Description

Technical Field

[0001] This invention relates to the technical field of pet products, and more particularly to a smart pet toilet. Background Technology

[0002] Existing pet litter boxes, such as the litter box disclosed in Chinese invention patent application CN111802256A entitled "An Intelligent Cat Litter Box," include a self-cleaning compartment and a base. The self-cleaning compartment is rotatably mounted on the base and contains a filter plate. When cleaning litter clumps, the self-cleaning compartment rotates, causing clean litter particles to pass through the filter plate and separate from the litter clumps. When the self-cleaning compartment rotates to the point where the waste outlet is at the bottom, the litter clumps are discharged from the waste outlet. Refilling the litter box involves a litter storage and dispensing module located above and behind the self-cleaning compartment, which adds clean litter. Because the litter storage and dispensing module and the self-cleaning compartment are two separate components, the overall structure of the litter box is relatively large and complex, making assembly inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent pet toilet, which has the advantages of simple structure, reasonable design, small space occupation, and convenient assembly.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: an intelligent pet toilet, including a roller seat, a base, a collection mechanism, a sand replenishment control mechanism, a drive mechanism, and a control module; the collection mechanism is set on the base and located below the roller seat; the roller seat is rotatably set on the base, and a toilet chamber, a sand filter chamber, a sand storage chamber, and a sand replenishment channel are formed inside the roller seat; the sand filter chamber, the sand replenishment channel, and the sand storage chamber are arranged sequentially around the rotation axis of the roller seat around the toilet chamber; the side of the sand filter chamber away from the sand storage chamber has a plurality of filter holes communicating with the toilet chamber, and the side of the sand filter chamber close to the sand storage chamber is connected to the sand storage chamber through the sand replenishment channel; a waste discharge port communicating with the outer peripheral surface of the roller seat is formed on the toilet chamber, the waste discharge port is located between the sand filter chamber and the sand storage chamber, and the waste discharge port can be driven by the roller seat to face the collection mechanism; the sand replenishment control mechanism can switch between blocking the sand replenishment channel and opening the sand replenishment channel according to the movement state of the roller seat; the drive mechanism is used to drive the roller seat to rotate; the control module is electrically connected to the drive mechanism.

[0005] Working principle of the invention:

[0006] In standby mode, the filter sand bin and sand storage bin are located on the left and right sides of the toilet compartment, respectively, while the waste discharge port and sand replenishment channel are located on the upper side of the toilet compartment. The sand replenishment control mechanism is in the state of blocking the sand replenishment channel. During sand cleaning, the roller seat is driven by the drive mechanism to rotate forward, causing the filter sand bin to move downward around the toilet compartment and the sand storage bin to move upward around the toilet compartment. During this process, clean sand particles in the toilet compartment enter the filter sand bin through the filter holes. When the waste discharge port moves to the lower side of the toilet compartment and faces the collection mechanism, the roller seat stops rotating, and the sand particles blocked by the filter holes and remaining in the toilet compartment fall from the waste discharge port to the collection mechanism for collection. After the sand particles are discharged, the roller seat is driven by the drive mechanism to rotate in the opposite direction, causing the filter sand bin to move downward around the toilet compartment and the sand storage bin to move upward around the toilet compartment. This causes the sand particles in the filter sand bin to return to the toilet compartment through the filter holes until the waste discharge port moves to the upper side of the toilet compartment, at which point the smart pet toilet returns to standby mode. During the rotation of the roller seat, when the filter sand bin moves below the sand storage bin, the sand replenishment control mechanism opens the sand replenishment channel. Reserve sand particles in the sand storage bin fall through the replenishment channel into the filter sand bin to replenish the sand. After replenishment, the sand replenishment control mechanism closes the replenishment channel again. By incorporating a sand storage bin, sand replenishment channel, and sand replenishment control mechanism into the roller seat, the roller seat can automatically replenish the remaining sand each time it cleans sand blocks, eliminating the need for manual replenishment and making it more convenient to use. Furthermore, since the sand particles in the sand storage bin fall into the filter sand bin by their own weight, when the filter sand bin is full, sand particles in the storage bin will have difficulty falling into the filter sand bin. This allows for automatic control of the sand level in the filter sand bin, eliminating the need for additional monitoring components and reducing production costs. In addition, the automatic sand replenishment component is integrated with the roller seat, making the structure of this smart pet toilet more compact and simple, occupying less space, and easier to assemble.

[0007] Furthermore, in the aforementioned intelligent pet toilet, the litter replenishment control mechanism includes a control door, a litter replenishment drive shaft, and a litter replenishment drive rack. The control door is rotatably mounted in the litter replenishment channel via the litter replenishment drive shaft. The control door can switch between a closed state (blocking the litter replenishment channel) and an open state (opening the litter replenishment channel) by rotation, and the control door has a tendency to switch to the closed state. The litter replenishment drive rack is mounted and fixed on the base, and the litter replenishment drive rack is an arc-shaped structure arranged around the rotation axis of the roller seat. One end of the litter replenishment drive shaft can be driven by the roller seat to combine with the litter replenishment drive rack for transmission connection. In the combined state, the litter replenishment drive shaft can be driven to rotate by the relatively moving litter replenishment drive rack, so that the control door switches to the open state.

[0008] Furthermore, in the aforementioned intelligent pet toilet, the litter replenishment control mechanism also includes a transmission component, which is mounted on the roller seat and is connected to the litter replenishment drive shaft. The transmission component can only drive the litter replenishment drive shaft to rotate in a single direction. The transmission component can be driven by the roller seat and connected to the litter replenishment drive rack for transmission.

[0009] Furthermore, as described above, the intelligent pet toilet also includes a waste discharge control mechanism, which includes a waste discharge door, a waste discharge drive shaft, and a waste discharge drive rack. The waste discharge door is rotatably mounted on the waste discharge opening via the waste discharge drive shaft. The waste discharge door can switch between a closed state (covering the waste discharge opening) and an open state (opening the waste discharge opening) by rotation, and the waste discharge door has a tendency to switch to the closed state. The waste discharge drive rack is mounted and fixed on the base, and the waste discharge drive rack is an arc-shaped structure arranged around the rotation axis of the roller seat. One end of the waste discharge drive shaft can be driven by the roller seat to combine with the waste discharge drive rack for transmission connection. In the combined state, the waste discharge drive shaft can be driven to rotate by the relatively moving waste discharge drive rack, so that the waste discharge door switches to the open state.

