[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0047] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood 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 solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with 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 body 2, a lower basin body 3 and a sand leakage mechanism 4. The main body 1 can be a shell or frame of the cat litter box, the upper basin body 2 can be fixedly mounted on the main body 1 by bolts or buckles, etc., the upper basin body 2 is used to load cat litter and provide a toilet for cats, and a cat litter cleaning device 1000 can be arranged in the upper basin body 2, and the cat litter cleaning device 1000 is, for example, a mobile rake device.

[0050] The bottom of the upper basin body 2 is provided with a sand outlet 22, which is used to leak cat litter in the upper basin body 2. The sand leaking mechanism 4 is installed at the bottom 21 of the upper basin body 2, and the sand outlet 22 can be opened or closed.

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

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

[0053] Therefore, the automatic litter cleaning cat litter box does not need to remove the upper basin body 2 for loading cat litter, but the cat litter in the upper basin body 2 is transferred to the lower basin body 3 through the sand leakage mechanism 4, and then the lower basin body 3 is removed to pour out the cat litter, and the 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 litter cleaning cat litter box.

[0054] Further, the sand leakage mechanism 4 includes a swing rod 41, a baffle 42 and a driving member 43. The swing rod 41 is directly or indirectly rotatably mounted on the bottom 21 of the upper basin body 2. The baffle 42 is slidably mounted on the bottom 21 of the upper basin body 2 and connected to the swing rod 41, and the baffle 42 opens or closes the sand falling opening 22. The driving member 43 is drivingly connected to the swing rod 41 to drive the swing rod 41 to swing and drive the baffle 42 to slide, thereby opening or closing the sand falling opening 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 rod 41 has a first end 411 and a second end 412, and the first end 411 of the swing rod 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 rod 41 to rotate around its first end 411, and the second end 412 of the swing rod 41 is connected to the baffle 42, thereby realizing the driving of the baffle 42.

[0056] In other embodiments, as shown in the attached Figure 7As 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 part of the swing rod 41 is directly rotatably connected to the bottom 21 of the upper basin body 2. In addition, the first end 411 of the swing rod 41 is rotatably connected to the output shaft of the electric push rod, and the second end 412 of the swing rod 41 is rotatably 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 around the middle part of itself, thereby realizing the driving of the baffle 42.

[0057] For further information, see Appendix 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 in an arc shape, and the baffle 42 slides in the slide groove 23.

[0058] In order to better utilize the limited space of the bottom 21 of the upper basin body 2, in the preferred embodiment, the chute 23 is extended in a straight line, and an adapting groove 421 perpendicular to the chute 23 is provided on the baffle 42. Specifically, an adapting boss 422 extending downward is provided on the bottom surface 420 of the baffle 42, and an adapting groove 421 is provided in the adapting boss 422. A connecting boss 4121 is provided on the second end 412 of the swing rod 41, and the connecting boss 4121 is located in the adapting groove 421 and can slide along the adapting groove 421. During the swinging process of the second end 412, there are sub-movements perpendicular to the chute 23 and sub-movements parallel to the chute 23. The sub-movement of the second end 412 perpendicular to the chute 23 is reflected in the sliding 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 a larger drop opening and a baffle 42 of corresponding size to be provided, thereby increasing the drop rate of the cat litter.

[0059] For the convenience of mold opening and cost saving of raw materials, in this embodiment, the automatic cat litter box also includes at least two guide rails 5. Taking 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 abut against the two guide rails 5 at the same time, 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 methods. The vertical section of the guide rails 5 is preferably designed in a "Z" shape. 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 abuts on the receiving plate 53.

[0060] Furthermore, the number of the swing rod 41, the baffle 42 and the driving member 43 are all two, and they are respectively arranged in mirror symmetry, so as to allow the litter outlet to be designed wider and accelerate the speed of the cat litter falling. In addition, in order to prevent the cat litter on the lower basin 3 from accumulating in a cone shape and blocking the litter outlet 22, in this embodiment, a combing structure 423 extending downward in height is provided on the bottom surface 420 of the baffle 42, and the combing structure 423 is also extended in length in a direction perpendicular to the sliding direction of the baffle 42. The movement of the baffle 42 can drive the combing structure 423 to move synchronously, pushing the cat litter close to the height of the baffle 42 down.

[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] Further, to ensure that the cat litter in the upper basin body 2 can all fall into the lower basin body 3, refer to the attached Figure 3 and 8 The upper basin body 2 in this embodiment includes a basin body 201 and a mounting plate 202. The mounting plate 202 is fixedly mounted on the main body 1. The basin body 201 is mounted on the mounting plate 202. A sand storage chamber 2010 is arranged in the basin body 201. A sand outlet 22 is provided on the basin body 201 and connected to the sand storage chamber 2010. The bottom surface 2011 of the sand storage chamber 2010 is funnel-shaped and is arranged to gather toward the sand outlet 22. The mounting plate 202 is arranged horizontally and connected to the main body by bolts or other means. A connection port 2020 is provided on the mounting plate 202. The connection port 2020 is connected to the sand outlet 22. The baffle 42, the driving member 43, etc. are all mounted on the mounting plate 202. The sliding of the baffle 42 can open or close the connection port 2020, thereby achieving the purpose of opening or closing the sand outlet 22. After the upper basin body 2 is split into the basin body 201 and the mounting plate 202, it can also be convenient for manufacturing and save 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 up and down slightly.

[0064] In addition, in this embodiment, referring to Attachments 3 and 10, a weighing device 2021 is provided on the top surface of the mounting plate 202, and the basin body 201 is 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 to indirectly judge the health status of the cat.
