As shown in Figure 1, when the room temperature decreases within the phase transition temperature range of the memory alloy spring, the memory alloy spring can be shortened, and the second end of the memory alloy spring can drive the valve 5 to a direction close to the first end of the memory alloy spring. The movement gradually reduces the contact area between the valve 5 and the cross-section of the water flow channel in the water inlet pipe, thereby increasing the water flow conductance of the water inlet pipe 6 .

The memory alloy is a martensitic phase transformation alloy with regular atomic arrangement and small volume. This alloy deforms under the action of external force at low temperature. When the external force is removed and heated to a certain temperature, it can recover original shape. Because this alloy has a recovery function of more than a million times, it is called "memory alloy". Moreover, memory alloys also have the advantages of wear resistance, corrosion resistance, and non-toxicity, so they are widely used. Among them, the shape memory alloy has a shape memory effect. Taking the spring made of memory alloy as an example, if the spring is placed in hot water, the length of the spring will elongate immediately, and then put in cold water, it will immediately return to its original shape.
