Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a feces collection device. Background Technology

[0002] A litter box is an essential item for pets' daily life. Existing litter boxes consist of a litter box body and two collection chambers located at both ends of the litter box body. Each collection chamber is equipped with a door that can be closed or opened. The litter box body has a grid that can move back and forth inside the litter box body to push the feces into the collection chamber.

[0003] Currently, the waste collection function is achieved through the linkage between the grille and the bin door. When the grille approaches any waste bin, the corresponding bin door automatically opens; when the grille moves away, the bin door closes. In other words, the grille and waste bin are in the same position when the bin door is about to open and close. On one hand, for normal pet use, both waste bins need to be closed. Without the grille's linkage with either bin door, the grille would need to be located in the middle of the litter box, encroaching on the pet's usable space and significantly affecting its use. On the other hand, to avoid the grille encroaching on the pet's space, the linkage distance between the grille and the bin door is minimized. This means that when the bin door opens, the door pushes feces or urine off the grille, resulting in incomplete cleaning.

[0004] Therefore, there is an urgent need for fecal collection devices to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a feces collection device that can ensure that excrement on the grid is not pushed off the excrement container by the door when the collection chamber is open, thereby improving the efficiency of scooping and the cleanliness of the home space, and increasing the pet's usable space when the collection chamber is closed.

[0031] Beneficial effects:

[0032] This invention provides a feces collection device. During the feces collection process, the grille and the sliding component move synchronously. When the sliding component abuts against the opening critical point A, the chamber door is about to open. At this time, the distance between the lower edge of the grille and the lower edge of the opening of the collection chamber is L1. The linkage rotates under the action of the sliding component. The sliding component can reciprocate between the opening critical point A and the closing critical point B. During the movement of the sliding component from the opening critical point A to the closing critical point B, the chamber door gradually opens until it is fully open. The grille pushes the feces into the collection chamber. When the sliding component abuts against the closing critical point B, the linkage moves to make the chamber door just close. At this time, the distance between the lower edge of the grille and the lower edge of the opening of the collection chamber is L2, completing one feces collection operation, where L1>L2. This feces collection device can ensure that the excrement on the grille is not pushed off the chamber door and outside the excrement container during the opening of the collection chamber, improving the cleaning effect and the cleanliness of the home space, and increasing the pet's usable space when the collection chamber is closed.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0069] This embodiment provides a fecal collection device, such as... Figures 1-7 As shown, the fecal collection device includes a discharge vessel 1, a chamber door 3, a linkage 4, and a sliding assembly 51. The discharge vessel 1 can hold absorbent material. At least one end of the discharge vessel 1 is provided with a fecal collection chamber 11, which has an opening communicating with the discharge vessel 1. A grid 21 is slidably provided inside the discharge vessel 1. The chamber door 3 is rotatably connected to the discharge vessel 1 and is used to open or close the opening. One end of the linkage 4 is rotatably connected to the side wall of the discharge vessel 1, and the other end of the linkage 4 is connected to or abuts against the lower surface of the chamber door 3. An opening critical point A and a closing critical point B are provided at intervals along the first direction on the linkage 4. The opening critical point A is the critical point at which the chamber door 3 changes from closed to open, and the closing critical point B is the critical point at which the chamber door 3 changes from open to closed. The sliding component 51 is slidably disposed on the side wall of the excretion container 1 along the first direction and slides synchronously with the grille 21. The sliding component 51 moves to abut against the opening critical point A, and the distance between the vertical lowest point of the grille 21 and the vertical lowest point of the opening is L1. The sliding component 51 moves to abut against the closing critical point B, and the distance between the vertical lowest point of the grille 21 and the vertical lowest point of the opening is L2, where L1 > L2.

[0070] During the fecal collection process, the grille 21 and the sliding component 51 move synchronously. When the sliding component 51 comes into contact with the opening critical point A, the chamber door 3 is about to open. At this time, the distance between the lower edge of the grille 21 and the lower edge of the opening of the fecal collection chamber 11 is L1. The linkage 4 rotates under the action of the sliding component 51. The sliding component 51 can reciprocate between the opening critical point A and the closing critical point B. During the movement of the sliding component 51 from the opening critical point A to the closing critical point B, the chamber door 3 gradually opens until it is fully open, and the grille 21 pushes... Feces are pushed into the collection chamber 11. When the sliding component 51 comes into contact with the closing critical point B, the linkage 4 moves to close the chamber door 3. At this time, the distance between the lower edge of the grille 21 and the lower edge of the opening of the collection chamber 11 is L2, completing one feces collection operation. Where L1>L2, this feces collection device can ensure that the excrement on the grille 21 will not be pushed off the chamber door 3 and fall outside the excrement container 1 during the opening of the collection chamber 11, improving the efficiency of scooping and the cleanliness of the home space, and increasing the pet's usable space when the collection chamber 11 is closed.

