[0024] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Please refer to Figure 1 , the litter box 100 includes: a housing 10, a basin body 20, and a driving module 30. The housing 10 is provided with an installation cavity 101 and an opening 102. The opening 102 communicates with the installation cavity 101. The basin body 20 is rotatably arranged in the installation cavity 101. The basin body 20 is used for loading cat litter. The opening of the housing 10 is for cats to enter and exit the housing. For example, when a cat needs to defecate, it enters the housing 10 through the opening 102 and lies on the cat litter in the basin body 20. The excrement discharged by the cat is fused with the cat litter to form lumps. The driving module 30 is used to drive the basin body 20 to rotate so that the basin body 20 is tilted to realize tilting the cat litter in the basin body, or tilting the lumps of excrement and cat litter in the basin body.

[0026] For the above-mentioned basin body 20, please refer toFigure 2 The litter box includes a screen 203, and the basin body 20 is further provided with a sand loading groove 201. Among them, a sand collecting cavity 211 and a communication port 212 are provided on the side wall of the sand loading groove 201. The communication port 212 connects the sand collecting cavity 211 and the sand loading groove 201. The screen 203 is detachably arranged at the communication port 212. The sand loading groove 201 is used for loading cat litter. The screen 203 allows the cat litter to pass through, but does not allow the lumps formed by the melting of the cat litter and excrement to pass through. Therefore, when the basin body 20 inclines towards the sand collecting cavity 211, the cat litter flows from the sand loading groove 201 into the sand collecting cavity 211, but the lumps formed by the melting of the cat litter and excrement still remain in the sand loading groove 201. As the basin body 20 continues to incline towards the sand collecting cavity 211, the cat litter is concentrated in the sand collecting cavity 211, and the lumps formed by the melting of the cat litter and excrement flow out of the sand loading groove 201 along the side wall of the sand loading groove 201, realizing the discharge of the lumps formed by the melting of the cat litter and excrement. When the basin body 20 returns to its original position, the cat litter in the sand collecting cavity 211 returns to the sand loading groove 201. When the basin body 20 inclines towards the other side away from the sand collecting cavity 211, the cat litter in the sand loading groove 201 flows out of the sand loading groove 201 along the other side wall of the sand loading groove 201 away from the sand collecting cavity 211, realizing the function of pouring out the cat litter.

[0027] In some embodiments, the shape of the other side wall of the sand loading groove 201 away from the sand collecting cavity 211 is set to be arc-shaped to facilitate the outflow of the cat litter in the sand loading groove 201.

[0028] Connecting columns 202 are provided on the outer surface of the basin body 20. The connecting columns 202 deviate from the rotation axis of the basin body 20 rotating relative to the installation cavity 101. The connecting columns 202 are used for the driving module 30 to drive the basin body 20 to rotate relative to the installation cavity 101.

[0029] For the above driving module 30, please refer to Figure 3 and Figure 4 The driving module 30 further includes a linear driving component 301, a tilting component 302 and a driving rod 303.

The motor is fixed in the installation cavity 101. The output shaft of the motor is fixed to the gear 312. The gear 312 meshes with the rack 311. When the motor rotates, the gear 312 drives the rack 311 to perform a linear reciprocating motion. The tilting component 302 further includes a fixing member 324 and a tilting member 322. One end of the fixing member 324 is fixed to the inner surface of the housing 10. One end of the tilting member 322 is fixed to the other end of the fixing member 324. The tilting member 322 is perpendicular to the fixing member 324.

[0031] The connecting column 202 is inserted into the connecting hole 334. The connecting column 202 can move within the connecting hole 334. The linear drive assembly 301 is rotatably connected to the other end of the drive rod 303. The linear drive assembly 301 drives the other end of the drive rod 303 to perform linear reciprocating motion along the first axis.

