Description

Technical Field

[0001] The embodiments of the present invention belong to the field of pet supplies, and specifically relate to a pet litter box and a method for controlling the pet litter box. Background Technology

[0002] As people's material living standards continue to improve, their demands for spiritual life are also gradually increasing, leading to a growing number of people who enjoy keeping pet cats and dogs. Many cat and dog lovers adore their pets and even purchase dedicated pet cabins for them. While most pet cabins now come equipped with litter boxes for cats and dogs to use, this trend is not universally accepted.

[0003] While existing litter boxes have largely solved the problem of pet waste disposal when pets and humans live together, they still have many shortcomings. For example, some litter boxes, although designed to hold fine pet litter, often mix the waste with the litter after a pet eliminates, making cleaning tedious and preventing the litter from being reused. Other litter boxes can be flipped after use to separate waste from the litter, allowing for reuse. However, to prevent litter from spilling out during the flipping process, the opening for pets to enter and exit is usually small, making it less user-friendly for pets.

[0004] Furthermore, while existing litter boxes can separate pet litter from excrement by flipping the bowl, the fine litter cannot completely return to the toilet area during the litter return process after the excrement is emptied. Additionally, if the litter box is not cleaned promptly after the pet has finished defecating, a strong odor will develop inside. Summary of the Invention

[0005] The purpose of this invention is to design a pet litter box and a method for controlling the pet litter box, which can separate pet litter and pet excrement or waste while also making it convenient for pets to enter and exit the pet litter box.

[0006] To achieve the above objectives, embodiments of the present invention provide a pet litter box, comprising:

[0007] A base having a cavity, and an opening communicating with the cavity is provided on the top side of the base;

[0008] A basin body is disposed within the cavity of the base, and the basin body is provided with a basin opening, which is disposed on the top side of the basin body;

[0009] The basin body includes: a basin bottom opposite to the basin opening, and a basin wall arranged circumferentially around the basin bottom;

[0010] The base includes: a shell bottom opposite to the opening, and a closed shell wall arranged circumferentially around the shell bottom, the shell wall forming a cavity on the shell bottom.

[0011] In addition, embodiments of the present invention also provide a method for controlling a pet litter box, the method being applied to the pet litter box described above, the method comprising the following steps:

[0012] According to the received drive command, the pet litter box body is driven to rotate around a preset axis as the pivot axis; wherein, the rim of the litter box is used to intersect with the opening of the base on which the litter box is placed when the litter box body rotates, and the angle formed by the intersection of the rim of the litter box body and the opening changes as the litter box body rotates.

[0013] Compared to the prior art, the embodiments of this invention feature a base with a cavity, and an opening communicating with the cavity on the top side of the base. The basin is disposed within the cavity of the base, with its opening located on the top side. This ensures that the pet can only enter the basin from the top and cannot enter from other parts of the base, effectively preventing the pet from being trapped. Furthermore, since the basin can rotate around a preset axis, and when the basin rotates around this axis, the opening of the basin can intersect with the opening of the base, and the angle formed by the opening and the opening changes with the rotation of the basin, both the opening of the basin and the opening of the base have a large size, while also providing a foundation for separating pet litter from pet excrement or waste.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0068] Example 1

[0069] Some embodiments of the present invention relate to a pet litter box, such as... Figure 1 and Figure 2 As shown, it includes: a base 1 and a basin 2. The base 1 has a cavity 11, and is combined with... Figure 6A As shown, the top side of the base 1 is provided with an opening 12 that communicates with the cavity 11.

[0070] Secondly, combining Figure 5A As shown, the basin 2 is disposed within the cavity 11 of the base 1. Furthermore, in this embodiment, as... Figures 6A to 8A As shown, the basin body 2 is provided with a basin opening 21, which is located on the top side of the basin body 2, and, combined with Figure 1 and Figure 2 As shown, the basin body 2 includes: a basin bottom 22 opposite to the basin opening 21, and a basin wall 23 arranged circumferentially around the basin bottom 22.

[0071] Additionally, in some embodiments, such as Figure 1 and Figure 2 As shown, the base 1 includes: a shell bottom 13 opposite to the opening 12, and a closed shell wall 14 arranged circumferentially around the shell bottom 13, the shell wall 14 forming a closed cavity 11 on the shell bottom 13. A first clearance gap 111 is formed between the basin wall 23 and the shell wall 14 to allow the basin 2 to rotate. This first clearance gap 111 prevents the shell wall 14 of the base from interfering with the rotation of the basin 2 when it rotates.

[0072] As can be seen from the above, the base 1 has a cavity 11, and the top side of the base 1 is provided with an opening 12 that connects to the cavity 11. At the same time, the basin 2 is provided inside the cavity 11 of the base 1, and the opening 21 of the basin 2 is provided on the top side of the basin 2, so that the pet can only enter the basin 2 from the top of the basin 2, and cannot enter the basin 2 from other parts of the base 1, thereby effectively preventing the pet from being trapped.

[0073] Additionally, in some embodiments, such as Figures 7A to 8A As shown, the basin 2 can rotate around a preset axis. Furthermore, the basin opening 21 is designed to intersect with the opening 12 when the basin 2 rotates, and the angle formed by the intersection of the basin opening 21 and the opening 12 changes as the basin 2 rotates. This allows both the basin opening 21 and the opening 12 of the base 1 of the pet litter box to have a large size, while also laying the foundation for the separation of pet litter and pet excrement or waste.

[0074] Specifically, in some embodiments, such as Figures 6A to 8A As shown, the rim 21 is positioned in the direction that intersects with the opening 12 when the basin body 2 rotates, and is along the length of the rim 21. Furthermore, in conjunction with... Figure 2 and Figure 9 As shown, the basin wall 23 includes: a first sidewall 231 and a second sidewall 232 disposed opposite to each other along the length direction of the basin opening 21, and a third sidewall 233 and a fourth sidewall 234 disposed opposite to each other along the width direction of the basin opening 21. Similarly, as Figure 2 As shown, the opening 12 is used to intersect the basin opening 21 when the basin body 2 rotates, and is in the length direction of the opening 12. Furthermore, the shell wall 14 includes: a first side plate 141 and a second side plate 142 disposed opposite each other along the length direction of the opening 12, and a third side plate 143 and a fourth side plate 144 disposed opposite each other along the width direction of the basin opening 21. Wherein, as... Figure 2 As shown, the first sidewall 231 and the first side plate 141 are disposed opposite to each other, while the second sidewall 232 and the second side plate 142 are disposed opposite to each other. Simultaneously, the third sidewall 233 and the third side plate 143 are disposed opposite to each other, and the fourth sidewall 234 and the fourth side plate 144 are disposed opposite to each other. This allows a first clearance gap 111 to be formed between the first sidewall 231 and the first side plate 141, between the second sidewall 232 and the second side plate 142, between the third sidewall 233 and the third side plate 143, and between the fourth sidewall 234 and the fourth side plate 144.

[0075] Furthermore, in some embodiments, such as Figure 2 and Figure 5AAs shown, to further prevent the base 1 from interfering with the basin 2 when it rotates, the side of the first side plate 141 facing the cavity 11 and the side of the second side plate 142 facing the cavity 11 are both concave arc surfaces. Simultaneously, corresponding to the first side plate 141, at least a portion of the first side wall 231 extends and bends towards the first side plate 141 from the basin opening 21 to the basin bottom 22. Similarly, as... Figure 2 As shown, corresponding to the second side plate 142, the second side wall 232 extends from the bowl opening 21 to the bowl bottom 22, with at least a portion bending and extending towards the second side plate 142. This allows for a smaller gap between the shell wall 14 of the base 1 and the bowl wall 23 of the bowl 2 without affecting the rotation of the bowl body 2, effectively preventing pets from getting stuck in the gap between the bowl body 2 and the base 1. Furthermore, in some embodiments, such as... Figure 9 As shown, part of the basin wall 23 bends outward from the basin opening 21 to the basin bottom 22 to form a skirt 24, which allows the user to easily rotate the basin body 2.

