[0050] Reference Figure 1-9 As shown, an automatic cat litter box comprising:

[0051] A basin body 100, wherein a cavity for containing cat litter is provided at the top of the basin body 100, and a cat feces basin 700 is detachably provided at the edge of the basin body 100;

[0052] The handpiece 200 is detachably mounted above the cavity, and the handpiece 200 can slide relative to the basin body 100;

[0053] A displacement driving device 300, wherein the displacement driving device 300 is used to drive the head 200 to perform reciprocating motion along the extension direction of the cavity;

[0054] The drum 400 is rotatably mounted in the machine head 200 and can be driven to rotate. Two or more rakes 410 are provided on the surface of the drum 400. When the drum 400 rotates, the rakes 410 are used to scoop up the block in the transfer cavity.

[0055] Among them, a transfer chamber 500 is provided behind the drum 400 in the head 200, and the transfer chamber 500 is used to temporarily store the blocks scooped up by the rake 410. When the head 200 is in the initial position, the transfer chamber 500 is connected to the cat feces bowl 700.

[0056] The invention aims to solve the problems of serious waste of cat litter, incomplete cleaning and difficulty in cleaning in the existing cat litter box during the cleaning process. The design combines the head 200 with the drum 400 and utilizes the displacement drive device 300, so that the entire cleaning process is more efficient and thorough, and is easy to maintain and clean. A cavity is provided at the top for accommodating cat litter. A cat feces basin 700 is detachably provided on the edge of the basin body 100 to facilitate pouring out the collected excrement. The head 200 is driven to reciprocate along the extension direction of the cavity to ensure that the head 200 can cover the entire cavity. It is installed in the head 200 and can be driven to rotate. Two or more spike rakes 410 are provided on the surface of the drum 400. When the drum 400 rotates, the spike rakes 410 can scoop up and transfer lumps such as cat feces in the cavity.

[0057] After the cat defecates in the cat litter box, the displacement drive device 300 starts and drives the machine head 200 to reciprocate along the extension direction of the cavity. The drum 400 in the machine head 200 starts to rotate, and the spike rake 410 on the surface of the drum 400 scoops up and transfers the lumps in the cavity. After the spike rake 410 scoops up the lumps, the lumps are transferred to the transfer cavity 500 behind the drum 400 for temporary storage. When the machine head 200 returns to the initial position, the transfer cavity 500 is connected to the cat litter box 700, and the temporarily stored lumps of cat feces are transferred to the cat litter box 700. The design of the transfer cavity 500 is intended to provide a temporary storage space so that the lumps can be temporarily stored during the mobile cleaning process of the machine head 200, and then processed in a centralized manner. The design of the transfer cavity 500 solves the problem of temporary storage of lumps when the machine head 200 is moving for cleaning, ensuring the continuity of the cleaning process. Through the cooperation of the transfer chamber 500 and the cat litter tray 700, the excrement is centrally processed, and the dispersion and retention of lumps in the cat litter tray are avoided. The head 200 can continue to work during the cleaning process without interruption due to the processing of lumps, thereby improving the cleaning efficiency. The lumps are centrally transferred to the cat litter tray 700 through the transfer chamber 500, reducing the waste of cat litter and the problem of incomplete cleaning.

[0058] By combining the displacement drive device 300 and the drum 400, the head 200 can cover the entire cavity, ensuring that cat feces in every position can be cleaned. The spike rake 410 on the drum 400 can pick up cat feces of various shapes, improve the compatibility of cat litter, and reduce the waste of cat litter. The design of the head 200, the drum 400 and the spike rake 410 allows these components to be easily disassembled for easy cleaning and maintenance. The design of the basin body 100 and the cat feces basin 700 also takes into account convenient disassembly, making it easy to pour out the collected excrement and clean it.