[0010] Furthermore, another embodiment of the intelligent pet toilet described above also includes a waste discharge control mechanism. This mechanism includes a waste discharge door, a waste discharge actuating component, and a waste discharge drive stop. The waste discharge door is rotatably mounted on the waste discharge opening. The door can switch between a closed state (blocking the waste discharge opening) and an open state (opening the waste discharge opening) by rotation, and the door has a tendency to switch to the closed state. The waste discharge drive stop is fixedly mounted on the base. The waste discharge actuating component is rotatably mounted on the roller seat. One end of the actuating component is a actuating end, and the other end is a transmission end. The actuating end of the actuating component is connected to the waste discharge door via a transmission connection. The transmission end of the actuating component can be driven by the roller seat and pressed by the waste discharge drive stop, causing the actuating component to rotate and move the waste discharge door to the open state.

[0011] Furthermore, in the aforementioned intelligent pet toilet, the waste discharge control mechanism further includes a toggle arm. One end of the toggle arm is rotatably connected to the roller seat. The rotation axis of the toggle arm is perpendicular to the rotation axis of the waste discharge actuating component. The transmission end of the waste discharge actuating component abuts against the side of the toggle arm facing the roller seat, so that the other end of the toggle arm has a tendency to move away from the direction of the roller seat. The toggle arm is driven by the roller seat and can be squeezed by the waste discharge drive stop and swing towards the roller seat, so that the waste discharge actuating component is squeezed and rotated by the toggle arm.

[0012] Furthermore, in the aforementioned intelligent pet toilet, a locking protrusion is formed on the roller seat. The locking protrusion is a cylindrical boss or an annular structure. The central axis of the locking protrusion is collinear with the rotation axis of the roller seat. A locking flange is formed on the circumferential surface of the locking protrusion. It also includes a locking disc, which is rotatably mounted on the base. An insert recess and a locking groove are formed on the circumferential surface of the locking disc. The insert recess and the locking groove are arranged sequentially around the rotation axis of the locking disc. The insert recess is connected to one end face of the locking disc, and one end of the locking groove is connected to the insert recess. The locking disc can be switched between an unlocked state where the locking flange is engaged in the insert recess and a locked state where the locking flange is engaged in the locking groove by rotation.

[0013] Furthermore, in another embodiment of the aforementioned intelligent pet toilet, a locking protrusion is formed on the roller seat. The locking protrusion is a cylindrical boss or an annular structure. The central axis of the locking protrusion is collinear with the rotation axis of the roller seat. A locking flange is formed on the circumferential surface of the locking protrusion. The device also includes a locking assembly, which comprises a locking seat and a clamping member. The locking seat is fixedly mounted on the base and has a clamping part with an arc-shaped structure. The clamping member is slidably mounted on the locking seat and has an arc-shaped structure. The clamping member slides towards the clamping part to cooperate with the clamping part in clamping and positioning the circumferential surface of the locking protrusion. The locking flange is used to prevent the clamping part and clamping member from disengaging from the locking protrusion when in a clamped state.

[0014] Furthermore, in the aforementioned intelligent pet toilet, the locking assembly further includes a swing handle and a transmission connector; the swing handle is rotatably mounted on the locking seat; one end of the transmission connector is rotatably connected to the swing handle, and the other end of the transmission connector is rotatably connected to the clamping member and slidably mounted on the locking seat, so that the swing handle can rotate to drive the clamping member to slide closer to or away from the clamping part.

[0015] Furthermore, in the aforementioned intelligent pet toilet, a locking hole is formed on the swing handle; a locking slide is formed on the locking seat, and a clamping protrusion and a locking channel are formed on the locking slide; a locking slider is slidably disposed in the locking slide, and a clamping recess is formed on the locking slider; a locking pin is slidably disposed in the locking channel, and a locking elastic member is compressed between the locking pin and the channel opening away from the locking slide, so that the locking pin protrudes from the locking slide when no external force is applied; the locking slider slides so that its clamping recess and clamping protrusion are nested together, and the locking pin is squeezed by the locking slider and slides away from the locking slide, so that one end of the locking pin extends from the channel opening away from the locking slide and is inserted into the locking hole of the swing handle for locking. When the locking pin is in the locked state, the locking pin and the clamping protrusion cooperate to clamp and position the locking slider.

[0016] Furthermore, in the aforementioned intelligent pet toilet, the roller seat includes a shell, a cover plate, and a litter tray. The shell is a cylindrical structure with one end open. The inner cavity of the shell forms the filter sand chamber, the litter storage chamber, the litter replenishment channel, and the waste discharge port. The litter tray is detachably connected to the shell and slides into the inner cavity of the shell from the opening, such that the litter tray, the filter sand chamber, the litter replenishment channel, and the litter storage chamber are arranged sequentially around the axis of the shell. The cover plate is detachably installed on the opening of the shell to cover it, such that the cover plate, the litter tray, and the inner wall of the shell together form the toilet compartment.

[0017] Furthermore, as described above, the intelligent pet toilet also includes a magnetic encoder, which includes a magnetic sensor and a disk; the disk is mounted on the roller seat, and the central axis of the disk is collinear with the rotation axis of the roller seat; the magnetic sensor is mounted on the base, with the sensing end of the magnetic sensor facing one side of the disk, and the magnetic sensor is used to monitor the rotation angle of the disk, and the magnetic sensor is electrically connected to the control module.

[0018] Furthermore, as described above, the intelligent pet toilet also includes a support foot and a weight monitoring component; the weight monitoring component includes a base plate, a sensing spring, and a monitoring module. The base plate is mounted and fixed on the bottom surface of the base, and a central hole is formed in the middle of the base plate. The sensing spring is connected to the inner wall of the central hole of the base plate. The monitoring module is used to monitor the deformation state of the sensing spring, and the monitoring module is electrically connected to the control module; the support foot is located below the weight monitoring component, and a trigger protrusion is formed on the end face of the support foot facing the weight monitoring component. The trigger protrusion abuts against the sensing spring of the weight monitoring component.

[0019] Furthermore, as described above, in a smart pet toilet, the toilet compartment has an entrance / exit on its side wall that communicates with the outer periphery of the roller seat; it also includes a corridor seat located beside the roller seat, and a corridor passage is formed inside the corridor seat; in standby mode, the entrance / exit of the roller seat is connected to one of the passage openings of the corridor seat.