[0032] The drive rod 303 further includes a first rod body 335 and a second rod body 336. The rack 311 of the linear drive assembly 301 is rotatably connected to one end of the first rod body 335. The other end of the first rod body 335 is connected to one end of the second rod body 336. The connecting hole 334 is provided at the end of the other end of the second rod body 336, so that the connecting hole 334 is provided at the end of one end of the drive rod 303. The drive rod 303 is provided with a tilting groove 333. The tilting groove 333 is arranged along the length direction of the first rod body 335. The included angle between the first rod body 335 and the second rod body 336 is greater than 90 degrees.

[0033] Wherein, the other end of the tilting member 322 is inserted into the tilting groove 333, and the other end of the tilting member 322 can move along the tilting groove 333, so that the tilting assembly 302 is inserted into the tilting groove 333, and the tilting assembly 302 can move along the tilting groove 333. When the linear drive assembly 301 drives the other end of the drive rod 303 to perform linear reciprocating motion along the first axis, the tilting member 322 moves along the tilting groove 333, so that one end of the drive rod 303 moves upward or downward under the limitation of the tilting groove 333 and the tilting member 322, so as to lift one side of the basin body 20 or pull down one side of the basin body 20, thereby realizing the tilting of the basin body 20. Wherein, the first axis is perpendicular to the rotation axis of the basin body 20 relative to the housing 10.

[0034] So that the basin body 20 can move upward or downward along the track. It should be noted that when the first rod moves upward, the basin body tilts to the left to realize the function of cleaning the basin body. When the second rod body moves upward, the basin body tilts to the right to realize the function of emptying the cat litter box.

[0035] Please continue to refer to Figure 4, in the implementation of the present invention, the number of the connecting columns 202 and the driving rods 303 is two. The two connecting columns 202 are respectively located on the same side of the housing 10, and the two connecting columns 202 are respectively located on both sides of the rotation axis of the basin body 20 rotating relative to the housing 10. The two driving rods 303 are arranged in a cross shape. The tilting assembly 302 is respectively inserted into the tilting grooves 333 of the two driving rods 303. When the linear driving assembly 301 is used to drive the other ends of the two driving rods 303 to perform linear reciprocating motion, under the cooperation of the tilting assembly 302 and the two tilting grooves 333, the end of one end of one driving rod 303 drives one connecting column 202 to move upward, and the end of one end of the other driving rod 303 drives the other connecting column 202 to move downward, or the end of one end of one driving rod 303 drives one connecting column 202 to move downward, and the end of one end of the other driving rod 303 drives the other connecting column 202 to move upward, so that the basin body 20 is more stable when rotating.

[0036] In some embodiments, the driving rod 303 further includes a first rod body, a second rod body and a connecting piece. The first rod body is rotatably connected to the second rod body through the connecting piece. One end of the first rod body is connected to the motor through the motor rotating shaft, and the other end of the first rod body is connected to the second rod body. In the embodiment of the present invention, the included angle between the first rod body and the second rod body can be adjusted according to the upward or downward movement trajectory of the driving rod. For example, when the movement stroke of the cat litter basin is too large, the included angle between the first rod body and the second rod body is greater than 90 degrees. When the movement stroke of the cat litter basin 100 is too small, the included angle between the first rod body and the second rod body is less than 90 degrees, and the angle is adjusted according to the required movement trajectory of the basin body.

[0037] In some embodiments, please refer to Figure 5, the litter box 100 further includes a first support column 40, a second support column 50, a first rotating shaft 60, a second rotating shaft (not shown in the figure), a tray 80, and a cover plate (not shown in the figure).

One end of the second rotating shaft is fixed to the basin body 20, and the other end of the second rotating shaft is rotatably arranged on the second support column 50. The basin body 20 rotates along the first rotating shaft 60 and the second rotating shaft. When the basin body 20 is subjected to the thrust of the first rod 335 and the second rod 336, the basin body 20 will tilt left or right along the first rotating shaft 60 on the first support column 40 and the second rotating shaft on the second support column 50, so that the cat litter in the basin body 20 can flow into the sand collection cavity 211, and the lumps of excrement and cat litter are discharged, or the cat litter in the basin body 20 is discharged.

[0038] The tray 80 is arranged in the installation cavity 101, and the tray 80 is located below the basin body 20.
