Abstract
A faucet includes a faucet body, a control knob, a follower and a switching valve. The faucet body has a water inlet, a water outlet and a switching port. The switching valve includes a driven rod moved with the control knob, a sealing plate having a plurality of connecting holes, a pressure release plate detachably pressing the sealing plate, and an elastic member mounted between the sealing plate and the pressure release plate. Thus, the switching valve can release the water pressure in the faucet body automatically so that the sealing plate is moved downward by its gravity to detach from the switching port, and the water inlet, the switching port and the water outlet are connected at a normal state to allow passage of water to prevent the water from being introduced into the shower head at the next usage.
