[0047] Combination Figures 6 to 9 As shown, the basin 10 has a receiving cavity 11 for holding cat litter. One end of the basin 10 is provided with a basin opening 12, which is connected to one end of the receiving cavity 11. The lower inner wall of the basin opening 12 is provided with a first groove 121 and a second groove 122, both of which are connected to one end of the receiving cavity 11.

[0048] The litter bin 20 is used to collect cat litter clumps. The length of the litter bin 20 is the same as the width of the basin 10. The litter bin 20 is located at one end of the basin 10. In this embodiment, the litter bin 20 is detachably located at one end of the basin 10, making it easy to assemble and disassemble, thus facilitating the owner to empty the cat litter clumps collected in the litter bin 20 and to clean the litter bin 20. The top of the litter bin 20 has a litter bin opening 21 and a clearance groove 25. Both the litter bin opening 21 and the clearance groove 25 are connected to the interior of the litter bin 20. The side of the litter bin 20 closest to the basin 10 has a clearance opening 26. The clearance groove 25 corresponds to the litter bin opening 21 and is located between the litter bin opening 21 and the clearance opening 26. The clearance groove 25 and the litter bin opening 21 are connected by a connecting groove 251, which is connected to the interior of the litter bin 20. The clearance opening 26 corresponds to the clearance groove 25 and the basin opening 12, respectively, and communicates with both. The lower inner wall of the clearance opening 26 is located below the top of the garbage bin 20 and above the bottom of the clearance groove 25, and is flush with the lower inner wall of the basin opening 12. The lower inner wall of the clearance opening 26 is provided with a third groove 261 corresponding to the first groove 121 and a fourth groove 262 corresponding to the second groove 122.

The bottom of the clearance groove 25 and the inner wall of the clearance groove 25 near the garbage bin opening 21 are connected by an arc surface 252, resulting in an aesthetically pleasing appearance.

[0049] The trash can 20 is detachably mounted at one end of the basin 10. Specifically, at one end of the basin 10, below the basin opening 12, there is an annular basin connecting part 13. Inside the basin connecting part 13, there is a basin mounting part 14. One end of the basin mounting part 14 is provided with an insertion hole 141. On the side of the trash can 20 near the basin 10, there is a trash can connecting part 24 corresponding to the basin connecting part 13. One end of the trash can connecting part 24 is provided with a circular trash can mounting part 241. One end of the trash can mounting part 241 is provided with a connector 242. The trash can mounting part 241 is inserted into the basin connecting part 13, and the connector 242 is inserted into the insertion hole 141. By pulling out the garbage bin mounting part 241 and the connector 242 from the basin body connecting part 13 and the socket 141, the garbage bin 20 can be removed from the basin body 10. In this embodiment, there are two basin body connecting parts 13, which are spaced apart along the width direction of the basin body 10. The number of garbage bin connecting parts 24 corresponds to the number of basin connecting parts 13, which is also two. It can be understood that the number of basin connecting parts 13 and garbage bin connecting parts 24 can be set according to the actual situation.

[0050] The trash can opening 21 is provided with a lid 22, which can be rotated relative to the trash can 20 in a direction away from or towards the basin 10 to open or close the trash can opening 21.

[0051] In this embodiment, a pivot 221 is provided between the inner walls of both ends of the garbage bin opening 21. The bin cover 22 is rotatably fitted onto the pivot 221. The pivot 221 is located between the center of the bin cover 22 and the end of the bin cover 22 away from the basin 10. The bin cover 22 can rotate around the pivot 221, that is, with the pivot 221 as the fulcrum, relative to the garbage bin 20 in a direction away from or towards the basin 10. The end of the bin cover 22 near the basin 10 is located in the connecting groove 251 and rests on the lower inner wall of the connecting groove 251, such as... Figure 3 As shown.

[0052] In this embodiment, two mounting holes are provided on the inner walls of both ends of the garbage bin opening 21, and the two ends of the rotating shaft 221 are respectively set in the two mounting holes.

[0053] An extension 222 is formed at one end of the lid 22 near the basin 10. The extension 222 is located within the clearance groove 25 and the clearance opening 26, and between the third groove 261 and the fourth groove 262. The end of the extension 222 furthest from the lid 22 and the bottom end of the extension 222 are connected by an arc surface 2221. A space 263 exists between the arc surface 2221 and the lower inner wall of the clearance opening 26. Figure 3 As shown, the width of the space gradually decreases in the direction away from the litter box 10. The lid 22 is provided to prevent the spread of cat litter odor.

