Description

Technical Field

[0001] This utility model relates to the field of pet equipment technology, specifically to a cat litter box. Background Technology

[0002] A litter box is a toilet fixture used by cats to relieve themselves. It collects cat litter and wraps up the cat feces with the litter, making it easier for people to collect and dispose of the feces using a litter scoop.

[0003] Current litter boxes consist of a base and a middle frame. Due to structural limitations, the base and middle frame are not easily folded together, resulting in a large size that affects transportation, packaging, and storage. Moreover, when in use, the middle frame is placed on top of the base. Because there is a gap between the bottom edge of the middle frame and the bottom edge of the base, and cats, based on biological instincts (such as territorial marking, information transmission, etc.), may urinate standing up, causing urine to adhere to the side wall of the litter box. The urine may flow down the side wall and leak out of the gap between the bottom edge of the middle frame and the bottom edge of the base, resulting in leakage. This is not only unhygienic but also difficult to clean. Furthermore, the litter box has a large base and a small middle frame, resulting in an excessively large base area, high litter consumption, and cramped space for the cat to move around in the middle frame, causing cats to dislike using it.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. In the description of the present utility model, unless otherwise stated, "a plurality of" means two or more, and "several" means one or more.

[0036] Example 1:

[0037] Please see Figures 1 to 3 The present invention provides a cat litter box, comprising: a base 10 and a middle frame 20.

[0038] A first opening 11 is formed at the top of the base basin 10;

[0039] The middle frame 20 is detachably connected to the base basin 10. The horizontal cross-section inside the middle frame 20 is larger than the horizontal cross-section inside the base basin 10. The bottom of the middle frame 20 is provided with a second opening 21 and a first leak-proof part 22. The second opening 21 communicates with the first opening 11. The first leak-proof part 22 is located at the edge of the second opening 21 and is arranged around the second opening 21. The first leak-proof part 22 extends downward at an angle toward the middle of the second opening 21 and extends into the base basin 10 from the first opening 11. The top of the middle frame 20 is also provided with a third opening 23.

[0040] When cat urine falls onto the inner wall of the middle frame 20 and flows down, the urine can flow directly from the first opening 11 into the bottom basin 10 along the first leak-proof part 22, and then fall from the bottom of the first leak-proof part 22 onto the cat litter located in the bottom basin 10. This prevents the urine from flowing along the middle frame 20 into the gap between the bottom of the middle frame 20 and the top of the bottom basin 10, and then leaking out to the outside of the middle frame 20 or the bottom basin 10, thus achieving the function of preventing urine leakage. The first leak-proof part 22 can also achieve a certain positioning function to prevent the middle frame 20 from swaying horizontally relative to the bottom basin 10.

[0041] In addition, the horizontal cross-section of the inner wall of the litter box 10 is relatively small, resulting in a small volume ratio. A smaller amount of cat litter is needed to fill the litter box 10 to a sufficient height, thus meeting the cat's needs and saving litter. Meanwhile, the horizontal cross-section of the inner frame 20 is relatively large, providing more space within the frame and making it easier for the cat to move around.

[0042] After the base 10 and the middle frame 20 are separated, the base 10 can be placed into the middle frame 20. Since the horizontal cross-section of the middle frame 20 is larger than the horizontal cross-section of the base 10, the base 10 is easier to stack and hide in the middle frame 20, and less likely to expose much of the structure. This allows the two to be stacked better, minimizing the volume and making it convenient for storage, transportation, and packaging.

[0043] Please see Figure 4 In some alternative embodiments, the first leak-proof part 22 includes an inclined guide part 221 and a shielding part 222. The inclined guide part 221 is arranged around the second opening 21 and extends inclined downward in the direction toward the center of the second opening 21. The shielding part 222 is connected to the bottom end of the inclined guide part 221 and extends into the basin 10 from the first opening 11. The shielding part 222 shields the gap between the inclined guide part 221 and the top of the basin 10. The cat's urine falls onto the inner wall of the middle frame 20 and flows down. Then, it is guided by the inclined guide part 221 to the shielding part 222. The urine then flows down from the shielding part 222 and drips onto the cat litter in the base 10. The shielding part 222 blocks the gap between the base 10 and the middle frame 20. If the urine is to enter the gap between the base 10 and the middle frame 20, it needs to bypass the shielding part 222 and then overcome gravity to flow backward. Therefore, it is extremely difficult for the urine to leak out of the base 10 and the middle frame 20.

