[0056] 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.

[0057] 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.

[0058] 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.

[0059] See attached Figures 1 to 12 The present invention provides a cat litter cleaning device, including a sand storage component 2, a garbage storage component 3, a first sand cleaning component 4, a first driving mechanism 5, a second sand cleaning component 6 and a second driving mechanism 7.

[0060] The sand storage member 2 is provided with a sand cavity 20, and the sand cavity 20 has a first end 201 and a second end 202. The garbage storage member 3 is arranged beside the sand storage member 2 and close to the second end 202, and a garbage cavity 30 is provided in the garbage storage member 3, and an opening 301 connected to the garbage cavity 30 is opened on the top of the garbage storage member 3. The first sand cleaning member 4 includes a first connecting portion 41 and a first sand cleaning portion 42 arranged on the first connecting portion 41, and the first sand cleaning portion 42 extends into the sand cavity 20. The first driving mechanism 5 is drivingly connected to the first connecting portion 41, and is used to drive the first sand cleaning portion 42 to translate from the first end 201 to the second end 202, or to drive the first sand cleaning portion 42 to translate from the second end 202 to the first end 201. The second sand cleaning member 6 includes a second connecting portion 61 and a second sand cleaning portion 62 arranged on the second connecting portion 61 . The second connecting portion 61 is rotatably arranged. The second driving mechanism 7 is drivingly connected to the second connecting portion 61 for driving the second sand cleaning portion 62 to rotate around the first connecting portion 41 .

[0061] The second sand cleaning member 6 has a first state in which the second sand cleaning portion 62 extends into the second end 202, and a second state in which the second sand cleaning portion 62 rotates to be higher than the opening 301 and tilts toward the opening 301. When the second sand cleaning member 6 is in the second state, the angle between the second sand cleaning portion 62 and the horizontal plane is between 30° and 60°.

[0062] The first sand cleaning part 42 is driven to move from the first end 201 to the second end 202, and the feces in the sand chamber 20 are concentrated at the second end 202, and then returned to the first end 201. During this movement, the first sand cleaning part 42 also implements a flattening operation on the cat litter in the sand chamber 20. In the initial state, the second sand cleaning part 6 is in the first state. When the second sand cleaning part 6 is started, it will change to the second state, and the feces accumulated at the second end 202 will be taken out of the sand chamber 20 by the second sand cleaning part 62. As the second sand cleaning part 62 rises, the second sand cleaning part 62 will be higher than the opening 301 and tilted toward the opening 301, so that the feces carried on the second sand cleaning part 62 rolls down along the second sand cleaning part 62 into the garbage storage part 3, thereby completing the cleaning of the cat litter. After the feces rolls down to the garbage storage part 3, the second sand cleaning part 6 will return to the first state.

[0063] In the above-mentioned sand cleaning process, the first sand cleaning member 4 and the second sand cleaning member 6 both have the effect of filtering cat litter, that is, the above-mentioned sand cleaning process screens the cat litter twice in total, which can improve the reliability of cat litter cleaning on the one hand, and filter the cat litter more fully on the other hand, saving the amount of cat litter consumed. In the existing cat litter box with a single rake for multi-directional movement, at least a part of the wire needs to be connected to the rake and move with the rake, and the wire is prone to being entangled, pulled, etc., resulting in a short life of the wire and a high failure rate. Therefore, the first sand cleaning member 4 and the second sand cleaning member 6 of the present embodiment both move in a single direction, and no additional electrical components need to be connected to the first sand cleaning member 4 and the second sand cleaning member 6, so that the first drive mechanism 5 and the second drive mechanism 7 can both adopt a fixed installation structure, and the wire does not need to move with the first sand cleaning member 4 or the second sand cleaning member 6, so as to prevent the wire from being entangled and stretched, thereby improving the service life of the cat litter cleaning device.

[0064] In addition, the sand storage member 2 and the garbage storage member 3 can be connected by a connecting frame 11 to keep the positions of the two fixed.

[0065] Of course, in other embodiments, the cat litter cleaning device may not need to be equipped with the litter storage unit 3 , and the user may place a litter bin beside the litter storage unit 2 .

