Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of pet supplies technology, and in particular to a pet toileting 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 "litter box" for ease of explanation) as an example, a typical 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. When cleaning the inside of the compartment is needed, these clumps of cat litter are removed, thus cleaning up the cat excrement along with the litter.

[0003] While cleaning clumps of litter can reduce odor in the litter box to some extent, the odor will gradually worsen over time, and bacteria can easily grow. Therefore, a thorough cleaning of the entire litter box is necessary. In known litter boxes, cleaning agents are typically used to clean the litter box directly. However, this can lead to the cleaning agent contaminating other parts of the litter box (such as the base), and water stains may seep into these areas, causing further cleaning problems. Utility Model Content

[0004] This invention addresses the aforementioned technical problems by proposing a pet toilet device that makes cleaning the pet's enclosure easier.

[0005] The pet toileting device according to this utility model includes: a housing, wherein a first mounting cavity is formed within the housing, the first mounting cavity having an inlet and outlet, and a support portion is provided within the first mounting cavity, the support portion being open toward the inlet and outlet; a compartment, capable of being accommodated in or removed from the first mounting cavity via the inlet and outlet, the compartment having a supported portion, wherein when accommodated in the first mounting cavity, the compartment is supported on the support portion by the supported portion and is rotatable relative to the housing; and a locking portion, configured to be openable or closed relative to the housing, wherein when closed relative to the housing, the compartment is held together with the support portion to hold the compartment, and when open relative to the housing, the compartment can be removed from the first mounting cavity via the inlet and outlet.

[0006] Beneficial effects The pet toilet device of this invention allows for easy cleaning of the compartment by removing it from the outer casing. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this implementation are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this implementation, and should not be construed as limiting this implementation.

[0020] In the description of this embodiment, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this embodiment.

[0021] In the description of this embodiment, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0022] In the description of this embodiment, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" 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] The following is for reference Figures 1 to 11 This describes a pet toileting device according to an embodiment. It should also be noted that the accompanying drawings have been optimized to some extent for ease of illustration. For example, in... Figure 3 as well as Figure 4 For ease of illustration, the first shell 251 within the outer shell 203 is partially cut open. Figures 5 to 11 In this illustration, the views do not necessarily correspond strictly; some structural features that are not explicitly shown are omitted as needed. For example, in... Figure 11 For ease of illustration, the illustration of handle 304 has been removed.

[0024] Main reference Figure 1 , Figure 3 as well as Figure 4 The pet toileting device according to the embodiment includes: a housing 203, a compartment 204, and a locking part 300. A first mounting cavity 248 is formed within the housing 203, and the first mounting cavity 248 has an inlet and outlet 206. A support part 249 is provided within the first mounting cavity 248, and the support part 249 is open toward the inlet and outlet 206 (i.e., the support part 249 can be accessed unobstructed from the direction of the inlet and outlet 206). The compartment 204 is used for pet toileting. The compartment 204 can be accommodated within or removed from the first mounting cavity 248 via the inlet and outlet 206. The compartment 204 has a supported part 250, and when accommodated within the first mounting cavity 248, the compartment 204 is supported on the support part 249 by the supported part 250 and is rotatable relative to the housing 203. The locking part 300 is configured to be openable or closed relative to the housing 203. When closed relative to the outer casing 203, the locking part 300 and the support part 249 together hold the compartment 204. When open relative to the outer casing 203, the compartment 204 can be removed from the first mounting cavity 248 via the inlet and outlet 206.

[0025] Since the pet toilet device of the embodiment can be detached from the housing 203, the compartment 204 can be cleaned from the outside of the housing 203, and the compartment 204 can be cleaned easily.

[0026] Continue to refer to Figures 1 to 4 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 referred to as a "litter box." In addition to the outer shell 203, the chamber 204, and the locking part 300 (for ease of explanation, the overall structure including these components will sometimes be referred to as the "chamber part 200"), the pet toileting device may also include a base 100 supported on a floor or table. The base 100 includes a pedestal 101, which forms a collection space 102 for collecting pet excrement. The chamber part 200 can be installed as a house on the pedestal 101 of the base 100. A toileting space 201 is formed within the chamber 204, in which the pet relieves itself. In addition, an opening 103 is formed between the base 100 and the cabin portion 200. The opening 103 includes a portion formed on the base 101 and a portion formed on the outer shell 203. The opening 103 can be opened or closed, for example, through a door portion 500 having a double-door structure.

[0027] The outer shell 203 of the compartment 200 is supported on the base 101 of the base 100 and communicates with the collection space 102 through the opening 103. The outer shell 203 and the compartment 204 are generally hemispherical in shape; in other words, both the outer shell 203 and the compartment 204 are open. When the compartment 204 is rotated so that the entrance and exit 206 of the toilet space 201 and the outer shell 203 are in approximately the same position, the pet can enter and exit the toilet space 201 through the entrance and exit 206. When the compartment 204 is rotated to the position where the toilet space 201 and the opening 103 communicate, excrement falls from the compartment 204 and through the opening 103 into the collection space 102.