[0076] Additionally, in other embodiments, such as Figure 5A and Figure 9 As shown, a filter element 3 is installed inside the basin 2, dividing the space within the basin 2 into a toilet area 25 for holding pet litter and a litter storage area 26 connected to the toilet area 25. The filter element 3 also has filter holes 33 connecting the toilet area 25 and the litter storage area 26. The size of the filter holes 33 is larger than the size of the pet litter particles but smaller than the size of the pet excrement particles. For example, the size of the filter holes 33 is larger than the size of the pet litter particles but smaller than the size of the pet excrement particles. For example, the diameter of the filter holes 33 is larger than the diameter of the pet litter particles but smaller than the diameter of the pet excrement particles. Therefore, during use, the basin 2 can have three states when rotating: initial state, excrement dumping state, and litter return state. Figure 5A and Figure 6A As shown, when the basin 2 is in its initial state, pet litter can be spread evenly in the toilet area 25. Simultaneously, the toilet area 25 can also collect pet excrement or waste. However, when the basin 2 is in the waste-discharging state, such as... Figure 5B and Figure 7A As shown, the basin 2 can be rotated forward to the excrement dumping position, tilting the basin opening 21 towards the opening 12, and positioning the toilet area 25 of the basin 2 above the litter storage area 26. At this time, the pet litter in the toilet area 25 can enter the litter storage area 26 through the filter holes 33 distributed on the filter element 3. Simultaneously, the pet's excrement or waste can roll down into the base 1 through the filter element 3. After the excrement or waste has been emptied, as... Figure 5C and Figure 8AAs shown, the basin 2 can be rotated in the reverse direction to the sand return position. At this time, the rim 21 of the basin 2 is tilted relative to the opening 12 of the base 1, and the toilet area 25 is located below the sand storage area 26. At this time, the pet sand entering the sand storage area 26 can return to the toilet area 25 through the filter holes 33 on the filter element 3. After the basin 2 completes the sand return action, the basin 2 can be rotated in the forward direction back to the initial position, so that the rim 21 of the basin 2 is parallel to the opening 12 of the base 1.

[0077] Furthermore, in order to prevent the pet from entering the sand storage area 26 of the basin 2 when it is in the initial position, in some embodiments, such as Figure 9 As shown, the filter element 3 includes: a filter screen plate 31 and a sand-removing plate 32. Among them, combined with... Figure 4 and Figures 5A to 5C As shown, the filter plate 31 extends from the bowl opening 21 to the bowl bottom 22. This filter plate 31 divides the space within the cavity 11 into a toilet area 25 and a litter storage area 26. The litter cleaning plate 32 also covers part of the bowl opening 21 of the bowl 2, allowing the litter storage area 26 to be opened or closed. The litter cleaning plate 32 prevents pets from entering the litter storage area 26 of the bowl 2. Meanwhile, if... Figure 5A and Figure 9 As shown, through the filter holes 33 distributed on the filter plate 31, when the basin 2 is rotated forward to the excrement dumping position, the pet litter in the toilet area 25 can enter the litter storage area 26. Furthermore, when the basin 2 is rotated in the reverse direction to the litter return position, the pet litter that has entered the litter storage area 26 can return to the toilet area 25. However, it should be noted that in some embodiments, the litter cleaning plate 32 can be connected to the filter plate 31; of course, the litter cleaning plate 32 and the filter plate 31 can also be two separate plates. And, as a preferred embodiment, in some embodiments, such as... Figure 5A and Figure 9 As shown, the filter plate 31 is recessed inward toward the sand storage area 26, making it a concave arc-shaped plate. This allows pet excrement collected on the filter plate 31 to fall accurately into the base 1. Of course, in other embodiments, the filter plate 31 may also be recessed inward toward the toilet area 25. Furthermore, it should be noted that in these embodiments, the filter element 3 is detachably mounted on the basin 2. Of course, in other embodiments, the filter element 3 may be integrally formed with the basin 2, and the connection relationship between the filter element 3 and the basin 2 is not specifically limited here.

[0078] Additionally, in some embodiments, such as Figure 5A and Figure 9As shown, the basin body 2 has a first bottom 221, a second bottom 222, and a connecting portion 223 connecting the first bottom 221 and the second bottom 222. The vertical distance from the basin opening 21 to the first bottom 221 is greater than the vertical distance from the basin opening 21 to the second bottom 222. Furthermore, the filter plate 31 abuts against the side of the connecting portion 223 connected to the first bottom 221. It is easy to see that through the cooperation of the filter plate 31 and the connecting portion 223, the first bottom 221 can be used as the bottom of the toilet area 25, and the second bottom 222 as the bottom of the litter storage area 26. This creates a certain height difference between the bottoms of the two storage areas, allowing the pet litter to quickly return to the toilet area 25 when the basin body 2 is rotated forward to the excrement dumping position without affecting the entry of pet litter into the litter storage area 26, and when the basin body 2 is rotated backward to the litter return position. However, in other embodiments, such as... Figure 5A As shown, the connecting part 223 is also inclined, meaning that from the side connected to the first bottom 221 to the side connected to the second bottom 222, the connecting part 223 is inclined towards the sand storage area 26. For example, the inclination angle of the connecting part 223 can be 15 degrees to 75 degrees, so that the height of the step formed by the connecting part 223 can account for 10% to 45% of the height of the basin 2. This ensures that there is a slope between the first bottom 221 and the second bottom 222, so that when the basin 2 is rotated forward to the excrement pouring position, the filter plate 31 can guide the pet sand into the sand storage area 26. When the basin 2 is rotated in the reverse direction to the sand return position, it can speed up the return of the pet sand to the toilet area 25. Furthermore, in some other embodiments, such as Figure 9 As shown, the filter element 3 also has a connector 34 that is elastically hinged to the third side wall 233 and the fourth side wall 234 of the basin 2, respectively, so that the filter element 3 can rotate with the connector 34 as the pivot point. Therefore, by rotating the filter element 3, the pet sand in the sand storage area 26 can be manually cleaned. At the same time, since the filter element 3 and the basin 2 are elastically hinged, when the basin 2 rotates, the filter screen 31 of the filter element 3 can firmly abut against the connector 223, so as not to affect the rotation of the basin 2 in the state of excrement dumping and the rotation in the state of sand return.

[0079] Additionally, in other embodiments, such as Figure 16 and Figure 17As shown, the filter screen 31 also includes a frame 311 and a screen body 312. The frame 311 extends from the basin opening 21 to the basin bottom 22. The frame 311 can be connected to the sand-cleaning plate 32 or be a separate component. The screen body 312 is disposed within the frame 311, and a portion of the screen body 312 forms a fan blade 3121 that can rotate towards the toilet area 25. That is, the fan blade 3121 can only rotate towards the toilet area 25 and cannot rotate in the opposite direction. Simultaneously, a portion of the screen body 3121 also forms a sand-returning opening 3122 for being opened or closed by the fan blade 3121. Therefore, in practical applications, users can flip the fan blade 3121 to open or close the sand return opening 3122, allowing users to clean the sand storage area 26 manually and put the pet sand that has entered the sand storage area 26 into the toilet area 25 to ensure the cleanliness of the sand storage area 26.

[0080] In addition, such as Figure 16 and Figure 17 As shown, the side of the fan blade 3121 that is hinged to the frame 311 is parallel to the opening 21 of the basin 2, and the fan blade 3121 is used to rotate relative to the frame 311 when the basin 2 rotates. That is, in some embodiments, the fan blade 3121 can rotate relative to the frame 311 when the basin 2 rotates by means of its own weight and / or the power generated during the fine sand return process. For example, when the basin 2 rotates forward to the excrement dumping position, such as Figure 7A As shown, the rim of basin 2 is tilted towards opening 12. At this time, the fan blade 3121 can directly close the sand return opening 3122 under its own weight, allowing basin 2 to empty pet excrement or waste using the filter screen 31. Pet fine sand can then enter the sand storage area 26 through the filter holes 33 on the filter screen 31. When basin 2 is rotated to the sand return position, as... Figure 8A As shown, the rim 21 of the litter box 2 is inclined to the opening 12 of the base 1 of the pet litter box. At this time, combined with Figure 16 and Figure 17 As shown, the fan blade 3121 can directly open the sand return opening 3122 under its own weight and / or the power during the sand return process, so that the pet fine sand temporarily stored in the sand storage area 26 can enter the toilet area 25 through the sand return opening 3122, thereby facilitating the return of pet fine sand to the basin 2, so that the fine sand can be quickly spread in the toilet area 25 during the sand return process.

