Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, and in particular relates to a semi-enclosed cat litter box. Background Technology

[0002] Cats are one of the most commonly kept pets by humans. They have a habit of burying their excrement in a sandy substance. For this reason, litter boxes are designed as toilets for cats. Most existing litter boxes are either fully open or semi-enclosed. Semi-enclosed litter boxes usually require the owner to manually reach into the litter box through the cat's entrance to remove the excrement. Sharing an entrance with the cat can lead to hygiene problems for the owner.

[0003] Chinese patent application No. 201922327198.5 discloses a cat litter box, including a detachably connected base and a top cover. The box body formed by the base and the top cover is saucer-shaped. The top cover is divided into a fixed cover and a movable cover in the front-to-back direction. The fixed cover is detachably fixed to the base and has a doorway for the cat to enter and exit. The movable cover has a pin at its bottom where it connects with the fixed cover. The movable cover can rotate around the pin to enter the inside of the fixed cover to open the movable cover.

[0004] In the above technical solution, a doorway for the cat to enter and exit is set on the fixed cover, and a movable cover connected to the fixed cover by a pin is set on the back of the fixed cover, allowing the owner to open the litter box for cleaning. However, in the above technical solution, the doorway used by the cat and the space for the owner to reach in after opening the movable cover are located on the front and back sides of the litter box. In actual use and placement, the litter box is usually close to the wall or corner, and the doorway used by the cat usually faces the side away from the wall. This means that when the owner manually reaches into the litter box through the movable cover to clean the litter, the litter box needs to be moved. The litter box filled with litter is relatively heavy, making it difficult to move and inconvenient to use. In addition, in the above technical solution, the litter box cover needs to be removed before the litter can be replaced, making it cumbersome and inconvenient for the owner to change the litter regularly. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a semi-enclosed cat litter box is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A semi-enclosed cat litter box includes a base and a top cover detachably connected to the base. The area enclosed by the top cover and the base is a defecation space. A bottom basin for holding cat litter is slidably connected inside the base. The bottom basin is detachably connected to the base. The top cover has a window with an opening in the same direction of sliding as the bottom basin. A door and a sliding assembly for sliding the door are slidably connected inside the window. An opening for a pet cat to enter the defecation space is provided on the side of the top cover relative to the direction of sliding of the bottom basin.

[0008] Install the litter box inside the base and fasten the top cover onto the base, creating a closed space for the cat to relieve itself. Adjust the overall angle of the litter box so that the back of the litter box is against the wall and the opening faces the owner. When the cat needs to relieve itself, it will crawl through the opening into the closed space to do so. When the owner needs to clean the litter, manually open the door to connect the space to the outside, then use a litter scoop to clean it. When the owner needs to change the litter, pull the litter box out of the base and remove it, then replace the litter inside.

[0009] The base and the bottom can slide relative to each other using any sliding structure in the prior art that enables relative sliding between the two parts, such as a slide rail, a convex strip and a slide groove.

[0010] The sliding component can be a moving structure that restricts the door from sliding in the vertical or horizontal direction, such as a vertically or horizontally set pin or a vertically or horizontally set slide rail.

[0011] This invention provides an opening for the cat to enter through the window on the side of the lid without affecting the overall structural strength of the litter box. This allows the device to be placed close to a wall or corner without obstructing the owner's hands or the cat's access to the excretion space. When the owner needs to clean the litter, they can do so through the window without moving the litter box. When the owner needs to change the litter, they can do so without disassembling the entire lid.

[0012] Preferably, the overall shape of the combination of the top cover and the base is a fortress-like structure with a tapered circumference along its own axis. The shape of the door body matches the side end face of the top cover, and the sliding component allows the door body to slide away from the opening along the top cover.

[0013] By designing the overall shape of the lid and base as a fortress, the litter box can be made more stable during use, preventing it from being bumped during play or tipped over during use, thus preventing litter and excrement from spilling out.

[0014] Preferably, the top cover and the base each have a first extension and a second extension extending laterally. The first extension and the second extension are right-angled structures that extend outward along the entire litter box. One right-angled end face of the right-angled structure is located on the back side of the window, and the other right-angled end face of the right-angled structure is located on the side side of the window. The opening is formed on the right-angled end face of the side side of the right-angled structure.

[0015] By incorporating a first extension and a second extension, the litter box extends outward in a right-angled structure. The second extension makes the base appear as a slanted teardrop shape when viewed from above. This provides a larger support surface when the litter box is placed against a wall, compared to a saucer-shaped or cylindrical structure. This results in better stability for the litter box and prevents it from shifting or rotating due to accidental contact.

