Description

Technical Field

[0001] The present invention relates to the technical field of pet toilets, and particularly to pet toilets.

Background Art

[0002] Most of the current pet toilets are common containers such as litter boxes. Cat litter is placed in the litter box and provided for pets to enter and defecate. However, after defecation, the owner needs to clean the excrement, which not only takes time and effort, but the smell is also unbearable for the owner. Therefore, there is an urgent need in the market to provide intelligent litter boxes that can automatically clean feces, thereby improving the user experience.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In order to overcome the drawbacks of the prior art, the technical means adopted by the present invention to solve its technical problems are as follows.

Means for Solving the Problems

[0004] The present invention provides a pet toilet. The pet toilet includes a drum, a base, a sieve assembly, and a drive device. The drum has a first opening and a first accommodation space. The first opening communicates with the first accommodation space, and the first accommodation space is used to accommodate the excrement of the pet and the pet sand. The drum is supported by the base, and the base has a second opening. The sieve assembly is connected to the drum. The sieve assembly forms a second accommodation space together with the inner wall of the drum. The second accommodation space is adjacent to the first accommodation space, and the sieve assembly is used to sieve the pet sand and the excrement. The drive mechanism is used to rotate the drum on the base, and as the first opening rotates with the drum from its initial position to the excretion position, the pet litter can pass through the sieve assembly and enter the second containment space, and the excrement is kept outside the second containment space, and as the first opening rotates with the drum and aligns with the second opening, the first opening communicates with the second opening, and the excrement can be discharged through the first and second openings by gravity. As the first opening rotates with the drum from the excretion position to the initial position, the first and second openings become misaligned, the drum covers the second opening, and the pet litter in the second containment space can pass through the sieving assembly and return to the first containment space by its own gravity. The pet toilet further includes an internal infrared detection device and a control board mounted on the base. The internal infrared detection device is electrically connected to the control board and is used to detect whether or not a pet has entered the second opening, thereby preventing the pet from getting trapped. The internal infrared detection device is positioned above the second opening. When the first opening rotates with the drum from the defecation position to the initial position, and the internal infrared detection device detects that a pet has entered the second opening, the control board controls the drive mechanism to reverse the rotation of the drum and the first opening to the defecation position. [Effects of the Invention]

[0005] The beneficial effects of this invention are as follows: This invention provides a pet toilet. An internal infrared detection device is installed inside the base, above the second opening, and in conjunction with the control board, the drive unit is controlled, allowing real-time detection of whether a pet has entered the second opening or the feces collection passage during the process of the drum returning from the defecation position to the initial position. If pet entry is detected, the control board immediately controls the drive unit to reverse the rotation of the drum to the defecation position. This avoids the risk of the pet being trapped or crushed while the drum is rotating, effectively improving the safety and reliability of the pet toilet. It is particularly suitable for active and small pets, reducing the possibility of accidents and increasing user confidence in the product and the overall user experience.

Embodiments for Carrying Out the Invention

[0008] Refer to FIGS. 1 to 21. The pet toilet includes a drum 1, a base 2, a sieve assembly 3, and a drive device 4.

[0009] The drum 1 has a first opening 11 and a first accommodation space 12. The first opening 11 communicates with the first accommodation space 12. The first accommodation space 12 is used to accommodate the excrement of the pet and the pet sand.

[0010] The drum 1 is supported by the base 2. The base 2 has a second opening 21.

[0011] The sieve assembly 3 is connected to the drum 1. The sieve assembly 3 forms a second accommodation space 13 together with the inner wall of the drum 1. The second accommodation space 13 is adjacent to the first accommodation space 12. The sieve assembly 3 is used to sieve and separate the pet sand and the excrement.

[0012] The drive unit 4 is used to rotate the drum 1 on the base 2. When the first opening 11 rotates with the drum 1 from its initial position to the excretion position, the pet litter can pass through the sieve assembly 3 and enter the second containment space 13, and the excrement is kept outside the second containment space 13. When the first opening 11 rotates with the drum 1 and aligns with the second opening 21, the first opening 11 communicates with the second opening 21, and the excrement can be discharged through the first opening 11 and the second opening 21 by gravity.

[0013] As the first opening 11 rotates with the drum 1 from the excretion position to the initial position, the first opening 11 and the second opening 21 become misaligned, the drum 1 covers the second opening 21, and the pet litter in the second containment space 13 can pass through the sieve assembly 3 and return to the first containment space 12 by its own gravity.

[0014] With the above configuration, by arranging a sieve assembly 3 inside the drum 1, which surrounds the inner wall and forms a second containment space 13, the first containment space 12 and the second containment space 13 cooperate with each other, achieving automatic separation of pet litter and excrement during the rotation process of the drum 1. When the drum 1 rotates from the initial position to the excrement position, the pet litter can pass through the sieve assembly 3 and enter the second containment space 13, while the excrement is blocked by the sieve assembly 3. After the first opening 11 is aligned with the second opening 21 of the base 2, the excrement is smoothly discharged by gravity without requiring human intervention. When the drum 1 returns from the excrement position to the initial position, the first opening 11 and the second opening 21 are misaligned, and the drum 1 covers the second opening 21, preventing pet litter from leaking out. At the same time, the pet litter in the second containment space 13 passes through the sieve assembly 3 again and automatically returns to the first containment space 12 by gravity, realizing the recycling of pet litter. According to the above configuration, it is possible to improve the level of automation in cleaning up excrement and reduce the cleaning burden on the user, as well as reduce the waste of pet litter and improve the convenience of use and overall hygienic performance of the pet toilet.

[0015] In this embodiment, the pet toilet further includes a feces collection box 5. The feces collection box 5 is located below the base 2. The feces collection box 5 has a third containment space 51 and a third opening 52. The third opening 52 communicates with the third containment space 51. When the first opening 11 rotates with the drum 1 from its initial position to the excretion position, the pet litter can pass through the sieve assembly 3 and enter the second containment space 13, while the excrement is kept outside the second containment space 13. As the first opening 11 rotates and aligns with and communicates with the second opening 21 and the third opening 52, the excrement falls into the third containment space 51 through the first opening 11, the second opening 21 and the third opening 52 by its own gravity. With the above configuration, in this embodiment, a feces collection box 5 is additionally installed below the base 2, forming an excretion passage in which the third opening 52 of the feces collection box 5, the second opening 21 of the base 2, and the first opening 11 of the drum 1 communicate sequentially at the excretion position. When the drum 1 rotates from the initial position to the excretion position, the pet litter enters the second containment space 13 via the sieve assembly 3 and is effectively separated, and the excrement falls sequentially along the first opening 11, the second opening 21, and the third opening 52 due to the action of gravity and is concentrated in the third containment space 51 of the feces collection box 5, thereby achieving a sealed, centralized containment of excrement, making it easy for the user to remove and clean the feces collection box 5 all at once, and ultimately further improving the cleaning efficiency, hygiene of use, and overall user experience of the pet toilet.

