Description

Technical Field

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

[0002] In pet-friendly environments, litter boxes are provided to facilitate pets' toileting needs. Taking a cat litter box as an example (sometimes referred to as a "cat litter box" for clarity), a typical cat litter box has a compartment for the cat to use (sometimes called a "litter chamber" for clarity). To prevent cat excrement from contaminating the main body of the compartment, a protective mat is usually laid inside, on which excrement-aggregating particles (such as cat litter) are placed. After the cat defecates in the compartment, the excrement combines with the cat litter to form clumps. When cleaning the inside of the compartment is necessary, these clumps of cat litter are removed, thus cleaning up the cat excrement as well. Because the excrement in the litter box compartment has a strong odor, to reduce the workload for cat owners, a method has been proposed to rotate or tilt the compartment to remove these clumps of cat litter. However, when attempting to rotate and tilt the chamber to clear clumps of litter, sometimes clumps of litter get stuck between the protective pad and the main body of the chamber and do not fall out. After the chamber is rotated in the opposite direction, these clumps of litter return to the chamber. Utility Model Content

[0003] This invention addresses the aforementioned technical problems by providing a pet toilet compartment that prevents clumps of pet excrement from getting stuck during descent when cleaning them. Furthermore, this invention also provides a pet toileting device incorporating this pet toilet compartment.

[0004] According to the first aspect of this utility model, a pet toilet compartment includes: a main body, mounting components, and a protective pad.

[0005] The main body has a bottom wall portion and side walls surrounding the bottom wall portion. The bottom wall portion and the side walls together define a toilet space, and the side walls have a first entrance / exit allowing pets to enter and exit.

[0006] The mounting member is located within the toilet space and surrounds the sidewall portion circumferentially. The mounting member has an arched portion, a first extension, and a second extension. The arched portion is formed at the center of the mounting member's axial direction, arching radially inward, and a receiving portion is formed between the arched portion and the sidewall portion. The first extension, located on the side opposite to the arched portion and the bottom wall portion, has one end smoothly connected to the arched portion, and the other end extends relative to the arched portion on the axial side of the mounting member and radially outward, and the other end of the first extension is sealed between itself and the inner surface of the sidewall portion. The second extension, located on the same side as the arched portion and the bottom wall portion, has one end smoothly connected to the arched portion, and the other end extends relative to the arched portion on the opposite axial side of the mounting member and radially outward,.

[0025] In the description of this embodiment, unless otherwise explicitly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this embodiment in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 8 and mainly refer to Figure 7 , Figure 8Pet toileting devices can be house-type devices. Pets using such devices may include, for example, cats, dogs, rabbits, and hamsters. Typically, when a pet toileting device is used for a cat's toileting behavior, it is sometimes called a "litter box." The pet toileting device includes a base 100 and a chamber 200 disposed on the base 100. The base 100 can be supported on a floor, table, or any other location that allows easy access for the pet. The base 100 includes a pedestal 101, which forms a collection space 102 for collecting pet excrement. The chamber 200, acting as a house, is disposed on the pedestal 101 of the base 100. The chamber 200 forms a toileting space 201 and a first entrance / exit 202 allowing the pet to enter and exit. The pet enters the toileting space 201 through the first entrance / exit 202 and uses the toilet within it. In addition, an opening 103 is formed between the base 100 and the cabin section 200. The opening 103 is formed on the base 101 for example, and the opening 103 can be opened or closed, for example, through a door section 500 having a double door structure.

[0027] The compartment 200 has an outer shell 203 and a pet toilet compartment 204 (sometimes simply referred to as compartment 204) rotatably mounted within the outer shell 203. The outer shell 203 is supported on a base 101 of a base base 100 and communicates with a collection space 102 via an opening 103. The outer shell 203 and compartment 204 are generally hemispherical in shape; in other words, both the outer shell 203 and compartment 204 are open. A first inlet / outlet 202 is formed in the main body 205 of compartment 204. Furthermore, a second inlet / outlet 206 with a shape substantially the same as the first inlet / outlet 202 is formed on the outer shell 203. When compartment 204 is rotated so that the first inlet / outlet 202 and the second inlet / outlet 206 of outer shell 203 are in substantially the same position, the pet can enter and exit the toilet space 201. When the chamber 204 rotates to the position where the first inlet / outlet 202 and the opening 103 are connected, the excrement falls from the chamber 204 and into the collection space 102 through the opening 103.