[0016] Preferably, the sliding assembly includes an upper sliding groove fixedly disposed within the upper cover and a protrusion extending upward from the upper end of the door body. The upper sliding groove is fixed to the same curvature as the upper cover, and the protrusion is embedded in the upper sliding groove and can slide along the curvature of the upper sliding groove.

[0017] By setting a raised strip and a sliding groove structure on the top of the door, the door can slide relative to the top cover, thus preventing splashed cat litter particles from getting embedded in the groove and affecting its use.

[0018] Preferably, the door body has symmetrical raised strips with the same curvature at both the upper and lower ends, and the base has a sliding groove for the raised strips to be inserted.

[0019] By setting convex strips and sliding grooves on both the top and bottom sides of the door, the door can slide relative to the top cover, thus ensuring the stability of the door during the sliding process. When the door is made of elastic materials such as plastic parts, it can prevent the door from deforming and becoming difficult to slide during use.

[0020] Preferably, the upper end of the door body is provided with a lip extending into the excretion space, and a protrusion located at the upper end of the door body is fixedly disposed on the lip.

[0021] By setting a lip at the top of the door, the overall door body is made to match the inclined curvature of the cover, thereby preventing the door from jamming during use and ensuring the structural strength of the door body.

[0022] Preferably, the protrusion at the upper end of the door body includes a first contraction section with a width smaller than the width of the upper sliding groove, and the protrusion at the lower end of the door body includes a second contraction section with a width smaller than the width of the lower sliding groove.

[0023] Because the convex strip has a narrow contraction section, it provides space for the convex strip to bend and deform when the door inevitably deforms during sliding, thus preventing the door from getting stuck during sliding.

[0024] Preferably, a door handle is provided on the outer surface of the door near the edge of the window in the sliding direction of the door, so as to facilitate the keeper to push the door.

[0025] Preferably, a support member is provided between the two side walls of the lower end of the base relative to the sliding direction of the basin, a deodorizing block is provided on the upper cover, and a perforated plate is provided at the opening of the base opposite the position of the basin.

[0026] The base and bottom shell are supported by a support structure to prevent deformation caused by the cat's own weight when using the litter box, which would make it difficult to remove the litter box from the base. The deodorizing block is used to mask the odor after the cat's excrement, improving the owner's comfort. The perforated plate makes it easy for the cat to remove the litter granules embedded in its paws after excrement.

[0027] Preferably, the second extension can also be used with a walk-in step, which makes it easier for the pet cat to step over the second extension and enter the hole.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] While ensuring the structural strength of the base and top cover, the opening for the pet cat to enter is set on the side relative to the sliding direction of the base, so that when the device is placed close to a wall or corner, the opening and window are not obstructed by the wall, thus eliminating the need for the owner to move the base when cleaning or changing the cat litter, making it easy to use.

[0041] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] like Figure 1 As shown, this embodiment discloses a semi-enclosed cat litter box, including a base 11. The upper surface of the base 11 has recessed steps 112 along its four perimeter that match the wall thickness of the upper cover 12. The upper cover 12 is detachably connected to the base 11 via these recessed steps 112. The overall shape of the upper cover 12 and the base 11 after assembly is a fortress-like structure with a tapered circumference along its own axis. Figure 2 As shown, the base 11 has an enclosed structure with a horizontal opening for the base 13 to slide horizontally. The horizontal opening has flat walls at both ends along the width of the base 13. The base 13 can be detached from the base 11 by sliding between the flat walls. A handle 131 is provided on the front side of the base 13 for easy gripping by the owner. The area formed between the top cover 12 and the base 13 is a closed space for the cat to defecate. A perforated plate 26 is provided at the opening of the base 11 opposite the position of the base 13.

[0044] like Figure 1 As shown, the upper cover 12 has a window 14 with an opening in the same sliding direction as the base 13. A door 15 and a sliding assembly for sliding the door 15 are slidably connected inside the window 14. A door handle 153 is provided on the outer surface of the door 15 near the edge of the window 14 in the sliding direction of the door 15. The upper cover 12 and the base 11 have a first extension 111 and a second extension 121 extending laterally, respectively. The first extension 111 and the second extension 121 are right-angled structures extending outward along the entire litter box. The second extension 121 makes the base 11 appear as an oblique teardrop shape when viewed from above. One right-angled end face of the right-angled structure is located on the back side of the window 14, and the other right-angled end face of the right-angled structure is located on the side side of the window 14. The opening 1211 is opened on the right-angled end face of the side of the first extension 111.