[0054] A baffle 23 is formed at the top of the trash can 20, on the side away from the basin 10. When the litter clumps are poured into the trash can 20 through the opening 21 using the cleaning rake 40, the baffle 23 prevents the litter clumps from falling outside the trash can 20. The baffle 23 has a through hole 231, which allows for easy insertion of a finger, making it convenient to carry the trash can 20 and use it.

[0055] Combination Figures 10 to 15 As shown, the cleaning device is mounted on the basin 10. The cleaning device is used to scoop up litter clumps from the receiving cavity 11, rotate the lid 22 away from the basin 10 to open the trash can opening 21, and simultaneously pour the scooped litter clumps into the trash can 20 through the opening 21, and to level the litter in the receiving cavity 11. The cleaning device includes a cleaning drive mechanism 30 and a cleaning rake 40.

[0056] The cleaning drive mechanism 30 is mounted on the basin 10. The cleaning rake 40 is approximately L-shaped and has a mesh structure. The cleaning rake 40 is located at one end of the receiving cavity 11. One end of the cleaning rake 40 is close to the bottom of the receiving cavity 11, and the other end of the cleaning rake 40 is inclined upward towards the garbage bin 20 and is equipped with a connecting rod 41. The connecting rod 41 is connected to the cleaning drive mechanism 30. The connecting rod 41 corresponds to the space 263, as shown... Figure 3 As shown. The cleaning drive mechanism 30 is used to drive the connecting rod 41 to move closer to or further away from the trash can 20 and to drive the connecting rod to rotate, thereby driving the cleaning rake 40 to move closer to or further away from the trash can 20 and to rotate the cleaning rake 40 about the axis of the connecting rod 41 in a direction closer to or further away from the trash can 20. The cleaning rake 40 is used to scoop up litter clumps in the receiving cavity 11, to pour litter clumps into the trash can 20 through the trash can opening 21 while the trash can opening 21 is open, and to smooth out the litter in the receiving cavity 11.

[0057] like Figure 3 and Figure 13 As shown, the cleaning rake 40 has two opposing pushers 42 on the side away from the garbage bin 20. The two pushers 42 are close to the two sides of the cleaning rake 40 and can move synchronously with the cleaning rake 40. The two pushers 42 are used to drive the extension 222 to rotate away from the basin 10, thereby driving the bin cover 22 to rotate away from the basin 10 to open the garbage bin opening 21.

[0058] Specifically, the cleaning drive mechanism 30 includes a housing 31, a first translation drive assembly 32, a second translation drive assembly 33, a rotation drive assembly 34, and a support assembly 35.

[0059] The outer casing 31 is U-shaped and is detachably mounted on the top of the basin 10 for easy assembly and disassembly. The receiving cavity 11 is located inside the U-shaped cavity 314 of the outer casing 31. Specifically, as shown... Figure 3 and Figure 10 As shown, the bottom of the outer shell 31 is provided with a U-shaped slot 316, and the top of the basin 10 is formed with a U-shaped locking part 15 corresponding to the slot 316. The cross-sectional shape of the locking part 15 is L-shaped, and the locking part 15 engages with the slot 316.

[0060] The outer casing 31 has a U-shaped inner cavity 313. The first translation drive assembly 32 and the second translation drive assembly 33 are both disposed within the inner cavity 313 of the outer casing 31. The rotation drive assembly 34 and the support assembly 35 are disposed opposite to each other, and are both located at one end of the receiving cavity 11 and close to the inner walls of the two sides of the receiving cavity 11, respectively. The rotation drive assembly 34 extends partially into the basin opening 12 and the first groove 121, and the support assembly 35 extends partially into the basin opening 12 and the second groove 122. The support component 35 is connected to the first translation drive component 32, and the rotation drive component 34 is connected to the second translation drive component 33. The first translation drive component 32 is used to drive the support component 35 to move towards or away from the garbage bin 20. The second translation drive component 33 is used to synchronously drive the rotation drive component 34 to move towards or away from the garbage bin 20. During the movement of the rotation drive component 34 towards the garbage bin 20, the provided basin opening 12, first groove 121, avoidance opening 26, third groove 261, and avoidance slot 25 can avoid the rotation drive component 34. During the movement of the support component 35 towards the garbage bin 20, the provided basin opening 12, second groove 122, avoidance opening 26, fourth groove 262, and avoidance slot 25 can avoid the support component 35. The cleaning rake 40 and the connecting rod 41 are located between the rotary drive assembly 34 and the support assembly 35. One end of the connecting rod 41 is detachably connected to the support assembly 35, and the other end is detachably connected to the rotary drive assembly 34. The movement of the support assembly 35 and the rotary drive assembly 34 can drive the connecting rod 41 to move closer to or away from the garbage bin 20, thereby driving the cleaning rake 40 to move closer to or away from the garbage bin 20. The rotary drive assembly 34 is used to drive the connecting rod 41 to rotate, thereby driving the cleaning rake 40 to rotate closer to or away from the garbage bin 20. During the movement and rotation of the connecting rod 41 and the cleaning rake 40 towards the garbage bin 20, the basin opening 12, the avoidance opening 26, and the avoidance groove 25 can provide avoidance for the connecting rod 41, the cleaning rake 40, and the two pushing parts 42. The support component 35 supports the connecting rod 41, thereby supporting the cleaning rake 40 and the two pushers 42, ensuring the smooth movement and rotation of the cleaning rake 40 and the two pushers 42.

