Description

一种换向阀及使用该换向阀的喷雾泵
技术领域
本实用新型涉及一种喷雾泵，尤其是一种用于喷雾泵的换向装置。
背景技术
目前现有技术，一种喷雾泵包括按头、螺牙、锁盖、本体、主柱、副柱、活塞、玻璃球、主弹簧和或副弹簧和吸管，本体的下端设有吸管接口，吸管与吸管接口插接。存在问题是：正常使用时，按头位于上方，按压按头，容器内的液体进入吸管，然后由按头喷出；当液体容器倒置时，接头位于下方，吸管的进液管位于顶部，无液体进入吸管。
实用新型内容
本实用新型的目的是：提供一种换向阀，它具有使喷雾泵直立和倒立均能使用的特点。
本实用新型的另一目的是：提供一种喷雾泵，它具有直立和倒立均匀喷雾的特点。
本实用新型是这样实现的：一种换向阀，它包括换向阀体、吸液管和钢球，
换向阀体包括阀腔、与阀腔相通的插接管、接口和阀腔相通的上端开口的单向阀腔，单向阀腔内设有钢球座，插接管、阀腔和接口的轴线在一条直线上；
吸液管插入接口内，钢球与钢球座配合，钢球保持在单向阀腔内。
所述的一种换向阀，其特殊之处在于：所述单向阀腔的设有沿轴向的进液孔。
所述的一种换向阀，其特殊之处在于：所述单向阀腔的内壁的上端设有至少二个凸起。
所述的一种换向阀，其特殊之处在于：所述凸起呈球形曲面。
一种喷雾泵，包括本体，所述换向阀的插接管与本体下端的吸液接口插接。
本实用新型一种换向阀，直立时，液体经吸液管、阀腔和插接管方向流动；倒立时，液体经单向阀体、阀腔进入接插管；起到换向作用。一种喷雾泵，直立及倒立时，均可以喷雾，使用方便。
附图说明
图1是本实用新型的剖视国。
图2是本实用新型的立体图。
图3是本实用新型的俯视图。
图4是图3的A—A视图。
具体实施方式
下面结合附图对本实用新型作进一步描述。
如图1、图2所示，一种换向阀，它包括换向阀体1、吸液管2和钢球3，
换向阀体1包括阀腔11、与阀腔相通的插接管12、接口13和阀腔相通的上端开口的单向阀腔14，单向阀腔14内设有钢球座141，插接管12、阀腔11和接口13的轴线在一条直线上；
吸液管2插入接口13内，钢球3与钢球座141配合，钢球3保持在单向阀腔14内。
所述单向阀腔14的设有沿轴向的进液孔142。
所述单向阀腔14的内壁的上端设有二个凸起143，二个凸起143在一条直径线上；
所述凸起143呈球形曲面。
如图1所示，一种喷雾泵4，包括本体5、换向阀，换向阀的插接管12与本体5下端的吸液接口51插接。
现有技术喷雾泵4装设换向阀后，容器直立时，吸液管2伸入容器的底部，吸液管2的进液端与地面相对，换向阀的钢球3与钢球座141紧密配合；按压喷雾泵4的按头41，容器内的液体经吸液管2、换向阀的阀腔11、插接管12进入喷雾泵4的本体5，最后由按头41喷出；
容器倒立时，吸液管2的进液端伸入出液面，换向阀的钢球3离开钢球座141，钢球与凸起143配合止位，液体经单向阀腔14进液孔142进入单向阀腔14内，再经钢球座141进入阀腔，从而实现倒立喷雾。
以上所述的仅是本实用新型的优先实施方式。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型原理的情况下，还可以作出若干改进和变型，这也视为本实用新型的保护范围。