[0071] In this embodiment, one end of the linkage 4 is rotatably connected to the excretion vessel 1, and the other end is fixed with a push rod (not shown). The push rod is inserted into a groove on the side wall of the excretion vessel 1 and can slide in the groove along the second direction. When the linkage 4 rotates relative to the excretion vessel 1, the push rod slides along the groove to abut against the lower surface of the chamber door 3 and can drive the chamber door 3 to open.

[0072] In other embodiments, one end of the linkage 4 is rotatably connected to the excrement container 1, and the other end is connected to the door 3 via a movable hinge. When the linkage 4 rotates around the excrement container 1, the door 3 can be directly opened by the movable characteristics of the hinge, resulting in a simpler structure and higher transmission efficiency.

[0073] For ease of description in this embodiment, when the sliding component 51 abuts against the opening critical point A, the position of the grille 21 is defined as the first position, and when the sliding component 51 moves to abut against the closing critical point B, the position of the grille 21 is defined as the second position.

[0074] like Figures 3-8 As shown, the sidewall of the excretory container 1 is provided with a first track 6 and a second track 7 along a first direction, with the first track 6 located above the second track 7. The sliding assembly 51 includes a movable member 510, a mounting base 511, an abutment member 512, and a track mating member 513. The movable member 510 is slidably connected to the sidewall of the excretory container 1, and the mounting base 511 is elastically connected to the movable member 510 so that the mounting base 511 floats along a second direction. The first direction and the second direction form a preset angle. The abutment member 512 and the track mating member 513 are both disposed on the mounting base 511. The track mating member 513 can move along the first track 6 or the second track 7, and the abutment member 512 can abut against the linkage member 4. The movable component 510 is slidably connected to the side wall of the excretion container 1, providing guidance for the sliding assembly 51 to slide in the first direction and ensuring smooth movement. The mounting base 511 is elastically connected to the movable component 510, allowing the mounting base 511 to float in the second direction, thereby allowing the track mating component 513 on the mounting base 511 to slide on the first track 6 or the second track 7, so that the abutment component 512 accurately abuts against the opening critical point A or the closing critical point B, thereby accurately controlling the opening and closing of the compartment door 3. The sliding assembly 51 has a compact overall structure and good fit, ensuring efficient operation of the device.

[0075] In this embodiment, the preset included angle is 90 degrees, that is, the first direction and the second direction are perpendicular to each other. In other embodiments, the preset included angle can be 30 degrees, 60 degrees, 120 degrees, 150 degrees, etc., and no specific limitation is made here.

[0076] In this embodiment, the abutment member 512 can be a roller. The roller is rotatably mounted on the mounting base 511, which can significantly reduce the moving resistance, make the grid 21 move more smoothly, help to collect feces efficiently, and at the same time reduce component wear and extend the service life of the device.

[0077] In this embodiment, the track fitting 513 can be a track wheel, which is rotatably arranged on the mounting base 511, and can improve the smoothness and reliability of the overall operation of the feces collection device.

[0078] In other embodiments, a guide rail is provided on the side wall of the excretion vessel 1. The guide rail is arranged in a "mouth" shape, and the moving member 510 can move along the guide rail. When the moving member 510 moves on the upper horizontal bar of the "mouth" shape, it can abut against the linkage member 4. When the moving member 510 abuts against the opening critical point A, the linkage member 4 is about to rotate and can drive the bin door 3 to open; when the moving member 510 moves downward on the left vertical bar or the right vertical bar of the "mouth" shape, the moving member 510 abuts against the closing critical point B, and the linkage member 4 presses against the moving member 510, and the moving member 510 cannot push the linkage member 4 to rotate, and the bin door 3 gradually closes.

