Cats have become the first choice of pets because of their own attributes. Raising cats can bring great satisfaction to the owner, but at the same time, raising cats also has many troubles, especially the need to clean up the cat's excrement every day, which brings a lot of inconvenience to many cat owners.

[0003] The traditional way to clean cat feces: After the cat has defecated in the litter box, the cat owner needs to use a shovel to find the cat feces in the litter and scoop them out and throw them away. In this process, the cat owner needs to come into close contact with the cat feces many times every day and endure the stench of cat feces to complete the shoveling action.

[0004] Then, automatic cat litter boxes appeared on the market. They separated cat litter and cat feces by rotating a motor, eliminating the need for manual shoveling of feces, which brought great convenience to cat owners. However, the feces collection bin of current cat litter machines is generally set at the base, which results in the distance between the opening of the cat litter machine cabin and the ground being too high, making it inconvenient for cats to enter the cabin. Moreover, there is a clamping structure inside the cabin, which poses a safety hazard and the risk of trapping cats. Utility Model Content

[0040] As people's living standards improve, they begin to pursue more spiritual life, and many of them choose to raise pets to add color to their lives. Cats have become the first choice of pets because of their own attributes. Raising cats can bring great satisfaction to the owner, but at the same time, raising cats also has many troubles, especially the need to clean up the cat's excrement every day, which brings a lot of inconvenience to many cat owners.

[0041] The traditional way to clean cat feces: After the cat has defecated in the litter box, the cat owner needs to use a shovel to find the cat feces in the litter and scoop them out and throw them away. In this process, the cat owner needs to come into close contact with the cat feces many times every day and endure the stench of cat feces to complete the shoveling action.

[0042] Then, automatic cat litter boxes appeared on the market. They separated cat litter and cat feces by rotating a motor, eliminating the need for manual shoveling of feces, which brought great convenience to cat owners. However, the feces collection bin of current cat litter machines is generally set at the base, which results in the distance between the opening of the cat litter machine cabin and the ground being too high, making it inconvenient for cats to enter the cabin. Moreover, there is a clamping structure inside the cabin, which poses a safety hazard and the risk of trapping cats.

[0043] The cat litter machine provided by the embodiment of the utility model is now described.

[0044] Please also read Figures 1 to 4 The cat litter machine includes a base 10, a driver and a drum assembly 20.

[0045] The base 10 is used to be placed on the ground to support and stabilize the entire cat litter machine. The drum assembly 20 is arranged on the base 10 , and the base 10 can support the drum assembly 20 so that the drum assembly 20 can rotate on the base 10 .

[0046] The driver is used to drive the drum assembly 20 to rotate, and the driver can output a rotational motion, thereby rotating the drum assembly 20. The rotation of the drum assembly 20 is generally self-rotation, that is, the rotation axis of the drum assembly 20 is the central axis, and the position of the drum assembly 20 remains unchanged during rotation, thereby maintaining the stability of the cat litter machine during movement.

[0047] The drum assembly 20 is disposed on the base 10 and supported by the base 10. The drum assembly 20 includes a drum body 21 and a partition assembly 22. The drum body 21 has a receiving cavity formed therein. The partition assembly 22 divides the receiving cavity into a first cavity 201 and a second cavity 202.

[0048] The first cavity 201 has the following functions: first, it is an area for pets to enter and urinate and defecate; second, it is used to hold cat litter. After the pet defecates, the cat litter will wrap the excrement to form a ball-like object. In the following text, for the convenience of description and understanding, the ball-like object is still referred to as excrement. In other words, when the pet needs to defecate, it enters the first cavity 201 of the accommodating cavity. At this time, the cat litter is located inside the first cavity 201 and is located in the lowest area of ​​the first cavity 201 under the action of gravity. By setting the partition assembly 22, the accommodating cavity can be divided into two relatively independent cavities, which can reduce the risk of pinching the cat.

[0049] The second cavity 202 has a relatively independent feces collecting bin 2022 and a litter collecting bin 2021. The feces collecting bin 2022 is used to collect excrement and cat litter that needs to be replaced. In short, it is used to collect items to be discarded. The litter collecting bin 2021 is used to collect cat litter each time feces are collected, and the cat litter is recycled.