[0028] Continue to refer to Figures 1 to 6 and supplementary reference Figure 7 as well as Figure 8 Additionally, it should be noted that, for ease of illustration, section lines are not necessarily strictly assigned to each section in the sectional views, and the viewing angle of the sectional views may be adjusted as needed.

[0029] The compartment 204 of the embodiment includes a main body 205, a mounting member 207, and a protective mat 208. The main body 205 is a shell-like structure that defines a toilet space 201. The mounting member 207 is located within the toilet space 201 and is used to mount the protective mat 208. The protective mat 208 is located within the toilet space 201 and is fixed to the mounting member 207 in a manner that it is laid within the toilet space 201. The protective mat 208 is filled with granules 209 (e.g., cat litter) for agglomerating pet excrement. When a pet enters the toilet space 201, it typically squats on the granules 209 filled on the protective mat 208 to defecate. After defecation, the pet's excrement agglomerates with these granules 209 into a clump.

[0030] The main body 205 can be integrally molded from plastic material, for example, by injection molding. The main body 205 has a bottom wall portion 210 and side wall portions 211 surrounding the bottom wall portion 210, which together define the toilet space 201. A first entrance / exit 202 allowing pets to enter and exit is formed, for example, in the side wall portion 211, and more specifically, on the side opposite to the bottom wall portion 210. The angle between the cross-section of the first entrance / exit 202 and the plane of the bottom wall portion 210 is, for example, in the range of 30° to 60°, thereby facilitating pets to enter and exit through the first entrance / exit 202 and into the toilet space 201. Although the size of the opening of the first entrance / exit 202 is not particularly limited, for the convenience of pets, the opening of the first entrance / exit 202 is, for example, shaped such that, from a top-down view, the bottom wall portion 210 is fully exposed within the range visible from above the first entrance / exit 202.

[0031] Main reference Figure 3 The mounting member 207 is fixed to the inner surface 211a of the side wall portion 211. The fixing method of the mounting member 207 is not particularly limited; for example, the mounting member 207 can be fixed to the inner surface 211a of the side wall portion 211 by various methods such as screw locking or snap-fit ​​fasteners. From a top view, the mounting member 207 is ring-shaped, and it is installed around the circumference of the side wall portion 211 onto the inner surface 211a of the side wall portion 211. For ease of explanation, it is assumed that the mounting member 207 is placed flat on a plane (e.g., as shown in the attached diagram). Figure 2 In a plane consisting of the front-back direction and the left-right direction, the mounting member 207 is viewed from a top-down perspective (e.g., vertical direction), with the outer side of the annular portion of the mounting member 207 as the radial direction (i.e.,...). Figure 2 The outer side of the mounting member 207 (in the front-back direction) is used as the inner side of the annular portion of the mounting member 207 as the radial inner side of the mounting member 207, in a direction perpendicular to the plane (i.e. Figure 2The vertical direction in the diagram is used as the axial direction of the mounting member 207. Furthermore, since the mounting member 207 is generally annular, for ease of explanation, the shape of the cross-section of the mounting member 207 will be used to describe each part of the mounting member 207.

[0032] The mounting member 207 includes an arched portion 212, a first extension 213, and a second extension 214. The arched portion 212 is formed at the center of the mounting member 207 in the axial (vertical) direction and arches inward toward the radial (front-rear) direction of the mounting member 207. One end of the first extension 213 is smoothly connected to the arched portion 212, and the other end extends relative to the arched portion 212 toward the axial direction of the mounting member 207 and toward the radially outward direction of the mounting member 207 (i.e., as shown, the first extension 213 extends upward and rearward simultaneously). The second extension 214 is located on the other side of the arched portion 212 (i.e., the lower side in the figure) relative to the first extension 213. One end of the second extension 214 is smoothly connected to the arched portion 212, and the other end extends on the opposite side of the arched portion 212 toward the mounting member 207 in the axial direction and toward the radially outward side of the mounting member 207 (i.e., as shown, the second extension 214 extends downward and backward at the same time).