[0059] By improving the movement of the machine head 200 and the operation of the spike rake 410, a more thorough cleaning of the cat litter and the leveling of the cat litter box can be achieved. By allowing the spike rake 410 to perform a reverse and leveling operation when the machine head 200 returns to the initial position, a double cleaning of the cat litter box is achieved to ensure that no cat feces are missed and the cat litter is kept clean and uniform. The machine head 200 starts and moves along the cavity, the drum 400 rotates, and the spike rake 410 picks up the lumps in the cat litter box and transfers them to the transfer cavity 500. During the return of the machine head 200, the spike rake 410 can be set to reverse to smooth and level the cat litter and restore the cat litter to its original state. Alternatively, the spike rake 410 can be set to rotate forward to clean up the cat feces that may be missed to ensure that there are no dead corners in the cleaning.

[0060] In this embodiment, the inner wall of the basin body 100 is provided with a slide groove 130, and rollers 230 are provided on both sides of the head 200. The rollers 230 are located in the slide groove 130, and the head 200 is slidably installed above the basin body 100 through the cooperation between the rollers 230 and the slide groove 130.

[0061] The top of the chute 130 is provided with a through slot for the roller 230 to pass through, and the head 200 can be detachably installed through the through slot. By adding the chute 130 and the roller 230 structure, the stability and accuracy of the movement of the head 200 in the cat litter box are improved, and the removal and installation of the head 200 are convenient. This design can improve the working efficiency of the automatic cat litter box and simplify daily maintenance and cleaning work.

[0062] Through the through slot at the top of the slide 130, the roller 230 of the machine head 200 is aligned with the through slot, and the machine head 200 can be loaded into the slide 130 from above. After the roller 230 enters the slide 130, the machine head 200 can slide in the slide 130. During operation, the displacement drive device 300 drives the machine head 200 to reciprocate along the slide 130. The roller 230 slides in the slide 130, making the movement of the machine head 200 more stable and precise. When cleaning or maintenance is required, move the machine head 200 to the through slot position at the top of the slide 130, and the machine head 200 can be easily disassembled through the through slot.

[0063] The through-slot design makes the disassembly of the handpiece 200 simple and quick, and is convenient for users to clean and maintain. The detachable design of the handpiece 200 and the roller 230 makes it easy for users to clean the roller 230, the slide 130 and the inside of the handpiece 200, prevent dirt from being trapped, and keep the equipment clean and hygienic. The design of the roller 230 and the slide 130 reduces the direct friction between the handpiece 200 and the basin 100, reduces the wear of the equipment, and extends the service life of the equipment.

[0064] In this embodiment, a notch 510 for allowing the block to pass through is provided below the transfer chamber 500, and a flip plate 520 is rotatably installed at the notch 510;

[0065] The flip plate 520 has a first position state covering the notch 510 and a second position state located at the side of the notch 510 .

[0066] The transfer chamber 500 is located in the machine head 200 and is used to temporarily store the block objects such as cat feces picked up by the drum 400 and the rake 410. The notch 510 is set below the transfer chamber 500 for the block objects to pass through. The flip plate 520 is installed at the notch 510 and can be rotated to cover or open the notch 510. It has two positions. The first position covers the notch 510 to prevent the block objects from passing through. The second position is located on the side of the notch 510 to allow the block objects to pass through.

[0067] The machine head 200 starts and moves in the cavity, the drum 400 rotates, and the rake 410 picks up the lumps in the cat litter box and transfers them to the transfer cavity 500. During this process, the flip plate 520 remains in the first position, covering the gap 510, ensuring that the lumps are temporarily stored in the transfer cavity 500 and will not fall. When the machine head 200 completes the cleaning and returns to the top of the cat litter box 700, the flip plate 520 rotates to the second position and the gap 510 opens. The lumps in the transfer cavity 500 fall into the cat litter box 700 below through the gap 510, realizing the transfer of the lumps.

