[0062] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0063] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0064] The following reference Figures 1 to 16 Description of a cat litter box according to some embodiments of the present invention.

[0065] like Figures 1 to 9 As shown, an embodiment of this utility model provides a cat litter box, including a base 1, a roller chamber 3, and a collection component.

[0066] Specifically, an arc-shaped groove 15 is provided on the upper surface of the base 1, and a first receiving cavity 2 is provided inside the base 1; a roller chamber 3 is rotatably connected to the arc-shaped groove 15, and a defecation port 4 is provided on the side wall of the roller chamber 3; a collection assembly is slidably connected to the inside of the first receiving cavity 2.

[0067] When the litter box is in use, the collection component inside the first receiving cavity 2 is pulled outwards, so that part of the collection component is located outside the base 1, and the collection component is located at the inlet and outlet of the roller chamber 3. The inlet and outlet are used for the cat to enter and exit the roller chamber 3. When the cat walks out of the roller chamber 3, the cat's paw will carry cat litter, and then the cat will step on the collection component. When the cat's paw comes into contact with the collection component, the cat litter will fall into the collection component, realizing the collection of cat litter, reducing cat litter falling on the ground, and reducing the difficulty of cleaning.

[0068] It should be noted that the roller chamber 3 is detachably mounted on the base 1. When the entire device needs to be disassembled and cleaned, the roller chamber 3 can be removed from the base 1 to facilitate cleaning of the entire device.

[0069] like Figure 6 and Figure 7 As shown, in one embodiment of this utility model, the collecting component includes:

[0070] The sand control disc 5 is slidably connected to the inside of the first receiving cavity 2. The sand control disc 5 has a second receiving cavity 6 inside. The upper surface of the sand control disc 5 has a plurality of sand leakage holes 7 that communicate with the second receiving cavity 6.

[0071] When the litter box is in use, first pull the litter control tray out of the first receiving cavity 2, so that at least half of the litter control tray is outside the first receiving cavity 2. When the cat steps on the litter control tray, the cat litter will fall off the cat's paw. The fallen cat litter will pass through the litter hole 7 and enter the second receiving cavity 6 to collect the cat litter. When the cat litter in the second receiving cavity 6 has been collected to a certain extent, the litter control tray can be completely pulled out of the first receiving cavity 2 to pour out the cat litter. Then, the litter control tray can be put back into the first receiving cavity 2.

[0072] When the entire device needs to be transported or moved, the sand control basin can be completely placed inside the first receiving cavity 2, reducing the difficulty of handling and improving space utilization.

[0073] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, it further includes:

[0074] The third receiving cavity 8 is opened in the base 1. The third receiving cavity 8 is corresponding to the position of the defecation port 4. The upper surface of the base 1 is provided with a defecation port 9 that communicates with the cavity of the third receiving cavity 8.

[0075] The toilet drawer 10 is slidably connected to the third receiving cavity 8.

[0076] After the cat defecates, the roller chamber 3 rotates, causing the feces to be discharged from the defecation outlet 4. The discharged feces fall downwards into the inlet 9, then into the third receiving cavity 8, and finally into the collection drawer 10. During use, a paper pad is placed inside the collection drawer 10, and the feces fall onto the paper pad. After a period of use, the collection drawer 10 is pulled out, the paper pad is removed, a new paper pad is replaced, and the collection drawer 10 is placed back into the third receiving cavity 8. By placing the collection drawer 10 into the third receiving cavity 8, it is easier to move and transport, improving space utilization.

[0077] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, it further includes:

[0078] Motor 11 is fixedly connected to the inlet 9;

[0079] The first baffle 12 is connected to the output end of the motor 11.

[0080] When the drum chamber 3 rotates, the motor 11 drives the first baffle 12 to rotate, so that the inlet 9 is in an open state, allowing the feces to slide smoothly into the collection drawer 10. After the feces enter the collection drawer 10, the motor 11 drives the first baffle 12 to reverse, so that the first baffle 12 blocks the inlet 9 from above, sealing the inlet 9 and preventing the odor of the feces inside the collection drawer 10 from spreading to the outside environment.