[0033] With the mounting member 207 installed on the side wall portion 211, a receiving portion 215 is formed between the arched portion 212 and the side wall portion 211; the first extension portion 213 is located on the opposite side of the arched portion 212 and the bottom wall portion 210 (i.e., the upper side in the figure), and the other end of the first extension portion 213 is sealed with the inner surface 211a of the side wall portion 211 (for example, the end of the first extension portion 213 is attached to the inner surface 211a of the side wall portion 211); the second extension portion 214 is located on the same side of the arched portion 212 and the bottom wall portion 210 (i.e., the lower side in the figure).

[0034] The protective pad 208 has a pad portion 216 and a mounting portion 217. The pad portion 216 is opposite to the bottom wall portion 210 and the side wall portion 211 of the main body 205, so that the pad portion 216 is laid in the toilet space 201. The mounting portion 217 is formed around the edge of the pad portion 216, and the thickness of the mounting portion 217 is greater than the thickness of the pad portion 216. In the installed state of the protective pad 208, the mounting portion 217 is received in the receiving portion 215, and the protective pad 208 is pressed down by the other end of the second extension portion 214.

[0035] Main reference Figure 4 as well as Figure 5In the compartment 204 of this embodiment, the pad portion 216 of the protective pad 208 is laid within the toilet space 201 defined by the bottom wall portion 210 and the side wall portion 211 of the main body 205, and is pressed down from above by the other end of the second extension portion 214 of the mounting member 207. During normal use of the compartment 204, the protective pad 208 is filled with particles 209. When the particles 209 and pet excrement clump together and need to be cleaned, the main body 205 is rotated (e.g., clockwise), causing the first inlet / outlet 202 of the main body 205 to rotate from one side (e.g., the front side) to the other side (e.g., the rear side), and gradually downwards. As the first inlet / outlet 202 gradually moves downwards, the clump of particles 209 falls from the protective pad 208 across the mounting member 207 and from the first inlet / outlet 202.

[0036] In the compartment 204 of the embodiment, when cleaning pet excrement, i.e., when clumps of particles 209 fall across the mounting member 207 from the first inlet 202, it is possible to prevent them from getting stuck during the fall, thereby improving the smoothness of the excrement's fall. Specifically, during the fall of clumps of particles 209, these particles 209 are prone to getting stuck at the transition point between the mounting member 207 and the protective pad 208, i.e., at the location of the second extension 214 of the mounting member 207. In particular, when the total number of particles 209 is relatively small (e.g., just enough to cover the number of mounting members 207), clumps of particles 209 are more likely to get stuck at the transition point between the mounting member 207 and the protective pad 208. In the compartment 204 of the embodiment, when installing the protective pad 208, an arched portion 212 is formed, and the mounting portion 217 of the protective pad 208 is accommodated in a receiving portion 215 formed by the arched portion 212 and the side wall portion 211, thereby enabling the installation of the protective pad 208. Furthermore, a second extension 214 is formed in the mounting member 207, with one end smoothly connected to the arched portion 212, and the other end extending axially toward the mounting member 207 relative to the arched portion 212 and radially outward toward the mounting member 207. This second extension 214, when the mounting member 207 is installed on the side wall portion 211, is formed relative to the side wall portion 211 such that it extends from the arched portion 212 toward the bottom wall portion 210 while simultaneously extending toward the inner surface 211a of the side wall portion 211, thereby pressing down on the protective pad 208.

[0037] Thus, while the mounting member 207 presses down on the protective pad 208, a smooth guide surface 218 is formed on the side facing the bottom wall portion 210 via the second extension 214. When the particles 209 cross the mounting member 207, the particles 209 in contact with the mounting member 207 slide along the second extension 214 and fall along the first extension 213 after crossing the arch portion 212 (highest point). Furthermore, since the second extension 214 extends toward the inner surface 211a of the side wall portion 211, thereby pressing down on the protective pad 208, the gap between the other end (end) of the second extension 214 and the protective pad 208 is very small (much smaller than the size of the clump of particles 209). Therefore, it is possible to prevent these clumps of particles 209 from getting stuck, thereby further improving the smoothness of the excrement falling.

[0038] Mounting component 207 can be integrally molded from plastic material by injection molding, for example. As the plastic material, materials that are primarily rigid but also possess elasticity within a certain deformation range (i.e., exhibiting a certain degree of toughness and recoverable deformation ability) and are corrosion-resistant can be used. Examples include: polycarbonate (PC), thermoplastic polyurethane (TPU), polyamide (nylon), polypropylene (PP), ABS (acrylonitrile-butadiene-styrene copolymer), POM (polyoxymethylene), etc. Since mounting component 207 is formed in a ring shape, the arched portion 212, the first extension 213, and the second extension 214 are also formed in a ring shape. Furthermore, it can be understood that when mounting component 207 is radially cut at any location, the cross-sectional shapes of the arched portion 212, the first extension 213, and the second extension 214 are approximately the same, unless otherwise stated.

