[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] like Figures 1 to 10 As shown, the cat litter box of this utility model embodiment includes a support base 1, a collection box 2, a cat feces chamber 3, and a sealing door 4. The support base 1 has a discharge port 11. The collection box 2 is detachably installed at the bottom of the support base 1 and has a collection trough 21 for accommodating cat feces, which is located below the discharge port 11. The cat feces chamber 3 is rotatably installed on the support base 1, and the rotation axis of the cat feces chamber 3 extends horizontally (the horizontal direction is the Y direction shown in the figure). The cat feces chamber 3 has a receiving cavity 31 and a discharge port 32, which connects the discharge port 11 and the receiving cavity 31. The cat feces chamber 3 has a screening component 33. When the cat feces chamber 3 rotates, the screening component 33 can screen out the cat feces in the receiving cavity 31 and pass through the discharge port 11 into the collection trough 21. The sealing door 4 is used to separate or connect the discharge port 11 and the opening of the collection trough 21.

[0042] Understandably, by rotating the cat litter box 3, the cat feces formed when the cat defecates in the receiving cavity 31 can be screened by the screening component 33, and collected into the collection trough 21 through the discharge port 11 via the discharge port 32, realizing automatic cleaning of cat feces, reducing manual cleaning and improving the user experience; by setting the sealing door 4, the discharge port 11 and the collection trough 21 can be effectively isolated, preventing the odor of cat feces evaporating in the collection trough 21 from entering the receiving cavity 31 through the discharge port 11, ensuring the freshness of the air in the receiving cavity 31 and improving the comfort of using the cat litter box.

[0043] Specifically, the litter box also includes a drive mechanism, which is mounted on the support base 1 and is connected to the cat litter compartment 3 for driving the cat litter compartment 3 to rotate. The cat litter compartment 3 also has an inlet / outlet for the cat to enter and exit on the side away from the drive mechanism. The inlet / outlet facilitates the cat's entry and exit from the receiving cavity 31.

[0044] Preferably, such as Figures 1 to 4 As shown, in some embodiments, the litter box also includes a protective shell 5, which covers the cat feces chamber 3 and is connected to the top of the support base 1 to prevent the pet cat or pet owner's fingers from getting caught in the gap between the cat feces chamber 3 and the support base 1, thereby improving the safety of using the litter box.

[0045] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the cat litter box 3 is a roller, with a receiving cavity 31 inside. The outer peripheral wall of the roller has a litter outlet 32. The roller rotates along a first direction (the first direction is the X direction shown in the diagram), i.e. Figure 3 and Figure 4 As shown in the diagram, X rotates counterclockwise. The screening assembly 33 includes a screen 332 with a baffle 331. The baffle 331 is disposed along the outer edge of the outlet 32 ​​and connected to the cavity wall of the receiving cavity 31 to divide the receiving cavity 31 into a litter storage space 311 and a litter trapping space 312. The litter storage space 311 is connected to the outlet 32 ​​and is used to store cat litter and for cats to defecate. The litter trapping space 312 is spaced apart from the outlet 32. The length of the baffle 331 extends along a first direction, and one end of the baffle 331 along the first direction is connected to the cavity wall of the receiving cavity 31. The spacer has a connecting opening that connects the litter storage space 311 and the litter storage space 312. A screen 332 is provided at the connecting opening. At least one return port 333 is provided at the end of the baffle 331 away from the connecting opening along the first direction. When the litter bin 3 rotates, the litter in the litter storage space 311 can pass through the screen 332 and enter the litter storage space 312 for temporary storage. The litter is screened by the screen 332 and flows along the baffle 331 to the litter outlet 32. As the litter bin 3 continues to rotate, the litter temporarily stored in the litter storage space 312 can also flow back to the litter storage space 311 from the return port 333.

