Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pet toilets, in particular to a pet toilet. BACKGROUND

[0002] A pet toilet such as a cat litter box is a device for storing cat litter, and a trained cat will come to the cat litter box when it needs to excrete and excrete the excrement on the cat litter in the cat litter box. The urine and solid feces excreted by the cat will clump in the cat litter box, and timely treatment is needed to avoid odor, otherwise the pet cat will reject to excrete in the cat toilet. At present, there are both automatic cleaning cat litter boxes and manual cleaning cat litter boxes on the market. Due to the price reason, the manual cleaning cat litter boxes account for the majority, but the user needs to hold a litter shovel to repeatedly screen and leak cat litter to achieve the purpose of cleaning the cat litter box. The operation is complicated, time-consuming and laborious. SUMMARY

[0003] The present application provides a pet toilet to solve the technical problem that the user needs to hold a litter shovel to repeatedly screen and leak cat litter during the use of a manual cleaning cat litter box, which leads to complicated operation, time-consuming and laborious.

[0004] The present application provides a pet toilet, comprising: a base; a bowl body rotatably connected to one end of the base, a sand groove is arranged on the side of the bowl body away from the base, a sieve plate is arranged in the sand groove, the sieve plate separates the sand groove into a first chamber and a second chamber, the first chamber is provided with a passage for the pet to enter and exit, and the second chamber is in a closed structure except that it is communicated with the first chamber through sieve holes on the sieve plate; a driving member for driving the bowl body to overturn relative to the base to switch the bowl body between a use position and a cleaning position; In the use position, the bowl body is stacked on the base, the groove bottom wall of the sand groove is inclined downward from the second chamber to the first chamber, so that the cat litter slides to the first chamber under the action of gravity; in the cleaning position, the bowl body is overturned, and the groove bottom wall of the sand groove is inclined downward from the first chamber to the second chamber, so that the unclumped sand blocks fall into the second chamber through the sieve holes of the sieve plate, and the clumped sand blocks are blocked by the sieve plate due to the size being greater than the sieve holes; wherein a guide surface is arranged on the side of the sieve plate facing the first chamber, the guide surface is inclined to the depth direction of the sand groove and extends obliquely from the edge of the sieve plate to the outside of the sand groove, and in the cleaning position, the clumped sand blocks slide along the guide surface and are guided out to the outside of the first chamber.

[0005] In one embodiment, the drive component includes a pressure rod and a linkage rod connected at an angle. The pressure rod has a first end and a second end opposite to each other, and the linkage rod has a third end and a fourth end opposite to each other. The first end extends out of the pet toilet for user operation. The second end and the third end are both rotatably connected to the base via a first axle pin, and the fourth end is rotatably connected to the basin via a second axle pin. The first axle pin and the second axle pin are parallel to each other. The second end and the third end are provided with a limiting groove and a limiting block, respectively. The end of the limiting block is accommodated in the limiting groove and can rotate relative to the first pivot pin within a preset angle range. In the use position, the limiting block abuts against an inner wall of the limiting groove along the circumference of the first pivot pin, and the included angle between the pressure rod and the linkage rod is a first angle. When the first end is pressed down, the pressure rod first rotates relative to the linkage rod around the first pivot pin to the preset angle, and then the limiting block abuts against another opposite inner wall of the limiting groove. The pressure rod and the linkage rod are linked and then rotate synchronously to drive the basin to flip around the first pivot pin, switching from the use position to the cleaning position. In the cleaning position, the included angle between the pressure rod and the linkage rod is a second angle, which is greater than the first angle.

[0006] In one embodiment, there are two pressure rods and two linkage rods. One pressure rod and one linkage rod form a set of components. The two sets of components are symmetrically arranged on opposite sides of the basin along the axial direction of the first shaft pin. The driving component also includes an operating rod, which is connected between the two first ends and is parallel to the first shaft pin and the second shaft pin.

