Specifically, the third driver 440 includes a sleeve 441 and a third motor 442, the sleeve 441 is sleeved at an output end of the third motor 442, and the sleeve 441 is circumferentially fixed with the output end of the third motor 442, the circumferentially fixed connection manner may be that a hexagonal bushing 443 is disposed at the output end of the third motor 442, the sleeve 441 is provided with a hexagonal clamping hole 4411 (as shown in fig. 10) facing the third motor 442, one end of the hexagonal bushing 443 is connected with the output end of the third motor 442, and the other end is clamped in the hexagonal clamping hole 4411; the sleeve 441 is fixedly connected with the separating part 200 in a mode that corresponding threaded holes are formed in the sleeve 441 and the separating part 200, and the sleeve 441 and the separating part 200 are connected and relatively fixed through threaded connecting pieces.

In one embodiment, a sensor (e.g., one or more of an infrared sensor, a photoelectric sensor, a laser sensor, an ultrasonic radar, a millimeter wave radar, etc.) may be disposed in the housing 421 to detect the status of the pet entering and exiting the pet litter box 10 and the defecation.

In one embodiment, the pet litter box 10 may further include a sterilizing function for sterilizing and disinfecting the pet litter in the litter box 100. Specifically, the pet toilet 100 can realize the disinfection function by arranging the ultraviolet disinfection lamp, the ultraviolet disinfection lamp is arranged above the litter box 100, for example, the ultraviolet disinfection lamp can be arranged on the cover plate 500 right above the litter box 100, or the ultraviolet disinfection lamp can be arranged on the side wall above the litter box 100, and the pet litter is disinfected and sterilized by the ultraviolet disinfection lamp. In other embodiments, the pet litter box 10 may be configured to sterilize and disinfect the pet litter by spraying disinfectant through an automatic spraying mechanism. In addition, the pet device 10 may further have a deodorizing function to remove the odor from the litter box 100, so as to prevent the odor from affecting pet excretion. Specifically, activated carbon may be disposed in the sand basin 100 to absorb the odor, and the odor may be removed by spraying an air freshener into the sand basin 100.

The pet toilet 10 using the driving device can drive the separating pieces 200 to move at the two opposite ends of the litter box 100 through the driving device 400, so that the separation of the pet sand and the pet sand blocks in the litter box 100 is realized, the automatic cleaning of the pet toilet 10 is completed, the automatic cleaning of the pet toilet 10 does not need to turn over the litter box, and therefore, the side wall of the pet toilet 10 is not easy to be stained with excrement. In addition, since the pet litter box 10 lifts the separating member 200 to the collecting opening 310 of the collecting device 300 in a lifting manner, the height of the collecting device 310 may be set to be higher than that of the litter box 100, which not only can increase the capacity of the collecting device 310, but also can reduce the odor in the collecting device 310 from flowing to the litter box 100 to affect pet excretion. In addition, because the driving arm 410 is rotatably connected with the driving source 420 and the separating element 200, the separating element 200 can move to any position of the litter box 100, the overall degree of freedom is high, and the device can adapt to various use scenes, for example, when a pet excretes, the separating element 200 and the driving arm 410 can be moved above the litter box 100, the use space of the pet in the litter box 100 is not occupied, and the influence of the separating element 200 and the driving arm 410 on the excretion of the pet is reduced; when the pet litter box 10 starts to automatically clean the pet litter block, the separating member 200 can clean all positions in the litter box 100, and the probability of the remaining pet litter block is low, so that the cleaning is thorough. After the pet sand block in the sand basin 100 is cleared, the driving device 400 can drive the separating element 200 to reciprocate in the sand basin 100, so as to flatly shovel the pet sand in the sand basin 100, and prevent the pet sand in the sand basin 100 from concentrating on a specific position and affecting the pet to drain.