[0081] Additionally, it is worth noting that, such as Figure 8A As shown, when basin 2 rotates to the sand return position, combined with Figure 16 and Figure 17As shown, the angle of rotation of the fan blade 3121 relative to the frame 311 is less than 90 degrees. Of course, in some other embodiments, when the basin 2 rotates to the sand return position, the angle of rotation of the fan blade 3121 relative to the frame 311 can also be greater than 90 degrees. In order to control the rotation angle of the fan blade 3211, a corresponding limiting structure can be provided at the hinge part between the fan blade 3211 and the frame 311. The rotation angle of the fan blade 3211 can be controlled by the limiting structure, thereby meeting the sand return requirements of the basin 2 at different rotation angles.

[0082] In addition, in order to enable the basin 2 to rotate within the base 1, in some embodiments, such as Figure 6A , Figure 7A and Figure 8A As shown, the pet litter box also includes a first drive mechanism 4, which is connected to the litter box body 2. This first drive mechanism 4 drives the litter box body 2 to rotate about a preset axis. Furthermore, to enable precise control of the rotation angle of the litter box body 2 when the first drive mechanism 4 drives it to rotate forward or backward, as shown... Figures 6A to 8A As shown, a detection module 5 can be installed inside the cavity 11 of the base 1. Simultaneously, the basin 2 is provided with a first element 61, a second element 62, and a third element 63, respectively, that can be detected by the detection module 5, corresponding to the detection module 5. Furthermore, in conjunction with… Figure 27 As shown, both the first drive mechanism 4 and the detection module 5 are electrically connected to the main control module of the pet litter box. Furthermore, it should be noted that in some embodiments, the detection module 5 is a micro switch, and the first element 61, the second element 62, and the third element 63 are all protrusions disposed on the wall 14 of the litter box 2, with each protrusion disposed on the third side wall 233 or the fourth side wall 234, while the micro switch is disposed on the third side plate 143 or the fourth side plate 144 of the base 1.

[0083] Therefore, when the main control module receives the drive command, it combines... Figure 27 and Figure 7A As shown, the main control module can control the first drive mechanism 4, enabling the first drive mechanism 4 to drive the basin 2 to rotate forward. When the micro switch is triggered by the first element 61, the basin 2 rotates to the excrement pouring position. At this time, the micro switch also sends an electrical signal to the main control module. When the main control module receives the electrical signal sent by the micro switch, it can pause the first drive mechanism 4, allowing the basin 2 to remain in the excrement pouring position. Figure 7A The state shown. Additionally, after the basin 2 has finished emptying excrement or waste, and the pet litter in the toilet area 25 has entered the litter storage area 26, the main control module can control the first drive mechanism 4 to drive the basin 2 to rotate in the opposite direction, combined with... Figure 8AAs shown, when the microswitch is triggered by the second element 62, it indicates that the basin 2 has just rotated to the sand return position. At this time, the microswitch can also send an electrical signal to the main control module. When the main control module receives the electrical signal sent by the microswitch, it can pause the first drive mechanism 4, so that the basin 2 can stay in the sand return position. Figure 8A The state shown. Finally, after the pet litter in the litter storage area 26 of the basin 2 returns to the toilet area 25, the main control module can continue to control the first drive mechanism 4, so that the first drive mechanism 4 can drive the basin 2 to rotate forward again. When the micro switch is triggered by the third element 63, it indicates that the basin 2 has returned to the initial position. Figure 6A As shown, the micro switch will also send an electrical signal to the main control module at this time. When the main control module receives the electrical signal sent by the micro switch, it can turn off the first drive mechanism 4, so that the basin 2 can stay in the initial position.

[0084] Furthermore, it should be noted that the detection module 5 is only described using a micro switch as an example. In other embodiments, the detection module 5 may also use a Hall element. When the detection module 5 uses a Hall element, such as... Figure 6B , Figure 7B and Figure 8B As shown, the detection module 5 contains three Hall elements: a first Hall element 61, a second Hall element 62, and a third Hall element 63. Each of these three Hall elements—the first element 61, the second element 62, and the third element 63—can be a Hall magnetic element. Therefore, when the basin 2 rotates to the excrement-pouring position, as... Figure 7B As shown, the first Hall element 51 can detect the first element 61, enabling the first Hall element 51 to output a first Hall signal to the main control module. Upon receiving the first Hall signal, the main control module can pause the first drive mechanism 4, thus allowing the basin 2 to remain in the excrement or waste dumping position. Secondly, when the basin 2 rotates to the sand return position, as... Figure 8B As shown, the second Hall element 52 can detect the second element 62, enabling the second Hall element 62 to output a second Hall signal to the main control module. Upon receiving the second Hall signal, the main control module can pause the first drive mechanism 4, thus allowing the basin 2 to remain at the sand return position. Finally, when the basin 2 rotates to its initial position, as... Figure 6B As shown, the third Hall element 53 can detect the second element 63, so that the third Hall element 63 can output a third Hall signal to the main control module. When the main control module receives the third Hall signal, it can shut down the first drive mechanism 4, so that the basin 2 can stay in the initial position.

[0085] In addition, in order to enable the first drive mechanism 4 to drive the basin 2 to rotate, combined with Figure 6A , Figure 7A and Figure 8AAs shown, the first drive mechanism 4 includes: a rotating bracket 41 and a drive device 42. Wherein, combined with... Figure 2 As shown, the rotating bracket 41 is disposed within the cavity 11 of the base 1 and connected to the basin 2. Next, as... Figure 6A , Figure 7A and Figure 8A As shown, the driving device 42 is connected to the rotating bracket 41, and the driving device 42 is used to drive the rotating bracket 41 to rotate about a preset axis as the pivot axis. Specifically, in some embodiments, such as Figure 10 As shown, the rotating bracket 41 includes a bottom beam 411, a first support beam 412, and a second support beam 413. The bottom beam 411 is located at the bottom of the basin 2, the first support beam 412 is located at one end of the bottom beam 411 along its length, and the second support beam 413 is located at the other end of the bottom beam 411 along its length. Both the first and second support beams extend perpendicular to the bottom beam 411, thus forming a locking area 414 for engaging the basin 2. Figure 2 and Figure 10 As shown, the ends of the first support beam 412 and the second support beam 413 away from the bottom beam 411 are rotatably connected to the base 1. Specifically, the end of the first support beam 412 away from the bottom beam 411 is rotatably connected to the third side plate 143, while the end of the second support beam 413 away from the bottom beam 411 is rotatably connected to the fourth side plate 144. Additionally, as... Figure 5A As shown, the drive device 42 of the first drive mechanism 4 is also electrically connected to the main control module, so that the drive device 42 can drive the rotating bracket 41 to rotate around a preset axis under the control of the main control module, and the basin 2 can rotate together with the rotating bracket 41 under the rotation of the rotating bracket 41.

[0086] Furthermore, in other embodiments, such as Figure 10 and Figure 11 As shown, the first support beam 412 and the second support beam 413 are detachably connected to the basin body 2. Specifically, as... Figure 9 , Figure 10 and Figure 11 As shown, the basin 2 is provided with a first slide rail 2331 into which the first support beam 412 can be inserted, and a second slide rail 2341 into which the second support beam 413 can be inserted. In practical applications, the first support beam 412 and the second support beam 413 can slide into the first slide rail 2331 and the second slide rail 2341 respectively.

[0087] However, as a preferred embodiment, in other embodiments, such as Figures 18 to 20As shown, the first support beam 412 has a first engaging protrusion 4121 on one side relative to the second support beam 413, and the second support beam 413 has a second engaging protrusion 4131 on one side relative to the first support beam 412. Furthermore, in conjunction with 21, Figure 25 and Figure 26 As shown, the basin wall 23 of the basin body 2 is provided with a first limiting protrusion 2311 that can be engaged by the first engaging protrusion 4121, and a second limiting protrusion 2321 that can be engaged by the second engaging protrusion 4131. By engaging the first engaging protrusion 4121 with the first limiting protrusion 2311, and engaging the second engaging protrusion 4131 with the second limiting protrusion 2321, the basin body 2 can be fixed in the cavity 11 of the base 1.