[0045] When a cat needs to use the litter box, it can crawl through the hole 1211 into the enclosed space to relieve itself. When the owner needs to clean the litter box, they can manually open the door 15 to connect the litter box with the outside, and then use a litter scoop to clean it. When the owner needs to change the litter, they can pull the litter tray 13 out of the base 11 and remove it, and then replace the litter in the litter tray 13.

[0046] like Figure 1 As shown, a fastening element 25 is provided between the outer perimeter of the opening 1211 and the right-angled end face of the side of the second extension 121. The fastening element 25 is a U-shaped plate, which is used to strengthen the structural strength between the first extension 111 and the second extension 121, thereby ensuring the stability of the base 11 and the top cover 12 after assembly.

[0047] like Figure 3 , Figure 4 , Figure 5 As shown, the sliding assembly includes an upper sliding groove 17 fixedly installed in the upper cover 12, an upper protruding strip 16 and a lower protruding strip 18 symmetrically arranged at the upper and lower ends of the door body 15 with the same curvature, and a lower sliding groove 19 fixedly installed in the base 11. The upper end of the door body 15 is provided with a lip 151 that matches the curvature of the bunker-shaped structure and extends into the enclosed space. The upper protruding strip 16 is fixedly installed on the lip 151, and the lower protruding strip 18 is fixedly installed on the lower end face of the door body 15. The upper protruding strip 16 includes a contraction section 161 with a width smaller than the width of the upper sliding groove 17, and the lower protruding strip 18 includes a contraction section 161 with a width smaller than the width of the lower sliding groove 19. The lower protruding strip 18 can be a curved structure with a thickness smaller than the lower end face of the door body 15, so that the door body 15 can sit on the base 11, or the lower end face of the door body 15 is provided with a horizontal baffle 152 for thickening, and the lower protruding strip 18 is fixedly installed on the lower end face of the door body 15 through the horizontal baffle 152.

[0048] like Figure 6As shown, a support member 20 is provided between the two side walls of the lower end of the base 11 relative to the sliding direction of the basin 13. The support member 20 is located at the lower end of the basin 13. The support member 20 includes a horizontal rod 201 and columns 202 fixedly installed at both ends of the horizontal rod 201 along its length. The upper surface of the horizontal rod 201 is a groove surface 203 that matches the curvature of the bottom surface of the basin 13, so that the upper surface of the horizontal rod 201 is completely in contact with the bottom end of the base 11, preventing the basin 13 from deforming when used by the pet cat, and ensuring the structural strength of the connection between the horizontal rod 201 and the column 202.

[0049] The upper ends of the two columns 202 are provided with protrusions 204, and the base 11 is provided with mounting holes (not shown in the figure) that cooperate with the protrusions 204, so that the columns 202 and the base 11 can be detachably connected.

[0050] like Figure 7 , Figure 8 As shown, two deodorizing blocks 23 are symmetrically arranged on the upper cover 12. The two deodorizing blocks 23 are composed of symmetrically arranged hollow shells. Each deodorizing block 23 includes a protrusion 233, a connecting part 232 and a box body 231 arranged sequentially from top to bottom. The outer surface of the box body 231 is provided with a buckle 2311. The upper cover 12 is provided with a deodorizing block 23 assembly groove 21. The deodorizing block 23 assembly groove 21 is connected to a deodorizing box assembly groove 22 for placing the box body 231 of the deodorizing block 23. The protrusion 233 is located on the outside of the upper cover 12. The diameter of the connecting part 232 is larger than the diameter of the protrusion 233. The connecting part 232 is tightly fitted into the deodorizing block 23 assembly groove 21, so that the box body 231 is installed in the deodorizing box assembly groove 22 through the buckle 2311.

[0051] The protrusion 233 of the deodorizing block 23 and the fastener 25 can be set according to actual needs, such as the shape of a human head, or the shape of an animal or other cartoon character's head.

[0052] The upper wall of opening 1211 can be fitted with bells, as is currently known. Figure 9 As shown, the second extension 121 located at the lower end of the opening 1211 can be used with a walk-in step 24, wherein the walk-in step 24 includes at least one flat portion 241 for closely abutting the end face of the second extension 121.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that: Figure 10 As shown, the walk-in step 24 used in conjunction with the second extension 121 includes two columnar structures of different heights. The cross-sectional shape of each columnar structure can be set according to actual needs, such as the shape of a human head, or the shape of an animal or other cartoon character's head.
