Induction type water tap

The invention is an induction tap, including a body, a valve driving component in the body, an induction component inducing by infrared to turn on and off the driving component, and a valve core at the joint of water inlet and outlet, where the turnon and turnoff of the valve core is controlled by the valve driving component; the valve driving component includes a micro electric machine, a precision reduction mechanism linked with the micro electric machine, and a valve core with a ceramic chip and linked with the reduction mechanism; the induction component includes an inductor and a drive controller controlled by a microchip program; the battery power supply device supplies low voltage DC power to the drive controller and the inductor. It adopts an integrative design. Its structure is novel and its property is excellent; the whole structure is more reasonable, its model is smaller and more exquisite and it is more reliable to use. 一种感应式水龙头，包括一水龙头本体(11)，一配设在本体内的阀门驱动部件，一以红外线感应而启闭阀门驱动部件的感应部件，以及位于水龙头本体的进水口与出水口连接处的由阀门驱动部件控制的开、关的阀芯；阀门驱动部件包括一微型电机(3)，一与所述的微型电机(3)相连接的精密减速机构(2)，与所述的减速机构(2)相连接的带一陶瓷芯片(6)的阀芯(10)；感应部件包括一感应器(7)，一由微型芯片程序控制的驱动控制器(9)；驱动控制器(9)与感应器(7)的低压直流电源由电池供电装置(1)提供。本发明的优点是采用特制的微型芯片与微型电机、精密机械传动机构三者科学地组合一体的设计，其结构新颖、性能优异；将感应式水龙头的感应部件与阀门驱动部件采用了一体化配置，使整体结构较为合理、产品造型更小巧、使用更可靠。
