Control stick 33 is rotated.
First operating position and the second operating position
Fig. 6 shows that working condition of the sliding panel 20 of the air channel switching device 1 shown in Fig. 1 in the first operating position is illustrated
Figure.Fig. 7 shows the working state schematic representation of the sliding panel 20 in the second operating position of the air channel switching device 1 shown in Fig. 1.Its
The lines with arrow in middle Fig. 6 and Fig. 7 represent airflow direction.
As shown in fig. 6, in the present embodiment, in the first operating position, first row interface and second row interface are just pair simultaneously
Dock correspondingly.Specifically, positioned at first row interface the other end the first air entry 131 and the second connecting port 21 pairs
Connect and connect, the first connecting port 11 is docked and connected with the second working interface 232 of the other end positioned at second row interface, except the
Air entry 12 (i.e. the second air entry 122) beyond one air entry 121 and the working interface 23 in addition to the second working interface 232
(i.e. the first working interface 231) is docked and connected, and the first inflatable mouth 131 is docked and connected with the first air interface 221, and second blows
QI KOU 132 is docked and connected with the second air interface 222.In this case, because the first air entry 131 is negative with blower fan 1
Pressurized air source couples, and the second connecting port 21 connects with the first connecting port 11, therefore, the second working interface 232 and blower fan 1
Negative pressure source of the gas connection, the second working interface 232 can to work platformses provide negative pressure output (i.e. absorption affinity).Further, since
Second air entry 122 couples with the negative pressure source of the gas of blower fan 2 so that the first working interface 231 is connected with the negative pressure source of the gas of blower fan 2,
Therefore, the first working interface 231 can also provide negative pressure output (i.e. absorption affinity) to work platformses.