[0028] Continue to refer to Figure 5 as well as Figure 6 and supplementary reference Figure 3 as well as Figure 4The outer shell 203 mainly includes a first shell 251 and a second shell 252, which overlap each other. The first shell 251 and the second shell 252 can be integrally manufactured using known processing methods such as injection molding, but are not limited to these methods. For example, from the perspective of reducing processing difficulty and improving aesthetics, the first shell 251 and the second shell 252 can be formed by splicing together multiple smaller shells. The first shell 251 is located on the outside of the outer shell 203, and the second shell 252 is located on the inside of the outer shell 203. The first shell 251 wraps around the second shell 252 from the outside. The overall appearance of the first shell 251 is a smooth hemispherical shape, and the first shell 251 mainly serves as the exterior part of the compartment 200 of the pet toilet device. The first mounting cavity 248 is mainly defined by the second shell 252; that is, the entire compartment 204 is covered by the second shell 252. A second mounting cavity 253 is formed between the first housing 251 and the second housing 252, and a part of the pet toilet device for cooperating with the locking part 300 (described later) and a drive device 270 for driving the chamber 204 to rotate (described later) are installed in the second mounting cavity 253.

[0029] The outer casing 203 has receiving grooves 254 formed on both sides in the width direction (left and right sides in the attached figure). The receiving grooves 254 communicate with the first mounting cavity 248 and open towards the inlet / outlet 206. The receiving groove 254 on the left and the receiving groove 254 on the right are opposite each other in the left-right direction. The receiving grooves 254 are mainly used to accommodate at least a part of the support part 249, at least a part of the supported part 250 of the compartment 204, and the locking part 300. The receiving grooves 254 are mainly formed in the second casing 252, and when viewed from the left-right direction, the receiving grooves 254 are generally U-shaped. The inner sides of the receiving grooves 254 in the left-right direction communicate with the first mounting cavity 248 (therefore, the receiving grooves 254 can sometimes be regarded as part of the first mounting cavity 248), while the outer sides of the receiving grooves 254 in the left-right direction are covered by the first casing 251. A generally U-shaped first stepped portion 255 is formed in the receiving groove 254. The first stepped portion 255 extends along the U-shaped edge of the receiving groove 254. Furthermore, the first stepped portion 255 protrudes from the side of the second housing 252 adjacent to the first housing 251 in a left-right direction towards the side opposite to the first housing 251. At least one of the two first sidewalls 256 of the receiving groove 254 is formed with a guide strip 257. The guide strip 257 extends from the side of the second housing 252 located at the inlet / outlet 206 towards the bottom of the receiving groove 254, and extends approximately to the end of the first stepped portion 255. Locking holes 258 are formed on the two first sidewalls 256 of the receiving groove 254, each locking hole 258 penetrating the first sidewall 256 and communicating with the second mounting cavity 253. The two locking holes 258 are opposite to each other. The shape of the locking holes 258 is not particularly limited; for example, it can be a circle, an ellipse, a square, a triangle, or various other shapes.

[0030] The support portion 249 includes two side support assemblies 259, which are respectively disposed on both sides of the first mounting cavity 248 in the width direction. Correspondingly, the supported portion 250 of the compartment 204 includes two support shafts 260, which are respectively disposed on both sides of the compartment 204 in the width direction. When the compartment 204 is accommodated within the first mounting cavity 248, the two support shafts 260 are respectively supported on the two side support assemblies 259.

[0031] Two side support assemblies 259 are respectively disposed in two receiving grooves 254. It should be noted that the structures of the two side support assemblies 259 are largely the same; therefore, they will be described as a whole, with differences mentioned where necessary. Each side support assembly 259 includes a plurality of first support rollers 261 arranged circumferentially. The plurality of first support rollers 261 surround at least a portion of the lower circumferential portion 262 of the support shaft 260 and support the support shaft 260. Here, the lower circumferential portion 262 of the support shaft 260 refers to the portion of the support shaft 260 located below the plane formed by the front-rear and left-right directions, when the support shaft 260 is radially transversely cut through its axis in a way that passes through the center of the plane. Furthermore, the upper circumferential portion 263 refers to the portion of the support shaft 260 located above the plane.