[0046] In the initial state, such asFigure 3 As shown, cat litter is stored in the litter storage space 311. For ease of understanding, let's assume that in this state, the litter storage space 311 is located at the bottom of the receiving cavity 31, and the litter trapping space 312 is located at the top of the receiving cavity 31. At this time, the cat can enter the receiving cavity 31 through the inlet / outlet and defecate on the litter. After the cat leaves, the gravity sensor of the litter box senses and drives the roller to rotate 180° counterclockwise via a feedback drive mechanism. During the rotation, the litter and feces at the bottom of the receiving cavity 31 will first slide to the screen 332. Through the filtration of the screen 332, the litter can flow along the screen 332 to the baffle 331 and be guided out of the feces outlet 32. The cat litter can then pass through the screen 332 and enter the litter trapping space 312 formed by the gap between the baffle 331 and the cavity wall of the receiving cavity 31 for temporary storage. Figure 4 As shown. The drive mechanism then drives the roller to rotate 180° counterclockwise, and the cat litter in the litter storage space 312 will flow along the cavity wall of the receiving cavity 31 or the baffle 331 to the connecting port, so that the cat litter flows back from the connecting port to the litter storage space 311. That is, one rotation can realize the automatic separation of cat litter and cat feces litter clumps, improving the convenience of cat feces cleaning.

[0047] In addition, such as Figure 11 and Figure 12 As shown, the cat litter box 3 can also be a mounting base. The mounting base is provided with an upward-facing receiving groove 34, which is a receiving cavity 31. The opening of the receiving groove 34 is a feces outlet 32. The screening component 33 includes a baffle 331 and a screen 332. The baffle 331 includes a first stop 3311 and a second stop 3312 arranged at an angle. The first stop 3311 divides the receiving groove 34 into a litter storage trough 341 and a litter trap 342. The litter storage trough 341 is used to store cat litter and for cats to defecate. The first stop 3311 and the bottom of the receiving groove 34 form a communication opening. A screen 332 is provided at the communication opening. The second stop 3312 is used to block the opening of the litter trap 342. The mounting base can rotate a specified angle in a third direction (the third direction is...). Figure 12 (As shown in direction A), the cat litter in the litter storage tank 341 can pass through the screen 332 and enter the litter storage tank 342 for temporary storage. The cat feces are sieved by the screen 332 and flow along the first stop 3311 to the feces outlet 32. The mounting base rotates in the fourth direction (the fourth direction is...). Figure 12 (As shown in direction B), the cat litter temporarily stored in the litter trough 342 can flow back to the litter storage trough 341 from the screen 332, wherein the third direction is opposite to the fourth direction.

[0048] Initially, the cat litter is stored in the litter box 341. The cat can then enter the litter box 341 through the opening of the receiving trough 34 to defecate. After the cat leaves, the litter box's gravity sensor senses the pressure and triggers a feedback drive mechanism to rotate the mounting base 90°–180° in a third direction. During this rotation, the litter and feces at the bottom of the litter box 341 slide to the screen 332. Through the filtration of the screen 332, the litter passes through the screen 332 and enters the screen 332, the first stop 3311 of the baffle 331, and the second stop 331 of the baffle 331. 2. The litter is temporarily stored in the litter trough 342 formed by the enclosure of the receiving trough 34 and the litter clumps on the screen 332 or the first stop 3311, while the litter clumps fall from the outlet 32 ​​to the discharge port 11 of the support base 1. Then the mounting base rotates back to the initial position in the fourth direction, and the cat litter in the litter trough 342 will flow along the wall of the receiving trough 34 to the holes of the screen 332 due to its own gravity, so that the cat litter flows back to the litter storage trough 341. That is, by rotating the mounting base at a specified angle and resetting to the initial position, the cat litter and cat feces clumps can be automatically separated, improving the convenience of cat feces cleaning.

[0049] In some embodiments, such as Figures 2 to 10 As shown, the sealing door 4 is installed on the support base 1, and the sealing door 4 can block the leakage port 11. The collection box 2 is connected to the support base 1, that is, the opening of the collection trough 21 is connected to the receiving cavity 31 or the outside only through the leakage port 11. Therefore, by blocking the leakage port 11, the opening of the collection trough 21 can be blocked, thereby reducing the diffusion of the odor of the sand clumps in the collection trough 21.