[0016] In this embodiment, the pet toilet further includes a step stool 6. The step stool 6 is connected to a feces collection box 5. The step stool 6 is provided on the side where the first opening 11 is in its initial position. The step stool 6 is provided with a connecting member 61. The feces collection box 5 is provided with a connecting mating member 53. The connecting member 61 and the connecting mating member 53 are detachably connected, thereby detachably connecting the step stool 6 and the feces collection box 5. Specifically, the connecting member 61 includes a locking claw 611 provided on the step stool 6, and the connecting mating member 53 includes a locking groove 531 provided on the feces collection box 5. By engaging the locking claw 611 and the locking groove 531, the step stool 6 and the feces collection box 5 are detachably connected. Alternatively, the connecting member 61 includes a locking groove 531 provided on the step stool 6, and the connecting mating member 53 includes a locking claw 611 provided on the feces collection box 5. By engaging the locking claw 611 with the locking groove 531, the step stool 6 and the feces collection box 5 are detachably connected. With the above configuration, the step stool 6 is detachably attached to the feces collection box 5, and the step stool 6 is positioned so that the first opening 11 faces the initial position. This allows pets to step onto and transition to the pet toilet via the step stool 6, reducing the height difference when entering and exiting, and improving the comfort and safety of the pet when using it. This is especially suitable for small, young, or agile pet cats. At the same time, a detachable connecting structure using the locking claw 611 and locking groove 531 is adopted between the step stool 6 and the feces collection box 5, ensuring the stability and reliability of the connection while making it easy to remove, clean, or replace the step stool 6 on its own.

[0017] In this embodiment, a connecting portion 54 is provided protruding from one end of the feces collection box 5 closest to the step stool 6, and the connecting member 61 is provided on the connecting portion 54. A hollow groove 541 and a first handle hole 542 communicating with the hollow groove 541 are provided at the bottom of the connecting portion 54. Specifically, the connecting portion 54 and the feces collection box 5 are integrally molded. By providing a connecting portion 54 protruding from one end of the feces collection box 5 closest to the step stool 6, and by providing the connecting member 61 of the step stool 6 on the connecting portion 54, the connection between the step stool 6 and the feces collection box 5 is effectively achieved. At the same time, by providing a hollow groove 541 and a first handle hole 542 communicating with the hollow groove 541 at the bottom of the connecting part 54, the amount of material used is reduced while ensuring the structural strength of the connecting part 54, reducing the overall weight. Furthermore, it enables the user to directly lift the feces collection box 5 through the handle hole, allowing for quick removal, emptying, and cleaning of the feces collection box 5. In addition, by making the connecting part 54 and the feces collection box 5 an integrated molded structure, the number of parts and assembly process are reduced, thereby lowering manufacturing costs.

[0018] In this embodiment, the step stool 6 comprises a step plate 62 and a support plate 63 connected to the step plate 62. Multiple anti-slip protrusions 621 are provided on the upper surface of the step plate 62. Multiple first reinforcing ribs 622 are provided on the lower surface of the step plate 62. With the above configuration, the frictional force when a pet steps on it can be effectively increased to prevent slipping. In addition, by providing the first reinforcing ribs 622 on the lower surface of the step plate 62, the overall strength and load support stability of the step stool 6 can be improved, deformation and damage during long-term use can be avoided, and ultimately the safety of the pet toilet as a whole can be improved.

[0019] In this embodiment, the support plate 63 of the step stool 6 is provided with a second handle hole 631, and the upper edge of the second handle hole 631 is arc-shaped. With this configuration, by providing the second handle hole 631 on the support plate 63, it becomes easier for the user to grasp the step stool 6 when removing or moving it, and in turn, improves the convenience of transporting and loading / unloading the step stool 6 and the feces collection box 5 together. Furthermore, the design of the arc-shaped upper edge improves the fit between the handle hole and the palm and fingers, effectively alleviating localized pressure when gripping and avoiding pressure on the hand from corners.

[0020] In this embodiment, an angle greater than 90° is formed between the stepping plate 62 and the support plate 63. With this configuration, by setting the angle between the stepping plate 62 and the support plate 63 to be greater than 90°, the force generated when the stepping plate 62 is stepped on by a pet or user can be transmitted to the ground more stably. This reduces the risk of the stepping stool 6 tilting forward or tipping over, improving overall stability and safety during use.

[0021] In this embodiment, a retaining ring 55 is provided on the top of the feces collection box 5. The retaining ring 55 is used to hold down the garbage bag placed over the feces collection box 5. The retaining ring 55 and the feces collection box 5 are rotatably connected. Specifically, a connecting portion 54 is provided on one side of the feces collection box 5. A first connecting hole 543 and a second connecting hole 544 are provided at both ends of the connecting portion 54. A first connecting shaft 551 and a second connecting shaft 552 are provided at both ends of the retaining ring 55. The first connecting shaft 551 is rotatably provided in the first connecting hole 543. The second connecting shaft 552 is rotatably provided in the second connecting hole 544. As a result, the retaining ring 55 and the feces collection box 5 are rotatably connected. With the above configuration, a retaining ring 55 is provided that is rotatably connected to the top of the feces collection box 5. This allows the garbage bag placed over the feces collection box 5 to be held down stably, effectively preventing the garbage bag from slipping or collapsing during the process of the excrement falling in, ensuring that the excrement is reliably collected inside the feces collection box 5, and improving cleanliness and reliability during use. Furthermore, the retaining ring 55 has a rotatable connecting structure formed by a connecting shaft and a connecting hole, and can be easily reversed when the retaining ring 55 is released or when the garbage bag is removed, simplifying the garbage bag replacement process and reducing the difficulty of operation for the user.

[0022] In this embodiment, ventilation holes 56 are provided in the side walls of the feces collection box 5. Specifically, multiple ventilation holes 56 are provided in each of the two opposing side walls of the feces collection box 5. With this configuration, by providing multiple ventilation holes 56 in the two opposing side walls, when a garbage bag is placed inside the feces collection box 5, the garbage bag is encouraged to adhere tightly to the inner wall of the feces collection box 5 due to the effects of gravity and external air pressure.

[0023] In this embodiment, the upper end of the feces collection box 5 protrudes outward to form an enclosure edge 57. The retaining ring 55 comprises a top retaining edge 553 and a side retaining edge 554 connected to the top retaining edge 553. When the retaining ring 55 rotates and the top retaining edge 553 is pressed against the enclosure edge 57, the side retaining edge 554 is positioned within the third storage space 51. A relief groove 545 is provided on the side of the connecting part 54 that connects to the feces collection box 5. The relief groove 545 is used to avoid the top retaining edge 553. With the above configuration, by providing an enclosure edge 57 that protrudes outward at the upper end of the feces collection box 5, when the retaining ring 55 rotates to the operating position, its top retaining edge 553 can be reliably pressed against the enclosure edge 57, thereby effectively holding and securing the garbage bag placed over the feces collection box 5 and preventing the garbage bag from slipping or curling up during the process of the excrement falling. Furthermore, by providing a relief groove 545 on the side of the connecting section 54 that connects to the feces collection box 5, a relief space is provided for the movement of the top retaining edge 553 when the retaining ring 55 rotates, thereby avoiding structural interference and making the rotation of the retaining ring 55 smoother and more reliable.