[0032] Specifically, the first support roller 261 is rotatably mounted on the first step 255 in a direction of rotation consistent with that of the compartment 204. The circumferential edge of the first support roller 261 protrudes from the first step 255, thereby supporting the support shaft 260 of the compartment 204. The type of the first support roller 261 is not particularly limited; for example, it can be a roller made of wear-resistant metal or resin materials. Furthermore, commercially available bearings (such as deep groove ball bearings or roller bearings) can also be used. The mounting method of the first support roller 261 is also not particularly limited; for example, it can be rotatably mounted on the first step 255 using a known shaft-supported method. Additionally, a first cover plate 264 is detachably mounted on the first step 255. The first cover plate 264 is used to restrict the first support roller 261 axially along its axis to prevent it from falling off. The first support roller 261 may include three or more, one of which is located at the bottom of the first step 255 and serves as the primary support point when supporting the support shaft 260 of the support compartment 204. Based on the bottom first support roller 261, at least one additional first support roller 261 is distributed on each side of the lower circumferential portion 262 of the support shaft 260. These two first support rollers 261 serve as auxiliary support points and also radially restrict the support shaft 260, suppressing excessive movement of the support shaft 260. For example, in a specific example, the first support roller 261 may include five, one located at the bottom of the first step 255, and of the other four, two are located on one side of the extension direction of the first step 255 and support one side of the lower circumferential portion 262 of the support shaft 260 of the support compartment 204, and two are located on the other side of the extension direction of the first step 255 and support the other side of the lower circumferential portion 262 of the support shaft 260 of the support compartment 204.

[0033] Continue to refer to Figure 7 as well as Figure 8The chamber 204 includes a main body 205, which is a shell-like structure defining a toilet space 201. The toilet space 201 contains a baffle 224 and a screen 223 for separating clumps of particulate matter. The baffle 224 is positioned along the rotation direction of the main body 205 (in the attached drawing, this is the rotation direction in a plane formed by the front-back and up-down directions) and forms a return flow space (not shown) between it and the inner side 211a of the main body 205, leading towards the bottom of the toilet space 201. The screen 223 is positioned along the rotation direction of the main body 205 between the bottom of the toilet space 201 and the return flow space. The toilet space 201 is filled with particulate matter (not shown) for combining with pet excrement. When the main body 205 is rotated clockwise, for example, in a plane formed by the front-back and up-down directions, the toilet space 201 rotates from one side (e.g., the front) to the other side (e.g., the rear) and gradually downwards. Particles fall onto the screen 223. Ordinary particles (i.e., particles not combined with pet excrement) pass through the screen holes of the screen 223 and fall into the return space. Clump-shaped particles, because their cross-section is larger than the size of the screen holes of the screen 223, cannot pass through and continue to fall onto the baffle 224, then along the baffle 224 into the collection space 102. After cleaning, the main body 205 is rotated counterclockwise. At this time, the toilet space 201 rotates from bottom to top, and ordinary particles collected in the return space pass through the screen holes of the screen 223 and return to the bottom of the toilet space 201.

[0034] The two support shafts 260 of the supported portion 250 of the compartment 204 are integrally formed with the main body 205 of the compartment 204 and are coaxial along the left-right direction of the main body 205. The two support shafts 260 may be formed, for example, on an axis close to the center of gravity of the compartment 204, or they may be formed below the axis of the center of gravity of the compartment 204. One of the two support shafts 260 has a second stepped portion 265, that is, one of the support shafts 260 has a large-diameter portion 260a and a small-diameter portion 260b, and the second stepped portion 265 is formed axially between the large-diameter portion 260a and the small-diameter portion 260b. When the support shaft 260 is supported by its corresponding side support assembly 259, the small-diameter portion 260b of the support shaft 260 is supported on the first support roller 261. Furthermore, the second stepped portion 265 and the first stepped portion 255 of the side support assembly 259 are opposite each other in the left-right direction and located inside the first stepped portion 255. Another of the two support shafts 260 may be provided with a first transmission member 266, which is coaxial with the support shaft 260 and located at the end of the support shaft 260 near the main body 205. Furthermore, the first transmission member 266 can be integrally formed with the support shaft 260 or detachably nested within the support shaft 260. When the support shaft 260 is supported by its corresponding side support assembly 259, the first transmission member 266 and the first stepped portion 255 of the side support assembly 259 are opposite each other in the left-right direction and located inside the first stepped portion 255.

[0035] Therefore, with the compartment 204 housed within the first mounting cavity 248, the two support shafts 260 are respectively supported on the first support rollers 261 of the side support assembly 259. Furthermore, since the second step 265 and its corresponding first step 255 are opposite each other in the left-right direction, and the first transmission member 266 and its corresponding first step 255 are also opposite each other in the left-right direction, the displacement of the compartment 204 in the left-right direction is restricted, preventing the compartment 204 from falling off in the left-right direction.

[0036] Furthermore, the support portion 249 of the outer casing 203 may also include a bottom support assembly 267, which is disposed at the center of the width direction of the first mounting cavity 248 and extends along the rotation direction of the compartment 204. Correspondingly, the supported portion 250 of the compartment 204 includes a supported strip 268 disposed at the center of the width direction of the compartment 204 and extending along the rotation direction of the compartment 204. When the compartment 204 is accommodated within the first mounting cavity 248, the supported strip 268 can be supported by the bottom support assembly 267.

