流量为1.75GPM，另一个二级限流器4的流量为1..5GPM。
以上仅为本发明的具体实施例，并非对本发明的保护范围的限定。凡依本案的设计思路所做的等同变化，均落入本案的保护范围。
