[0035] It should be noted that through holes are respectively provided on the front and rear sides of the box body 1, and a rolling curtain door 7 is provided at each through hole.

[0036] In addition, a plurality of infrared sensors 8 are provided on the side of the urinal bed 3 of the box body 1. The infrared sensors 8, the sand swirling motor 21, the sand rubbing motor 34, the flipping motor 391 and the rotary electromagnet 55 are respectively electrically connected to a controller 9 in the electrical bin 19.

[0037] Specific implementation method and principle:

[0038] When the present utility model is actually applied, its initial state is as follows: the sand return box 4 is pre-filled with cat litter, the rolling curtain door 7 is lowered to close the access door on the front panel, the flipping motor 391 of the urinal bed 3 is reset so that the urinal bed 3 returns to the horizontal state, the sand rubbing motor 34 is reset so that the bottom plate of the urinal trough 31 and the grate holes on the rubbing grate 32 are misaligned and closed to prevent the cat litter laid on the urinal trough 31 from leaking downward. The sand swirling motor 21 of the sand swirling module 2 is started to lift the cat litter in the sand return box 4 to the sand dredging cylinder 24 through the sand swirling spiral 23 and the sand swirling cylinder 22 and then leak downward through the sand dredging grate 6 and evenly spread on the urinal trough 31 of the urinal bed 3. When the infrared sensor 8 detects that the laid cat litter reaches a certain thickness, the lifting of the cat litter is stopped. At the same time, the feces storage bag 1000 passes through the gap between the static pinch roller 52 and the moving pinch roller 53 and is placed in the feces collection drawer 5, and its opening is wound around the rolling ribs 51 of the feces collection drawer 5 and clamped by the spring clip 56. The rotary electromagnet 55 is powered off and under the action of the return spring therein, the upper opening of the feces storage bag 1000 is closed through the pinch roller swing arm 54. Then the rolling curtain door 7 is lifted upward to open the access door on the front panel, and the device is in a standby state.

[0039] When the cat urinates or defecates on the urination bed 3, the water in the urine or feces causes the cat litter particles to coagulate or be wrapped by the cat litter to form larger lumps. At this time, the infrared sensor 8 can sense the signal of the cat appearing on the urination bed 3. When the controller 9 determines that the cat has left the urination bed 3 according to the detection signal of the infrared sensor 8, then the rolling shutter door 7 is lowered to close the rolling shutter door to prevent the cat from interfering with and obstructing the machine. Then the controller controls the rotary electromagnet 55 to be energized and rotate, and the pinch roller swing arm 54 rotates the moving pinch roller 53 away from the static pinch roller 52, so that the upper opening of the feces storage bag 1000 is loosened. Next, the output shaft of the sand rubbing motor 34 drives the cam 35 to rotate a certain angle and reciprocate. By the pin shaft 36 moving in the strip-shaped groove of the cam 35, the rubbing grate 32 is driven to move left and right reciprocally so that the grate holes on the bottom plate of the urination trough 31 and the rubbing grate 32 are aligned, so that the recyclable cat litter that has not formed lumps in the urination bed 3 leaks into the lower sand return box 4. Then, the tilting drive module 39 operates, and the tilting motor 391 of the tilting drive module 39 jacks up the middle part of the urination bed 3 and rotates around the tilting shaft 33 to be tilted through the action of the tilting arm 392 and the roller 393 with the tilting guide rail 38, so that the lumped cat litter 1002 in the urination trough 31 rolls into the feces storage bag 1000 in the lower right. Then, the rotary electromagnet 55 is powered off, and under the action of its return spring, the upper opening of the feces storage bag 1000 is closed again through the pinch roller swing arm 54.

[0040] Then, the tilting motor 391 of the urination bed 3 resets to make the urination bed 3 return to the horizontal state, and the sand rubbing motor 34 resets to misalign the grate holes on the bottom plate of the urination trough 31 and the rubbing grate 32 to close to prevent the cat litter laid on the urination trough 31 from leaking downward.

[0041] Then, the sand rotating motor 21 of the sand rotating module 2 starts to lift the cat litter in the sand return box 4 to the sand dredging cylinder 24 through the sand rotating spiral 23 and the sand rotating cylinder 22, and leaks downward through the sand dredging grate 6 and is evenly spread on the urination bed 3. When the infrared sensor 8 detects that it reaches a certain thickness, the lifting of the cat litter stops. Then the rolling shutter door 7 is retracted to open the access door on the front panel, and the device is in the standby state again.

[0042] The above process is repeated until there is no remaining cat litter in the sand return box 4, and the sand rotating module 2 can no longer spread the cat litter on the urination bed 3 to the set thickness for the infrared sensor 8 to sense. At this time, the controller 9 issues a reminder signal, allowing the user to energize the rotary electromagnet 55 through the collection button of the controller to release and loosen the moving pinch roller 53 and take away the feces storage bag 1000. Then, the feces storage bag 1000 is replaced again, the sand return box 4 is refilled with cat litter, and the device is reset again.

[0043] The present utility model has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
