A certain gap exists between the air inlet plug 223 and the air inlet valve penetrating channel 530, which can prevent fresh air from violently flowing into the valve component bin 500 to cause the temperature fluctuation of the air inlet memory alloy wire 230, thereby ensuring the stable temperature rise and deformation of the air inlet memory alloy wire 230, and can ensure that the valve component bin 500 and the U-shaped air passage 600 can normally exchange heat after the power of the air inlet energizing terminal 210 is cut off, thereby preventing the heat accumulation of the valve component bin 500.
As shown in fig. 9, a lower vent valve gap 512 is opened on the sidewall of the valve assembly chamber seat 510 facing the vent 143, and an upper vent valve gap 522 is opened at the corresponding position of the valve assembly chamber cover 520 to form a vent valve insertion passage 540 after the cover is closed; the exhaust plug 323 is smaller than the exhaust valve insertion passage 540 to pass through the exhaust valve insertion passage 540 when the exhaust memory alloy wire connection portion 322 is pulled toward the exhaust energizing terminal 310. Referring to fig. 9, the exhaust plug 323 is slightly smaller than the exhaust valve insertion channel 540, and does not collide with the wall after being pulled obliquely. A certain gap exists between the exhaust plug 323 and the exhaust valve through-mounting channel 540, which can prevent fresh air from violently flowing into the valve assembly bin 500 to cause the temperature fluctuation of the exhaust memory alloy wire 330, thereby ensuring the stable temperature rise and deformation of the exhaust memory alloy wire 330, and can ensure that the valve assembly bin 500 and the U-shaped air passage 600 can normally exchange heat after the exhaust power-on terminal 310 is powered off to prevent the heat accumulation of the valve assembly bin 500.
