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 during the opening of the collection chamber, 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.

[0006] To achieve this objective, the present invention adopts the following technical solution:

Critical point B, the opening critical point A is the critical point at which the door changes from closed to open, and the closing critical point B is the critical point at which the door changes from open to closed; sliding component, the sliding component is slidably disposed on the side wall of the excrement container along the first direction and slides synchronously with the grille; the sliding component moves to abut against the opening critical point A, the distance between the vertical lowest point of the grille and the vertical lowest point of the opening is L1, the sliding component moves to abut against the closing critical point B, the distance between the vertical lowest point of the grille and the vertical lowest point of the opening is L2, where L1 > L2.

[0008] As an alternative, the sliding component includes: a movable member slidably connected to the side wall of the excretory container; and an abutment member elastically connected to the movable member to allow the abutment member to float along a second direction, the second direction forming a preset angle with the first direction, the abutment member being able to abut against the first track and move along the first track; or; the abutment member being able to abut against the second track and move along the second track.

[0009] As an optional solution, the sliding assembly further includes: a fixing member, the first end of which is fixedly connected to the moving member; a guide post, which extends along the second direction, the second end of which is provided with the guide post, the guide post passing through the abutment member and fixedly connected to the moving member, the abutment member being able to move along the axial direction of the guide post; and an elastic member, the two ends of which are respectively connected to or abut against the moving member and the abutment member, and the elastic member being able to deform along the axial direction of the guide post.

[0010] As an alternative, the two ends of the second track are respectively provided with a first clearance opening and a second clearance opening, so that the abutment can be switched to the first track or to the second track.

[0011] As an alternative, the end of the first track is provided with a guide portion for guiding the abutment from the first track into the second track.

[0012] As an alternative, the second track is a zigzag track, which includes a first bend, a second bend, and a third bend. The two ends of the second bend are connected to the first bend and the third bend, respectively, and there is a height difference between the first connection point of the first bend and the second bend and the second connection point of the second bend and the third bend.

[0013] As an alternative, the excretory container has a collection chamber at each end, and each collection chamber has a door. The side wall of the excretory container is also provided with a third track along the first direction. The two ends of the third track are symmetrically provided with linkage members. The abutment member can enter the first track on any of the linkage members along the third track so that the abutment member abuts against its corresponding linkage member. Each collection chamber door is connected to or abuts against its corresponding linkage member.

The drive belt is wound around two of the pulleys and tensioned by the two pulleys. The rotation of the pulleys can drive the drive belt to move. The slide rail is mounted on the excrement container and extends along the first direction. The moving member is slidably mounted on the slide rail.

[0019] Beneficial effects:

[0020] This invention provides a feces collection device. During the feces collection process, the grid 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 lowest vertical point of the grid and the lowest vertical point 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 grid 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 about to close. At this time, the distance between the lowest vertical point of the grid and the lowest vertical point of the opening of the collection chamber is L2. The chamber door closes to complete one feces collection operation, where L1>L2. This feces collection device can ensure that the excrement on the grid 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.

[0049] This embodiment provides a fecal collection device, such as... Figures 1-10As shown, the fecal collection device includes a discharge vessel 1, a chamber door 3, a linkage 4, and a sliding assembly 5. 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 installed 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 is connected to or abuts against the lower surface of the chamber door 3. The linkage 4 is provided with a first track 41 and a second track 42. The first track 41 is located below the second track 42. An opening critical point A is provided on the first track 41, and a closing critical point B is provided on the second track 42. 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 5 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 5 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 5 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.

