Description

水路中的吸气止逆机构 技术领域
本发明涉及一种水路中的吸气止逆机构。
背景技术
现有的水路领域中，经常会使用到吸气机构，例如水路领域中的起泡器。现有的吸气机构都只具有进气之功能，不具有堵水功能或者说吸气止逆功能，因此存在有如下不足：在多功能花洒中，当花洒出水功能向非吸气状态功能切换时（如处于非起泡出水功能时），水路管阻变大，水流产生倒流，水流会通过吸气孔向外漏出，进而造成使用不便、浪费水资源、降低水压等之缺点。
发明内容
本发明提供了水路中的吸气止逆机构，其克服了背景技术中水路领域中的吸气机构所存在的在水路水流倒流作用下水流会通过吸气孔向外漏出的不足。
本发明解决其技术问题的所采用的技术方案是：
水路中的吸气止逆机构，它包括：
一主体，它内具有一水路和至少一进气孔；所述水路具有一进水孔和一接通进水孔的突变腔，所述突变腔的截面面积大于进水孔的截面面积；所述进气孔具有一进气口和一出气口，所述进气口位于主体之外，所述出气口位于突变腔；及
一密封件，它活动装接在主体之内，并适配主体的进气孔；
其中：
水路之水流顺流，则所述突变腔产生负压并作用于密封件以使进气孔导通，以能吸气；
水路之水流倒流，则所述水路水压作用于密封件以使密封件密封进气孔。
一较佳实施例之中：
所述进气孔至少包括有一对应出气口的密封口和一位于密封口和出气口之间的活动腔；
所述密封件活动连接在活动腔之内，它在受负压时远离密封口，在受倒流水路水压作用时抵靠并密封密封口。
一较佳实施例之中：另设一顶抵弹簧装接在主体之内用于顶抵密封件，能够防止密封件脱离活动腔。
一较佳实施例之中：所述密封件的截面面积大于密封口的截面面积。
一较佳实施例之中：所述活动腔包括一适配密封件的滑动槽及至少一由滑动槽内侧面凹设的通槽。
一较佳实施例之中：所述主体包括：
一支座，它内开设有一贯穿的安装孔和第一贯穿孔，所述第一贯穿孔贯穿安装孔之内外；及
一内架，所述水路设在内架上，它开设有第二贯穿孔，所述第二贯穿孔贯穿水路的突变腔的内外；
所述内架装配在支座的安装孔之内，所述第二贯穿孔外端口和第一贯穿孔的内端口对接，其中，所述第一贯穿孔的内端口为上述的密封口，所述第二贯穿孔包括上述的活动腔。
一较佳实施例之中：所述第二贯穿孔的内端口为出气口，所述出气口的截面面积小于密封件的截面面积。
一较佳实施例之中：所述支座为一球头，包括一球头部和一连接部，第一贯穿孔设置在球头部。
一较佳实施例之中：所述主体包括：
一支座，它内开设有一贯穿的安装孔和第一贯穿孔，所述第一贯穿孔贯穿安装孔之内外；及
一内架，所述水路设在内架上，它开设有第二贯穿孔，所述第二贯穿孔贯穿水路的突变腔的内外，所述第二贯穿孔之内设有缩口；
所述内架装配在支座的安装孔之内，所述第二贯穿孔的缩口接通第一贯穿孔，其中，所述第二贯穿孔的缩口为上述的密封口，所述第二贯穿孔包括上述的活动腔。
一较佳实施例之中：所述主体包括：
一支座，所述水路设在支座上，它开设有第三贯穿孔，所述第三贯穿孔贯穿水路的突变腔的内外；及
一气孔盖，它开设有一第四贯穿孔；
所述气孔盖装接在支座的第三贯穿孔的外端口，其中，所述第四贯穿孔为上述的密封口，所述第三贯穿孔包括上述的活动腔。
本技术方案与背景技术相比，它具有如下优点：水路之水流顺流，则所述突变腔产生负压并作用于密封件以使进气孔导通，以能吸气，水路之水流倒流，则所述水路水压作用于密封件以使密封件密封进气孔，以能够实现吸气止逆，因此克服了背景技术所存在的不足，避免了在水流倒流时会通过吸气孔向外漏水的缺点。本发明具有良好的通配性，可广泛用于球头、按钮及塞子等卫浴设备的部件中。