[0039] Reference Figure 3The mounting member 207 may also have a plurality of mounting supports 219 for locking the mounting member 207 onto the side wall portion 211 of the main body 205. The plurality of mounting supports 219 are spaced circumferentially along the side of the mounting member 207 opposite to the inner surface 211a of the side wall portion 211. The mounting supports 219 may have threaded holes (not shown), and correspondingly, the side wall portion 211 has through countersunk holes (not shown). Screws (not shown) pass through the side wall portion 211 from the outside and connect to the threaded holes on the mounting supports 219, thereby mounting the mounting member 207 onto the inner surface 211a of the side wall portion 211 via the mounting supports 219. Furthermore, the mounting supports 219 are formed on the side near the first extension 213. Since the mounting member 207 forms a receiving portion 215 for accommodating the mounting portion 217 of the protective pad 208 through the arch 212, by forming the mounting post 219 on the side close to the first extension 213, the mounting post 219 can at least partially avoid the receiving portion 215, thereby ensuring that the receiving portion 215 has sufficient space to accommodate the mounting portion 217 of the protective pad 208.

[0040] The mounting portion 217 of the protective pad 208 is accommodated in the receiving portion 215, and the other end (i.e., the end) of the second extension 214 of the mounting member 207 presses against the portion of the pad portion 216 of the protective pad 208 adjacent to the mounting portion 217. Since the thickness of the mounting portion 217 is greater than the thickness of the pad portion 216, by accommodating the mounting portion 217 in the receiving portion 215 and having the portion of the pad portion 216 adjacent to the mounting portion 217 locked by the end of the second extension 214, it is possible to prevent the protective pad 208 from being pressed down by the particulate matter 209 and falling off the mounting member 207.

[0041] It should be noted that although the end of the second extension 214 presses against the portion of the pad 216 adjacent to the mounting portion 217, "presses against" here should be understood as the end of the second extension 214 at least partially pressing against the inner surface 211a of the side wall portion 211, rather than requiring the end of the second extension 214 to tightly fit the pad 216 against the inner surface 211a of the side wall portion 211. This is because both the main body 205 of the compartment 204 and the mounting component 207 are injection molded from injection molding material. From the perspective of controlling assembly precision, it is difficult to ensure that the installation positions of the main body 205 of the compartment 204 and the mounting component 207 are consistent along the circumferential direction. However, as long as the end of the second extension 214 is formed to at least partially press the pad portion 216 against the inner surface 211a of the sidewall portion 211, the gap between the end of the second extension 214 and the protective pad 208 can be reduced, thereby preventing clump-shaped particles 209 from getting stuck in the gap between the end of the second extension 214 and the protective pad 208. Furthermore, since there may be wrinkles in the portion of the pad portion 216 of the protective pad 208 adjacent to the mounting portion 217, as long as the end of the second extension 214 is formed to at least partially press the pad portion 216 against the inner surface 211a of the sidewall portion 211, these wrinkles can be reduced to a certain extent, thereby also preventing clump-shaped particles 209 from getting stuck in these wrinkles of the pad portion 216 of the protective pad 208.

[0042] Furthermore, a mounting gap 230 may be provided between the other end (i.e., the end portion) of the second extension 214 and the inner surface 211a of the sidewall portion 211. Correspondingly, the mounting portion 217 of the protective pad 208 is formed to be compressible and deformable along the thickness direction, thereby entering the receiving portion 215 or being pulled out from the receiving portion 215 via the mounting gap 230. In this way, it is convenient to assemble and disassemble the protective pad 208. From the perspective of preventing the end portion of the second extension 214 from failing to press against the pad portion 216 of the protective pad 208, resulting in a large gap between the end portion of the second extension 214 and the pad portion 216, the width of the mounting gap 230 (i.e., the straight-line distance from the part closest to the inner surface 211a at the end portion of the second extension 214 to the inner surface 211a) can be 8 mm or less when the second extension 215 is not subjected to external force. In addition, from the perspective of facilitating the assembly and disassembly of the protective pad 208, the width of the mounting gap 230 is, for example, 4 mm or more. Preferably, the width of the mounting gap 230 can be 6 mm or less and 2 mm or more. In addition, since the mounting member 207 is a member with elasticity (i.e., an elastic element), when the second extension 214 of the mounting member 207 is subjected to a force that moves the end of the second extension 214 away from the inner surface 211a of the side wall portion 211, the second extension 214 undergoes a certain elastic deformation, thereby increasing the mounting gap 230.

