起泡器还和节水装置一起使用，使其具有节水功能。但是，这种起泡器通常只具有一种工作状态。即节水状态，不能实现大流量，因此，限制了其使用范围。
发明内容
本发明的目的在于提供一种可切换水量的节水起泡器，以解决现有技术中存在的上述问题。

在初始位置，切换轴的密封部件堵塞起泡装置的第一水流通道，此时仅第二水流通道出水；
在第二位置，切换轴的密封部件脱离起泡装置，第二水流通道打开并在水压的作用下保持打开状态，此时第一水流通道和第二水流通道都出水。
在本发明的较佳实施例中，所述切换轴具有一大端，该大端套设所述密封部件。
在本发明的较佳实施例中，分水体的中央设有一中空凸起，沿着凸起的边缘设有多个分水口；凸起的内部设有向下开口的容纳腔，切换轴的密封部件进入容纳腔时将该容纳腔密封。
在本发明的较佳实施例中，所述的起泡装置包括一进水体以及一整流器，进水体设置于进水端，整流器设置在进水体下方。
在本发明的较佳实施例中，进水体包括圆周壁，圆周壁内部底部设有隔板，其中隔板上设有多个通孔；隔板的中央设有第一轴孔，该第一轴孔朝向分水体的一侧设有直径扩大的阶梯孔。
在本发明的较佳实施例中，整流器为盘状，上面设有多道同心圆环，圆环之间设有多条径向的短柱，相邻短柱之间形成通水孔；整流器中央设有能容纳切换轴的第二轴孔。
在本发明的较佳实施例中，切换轴为圆柱形，其上端设有两道环绕圆周壁的凸缘，这两道凸缘之间形成一道环形凹槽，所述的密封部件为安装于该环形凹槽的密封圈。
在本发明的较佳实施例中，起泡装置还包括一平面滤网，其安装于起泡装置的出水端，该平面滤网的中央设有能容纳切换轴的第三轴孔。
在本发明的较佳实施例中，还包括切换轴复位装置，所述的复位装置包括一弹簧，弹簧的一端顶靠于切换轴上，另一端顶靠于分水体底部上。
在本发明的较佳实施例中，切换轴的端部轴心处设有弹簧定位腔，分水体底部的容纳腔设置一可伸入弹簧定位腔的定位柱上；弹簧一端位于切换轴的弹簧定位腔内，另一端抵靠在分水体的定位柱上。
在本发明的较佳实施例中，分水体凸起的下边缘形成裙边，分水口设置在裙边与凸起连接处，相邻分水口间均设有加强筋；凸起的顶部为圆弧段。
在本发明的较佳实施例中，所述的起泡装置包括进水体、整流器；进水体包括圆周壁，圆周壁内部底部设有隔板，其中隔板上设有多个通孔；进水体圆周壁内其隔板上方依次设有定位台阶、安装槽。

由上述描述可知，本发明提供了一种可切换水量的节水起泡器，其具有两种使用状态。平时为节水状态，此时切换轴起泡装置的第一水流通道被切换轴堵住，只有第二水流通道能出水。这种状态适合低流量需求。
在需要大流量时，将切换轴往上推，第一水流通道被打开，第一水流通道和第二水流通道都能出水，此时的出水量大，可以满足盛水等大流量需求。本发明还设有复位装置。在大流量的状态，由于水压的向上作用，切换轴克服了复位装置的作用力，被顶靠在分水体上而不下落。当关闭水龙头时，在复位装置的作用力下，切换轴被向下推，回到初始状态，此时又恢复为一路出水，具有强制节水的优点。
本发明结构构件少，体积小，并可实现两种出水状态的自由切换。

