[0067] REFERENCE Figures 1 to 3 A pet litter box, comprising: a base 1, a litter box 2 detachably mounted in the base 1, an upper shell 3 detachably connected to the base 1 or the litter box 2, the upper shell 3 being connected with a barrier 4 for screening litter and litter clumps, both sides of the litter box 2 being detachably connected with a driving assembly 5, the driving assembly 5 being used to drive the litter box 2 to rotate, so that the litter in the litter box 2 is screened into a space enclosed by the barrier 4, the upper shell 3 and the litter box 2, and the litter clumps are screened out of the barrier 4 and fall into a garbage box 6;

[0068] The base 1 is detachably connected with a plurality of supporting legs 7 and a garbage box 6 for containing litter clumps at the bottom;

[0069] When stored, the upper shell 3, the driving assembly 5, the supporting legs 7 and the garbage box 6 can be completely put into the litter box 2.

[0070] The pet litter box in the embodiment can be disassembled and connected. When being transported or stored, the upper shell 3, the driving assembly 5, the support leg 7 and the garbage box 6 are stored in the litter box 2. At this time, the volume of the entire pet litter box is equal to the volume of the litter box 2, the volume is reduced, the floor space is reduced, the storage space of the pet litter box is compressed, the logistics cost and the packaging material are reduced, and the cost spent on packaging and transportation is reduced.

[0071] Before use, the support leg 7 and the garbage box 6 are assembled below the base 1, the upper shell 3 is installed on the litter box 2, the fence 4 is installed in the upper shell 3 and the litter box 2, the driving assembly 5 is installed on both sides of the litter box 2, and then the assembled litter box 2, the upper shell 3, the fence 4 and the driving assembly 5 are jointly installed above the base 1. It is fast and convenient for users to operate.

[0072] Specifically, the litter box 2 is an open cavity, and the cavity volume of the litter box 2 is greater than the volume of the upper shell 3, so that the upper shell 3 can be completely stored in the litter box 2. Similarly, the garbage box 6 also has an open cavity, and the support leg 7, the fence 4 and the driving assembly 5 can be stored therein.

[0073] Specifically, the base 1 is provided with a mounting cavity, and the depth of the mounting cavity is greater than or equal to the depth of the litter box 2. After the components are stored in the litter box 2, the litter box 2 is installed in the base 1.

[0074] Specifically, the connection relationship between the litter box 2 and the upper shell 3, the connection relationship between the base 1 and the litter box 2, and the connection relationship between the support leg 7 and the base 1 can be one or a combination of magnetic attraction, clamping, pin connection and key connection.

[0075] Specifically, the fence 4 is rotationally connected with the upper shell 3.

[0076] The application provides two embodiments of the driving assembly 5:

[0077] Referring to Figure 5 , Figure 6 , Figure 13 and Figure 16 , the common structure of the two embodiments is that the driving assembly 5 includes an inner shell 51 connected with the litter box 2 and an outer shell 52 connected with the inner shell 51; the bottom of the outer shell 52 is provided with a plug-in part 521, and the base 1 is provided with a plug-in hole 11 corresponding to the plug-in part 521.

[0078] The inner shell 51 is provided with a plurality of teeth 50 on the inner circumferential side;

[0079] The driving member 53 is fixed in the shell 52, and the output end of the driving member 53 is connected with a driving gear 54 engaged with the teeth 50. The driving member 53 drives the driving gear 54 to rotate, so as to drive the inner shell 51 and the sand basin 2 to rotate relative to the base 1 and the shell 52.

[0080] After the pet defecates, the sand is coagulated to form a sand ball. At this time, the sand basin 2 contains sand balls and sand particles. When the sand ball is cleaned, the driving member 53 drives the driving gear 54 to rotate by output power. The driving gear 54 is engaged with the teeth 50 of the inner shell 51, so that the inner shell 51 drives the sand basin 2 to rotate. The sand basin 2 is rotated to a certain angle, so that the upper shell 3 is located at the bottom (the state is referred to as Figure 2 ). At the same time, in the process of rotating the sand basin 2, the sand and sand balls fall into the space enclosed by the upper shell 3 and the sand basin 2 under the action of gravity. The surrounding barrier 4 is provided with a plurality of sieve holes with a hole diameter larger than that of the sand particles and smaller than that of the sand balls, so that the sand balls are sieved out of the surrounding barrier 4. The sand balls isolated outside fall into the garbage box 6 under the action of gravity. When there is no sand ball on one side of the sand basin 2 and the surrounding barrier 4, the pet sand basin is in a state of dumping sand balls. The driving assembly 5 drives the sand basin 2 to reset. The sand falls into the sand basin 2 through the surrounding barrier 4 for the pet to use for defecation. The whole process is driven by the driving member 53, and no human intervention is required.

[0081] In the prior art, the teeth 50 are arranged outside the inner shell 51, and the driving member 53 is fixed in the base 1. Such an arrangement makes the driving assembly 5 have a large volume, which is not conducive to the storage of the driving assembly 5 in the sand basin.