[0050] In this embodiment, as Figure 6 and Figure 7 As shown, the support base 1 consists of a first connecting plate 13 and a second connecting plate 14 spaced apart in the vertical direction (vertical direction is the Z direction shown in the figure). A first opening 111 is provided through the first connecting plate 13 in the vertical direction, and a second opening 112 is provided on the second connecting plate 14 corresponding to the first opening 111. The first opening 111 and the second opening 112 form a discharge port 11, and the first connecting plate 13 and the second connecting plate 14 are connected to form a closed fixed cavity. The waste collection box 2 is connected to the bottom of the second connecting plate 14. The sealing door 4 is set in the fixed cavity and at the bottom of the first connecting plate 13. The waste outlet 32 ​​can communicate with the first opening 111. By sealing the first opening 111 through the sealing door 4, the fixed cavity and the waste collection tank 21 are sealed. By setting the sealing door 4 in the fixed cavity, the movement of the cat waste tank 3 and the waste collection box 2 is reduced, making the arrangement between the cat waste tank 3, the support base 1 and the waste collection box 2 more reasonable, and reducing interference between moving structures in a compact structure.

[0051] Of course, the sealing door 4 can also be set inside the fixed cavity and located on top of the second connecting plate 14, thereby sealing the collection trough 21 by blocking the second opening 112. Alternatively, the sealing door 4 can be set on the collection box 2, and the sealing door 4 can block the opening of the collection trough 21, that is, the sealing door 4 can be set independently inside the collection box 2, and the opening of its own collection trough 21 can be blocked by closing the sealing door 4.

[0052] Furthermore, such as Figure 8 As shown, the sealing door 4 is mounted on the support base 1. The sealing door 4 includes a driving member 41, a first door body 42, and a second door body 43. The driving member 41 is mounted on the mounting portion 12 of the support base 1. The first door body 42 has a first end 421 rotatably connected to the mounting portion 12 and a second end 422 away from the mounting portion 12. The second door body 43 has a third end 431 rotatably connected to the mounting portion 12 and a fourth end 432 away from the mounting portion 12. The rotation axes of the first end 421 and the third end 431 extend vertically. The driving member 41 drives the first door body 42 and the second door body 43 to rotate, so that the second end 422 and the fourth end 432 move away from or closer to each other, thereby blocking or opening the leakage port 11. The sealing door 4 has a simple structure. The first door body 42 and the second door body 43 are opened synchronously by the driving member 41, thereby opening the leakage port 11, allowing the outlet 32 ​​to communicate with the collection tank 21 through the leakage port 11. By combining the first door body 42 and the second door body 43, the opening and closing speed of the sealing door 4 can be effectively improved compared to the structure of the entire door body moving horizontally. Furthermore, the rotational arrangement of the first door body 42 and the second door body 43 occupies less space overall compared to the horizontal movement of the door body, resulting in a more reasonable layout.

[0053] Preferably, such as Figure 8 and Figure 9 As shown, the sealing door 4 also includes a first guide rail 44 and a second guide rail 45 disposed on the support base 1. The second end 422 is slidably connected to the first guide rail 44, and the fourth end 432 is slidably connected to the second guide rail 45. By setting the first guide rail 44 and the second guide rail 45, on the one hand, the first guide rail 44 can support the second end 422, and the second guide rail 45 can support the fourth end 432, reducing the possibility of the first door body 42 and the second door body 43 sagging at the end away from the mounting part 12 due to their own weight, ensuring the structural stability of the first door body 42 and the second door body 43, thereby ensuring the sealing performance of the leakage port 11; on the other hand, it can also improve the movement guidance and stability of the second end 422 and the fourth end 432.

[0054] Optionally, a first groove 441 is provided on the first guide rail 44, the length of the first groove 441 extends along the rotation direction of the second end 422, and a first guide part 423 is provided at the bottom of the second end 422, which is inserted into the first groove 441; a second groove 451 is provided on the second guide rail 45, the length of the second groove 451 extends along the rotation direction of the fourth end 432, and a second guide part 433 is provided at the bottom of the fourth end 432, which is inserted into the second groove 451. That is, the top surface of the first guide rail 44 supports the second end 422, and the top surface of the second guide rail 45 supports the fourth end 432. The structure of the guide part and the guide groove is simple and convenient for production and disassembly.

