The pendulum of the pendulum wheel rotates to cross the side contact of first actuating lever and second actuating lever, do not contact with the drive inclined plane of first actuating lever upper end, first actuating lever upwards returns under reset spring's effect and moves to the pendulum next movement path of pendulum wheel, the pendulum wheel is blocked by the second actuating lever and can not rotate, step motor continuously rotates, make intermittent type nature holds power transmission mechanism holds the power, when the accelerating rod moves to the second actuating lever direction, the stay cord of accelerating rod extrusion second actuating lever one side, pull down the first actuating lever a distance through corresponding stay cord, so that the pendulum of pendulum wheel and the drive inclined plane contact of first actuating lever, make the pendulum wheel continue to rotate, through the intermittent type nature holds power transmission mechanism of lasting power before quick release, promote the pendulum wheel and rotate fast, thereby make the second actuating lever descend fast, and through the acceleration inclined plane extrusion accelerating rod of second actuating lever, make the accelerating rod move to first actuating lever direction, and drive the blade that cuts down to first actuating lever direction, if this circulation effect makes and two and cuts open and make a round trip under the effect and cut-off the wind gap.
The working principle of the invention is as follows: referring to fig. 1, in the high-speed cut-off type air conditioner air supply device provided by the invention, in an initial state, a cut-off blade 2 is positioned at the center of a driving frame 4, an electromagnet is not contacted with a starting block 205, and at the moment, two air outlets 101 on a frame base 1 are closed by a blade surface 201.
When the equipment is started, the electromagnet is powered off, the starting block 205 is pushed to move to one side, the stepping motor 12 drives the first sheave 11 connected with the starting block to drive the second sheave 9 to rotate, the first gear rotates, the first gear drives the pendulum wheel 7 to rotate through the second gear, when the pendulum of the pendulum wheel contacts with the side face of the driving rod but does not contact with the driving inclined plane at the upper end of the driving rod, the first gear and the second gear are blocked by the driving rod along with the pendulum wheel and can not rotate, and the second sheave continues to intermittently rotate, so that the spiral spring between the second sheave and the first gear stores force; when the driving rod descends for a certain distance, the pendulum of the pendulum wheel is contacted with the driving inclined plane at the upper end of the driving rod, the pendulum wheel drives the driving rod to move downwards through the pendulum on the pendulum wheel, the clamping stagnation of the pendulum wheel is relieved, the first gear, the pendulum wheel and the second gear on the pendulum wheel can start to rotate, the first gear, the pendulum wheel and the second gear on the pendulum wheel instantly rotate rapidly due to the continuous compression and the accumulation force of the spiral spring before, the pendulum wheel drives the driving rod to instantly move downwards, the driving rod is accelerated to instantly move rapidly, and the cutting blade is driven to move more rapidly through the transverse push-pull transmission mechanism, so that the quick high-frequency cutting of an air outlet is formed;
The stepper motor 12 rotates at a low speed all the time due to the existence of the spiral spring, but after the compression of the spiral spring is completed, larger acting force is not given to the large gear any more; the coil spring pressed at this time gives a rotational driving force to the large gear, and then transmits the driving force to the pinion 702 at the upper part of the balance weight 7 engaged therewith, so that the balance weight is kept in a rotated state by the driving force, but since the straight section of the left driving lever 6 is in contact with the balance weight 701 at this time, the driving lever 6 cannot be pressed down along the driving lever movement groove 402 by the force of the balance weight 701, and thus the balance weight 7 is caught at this time and cannot be smoothly rotated. At this time, the accelerator 203 is given a leftward force to move in the accelerator movement groove 403, when approaching the left driving rod 6, the accelerator is firstly contacted with a pulling rope (not shown in the figure), at this time, the pulling rope is pressed and bent by the accelerator 203 in an initial straight state, and further the left driving rod 6 connected with the accelerator is driven to press the return spring 5 downwards along the driving rod movement groove 402, although the left driving rod 6 moves only a small distance, the driving inclined surface 604 of the left driving rod 6 is contacted with the pendulum 701, the pressure given by the pendulum to the driving inclined surface 604 causes the return spring 5 to be further pressed downwards along the driving rod movement groove 402, at this time, the accelerator 203 moves to the accelerating inclined surface 602, the speed is reduced to 0 under the action of the accelerating inclined surface 602 and the reciprocating spring 3, and the accelerator is reversely accelerated, so that the accelerator 203 moves rightward, and thereafter the left air outlet 101 is opened.
After the balance weight 7 presses the left driving rod 6, the balance weight 7 rotates a certain angle, when the balance weight 7 no longer presses the left driving rod 6, the reset spring 5 releases elastic potential energy, so that the left driving rod 6 is reset, and then the balance weight 7 contacts the straight section of the right driving rod 6, and the driving rod 6 cannot be pressed downwards along the driving rod movement groove 402 due to the acting force of the balance weight 701, so that the balance weight 7 is clamped and cannot smoothly rotate. At this time, the left driving lever 6 is located in the middle space of two adjacent pendulums 701 and is not in contact with any of the pendulums. When the accelerator lever 203 moves to the far right, the operation principle is the same as that of the left, so that the right driving lever 6 moves down and moves leftward by the acceleration ramp 602 of the right driving lever 6. At this time, the left air outlet 101 is closed and the right air outlet 101 is opened. The reciprocating motion is performed in such a way as to realize the left-right reciprocating motion of the cutoff blade 2, thereby realizing the opening and closing of the air outlet 101.