[0050] The partition assembly 22 includes a partition body 222, a sand guide plate 223, a sand filter plate 221 and a sand cleaning plate 224. The partition body 222, the sand guide plate 223 and the sand filter plate 221 together separate the accommodating chamber into a first cavity 201 and a second cavity 202. The partition body 222 is arranged between the sand guide plate 223 and the sand filter plate 221. The sand filter plate 221 is provided with mesh holes so that cat litter can pass through the sand filter plate 221, but excrement cannot pass through the sand filter plate 221. The sand filter plate 221 is the cat litter entrance of the sand collection bin 2021, that is, the cat litter can enter the sand collection bin 2021 from the first cavity 201 through the sand filter plate 221. The sand guide plate 223 can move relative to the partition body 222, and the sand guide plate 223 is the excrement entrance 203 of the feces collection bin 2022. When the sand guide plate 223 moves relative to the partition body 222, the feces collection bin 2022 can be opened, that is, the first cavity 201 and the feces collection bin 2022 can be connected, that is, the excrement can enter the feces collection bin 2022 from the first cavity 201 through the sand guide plate 223. The sand cleaning plate 224 can block the sand filter plate 221 to isolate the first cavity 201 and the sand collection bin 2021, so that when the cat litter passes the position corresponding to the sand cleaning plate 224, the cat litter will not enter the sand collection bin 2021.

[0051] When the cat litter machine is in the initial state, part of the inner wall of the first cavity 201 is located at the lowest point of the accommodating cavity, and the cat litter is located here under the action of gravity. Therefore, the feces collection bin 2022 is located on the side of the drum assembly 20, which is convenient for the pet owner to open the feces collection bin 2022 and clean the excrement.

[0052] When it is necessary to collect feces, the driver drives the roller assembly 20 to rotate in the first direction, so that the sand filter plate 221 is gradually set horizontally, and the cat litter passes through the sand filter plate 221 and enters the sand collection bin 2021. Due to its large volume, the excrement still stays on the sand filter plate 221. The roller assembly 20 continues to rotate in the first direction, and the sand guide plate 223 moves to gradually tend to be horizontal or horizontal, and the excrement pushes the sand guide plate 223 away and enters the feces collection bin 2022. Then the driver drives the roller assembly 20 to rotate in the second direction until the cat litter machine returns to the initial state. At this time, the cat litter returns from the sand collection bin 2021 through the sand leakage plate to the first cavity 201, waiting for the next defecation of the pet. Among them, the second direction is opposite to the first direction, for example, the first direction is clockwise and the second direction is counterclockwise.

[0053] When the cat litter needs to be replaced, the sand cleaning plate 224 blocks the sand filtering plate 221, and the driver drives the roller assembly 20 to rotate in the first direction. The sand guide plate 223 moves until it gradually tends to be horizontal or is horizontal, and the cat litter pushes the sand guide plate 223 and enters the feces collecting bin 2022. Then the driver drives the roller assembly 20 to rotate in the second direction until the cat litter machine returns to its initial state, and the pet owner puts new cat litter in the first cavity 201.

[0054] The feces collection bin 2022 can be cleaned regularly, or after each feces collection, and can be cleaned by replacing the garbage bag or dumping it.

