Description

Technical Field

[0001] This utility model relates to the field of cat litter box technology, and more specifically, to a top-mounted cat litter box cover and the same. Background Technology

[0002] Litter boxes are an indispensable hygiene facility in cat-owning households, and their use is widespread. Most litter boxes on the market are open or semi-enclosed, allowing cats to freely enter and exit through side openings. However, in practice, because cats habitually bury their excrement after urinating, litter particles easily adhere to their paws and around their bodies. When a cat walks out of the litter box, these particles are easily carried out and scattered on the surrounding floor. This not only increases the daily cleaning workload for owners but can also affect the cleanliness and hygiene of the indoor environment.

[0003] Currently, some cat litter boxes in the industry are equipped with pedals or channels with sand leakage holes to reduce cat litter spillage through physical interception, such as top-out litter boxes. These boxes have an outlet at the top and a pedal to allow the cat litter to fall back into the box. However, the actual effect is still not ideal, and the convenience of use is generally not high, making it difficult for users to clean the litter box. The user experience needs further optimization. Utility Model Content

[0004] 1. Technical problem to be solved by the utility model In view of the fact that the convenience of using top-out cat litter boxes in the existing technology still needs to be improved, this utility model intends to provide a top-out cat litter box cover and cat litter box. The top-out cat litter box design can effectively reduce cat litter scattering and has high convenience of use, which can effectively improve the user experience.

[0005] 2. Technical Solution To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model discloses a top-mounted litter box cover, comprising: Side cover, configured to be mounted around the top of the basin, with an open space inside; The footboard is located within an open space enclosed by a side cover, which extends upward beyond the height of the footboard. The footboard has an entrance / exit for the cat to enter and exit, as well as a sand-draining channel for sand to pass through. The side cover plate is provided with a basin mounting part, which is configured to be detachably connected to the basin. One end of the pedal is equipped with a mounting piece, which rotates and engages with the corresponding mounting position on the side cover, allowing the pedal to flip relative to the side cover to open and close the top opening of the basin.

[0006] This invention features a top-loading design for the litter box lid, allowing cats to enter and exit from the top. Stepping on the pedal effectively flushes litter from the cat's paws back into the box, reducing litter spillage. Compared to typical top-loading designs, this invention utilizes a detachable mounting section on the side cover, allowing the litter box lid to be easily removed for individual cleaning. Furthermore, the pedal and side cover are flip-up, enabling easy cleaning without removing the lid; simply flip the pedal to open the box. This design offers high convenience.

[0007] Furthermore, the mounting parts of the foot pedal and the mounting positions on the side cover are detachable, meaning that the foot pedal and the side cover are detachably rotated together. Depending on the user's cleaning needs, the entire litter box cover can be removed for cleaning, or only the foot pedal can be removed for cleaning, effectively improving the flexibility and convenience of cleaning each component.

[0008] Furthermore, along the length of the pedal, side support parts are provided on both sides of the inside of the side cover plate, and the middle area of ​​the pedal is supported on the side support parts, which effectively improves the stability of the pedal support and prevents the pedal from deforming.

[0009] Furthermore, the pedal is equipped with multiple treadle strips, forming sand-draining channels between adjacent treadle strips; the downward extension height of each treadle strip is no less than 0.5cm. This design effectively prevents cats from getting their claws stuck inside the treadle strips during pedaling, making them difficult to pull out and potentially causing injury.

[0010] Furthermore, the treadle has an upward-protruding top for the cat to step on, and the left and right sides of the top protrusion have downward-sloping guides to accelerate the flow of cat litter into the litter channel.

[0011] Furthermore, the treading ribs are hollow ribs, forming downward-opening rib cavities inside; Or / and, there are connecting ribs between adjacent step ribs, and the connecting ribs are connected to the bottom position in the height direction of the step ribs.

[0012] Furthermore, along the height direction, the side cover includes an upper plate and a lower plate, with the upper plate extending upward beyond the height of the pedal and the lower plate extending downward below the pedal, and the height of the upper plate not less than the height of the lower plate.

