Description

Technical Field

[0001] The utility model relates to the technical field of pet feeding, and more specifically to an upper cover for a cat litter box and the cat litter box. Background Art

[0002] As people's living standards improve, more and more families keep pets such as cats and dogs. The pet industry has also grown and developed. Whether from the spiritual level of a happy mood or as a lifestyle of leisure and entertainment, owners are willing to spend more time with their pets. Cats are born to use cat litter to bury urine and feces. Families who keep cats at home will buy cat litter boxes, but traditional open cat litter boxes often cause splashing when cats dig litter, making it difficult to clean. Closed cat litter boxes with upper covers are gradually gaining attention.

[0003] There are a lot of public disclosures about the design of closed cat litter boxes, such as the cat litter box provided by the patent with publication number CN207767194U, which hinges one side of the cat litter box to the upper cover and provides snap connections on the other sides, so that the basin body can be kept closed, and the upper cover can be flipped open when the cat litter needs to be cleaned. The cat litter box provided by the patent with publication number CN212212283U has a detachable connection between the upper cover and the bottom shell through snap locking, and a mounting groove for placing a cat litter shovel is provided on the top of the upper cover. Although the above designs can open the upper cover to clean the cat litter, the operation is more cumbersome, and it is necessary to open multiple snaps or move the upper cover with both hands, which does not provide a good user experience. The patent with publication number CN205337151U provides a flip-up fully enclosed cat litter box, in which the cover edge of the upper cover body and the top edge of the bottom shell are connected to each other by a plurality of snaps, and a window is provided on the top wall of the upper cover body, and a transparent cover is hinged on the window. The cat litter can be cleaned by directly opening the transparent cover. Compared with the above design, the convenience is improved, but there is still a situation that the cat litter box and the cover body must be used together at ordinary times, which is not flexible enough in application, and cats are prone to leaking sand and urine from the joint between the cat litter box and the cat litter cover when urinating or scraping litter, which affects hygienic cleaning. It can be seen that there is still a lot of room for optimization in the design of cat litter boxes in practical applications to improve the user experience of cat litter boxes. Utility Model Content

[0004] 1. Technical problems to be solved by the utility model

[0005] In view of the problems in the prior art such as inconvenient operation, poor experience, and insufficient application flexibility in cleaning cat litter in closed cat litter boxes, the utility model intends to provide a cat litter box cover and a cat litter box, which can further reduce the labor intensity of users, improve their operational convenience and flexibility of use, and improve the user experience.

[0006] 2. Technical solution

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0008] The utility model provides a cat litter box, comprising a basin body and an upper cover, the upper cover is detachably connected to the top of the basin body, and the upper end surface of the upper cover is provided with a flap opening for cooperating with the installation of a flap, one side of the flap is rotatably connected to the upper cover, so that the flap can be flipped upward to open the flap opening; the overall height of the basin body and the upper cover after being cooperating with each other is H1, and the vertical extension height H2 of the basin body is not less than the vertical extension height of the upper cover, so that H2 is not less than half of H1. More preferably, the vertical extension height H2 of the basin body is not less than twice the vertical extension height of the upper cover, so that H2 is not less than 2 / 3 of H1.

[0009] This solution specifically provides a large cat litter box design with a high bottom basin. In the traditional closed basin body, the joint position between the basin body and the cover body is relatively low, which is not only easy to leak sand and urine, but also more troublesome and laborious to open or remove the cover body. This solution adopts a high basin body and a low cover body. The basin body itself can provide sufficient sand planing space and sufficient sand planing height. The height of the joint position between the basin body and the upper cover is significantly increased, which can effectively avoid sand and urine leakage at the joint position; and the upper cover and the basin body are detachable. In daily use, you can directly open the flip cover to clean the cat litter inside without removing the entire upper cover. For regular and thorough cleaning, you can completely remove the upper cover. The height of the upper cover is significantly reduced, and the operation is more labor-saving and simple. With this design, the basin body and the upper cover can be completely detached independently. In this design, there is no need to add a connecting structure to the basin body. The basin body can still be used independently as an open basin body, and the flexibility of use is very high.