[0061] The first translation drive assembly 32 and the second translation drive assembly 33 are centrally symmetrical about the U-shaped cavity 314. Both the first translation drive assembly 32 and the second translation drive assembly 33 include a translation motor 321, a lead screw 322, and a nut seat 323. The translation motor 321 is disposed within the inner cavity 313. In this embodiment, the translation motor 321 is mounted on the bottom of the inner cavity 313 via a motor mount. The U-shaped cavity 314 is located between the garbage bin 20 and the translation motor 321. The lead screw 322 of the first translation drive assembly 32 and the lead screw 322 of the second translation drive assembly 33 are respectively located on both sides of the U-shaped cavity 314. The lead screw 322 is rotatably disposed within the inner cavity 313. One end of the lead screw 322 is connected to the output end of the translation motor 321 via a bevel gear structure 325, and the other end of the lead screw 322 is close to the garbage bin 20. The nut seat 323 is threadedly engaged with the lead screw 322. The support assembly 35 is connected to the nut seat 323 of the first translation drive assembly 32, and the rotary drive assembly 34 is connected to the nut seat 323 of the second translation drive assembly 33. The translation motor 321 drives the lead screw 322 to rotate via the bevel gear structure 325, thereby causing the nut seat 323 to move towards or away from the garbage bin 20. The nut seat 323 of the first translation drive assembly 32 can drive the support assembly 35 to move towards or away from the garbage bin 20, and the nut seat 323 of the second translation drive assembly 33 can drive the rotary drive assembly 34 to move synchronously towards or away from the garbage bin 20.

[0062] The lead screw 322 is rotatably disposed within the inner cavity 313. Specifically, two mounting seats 324 corresponding to the lead screw 322 are provided on the bottom of the inner cavity 313. The two mounting seats 324 are spaced apart along the length of the basin 10. One mounting seat 324 is close to the translation motor 321, and the other mounting seat 324 is close to the garbage bin 20. One end of the lead screw 322 passes through the through hole of one of the mounting seats 324 and is connected to the output end of the translation motor 321 through the bevel gear structure 325. The other end of the lead screw 322 is rotatably disposed within the through hole of the other mounting seat 324. A lead screw bearing is provided within the through hole and is sleeved on the lead screw 322 to provide support for the rotation of the lead screw 322.

[0063] The bevel gear structure 325 includes a first bevel gear 3251 and a second bevel gear 3252. The first bevel gear 3251 is sleeved on the output end of the translation motor 321, and the second bevel gear 3252 is sleeved on one end of the lead screw 322 and meshes with the first bevel gear 3251. The translation motor 321 drives the first bevel gear 3251 to rotate, which in turn drives the second bevel gear 3252 to rotate, and in turn drives the lead screw 322 to rotate.

