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 places where pets are kept, pet toileting devices are provided to facilitate the pets' use of the litter box. Taking a cat toileting device (sometimes referred to as a "cat litter box" for ease of explanation) as an example, a typical cat litter box usually has a compartment for the cat to use (sometimes called a "litter chamber" for ease of explanation). To prevent cat excrement from contaminating the main body of the compartment, the compartment is usually lined with excrement-aggregating granules (such as cat litter). After the cat defecates in the compartment, the excrement combines with the cat litter to form clumps.

[0003] When cleaning the inside of the litter box, it's necessary to separate the clumps of litter mixed with cat excrement from the clean, granular litter. The clumps should be removed while the clean, granular litter remains in the litter box. In typical litter boxes, this separation and removal of clumps is usually done manually by the cat's owner.

[0004] Because litter box compartments often have a strong odor from excrement, some manufacturers have proposed a method to reduce the workload for cat owners. This involves rotating the compartment and using a sieve to separate clumps of litter from clean, granular litter, thus removing the clumps. However, in this method, the clumps are temporarily stored on the sieve, requiring the cat owner to manually remove the sieve. This still forces the cat owner to endure the unpleasant odor while cleaning the litter box. Utility Model Content

[0022] 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.

[0023] Reference Figures 1 to 8 and mainly refer to Figure 7 , Figure 8 Pet 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 is supported on a floor, table, or any location where it is easy for the pet to enter and exit. 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.

[0024] 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.

[0025] 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 illustrative purposes, 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. Furthermore, in Figure 2 as well as Figure 5 In the diagram, to clearly illustrate the connection between the screen 223 and the side wall 211, the first fastener 240 and the second fastener 245 are represented by dashed lines. Figure 6 In order to facilitate the illustration of the connection relationship between the screen 223 and the side wall 211, only the part of the screen 223 with the first fastener 240 and the second fastener 245 are shown.

[0026] The chamber 204 of the embodiment includes a main body 205, a blocking member 224 for separating clump-shaped particles 209, and a screen 223. The main body 205 has a bottom wall portion 210 and a side wall portion 211 surrounding the bottom wall portion 210, which together define the toilet space 201. A first inlet / outlet 202 is formed on the side wall portion 211. The blocking member 224 and the screen 223 are both located within the toilet space 201. The blocking member 224 is disposed on the side wall portion 211 along the rotation direction of the main body 205 (in the figures, the rotation direction in a plane formed by the front-back direction and the up-down direction), and a return space 225 is formed between the blocking member 224 and the inner surface 211a of the side wall portion 211, facing the bottom wall portion 210. The screen 223 is spaced between the bottom wall portion 210 and the return space 225 along the rotation direction of the main body 205.

[0027] The compartment 204 of the embodiment is capable of automatically removing clumps of particles 209 containing pet excrement from the compartment 204 while simultaneously separating such clumps. Specifically, for example, see... Figure 3 When the main body 205 is rotated clockwise, for example in a plane formed by the front-back direction and the up-down direction, the first inlet and outlet 202 rotates from one side (e.g., the front side) to the other side (e.g., the rear side) and gradually moves downwards. The particles 209 fall onto the screen 223. At this time, ordinary particles 209 (i.e., particles 209 that are not combined with pet excrement) pass through the screen holes 231 of the screen 223 and fall into the return space 225. The clump-shaped particles 209 cannot pass through the screen holes 231 of the screen 223 because their cross-section is larger than the size of the screen holes 231 of the screen 223, and continue to fall onto the blocking member 224, and then fall into the collection space 102 along the blocking member 224. After cleaning is completed, the main body 205 is rotated counterclockwise. At this time, the first inlet / outlet 202 rotates from bottom to top, and the ordinary particles 209 collected in the return space 225 pass through the sieve holes 231 of the screen 223 and return to the bottom wall 210. Thus, while separating the clumps of particles 209, these clumps of particles 209 are automatically cleaned from the chamber 204.