[0055] The cat litter machine in the above embodiment includes a base 10, a driver and a drum assembly 20. The drum assembly 20 includes a drum body 21 and a partition assembly 22. The partition assembly 22 divides the accommodating cavity in the drum body 21 into a first cavity 201 and a second cavity 202. The first cavity 201 is for pets such as cats to enter. The second cavity 202 has a feces collection bin 2022 and a sand collection bin 2021 that are separated and arranged. The partition assembly 22 includes a partition body 222, a sand guide plate 223, a sand filter plate 221 and a sand cleaning plate 224. The sand guide plate 223 is an excrement inlet 203 of the feces collection bin 2022, and the sand filter plate 221 is a cat litter inlet of the sand collection bin 2021. When the pet defecates, the cat litter is located at the bottom of the first cavity 201. After the pet defecates, when the excrement needs to be cleaned, the driver drives the roller assembly 20 to rotate in the first direction. When the sand filter plate 221 rotates to close to the bottom, the cat litter passes through the sand filter plate 221 and enters the sand collecting bin 2021. The excrement stays on the sand filter plate 221 due to its large volume, so that the cat litter and the excrement can be separated. After the excrement is separated from the cat litter, the roller assembly 20 continues to rotate, and the excrement slides along the surface of the sand filter plate 221 and the partition body 222 to the sand guide plate 223, and the sand guide plate 223 is pushed to make the excrement enter the excrement collecting bin 2022; then the driver drives the roller assembly 20 to rotate in the second direction, so that the partition assembly 22 returns to its initial position, and the cat litter returns to the first cavity 201 under the action of gravity. When the cat litter needs to be replaced, the sand cleaning plate 224 blocks the sand filter plate 221, and the driver drives the drum assembly 20 to rotate in the first direction. The cat litter slides along the surface of the sand cleaning plate 224 and the partition body 222 to the sand guide plate 223, and the sand guide plate 223 is pushed, and the cat litter enters the feces collection bin 2022. The cat litter machine provided by the utility model has a feces collection bin 2022 located on the side of the drum assembly 20 when it is in the initial position, so that the height of the base 10 can be reduced, making it easier for pets to enter the interior of the drum assembly 20, and the partition assembly 22 divides the accommodating chamber into a first cavity 201 and a second cavity 202, and there is no clamping structure inside the accommodating chamber, which can reduce the risk of cats being clamped. In addition, by setting the sand cleaning plate 224, the cat litter can be automatically transferred to the feces collection bin 2022, without the need to manually replace the cat litter.

[0056] In some embodiments of the present invention, please refer to Figure 5 and Figure 6The sand cleaning plate 224 is detachably connected to the sand filter plate 221. The pet owner can install the sand cleaning plate 224 on the sand filter plate 221 or remove the sand cleaning plate 224 from the sand filter plate 221 according to different working conditions. Specifically, when feces need to be collected, that is, when excrement and cat litter need to be separated, the sand cleaning plate 224 is not installed on the sand filter plate 221, and the cat litter passes through the sand filter plate 221 to achieve the separation of excrement and cat litter. When the cat litter needs to be replaced, the sand cleaning plate 224 is installed on the sand filter plate 221. When the drum assembly 20 rotates, the cat litter will not enter the sand collection bin 2021 through the sand filter plate 221, but directly enter the feces collection bin 2022.

[0057] In some embodiments of the present invention, please refer to Figure 5 and Figure 6 The sand filter plate 221 has a first concavoconvex portion, and the sand cleaning plate 224 has a second concavoconvex portion, and the first concavoconvex portion and the second concavoconvex portion are engaged with each other. The first concavoconvex portion is a concave structure, or a convex structure, or includes both a concave structure and a convex structure, and the second concavoconvex portion is a concave structure, or a convex structure, or includes both a concave structure and a convex structure.

[0058] Through the cooperation between the first concave-convex part and the second concave-convex part, the sand cleaning plate 224 can be clamped on the sand filtering plate 221, so as to realize the detachable connection between the sand cleaning plate 224 and the sand filtering plate 221. Moreover, when the sand cleaning plate 224 is disassembled and assembled, there is no need to use installation and disassembly tools, and it can be directly installed manually.