[0068] The design of the flip plate 520 ensures that the lumps in the transfer chamber 500 can be transferred to the cat feces tray 700 in a timely and smooth manner, thereby avoiding the lumps from being retained for a long time and improving the cleaning efficiency.

[0069] In another implementation case, through an intelligent control system, the flip plate 520 can accurately switch between two position states, thereby automating the cleaning process and providing a better user experience.

[0070] In this embodiment, a flip track 120 is provided on the side of the basin body 100;

[0071] A flip chute 130530 is provided on the side of the transfer chamber 500, and a driving part 521 is provided on the side of the flip plate 520 and passes through the flip chute 130530 and is located in the flip track 120;

[0072] The flip track 120 is provided with a bending portion 121. When the flip plate 520 follows the head 200 to move along the extension direction of the cavity, the bending portion 121 of the flip track 120 cooperates with the driving portion 521 to drive the flip plate 520 to switch between the first position state and the second position state. Through the ingenious cooperation between the flip track 120 and the flip plate 520, efficient transfer and centralized processing of lumps in the automatic cat litter box can be achieved. Through the interaction between the bending portion 121 of the flip track 120 and the driving portion 521 of the flip plate 520, the state switching of the flip plate 520 is automatically controlled during the movement of the head 200, ensuring the continuity and efficiency of the cleaning process.

[0073] When the machine head 200 starts to move for cleaning, the flip plate 520 moves along the extension direction of the cavity with the machine head 200. The driving unit 521 moves in the flip track 120. When passing through the bending portion 121 of the flip track 120, the driving unit 521 pushes the flip plate 520 to switch from the second position state to the first position state, covering the gap 510 to prevent the block from falling. The flip plate 520 is maintained in the first position state, the machine head 200 continues to clean, and the block is picked up and temporarily stored in the transfer cavity 500. When the machine head 200 completes the cleaning and returns to the initial position, the driving unit 521 passes through the bending portion 121 of the flip track 120 again. Under the guidance of the bending portion 121, the flip plate 520 switches from the first position state to the second position state, opening the gap 510. The block in the transfer cavity 500 falls into the cat feces pot 700 below through the gap 510, realizing the transfer and centralized treatment of the block.

[0074] The state switching of the flip plate 520 is automatically controlled by the movement of the head 200 and the bending portion 121 of the flip track 120, which realizes the fully automated operation of the cleaning process, reduces the manual intervention of the user, and improves the convenience of use. Through the ingenious mechanical design of the flip track 120 and the flip plate 520, efficient transfer and centralized processing of block objects are achieved. The design utilizes the natural drive of mechanical movement and does not require an additional motor to control the flip plate 520, thereby reducing the cost of the equipment while ensuring the continuity and efficiency of the cleaning process. After removing the motor, the overall structure is more compact and saves space.

[0075] A through slot is also provided at the top of the flip track 120. When the machine head 200 is separated from the basin body 100, the driving unit 521 passes through the through slot to separate the flip track 120. When the machine head 200 needs to be disassembled for maintenance or cleaning, the machine head 200 is moved to the through slot position at the top of the flip track 120. The driving unit 521 passes through the through slot and is separated from the flip track 120, which facilitates the separation of the machine head 200 from the basin body 100. After the machine head 200 is separated, the roller 400, the rake 410 and the flip plate 520 can be easily disassembled for thorough cleaning and maintenance. After the maintenance is completed, the machine head 200 is reinstalled on the basin body 100, and the driving unit 521 re-enters the track through the through slot at the top of the flip track 120 to resume normal operation.

[0076] In this embodiment, the head 200 includes a shell body 220 and a side cover 210, and the side cover 210 is detachably connected to the shell body 220;

[0077] The drum 400 and the flip plate 520 are installed between the side cover 210 and the shell body 220 . When the side cover 210 is removed, the drum and the flip plate 520 can be taken out from the shell body 220 .