[0020] Furthermore, in the aforementioned intelligent pet toilet, a locking hook is formed on the corridor seat. The locking hook includes a hook head and a connecting rod. One end of the connecting rod is connected to the corridor seat, and the other end of the connecting rod forms the hook head. The cross-sectional diameter of the hook head is larger than the cross-sectional diameter of the connecting rod. An installation hole is formed on the base. The outline of the installation hole includes a circular hole portion and a connecting section. One end of the connecting section communicates with the circular hole portion, and the diameter of the circular hole portion is larger than the width of the connecting section. After the hook head of the locking hook passes through the installation hole from the circular hole portion, the connecting rod slides along the connecting section to the end of the connecting section away from the circular hole portion, so that the locking hook and the installation hole engage with each other, thereby connecting and fixing the corridor seat and the base together.

[0021] Furthermore, in the aforementioned intelligent pet toilet, the inner wall of the litter storage compartment has a litter filling port and a limiting groove; the litter filling port connects to the outer circumferential surface of the roller seat, and a litter filling door is rotatably installed on the litter filling port; the limiting groove has an arc structure, and a first snap-fit ​​protrusion is formed on the bottom of the limiting groove; a second snap-fit ​​protrusion is formed on the litter filling door, and the second snap-fit ​​protrusion is slidably embedded in the limiting groove; the litter filling door can be rotated to cover the litter filling port and allow the second snap-fit ​​protrusion to slide past the first snap-fit ​​protrusion, so that the second snap-fit ​​protrusion and the first snap-fit ​​protrusion engage with each other to lock the litter filling door.

[0022] Furthermore, in the aforementioned intelligent pet toilet, the inner wall of the litter storage compartment is provided with a first suction member, and the litter replenishment door is provided with a second suction member. When the litter replenishment door is in the state of covering the litter replenishment opening, the first suction member and the second suction member engage with each other to lock the litter replenishment door.

[0023] The technical solution of the present invention has the following beneficial effects: by setting a sand storage bin, a sand replenishment channel and a sand replenishment control mechanism in the roller seat, the roller seat can automatically replenish the remaining sand particles each time it cleans sand blocks, eliminating the need for manual sand replenishment and making it more convenient to use; moreover, the components for automatic sand replenishment are integrated with the roller seat, making the structure of this intelligent pet toilet more compact and simple, occupying less space and making assembly more convenient.

Detailed Implementation

[0053] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0054] Example 1

[0055] like Figures 1 to 18An intelligent pet toilet includes a roller seat 2, a base 1, a collection mechanism 30, a litter replenishment control mechanism 3, a drive mechanism 5, and a control module 40. The collection mechanism 30 is mounted on the base 1 and located below the roller seat 2. The roller seat 2 has a cylindrical structure, with one end being the inlet / outlet and the other end being the mounting end. The roller seat 2 is rotatably mounted on the base 1, and its rotation axis is set along its central axis. The roller seat 2 contains a toilet chamber 21, a sand filter chamber 22, a litter storage chamber 23, and a litter replenishment channel 24. The sand filter chamber 22, litter replenishment channel 24, and litter storage chamber 23 are arranged sequentially around the rotation axis of the roller seat 2 on the periphery of the toilet chamber 21. The side of the sand filter chamber 22 furthest from the litter storage chamber 23 has several filter holes 221 communicating with the toilet chamber 21. The side of the sand filter chamber 22 closest to the litter storage chamber 23 is connected to the litter storage chamber 23 via the litter replenishment channel 24. The toilet chamber 21 has a waste outlet communicating with the outer circumference of the roller seat 2. The waste discharge port is located between the filter sand bin 22 and the sand storage bin 23. The waste discharge port can be driven by the roller seat 2 to be directly opposite the collection mechanism 30. The toilet bin 21 also has a first inlet 211 that communicates with the inlet and outlet end face of the roller seat 2. A door panel 213 is rotatably installed on the first inlet 211. The sand replenishment control mechanism 3 can switch between blocking the sand replenishment channel 24 and opening the sand replenishment channel 24 according to the movement state of the roller seat 2. The drive mechanism 5 includes a drive motor 53, a drive gear 51 and a driven gear 52. The drive gear 51 is rotatably mounted on the base 1. The driven gear 52 is fixedly mounted on the mounting end face of the roller seat 2. The central axis of the driven gear 52 is collinear with the rotation axis of the roller seat 2. The driven gear 52 and the drive gear 51 are meshed in an externally tangential manner. The drive motor 53 is mounted on the base 1 and is used to drive the drive gear 51 to rotate. The control module 40 is electrically connected to the drive motor 53.

[0056] like Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 15As shown, the sand replenishment control mechanism 3 includes a control door 31, a sand replenishment drive shaft 32, a sand replenishment reset component (not shown in the attached drawing), and a sand replenishment drive rack 33. The control door 31 is rotatably mounted in the sand replenishment channel 24 via the sand replenishment drive shaft 32. The rotation axis of the control door 31 is parallel to the rotation axis of the roller seat 2. The control door 31 can switch between a closed state (blocking the sand replenishment channel 24) and an open state (opening the sand replenishment channel 24) by rotation. The control door 31 is equipped with the sand replenishment reset component, which is a torsion spring. Under the action of the sand replenishment reset component, the control door 31... The control door 31 has a tendency to switch to the closed state; the sand replenishment drive rack 33 is installed and fixed on the base 1, and the sand replenishment drive rack 33 is an arc-shaped structure arranged around the rotation axis of the roller seat 2; one end of the sand replenishment drive shaft 32 can be driven by the roller seat 2 to combine with the sand replenishment drive rack 33 for transmission connection. In the combined state, the sand replenishment drive shaft 32 can be driven to rotate by the relatively moving sand replenishment drive rack 33, so that the control door 31 switches to the open state; when the sand replenishment drive shaft 32 is disengaged from the sand replenishment drive rack 33, the control door 31 is reset to the closed state under the action of the sand replenishment reset component. The sand replenishment control mechanism 3 controls the on / off state of the sand replenishment channel 24 through mechanical connection. Since the sand replenishment control mechanism 3 does not need to set up expensive electrical components, the production cost is reduced, and the roller seat 2 and the base 1 do not need to reserve wiring space for the sand replenishment control mechanism 3, making the structure of the sand replenishment control mechanism 3 more compact.