[0088] Specifically, such as Figure 20 and Figure 24 As shown, the first support beam 412 includes a first support arm 4122 and a first elastic arm 4123. The first support arm 4122 is connected to the bottom beam 411 and extends vertically away from the bottom beam 411. The first support arm 4122 has a first rebound space 41221. Simultaneously, combined with… Figure 22 As shown, the first support arm 4122 has a first locking hole 41222 communicating with the first spring space 41221 on one side relative to the second support beam 413, and the first elastic arm 4123 is disposed in the first spring space 41221. Simultaneously, combined with... Figure 21 and Figure 22 As shown, the first elastic arm 4123 partially forms a first locking protrusion 4121, which protrudes from the first locking hole 41222 and is exposed on one side of the first support arm 4122 relative to the second support beam 413. The first elastic arm 4123 is springback relative to the second support beam 4122. Correspondingly, as Figure 20 and Figure 24 As shown, the second support beam 413 includes: a second support arm 4132 and a second elastic arm 4133, wherein the second support arm 4132 is connected to the bottom beam 411 and extends vertically in a direction away from the bottom beam 411, and the second support arm 4132 has a second spring space 41321, and simultaneously, combined with Figure 23 As shown, the second support arm 4132 has a second locking hole 41322 communicating with the second spring-loaded space 41321 on one side relative to the first support beam 412. Furthermore, the second elastic arm 4133 is disposed in the second spring-loaded space 41321, and simultaneously... Figure 21 and Figure 23As shown, the second elastic arm 4133 has a portion forming a second snap-fit ​​protrusion 4131, which protrudes from the second snap hole 41322 and is exposed on one side of the second support arm 4132 relative to the first support beam 412. The second elastic arm 4133 is springback relative to the second support beam 4132.

[0089] Therefore, when the basin 2 is placed into the cavity 11 of the base 1, as Figure 10 and Figure 24 As shown, the first support beam 412 and the second support beam 413 can slide into the first slide rail 2331 and the second slide rail 2341 of the basin 2, respectively. During this process, the first locking protrusion 4121 on the first support beam 412 and the second locking protrusion 4131 on the second support beam 413 will be compressed by the first limiting protrusion 2311 and the second limiting protrusion 2321 on the basin 2. This allows the first elastic arm 4123 and the second elastic arm 4133 to avoid deflection using the first rebound space 41221 and the second rebound space 41321, respectively. When the first locking protrusion 4121 and the second locking protrusion 4131 pass the first limiting protrusion 2311 and the second limiting protrusion 2321, respectively, they combine... Figure 25 and Figure 26 As shown, the first elastic arm 4123 and the second elastic arm 4133 can rebound by their own elasticity, so that the first locking protrusion 4121 and the second locking protrusion 4131 can be locked with the first limiting protrusion 2311 and the second limiting protrusion 2321 respectively, thereby completing the installation and fixation of the basin 2 in the cavity 11 of the housing 1.

[0090] In addition, it is worth mentioning that, such as Figure 12 , Figure 13 and Figure 14 As shown, the drive unit 42 includes: a transmission assembly 421, a motor drive component 422, a drive gear 423, and a gear set 424. Among them, as... Figure 14 As shown, the transmission assembly 421 has a connecting portion 4211 connected to the first support beam 412 or the second support beam 413, and a drive gear 4212 coaxially connected to the connecting portion 4211. The motor drive unit 422 has a main shaft 4221, and a drive gear 423 is coaxially connected to the main shaft 4221 of the motor drive unit 422. A gear set 424 meshes with both the drive gear 423 and the drive gear 4212. Specifically, as... Figure 14As shown, the gear set 424 includes: a first driven gear 4241 and a second driven gear 4242 coaxially connected to the first driven gear 4241. The first driven gear 4241 meshes with the driving gear 423, while the second driven gear 4242 meshes with the driving gear 4212. Furthermore, the motor drive element 422 is electrically connected to the main control module, enabling the main control module to control the main shaft 4221 of the motor drive element 422 to rotate forward or backward according to received drive commands.

[0091] Furthermore, in order to protect the drive unit 42, such as Figure 14 and Figure 15 As shown, the first drive mechanism 4 further includes a housing 43, which houses the drive device 42, allowing the first drive mechanism to be mounted and fixed on the base 1 via the housing 43. Specifically, in some embodiments, such as... Figure 14 and Figure 15 As shown, the housing 43 includes: a gearbox housing 431 and a motor bracket 432 fastened to the gearbox housing 431. A space (not shown in the figure) is formed between the gearbox housing 431 and the motor bracket 432 to accommodate the drive device 42, so that the drive device 42 can be made into an independent module through the housing 43, thereby facilitating its installation and fixation on the shell wall 14 of the base 1.

[0092] Furthermore, in a preferred embodiment, such as Figure 28 As shown, the filter plate 31 and the sand-cleaning plate 32 can also be independently mounted on the litter box 2. Furthermore, the pet litter box also includes a second drive mechanism 8, which is connected to both the filter plate 31 and the sand-cleaning plate 32 of the filter element 3. Simultaneously, combined with... Figures 35A to 35D As shown, the second drive mechanism 8 is also used to drive the filter plate 31 to flip between the start position and the end position within the basin 2.

[0093] When the basin 2 is flipped to the excrement dumping position, combined with Figure 7A and Figure 35B In the state shown, the second drive mechanism 8 is used to drive the filter plate 31 to flip towards the toilet area 25 closer to the basin 2 according to the received drive command. When the filter plate 31 flips to the end position, the filter plate 31 tilts towards the toilet area 25, so that a slope is formed between the filter plate 31 and the basin opening 21. At this time, pet excrement or waste in the toilet area 25 can be more easily poured out of the basin 2 under the guidance of the slope of the filter plate 31.

[0094] Secondly, when basin 2 is tilted to the excrement-pouring position, such as Figure 35CAs shown, the second drive mechanism 8 is also used to drive the sand-cleaning plate 32 to flip into the sand storage area 26 according to the received drive command, so that the sand-cleaning plate 32 opens the sand storage area 26. Meanwhile, it should be noted that when the basin 2 is flipped to the excrement dumping position, as... Figure 35B and Figure 35C As shown, since the toilet area 25 of the basin 2 can be located above the litter storage area 26, it is convenient to dump excrement or waste, and the pet litter laid in the toilet area 25 can also enter the litter storage area 26 through the filter screen 33 on the filter screen plate 31.

[0095] As can be seen from the above, since the second drive mechanism 8 can also be connected to the filter plate 31 and the sand-cleaning plate 32, and when the basin 2 is flipped to the excrement dumping position, the second drive mechanism 8 can drive the filter plate 31 to flip towards the toilet area 25 according to the received command. When the filter plate 31 is flipped to the final position, the entire filter plate 31 is tilted towards the toilet area 25, so that the filter plate 31 has a certain slope. Therefore, the pet's excrement or waste can slide down the slope of the filter plate 31 more quickly. This further facilitates the dumping of excrement or waste. At the same time, if it is necessary to change the sand in the basin 2, when the basin 2 is flipped to the excrement dumping position, the second drive mechanism 8 can continue to drive the sand cleaning plate 32 to flip according to the received instruction, so that the sand cleaning plate 32 opens the sand storage area 26 of the basin 2. Therefore, while dumping excrement from the basin 2, the fine sand that has entered the sand storage area 26 can also be poured out, thereby realizing the sand replacement of the basin 2. Moreover, during the sand replacement process, there is no need to disassemble the basin 2, which facilitates the user's operation when changing sand.

[0096] Additionally, in some other embodiments, after the basin 2 is flipped to its initial position, such as... Figure 28 and 30 In the state shown, the second drive mechanism 8 is also used to drive the filter plate 31 to flip towards the sand storage area 26 according to the received instruction, and when the filter plate 31 flips to the starting position, the entire filter plate 31 tilts towards the sand storage area 26. It is easy to see that since the basin 2 can also drive the filter plate 31 to flip towards the sand storage area 26 when it flips to the initial position, the filter plate 31 tilts towards the sand storage area 26, that is, the filter plate 31 is tilted towards the sand storage area 26. Therefore, the area of ​​the toilet area 25 can be effectively expanded, making it more convenient for pets to enter the toilet area 25 and facilitating the movement of pets in the toilet area 25. This also facilitates the pet's defecation in the toilet area 32, solving the technical problem of space utilization.