[0028] Continue to refer to Figure 1 as well as Figure 2 The first entrance / exit 202 of the main body 205, which allows pets to enter and exit, can be formed, for example, on the side wall 211 opposite to the bottom wall 210. The angle between the cross-section of the first entrance / exit 202 and the plane of the bottom wall 210 is, for example, between 30° and 60°, thereby facilitating the pet's entry and exit from 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 the pet, the size of the opening of the first entrance / exit 202 is, for example, formed such that, from a top view, the bottom wall 210 is fully exposed within the range visible from above the first entrance / exit 202. The main body 205 is mounted to the outer casing 203 in a manner that allows the first entrance / exit 202 to rotate downwards. The toilet space 201 of the main body 205 may also be provided with a mounting member 207 and a protective pad 208, the protective pad 208 being fixed to the mounting member 207 by being laid within the toilet space 201. The protective pad 208 is filled with granules 209 (such as cat litter) to collect pet excrement. When a pet enters the toilet space 201, it usually squats on the granules 209 filled on the protective pad 208 to relieve itself. After using the toilet, the pet's excrement will clump together with these granules 209.

[0029] Main reference Figure 1 , Figure 2 as well as Figure 4 The blocking member 224 is installed on the inner side 211a of the side wall portion 211, and generally spans the width direction of the toilet space 201 (see attached). Figure 1 The center (or center) refers to the left-right direction, which can also be understood as the direction parallel to the rotation center of the toilet space 201 and the compartment 204. The blocking member 224 has a first end portion 232 at one end and a second end portion 233 at the other end. The first end portion 232 and the second end portion 233 are opposite each other and form a guide portion 234 for guiding the falling particles 209. The first end portion 232 is connected to the side wall portion 211 located on one side of the first inlet / outlet 202, and the connection position between the first end portion 232 and the side wall portion 211 is sealed. The second end portion 233 faces the bottom wall portion 210 and is raised relative to the inner surface 211a of the side wall portion 211, thereby forming a reflux space 225 between the blocking member 224 and the inner surface 211a of the side wall portion 211.

[0030] The first end 232 of the blocking member 224 has a mounting wall 235, through which the first end 232 is mounted to the edge of the first inlet / outlet 202 of the main body 205. The mounting wall 235 is mounted to the edge of the first inlet / outlet 202 of the main body 205, for example, by a threaded connection. When the blocking member 224 is mounted to the side wall portion 211, the mounting wall 235 of the blocking member 224 abuts against and protrudes from the inner surface 211a of the side wall portion 211, thereby sealing the position of the first end 232 and the inner surface 211a of the side wall portion 211. The position of the mounting wall 235 becomes the end point of the return space 225. That is, when ordinary particles 209 fall into the return space 225 through the screen 223, as the main body 205 rotates further clockwise, these particles 209 are finally blocked by the mounting wall 235 (the side facing the return space 225) and the guide part 234 (the side facing the return space 225) in the return space 225.

[0031] The second end 233 of the blocking member 224 is formed such that the distance between it and the inner surface 211a of the side wall 211 gradually increases as it moves toward the bottom wall 210. Furthermore, the distance by which the second end 233 is raised relative to the inner surface 211a is not particularly limited, as long as the second end 233 does not coincide with the bottom wall 210 when viewed from a top viewpoint, provided that the bottom wall 210 is positioned directly below the main body 205. The guide portion 234 between the second end 233 and the first end 232 is curved, and the curvature of the guide portion 234 is slightly greater than the curvature of the inner surface 211a of the side wall 211 at that position.

[0032] The width direction of the blocking member 224 (i.e., the attached) Figure 1In the left-right direction (unless otherwise specified, the description of the width direction of the blocking member 224 refers to the direction consistent with the width direction of the toilet space 201 when the blocking member 224 is installed in the toilet space 201), roll-up portions 236 are formed on both sides, and the roll-up portions 236 are rolled up relative to the guide portion 234. The roll-up portions 236 are respectively installed on both sides of the side wall portion 211 in the width direction by abutting against the side wall portion 211. The roll-up portions 236 can also be installed on both sides of the side wall portion 211 in the width direction by means of threaded connection, for example. Thus, by forming the roll-up portions 236 on both sides of the blocking member 224 in the width direction, the blocking member 224 is made to be roughly "basket-shaped" in general. By forming the blocking member 224 in this way, the guide portion 234 of the blocking member 224 can extend arcuately from the first end 232 toward the second end 233, and also roll up arcuately to both sides in the width direction. Thus, the guide portion 234 can cause the particles 209 to fall from the second end 233 toward the first end 232 while being gathered toward the center in the width direction by the two roll-up portions 236.