[0037] It should be noted that the middle portion of the width direction of the first mounting cavity 248 can include all areas in the left-right direction of the first mounting cavity 248 except for the sides, and is not limited to the exact center of the width direction of the first mounting cavity 248. The bottom support assembly 267 can include two sets spaced apart in the left-right direction. Each set of bottom support assemblies 267 includes a plurality of second support rollers 269, which are installed inside the first mounting cavity 248 on the inner side of the main body 205 and spaced apart along the rotation direction of the compartment 204. The installation method of the second support rollers 269 is not particularly limited; for example, they can be installed by means of shaft support.

[0038] It should be noted that the central part of the width direction of the compartment 204 can include all areas of the compartment 204 in the left-right direction except for the sides, and is not limited to the exact center of the width direction of the compartment 204. The support bar 268 is integrally formed with the main body 205, for example, and extends on the outer surface of the main body 205 along the rotation direction of the compartment 204. The support bar 268 may also include two sets spaced apart in the left-right direction. Each support bar 268 can be supported by the second support roller 269. In addition, each support bar 268 can also enhance the overall strength of the main body 205 of the compartment 204.

[0039] Here, we will explain the case where the supported bar 268 can be supported by the bottom support assembly 267. Specifically, in the pet toilet device of this embodiment, the side support assembly 259 of the support part 249 serves as the main support part of the outer shell 203, and the support shaft 260 serves as the main supported part of the compartment 204. The bottom support assembly 267 serves as an auxiliary support part of the outer shell 203. When the compartment 204 is empty, that is, when the compartment 204 is not filled with excessive particles, the supported bar 268 and the bottom support assembly 267 do not need to contact each other. When the compartment 204 is filled with a certain amount of particles, the main body 205 may deform (sag) to a certain extent due to the weight of the particles. In this case, the torque required to rotate the main body 205 may increase sharply. Therefore, by providing the bottom support assembly 267, when the main body 205 deforms, the main body 205 is supported by the bottom support assembly 267, thereby providing auxiliary support for the main body 205 and suppressing the amount of deformation of the main body 205. Therefore, it is possible to suppress problems such as overload of the drive unit 270 caused by a sharp increase in the torque required by the rotating body 205.

[0040] Continue to refer to Figures 9 to 11 and supplementary reference Figure 3 as well as Figure 4As described above, when the locking part 300 is closed relative to the outer casing 203, the locking part 300 and the support part 249 together clamp the compartment 204. Here, clamping is not limited to a tight clamping state; any situation where the locking part 300 and the support part 249 together restrict the radial movement of the compartment 204 along the support shaft 260 can be considered clamping. Specifically, there are two locking parts 300, respectively disposed on both sides of the outer casing 203 in the width direction. When closed relative to the outer casing 203, the locking parts 300 and the side support assembly 259 together clamp the support shaft 260 radially, allowing the support shaft 260 to rotate freely. When open relative to the outer casing 203, the locking parts 300 open the support part 249 toward the inlet / outlet 206. The two locking parts 300 can cover the receiving groove 254 from one side of the inlet and outlet 206, thereby restricting the support shaft 260 in the vertical direction together with the side support assembly 259, while on the other hand, the locking parts 300 as a whole can be hidden in the receiving groove 254, improving the overall appearance of the cabin part 200.

[0041] The locking part 300 can be opened relative to the housing 203 by being detached from it. The locking part 300 includes a mounting base 301, a locking member 302, a resilient member 303, and a handle 304. When the locking part 300 is closed relative to the housing 203, the mounting base 301 restricts the support shaft 260 from one side of the inlet / outlet 206. The locking member 302 is telescopically mounted to the mounting base 301. When the locking part 300 is closed relative to the housing 203, the locking member 302 extends and engages with the housing 203. The resilient member 303 is mounted to the mounting base 301 and applies force to the locking member 302 in a manner that causes the locking member 302 to retract relative to the mounting base 301. The handle 304 is mounted to the mounting base 301 and applies force to the locking member 302 in a manner that causes the locking member 302 to extend relative to the mounting base 301.

[0042] Before the locking part 300 is installed into the receiving groove 254, the handle 304 does not apply force to the locking member 302; that is, the locking member 302 is in a retracted state relative to the mounting base 301 due to the force of the elastic member 303. When installing the locking part 300, the locking part 300 is inserted into the receiving groove 254 from above, and the mounting base 301 of the locking part 300 is pushed towards the bottom of the receiving groove 254 along the guide strip 257 formed on the first side wall 256 of the receiving groove 254. When the mounting base 301 is pushed to approximately the end of the first step 255, the locking member 302 and the locking holes 258 formed on the two first side walls 256 of the receiving groove 254 are opposite each other. At this time, the handle 304 is operated to apply force to the locking member 302, the elastic member 303 is compressed, and the locking member 302 extends out from the mounting base 301 and is inserted into the locking hole 258. Thus, the locking part 300 is closed relative to the outer casing 203. At this time, the locking part 300 covers the receiving groove 254, and the mounting base 301 of the locking part 300 restricts the support shaft 260 from above, thereby suppressing the situation where the support shaft 260 jumps when the compartment 204 is rotated.

