Embodiment：
As shown in Figure 1, a kind of automatic air control system that power domain uses, includes the shell 1 of inner hollow, it is described
Pneumatic mechanism, holder 13 and mounting base 17 are provided in shell 1, mounting base 17 and the inner wall of shell 1 are fixed, and mounting base 17 is arranged
Between holder 13 and pneumatic mechanism, pneumatic mechanism is connected with link mechanism 15, link mechanism 15 pass through after mounting base 17 with branch
Frame 13 connects, and pressure head 11 is provided in holder 13, pressure head 11 is connected with contact plate 9, and contact plate 9 is from holder 13 far from pneumatic motor
Holder 13 is stretched out in one end of structure, and contact 1 and dead axle fulcrum 10 are equipped in contact plate 9, and contact 1 is arranged in holder 13
Outside, dead axle fulcrum 10 are arranged inside holder 13, arc-shaped slot 5 are provided in holder 13, axis pin is provided in arc-shaped slot 5
6, axis pin 6 passes through contact plate 9, and contact plate 9 can be rotated around axis pin 6, and axis pin 6 can be in arc-shaped slot 5 along arc
The cambered surface of straight slot 5 moves, and spring 4 is provided between pressure head 11 and holder 13, and 4 one end of spring is fixed with holder 13, the other end
It is connected with spring branch piece 12, and spring branch piece 12 is connect with pressure head 11, telescopic rod 14 is provided between pressure head 11 and holder 13, is stretched
Between contracting bar 14 and pressure head 11, hinge, and hinge and corresponding telescopic rod 14, pressure are both provided between telescopic rod 14 and holder 13
First 11 or holder 13 connect, telescopic rod 14 is arranged in the top of spring 4, is provided with contact 27 within the case 1, and contact 27 is arranged
In the lower section of contact 1, and contact 1 can be contacted with contact 27 when contact plate 9 is rotated around axis pin 6；The pneumatic mechanism
Cylinder 18 including interconnection and air pump 3, and cylinder 18 is connect with link mechanism 15, is arranged between cylinder 18 and holder 13
There are protective cover 16, protective cover 16 to be connect simultaneously with cylinder 18 and holder 13；Current inductor is installed on the outer wall of the shell 1
2, and current inductor 2 is connect with air pump 3.When close a switch bakelite handle when, current inductor 2 detects that electric current passes through, give gas
Pump 3 signals so that air pump 3 starts, and cylinder 18 is inflated, link mechanism 15 is driven to move, and contact plate 9 is pushed to move, and contact 1 is
Moving contact, contact 27 are static contact, and contact 1 is made to generate the trend being closed with contact 27, in this motion process, holder 13
