Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, specifically relating to a closed three-layer cat litter box. Background Technology

[0002] In the current pet supplies market, most cat litter boxes have a relatively simple shape, mainly rectangular, round, or oval. This single shape may not be suitable for all cat sizes, especially for cats that are large or small, which may feel uncomfortable or have difficulty getting in and out. In addition, most existing cat litter boxes use a top opening design. While this design makes it convenient for cats to get in and out, it also makes it easy for cats to bring the litter out after use. When burying feces, the litter can also easily splash out of the box, increasing the difficulty of cleaning and polluting the home environment.

[0003] Secondly, most existing cat litter boxes are made of plastic. After long-term use, the plastic surface is easily scratched by the cat litter. These scratches not only affect the appearance, but also easily trap dirt and grime, making them difficult to clean thoroughly. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 1 to 4 The enclosed three-layer cat litter box shown includes a litter bin 1, a first extension layer 2 at the top of the litter bin 1, a first semi-circular groove 21 at the bottom front side of the first extension layer 2, a second extension layer 3 installed above the first extension layer 2, a second semi-circular groove 31 at the top front side of the second extension layer 3, and a rotating door 4 rotatably connected between the top of the inner walls of the first semi-circular groove 21; locking grooves 5 on both the left and right sides of the first extension layer 2, with first locking blocks 6 inside the locking grooves 5; locking blocks 7 on the left and right sides at the bottom of the second extension layer 3; and a semi-open groove 8 at the top of the second extension layer 3. A hinged cover 9 is hinged to the left side of the open slot 8; a second locking block 10 is rotatably provided on the right side of the hinged cover 9, and a slot 11 is provided at the bottom of the second locking block 10; a locking rod 12 is provided at the bottom right side of the second extension layer 3; an additional outlet 13 is provided on the rear side of the top of the hinged cover 9; a storage slot 14 is provided on the front side of the top of the hinged cover 9, and an exhaust plate 141 is slidably installed in the storage slot 14; multiple exhaust holes 142 are provided at the bottom of both the exhaust plate 141 and the storage slot 14; the top of the hinged cover 9 is evenly provided with concave and convex textures 15; the shape of the revolving door 4 is consistent with the first semicircular slot 21 and the second semicircular slot 31.

[0030] This invention employs a three-layer structure, with the dimensions of the first and second layer 2 decreasing sequentially to form a stepped space to accommodate cats of different sizes. The entire invention features a closed design, allowing cats to enter and exit only through a rotating door 4 and an additional exit 13, effectively reducing litter spillage and scattering during use, preventing litter from being carried outside the litter box, and reducing the frequency and difficulty of cleaning the floor. The second layer 3 is a detachable structure, connected by a locking groove 5 and a locking block 7, allowing users to install or remove it as needed for thorough cleaning and maintenance of the litter box. The litter bin 1 in this invention is made of stainless steel. The surface is smooth, making it difficult for cat litter, urine, and other dirt to remain, and it also does not easily absorb odors and stains, making it easy to clean. This utility model has a storage groove 14 on the front side of the top of the flip cover 9, which can hold odor-removing items such as deodorizing charcoal bags. At the same time, multiple vent holes 142 are provided on the exhaust plate 141 and the bottom of the storage groove 14, so that the air inside the cat litter box can fully contact the deodorizing charcoal bags, effectively absorb and decompose odors, and keep the air inside the cat litter box fresh. The top of the flip cover 9 in this utility model has evenly distributed concave and convex textures 15, which increases friction and prevents the cat from slipping and falling when leaving from the top outlet. At the same time, it can also catch the cat litter carried between the cat's paws, reducing the possibility of cat litter being carried out of the box.

[0031] Example 2

[0032] like Figures 1 to 4 The illustrated closed three-layer cat litter box includes a litter bin 1 for holding cat litter. The litter bin 1 can be made of either stainless steel or plastic. Considering that stainless steel can be used for a long time without deformation or wear; its smooth surface makes it less likely to retain cat litter, urine, and other dirt, and it does not easily absorb odors and stains, thus making it easier to clean; in addition, cat litter boxes made of stainless steel are usually heavier, making them more stable and less likely to be kicked over or moved by cats, which is more conducive to the cleanliness and orderliness of furniture; and the cat litter box can be recycled and reused when it is no longer in use; based on the above characteristics, this embodiment uses stainless steel to prepare the base of the cat litter box.

[0033] However, considering that some larger cats may require moving the litter box, therefore... Figures 5-6 As shown, a cardboard shell can be used as a protective layer on the outside of the litter box. The cardboard shell needs to be customized according to the specific size of the litter box to ensure that it fits tightly to the litter box. This will not hinder the normal use of the litter box, but will provide sufficient protection and cushioning, effectively reducing the noise when the litter box is moved, and protecting the bottom of the litter box 1 from wear and tear and the sides from dirt.

