[0028] Currently, automatic litter boxes with rollers generally consist of a base and a rotating roller. The rotation of the roller separates cat feces and litter, thus keeping the litter box clean, while the cat feces are discharged into a collection box outside the roller. However, when the roller is rotating to clean up feces, there is a possibility that a cat may enter the litter box. When the roller rotates, it may become misaligned with the collection box. If the cat extends out of the roller during this process, it may get stuck between the roller and the collection box, leading to a safety accident.
[0029] In view of this, and in response to the problem that existing cat litter boxes may cause cats to get stuck between the roller and the collection box, leading to safety accidents, this utility model proposes a cat litter box 100 to improve the above-mentioned problems.
[0030] The specific structure of the cat litter box 100 of this utility model will be described below:
[0031] Please refer to Figures 1 to 5 This utility model proposes a cat litter box 100, which includes: a base 10, the base 10 having an installation cavity 11; a waste collection box 20, the waste collection box 20 being disposed on the outside of the base 10, the waste collection box 20 including a box body 21 and a cover 22, the box body 21 being connected to the base 10, the cover 22 being rotatably connected to the box body 21, and a collection port 201 being formed between the cover 22 and the box body 21; and a roller 30, the roller 30 being rotatably disposed in the installation cavity 11, the roller 30 having a receiving cavity 31 having an opening 311, and the roller 30 also having an outlet 34; wherein, the cat litter box 100 has a defecation state and a screening state in which the roller 30 rotates relative to the base 10; in the defecation state, the outlet 34 is connected to the collection port 201.
[0032] Specifically, the litter box 100 includes a base 10, a waste collection box 20, and a roller 30. The base 10 is used to install the roller 30 and provide the roller 30 with rotation space. The roller 30 is used to hold cat litter for the cat to use the toilet. The waste collection box 20 is used to collect the cat's feces.
[0033] The roller 30 is rotatably connected to the mounting cavity 11 of the base 10. The roller 30 can be rotatably connected by a motor or by a gear and rack. The cover 22 is rotatably connected to the box 21, either by a rotating shaft or by a gear and rack.
[0034] In the screening state, the rotating roller 30 gradually separates the cat litter and feces within the receiving cavity 31. After the fecal clump 200 is screened out, it is discharged from the collection port 201 into the fecal collection box 20 through the outlet 34. Figure 3 When the roller 30 rotates, if the cat gets stuck between the roller 30 and the cover 22, the cover 22 will rotate with the cat under the force, and the size of the collection port 201 will change.
[0035] In one embodiment, the cat litter and feces in the receiving cavity 31 can be separated by rotating the roller 30, causing the cat litter and fecal clumps 200 in the receiving cavity 31 to flow toward the screen, thereby separating the fecal clumps 200. The roller 30 continues to rotate, and the feces enter the collection box 20 from the collection port 201.
[0036] During defecation, after the roller 30 filters out the fecal clump 200, the roller 30 continues to rotate, so that the outlet 34 is connected to the collection port 201, and the fecal clump 200 falls out from the outlet 34 of the roller 30, thus discharging the fecal clump 200 into the fecal collection box 20.
[0037] like Figure 3 and Figure 4 The outlet 34 between the waste collection box 20 and the roller 30 and the collection port 201 form a waste passage. Since the cover 22 is rotatably connected to the box 21, the cover 22 can be flipped. Therefore, when the cat extends out of the roller 30 and its body or paw is stuck between the roller 30 and the cover 22, the cover 22 can be flipped along with it, thus giving the cat room to move and allowing the cat to easily pull out its stuck paw, so as to avoid the cat being fixed and trapped.
[0038] In other words, when a cat extends from the opening 311 of the roller 30 and touches the litter box 20, if it gets stuck, the rotatable cover 22 will rotate upon sensing pressure. The cover 22 can flexibly adjust its position according to the cat's movements, providing a cushioning mechanism to release pressure on the cat and prevent injury. Furthermore, the cat may feel frightened or stressed due to being stuck, leading to a more violent reaction. The rotatable cover 22 reduces the occurrence of this, allowing the cat to escape without causing further harm and reducing the likelihood of a stress response. This design increases the reliability of the litter box 100 and improves the user experience.
[0039] The rotatable cover 22 makes it easier to open and clean the waste collection box 20, which is convenient for the owner to clean the waste collection box 20 regularly, simplifies the daily maintenance process, and is also easy to clean, maintaining good hygiene conditions.
