When the cat poop bin 3 continues to rotate, the cat litter temporarily stored in the sand storage space 312 can also flow back to the sand storage space 311 from the reflux port 333.

[0046] In the initial state, if Figure 3As shown, cat litter is stored in the litter storage space 311. For ease of understanding, it is taken as an example that the litter storage space 311 is located at the bottom of the accommodating chamber 31 and the litter storage space 312 is located at the top of the accommodating chamber 31. At this time, the cat can enter the accommodating chamber 31 from the entrance and exit and defecate on the cat litter. After the cat defecates and leaves, the gravity sensor of the cat litter box senses and drives the drum to rotate 180° in the counterclockwise direction with the feedback drive mechanism. During the rotation, the cat litter and the litter mass formed by the cat feces at the bottom of the accommodating chamber 31 will first slide to the screen 332. Through the filtration of the screen 332, the litter mass can flow along the screen 332 to the baffle 331 and be guided to the fecal outlet 32 ​​along the baffle 331, and the cat litter can pass through the screen 332 and enter the sand storage space 312 formed by the baffle 331 and the cavity wall of the accommodating chamber 31 for temporary storage. Figure 4 The driving mechanism then drives the drum to rotate 180° counterclockwise, and the cat litter in the litter storage space 312 flows along the cavity wall or baffle 331 of the accommodating cavity 31 to the connecting port, so that the cat litter flows back to the litter storage space 311 from the connecting port, that is, after one rotation, the cat litter and the cat feces litter group can be automatically separated, thereby improving the convenience of cleaning cat feces.

[0047] In addition, if Fig.11 and Fig.12 As shown, the cat stool bin 3 can also be a mounting seat, which is provided with a receiving slot 34 with an upward opening, the receiving slot 34 is a receiving chamber 31, and the notch of the receiving slot 34 is a stool outlet 32.

The rotation direction of the output shaft of the motor extends in the vertical direction. The second gear 412 is arranged on the first end 421. The first gear 411 is meshed with the second gear 412. The third gear 413 is arranged on the third end 431. The second gear 412 is meshed with the third gear 413. By meshing the second gear 412 arranged on the first end 421 with the third gear 413 arranged on the third end 431, the motor drives the first gear 411 to rotate, and the second gear 412 meshed with the first gear 411 can be rotated. The synchronous rotation of the second gear 412 can drive the third gear 413 to rotate, thereby realizing the driving of the first door body 42 and the second door body 43. The structure is simple, and only one motor is required to realize the rotation of the two door bodies, thereby reducing the occupied space of the driving member 41. Of course, in other embodiments, two motors may be directly provided to respectively drive the two door bodies to realize the first door body 42 and the second door body 43 to move closer to or farther away from each other.

[0058] Optionally, the cross section of the leakage port 11 is a rectangle, and the coincidence line of the first door body 42 and the second door body 43 coincides with a diagonal line of the rectangle. That is, when the first door body 42 and the second door body 43 are closed, they are symmetrically arranged about a diagonal line of the leakage port 11 to ensure the coordination of the structural installation of the first door body 42 and the second door body 43 and the synchronization of rotation. Of course, the cross section of the leakage port 11 can also be a circle, and the coincidence line of the first door body 42 and the second door body 43 coincides with a diameter of the circle. In addition, the cross-sectional shape of the leakage port 11 is not limited to a rectangle or a circle, and can also be other structures such as approximate rectangles, pentagons, hexagons, etc., and it is only necessary to ensure that the first door body 42 and the second door body 43 are symmetrically distributed to block the leakage port 11.

[0059] In other embodiments, Figure 2 and Fig.10 As shown, the first door body 42 is provided with a third stopper 424 protruding from one side of the second door body 43, and the second door body 43 is provided with a fourth stopper 434 protruding from one side of the first door body 42, and the third stopper 424 and the fourth stopper 434 are stacked in the vertical direction. By stacking the third stopper 424 and the fourth stopper 434, on the one hand, the area of ​​the contact surface between the first door body 42 and the second door body 43 can be increased, and on the other hand, the sand mass odor in the feces collecting trough 21 can be reduced from flowing directly out of the leakage port 11 from the gap between the door bodies in the vertical direction, so that the sealing performance of the sealing door 4 can be improved and the diffusion of the odor can be reduced.

[0060] Furthermore, two mounting blocks 6 are arranged at intervals along a second direction at the bottom of the support seat 1 (the second direction is one of the horizontal directions, and no specific direction example is given in this embodiment), and a clamping block is protruded on one side of the mounting blocks 6 adjacent to each other, and a clamping groove is formed between the clamping block and the support seat 1, and clamping blocks are protruded on both sides of the feces collecting box 2 along the second direction, and the two clamping blocks are respectively inserted into the two clamping grooves to realize the detachable connection between the feces collecting box 2 and the support seat 1.

[0061] Furthermore, the cat litter box also includes a sealing pad, and the feces collecting box 2 is provided with a sealing pad on the side facing the support base 1. By providing the sealing pad, the connection sealing between the feces collecting box 2 and the support base 1 is ensured, so that the diffusion of odor in the feces collecting tank 21 can be reduced.

[0062] In addition, the sealing door 4 can also be arranged on the feces collecting box 2 , and the sealing door 4 can block the notch of the feces collecting groove 21 .