[0024] In this embodiment, support legs 22 are detachably connected to the base 2. The cross-sectional shape of the support legs 22 is triangular. With this configuration, the triangular cross-section of the support legs 22 can form a stable support structure when subjected to force, and compared to support legs 22 of a normal shape, the triangular cross-section has superior anti-tipping and anti-tilting properties. Furthermore, by making the support legs 22 and the base 2 a detachable connection structure, they can be attached or removed according to usage needs, which is advantageous for product transportation, storage, and subsequent maintenance.

[0025] In this embodiment, a first insertion member 23 and a second insertion member 24 are detachably provided on both sides of a second opening 21 at the bottom of the base 2. The first insertion member 23 is provided with a first insertion groove 231. The second insertion member 24 is provided with a second insertion groove 241. The enclosure edge 57 of the feces collection box 5 is slidably inserted into the first insertion groove 231 and the second insertion groove 241, thereby detachably connecting the feces collection box 5 to the bottom of the base 2. Specifically, a first connecting plate 232 is provided on the side of the first insertion member 23 away from the first insertion groove 231. The first connecting plate 232 is provided with a plurality of first mounting holes 2321 at intervals. A second connecting plate 242 is provided on the side of the second insertion member 24 away from the second insertion groove 241. The second connecting plate 242 has a plurality of second mounting holes 2421 provided at intervals. A first mounting portion 25 and a second mounting portion 26 are provided on both sides of the second opening 21, respectively. The first mounting portion 25 has a plurality of first screw holes 251 provided at intervals. The second mounting portion 26 has a plurality of second screw holes 261 provided at intervals. The first insertion member 23 can be detachably attached to the bottom of the base 2 by sequentially inserting screws into the first mounting holes 2321 and the first screw holes 251, and the second insertion member 24 can be detachably attached to the bottom of the base 2 by sequentially inserting screws into the second mounting holes 2421 and the second screw holes 261. With the above configuration, a first insertion member 23 and a second insertion member 24 are provided on both sides of the second opening 21 at the bottom of the base 2, and by utilizing the sliding insertion fitting structure between the insertion groove and the surrounding edge 57 of the feces collection box 5, the feces collection box 5 can be stably and securely attached to the bottom of the base 2, while at the same time being easily detached and removed as a whole. The method of detachably fixing the insertion members to the base 2 with screws ensures the robustness of the mounting position and guarantees the load-bearing stability of the feces collection box 5 during the process of excrement falling, while also allowing the user to quickly attach and detach the feces collection box 5 according to the needs of cleaning and replacement. Furthermore, by providing the first insertion member 23 and the second insertion member 24, it becomes easy to produce and package them individually, which can reduce processing costs and transportation costs.

[0026] In this embodiment, a second reinforcing rib 2322 is provided between adjacent first mounting holes 2321. The second reinforcing rib 2322 is connected to the side wall of the first insertion member 23 and the upper surface of the first connecting plate 232. A third reinforcing rib 2422 is provided between adjacent second mounting holes 2421. The third reinforcing rib 2422 is connected to the side wall of the second insertion member 24 and the upper surface of the second connecting plate 242. Multiple fourth reinforcing ribs 252 are provided in the first mounting portion 25. Multiple fifth reinforcing ribs 262 are provided in the second mounting portion 26. With the above configuration, by providing the second reinforcing rib 2322 and the third reinforcing rib 2422 between adjacent mounting holes of the first insertion member 23 and the second insertion member 24, respectively, the structural strength of the entire insertion member and its resistance to bending and deformation are effectively improved, preventing warping or cracking of the connecting plate during screw fastening and the frequent attachment and detachment of the feces collection box 5. Furthermore, by providing the fourth reinforcing rib 252 and the fifth reinforcing rib 262 on the first mounting portion 25 and the second mounting portion 26 of the base 2, respectively, the load-bearing capacity and stability of the corresponding mounting area on the base 2 are further enhanced, making the connection between the insertion member and the base 2 more robust and reliable.

[0027] In this embodiment, a stopper member 27 is further provided at the rear end of the bottom of the base 2. When the enclosure rim 57 of the fecal collection box 5 slides into the first insertion groove 231 and the second insertion groove 241, the stopper member 27 is used to prevent the fecal collection box 5 from falling off the base 2. There are at least two stopper members 27. At least two stopper members 27 are provided side by side at the rear end of the bottom of the base 2. The stopper member 27 is provided with a plurality of sixth reinforcing ribs 271. With the above configuration, a stopper member 27 is provided at the rear end of the bottom of the base 2. When the enclosure edge 57 of the feces collection box 5 slides into the first insertion groove 231 and the second insertion groove 241, the stopper member 27 effectively restricts the position of the feces collection box 5. This prevents the feces collection box 5 from unexpectedly sliding backward due to gravity, vibration, or external pulling forces during use, thereby improving the stability and safety of the feces collection box 5 in its installed state. Furthermore, providing a sixth reinforcing rib 271 to the stopper member 27 is advantageous in increasing the structural strength and deformation resistance of the stopper member 27 itself, thereby ensuring the reliability and durability of the attachment and detachment structure of the feces collection box 5.

[0028] In this embodiment, four support legs 22 are detachably connected to the base 2. The step stool 6 is detachably connected to the feces collection box 5. The feces collection box 5 is detachably connected to the base 2. When the four support legs 22 are removed from the base 2, the step stool 6 is removed from the feces collection box 5, and the feces collection box 5 is removed from the base 2, the four support legs 22, the step stool 6, the pet toilet instruction manual, the adapter, and the garbage bag can be stored in the third storage space 51 of the feces collection box 5. When the step stool 6 is stored in the third storage space 51, the height of the step stool 6 does not exceed the height of the third storage space 51. With the above configuration, by making the support legs 22, the step stool 6, and the feces collection box 5 all detachable in this embodiment, the pet toilet can be disassembled modularly when not in use or during transport. Furthermore, the four support legs 22, step stool 6, instruction manual, adapter, and garbage bag are all stored together in the third storage space 51 of the feces collection box 5, and the height of the step stool 6 is restricted to be below the height of the third storage space 51, thereby avoiding interference during storage. This structure significantly reduces the overall packaging volume of the product, making it easier to transport, store, and carry. At the same time, it reduces the risk of parts scattering or being lost, improving the product's storage convenience, logistical suitability, and overall user experience.