[0057] like Figure 5 , Figure 8 , Figure 9 and Figure 18As shown, the sand-filling drive shaft 32 is provided with a first drive shaft 34 and a second drive shaft 35 sequentially along its axial direction. The first drive shaft 34 is coaxially and fixedly connected to the sand-filling drive shaft 32, and the second drive shaft 35 is rotatably mounted on the sand-filling drive shaft 32. The second drive shaft 35 is located outside the first drive shaft 34 and protrudes from the mounting end face of the roller seat 2. The first drive shaft 34 and the second drive shaft 35 have a tendency to move closer to each other. A first drive protrusion is formed on the end face of the first drive shaft 34 facing the second drive shaft 35. The first drive protrusion has a ramp structure, and the ramp travel path of the first drive protrusion is arranged around the axis of the first drive shaft 34. The second drive shaft 35 faces the first drive shaft 34. A second transmission protrusion is formed on the end face of 34. The second transmission protrusion has a sloping structure. The sloping travel path of the second transmission protrusion is arranged around the axis of the second transmission shaft 35. The sloping direction of the second transmission protrusion is opposite to that of the first transmission protrusion, so that when the second transmission protrusion rotates in the forward direction, its sloping surface slides into contact with the sloping surface of the first transmission protrusion, so that the first transmission shaft 34 and the second transmission shaft 35 cannot drive each other at this time. When the second transmission protrusion rotates in the reverse direction, its sloping top abuts against the sloping top of the first transmission protrusion, so that the first transmission shaft 34 and the second transmission shaft 35 can drive each other at this time. The second transmission shaft 35 can be driven by the roller seat 2 to engage with the sand filling drive rack 33. When the roller seat 2 rotates forward, causing the second drive shaft 35 to combine with the sand-filling drive rack 33, the second drive shaft 35 can be driven to rotate forward by the relatively moving sand-filling drive rack 33. At this time, the second drive shaft 35 cannot drive the first drive shaft 34 to rotate, and the control door 31 remains closed. When the roller seat 2 rotates in the reverse direction, causing the second drive shaft 35 to combine with the sand-filling drive rack 33, the second drive shaft 35 can be driven to rotate in the reverse direction by the relatively moving sand-filling drive rack 33. At this time, the second drive shaft 35 can drive the first drive shaft 34 to rotate, thereby causing the sand-filling drive shaft 32 to rotate by the first drive shaft 34, and thus the control door 31 switches to the open state. Through this design, the sand-filling drive shaft 32 can only be driven to rotate by the sand-filling drive rack 33 to open the control door 31 when the roller seat 2 rotates in the reverse direction. This ensures that the sand-filling drive rack 33 can only drive the sand-filling drive shaft 32 to rotate in a single direction, thus fixing the opening direction of the control door 31 to a single direction. This allows for the installation of features such as... Figure 7 The limiting structure 241 shown restricts the rotation range of the control door 31 to achieve the door closing position, making the transmission structure of the control door 31 simpler and more reasonable.

[0058] The working principle of this embodiment:

[0059] In standby mode, the filter sand chamber 22 and the sand storage chamber 23 are located on the left and right sides of the toilet chamber 21, respectively. The waste discharge port and the sand replenishment channel 24 are located directly above the toilet chamber 21, and the sand replenishment control mechanism 3 is in the state of blocking the sand replenishment channel 24. During sand block cleaning, the roller seat 2 is driven by the drive mechanism 5 to rotate forward, causing the filter sand chamber 22 to move downward around the toilet chamber 21 and the sand storage chamber 23 to move upward around the toilet chamber 21. During this process, clean sand particles in the toilet chamber 21 enter the filter sand chamber 22 through the filter holes 221. The second drive shaft 35 is driven by the roller seat 2 to the position of the sand replenishment drive rack 33 and engages with it. The second drive shaft 35 is driven by the relatively moving sand replenishment drive rack 33 to rotate forward. When the second drive shaft 35 cannot drive the first drive shaft 34 to rotate, the control door 31 remains in a state of blocking the sand replenishment channel 24. When the waste discharge port is driven by the roller seat 2 to move to the lower side of the toilet chamber 21 and face the collection mechanism 30, the roller seat 2 stops rotating, and the sand blocks blocked by the filter holes 221 fall from the waste discharge port into the collection mechanism 30 for collection. After the sand blocks are discharged, the roller seat 2 is driven by the drive mechanism 5 to rotate in the opposite direction, causing the sand filter chamber 22 to move downward. The toilet chamber 21 moves in a circular motion, while the sand storage chamber 23 moves upwards around the toilet chamber 21. During this process, the second drive shaft 35 is driven by the roller seat 2 to the position of the sand replenishment drive rack 33 and engages with it. The second drive shaft 35 is driven to rotate in the opposite direction by the relatively moving sand replenishment drive rack 33. At this time, the second drive shaft 35 can drive the first drive shaft 34 to rotate, so that the sand replenishment drive shaft 32 can be driven to rotate by the first drive shaft 34, thereby causing the control door 31 to be opened by the sand replenishment drive shaft 32. The sand channel 24 allows spare sand particles in the sand storage bin 23 to fall into the sand filter bin 22 to replenish sand particles until the second drive shaft 35 disengages from the sand replenishment drive rack 33. The control door 31 is then reset to the state of blocking the sand replenishment channel 24 under the action of the sand replenishment reset component. The roller seat 2 continues to rotate, causing the sand particles in the sand filter bin 22 to return to the toilet bin 21 through the filter holes 221 until the waste outlet moves to the top of the toilet bin 21. The smart pet toilet then returns to the standby state. By incorporating a sand storage bin 23, a sand replenishment channel 24, and a sand replenishment control mechanism 3 into the roller base 2, the roller base 2 can automatically replenish the remaining sand particles each time it cleans up sand blocks, eliminating the need for manual sand replenishment and making it more convenient to use. Furthermore, since the sand particles in the sand storage bin 23 fall into the filter sand bin 22 by their own weight for replenishment, when the filter sand bin 22 has sufficient sand, the sand particles in the sand storage bin 23 will have difficulty falling into the filter sand bin 22. This allows for automatic control of the sand volume in the filter sand bin 22, eliminating the need for additional monitoring components and reducing production costs. In addition, since the automatic sand replenishment component is integrated with the roller base 2, the structure of this smart pet toilet is more compact and simple, occupying less space and making assembly easier.

[0060] like Figure 17 As shown, the travel path of the sand replenishment channel 24 is a curved structure, so that the two channel openings of the sand replenishment channel 24 are arranged along the axial direction of the roller seat 2. With this structure, the speed at which sand particles fall from the sand storage bin 23 to the filter sand bin 22 can be slowed down, thereby controlling the amount of sand replenished in a single sand replenishment action.

