The stepping motor 41 rotates forward to drive the second ratchet wheel 44 to rotate forward, the second ratchet wheel 44 and the second pawl 462 are matched to drive the second ratchet sleeve 46 to rotate forward, the second ratchet sleeve 46 drives the driving gear 461 to rotate forward to drive the roller gear 24 to rotate forward, the roller gear 24 drives the cat litter roller 2 to rotate, and the sliding block 71 starts to slide in the first sliding groove 25.
During the rotation process, when the roller opening 22 is gradually close to the lower end of the shell 1, the sliding block 71 slides from the first sliding groove 25 to the second sliding groove 26, and the two waste box covers 7 are gradually separated; meanwhile, the cat litter and the excrement roll in the cat litter roller 2 together, then the cat litter and the excrement roll on the filter plate 23, the cat litter enters the filter tank 231 through the filter plate 23, and the excrement is blocked on the filter plate 23; then the cat litter roller 2 continues to roll, and excrement rolls from the filter plate 23 to the position of the roller opening 22 and falls into the waste material box 6; the litter drum 2 continues to rotate, when the drum opening 22 gradually gets away from the lower end of the housing 1, the sliding block 71 slides from the second sliding groove 26 into the first sliding groove 25, and the two waste box covers 7 gradually get close to seal the waste box 6; meanwhile, the cat litter in the filter tank 231 gradually returns to the inside of the cat litter drum 2 again through the filter plate 23; the drum opening 22 communicates with the litter outlet 311 again, the stepping motor 41 stops forwarding, and the cleaning operation is completed.
After the cleaning operation is completed, if the gravity sensing device 8 detects that the quality of the cat litter drum 2 is higher than the first set value, the motor 41 stops operating.
If the gravity sensing device 8 detects that the mass in the cat litter drum 2 is lower than the second set value, the gravity sensing device 8 controls the motor 41 to rotate reversely by a certain angle.
The first set value is greater than the second set value.
The stepping motor 41 drives the first ratchet wheel 43 to rotate reversely, the first ratchet wheel 43 and the first pawl 452 are matched to drive the first ratchet wheel sleeve 45 to rotate reversely, and the end face gear 451 drives the feeding part driving gear 33 to rotate so as to drive the feeding part 32 to rotate for a certain angle; after the feed chute 322 communicates the end face opening 341 with the litter outlet 311, clean litter falls from the end face opening 341 through the feed chute 322, the litter outlet 311, and the drum opening 22 into the litter drum 2; the above steps are repeated until the gravity sensing device 8 detects that the quality in the cat litter roller 2 is higher than a first set value, and the feeding work can be completed.
The cat leaves litter cylinder 2 next time, and gravity induction system detects the cat and leaves, repeats above-mentioned step.
According to the invention, the first ratchet wheel 43, the end face gear 45, the second ratchet wheel 44 and the driving gear 46 are arranged, so that when the motor 41 rotates forwards, the driving gear 46 drives the litter roller 2 to rotate for cleaning, the feeding component 3 does not work, when the motor 41 rotates backwards, the end face gear 45 drives the feeding component 3 to work, the driving component 4 does not work, and the litter roller 2 does not rotate.
According to the cat litter box, the roller opening 22 is arranged, so that excrement falls into the waste box 6 through the roller opening 22 when the cat litter roller 2 rotates; when the feed assembly 3 is in operation, clean litter falls through the drum opening 22 into the litter drum 2.
In the invention, the motor 41 positively rotates to drive the cat litter roller 2 to rotate, and the waste material box cover 7 is opened and closed in the process; when the roller opening 22 is gradually close to the lower end of the housing 1, the sliding block 71 slides from the first sliding groove 25 to the second sliding groove 26, and the waste box cover 7 is gradually opened, so that the waste falls into the waste box 6; when the roller opening 22 is gradually far away from the lower end of the housing 1, the sliding block 71 slides from the second sliding groove 26 to the first sliding groove 25, and the waste material box cover 7 is gradually closed, so that the waste material box 6 is in a sealed state, and the residual peculiar smell in the waste material box can not be emitted to the outside.
The principle that the controller controls the operation of the stepping motor 41 according to the input information of the gravity sensing device 8 and the specific circuit structure are both easily realized in the prior art, and are not further described herein.
