The terms "including" and "having" and any variations thereof in the specification and claims of this utility model and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this utility model or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0024] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, the utility model is a cat litter box with an inclined rotating structure, comprising a cat litter bin 1 and a cat litter base 2, a cat litter recovery part 11 and an excretion part 12 are provided in the cat litter bin 1, the inclined horizontal surface of the cat litter bin 1 is arranged on the cat litter base 2, and the cat litter recovery part 11 and the excretion part 12 are arranged diagonally, a sand filter net 111 is provided on the cat litter recovery part 11, a discharge bin door 121 is provided in the excretion part 12, a collection bin and a rotary drive assembly are provided in the cat litter base 2, the cat litter bin 1 is connected to the moving end of the rotary drive assembly, a bin door limiting platform 21 and a feeding window 22 are provided on the upper end of the cat litter base 2, and the feeding window 22 is communicated with the collection bin.

[0027] By setting the cat litter box in an inclined horizontal plane, and coordinating the diagonal arrangement between the cat litter recovery part 11 and the excretion part 12, and coordinating with the rotary drive component to achieve rotation, it effectively replaces the traditional situation of using support arms on both sides to control the rotation of the cat litter bin 1. This solution installs the rotary drive component in the cat litter base 2, reducing the volume of the product occupied by the rotary drive component, reducing the materials and costs required for production, and adopting an inclined setting, which can effectively reduce the pressure on the rotary drive component caused by the weight of the cat litter box. The cat litter base 2 supports the cat litter bin 1 and shares part of the weight, so that the rotary drive component is less resistant during operation and the drive is smoother. A low-power rotary drive component can be used instead, thereby reducing the noise generated during operation.

[0028] During operation, the cat litter bin 1 is driven to rotate by the setting of the rotary drive component, changing the relative position between the discharge bin door 121 and the cat litter base 2, first recovering the uncontaminated cat litter into the cat litter recovery part 11, and isolating the contaminated cat litter outside the sand filter net 111 and storing it in the discharge part 12; when the discharge bin door 121 rotates to the feed window 22, the discharge bin door 121 opens, and the contaminated cat litter is transferred from the feed window 22 to the collection bin; after the transfer is completed, the cat litter bin 1 rotates in the opposite direction, and the door of the cat litter bin 1 is automatically closed under the action of the bin door limit platform 21; and then the clean cat litter enters the discharge part 12 from the sand filter net 111, realizing automatic cleaning of the cat litter.

[0029] The door of the cat litter bin 1 in this solution is tilted upward at 30 degrees to the horizontal plane. Obviously, the cat litter bin 1 in this solution is tilted, and the tilt angle is not limited. As long as the rotary drive component can drive the cat litter bin 1 to rotate from the bottom, and the clean cat litter can be automatically recovered and the contaminated cat litter can be automatically transferred during the rotation, it will be sufficient.

[0030] A rotating spherical surface is provided on one end of the cat litter bin 1 facing the cat litter base 2, and an arc groove matching the rotating spherical surface is provided on the upper end of the cat litter base 2.

[0031] The provision of the arc groove can better support the cat litter box and make the position between the cat litter bin 1 and the cat litter base 2 more stable.

[0032] A plurality of supporting anti-wear rollers 211 cooperating with the rotating spherical surface are arranged in the arc groove, and the cat litter bin 1 is arranged above the supporting anti-wear rollers 211 .

[0033] By providing the supporting anti-wear roller 211 , it is possible to effectively prevent the rotating spherical surface from contacting the arc groove and causing wear on the rotating spherical surface.

[0034] One end of the discharge bin door 121 is hinged to the main body of the cat litter bin 1 , and a plurality of bin door limiting ridges 212 are provided on the bin door limiting platform 21 , which can limit the lower end surface of the discharge bin door 121 .

[0035] The discharge bin door 121 is hinged at one end and unconnected at the other end. It can be opened by gravity. Due to the characteristics of the rotating spherical arc surface, the cat litter bin 1 rotates to the bin door limit platform 21 and gradually closes, realizing the automatic opening and closing of the discharge bin door 121.

[0036] When the anti-wear roller 211 is supported to lift the cat litter bin 1 to a certain distance, the discharge bin door 121 can be closed more tightly by setting the bin door limiting convex strip 212, thereby effectively avoiding the situation of sand leakage.

[0037] When the discharge bin door 121 is not completely rotated to the feed window 22, there is always at least one bin door limiting convex strip 212 to support the discharge bin door 121 to prevent the discharge bin door 121 from opening.

[0038] The rotary drive assembly includes a rotary driving wheel 31, a rotary driven wheel 32 and a rotary drive device. A rotary connecting member 4 is provided on the cat litter bin 1. The rotary driving wheel 31 is fixedly connected to the moving end of the rotary drive device. The rotary driving wheel 31 is engaged with the rotary driven wheel 32, and the rotary driven wheel 32 is fixedly connected to the rotary connecting member 4.

[0039] The rotating driving device drives the rotating driving wheel 31 to rotate, and the rotating driven wheel 32 is linked to rotate. In conjunction with the setting of the rotating connecting member 4, the cat litter bin 1 can be effectively driven to rotate.

[0040] The rotary connector 4 includes a rotary mounting seat and a rotary connecting column arranged on the rotary mounting seat. The rotary connecting column is provided with an anti-fouling limiting plane 41. The rotary driven wheel 32 is provided with a connecting mounting hole 321. The shape of the connecting mounting hole 321 is adapted to the rotary connecting column.