[0061] like Figure 1 , Figure 2 , Figure 5 , Figure 8 , Figure 9 and Figure 15As shown, this embodiment also includes a waste discharge control mechanism 4, which includes a waste discharge door 41, a waste discharge drive shaft 42, a waste discharge transmission shaft 43, a waste discharge reset component (not shown in the drawings), and a waste discharge drive rack 44. The waste discharge door 41 is rotatably mounted on the waste discharge port via the waste discharge drive shaft 42. The rotation axis of the waste discharge door 41 is parallel to the rotation axis of the roller seat 2. The waste discharge door 41 can switch between a closed state (blocking the waste discharge port) and an open state (opening the waste discharge port) by rotation. The waste discharge door 41 is provided with the waste discharge reset component, which is a torsion spring. Under the action of the waste discharge reset component, the waste discharge door 41 has a tendency to switch to the closed state. The waste discharge transmission shaft 43 is rotatably mounted on the roller seat 2. The rotation axis of the waste discharge transmission shaft 43 is parallel to the rotation axis of the waste discharge drive shaft 42, and the rotation of the waste discharge transmission shaft 43... The axis is located on the side of the rotation axis of the waste discharge drive shaft 42 that is closer to the rotation axis of the roller seat 2. The waste discharge transmission shaft 43 is meshed with one end of the waste discharge drive shaft 42, and the waste discharge transmission shaft 43 is located outside the waste discharge drive shaft 42 and protrudes from the mounting end face of the roller seat 2. The waste discharge drive rack 44 is installed and fixed on the base 1. The waste discharge drive rack 44 is an arc-shaped structure arranged around the rotation axis of the roller seat 2. The waste discharge transmission shaft 43 can be driven by the roller seat 2 to mesh with the waste discharge drive rack 44. In the combined state, the waste discharge transmission shaft 43 can be driven to rotate by the relatively moving waste discharge drive rack 44, so that the waste discharge transmission shaft 43 can be driven to rotate by the waste discharge drive rack 44 and drive the waste discharge door 41 to switch to the open state. When the waste discharge transmission shaft 43 is disengaged from the waste discharge drive rack 44, the waste discharge door 41 is reset to the closed state under the action of the waste discharge reset component. The waste discharge control mechanism 4 controls the opening and closing of the waste discharge port through a mechanical connection. Since the waste discharge control mechanism 4 does not require expensive electrical components, the production cost is reduced, and the roller seat 2 and base 1 do not need to reserve wiring space for the waste discharge control mechanism 4, making the structure of the waste discharge control mechanism 4 more compact. In addition, in order to make the outer surface of the roller seat 2 more flat and aesthetically pleasing, the rotation axis of the waste discharge door 41 needs to be set closer to the outer circumference of the roller seat 2. By adding a waste discharge transmission shaft 43, the base 1 does not need to reserve transmission space for the waste discharge drive shaft 42. As a result, the outer surface of the base 1 can be more easily designed to have a smooth transition with the circumferential surface of the roller seat 2, making the connection structure between the base 1 and the roller seat 2 more compact and aesthetically pleasing.

[0062] like Figure 8 and Figure 9As shown, a first limiting protrusion 12 is formed on the base 1, and a second limiting protrusion 25 is formed on the mounting end face of the roller seat 2. When the roller seat 2 rotates to the point where its waste discharge port is directly opposite the collection mechanism 30, the first limiting protrusion 12 and the second limiting protrusion 25 can abut against each other to prevent the roller seat 2 from rotating too much, and can also prevent the waste discharge transmission shaft 43 from disengaging from the waste discharge drive rack 44 during the waste discharge operation, thus preventing the waste discharge door 41 from being closed.

[0063] like Figure 8 , Figure 9 and Figure 14 As shown, the driven gear 52 has a locking protrusion 26 on the side facing away from the roller seat 2. The locking protrusion 26 is an annular structure arranged around the central axis of the driven gear 52, and a locking flange 261 is formed on the outer peripheral surface of the locking protrusion 26. It also includes a locking disc 6, which is rotatably mounted on the base 1. The circumferential surface of the locking disc 6 has an insert recess 61 and a locking groove 62. The insert recess 61 and the locking groove 62 are arranged sequentially around the rotation axis of the locking disc 6. The insert recess 61 is connected to one end face of the locking disc 6, and one end of the locking groove 62 is connected to the insert recess 61. The locking disc 6 can be switched between an unlocked state in which the locking flange 261 is engaged in the insert recess 61 and a locked state in which the locking flange 261 is engaged in the locking groove 62 by rotation. When the locking flange 261 is embedded in the mounting recess 61, the roller seat 2 can be disassembled from the base 1 because the locking flange 261 and the locking disc 6 do not contact each other. When the locking flange 261 is embedded in the mounting groove 62, the locking flange 261 and the mounting groove 62 engage with each other, so that the roller seat 2 and the base 1 engage with each other and are fixed. This design makes the installation and disassembly of the roller seat 2 more convenient.

[0064] like Figure 5 , Figure 8 , Figure 9 and Figure 15 As shown, this embodiment also includes a magnetic encoder 7, which includes a magnetic sensor 71 and a disk 72. The disk 72 is mounted on the driven gear 52 on the roller seat 2, and the central axis of the disk 72 is collinear with the rotation axis of the roller seat 2. The magnetic sensor 71 is mounted on the base 1, with its sensing end facing one side of the disk 72. The magnetic sensor 71 is used to monitor the rotation angle of the disk 72 and is electrically connected to the control module 40. The magnetic sensor 71 can monitor the angle change of the disk 72 by monitoring the change in the magnetic field of the disk 72, thereby enabling the magnetic encoder 7 to monitor the rotation angle of the roller seat 2. This allows the control module 40 to accurately control the rotation range of the roller seat 2 by controlling the operation of the drive mechanism 5, thus improving the working accuracy of this intelligent pet toilet.