[0013] Furthermore, the width of the stepping ribs is 10-20mm, and the width of the stepping ribs is at least twice the width of the sand leakage channel.

[0014] This utility model also provides a top-mounted litter box, including a litter box body and a litter box cover as described above, with a side cover plate detachably mounted on the top of the litter box body via a litter box mounting part.

[0015] Furthermore, the bottom of the side cover plate is provided with an installation groove that fits and engages with the top of the basin, and multiple sets of limiting ribs are arranged around the circumference of the installation groove to abut against the wall of the basin.

[0016] 3. Beneficial effects Compared with the prior art, the technical solution provided by this utility model has the following advantages: (1) The cat litter box of this utility model adopts a top-out design. The cat litter can be effectively dropped by the pedal, reducing the cat litter from being carried out. The lid and the body of the litter box are detachable, allowing the lid or the body to be cleaned separately. The pedal and the side cover in the lid are flipped together, allowing the cat litter to be cleaned directly without removing the lid. The convenience and flexibility of the application are significantly improved, and the difficulty of cleaning the body or lid is reduced, further enhancing the user experience.

[0017] (2) The cat litter box of this utility model adopts a deep design for the stepping ribs, with a downward extension height of not less than 0.5cm, which greatly avoids the cat's claws from hooking inward and will not hook onto the bottom wall of the stepping ribs, thus improving the safety of the cat during the stepping process and further improving the structural strength of the stepping ribs, effectively preventing deformation during stepping.

[0018] (3) The cat litter box of this utility model has a central top protrusion on the treading ribs and side guides that extend downward on both sides. The top protrusion can stimulate the cat's paws to expand its toes during the cat's treading process, so that the cat litter that is retracted inside the cat's paws can also be exposed and fall. The side guides that are inclined on both sides can effectively reduce the cat litter from staying on the surface of the treading ribs and promote its rapid and sufficient fall.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example Combination Figures 1 to 11As shown in the figure, this embodiment provides a top-mounted litter box, including a basin body 100 and a litter box cover 200 detachably mounted on the top of the basin body 100. The litter box cover 200 specifically includes a foot pedal 300 and a side cover plate 210. The foot pedal 300 covers the top opening of the basin body 100, and the foot pedal 300 has an entrance / exit 301 for the cat to enter and exit, and a litter leakage channel 314 for litter leakage. The cat can enter and exit the basin body 100 through the entrance / exit 301, and then step on the foot pedal 300, using the litter leakage channel 314 to leak litter during movement. The side cover plate 210 surrounds the foot pedal 300 and extends upward beyond the height of the foot pedal 300. The side cover plate 210 provides support and fixation for the foot pedal 300. The individual side cover plate 210 encloses an open space corresponding to the top opening of the basin body 100, and the foot pedal 300 is correspondingly covered on the open space.

[0026] In this embodiment, the side cover plate 210 is also provided with a basin mounting part 212 for detachable connection with the basin 100. Specifically, it can be assembled by snap-fit, such as in combination with... Figure 1 and Figure 2 As shown, mounting clips are provided on both sides of the side cover plate 210, which engage and fix with corresponding clips on the outer walls of the side panels of the basin 100, ensuring a stable fit between the litter box cover 200 and the basin 100, and making disassembly and assembly relatively convenient. Alternatively, mounting clips can be provided on the outer walls of the side panels of the basin 100, and corresponding clips can be provided on both sides of the side cover plate 210 for engagement and fixation.

[0027] Secondly, in this embodiment, one end of the pedal 300 is also provided with a mounting member 302. The mounting member 302 is rotatably engaged with the corresponding mounting position 211 on the side cover plate 210, so that the pedal 300 can be flipped relative to the side cover plate 210 to open and close the top opening of the basin 100. In specific practice, it can be optionally combined with Figure 4 and Figure 5 As shown, there are outwardly protruding mounting posts on both sides of one end of the pedal 300 along its length direction, and corresponding mounting holes are provided on the side cover plate 210. The mounting posts of the pedal 300 are inserted into the mounting holes to achieve rotational engagement.