[0033] Main reference Figure 1 , Figure 2 as well as Figure 4 The screen 223 is approximately along the width direction of the return space 225 (i.e., Figure 1 The screen 223 spans the return space 225 in a left-right direction. The screen 223 has a third end 237 at one end and a fourth end 238 at the other end. The third end 237 and the fourth end 238 are opposite to each other. The third end 237 is disposed to the second end 233 of the sidewall portion 211 or the blocking member 224, and the third end 237 and the second end 233 of the blocking member 224 are mated. The fourth end 238 extends circumferentially along the portion of the sidewall portion 211 located in the return space 225.

[0034] The screen 223 can be integrally molded from a plastic material using injection molding. The plastic material can be primarily rigid, but also possesses elasticity (i.e., exhibiting a certain degree of toughness and recoverable deformation capacity) within a certain deformation range and is corrosion-resistant. Examples include: polycarbonate (PC), thermoplastic polyurethane (TPU), polyamide (nylon), polypropylene (PP), ABS (acrylonitrile-butadiene-styrene copolymer), and POM (polyoxymethylene). In other words, the screen 223 is an elastic component as a whole. When the screening surface 223a of the screen 223 is subjected to high pressure, the screen 223 can elastically deform, and after the pressure is removed, the surface of the screen 223 can return to its original shape.

[0035] The third end 237 and the fourth end 238 of the screen 223 can together form the four edges of the screen 223. The third end 237 extends in a roughly straight line in the left-right direction. The fourth end 238 is arc-shaped, with one end extending to both ends of the third end 237 in the left and right directions. Thus, the screen 223 is generally formed in a fan shape. In addition, the screening surface 223a of the screen 223, which forms the screen holes 231 and is used to screen the particles 209, is generally arc-shaped, and the screen 223 is installed on the side wall 211 with the protruding arc surface of the screening surface 223a facing the bottom wall 210. The screening surface 223a of the screen 223 has a plurality of screen holes 231, and the shape of the screen holes 231 is not particularly limited, but can be determined according to the shape of the particles 209. For example, when the particles 209 are spherical, the shape of the sieve aperture 231 can be circular; when the particles 209 are elongated, the shape of the sieve aperture 231 can be elongated, etc.

[0036] The screen 223 is detachably mounted on both sides of the sidewall portion 211 in the width direction of the return space 225. Furthermore, when the bottom wall portion 210 is positioned directly below the main body 205, the screen 223 does not coincide with the bottom wall portion 210 when viewed from a top view. A third end portion 237 is mounted on the sidewall portion 211 in such a way that the screen 223 can swing within a predetermined angle range. The swing angle of the screen 223 is set such that, at least when the first inlet / outlet 202 of the main body 205 is facing downwards, the fourth end portion 238 can abut against the sidewall portion 211. With the fourth end portion 238 abutting against the sidewall portion 211, the angle at which the screen swings downwards (counterclockwise in the accompanying drawings) is limited. Specifically, the two ends of the third end 237 of the screen 223 in the left and right directions (i.e., the width direction of the screen 223; unless otherwise specified, the description of the width direction of the screen 223 refers to the direction consistent with the width direction of the screen 223 when the screen 223 is installed in the toilet space 201) are respectively hinged to the two sides of the side wall portion 211 in the left and right directions, so that the screen 223 can swing in the plane formed by the front-back direction and the left-right direction.

[0037] When the main body 205 is in its initial position, i.e., the bottom wall portion 210 is directly below the main body 205, the screen 223 swings clockwise to its restricted position due to gravity. At this time, the fourth end 238 of the screen 223 slightly moves away from the side wall portion 211 (see reference). Figure 2 When the main body 205 rotates clockwise (for example, rotates to the position where the first inlet and outlet 202 of the main body 205 faces downward), the screen 223 swings counterclockwise to the position where the fourth end 238 abuts against the side wall 211 due to gravity or the thrust generated by the flow of particles 209 (see reference). Figure 3In other words, when the main body 205 rotates clockwise or counterclockwise, the screen 223 can also swing within a specified angle range. The specified swing angle range of the screen 223 can be 5° or more and 20° or less. For example, taking the position of the fourth end 238 of the screen 223 abutting the side wall portion 211 as a reference, the screen 223 can swing clockwise around the hinge position by an angle of 5° or more and 20° or less; or, it can be 5° or more and 15° or less.