[0064] Furthermore, both the first translation drive assembly 32 and the second translation drive assembly 33 include a guide rod 326. The guide rod 326 is disposed within the inner cavity 313 and located on the side of the lead screw 322 away from the U-shaped cavity 314. Specifically, the guide rod 326 is located between two mounting seats 324, one of which has a first guide rod hole and the other has a second guide rod hole. One end of the guide rod 326 is disposed in the first guide rod hole, and the other end is disposed in the second guide rod hole. The guide rod 326 and the lead screw 322 are arranged in parallel, and the nut seat 323 is slidably sleeved on the guide rod 326. In this embodiment, the nut seat 323 has a screw hole 3231 and a nut through hole 3232. The nut seat 323 is sleeved on the lead screw 322 through the screw hole 3231, and the screw hole 3231 is threadedly engaged with the lead screw 322. The nut seat 323 is slidably sleeved on the guide rod 326 through the nut through hole 3232. The rotation of the lead screw 322 can drive the nut seat 323 to move along the guide rod 326. The guide rod 326 provides guidance for the movement of the nut seat 323, thereby improving the smoothness of the movement of the nut seat 323, and further improving the smoothness of the movement of the support assembly 35 and the rotary drive assembly 34.

[0065] The support assembly 35 includes a support shell 351, a damping bearing 352, and a first connector 353. The support shell 351 partially extends into the basin opening 12 and the second groove 122. A first mounting member 3511 is provided at the top of the support shell 351. One end of the first mounting member 3511 passes through a first strip-shaped hole (not shown in the figure) at the bottom of the outer shell 31 and extends into the inner cavity 313, connecting to the nut seat 323 of the first translation drive assembly 32. The first connector 353 is disposed within the support shell 351, with one end extending from the side of the support shell 351 closest to the rotation drive assembly 34. The side of the support shell 351 closest to the rotation drive assembly 34 has a support shell hole for one end of the first connector 353 to extend out. One end of the connecting rod 41 is detachably connected to one end of the first connector 353. The damping bearing 352 is disposed within the support shell 351 and sleeved on the first connector 353. The damping bearing 352 provides support for the rotation of the first connecting member 353, and in turn, supports the rotation of the connecting rod 41. This improves the stability of the rotation of the connecting rod 41, the cleaning rake 40, and the two pushing members 42, ensuring that excessive resistance is not generated during rotation. Furthermore, when a pet cat or external force presses on the cleaning rake 40, the damping bearing 352 generates a preload, preventing damage to the cleaning rake 40 and the rotary drive assembly 34. The damping bearing 352 is made of plastic.

[0066] In this embodiment, a mounting plate 3521 is provided inside the support shell 351. The mounting plate 3521 is sleeved on the damping bearing 352. A mounting post 3512 is provided on the inner wall of the support shell 351 on the side away from the rotary drive assembly 34. The mounting plate 3521 has mounting holes corresponding to the mounting posts 3512. Fasteners such as screws are installed in the mounting holes and mounting posts 3512. The number of mounting posts 3512 and mounting holes can be set according to actual conditions. The mounting plate 3521 provides mounting support for the damping bearing 352.

[0067] The rotary drive assembly 34 includes a rotary housing 341, a rotary motor 342, a transmission gear structure 343, and a second connecting member 344. The rotary housing 341 extends into the basin opening 12 and the first groove 121. The top of the rotary housing 341 is provided with a second mounting member 3411. One end of the second mounting member 3411 passes through the second strip hole 315 at the bottom of the outer shell 31 and extends into the inner cavity 313, and is connected to the nut seat 323 of the second translation drive assembly 33. The length direction of the second strip hole 315 is the same as the length direction of the basin 10. The first strip hole and the second strip hole 315 are symmetrical about the center of the U-shaped cavity 314. The rotary motor 342, the transmission gear structure 343, and the second connecting member 344 are all housed inside the rotary housing 341. The output end of the rotary motor 342 is connected to the second connecting member 344 through the transmission gear structure 343. One end of the second connecting member 344 extends from the side of the rotary housing 341 near the support component 35. The side of the rotary housing 341 near the support component 35 has a rotary housing hole for one end of the second connecting member 344 to extend out. The other end of the connecting rod 41 is detachably connected to one end of the second connecting member 344. The rotary motor 342 drives the second connecting member 344 to rotate through the transmission gear structure 343, thereby driving the connecting rod 41 to rotate, which in turn drives the cleaning rake 40 to rotate toward or away from the garbage bin 20.

[0068] The movement of the nut seat 323 of the first translation drive assembly 32 can drive the support shell 351 to move closer to or away from the garbage bin 20 through the first mounting member 3511, thereby driving the first connector 353 and the damping bearing 352 to move closer to or away from the garbage bin 20. The movement of the nut seat 323 of the second translation drive assembly 33 can drive the rotating shell 341 to move closer to or away from the garbage bin 20 simultaneously through the second mounting member 3411, thereby driving the rotary motor 342, the transmission gear structure 343, and the second connector 344 to move closer to or away from the garbage bin 20. The first connector 353 and the second connector 344 can then drive the connecting rod 41 to move.