[0078] Through the modular and easily disassembled structure, the key components such as the head 200, the rake 410, and the flip plate 520 can be easily disassembled and separated from the cat litter box body, thereby achieving dry and wet separation, which is convenient for thorough cleaning and maintenance. This design not only improves the hygiene level of the equipment, but also extends the service life of the equipment. · Remove the head 200 from the cat litter box body, and separate the side cover 210 connected by the buckle from the shell body 220. After removing the side cover 210, the drum 400 and the flip plate 520 can be easily taken out from the shell body 220. Through the above disassembly process, the head 200 is completely separated from the drum 400, the flip plate 520, and the drum 400, avoiding moisture and dirt accumulation inside the equipment. The cat litter box body, cat feces tray 700, the drum 400 and the flip plate 520 can all be completely rinsed with water to ensure that each component is thoroughly cleaned to avoid bacterial growth and odor.

[0079] By separating the heavily polluted parts from the electrical part, the dry and wet parts of the equipment are separated, which makes it easier to clean and maintain. This design not only improves the hygiene level of the equipment, but also avoids failures of the electrical part due to moisture or pollution, thus extending the service life of the equipment.

[0080] In this embodiment, a transfer grid plate 540 is provided between the transfer chamber 500 and the drum 400. The position of the through slot on the transfer grid plate 540 corresponds to the nail rake 410. The nail rake 410 can pass through the transfer grid plate 540.

[0081] The transfer grid plate 540 is inclined toward the transfer chamber 500 to guide the lumps into the transfer chamber 500. Driven by the drum 400, the rake 410 rotates slowly. When the rake 410 rotates in the lower half of the drum 400, the rake 410 is inserted into the cat litter to take out the lumps. When the rake 410 continues to move upward and exceeds the vertex to the rear of the drum 400, the lumps fall on the transfer grid plate 540 with the rake 410 under the action of gravity, and enter the transfer chamber 500 under the guidance of the transfer grid plate 540. The rake 410 slowly rotates through the transfer grid plate 540 and continues to rotate for cleaning. The inclined transfer grid plate 540, with one end close to the transfer chamber 500 and the other end close to the upper half of the drum 400, is to reduce the collision of the lumps due to the large height difference during the transportation process, which easily causes the lumps to scatter and fall back on the cat litter.

[0082] The design of the transfer grid 540 enables the blocks to be smoothly transferred from the drum 400 to the transfer chamber 500, reducing the problem of block scattering caused by the height difference during the transfer process. The through groove corresponds to the spike rake 410, and the spike rake 410 can pass through the transfer grid 540 to continue the cleaning operation, ensuring the continuity and smoothness of the cleaning process. The inclined transfer grid 540 reduces the impact and scattering of blocks during the transfer process, prevents the blocks from falling back into the cat litter, and improves the cleaning efficiency. The transfer grid 540 has a simple and reliable structure, and the inclined design conforms to the natural movement path of blocks under the action of gravity, which improves the stability and reliability of the equipment.

[0083] In this implementation case, the displacement driving device 300 includes:

[0084] A displacement motor 310, wherein the displacement motor 310 is installed in the machine head 200;

[0085] A rack 330, wherein the rack 330 is installed in the top groove 140 of the basin body 100;

[0086] The displacement motor 310 is meshed with the rack 330 through the gear set 320 to drive the machine head 200 to move.

[0087] The displacement drive device 300 is designed to achieve smooth movement and efficient cleaning of the head 200 in the cat litter box. Through the cooperation of the displacement motor 310, the rack 330 and the gear set 320, the head 200 can reciprocate along the cavity direction of the cat litter box. The rack 330 is installed on the side of the groove 140 at the top of the basin body 100, so that the gear and the rack 330 can be easily separated when the head 200 is disassembled, simplifying maintenance and cleaning work.