[0043] In this manner, the locking part 300 is opened relative to the housing 203 by removing the mounting base 301 from the housing 203. Specifically, when it is necessary to open the locking part 300, the handle 304 is operated so that no force is applied to the locking member 302. At this time, due to the force of the elastic member 303, the locking member 302 retracts relative to the mounting base 301, thereby retracting the locking member 302 from the locking hole 258 of the housing 203. At this time, while holding the handle 304, the locking part 300 is lifted upward toward the inlet / outlet 206, thereby removing the mounting base 301 of the locking part 300 entirely from the housing 203. With the locking part 300 in the removed state, the receiving groove 254 opens toward the inlet / outlet 206, and the side support assembly 259 also opens toward the inlet / outlet 206. Thus, the compartment 204 can be removed from the first mounting cavity 248.

[0044] The mounting base 301 of the locking part 300 can be a component integrally formed using a resin material or the like. The width of the mounting base 301 is slightly smaller than the width of the receiving groove 254. The mounting base 301 has second side walls 305 located on both sides in the width direction. When the locking part 300 covers the receiving groove 254, the second side walls 305 of the mounting base 301 and the first side walls 256 of the receiving groove 254 are opposite to each other. A mounting groove 306 is formed in the mounting base 301, which generally spans the width direction of the mounting base 301. That is, the extending direction of the mounting groove 306 is approximately orthogonal to the direction in which the mounting base 301 is inserted into the receiving groove 254. In other words, the direction in which the mounting base 301 restricts the support shaft 260 is orthogonal to the direction in which the locking member 302 engages with the housing 203. Furthermore, clearance holes 307 are formed on the two second side walls 305 of the mounting base 301, and the clearance holes 307 communicate with the mounting groove 306. The shape of the clearance hole 307 is not particularly limited. For example, the shape of the clearance hole 307 can be approximately the same as the shape of the locking hole 258 of the housing 203. Two stops 308 are formed in the mounting groove 306, and the two stops 308 are respectively located on the inner side of the mounting base 301 and opposite to the clearance hole 307.

[0045] The locking element 302 comprises two members, one of which is slidably mounted in the mounting groove 306 through one of the stops 308, and the other is slidably mounted in the groove 306 through the other stop 308. The locking element 302 slides along the mounting groove 306 to extend beyond the mounting base 301 via a clearance hole 307, or retracts from the mounting base 301 via the clearance hole 307. The two locking elements 302 have substantially the same structure, and the two stops 308 also have substantially the same structure; therefore, the locking elements 302 and stops 308 will be described as a whole below. Specifically, the locking element 302 may include a lock head 309 and a driven block 310 located at the other end of the lock head 309. The lock head 309 is located outside the stop 308, and the driven block 310 is located inside the stop 308. The lock cylinder 309 has a head (not marked with reference numerals) and a tail (not marked with reference numerals). The diameter of the head of the lock cylinder 309 is larger than the diameter of the tail. The tail of the lock cylinder 309 passes through a stop 308 and connects to the driven block 310. The head of the lock cylinder 309 is blocked by the stop 308 and abuts against the stop 308. The driven block 310 of the locking member 302 can be detachably installed to the tail of the lock cylinder 309 by various connection methods such as screws. The driven block 310 has a driven portion 311, which can be an inclined surface.

[0046] Two elastic elements 303 are included, one of which drives one locking element 302, and the other drives the other locking element 302. The elastic element 303 can be a compression type coil spring. The elastic element 303 is fitted into the tail of the lock head 309, with one end abutting against the stop block 308 and the other end abutting against the driven block 310. In the initial state, due to the inward force of the elastic element 303, the lock head 309 of the locking element 302 abuts against the stop block 308 inward. At this time, the locking element 302 is completely retracted into the mounting base 301 and does not protrude from the clearance hole 307 of the mounting base 301. When the driven block 310 of the locking member 302 is pushed outward by the handle 304, the locking member 302 moves outward along the mounting groove 306 toward the mounting base 301. At this time, the elastic member 303 is compressed, and the lock head 309 of the locking member 302 extends out of the mounting base 301 through the clearance hole 307.