[0059] In some embodiments, see Figure 5 and Figure 6One of the first concavoconvex part and the second concavoconvex part is the rotating shaft part 2211, and the other is the shaft hole part 2242, so that the sand cleaning plate 224 can rotate relative to the sand filtering plate 221. This embodiment includes the following two cases: the first concavoconvex part is the rotating shaft part 2211, and the second concavoconvex part is the shaft hole part 2242; or the first concavoconvex part is the shaft hole part 2242, and the second concavoconvex part is the rotating shaft part 2211. When the first concavoconvex part and the second concavoconvex part are mutually engaged, the rotating shaft part 2211 and the shaft hole part 2242 are coaxially arranged, and the cross sections of the rotating shaft part 2211 and the shaft hole part 2242 are both circular, so that the sand cleaning plate 224 can rotate relative to the sand filtering plate 221. In this way, when installing the sand cleaning plate 224, the sand cleaning plate 224 can be placed to form a certain angle with the sand filtering plate 221, and the first concavo-convex part and the second concavo-convex part are opposite, and the hand can be inserted between the sand cleaning plate 224 and the sand filtering plate 221 to facilitate the application of force, so that the first concavo-convex part and the second concavo-convex part are mutually engaged, and after the engagement is completed, the sand cleaning plate 224 is rotated relative to the sand filtering plate 221 to cover the sand filtering plate 221. When disassembling the sand cleaning plate 224, the sand cleaning plate 224 can also be rotated relative to the sand filtering plate 221 to form a certain angle between the two, so that the pet owner can apply force to separate the first concavo-convex part and the second concavo-convex part from each other.

[0060] Optionally, the number of the first concavo-convex portion and the number of the second concavo-convex portion are both two, and both are arranged on one side of the sand cleaning plate 224 close to the partition body 222, so that the connection between the sand cleaning plate 224 and the sand filtering plate 221 is more stable.

[0061] Optionally, a handle 2241 for installation is provided on the side of the sand cleaning plate 224 facing away from the sand filtering plate 221. The handle 2241 can be understood as a raised structure protruding from the surface of the sand cleaning plate 224, which is convenient for the pet owner to hold the sand cleaning plate 224 for installation or removal.

[0062] The handle portion 2241 may be a structure such as a raised rib protruding from the surface of the sand cleaning plate 224 . The number of the handle portions 2241 may be one or more, and the specific number and distribution thereof are not limited herein.

When the cat litter machine is in the initial state, the sand guide plate 223, the partition body 222, and the sand filter plate 221 are arranged in order from high to low. The side of the sand filter plate 221 close to the partition body 222 is the top side of the sand filter plate 221, that is, the top side of the sand filter plate 221 is rotatably connected to the partition body 222. At the same time, a stopper 215 is provided on the inner wall of the drum body 21, and the stopper 215 is used to stop the sand filter plate 221, that is, to limit the rotation of the sand filter plate 221. Since the stopper 215 is provided on the side of the sand filter plate 221 facing the sand collecting bin 2021, that is to say, the stopper 215 is used to stop the movement of the sand filter plate 221 toward the inside of the sand collecting bin 2021, the sand filter plate 221 can only rotate in a direction away from the sand collecting bin 2021.

[0068] By setting the sand filter plate 221 to be rotatably connected to the partition body 222 and providing the stopper 215 on the drum body 21, the sand filter plate 221 can only rotate in the direction away from the sand collecting bin 2021. In this way, when collecting feces, the sand filter plate 221 is stably maintained at the edge of the sand collecting bin 2021, and will not affect the feces collection and sand filtering. After the feces collection is completed, the sand filter plate 221 can be directly manually rotated to open the sand collecting bin 2021, so that the cat litter can quickly fall back to the first cavity 201, avoiding excessive cat litter remaining in the sand collecting bin 2021.

[0069] In some embodiments of the present invention, please refer to Figure 5 , the side of the sand guide plate 223 away from the partition body 222 is rotatably connected to the drum body 21. When the cat litter machine is in the initial state, the sand guide plate 223, the partition body 222, and the sand filter plate 221 are arranged in order from high to low, and the side of the sand guide plate 223 away from the partition body 222 is the top side of the sand guide plate 223, that is, the top of the sand guide plate 223 is rotatably connected to the drum body 21. In this way, when the excrement moves to the sand guide plate 223, the sand guide plate 223 can be directly pushed close to the side of the partition body 222, so that the excrement enters the feces collection bin 2022 as soon as possible.