[0010] Furthermore, in order to improve the convenience of cleaning cat litter, the opening area of ​​the flap of the upper cover in the present design is 50%-100% of the open area of ​​the top of the basin body. In practice, 50%, 70%, 90%, 100%, etc. are adopted, preferably close to 100%; in this way, after the flap is opened, the flap area has enough open space to clearly observe the internal state, and it is convenient to use a cat litter shovel to clean the cat litter without limiting the operation.

[0011] Furthermore, in order to facilitate the placement of the basin and its beautiful shape, the extended lengths of the walls on all sides of the basin are basically the same, so that the top opening of the basin is square. Note that the square basin here means an approximate square. The lengths of the walls on all sides of the basin can be completely consistent or have certain size differences. The overall visual effect is to make the top opening appear to be approximately square, and the shape is exquisite and beautiful. Furthermore, the walls on all sides of the basin are preferably connected by a smooth transition of arc walls, so that the four corners present a rounded design, which is more beautiful and reduces collision damage. At the same time, it is convenient for the processing of the basin and improves its strength. Specifically, the size of the basin can be preferably 50-65cm*50-65cm wide*30-40cm high. For example, in practice, 55cm long*50cm wide*34cm high, 55cm long*55cm wide*34cm high, 65cm long*55cm wide*40cm high, 60cm long*55cm wide*35cm high, etc. can be used. In practice, a rectangular basin structure or other shapes may also be used, which will not be elaborated herein.

[0012] It is further explained that the design further preferably has a length and width of the basin body that are not less than the height of the basin body, and the height of the basin body is not less than 30 cm, which has sufficient planing space and is convenient for the cat to fully move around. An entry and exit opening is provided on the side wall of the basin body, and the entry and exit opening is preferably extended downward from the top of the side wall of the basin body. The large high basin body form and the design of the entry and exit opening have a particularly obvious effect on the structural strength and stability of the basin body. The present scheme further controls the horizontal extension length of the entry and exit opening to be 1 / 3-2 / 3 of the horizontal extension length of the side wall of the basin body. In practice, 1 / 3, 1 / 2, 2 / 3, etc. can be used. On the basis of ensuring flexible entry and exit, the overall structural strength of the basin body, especially the entry and exit opening area, can be guaranteed. Domain structural strength; further preferably, the height of the bottom of the inlet and outlet opening from the bottom of the basin body is 1 / 3-1 / 2 of the height of the basin body; in practice, preferably, the height of the bottom of the inlet and outlet opening from the bottom of the basin body is not less than 10cm, and further preferably it is 12-18cm, such as 12cm, 15cm, 16cm, 18cm, etc., so that the height of the entire basin body and the height of the bottom of the inlet and outlet opening are relatively high, and the volume of the basin body is sufficient, the cat litter is not easy to splash out of the basin body, and it can also be suitable for large cats. By controlling the inlet and outlet opening to maintain a relatively high height, it helps to enhance the structural strength of the overall basin body and prevent the basin body from deformation, thereby adapting to the application requirements of large and high basin bodies.