[0007] In one embodiment, the driving component includes a push rod and a rocker arm. The push rod is movably disposed within the base in a vertical direction, and its upper end is used to abut and lift the bottom of the basin when moving upward, so as to drive the basin to flip up and down relative to the base. The rocker arm is rotatably connected to the base, with one end extending outside the base for the user to press down, and the other end connected to the lower end of the push rod. When the user presses down the rocker arm, the push rod moves upward, causing the basin to switch from the use position to the cleaning position.

[0008] In one embodiment, a damping shaft protrudes from the outer wall of the basin, and an upwardly extending arc-shaped support surface protrudes from the upper edge of the base. The arc-shaped support surface corresponds to the movement trajectory of the damping shaft to dampen and abut against the damping shaft. When the basin is flipped upward relative to the base until the bottom wall of the litter trough is horizontal, the damping shaft abuts against and supports the support arc surface, so that the basin can be stably stopped at this horizontal position so as to spread the cat litter evenly.

[0009] In one embodiment, during the flipping process of the basin, the damping shaft slides along the arc-shaped support surface and can be suspended at multiple angular positions corresponding to the arc-shaped support surface.

[0010] In one embodiment, a limiting rod is connected between the base and the basin. The limiting rod has a fifth end and a sixth end. The fifth end is rotatably connected to the basin via a third shaft pin, and the sixth end is rotatably connected to the base via a fourth shaft pin. Both the third shaft pin and the fourth shaft pin are parallel to the width direction of the sand trough. The fifth end is provided with a first groove extending along its axial direction, and the end of the third pin is limited to the first groove and moves in the first groove as the basin is flipped, so as to limit the maximum flipping angle of the basin; and / or, the sixth end is provided with a second groove extending along its axial direction, and the end of the fourth pin is limited to the second groove and moves in the first groove as the basin is flipped, so as to limit the maximum flipping angle of the basin.

[0011] In one embodiment, the upper end face of the base is recessed to form a groove; in the use position, the basin is at least partially accommodated in the groove, and one end of the basin away from the second chamber abuts against the bottom wall of the groove, and the other end of the basin is rotatably connected to the inner side wall of the groove, so that the bottom wall of the sand trough is kept inclined downward from the second chamber toward the first chamber.

[0012] In one embodiment, the upper surface of the base is flat, and the bottom wall of the sand trough is inclined relative to the horizontal plane; in the use position, the basin is stacked on the base, such that the bottom wall of the sand trough is inclined downward from the second chamber toward the first chamber.

[0013] In one embodiment, the upper surface of the base is inclined relative to the horizontal plane, and the bottom wall surface of the basin is inclined relative to the horizontal plane; in the use position, the basin is stacked on the base, and the upper surface of the base is in contact with the bottom wall surface of the basin, so that the bottom wall of the sand trough is kept inclined downward from the second chamber toward the first chamber.

[0014] In one embodiment, the pet toilet further includes a waste collection box, which is attached to the outer wall of the basin on the side where the second chamber is located, and the upper edge of the opening of the waste collection box is not higher than the height of the base; in the cleaning position, the clump of litter slides down from the first chamber into the waste collection box along the guide surface.

