Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a cat litter box. Background Technology

[0002] As living standards continue to improve, more and more families are choosing pets for daily companionship, with a relatively high proportion of people keeping cats and other pets. Cats need to use a special litter box to dispose of their waste, and the litter in the litter box needs to be cleaned regularly.

[0003] Currently, automatic litter boxes are commonly used as cat toilets. However, modern automatic litter boxes generally consist of a cat compartment and a base, with the compartment being a single unit. Because the compartment needs to accommodate the cat's entry and exit, it is typically quite large, and this one-piece design poses significant challenges for packaging and transportation. Utility Model Content

[0004] In view of this, it is necessary to propose a litter box that reduces the installation and transportation volume.

[0005] This utility model embodiment provides a cat litter box, which includes a base and a cat compartment. The cat compartment is detachably installed on the base and can rotate relative to the base. The cat compartment includes a first shell component and a second shell component, which are detachably assembled together to form the cat compartment.

[0006] Furthermore, the joint between the first housing component and the second housing component extends around the cat compartment in the direction of its rolling motion.

[0007] Furthermore, the first housing component and the second housing component are respectively provided with a plurality of pairs of first coupling parts and second coupling parts that can be coupled together. Each pair of first coupling parts and second coupling parts can be operably coupled together or decoupled apart, thereby allowing the first housing component and the second housing component to be assembled together or separated from each other.

[0008] Furthermore, the first coupling portion includes a pull tab fixed to the first housing component, and the second coupling portion includes a latch, wherein the pull tab engages with the latch to couple the first housing component and the second housing component.

[0009] Furthermore, the buckle has two spaced-apart engaging walls, each engaging wall having a slot on the side facing the first housing component; the second coupling part includes a latch, a mounting part, and a pivot part, the mounting part being fixed to the second housing component, and the pivot part pivotally connecting the latch to the mounting part so that the latch rotates relative to the second housing component; the latch protrudes towards the first housing component with two spaced-apart hooks, and the latch is inserted into the corresponding slots through the two hooks to lock the latch onto the engaging wall, thereby coupling the second coupling part to the first coupling part.

[0010] Furthermore, the cat compartment has a compartment cavity and an opening communicating with the compartment cavity; the cat litter box also includes a drive device disposed on the base, and the cat compartment also has a gear rack disposed on the first housing component to mesh with the drive device; the gear rack extends from one side of the opening along the joint.

[0011] Furthermore, the driving device includes a motor and a drive gear, the drive gear partially extending through the base and meshing with a rack; when the motor is working, the drive gear is driven by the motor and drives the cat compartment to roll through the rack.

[0012] Furthermore, the litter box also includes a partition disposed in the compartment cavity and a screen disposed adjacent to the partition. The screen is pivotally connected to the cat compartment. A litter collection space is formed between the partition and the interior of the cat compartment. The litter box includes an integrally formed first partition and a second partition. The first partition includes a vertical plane facing away from the litter collection space. The second partition includes a first curved surface protruding into the litter collection space. The screen is disposed adjacent to the second partition and includes a second curved surface protruding away from the litter collection space.

[0013] Furthermore, the second housing component is provided with an assembly part. The base includes a mounting shell, a support shaft detachably fixed to the mounting shell, several support legs, and a waste collection chamber. The support shaft extends from the mounting shell upwards and is rotatably connected to the assembly part, thereby rotatably connecting the cat bin to the base. The several support legs are located below the mounting shell and are used to support the mounting shell. The waste collection chamber is located below the mounting shell and at the location through which the opening passes. When the cat bin rolls, the screen is used to separate cat litter and excrement. The excrement rotates along the partition to the opening and is discharged from the opening into the waste collection chamber. The mounting shell is provided with two oppositely arranged sliding grooves, and the waste collection chamber is provided with two corresponding sliding rails. The waste collection chamber can be pulled out of the mounting shell or installed by means of the sliding rails and the sliding grooves.