[0013] As a large basin, the top of the basin is an open space. The larger the basin structure is, the more difficult it is to control the strength and stability requirements for use. This solution further provides edge ribs extending in the direction away from the inner cavity of the basin on the top contour edge of the basin and the contour edge of the inlet and outlet openings. The provision of edge ribs not only helps to improve the overall structural strength of the basin, enhance stability, and avoid obvious shaking when the cat enters and exits, but also facilitates the user to grasp the basin more stably when moving it. And it can be further preferred that the width of the edge ribs at the edge of the contour of the inlet and outlet opening gradually increases downward along the height direction of the inlet and outlet opening. Specifically, the width of the edge ribs at the bottom of the inlet and outlet opening reaches the maximum, and the width of the edge ribs at the bottom of the inlet and outlet opening is 1.5-3 times the width of the edge ribs at the top of the inlet and outlet opening. For example, in practice, 1.5, 1.8, 2.0, 2.5, 2.5, 2.8, 3.0 times, etc. can be selected. In order to facilitate structural processing and maintain strength stability, the width of the edge ribs at the top edge of the inlet and outlet openings extending outward is preferably consistent with the width of the edge ribs around the top of the basin body, and the basin body and the edge ribs are integrally injection molded. The top of the basin body is a large open space, and the area where the inlet and outlet openings are located is more prone to deformation of the basin body. The lower the inlet and outlet openings are, the more likely it is to shake as the cat moves in and out. By setting edge ribs, the width of the inlet and outlet openings can be widened to improve the structural strength. In addition, the width of the edge ribs gradually increases in the height direction, and the width of the area at the bottom that is most prone to trampling and shaking deformation reaches the maximum. This can effectively enhance the structural strength and relative stability of the side walls on both sides of the inlet and outlet openings, alleviate the distortion and deformation between the side walls on both sides of the inlet and outlet openings, and also help improve the comfort of cats stepping on them.

[0014] As one of the specific design forms of the upper cover, the upper cover includes a middle frame and a flip cover, and the upper end surface of the middle frame is provided with a flip cover opening to be installed in cooperation with the flip cover; the bottom of the middle frame is provided with a middle frame slot to be connected to the top of the basin body, and the inner and outer side walls of the middle frame slot are respectively the inner wall of the middle frame and the outer wall of the middle frame, and the inner wall of the middle frame and the outer wall of the middle frame are connected to the inner and outer sides of the top surface of the basin body. The middle frame is directly covered on the basin body by using the middle frame slot structure, which is simple to take and put and can effectively limit the position, and there is no need to change the structure of the basin body, and there is no need to equip the basin body with additional connectors or installation positions, etc., and the structural integrity is not destroyed. After removing the upper cover, the basin body can still be used alone as an open cat litter box, and the application is more flexible and convenient.

[0015] Furthermore, the top edge of the basin body is provided with an outer extending edge rib plate, and the top surface of the edge rib plate is a smooth plane flush with the top surface of the basin body, and the edge rib plate is also embedded in the middle frame slot of the upper cover. The edge rib plate can further enhance the structural strength of the basin body, and is conducive to widening the support area with the middle frame, making it more stable.

[0016] Furthermore, buckles for buckling on the edge ribs are symmetrically provided on the opposite side walls of the middle frame. The buckles are pressed to buckle under the edge ribs, further improving the matching stability between the middle frame and the basin body. A hooking groove extending downward can be provided on the top wall of the buckle, and the hooking groove is used to hook the cat litter scoop.

[0017] Furthermore, an inlet and outlet opening extending downward from the top is provided on the side wall of the basin body, and a movable door panel for closing the inlet and outlet opening is provided at a corresponding position at the bottom of the middle frame, and the movable door panel is rotatably mounted with the bottom of the middle frame. The inlet and outlet opening is extended downward from the top of the side wall of the basin body to a certain depth, and the basin body alone can still be used as an open cat litter box, and it helps to reduce cat litter splashing; a movable door panel is correspondingly provided on the middle frame to close the inlet and outlet opening, which does not affect the cat's entry and exit, and when the cover is closed for use, it can form a closed cat litter box, further preventing cat litter splashing and maintaining hygiene.

[0018] The utility model also provides an upper cover for a cat litter box, the upper cover comprises a middle frame and a flip cover, the middle frame is used to cooperate with the cover and is arranged on the top of the bowl body, the upper end surface of the middle frame is provided with a flip cover opening, one side of the flip cover is rotatably connected with the upper cover, so that the flip cover can be flipped upward to open the flip cover opening; the opening effective area of ​​the flip cover opening is 50%-100% of the opening effective area of ​​the bottom of the middle frame. Similarly, when the upper cover is kept in use, opening the flip cover can open the bowl body to a greater extent, so that the cat litter can be cleaned through the flip cover opening.