[0079] As Figure 3 shown, the sliding assembly 51 further includes a guide post 514 and an elastic member 515. The guide post 514 extends along the second direction. The moving member 510 is fixedly connected to the guide post 514, and the mounting base 511 is slidably connected to the guide post 514. Two ends of the elastic member 515 are respectively connected or abutted to the moving member 510 of the mounting base 511, and the elastic member 515 can deform along the axial direction of the guide post 514. The guide post 514 extends along the second direction and is fixedly connected to the moving member 510, and the mounting base 511 can slide along the guide post 514, providing guidance for the movement of the mounting base 511 along the second direction and ensuring the stability and accuracy of its movement. Two ends of the elastic member 515 are respectively connected or abutted to the mounting base 511 and the moving member 510, and can deform along the axial direction of the guide post 514, endowing the mounting base 511 with the floating ability along the second direction and effectively buffering external impacts. This structural design not only enhances the adaptability and reliability of the sliding assembly 51, but also ensures good contact between the abutting member 512 and the opening critical point A or the closing critical point B, guarantees the accuracy of the opening and closing control of the bin door 3, and improves the overall performance of the feces collection device.

[0080] In this embodiment, the elastic member 515 is sleeved on the guide post 514. The elastic member 515 is sleeved on the guide post 514, and two ends of the elastic member 515 are respectively connected or abutted to the mounting base 511 and the moving member 510, which can not only make the mounting base 511 float flexibly along the second direction and effectively buffer the impacts and vibrations during work, but also ensure that the elastic member 515 does not shift during deformation by virtue of the limiting effect of the guide post 514, thereby ensuring the normal contact between the abutting member 512 and the opening critical point A or the closing critical point B, and guaranteeing the accuracy of the opening and closing control of the bin door 3 and the efficient operation of the device.

[0081] As Figure 8As shown, the first track 6 has a first clearance opening 61 and a second clearance opening 62 at both ends, allowing the track fitting component 513 to switch between the first track 6 and the second track 7. The track fitting component 513 can switch between the first track 6 and the second track 7 via the first clearance opening 61 and the second clearance opening 62, increasing the flexibility of the sliding component 51's movement. When the track fitting component 513 needs to switch from the second track 7 to the first track 6, or from the first track 6 to the second track 7, the clearance openings provide the necessary space, ensuring a smooth switching process without jamming or obstruction. Simultaneously, it ensures that the abutment component 512 can accurately abut against the opening critical point A or the closing critical point B, achieving precise control of the opening and closing of the compartment door 3 and improving the overall reliability and stability of the device.

[0082] Specifically, when the grille 21 is in the first position, the track fitting 513 moves on the first track 6 and abuts against the upper surface of the first track 6. The abutting part 512 abuts against the opening critical point A, which just pushes the linkage 4 to rotate so that the compartment door 3 is about to open. When the grille 21 is in the second position, the track fitting 513 moves on the second track 7 and abuts against the upper surface of the second track 7. The abutting part 512 abuts against the closing critical point B. The gravity of the linkage 4 presses against the abutting part 512 so that the compartment door 3 is just closed.

[0083] When fecal collection is required, the grille 21 moves from the second position to the first position, and the track fitting 513 moves on the second track 7, rising from the second clearance opening 62 to the first track 6. The track fitting 513 moves on the first track 6 so that the abutment 512 abuts against the opening critical point A, and the chamber door 3 is about to open. The grille 21 moves from the first position to the second position, and the track fitting 513 moves on the first track 6. When it reaches the end position of the first track 6, the abutment 512 abuts against the linkage 4, and the rotation angle increases. The chamber door 3 opens to the maximum position, pushing the feces on the grille 21 into the fecal collection chamber 11. The track fitting 513 falls from the first clearance opening 61 onto the second track 7, and the abutment 512 no longer abuts against the linkage 4. The chamber door 3 closes, completing one fecal collection operation.

[0084] In this embodiment, as Figure 8 As shown, a first guide surface 71 is provided at the first clearance opening 61. The first guide surface 71 is used to guide the track mating component 513 from the first track 6 into the second track 7. This avoids jamming or offset of the track mating component 513 when switching from the first track 6 to the second track 7, ensuring the smooth operation of the sliding component 51.

