Embodiment
Embodiment 1:
The structural representation of the embodiment of the invention is shown in Fig. 3,4,5,6, fan structure of the present invention, include base 2 and be installed in shell 1 on the base 2, wherein be provided with the intake grill that to open fan between base 2 and the shell 1 and close the elevator mechanism of the intake grill of fan.
Above-mentioned elevator mechanism includes drive motor 3 and will rotatablely move and is converted into straight-line driving mechanism, wherein drive motor 3 is installed on the base 2, the driving link 4 of driving mechanism is connected with the output shaft of drive motor 3, and the driven member 6 of driving mechanism is connected with shell 1.In the present embodiment, above-mentionedly will rotatablely move that to be converted into straight-line driving mechanism be the worm rack driving mechanism, the driving link 4 of driving mechanism is a worm screw, and driven member 6 is a tooth bar, and worm screw is identical with the modulus of tooth bar.
In the present embodiment, the lifting height of above-mentioned shell 1 is by controlling the working time of controlling and driving motor 3.
In addition, for ease of the stroke that control shell 1 moves downward, above-mentioned shell 1 is provided with control, and it moves to the lower position-arresting control mechanism that intake grill is closed and stopped to move downward.In the present embodiment, above-mentioned lower position-arresting control mechanism includes the position limit switch 5 that is fixedly mounted on the base 2 and is arranged on the shell 1, can triggers the rib 8 of position limit switch 5, and the signal output part of position limit switch 5 is connected with the signal output part of drive motor 3.In addition, also be provided with on the above-mentioned position limit switch 5 and be convenient to the position limit switch shell fragment 9 that contacts with rib 8.
For guaranteeing to slide mutually freely between shell 1 and the base 2.Also be provided with rail slot 7 on the above-mentioned shell 1, base 2 is provided with slide rail 10, and the rail slot 7 that is provided with on the slide rail 10 on the base 2 and the shell 1 matches and forms the guide rail structure that can slide mutually each other.
In the present embodiment, above-mentioned drive motor 3 is screwed on the set screw post 11 of base 2.
Working principle of the present invention is as follows: during the fan start, drive motor 3 operations drive driving link 4 rotations of driving mechanism, and driving link 4 rotations just drive driven member 6 and move upward, because driven member 6 and shell 1 are fixed as one, the movement locus of driven member 6 is the movement locus of shell 1 just.In like manner, during shutdown, drive motor 3 antiports, drive driving link 4 counterrotatings, drive driven member 6 and shell 1 and move downward, when the rib on the shell 18 drops to the position limit switch shell fragment 9 that triggers on the position limit switch 5, shell 1 just stops to descend, at this moment, shell 1 just descends and has put in place, and intake grill has also been closed.
When shell 1 of the present invention descends, triggering position limit switches 5 by rib 8 judges whether shell 1 descends and puts in place, when shell 1 rises, position limit switch is not set judges whether shell 1 rises and put in place, but the lifting height of controlling shell 1 working time by fan governor controlling and driving motor 3.