[0014] Furthermore, the mounting shell is provided with an arc-shaped mounting groove, and the litter box also includes an arc-shaped top cover. The shape of the top cover is adapted to the shape of the joint. The two ends of the top cover are respectively fixed to the base and are arranged opposite to the mounting shell, thereby forming an installation space together with the mounting shell to accommodate the cat compartment and expose the opposite sides of the first shell component and the second shell component. At the same time, the top cover also covers the opening. The top cover includes a first top cover and a second top cover. The opposite ends of the first top cover and the second top cover are respectively fixed to the base, and the opposite ends of the first top cover and the second top cover are inserted into each other.

[0015] The aforementioned litter box can divide the cat compartment into a first shell component and a second shell component, and the first shell component and the second shell component can be directly assembled together without the need for external fasteners or tools. In addition to reducing the packaging volume and facilitating transportation, it is also relatively easy to assemble. Attached Figure Description

[0064] To provide a clearer and more accurate understanding of the present invention, a detailed description will now be provided in conjunction with the accompanying drawings. The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, and is for illustrative purposes only, and is not a drawing based on the original dimensions.

[0065] Please refer to Figure 1 This application provides a cat litter box 100. The cat litter box 100 includes a base 1, a cat compartment 2, and a drive device 6. The drive device 6 is disposed on the base 1. The cat compartment 2 is detachably mounted on the base 1 and connected to the drive device 6. The cat compartment 2 can rotate relative to the base 1 under the drive of the drive device 6.

[0066] In this embodiment, the cat compartment 2 is a hollow sphere with a cavity 26 inside, which is lined with cat litter. The cat compartment 2 also has a compartment opening 25 and an opening 24 communicating with the cavity 26. The compartment opening 25 allows the cat to enter and exit the cavity 26, meaning the cat can enter and exit the litter box 100 through the compartment opening 25. When the cat defecates, the excrement falls into the litter and is cleaned by the rolling motion of the cat compartment 2, thus automatically cleaning the litter.

[0067] The cat storage compartment 2 includes a first shell component 21 and a second shell component 22 that are detachably assembled together. In this embodiment, the first shell component 21 is the front shell of the cat storage compartment 2, and the opening 25 is located on the first shell component 21. The second shell component 22 is the rear shell of the cat storage compartment 2. That is, in this embodiment, the cat storage compartment 2 is split into two parts in the front-to-back direction, namely, the first shell component 21 and the second shell component 22. Therefore, the joint 23 of the first shell component 21 and the second shell component 22 circles around the cat storage compartment 2 in the direction of its rolling. Figure 7 As shown in P1 and P2, the rotation direction of the cat compartment 2 includes a first rotation direction P1 and a second rotation direction P2. That is, the shape of the joint 23 is adapted to the trajectory formed by the movement of the cat compartment 2 in one revolution. Understandably, in some other embodiments, the cat compartment 2 can also be split into two parts along the vertical direction. Therefore, the joint 23 of the first housing component 21 and the second housing component 22 intersects with the direction of the cat compartment 2's rolling.

[0068] The first housing component 21 and the second housing component 22 are each provided with a plurality of pairs of first coupling parts 210 and second coupling parts 220 that can be coupled together. Each pair of first coupling parts 210 and second coupling parts 220 can be operably coupled together or decoupled apart, thereby allowing the first housing component 21 and the second housing component 22 to be assembled together or separated from each other. In other words, this application can assemble the first housing component 21 and the second housing component 22 together simply by operating the first coupling parts 210 and the second coupling parts 220 on the first housing component 21 and the second housing component 22, without the need for other tools or fasteners (such as screws, bolts, etc.) for fixing, making assembly relatively simple. At the same time, since the cat compartment 2 can be disassembled into the first housing component 21 and the second housing component 22, the volume of the cat compartment 2 packaging can be greatly reduced, which is beneficial for transportation. The first coupling parts 210 and the second coupling parts 220 can be assembled by snap-fitting, screwing, etc.