[0015] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects: The pet toilet provided by this invention achieves a high degree of automation and user-friendliness in the cat litter use and cleaning process by cleverly combining a flip-up basin, an inclined litter trough bottom wall, a sieve plate, and a guide surface. In the use position, the bottom wall of the litter trough slopes downwards from the second chamber towards the first chamber, allowing clean cat litter to naturally slide down under gravity and collect in the first chamber, which has an inlet / outlet passage. This facilitates pets stepping on and burying their excrement, improving the toileting experience. When the basin is switched to the cleaning position, it flips, causing the litter trough bottom wall to tilt in the opposite direction. Unclumped cat litter falls through the sieve holes on the sieve plate into the closed second chamber for temporary storage, while larger litter clumps are effectively blocked from passing through the sieve holes and are discharged directly to the outside of the pet toilet under their own gravity along the guide surface of the sieve plate. The pet toilet provided by this invention eliminates the need for users to manually sift or handle waste, significantly improving cleaning efficiency and hygiene safety. Simultaneously, the second chamber is a closed structure, preventing dust spillage and avoiding accidental contact with recycled cat litter by pets, ensuring a clean environment. Furthermore, the entire flipping-separation-extraction process only requires operating the drive component once, making it simple, time-saving, and labor-saving. In addition, the compact structure and reliable component linkage reduce manufacturing costs and enhance product durability. In summary, this invention improves pet toilet comfort while significantly optimizing the user's daily maintenance experience, demonstrating good practical value and market potential.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Combined with parameters Figure 1 and Figure 2This invention provides a pet toilet 1, including a base 10, a basin 20, and a drive unit 30. The base 10 serves as the supporting body of the pet toilet 1. The basin 20 is rotatably connected to one end of the base 10. A sand trough 21 is provided on the side of the basin 20 facing away from the base 10. A sieve plate 22 is provided inside the sand trough 21. The edge of the sieve plate 22 abuts against the bottom wall 214 and side wall 215 of the sand trough 21. The sieve plate 22 divides the sand trough 21 into a first chamber 211 and a second chamber 212. The first chamber 211 has a passage 213 for the pet to enter and exit. The second chamber 212 is sealed except that it communicates with the first chamber 211 through the sieve holes 221 on the sieve plate 22. The drive unit 30 is located between the base 10 and the basin 20 and is used to rotate the basin 20 relative to the base 10, so that the basin 20 is in the use position (…). Figure 1 ) and clean position ( Figure 2 Switch between )

[0023] Specifically, Figure 1 The illustration shows the usage position, with the basin 20 stacked on the base 10. The litter trough 21 tilts downward from the second chamber 212 toward the first chamber 211, causing the cat litter to slide and accumulate in the first chamber 211 under the action of gravity. The pet enters the first chamber 211 through the passage 213 to relieve itself. The cat litter comes into contact with the pet's excrement to form a mixture of clumped litter (cat litter with excrement) and unclumped cat litter (clean cat litter). Figure 2 The illustration shows that in the cleaning position, the basin 20 is flipped so that the bottom wall 214 of the litter trough 21 tilts downwards from the first chamber 211 toward the second chamber 212. This allows unclumped litter to fall into the second chamber 212 through the sieve holes 221, while clumped litter, being larger than the sieve holes 221, is blocked by the sieve plate 22 within the first chamber 211, thus separating the clumped litter from the unclumped litter. The sieve plate 22 has a guide surface 222 on the side facing the first chamber 211. The guide surface 222 is inclined along the depth direction of the litter trough 21 and extends inclinedly from the edge of the sieve plate 22 toward the outside of the litter trough 21. In the cleaning position, the clumped litter slides down along the guide surface 222 and is discharged to the outside of the first chamber 211. It should be noted that the downward tilt of the bottom wall 214 of the litter trough 21 can be a straight tilt or a curved tilt; the drive source of the drive unit 30 can be manual or motor-driven.

[0024] The pet toilet 1 provided by the present invention achieves a high degree of automation and humanization in the cat litter use and cleaning process by cleverly combining a flip-up basin 20, a bottom wall 214 of an inclined litter trough 21, a sieve plate 22, and a guide surface 222. In the use position, the bottom wall 214 of the litter trough 21 slopes downwards from the second chamber 212 towards the first chamber 211, allowing clean cat litter to naturally slide down under gravity and concentrate in the first chamber, which has an inlet / outlet channel 213. This facilitates pets stepping on and burying their excrement, improving the toileting experience. When the basin 20 is switched to the cleaning position, the basin 20 flips, causing the bottom wall 214 of the litter trough 21 to tilt in the opposite direction. Unclumped cat litter falls through the sieve holes 221 on the sieve plate 22 into the closed second chamber 212 for temporary storage, while larger litter clumps are effectively blocked in the first chamber 211 because they cannot pass through the sieve holes 221. Under their own gravity, they are discharged directly to the outside of the first chamber 211 along the guide surface 222 of the sieve plate 22. The pet toilet 1 provided by this invention eliminates the need for users to manually sift or handle waste, significantly improving cleaning efficiency and hygiene safety. Simultaneously, the second chamber 212 is a closed structure to ensure the dryness and cleanliness of the recycled cat litter. Furthermore, the entire flipping-separation-extraction process only requires one operation of the drive component 30, making it simple, time-saving, and labor-saving. In addition, the compact structure and reliable component linkage reduce manufacturing costs and enhance product durability. In summary, this invention improves pet toilet comfort while significantly optimizing the user's daily maintenance experience, demonstrating good practical value and market prospects.

