Description

净水器的密封连接装置
技术领域
本实用新型涉及一种净水器的密封连接装置,具体是一种净水器顶盖与净水器壳体之间的密封连接装置。 
背景技术
现有的净水器,主要由壳体、顶盖、滤芯和进出水口等组成,壳体和顶盖一般采用锣牙紧固或用法兰用锣丝紧固,拆装非常不便而且容易漏水;中国专利公开一种净水器,所述净水器中的壳体和顶盖间的密封连接装置包括壳体与顶盖间设有相互配合的锁牙,壳体与顶盖间设有密封圈,密封圈套设于定位圈上,定位圈与顶盖上环形台阶配合形成凹槽,定位圈与壳体口部配合形成凹槽,密封圈置于所述两个凹槽之中。由于密封圈为实芯圆柱状,弹性变形量小。因此,所述壳体和顶盖间的密封连接装置的不足之处是:(1)确保密封时拆装不方便(配合过紧,非专用工具和非专业人士难以拆装);(2)拆装方便时密封性能低,易漏水。 
发明内容
本实用新型的目的在于克服现有净水器顶盖与净水器壳体之间的密封连接装置的不足之处,提供一种拆装方便、密封性能好的净水器密封连接装置。 
本实用新型,包括设置于壳体上边沿的扩径顶肩部和设置于顶盖下边沿的扩径顶肩部,在壳体上边沿的扩径顶肩部与顶盖下边沿的扩径顶肩部之间,设有“Y”形密封圈,在顶盖的下边沿,其周边上均匀设有4-10个缩径锁牙,在壳体上边沿的翻边部,设有与缩径锁牙对应的缩径部,相邻两个缩径部之间为卡扣部,当转动顶盖后,卡扣部与缩径锁牙相互卡扣配合。 
本实用新型,所述壳体上边沿的翻边部可以是“L”形上翻边,所述“Y”形密封圈设置在“L”形上翻边的内侧,“Y”形密封圈的外周与所述壳体上边沿的翻边部相适应。 
本实用新型,所述壳体上边沿的翻边部也可以是“n”形下翻边,所述“Y”形密封圈设置在顶盖下边沿翻边部的内侧。 
本实用新型,具有如下积极效果:(1)由于壳体与顶盖间设有相互配合的锁牙,拆装时,只需转动顶盖使其与壳体错开一小角度,松开或旋紧锁牙便可,可用双手直接拆装,十分方便;(2)由于“Y”形密封圈 “V”形槽的弹性作用,使壳体与顶盖间相互配合的锁牙在松开或旋紧时轻松省力;(3)由于“Y”形密封圈中设有“V”形槽,当净水器工作时,在自来水水压的作用下,“V”形槽会胀开,使壳体与顶盖间的密封性能更好;(4)具有结构简单,制造成本低等优点。