[0081] like Figure 1 and Figure 5 As shown, in one embodiment of this utility model, it further includes:

[0082] The mounting cover 13 is located on one side of the roller chamber 3 and above the inlet 9. The lower end of the mounting cover 13 and the upper surface of the base 1 are respectively provided with magnets of opposite magnetic properties. Thus, the mounting cover 13 can be attracted to the upper surface of the base 1 by the two opposite magnets. The mutual cooperation of the opposite magnets can improve the stability of the mounting cover 13 and facilitate the disassembly and installation of the mounting cover 13. A gap of 0-10mm is left between the mounting cover 13 and the roller chamber 3 to avoid friction between the mounting cover 13 and the roller chamber 3 and reduce the difficulty of rotating the roller chamber 3. The mounting cover 13 has a cavity inside, and the side of the mounting cover 13 near the roller chamber 3 and the bottom of the mounting cover 13 are open.

[0083] By setting the mounting cover 13, when the defecation port 4 moves above the defecation inlet 9, the defecation port 4 is located inside the mounting cover 13. When the feces fall, the feces do not come into contact with the external environment. The process of the feces falling is completed inside the mounting cover 13, which further reduces the odor from spreading to the external environment.

[0084] like Figure 8 As shown, in one embodiment of this utility model, it further includes:

[0085] A through hole 14 is formed at the bottom of the arc-shaped groove 15, and the through hole 14 is connected to the first accommodating cavity 2.

[0086] During the use of the device, some cat litter will enter the arc-shaped groove 15. When there is too much cat litter inside the arc-shaped groove 15, the roller chamber 3 is connected to the inside of the arc-shaped groove 15. Therefore, the roller chamber 3 will make noise when it rotates and rubs against the cat litter, and at the same time increase the friction of the roller chamber 3. Therefore, it is necessary to clean the cat litter inside the arc-shaped groove 15 regularly. After removing the roller chamber 3, the cat litter inside the arc-shaped groove 15 is swept away, so that the cat litter passes through the through hole 14 and enters the first receiving cavity 2. The cat litter falls into the second receiving cavity 6 in the litter control basin 5. Compared with the prior art, which requires the use of an external collection device to clean the cat litter here, the present invention is more convenient to collect the cat litter inside the arc-shaped groove 15. It can be directly swept to the through hole 14 and fall into the second receiving cavity 6.

[0087] like Figure 4 and Figure 9 As shown, in one embodiment of this utility model, it further includes:

[0088] The fourth receiving cavity 16 is formed on the outer wall of the mounting cover 13;

[0089] The second baffle 17 is rotatably connected to the outer wall of the mounting cover 13.

[0090] During the use of the device, paper pads or other cleaning tools are required. To ensure the centralized collection of a series of tools, a fourth receiving cavity 16 is provided on the outer wall of the mounting cover 13. Various tools are placed inside the fourth receiving cavity 16. Then, a second baffle 17 is rotatably connected to the outer wall of the mounting cover 13. When it is necessary to take out various tools, the second baffle 17 is rotated to open the second baffle 17 and take out the corresponding tools. Then, the second baffle 17 is rotated again to close the fourth receiving cavity 16.

[0091] An arc-shaped groove 15 is provided on the surface of the base 1. The arc-shaped groove 15 is circular, and the overall shape of the roller chamber 3 is cylindrical. The outer surface of the roller chamber 3 is adapted to the shape of the arc-shaped groove 15. Multiple rollers 21 are rotatably connected to the bottom of the arc-shaped groove 15. When the roller chamber 3 needs to be rotated, it can rotate and drive the rollers 21 to rotate at the same time. The rotation of the rollers 21 can reduce the friction between the roller chamber 3 and the arc-shaped groove 15, thereby reducing the difficulty of rotating the roller chamber 3 and making it easier for the operator to rotate the roller chamber 3. At the same time, the arc-shaped groove 15 can also limit the position of the roller chamber 3 to prevent the position of the roller chamber 3 from shifting.

[0092] like Figures 10 to 15As shown, in one embodiment of this utility model, the filter plate 22 is connected at one end to the inner wall of the fifth accommodating cavity 18; the third baffle 23 is connected at one end to the other end of the filter plate 22, and the other end of the third baffle 23 is connected to one side of the connecting block 20; the filter plate 22, the third baffle 23, the connecting block 20 and the inner wall of the fifth accommodating cavity 18 form a sixth accommodating cavity 30.