[0038] A blocking strip 239 is formed at the third end 237 of the screen 223. The blocking strip 239 extends along the length of the third end 237 and substantially covers the entire third end 237 in the left-right direction. The cross-section of the blocking strip 239 is approximately L-shaped. The blocking strip 239 is formed to start from the lower end of the third end 237, extend downward, then bend and extend rearward. Thus, the blocking strip 239 protrudes from the third end 237.

[0039] Reference Figure 5 as well as Figure 6 On the left and right edges (i.e., both sides of the width of the screen 223) of the third end 237, the screen 223 has first fastening members 240. Each first fastening member 240 has a groove 241 with a latch 242 facing outwards from the third end 237. Furthermore, the groove 241 is open in the left and right directions. From a side view (i.e., a left-right view), the groove 241 is approximately elliptical. For example, the groove 241 is elliptical in shape such that the latch 242 is narrowed relative to the middle of the groove 241, the middle of the groove 241 gradually expands outwards relative to the latch 242, and the bottom of the groove 241 gradually narrows relative to the middle. The portion of the first fastening member 240 near the latch 242 is suspended relative to the third end 237, allowing the latch 242 of the first fastening member 240 to easily expand outwards and enlarge when compressed.

[0040] On the left and right edges of the third end 237 of the screen 223, relative to the inner side of the first fastener 240, two side plates 243 are formed, each extending downward relative to the third end 237. The two side plates 243 are parallel in the left and right direction. Furthermore, the two side plates 243 are connected to the bottom of the two first fasteners 240 near the slot 241 via connecting blocks 244. That is, the side plates 243 are integrally formed with the bottom of the first fasteners 240 near the slot 241 via connecting blocks 244. This strengthens the bottom of the slot 241.

[0041] On both sides of the sidewall portion 211 of the main body 205, located in the width direction (i.e., left-right direction) of the return space 225, second fasteners 245 are respectively provided. The installation method of the second fasteners 245 is not particularly limited; for example, they can be locked to the inner surfaces 211a on both sides of the sidewall portion 211 in the left-right direction by means of a threaded connection. The second fasteners 245 have protrusions 246 extending in the left-right direction, and the cross-sectional shape of the protrusions 246 is elliptical (rugby ball-shaped). More specifically, the cross-sectional shape of the protrusions 246 is approximately matched with the shape of the slot 241, and the diameter of the minor axis of the protrusions 246 is larger than the width of the latch 242 of the first fastener 240. A guide plate 247 is formed at the lower part of the second fasteners 245. The guide plate 247 is spaced from the protrusions 246 in the vertical direction and also extends in the left-right direction.

[0042] The screen 223 can be detachably installed on both sides of the side wall portion 211 in the width direction by the mutual engagement of the first fastener 240 and the second fastener 245. The lower portion of the latch 242 of the first fastener 240 is aligned with the gap between the protrusion 246 of the second fastener 245 and the guide plate 247, thereby causing the first fastener 240 to abut against the guide plate 247, completing the initial positioning. Then, the latch 242 of the first fastener 240 of the screen 223 is aligned with the protrusion 246 of the second fastener 245, and the screen 223 is pushed towards the protrusion 246, causing the latch 242 of the first fastener 240 to elastically deform and expand, thereby allowing the protrusion 246 to enter the slot 241. After the protrusion 246 enters the slot 241, the latch 242 of the first latch 240 resets, so that the slot 241 of the first latch 240 covers most of the protrusion 246 of the second latch 245, and the portion of the protrusion 246 facing the latch 242 is not covered. Furthermore, in the installed state of the screen 223, the two side plates 243 restrict the left-right position of the screen 223, preventing the protrusion 246 from falling out of the slot 241 in the left-right direction.

[0043] In this way, the screen 223 can be mounted on both sides of the side wall portion 211 in the left-right direction. With the screen 223 installed, the third end 237 of the screen 223 abuts against the blocking member 224 and generally spans the left-right direction of the side wall portion 211. The blocking strip 239 formed at the third end 237 of the screen 223 is located below the second end 233 of the blocking member 224, thus partially overlapping the screen 223 and the blocking member 224. The fourth end 238 of the screen 223 faces the portion of the side wall portion 211 adjacent to the bottom wall portion 210, and the shape of the edge of the fourth end 238 matches the circumferential shape of the portion of the side wall portion 211 located in the return space 225, that is, the fourth end 238 extends approximately circumferentially along the portion of the side wall portion 211 located in the return space 225.