[0050] In the fecal collection device provided in this embodiment, during the fecal collection process, the grille 21 and the sliding component 5 move synchronously. When the sliding component 5 abuts against the opening critical point A, the chamber door 3 is about to open. At this time, the distance between the lowest vertical point of the grille 21 and the lowest vertical point of the opening of the fecal collection chamber 11 is L1. The linkage 4 rotates under the action of the sliding component 5. The sliding component 5 can reciprocate between the opening critical point A and the closing critical point B. During the movement of the sliding component 5 from the opening critical point A to the closing critical point B, the chamber door 3 gradually opens until it is fully open. When the feces are pushed into the collection chamber 11, the sliding component 5 comes into contact with the closing critical point B, and the linkage 4 moves to close the chamber door 3. At this time, the distance between the lowest vertical point of the grille 21 and the lowest vertical point of the opening of the collection chamber 11 is L2. The chamber door 3 closes to complete 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 excrement container 1 by the chamber door 3 during the opening of the collection chamber 11, thus 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.

[0051] 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.

[0052] 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.

[0053] like Figure 3 , Figures 6-10 As shown, the sliding component 5 includes a movable member 51 and an abutment member 52. The movable member 51 is slidably connected to the side wall of the excretion container 1, and the abutment member 52 is elastically connected to the movable member 51, allowing the abutment member 52 to float along a second direction. The second direction forms a preset angle with the first direction. The abutment member 52 can abut against the first track 41 and move along the first track 41, or the abutment member 52 can abut against the second track 42 and move along the second track 42. The elastic connection between the abutment member 52 and the movable member 51, allowing the abutment member 52 to float along the second direction, better adapts to the first track 41 and the second track 42 on the linkage member 4, enabling the abutment member 52 to slide along the first track 41 or the second track 42. This allows the abutment member 52 to accurately abut against the opening critical point A or the closing critical point B, thereby accurately controlling the opening of the compartment door 3. The elastic connection also effectively buffers the impact and reduces wear.

[0054] 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.

[0055] like Figures 4-5 As shown, the sliding assembly 5 also includes a fixing member 53, a guide post 54, and an elastic member 55. The first end of the fixing member 53 is fixedly connected to the moving member 51. The guide post 54 extends along the second direction, and the second end of the fixing member 53 is provided with the guide post 54. The guide post 54 passes through the abutment member 52 and is fixedly connected to the moving member 51. The abutment member 52 can move along the axial direction of the guide post 54. The two ends of the elastic member 55 are connected to or abut against the moving member 51 and the abutment member 52, respectively, and the elastic member 55 can deform along the axial direction of the guide post 54. The fixing member 53 firmly connects the moving member 51 and the guide post 54, ensuring the integrity of the structure. The guide post 54 extends along the second direction and passes through the abutment member 52, providing precise guidance for the axial movement of the abutment member 52, enabling it to move stably along the first track 41 or the second track 42, accurately touching the opening critical point A and the closing critical point B, thus realizing the precise opening and closing of the compartment door 3.

[0056] In this embodiment, the abutment 52 is a roller. The roller can rotate relative to the guide post 54, which can significantly reduce the moving resistance of the moving part 51, making the grid 21 move more smoothly and efficiently collect feces. At the same time, it reduces the wear between the abutment 52 and the first track 41 or the second track 42, and extends the service life of the feces collection device.

[0057] In this embodiment, the elastic element 55 is sleeved on the guide post 54, and the two ends of the elastic element 55 abut against the moving element 51 respectively. This not only allows the abutting element 52 to float flexibly along the second direction, effectively buffering impact and vibration, but also restricts the position of the elastic element 55, ensuring that the elastic element 55 will not shift when deformed. This ensures normal contact between the abutting element 52 and the opening critical point A and closing critical point B, ensuring the accuracy of the opening and closing control of the chamber door 3, and thus ensuring the efficient operation of the fecal collection device.

[0058] Optionally, the elastic element 55 can be a spring, a rubber component, etc., without specific limitations.

[0059] like Figure 4 As shown, the sliding assembly 5 also includes a connecting post 56 and a fastener 57. The first end of the fixing member 53 is provided with the connecting post 56, which has an internal thread. The moving member 51 has a through hole, through which the connecting post 56 passes. Optionally, the fastener 57 is a screw, which is screwed into the connecting post 56 and threadedly connected to it. The nut of the screw abuts against the side of the moving member 51 away from the fixing member 53 to fix the fixing member 53 and the moving member 51 together. The connection method between the fixing member 53 and the moving member 51 can also be welding, which is not specifically limited here.