[0025] Alternatively, in one embodiment, reference 1 and Figure 2 The driving component 30 includes a pressure rod 31 and a linkage rod 32 connected at an angle. The pressure rod 31 has a first end 311 and a second end 312 opposite to each other, and the linkage rod 32 has a third end 321 and a fourth end 322 opposite to each other. The first end 311 extends outside the pet toilet 1 for user operation. The second end 312 and the third end 321 are both rotatably connected to the base 10 via a first pin 41, and the fourth end 322 is rotatably connected to the basin 20 via a second pin 42. The first pin 41 and the second pin 42 are parallel to each other. Figure 1 or Figure 2 As shown, the axes of the two pins are parallel to the width direction of the basin 20, and the three points where the first end 311, the second end 312 (or the third end 321) and the fourth end 322 are located are coplanar.

[0026] Furthermore, combined Figures 1-3In this embodiment, one of the second end 312 and the third end 321 is provided with a limiting groove 331, and the other is provided with a limiting block 332. The end of the limiting block 332 is accommodated in the limiting groove 331 and can rotate relative to the first shaft pin 41 within a preset angle range. In the use position, the limiting block 332 abuts against an inner sidewall of the limiting groove 331 along the circumference of the first shaft pin 41, and the included angle between the pressure rod 31 and the linkage rod 32 is a first angle. When the first end 311 is pressed down, the pressure rod 31 first rotates relative to the linkage rod 32 around the first shaft pin 41 to the previous preset angle, and then the limiting block 332 abuts against another opposite inner sidewall of the limiting groove 331 along the circumference of the first shaft pin 41. At this time, the pressure rod 31 and the linkage rod 32 form a linkage, and the two rotate synchronously to drive the basin 20 to flip around the first shaft pin 41, switching from the use position to the cleaning position. In the cleaning position, the included angle between the pressure rod 31 and the linkage rod 32 is the second angle, which is greater than the first angle.

[0027] It is understandable that the angled connection between the pressure rod 31 and the linkage rod 32, along with their preset angle of relative rotation, serves to prevent accidental contact with the drive component 30. The preset angle provides a buffer before the litter box 20 flips, preventing the user or pet from accidentally flipping the litter box 20 upon touching the pressure rod 31 or the linkage rod 32, which could cause cat litter to spill out of the litter box 21. This ensures the cleanliness of the area around the pet toilet 1 and the cleanliness of the cat litter. Here, the pressure rod 31 and the linkage rod 32 form a seesaw structure. Pressing down the first end 311 causes the fourth end 322 to rise, which in turn drives the litter box 20 to flip. Therefore, in other embodiments, a preset angle can be set, where the second end 312 and the third end 321 remain fixedly connected, as long as the drive component 30 can achieve the seesaw process. It should also be noted that the limiting block 332 and the limiting groove 331 cooperate to form an angle limiting structure 33. The limiting groove 331 can be an arc-shaped groove, and the limiting block 332 can be a protruding post. Alternatively, the limiting groove 331 can be a gap groove, and the limiting block 332 can be a flange.

