摘要： 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.

摘要： A showerhead including a connection base and a surface cover assembly, with a water outflow cavity formed therebetween. The surface cover assembly has a water discharging hole, and includes a surface cover body and a water outflow surface cover that are mounted and connected on the connection base. The water outflow surface cover has a water outflow hole, the lower periphery of which extends downward to form a water outflow port. The water outflow surface cover is attached against the upper face of the surface cover body, and the water outflow port passes through the surface cover body. The upper periphery of the water outflow hole extends upwards to form a water blocking peripheral wall. The showerhead also includes a valve that cooperates with the water discharge hole to close and open the water discharge hole when the water supply is on and off, respectively.

摘要： A switching valve spool has a fixed shaft and a switching shaft coaxially arranged within. The switching shaft is linked with an operating unit and moves between a first, second, and third position in the fixed shaft along the axis. The switching shaft has an inlet and an outlet. In the first position of the switching shaft, the inlet is closed; in the second position of the switching shaft, the inlet is open and an air intake is formed between the side wall of the switching shaft closing to the outlet and the fixed shaft, when the water flows into the fixed shaft from the outlet, the air sucked from the air intake mixes with the water in the fixed shaft, because the fixed shaft diameter is larger than the outlet diameter; in the third position of the switching shaft, the inlet remains open and the air intake is closed.