[0069] Please refer to the following: Figures 12-15The first housing component 21 and the second housing component 22 are assembled together by a snap-fit ​​mechanism. The first coupling portion 210 includes a pull tab 211 fixed to the first housing component 21. The pull tab 211 is generally arc-shaped, and its inner side 212 is fixed to the first housing component 21 by a fastener 213, which can be a screw, bolt, etc. The pull tab 211 includes a rectangular bottom side 214, three fixing portions 215 spaced apart and arranged side-by-side along the length of the bottom side 214, a mating opening 216 formed between two adjacent fixing portions 215, and two engaging walls 217 extending upward from one end of the bottom side 214 and located between two adjacent fixing portions 215. One end of the fixing portion 215 is connected to the first housing component 21. The engaging wall 217 is located at the other end of the fixing portion 215 away from the first housing component 21. The two engaging walls 217, the three fixing parts 215, and the bottom side 214 form two latches 218. The engaging wall 217 is also provided with a latching groove 2180 on the side facing the first housing component 21.

[0070] Please refer to the following: Figures 16-17 The second coupling portion 220 is provided corresponding to the first coupling portion 210. The second coupling portion 220 includes a latch 221. The latch 211 engages with the latch 22 to couple the first housing component 21 and the second housing component 22. Specifically, the second coupling portion 220 also includes a mounting portion 222 and a pivot portion 223. The mounting portion 222 is fixed to the second housing component 22. The pivot portion 223 pivotally connects the latch 221 to the mounting portion 222, allowing the latch 221 to rotate relative to the second housing component 22. The second coupling portion 220 engages with the engaging wall 217 via the latch 221, thereby assembling the first housing component 21 and the second housing component 22 together with the first coupling portion 210.

[0071] The latch 221 includes two opposing sidewalls 2211 and a locking portion 2212 connected between the two sidewalls 2211 and located away from the second housing component 22. The locking portion 2212 protrudes towards the first housing component 21 with two spaced-apart hooks 2213, that is, the latch protrudes towards the first housing component with two spaced-apart hooks to lock with the pull tab 211.

[0072] The mounting portion 222 has two opposing lugs 2221. The pivot portion 223 includes two spaced-apart first pivot portions 2231 and second pivot portions 2232. The first pivot portion 2231 is connected between the two lugs 2221 via a first pivot shaft 2233, thereby rotatably connecting the first pivot shaft 2233 to the mounting portion 222. The second pivot portion 2232 is connected between the two side walls 2211 via a second pivot shaft 2234, thereby rotatably connecting the second pivot portion 2232 to the side walls 2211, thus rotatably mounting the latch 221 to the second housing component 22. When the latch 221 rotates downwards to be parallel to the cat compartment 2, the latch inserts two hooks 2213 into two slots 2180 through two slots 218, so that each hook 2213 is inserted into the corresponding slot 2180, thereby locking the latch 221 into the two engagement walls 217, thus coupling the second coupling part 220 with the first coupling part 210. When the latch 221 rotates upwards, the two hooks 2213 can disengage from the two slots 2180, thereby decoupling the second coupling part 220 from the first coupling part 210.

[0073] In this embodiment, the cat compartment 2 also includes a rack 230 and an assembly portion 224. The rack 230 is disposed on the first housing component 21 and located at the junction 23 of the first housing component 21 and the second housing component 22, for meshing with the drive device 6. The rack 230 extends from one side of the opening 24 along the junction 23. The length of the rack 230 is determined according to the rolling amplitude of the cat compartment 2. The assembly portion 224 is disposed on the second housing component 22 and is a bearing. The cat compartment 2 is rotatably connected to the base 1 via the assembly portion 224. In this application, the opening 24 is located at the junction 23 of the first housing component 21 and the second housing component 22.

[0074] The litter box 100 also includes a partition 27 disposed in the compartment 26 and a screen 28 disposed adjacent to the partition 27. The screen 28 is pivotally connected to the compartment 27. A litter collection space 29 is formed between the partition 27 and the interior of the litter box 2, and includes an integrally formed first partition 271 and a second partition 272. The first partition 271 includes a vertical plane 2711 facing away from the litter collection space 29. The second partition 272 includes a first curved surface 2721 protruding into the litter collection space 29. The screen 28 is disposed adjacent to the second partition 272 and includes a second curved surface 281 protruding away from the litter collection space 29. When the litter box 2 is rolled, the partition 27 and the screen 28 are used to separate the litter and excrement, and the excrement rolls along the partition 27 to the opening 24 and is discharged from the litter box 2 from the opening 24.