[0029] In this embodiment, the sieve assembly 3 includes a connecting portion 31 and a sieve mesh portion 32. The connecting portion 31 is connected to the inner wall of the drum 1. The sieve mesh portion 32 is located between the connecting portion 31 and the first storage space 12. The sieve mesh portion 32 has a plurality of inclined sieve holes 321. Specifically, the plurality of sieve holes 321 include a first group of sieve holes 3211 and a second group of sieve holes 3212. The sieve holes 321 of the first group of sieve holes 3211 are provided along a first inclination direction, and the sieve holes 321 of the second group of sieve holes 3212 are provided along a second inclination direction, and the first and second inclination directions are different from each other. Furthermore, the first group of sieve holes 3211 and the second group of sieve holes 3212 are provided symmetrically with respect to the central axis of the sieve mesh portion 32. The first and second inclination directions are provided, respectively, inclined from opposite sides of the sieve mesh portion 32 toward the central region of the sieve mesh portion 32. In addition, the central portion of the sieve assembly 3 is recessed toward the inner wall of the drum 1, forming a flow guide passage 33. The sieve holes 321 are strip-shaped inclined sieve holes 321. With the above configuration, by providing the first group of sieve holes 3211 and the second group of sieve holes 3212 arranged along different inclination directions and symmetrically to each other in the sieve mesh portion 32, the pet litter can stably gather in the center of the sieve mesh and pass smoothly through the sieve holes 321 during the rotation process of the drum 1 due to gravity and the inclined guiding effect of the sieve holes 321. On the other hand, since the excrement is effectively retained on the outside of the sieve mesh, the sieving efficiency is improved and the probability of clogging is reduced. At the same time, the guide passage 33, formed by the central part of the sieve assembly 3 being recessed toward the inner wall of the drum 1, further guides the pet sand that has passed through the sieve holes 321, causing it to flow intensively and fall stably into the first containment space 12. This prevents the pet sand from dispersing and accumulating or lingering on the sieve mesh, making the sieving process smoother and more reliable. In turn, this improves the stability of pet sand collection and the overall cleaning effect, contributing to improved automatic cleaning performance of the pet toilet and the user experience.

[0030] In this embodiment, the connecting portion 31 comprises a first blocking plate 311 and a second blocking plate 312. One side of the first blocking plate 311 is connected to the sieve portion 32. The central portion of the other side of the first blocking plate 311 is connected to the central portion of the drum 1. Both ends of the other side of the first blocking plate 311 are connected to both ends of the drum 1 via the second blocking plate 312. The angle between the second blocking plate 312 and the first blocking plate 311 is acute, right, or obtuse. At the same time, the second blocking plate 312 also serves to block the pet litter, preventing it from scattering to the outside when the drum 1 rotates.

[0031] In this embodiment, the drive unit 4 comprises a drive motor 41, a drive gear 42, and a driven gear 43. The drive motor 41 has a drive shaft 411. The drive gear 42 is fitted onto the drive shaft 411. The driven gear 43 is provided on the drum 1 and meshes with the drive gear 42. As a result, the rotation of the drive shaft 411 rotates the drive gear 42, the rotation of the drive gear 42 rotates the driven gear 43, and the rotation of the driven gear 43 rotates the drum 1 on the base 2. The drive motor 41 and the drive gear 42 are provided on the base 2. A relief groove 201 is provided on the side of the base 2 adjacent to the drive motor 41. At least a portion of the drive gear 42 extends into the relief groove 201. The driven gear 43 is located within the relief groove 201 and rotates in mesh with the drive gear 42. Furthermore, a stopper projection 101 is provided on the side of the drum 1 adjacent to the relief circular tank 201. The stopper projection 101 is used to cover the gap 102 that occurs between the side edge of the drum 1 and the relief circular tank 201. The stopper projection 101 is an arc-shaped projection that fits the relief circular tank 201. The stopper projection 101 is located in the center of the side edge of the drum 1. With the above configuration, by providing a stopper projection 101 that fits the relief circular tank 201 on the side of the drum 1 adjacent to the relief circular tank 201, and having the stopper projection 101 cover the gap 102 that occurs between the side edge of the drum 1 and the relief circular tank 201, it is possible to effectively prevent pet litter, excrement, or foreign matter from entering the meshing area of ​​the drive gear 42 and the driven gear 43, thereby reducing the risk of jamming, wear, or transmission abnormalities, and ultimately improving the operating stability and reliability of the drive unit 4. At the same time, by providing the stopper projection 101 in the center of the side edge of the drum 1, it is possible to achieve a compact configuration without affecting the normal rotation of the drum 1, which is advantageous in extending the service life of the drive unit 4 and thereby improving the overall safety and durability of the pet toilet.

[0032] In this embodiment, the pet toilet further includes a control board 44 and a Hall sensor 45 provided on the base 2. The Hall sensor 45 and the drive unit 4 are electrically connected to the control board 44. The Hall sensor 45 is used to detect the rotational position of the drum 1. The Hall sensor 45 is provided on the side of the base 2 adjacent to the drive unit 4, and is arranged alongside the drive gear 42 and the driven gear 43. With the above configuration, by providing the control board 44 on the base 2 and detecting the rotational position of the drum 1 using the Hall sensor 45, the control board 44 can acquire the rotational state and position information of the drum 1 in real time, thereby enabling high-precision control of the start / stop and rotation angle of the drive unit 4. Furthermore, by providing the Hall sensor 45 on the side adjacent to the drive unit 4 and arranging it alongside the drive gear 42 and the driven gear 43, the space occupied by the components inside the base 2 can be effectively reduced. This enables the compact integration of the Hall sensor 45 and the transmission structure, contributing to a reduction in the installation space of the base 2 and the entire device, and consequently reducing the overall volume of the pet toilet, improving the compactness of the product configuration and space utilization, and significantly reducing transportation costs.

[0033] In this embodiment, the Hall sensor 45 has a magnetic detection area 431 and a first magnetic pole 432 and a second magnetic pole 433. The magnetic detection area 431 is provided on the base 2. The first magnetic pole 432 and the second magnetic pole 433 are provided on the drum 1. When the drum 1 rotates to the initial position, the first magnetic pole 432 is located in the magnetic detection area 431. When the drum 1 rotates to the excretion position, the second magnetic pole 433 is located in the magnetic detection area 431. With the above configuration, when the magnetic detection area 431 detects the second magnetic pole 433, it means that the drum 1 has rotated to the excretion position, and the control board 44 stops the rotation of the drum 1 based on the signal fed back from the Hall sensor 45 and discharges the excrement into the feces collection box 5. After the excrement is discharged from the first opening 11, the control board 44 reverses the rotation of the drum 1 from the excretion position towards the initial position. When the magnetic detection area 431 detects the first magnetic pole 432, the drum 1 has rotated to its initial position. Based on the signal fed back from the Hall sensor 45, the control board 44 stops the rotation of the drum 1 and holds it in its initial position, allowing the pet to enter and exit and use the toilet.

[0034] In this embodiment, the base 2 includes a main body 28, a first support arm 281, and a second support arm 282. The first support arm 281 is connected to one side of the main body 28. The second support arm 282 is connected to the other side of the main body 28. The first support arm 281 is used to support one side of the drum 1. The second support arm 282 is used to support the other side of the drum 1. The drive unit 4 is used to rotate the drum 1 between the first support arm 281 and the second support arm 282. The first support arm 281 is provided with a first support groove 2811. The second support arm 282 is provided with a second support groove 2821. A first support shaft 14 is provided on one side of the drum 1. A second support shaft 15 is provided on the other side of the drum 1. The first support shaft 14 is positioned in the first support groove 2811 and is rotatable within the first support groove 2811. The second support shaft 15 is positioned in the second support groove 2821 and is rotatable within the second support groove 2821. Multiple rollers 2812 are provided in the first support groove 2811. The rollers 2812 support the first support shaft 14. With the above configuration, by providing support grooves in the first support arm 281 and the second support arm 282 of the base 2, and providing support shafts on both sides of the drum 1 that fit with these grooves, the drum 1 can be stably mounted on the base 2 and rotation can be ensured. At the same time, by installing multiple rollers 2812 in the first support groove 2811 and supporting the first support shaft 14 by rolling with the rollers 2812, sliding friction during the rotation process of the drum 1 can be effectively converted into rolling friction. This reduces rotational resistance and wear, improves the rotational stability and smoothness of drum 1, and ultimately enhances the operational reliability and user experience of the pet toilet.