[0085] In this embodiment, a second guide surface 81 is provided at the second clearance opening 62. The second guide surface 81 is used to guide the track mating component 513 from the second track 7 into the first track 6. This avoids jamming or offset of the track mating component 513 when switching from the second track 7 to the first track 6, ensuring the smooth operation of the sliding component 51.

[0086] In this embodiment, the first guide surface 71 is disposed at the end of the second track 7, and the specific location of the first guide surface 71 is not specifically limited here.

[0087] like Figure 1 , Figure 2 , Figures 9-12 As shown, the excretory container 1 has a collection chamber 11 at each end, and each collection chamber 11 has a door 3. The side wall of the excretory container 1 also has a third track 8 along a first direction, and first tracks 6 are symmetrically arranged at both ends of the third track 8. A linkage 4 is correspondingly arranged above each first track 6. The sliding component 51 can enter any first track 6 along the third track 8 so that the abutment 512 abuts against its corresponding linkage 4. Each door 3 is connected to or abuts against its corresponding linkage 4. Rotation of the linkage 4 can drive the corresponding door 3 to open, thus opening the corresponding collection chamber 11. The excretory container 1 has collection chambers 11 at both ends, and each door 3 corresponds to a linkage 4. The third track 8 on the side wall and the symmetrical first tracks 6 at both ends allow the sliding component 51 to flexibly enter any first track 6 along the third track 8, facilitating the collection of feces at both ends and improving collection efficiency.

[0088] In this embodiment, the second guide surface 81 is disposed at the end of the third track 8, and the specific location of the second guide surface 81 is not specifically limited here.

[0089] like Figures 9-12 As shown, the fecal collection device includes two sliding components 51, which are slidably mounted on opposite side walls of the excrement container 1. The opposite ends of the grid 21 are rotatably connected to the moving parts 510 within the sliding components 51. Firstly, this design allows the sliding components 51 to more effectively drive the grid 21, thereby precisely controlling the opening and closing of the chamber door 3, improving the overall stability and reliability of the device, and ensuring efficient and orderly fecal collection. Secondly, the rotatable connection between the grid 21 and the moving parts 510 increases the flexibility of the grid 21's movement, better adapting to the device's operational needs. The two sliding components 51 ensure even force distribution during the sliding of the grid 21, preventing tilting, jamming, or other issues, making the sliding process of the grid 21 smoother and more stable.

[0090] like Figures 9-12As shown, the fecal collection device also includes a guide rod 22 and a flipping drive 9. One end of the guide rod 22 is connected to the grille 21, and the other end is rotatably connected to the moving part 510. The flipping drive 9 is flip-mounted on the linkage 4, and can selectively change the orientation of the grille 21. The connection method of the guide rod 22 ensures the effective transmission of movement between the grille 21 and the moving part 510, allowing the grille 21 to slide smoothly with the moving part 510. The flipping drive 9 can selectively abut against the guide rod 22. This design gives the grille 21 the function of flipping. When it is necessary to clean or collect feces, the grille 21 can be flexibly flipped so that the grille 21 can push the feces into either of the two collection chambers 11, improving the efficiency of fecal collection. At the same time, this structure makes the various components of the device fit together tightly, enhances the stability and reliability of the device operation, and improves the practicality and ease of operation of the fecal collection device.

[0091] For ease of description, the first direction is divided into the positive direction and the negative direction. Furthermore, the extension direction of the guide rod 22 is defined as the direction from the moving member 510 to the grille 21. The flipping drive member 9 is rotatably mounted on the linkage member 4 in the direction of movement of the grille 21 via a rotating shaft. Initially, the flipping drive member 9 is horizontal. When the flipping drive member 9 is subjected to an upward force, it flips upward. When the flipping drive member 9 is subjected to a downward force, it remains horizontal and does not flip.

[0092] like Figures 9-10 As shown, when the grille 21 moves in the opposite direction of the first direction, and the extension direction of the guide rod 22 is at an obtuse angle to the opposite direction of the first direction, the guide rod 22 can push the flipping drive 9 to flip upward and pass over the flipping drive 9. Under its own gravity, the flipping drive 9 can rotate to the initial horizontal state.