[0028] Alternatively, in one embodiment, in conjunction with reference to Figure 1 and Figure 2The number of pressure rods 31 and linkage rods 32 are both two. One pressure rod 31 and one linkage rod 32 constitute a set of components 301. The two sets of components 301 are symmetrically arranged on opposite sides of the basin 20 along the axial direction of the first shaft pin 41. The driving component 30 also includes an operating rod 34, which is connected between the two first ends 311 and is parallel to the first shaft pin 41 and the second shaft pin 42. The arrangement of components 301 on both sides enhances the overall balance of the pet toilet 1 and greatly improves the operational balance of the entire driving component 30. Users can clean the pet toilet 1 by directly applying force to press down the operating rod 34, either by hand or foot. The operation is convenient and can be done with a single button. Of course, in other embodiments, only one side of the component 301 is needed to achieve the cleaning operation of the pet toilet 1, and the presence or absence of the operating rod 34 is not limited.

[0029] It should be noted that the cooperation between the pressure rod 31 and the linkage rod 32 is one of the structural methods by which the driving component 30 drives the basin 20 to flip. In other embodiments, refer to... Figure 4 The driving component 30 includes a push rod 35 and a rocker arm 36. The push rod 35 is vertically movable within the base 10, and its upper end is used to abut and lift the bottom (bottom wall 24) of the basin 20 during upward movement, thereby driving the basin 20 to rotate up and down relative to the base 10. The rocker arm 36 is rotatably connected to the base 10, with one end extending outside the base 10 for user pressing down, and the other end connected to the lower end of the push rod 35. When the user presses down the rocker arm 36, the push rod 35 moves upward, switching the basin 20 from the use position to the cleaning position. Here, a corresponding angle limiting structure can also be set at the rotatable connection position between the rocker arm 36 and the base 10 to prevent accidental touch and limit the maximum rotation angle of the rocker arm 36. The angle limiting structure here is exactly the same as in the aforementioned embodiment one, and the specific repetitive structure will not be described again here. Of course, in other embodiments, a vertically lifting structure can be provided between the base 10 and the basin 20 to lift the basin 20 and flip it relative to the base 10. In this application, any structure that can drive the basin 20 to flip up and down relative to the base 10 should be protected.

[0030] Optionally, in one embodiment, combined with Figure 1 and Figure 5The outer wall of the basin 20 is provided with a damping shaft 23, and the upper edge of the base 10 is provided with an upwardly extending arc-shaped support surface 11. The arc-shaped support surface 11 corresponds to the movement trajectory of the damping shaft 23. When the basin 20 is flipped upward relative to the base 10 until the bottom wall of the litter trough 21 is horizontal, the damping shaft 23 abuts against and supports the arc-shaped support surface 11, so that the basin 20 can be stably stopped at this horizontal position to spread the cat litter evenly. It can be understood that during the flipping process of the basin 20, the damping shaft 23 slides along the arc-shaped support surface 11 and can be suspended at multiple angle positions corresponding to the arc-shaped support surface 11. Spreading the cat litter evenly can improve the comfort of the pet when using the toilet; on the other hand, it can prevent the cat litter from accumulating excessively on the side of the first chamber 211 away from the second chamber 212. When the pet digs, the cat litter is easily scattered out of the litter trough 21, resulting in an unclean environment around the pet toilet and waste of cat litter. Therefore, spreading the cat litter evenly can also ensure the cleanliness of the area around the pet toilet and the clean use of cat litter. Of course, when the basin 20 is in use, provided that the inclination of the bottom wall 214 of the litter trough 21 is not very large, the cat litter will not be highly concentrated at one end of the first chamber 211, and the damping shaft 23 and the arc-shaped support surface 11 may not be necessary to achieve a flat cat litter state. In addition, the damping shaft 23 can be integrally formed with the second shaft pin 42, or it can be set independently at any position on the outer side wall of the basin 20, as long as the arc-shaped support surface 11 is set in correspondence with the damping shaft 23.

