Abstract
A switching valve for discharging cold water includes: an operating member, a first switching member, and a water outlet switching member. The switching valve for discharging cold water has a cold water discharging passage and a head water outflow passage. When the operating member is in the initial position, the switching valve for discharging cold water is in the first position, the joint between the head water outflow passage and the water inlet end is sealed, the cold water discharging passage opens; when the operating member switches to the shower position, the first switching member is moved by the operating member to the second position, a second joint between the cold water discharging passage and the water inlet end is sealed, and the head water outflow passage opens, engaging the operating member with the water outlet switching member. The operating member drives the water outlet switching member to open one or both of the first and second water outlet passages.