[0070] In some embodiments of the present invention, please refer to Figure 5 The surface composed of the side of the sand filter plate 221 facing the first cavity 201, the side of the partition body 222 facing the first cavity 201, and the side of the sand guide plate 223 facing the first cavity 201 is smoothly arranged. The surface composed can be called the first surface. The first surface is one of the inner walls of the first cavity 201, and the other inner walls of the first cavity 201 are partial inner walls of the drum body 21.

[0071] By smoothing the first surface, part of the inner wall of the first cavity 201 is also smooth, and the remaining inner wall of the first cavity 201 (part of the inner wall of the drum body 21) is also usually smooth, so that the pet will not be pinched or scratched by the inner wall of the first cavity 201 when inside the first cavity 201, thereby protecting the pet.

[0072] In some embodiments, the side of the sand filter plate 221 facing the first cavity 201, the side of the partition body 222 facing the first cavity 201, and the side of the sand guide plate 223 facing the first cavity 201 are flat or curved surfaces, as long as they are smoothly arranged.

[0073] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 The drum assembly 20 further includes a trash can 226, the interior of which is the excrement collection bin 2022. The trash can 226 can be covered with a trash bag or can be used directly. The side of the partition body 222 facing the trash can 226 and the side of the drum body 21 facing the trash can 226 form a trash cavity. The trash can 226 is arranged inside the trash cavity and can be removed from the trash cavity, making it convenient for pet owners to clean up excrement.

[0074] In some embodiments, the drum assembly 20 further includes a partition plate 225 disposed in the second cavity 202, and the partition plate 225 is used to separate the second cavity 202 into a feces collecting bin 2022 and a sand collecting bin 2021, which can also be understood as being separated into a garbage cavity and a sand collecting bin 2021. One side of the partition plate 225 is connected to the partition body 222, and the other side of the partition plate 225 extends to the inner wall of the drum body 21.

[0075] Optionally, the partition plate 225 and the partition body 222 are integrally formed, which can reduce the number of parts of the drum assembly 20, making the installation of the drum assembly 20 simpler and the internal structure layout thereof simpler.

[0076] In some embodiments of the present invention, the gap between the drum body 21 and the base 10 is less than 5 mm, such as 4 mm, 3 mm, etc. The gap between the drum body 21 and the base 10 can be understood as the minimum gap between the drum body 21 and the base 10. When the gap between the drum body 21 and the base 10 is too large, the hair or limbs of the pet are easily caught between the drum body 21 and the base 10, which poses a risk of pinching the cat. By setting the gap between the drum body 21 and the base 10 to be less than 5 mm, the risk of pinching the cat can be reduced.

[0077] In some embodiments of the present invention, please refer to Figure 1 The base 10 is provided with a gravity sensor 12 for detecting the weight change of the drum assembly 20. The weight change of the drum assembly 20 does not refer to the weight change of the drum assembly 20 itself, but refers to the change in the total weight of the drum assembly 20 and the objects contained therein. For example, the weight change of cat litter will cause the weight change of the drum assembly 20, and whether there is a pet in the drum assembly 20 will also cause the weight change of the drum assembly 20.

[0078] By setting the gravity sensor 12, it is possible to detect whether a pet enters the drum assembly 20. If a pet is detected to have entered, the rotating drum assembly 20 can be stopped to prevent the cat from being pinched.

[0079] In some embodiments of the present invention, the corners of the drum body 21 are provided with rounded structures to make the surface of the drum body 21 smooth and avoid scratching the pet.

[0080] In some embodiments of the present invention, please refer to Figures 2 to 4 The drum body 21 includes a first cylinder 211, a second cylinder 212 and a cover 213. The first cylinder 211 has a pet entrance for pets to enter, and the cover 213 is set at the exit of the feces collection bin 2022; the partition body 222 extends along the inner wall of the first cylinder 211 and / or the second cylinder 212 to form an extension 2221, and the extension 2221 is fixed to the first cylinder 211 and / or the second cylinder 212. The first cylinder 211, the second cylinder 212 and the cover 213 surround the drum body 21 and form a accommodating cavity. When the pet needs to defecate, it enters the first cavity 201 from the pet entrance of the first cylinder 211. When the feces collection bin 2022 needs to be cleaned, the cover 213 is opened to expose the feces collection bin 2022, so as to facilitate the cleaning of the collected excrement. The extension portion 2221 is integrally formed with the partition body 222 , and the extension portion 2221 can be fixed to the inner wall of the first cylinder 211 and / or the second cylinder 212 . The partition body 222 can be fixed by fixing the extension portion 2221 , thereby facilitating the installation of the partition body 222 .