[0069] One end of the connecting rod 41 is detachably connected to one end of the first connecting member 353, and the other end of the connecting rod 41 is detachably connected to one end of the second connecting member 344. This facilitates the disassembly and assembly of the connecting rod 41, thereby facilitating the disassembly and assembly of the cleaning rake 40. This also facilitates cleaning and replacement of the cleaning rake 40. Specifically, one end of the first connecting member 353 has a first insertion hole 3531, into which one end of the connecting rod 41 is inserted. The outer wall of one end of the first connecting member 353 has two first mounting holes, which are arranged opposite to each other and communicate with the first insertion hole 3531. A first fastener 354 is installed in each of the first mounting holes, and the tail end of the first fastener 354 abuts against one end of the connecting rod 41 to fix the first connecting member 353 and one end of the connecting rod 41 together. The first fastener 354 is a headless screw. One end of the second connector 344 has a second insertion hole 3441, and the other end of the connecting rod 41 is inserted into the second insertion hole 3441. The outer wall of one end of the second connector 344 has two second mounting holes, which are arranged opposite to each other and communicate with the second insertion hole 3441. A second fastener 345 is installed in each of the second mounting holes, and the tail end of the second fastener 345 abuts against the other end of the connecting rod 41 to fix the second connector 344 and the other end of the connecting rod 41 together. The second fastener 345 is a headless screw. The number of first and second mounting holes can also be other, such as three or four, depending on the actual situation. Using headless screws makes installation convenient, disassembly quick, and improves the appearance of the litter box.

[0070] When actually removing the cleaning rake 40 from the support assembly 35 and the rotary drive assembly 34, first remove the first fastener 354 and the second fastener 345. Then, pull one end and the other end of the connecting rod 41 out of the first insertion hole 3531 and the second insertion hole 3441, respectively. In this way, the cleaning rake 40 is removed from the support assembly 35 and the rotary drive assembly 34. When actually connecting the cleaning rake 40 to the support assembly 35 and the rotary drive assembly 34, first insert one end and the other end of the connecting rod 41 into the first insertion hole 3531 and the second insertion hole 3441, respectively. Then, install the first fastener 354 in the corresponding first mounting hole and make the tail end of the first fastener 354 abut against one end of the connecting rod 41. Similarly, install the second fastener 345 in the corresponding second mounting hole and make the tail end of the second fastener 345 abut against the other end of the connecting rod 41.

[0071] The transmission gear structure 343 serves to reduce speed and includes a worm gear 3431, a first double gear 3432, a second double gear 3433, a third double gear 3434, a fourth double gear 3435, and a drive gear 3436. The worm gear 3431 is mounted on the output end of the rotary motor 342. The first double gear 3432 meshes with the worm gear 3431, the second double gear 3433 meshes with the first double gear 3432, the third double gear 3434 meshes with the second double gear 3433, and the fourth double gear 3435 meshes with the third double gear 3434. The drive gear 3436 meshes with the fourth double gear 3435 and is mounted on the second connecting member 344. A rotary motor 342 drives the worm gear 3431 to rotate, which in turn drives the first double gear 3432 to rotate, which in turn drives the second double gear 3433 to rotate. The rotation of the second double gear 3433 drives the third double gear 3434 to rotate, which in turn drives the fourth double gear 3435 to rotate, which in turn drives the drive gear 3436 to rotate. The rotation of the drive gear 3436 drives the second connecting member 344 to rotate, which in turn drives the connecting rod 41 to rotate. The teeth of the worm gear 3431, the first double gear 3432, the second double gear 3433, the third double gear 3434, the fourth double gear 3435, and the drive gear 3436 are not shown in the accompanying drawings. The worm gear 3431 enables a self-locking function, preventing the risk of the cleaning rake 40 falling during power outages when the rake 40 moves or rotates. The worm gear 3431, the first double gear 3432, the second double gear 3433, the third double gear 3434, the fourth double gear 3435, and the drive gear 3436 can form a multi-stage gear transmission, thereby achieving a high transmission ratio and transmission accuracy.

