所述滤网70装设在环座33内,且,滤网70外环位于装接槽331外侧,以使得流经滤网70的水流能进入装接槽331和环座33内。
所述开闭机构60包括一弹性的密封圈63,所述密封圈63装设在装接槽331内,其中:当供水源流经滤网70后的水流水压大于预设压值时密封圈63受水压作用变形并向下活动或向下变形,离开分流孔31入口,开闭水路50被打开,分流孔31入口打开,所述水流能流入第二部分的分流孔31,也即是第一部分、第二部分的分流孔31均过水;当供水源流经滤网70后的水流水压小于预设压值时密封圈63复位并位于分流孔31入口处,开闭水路50被密封,密封分流孔31入口,第二部分的分流孔31不过水,只有第一部分的分流孔31过水。本实施例之中,密封机构采用弹性密封圈,但并不以此为限,根据需要,本领域技术人员无需创造性劳动也可涉及密封环加弹簧配合实现替代。
最好,所述环座33上装接有防脱座,所述防脱座包括一外圈332和若干环形陈列固设在外圈332内周面的径段333,所述径段333末端下设卡缘334,所述外圈332装接在环座33,且,所述卡缘334下端面接触在环座33之位于锥面3311之内的端面上,以防止密封圈脱离。
以上所述,仅为本发明较佳实施例而已,故不能依此限定本发明实施的范围,即依本发明专利范围及说明书内容所作的等效变化与修饰,皆应仍属本发明涵盖的范围内。
