The working principle or the using method is as follows:
after the detection module 5 detects that dust is accumulated to a certain degree, the electromagnetic wind deflector 44 is controlled to be opened, so that the fan 41 is in direct contact with airflow flowing through the air duct main body 1, and thus the fan starts to rotate under the action of the airflow, so that the air pump 43 is driven to rotate, so that the air bag 22 is inflated, the sliding plate 21 slides upwards under the action of the air bag 22, so that the upper wind deflector 23 is driven to slide downwards, and when the sliding plate 21 rises to the highest point, the lower bottom surface of the upper wind deflector 23 just props against the upper bottom surface of the sliding plate 21, so that the upper space of the air duct main body 1 is closed, so that the airflow can only pass through a channel just below the newly opened sliding plate 21, and the air pump 41 is provided with a safety valve, and when air cannot be filled into the air bag 22, the airflow is automatically discharged outwards.
In the process that the sliding plate 21 rises, the sliding plate drives the lower scraping and sweeping plate 312 to slide upwards together, when the limiting point is reached, the sliding plate is pushed against one end of the second flexible shaft 316, the other end of the second flexible shaft is pushed forwards, the telescopic guide plate 314 is driven to be pushed forwards, meanwhile, the sliding plate 21 slides upwards, the pressure contact of the sliding plate and the pressure contact switch disappears, the pressure contact switch controls the electromagnetic sliding plate at the upper end of the ash falling groove 211 to be opened, and meanwhile, the electromagnetic sliding plate at the lower end is closed.
When the roller 321 contacts the driving wheel 42, it starts to rotate under the driving of the driving wheel 42, so as to be pulled by the pull rope 33 to slide forward, at this time, the four sides of the sweeping board 31 sweep the upper closed space of the air duct body 1, and the telescopic guide plate 314 makes the dust scraped from the upper wall fall on the front end of the sweeping board 31, when the sweeping board 31 slides forward to the front end, the scraped dust is pushed forward into the dust falling groove 211 under the action of the sweeping board 31, and the sweeping board 31 contacts the top contact switch, so as to control the electromagnetic wind shield 44 to close, so as to stop the fan 41 rotating, at this time, the air in the air bag 22 is discharged outward under the action of the self gravity of the sliding board 21, so as to make the sliding block 21 slide downward, and during the descending process, the sweeping board 312 slides downward to return to the initial state along with the sliding block 21 under the action of the first elastic member 317, therefore, the retractable guide plate 314 retracts backwards under the action of the second elastic member 318, so that the dust of the retractable guide plate 314 directly falls into the dust falling groove 211 below, the roller 321 is separated from the driving wheel 42 to be in top contact, the power of the roller wire coil 32 disappears, and the sweeping plate 31 slides backwards under the action of the third elastic member 15 to recover to the initial position.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