[0097] However, in other embodiments, when the basin 2 is in the initial position, and before the second drive mechanism 8 drives the basin 2 to flip to the excrement dumping position, combined with Figure 28 and Figure 30 As shown, the second drive mechanism 8 is also used to drive the filter plate 31 to flip toward the direction closer to the toilet area 25 according to the received instructions, such as... Figure 35A The state shown allows the filter plate 31 to be flipped to a preset position between the start position and the end position, and when the filter plate 31 is flipped to the preset position, as... Figure 28 As shown, the filter plate 31 can be perpendicular to the opening 21 of the basin 2. It is easy to see that before the basin 2 is tilted to the excrement dumping position, by tilting the filter plate 31 to a preset position perpendicular to the opening 21, the gap between the filter plate 31 and the bottom 22 of the basin 2 can be reduced. This ensures that during the tilting process, pet excrement will not seep into the sand storage area 26 through the gap between the filter plate 31 and the bottom 22, allowing the basin 2 to empty as much excrement or waste as possible, thus ensuring the cleanliness of the basin 2.

[0098] Furthermore, in order for the driving component 1 to drive the filter plate 31 and the sand cleaning plate 32 to rotate, such as Figure 28 and Figure 33 As shown, the second driving mechanism 8 includes a transmission assembly 81 and a driving element 82. Both the transmission assembly 81 and the driving element 82 are mounted on the basin 2. The transmission assembly 81 is connected to the filter screen plate 31 and the sand-cleaning plate 32, respectively. The driving element 82 is connected to the transmission assembly 81. The driving element 82 is used to drive the filter screen plate 31 to rotate within the basin 2 via the transmission assembly 81. Simultaneously, the driving element 82 is also used to drive the sand-cleaning plate 32 to rotate via the transmission assembly 81.

[0099] Specifically, in this embodiment, as Figure 28 , Figure 31 and Figure 32 As shown, the driving element 82 is a motor drive, and the transmission assembly 81 includes: a first coupling 811, a first driven gear 812, a second coupling 813, a second driven gear 814, and a driving gear 815. Among these, [the following is a description of the process, not a direct translation]... Figure 33 As shown, the first coupling 811 is connected to the filter plate 31, and simultaneously, as Figure 31 and Figure 32 As shown, the first driven gear 812 is coaxially connected to the first coupling 811. Secondly, in combination... Figure 33 As shown, the second coupling 813 is connected to the sand-cleaning plate 32, and simultaneously, as Figure 31 and Figure 32 As shown, the second driven gear 814 is also coaxially connected to the second coupling 813. Finally, as... Figure 32 As shown, the driving gear 815 is coaxially connected to the main shaft 821 of the motor drive unit. Simultaneously, the driving gear 815 also meshes with the first driven gear 812 and the second driven gear 814. Therefore, when the motor drive unit drives the driving gear 815 to rotate via the main shaft 821, the driving gear 815, relying on its meshing with the first driven gear 812 and the second driven gear 814, drives the first driven gear 812 and the second driven gear 814 to rotate respectively. Ultimately, the first driven gear 812 drives the filter plate 31 to rotate via the first coupling 811, while the second driven gear 814 drives the sand cleaning plate 32 to rotate via the second coupling 813.

[0100] Furthermore, it should be noted that in some embodiments, such as Figure 31 and Figure 33 As shown, the first coupling 811 includes: a first connecting member 8111 connected to the filter plate 31, and a connecting shaft 8112 coaxially connected to the first driven gear 812 and the first connecting member 8111. Meanwhile, as... Figure 31 and Figure 33 As shown, the second coupling 813 includes: a second connecting member 8131 connected to the sand-cleaning plate 32, and a connecting sleeve 8132 coaxially connected to the second driven gear 814 and the second connecting member 8131. Furthermore, combined with... Figure 31 and Figure 32 As shown, the connecting sleeve 8132 and the second driven gear 814 are both sleeved on the connecting shaft 8112. Simultaneously, the connecting sleeve 8132 and the second driven gear 814 are rotatable relative to each other with respect to the connecting shaft 8112. Therefore, when the connecting shaft 8112 is driven by the first driven gear 812, it can drive the filter plate 31 to rotate via the first connecting member 8111. When the filter plate 31 rotates, since the connecting sleeve 8132 and the second driven gear 814 are both sleeved on the connecting shaft 8112 and are rotatable relative to each other with respect to the connecting shaft 8112, the connecting sleeve 8132 and the second driven gear 814 will not rotate with the rotation of the first coupling 811, and will not interfere with the rotation of the filter plate 31. Conversely, when the sand-cleaning plate 32 rotates under the drive of the connecting sleeve 8132, combined with... Figure 31 and Figure 32 As shown, since both the connecting sleeve 8132 and the second driven gear 814 are sleeved on the connecting shaft 8112 and can rotate relative to each other with the connecting shaft 8112, the first driven gear 812 will not rotate with the rotation of the second coupling 813, and at the same time, it will not interfere with the flipping of the sand cleaning plate 32.

[0101] Additionally, it is worth noting that, in order to ensure that when the filter screen plate 31 is flipped to the stop position, the second drive mechanism 8 can continue to drive the sand cleaning plate 32 to flip towards the sand storage area 26 according to the command, in this embodiment, as follows: Figure 32 and Figure 34 As shown, the driving gear 815 includes: a first gear ring 8151 and a second gear ring 8152 coaxially fixed to the first gear ring 8151, and both the first gear ring 8151 and the second gear ring 8152 are coaxially connected to the main shaft 821 of the motor drive component. Wherein, as... Figure 32 and Figure 34 As shown, the first gear ring 8151 includes: a first tooth row 81511 meshing with the first driven gear 812, and a first convex arc surface 81512 that slips off from the first driven gear 812. The second gear ring 8152 includes: a second tooth row 81521 meshing with the second driven gear 814, and a second convex arc surface 81522 that slips off from the second driven gear 814. Furthermore, as... Figure 32 As shown, around the axis of the main shaft 821 of the motor drive component, there is a preset angle difference between the first convex arc surface 81512 and the second convex arc surface 81522. This angle difference allows the filter plate 31 to rotate from the starting position to the ending position. At this time, the first gear ring 8151 of the drive gear 815 can mesh with the first driven gear 812 through the first tooth row 81511, while the second gear ring 8152 of the drive gear 815 can slip with the second driven gear 814 through the second convex arc surface 81522. This ensures that the sand-cleaning plate 32 will not rotate under the driving force of the second coupling 813. Conversely, when the filter plate 31 reaches the ending position, as... Figure 32 As shown, the first gear ring 8151 of the driving gear 815 can slip with the first driven gear 812 through the first convex arc surface 81512, so as to ensure that the filter plate 31 can stay in the end position and the filter plate 31 will not be rotated by the driving force of the first coupling 811. At this time, the second gear ring 8152 of the driving gear 815 can mesh with the second driven gear 814 through the second tooth row 81521, so that the sand cleaning plate 32 can be flipped into the sand storage area 26 by the driving force of the connecting sleeve 8132, thereby opening the sand storage area 26 and pouring out the sand stored in the sand storage area 26 to realize sand replacement.

[0102] Furthermore, it should be noted that during the process of the filter plate 31 flipping from the starting position to the ending position, in order to allow the first driven gear 812 to slip against the first convex arc surface 81512 of the first gear ring 8151, and simultaneously, when the filter plate 31 flips to the ending position, in order to allow the second driven gear 814 to slip against the second convex arc surface 81522 of the second gear ring 8152, in some embodiments, such as... Figure 32 and Figure 34As shown, the tip of at least one tooth 1121 of the first driven gear 812 is a first concave arc surface 8122 that can slip against the first convex arc surface 81512 of the first gear ring 8151. Similarly, the tip of at least one tooth 8141 of the second driven gear 814 is a second concave arc surface 8142 that can slip against the second convex arc surface 81522. It is easy to see that when the filter plate 31 flips from the starting position to the ending position, the second concave arc surface 8142 of the second driven gear 814 and the second convex arc surface 81522 of the second gear ring 8152 can make the second driven gear 814 slip with the driving gear 815. When the filter plate 31 flips to the ending position, the first concave arc surface 8122 of the first driven gear 812 and the first convex arc surface 81512 of the first gear ring 8151 can make the first driven gear 812 slip with the driving gear 815.