[0093] like Figures 11-12 As shown, when the grille 21 moves in the positive direction of the first direction, and the extension direction of the guide rod 22 forms an acute angle with the positive direction of the first direction, the flipping drive 9 can push the guide rod 22 to flip, thereby changing the direction of the grille 21. At this time, the grille 21 continues to move in the positive direction of the first direction, and the extension direction of the guide rod 22 forms an obtuse angle with the positive direction of the first direction. The guide rod 22 pushes the flipping drive 9 to flip upward and pass over the flipping drive 9. Under its own gravity, the flipping drive 9 can rotate back to its initial horizontal state. This ingenious design eliminates the need for a complex drive structure, utilizing the interaction between components and gravity to achieve effective flipping and direction change of the grille 21, improving the stability and ease of operation of the device.

[0094] In other embodiments, the flipping drive 9 can also be rotatably mounted on the linkage 4 in the direction of movement of the grille 21 by means of a reset spring. The flipping drive 9 can rotate to the initial horizontal state under the action of the reset spring when it is not under force.

[0095] like Figure 6 and Figure 9 As shown, the feces collection device also includes a drive assembly 52 and a slide rail 53. The drive assembly 52 includes a transmission belt 521 and pulleys 522. The movable member 510 is fixedly connected to the transmission belt 521. The pulleys 522 are rotatably mounted on the excrement container 1. The transmission belt 521 is wound around the two pulleys 522 and tensioned by the two pulleys 522. The rotation of the pulleys 522 can drive the transmission belt 521 to move. The slide rail 53 is mounted on the excrement container 1 and extends along the first direction. The movable member 510 is slidably mounted on the slide rail 53. The transmission belt 521 is wound around two tensioned pulleys 522. This structural design makes the power transmission more stable and reliable. The slide rail 53 extending along the first direction on the excretion vessel 1 provides a stable guiding path for the sliding of the moving part 510. When the pulleys 522 rotate, they can effectively drive the transmission belt 521 to move, thereby driving the moving part 510 to move smoothly along the slide rail 53, ensuring the linearity and stability of the movement of the moving part 510. The entire drive assembly 52 has a compact structure and high transmission efficiency, which improves the working performance and reliability of the device.

[0096] In this embodiment, the movable component 510 is provided with a slot (not shown), and the transmission belt 521 is inserted into the slot to fix the movable component 510 on the transmission belt 521. This connection method avoids relative sliding between the movable component 510 and the transmission belt 521 during movement, ensuring that when the pulley 522 rotates, the transmission belt 521 can reliably drive the movable component 510 to move along the slide rail 53, thereby making the sliding component 51 operate stably, improving the reliability and stability of the entire fecal collection device, and ensuring the normal operation of the device.

[0097] like Figure 6 and Figure 9 As shown, the drive assembly 52 also includes a drive motor 523, which is connected to one of the pulleys 522. The drive motor 523, as a power source, provides a stable and continuous power output to the pulley 522, thereby driving the transmission belt 521 wound around the pulley 522. This drives the moving part 510, which is fixedly connected to the transmission belt 521, to slide along the slide rail 53, ensuring the normal operation of the sliding assembly 51. This transmission connection method makes power transmission direct and efficient, reducing energy loss. Specifically, two pulleys 522 are rotatably arranged on both sides of the excrement container 1, and the transmission belts 521 on both sides are wound around the corresponding two pulleys 522.

[0098] In this embodiment, the drive motor 523 is a single-axis output motor. A first gear is installed at the output end of the single-axis output motor. The excrement container 1 also includes a connecting shaft. One end of the connecting shaft is connected to either of the two pulleys 522 on one side of the excrement container 1, and the other end is connected to either of the two pulleys 522 on the other side of the excrement container 1. A second gear is fixed on the connecting shaft. The first gear meshes with the second gear. When the single-axis output motor drives the first gear to rotate, the first gear drives the meshing second gear to rotate, which in turn drives the connecting shaft to rotate, so that the two pulleys 522 rotate synchronously, and the transmission belts 521 on both sides move synchronously. This design avoids abnormal operation of the grille 21 due to asynchronous power on both sides, enhancing the stability of the device operation. Simultaneously, the use of gear transmission results in a compact structure, accurate transmission ratio, reduced power loss, and improved overall performance and reliability of the feces collection device.

