[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0047] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0049] See attached Figures 1 to 10 The present invention provides an automatic litter box, comprising a main body 1, an upper basin 2, a lower basin 3, and a sand draining mechanism 4. The main body 1 can be the outer shell or frame of the litter box, and the upper basin 2 can be fixed to the main body 1 by bolts or snaps. The upper basin 2 is used to store cat litter and provide a toilet for cats. A cat litter cleaning device 1000, such as a mobile rake, can be disposed within the upper basin 2.

[0050] Among them, the bottom of the upper basin body 2 is provided with a sand outlet 22, which is used to leak out the cat litter in the upper basin body 2. The sand leakage mechanism 4 is installed at the bottom 21 of the upper basin body 2 and can open or close the sand outlet 22.

[0051] When the sand leakage mechanism 4 is closed, the sand leakage mechanism 4 blocks the sand outlet 22 to prevent cat litter from falling from the sand outlet 22; when the sand leakage mechanism 4 is opened, the sand leakage mechanism 4 opens the sand outlet 22 to allow cat litter to pass through the sand outlet 22.

[0052] The lower basin body 3 is located below the upper basin body 2 and can be slidably mounted on the main body 1. Figure 2 As shown, a drawer opening 10 is provided on the side of the main body 1, through which the lower basin 3 can slide sideways into the main body 1. The lower basin 3 has a first state in which it is located directly below the upper basin 2, and a second state in which it slides away from the main body 1. When the lower basin 3 is in the first state, the sand outlet 22 faces the lower basin 3. At this time, the sand draining mechanism 4 can be opened to allow the cat litter in the upper basin 2 to fall into the lower basin 3. After the cat litter in the upper basin 2 has fallen out, the sand draining mechanism 4 is closed, and the lower basin 3 is pushed and pulled to the second state, so that the lower basin 3 is separated from the main body 1. The cat litter removal work can then be completed by removing the cat litter in the lower basin 3.

[0053] Therefore, the automatic cat litter cleaning box does not need to remove the upper basin body 2 for loading cat litter. Instead, the cat litter in the upper basin body 2 is transferred to the lower basin body 3 through the sand leakage mechanism 4. The lower basin body 3 is then removed to pour out the cat litter, and new cat litter is refilled into the upper basin body 2 to complete the work of replacing the cat litter, making it very convenient to replace the cat litter in the automatic cat litter cleaning box.

[0054] Furthermore, the sand leakage mechanism 4 includes a swing arm 41, a baffle 42, and a driving member 43. The swing arm 41 is directly or indirectly rotatably mounted on the bottom 21 of the upper basin 2. The baffle 42 is slidably mounted on the bottom 21 of the upper basin 2 and connected to the swing arm 41. The baffle 42 opens or closes the sand dropout 22. The driving member 43 is drivingly connected to the swing arm 41, driving the swing arm 41 to swing and slide the baffle 42, thereby opening or closing the sand dropout 22.

[0055] In one embodiment, as shown in the attached Figures 4 to 6 As shown, the driving member 43 is a motor, which is fixedly mounted on the bottom 21 of the upper basin body 2. The swing arm 41 has a first end 411 and a second end 412. The first end 411 of the swing arm 41 is fixedly connected to the output shaft of the motor. The rotation of the motor output shaft can drive the second end 412 of the swing arm 41 to rotate about its first end 411. The second end 412 of the swing arm 41 is connected to the baffle 42, thereby driving the baffle 42.

[0056] In other embodiments, as shown in the attached Figure 7 As shown, the driving member 43 is an electric push rod, which is fixedly mounted on the bottom 21 of the upper basin body 2. The swing rod 41 has a first end 411 and a second end 412, and the middle portion of the swing rod 41 is directly and rotationally connected to the bottom 21 of the upper basin body 2. In addition, the first end 411 of the swing rod 41 is rotationally connected to the output shaft of the electric push rod, while the second end 412 of the swing rod 41 is rotationally connected to the baffle 42. The telescopic movement of the output shaft of the electric push rod can drive the second end 412 and the first end 411 of the swing rod 41 to rotate about their own middle portions, thereby driving the baffle 42.

[0057] For further information, see the attached Figure 4 、 7 And 9, regarding the sliding structure of the baffle 42, in one embodiment, a slide groove 23 is provided at the bottom 21 of the upper basin body 2, and the slide groove 23 is extended in a straight line or an arc shape, and the baffle 42 slides in the slide groove 23.

