Abstract: A relief valve for overload protection includes a switching member disposed at the inlet, and a guide pillar in sealed connection with the switching member. The guide pillar is provided with a first water outlet and a second water outlet disposed in the direction of water flowing, and a slidable sleeve is disposed on an outer side of said guide pillar. When the water pipe connected to the outlet cracks, the water pressure at said outlet may drop, which leads to further movement of said slidable sleeve towards the outlet and cause the plug disposed on the top of said slidable sleeve to plug the outlet in a sealed manner, thus closing the outlet.

Abstract: A human body sensitive, touch-controlled water outlet device includes: a faucet body, a cold water inlet, a hot water inlet and a switch unit, with the switch unit including a touch sensitive module, a control module and a power source module. When a human body touches the switch control sensing zone or the water temperature switchover zone arranged on the faucet body, the touch sensitive module identifies the touch signal and outputs a corresponding sensed signal to the control module, and then the control module controls the water outlet device according to the sensed signal, so as to open or close the water outlet device and provide the selected type of outlet water. Further disclosed is a method for controlling the human body sensitive, touch-controlled water outlet device. The human body sensitive, touch-controlled water outlet device is convenient to use and has a high touch control precision.