[0082] Specifically, the surrounding barrier 4 can completely cover the cross section of the cavity enclosed by the upper shell 3 and the sand basin 2. The sieve holes are uniformly distributed on the surrounding barrier 4 to ensure that the sand and sand balls can be completely separated.

[0083] More specifically, the side of the inner shell 51 facing the sand basin 2 is provided with a clamping joint 511 for clamping the edge of the sand basin 2 to fix the relative position of the sand basin 2 and the driving assembly 5.

[0084] The clamping joint 511 is clamped with the edge of the sand basin 2. When the driving assembly 5 drives the sand basin 2 to rotate, the sand basin 2 and the driving assembly 5 are prevented from being unstable due to too few connection points between them, so as to ensure the normal operation of the screening function.

[0085] In addition, the two sides of the sand basin 2 are clamped with the driving assembly 5, which can improve the stability of the sand basin 2 when rotating and ensure the normal operation of the screening function.

[0086] Specifically, when the pet litter box is in a state of dumping litter clumps, in order to avoid the swing of the fence 4 to the direction of the base 1, a gap for the litter clumps to pass through is formed between the fence 4 and the litter box 2, therefore, the upper shell 3 is provided with a fence limiting block 17, when the pet litter box is in a state of dumping litter clumps, the fence limiting block 17 is used to limit the swing of the fence 4 to the direction of the base 1, to ensure the effect of the fence 4 screening the litter clumps.

[0087] It can be understood that the litter box 2 and the drive assembly 5 on both sides thereof form a rotating shaft, and the garbage box 6 is arranged on one side of the rotating shaft.

[0089] Referring to Figure 5 and Figure 6 , the outer shell 52 is provided with a first gap slot 522 for the hand to extend into, the first connecting rod 523 is arranged between the outer shell 52 and the inner shell 51, the first elastic member 524 is arranged between the first connecting rod 523 and the inner wall of the outer shell 52, and the first connecting rod 523 is partially located in the first gap slot 522 along the extension direction of the first elastic member 524;

[0090] The side of the first connecting rod 523 close to the base 1 is provided with a first connecting rod wedge block 525, the plug-in wedge block 526 is slidably connected to the first connecting rod wedge block 525, and the plug-in wedge block 526 can pass through the first slot and the second slot 528, so as to fix the drive assembly 5 to the base 1;

[0091] The second elastic member 527 is arranged between the plug-in wedge block 526 and the drive assembly 5; when the first connecting rod 523 is pulled upward, the first elastic member 524 is compressed, the plug-in wedge block 526 is pressed by the first connecting rod wedge block 525 to extrude the second elastic member 527, and the plug-in wedge block 526 is retracted into the drive assembly 5.

[0092] During the process of fixing the drive assembly 5 to the base 1, the plug-in wedge block 526 is resisted by the side wall of the plug-in hole 11, the second elastic member 527 is retracted, until the first slot is aligned with the second slot 528, the restriction on the second elastic member 527 is released, the second elastic member 527 is stretched, so that the plug-in wedge block 526 passes through the second slot 528 and the first slot, thereby fixing the drive assembly 5 to the base 1;

[0093] When the driving assembly 5 is removed from the base 1, the finger is inserted into the first displacement slot 522, the first connecting rod 523 in the first displacement slot 522 is pressed into the shell 52, the first elastic member 524 is compressed, the vertical movement of the first connecting rod 523 is converted into the horizontal movement of the insertion wedge block 526, the first elastic member 524 is compressed, the insertion wedge block 526 is retracted into the shell 52, the restriction on the first slot is released, and thus the driving assembly 5 is removed from the base 1.

[0094] The driving assembly 5 is simple in dismounting structure, convenient to operate, and easy for users to assemble and operate.

[0095] Specifically, the first displacement slot 522 is arranged on the side wall of the shell 52, and specifically on the side of the driving assembly 5 away from the sand basin 2.

[0096] Specifically, the extension direction of the first elastic member 524 is perpendicular to the horizontal direction.

[0097] Specifically, the second elastic member 527 extends in the horizontal direction.

[0098] With reference to Figure 8 and Figure 9 , this embodiment is the second embodiment of the driving assembly 5, and on the basis of the common structure, this embodiment further has the following structure: in one embodiment, in order to facilitate user operation and facilitate the installation of the driving assembly 5 on the sand basin 2, a second through slot (not shown in the figure) is arranged at the adjacent position of the inner shell 51 and the sand basin 2; the driving assembly 5 further comprises a second connecting rod 513 arranged in the inner shell 51, a first button 514 arranged on the inner shell 51, a support member 515 fixed to the inner wall of the inner shell 51, a rotating member 516 rotatably connected to the support member 515, a fixing member 517 fixed to the inner wall of the inner shell 51, and a third elastic member 518 arranged between the fixing member 517 and the second connecting rod 513.

[0099] The two sides of the rotating center of the rotating member 516 are respectively the A end and the B end;

[0100] One end of the first button 514 extends out of the inner shell 51, and the other end is rotatably connected to the A end of the rotating member 516;

[0101] With reference to Figure 7 and Figure 8 , one end of the second connecting rod 513 extends into the second through slot, and the other end is rotatably connected to the B end;