[0044] Furthermore, since the cross-section of the protrusion 246 of the second fastener 245 is elliptical, and the shape of the slot 241 of the first fastener 240 matches the shape of the protrusion 246, and the portion of the protrusion 246 facing the latch 242 is not covered, therefore, in the state where the first fastener 240 and the second fastener 245 are fastened (hinged), although the screen 223 can swing relative to the side wall portion 211 as a whole, the angle of swing is limited.

[0045] In the compartment 204 of the embodiment, by providing a blocking member 224 in the toilet space 201 along the rotation direction of the main body 205 and forming a return space 225 between the side wall portion 211, and by providing a screen 223 along the rotation direction of the main body 205 between the return space 225 and the bottom wall portion 210, it is possible to automatically clean the clumps of particles 209 that are bound to pet excrement from the compartment 204 while separating them. For example, when the main body 205 is rotated clockwise and particles 209 fall onto the screen 223, ordinary particles 209 pass through the screen holes 231 of the screen 223 and fall into the return space 225. Clumps of particles 209, because their cross-section is larger than the size of the screen holes 231, cannot pass through the screen holes 231 and continue to fall, landing on the blocking member 224 and then falling along the guide portion 234 of the blocking member 224 into the collection space 102. When the main body 205 is rotated counterclockwise, the ordinary particles 209 collected in the return space 225 pass through the screen holes 231 of the screen 223 and return to the protective pad 208. Thus, while separating clumps of particles 209, these clumps of particles 209 are automatically removed from the chamber 204.

[0046] In the compartment 204 of the embodiment, when the blocking member 224 and the screen 223 are positioned at the bottom wall portion 210 directly below the main body 205, they do not coincide with the bottom wall portion 210 when viewed from a top view (see reference). Figure 1 , Figure 2 This ensures that the position of the barrier 224 and the screen 223 in the toilet space 201 does not affect the pet's entry, exit, or toilet use.

[0047] In the compartment 204 of the embodiment, roll-up portions 236 are formed on both sides of the width direction of the blocking member 224. The roll-up portions 236 roll up relative to the guide portion 234 and abut against the side wall portion 211, thereby enabling the particles 209 to gradually converge toward the center of the blocking member 224 in the left and right directions while falling, thus suppressing the disorderly falling of the particles 209.

[0048] In the compartment 204 of the embodiment, by providing the screen 223 to the side wall 211 in a manner that allows it to swing within a predetermined angle, it is possible to prevent particles 209 from getting stuck in the screen holes 231 of the screen 223. For example, when the main body 205 rotates clockwise, the screen 223 swings slightly counterclockwise (shakes) due to gravity, and the shaking of the screen 223 makes it easier for the particles 209 to fall off. Similarly, when the main body 205 rotates counterclockwise, the screen 223 shakes slightly clockwise due to gravity, making it easier for the particles 209 to fall off. Furthermore, if the main body 205 is repeatedly switched between clockwise and counterclockwise rotation, it is even easier for the particles 209 to fall off.

[0049] Furthermore, by ensuring that the fourth end 238 abuts against the side wall 211 at least when the first inlet / outlet 202 of the main body 205 is facing downwards (i.e., when cleaning clumps of particles 209), both the third end 237 and the fourth end 238 are supported, ensuring sufficient support for the screen 223. Additionally, since the first latching member 240 near the bottom of the slot 241, the side plate 243, and the connecting block 244 are integrally formed, the strength at that location is enhanced. This helps to prevent damage to the screen 223 at the location of the first latching member 240.

[0050] In addition, by bringing the fourth end 238 abutting against the side wall portion 211, the gap between the fourth end 238 of the screen 223 and the side wall portion 211 can be reduced, thus suppressing the clump-shaped particles 209 from falling into the return space 225 through the gap.

[0051] Furthermore, by making the swing angle of the screen 223 between 5° and 20°, it is possible to ensure that the screen 223 is a certain distance away from the inner side surface 211a of the side wall portion 211, thereby facilitating the disassembly of the screen 223. Specifically, for example, by making the swing angle of the screen 223 between 5° and 20°, when it is necessary to disassemble the screen 223, the screen 223 can be rotated clockwise first, thereby moving the fourth end 238 away from the side wall portion 211. At this time, there is a certain gap between the fourth end 238 and the side wall portion 211. Through this gap, when the first fastener 240 of the screen 223 and the second fastener 245 on the side wall portion 211 are disengaged, the screen 223 can be pulled more easily toward the bottom wall portion 210, thereby making it easier to disassemble the screen 223.