[0072] In this embodiment, the rotary motor 342 is mounted on the inner wall of the rotating shell 341 on the side away from the support component 35 via a motor mount. The first double gear 3432, the second double gear 3433, the third double gear 3434, and the fourth double gear 3435 are all existing structures, each including a gear shaft and a large gear and a small gear sleeved on the gear shaft. The small gear and the large gear are connected to each other. The inner wall of the rotating shell 341 on the side near the support component 35 is provided with a first hole corresponding to the gear shaft, and the inner wall of the rotating shell 341 on the side away from the support component 35 is provided with a second hole corresponding to the gear shaft. One end of the gear shaft is rotatably disposed in the first hole, and the other end of the gear shaft is rotatably disposed in the second hole. The large gear of the first double gear 3432 meshes with the worm 3431; the small gear of the first double gear 3432 meshes with the large gear of the second double gear 3433; the small gear of the second double gear 3433 meshes with the large gear of the third double gear 3434; the small gear of the third double gear 3434 meshes with the large gear of the fourth double gear 3435; and the small gear of the fourth double gear 3435 meshes with the drive gear 3436.

[0073] In this embodiment, the outer shell 31 includes a lower shell 311 and an upper shell 312 that are interlocked. The bottom end of the lower shell 311 is provided with the aforementioned U-shaped groove 316, a first strip-shaped hole, and a second strip-shaped hole 315. The upper shell 312 and the lower shell 311 enclose each other to form an inner cavity 313 of the outer shell 31. The top end of the lower shell 311 forms the bottom of the inner cavity 313. The support shell 351 includes two interlocked support half-shells 351a. The two support half-shells 351a enclose each other to form the interior of the support shell 351. The bottom of one support half-shell 351a forms the inner wall of the support shell 351 on the side away from the rotary drive assembly 34, and the bottom of the other support half-shell 351a forms the inner wall of the support shell 351 on the side closer to the rotary drive assembly 34. The top ends of the two support half-shells 351a are provided with the aforementioned first mounting member 3511, and the other support half-shell 351a has the aforementioned support shell hole. The rotating shell 341 includes two interlocking rotating half-shells 341a, which enclose the interior of the rotating shell 341. The bottom of one rotating half-shell 341a forms the inner wall of the rotating shell 341 away from the support component 35, and the bottom of the other rotating half-shell 341a forms the inner wall of the rotating shell 341 near the support component 35. The top of the two rotating half-shells 341a is provided with the aforementioned second mounting member 3411, and the other rotating half-shell 341a has the aforementioned rotating shell hole.