[0019] Furthermore, a middle frame slot is provided at the bottom of the middle frame for cooperating with the top of the basin body, and the inner and outer side walls of the middle frame slot are respectively the middle frame inner wall and the middle frame outer wall, and the middle frame inner wall and the middle frame outer wall are used to be cooperating with the inner and outer sides of the top surface of the basin body; or / and, the flap and the middle frame are detachably connected, that is, the flap can be removed from the middle frame, and the middle frame can be retained alone to cooperate with the cover on the basin body and can also be used as an open cat litter box, which is more flexible.

[0052] The utility model is further described below in conjunction with embodiments.

[0053] Example

[0054] Combination Figure 1-Figure 18 As shown, the cat litter box of this embodiment includes a basin body 100 and an upper cover 200 located on the top of the basin body 100. Specifically, the upper cover 200 is detachably connected to the basin body 100, and the upper end surface of the upper cover 200 is provided with a flap opening 211 for cooperating with the installation of a flap 220. One side of the flap 220 is rotatably connected to the upper cover 200, so that the flap 220 can be flipped upward to open the flap opening 211; the overall height of the basin body 100 and the upper cover 200 after being installed is H1, and the vertical extension height H2 of the basin body 100 is not less than the vertical extension height of the upper cover 200, so that H2 is not less than half of H1.

[0055] This embodiment adopts a high basin design, so that the height of the activity space of the entire cat litter box is mainly provided by the basin 100 at the bottom, thereby increasing the height of the joint position of the basin 100 and the upper cover 200, effectively avoiding the leakage of sand and urine from the joint position, and being cleaner and more hygienic; and the basin 100 and the upper cover 200 are detachable, and the upper cover 200 can be completely removed. At this time, the basin 100 can still be used alone as an open cat litter box, and the basin height is relatively high, which also effectively reduces the leakage of sand and urine.

[0056] To further improve the convenience of cleaning cat litter, preferably, the effective opening area of ​​the flap 211 of the upper cover 200 is 50%-100% of the effective area of ​​the top opening of the basin body 100. Opening the flap 220 can leak a large area of ​​the top opening of the basin body 100, making it easy to use a cat litter shovel to quickly clean cat litter.

[0057] In order to optimize the design of the basin body 100, in practice, the basin body 100 can be designed in an approximately square shape, that is, the extension lengths of the walls of the basin body are basically the same, so that the top opening of the basin body 100 is approximately square; more preferably, the walls of the basin body 100 are connected by arc-shaped walls with smooth transition. In this way, the basin body 100 is more beautiful and meets the aesthetic needs of users. Of course, a rectangular or other design can also be adopted. More specifically, the dimensions of the basin body 100 in this embodiment are 55 cm long*50 cm wide*34 cm high.

[0058] As one of the specific structural forms of the upper cover 200, preferably, the upper cover 200 includes a middle frame 210 and a flip cover 220, and the upper end surface of the middle frame 210 is provided with a flip cover opening 211 to be installed in cooperation with the flip cover 220, and correspondingly, the opening area of ​​the flip cover opening 211 is 50%-100% of the bottom opening area of ​​the middle frame 210, and the bottom opening of the middle frame 210 is substantially the same as the top opening size of the basin body 100, so that the middle frame 210 is installed in cooperation with the basin body 100. After the basin body 100 is opened, there is enough open space when the flip cover 220 is opened; the bottom of the middle frame 210 is provided with a middle frame slot 214 that cooperates with the top surface of the basin body 100, and the inner and outer side walls of the middle frame slot 214 are respectively the middle frame inner wall 213 and the middle frame outer wall 212, and the middle frame inner wall 213 and the middle frame outer wall 212 are used to be snapped on the inner and outer sides of the top surface of the basin body 100; the top surface of the basin body 100 is embedded in the middle frame slot 214 of the upper cover 200.