[0093] A flow guide surface 24 is located on the side of the connecting block 20 away from the third baffle 23. The distance between the flow guide surface 24 and the third baffle 23 gradually decreases in the direction away from the inlet 19 in the roller chamber 3. A first flow guide plate 25 is fixedly connected to the flow guide surface 24 on the side near the center of the fifth accommodating cavity 18. The shape of the side of the first flow guide plate 25 near the flow guide surface 24 is adapted to the shape of the flow guide surface 24. A second flow guide plate 26 is fixedly connected at one end to the end of the first flow guide plate 25 away from the inlet 19 and at the other end to the defecation port 4. A gap 27 is left between the end of the second flow guide plate 26 near the inlet 19 and the inner wall of the fifth accommodating cavity 18.

[0094] After the cat defecates, both the litter and excrement are at the bottom of the fifth receiving cavity 18, with the filter plate 22 located on the side of the fifth receiving cavity 18 away from the collection tank 17. The connecting block 20 is located above the filter plate 22, above the side of the fifth receiving cavity 18 away from the collection tank 17. Then, the roller chamber 3 begins to rotate counterclockwise, causing the filter plate 22 to gradually move downwards. Since the filter plate 22, the third baffle 23, the connecting block 20, and the inner wall of the fifth receiving cavity 18 form the sixth receiving cavity 30, when the filter plate 22 moves to the bottom of the fifth receiving cavity 18, the litter and excrement will still remain at the bottom of the fifth receiving cavity 18 due to gravity. Since the filter plate 22 has separation holes, the size of which is larger than the size of the litter and smaller than the size of the excrement, the litter can pass through the separation holes into the sixth receiving cavity 30, while the excrement remains on the filter plate 22. Thus, the initial separation of the litter and excrement is achieved through the filter plate 22.

[0095] Then, the drum chamber 3 continues to rotate counterclockwise, and the filter plate 22 moves to the side of the fifth receiving cavity 18 near the collection tank 17. At this time, the cat litter enters the space enclosed by the connecting block 20, the third baffle 23 and the fifth receiving cavity 18, so that the cat litter will not leak out from the filter plate 22. At the same time, the connecting block 20 moves from the top of the fifth receiving cavity 18 away from the collection tank 17 to the bottom of the fifth receiving cavity 18.

[0096] When the connecting block 20 moves to the bottom of the fifth receiving cavity 18, a gap 27 is left between the end of the second guide plate 26 near the inlet 19 and the inner wall of the fifth receiving cavity 18. When the gap 27 moves to the bottom of the fifth receiving cavity 18, the excrement will fall into the gap 27. Since a guide surface 24 is provided on the side of the connecting block 20 away from the third baffle 23, and the distance between the guide surface 24 and the third baffle 23 gradually decreases in the direction away from the inlet 19 of the drum 3, the first guide plate 25 is fixedly connected to the guide surface. 24 is close to the center of the fifth receiving cavity 18, so that the guide surface 24, the first guide plate 25 and the inner wall of the fifth receiving cavity 18 form a space. The discharge port 4 is located on the side wall of the drum chamber 3 away from the inlet 19. In the initial state, the discharge port 4 is located on the side of the drum chamber 3 near the collection tank 17. Therefore, by fixing the second guide plate 26 between the discharge port 4 and the first guide plate 25, in the initial state, the second guide plate 26 is inclined downward from away from the collection tank 17 to near the collection tank 17 inside the drum chamber 3.

[0097] After the excrement falls into the gap 27, the drum 3 begins to rotate clockwise. Under gravity, the excrement remains in place. However, as the drum 3 continues to rotate clockwise, the guide surface 24 pushes the excrement from near the collection trough 17 to away from it. As the guide surface 24 gradually moves upward, the distance between it and the third baffle 23 gradually decreases in the direction away from the inlet 19. Therefore, as the guide surface 24 moves upward, its height gradually decreases in the direction away from the inlet 19. Consequently, the excrement moves away from the inlet 19 due to this height difference. When the end of the guide surface 24 away from the inlet 19 reaches the top of the fifth receiving cavity 18, the excrement... Adjacent to the guide surface 24, the first guide plate 25 supports the excrement. Then, as the drum chamber 3 continues to rotate clockwise, the guide surface 24 pushes the excrement towards the collection trough 17 inside the drum chamber 3. Since the first guide plate 25 is arc-shaped, and when the end of the guide surface 24 away from the inlet 19 is located at the top of the fifth receiving cavity 18, the height of the first guide plate 25 gradually decreases from away from the collection trough 17 to closer to the collection trough 17 inside the drum chamber 3. Therefore, after the drum chamber 3 continues to rotate clockwise, the excrement will slide down along the arc of the first guide plate 25 onto the second guide plate 26. Since the second guide plate 26 in its initial position is inclined downward from away from the collection trough 17 to closer to the collection trough 17 inside the drum chamber 3, the excrement will slide down along the second guide plate 26 until it is discharged from the excrement outlet 4.