[0047] The handle 304 is rotatably mounted to the mounting base 301. Specifically, the mounting base 301 has a hinge hole (not marked in the drawing) formed above the mounting groove 306. The handle 304 is hinged to this hinge hole via a hinge shaft (not marked in the drawing), thereby allowing the handle 304 to swing relative to the mounting base 301. The handle 304 has a grip plate 312, which allows the handle 304 to rotate entirely relative to the mounting base 301 when operated by the operator. The grip plate 312 spans the width of the mounting base 301 and has a flat portion 313 and a bent portion 314, which are integrally formed. The grip plate 312 is hinged to the mounting base 301 approximately at the junction of the flat portion 313 and the bent portion 314. When the handle 304 is oriented in the release direction (e.g.) Figure 10 When the handle 312 is rotated clockwise, the flat portion 313 of the handle 312 moves away from the mounting base 301, while the bent portion 314 of the handle 312 abuts against the mounting base 301, thereby limiting the unfolding angle of the handle 312. The handle 304 has a drive block 315, which moves with the handle 304 in the locking direction (e.g., clockwise). Figure 11The handle 304 rotates counterclockwise, pushing the locking member 302 to extend relative to the mounting base 301. The drive block 315 is connected to the grip plate 312, but the connection method is not particularly limited; for example, the drive block 315 can be connected by various methods such as threaded connection, snap-fit, or integral molding. The drive block 315 has protruding drive portions 316 at both ends, with each drive portion 316 located inside the mounting base 301 and opposite to the respective driven blocks 310 of the two locking members 302. When the handle 304 is rotated toward the locking direction, the grip plate 312 approaches the mounting base 301, and simultaneously, the two drive portions 316 of the drive block 315 abut against the inclined surfaces of the driven blocks 310 of the two locking members 302, which serve as driven portions 311. When the handle 304 is further rotated toward the locking direction, the two drive portions 316 slide along the inclined surfaces of the driven blocks 310, thereby pushing the locking member 302 outward from the mounting base 301.

[0048] Furthermore, after the locking member 302 is driven by the drive block 315 of the handle 304 and extends out of the mounting base 301, the locking member 302 and the handle 304 are temporarily fixed to each other. Without external force in the release direction, the drive portion 316 of the drive block 315 of the handle 304 and the driven portion 311 of the locking member 302 remain in contact with each other. For example, a check portion 317 may be formed on the locking member 302. The check portion 317 is configured to restrict the drive block 315 in the release direction opposite to the locking direction after the handle 304 is rotated to a predetermined position in the locking direction. As described above, the driven block 310 has a driven portion 311, which may be an inclined surface. The check portion 317 may be formed at the end of the inclined surface of the driven portion 311. That is, when the drive portion 316 slides along the inclined surface and reaches the position (predetermined position) of the check portion 317, the check portion 317 restricts the handle 304 from rotating in the release direction. The check valve 317 can be a check valve plane, a check valve protrusion, a check valve groove, etc., formed at the end of the inclined surface. As a check valve plane, for example, its normal can be parallel to the direction of force application of the elastic member 303.

[0049] As described above, while the handle 304 drives the locking member 302, the elastic member 303 is compressed, meaning the handle 304 experiences a force from the elastic member 303. When the driving portion 316 of the driving block 315 of the handle 304 slides along the inclined surface of the locking member 302, the handle 304 experiences an inward component force from the elastic member 303 and a component force in the release direction of the handle 304. However, after the driving portion 316 of the driving block 315 of the handle 304 crosses the inclined surface and abuts against the check portion 317, the handle 304 mainly experiences an inward force from the elastic member 303, and there is no actual component force in the release direction of the handle 304. Therefore, the locking member 302 and the handle 304 temporarily remain stable relative to each other. Furthermore, due to the force exerted by the two elastic members 303, the two locking members 302 reliably clamp the drive block 315 of the handle 304, thus reliably maintaining the abutment state between the locking members 302 and the handle 304 and suppressing the rotation of the handle 304. That is, in the absence of external force in the release direction, the handle 304 can be reliably held in the locked state.

[0050] As described above, when the locking part 300 is closed relative to the housing 203, the mounting base 301 restricts the support shaft 260 from one side of the inlet / outlet 206. Specifically, a notch 318 is formed at the lower part of the mounting base 301 that is at least partially adapted to the circumferential portion 263 of the support shaft 260. When the locking part 300 is locked to the housing 203, the notch 318 restricts the support shaft 260 from above, thereby suppressing the support shaft 260 from jumping or the like. In addition, a plurality of limiting rollers 319 may be mounted on the mounting base 301. The plurality of limiting rollers 319 are arranged at circumferential intervals along the notch 318, and the plurality of limiting rollers 319 are arranged such that when the locking part 300 is closed relative to the housing 203, they surround at least a portion of the radial circumferential portion 263 of the support shaft 260. Furthermore, the type of limiting roller 319 is not particularly limited. For example, it can be a roller made of wear-resistant metal or resin materials. Additionally, commercially available bearings (such as deep groove ball bearings or roller bearings) can also be used. Furthermore, the mounting method of the limiting roller 319 is not particularly limited. For example, it can be rotatably mounted to the mounting base 301 using a known method of shaft support. Additionally, a second cover plate 320 can be detachably mounted on the mounting base 301. The second cover plate 320 is used to restrict the limiting roller 319 along its axial direction, preventing it from falling off.

