一种脚踏开关及带该脚踏开关的调温出水龙头
本技术涉及于卫浴设备
,尤其涉及一种脚踏开关及带该脚踏开关的调温出水龙头。
技术介绍
水龙头是控制水管出入水和水流量的装置,广泛应用于家庭和各种公共场合,现有技术中的水龙头产品主要包括手动式、感应式、脚踏式和手术室专用式,其中手动式水龙头使用时手部必须接触把手,不仅容易发生交叉感染,在关闭水龙头时对洗净的手会造成二次污染,而且在使用过程中水龙头处于开启状态,甚至用过之后忘记关闭,容易造成水的浪费;感应式水龙头存在感应延迟和水量控制难的问题,且使用期间极易出现故障造成跑水,维修工作量大,耗能多;手术室专用式水龙头由于其价格高,难以推广;而传统脚踏式水龙头安装和维修困难、泄水量大且故障率高;此外,上述感应式、手术室专用式和传统脚踏式水龙头都为单路无调温功能,给生活用水带来很大麻烦。因此,需要技术上的进步,结构上的改进,使脚踏式水龙头的结构设计更合理,使用寿命更长。
技术实现思路
因此,针对上述的问题,本技术提出一种脚踏开关,解决现有机械式水阀要用手接触进行操作而易引起疾病传染,以及感应式水阀结构复杂、存在用电安全隐患、浪费电能的问题,同时还可以提高节水能力。为实现上述目的,本技术采用了以下技术方案:一种脚踏开关,包括阀体和阀芯,所述阀体包括外阀体和内阀体,所述外阀体上方通过外锁紧螺母设有盖板,所述外阀体设有外进水口与外出水口,所述内阀体通过内锁紧螺母固定于外阀体内,所述内阀体设有内进水口和内出水口,所述阀芯设于内阀体内,所述阀芯包括上阀芯和下阀芯,所述上阀芯的顶端穿过盖板位于盖板上方,所述上阀芯顶端设有脚踏板,所述上阀芯 ...
【技术保护点】
1.一种脚踏开关,包括阀体和阀芯,其特征在于:所述阀体包括外阀体和内阀体,所述外阀体上方通过外锁紧螺母设有盖板,所述外阀体设有外进水口与外出水口,所述内阀体通过内锁紧螺母固定于外阀体内,所述内阀体设有内进水口和内出水口,所述阀芯设于内阀体内,所述阀芯包括上阀芯和下阀芯,所述上阀芯的顶端穿过盖板位于盖板上方,所述上阀芯顶端设有脚踏板,所述上阀芯位于脚踏板和盖板之间设有上回位弹簧,所述上阀芯的下端位于内阀体内部且有环形凸台,所述环形凸台外表面设有与内阀体内壁紧密接触的阀芯密封圈,所述下阀芯位于环形凸台下方,所述下阀芯的顶端设有卡置凸起,所述内阀体内部于卡置凸起下方设有卡置台,所述下阀芯于卡置凸起和卡置台之间设有下回位弹簧,所述下阀芯的底端通过内进水口伸入外阀体,所述下阀芯底端沿其周向设有可由下向上将内进水口顶紧的凸台,所述凸台上方设有止水密封圈。