[0074] With the above structure, in practical application, the first translation drive component 32 drives the support component 35 to move away from the trash can 20, and the second translation drive component 33 synchronously drives the rotation drive component 34 to move away from the trash can 20. This can drive the connecting rod 41, the cleaning rake 40 and the two pushers 42 to move away from the trash can 20 until the cleaning rake 20 is located at the other end of the receiving cavity 11. During the movement, the cleaning rake 40 can scoop up the cat litter clumps in the receiving cavity 11 through one end, and the cat litter is filtered out. Then, the rotary drive assembly 34 drives the connecting rod 41 to rotate counterclockwise, thereby causing the cleaning rake 40 and the two pushers 42 to rotate towards the trash can 20, i.e., counterclockwise, until the cleaning rake 40 is parallel to the bottom of the receiving cavity 11. This prevents the litter clumps on the cleaning rake 40 from falling off. Then, the first translation drive assembly 32 drives the support assembly 35 to move towards the trash can 20, and the second translation drive assembly 33 simultaneously drives the rotary drive assembly 34 to move towards the trash can 20, thereby driving the connecting rod 41, the cleaning rake 40, the two pushers 42, and the cleaning rake 40 to rotate counterclockwise. The litter clump on one end of the rake 40 moves towards the trash can 20. As the connecting rod 41 moves into the space and contacts the arc surface 2221 of the extension 222, the extension 222 is lifted upwards by the connecting rod 41. This causes the lid 22 to rotate counterclockwise relative to the trash can 20 around the pivot 221, i.e., rotate a certain angle away from the basin 10. When the support assembly 35 passes through the fourth groove 262 and extends into the clearance groove 25, and the rotation drive assembly 34 passes through the third groove 261 and extends into the clearance groove 25, as... Figure 5As shown, the first translation drive assembly 32 and the second translation drive assembly 33 stop the movement of the drive support assembly 35 and the rotation drive assembly 34, respectively, thereby stopping the movement of the connecting rod 41, the cleaning rake 40 and the two pushers 42. At this time, the connecting rod 41 is located in the clearance groove 25, the cleaning rake 40 is partially located in the basin opening 12, the clearance opening 26 and the clearance groove 25, and the two pushers 42 cooperate with the arc surface 2221 of the extension 222. Then, the connecting rod 41 is driven to rotate counterclockwise by the rotary drive assembly 34, which in turn drives the cleaning rake 40 and the two pushers 42 to rotate towards the trash can 20, i.e., in a counterclockwise direction. In this way, the two pushers 42 drive the extension 222 to rotate counterclockwise relative to the trash can 20, i.e., in a direction away from the basin 10. This drives the lid 22 to rotate counterclockwise relative to the trash can 20 around the pivot 221, i.e., in a direction away from the basin 10. This allows the end of the lid 22 away from the basin 10 to move into the trash can 20, thereby opening the trash can opening 21. At the same time as the trash can opening 21 is opened, the cat litter clumps on one end of the cleaning rake 40 can be poured into the trash can 20 through the trash can opening 21. Then, the connecting rod 41 is driven to rotate clockwise by the rotary drive assembly 34, thereby causing the cleaning rake 40 and the two pushers 42 to rotate clockwise away from the garbage bin 20 until the cleaning rake 40 is parallel to the bottom of the receiving cavity 11. Then, the support assembly 35 is driven to move away from the garbage bin 20 by the first translation drive assembly 32, and the rotary drive assembly 34 is simultaneously driven to move away from the garbage bin 20 by the second translation drive assembly 33, thereby causing the connecting rod 41, the cleaning rake 40, and the two pushers 42 to move away from the garbage bin 20 until the cleaning rake 40 corresponds to the other end of the receiving cavity 11. During the movement of the cleaning rake 40 and the two pushers 42 away from the garbage bin 20, when the support assembly 35, the rotary drive assembly 34, and the cleaning rake 40 are located at one end of the receiving cavity 11, i.e., the initial position, such as... Figure 1 , Figure 2 , Figure 3 and Figure 11As shown, since the pivot 221 is located between the center of the lid 22 and the end of the lid 22 away from the basin 10, and the lid 22 rotates relative to the garbage bin 20 in a direction away from or close to the basin 10 with the pivot 221 as the fulcrum, the lid 22 and the extension 222 will form a cantilever beam structure. Under the action of gravity, the lid 22 and the extension 222 can rotate clockwise, that is, in a direction close to the basin 10, to the initial position. At this time, the end of the lid 22 close to the basin 10 rests on the lower inner wall of the connecting groove 251, thus closing the garbage bin opening 21. Then, the connecting rod 41 is driven to rotate clockwise by the rotary drive assembly 34, thereby causing the cleaning rake 40 and the two pushers 42 to rotate clockwise away from the garbage bin 20 to their initial positions. At this time, the cleaning rake 40 is located at the other end of the receiving cavity 11. Then, the support assembly 35 is driven to move closer to the garbage bin 20 by the first translation drive assembly 32, and the rotary drive assembly 34 is simultaneously driven to move closer to the garbage bin 20 by the second translation drive assembly 33, thereby causing the connecting rod 41, the cleaning rake 40, and the two pushers 42 to move closer to the garbage bin 20 to their initial positions. Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, during the movement of the cleaning rake 40, the litter in the receiving cavity 11 can be leveled using one end of the cleaning rake 40, making it easier for the cat to use it for the next time. Thus, the cleaning work is completed. The first translation drive assembly 32 and the second translation drive assembly 33 synchronously drive the connecting rod 41 and the cleaning rake 40 to move. During the process of scooping up the litter clumps using one end of the cleaning rake 40, it is ensured that all the litter clumps are scooped up and the litter is leveled, improving the cleaning effect.

