Inductance type pull down faucet
The invention discloses an inductance type pull down faucet. The inductance type pull down faucet comprises a faucet body, a pull down pipe, a pull down head, a control valve and a switch assembly, wherein the faucet body is provided with a pull down channel; the pull down pipe is movably arranged in the pull down channel in a penetrating mode and is provided with a water outlet channel, and the pull down head is connected with the water outlet end of the pull down pipe; the control valve is used for controlling the connection and disconnection of the water outlet channel, and the switch assembly is electrically connected with the control valve and comprises a metal object and an induction coil; the metal object is fixedly arranged relative to one of the faucet body and the pull down pipe, the induction coil is fixedly arranged relative to the other one of the faucet body and the pull down pipe, and in the pull down process of the pull down pipe, when the attenuation value or the inductance value of an alternating magnetic field generated when the metal object is close to or away from the induction coil reaches a preset value, the control valve controls the water outlet channel to be opened or closed. According to the scheme, the switch assembly has no sliding contact, is not affected by dust and other non-metal factors in the working process, is low in power consumption and long in service life and can be used under various severe conditions.
本发明公开了一种电感式抽拉龙头，包括龙头本体，设有抽拉通道；抽拉管，可移动的穿设于抽拉通道，并设有出水通道；抽拉头，与抽拉管的出水端相连接；控制阀，用于控制出水通道的通断；开关组件，与控制阀电连接，开关组件包括金属物体和感应线圈；其中，金属物体相对于龙头本体和抽拉管两者之一固定设置，感应线圈相对于龙头本体和抽拉管两者之另一固定设置，抽拉管抽拉过程中，金属物体靠近或远离感应线圈产生的交变磁场衰减值或电感值达到预设值时，控制阀控制出水通道打开或关闭，本方案的开关组件具有无滑动触点,工作时不受灰尘等非金属因素的影响,并且低功耗,长寿命,可使用在各种恶劣条件下。