[0065] like Figure 15 and Figure 16 As shown, this embodiment also includes four support feet 8 and four weight monitoring components 9; each weight monitoring component 9 includes a base plate 91, a sensing spring 92, and a monitoring module 93. The base plate 91 is mounted and fixed on the bottom surface of the base 1. A central hole is formed in the middle of the base plate 91, and the sensing spring 92 is connected to the inner wall of the central hole of the base plate 91. The monitoring module 93 is used to monitor the resistance change state caused by the deformation of the sensing spring 92. The monitoring module 93 is electrically connected to the control module 40; the four support feet 8 respectively Arranged at the four corners of the base 1, a support foot 8 corresponds to a weight monitoring component 9. The support foot 8 is located below the weight monitoring component 9. A trigger protrusion 81 is formed on the end face of the support foot 8 facing the weight monitoring component 9. Three positioning protrusions 82 are formed on the trigger protrusion 81. The trigger protrusion 81 abuts against the sensing spring 92 of the weight monitoring component 9. The three positioning protrusions 82 are respectively located on the three sides of the sensing spring 92 that are not connected to the base plate 91, thereby achieving relative positioning between the sensing spring 92 and the support foot 8. By adding the support foot 8 and the weight monitoring component 9, the control module 40 can know whether a pet has entered or exited the smart pet toilet based on the changes in weight parameters monitored by the weight monitoring component 9. When the control module 40 detects that a pet has left the smart pet toilet, the control module 40 controls the drive mechanism 5 to work and automatically clean the litter in the toilet compartment 21, thus increasing the degree of automation.

[0066] like Figure 1 , Figure 4 , Figure 5 , Figure 10 and Figure 11As shown, the toilet compartment 21 has a second inlet 212 on its side wall that communicates with the outer circumferential surface of the roller seat 2. The second inlet 212 and the sand storage compartment 23 are arranged along the axial direction of the roller seat 2. It also includes a corridor seat 20, located beside the roller seat 2. The corridor seat 20 has a third inlet 201 and a fourth inlet 202 communicating with its inner cavity. The third inlet 201 and the fourth inlet 202 are respectively located on two adjacent vertical surfaces of the corridor seat 20. The corridor seat 20 is equipped with a support mesh plate 204, a guide plate 205, and a collection box 206. The third entrance 201 and the fourth entrance 202 are connected by a supporting mesh plate 204, so that the third entrance 201, the fourth entrance 202, and the supporting mesh plate 204 of the corridor seat 20 together form a corridor passage. The guide plate 205 is located below the supporting mesh plate 204 and is inclined. The collection box 206 is located below the lower end of the guide plate 205 and can be detached from the corridor seat 20 by sliding. In standby mode, the second entrance 212 of the roller seat 2 is connected to the third entrance 201 of the corridor passage of the corridor seat 20. The corridor passage is used for pets to leave the toilet chamber 21. The supporting mesh plate 204 cleans the sand particles adhering to the pet's paws. The sand particles fall from the mesh of the supporting mesh plate 204 onto the guide plate 205 and slide down the guide plate 205 into the collection box 206 for collection and storage, thereby preventing the pet from polluting the surrounding ground when leaving this smart pet toilet.

[0067] like Figure 10 and Figure 11 As shown, four locking hooks 203 are formed on the side of the corridor seat 20 facing the base 1. Each locking hook 203 includes a hook head and a connecting rod. One end of the connecting rod is connected to the corridor seat 20, and the other end of the connecting rod forms the hook head. The cross-sectional diameter of the hook head is larger than the cross-sectional diameter of the connecting rod. Four mounting holes 11 are formed on the base 1. The outline of each mounting hole 11 includes a circular hole and a connecting section. One end of the connecting section communicates with the circular hole, and the diameter of the circular hole is larger than the width of the connecting section. One locking hook 203 corresponds to one mounting hole 11. After the hook head of the locking hook 203 passes through the mounting hole 11 from the circular hole, the connecting rod slides along the connecting section to the end of the connecting section away from the circular hole, so that the locking hook 203 and the mounting hole 11 are engaged with each other, thereby connecting and fixing the corridor seat 20 to the base 1. This structure makes the installation and disassembly of the corridor seat 20 more convenient.

[0068] like Figure 12 and Figure 13As shown, a sand filling port 231 and a limiting groove 232 are formed on the inner wall of the sand storage bin 23; the sand filling port 231 is connected to the outer peripheral surface of the roller seat 2, and a sand filling door 10 is rotatably installed on the sand filling port 231; the limiting groove 232 has an arc structure, one end of the limiting groove 232 is connected to the sand filling port 231, and a first snap-fit ​​protrusion 233 is formed on the bottom of the limiting groove 232, the first snap-fit ​​protrusion 233 is set near the end of the limiting groove 232 away from the sand filling port 231; a second snap-fit ​​protrusion 101 is formed on the sand filling door 10, and the second snap-fit ​​protrusion 101 is slidably embedded in the limiting groove 232; The sand filling door 10 can be rotated to switch between a closed state (covering the sand filling opening 231) and an open state (opening the sand filling opening 231). The second latching protrusion 101 can be driven by the sand filling door 10 to slide along the limiting slide groove 232. During the process of switching the sand filling door 10 to the closed state, the second latching protrusion 101 slides past the first latching protrusion 233, so that the second latching protrusion 101 and the first latching protrusion 233 engage with each other to lock the sand filling door 10, preventing the sand filling door 10 from being opened without external force, thereby preventing the sand filling door 10 from being opened due to sand particles during the cleaning of the smart pet toilet.

[0069] like Figure 12 and Figure 13 As shown, the inner wall of the sand storage bin 23 is provided with a first suction member 234, which is a metal part; the sand replenishment door 10 is provided with a second suction member 102, which is a magnet; when the sand replenishment door 10 is in the closed state of covering the sand replenishment port 231, the first suction member 234 and the second suction member 102 attract each other to lock the sand replenishment door 10, thereby further improving the connection structure strength between the sand replenishment door 10 and the roller seat 2, and preventing the sand replenishment door 10 from being opened due to sand particle compression.

[0070] like Figure 5 and Figure 15As shown, the collection mechanism 30 includes a base 301, a collection chamber 302, a crushing component 303, a crushing motor 304, a water pump 305, and a first terminal 306. The base 301 is detachably mounted on the base 1. The collection chamber 302 is mounted on the base 301. The roller seat 2 can be rotated so that its waste outlet is directly opposite the opening of the collection chamber 302, so that sand blocks are collected in the collection chamber 302. The collection chamber 302 is provided with a sewage outlet and a water inlet. The sewage outlet is connected to an external sewer, and the water inlet is connected to one end of the water pump 305 through a pipe. The other end of the water pump 305 is connected to an external tap water pipe through a pipe. 305 is used to fill the collection chamber 302 with water; the agitator 303 is rotatably disposed inside the collection chamber 302 to agitate the sand blocks inside the collection chamber 302, so that the sand blocks and water are mixed into slurry and discharged from the drain port of the collection chamber 302; the agitator motor 304 is used to drive the agitator 303 to rotate; the first terminal 306 is electrically connected to the agitator motor 304 and the water pump 305; a second terminal is installed on the base 1, and the second terminal is electrically connected to the control module 40. The second terminal can be connected to the first terminal 306, so that the control module 40 can control the operation of the agitator motor 304 and the water pump 305. By setting the first terminal 306 and the second terminal, the collection mechanism 30 can be disassembled and installed without the need for manual reconnection of cables, making the installation operation more convenient.