[0031] Alternatively, in one embodiment, in conjunction with reference to Figure 1 and Figure 2A limiting rod 50 is provided between the base 10 and the basin 20. The limiting rod 50 has a fifth end 51 and a sixth end 52. The fifth end 51 is rotatably connected to the basin 20 via a third pin 43, and the sixth end 52 is rotatably connected to the base 10 via a fourth pin 44. Both the third pin 43 and the fourth pin 44 are parallel to the width direction of the sand trough 21 (basin 20). In this embodiment, all four pins are parallel to each other. Further, the fifth end 51 is provided with a first groove 53 extending along its axial direction. The end of the third pin 43 is limited to the first groove 53 and moves within the first groove 53 as the basin 20 flips, thereby limiting the maximum flipping angle of the basin 20. And / or, the sixth end 52 is provided with a second groove extending along its axial direction (not shown in the figure, but refer to the first groove 53). The end of the fourth pin 44 is limited to the second groove and moves within the second groove as the basin 20 flips, thereby limiting the maximum flipping angle of the basin 20. Understandably, during the flipping process of the basin 20, the limiting rod 50 flips synchronously, but the distance between the third axle pin 43 and the fourth axle pin 44 changes accordingly. Therefore, the distance between the position points of the limiting rod 50 corresponding to the two axle pins also changes synchronously. The limiting rod 50 not only rotates relative to the third axle pin 43 but also slides relative to it. When the third axle pin 43 moves to abut against the inner side wall of the end of the first slide groove 53, the basin 20 can no longer flip, which corresponds to the maximum angle of flipping of the basin 20. The flipping angle limitation of the basin 20 can prevent the basin 20 from flipping too much and spilling all the cat litter, or from flipping too much and directly detaching from the base 10, thereby ensuring the cleanliness and safety of the entire pet toilet. The slide groove can be provided only at one end of the limiting rod 50, or it can be provided at both ends of the limiting rod 50. It should be noted that the end of the limiting rod 50 is provided with a first sliding groove 53 to limit the maximum tilting angle of the basin 20. In other embodiments, an angle limiting structure can be provided at the location of the second shaft pin 42. The maximum tilting angle of the basin 20 can also be limited by the groove and block cooperation mentioned above. In this application, any structure that can limit the maximum tilting angle of the basin 20 should be protected.

[0032] Alternatively, in one embodiment, in conjunction with reference to Figure 1 and Figure 2The upper end face of the base 10 is recessed to form a groove 12. In the use position, the basin 20 is at least partially accommodated within the groove 12, and the end of the basin 20 away from the second chamber 212 abuts against the bottom wall of the groove 12. The other opposite end of the basin 20 is rotatably connected to the inner side wall of the groove 12, causing the bottom wall 214 of the sand trough 21 to slope downward from the second chamber 212 toward the first chamber 211. It can be understood that in this embodiment, the groove 12 is used to create a height difference between the two opposite ends of the basin 20, thereby achieving the inclined state of the bottom wall 214 of the sand trough 21. Here, it is not limited whether the bottom wall 214 of the sand trough 21 is inclined relative to the horizontal plane, nor is it limited whether the bottom wall surface 24 of the basin 20 is inclined relative to the horizontal plane.

[0033] Optionally, in one embodiment, reference is made to... Figure 6 The upper surface 13 of the base 10 is flat, and the bottom wall 214 of the sand trough 21 is inclined relative to the horizontal plane. In the use position, the basin 20 is stacked on the upper surface 13 of the base 10, so that the bottom wall 214 of the sand trough 21 is inclined downward from the second chamber 212 toward the first chamber 211. It can be understood that in this embodiment, the inclined state of the bottom wall 214 of the sand trough 21 is achieved by the inclined setting of the bottom wall 214 of the sand trough 21 itself. Here, whether the bottom wall surface 24 of the basin 20 is inclined relative to the horizontal plane is not limited.

[0034] Optionally, in one embodiment, reference is made to... Figure 7 The upper surface 13 of the base 10 is inclined relative to the horizontal plane, and the bottom wall surface 24 of the basin 20 is also inclined relative to the horizontal plane. In the use position, the basin 20 is stacked on the upper surface 13 of the base 10, and the upper surface 13 of the base 10 is in contact with the bottom wall surface 24 of the basin 20, so that the bottom wall 214 of the sand trough 21 is inclined downward from the second chamber 212 toward the first chamber 211. Here, it is not limited whether the bottom wall 214 of the sand trough 21 is inclined relative to the horizontal plane. In this embodiment, the bottom wall surface 24 of the basin 20 is inclined to create a height difference between the two ends of the basin 20, thereby achieving the inclined state of the bottom wall 214 of the sand trough 21. Here, it is not limited whether the bottom wall 214 of the sand trough 21 is inclined relative to the horizontal plane.