[0060] In this embodiment, the guide post 54 is provided with an internal thread, the abutment member 52 is provided with a through hole, and the movable member 51 is also provided with a through hole corresponding to the through hole. The guide post 54 is provided with the through hole, the elastic member 55 and the through hole in sequence. Optionally, the fastener 57 is a screw. The screw is screwed into the guide post 54 and threadedly connected to the guide post 54. The nut of the screw abuts against the side of the movable member 51 away from the fixed member 53, so as to clamp the abutment member 52 between the fixed member 53 and the movable member 51, and limit the floating range of the abutment member 52 in the second direction.

[0061] In this embodiment, the fixing member 53 is constructed as a triangle, with one apex pointing vertically upwards and the other two apexes at the same horizontal level. The guide post 54 is located on the upper apex of the fixing member 53, and connecting posts 56 are located on the other two apexes. This structure stabilizes the fixing member 53, thereby ensuring the relative stability of the abutment member 52 and improving the overall stability of the sliding assembly 5. In other embodiments, the fixing member 53 can also be constructed as a rectangle, trapezoid, or irregular shape, and multiple connecting posts 56 can be provided, as long as the fixing member 53 and the moving member 51 are stably connected and the position of the abutment member 52 is relatively stable; no specific limitation is made here.

[0062] like Figure 8 and Figure 10 As shown, the two ends of the second track 42 are respectively provided with a first clearance opening 421 and a second clearance opening 422, so that the abutment member 52 can be switched to the first track 41 or the second track 42. The abutment member 52 can be switched from the first track 41 to the second track 42 through the first clearance opening 421, and the abutment member 52 can be switched from the second track 42 to the first track 41 through the second clearance opening 422, so as to avoid jamming or obstruction.

[0063] like Figures 6-10 As shown, a guide portion 411 is provided at the end of the first track 41. The guide portion 411 is used to guide the abutment member 52 from the first track 41 into the second track 42. The guide portion 411 can guide the abutment member 52 to transition to the second track 42, which improves the continuity of the operation of the fecal collection device and avoids jamming or derailment of the abutment member 52 when switching tracks. At the same time, the guide portion 411 reduces the collision and wear of the abutment member 52 caused by switching tracks, extends the service life of the abutment member 52, the first track 41 and the second track 42, and ensures the long-term stable operation of the fecal collection device.

[0064] In this embodiment, the guide part 411 is constructed in a ramp shape so that when the abutment 52 moves along the first direction on the first track 41, the elastic member 55 is in a naturally extended state. The abutment 52 slides from the first track 41 along the ramp-shaped guide part 411 to the second track 42, at which time the elastic member 55 is compressed along the second direction.

[0065] For ease of description in this embodiment, the first direction is divided into the positive direction and the negative direction. For example... Figures 7-8As shown, when the abutting member 52 abuts against the first track 41 and moves in the positive direction of the first direction, the linkage 4 rotates, and the compartment door 3 gradually opens. At this time, the elastic member 55 is in a naturally extended state, and the side of the abutting member 52 abuts against the ramp-shaped guide part 411, guiding the abutting member 52 from the first clearance opening 421 to switch from the first track 41 to the second track 42. At this time, the abutting member 52 moves in the second direction, and the elastic member 55 is compressed in the second direction. Figures 9-10 As shown, the abutting member 52 abuts against the second track 42 and moves in the opposite direction of the first direction. When the abutting member 52 abuts against the closing critical point B, the door 3 is about to close. The abutting member 52 continues to move in the opposite direction of the first direction. The door 3 closes and moves away from the second track 42 through the second clearance opening 422. The elastic member 55 extends and pushes the abutting member 52 to move in the second direction so that the abutting member 52 can abut against the first track 41 again.