[0059] Traditional closed cat litter boxes in the industry are often designed with a bottom basin and a high cover, and the cover is generally an integrated design installed on the basin, requiring both hands to remove the entire cover in order to clean the cat litter. Even if the cover has a skylight design that can be flipped open separately, the cover itself and the basin are still connected by a relatively complex connection structure, making it impossible to completely remove the cover as a whole, or the process of removing the cover is relatively troublesome, which greatly affects the user experience. Especially when the cat litter box needs to be cleaned as a whole after long-term use, the setting of the cover will cause great inconvenience, and the connection structure between the cover and the basin often requires corresponding changes to the basin structure, resulting in increased basin processing costs and poor applicability.

[0060] In this solution, the upper cover 200 is configured as a two-part structure consisting of a middle frame 210 and a flip cover 220. The flip cover 220 can be flipped open separately, and the middle frame slot 214 is provided at the bottom of the middle frame 210 to directly cover the basin body 100, so that the upper cover 200 and the basin body 100 are very easy to match, and the middle frame slot 214 also has a precise limiting function, which can ensure the accuracy of the matching. When cleaning the cat litter, such as Figure 4 As shown, only one hand is needed to lift the flap 220 to expose the top opening of the basin body 100 for internal cleaning, without removing the middle frame 210 as a whole; when the entire basin body 100 is to be cleaned, the entire upper cover 200 can be removed by directly moving the middle frame 210, and it is completely separated from the basin body 100, making it convenient to clean the basin body 100. Moreover, this design does not require any changes to the structure of the traditional basin body 100, and there is no need to set a connector on the basin body 100 to connect with the upper cover 200, which does not affect the normal use of the basin body 100 alone, and has strong application flexibility and convenience. In this embodiment, the size of the flap opening 211 on the upper end face of the frame 210 is basically the same as the size of the top opening of the basin body 100, that is, the size of the flap 220 is basically the same as the size of the top opening of the basin body 100, and the middle frame 210 only serves as a supporting base surrounding the edges of the top of the basin body 100. For reference, Figure 4As shown, after the flip cover 220 is opened, the top of the basin body 100 can be basically completely opened, providing sufficient space for cleaning operations.

[0061] Combination Figure 5 The structure of the basin body 100 in this embodiment is shown. Preferably, an inlet and outlet opening 110 extending from the top downward is provided on the front wall of the basin body 100, wherein the front wall only refers to the wall where the inlet and outlet opening 110 is located, and the surrounding walls of the basin body 100 can all be used as the surface where the inlet and outlet opening 110 is located. This design is the simplest and most commonly used cat litter box design. In order to maintain the original structure of the basin body 100, this embodiment preferably has a movable door panel 250 for closing the inlet and outlet opening 110 at a corresponding position on the bottom of the middle frame 210, and the movable door panel 250 is rotatably matched with the bottom of the middle frame 210, so that the movable door panel 250 can be turned inside out to open the inlet and outlet opening 110, which is more convenient for cats to enter and exit. More preferably, the movable door panel 250 and the middle frame 210 are detachably mounted. Fig.11 , Fig.13 and Fig.18 As shown, one of the designs that can be adopted is: two groups of relatively distributed mounting plates 270 are provided at the bottom of the middle frame 210, and each group of mounting plates 270 is provided with mounting holes 271, and mounting connecting rods 251 that are inserted into the mounting holes 271 are provided on both sides of the top of the movable door plate 250, and a rotatable flip connection is achieved through the matching of the mounting connecting rods 251 and the hole axis of the mounting holes 271. In order to facilitate the disassembly and installation of the two, along the insertion and installation direction of the mounting connecting rods 251, the mounting plate 270 is provided with an inclined extending auxiliary guide wall 272 at the front side of the mounting hole 271, and the auxiliary guide wall 272 extends inward from the edge of the mounting plate 270 to the position of the mounting hole 271, so that the mounting connecting rod 251 can be inserted into the mounting hole 271 after being guided by the auxiliary guide wall 272. Similarly, one side of the end of the mounting connecting rod 251 is also provided with an inclined extending guide cut surface 252, which makes it easier to gradually enter along the auxiliary inclined wall 272 during insertion or to be more easily disengaged during removal.