[0035] In this embodiment, the pet toilet further includes a first opening / closing lid 283. One end of the first opening / closing lid 283 is rotatably connected to one side of the first support arm 281. The other end of the first opening / closing lid 283 is detachably connected to the other side of the first support arm 281 via a first pin insertion device 7. The first opening / closing lid 283 covers the first support groove 2811 and is used to lock the first support shaft 14 into the first support groove 2811. A first insertion opening 2813 is provided at one end of the first support arm 281 that is detachably connected to the first opening / closing lid 283. The first pin insertion device 7 includes a first pin insertion pin 71 provided on the first opening / closing lid 283 and a first push rod 72 connected to the first pin insertion pin 71. A first slide hole 2831 is provided on the outer wall of the first opening / closing lid 283. The first push rod 72 penetrates the first slide hole 2831 and is slidable within the first slide hole 2831. The first push rod 72 is used to drive and slide the first insertion pin 71 to insert into or remove from the first insertion port 2813, thereby detachably connecting one end of the first opening / closing lid 283 and one end of the first support arm 281. The first insertion pin device 7 further includes a first positioning plate 73 connected to the first insertion pin 71 and the first push rod 72. On the inward-facing side of the first positioning plate 73, a first positioning groove 731, a first positioning passage 732, and a second positioning groove 733 are provided in that order. A first mounting member 2832 is fixedly installed inside the first opening / closing lid 283. The first mounting member 2832 is provided with a first elastic positioning projection 2833. When the first insertion pin 71 is driven and slid, the first elastic positioning projection 2833 is moved along the first positioning passage 732 to the first positioning groove 731 and locked in place, the first insertion pin 71 disengages from the first insertion opening 2813. When the first insertion pin 71 is driven and slid, the first elastic positioning projection 2833 is moved along the first positioning passage 732 to the second positioning groove 733 and locked in place, the first insertion pin 71 is inserted into the first insertion opening 2813. With the above configuration, by providing a first opening / closing cover 283 that is rotatably and detachably connected to the first support arm 281 and combining it with the first insertion pin device 7 having a two-stage positioning function, the first support shaft 14 can be reliably restricted into the first support groove 2811 as needed.Furthermore, if maintenance or removal of drum 1 is required, the restricted state can be quickly released, thereby enabling easy installation and removal of drum 1. At the same time, the first pin insertion device 7, through the engagement of the first positioning groove 731, the first positioning passage 732, and the second positioning groove 733 with the first elastic positioning projection 2833, forms stable positioning in both the insertion and removal states of the pin, preventing accidental detachment and improving the reliability of the connection. The above configuration ensures the rotational stability of drum 1 while significantly improving the convenience of assembly, maintenance, and replacement of drum 1, reducing the difficulty of use and repair, and enhancing the overall structural reliability and user experience of the pet toilet.

[0036] In this embodiment, the first pin insertion device 7 further includes a first spring mounting column 74 connected to the first pin insertion 71. A first limit block 2834 is fixedly installed on the inner wall of the first opening / closing lid 283. One end of the spring can be fitted onto the first spring mounting column 74, and the other end of the spring can contact the first limit block 2834 to restrict its position. When the first opening / closing lid 283 rotates to a position where the first pin insertion 71 and the first insertion opening 2813 correspond, the spring drives the first pin insertion 71 to slide and insert it into the first insertion opening 2813. With the above configuration, by providing the first pin insertion device 7 with a spring mounting column, a spring, and a limit block that cooperates with it, the first pin insertion pin 71 automatically returns to its original position due to the elastic action of the spring and is inserted into the first insertion opening 2813 when the first opening / closing cover 283 rotates to a position corresponding to the first insertion opening 2813. This achieves automatic locking of the first opening / closing cover 283 and the first support arm 281, improving the convenience and reliability of assembly and disassembly. At the same time, the cooperation of the spring and the limit block allows the first pin insertion pin 71 to stably maintain its inserted state, preventing the first opening / closing cover 283 from opening unintentionally even when vibrations or external forces are applied during use.

[0037] In this embodiment, the pet toilet further includes a second opening / closing lid 284. One end of the second opening / closing lid 284 is rotatably connected to one side of the second support arm 282. The other end of the second opening / closing lid 284 is detachably connected to the other side of the second support arm 282 via a second pin device 8. The second opening / closing lid 284 covers the second support groove 2821 and is used to lock the second support shaft 15 into the second support groove 2821. A second insertion opening 2822 is provided at the end of the second support arm 282 that is detachably connected to the second opening / closing lid 284. The second pin device 8 includes a second pin 81 provided on the second opening / closing lid 284 and a second push rod 82 connected to the second pin 81. A second slide hole 2841 is provided on the outer wall of the second opening / closing lid 284. The second push rod 82 penetrates the second slide hole 2841 and is slidable within the second slide hole 2841. The second push rod 82 is used to drive the second insertion pin 81 to slide, insert it into the second insertion opening 2822, or to disengage it from the second insertion opening 2822, thereby detachably connecting one end of the second opening / closing lid 284 and one end of the second support arm 282. The second insertion pin device 8 further includes a second positioning plate 83 connected to the second insertion pin 81 and the second push rod 82. A third positioning groove 831, a second positioning passage 832, and a fourth positioning groove 833 are provided in order on the inward-facing side of the second positioning plate 83. A second mounting member 2842 is fixedly installed inside the second opening / closing lid 284. A second elastic positioning projection 2843 is provided on the second mounting member 2842. When the second insertion pin 81 is driven and slid, the second elastic positioning projection 2843 is moved along the second positioning passage 832 to the third positioning groove 831 and locked in place, the second insertion pin 81 disengages from the second insertion opening 2822. When the second insertion pin 81 is driven and slid, the second elastic positioning projection 2843 is moved along the second positioning passage 832 to the fourth positioning groove 833 and locked in place, the second insertion pin 81 is inserted into the second insertion opening 2822. With the above configuration, the second support shaft 15 can be reliably positioned within the second support groove 2821 using the same principle, thereby ensuring stable support for the drum 1 during operation and preventing axial displacement and rattling during rotation.At the same time, it facilitates the user to quickly open the second opening / closing cover 284 when performing maintenance or removing drum 1.