[0051] When the locking part 300 is closed relative to the housing 203, the multiple limiting rollers 319 provided on the mounting base 301 and the first support roller 261 of the side support assembly 259 together surround the entire circumference of the support shaft 260, thereby suppressing radial runout of the support shaft 260 while the side support assembly 259 rotates.

[0052] Continue to refer to Figure 3 as well as Figure 4 The pet toileting device of the embodiment may also include a detector 321 for detecting the locking status of the locking part 300. For example, the detector 321 is disposed in the housing 203 for detecting the state in which the locking member 302 is engaged with the housing 203. The detector 321 is installed in the second mounting cavity 253 of the housing 203 and is located near the receiving groove 254. The detector 321 can directly detect the locking member 302. For example, when the lock head 309 of the locking member 302 extends into the locking hole 258, the detector 321 directly detects the lock head 309. The type of detector 321 is not particularly limited. Examples include: non-contact sensors such as photoelectric sensors, fiber optic sensors, proximity sensors, etc.; and contact sensors such as mechanical limit switches (micro switches), pressure sensors, etc.

[0053] Not limited to this, detector 321 can also indirectly detect the state of locking member 302 being engaged with housing 203. For example, housing 203 may also have a detection block 322. When locking member 302 is engaged with housing 203, detection block 322 is pushed by locking member 302 and approaches detector 321. Detection block 322 is slidably installed in the second mounting cavity 253 of housing 203 and located near receiving groove 254. For example, one end of detection block 322 has a plug (not marked in the figure). In the initial state, the plug of detection block 322 blocks locking hole 258, and the other end of detection block 322 is fitted with a compression spring (not shown). The compression spring applies force to detection block 322 in such a way that the plug blocks locking hole 258. When locking part 300 is installed in receiving groove 254 and locking member 302 is driven by handle 304, locking head 309 of locking member 302 pushes detection block 322, thereby making detection block 322 detected by detector 321.

[0054] By setting up this detector 321, the installation status of the locking part 300 can be confirmed. For example, when the locking part 300 is accurately closed, the detector 321 detects the locking element 302 or the detection block 322 and sends the detected signal to the control system of the pet toilet device, etc.

[0055] As described above, the chamber 204 is rotatable relative to the outer casing 203 (support 249). The pet toilet device of this embodiment can drive the chamber 204 to rotate via a drive device 270. For example, the drive device 270 is disposed in the outer casing 203 and connected to the support shaft 260, thereby driving the chamber 204 to rotate. The drive device 270 is disposed in the second mounting cavity 253 of the outer casing 203 and located near the support shaft 260. The drive device 270 includes a motor 229, the aforementioned first transmission member 266, and a second transmission member 271. As described above, the first transmission member 266 is disposed on one of the support shafts 260, and the second transmission member 271 is, for example, mounted on the outer casing 203. The types of the first transmission member 266 and the second transmission member 271 are not particularly limited; for example, they can be gear drives, synchronous belt drives, etc. From the perspective of ease of installation, gear drives are preferred. The motor 229 is connected to the support shaft 260 via the second transmission member 271 and the first transmission member 266. Thus, the drive unit 270 can drive the compartment 204 to rotate.

[0056] This pet toileting device, according to this embodiment, allows for easy cleaning of the compartment 204 by removing it from the outer casing 203, enabling cleaning of the compartment 204 from the outside of the casing 203. Specifically, when the compartment 204 is in normal operation, the locking part 300 is inserted into the receiving groove 254, thus closing it relative to the outer casing 203. At this time, the limiting roller 319 provided on the mounting base 301 of the locking part 300 and the first support roller 261 provided on the side support assembly 259 together surround and clamp the support shaft 260 of the compartment 204, thus forming a bearing seat for the support shaft 260. This allows the compartment 204 to rotate stably. When it is necessary to clean the compartment 204, since the locking part 300 can be opened relative to the outer casing 203, and in the open state, the support part 249 is open toward the inlet / outlet 206, allowing the compartment 204 to be removed from the first mounting cavity 248 without obstruction via the inlet / outlet 206. Therefore, this pet toilet device according to the embodiment can easily clean the compartment 204, reducing the possibility of contamination of other parts of the pet toilet device when cleaning the compartment 204.

[0057] In the pet toileting device of the embodiment, receiving grooves 254 are formed on both sides of the outer casing 203 in the width direction. The receiving grooves 254 communicate with the first mounting cavity 248 and open toward the inlet / outlet 206. Two side support components 259 are respectively disposed in the receiving grooves 254. As a result, the side support components 259 can be compactly arranged, so that the first housing 251 of the outer casing 203 and the like do not need to be adapted to the side support components 259, and the aesthetics of the design can be improved.

[0058] In addition, since the locking part 300 covers the receiving groove 254 from one side of the inlet and outlet 206, the locking part 300 can form an integral part with the outer shell 203 when it is closed, which can improve the aesthetics of the design.