[0043] Continue to refer to Figure 3 and supplementary reference Figure 1 as well as Figure 2 The protective pad 208 is used to prevent pet excrement from penetrating the side wall portion 211 and / or bottom wall portion 210 of the main body 205. In addition, the protective pad 208 may also have other functions such as anti-slip. The protective pad 208 can be detached or installed relative to the mounting member 207. As described above, the protective pad 208 has a pad portion 216 and a mounting portion 217, and the thickness of the mounting portion 217 is greater than the thickness of the pad portion 216. The pad portion 216 of the protective pad 208 can be composed of a single sheet or multiple sheets (not shown in the figures). For example, the pad portion 216 may include a surface layer sheet, an intermediate layer sheet, and a bottom layer sheet. The materials of these different layers can be appropriately selected; for example, the surface layer sheet can use materials such as TPE / TPR (thermoplastic elastomer), silicone, PVC (polyvinyl chloride); the intermediate layer sheet can use materials such as PEVA (polyethylene-vinyl acetate), TPU (thermoplastic polyurethane), rubber; and the bottom layer sheet can use a suitable anti-slip film. The mounting portion 217 is formed at the edge of the pad portion 216. The mounting portion 217 is deformable relative to the pad portion 216 but possesses a certain degree of rigidity. For example, the mounting portion 217 may include a mounting core 211 and a sleeve 212 that wraps around the mounting core 211. The sleeve 212 is wrapped around the perimeter of the pad portion 216 and fixed by various methods such as needle and thread sewing or heat fusion. The mounting core 211 can be made of elastic materials such as steel wire rope, nickel-titanium alloy, glass fiber, or nylon, while the sleeve 212 can be made of materials such as thermoplastic elastomer, silicone, rubber, polyurethane, polyvinyl chloride (PVC), nylon, or polytetrafluoroethylene. Therefore, when the mounting portion 217 is compressed, it can be compressed and deformed along the thickness direction (i.e., radially).

[0044] The thickness (i.e., radial thickness) of the mounting portion 217 of the protective pad 208 is greater than the width of the mounting gap 230, and it is housed in the receiving portion 215 in a state of compression deformation along the thickness direction. Therefore, the mounting portion 217 of the protective pad 208 can fully fill the receiving portion 215, thereby suppressing the presence of particulate matter 209 in the receiving portion 215. Furthermore, when the mounting portion 217 is compressed along the thickness direction, the maximum thickness of the mounting portion 217 along this compression direction is less than the width of the mounting gap 230.

[0045] The protective pad 208 can be installed to or removed from the mounting member 207 via the mounting gap 230. For example, when installing the protective pad 208, the protective pad 208 is first placed in the toilet space 201, and the pad portion 216 is laid with the bottom wall portion 210 and the side wall portion 211. Then, the mounting portion 217 is aligned with the mounting gap 230 formed between the end of the second extension portion 214 and the inner side surface 211a of the side wall portion 211. By pressing the mounting portion 217 toward the mounting gap 230, the mounting portion 217 is inserted into the receiving portion 215 through the mounting gap 230.

[0046] When removing the protective pad 208, grasp the pad portion 216 of the protective pad 208 and pull it towards the bottom wall portion 210. The mounting portion 217 is compressed and deformed, and is pulled out from the receiving portion 215 through the mounting gap 230. Since the mounting member 207 is an elastic member, when the mounting portion 217 is pulled out from the receiving portion 215, the second extension portion 214 is squeezed by the mounting portion 217 and elastically deforms in the direction that increases the mounting gap 230. Therefore, even when the mounting gap 230 is very small in the unloaded state, the mounting portion 217 can be pulled out from the receiving portion 215.