[0038] In this embodiment, the second pin insertion device 8 further includes a second spring mounting column 84 connected to the second pin insertion 81. A second limit block 2844 is fixedly installed on the inner wall of the second opening / closing lid 284. One end of the spring can be fitted onto the second spring mounting column 84, and the other end of the spring can contact the second limit block 2844 to restrict its position. When the second opening / closing lid 284 is rotated and the second pin insertion 81 and the second insertion opening 2822 reach a corresponding position, the spring pushes out the second pin insertion 81, allowing it to slide and be inserted into the second insertion opening 2822. With the above configuration, the combination of the spring and the limit block can stably restrict the operating stroke of the second pin insertion 81, ensuring accuracy of the pin insertion position and stability of the connection. This prevents the second opening / closing lid 284 from accidentally falling off during use, improving the safety and overall reliability of the drum 1 support structure.

[0039] In this embodiment, a roller holder 141 is fitted onto the first support shaft 14. The roller holder 141 is provided with a plurality of rollers 2812. The plurality of rollers 2812 support the first support shaft 14, thereby allowing the first support shaft 14 to rotate within the roller holder 141. The roller holder 141 is located within the first support groove 2811. The second support shaft 15 is located within the second support groove 2821, and the second support shaft 15 is rotatable within the second support groove 2821. The first opening / closing cover 283 covers the first support groove 2811 and is used to lock the roller holder 141 into the first support groove 2811. With the above configuration, the installation of the rollers 2812 is effectively realized, and the rollers 2812 can be easily replaced, removed, and cleaned via the roller holder 141.

[0040] In this embodiment, the pet toilet further includes an internal infrared detection device 10 and a control board 44 provided on the base 2. The internal infrared detection device 10 is electrically connected to the control board 44 and is used to detect whether or not a pet has entered the second opening 21, thereby preventing the pet from getting trapped. The internal infrared detection device 10 is positioned above the second opening 21. When the first opening 11 rotates with the drum 1 from the defecation position to the initial position, and the internal infrared detection device 10 detects that a pet has entered the second opening 21, the control board 44 controls the drive device 4 to reverse the rotation of the drum 1 and the first opening 11 to the defecation position. Specifically, the base 2 has a front end 202 and a rear end 203 opposite to it. When the first opening 11 is in the initial position, it faces the front end 202. The internal infrared detection device 10 is provided on the inner wall of the base 2 and is located on the side closer to the rear end 203. With the above configuration, the internal infrared detection device 10 is installed inside the base 2 and above the second opening 21, and by controlling the drive unit 4 in cooperation with the control board 44, it is possible to detect in real time whether a pet has entered the second opening 21 or the feces collection passage during the process of the drum 1 returning from the excretion position to the initial position. If the entry of a pet is detected, the control board 44 immediately controls the drive unit 4 to reverse the rotation of the drum 1 to the excretion position. This avoids the risk of the pet being caught or crushed while the drum 1 is rotating, effectively improving the safety and reliability of using the pet toilet. It is particularly suitable for active pets and small pets, reducing the possibility of accidents and increasing user confidence in the product and the overall user experience.

[0041] Furthermore, the base 2 includes a main body 28, a first support arm 281, and a second support arm 282. The first support arm 281 is connected to one side of the main body 28. The second support arm 282 is connected to the other side of the main body 28. The first support arm 281 is used to support one side of the drum 1. The second support arm 282 is used to support the other side of the drum 1. The drive unit 4 is used to rotate the drum 1 between the first support arm 281 and the second support arm 282. The internal infrared detection device 10 includes an internal infrared opposing unit 1010. The internal infrared opposing unit 1010 includes an internal infrared emitter 1011 and an internal infrared receiver 1012. The internal infrared emitter 1011 is provided on the first support arm 281. The internal infrared receiver 1012 is provided on the second support arm 282. With the above configuration, the internal infrared detection device 10 is in the form of an internal infrared opposing unit 1010, and by arranging it on the first support arm 281 and the second support arm 282 respectively, the infrared emitter and infrared receiver face each other sideways to emit and receive infrared light, forming a stable and complete detection area, and accurately covering the important passage space inside the second opening 21. If a pet enters the area, it is detected quickly and reliably, and an accurate safety signal is provided to the control board 44, preventing the pet from being caught or startled while the drum 1 is rotating. At the same time, this opposing arrangement method has a simple structure, stable installation, is less affected by the accumulation of pet litter or shielding on one side, improves the sensitivity and reliability of detection, and further enhances safety and intelligent control effects when using the pet toilet.

[0042] Furthermore, when the drive unit 4 rotates the drum 1 between the first support arm 281 and the second support arm 282, and the inner infrared opposing unit 1010 is exposed, the inner infrared opposing unit 1010 enters a detection state. With the above configuration, the inner infrared opposing unit 1010 enters a detection state only when the drum 1 has rotated to a specific position and the inner infrared opposing unit 1010 is exposed, thus avoiding false judgments and invalid detections due to continuous detection in unnecessary states.

[0043] Furthermore, the pet toilet includes a first inner mounting box 1013 located within the first support arm 281 and a second inner mounting box 1014 located within the second support arm 282. The inner infrared emitter 1011 is located within the first inner mounting box 1013. The inner infrared receiver 1012 is located within the second inner mounting box 1014. With this configuration, by arranging the inner infrared emitter 1011 and the inner infrared receiver 1012 in mounting boxes located inside the first support arm 281 and the second support arm 282, respectively, a good shielding and protective effect is achieved for the infrared detection element, preventing a decrease in detection accuracy and a shortening of service life due to the intrusion of pet litter, excrement, and dust. At the same time, it is advantageous to make the layout more compact and stabilize the relative positions of the emitter and receiver, thereby improving the reliability of the opposing detection system.

[0044] In this embodiment, the pet toilet further includes a first bottom infrared detection device 20, a second bottom infrared detection device 30, and a third bottom infrared detection device 40 provided on the base 2. The first bottom infrared detection device 20, the second bottom infrared detection device 30, and the third bottom infrared detection device 40 are electrically connected to a control board 44. The first bottom infrared detection device 20, the second bottom infrared detection device 30, and the third bottom infrared detection device 40 are used to detect whether or not a pet has entered the second opening 21.

[0045] In this embodiment, when the first opening 11 rotates with the drum 1 from the excretion position to the initial position, and the first bottom infrared detection device 20 or the second bottom infrared detection device 30 detects that a pet has entered the second opening 21, the control board 44 stops the operation of the drive device 4, thereby stopping the rotation of the drum 1. Also, when the first opening 11 rotates with the drum 1 from the excretion position to the initial position, and the third bottom infrared detection device 40 detects that a pet has entered the second opening 21, the control board 44 controls the drive device 4 to reverse the rotation of the drum 1 and the first opening 11 to the excretion position. Of these, the third bottom infrared detection device 40 has the highest priority.