[0088] The displacement motor 310 is installed in the head 200 and is responsible for driving the movement of the head 200. The rack 330 is installed on the side of the groove 140 at the top of the cat litter box to facilitate the engagement and separation of the gear and the rack 330. The gear set 320 connects the displacement motor 310 and the rack 330 to transmit power so that the head 200 moves along the direction of the rack 330.

[0089] The displacement motor 310 is started, and the gear set 320 meshes with the rack 330, driving the head 200 to move along the direction of the cat litter box. The rack 330 is designed on the side of the top groove 140 to ensure that the head 200 can move smoothly along the cat litter box to perform cleaning operations. During the movement of the head 200, the drum 400 and the rake 410 rotate and scoop up the lumps in the cat litter and transfer them to the transfer chamber 500. When the head 200 needs to be disassembled for maintenance or cleaning, it is only necessary to remove the head 200 from the cat litter box, and the gear and rack 330 will naturally separate, simplifying the disassembly process. The side installation of the rack 330 makes disassembly and reinstallation very convenient, improving maintenance efficiency.

[0090] The cooperation of the rack 330 and the gear set 320 ensures the smooth movement of the head 200 in the cat litter box, reduces vibration and jamming, and improves cleaning efficiency. The rack 330 is installed on the side of the top groove 140, so that when the head 200 is disassembled, the gear and the rack 330 can be easily separated, simplifying the disassembly and maintenance process.

[0091] In this embodiment, the inner wall of the cavity is provided with a drain port 150, and the drain port 150 is connected to the top groove 140 of the basin body 100. The inner wall of the cavity is provided with a drain port 150, and the drain port 150 is connected to the top groove 140 of the basin body 100, which solves the problem that the cat litter box is used in a bad environment and debris may fall into the top groove 140 to affect the normal operation of the device. Through this design, when debris falls into the top groove 140, it can fall into the cavity through the drain port 150, thereby ensuring the normal operation and cleaning efficiency of the device.

[0092] The inner wall of the cavity is provided with a sewage outlet 150. The sewage outlet 150 is connected with the top groove 140 of the basin body 100 to form a sewage channel. The top groove 140 is located at the top of the basin body 100 and is used for the installation of the rack 330 and the movement of the equipment.

[0093] Since the environment in which the cat litter box is used is relatively harsh, cat litter or other debris may fall into the top groove 140 of the basin body 100. Through the design of the drain outlet 150, these debris can be discharged from the top groove 140 through the drain outlet 150 and fall into the cavity, thereby preventing debris from accumulating in the top groove 140 and affecting the normal operation of the equipment. The drain outlet 150 is connected to the top groove 140 to ensure that the debris that falls into the groove can be discharged smoothly, avoiding blockage problems caused by accumulation of debris, and ensuring the normal operation of the equipment. By removing debris in a timely manner, the impact on the rack 330 and the gear set 320 is reduced, and the reliability and durability of the equipment are improved. The automated sewage discharge design reduces the user's maintenance workload and frequency, and improves the user experience and the convenience of using the equipment.

[0094] In this embodiment, a rotary motor 600 is provided in the machine head 200, and the rotary motor 600 is installed on the side wall of the machine head 200;

[0095] The drum 400 is sleeved on the outside of the rotary motor 600 , and the rotary motor 600 drives the drum 400 to rotate via a transmission member 610 .

[0096] By setting a rotary motor 600 in the head 200, the drum 400 is rotated, and the movement of the dual motors is used to enable the head 200 to move forward and backward and the rake 410 to rotate independently. This not only improves the stability of the equipment, but also makes the cleaning process more flexible and efficient. The forward and backward movement can be stopped at any time, and the cat feces can be cleaned continuously by self-rotation, ensuring thorough cleaning.

[0097] Displacement motor 310: drives the machine head 200 to move forward and backward along the direction of the cavity of the cat litter box. The displacement motor 310 meshes with the rack 330 through the gear set 320 to achieve smooth movement of the machine head 200. Rotation motor 600: installed on the side wall of the machine head 200, drives the drum 400 to rotate through the transmission member 610. The spike rake 410 on the surface of the drum 400 picks up the lumps in the cat litter during the rotation process and transfers them to the temporary cat feces box 700.