[0034] The litter box 1 has a first raised layer 2 on top, the actual area of ​​which is slightly smaller than that of the litter box 1. At the same time, a second raised layer 3 is installed above the first raised layer 2, the actual area of ​​which is slightly smaller than that of the first raised layer 2. This forms a three-layer enclosed litter box. Compared with conventional single-layer litter boxes, the raised design can not only accommodate a larger capacity and space to accommodate cats of different sizes, but also reduce the splashing and scattering of litter when cats use the litter box, preventing cats from taking litter out of the litter box when entering and exiting, effectively reducing the frequency and difficulty of cleaning the floor and keeping the furniture environment clean.

[0035] The first layer 2 has a first semi-circular groove 21 at the bottom front side, and the second layer 3 has a second semi-circular groove 31 at the top front side. The second semi-circular groove 31 and the first semi-circular groove 21 form an elliptical space. A rotating door 4 is rotatably connected between the top of the inner wall of the first semi-circular groove 21. The shape of the rotating door 4 is consistent with the elliptical space. Therefore, the cat can enter the litter box 1 through the first semi-circular groove 21 after pushing the rotating door 4 to rotate. After entering, the rotating door 4 will automatically rotate and reset. After the cat has finished using the litter box 1, it can push the rotating door 4 again from the inside of the litter box 1 to rotate and move out of the litter box 1 through the first semi-circular groove 21.

[0036] The second layer 3 has a semi-open slot 8 at the top, meaning the top and right side are open. A hinged cover 9 is then attached to the left side of the semi-open slot 8. The cover 9 is L-shaped to fit the shape of the semi-open slot 8. In normal state, the cover 9 will be locked in the semi-open slot 8, sealing the entire litter box. When the user needs to dispose of the litter inside, the cover 9 can be opened to expose the entire litter box, making it easy to scoop out the litter. Specifically, a second locking block 10 is provided on the right side of the flip cover 9. The bottom of the second locking block 10 has a circular opening slot 11. Correspondingly, a locking rod 12 is provided at the bottom right side of the second extended layer 3. In the normal state, the second locking block 10 is in a vertical position, and the slot 11 will be engaged in the locking rod 12, which indirectly fixes the flip cover 9. When it is necessary to open the flip cover 9, the second locking block 10 is rotated to a horizontal position, which causes the slot 11 to no longer engage in the locking rod 12, and thus the flip cover 9 is no longer fixed on the first extended layer 2, so the flip cover 9 can be opened.

[0037] Example 3

[0038] Furthermore, the second extension layer 3 is detachable. It can be used selectively when environmental conditions permit or other needs permit. Locking grooves 5 are recessed on both the left and right sides of the first extension layer 2. A first locking block 6 is provided at the top of the locking groove 5. Correspondingly, locking blocks 7 are provided on both the left and right sides of the bottom of the inner wall of the second extension layer 3. The user can press the second extension layer 3 to move the locking blocks 7 down along the locking groove 5 until the locking blocks 7 are locked under the first locking blocks 6, thus completing the installation of the second extension layer 3.

[0039] Example 4

[0040] Furthermore, considering the needs of some cats, an additional outlet 13 is provided on the rear side of the top of the lid 9. After using the litter box, cats can freely choose to leave quickly from the top or side outlet, reducing the risk of being disturbed by other pets or humans. Based on this, the top of the lid 9 is evenly textured with grooves 15 to increase friction. This not only prevents cats from slipping and falling when leaving from the top outlet, but also catches the litter between the cat's paws, reducing the possibility of it being taken out of the box and keeping the home environment clean.

[0041] Example 5

[0042] Furthermore, considering that this embodiment is in a sealed state with high frequency during normal use, which can easily lead to the accumulation of odors over time, a storage compartment 14 is also provided on the front top side. An exhaust plate 141 is slidably installed inside the storage compartment 14. Understandably, the user can pull out the exhaust plate 141, place odor-removing items such as deodorizing charcoal bags into the storage compartment 14, and then put the exhaust plate 141 back into the storage compartment 14 to prevent the cat from taking out the deodorizing charcoal bags and affecting the deodorizing effect. Both the exhaust plate 141 and the bottom of the storage compartment 14 have multiple exhaust holes 142, allowing the air inside the litter box to fully contact the deodorizing charcoal bags in the storage compartment 14, effectively absorbing and decomposing odors.

[0043] Furthermore, a litter scoop (not shown in the picture) is installed below the opening of the litter box. The scoop head is made of high-density polycarbonate material with a nano-scale frosted texture on its surface, which can effectively prevent litter from sticking and avoid scratching the litter box coating. The litter scoop is installed on the outside of the litter box through a detachable structure. The detachable structure has a built-in magnetic interface that fits seamlessly with the litter scoop. When detached, the litter scoop automatically attaches to the detachable structure, which supports quick cleaning and also prevents the tool from being lost.