[0066] like Figures 6-10 As shown, the second track 42 is a zigzag track, which includes a first bend 423, a second bend 424, and a third bend 425. The two ends of the second bend 424 are connected to the first bend 423 and the third bend 425, respectively. There is a height difference between the first connection point of the first bend 423 and the second bend 424 and the second connection point of the second bend 424 and the third bend 425. The height difference between the first connection point and the second connection point causes the linkage 4 to rotate rapidly due to gravity when the abutment 52 moves away from the first bend 423, causing the chamber door 3 to close quickly, ensuring that the waste collection chamber 11 is sealed in time, and reducing the risk of odor emission and fecal leakage.

[0067] like Figure 10 As shown, when the abutting member 52 abuts against the second track 42 and moves in the opposite direction of the first direction, it moves a certain distance after passing through the gentle first bend 423. There is a certain distance between the lowest vertical point of the grille 21 and the lowest vertical point of the opening of the collection chamber 11. That is, after the grille 21 pushes the feces into the collection chamber 11, it moves a certain distance in the opposite direction. This distance is less than L2, so as to prevent the grille 21 from extending into the collection chamber 11 when the chamber door 3 is closed, which would affect the normal closing of the chamber door 3 and the use of the feces collection device. The abutting member 52 continues to move in the opposite direction of the first direction and abuts against the closing critical point B. Because there is a height difference between the first connection point and the second connection point, when the abutting member 52 moves away from the first bend 423, the linkage 4 can rotate quickly under the action of gravity to drive the chamber door 3 to close. Subsequently, the abutting member 52 can continue to abut against the third bend 425 and move in the opposite direction of the first direction.

[0068] like Figures 1-3As 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 6 along a first direction. The two ends of the third track 6 are symmetrically equipped with linkages 4. Abutment members 52 can enter the first track 41 of any linkage member 4 along the third track 6, so that the abutment member 52 abuts against its corresponding linkage member 4. Each door 3 is connected to or abuts against its corresponding linkage member 4. Rotation of the linkage member 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 member 4. The third track 6 on the side wall is connected to the symmetrical first tracks 41 at both ends. The abutment member 52 can flexibly enter any first track 41 along the third track 6, facilitating the collection of feces at both ends and improving collection efficiency.

[0069] like Figure 3 , Figure 7 , Figure 9 As shown, the fecal collection device includes two sliding components 5, 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 51 within the sliding components 5. Firstly, this design allows the sliding components 5 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 51 increases the flexibility of the grid 21's movement, better adapting to the device's operational needs. The two sliding components 5 ensure even force distribution during the sliding of the grid 21, preventing tilting or jamming, and making the sliding process of the grid 21 smoother and more stable.

[0070] like Figures 11-20 As shown, the fecal collection device also includes a guide rod 22 and a flipping drive 7. One end of the guide rod 22 is connected to the grille 21, and the other end is rotatably connected to the moving part 51. The flipping drive 7 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 51, allowing the grille 21 to slide smoothly with the moving part 51. The flipping drive 7 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.

[0071] For ease of description in this embodiment, the extension direction of the guide rod 22 is defined as the direction from the moving member 51 to the grille 21. The flipping drive member 7 is rotatably mounted on the linkage member 4 in the direction of movement of the grille 21 via a rotating shaft. The flipping drive member 7 is initially in a horizontal state. When the flipping drive member 7 is subjected to an upward force, it will flip upward. When the flipping drive member 7 is subjected to a downward force, it will remain in a horizontal state and will not flip.

[0072] like Figures 11-17 As shown, when the grille 21 moves in the positive direction of the first direction and the extension direction of the guide rod 22 is at an obtuse angle to the positive direction of the first direction, the guide rod 22 can push the flipping drive 7 to flip upward and pass over the flipping drive 7. Under its own gravity, the flipping drive 7 can rotate to the initial horizontal state.