[0098] The two motion modes of forward and backward movement and the rotation of the spike rake 410 can be performed independently at any time. Even during the forward and backward movement, the head 200 can be stopped at any time, and the spike rake 410 continues to rotate, shoveling the cat feces wherever it goes into the temporary cat feces basin 700 to ensure thorough cleaning. When the forward and backward movement is paused, the spike rake 410 can still continue to rotate to ensure that the cleaning work is not interrupted. The dual-motor motion mode enables the forward and backward movement of the head 200 and the rotation of the spike rake 410 to be performed independently, avoiding the excessive burden on a single motor and improving the stability of the equipment. The independent operation of the forward and backward movement and the rotation of the spike rake 410 makes the cleaning process more flexible. The forward and backward movement can be paused at any time, while the spike rake 410 continues to rotate to ensure that the cat feces in each position can be cleaned up.

[0099] In another embodiment, the roller 400 and the rack 330 in the top groove 140 can be connected by a bevel gear set 320. When the displacement motor 310 starts to drive the head 200 to move, the bevel gear set 320 meshes with the rack 330. When the bevel gear set 320 follows the displacement of the head 200, the bevel gear set 320 also rotates, thereby driving the roller 400 to rotate. The use of the bevel gear set 320 to connect the roller 400 and the rack 330 and the displacement motor 310 to drive the roller 400 to rotate simplifies the device structure and reduces the need for additional motors.

[0100] In this embodiment, the bottom surface of the basin body 100 is provided with feet 800 to form a ventilation gap between the bottom surface and the supporting surface;

[0101] The bottom side of the basin body 100 is also provided with a ventilation hole connected to the inside of the basin body 100. By providing the foot pads 800 and the ventilation holes on the bottom surface of the cat litter box, the problem of easy water accumulation and keeping dryness in the cat litter box during cleaning is solved. By forming the design of the ventilation gap and the ventilation holes, the basin body 100 can discharge the infiltrated water during the cleaning process, keep dry, reduce bacterial growth, and improve the hygiene level of the equipment.

[0102] When the basin body 100 needs to be cleaned, water may penetrate into some gaps that are not waterproofed. Through the ventilation hole design, the infiltrated water can be discharged through the ventilation holes to prevent water from accumulating in the basin body 100. The foot pad 800 is designed to form a ventilation gap between the bottom surface of the basin body 100 and the supporting surface, so that air can circulate and keep the basin body 100 dry. The ventilation holes further promote air flow, accelerate water evaporation, keep the interior dry, and reduce the chance of bacterial growth. After cleaning, the interior of the basin body 100 is quickly dried through the ventilation holes and ventilation gaps, which is convenient for reuse and maintenance, ensuring the long-term hygiene and reliability of the equipment. The design takes into account drainage and ventilation during the cleaning process, keeps the interior of the basin body 100 dry and clean, and improves the overall hygiene level of the cat litter box.

[0104] The rotation radius of the head of the spike rake 410 is equal to the distance between the center of the drum 400 and the bottom of the cavity. By arranging the arc surface 170 at both ends of the cavity to match the rotation trajectory of the spike rake 410, the spike rake 410 can be closely attached to the arc surface 170 during rotation, achieving a more efficient cleaning effect. At the same time, the rotation radius of the head of the spike rake 410 is equal to the distance between the center of the drum 400 and the bottom of the cavity, ensuring thoroughness and accuracy during the cleaning process.

[0105] The drum 400 rotates under the drive of the rotary motor 600 or the bevel gear set 320, and the spike rake 410 rotates with the drum 400. During the rotation process, the spike rake 410 is close to the arc surface 170 to ensure that the distance from the bottom of the cavity is equal to avoid missing any lumps. When the spike rake 410 passes through the arc surface 170 area, it can pick up the lumps in the cat litter and transfer them to the transfer cavity 500 to achieve efficient cleaning.