[0047] In the compartment 204 of the embodiment, the second extension 214 of the mounting member 207 extends toward the inner side 211a of the side wall portion 211, thereby pressing down on the protective pad 208. In this case, the gap between the end of the second extension 214 and the protective pad 208 is very small (much smaller than the size of the clump of particles 209), so it is possible to prevent these clumps of particles 209 from getting stuck and improve the smoothness of the excrement falling.

[0048] In the compartment 204 of the embodiment, the protective pad 208 can be reliably fixed by pressing the end of the second extension 214 against the portion of the pad 216 adjacent to the mounting portion 217. In this way, since the mounting portion 217 is accommodated in the receiving portion 215 and the thickness of the mounting portion 217 is greater than the thickness of the pad 216, it is possible to prevent the pad 216 from falling off relative to the mounting member 207.

[0049] In the compartment 204 of the embodiment, by having an installation gap 230 between the end of the second extension 214 and the inner side surface 211a of the side wall 211, and by forming the mounting portion 217 to be compressible and deformable in the thickness direction, the protective pad 208 can be easily removed or installed by entering the receiving portion 215 or being pulled out of the receiving portion 215 through the installation gap 230.

[0050] Furthermore, by making the width of the mounting gap 230 4 mm or more and 8 mm or less, it is possible to further suppress ordinary particulate matter 209 (i.e., non-clumped particulate matter 209) from entering the receiving portion 215 through the mounting gap 230.

[0051] Furthermore, by making the mounting member 207 an elastic element, when the mounting portion 217 is pulled out from the receiving portion 215, the second extension 214 is squeezed by the mounting portion 217 and elastically deforms in the direction that increases the mounting gap 230, thereby further reducing the width of the mounting gap 230. For example, since the second extension 214 can elastically deform and the mounting portion 217 can be compressed and deformed, even if the mounting gap 230 is set very small (e.g., 2 mm), the mounting gap 230 can be increased by elastically deforming the second extension 214, thereby allowing the protective pad 208 to be removed.

[0052] Furthermore, since the installation gap 230 can be set very small, it is also possible to achieve that when the protective pad 208 is installed, the end of the second extension 214 presses against the pad portion 216 of the protective pad 208 in a manner that is close to the pad portion 216 of the protective pad 208.

[0053] In the compartment 204 of the embodiment, by storing the mounting part 217 in the receiving part 215 in a state of being compressed and deformed along the thickness direction, the gap in the receiving part 215 can be reduced, and the ordinary particulate matter 209 can be suppressed from remaining in the receiving part 215.

[0054] Furthermore, while the above embodiments illustrate examples of how the protective pad 208 can be installed onto or removed from the mounting member 207 via the mounting gap 230, the embodiments are not limited to this. For example, when the mounting member 207 is fastened to the inner side 211a of the side wall portion 211 by a snap fastener, the mounting member 207 can also tightly press the protective pad 208. When removing the protective pad 208, the mounting member 207 is first removed, and then the protective pad 208 is taken off.

[0055] Reference Figure 6 Furthermore, in the above embodiment, a zipper portion 220 may be formed between the pad portion 216 and the mounting portion 217 of the protective pad 208, allowing the pad portion 216 to be installed or detached from the mounting portion 217 via the zipper portion 220. When the protective pad 208 needs to be removed for cleaning, only the pad portion 216 of the protective pad 208 is cleaned, while the mounting portion 217 remains fixed in place by the mounting member 207. In this manner, the mounting member 207 can also tightly press against the mounting portion 217 of the protective pad 208.

[0056] Reference Figure 3 as well as Figure 6Furthermore, while the above embodiment illustrates an example where the end of the first extension 213 abuts against the inner surface 211a of the side wall 211, thereby sealing the other end of the first extension 213 with the inner surface 211a of the side wall 211, this is not a limitation. For example, the compartment 204 may also include an annular sealing strip 221 sandwiched between the other end of the first extension 213 and the inner surface 211a of the side wall 211, thereby sealing the other end of the first extension 213 with the inner surface 211a of the side wall 211. In this way, it is possible to prevent liquid pet excrement from flowing into the surface of the side wall 211 or bottom wall 210 of the main body 205 through the gap between the end of the first extension 213 and the inner surface 211a of the side wall 211, thus preventing contamination of the main body 205 of the compartment 204.