[0055] Of course, when the first slide groove 441 is disposed on the side of the first guide rail 44 arranged in the horizontal direction, the first guide part 423 is disposed on the side of the second end 422. That is, the groove wall of the first slide groove 441 not only guides and limits the first guide part 423, but also supports the first guide part 423. Similarly, when the second slide groove 451 is disposed on the side of the second guide rail 45 arranged in the horizontal direction, the second guide part 433 is disposed on the side of the fourth end 432. That is, the groove wall of the second slide groove 451 not only guides and limits the second guide part 433, but also supports the second guide part 433.

[0056] In addition, in other embodiments, an integral third guide rail can be provided, which is disposed on the support base 1, and the second end 422 and the fourth end 432 are slidably connected to the third guide rail.

[0057] Furthermore, the driving component 41 includes a motor and a first gear 411. The motor is mounted on the mounting part 12, and the first gear 411 is mounted on the output shaft of the motor. The rotation direction of the output shaft of the motor extends vertically. A second gear 412 is mounted on the first end 421, and the first gear 411 meshes with the second gear 412. A third gear 413 is mounted on the third end 431, and the second gear 412 meshes with the third gear 413. By the meshing of the second gear 412 on the first end 421 and the third gear 413 on the third end 431, the motor drives the first gear 411 to rotate, which in turn causes the second gear 412, which meshes with the first gear 411, to rotate. The synchronous rotation of the second gear 412 drives the third gear 413 to rotate, thereby realizing the driving of the first door 42 and the second door 43. The structure is simple, requiring only one motor to realize the rotation of the two doors, reducing the space occupied by the driving component 41. Of course, in other embodiments, two motors can be directly set to drive the two doors respectively to achieve the mutual approach or distance between the first door 42 and the second door 43.

[0058] Optionally, the cross-section of the discharge port 11 is rectangular, and the coincidence line of the first gate 42 and the second gate 43 coincides with one diagonal of the rectangle. That is, when the first gate 42 and the second gate 43 are closed, they are symmetrically arranged about one diagonal of the discharge port 11, ensuring the coordination of the installation of the first gate 42 and the second gate 43 and the synchronicity of their rotation. Of course, the cross-section of the discharge port 11 can also be circular, and the coincidence line of the first gate 42 and the second gate 43 coincides with one diameter of the circle. In addition, the cross-sectional shape of the discharge port 11 is not limited to rectangular or circular, and can also be other approximately rectangular, pentagonal, hexagonal, etc., as long as the first gate 42 and the second gate 43 are symmetrically distributed to seal the discharge port 11.

[0059] In other embodiments, such as Figure 2 and Figure 10 As shown, a third stop 424 protrudes from the side of the first door 42 facing the second door 43, and a fourth stop 434 protrudes from the side of the second door 43 facing the first door 42. The third stop 424 and the fourth stop 434 are stacked vertically. This stacking of the third stop 424 and the fourth stop 434 increases the contact area between the first door 42 and the second door 43, and reduces the amount of odor from the sand clumps in the collection trough 21 that can flow directly out of the drain outlet 11 through the gaps between the doors, thus improving the sealing performance of the sealing door 4 and reducing odor diffusion.

[0060] Furthermore, two mounting blocks 6 are spaced apart at the bottom of the support base 1 along the second direction (the second direction is one of the horizontal directions, and no specific direction is given in this embodiment). The mounting blocks 6 are provided with a locking block on one side adjacent to each other. The locking block and the support base 1 are spaced apart to form a locking groove. The toilet box 2 is provided with locking blocks on both sides along the second direction. The two locking blocks are respectively inserted into the two locking grooves to realize the detachable connection between the toilet box 2 and the support base 1.

[0061] Furthermore, the litter box also includes a sealing gasket, with the waste collection box 2 having a sealing gasket on the side facing the support base 1. The sealing gasket ensures a tight seal between the waste collection box 2 and the support base 1, thereby reducing the spread of odor within the waste collection trough 21. Additionally, a sealing door 4 can be installed on the waste collection box 2, which can seal the opening of the waste collection trough 21.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