[0075] Furthermore, combined Figures 10 to 12As shown, the present invention also includes a PCB board 50, a power module, a human infrared sensor 60, and a button 70. The PCB board 50 is disposed within the inner cavity 313, specifically on the bottom of the inner cavity 313 via a base. The first translation drive assembly 32, the second translation drive assembly 33, and the rotation drive assembly 34 are all electrically connected to the PCB board 50. Specifically, the translation motor 321 of the first translation drive assembly 32 is electrically connected to the PCB board 50 via a first connecting line, the translation motor 321 of the second translation drive assembly 33 is electrically connected via a second connecting line, and the rotation motor 342 of the rotation drive assembly 34 is electrically connected to the PCB board 50 via a third connecting line 3421. In this embodiment, the third connecting line 3421 is spiral-shaped and is sleeved on the guide rod 326 of the second translation drive assembly 33. One end of the third connecting line 3421 passes through the first through hole at the top of the rotating shell 341 and is electrically connected to the rotation motor 342. The other end of the third connecting line 3421 passes through the second through hole of the lower shell 311 of the outer shell 31 and is electrically connected to the PCB board 50. Setting the third connecting line 3421 into a spiral shape and sleeved on the guide rod 326 of the second translation drive assembly 33 can save space and facilitate extension and retraction, thus facilitating the movement of the rotation drive assembly 34. Figure 11 and Figure 12 Only a portion of the third connection line 3421 is shown. The PCB board 50 is used to control the operation of the translation motor 321 of the first translation drive assembly 32, the translation motor 321 of the second translation drive assembly 33, and the rotary motor 342. By using one PCB board 50 to control the operation of three motors, fewer control components are required, reducing cost and the risk of failure. The PCB board 50 controls the operation of the translation motors 321 of the first translation drive assembly 32 and the second translation drive assembly 33, thereby enabling the first translation drive assembly 32 to drive the support assembly 35 to move closer to or further away from the garbage bin 20, and the second translation drive assembly 33 to drive the rotary drive assembly 34 to move closer to or further away from the garbage bin 20. The PCB board 50 also controls the translator motors 321 of the first translation drive assembly 32 and the second translation drive assembly 33 to stop operating, thereby stopping the support assembly 35 from moving closer to or further away from the garbage bin 20, and stopping the rotary drive assembly 34 from moving closer to or further away from the garbage bin 20. The PCB board 50 controls the operation of the rotary motor 342, thereby enabling the connecting rod 41 to rotate. The PCB board 50 also controls the rotary motor 342 to stop operating, thereby stopping the connecting rod 41 from rotating.

[0076] The power module is electrically connected to the PCB board 50 and supplies power to the PCB board 50. A power interface is located at the bottom of the lower shell 311 of the outer casing 31. This power interface is electrically connected to the PCB board 50 and can be connected to an external power source via a power cable, allowing the power module to be charged by the external power supply.

[0077] The human infrared sensor 60 is located at the bottom of the U-shaped cavity 314 and is electrically connected to the PCB board 50. When the pet cat enters the receiving cavity 11, the human infrared sensor 60 can detect the pet cat and output a signal to the PCB board 50. The PCB board 50 can then control the translation motor 321 of the first translation drive assembly 32, the translation motor 321 of the second translation drive assembly 33, and the rotary motor 342 to stop working. This stops the connecting rod 41, the cleaning rake 40, and the two pushing parts 42 from moving, thus preventing the connecting rod 41, the cleaning rake 40, and the two pushing parts 42 from harming the pet cat. When the pet cat leaves the receiving cavity 11, the human infrared sensor 60 can no longer detect the pet cat. At this time, the human infrared sensor 60 outputs a signal to the PCB board 50, which can then control the start of the translation motor 321 of the first translation drive assembly 32, the translation motor 321 of the second translation drive assembly 33, and the rotary motor 342. This allows the connecting rod 41, the cleaning rake 40, and the two pushing parts 42 to continue moving, thus enabling the corresponding operations to continue.

[0078] Button 70 is located at the end of the upper shell 312 of the outer shell 31 away from the trash can 20. Button 70 is electrically connected to the PCB board 50. In this embodiment, there are four buttons 70, including a first button, a second button, a third button and a fourth button. The first button is a power button, the second button is a sleep button, the third button is used to set the time for cleaning cat litter, and the fourth button is a mode button.

[0079] This invention, through the inclusion of a litter bin 20 and a cleaning device, scoops up litter clumps from the receiving cavity 11, rotates the lid 22 of the litter bin 20 away from the basin 10 to open the litter bin opening 21, and simultaneously pours the scooped litter clumps into the litter bin 20 through the opening 21, while also smoothing out the litter in the receiving cavity 11. The litter bin 20 collects the litter clumps, thus automatically cleaning the litter clumps in the receiving cavity 11, saving time and effort and meeting user needs. Furthermore, smoothing out the litter makes it easier for the cat to excrete next time. Meanwhile, the PCB board 50, human infrared sensor 60, button 70, power module, first translation drive component 32, and second translation drive component 33 are all integrated on the housing 31. The housing 31 is detachably mounted on the top of the basin 10, which facilitates the removal of the cleaning device, PCB board 50, human infrared sensor 60, button 70, and power module as a whole.
