The ball 313 rotates to connect the water inlet 3111 and the water outlet 3112, and blocks the drain 3113. Water flows in from the water inlet 3111, and the water passes through the ball. When inside 313, the thermistor 315 senses the temperature of the water source and converts it into an electrical signal and transmits it to the controller body 3144. If the water source temperature is close to or below zero degrees, the controller body 3144 controls the output shaft of the rotating motor 3141 to rotate in the opposite direction, thereby driving the sphere 313 to rotate in the opposite direction.