[0052] Furthermore, by keeping the swing angle below 20°, when the main body 205 is in its initial position, i.e., the bottom wall portion 210 is directly below the main body 205, it is possible to prevent the screen 223 from excessively swinging towards the center of the toilet space 201. This prevents the gap between the screen 223 and the side wall portion 211 from becoming too large, thus preventing pets' hands or feet from getting caught. Moreover, even at the limit of the clockwise swing angle, when the bottom wall portion 210 is directly below the main body 205, the screen 223 does not overlap with the bottom wall portion 210 when viewed from a top-down perspective.

[0053] In the compartment 204 of the embodiment, by adapting the shape of the edge of the fourth end 238 and the circumferential shape of the portion of the side wall 211 located in the return space 225, the gap between the fourth end 238 of the screen 223 and the side wall 211 can be further reduced, thereby suppressing the clump of particles 209 from falling into the return space 225 from the gap.

[0054] In the chamber 204 of the embodiment, by making the screen 223 an elastic element, the particles 209 can be made to fall more easily. For example, when the screen 223 is subjected to gravity and undergoes a certain degree of elastic deformation, the shape and / or position of the screen holes 231 of the screen 223 may shift to a certain extent, thereby making it easier for slightly stuck particles 209 to fall off.

[0055] Furthermore, by making the screening surface 223a of the screen 223 as an arc shape, and installing the screen 223 onto the side wall 211 with the protruding arc surface of the screening surface 223a facing the bottom wall 210, the overall support strength of the screen 223 can be improved, and the excessive deformation caused by the pressure of the particles 209 on the screen 223 can be suppressed.

[0056] In the compartment 204 of the embodiment, the screen 223 can be easily installed or removed by using a snap-fit ​​connection structure.

[0057] Furthermore, by making the cross-sectional shape of the slot 241 of the first fastener 240 and the protrusion 246 of the second fastener 245 mutually compatible elliptical, the oscillation angle of the screen 223 relative to the side wall 211 is suppressed while allowing the screen 223 to swing relative to the side wall 211. Therefore, no additional structures are needed to limit the oscillation angle of the screen 223.

[0058] Furthermore, by narrowing the opening 242 of the first fastener 240 relative to the middle of the slot 241, and by allowing the opening 242 of the first fastener 240 to expand outward when squeezed, it is possible to easily install the screen 223 without the need for other tools, while ensuring that the screen 223 is reliably held on the side wall portion 211 by the fastening structure without external force.

[0059] Additionally, it should be noted that while the above embodiment illustrates an example where a slot 241 is formed on the first fastener 240 and a protrusion 246 is formed on the second fastener 245, it is not limited to this. For example, the protrusion 246 may be formed on the first fastener 240, and the slot 241 may be formed on the second fastener 245.

[0060] In the above embodiment, although an example was described where the cross-section of the groove 241 and the protrusion 246 is elliptical, allowing the screen 223 to swing relative to the sidewall 211 within a predetermined angle range, this is not a limitation. For example, a limiting portion may be formed above the first latching member 240 of the sidewall 211, thereby limiting the angle at which the screen 223 swings upward (clockwise). This limiting portion may also be integrally formed with the first latching member 240. In this case, the cross-section of the groove 241 and the protrusion 246 may also be approximately circular (i.e., circular or nearly circular).

[0061] In the above embodiment, although an example of the screen 223 being mounted to the side wall portion 211 has been described, it is not limited to this. For example, the screen 223 may also be mounted to the second end 233 of the blocking member 224. Specific mounting structures can be found in such mounting structures as the first snap-fit ​​member 240 and the second snap-fit ​​member 245.

[0062] In the above embodiment, although an example of the screen 223 being able to swing relative to the side wall portion 211 has been described, it is not limited to this. For example, the third end 237 of the screen 223 can also be directly fixed to the side wall portion 211 by various fixing means such as threaded connection.

[0063] Continue to refer to Figure 7The following is a brief description of the structure that makes compartment 204 rotate.

[0064] For example, the outer casing 203 may be provided with a support assembly 226 for rotatably 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.

[0065] 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.

[0066] 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.