[0073] like Figures 18-20 As shown, when the grille 21 moves in the opposite direction of the first direction, the extension direction of the guide rod 22 forms an acute angle with the opposite direction of the first direction. The flipping drive 7 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 opposite 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 7 to flip upward and pass over the flipping drive 7. Under its own gravity, the flipping drive 7 can rotate back to its initial horizontal state. This ingenious design eliminates the need for a complex drive structure. By utilizing the interaction between components and gravity, it achieves effective flipping and direction changing of the grille 21, improving the stability and ease of operation of the device.

[0074] In other embodiments, the flipping drive 7 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 7 can rotate to the initial horizontal state under the action of the reset spring when it is not under force.

[0075] like Figure 7 , Figure 9 and Figure 16As shown, the fecal collection device also includes a drive assembly 8 and a slide rail 9. The drive assembly 8 includes a transmission belt 81 and pulleys 82. The moving part 51 is fixedly connected to the transmission belt 81. The pulleys 82 are rotatably mounted on the excrement container 1. The transmission belt 81 is wound around the two pulleys 82 and tensioned by the two pulleys 82. The rotation of the pulleys 82 can drive the transmission belt 81 to move. The slide rail 9 is mounted on the excrement container 1 and extends along a first direction. The moving part 51 is slidably mounted on the slide rail 9. The transmission belt 81 is wound around the two tensioned pulleys 82. This structural design makes the power transmission more stable and reliable. The slide rail 9, which extends along the first direction on the excrement container 1, provides a stable guiding path for the sliding of the moving part 51. When the pulleys 82 rotate, they can effectively drive the transmission belt 81 to move, thereby driving the moving part 51 to move smoothly along the slide rail 9, ensuring the linearity and stability of the moving part 51's movement. The entire drive assembly 8 has a compact structure and high transmission efficiency, improving the working performance and reliability of the device.

[0076] In this embodiment, the movable component 51 is provided with a slot, and the transmission belt 81 is inserted into the slot to fix the movable component 51 on the transmission belt 81. This connection method avoids relative sliding between the movable component 51 and the transmission belt 81 during movement, ensuring that when the pulley 82 rotates, the transmission belt 81 can reliably drive the movable component 51 to move along the slide rail 9, thereby making the sliding component 5 operate stably, improving the reliability and stability of the entire fecal collection device, and ensuring the normal operation of the device.

[0077] like Figure 7 As shown, the drive assembly 8 also includes a drive motor 83, which is connected to one of the pulleys 82. The drive motor 83, as a power source, provides a stable and continuous power output to the pulley 82, thereby driving the transmission belt 81 wound around the pulley 82. This drives the movable part 51, which is fixedly connected to the transmission belt 81, to slide along the slide rail 9, ensuring the normal operation of the sliding assembly 5. This transmission connection method makes power transmission direct and efficient, reducing energy loss. Specifically, two pulleys 82 are rotatably arranged on both sides of the excrement container 1, and the transmission belts 81 on both sides are wound around the corresponding two pulleys 82.

[0078] In this embodiment, the drive motor 83 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 82 on one side of the excrement container 1, and the other end is connected to either of the two pulleys 82 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 82 rotate synchronously, and the transmission belts 81 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.

[0079] In some embodiments, the drive motor 83 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 82 on one side of the excrement container 1, and the other output terminal is connected to either of the two pulleys 82 on the other side of the excrement container 1. The dual-axis output motor can simultaneously drive the two pulleys 82 to rotate synchronously. This causes the moving parts 51 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.

[0080] 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 abutment member 52. When the abutment member 52 is switched to the end position of the second track 42 by the guide part 411, the position sensor transmits the position information of the abutment member 52 to the drive motor 83. The drive motor 83 drives the pulley 82 to move in the opposite direction, so that the transmission belt 81 moves in the opposite direction, and drives the sliding component 5 to move in the opposite direction as a whole.

[0081] For ease of description in this embodiment, when the abutting member 52 abuts against the opening critical point A, the compartment door 3 is in a closed state and is about to open. At this time, the distance between the lowest vertical point of the grille 21 and the lowest vertical point of the opening of the feces collection compartment 11 on one side is L1; when the abutting member 52 abuts against the closing critical point B, the compartment door 3 is in an open state and is about to close. At this time, the distance between the lowest vertical point of the grille 21 and the lowest vertical point of the opening of the feces collection compartment 11 on one side is L2, where L1>L2.