[0066] Furthermore, in order to improve the reliability of the sand cleaning results, Figure 4 , 5As shown in Figures 6 and 7, in this embodiment, the first connecting portion 41 is arranged in a rod shape and extends along the width direction of the sand storage member 2, and the first sand cleaning portion 42 includes a plurality of first cleaning teeth 421 distributed along the length direction of the first connecting portion 41, and the first cleaning teeth 421 extend into the sand cavity 20; the second connecting portion 61 is also arranged in a rod shape and extends along the width direction of the sand storage member 2, and the second sand cleaning portion 62 includes a plurality of second cleaning teeth 621 distributed along the length direction of the second connecting portion 61. When the first sand cleaning portion 42 moves to the second end 202, the plurality of first cleaning teeth 421 and the plurality of second cleaning teeth 621 are arranged alternately to ensure that the feces are concentrated on the second cleaning teeth 621, and the second cleaning teeth 621 can take away all the feces after swinging. Of course, in other embodiments, the first cleaning tooth 421 and the second cleaning tooth 621 may not be staggered with each other, but the first cleaning tooth 421 is designed to be higher than the second cleaning tooth 621, that is, after the first cleaning tooth 421 moves to the second end 202, the vertical projections of the first cleaning tooth 421 and the second cleaning tooth 621 have overlapping parts or are staggered with each other, thereby achieving the same technical effect as the previous embodiment.

[0067] As attached Figure 5 As shown, the plurality of first cleaning teeth 421 include a flat push portion 4211 and a hook portion 4212, the flat push portion 4211 is connected to the first connecting portion 41, the flat push portion 4211 extends downward and is connected to the hook portion 4212, the hook portion 4212 and the flat push portion 4211 have an angle and extend laterally toward the second end 202. The flat push portion 4211 and the hook portion 4212 are both rod-shaped and integrally bent, the flat push portion 4211 is used to push the feces block and the filter sand, and the hook portion 4212 is used to prevent the feces block from detaching from the flat push portion 4211 from below the flat push portion 4211.

[0068] As attached Figure 5 As shown, each second cleaning tooth 621 includes a guide portion 6211, a receiving portion 6212 and a blocking portion 6213, wherein the guide portion 6211 is connected to the second connecting portion 61, and when the second sand cleaning member 6 is in the first state, the guide portion 6211 extends downward and connects the receiving portion 6212, and there is an angle between the receiving portion 6212 and the guide portion 6211, and the receiving portion 6212 extends laterally toward the first end 201 and connects the blocking portion 6213, and there is an angle between the blocking portion 6213 and the receiving portion 6212 and extends upward. Specifically, the guide portion 6211 and the receiving portion 6212 are arranged at an obtuse angle, and the blocking portion 6213 and the receiving portion 6212 are also arranged at an obtuse angle. The guide portion 6211, the receiving portion 6212 and the blocking portion 6213 are all rod-shaped structures and are bent as one piece, for example, they are formed by bending an iron rod. The receiving portion 6212 and the blocking portion 6213 are used to hook the feces block to prevent the feces block from falling back into the sand chamber 20 during the rotation of the second cleaning tooth 621; when the second sand cleaning member 6 is in the second state, the guiding portion 6211 is used to guide the falling direction of the feces block.

[0069] As attached Fig. 9 As shown, the second connecting portion 61 is arranged in a bent plate structure, and has an offset portion 612 and a sand retaining portion 613. The offset portion 612 is connected to the second driving mechanism 7, and the sand retaining portion 613 is arranged in a plate shape and is parallel to the rotation axis 60 of the second sand cleaning member 6. The sand retaining portion 613 is connected to the offset portion 612. Due to the existence of the offset portion 612, the sand retaining portion 613 is arranged to deviate from the rotation axis 60 of the second sand cleaning member 6, and the second cleaning teeth 621 are extended to the side of the sand retaining portion 613 away from the offset portion 612. In addition, the sand retaining portion 613 at least extends and crosses the rotation axis 60 of the second sand cleaning member 6 to the vertical line 601 of the sand retaining portion 613 itself. The offset portion 612 can also be set in a plate-like structure, so there is an angle between the offset portion 612 and the sand retaining portion 613, and the angle range is between 50 degrees and 80 degrees. When the second sand cleaning member 6 is in the first state, the offset portion 612 is horizontally arranged, and the sand retaining portion 613 extends downward. Therefore, when the second sand cleaning member 6 is in the second state, as shown in the attached Figure 7 As shown, the feces block can be prevented from remaining in the rotation gap between the offset portion 612 and the sand storage member 1 when sliding down the guide portion 6211 toward the opening.