[0046] With the above configuration, multiple bottom infrared detection devices are installed in the second opening 21 of the base 2 and controlled in conjunction with the control board 44 and the drive unit 4, thereby achieving highly accurate detection and identification of pets entering the second opening 21 area. Specifically, if the first bottom infrared detection device 20 or the second bottom infrared detection device 30 detects a pet entering the second opening 21 during the process of the drum 1 rotating from the excretion position to the initial position, the control board 44 quickly stops the operation of the drive unit 4 and stops the rotation of the drum 1, thereby avoiding the risk of pets being trapped due to the continued rotation of the drum 1. On the other hand, if the third bottom infrared detection device 40 detects a pet entering the second opening 21, the control board 44 controls the drive unit 4 to reverse the rotation of the drum 1 and the first opening 11 to the excretion position. This multi-detection point coordinated control structure design not only improves the accuracy of identifying pets entering and exiting, but also significantly increases the safety and reliability of the pet toilet during operation, effectively reducing potential risks due to malfunctions.

[0047] In this embodiment, when the first opening 11 rotates with the drum 1 from the discharge position to the initial position and the drum 1 covers the second opening 21, if any one of the first bottom infrared detection device 20, the second bottom infrared detection device 30, and the third bottom infrared detection device 40 is triggered, the control board 44 controls the drive device 4 to reverse-rotate the drum 1 and the first opening 11 to the discharge position and hold them there for a predetermined time, thereby opening the second opening 21. If none of the first bottom infrared detection device 20, the second bottom infrared detection device 30, and the third bottom infrared detection device 40 are triggered within the predetermined time, after the predetermined time has elapsed, the control board 44 controls the drive device 4 to rotate the first opening 11 with the drum 1 from the discharge position to the initial position. Here, the predetermined time can be set within the range of 10 seconds to 100 seconds, and preferably the predetermined time is 40 seconds. With the above configuration, if any of the bottom infrared detection devices detect that a pet has entered the second opening 21, the control board 44 quickly controls the drive unit 4 to reverse the rotation of the drum 1, reversing the rotation of the first opening 11 to the defecation position, opening the second opening 21, and holding it there for 40 seconds. If no infrared detection device is triggered within 40 seconds, the drum 1 begins to rotate back to its initial position. This prevents pets from remaining inside the second opening 21, improving safety and intelligence levels when using the pet toilet.

[0048] In this embodiment, the first bottom infrared detection device 20 includes a first bottom infrared opposing unit 2010 located in the second aperture 21. The first bottom infrared opposing unit 2010 includes a first bottom infrared emitter 2011 and a first bottom infrared receiver 2012. The first bottom infrared emitter 2011 and the first bottom infrared receiver 2012 are each installed on opposite left and right sides of the second aperture 21. The second bottom infrared detection device 30 includes a second bottom infrared opposing unit 3010 located in the second aperture 21. The second bottom infrared opposing unit 3010 includes a second bottom infrared emitter 3011 and a second bottom infrared receiver 3012. The second bottom infrared emitter 3011 and the second bottom infrared receiver 3012 are each installed on opposite left and right sides of the second aperture 21. The third bottom infrared detection device 40 includes a third bottom infrared opposing unit 4010 positioned in the second opening 21. The third bottom infrared opposing unit 4010 includes a third bottom infrared emitter 4011 and a third bottom infrared receiver 4012. The third bottom infrared emitter 4011 and the third bottom infrared receiver 4012 are installed on opposite left and right sides of the second opening 21, respectively. Furthermore, the first bottom infrared detection device 20, the second bottom infrared detection device 30, and the third bottom infrared detection device 40 have different vertical installation heights. With the above configuration, by arranging multiple independent bottom infrared opposing units opposite each other on both the left and right sides of the second opening 21, the control board 44 can detect and determine the pet's entry status from different positions, different heights, or different entry paths at multiple points, thereby improving the accuracy and reliability of identifying the pet's approach to or entry into the second opening 21. The coordinated operation of multiple bottom infrared opposing units effectively reduces the risk of detection failures or misjudgments caused by shielding, changes in posture, or short-term interference in a single infrared detection device. This makes the control of starting, stopping, and reversing the drum 1 by the drive unit 4 safer and more stable, further enhancing safety when used by pets and the overall operational reliability of the device. In addition, the first bottom infrared detection device 20, the second bottom infrared detection device 30, and the third bottom infrared detection device 40 can also identify the degree of excrement accumulation in the feces collection box 5, thereby enabling a function to detect and indicate whether the feces collection box 5 is nearly full or full.This makes it easier for users to clean the feces collection box 5 in a timely manner and further improves the convenience of using the pet toilet by avoiding overflow, worsening odors, or impact on the normal use of the pet toilet caused by excessive filling of excrement.

[0049] In this embodiment, the base 2 has a front end 202 and a rear end 203 opposite to it. The first opening 11 is positioned facing the front end 202 when in its initial position. The first bottom infrared detection device 20 and the second bottom infrared detection device 30 are installed on the side closer to the rear end 203. The third bottom infrared detection device 40 is installed on the side closer to the front end 202. When the first opening 11 rotates with the drum 1 from the excretion position to the initial position, the drum 1 passes over the third bottom infrared detection device 40, the second bottom infrared detection device 30, and the first bottom infrared detection device 20 in that order. With the above configuration, stage-by-stage and position-by-position detection of the pet's entry into the second opening 21 is realized. With this arrangement, the entry position and timing of the pet can be determined with higher accuracy in conjunction with the rotation sequence of the drum 1, and the reliability and safety of the pinch prevention control are improved by the control board 44 executing different control measures such as reverse rotation or stopping according to the detection result.

[0050] In this embodiment, the pet toilet further includes a first bottom mounting box 3013, a second bottom mounting box 3014, a third bottom mounting box 2013, and a fourth bottom mounting box 2014. The first bottom mounting box 3013 and the second bottom mounting box 3014 are each positioned opposite each other on the left and right sides of the second opening 21. The third bottom mounting box 2013 and the fourth bottom mounting box 2014 are each positioned opposite each other on the left and right sides of the second opening 21. The second bottom infrared emitter 3011 and the third bottom infrared emitter 4011 are installed inside the first bottom mounting box 3013. The second bottom infrared receiver 3012 and the third bottom infrared receiver 4012 are installed inside the second bottom mounting box 3014. The first bottom infrared emitter 2011 is installed inside the third bottom mounting box 2013. The first bottom infrared receiver 2012 is installed in the fourth bottom mounting box 2014. With this configuration, by housing and protecting the infrared device in an independent bottom mounting box, interference to the infrared device by dust, pet litter, and excrement can be effectively reduced, and the product life can be extended.

[0051] In this embodiment, when the drum 1 and the first opening 11 rotate to the defecation position and open the second opening 21, an access passage 200 is formed between the drum 1 and the base 2. The access passage 200 communicates with the second opening 21. With the above configuration, when the drum 1 and the first opening 11 rotate to the defecation position and open the second opening 21, an access passage 200 communicating with the second opening 21 is formed between the drum 1 and the base 2. Even if a pet accidentally enters the base 2 while the drum 1 is operating, it can quickly and voluntarily leave through the access passage 200, avoiding being trapped in the base 2 or the feces collection box 5, thereby improving the safety of the pet while the drum 1 is operating.