[0081] By configuring the drum body 21 to be connected by a first cylinder 211, a second cylinder 212, and a cover 213, the drum body 21 is easier to process and easier to install structures such as the partition assembly 22. By configuring the extension 2221, the partition assembly 22 can fit the inner wall of the drum body 21 to further reduce the risk of cat pinching, and the partition assembly 22 can be more easily installed on the inner wall of the drum body 21.

[0082] In some embodiments, the extension part 2221 fits with the inner wall of the drum body 21, so that the extension part 2221 is more easily fixed to the drum body 21. Specifically, the extension part 2221 can fit with the inner wall of the first cylinder 211, or the extension part 2221 fits with the inner wall of the second cylinder 212, or the extension part 2221 fits with the inner walls of the first cylinder 211 and the second cylinder 212.

[0083] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 The first cylinder 211 has a first toothed portion 2141 on one side, and the second cylinder 212 has a second toothed portion 2142 on one side. The first toothed portion 2141 and the second toothed portion 2142 together form an annular toothed structure 214, and the gears and other structures mesh with the toothed structure 214, so as to control the rotation of the drum assembly 20. The first toothed portion 2141 and the second toothed portion 2142 are both semi-arc-shaped and are not closed structures. After the first cylinder 211 and the second cylinder 212 are connected to each other, the first toothed portion 2141 and the second toothed portion 2142 form a complete ring, so as to be able to perform meshing transmission.

[0084] By configuring the tooth-shaped structure 214 to include the first tooth-shaped portion 2141 and the second tooth-shaped portion 2142 which are separated from each other, the processing difficulty of the tooth-shaped structure 214 is reduced, thereby reducing the processing cost.

[0085] In some embodiments, the tooth structure 214 formed by the first tooth portion 2141 and the second tooth portion 2142 is located on the outer side of the drum body 21, and the tooth structure 214 is an external tooth structure 214, which facilitates meshing transmission of the tooth structure 214 through other gears.

[0086] In other embodiments, the tooth-shaped structure 214 may be independently disposed on one side of the first cylinder 211 , or independently disposed on one side of the second cylinder 212 .

[0087] In some embodiments of the present invention, the cat litter machine further comprises a driving gear, which is driven to rotate by a driver, and the driving gear is meshed with the toothed structure 214. Thus, the driving gear can be driven by the driver to drive the toothed structure 214 to rotate, thereby driving the drum assembly 20 to rotate.

[0088] In some embodiments, the driver is an electric motor, etc.

[0089] In some embodiments, the driver and the driving gear are disposed inside the base 10 .

[0090] In some embodiments of the present invention, please refer to Figure 7 , a plurality of roller assemblies 11 for supporting the roller assembly 20 are arranged on the side of the base 10 facing the roller assembly 20. It can be understood that a plurality of roller assemblies 11 are arranged on the top surface of the base 10, and the roller assemblies 11 are used to support the roller assembly 20, and the rotation axis of the roller assembly 11 is parallel to the rotation axis of the roller assembly 20, so as to guide the rotation of the roller assembly 20 and reduce the friction between the base 10 and the roller assembly 20.

[0091] By arranging the roller assembly 11 on the base 10, not only the drum assembly 20 can be supported, but also the drum assembly 20 can be rotationally guided, thereby reducing the friction between the base 10 and the drum assembly 20. There is no need to arrange bearings, thereby reducing the parts cost of the cat litter machine.

[0092] In some embodiments, there are four drum assemblies 20 , which are respectively disposed at four corners of the base 10 to form a more stable support for the drum assembly 20 .

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