[0070] Regarding the structure of the first driving mechanism 5, as shown in the attached Figure 5 As shown, in this embodiment, the first driving mechanism 5 specifically includes a driving rod 51, a pushing block 52 and a first driving member 53. The driving rod 51 is arranged beside the sand storage member 2 along the length direction of the sand storage member 2. The first connecting portion 41 is installed on the pushing block 52. The first driving member 53 is used to drive the pushing block 52 to translate along the driving rod 51. Specifically, the driving rod 51 has a thread, the driving rod 51 penetrates the pushing block 52 and is threadedly connected with the pushing block 52. The first driving member 53 is a motor. The first driving member 53 is used to drive the driving rod 51 to rotate around its own axis, thereby driving the pushing block 52 to translate on the driving rod 51. In order to ensure that the pushing block 52 only performs linear motion, a guide structure that cooperates with the pushing block 52 can also be provided, such as a guide rail, a guide groove and other structures.

[0071] Further, in order to make the force of the first sand cleaning member 4 more balanced, in this embodiment, a push block 52 is connected to both sides of the first sand cleaning member 4, and the first driving mechanism 5 also includes a guide rod 54, which is arranged in parallel with the driving rod 51, and the guide rod 54 and the driving rod 51 are respectively arranged on the opposite sides of the sand storage member 2. The two push blocks 52 are penetrated by the driving rod 51 and the guide rod 54, respectively, and the first connecting portion 41 is installed on the two push blocks 52 at the same time. As for the connection structure between the first connecting portion 41 and the push block 52, in this embodiment, a first embedded groove 521 extending downward is provided on the push block 52, and the side end 411 of the first connecting portion 41 is embedded in the first embedded groove 521 from top to bottom in an interference fit manner. In order to improve the connection stability between the first connecting portion 41 and the push block 52, the side end 411 of the first connecting portion 41 can also be arranged in a "U" shape, and the shape of the first embedded groove 521 can be arranged accordingly.

[0072] Regarding the structure of the second driving mechanism 7, in this embodiment, the second driving mechanism 7 includes a rotating member 71 and a second driving member 72. The rotating member 71 is rotatably arranged beside the sand storage member 2, the second connecting portion 61 is connected to the rotating member 71, and the second driving member 72 also uses a motor. The rotating member 71 is directly connected to the output shaft of the second driving member 72. The second driving member 72 is used to drive the rotating member 71 to rotate, so as to drive the second sand cleaning member 6 to enter the first state or the second state. When the second sand cleaning member 6 is in the first state, the plurality of second cleaning teeth 621 extend into the sand cavity 20; when the second sand cleaning member 6 is in the second state, the plurality of second cleaning teeth 621 are higher than the opening 301 and tilted toward the opening 301.

[0073] Among them, as attached Figure 5 As shown, the rotating member 71 may be provided with a second engaging groove 711 extending vertically to the rotating shaft thereof, and the side end 611 of the second connecting portion 61 is inserted into the second engaging groove 711 from top to bottom in an interference fit manner. The rotating axis of the rotating member 71 is the rotating axis 60 of the second sand cleaning member 6.

[0074] Furthermore, the cat litter cleaning device further comprises a bucket cover 8 and a third driving mechanism 9. The bucket cover 8 is rotatably arranged above the garbage storage part 3 and can cover the opening 301. The third driving mechanism 9 is used to drive the bucket cover 8 away from the second end 202 to open the opening 301. The bucket cover 8 is used to receive the cat and prevent the cat from falling into the garbage cavity 30. In addition, the bucket cover 8 is hollowed out, and when the cat stands on the bucket cover 8, the cat litter stuck on the cat's feet can fall into the garbage storage part 3. In addition, a funnel-shaped structure 31 that gathers toward the opening 301 can be provided on the garbage storage part 3 to collect feces at the opening 301, and a garbage bag and a bag sealing device can be installed at the opening 301, so that the feces are collected in the garbage bag, and then the garbage bag is sealed by the bag sealing device.