[0071] Example 2

[0072] like Figures 19 to 27This is an example of an intelligent pet toilet in Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is that the waste disposal control mechanism 4 includes a waste disposal door 41, a waste disposal reset component, a waste disposal actuating component 45, a waste disposal drive stop 46, and a actuating swing arm 47. The waste disposal door 41 is rotatably mounted on the waste disposal opening. The waste disposal door 41 can switch between a closed state (blocking the waste disposal opening) and an open state (opening the waste disposal opening) by rotation. The waste disposal door 41 is equipped with the waste disposal reset component, which is a torsion spring. Under the action of the waste disposal reset component, the waste disposal door 41 has… The waste discharge door 41 has a transmission slide 411 formed on it to switch to the closed state. The waste discharge actuating member 45 is rotatably mounted on the roller seat 2. One end of the waste discharge actuating member 45 is the actuating end, and the other end is the transmission end. The actuating end of the waste discharge actuating member 45 is inserted into the transmission slide 411 of the waste discharge door 41. The waste discharge actuating member 45 can rotate to make the actuating end move in the radial direction of the cross-section of the roller seat 2, thereby actuating the waste discharge door 41. One end of the actuating swing arm 47 is rotatably connected to the roller seat 2. Next, the rotation axis of the actuating arm 47 is perpendicular to the rotation axis of the waste discharge actuating member 45, so that the rotation axis of the actuating arm 47 remains perpendicular to the movement direction of the roller seat 2. The transmission end of the waste discharge actuating member 45 abuts against the side of the actuating arm 47 facing the roller seat 2. Since the waste discharge door 41 has a tendency to switch to the closed state, the transmission end of the waste discharge actuating member 45 has a tendency to move towards the actuating arm 47, so that the other end of the actuating arm 47 has a tendency to move away from the direction where the roller seat 2 is located. The waste discharge drive stop 46 is fixedly mounted on the base 1. The waste discharge drive stop 46 is a plate parallel to the mounting end face of the roller seat 2. The actuating swing arm 47 is driven by the roller seat 2 and can be squeezed by the waste discharge drive stop 46 and swing towards the roller seat 2, so that the waste discharge actuating component 45 is squeezed by the actuating swing arm 47 and rotates, so that the waste discharge door 41 is driven by the waste discharge actuating component 45 to switch to the open state. When the actuating swing arm 47 disengages from the waste discharge drive stop 46, the waste discharge door 41 is reset to the closed state under the action of the waste discharge reset component. By using the design of the actuating swing arm 47 being squeezed by the waste discharge drive stop 46 to drive the waste discharge door 41 to switch to the open state, the waste discharge door 41 will remain open after the roller seat 2 rotates to a preset angle, which is more conducive to the discharge of sand in the toilet compartment 21 from the waste discharge port.

[0073] like Figure 20 , Figure 21 and Figure 22As shown, the waste discharge actuating component 45 includes an actuating rod 451 and a rotating seat 452. The rotating seat 452 is rotatably mounted on the roller seat 2, and the transmission end is formed on the rotating seat 452. One end of the actuating rod 451 is the actuating end, and the other end of the actuating rod 451 is connected and fixed to the rotating seat 452. The connection position of the actuating rod 451 and the rotating seat 452, and the setting position of the transmission end of the rotating seat 452, are respectively located on opposite sides of the rotation axis of the rotating seat 452. This ensures that when the transmission end of the rotating seat 452 is pressed by the actuating arm 47, the actuating end of the actuating rod 451 moves towards the interior of the toilet compartment 21. This design makes the waste discharge door 41 an inward-opening door, avoiding the safety hazard of the waste discharge door 41 colliding with the collection mechanism 30 during opening.

[0074] like Figure 22 As shown, a swing arm limiting member 49 is provided on the mounting end face of the roller seat 2. A return spring 48 is compressed between the actuating swing arm 47 and the roller seat 2, so that the actuating swing arm 47 has a tendency to swing in the opposite direction to the roller seat 2. The swing arm limiting member 49 is used to limit the range of motion of the actuating swing arm 47 in the opposite direction to the roller seat 2. By providing a return spring 48, the actuating swing arm 47 can have its own reset capability, thereby reducing the load on the waste discharge reset member and making the transmission structure of the waste discharge control mechanism 4 more reasonable.

[0075] like Figure 23 , Figure 24 , Figure 25 and Figure 27 As shown, a locking protrusion 26 is formed on the mounting end face of the roller seat 2. The locking protrusion 26 is a cylindrical boss. The central axis of the locking protrusion 26 is collinear with the rotation axis of the roller seat 2. A locking flange 261 is formed on the circumferential surface of the locking protrusion 26. The system also includes a locking assembly 50, which includes a locking seat 501 and a clamping member 502. The locking seat 501 is fixedly mounted on the waste discharge drive stop 46. A clamping part 5011 is formed on the locking seat 501. The clamping part 5011 has an arc-shaped structure. The clamping member 502 is slidably mounted on the locking seat 501. The clamping member 502 has an arc-shaped structure. The clamping member 502 slides toward the clamping part 5011 and can cooperate with the clamping part 5011 to clamp and position the circumferential surface of the locking protrusion 26. The locking flange 261 is used to prevent the clamping part 5011 and the clamping member 502 from disengaging from the locking protrusion 26 when they are in a clamping state. The above structure makes the connection between the base 1 and the roller seat 2 more stable and facilitates installation and disassembly. The disk 72 of the magnetic encoder 7 is disposed on the end face of the locking protrusion 26, and the magnetic sensor 71 of the magnetic encoder 7 is disposed on the locking seat 501.

[0076] like Figure 23 , Figure 24 and Figure 25 As shown, the locking assembly 50 further includes a swing handle 503 and two transmission connectors 504. The swing handle 503 is rotatably mounted on the locking seat 501. The two transmission connectors 504 are located on both sides of the swing handle 503. One end of each transmission connector 504 is rotatably connected to the swing handle 503, and the other end is rotatably connected to the clamping member 502 and slidably mounted on the locking seat 501. This allows the swing handle 503 to rotate and drive the clamping member 502 to slide closer to or further away from the clamping part 5011. By adding the swing handle 503 and the transmission connectors 504, the user can operate the locking assembly 50 more conveniently.