[0041] By setting the anti-foolproof limit plane 41, the situation of incorrect installation of the rotating connecting member 4 can be effectively reduced, and the position between the rotating connecting column and the rotating driven wheel 32 can be ensured to be fixed, reducing the possibility of idling between the rotating driven wheel 32 and the rotating connecting column.

[0042] The cat litter base 2 is also provided with a disengaging assembly, and a snap-on portion 42 is provided on the outer periphery of the rotating connector 4. The disengaging assembly includes an opening assembly, a snap-on clip 51 and a snap-on mounting frame 52. One end of the snap-on clip 51 is fixedly provided on the snap-on mounting frame 52, and the other end of the snap-on clip 51 is snap-on with the snap-on portion 42, and the snap-on clip 51 is provided with an opening 511.

[0043] By setting the detachable component, the cat litter bin 1 and the cat litter base 2 can be separated, and can be flexibly removed during transportation or when cleaning is required, thereby improving the user experience.

[0044] Furthermore, the component can open the opening 511 by means of the setting of the opening component so that the snap clip 51 is separated from the clamping portion 42 , thereby achieving flexible removal.

[0045] The expansion assembly includes a foot-operated swinging plate 53, a swinging mounting frame 54 and a dismounting lifting block 55. The foot-operated swinging plate 53 is rotatably connected to the swinging mounting frame 54. The upper and lower ends of the dismounting lifting block 55 are respectively provided with expansion protrusions 551 and lifting guide holes 552. The foot-operated swinging plate 53 includes a foot-operated end and a driving end. A foot-operated window 23 cooperating with the foot-operated end is provided on the cat litter base 2. The foot-operated end extends out of the foot-operated window 23. The driving end is provided in the lifting guide hole 552. A lifting guide part 553 is provided on the dismounting lifting block 55. A lifting motion guide 61 cooperating with the lifting guide part 553 is provided in the cat litter base 2.

[0046] Through the setting of the foot-operated swing plate 53, the driving end only needs to be pressed to move upward. During the movement process, the driving end moves in the lifting movable guide hole 552. At the same time, under the cooperation of the lifting guide part 553 and the lifting motion guide member 61, it performs an upward movement, driving the expansion protrusion 551 to gradually approach the opening 511, and finally expand the opening 511, so that the snap clip 51 is disengaged from the snap-connecting part 42, and the cat litter bin 1 can be taken out, thereby improving the user experience.

[0047] There are two lifting motion guide members 61, and the number of lifting guide parts 553 is also two. The two lifting guide parts 553 are respectively arranged on both sides of the de-bin lifting block 55. The two lifting motion guide members 61 are matched with the two lifting guide parts 553 one by one. The lifting guide part 553 is a guide groove arranged on the de-bin lifting block 55. The lifting motion guide member 61 is a lifting motion guide plate, and a guide block that cooperates with the guide groove is provided on the lifting motion guide plate.

[0048] By providing the two lifting motion guide members 61 , the warehouse-ejecting lifting block 55 can be limited and the warehouse-ejecting lifting block 55 can be stably guided at the same time.

[0049] The clamping portion 42 is an annular clamping groove arranged on the periphery of the rotating connecting column. The clamping clip 51 is provided with an annular contoured surface that cooperates with the annular clamping groove, so that the clamping clip 51 and the annular clamping groove fit more closely, ensuring the stability of the position between the clamping clip 51 and the rotating connecting column.

[0050] An ejection block 554 is further provided at the upper end of the debinding lifting block 55 . The height of the ejection block 554 is lower than the supporting protrusion 551 . The ejection block 554 can lift up the rotating connector 4 .

[0051] By setting the ejection block 554, after the expansion block 551 expands the snap clip 51, the disengaging lifting block 55 continues to rise, and the ejection block 554 pushes the rotating connecting column upward for a certain distance, making it convenient for the user to take the detached cat litter bin 1, further improving the user experience.

[0052] The cat litter base 2 is also provided with a millimeter wave radar, which can determine whether there is a living body in the cat litter bin 1 by detecting the heart rate.

[0053] Through the setting of millimeter-wave radar, cat litter box safety operation can be more accurate than other traditional sensors, such as infrared sensors, distance sensors or release sensors, etc. It can identify the heart rate and movements of pets, perform liveness detection, improve the safety of equipment use, and reduce the possibility of misjudgment.

[0054] The cat litter bin 1 is hemispherical in shape, the rotating connector 4 is arranged at the center of the cat litter bin 1 , and the rotation axis direction of the cat litter bin 1 is coaxial with the radius direction of the cat litter bin 1 .

[0055] By coaxially rotating, the cat litter bin 1 can rotate more stably.

[0056] A material collection drawer 24 is provided in the cat litter base 2 , and a material collection bin is provided in the material collection drawer 24 .

[0057] As can be seen from the above, the beneficial effect of the utility model is that: by adopting its mechanism, it can effectively solve the problem that the cat litter box in the prior art uses support arms on both sides to drive the cat litter bin 1 to rotate, which makes the product bulky and complex in structure. By using this product structure, the cat litter bin 1 is tilted, and the rotary drive component is arranged in the cat litter base 2. The rotary drive component drives the cat litter bin 1 above. While ensuring automatic cleaning of the cat litter, the drive structure of the cat litter bin 1 can be effectively simplified, thereby reducing production costs and helping to improve the competitiveness of the product.