[0058] To better utilize the limited space at the bottom 21 of the upper basin body 2, in the preferred embodiment, the chute 23 extends linearly, while the baffle 42 defines an adapting groove 421 perpendicular to the chute 23. Specifically, a downwardly extending adapting boss 422 is provided on the bottom surface 420 of the baffle 42, with the adapting groove 421 defined within the adapting boss 422. A connecting boss 4121 is provided on the second end 412 of the swing arm 41. The connecting boss 4121 is positioned within the adapting groove 421 and can slide along the adapting groove 421. During the swinging motion of the second end 412, there are two sub-movements perpendicular to the chute 23 and parallel to the chute 23. The sub-movement of the second end 412 perpendicular to the chute 23 is manifested by the sliding movement of the connecting boss 4121 along the adapting groove 421, while the sub-movement of the second end 412 parallel to the chute 23 drives the baffle 42 to move linearly along the chute 23. Therefore, a part of the space of the sand leakage mechanism 4 in the direction perpendicular to the chute 23 can be saved, allowing the provision of a larger drop opening and a baffle 42 of corresponding size, thereby increasing the drop rate of the cat litter.

[0059] For the convenience of mold opening, saving of raw materials and other cost considerations, in this embodiment, the automatic cat litter box also includes at least two guide rails 5. Taking the two guide rails 5 as an example, the two guide rails 5 are arranged in parallel and installed on the bottom 21 of the upper basin body 2. The two guide rails 5 form a slide 23. Both sides of the baffle 42 are simultaneously against the two guide rails 5, and the baffle 42 slides along the guide rails 5. The guide rails 5 can be made of materials such as metal or plastic, and are fixedly installed on the upper basin body 2 by bolts, clamping or other means. The vertical cross-section of the guide rails 5 is preferably a "Z"-shaped design. Specifically, the guide rails 5 include a mounting plate 51, a connecting plate 52 and a receiving plate 53 connected in sequence. The mounting plate 51 and the receiving plate 53 are parallel to each other. The mounting plate 51 is fixed to the upper basin body 2 by bolts, and the baffle 42 is supported on the receiving plate 53.

[0060] Furthermore, the number of rocker arms 41, baffles 42, and drive members 43 is two each, and they are arranged in mirror-symmetrical fashion. This allows for a wider design for the litter dropout opening, accelerating the rate at which the litter falls. Furthermore, to prevent the litter from accumulating in a conical shape on the lower basin 3 and blocking the litter dropout opening 22, in this embodiment, a combing structure 423 extending downward is provided on the bottom surface 420 of the baffle 42. The combing structure 423 also extends in a direction perpendicular to the sliding direction of the baffle 42. The movement of the baffle 42 drives the combing structure 423 to move synchronously, pushing down the litter near the height of the baffle 42.

[0061] Specifically, the combing structure 423 can be a plate-shaped design, or it can be as shown in the attached Figure 6 In the tooth-shaped or rake-shaped design shown, the combing structure 423 is arranged beside the adapting boss 422, and the combing structure 423 and the adapting boss 422 are parallel to each other.

[0062] Furthermore, to ensure that the cat litter in the upper basin 2 can all fall into the lower basin 3, see the attached Figure 3 and 8 The upper basin 2 in this embodiment includes a basin body 201 and a mounting plate 202. The mounting plate 202 is fixedly mounted to the main body 1, and the basin body 201 is mounted on the mounting plate 202. A sand storage chamber 2010 is provided within the basin body 201. A sand dropout port 22 is provided on the basin body 201 and is connected to the sand storage chamber 2010. The bottom surface 2011 of the sand storage chamber 2010 is funnel-shaped and converges toward the dropout port 22. The mounting plate 202 is horizontally arranged and connected to the main body via bolts or other means. A connection port 2020 is provided on the mounting plate 202, which communicates with the dropout port 22. The baffle 42, the driving member 43, and the like are all mounted on the mounting plate 202. The sliding movement of the baffle 42 opens or closes the connection port 2020, thereby opening or closing the dropout port 22. Separating the upper basin 2 into the basin body 201 and the mounting plate 202 facilitates manufacturing and saves materials.

[0063] The basin body 201 may be fixedly mounted on the mounting plate 202 , or the basin body 201 may be allowed to slide slightly up and down.

[0064] In addition, in this embodiment, referring to Appendixes 3 and 10, a weighing device 2021 is provided on the top surface of the mounting plate 202, and the basin body 201 rests against the weighing device 2021. When the weight of the basin body changes, the pressure exerted by the basin body on the weighing device 2021 will also change accordingly, so that the weighing device 2021 can be used to detect the weight change in the basin body 201, so as to indirectly judge the health status of the cat.