[0077] like Figure 23 , Figure 24 and Figure 25As shown, the swing handle 503 has a U-shaped structure. Locking holes are formed on the inner walls of opposite sides of the U-shaped structure of the swing handle 503. Both ends of the U-shaped structure of the swing handle 503 are rotatably connected to the locking seat 501. A locking slide 5012 is formed on the locking seat 501, and two clamping protrusions 5013, two locking channels 5014, and a positioning protrusion 5015 are formed on the locking slide. When the clamping part 5011 and the clamping member 502 are in a clamping state, the locking slide... 5012 is located inside the U-shaped structure of the swing handle 503, and the openings of the two locking channels 5014 are aligned with the two locking holes one-to-one. A locking slider 505 is slidably disposed in the locking slide 5012, and the locking slider 505 has two clamping recesses 5051 and a positioning groove 5052. The two locking channels 5014 are located on opposite sides of the locking slide 5012, and a locking pin 506 is slidably disposed in each locking channel 5014. A locking elastic element 507 is compressibly disposed between the locking pin 506 and the corresponding locking channel 5014, at the opening furthest from the locking slide 5012, so that the locking pin 506 protrudes from the locking slide 5012 when no external force is applied; the locking slider 505 slides so that its two clamping recesses 5051 and two clamping protrusions 5013 are nested one-to-one with each other, and the positioning groove 5052 and the positioning protrusion 5015 are nested and positioned with each other, thus locking the two locking pins 506. The slider 505 is pressed and slides away from the locking slide 5012, causing one end of each of the two locking pins 506 to extend from the corresponding locking channel 5014 away from the locking slide 5012 and insert into the two locking holes of the swing handle 503 for locking. When the locking pins 506 are in the locked state, the two locking pins 506 and the two clamping protrusions 5013 cooperate to clamp and position the locking slider 505, preventing the locking slider 505 from slipping off due to its own weight and unlocking. By adding a locking structure to the swing handle 503, the clamping state of the clamping part 5011 and the clamping member 502 can be prevented from being released due to the swing handle 503 swinging due to its own weight and other factors, thereby improving the reliability and stability of the locking assembly 50.

[0078] like Figure 20 and Figure 21As shown, the roller seat 2 includes a shell 27, a cover plate 28, and a sand storage tray 29. The shell 27 is a cylindrical structure with one open end. The inner cavity of the shell 27 forms the filter sand chamber 22, the sand storage chamber 23, the sand replenishment channel 24, and the waste discharge port. The sand storage tray 29 is detachably connected to the shell 27 and slides into the inner cavity of the shell 27 from the opening, such that the sand storage tray 29, the filter sand chamber 22, the sand replenishment channel 24, and the sand storage chamber 23 are arranged sequentially around the axis of the shell 27. The cover plate 28 is detachably installed on the opening of the shell 27 to cover it, so that the cover plate 28, the sand storage tray 29, and the inner wall of the shell 27 together form the toilet chamber 21. This design allows the sand particles in the toilet chamber 21 to be stored on the sand storage tray 29 in standby mode. The detachable structure of the sand storage tray 29 facilitates manual replacement of the sand particles in the toilet chamber 21 by the user.

[0079] like Figure 20 , Figure 22 , Figure 26 and Figure 27As shown, in this embodiment, the driven gear 52 is an annular tooth structure disposed on the mounting end face of the roller seat 2. The central axis of the driven gear 52 is collinear with the rotation axis of the roller seat 2, and the driven gear 52 and the driving gear 51 are meshed in an internally tangential manner. In addition, in this embodiment, the first limiting protrusion 12 and the sand replenishing drive rack 33 of the sand replenishing control mechanism 3 are both disposed on the waste discharge drive stop 46. The waste discharge drive stop 46 has a pressing guide 461 for guiding the movement of the swing arm 47. The pressing guide 461, the sand replenishing drive rack 33, and the first limiting protrusion 12 are arranged sequentially from the inside to the outside relative to the rotation axis of the roller seat 2. The sand replenishment control mechanism 3 also includes a transmission gear 36; the transmission gear 36, the first transmission shaft 34, and the second transmission shaft 35 are all rotatably mounted on the drum seat 2. The second transmission shaft 35 and the first transmission shaft 34 are coaxially arranged. The rotation axes of the sand replenishment drive shaft 32, the transmission gear 36, and the first transmission shaft 34 are arranged parallel to each other and are arranged in sequence along the radial direction of the cross-section of the drum seat 2. The sand replenishment drive shaft 32 is meshed with the transmission gear 36, and the first transmission shaft 34 is meshed with the transmission gear 36. As described in Embodiment 1, the second transmission shaft 35 can only drive the first transmission shaft 34 to rotate when rotating in the opposite direction. The second transmission shaft 35 can be driven by the drum seat 2 to engage with the sand replenishment drive rack 33. Compared with Embodiment 1, the sand replenishment control mechanism 3, by adding a transmission gear 36, allows the transmission position between the sand replenishment drive shaft 32 and the sand replenishment drive rack 33 to be closer to the axis of the roller seat 2. This achieves that the transmission positions between the sand replenishment drive shaft 32 and the sand replenishment drive rack 33, the transmission positions between the actuating swing arm 47 and the waste discharge drive stop 46, the transmission positions between the driven gear 52 and the driving gear 51, and the contact positions between the first limiting protrusion 12 and the second limiting protrusion 25 are staggered, making the transmission structure distribution of this intelligent pet toilet more reasonable.

[0080] In this embodiment, the sand-filling door 10 is also equipped with a magnetic component, and the roller seat 2 is equipped with a Hall sensor (the magnetic component and Hall sensor are not shown in the attached drawings). The locking seat 501 is equipped with a processing module 60 electrically connected to the Hall sensor. The processing module 60 is electrically connected to the control module 40. The processing module 60 determines whether the sand-filling door 10 has been manually opened based on whether the Hall sensor is triggered by the magnetic component and feeds the information back to the control module 40. The control module 40 adjusts the start timing of the sand block cleaning program based on the information from the processing module 60, so as to avoid starting the sand block cleaning program when the sand-filling door 10 is manually opened, which would affect normal operation or cause serious consequences, thus eliminating safety hazards.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