[0062] In order to improve the structural stability of the basin body 100, in practice, it is preferred that the top edge of the basin body 100 is provided with an outer extending edge rib plate 120, and the edge rib plate 120 can be designed in a plane shape or a C-shaped or L-shaped cross section, etc., which not only makes the shape more beautiful, but also helps to enhance the structural strength of the basin body 100. In this embodiment, the top surface of the edge rib plate 120 is a smooth plane flush with the top surface of the basin body 100, and the edge rib plate 120 is also embedded in the middle frame slot 214 of the upper cover 200. The edge rib plate 120 effectively widens the top surface of the basin body 100, and has a more stable support plane when installed in conjunction with the middle frame slot 214, and is more stable to use.

[0063] In order to improve the matching stability between the upper cover 200 and the basin body 100 in this embodiment, the design can be further optimized as follows: Fig.14 As shown, a plurality of groups of support ribs 215 are provided circumferentially in the middle frame slot 214, the support ribs 215 are connected between the middle frame inner wall 213 and the middle frame outer wall 212, and the bottom of the support ribs 215 has a support plane for contacting and cooperating with the top surface of the basin body 100. The support ribs 215 can not only serve as reinforcing ribs to effectively enhance the structural strength of the middle frame 210, but also provide multiple support positions around the circumference in the middle frame slot 214 to meet the support strength requirements.

[0064] Similarly, in order to achieve stable support and cooperation between the middle frame 210 and the flip cover 220, the top surface of the middle frame 210 is a smooth plane with an aesthetic shape, and the bottom of the flip cover 220 has a flip cover slot 223 that is engaged with the top surface of the middle frame 210. Fig. 9 As shown, the inner and outer side walls of the flip cover slot 223 are the flip cover inner side wall 222 and the flip cover outer side wall 221, respectively. The flip cover inner side wall 222 is clamped on the inner side of the top surface of the middle frame 210, and the bottom of the flip cover outer side wall 221 is kept flush with the outer edge of the top surface of the middle frame 210. The flip cover inner side wall 222 is used to achieve the matching installation limit, and the flip cover outer side wall 221 is overlapped on the top surface of the middle frame 210 and keeps the edges flush, so that the edges of the flip cover 220 remain flush and smooth after closing, and the shape is beautiful. Similarly, preferably, a plurality of groups of support plates 224 are arranged around the inner edge of the flip cover slot 223 in the circumferential direction, and the support plates 224 are connected between the flip cover inner side wall 222 and the flip cover outer side wall 221, and the bottom of the support plates 224 has a support plane that contacts and cooperates with the top surface of the middle frame 210. The support plate 224 can not only effectively enhance the structural strength of the flip cover 220 , but also provide a plurality of circumferentially-oriented snap-in points for cooperating with the top surface of the middle frame 210 to ensure the stability of the cooperation.

[0065] In order to further improve the installation stability of the middle frame 210 and the basin body 100, it can be further preferably designed as follows: the wall surfaces on the opposite sides of the middle frame 210 are symmetrically provided with buckles 230 for buckling on the basin body 100, and the buckles 230 and the middle frame 210 are preferably detachably connected; the specific structural design is as follows: Figure 14-17 , two groups of upper connecting hooks 233 are symmetrically arranged on the inner side of the upper part of the buckle 230, and the two groups of upper connecting hooks 233 are bent and extended upward and have a clamping portion 234 at the end, and the end surfaces of the two groups of clamping portions 234 that are close to or away from each other are respectively provided with a rotating shaft 235; the middle frame 210 is correspondingly provided with a mounting shaft hole 216 that matches the rotating shaft 235; Fig.15As shown, the mounting shaft holes 216 can be selectively arranged on the support ribs 215 in the middle frame slot 214, and at least one group of the mounting shaft holes 216 on both sides can be selectively designed as edge openings to facilitate the disassembly and assembly of the rotating shaft 235. After installation, the buckle 230 can be turned around the rotating shaft 235. In addition, two groups of lower clamping blocks 232 are symmetrically provided on the inner side of the lower part of the fastener 230, and the lower clamping blocks 232 have a clamping slope 236 for clamping under the side wall of the basin body 100; by pressing the fastener 230 inward, the clamping slope 236 on the lower clamping block 232 can be clamped under the top side wall of the basin body 100, specifically, clamped under the edge rib plate 120 at the top of the basin body 100. Especially when the edge rib plate 120 is an L-shaped rib plate, the clamping slope 236 is clamped into the lower side of the edge rib plate 120, and the clamping state with the basin body 100 can be released by flipping the fastener 230 outward, which is very convenient.