[0052] In this embodiment, the base 2 comprises a front end 202 and a rear end 203 opposite to it. The first opening 11 faces the front end 202 when in its initial position. The pet toilet further includes a tail infrared detection device 50. The tail infrared detection device 50 is installed on the rear end 203. The tail infrared detection device 50 is used to detect whether a pet has entered the second opening 21, thereby preventing the pet from getting trapped. Specifically, the tail infrared detection device 50 includes a tail infrared opposing unit 5010. The tail infrared opposing unit 5010 includes a tail infrared emitter 5011 and a tail infrared receiver 5012. The tail infrared emitter 5011 and the tail infrared receiver 5012 are positioned on opposite left and right sides of the rear end 203, respectively. Specifically, the rear end portion 203 has a first projection 2031 and a second projection 2032 located on both the left and right sides, respectively. The tail infrared emitter 5011 is installed within the first projection 2031. The tail infrared receiver 5012 is installed within the second projection 2032. With the above configuration, the tail infrared detection device 50 is installed on the rear end portion 203 of the base 2, and the forward and backward movement of the second opening 21 is detected in real time by the tail infrared opposing units 5010 located on both the left and right sides. This allows for rapid detection when a pet enters from the rear end portion 203 or approaches the rear end of the base 2, providing effective prediction and protection against the potential risk of entrapment during the rotation process of the drum 1.

[0053] In this embodiment, the pet toilet further includes a first tail mounting box 5013 and a second tail mounting box 5014. The first tail mounting box 5013 and the second tail mounting box 5014 are installed on opposite left and right sides of the rear end 203, respectively. The tail infrared emitter 5011 is installed inside the first tail mounting box 5013. The tail infrared receiver 5012 is located inside the second tail mounting box 5014.

[0054] In this embodiment, the first support arm 281 is further provided with a left-side infrared emitter 60. The second support arm 282 is provided with a right-side infrared receiver 70. The left-side infrared emitter 60 and the right-side infrared receiver 70 are used to detect whether or not a pet has entered the first containment space 12 of the drum 1. Furthermore, the first support shaft 14 has a first viewing window 142. The second support shaft 15 has a second viewing window 151 that faces the first viewing window 142. The left-side infrared emitter 60 is installed in the first viewing window 142. The right-side infrared receiver 70 is installed in the second viewing window 151. As a result, the left-side infrared emitter 60 and the right-side infrared receiver 70 are positioned opposite each other. With the above configuration, by providing viewing windows opposite the first support shaft 14 and the second support shaft 15, a precise opposing detection relationship between the left infrared emitter 60 and the right infrared receiver 70 is achieved, avoiding a decrease in detection reliability due to structural shielding or misalignment. This enables real-time detection of whether or not a pet has entered the first containment space 12 of the drum 1, and also allows detection of whether or not the drum 1 is mounted on the base 2.

[0055] In this embodiment, the pet toilet further includes a mat body 9. The mat body 9 includes a flexible mat 91. A mat enclosure edge 92 is connected to the periphery of the flexible mat 91 so as to surround it.

[0056] Of these, the mat enclosure rim 92 is configured to be detachably connected to the inner wall of the drum 1 of the pet toilet, and the mat body 9 is detachably installed inside the drum 1. With this configuration, the flexible mat 91 provides a comfortable stepping surface and waste receiving surface for pets, while also stably adhering to the inner wall of the drum 1 and preventing displacement during use. Furthermore, the detachable connection structure between the mat enclosure rim 92 and the inner wall of the drum 1 makes it convenient for the user to remove the entire mat body 9 for washing, replacement, or maintenance as needed, thereby effectively improving the cleanability and hygiene of the inside of the drum 1 and reducing the persistence of unpleasant odors.

[0057] In this embodiment, the inner wall of the drum 1 is provided with an upper stopper edge 111 and a lower stopper edge 112, which are provided along the circumferential direction. An inner wall locking groove 113 is formed between the upper stopper edge 111 and the lower stopper edge 112. The side of the mat enclosure edge 92 is structured to fit into the inner wall locking groove 113 and engage with its interior. A limit member 921 is provided on the mat enclosure edge 92. A limit mating member 1131 is provided on the inner wall locking groove 113. The limit member 921 and the limit mating member 1131 cooperate with each other to restrict the relative lateral displacement of the mat enclosure edge 92 with respect to the upper stopper edge 111 and the lower stopper edge 112. Specifically, the limit member 921 includes a limit projection 9211 provided on the mat enclosure edge 92. The limit mating member 1131 includes a limit protrusion 1132 provided in the inner wall locking groove 113 and engaging with the limit projection 9211. The limit member 921 further includes a limit recess 9212 provided in the mat enclosure edge 92. The limit mating member 1131 includes a limit recess 1133 provided in the inner wall locking groove 113 and engaging with the limit recess 9212. There are four limit projections 9211. The four limit projections 9211 are distributed along the circumferential direction of the mat enclosure edge 92. There are four limit recesses 9212. The four limit recesses 9212 are distributed along the circumferential direction of the mat enclosure edge 92. With the above configuration, the upper stopper edge 111 and the lower stopper edge 112 provided on the inner wall of the drum 1 form an inner wall locking groove 113, allowing the mat enclosure edge 92 of the mat body 9 to be securely locked and fitted to the inner wall of the drum 1. The installation of the limit member 921 and the limit mating member 1131 effectively restricts the relative lateral displacement of the mat enclosure edge 92, ensuring that the mat body 9 is stably held and does not shift position when the drum 1 rotates or is in use. At the same time, the fitting of the limit projection 9211 with the limit convex groove 1132 and the limit recess 9212 with the limit concave groove 1133 makes the mounting position of the mat body 9 even more precise and reliable, improving safety and comfort during use, and also making removal and cleaning easier.

[0058] In this embodiment, the flexible mat 91 is sewn to the mat enclosure edge 92 by sewing thread 911. With this configuration, the flexible mat 91 and the mat enclosure edge 92 are fixed together via the sewing thread 911, making the overall structure of the mat body 9 robust and preventing the flexible mat 91 from shifting position or falling off when the drum 1 is rotating or when the pet is in use.

[0059] In this embodiment, the flexible mat 91 is a woven fabric flexible mat 91. Preferably, the flexible mat 91 is a woven fabric flexible mat 91 with a density of 300D. With the above configuration, by adopting a woven fabric flexible mat 91 with a density of 300D, it is possible to ensure a certain level of softness and comfort while exhibiting excellent abrasion resistance and support, providing a comfortable tactile sensation for pets during use, and making the mat body 9 less prone to deformation or damage, thereby improving the lifespan of the pet toilet and the overall user experience.

[0060] In this embodiment, a first waterproof coating 912 is applied to the upper surface of the flexible mat 91. A second waterproof coating 913 is applied to the lower surface of the flexible mat 91. With this configuration, the application of waterproof coatings to both the upper and lower surfaces of the flexible mat 91 effectively prevents liquid from penetrating into the interior of the mat body 9, thereby maintaining the cleanliness of the mat body 9, reducing unpleasant odors and bacterial growth, improving the hygiene and durability of the pet toilet, and simultaneously making cleaning and maintenance easier.

[0061] In another embodiment, the flexible mat 91 may be a silicone flexible mat 91.