[0040] This utility model's technical solution involves rotating a roller 30 within the mounting cavity 11, with the base 10 providing rotational space for the roller 30. The roller 30 rotates relative to the base 10, allowing the litter box 100 to have both a screening and a defecation state. In the screening state, the rotation of the roller 30 gradually separates the litter and feces within the containing cavity 31. In the defecation state, the roller 30 continues to rotate, connecting the outlet 34 with the collection port 201, allowing fecal clumps 200 to fall out from the outlet 34 of the roller 30 and be discharged into the collection box 20. The collection box 20 is located on the outside of the base 10 to facilitate the collection of the screened fecal clumps 200. By making the cover 22 rotatable, when a cat extends from the opening 311 of the roller 30 between the roller 30 and the cover 22 and gets stuck, the cover 22 can rotate relative to the box 21 under force, allowing the cat to easily remove its stuck paws or body, preventing accidents.
[0041] In an embodiment of this utility model, the cover 22 includes a body 221 and a flip cover 222. The body 221 is detachably connected to the box body 21, and the flip cover 222 is rotatably connected to the body 221. The flip cover 222 is spaced apart from the box body 21 and forms the collection port 201.
[0042] In detail, the detachable connection between the main body 221 and the box 21 makes the waste collection box 20 easier to clean. The detachable connection can be a snap-fit connection or a threaded connection, etc. Figure 3 The front end of the cover 22 is designed to be rotatable, while the main body 221 remains fixed, reducing unnecessary shaking. The design of the flip cover 222 allows it to rotate under pressure, thus protecting the cat from injury. When the cat accidentally puts its paw or other body part into the collection port 201 and feels obstructed, the flip cover 222 can respond quickly and rotate, providing immediate room for movement and preventing the cat from being trapped.
[0043] In an embodiment of this utility model, the cover 22 further includes a rotating shaft (not shown) and a torsion spring (not shown). The rotating shaft is fixedly connected to the body 221, the flip cover 222 is rotatably connected to the rotating shaft, the torsion spring is sleeved outside the rotating shaft, and one end of the torsion spring is connected to the flip cover 222.
[0044] Specifically, by setting a rotating shaft and a torsion spring to connect the flip cover 222, the rotating shaft allows the flip cover 222 to rotate freely when subjected to external force, while the torsion spring makes the rotation of the flip cover 222 smoother and more stable, ensuring that the flip cover 222 can rotate flexibly and avoid pinching the cat. At the same time, the torsion spring provides a restoring force, allowing the flip cover 222 to naturally return to its initial position when there is no external force, ensuring the size of the collection port 201, which facilitates the discharge of feces 200 into the feces collection box 20 during defecation, maintaining the consistency of the device's working state and reducing the need for manual adjustment by the user.
[0045] In an embodiment of this utility model, the flip cover 222 rotates relative to the body 221 and has an initial position. The flip cover 222 rotates up and down along the height direction of the base 10 relative to the initial position, and the rotation angle of the flip cover 222 relative to the initial position is 30 degrees.
[0046] It is worth noting that, such as Figure 3 The flip cover 222 is initially positioned in the center. It can rotate up and down relative to this initial position, with a rotation angle of 30 degrees. This means the flip cover 222 has a rotation range of 60 degrees, providing ample space for the cat and reducing the risk of injury. Furthermore, even if the flip cover 222 is not over-opened or over-closed, the spring provides effective restoring force within a certain range, allowing it to quickly and accurately return to its initial position after each operation. This ensures a stable return to the initial position and reduces defecation problems caused by improper flip cover positioning.
[0047] Meanwhile, the 60-degree rotation angle of the flip cover 222 results in a smaller range of motion for the flip cover 222, maintaining the neat and compact appearance of the device.
[0048] In an embodiment of this utility model, the box body 21 is detachably connected to the base 10 by a snap fastener, and the waste collection box 20 has an installed state and a stored state; in the installed state, the box body 21 is connected to the base 10; in the stored state, the box body 21 and the cover 22 are stored in the receiving cavity 31 of the roller 30.
[0049] Specifically, such as Figure 4When the box 21 is installed on the base 10, it can collect stool pellets 200. The box 21 can be detached from the base 10, and the cover 22 can also be detached from the box 21. The box 21 and cover 22 can be stored in the receiving cavity 31 of the roller 30, significantly reducing the product's volume, facilitating packaging, transportation, and storage, reducing the required packaging space and materials, and lowering logistics costs. For users, this makes it convenient to store the product at home. During transportation, storing the stool collection box 20 inside the roller 30 also protects it from external impacts and compression, reducing potential physical damage during transport.