[0103] Furthermore, it should be noted that the transmission assembly 81 is only described with the example of including: a first coupling 811, a first driven gear 812, a second coupling 813, a second driven gear 814, and a driving gear 815. In other embodiments, the second drive mechanism 8 may also include two independent motor drive assemblies, and the two motor drive assemblies can be connected to the filter plate 31 and the sand cleaning plate 32 respectively. In this way, the second drive mechanism 8 can also drive the filter plate 31 and the sand cleaning plate 32 to rotate respectively. In this embodiment, the structure of the second drive mechanism 8 is not specifically limited.

[0104] Furthermore, it is worth noting that the above-mentioned sand cleaning plate 32 is only described in the example of the second drive mechanism 8 driving the sand cleaning plate 32 to rotate inward into the sand body temporary storage area 26 during the process of opening the sand body temporary storage area 26. In other embodiments, the second drive mechanism 8 can also open the sand body temporary storage area 26 by driving the sand cleaning plate 32 to rotate outward. In this embodiment, the rotation direction of the sand cleaning plate 32 when opening the sand body temporary storage area 26 is not specifically limited.

[0105] In addition, in order to provide power and control to the second drive mechanism 8, the second drive mechanism 8 also needs to be electrically connected to the main control module. Furthermore, to ensure that the main control module can be electrically connected to the second drive mechanism 8 without affecting the rotation of the basin 2, the following steps must be taken. Figure 33 As shown, an electrical connector 9 is also provided on the basin body 2, and the electrical connector 9 is also electrically connected to the second drive mechanism 8. Furthermore, combined with... Figure 29 As shown, the electrical connector 9 is used to connect the basin 2 to the rotating bracket 41, and then to the electrical connector 20 disposed on the rotating bracket 41, thereby enabling electrical conductivity between the electrical connector 9 and the electrical connector 20. Secondly, as... Figure 33 As shown, the direction from the rim 21 to the bottom 22 of the basin 2 is the height direction of the basin 2, and the skirt 24 is provided with mounting holes 27 along the height direction of the basin 2, while the electrical connector 9 is provided in the mounting holes 27 of the skirt 24.

[0106] Furthermore, it is worth noting that in some embodiments, such as Figure 33 As shown, the skirt 24 has a top side 241 and a bottom side 242 opposite to the top side 241 along the height direction of the basin 2. Meanwhile, to facilitate the installation of the electrical connector 9 in the mounting hole 27, as... Figure 33 As shown, the top side 241 of the skirt 24 is also provided with a mounting groove 28 communicating with the mounting hole 27, and a top cover 29 for closing the mounting groove 28. The top cover 29 is detachably connected to the skirt 24; for example, the top cover 29 and the skirt 24 can be connected by a snap-fit ​​or by locking with bolts or other locking devices. It is easy to see that by closing the mounting groove 28 with the top cover 29, the electrical connector 9 installed in the mounting hole 27 can be effectively protected.

[0107] Furthermore, it is worth noting that in some embodiments, the combination Figure 29 As shown, the electrical connector 9 can be either a male or female connector. When the electrical connector 9 is a male connector, the electrical connector 20 is a female connector. Conversely, when the electrical connector 9 is a female connector, the electrical connector 20 is a male connector. This arrangement facilitates the connection between the electrical connector 9 and the electrical connector 20 when connecting the basin 2 to the rotating bracket 41, thereby ensuring electrical continuity between them.

[0108] Additionally, it is worth mentioning that in some embodiments, the combination Figure 36 As shown, the first support beam 412 of the rotating bracket 41 can be used as the active rotating beam, while the second support beam 413 can be used as the driven rotating beam. In combination with... Figure 33 As shown, the first support beam 412 can be connected to the connection portion 4211 of the drive device 42, while the second support beam 413 is provided with an electrical connector 20. For example, in some embodiments, such as Figure 29 and Figure 33 As shown, the electrical connector 20 can be disposed at the end of the second support beam 413 away from the bottom beam 411. Of course, in other embodiments, the electrical connector 20 can also be disposed at other parts of the second support beam 413 or at other positions of the rotating bracket 41. However, in this embodiment, the position of the electrical connector 20 on the rotating bracket 41 is not specifically limited.

[0109] Additionally, it is worth mentioning that in some other embodiments, such as Figure 29 and Figure 33As shown, a wiring channel 4131 is provided inside the second support beam 413, and the wiring channel 4131 extends from one end of the second support beam 413 away from the bottom beam 62 to the other end. At the same time, the wiring channel 4131 is used to guide the power supply harness connected to the electrical connector 20 to the outside of the second support beam 413, so as to facilitate the electrical connection between the main control module and the second drive mechanism 8.

[0110] Furthermore, it is worth noting that in this embodiment, such as Figure 28 and Figure 33 As shown, a driven shaft 16 is rotatably provided on the shell wall 14 of the base 1, and the second support beam 413 is also connected to the driven shaft 16, and in combination with... Figure 36 As shown, the driven shaft 16 and the connecting part 4211 of the drive device 42 are coaxially arranged along a preset axis. At the same time, the connecting part 4211 and the driven shaft 16 can be rotated relative to the base 1 with the preset axis as the pivot axis. Therefore, when the basin 2 is connected to the first support beam 412 and the second support beam 413 of the rotating bracket 41, the rotating bracket 41 can rotate in the cavity 11 of the base 1 under the drive of the connecting part 4211, thereby causing the basin 2 to flip in the cavity 11.

[0111] Furthermore, in order to smoothly guide the power supply harness from the wiring channel 4131 to the outside of the second support beam 413, so as to ensure that the power supply harness can normally supply power and transmit electrical signals to the second drive mechanism 8, such as... Figure 33 As shown, the driven shaft 16 is provided with a shaft hole 161 communicating with the wiring channel 4131 along the preset axis direction. The power supply cable harness connected to the electrical connector 20 can pass through the wiring channel 4131 to the outside of the second support beam 413 through the shaft hole 161. Therefore, when the rotating bracket 41 drives the basin 2 to flip, the power supply cable harness can be prevented from being twisted by the driving force of the rotating bracket 41 during rotation by means of the shaft hole 161, thereby ensuring the stability of the second drive mechanism 8 when driving the filter plate 31 and the sand cleaning plate 32 to flip.

[0112] Additionally, in other embodiments, such as Figure 1 and Figure 3 As shown, the pet litter box includes a waste collector 7, which is detachably installed inside the cavity 11 and located at the bottom 13 of the base 1. The waste collector 7 is used to collect excrement or waste poured out of the litter box 2 when the litter box 2 is rotated to a first preset angle. Because the waste collector 7 is detachably installed inside the cavity 11 of the base 1, it facilitates both the collection of pet excrement or waste and the cleaning up of pet excrement or waste by the user.

[0113] Furthermore, in order to enable the waste collector 7 to collect pet excrement or waste, combined with Figure 3 and Figure 38 As shown, the waste collector 7 has a collection trough 71 on the side facing the opening 12 of the base 1, which facilitates the collection of pet excrement or waste. Furthermore, as a preferred embodiment, in some embodiments, such as... Figure 7A and Figure 8A As shown, when the basin 2 rotates, a portion of it may enter the collection trough 71. Therefore, a second clearance gap is formed between each wall 711 of the collection trough 71 and the basin wall 23 of the basin 2 to allow the basin 2 to rotate. The second clearance gap can prevent the waste collector 7 from interfering with the rotation of the basin 2.

[0114] In addition, such as Figure 3 As shown, the base 1 is also provided with an outlet 15 communicating with the cavity 11. The outlet 15 is used for the waste collector 7 to slide into or out of the cavity 11. The outlet 15 is located on the shell wall 14 of the base 1, that is, the outlet 15 can be located on the first side plate 141, the second side plate 142, the third side plate 143, or the fourth side plate 144 of the shell wall 14. This allows the user to remove and install the waste collector 7 through the outlet 15, thereby facilitating the user's cleaning of pet excrement or waste.

[0115] Furthermore, in other embodiments, the pet litter box also includes: an odor control device, and, combined with Figure 37 and Figure 38 As shown, the deodorizing device includes a liquid storage container 30 and a pressing mechanism 10. The liquid storage container 30 stores the deodorizing medium and has a pressable nozzle 301. The pressing mechanism 10 receives an electrical signal and presses the nozzle 301 according to the received signal, causing the nozzle 301 to draw the deodorizing medium from the liquid storage container 30 and spray the drawn deodorizing medium outwards.

