如图1、图2所示，开闭块16的上端面成型有左连接杆161、进排气块17的上端面成型有右连接杆171；左连接杆161的上端穿过主竖直管11的上侧壁；右连接杆171的上端穿过出气管14的上侧壁；左连接杆161的上端和右连接杆171的上端可拆卸式连接有同步连接块18；左连接杆161的上部套设有左拉簧162；左拉簧162的上端与同步连接块18固定连接、下端与主竖直管11的上端面固定连接；右连接杆171的上部套设有右拉簧172；右拉簧172的上端与同步连接块18固定连接、下端与出气管14的上端面固定连接。
如图1、图2所示，左连接杆161的上端和右连接杆171的上端分别成型有外螺纹；同步连接块18竖直穿过左连接杆161和右连接杆171；同步连接块18的上端面上分别枢接有左调节螺母163和右调节螺母173；左调节螺母163螺接在左连接杆161上；右调节螺母173螺接在和右连接杆171上。
如图1、图2所示，出气管14的内侧壁下端成型有若干限位块141；限位块141用于限制进排气块17的下端位置。
如图1、图2所示，开闭块16的下端自左向右倾斜向上设置。
如图1、图2所示，出水管13的出水端设置有出水过滤套15。
防逆的水龙头的工作原理；
初始状态时如图2所示，开闭块16和进排气块17处于最下端，开闭块16封闭主竖直管11和水平管12的连接部分，主竖直管11内残留的水与外接隔离，不容易滋生细菌；
当水龙头开关打开时，主竖直管11上水，顶开开闭块16，水经过 水平管12和出水管13喷出，同时进排气块17同步向上移动，在进排气块17的上升过程中从上单向阀143进气，当水龙头开关关闭时，主竖直管11停止上水，在拉簧的作用下，开闭块16封闭主竖直管11和水平管12的连接部分，同时进排气块17下降使得出气管14内的气流从下单向阀142出气，此气流使得水平管12和出水管13内残留的水尽量排出，这样达到水平管12和出水管13内无残留水，开闭块16把主竖直管11内的水与外界空气隔绝。
以上内容仅为本发明的较佳实施方式，对于本领域的普通技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本发明的限制。