具体实施方式
本发明的具体实施例，参照图1至图3，一种可切换水量的节水起泡器，由滤网1、分水体2、进水体4、切换轴6、整流器7和壳体9等组成。
该滤网1为半球形，上设有多个用于分散水流的通孔11，滤网1下边缘为装配圈12 。
分水体2的中央设有一圆柱形凸起21，沿着凸起21的下边缘设有多个分水口22。凸起21的内部设有向下开口的容纳腔23，容纳腔内轴心处设有向下的定位柱24。圆柱形凸起21的下边缘形成裙边25，分水口22设置在裙边25与凸起21连接处，相邻分水口22间均设有加强筋26；圆柱形凸起21的顶部为圆弧段27 （见图1、2、3）。
参见图4，进水体4包括圆周壁41，圆周壁41内部底部设有隔板42，其中隔板42上设有多个通孔43。隔板42的中央设有第一轴孔44，该轴孔44朝向分水体2的一侧设有直径扩大的阶梯孔45。圆周壁41内其隔板42上方依次设有定位台阶46、安装槽47。
参见图5，切换轴6为圆柱形，其中部小，两头大，中部65直径小于隔板42的轴孔44的直径，两者之间形成水流通道。而其上端设有两道环绕圆周壁的凸缘61和62，凸缘61的直径大于轴孔44的直径，小于阶梯孔45的直径，这样凸缘61可以进入阶梯孔45，覆盖封闭切换轴中部65与轴孔44之间的水流通道。这两道凸缘之间形成一道环形凹槽63，安装时，密封圈3即卡接于该环形凹槽63中，并和阶梯孔45的内壁抵触，充分封闭前述的水流通道。该切换轴6还设有向上开口的插孔64，弹簧5定位于该插孔64内。
整流器7为盘状，上面设有多道同心圆环71，圆环之间设有多条径向的短柱72，相邻短柱之间形成通水孔。整流器中央设有能容纳切换轴6的第二轴孔73。
平面滤网8的中央设有能容纳切换轴6的第三轴孔83。
壳体9的周壁间隔设有若干个条形吸气孔91，壳体内部的底板中央设有能容纳切换轴6的第四轴孔93。轴孔93周围的底板上设有出水口92。
本发明的平面滤网8、整流器7、进水体4依次安装在壳体9内；切换轴6套装在进水体4内，其下部66依次穿过进水体第一轴孔44、整流器第二轴孔73、平面滤网第三轴孔83及壳体第四轴孔93；分水体2安装在进水体4内定位台阶46上，滤网1安装在分水体2上方，其装配圈12嵌接在进水体4内安装槽47。滤网1内壁与分水体2外周面形成一进水腔体；分水体裙边25的下表面与进水体隔板42上表面间形成出水腔体。由于圆柱形凸起21的顶部为圆弧段27使得进水通畅，斜向设置的加强筋26保证了分水体2的强度及水流通畅。
本发明的使用如下，在通常状态下，为节水状态，此时切换轴6上的凸缘61进入阶梯孔45，覆盖封闭切换轴中部65与轴孔44之间的水流通道，密封圈3位于进水体4的阶梯孔45内壁之间，进一步密封，使水流不能从第一轴孔44通过。从滤网1进入起泡器的水流经过分水体2的分水口22，向下流经进水体4的通孔43，再经过整流器7整流以及和空气混合，产生气泡。之后经过平面滤网8缓冲，最后从壳体9的底部出水口流出。
在需要大流量时，将切换轴6往上推，至密封圈3抵触分水体2的凸起21的内壁。此时除了和节水状态一样的出水路线外，水流还从切换轴6与进水体4的第一轴孔44内壁之间的空腔向下流，经过整流器7的第二轴孔73、滤网8的第三轴孔83以及壳体的第四轴孔93出水。由于增加了一路出水，此时的出水量大，可以满足洗菜等需求。
在大流量的状态，由于水压的向上作用，切换轴6克服了弹簧5的作用力，被顶靠在分水体2的凸起21内壁而不下落。当关闭水龙头时，水压小时，在弹簧5的复位作用力下，切换轴6被向下推，回到初始状态，此时又恢复为一路出水，因此，本发明具有强制节水的优点。
上述仅为本发明的一个具体实施例，但本发明的设计构思并不局限于此，凡利用此构思对本发明进行非实质性的改动，均应属于侵犯本发明保护范围的行为。
工业实用性
本发明一种可切换水量的节水起泡器，在初始位置，切换轴的密封部件堵塞起泡装置的第一水流通道，此时仅第二水流通道出水；在第二位置，切换轴的密封部件脱离起泡装置，第二水流通道打开并在水压的作用下保持打开状态，此时第一水流通道和第二水流通道都出水，本发明可实现两种出水状态的自由切换，具有良好的工业实用性。
