A water valve and a drinking device are provided. The water valve includes an upper support, a lower support, a valve spool, a sealing member, a spring and a water outlet. The upper support is provided with a water inlet. The lower support is provided with a water outlet and a vent hole. The valve spool has a first end connected with the upper support and a second end fixedly connected with the lower support, and the valve spool is movable relative to the upper support, to switch on or off a communication between the water inlet and the water outlet. When the water valve is at a state of discharging water, an interior of the water outlet pipe is not communicated with atmosphere; when the water valve is at a state of not discharging water, the vent hole communicates the interior of the water outlet pipe with the atmosphere.