[0075] In this embodiment, the base 1 includes a mounting shell 11, a support shaft 12 detachably fixed to the mounting shell 11, several support legs 13, and a waste collection chamber 3. The support shaft 12 extends from the mounting shell 1 upwards from the mounting shell 11. The several support legs 13 are located below the mounting shell 11 and are used to support the mounting shell 11. Specifically, the mounting shell 11 has a mounting shell opening 112 on the side facing the support legs. The mounting shell opening 112 allows the cat pouch 2 to connect with the waste collection chamber 3 when the opening 24 is rotated to face the waste collection chamber 3, so that excrement can fall into the waste collection chamber 3. The mounting shell 11 has an arc-shaped mounting groove 110, the shape of which is adapted to the shape of the cat pouch 2, for partially accommodating the cat pouch 2. The end of the support shaft 12 away from the mounting shell 11 is rotatably connected to the assembly part 224, thereby rotatably connecting the cat pouch 2 to the base 1 and supporting the cat pouch 2. The bottom of the mounting shell 11 has two opposing sliding grooves 111. The waste collection chamber 3 is located below the mounting shell 11 and at the position where the opening 24 passes, for collecting excrement discharged from the opening 24. Optionally, the waste collection chamber 3 is located in the middle position below the mounting shell 11. The waste collection chamber 3 has two corresponding slide rails 31 on the side facing the base. The waste collection chamber 3 can be pulled out of the mounting shell or installed by means of the slide rails 31 and the slide groove 111. When the cat hopper 2 rolls, the excrement rotates along the partition 27 to the opening 24 and is discharged from the opening 24 into the waste collection chamber 3.

[0076] The drive unit 6 is mounted on the mounting housing 11. The drive unit 6 includes a motor 61 and a drive gear 62. A portion of the drive gear 62 extends out of the mounting housing 11, that is, a portion of the drive gear 62 extends out of the base 1 and is connected to the motor 61. The drive gear 62 also meshes with a rack 230. When the motor 61 is working, the drive gear 62 is driven by the motor 61 and drives the cat compartment 2 to rotate via the rack 230. In this application, the drive unit 6 also includes a motor bracket 64 for supporting the motor 61, a motor housing 63 located outside the motor 61, a motor bearing for connecting the motor 61 to the drive gear 62, and a motor shaft washer 65, a retaining ring 66, and a motor shaft sleeve 67 located on the motor bearing.

[0077] The litter box 100 also includes auxiliary rollers 5. The auxiliary rollers 5 assist the rolling of the litter box 2 when driven by the drive device 6, thereby improving the stability of the litter box 2's rolling and reducing damage caused by friction during rolling. Taking one auxiliary roller 5 as an example, the auxiliary roller 5 includes a first roller bracket 51, a second roller bracket 52, and a roller 53. The first roller bracket 51 and the second roller bracket 52 are assembled together to form a rolling space accommodating the roller 53. Optionally, two auxiliary rollers 5 are respectively provided on the outer wall of the first housing component 21 and the outer wall of the second housing component 21, and each auxiliary roller 5 is close to the base 1.

[0078] In this embodiment, the litter box 100 also includes an arc-shaped top cover 4. The shape of the top cover 4 is adapted to the joint 23 of the cat compartment 2. The two ends of the top cover 4 are respectively fixed to the base 1 and are opposite to the mounting shell 11, thereby forming an installation space together with the mounting shell 11 to accommodate the cat compartment 2, and exposing the opposite sides of the first shell component 21 and the second shell component 22. The top cover 4 also covers the opening 24 to cover the joint 23 of the first shell component 21 and the second shell component 22 and prevent the opening 24 from being exposed.