[0044] In some alternative embodiments, the bottom of the middle frame 20 is provided with a first positioning part 24 arranged around the first leak-proof part 22, and a first positioning groove 25 is formed between the first positioning part 24 and the first leak-proof part 22.

[0045] A first support portion 12 is formed on the top of the base basin 10. The first support portion 12 is arranged around the first opening 11. The first support portion 12 is positioned and engaged with the first positioning groove 25, thereby preventing the middle frame 20 from swaying in the horizontal direction relative to the base basin 10, so that the connection between the middle frame 20 and the base basin 10 is stable.

[0046] In some optional embodiments, the first positioning part 24 is provided with a plurality of latching parts 26, which are arranged on at least two sides of the base 10. The latching parts 26 engage with the first support part 12, thereby confining the first support part 12 within the first positioning groove 25, thus preventing the middle frame 20 from separating from the base 10 and achieving a detachable connection between the base 10 and the middle frame 20. Of course, the detachable connection between the middle frame 20 and the base 10 is not limited to this. Those skilled in the art can also choose other suitable structures based on the teachings of this utility model. The middle frame 20 and the base 10 can also be detachably connected by a threaded structure or by an interference fit, without being limited to this example.

[0047] In some alternative embodiments, the horizontal cross-section inside the middle frame 20 gradually narrows from top to bottom, thereby facilitating the guidance of urine toward the first leak-proof part 22.

[0048] The horizontal cross-section inside the base 10 gradually decreases from top to bottom, which helps to further reduce the amount of cat litter used while maintaining sufficient cat litter height.

[0049] In this embodiment, the horizontal cross-section inside the middle frame 20 gradually decreases from top to bottom, and the horizontal cross-section inside the base 10 also gradually decreases from top to bottom. This design facilitates the storage of the base 10 into the middle frame 20 when the base 10 and the middle frame 20 are separated.

[0050] An opening 27 for easy access for a cat can be provided on the side or at the corner of the middle frame 20. The opening 27 is connected to the third opening 23.

[0051] Example 2:

[0052] Please see Figure 5 This utility model provides a cat litter box in embodiment two. The difference between the cat litter box in embodiment one and the cat litter box in embodiment one is that the opening position of the opening 27 is different. The position of the opening 27 can be designed according to actual needs, and is not limited to the one shown in the figure.

[0053] Example 3:

[0054] Please see Figures 6 to 8 This utility model provides a cat litter box in Embodiment 3. The difference between Embodiment 3 and Embodiment 1 is that, in Embodiment 3, the litter box further includes a top cover 30, which is detachably connected to the middle frame 20. The top cover 30, middle frame 20, and bottom basin 10 form a cavity 31. An inlet / outlet 311 for the cat to enter and exit the cavity 31 is provided on the top or side of the cavity 31. The top cover 30, middle frame 20, and bottom basin 10 can form a closed cavity 31, which helps reduce the escape of odor from the cavity 31 to the outside. The top cover 30 can be removed from the middle frame 20, allowing the user to install the top cover 30 according to actual needs, adapting to different usage situations.

[0055] To expand the space of cavity 31 and facilitate the movement of larger cats, in some optional embodiments, the bottom of the top cover 30 is provided with a groove 32 and a second leak-proof part 33. The groove 32 further increases the height of cavity 31 to facilitate the movement of cats. The groove 32, the middle frame 20 and the bottom basin 10 surround to form cavity 31. The bottom of the groove 32 is provided with a fourth opening 321, which communicates with the third opening 23. The second leak-proof part 33 is arranged around the fourth opening 321 and extends into the middle frame 20 from the third opening 23.