[0050] Meanwhile, the box 21 is connected to the base 10 via a snap-fit (not shown in the figure). The snap-fit connection is simple and intuitive, and disassembly and assembly can be completed without tools. Users can easily disassemble and reinstall the waste collection box 20 for easy cleaning and replacement of parts. The snap-fit can be a push-button snap-fit, a spring snap-fit, or a hook snap-fit, etc.
[0051] By designing the box 21 to be detachably connected to the base 10 via a snap-fit and to be able to switch between the installed and stored states, this design not only improves the convenience of transporting and storing the litter box 100, but also enhances the user experience and optimizes the performance of the device.
[0052] In an embodiment of this utility model, the outer wall of the cover 22 is provided with an arc-shaped surface.
[0053] It is worth noting that, such as Figure 1 The outer wall of the lid 22 is designed with an arc shape. The arc surface can better adapt to the circular contour inside the roller 30, making full use of the limited space. This allows the lid 22 to fit more tightly into the internal space of the roller 30, reducing the overall volume occupied. When stored, the entire waste collection box 20 can be placed more compactly within the receiving cavity 31 of the roller 30. Furthermore, the rounded edges of the lid 22 will not easily scratch or injure pets or people like sharp right angles. The arc-shaped corners reduce the risk of accidental injury to cats and other family members.
[0054] In an embodiment of this utility model, a collection groove 12 is provided at the bottom of the base 10, and a protective net 13 is provided at the opening 311 of the collection groove 12.
[0055] In detail, such as Figure 3 and Figure 5The base 10 has a collection trough 12 at its bottom to collect fine kitten litter particles that were not completely separated during the sieving process, ensuring they do not scatter on the ground and keeping the environment clean. When the roller 30 rotates, if a cat puts its head into the collection trough 12, it will be trapped between the roller 30 and the collection trough 12. Therefore, by setting up a protective net 13, the cat's body and paws are prevented from sinking into the collection trough 12, thus preventing the cat from being trapped when the roller 30 rotates while the cat is at the bottom of the base 10.
[0056] In an embodiment of this utility model, the base 10 and the protective net 13 are integrally formed.
[0057] Specifically, the base 10 and the protective net 13 are integrally molded, making them a sturdy whole, enhancing structural stability, and improving the overall strength and durability of the base 10. This also simplifies the manufacturing process, reduces assembly steps, and allows for a seamless connection between the protective net 13 and the base 10. Users don't need to worry about the protective net 13 falling off or shifting, providing a more intuitive and reliable user experience.
[0058] In an embodiment of this utility model, the roller 30 is provided with a cat litter storage bin 32 and a feces storage bin 33 that are connected to the accommodating cavity 31. The feces storage bin 33 is provided with an outlet 34. In the screening state, the outlet 34 is closed, and the cat litter and feces located in the accommodating cavity 31 are discharged into the cat litter storage bin 32 and the feces storage bin 33 in sequence.
[0059] In detail, such as Figure 2 and Figure 4 The roller 30 contains a litter storage bin 32 and a feces storage bin 33. As the roller 30 rotates clockwise, it separates the litter and feces sequentially, allowing them to enter the litter storage bin 32 and the feces storage bin 33 under gravity. Then, the roller 30 rotates counter-clockwise... Figure 4 The outlet 34 opens and connects to the collection port 201, allowing the fecal clumps 200 collected in the fecal clump storage chamber 33 to flow into the fecal collection box 20 under gravity. The device automatically sorts cat litter and feces without user intervention.
[0060] The opening and closing of outlet 34 can be controlled by an electric push rod structure, a solenoid valve structure, or a sliding door can be installed and controlled by an electromagnet attracting the sliding door.
[0061] In an embodiment of this utility model, the cross-section of the roller 30 is semi-circular, the roller 30 has an arc surface 35 and a plane 36, the opening 311 is provided on the plane 36 of the roller 30, and the outlet 34 is provided on the arc surface 35 of the roller 30.
[0062] It is worth noting that, such as Figure 2 One side of the roller 30 is completely open, forming a large entrance that allows cats to enter and exit freely, reducing any sense of obstruction. The larger opening 311 also makes it easier for users to access the interior of the roller 30 for thorough cleaning and inspection, improving cleaning efficiency.
[0063] The curved surface 35 is designed with an outlet 34, which ensures that the separated feces can fall directly into the fecal clump storage chamber 33 under the action of gravity, reducing the possibility of scattering.
[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