[0059] In the pet toileting device of the embodiment, in the locking part 300, the locking member 302 is retracted relative to the mounting base 301 by the elastic member 303, and the locking member 302 is extended relative to the mounting base 301 by the handle 304, so that the locking part 300 can be easily opened relative to the housing 203. For example, the locking part 300 can be opened by operating the handle 304 with one hand. Similarly, the locking part 300 can also be closed by operating the handle 304 with one hand.

[0060] Furthermore, by making the direction in which the mounting base 301 restricts the support shaft 260 orthogonal to the direction in which the locking member 302 engages with the housing 203, it is possible to prevent the locking part 300 from dislodging when the compartment 204 rotates. For example, when the compartment 204 rotates, the support shaft 260 of the compartment 204 may exert an upward force on the mounting base 301. At this time, since the direction in which the locking member 302 engages with the housing 203 is orthogonal to the direction in which the support shaft 260 of the compartment 204 exerts a force on the mounting base 301, it is possible to suppress the loosening of the mounting base 301 toward the inlet / outlet 206, and the support shaft 260 can be reliably restricted.

[0061] In the pet toileting device of the embodiment, by forming a check portion 317 on the locking member 302, it is possible to prevent the handle 304 from accidentally rotating in the release direction, thereby causing the locking portion 300 to loosen.

[0062] In the pet toileting device of the embodiment, by providing a detector 321 for detecting the state of the locking member 302 being locked into the outer casing 203, it can be ensured that the compartment 204 can only start working after the locking part 300 is locked in place, thus preventing the compartment 204 from being accidentally activated, which could lead to damage or injury to the pet.

[0063] In the pet toileting device of the embodiment, by providing a bottom support assembly 267 in the middle of the width direction of the first mounting cavity 248, the chamber 204 can be supported from the bottom, the deformation of the main body 205 of the chamber 204 can be suppressed, and the problem of overload of the drive device 270 caused by the sharp increase in the torque required to rotate the main body 205 can be suppressed.

[0064] Furthermore, although the above embodiment illustrates an example where receiving grooves 254 are formed on both sides of the housing 203 in the width direction, it is not limited to this. For example, the housing 203 may not form receiving grooves 254, but instead a support flange surface may be formed at the position of the inlet / outlet 206, and a support portion 249 may be provided on the support flange surface. The support shaft 260 may be clamped together with the support portion 249 by a mechanism such as a quick clamp as a locking portion 300.

[0065] In the above embodiment, although an example of opening the locking part 300 relative to the housing 203 by removing the mounting base 301 from the housing 203 has been described, it is not limited to this. For example, the mounting base 301 may be swayably mounted to the housing 203, and the mounting base 301 may be able to sway to a position that does not coincide with the support shaft 260 when viewed from the direction of the inlet / outlet 206. In this manner, for example, the mounting base 301 may be hinged to the first side wall 256, and the receiving groove 254 may also be open toward the outside of the housing 203, thereby facilitating the swaying of the mounting base 301, etc.

[0066] In the above embodiments, although an example has been described where the elastic member 303 retracts the locking member 302 relative to the mounting base 301 and the handle 304 extends the locking member 302 relative to the mounting base 301, the embodiments are not limited thereto. For example, it is also possible for the elastic member 303 to extend the locking member 302 relative to the mounting base 301 and the handle 304 to retract the locking member 302 relative to the mounting base 301.

[0067] Furthermore, while the example given is that the handle 304 and the locking element 302 are different components, this is not a limitation. For example, the handle 304 and the locking element 302 can actually be integrally formed components, in which case the handle 304 and the locking element 302 are slidably received in the mounting groove 306 of the mounting base 301. For example, the handle 304 and the locking element 302 can be configured as a pin that is inserted into the locking hole 258.

[0068] In the above embodiments, although an example of the support portion 249 including the bottom support assembly 267 has been described, it is not limited to this. If the strength of the main body 205 of the compartment 204 is sufficient, the bottom support assembly 267 may be omitted.

[0069] In the above embodiment, although an example of the compartment 204 being driven by a drive device 270 of a motor 229 has been described, it is not limited to this. The compartment 204 can also be rotated manually relative to the support 249. For example, it can be connected to the support shaft 260 of the compartment 204 via a device such as a rocker arm. When cleaning up excrement, the pet owner can manually operate the compartment 204 to make the toilet space 201 of the compartment 204 face downwards, thereby cleaning up the excrement.

[0070] It should be noted that although the pet toileting device is divided into a base 100 and a housing 200 for ease of explanation, the base 100 and the housing 200 can be assembled together to form the pet toileting device, or they can be originally one piece. For example, although an example is given where the base 100 includes a base 101 and the housing 200 includes a housing 203, the base 101 and the housing 203 can also be integrally formed components. That is, the pet toileting device of the embodiment can include a single housing, with a portion of the housing serving as the base 101 to support the main body 204, and a portion serving as the housing 203 to enclose the main body 204.

[0071] 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.
