With continued reference to fig. 5A-6B, the path switch 12 further includes a driving portion 123 for driving the dynamic portion 122. Preferably, the driving portion 123 is disposed inside the static portion 121 to facilitate reducing the volume of the path switch 12 and improving the degree of integration of the path switch 12. Specifically, the driving portion 123 is held at the lower air duct perforation 12120 of the lower air duct housing 1212 to dispose the driving portion 123 inside the static portion 121.

In this specific example of the steaming device shown in fig. 1 to 7B, the driving part 123 employs an electromagnetic driving scheme to reduce the volume of the passage switch 12 and to keep the air channel 12102 of the static part 121 of the passage switch 12 in a normally closed state, thereby preventing steam or water from entering the hot air generation unit 14 and adhering to the inner wall of the hot air generation unit 14 to form contaminants.

Specifically, the driving portion 123 includes an electromagnetic body 1231, a driving rod 1232, and a reset element 1233, wherein the driving rod 1232 is drivably installed on the electromagnetic body 1231, the reset element 1233 is disposed between the bottom end of the driving rod 1232 and the electromagnetic body 1231, and the dynamic portion 122 is installed on the top end of the driving rod 1232.

When the electromagnet body 1231 is not energized, the return element 1233 remains in the initial condition and the closing cover 1221 of the dynamic portion 122 is kept in the following condition by the actuation rod 1232: the bottom wall of the closing cap 1221 is in contact with the top wall of the upper duct shell 1211, the bottom wall of the closing cap 1221 is in contact with the top wall of the sealing member 1215, and the cap ring 12211 of the closing cap 1221 is held in the annular cap groove 12143 of the steam distribution cap 1214, at which time the duct 12102 of the static portion 121 of the path switch 12 is held in a closed state.

When the electromagnetic body 1231 is energized, the electromagnetic body 1231 drives the driving rod 1232 to drive the dynamic portion 122 to move upward, so that the closing cover 1221 of the dynamic portion 122 is kept in the following state: the bottom wall of the closing cap 1221 and the top wall of the upper duct casing 1211 have a gap, the bottom wall of the closing cap 1221 and the top wall of the sealing member 1215 have a gap, and the cap ring 12211 of the closing cap 1221 is disengaged from the annular cap groove 12143 of the steam distribution cap 1214, at which time the duct 12102 of the static portion 121 of the access switch 12 is maintained in an open state. The bottom end of the driving rod 1232 and the electromagnetic body 1231 press the reset element 1233, so that the reset element 1233 is deformed to accumulate elastic potential energy.

When the electromagnetic body 1231 is powered off, the reset element 1233 returns to the initial state to drive the driving rod 1232 to drive the dynamic portion 122 to move downward, so that the damage 1221 of the dynamic portion 122 remains in the following state: the bottom wall of the closing cap 1221 contacts the top wall of the upper duct casing 1211, the bottom wall of the closing cap 1221 contacts the top wall of the sealing member 1215, and the cap ring 12211 of the closing cap 1221 is held in the annular cap groove 12143 of the steam distribution cap 1214, at which time the duct 12102 of the static portion 121 of the access switch 12 is held in a closed state.

Preferably, the reset element 1233 is a compression spring sleeved on the bottom end of the driving rod 1232, so as to prevent the reset element 1233 from being separated from the bottom end of the driving rod 1232 and the electromagnetic body 1231, thereby ensuring the reliability and stability of the driving part 123.

Further, the dynamic portion 122 includes a mounting element 1222, the mounting element 1222 extending integrally downward from the closure cap 1221, wherein a top end of the actuation rod 1232 is positioned above the mounting element 1222 of the dynamic portion 122.

Further, the driving portion 123 includes an electromagnetic cover 1234, and the electromagnetic cover 1234 is covered outside the electromagnetic body 1231, so that the electromagnetic body 1231 is kept in a relatively closed environment to prevent the hot air entering the air channel 12102 of the static portion 121 from affecting the performance of the electromagnetic body 1231. Meanwhile, the electromagnetic shield 1234 may form the driving part 123 into an integral module to facilitate the assembly of the steaming device.

Fig. 7A shows a cross-sectional state of the steaming device when a steaming function is selected, in which the reset member 1233 of the driving part 123 causes the dynamic part 122 to be maintained in a state of closing the air passage 12102 of the static part 121, the steam generation unit 13 heats water entering the steam generation unit 13 from the water tank 30 to be converted into steam, and the steam is guided from the bottom of the steaming container 20 into the functional space 21 of the steaming container 20 by the air passage 12101 of the static part 121 of the passage switch 12 to steam food placed in the functional space 21 of the steaming container 20.

Fig. 7B shows a cross-sectional view of the steaming device when the drying function is selected, wherein the electromagnetic body 1231 and the driving lever 1232 of the driving part 123 cooperate with each other to drive the closing cover 1221 of the dynamic part 122 to move upward to open the air channel 12102 of the static part 121, and the hot air generated by heating the air by the hot air generating unit 14 is guided by the air channel 12102 of the static part 121 of the passage switch 12 from the bottom of the steaming container 20 into the functional space 21 of the steaming container 20 to steam the goods placed in the functional space 21 of the steaming container 20.

It is worth mentioning that the steam generating unit 13 is kept in a power-off or standby state to avoid generating steam when the steaming device is selected to the drying mode. When the steaming device is selected to the drying mode, the steam passage 12101 of the static portion 121 of the path switch 12 is in an open state, and at this time, hot air can enter the steam passage 12101 of the static portion 121 of the path switch 12 to dry moisture attached to the inner wall of the steam guide column 1213 of the static portion 121 to secure the sanitation of the steaming device.