[0028] This embodiment adopts a top-out design, with the entrance / exit 301 located on a footrest 300 at the top of the basin. When the cat enters or exits from the top, it will first step on the footrest 300, and during its movement, the cat litter adhering to its paws will be cleaned and fall back into the basin 100, effectively reducing the amount of cat litter carried out. Furthermore, combined with... Figure 1As shown in the diagram, in practice, it is preferable to position the entrance / exit 301 near the rear end of the footrest 300. The front end of the side cover 210 is correspondingly positioned with a lower height, effectively supporting the front end of the footrest 300 from below and forming a passageway for the cat to enter and exit. Positioning this passageway and the entrance / exit 301 at opposite ends of the footrest 300's length effectively extends the cat's walking area, further ensuring sufficient litter fallback. Furthermore, in practice, it is preferable that the left and right width of the passageway at the front end of the side cover 210 is roughly the same as the left and right widths of the footrest 300 and the side cover 210, providing ample space for entry and exit, and making it easier for users to scoop litter without obstruction.

[0029] In this embodiment, the installation part 212 on the side cover plate 210 enables the cat litter box cover 200 to be detachably connected to the basin 100, and the pedal 300 to be flipped to connect with the side cover plate 210. This allows the basin opening and closing to be done by simply flipping the pedal 300, making it easier for users to clean the cat litter directly and providing greater convenience.

[0030] In this embodiment, the litter box cover 200 and the litter box body 100 work together to effectively ensure the activity area and height of the entire litter box, improving the cat's comfort. The side cover 210 forms a raised barrier, effectively increasing the overall height of the litter box. Furthermore, the side cover 210 has an upper plate extending above the height of the footrest 300 and a lower plate located below the height of the footrest 300, wherein the height of the upper plate is not less than the height of the lower plate, forming a high barrier structure around the footrest 300, effectively preventing litter from splashing out and preventing the cat from jumping out from the side, which could cause the litter box cover 200 to become unstable.

[0031] In practice, cat litter boxes are mostly manufactured using injection molding. Large litter boxes are more difficult to process, making them harder to shape and ensuring product strength and quality. This is especially true for deep litter box structures, where mold costs are high and processing is difficult. Furthermore, for large cats, the limited height of top-loading litter boxes means the 300mm footrest is insufficient, causing a feeling of oppression or confinement and affecting the cat's comfort. For users, the need for frequent litter box cleaning is also a concern, as the large size and weight of large litter boxes make cleaning more difficult and intensive, causing considerable inconvenience.

[0032] This embodiment utilizes the cooperation of the side cover plate 210 and the litter box 100, which not only facilitates independent processing of each part, reduces mold processing costs, and improves molding quality and strength, but also effectively increases the overall height after combination, correspondingly raising the height of the footrest 300. This meets the cat's need for activity space, especially reducing the feeling of spatial oppression for the cat when in the litter box position. The side cover plate 210 also forms a raised barrier to effectively prevent the cat from jumping, effectively control litter, and prevent litter from splashing. The flip-open cooperation of the footrest 300 and the side cover plate 210 allows users to directly flip open the footrest 300 to clean the litter box without removing the entire lid during daily cleaning. When it is necessary to clean the litter box 100 or the litter box lid 200 separately, the entire lid can be removed directly, facilitating independent cleaning of each part. In particular, it effectively reduces the difficulty of cleaning the litter box 100, reduces cleaning labor intensity, and makes it easier for users to operate.

[0033] In practice, a further preferred embodiment is that the mounting part 302 of the foot pedal 300 is detachably assembled with the mounting position 211 on the side cover 210, allowing the foot pedal 300 to be removed separately from the side cover 210. This makes it easier for users to clean the foot pedal 300 flexibly. When only the foot pedal 300 needs to be cleaned, only the foot pedal 300 can be removed for cleaning, without having to remove the entire litter box cover 200, thus reducing the difficulty of cleaning. See details for further reference. Figures 2 to 4 As shown, the mounting position 211 on the side cover plate 210 adopts a hole design with a larger upper part and a smaller lower part. The mounting part 302 can be clamped downwards to achieve a tight fixation. When disassembling and assembling, it can be lifted upwards and disassembled from the mounting position 211 for easy disassembly and assembly.