[0035] Optionally, in one embodiment, reference is made to... Figure 1 or Figure 2The pet toilet 1 also includes a waste collection box 60, which is attached to the outer wall of the side where the second chamber 212 of the basin 20 is located. The upper edge of the opening of the waste collection box 60 is no higher than the height of the base 10. In the cleaning position, clumps of litter slide down from the first chamber 211 into the waste collection box 60 along the guide surface 222. The waste collection box 60 is detachably attached to the outside of the basin 20 by means of magnetic attraction, snap-fit, etc., to collect pet excrement for subsequent centralized disposal. In other embodiments, the pet toilet 1 does not need to be equipped with a waste collection box 60. Users can also place cardboard boxes, trash cans, or other garbage containers outside the basin 20 to collect clumps of litter, i.e., pet excrement.

Claims

1. A pet toilet, characterized in that, include: Base; A basin is rotatably connected to one end of the base. A sand trough is provided on the side of the basin facing away from the base. A sieve plate is provided in the sand trough, and the sieve plate divides the sand trough into a first chamber and a second chamber. The first chamber has a passage for the pet to enter and exit. The second chamber is a closed structure except that it is connected to the first chamber through the sieve holes on the sieve plate. A driving component is used to rotate the basin relative to the base, so that the basin can switch between the use position and the cleaning position. In the usage position, the basin is stacked on the base, and the bottom wall of the litter trough slopes downward from the second chamber toward the first chamber, so that the cat litter slides into the first chamber under the action of gravity; in the cleaning position, the basin is flipped so that the bottom wall of the litter trough slopes downward from the first chamber toward the second chamber, so that unclumped litter lumps fall into the second chamber through the sieve holes of the sieve plate, while clumped litter lumps are blocked by the sieve plate because their size is larger than the sieve holes; The sieve plate has a guide surface on the side facing the first chamber. The guide surface is inclined to the depth direction of the sand trough and extends obliquely from the edge of the sieve plate toward the outside of the sand trough. In the cleaning position, the clump of sand slides down along the guide surface and is discharged to the outside of the first chamber.

2. The pet toilet according to claim 1, characterized in that, The driving component includes a pressure rod and a linkage rod that are joined at an angle. The pressure rod has a first end and a second end that are opposite each other, and the linkage rod has a third end and a fourth end that are opposite each other. The first end extends out of the pet toilet for user operation. The second end and the third end are both rotatably connected to the base through a first axle pin. The fourth end is rotatably connected to the basin through a second axle pin. The first axle pin and the second axle pin are parallel to each other. The second end and the third end are provided with a limiting groove and a limiting block, respectively. The end of the limiting block is accommodated in the limiting groove and can rotate relative to the first pivot pin within a preset angle range. In the use position, the limiting block abuts against an inner wall of the limiting groove along the circumference of the first pivot pin, and the included angle between the pressure rod and the linkage rod is a first angle. When the first end is pressed down, the pressure rod first rotates relative to the linkage rod around the first pivot pin to the preset angle, and then the limiting block abuts against another opposite inner wall of the limiting groove. The pressure rod and the linkage rod are linked and then rotate synchronously to drive the basin to flip around the first pivot pin, switching from the use position to the cleaning position. In the cleaning position, the included angle between the pressure rod and the linkage rod is a second angle, which is greater than the first angle.

3. The pet toilet according to claim 2, characterized in that, The number of pressure rods and linkage rods is two each. One pressure rod and one linkage rod form a set of components. The two sets of components are symmetrically arranged on opposite sides of the basin along the axial direction of the first shaft pin. The driving component also includes an operating rod, which is connected between the two first ends and is parallel to the first shaft pin and the second shaft pin.