[0057] Furthermore, to prevent particles 209 from accidentally passing through the protective pad 208 and / or mounting member 207 and directly remaining on the bottom wall 210 and / or side wall 211 of the main body 205, the main body 205 may have sand-draining holes 222 formed in the bottom wall 210. The shape or number of sand-draining holes 222 is not limited; for example, they can be various shapes such as annular holes or waist-shaped holes. The sand-draining holes 222 are directly connected to the second inlet and outlet 206 of the outer casing 203. This allows for very convenient cleaning of particles 209 and the like that that may directly remain on the inner surface 211a of the bottom wall 210 and / or side wall 211 of the main body 205.

[0058] Continue to refer to Figure 1 as well as Figure 2 The following describes the other structures of compartment 204.

[0059] The chamber 204 may also include a screen 223 and a barrier 224 for separating clump-shaped particles 209 from ordinary particles 209.

[0060] A blocking member 224 is located within the toilet space 201 and is disposed on the side wall portion 211 along the rotation direction of the main body 205. A return space 225 towards the bottom wall portion 210 is formed between the blocking member 224 and the side wall portion 211. Specifically, one end of the blocking member 224 is connected to the edge of the first inlet / outlet 202 of the main body 205 and is fitted against the side wall portion 211. The other end of the blocking member 224 extends toward the bottom wall portion 210 and is raised relative to the inner surface 211a of the side wall portion 211, thereby forming a return space 225 towards the bottom wall portion 210 between the blocking member 224 and the side wall portion 211.

[0061] A screen 223, located within the toilet space 201, is mounted on the side wall portion 211 and extends across the blocking member 224 in the width direction (left-right direction in the drawing). One end of the screen 223 is connected to the blocking member 224 and has an overlapping portion with it, while the other end of the screen 223 extends toward the mounting member 207. Specifically, one end of the screen 223 is fixed to the side wall portion 211 and connected to one end of the blocking member 224. There is an overlapping portion between one end of the screen 223 and the other end of the blocking member 224. The other end of the screen 223 extends substantially to the position of the first extension 213 of the mounting member 207, and can abut against the side wall portion 211 and be supported by it. Furthermore, the size and type of the screen openings of the screen 223 are not particularly limited and can be appropriately set according to the size and type of the particles 209. The size of the screen 223 is such that it allows ordinary particles 209 to pass through while restricting the passage of clump-shaped particles 209.

[0062] When the main body 205 is rotated, for example clockwise, the first inlet / outlet 202 rotates from one side (e.g., the front) to the other side (e.g., the rear) and gradually downwards. Particles 209 cross the mounting member 207 from the protective pad 208 and fall onto the screen 223. Ordinary particles 209 pass through the screen holes of the screen 223 and fall into the return space 225. Clumps of particles 209, unable to pass through the screen holes of the screen 223, continue to fall onto the blocking member 224 and then along the blocking member 224 into the collection space 102. After cleaning, the main body 205 is rotated counterclockwise. At this time, the first inlet / outlet 202 rotates from below to above, and the ordinary particles 209 collected in the return space 225 pass through the screen holes of the screen 223 and return to the protective pad 208.

[0063] Thus, the removal of clump-shaped particles 209 is completed.

[0064] Continue to refer to Figure 7 The following is a brief description of the structure that makes compartment 204 rotate.

[0065] For example, the outer casing 203 may be provided with a support assembly 226 for supporting the main body 205 of the compartment 204, which acts as a bearing seat. The type of support assembly 226 is not particularly limited, and may include side support rollers on both sides of the main body 205 of the compartment 204 in the width direction (i.e., the left-right direction in the figure). Correspondingly, support shafts 227 may be formed on both sides of the main body 205 of the compartment 204 in the width direction, and the main body 205 of the compartment 204 is supported on the support rollers by the support shafts 227. The support shafts 227 are connected to a motor 229 via, for example, a transmission mechanism 228 (e.g., a gear transmission mechanism), so that when the motor 229 is working, it drives the support shafts 227 of the main body 205 to rotate around the support assembly 226, which acts as a bearing seat, thereby realizing the rotation of the main body 205.

[0066] Furthermore, although the above embodiment describes the pet toilet compartment 204 as a rotating component within the pet toilet device and driven by the motor 229, it is not limited to this. The pet toilet compartment 204 could also be a stand-alone device; for example, the compartment 204 could be used as a simple litter box. In this case, when cleaning excrement, the pet owner could manually operate the compartment 204, causing the first inlet / outlet 202 of the compartment 204 to face downwards, thereby cleaning the excrement.

[0067] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