[0034] To ensure stable support for the pedal 300 and prevent deformation from long-term foot pressure, further, side support portions 213 are provided in the middle areas of both sides inside the side cover plate 210 along the length of the pedal 300, in combination with... Figure 3 and Figure 4 As shown, the middle area of ​​the pedal 300 is supported on the side support portions 213 on both sides. Specifically, the bottom inner side of the side cover plate 210 is provided with a flange 215, and the flanges 215 on both sides of the side cover plate 210 extend upward to form side support portions 213. The integrated flange 215 design helps to further improve the structural strength of the side cover plate 210, and the formed side support portions 213 enhance the stable support for the pedal 300.

[0035] Furthermore, the front end of the pedal 300 is provided with a front plate portion 303 that extends outward, and the front end of the side cover plate 210 has a corresponding area with a lower height to form a front channel opening position. The front plate portion 303 is supported on the front channel opening of the side cover plate 210, and as... Figure 4As shown, the front end of the side cover plate 210 is also provided with a front fixing part 214, and the front plate part 303 is provided with a corresponding front buckle 305 that is adapted to the front fixing part 214 for buckling and fixing. This not only effectively supports the pedal 300, but also ensures the installation and fixation of the pedal 300 and the side cover plate 210 bracket, thereby improving overall stability. Through the positioning support at the front and rear ends and the side support part 213 in the middle area, the support strength of the pedal 300 is effectively improved, preventing deformation when stepped on.

[0036] Furthermore, in practice, the stability of the litter box cover 200 and the basin 100 is crucial as cats jump in and out. In this embodiment, in addition to using the basin mounting part 212 to achieve stable assembly of the litter box cover 200 and the basin 100, the bottom of the side cover plate 210 is also provided with a mounting groove 217 that is adapted to and engages with the top of the basin 100, and multiple sets of limiting ribs 218 are arranged circumferentially around the mounting groove 217 to abut against the wall of the basin 100.

[0037] Specifically, in combination Figure 4 As shown, a mounting groove 217 is provided around the bottom of the side cover plate 210. An inner wall rib 216 extends downward from the bottom of the inner wall of the side cover plate 210, and the inner wall rib 216 extends downward beyond the outer wall surface of the side cover plate 210. The mounting groove 217 is located between the inner wall rib 216 and the outer wall surface of the side cover plate 210. Multiple sets of longitudinally extending limiting ribs 218 are provided at intervals on the outer side of the inner wall rib 216. The top of the inner wall of the basin 100 is correspondingly formed with a mounting groove 217 that can be fitted into it. The inner wall of the litter box 100 has a raised edge that corresponds to and abuts against the limiting rib 218. An inclined guide surface can be provided on the limiting rib 218 along its height direction to abut against the raised edge of the inner wall for guidance during installation. When installing the litter box cover 200, the raised edge of the inner wall at the top of the litter box 100 is guided into the mounting groove 217 and pressed against the limiting rib 218, effectively positioning and initially fixing the litter box cover 200 for quick and easy installation. Then, the litter box mounting part 212 is used to fix and assemble it. This prevents shaking during cat jumping or when the user cleans the litter alone.