[0116] Specifically, in some embodiments, such as Figure 37 and Figure 39 As shown, the pressing mechanism 10 includes: a trigger 101 and a driving device 102. Wherein, as... Figure 37 As shown, the trigger 101 is disposed opposite to the pressable nozzle 301 of the liquid storage container 30, and in some embodiments, the trigger 101 may be a pressure rod. In addition, the drive device 102 may drive the trigger 101 to move relative to the nozzle 301 according to the received electrical signal, so that the trigger 101 presses the nozzle 301.

[0117] In addition, combined Figure 39As shown, the drive device 102 includes: a motor 1021, a crank 1022 rotatably connected to the trigger 101, and a transmission assembly 1023 connected to the main shaft of the motor 1021 and the crank 1022 respectively. The motor 1021 drives the crank 1022 to rotate via the transmission assembly 1023, and the crank 1022, when rotating, drives the trigger 101 to move relative to the nozzle 301, thereby enabling the nozzle 301 to extract and spray the deodorizing medium from the liquid storage container 30.

[0118] Furthermore, it is worth mentioning that in some embodiments, such as Figure 37 , Figure 39 and Figure 40 As shown, the transmission assembly 1023 includes: a drive gear 10231, a driving gear 10232, and a gear set 10233. The drive gear 10231 is connected to the main shaft of the motor 1021, the driving gear 10232 is eccentrically connected to the crank 1022, and the gear set 10233 meshes with both the drive gear 10231 and the driving gear 10232. Furthermore, as... Figure 39 and Figure 40 As shown, the gear assembly 10233 includes: a first driven gear 102331 meshing with the driving gear 10231; a second driven gear 102332 coaxially connected to the first driven gear 102331; a third driven gear 102333 meshing with the second driven gear 102332; and a fourth driven gear 102334 coaxially connected to the third driven gear, which also meshes with the driving gear 10232. It is clear that the driving force of the motor shaft can be transmitted to the differentiating member 1022 through the meshing of multiple driven gears, allowing the crank member 1022 to drive the trigger member 101 to move relative to the nozzle 301, thus completing the extraction and spraying of the deodorizing medium. Furthermore, it should be noted that in some embodiments, the sizes of the first driven gear 102331, the second driven gear 102332, the third driven gear 102333, and the fourth driven gear 102334 can be adjusted according to the actual transmission ratio requirements, but are not specifically limited in this embodiment.

[0119] Furthermore, in some embodiments, such as Figure 39 and Figure 40 As shown, the crank component 1022 includes: an eccentric wheel 10221 eccentrically connected to the drive gear 10232, and a crank 10222 disposed on the eccentric wheel 10221. The crank 10222 can also be connected to the trigger member 101. Thus, when the drive gear 10232 rotates, the eccentric connection between the eccentric wheel 10221 and the drive gear 10232 enables the crank 10222 to drive the trigger member 101 to move relative to the nozzle 301, thereby realizing the extraction and spraying of the deodorizing medium in the liquid storage container 30 by the nozzle 301.

[0120] Additionally, in other embodiments, such as Figure 37 , Figure 39 and Figure 40 As shown, the pressing mechanism 10 includes a limit switch 103. The limit switch 103 has a trigger end that abuts against the eccentric wheel 10221 of the crank member 1022. This trigger end is used to trigger the limit switch 103 when the eccentric wheel 10221 of the crank member 1022 rotates to a preset angle, allowing the limit switch 103 to output a detection signal. For example, in conjunction with... Figure 41 As shown, both the limit switch 103 and the motor 1021 of the drive device 102 can be electrically connected to the main control module. The main control module can turn on the motor 1021 according to the received deodorization command, so that the drive device 102 can drive the trigger 101 to move relative to the nozzle 301, thereby enabling the nozzle 301 to extract and spray the deodorizing medium. Furthermore, when the drive device 102 is driving the trigger 101, the eccentric wheel 10221 will trigger the limit switch 103. Therefore, once the limit switch 103 is triggered, it will output a detection signal to the main control module, allowing the main control module to shut down the motor 1021. Of course, in some other embodiments, the number of times the main control module receives the detection signal output by the limit switch 103 can be preset. That is, when the motor 1021 of the drive device 102 is turned on, the main control module will only shut down the motor 102 when the number of detection signals received from the limit switch 103 reaches the preset number. This allows the trigger 101 to press the nozzle 301 multiple times after the motor 1021 of the drive device 102 is turned on, thereby achieving a better deodorization effect.

[0121] Furthermore, in order to send deodorization commands to the main control module, in some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the litter box also includes a button module 100, which is mounted on the base 1. Additionally, it is combined with... Figure 41As shown, the button module 100 is also electrically connected to the main control module, and is used to send a deodorization command to the main control module. Simultaneously, the button module 100 can also serve as an execution component for sending drive commands to the main control module, enabling the main control module to open the first drive mechanism 4 and / or the second drive mechanism 8 according to the received drive commands. For example, pressing the button module 100 once within a preset time period causes the button module 100 to send a drive command to the main control module, while pressing the button module 100 twice consecutively within the preset time period causes the button module 100 to send a deodorization command to the main control module. The main control module can determine whether the button module 100 is sending a deodorization command or a drive command based on the number of electrical signals received from the button module 100 within the preset time period. Of course, in other embodiments, the button module 100 can also use other triggering methods to send deodorization and drive commands.

[0122] Example 2

[0123] Some embodiments of the present invention also relate to a method for controlling a pet litter box, which is applied to the pet litter box as described in Embodiment 1, and, as Figure 42 As shown, it includes the following steps:

[0124] According to the received drive command, the litter box body 2 is driven to rotate around a preset axis. The rim 21 of the litter box body 2 is designed to intersect with the opening 12 of the base 1 on which the litter box body 2 is placed when the litter box body 2 rotates, and the angle formed by the intersection of the rim 21 and the opening 12 changes as the litter box body 2 rotates.

[0125] As can be seen from the above, since the base 1 has an opening 12 and the basin 2 has a rim 21, and the basin 2 can rotate with a preset axis as the pivot axis, and when the basin 2 rotates with the preset axis as the pivot axis, the rim 21 of the basin 2 can intersect with the opening 12 of the base 1, and the angle formed by the rim 21 and the opening 12 can change with the rotation of the basin 2, so that the rim 21 of the basin 2 and the opening 12 of the base 1 of the pet litter box in this embodiment have a large size, while also laying the foundation for the separation of pet fine sand and pet excrement or waste.

[0126] Specifically, the step of driving the basin 2 to rotate around a preset axis according to the received driving command includes:

[0127] Step 4210: According to the received driving command, drive the basin 2 to rotate in the positive direction around the preset axis as the pivot axis.

[0128] Step 4220: When the litter box 2 rotates forward to the waste dumping position, the litter box 2 stops rotating, allowing the waste or debris in the toilet area 25 to flow through the filter element 3 into the waste collector 7 of the pet litter box. Simultaneously, the fine pet litter laid in the toilet area passes through the filter holes 33 of the filter element 3 into the litter storage area 26. When the litter box 2 rotates to the waste dumping position, the bowl opening 21 is tilted relative to the opening 12, and the toilet area 25 is located above the litter storage area 26.

[0129] Step 4230: When the basin 2 remains in the excrement dumping position for a period of time that reaches the first preset time, the basin 2 is driven to rotate in the opposite direction around the preset axis.

[0130] Step 4240: When the basin 2 rotates in the reverse direction to the litter return position, control the basin 2 to stop rotating, allowing the pet sand that has entered the litter storage area 26 to return to the toilet area 25 through the filter holes 33 on the filter element 3. Specifically, when the basin 2 rotates to the litter return position, combined with... Figure 5C and Figure 35D As shown, the basin opening 21 is inclined to the opening 12, and the sand storage area 26 is located above the toilet area 25.

[0131] Step 4250: When the time that the basin 2 stays at the sand return position reaches the second preset time, continue to drive the basin 2 to rotate in the positive direction around the preset axis as the pivot axis.

[0132] Step 4260: When the basin 2 rotates to the initial position, control the basin 2 to stop rotating, completing the dumping of excrement or waste and sand return operation. When the basin 2 rotates to the initial position, the basin opening 21 is parallel to the opening 12.