[0082] like Figures 11-15 As shown, the process of the compartment door 3 opening from closed is roughly as follows:

[0083] like Figure 11As shown, the abutting part 52 abuts against the second track 42 and moves in the positive direction along the first direction. After passing the closing critical point B, the linkage 4 rotates rapidly, and the compartment door 3 is in the closed state.

[0084] like Figure 12 As shown, the abutment 52 moves in the positive direction along the first direction and disengages from the second track 42 through the second clearance opening 422.

[0085] like Figure 13 As shown, the abutting member 52 continues to move in the positive direction of the first direction. The abutting member 52 is no longer subjected to the pressure of the second direction, and the elastic member 55 naturally extends to push the abutting member 52 to switch to the first track 41.

[0086] like Figure 14 As shown, the abutting member 52 abuts against the first track 41 and moves in the positive direction of the first direction. The first track 41 is connected to the third track 6. The abutting member 52 switches to abutting against the third track 6 and continues to move in the positive direction of the first direction. The grille 21 pushes the feces toward the corresponding collection chamber 11. At this time, the two chamber doors 3 of the collection chambers on both sides are closed.

[0087] like Figure 15 As shown, the abutting member 52 abuts against the third track 6 and moves in the positive direction along the first direction. The abutting member 52 switches from the third track 6 to the first track 41 and abuts against the opening critical point A. The corresponding compartment door 3 is about to open. At this time, the distance between the vertical lowest point of the grille 21 and the vertical lowest point of the opening of the collection compartment 11 is L1.

[0088] like Figures 16-20 As shown, the process of opening and closing the compartment door 3 is roughly as follows:

[0089] like Figure 16 As shown, the abutting member 52 abuts against the first track 41 and moves in the positive direction of the first direction, pushing the linkage member 4 to rotate so that the corresponding compartment door 3 opens, and the grille 21 pushes the feces into the corresponding collection compartment 11.

[0090] like Figure 17 As shown, the abutting member 52 abuts against the first track 41 and moves in the positive direction along the first direction. When the abutting member 52 moves to the end of the first track 41, the linkage member 4 rotates to the maximum angle and the chamber door 3 is fully opened. The grille 21 collects the feces into the corresponding collection chamber 11.

[0091] like Figure 18 As shown, the abutting member 52 abuts against the first track 41 and moves in the positive direction along the first direction. It is guided by the guide part 411 to switch to the second track 42 and moves away from the first track 41 through the first clearance opening 421.

[0092] like Figure 19As shown, the abutting part 52 abuts against the second track 42 and moves in the opposite direction of the first direction. The abutting part 52 abuts against the closing critical point B, and the compartment door 3 is about to close. At this time, the distance between the vertical lowest point of the grille 21 and the vertical lowest point of the opening of the collection compartment 11 is L2, and L1>L2.

[0093] like Figure 20 As shown, the abutting member 52 abuts against the second track 42 and moves in the opposite direction of the first direction. Because there is a height difference between the first connection point of the first bend 423 and the second bend 424 and the second connection point of the second bend 424 and the third bend 425, when the abutting member 52 moves from the first bend 423 to the second bend 424, the linkage member 4 rotates quickly and the compartment door 3 closes.

[0094] The abutment member 52 continues to abut against the third bend 425 and moves in the opposite direction of the first direction. The extension direction of the guide rod 22 forms an acute angle with the opposite direction of the first direction. The flipping drive member 7 can push the guide rod 22 to flip, so that the grid 21 changes direction, completing one fecal collection operation. When performing fecal collection again, the abutment member 52 continues to move in the opposite direction of the first direction. It can be understood that the above process is the fecal collection process of one of the two fecal collection chambers 11. The fecal collection process of the other fecal collection chamber 11 is the same as the above process, and will not be described in detail here.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