[0066] Similarly, preferably, the flip cover 220 and the middle frame 210 may also be detachably connected. Figure 8 , Fig.10 , Fig.11 and Fig.12 As shown, two groups of flip cover hooks 260 are symmetrically arranged on one side where the flip cover 220 is connected to the middle frame 210, each group of flip cover hooks 260 has an end portion that is bent and extended upward, and a hooking groove 262 is formed between the bent portions; the end portion of the bent portion is a hooking portion 261 for hooking on the inner side of the middle frame 210, and the end surfaces of the two groups of hooking portions 261 that are close to or away from each other are respectively provided with connecting shafts 263, and a matching cavity 280 for accommodating the flip cover hooks 260 is opened in the middle frame 210, and a connecting hole 281 that matches the connecting shaft 263 is correspondingly arranged on the inner wall of the matching cavity 280. By using the matching of the connecting shaft 263 and the connecting hole 281, the flip cover 220 can be flipped open and closed around the connecting shaft 263. Similarly, to facilitate assembly and disassembly, along the insertion direction of the connecting shaft 263, a guide inclined wall 282 extending from the edge to the connecting hole 281 is provided on the inner wall of the matching cavity 280, so that the connecting shaft 263 can be guided by the guide inclined wall 282 to gradually enter the connecting hole 281. Correspondingly, a guide inclined surface 264 extending obliquely is also provided on one side of the end of the connecting shaft 263, so as to facilitate the insertion and disengagement of the connecting shaft 263 and the connecting hole 281. In practice, multiple sets of reinforcing ribs can be provided on the flip cover hook 260 to enhance the structural strength, and as shown in FIG. Fig.12 As shown, a limiting rib 283 can be further provided on the inner wall of the mating cavity 280 above the guiding inclined wall 282. The limiting rib 283 extends longitudinally in the height direction and is used to limit the upward flipping degree of the flip cover hook 260 when the flip cover hook 260 flips upward, so that the flip cover 220 maintains an appropriate and stable opening range.

[0067] In order to improve the convenience of practical application, in this embodiment, a hooking groove 231 extending downward is preferably provided on the top wall of the fastener 230; the hooking groove 231 can extend to the length of the fastener 230 or only extend to the top of the length area. In practice, a cat litter scoop is used to clean cat litter, and the cat litter scoop can be hooked on the hooking groove 231, which is more convenient to use and saves space.

[0068] To improve the flexibility of opening the flip cover 220, a handle 240 may be provided on the top of the flip cover 220, and the flip cover 220 can be opened by pulling the handle 240 with one hand. In addition, the edges around the flip cover 220 preferably adopt an arc-shaped cover plate protruding outward, so as to increase the height space of the basin body 100.

[0069] The cat litter box of this embodiment has a detachable and cooperative installation between the basin body 100 and the upper cover 200, and the installation method is very convenient. There is no need to set a connecting piece on the basin body 100 structure, which does not affect the independent use of the basin body 100. The upper cover 200 is detachably connected to a flip cover 220 that can be flipped open, which can realize one-handed opening and cleaning, and the convenience is significantly improved. The various components are detachably connected to facilitate transportation and assembly. Users can also flexibly adjust according to their needs. The large high basin body design effectively reduces the leakage of sand and urine at the seams of the upper cover, which is cleaner and more hygienic.