[0133] Additionally, in some other embodiments, combined with Figure 4 and Figure 5A As shown, the filter plate 31 extends from the bowl opening 21 to the bowl bottom 22. This filter plate 31 divides the space within the cavity 11 into a toilet area 25 and a litter storage area 26. The litter cleaning plate 32 also covers part of the bowl opening 21 to allow for the opening or closing of the litter storage area 26. The litter cleaning plate 32 prevents pets from entering the litter storage area 26 of the bowl 2. Therefore, after the bowl is rotated forward to the excrement dumping position (i.e., after step 4220) and before the bowl 2 is driven to rotate in the opposite direction around a preset axis (i.e., before step 4230), as... Figure 43 As shown, the control method further includes the following steps:

[0134] Step 4221: According to the received driving command, drive the filter plate 31 to flip towards the toilet area 25.

[0135] Step 4222: When the filter plate 31 is flipped to the end position, control the filter plate 31 to stop flipping, so that the filter plate 31 is tilted towards the toilet area 25. By flipping the filter plate 31, a slope is formed between the filter plate 31 and the bowl opening 21, which can speed up the dumping rate of pet excrement or waste.

[0136] Step 4223: Based on the received drive command, determine whether sand cleaning of the sand storage area 26 is required. If the determination result is no, continue to step 4230.

[0137] Step 4224: If the determination result is yes, then drive the sand cleaning plate 32 to rotate towards or outward from the sand body temporary storage area 26, so that the sand cleaning plate 32 opens the sand body temporary storage area 26, i.e. Figure 35C As shown in the diagram, when the sand storage area 26 of the sand-cleaning plate 32 has been open for a third preset time, step 4230 continues to be executed. That is, when the time the basin 2 remains in the excrement dumping position has reached a first preset time, the basin 2 continues to be driven to rotate in the opposite direction around the preset axis. The third preset time is less than the first preset time.

[0138] Furthermore, it should be noted that in determining whether sand cleaning of the sand storage area 26 is necessary based on the received drive command, step 4223 specifically includes:

[0139] If the duration of the received driver instruction is greater than or equal to the preset duration, the result is yes.

[0140] If the duration of the received driver instruction is less than the preset duration, the result is negative.

[0141] For example, combining Figures 1 to 3 As shown, a button module 100 can be installed on the base 1. The button module 100 is used to send corresponding drive commands to the main control module of the litter box. The main control module can determine whether the litter storage area 26 needs to be cleaned based on the duration of the received drive command. For example, when the button module 100 is pressed for a long time, the drive command sent to the main control module is a drive command that requires litter cleaning, so that when the litter box 2 is flipped to the excrement dumping position, the litter storage area 26 of the litter box 2 still needs to be cleaned. When the button module 100 is pressed for a short time, the drive command sent to the main control module is a drive command that does not require litter cleaning, so that when the litter box 2 is flipped to the excrement dumping position, the litter storage area 26 of the litter box 2 does not need to be cleaned.

[0142] Additionally, in other embodiments, after the basin 2 is flipped to the initial position, i.e. after step 4260, such as... Figure 43 As shown, the control method further includes the following steps:

[0143] Step 4270: Drive the filter plate 31 to flip towards the sand storage area 26 to the starting position, so that the entire filter plate 31 tilts towards the sand storage area 26. By flipping the filter plate 31 to the starting position, the area of ​​the toilet area 25 can be effectively expanded, making it more convenient for pets to enter the toilet area 25 and facilitating their movement within the toilet area 25. This also facilitates pets defecating in the toilet area 32, solving the technical problem of space utilization.

[0144] Furthermore, it is worth mentioning that after receiving the drive command, and before the drive basin 2 rotates in the positive direction around the preset axis, i.e. before step 4210, such as Figure 43 As shown, the control method further includes the following steps:

[0145] Step 4209: According to the received driving command, drive the filter plate 31 to flip towards the toilet area 25, so that the filter plate 31 stops at a preset position between the start position and the end position. When the filter plate 31 is flipped to the preset position, the filter plate 31 is perpendicular to the opening 21 of the basin body 2.

[0146] It is easy to see that by setting the filter plate 31 perpendicular to the direction of the basin 21 before controlling the basin 2 to flip towards the toilet area 25, the gap between the filter plate 31 and the bottom 22 of the basin 2 can be effectively reduced. This ensures that when the basin 2 is flipped to the excrement dumping position, the pet's excrement or waste will not seep into the litter storage area 26 through the gap between the filter plate 31 and the bottom 22. This allows the basin 2 to empty the excrement or waste as cleanly as possible during the process of dumping the excrement or waste, ensuring the cleanliness of the basin 2.

[0147] In addition, in some other embodiments, the sand-cleaning plate 32 can also be independently flipped on the basin 2, that is, the control method further includes the following steps:

[0148] Based on the received drive command, determine whether it is necessary to clean the sand in the sand storage area 26.

[0149] If the determination result is yes, then drive the sand cleaning plate 32 to flip inward or outward towards the sand body temporary storage area 26, so that the sand cleaning plate 32 opens the sand body temporary storage area 26.

[0150] Furthermore, it should be noted that the method for determining whether sand cleaning of the sand storage area 26 is necessary based on the received drive command can be the same as step 4223, specifically including:

[0151] If the duration of the received driver instruction is greater than or equal to the preset duration, the result is yes.

[0152] If the duration of the received driver instruction is less than the preset duration, the result is negative.

[0153] As can be seen from the above, this embodiment is an embodiment of the pet litter box control method corresponding to the first embodiment, and this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and will not be repeated here to avoid repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.

[0154] Those skilled in the art will understand that the above embodiments are specific embodiments for implementing this application, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of this application.

Simultaneously, fine pet litter laid in the toilet area passes through the filter holes of the filter into the litter storage area. When the litter box is rotated forward to the waste-pouring position, the bowl opening is tilted relative to the opening, and the toilet area is located above the litter storage area. When the basin remains in the excrement dumping position for a period of time that reaches the first preset time, the basin continues to be driven to rotate in the opposite direction around the preset axis as the pivot axis. When the basin is rotated in the reverse direction to the sand return position, the basin is controlled to stop rotating, so that the pet sand that has entered the sand storage area returns to the toilet area through the filter holes on the filter element; wherein, when the basin is rotated in the reverse direction to the sand return position, the basin opening is tilted to the opening, and the sand storage area is located above the toilet area. When the basin remains at the sand return position for a period of time that reaches the second preset duration, the basin continues to be driven to rotate in the positive direction around the preset axis as the pivot axis. When the basin rotates to the initial position, the basin is controlled to stop rotating, completing the dumping of excrement or waste and sand return operation; wherein, when the basin rotates to the initial position, the basin opening is parallel to the opening.

20. The method for controlling a pet litter box according to claim 19, characterized in that, The filter element includes a filter screen and a sand removal plate; wherein, the filter screen divides the space inside the basin into the toilet area and the sand storage area; the sand removal plate covers part of the basin opening and is used to open or close the sand storage area. After the basin is rotated forward to the excrement-pouring position, and before driving the basin to rotate in the reverse direction around a preset axis, the control method further includes the following steps: According to the received driving command, the filter plate is driven to flip towards the toilet area; When the filter plate is flipped to the end position, the filter plate is controlled to stop flipping, so that the entire filter plate is tilted towards the toilet area; Based on the received driving command, determine whether it is necessary to clean the sand in the sand storage area; If the determination result is yes, then drive the sand cleaning plate to flip towards the sand body temporary storage area or towards the sand body temporary storage area, so that the sand cleaning plate opens the sand body temporary storage area.

21. The pet litter box control method according to claim 20, wherein after the litter box is flipped to the initial position, the control method further includes the following steps: Drive the filter screen plate to flip to the starting position in the direction of the sand storage area, so that the filter screen plate as a whole tilts in the direction of the sand storage area.

22. The method for controlling a pet litter box according to claim 21, characterized in that, Upon receiving the drive command, and before driving the basin to rotate positively around a preset axis as the pivot axis, the control method further includes the following steps: According to the received driving command, the filter plate is driven to flip towards the toilet area, so that the filter plate stops at a preset position between the start position and the end position; wherein, when the filter plate is flipped to the preset position, the filter plate is perpendicular to the opening of the basin.