[0106] The rotation radius of the head of the spike rake 410 is equal to the distance between the center of the drum 400 and the bottom of the cavity, ensuring that the spike rake 410 can cover every position of the bottom of the cavity during the rotation process to achieve thorough cleaning.

[0107] The coordination of the gear set ensures the smooth movement of the machine head in the cat litter box, reduces vibration and jamming, and improves cleaning efficiency. The rack is installed on the side of the top groove, so that the gear and rack can be easily separated when the machine head is disassembled, simplifying the disassembly and maintenance process.

[0108] In this embodiment, the inner wall of the cavity is provided with a drain outlet, which is connected to the top groove of the basin body. The inner wall of the cavity is provided with a drain outlet, and the drain outlet is connected to the top groove of the basin body, which solves the problem that the cat litter box is used in a harsh environment and debris may fall into the top groove and affect the normal operation of the device.

[0109] The inner wall of the cavity is provided with a sewage outlet, which is connected with the top groove of the basin body to form a sewage discharge channel. The top groove is located at the top of the basin body and is used for the installation of the rack and the movement of the equipment.

[0110] Since the litter box is used in a harsh environment, cat litter or other debris may fall into the top groove of the basin. Through the design of the drain port, these debris can be discharged from the top groove through the drain port and fall into the cavity, avoiding the accumulation of debris in the top groove and affecting the normal operation of the equipment. The drain port is connected to the top groove to ensure that the debris that falls into the groove can be discharged smoothly, avoiding blockage caused by the accumulation of debris and ensuring the normal operation of the equipment. By removing debris in time, the impact on the rack and gear set is reduced, and the reliability and durability of the equipment are improved.

[0112] The roller is sleeved on the outside of the rotating motor, and the rotating motor drives the roller to rotate through a transmission member.

[0113] By setting a rotating motor in the machine head to realize the rotation of the drum, and using the movement of the dual motors, the forward and backward movement of the machine head and the rotation of the spike rake can be performed independently. This not only improves the stability of the equipment, but also makes the cleaning process more flexible and efficient. It can stop moving forward and backward at any time and continue to rotate to clean cat feces, ensuring thorough cleaning.

The displacement motor meshes with the rack through the gear set to achieve smooth movement of the machine head. Rotation motor: installed on the side wall of the machine head, drives the drum to rotate through the transmission parts. The spike rake on the surface of the drum picks up the lumps in the cat litter during the rotation process and transfers them to the temporary cat feces box.

[0115] The two movement modes of forward and backward movement and rake rotation can be performed independently at any time. Even during the forward and backward movement, the machine head can be stopped at any time, and the rake continues to rotate, shoveling the cat feces wherever it reaches into the temporary cat feces basin to ensure thorough cleaning. When the forward and backward movement is paused, the rake can still continue to rotate to ensure that the cleaning work is not interrupted. The dual-motor movement mode enables the forward and backward movement of the machine head and the rotation of the rake to be performed independently, avoiding the excessive burden on a single motor and improving the stability of the equipment. The independent operation of the forward and backward movement and the rotation of the rake makes the cleaning process more flexible. The forward and backward movement can be paused at any time, while the rake continues to rotate to ensure that the cat feces in each position can be cleaned up.

[0116] In another implementation case, the roller and the rack in the top groove can be connected by a bevel gear set. When the displacement motor starts to drive the machine head to move, the bevel gear set meshes with the rack. When the bevel gear set follows the displacement of the machine head, the bevel gear set also rotates, thereby driving the roller to rotate. Using a bevel gear set to connect the roller and the rack, and driving the roller to rotate by the displacement motor, simplifies the equipment structure and reduces the need for additional motors.