[0098] Furthermore, as the excrement moves upwards, the filter plate 22 returns from the side of the fifth receiving cavity 18 closest to the collection trough 17 to the side furthest from the collection trough 17. During this process, the cat litter, under the influence of gravity, is discharged from the sixth receiving cavity 30. The cat litter passes through the separation holes on the filter plate 22 and returns to its initial position, the bottom of the fifth receiving cavity 18, so that the cat can defecate again later. Traditionally, after cleaning up the excrement with a cat scoop, the cat litter needs to be turned over and leveled with the scoop. However, in this invention, the cat litter, after sliding from the sixth receiving cavity 30 to the bottom of the fifth receiving cavity 18, will cover the bottom of the fifth receiving cavity 18, eliminating the need for further turning over and further reducing the number of steps.

[0099] By following the steps above, the separation of cat litter and excrement can be completed simply by rotating the roller chamber 3 counterclockwise and clockwise in sequence. The operation is simple and greatly improves the efficiency of cleaning up excrement. In addition, the diffusion of excrement odor can be reduced by opening an inlet 19 on the roller chamber 3.

[0100] like Figures 10 to 13 As shown, in one embodiment of this utility model, the angle formed between the connecting block 20 and the third baffle 23 on the side closer to the third baffle 23 is greater than 100 degrees.

[0101] By increasing the angle between the connecting block 20 and the third baffle 23 on the side closer to the third baffle 23 by more than 100 degrees, the space of the sixth accommodating cavity 30 can be increased. At the same time, the space enclosed by the third baffle 23, the connecting block 20 and the fifth accommodating cavity 18 is also increased, so that when the roller chamber 3 rotates counterclockwise, cat litter will not leak from the filter plate 22, and cat litter and excrement will be prevented from being discharged from the defecation outlet 4 together.

[0102] like Figure 10 , Figure 12 and Figure 16 As shown, in one embodiment of the present invention, a fourth baffle 28 is fixedly connected between the second guide plate 26 and the inner wall of the fifth accommodating cavity 18.

[0103] By fixing two fourth baffles 28 between the second guide plate 26 and the inner wall of the fifth receiving cavity 18, the excrement can only slide downward between the two fourth baffles 28. The fourth baffles 28 can limit the excrement and prevent it from sliding out from one side of the second guide plate 26, ensuring that the excrement can slide down the second guide plate 26 to the discharge port and be discharged outside the roller chamber 3.

[0104] like Figure 10 , Figure 11 , Figure 13 and Figure 16As shown, in one embodiment of this utility model, one end of a third guide plate 29 is fixedly connected to the first guide plate 25, and the other end of the third guide plate 29 is connected to the end of the guide surface 24 near the inlet 19. The angle between the side of the third guide plate 29 near the second guide plate 26 and the first guide plate 25 is greater than 90 degrees and less than 180 degrees.

[0105] By fixing one end of the third guide plate 29 to the first guide plate 25, and connecting the other end of the third guide plate 29 to the end of the guide surface 24 near the inlet 19, when the excrement slides to the end of the first guide plate 25 away from the inlet 19, it will slide onto the third guide plate 29 under the action of inertia. Since the angle between the side of the third guide plate 29 near the second guide plate 26 and the first guide plate 25 is greater than 90 degrees and less than 180 degrees, the excrement is prevented from getting stuck in the gap between the end of the first guide plate 25 away from the inlet 19 and the drum chamber 3. Therefore, the excrement will slide onto the second guide plate 26 under the action of gravity, and then slide out of the discharge port 4 along the second guide plate 26 under the action of gravity. The third guide plate 29 can ensure that the excrement is smoothly discharged outside the drum chamber 3.

[0106] This utility model has the following advantages:

[0107] 1. By sliding the collection component inside the first receiving cavity 2, the collection component can collect the cat litter carried by the cat's paw, reducing the amount of cat litter falling onto the ground and reducing the difficulty of cleaning.
