, all using soft plastic material, such as Du Pont PTEE, to reduce noise for described cover plate third wheel 512 and seat ring third wheel 612.
In addition, in this utility model, cover plate active wheels 51 and seat ring active wheels 61, cover plate ratchet assembly 52 and seat ring
Gear in ratchet assembly 62, cover plate driven wheels 53 and seat ring driven wheels 63 is symmetricly set on the both sides of middle splint 4, and
Coaxially it is fixed in the perforation of middle splint 4 by rotating shaft respectively, with digging by controller Driven by Coaxial cover plate and seat ring
Or put down it is ensured that both actions are consistent, make the process dug or put down of cover plate and seat ring more attractive in appearance.
Because cover plate drive wheel group 5 of the present utility model is the same with the 26S Proteasome Structure and Function of seat ring drive wheel group 6, simply
Gear in both axle centered on middle splint 4, symmetrically distribution, therefore when drive cover plate and seat ring dig simultaneously or
When putting down, both gear direction of rotation are contrary.Therefore only taking cover plate drive wheel group 5 as a example illustrate how to dig and put down lid below
The work process of plate.
When the cover plate needing to dig intellectual water closet, described controller first reads cover plate angle detection components 7 transmission
Signal, to judge whether cover plate has already turned on, if angle is detected to be more than 90 ° and more than 1 second, sets cover plate as opening mark
Will position, if angle is detected to be less than 10 ° and more than 1 second, sets cover plate as opening Flag Reset.If detected at cover plate
In opening flag bit, then exit the program of opening, otherwise, described controller sends pwm signal to described cover plate motor 2, controls
Cover plate processed is dug.Specifically, described controller controls described cover plate motor 2 to rotate forward, and then drives described cover plate sliding tooth
Wheel 511 rotation, described cover plate driving gear 511 sequentially drives the cover plate third wheel 512 of engagement, cover plate ratchet 523 to rotate, described lid
The rotation of plate ratchet 523 drives cover plate non return part 523, cover plate pawl axis tooth 522 to rotate clockwise again, described cover plate pawl axis tooth
522 continue to drive the first cover plate driven pulley 531, the second cover plate driven pulley 532 and the 3rd cover plate driven pulley 533 of engagement to rotate,
Thus driving cover plate output revolving shaft 54 to rotate, and then realize digging of cover plate.And during digging cover plate, if opening angle
Degree is less than 70 °, then described controller controls the pwm signal of output 100%, controls described cover plate motor 2 quick rotation, from
And accelerate the angle dug；If open angle is more than 70 °, described controller, by certain program, automatically adjusts output
The pwm signal of 5-100%, make speed that the angular velocity opened is maintained at 8 ° per second it is ensured that open the continuous of cover plate and seat ring and
Steadily；If open angle is more than 90 °, the execution brake of 0.2 second runs, and stops described cover plate motor 2 and rotates, and then
Stop continuing to dig cover plate.
During digging cover plate, if cover plate runs into external force stall, that is, external force is passed by cover plate output revolving shaft 54
When being directed at cover plate driven wheels 53, then acting on cover plate pawl axis tooth 522 by cover plate driven wheels 53, described cover plate pawl axis tooth
522 stop operating, and then drive described cover plate non return part 521 to stop operating, and described cover plate ratchet 523 drives in described cover plate
In the presence of motor 2, continue to keep operating, and extrude cover plate projection A on described cover plate non return part 521, and by described lid
Plate projection A toward the center side compression of described cover plate non return part 521, with cross described cover plate projection A and in described cover plate non return part
Slide on 521, and with the rubbing action of described cover plate non-return portion 5212 under and gradually slow down so that described cover plate ratchet 523
Will not be affected by external force and stop operating or invert, and then also make external force will not directly act on cover plate motor 2, be had
Effect prevents cover plate motor 2 to invert, thus playing a cushioning effect to described cover plate motor 2.And work as described control
Device processed detects the signal having exported more than 10%PWM, and the time of renovating more than more than 2 seconds, and described cover plate angle
The speed that the angular velocity of detection components 7 detection is less than 1 ° per second, when this speed also maintains the time of more than 1 second, then described control
Device processed judges to receive external force effect, and now described controller sends 2% pwm signal to described cover plate motor 2, allows lid
Plate motor 2 gradually stops, and output simultaneously is equivalent to 2Kgf.cm power and lifts cover plate so that cover plate slowly falls, it is to avoid
Cover plate directly drops and damages closet body, or crushes people.
When putting down cover plate, described controller detects cover plate and has already turned on, then described controller sends 60% pwm signal
Drive described cover plate motor 2 to invert, be equivalent to the thrust of the downward 15Kgf.cm of cover plate.When the angle that cover plate falls is less than
When 80 °, described controller controls the stop motion of described cover plate motor 2, and cover plate leans on own wt to fall, when cover plate whereabouts
When angle is less than 20 °, the pwm signal that described controller sends 2% controls described cover plate motor 2 to rotate forward, and is equivalent to upwards
About 2Kgf.cm power lifts cover plate, and now cover plate, under the action of gravity of itself, continues slow whereabouts.The angle falling when cover plate
When degree is less than 5 °, described controller controls the intervalometer of the reset parameter run and timing, completes to put down the operation of cover plate.
Compared to prior art, this utility model avoids cover plate or seat by cover plate ratchet assembly and seat ring ratchet assembly
When circle is subject to counteracting force, and cover plate motor or the reversion of seat ring motor is made to burn out it is ensured that cover plate motor
Normal use with seat ring motor and each gear.Further, the cover plate being coaxially disposed is controlled by controller simultaneously
Motor and the rotation of seat ring motor, so can control simultaneously cover plate and seat ring dig or put down so that both
Action keeps relatively uniform and seems more attractive in appearance.
Meanwhile, the cover plate third wheel made using soft plastic material and seat ring third wheel, can greatly reduce noise.Further,
Torsion spring is arranged on seat ring, seat ring motor can be assisted to drive the big seat ring of weight to dig or put down, decrease seat ring and drive
The burden of motor.
This utility model is not limited to above-mentioned embodiment, if do not taken off to various changes of the present utility model or deformation
From spirit and scope of the present utility model, if these are changed and deformation belongs to claim of the present utility model and equivalent technologies
Within the scope of, then this utility model is also intended to comprise these changes and deforms.