[0056] When cat urine falls onto the inner wall of the groove 32 and flows down, the urine can directly enter the middle frame 20 from the third opening 23 along the second leak-proof part 33, then fall along the inner wall of the middle frame 20 to the first leak-proof part 22, and finally fall from the bottom of the first leak-proof part 22 onto the cat litter located in the base tray 10. Thus, the second leak-proof part 33 prevents urine from entering the gap between the bottom of the top cover 30 and the top of the middle frame 20 along the inner wall of the groove 32, and the first leak-proof part 22 enters the gap between the bottom of the middle frame 20 and the top of the base tray 10 along the middle frame 20, thereby effectively preventing urine from leaking out of the cavity 31 and achieving the function of preventing urine leakage.

[0057] Please see Figure 9 In some optional embodiments, a second positioning part 34 is provided at the bottom of the top cover 30, the second positioning part 34 is arranged around the second leak-proof part 33, and a second positioning groove 34 is formed between the second positioning part 34 and the second leak-proof part 33; a second support part 28 is provided at the top of the middle frame 20, the second support part 28 is arranged around the third opening 23, and the second support part 28 is positioned and engaged with the second positioning groove 34, thereby preventing the top cover 30 from swaying in the horizontal direction relative to the middle frame 20, so that the connection between the middle frame 20 and the top cover 30 is stable.

[0058] In some optional embodiments, the middle frame 20 is provided with a plurality of fasteners 29, which are arranged on at least two sides of the middle frame 20. The fasteners 29 engage with the top cover 30 to restrict the top cover 30 to the middle frame 20, thereby achieving a detachable connection between the top cover 30 and the middle frame 20. In this embodiment, the fasteners 29 are located at the bottom of the second support portion 28 and then engage with the top of the second positioning portion 34 of the top cover 30, thereby restricting the second support portion 28 within the second positioning groove 34, thus preventing the middle frame 20 from separating from the top cover 30 and achieving a detachable connection between the top cover 30 and the middle frame 20. Of course, the detachable connection between the middle frame 20 and the top cover 30 is not limited to this. Those skilled in the art can also choose other suitable structures based on the teachings of this utility model. The middle frame 20 and the top cover 30 can also achieve a detachable connection through a threaded structure or through an interference fit, without being limited to this example.

[0059] In some alternative embodiments, the buckle 29 is provided with a handle 291, which makes it convenient for the user to pick up and put down the entire litter box. Moreover, setting the handle 291 on the buckle 29 simplifies the structure and makes it easier for the user to operate the buckle 29.

[0060] In some optional embodiments, a door 312 may be provided at the inlet / outlet 311 to conveniently cover the interior of the cavity 31, improve aesthetics, and reduce odor escape. In some optional embodiments, the inlet / outlet 311 may be formed on the middle frame 20, the top cover 30, or the base 10, and the door 312 may be movably connected to the middle frame 20, the top cover 30, or the base 10; or, the inlet / outlet 311 may also be formed between the middle frame 20 and the top cover 30, and the door 312 may be movably connected to the top cover 30 or the middle frame 20; or, the inlet / outlet 311 may also be formed between the middle frame 20 and the base 10, and the door 312 may be movably connected to the top cover 30 or the middle frame 20; or, the inlet / outlet 311 may also be formed between the base 10, the middle frame 20, and the top cover 30, and the door 312 may be movably connected to the middle frame 20, the top cover 30, or the base 10.

[0061] Please see Figure 10 After the top cover 30, middle frame 20, and base 10 are disassembled, the base 10 can be placed into the middle frame 20, and the middle frame 20 can be placed into the top cover 30, thus achieving stacking of the three. The stacking method is not limited to this example; other stacking methods can refer to the stacking method of embodiment 4. In addition, in order to avoid the fastener 29 from hindering stacking, the fastener 29 can also be detachably connected to the middle frame 20. In this embodiment, the fastener 29 is provided with a pivot part, and the middle frame 20 is provided with a locking hole. The fastener engages with the pivot part, and the fastener 29 can also rotate through the pivot part and the locking hole, so that the fastener 29 can easily engage with the top cover 30.
