Coupling component 53 will move between the link 71 of first guide duct 343 of main casing 34 and exhaust unit 7, make first annular slope 538 of coupling component 53 engage with the annular slope 715 of link 71 with the annular slippage inclined-plane 348 of first guide duct 343 respectively with second annular slope 539, and, the oblique protruding pin 530 of coupling component 53 is the face 731 that tiltedly supports that pushes part 73 of pushing tow exhaust unit 7, makes to push part 73 and move towards right the direction of frame 31 (promptly away from) together with

movable part

722 and 722 groups of spring elements of establishing 723 of movable part and check spare 724.

Simultaneously, the press part 522 of drivening piece 52 is touch-pressure switch spare 43, makes to make moving cell 4 and switch to actuator state by actuator state not.

At this moment, first of the derivation portion 524 of the drivening piece 52 protruding top section 525 second protruding support segments 536 that are resisted against deserved coupling component 53 linkage part 532; These second protruding top section 526 the 3rd protruding support segments 537 respectively against correspondence; And respectively the 3rd protruding top section 527 is resisted against the first corresponding protruding support segment 535.

And the check spare 724 of the drain tap 72 of exhaust unit 7 is away from the connection mouth 726 of valve body 721; The spring element 723 of drain tap 72 is compressed and has a restoring force.

At this moment, the power spare 41 of making moving cell 4 forms with power source 23 and is electrically connected, take this, power spare 41 can order about rotating component 42 and rotate and then form air-flow, and because second sleeve part 533 bridge joint main casings, 34 first guide ducts 343 of coupling component 53 and the link 71 of exhaust unit 7, therefore gas will be from the flow through exhaust port 727 of valve body 721 of putting chamber 222, the connection mouth 726 of valve body 721, with link 71, the coupling component 53 of control unit 5, first guide duct 343 of main casing 34, air-flow room 341, with second guide duct 344, and the ventilation chamber 311 of frame 31 and the opening 321 of closure panel 32, overflow at last and loose outside frame 31.

Fig. 7, Fig. 8, shown in Figure 9 for another example, when rotation switch piece 51 makes control unit 5 change back stop mode, switch piece 51 is with driving belt moving part 52, make the second protruding top section, 526 pushing and pressing coupling components, 53 linkage part 532 of drivening piece 52 derivation portions 524, and then make coupling component 53 along guide portion 346 together with pusher shoe 54, bridge member 55 and spring element 56 forward (toward air inlet unit 6 directions) move, and make

bridge member

55 and 344 sockets of second guide duct.

Simultaneously, the press part 522 of drivening piece 52 is touch-pressure switch spare 43, makes to make moving cell 4 and switch to not actuator state by actuator state, power spare 41 formed with power source 23 open circuit.

In addition, because the restoring force effect of the spring element 713 of the drain tap 71 of exhaust unit 7 will make movable part 712 move together with check spare 714 forward, check spare 714 takes this to prevent gas leak with the connection mouth 716 of closing valve body 711.

In sum, this air delivery device 21 utilizes control unit 5, casing unit 3, air inlet unit 6, and mechanism design cooperatively interacts between the exhaust unit 7, take this, the user only need look work requirements (inflation or exhaust) and the switch piece 51 of rotation control unit 5 selectively, switch piece 51 promptly can and then drive coupling component 53 together with drivening piece 52 rotations, pusher shoe 54, bridge member 55, and spring element 56 is at stop mode, change between air inlet pattern or the exhaust mode, and order is made moving cell 4 accordingly in not switching between actuator state and the actuator state, just can easily finish inflation or exhaust work, not only high working efficiency and application are good.
