The cross sections of the carding plates 503 are curved surfaces, and the elevator body 2 is electrically connected with the voice controller 6.
When the elevator is used, when a user needs to enter the elevator body 2, firstly, the user presses a leftmost button of the connecting frame 1 so as to enable the elevator body 2 to stop, then when the elevator body 2 is gradually stopped, the user enters the elevator body 2, when the user completely enters the elevator body 2 and the elevator movable door 3 is in a closed state, the user can transmit the spoken sound to the inside of the voice controller 6, and then the voice controller 6 is used for controlling the elevator body 2 to move, so that the user can conveniently control the elevator body 2 without touching the elevator body by hands;
in the above working process, since the elevator movable door 3 synchronously drives the fixed connection shell 401 to move in the process of opening and moving, when the fixed connection shell 401 starts to move, the rotating connection plate 402 and the restoring telescopic spring 403 are synchronously driven to move in the process of moving, the rotating connection plate 402 synchronously drives the arc guide rod 405 to move in the process of moving, when the arc guide rod 405 contacts with the positioning rod 406, the arc guide rod 405 firstly receives the limiting force of the positioning rod 406 to enable the arc guide rod 405 to start rotating, the arc guide rod 405 synchronously drives the restoring telescopic spring 403 to stretch in the rotating process, when the moving distance of the elevator movable door 3 is gradually increased, the arc guide rod 405 also slides over the outer surface of the positioning rod 406, meanwhile, the restoring telescopic spring 403 rapidly compresses, the restoring telescopic spring 403 synchronously drives the fixed rod 407 and the long slat 408 to rapidly move in the compressing and resetting process, and the long slat 402 simultaneously drives the cleaning soft brush 409 to clean the bottom of the voice controller 6 in the accelerating process, so that the voice controller 6 is prevented from being blocked by the voice controller 6, and the voice is prevented from being blocked by the voice controller 6 due to the fact that the voice is easy to be exposed in the process of the voice controller is easy to be less in the environment;
in the working process, because the rotating connection plate 402 can quickly make acceleration, when the rotating connection plate 402 rotates to the limit of restoring the traction force of the telescopic spring 403, the sliding connection plate 501 can slide in the same direction through the inertia of the rotating connection plate, meanwhile, the connecting long plate 502 can slide in the same direction, the connecting long plate 502 can synchronously drive the carding plate 503 to move in the sliding process, then the carding plate 503 can screen the inside of the cleaning soft brush 409 so as to enable impurities and dust in the cleaning soft brush 409 to fall off, and the design of synchronously moving the sliding connection plate 501 can block the impurities and dust swept by the cleaning soft brush 409 so as to facilitate the subsequent collecting work, prevent the blocked impurities and dust from scattering in the elevator body 2, so that the situation that a user is difficult to make sound and the voice controller 6 is inaccurate in recognition occurs, and ensure the normal use of the voice controller 6;
in the above working process, since the sliding connection plate 501 continuously slides left and right, the knocked-down impurities and dust will fall between the two cleaning soft brushes 409, namely the top of the sliding connection plate 501, and the sliding connection plate 501 can scrape and collect the impurities and dust into the collecting shell 410 through the through groove in the sliding process, thereby being convenient for collecting the impurities and dust, on one hand, avoiding the problem that the staff needs to clean the voice controller 6 regularly, and on the other hand, avoiding the defect that the pick-up of the voice controller 6 is smaller and smaller due to the continuous increment of the dust and the impurities in the using process;
in the above-mentioned course of working, because elevator dodge gate 3 can drive fixed connection shell 401 and restore the extension spring 403 and remove in step, so fixed connection shell 401 and restore the extension spring 403 and will get into inside spread groove 404 together to can avoid elevator dodge gate 3 to be difficult to the problem of opening completely, when needs take out impurity and dust after collecting, the staff inserts the pulling inslot with the finger this moment inside, then outwards pulls collection shell 410 and can drive the removal of impurity and dust, later will collect the impurity and the dust of shell 410 inside and pour out, thereby can reach the clean work to elevator body 2 inside, prevent dust and impurity messy splash and cause the problem that the user is difficult to the sound in elevator dodge gate 3 inside to appear.