[0038] It should also be noted that currently common litter box footrests 300 on the market typically use a method of directly drilling holes or slots in the footrest surface for litter leakage. A significant problem is that cat claws can easily get caught in the hole or slot walls and be difficult to pull out, sometimes even resulting in broken claws or injuries, greatly affecting product safety. This embodiment further adjusts the structure of the footrest 300. The footrest 300 is equipped with multiple footrest ribs 310. Specifically, the footrest 300 includes an outer frame 304 around its perimeter, with mounting parts 302 located on both sides of the outer frame 304. Multiple footrest ribs 310 are distributed between the inlet / outlet 301 and the outer frame 304. To improve the litter leakage adaptability to various litter shapes, the multiple footrest ribs 310 extend in a long strip shape, forming long strip-shaped litter leakage channels 314 between adjacent footrest ribs 310. This not only meets the litter leakage requirements of various conventional cat litters on the market, but also effectively leaks litter in the form of long strips, preventing litter from accumulating on the surface of the footrest 300 and failing to fall. Specifically, the downward extension height of the stepping rib 310 is not less than 0.5cm, and can be preferably set to 0.5-1.5cm, such as 0.5cm, 0.8cm, 1cm, 1.2cm, 1.5cm, etc. In practice, the left and right width of the sand leakage channel 314 can be set to 3-6mm, such as 3mm, 4mm, 5mm, 6mm, etc.

[0039] This embodiment employs a heightened treadle rib 310, which significantly increases the thickness of the sand-draining channel 314. In practice, this greatly reduces the risk of cat paws getting caught in the sand-draining channel 314. Even if a cat's paw enters the sand-draining channel 314, it will not hook onto the bottom wall of the treadle rib 310, allowing it to move freely and independently within the channel without obstruction, effectively improving the cat's safety during treading. Furthermore, this design further enhances the structural strength of the treadle rib 310, effectively preventing deformation during treading.

[0040] In practice, a further preferred design is that the treadle rib 310 can be a hollow rib design, forming an inverted U-shaped rib cavity 315 with a downward opening inside. Combined with... Figures 7-9 As shown, this not only makes it easier to process and shape, meeting the high processing requirements of the treadle rib 310, but also effectively saves materials and improves the structural strength and stability of the treadle rib 310.

[0041] Furthermore, to promote sufficient sand settling, combined with Figure 9As shown, the preferred treadle 310 has an upwardly protruding top protrusion 311 for the cat to step on. The top protrusion 311 has downwardly extending side guides 312 on both sides to accelerate the flow of cat litter into the litter channel 314. The top protrusion 311 stimulates the cat's paws to expand their toes during stepping, thus exposing litter trapped inside the paws. The inclined side guides 312 effectively reduce the amount of litter remaining on the surface of the treadle 310, promoting rapid and thorough litter flow. Furthermore, the bottom ends of the side guides 312 on both sides of the treadle 310 are connected to vertically downward side plates 313, forming an arched rib cavity 315 composed of the central top protrusion 311, the side guides 312, and the side plates 313. Specifically, the vertical height from the surface of the top protrusion 311 to the bottom surface of the side plate 313 shall not be less than 0.5cm. In practice, the downward extension height of the side plate 313 may also be not less than 0.5cm.

[0042] Furthermore, in practice, it is preferable that adjacent treadle ribs 310 are connected by connecting ribs 320. The connecting ribs 320 separate the length extension direction of the treadle ribs 310 and also separate the length of the sand-leaking channels 314 between the treadle ribs 310, thereby enhancing the structural strength of the treadle ribs 310 and preventing deformation of the long, strip-shaped treadle ribs 310 under foot pressure. The connecting ribs 320 are located at the bottom of the treadle ribs 310 in the height direction. Thus, the installation of the connecting ribs 320 does not affect the overall height distribution of the treadle ribs 310, nor does it cause damage to the cat claw hooks on the connecting ribs 320.

[0043] Furthermore, in practice, the width of the tread ribs 310 can be preferably set to 10-20mm, such as 10mm, 14mm, 16mm, 20mm, etc., adopting a widened design to improve structural strength and cat's tread comfort, and can also form sufficient sand drop guidance and height depth. The width of the tread ribs 310 should be at least twice the width of the sand leakage channel 314. Specifically, the width gap between adjacent tread ribs 310 can be set to 2-6mm, such as setting the width of the sand leakage channel 314 to 2mm, 4mm, 6mm, etc.

[0044] The top-mounted litter box provided in this embodiment can effectively reduce litter spillage and, through reasonable design, can effectively improve the comfort of cats and the convenience of cleaning for users.

[0045] The above description is illustrative of the present invention and its embodiments. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