[0099] In some embodiments, the drive motor 523 is a dual-axis output motor. One of the two output terminals of the dual-axis output motor is connected to either of the two pulleys 522 on one side of the excrement container 1, and the other output terminal is connected to either of the two pulleys 522 on the other side of the excrement container 1. The dual-axis output motor can simultaneously drive the two pulleys 522 to rotate synchronously. This causes the moving parts 510 on both sides of the excrement container 1 to move synchronously, driving the grille 21 to slide smoothly. This design avoids problems such as tilting and jamming of the grille 21 caused by uneven power on both sides, improving the stability of the device operation.

[0100] In this embodiment, a position sensor (not shown) is also provided on the side wall of the excretion container 1. The position sensor can receive the position information of the track fitting 513. When the abutment 512 abuts against the closing critical point B, the position sensor transmits the position information of the track fitting 513 to the drive motor 523. The drive motor 523 drives the pulley 522 to move in the opposite direction, so that the transmission belt 521 moves in the opposite direction, driving the moving part 510 to move in the opposite direction as a whole.

[0101] like Figures 13-15 As shown, the process of the grille 21 moving from the first position to the second position is roughly as follows:

[0102] like Figure 13 As shown, when the grille 21 is in the first position, the track fitting 513 moves in the positive direction along the first direction on the first track 6. At this time, the abutment 512 abuts against the opening critical point A on the linkage 4, and the track fitting 513 abuts against the upper surface of the first track 6. The abutment 512 is about to push the linkage 4 to rotate, and the rotation of the linkage 4 will cause the compartment door 3 to open.

[0103] like Figure 14 As shown, the grille 21 moves forward along the first direction from the first position, and the distance between the grille 21 and the collection chamber 11 gradually shortens. The track fitting 513 continues to move forward along the first direction on the first track 6. The abutment 512 continuously pushes the linkage 4 to rotate, and the rotation angle of the linkage 4 gradually increases. When the track fitting 513 moves to the first end of the first track 6, the chamber door 3 is fully opened, and the grille 21 collects the feces into the collection chamber 11.

[0104] like Figure 15 As shown, when the grille 21 reaches the second position, the abutting part 512 abuts against the closing critical point B on the linkage part 4, and the track fitting part 513 falls from the first clearance opening 61 on the first track 6 to the second track 7. At this time, the abutting part 512 is subjected to the gravity of the linkage part 4, the mounting base 511 descends, the abutting part 512 no longer pushes the linkage part 4 to rotate, the bin door 3 closes, and the fecal collection work is completed.

[0105] like Figures 16-20 As shown, the process of the grille 21 moving from the second position to the first position is roughly as follows:

[0106] like Figure 16 As shown, when it is necessary to collect feces again, the grille 21 moves in the opposite direction from the second position along the first direction, the distance between the grille 21 and the collection chamber 11 gradually increases, the track mating part 513 moves in the opposite direction along the first direction on the second track 7, at this time the abutment part 512 gradually moves away from the linkage part 4, and the chamber door 3 always remains closed.

[0107] like Figure 17 As shown, the track fitting 513 continues to move in the opposite direction along the first direction on the second track 7, and moves to the second end of the first track 6, where the track fitting 513 abuts against the lower surface of the second end of the first track 6.

[0108] like Figure 18 As shown, the grille 21 moves to the middle position of the excretion container 1, and the track fitting 513 continues to move in the opposite direction along the first direction on the second track 7. The track fitting 513 abuts against the lower surface of the second guide surface 81, and the grille 21 can push the feces at the middle position of the excretion container 1.

[0109] like Figure 19 As shown, the grille 21 moves in the opposite direction of the first direction, and the track mating part 513 abuts against the lower surface of the third track 8.

[0110] like Figure 20As shown, the grille 21 moves towards the first position in the positive direction of the first direction. The track fitting 513 rises from the second clearance opening 62 onto the first track 6. The track fitting 513 moves along the first direction in the positive direction on the first track 6. The abutment 512 just abuts against the linkage 4, but at this time the abutment 512 is not subjected to the gravity of the linkage 4. The height of the mounting base 511 remains unchanged, and the track fitting 513 does not contact the upper surface of the first track 6. The grille 21 then moves to the first position and repeats the process. Figure 13 The process is shown.

[0111] It is understood that the above process is the process of collecting feces in one of the two feces collection chambers 11. The process of collecting feces in the other feces collection chamber 11 is the same as the above process, and will not be described in detail here.

[0112] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
